longer lasting sweetness and flavor perception, it may be desirable to encapsulate or otherwise control the release of at least a portion of the artificial sweeteners.","Techniques such as wet granulation, wax granulation, spray drying, spray chilling, fluid bed coating, conservation, encapsulation in yeast cells and fiber extrusion may be used to achieve desired release characteristics.","Encapsulation of sweetening agents can also be provided using another chewing gum component such as a resinous compound.","Usage level of the artificial sweetener will vary considerably and will depend on factors such as potency of the sweetener, rate of release, desired sweetness of the product, level and type of flavor used and cost considerations.","The active level of artificial sweetener may vary from about 0.001 to about 8% by weight, and often ranges from about 0.02 to about 8% by weight.","When carriers used for encapsulation are included, the usage level of the encapsulated sweetener will be proportionately higher.","Combinations of sugar and/or non-sugar sweeteners may be used if desired.","A chewing gum and/or gum base may include one or more

calcium silicate, kaolin, clays, crystalline aluminosilicates, macaloid bentonite, activated carbon, alumina, hydroxylapatite, microcrystalline cellulose, or any combination thereof.","Nicotine may be encapsulated to provide a desired controlled or sustained release thereof.","An example of a chewing gum that provides for sustained release of nicotine is described in U.S. 2007/0014887, the disclosure of which is hereby incorporated by reference.","Alternatively, isomyosmine may be infused into an outer portion of a chewing gum than contains nicotine.","A similar release profile may be achieved via an oral dosage form such as a tablet, capsule, or the like.","For example, a tablet may have a core layer containing nicotine to provide a sustained release thereof, and an outer layer

determining monoamine oxidase (MAO) inhibition for isomyosmine and other alkaloids.","MAOs are enzymes located on the outer membrane of mitochondria and are involved in the catabolism of monoamine neurotransmitters.","There are two well-characterized isoenzymes: MAO-A, which predominantly catabolizes serotonin and norepinephrine, and MAO-B, which preferentially catabolizes benzylamine and phenylethylamine.","Dopamine and tyramine are metabolized by both isoforms.","To detect the activity of MAO, a luminescent method (MAO-Glo Assay kit, from Promega, Cat # V1401) was used.","In this method, a MAO substrate (a derivative of beetle luciferin provided in the kit) is mixed with the compound to be tested (in this case, myosmine and control compounds).","Then, the MAO enzymes (either A or B, purchased separately) are added to the mixture and incubated with the reaction for 1 hour at room temperature.","The MAO enzymes, if not inhibited by the test compound, will convert the substrate into methyl ester luciferin.","Finally, a luciferin detection reagent (provided by the kit) is added (20 minutes at room temperature) to stop the MAO reaction and convert methyl ester luciferin into D-luciferin.","D-luciferin reacts with luciferase to produce a luminescent signal, which is directly proportional to the D-luciferin concentration and thus the MAO activity: the greater the amount of light produced the higher the activity of MAO.","The luminescent signal is measured and recorded using a luminometer.","The following materials were obtained from Toronto Research Chemicals, North York, ON: isomyosmine, catalog #1821350; myosmine, catalog # M835000; anabasine, catalog # A637175; and nornicotine, catalog # N756995.Anatabine was obtained from Emerson Resources, Norristown, Pa. As positive controls for the experiment, clorgyline (a well-characterized potent inhibitor of MAO-A) and deprenyl (a well-characterized potent inhibitor of MAO-B) were used.","Results for MAO-A Activity When the pure alkaloids isomyosmine, myosmine, anatabine, anabasine, and nornicotine were compared, isomyosmine was the most potent of the five in inhibiting the enzymatic activity of MAO-A (FIG.","1).","The way to read this line graph is the following: a 100% activity means that the test compound has no effect on the enzyme; a 0% activity means that the test compound completely kills the enzyme.","The more the curve is shifted to the left, the greater the inhibition the test compound exerts on the enzyme.","As can be seen in FIG.","1, the curve for isomyosmine is more shifted to the left among the five alkaloids tested.","A 2 mM concentration (2,000 micromolar) gives an inhibition of about 50%.","The curve for clorgyline, the positive control for the experiment, is greatly shifted leftward.","Results for MAO-B Activity Similar results were obtained when testing the five pure alkaloids isomyosmine, myosmine, anatabine, anabasine, and nornicotine for the inhibition of MAO-B.","Isomyosmine was the most potent among the five alkaloids tested at inhibiting the activity of MAO-B, followed by myosmine (FIG.","2).","Example 2 This example shows that isomyosmine is effective to increase oxygen saturation (%) levels.","As shown in FIG.","3, oxygen saturation (%) was found to dramatically increase in fourteen individuals when measured one hour after oral administration of isomyosmine at a dose of 100-300 mg depending on body weight.","Increasing oxygen saturation levels is believed to make isomyosmine particularly effective for treating substance addictions, including tobacco/nicotine addictions, as well as addictions to heroin, cocaine, opioids, methadone, d-methamphetamine, barbiturates, alcohol, benzodiazepines, amphetamines, or buprenorphine.","For example, substances such as cocaine are known to cause blood vessels to constrict, resulting in increased heartrate and blood pressure and increased stress on the heart's ability to circulate blood and oxygen through the body.","Increasing oxygen saturation levels may, among other things, counteract these types of effects associated with substance abuse by increasing blood oxygen levels, aiding in the treatment of the underlying addiction.","While the invention has been described with respect to specific examples, those skilled in the art will appreciate that there are numerous variations and permutations of the above described systems and techniques that fall within the spirit and scope of the invention as set forth in the appended claims."]],"string":"[\n [\n

signal is measured and recorded using a luminometer.\",\n \"The following materials were obtained from Toronto Research Chemicals, North York, ON: isomyosmine, catalog #1821350; myosmine, catalog # M835000; anabasine, catalog # A637175; and nornicotine, catalog # N756995.Anatabine was obtained from Emerson Resources, Norristown, Pa. As positive controls for the experiment, clorgyline (a well-characterized potent inhibitor of MAO-A) and deprenyl (a well-characterized potent inhibitor of MAO-B) were used.\",\n \"Results for MAO-A Activity When the pure alkaloids isomyosmine, myosmine, anatabine, anabasine, and nornicotine were compared, isomyosmine was the most potent of the five in inhibiting the enzymatic activity of MAO-A (FIG.\",\n \"1).\",\n \"The way to read this line graph is the following: a 100% activity means that the test compound has no effect on the enzyme; a 0% activity means that the test compound completely kills the enzyme.\",\n \"The more the curve is shifted to the left, the greater the inhibition the test compound exerts on the enzyme.\",\n \"As can be seen in FIG.\",\n \"1, the curve for isomyosmine is more shifted to the left among the five alkaloids tested.\",\n \"A 2 mM concentration (2,000 micromolar) gives an inhibition of about 50%.\",\n \"The curve for clorgyline, the positive control for the experiment, is greatly shifted leftward.\",\n \"Results for MAO-B Activity Similar results were obtained when testing the five pure alkaloids isomyosmine, myosmine, anatabine, anabasine, and nornicotine for the inhibition of MAO-B.\",\n \"Isomyosmine was the most potent among the five alkaloids tested at inhibiting the activity of MAO-B, followed by myosmine (FIG.\",\n \"2).\",\n \"Example 2 This example shows that isomyosmine is effective to increase oxygen saturation (%) levels.\",\n \"As shown in FIG.\",\n \"3, oxygen saturation (%) was found to dramatically increase in fourteen individuals when measured one hour after oral administration of isomyosmine at a dose of 100-300 mg depending on body weight.\",\n \"Increasing oxygen saturation levels is believed to make isomyosmine particularly effective for treating substance addictions, including tobacco/nicotine addictions, as well as addictions to heroin, cocaine, opioids, methadone, d-methamphetamine, barbiturates, alcohol, benzodiazepines, amphetamines, or buprenorphine.\",\n \"For example, substances such as cocaine are known to cause blood vessels to constrict, resulting in increased heartrate and blood pressure and increased stress on the heart's ability to circulate blood and oxygen through the body.\",\n \"Increasing oxygen saturation levels may, among other things, counteract these types of effects associated with substance abuse by increasing blood oxygen levels, aiding in the treatment of the underlying addiction.\",\n \"While the invention has been described with respect to specific examples, those skilled in the art will appreciate that there are numerous variations and permutations of the above described systems and techniques that fall within the spirit and scope of the invention as set forth in the appended claims.\"\n ]\n]"},"source":{"kind":"string","value":"Patent_15875692"}}},{"rowIdx":4494952,"cells":{"text":{"kind":"list

Feb. 20, 2012, all of which are hereby incorporated by reference as if fully set forth herein.","BACKGROUND Field of the Invention The present invention relates to a display device, and more particularly, to a display device with an integrated touch screen and a driving method thereof.","Discussion of the Related Art Touch screens are a type of input device that is included in image display devices such as Liquid Crystal Displays (LCDs), Field Emission Displays (FEDs), Plasma Display Panel (PDPs), Electroluminescent Displays (ELDs), and Electrophoretic Display (EPDs), and allows a user to input predetermined information by applying a pressure (i.e., by pressing or touching) to a touch sensor of a touch screen of the image display device while looking at the image display device.","Particularly, the demand of display devices with an integrated in-cell type touch screen, which include a plurality of built-in elements configuring the touch screen for providing slim portable terminals such as smart phones and tablet Personal Computers (PCs), is recently increasing.","Hereinafter, a related art display device with an integrated touch screen will be described with reference to FIG.","1.FIG.","1 is a diagram illustrating a configuration of a related art display device with an integrated touch screen, and more specifically illustrates a configuration of a display device with an integrated self-capacitive touch screen having an in-cell type.","The related art display device with the integrated self-capacitive touch screen having an in-cell type, as illustrated in FIG.","1, includes: a panel 10 with a built-in touch screen 11; a display driver IC (DD-IC) 20 that is connected to an external system and controls a plurality of gate lines and data lines in the panel 10; a plurality of touch ICs (T-IC1 and T-IC2) 31 and 32 that drive the touch screen 11 in the panel 10.The panel 10 includes m number of electrodes 12, and m number of lines 13 that are respectively extended from the m electrodes 12.Each of the touch ICs 31 and 32 includes m number of touch IC channels respectively corresponding to the m lines 13, for self-capacitive touch sensing.","Since one touch IC channel generally corresponds a line connected to an electrode in one-to-one correspondence relationship, as illustrated in FIG.","1, when the number of lines connected to an electrode is more than the number of channels that are capable of being accommodated by one touch IC, a plurality of touch ICs are required to be used, causing the increase in cost.","In the display device with the integrated touch screen of FIG.","1, each of the electrodes 12 is built in the panel 10 and performs a touch function and a display function, and thus is used as a common electrode for display driving when the display device is driven in a display driving mode, or is used as a touch electrode when the display device is driven in a touch driving mode.","The display driving mode is a display mode for displaying images on the display device, and the touch driving mode is a touch mode for detecting and processing a touch input to the display device.","On the contrary, when the display device is driven in the display driving mode, a common voltage Vcom outputted from inside the display driver IC (DD-IC) 20 is applied to the electrodes 12 through the touch ICs 31 and 32, in which case the touch ICs 31 and 32 need to accommodate a negative voltage when the common voltage Vcom is the negative voltage.","However, the related art touch ICs 31 and 32 cannot accommodate a negative voltage and thus, a special manufacturing process and design for a touch IC that can accommodate the negative voltage are needed, which in turn increases the manufacturing cost of the touch ICs.","Moreover, when the related art touch sensitive display device is driven in the display driving mode, a ground-level voltage instead of a negative voltage may be incidentally supplied to the electrode 12 through the touch IC, thereby causing the degradation of image quality.","To provide a summary on the above-described limitations, the related art display device with the integrated touch screen has at least the following limitations.","First, as the number of touch IC channels matching the respective lines connected to electrodes increases, the number of touch ICs increases, thereby causing the increase in cost for the display device.","Second, a touch IC is separately manufactured by modifying the manufacturing process and design thereof for applying a negative common voltage, thereby causing the increase in the manufacturing cost of the touch IC.","Third, when the related art touch IC is applied to a display device, the ground-level common voltage, instead of the desired negative common voltage, may be incidentally applied to the electrodes in the display driving mode, thereby causing the degradation of image quality.","SUMMARY Accordingly, the present invention is directed to provide a display device with an integrated touch screen that substantially obviates one or more problems due to limitations and disadvantages of the related art.","An aspect of the present invention is directed to provide a display device with an integrated touch screen, which applies a common voltage or a touch scan signal to a plurality of electrodes through a

an embodiment of the present invention, a plurality of electrodes are divided into n number of groups, and a touch scan signal is sequentially applied to the n groups.","However, for convenience of a description, the below description will be made on a method where the electrodes are divided into two groups (i.e., n=2).","However, the present invention is not limited to the method where the electrodes are divided into the two groups, and the electrodes may be divided into three or more groups.","FIG.","2 is a diagram illustrating a configuration of a display device with an integrated touch screen according to an embodiment of the present invention.","The display device with the integrated touch screen according to an embodiment of the present invention, as illustrated in FIG.","2, includes: a touch screen 111 that includes m number of electrodes 112 (where m is a multiple of n, and n is an integer more than or equal to two) which are formed to respectively overlap with a plurality of pixel electrodes in a pixel area of a display panel 110; a display driver IC 120 that applies a common voltage Vcom to the electrodes 112 or sequentially applies a touch scan signal to the electrodes of each of two groups 114 into which the m electrodes 112 are divided, according to a driving mode of the panel 110; and a touch IC 130 that generates the touch scan signal and applies the touch scan signal to the display driver IC 120.The touch screen 111 detects a touch point of a user.","Particularly, the touch screen 111 applied to the present embodiment is an in-cell type touch screen using a self-capacitive type, and a touch screen area is the same area as a pixel array area.","The self-capacitive touch screen includes the m electrodes 112 and the same m number of lines 113, in the panel 110.Herein, the panel 110 may be configured in a structure where a liquid crystal layer is formed between two substrates.","In this case, a lower substrate of the panel 110 can include: a plurality of data lines disposed in parallel to each other; a plurality of gate lines that cross the data lines and are disposed in parallel to each other; a plurality of Thin Film Transistors (TFTs) that are respectively formed in a plurality of intersection areas between the data lines and the gate lines; a plurality of pixel electrodes that respectively charge data voltages into the plurality of pixels; an electrode (also referred to as a common electrode) that drives liquid crystal cells injected into the liquid crystal layer, together with the operation of the pixel electrodes.","The pixels are arranged in a matrix type corresponding to the above-described intersection structure between the date lines and the gate lines.","The m electrodes 112 are formed to overlap with the plurality of pixel electrodes, in the pixel array area of the panel 110.For instance, the m electrodes are not formed in each pixel but are formed in an area overlapping with a plurality of pixels.","That is, the m electrodes 112 are preferably disposed over the area where the pixel electrodes are disposed.","The m electrodes 112 may be disposed substantially through the touch screen 111 so that a touch input thereto may be accurately detected.","When the driving mode of the panel 110 is a display driving mode, each of the electrodes 112 operates as a common electrode that drives liquid crystal cells together with the operation of the pixel electrode(s) formed in corresponding pixel(s).","When the driving mode of the panel 110 is a touch driving mode, each electrode 112 operates as a touch electrode that detects a touch point/input by using the touch scan signal applied from the touch IC 130.For example, as illustrated in FIG.","2, the m electrodes 112 may be formed to be divided into two groups 114, and formed in a block type group 114 but the group can be in a different shape.","Each of the groups 114 may be formed in a touch screen 111 area, and the number of electrodes included in each group 114 is m/2.In FIG.","2, the number of electrodes in each of two groups into which the electrodes 112 are divided is m/2, but when the electrodes 112 are divided into n number of groups, the number of electrodes in each of the n groups is m/n, where m and n are positive integers and preferably m is a multiple of n to provide an even division.","The m lines 113 connect the m electrodes 112 to the display driver IC 120, respectively.","Therefore, the common voltage and the touch scan signal that are outputted from the display driver IC 120 are applied to the electrodes 112 through the respective lines 113.When the driving mode of the panel 110 is in the display driving mode, the display driver IC 120 applies the common voltage to the electrodes 112, and when the driving mode of the panel 110 is in the touch driving mode, the display driver IC 120 sequentially applies the touch scan signal to the electrodes of each of the two groups into which the electrodes 112 are divided.","Embodiments of a group division method according to the present invention will be described below in detail.","The display driver IC 120 drives the data lines and gate lines that are formed in the panel 110, and drives each of the m electrodes 112 as a common electrode or a touch electrode.","For this end, the display driver IC 120 may include a common voltage generator 121, a sync signal generator 122, a switching control signal generator 123, and a switching unit 124.The common voltage generator 121 generates a common voltage Vcom and applies the common voltage Vcom to the switching unit 124.Specifically, when the driving mode of the panel 110 is in the display driving mode, the common voltage generator 121 generates the common voltage Vcom which is then applied to the m electrodes 112 for image output, and applies the common voltage Vcom to the switching unit 124.The sync signal generator 122 generates a sync signal indicating the driving mode of the panel 110.For example, as illustrated in FIG.","2, when the driving mode of the panel 110 is in the display driving mode, the sync signal generator 122 generates a first sync signal “0” that allows the common voltage Vcom of the common voltage generator 121 to be applied to the electrodes 112 through the switching unit 124.When the driving mode of the panel 110 is in the touch driving mode, the sync signal generator 122 generates a second sync signal “1” that allows the touch scan signal of the touch IC 130 to be applied to the electrodes 112.The switching control signal generator 123 generates a control signal that allows the electrodes 112 to be simultaneously connected to the common voltage generator 121 or a control signal that allows the electrodes 112 to be sequentially connected to the touch IC 130 for each group, according to the sync signal of the sync signal generator 122.For example, as illustrated in FIG.","2, when the sync signal of the sync signal generator 123 is the first sync signal “0”, the switching control signal generator 123 generates a first control signal “00” that allows the common voltage (received from the common voltage generator 121) to be simultaneously applied to the m electrodes 112.When the sync signal of the sync signal generator 123 is the second sync signal “1”, the switching control signal generator 123 generates a second control signal “01” or “10” that allows the touch scan signal (received from the touch IC 130) to be sequentially applied to the two electrode groups 114.The second control signal may be generated in plurality, according to the number of groups that are connected to the switching unit 124.In other words, in this example, the second control signal denotes two group selection signals (“01” and “10”) that allow the switching unit 124 to be connected to the electrodes 112 by two groups (CH1 and CH2).","However, the electrodes 112 may be divided into two or more groups.","In such cases, when there are n number of groups (n being greater than or equal 2), the second control signal corresponding to n number of group selection signals that are respectively and selectively applied to the n groups is generated.","For instance, if there are 3 electrode groups 114, then the group selection signals of the second control signal may be, e.g., “001”, “010” and “011” which are used to respectively control the three different electrode groups via the channel outputs CH1, CH2 and CH3 of each of the second switching units 126.The switching unit 124 may be configured with a plurality of first switching units 125 and a plurality of second switching units 126.Each of the second switching units 126 includes channels CH1 and CH2.The switching unit 124 operates according to the sync signal of the sync signal generator 122 and the control signal of the switching control signal generator 123.For example, as illustrated in FIG.","2, when the sync signal of the sync signal generator 122 is the first sync signal “0” and the control signal of the switching control signal generator 123 is the first control signal “00”, the common voltage Vcom generated by the common voltage generator 121 is applied to all the electrodes 122.When the sync signal of the sync signal generator 122 is the second sync signal “1” and the control signal of the switching control signal generator 123 is the second control signal “01” or “10”, the touch scan signal generated by the touch IC 130 is applied to the m electrodes 112.More specifically, when the second control signal of the switching control signal generator 123 is the second control signal “01”, the touch scan signal from the touch IC 130 is applied to the electrodes of one of the groups 114 through the channel CH1 of each of the second switching units 126.On the other hand, when the second control signal of the switching control signal generator 123 is the second control signal “10”, the touch scan signal is applied to the electrodes of the other one of the groups 114 through the channel CH2 of each of the second switching units 126.The detailed configurations and operations of the first switching units 125 and second switching units 126 of the switching unit 124 will now be described in detail with reference to FIGS.","2, 3A and 3B according to an embodiment of the present invention.","FIG.","3A is a diagram illustrating a detailed configuration of each of the first and second switching units in FIG.","2.FIG.","3B is a diagram for describing an operation of each of the first and second switching units in FIG.","3A.","The first switching unit 125 may be configured with a 2:1 multiplexer.","For example, as illustrated in FIG.","3A, the first switching unit 125 may be configured with transistors TR1 and TR2.The transistor TR1 may be connected to the common voltage generator 121 and the second switching unit 126, and the transistor TR2 may be connected to the touch IC 130 and the second switching unit 126.Herein, each of the transistors TR1 and TR2 may be a CMOS transistor.","When the sync signal is the first sync signal “0” indicating the display driving mode, the first switching unit 125 connects the common voltage generator 121 to the second switching unit 126.When the sync signal is the second sync signal “1” indicating the touch driving mode, the first switching unit 125 connects the touch IC 130 to the second switching unit 126.For example, when the sync signal of the sync signal generator 122 is the first sync signal “0”, the transistor TR1 of the first switching unit 125 is turned on and simultaneously the transistor TR2 is turned off, and thus, the common voltage generator 121 and the second switching unit 126 are connected to each other through the transistor TR1 of the first switching unit 125, whereupon the common voltage Vcom generated by the common voltage generator 121 is delivered to the second switching unit 126.When the sync signal of the sync signal generator 122 is the second sync signal “1”, the transistor TR2 of the first switching unit 125 is turned on and simultaneously the transistor TR1 is turned off, and thus, the touch IC 130 and the second switching unit 126 are connected to each other through the transistor TR2 of the first switching unit 125, whereupon the touch scan signal generated by the touch IC 130 is delivered to the second switching unit 126.The second switching unit 126 is a signal selector that has one input channel and a plurality of output channels CH1 and CH2.The second switching unit 126 simultaneously or sequentially outputs a signal, supplied from the first switching unit 125, through the output channels CH1 and CH2.For example, as illustrated in FIG.","3A, the second switching unit 126 may be configured with transistors TR3 and TR4, which are connected to the first switching unit 125 and corresponding electrodes 112 through the lines 113.Herein, each of the transistors TR3 and TR4 may be a CMOS transistor.","The second switching unit 126 is connected only to the first switching unit 125 and one electrode for each group.","When the control signal applied to the second switching unit 126 is the first control signal conforming to the first sync signal (display mode), the second switching unit 126 connects the first switching unit 125 to all the electrodes 112.When the control signal is the second control signal conforming to the second sync signal (touch mode), the second switching unit 126 sequentially connects the first switching unit 125 to a plurality of electrodes for each group 114.For example, when the control signal of the switching control signal generator 123 is the first control signal “00” conforming to the first sync signal “0” of the sync signal generator 122, the transistors TR3 and TR4 of the second switching unit 126 are simultaneously turned on, and thus, the first switching unit 125 and all the electrodes 112 are connected to each other through the channels CH1 and CH2 of the respective transistors TR3 and TR4 in the second switching unit 126, whereupon the common voltage Vcom delivered from the first switching unit 125 is applied to all the electrodes 112 including both groups 114 simultaneously.","When the control signal of the switching control signal generator 123 is the second control signal “01” conforming to the second sync signal “1” of the sync signal generator 122, the transistor TR3 of the second switching unit 126 is turned on and simultaneously the transistor TR4 is turned off, and thus, the first switching unit 125 and the electrodes of any one of the groups 114 are connected to each other through the channel CH1 of the transistor TR3 of the second switching unit 126, whereupon the touch scan signal delivered from the first switching unit 125 is applied to all the electrodes of that one group among the groups 114.When the control signal of the switching control signal generator 123 is the second control signal “10” conforming to the second sync signal “1” of the sync signal generator 122, the transistor TR4 of the second switching unit 126 is turned on and simultaneously the transistor TR3 is turned off, and thus, the first switching unit 125 and the electrodes of the other of the groups 114 are connected to each other through the channel CH2 of the transistor TR4 of the second switching unit 126, whereupon the touch scan signal delivered from the first switching unit 125 is applied to all the electrodes of the other group among the groups 114.Referring again to FIG.","2, the touch IC 130 applies the touch scan signal to the electrodes 112 through display driver IC 120, and then detects the change in the capacitance of each electrode to determine whether an electrode area is touched.","The touch IC 130 and the display driver IC 120 are connected to each other through the touch IC channels, and the total number of touch IC channels is m/2.That is, in the related art, the number of electrodes or lines is equal to the number of touch IC channels, but in the present invention, the number of touch IC channels decreases to a half of the number of electrodes 112 or lines 113, which reduces the manufacturing cost and structure configuration.","Hereinafter, an electrode division method will now be described in detail with reference to FIGS.","4 to 8 according to an embodiment of the present invention.","These methods can be implemented using the devices of FIGS.","1-3 or other suitable display devices.","FIG.","4 is a diagram showing a first example of an electrode division method in a display device with an integrated touch screen according to an embodiment of the present invention.","As illustrated in FIG.","4, 160 electrodes can be divided into two groups, namely, an odd group and an even group.","The odd group is connected to the respective channels CH1 of the second switching units 126 in the display driver IC 120, and the even group is connected to the respective channels CH2 of the second switching units 126.When the sync signal generator 122 generates the second sync signal “1” indicating the touch driving mode and the switching control signal generator 123 generates the second control signal “01” designating the channel CH1, the respective channels CH1 of the second switching units 126 are connected to the electrodes of the odd group.","That is, all the channels CH1 of each of the second switching units 126 are connected to the corresponding electrodes of the odd group.","When the sync signal generator 122 generates the second sync signal “1” indicating the touch driving mode and the switching control signal generator 123 generates the second control signal “10” designating the channel CH2, the respective channels CH2 of the second switching units 126 are connected to the electrodes of the even group.","Thus in the example of FIG.","4, the electrodes 112 may be divided into groups having specific configurations.","FIGS.","5A to 5D are diagrams respectively showing experiment data of touch sensitivity detected according to the method of FIG.","4.In the present experiment data, the X axis indicates time, and the y axis indicates raw count.","A raw count value is a value that becomes fundamental for measuring touch sensing, and is to represent a touch sensing signal as a touch clock count value.","A touch driving pulse is applied selectively to the odd group and even group of electrodes shown in FIG.","4.Since the electrodes immediately neighboring the electrode numbers 39 and 40 belong to the same even group, when the touch driving pulse is applied to such electrodes, a high touch sensitivity is provided.","On the other hand, since some electrodes immediately neighboring the electrode numbers 51 and 66 belong to different electrode groups (i.e., the odd group), the neighboring electrodes are grounded when the touch driving pulse is applied to the electrodes 51 and 66.As a result, the touch sensitivity in such area is lower than the touch sensitivity around the electrode numbers 39 and 40.This can be seen in FIGS.","5A and 5B.","Referring to the experiment data, a raw count difference of the electrode number 39 (highlighted in FIG.","4) is 200, a raw count difference of the electrode number 40 is 230, a raw count difference of the electrode number 51 is 100, and a raw count difference of the electrode number 66 is 160.A large raw count difference denotes that the touch sensitivity is better in proportion thereto.","In the present experiment data, there are no electrodes (which are connected to different channels of the second switching unit 126) respectively adjacent to the electrode number 39 and the electrode number 40, and thus, the raw count difference of each of the electrode number 39 and electrode number 40 is greater than that of each of the electrode number 51 and electrode number 66, which means that the touch sensitivity in the area of the electrode numbers 39 and 40 is better than the touch sensitivity in the area of the electrode numbers 51 and 66.Thus to enhance the touch sensitivity of the touch panel, it would be desirable to minimize the number of adjacent electrodes that belong to a different group of touch electrodes driven at a different time.","Accordingly, FIGS.","6 and 7 provide examples of dividing or grouping the touch electrodes according to the present invention to maximize the touch sensitivity of the display panel.","FIGS.","6 and 7 illustrate the examples of a group division method that enables the obtainment of high touch sensitivity, based on the experiment data of FIG.","5.As illustrated in FIGS.","6 and 7, a plurality of electrodes may be divided into a plurality of block type groups.","For example, when the pixel area of the panel 110 is rectangular in shape, by dividing the electrodes 112 into a plurality of groups along a short (shorter) side direction to have a rectangular shape, RC delay is reduced between the adjacent electrodes included in different groups, thus increasing the touch sensitivity of the display device.","FIG.","6 is a diagram showing a second example of an electrode division method in the display device with the integrated touch screen according to an embodiment of the present invention.","Referring to FIG.","6, the plurality of electrodes 112 are divided into two block type groups 114 along the direction of the shorter side of the touch screen 111.One (114a) of the groups 114 is connected to the channels CH1 of the second switching units 126 in the display driver IC 120, and the other group 114b is connected to the channels CH2 of the second switching units 126.When the sync signal generator 122 generates the second sync signal “1” indicating the touch driving mode and the switching control signal generator 123 generates the second control signal “01” designating the channel CH1, the respective channels CH1 of the second switching units 126 are connected to all the electrodes of the one group 114a.","When the sync signal generator 122 generates the second sync signal “1” indicating the touch driving mode and the switching control signal generator 123 generates the second control signal “10” designating the channel CH2, the respective channels CH2 of the second switching units 126 are connected to all the electrodes of the other group 114b.","In the present example, when the pixel area of the panel 110 is rectangular in shape, the block type groups 114 may be formed by dividing the electrodes 112 along a short/shorter side direction of the touch screen 111 to have a rectangular shape or the like, and the numbers of electrodes in each of the divided groups may be the same.","As in the present embodiment, by dividing the electrodes into a plurality of groups along a short/shorter side direction of the touch screen 111 to have a rectangular shape or the like, a proximal surface between the groups 114 is minimized and thus, a potential difference between the electrodes 112 connected to the respective channels of the different second switching units 126 is minimized, thereby increasing the touch sensitivity of the panel 110.In the above-described example, the pixel area is the same area as that of the touch screen 111.FIG.","7 is a diagram showing a third example of an electrode division method in the display device with the integrated touch screen according to an embodiment of the present invention.","Referring to FIG.","7, the electrodes 112 are divided into three block type groups 114 (114a, 114b, 114c), and if the pixel area of the panel 110 is rectangular in shape, similarly to the example of FIG.","6, the block type groups 114 may be formed by dividing the electrodes 112 into a plurality of groups along a short/shorter side direction of the touch screen 111 to have a rectangular shape or the like.","In this way, by dividing the electrodes 112 into the plurality of groups 114a, 114b, 114c along the short side direction to have the rectangular or other shape, a proximal surface between the groups 114 is minimized and thus, a potential difference between the electrodes 112 connected to the respective channels of the different second switching units 126 is minimized, thereby increasing the touch sensitivity of the touch screen 111.The detailed description of this example is the same as that of the above-described second example, and thus is not provided.","In the example of FIG.","7, because there exist three groups 114a, 114b and 114c of the electrodes 112, each of the second switching units 126 would have one input and three outputs CH1, CH2 and CH3 which respectively control the three groups 114a, 114b and 114c.","As such, the number of second switching units 126 needed may correspond to m/n.","In this regard, the switching control signal generator 123 is configured to output appropriate control signals so that each of the groups 114a, 114b and 114c is selectively and independently driven by controlling the output selection among the outputs CH1, CH2 and CH3.The configuration of the first switching units 125 would be the same as that shown in FIGS.","2 and 3.Thus, depending on the number of groups of electrodes formed, the corresponding same number of touch channels for each of the second switching units 126 may be used.","According to the present embodiments, a plurality of electrodes have been exemplarily described as being divided into two groups or three groups, but may be divided into four or more groups according to the number of electrodes.","A driving method of the display device with the integrated touch screen having the above-described configuration, according to an embodiment of the present invention, will be described in detail with reference to FIG.","2.When the driving mode of the display device with the integrated touch screen according to an embodiment of the present invention is in the display driving mode, the sync signal generator 122 generates the first sync signal “0” to transfer the first sync signal “0” to the first switching units 125, and the switching control signal generator 123 generates the first control signal “00” to transfer the first control signal “00” to the second switching units 126.The first switching units 125 are switched and connect the common voltage generator 121 to the second switching units 126, according to the first sync signal “0”.","The second switching units 126 are switched and connect the m electrodes to the channels CH1 and CH2, according to the first control signal “00”.","The common voltage generated by the common voltage generator 121 is applied simultaneously to all the m electrodes 112 through the first switching units 125 and the second switching units 126.When the driving mode of the display device is in the touch driving mode, the sync signal generator 122 generates the second sync signal “1” to transfer the second sync signal “1” to the first switching units 125, and the switching control signal generator 123 generates the second control signal “01” or “10” to transfer the second control signal “01” or “10” to the second switching units 126.The first switching units 125 are switched and connect the touch IC 130 to the second switching units 126, according to the second sync signal “1”.","The second switching units 126 are switched and connect one of the two groups 114 to the channels CH1 and CH2, according to the second control signal “01” or “10”.","When the second control signal is “01”, the channels CH1 of the second switching units 126 are connected to the electrodes of one of the two groups 114.When the second control signal is “10”, the channels CH2 of the second switching units 126 are connected to the electrodes (which are not connected to the channels CH1) of the other group among the two groups 114.The touch scan signal generated from the touch IC 130 is applied sequentially to the two groups through the first switching units 125 and the second switching units 126.Some of the advantages associated with the above-described display device with the integrated touch screen according to an embodiment of the present invention will now be provided.","In the present invention, by applying the common voltage or the touch scan signal to the electrodes of each group through the switching unit that is connected to at least two or more electrode groups of the self-capacitive touch screen, the number of touch ICs and the number of touch IC channels can be reduced which in turn reduces the manufacturing cost of the display device.","Furthermore, in the present invention, the common voltage Vcom is applied directly from the display driver IC to the electrodes without being applied to the electrodes through the touch IC, and thus, image quality can be prevented from being degraded.","According to the embodiments of the present invention, the switching unit is connected to at least two or more electrode groups of the self-capacitive touch screen, and the common voltage or the touch scan signal is applied to the electrodes of each group through the switching

invention relates to a display device, and more particularly, to a display device with an integrated touch screen and a driving method thereof.\",\n \"Discussion of the Related Art Touch screens are a type of input device that is included in image display devices such as Liquid Crystal Displays (LCDs), Field Emission Displays (FEDs), Plasma Display Panel (PDPs), Electroluminescent Displays (ELDs), and Electrophoretic Display (EPDs), and allows a user to input predetermined information by applying a pressure (i.e., by pressing or touching) to a touch sensor of a touch screen of the image display device while looking at the image display device.\",\n \"Particularly, the demand of display devices with an integrated in-cell type touch screen, which include a plurality of built-in elements configuring the touch screen for providing slim portable terminals such as smart phones and tablet Personal Computers (PCs), is recently increasing.\",\n \"Hereinafter, a related art display device with an integrated touch screen will be described with reference to FIG.\",\n \"1.FIG.\",\n \"1 is a diagram illustrating a configuration of a related art display device with an integrated touch screen, and more specifically illustrates a configuration of a display device with an integrated self-capacitive touch screen having an in-cell type.\",\n \"The related art display device with the integrated self-capacitive touch screen having an in-cell type, as illustrated in FIG.\",\n \"1, includes: a panel 10 with a built-in touch screen 11; a display driver IC (DD-IC) 20 that is connected to an external system and controls a plurality of gate lines and data lines in the panel 10; a plurality of touch ICs (T-IC1 and T-IC2) 31 and 32 that drive the touch screen 11 in the panel 10.The panel 10 includes m number of electrodes 12, and m number of lines 13 that are respectively extended from the m electrodes 12.Each of the touch ICs 31 and 32 includes m number of touch IC channels respectively corresponding to the m lines 13, for self-capacitive touch sensing.\",\n \"Since one touch IC channel generally corresponds a line connected to an electrode in one-to-one correspondence relationship, as illustrated in FIG.\",\n \"1, when the number of lines connected to an electrode is more than the number of channels that are capable of being accommodated by one touch IC, a plurality of touch ICs are required to be used, causing the increase in cost.\",\n \"In the display device with the integrated touch screen of FIG.\",\n \"1, each of the electrodes 12 is built in the panel 10 and performs a touch function and a display function, and thus is used as a common electrode for display driving when the display device is driven in a display driving mode, or is used as a touch electrode when the display device is driven in a touch driving mode.\",\n \"The display driving mode is a display mode for displaying images on the display device, and the touch driving mode is a touch mode for detecting and processing a touch input to the display device.\",\n \"On the contrary, when the display device is driven in the display driving mode, a common voltage Vcom outputted from inside the display driver IC (DD-IC) 20 is applied to the electrodes 12 through the touch ICs 31 and 32, in which case the touch ICs 31 and 32 need to accommodate a negative voltage when the common voltage Vcom is the negative voltage.\",\n \"However, the related art touch ICs 31 and 32 cannot accommodate a negative voltage and thus, a special manufacturing process and design for a touch IC that can accommodate the negative voltage are needed, which in turn increases the manufacturing cost of the touch ICs.\",\n \"Moreover, when the related art touch sensitive display device is driven in the display driving mode, a ground-level voltage instead of a negative voltage may be incidentally supplied to the electrode 12 through the touch IC, thereby causing the degradation of image quality.\",\n \"To provide a summary on the above-described limitations, the related art display device with the integrated touch screen has at least the following limitations.\",\n \"First, as the number of touch IC channels matching the respective lines connected to electrodes increases, the number of touch ICs increases, thereby causing the increase in cost for the display device.\",\n \"Second, a touch IC is separately manufactured by modifying the manufacturing process and design thereof for applying a negative common voltage, thereby causing the increase in the manufacturing cost of the touch IC.\",\n \"Third, when the related art touch IC is applied to a display device, the ground-level common voltage, instead of the desired negative common voltage, may be incidentally applied to the electrodes in the display driving mode, thereby causing the degradation of image quality.\",\n \"SUMMARY Accordingly, the present invention is directed to provide a display device with

invention.\",\n \"The display device with the integrated touch screen according to an embodiment of the present invention, as illustrated in FIG.\",\n \"2, includes: a touch screen 111 that includes m number of electrodes 112 (where m is a multiple of n, and n is an integer more than or equal to two) which are formed to respectively overlap with a plurality of pixel electrodes in a pixel area of a

the m electrodes 112 are divided, according to a driving mode of the panel 110; and a touch IC 130 that generates the touch scan signal and applies the touch scan signal to the display driver IC 120.The touch screen 111 detects a touch point of a user.\",\n \"Particularly, the touch screen 111 applied to the present embodiment is an in-cell type touch screen using a self-capacitive type, and a touch screen area is the same area as a pixel array area.\",\n \"The self-capacitive touch screen includes the m electrodes 112 and the same m number of lines 113, in the panel 110.Herein, the panel 110 may be configured in a structure where a liquid crystal layer is formed between two substrates.\",\n \"In this case, a lower substrate of the panel 110 can include: a plurality of data lines disposed in parallel to each other; a plurality of gate lines that cross the data lines and are disposed in parallel to each other; a plurality of Thin Film Transistors (TFTs) that are respectively

cells together with the operation of the pixel electrode(s) formed in corresponding pixel(s).\",\n \"When the driving mode of the panel 110 is a touch driving mode, each electrode 112 operates as a touch electrode that detects a touch point/input by using the touch scan signal applied from the touch IC 130.For example, as illustrated in FIG.\",\n \"2, the m electrodes 112 may be formed to be divided into two groups 114, and formed in a block type group 114 but the group can be in a different shape.\",\n \"Each of the groups 114 may be formed in a touch screen 111 area, and the number of

groups into which the electrodes 112 are divided.\",\n \"Embodiments of a group division method according to the present invention will be described below in detail.\",\n \"The display driver IC 120 drives the data lines and gate lines that are formed in the panel 110, and drives each of the m electrodes 112 as a common electrode or a touch electrode.\",\n \"For this end, the display driver IC 120 may include a common voltage generator 121, a sync signal generator 122, a switching control signal generator 123, and a switching unit 124.The common voltage generator 121 generates a common voltage Vcom and applies the common voltage Vcom to the switching unit 124.Specifically, when the driving mode of the panel 110 is in the display driving mode, the common voltage generator 121 generates the common voltage Vcom which is then applied to the m electrodes 112 for image output, and applies the common voltage Vcom to the switching unit 124.The sync signal generator 122 generates a sync signal indicating the driving mode of the panel 110.For example, as illustrated in FIG.\",\n \"2, when the driving mode of the panel 110 is in the display driving mode, the sync signal generator 122 generates a first sync signal “0” that allows the common voltage Vcom of the common voltage generator 121 to be applied to the electrodes 112 through the switching unit 124.When the driving mode of the panel 110 is in the touch driving mode, the sync signal generator 122 generates a second sync signal “1” that allows the touch scan signal of the touch IC 130 to be applied to the electrodes 112.The switching control signal generator 123 generates a control signal that allows the electrodes 112 to be simultaneously connected to the common voltage generator 121 or a control signal that allows the electrodes 112 to be sequentially connected to the touch IC 130 for each group, according to the sync signal of the sync signal generator 122.For example, as illustrated in FIG.\",\n \"2, when the sync signal of the sync signal generator 123 is the first sync signal “0”, the switching control signal generator 123 generates a first control signal “00” that allows the common voltage (received from the common voltage generator 121) to be simultaneously applied to the m electrodes 112.When the sync signal of the sync signal generator 123 is the second sync signal “1”, the switching control signal generator 123 generates a second control signal “01” or “10” that allows the touch scan signal (received from the touch IC 130) to be sequentially applied to the two electrode groups 114.The second control signal may be generated in plurality, according to the number of groups that are connected to the switching unit 124.In other words, in this example, the second control signal denotes two group selection signals (“01” and “10”) that allow the switching unit 124 to be connected to the electrodes 112 by two groups (CH1 and CH2).\",\n \"However, the electrodes 112 may be divided into two or more groups.\",\n \"In such cases, when there are n number of groups (n being greater than or equal 2), the second control signal corresponding to n number of group selection signals that are respectively and selectively applied to the n groups is generated.\",\n \"For instance, if there are 3 electrode groups 114, then the group selection signals of the second control signal may be, e.g., “001”, “010” and “011” which are used to respectively control the three different electrode groups via the channel outputs CH1, CH2 and CH3 of each of the second switching units 126.The switching unit 124 may be configured with a plurality of first switching units 125 and a plurality of second switching units 126.Each of the second switching units 126 includes channels CH1 and CH2.The switching unit 124 operates according to the sync signal of the sync signal generator 122 and the control signal of the switching control signal generator 123.For example, as illustrated in FIG.\",\n \"2, when the sync signal of the sync signal generator 122 is the first sync signal “0” and the control signal of the switching control signal generator 123 is the first control signal “00”, the common voltage Vcom generated by the common voltage generator 121 is applied to all the electrodes 122.When the sync signal of the sync signal generator 122 is the second sync signal “1” and the control signal of the switching control signal generator 123 is the second control signal “01” or “10”, the touch scan signal generated by the touch IC 130 is applied to the m electrodes 112.More specifically, when the second control signal of the switching control signal generator 123 is the second control signal “01”, the touch scan signal from the touch IC 130 is applied to the electrodes of one of the groups 114 through the channel CH1 of each of the second switching units 126.On the other hand, when the second control signal of the switching control signal generator 123 is the second control signal “10”, the touch scan signal is applied to the electrodes of the other one of the groups 114 through the channel CH2 of each of the second switching units 126.The detailed configurations and operations of the first switching units 125 and second switching units 126 of the switching unit 124 will now be described in detail with reference to FIGS.\",\n \"2, 3A

unit 126.When the sync signal is the second sync signal “1” indicating the touch driving mode, the first switching unit 125 connects the touch IC 130 to the second switching unit 126.For example, when the sync signal of the sync signal generator 122 is the first sync signal “0”, the transistor TR1 of the first switching unit 125 is turned on and simultaneously the transistor TR2 is turned off, and thus, the common voltage generator 121 and the second switching unit 126 are connected to each other through the transistor TR1 of the first switching unit 125, whereupon the common voltage Vcom generated by the common voltage generator 121 is delivered to the second switching unit 126.When the sync signal of the sync signal generator 122 is the second sync signal “1”, the transistor TR2 of the first switching unit 125 is turned on and simultaneously the transistor TR1 is turned off, and thus, the touch IC 130 and the second switching unit 126 are connected to each other through the transistor TR2 of the first switching unit 125, whereupon the touch scan signal generated by the touch IC 130 is delivered to the second switching unit 126.The second switching unit 126 is a signal selector that has one input channel and a plurality of output channels CH1 and CH2.The second switching unit 126 simultaneously or sequentially outputs a signal, supplied from the first switching unit

signal (touch mode), the second switching unit 126 sequentially connects the first switching unit 125 to a plurality of electrodes for each group 114.For example, when the control signal of the switching control signal generator 123 is the first control signal “00” conforming to the first sync signal “0” of the sync signal generator 122, the transistors TR3 and TR4 of the second switching unit 126 are simultaneously turned on, and thus, the first switching unit 125 and all the electrodes 112 are connected to each other through the channels CH1 and CH2 of the respective transistors TR3 and TR4 in the second switching unit 126, whereupon the common voltage Vcom delivered from the first switching unit 125 is applied to all the electrodes 112 including both groups 114 simultaneously.\",\n \"When the control signal of the switching control signal generator 123 is the second control signal “01” conforming to the second sync signal “1” of the sync signal generator 122, the transistor TR3 of the second switching unit 126 is turned on and simultaneously the transistor TR4 is turned off, and thus, the first switching unit 125 and the electrodes of any one of the groups 114 are connected to each other through the channel CH1 of the transistor TR3 of the second switching unit 126, whereupon the touch scan signal delivered from the first switching unit 125 is

into groups having specific configurations.\",\n \"FIGS.\",\n \"5A to 5D are diagrams respectively showing experiment data of touch sensitivity detected according to the method of FIG.\",\n \"4.In the present experiment data, the X axis indicates time, and the y axis indicates raw count.\",\n \"A raw count value is a value that becomes fundamental for measuring touch sensing, and is to represent a touch sensing signal as a touch clock count value.\",\n \"A touch driving pulse is applied selectively to the odd group and even group of electrodes shown in FIG.\",\n \"4.Since the electrodes immediately neighboring the electrode numbers 39 and 40 belong to the same even group, when the touch driving pulse is applied to such electrodes, a high touch sensitivity is provided.\",\n \"On the other hand, since some electrodes immediately neighboring the electrode numbers 51 and 66 belong to different electrode groups (i.e., the odd group), the neighboring electrodes are grounded when the touch driving pulse is applied to the electrodes 51 and 66.As a result, the touch sensitivity in such area is lower than the touch sensitivity around the electrode numbers 39 and 40.This can be seen in FIGS.\",\n \"5A and 5B.\",\n \"Referring to the experiment data, a raw count difference of the electrode number 39 (highlighted in FIG.\",\n \"4) is 200, a raw count difference of the electrode number 40 is 230, a raw count difference of the electrode number 51 is 100, and a raw count difference of the electrode number 66 is 160.A large raw count difference denotes that the touch sensitivity is better in proportion thereto.\",\n \"In the present experiment data, there are no electrodes (which are connected to different channels of the second switching unit 126) respectively adjacent to the electrode number 39 and the electrode number 40, and thus, the raw count difference of each of the electrode number 39 and electrode number 40 is greater than that of each of the electrode number 51 and electrode number 66, which means that the touch sensitivity in the area of the electrode numbers 39 and 40 is better than the touch sensitivity in the area of the electrode numbers 51 and 66.Thus to enhance the touch sensitivity of the touch panel, it would be desirable to minimize the number of adjacent electrodes that belong to a different group of touch electrodes driven at a different time.\",\n \"Accordingly, FIGS.\",\n \"6 and 7 provide examples of dividing or grouping the touch electrodes according to the present invention to maximize the touch sensitivity of the

operating conditions on a valve assembly.","Unlike previous techniques, which for the most part only detect or establish the “presence” of the operating condition, the embodiments herein can readily identify what is causing the operating condition to occur on the valve assembly.","This information can enlighten the process owner/operator to better address the operating condition, effectively saving time and money by avoiding unnecessary repairs to valve assemblies that would not otherwise require maintenance.","FIG.","1 depicts a flow diagram of an exemplary embodiment of a method 100 for use on and/or as part of a valve assembly and a process control system.","This diagram outlines steps that may embody instructions for one or more computer-implemented methods and/or programs.","In FIG.","1, the embodiment includes, at step 102, receiving an input with a sample set of data, the sample set comprising data samples collected and/or gathered from, e.g., the valve assembly.","The embodiment also includes, at step 104, determining a first amplitude for the operating parameters and, at step 106, comparing the first amplitude to a second amplitude for the operating parameters.","In one implementation, the embodiment can include, at step 108, generating an output that relates to a position of the first amplitude relative to the second amplitude, namely, a relative position of the first amplitude with respect to the second amplitude.","As discussed more below, in one example the first amplitude has a value that quantifies an amount of stick-slip on the valve assembly.","Broadly, the method 100 can configure the valve assembly and/or the process control system, generally, to process data in a way that associates characteristics of operation of the valve assembly with a root cause and/or a contributing factor.","The data samples may correspond with operating parameters, for example, values for position, setpoint, and pressure for the valve assembly.","These values are readily available and stored as part of normal operation and control of the valve assembly.","In use, the method 100 can assign the first amplitude with a value that quantifies movement or “jump” of the valve stem that results from stick-slip on the valve assembly.","This movement typically occurs between a first position and a second position.","The method 100 can assign the second amplitude with a value that quantifies a change in the data for the setpoint and/or the position, for example, as between a first setpoint and a second setpoint.","As noted above, the method 100 can ascertain the relationship or “relative position” of the first amplitude relative to the second amplitude, or vice versa.","This relative position may convey that the first amplitude is greater than the second amplitude, that the first amplitude is less than the second amplitude, and/or that the first amplitude is the same as (also equal to) the second amplitude.","Notably, the present disclosure contemplates that the method 100 can use the relationship between the first amplitude and the second amplitude to indicate the root cause of the operation of the valve assembly.","This relationship may, for example, indicate that stick slip is the root cause of repeated up-and-down travel of the valve stem (also, “valve stem cycling” and/or “valve cycling”).","On the other hand, the relationship may indicate that abnormal or “out-of-control” process conditions on the process line are the root cause of the valve stem cycling.","Such process conditions often prompt the process control system to issue the command signal in a manner that is the root cause of the valve stem cycling.","The method 100 can tailor the output to provide an alert or like indicator that instructs as to the root cause.","This indicator can focus the response of an end user (e.g., process owner/operator) on the problem, e.g., to avoid unnecessary repairs to the valve assembly in the event that the root cause relates to abnormal process conditions.","FIGS.","2 and 3 depict plots of data for operating parameters of a valve assembly.","The data reflects position POS, setpoint SP, and actuator pressure P (FIG.","2), each collected over a time scale T. In each of the plots, the valve assembly exhibits cycling of the position POS.","The plot of FIG.","2 indicates operation of the valve assembly under stick-slip conditions.","On the other hand, the plot of FIG.","3 indicates operation of the valve assembly that shows signs of stick-slip (as identified, generally, by SLIP), but otherwise is cycling in response to abnormal conditions on the process line.","The embodiments herein can process the data in each of FIGS.","2 and 3 to identify the root cause of operation.","These embodiments can, in one example, discern stick-slip cycling that corresponds with the distinctive pattern of the position POS data in the plot of FIG.","2.This pattern has abrupt changes, or jumps, that have an amplitude that is sufficient to indicate the build-up of pressure and overshoot that occurs due to the inherent friction in the valve stem/packing interface.","The embodiments can also discern that process cycling is the root cause of the pattern of position POS data in the plot of FIG.","3.In this example, while the position POS data shows some areas of stick-slip (e.g., areas SLIP), the amplitude of the jump in the position POS data is not sufficient to associate the cycling issues with stick-slip.","Rather, the pattern of the position POS data overwhelmingly follows the cycling of the setpoint SP, which may occur in response to process-related issues.","FIG.","4 depicts a flow diagram for an exemplary embodiment of a method 200 that can use the stick-slip amplitude to arrive at the root cause and/or contributing factors of valve stem cycling.","The method 200 includes, at step 210, identifying a cycling condition on the valve assembly, which can instruct the method 200 (to return to step 202) to continue to process data until such condition exists on the valve assembly.","The method 200 also includes, at step 212, determining an amplitude of one or more of the operating parameters that exhibit the cycling condition.","The method 200 further includes, at step 214, identifying a stick-slip condition on the valve assembly and/or whether a stick-slip condition is present on the valve assembly.","If the stick slip condition is not present, then the method 200 continues, at step 216, comparing an amplitude for a first operating parameter (A1) to an amplitude for a second operating parameter (A2).","On the other hand, if the stick slip condition is present, then the method 200 continues, at step 204, determining a stick-slip amplitude (as noted, for example, in the method 300 below) and, at step 206, comparing the stick-slip amplitude to the amplitude of the first operating parameter and/or the amplitude for the second operating parameter.","The generated output (e.g., at step 208) can reflect the relative position of the stick-slip amplitude, the amplitude of the first operating parameter, and the amplitude of the second operating parameter, as compared to one another in context of the steps outlined above and in Table 1 below.","TABLE 1 Stick-Slip Relative Contributing Example Present Position Factor 1 No A1 > F1 × A2 Positioner Tuning 2 No A1 < F2 × A2 Process Control 3 Yes A2 > F3 × AST Process Control 4 Yes A2 < F4 × AST Stick-Slip As noted above, the method 200 is configured to identify one or more contributing factors that cause cycling on the valve assembly.","In Table 1, the amplitudes A1, A2, and AST correspond with, respectively, the amplitude of position POS (FIGS.","2 and 3), the amplitude of setpoint SP (FIGS.","2 and 3), and the stick-slip amplitude of position POS (FIGS.","2 and 3).","The configurations of the method 200 may employ one or more factors, noted in the example of Table 1 above as a first factor F1, a second factor F2, a third factor F3, and a fourth factor F4.Values for the factors F1, F2, F3, and F4 can vary as to their effect within the processing of the data, as desired.","In one implementation, the factors serve to increase and/or decrease the relative value of the amplitude A2 and/or AST, e.g., by a factor of 2, 4, 6, etc.","In one example, the stick-slip amplitude is calculated in accordance with the steps outlined in the method 300 below (FIG.","5).","The steps of determining whether the stick-slip condition is present (e.g., at step 214) also analyze the data for the position POS and the setpoint SP.","These steps may include, for example, determining a stick-slip condition metric, an example of which is noted in Equation (1) below, M ST = M P M S , Equation ( 1 ) in which MST is the stick-slip condition metric, MP is a position metric, and MS is a setpoint metric.","The method 300 can include steps for comparing the stick-slip condition metric MST to a threshold criteria, which may identify a value for the ratio of the position metric MP to the setpoint metric MS that corresponds with and/or relates to stick-slip on the valve assembly.","Examples of the value for the threshold criteria may be in a range from about 1 to about 3.In one implementation, if the stick-slip condition metric MST does not satisfy (e.g., is greater than, less than, and/or equal to) this threshold criteria, then the stick-slip condition is not present on the valve assembly.","The output can convey that stick-slip is present and/or not present on the valve assembly.","In one example, the value for the first amplitude corresponds with the stick-slip condition metric being less than or equal to the value for the threshold criteria.","The method 300 can also include steps for calculating the position metric and/or the setpoint metric using “p-norm” functions, as set forth in Equations (2) and (3) below, M P = ∑ ( P i - P i - 1 ) X N X , Equation ( 2 ) M S = ∑ ( S i - S i - 1 ) X N X , Equation ( 3 ) in which Pi-1 is a first data sample for the position, Pi is a second data sample for the position that is adjacent the first data sample in the sample set, Si-1 is a first data sample for the setpoint, Si is a second data sample for the setpoint that is adjacent the first data sample in the sample set, N is a number of data samples in the sample set, and X is a p-norm parameter.","Examples of the p-norm parameter can be in a range of from about 2 to about 6, but this disclosure does contemplate certain configurations of the methods herein in which the p-norm parameter falls outside of this range.","FIG.","5 illustrates a flow diagram of an exemplary embodiment of a method 300 that includes exemplary steps to arrive at values that quantify the amplitude of the “jump” shown in position (e.g., position POS of FIGS.","2 and 3).","This amplitude is also referred to herein (e.g., in FIG.","4 above) as the stick-slip amplitude.","These steps process the data samples in the data set; in one example, this process starts with the second data sample in the data set and ends with the last data sample in the data set.","In FIG.","5, the method 300 includes, at step 302, receiving an input with the sample set of data and, at step 304, selecting a data sample from the data set.","The method 300 also includes, at step 306, determining a first sample interval and, at step 308, comparing the first sample interval to a first threshold value.","If the first sample interval exceeds the first threshold value, then the method 300 can include, at step 310, incrementing a cycle variable and, at step 312, determining a total interval value.","In one embodiment, the method 300 includes, at step 314, determining whether the last data sample has been processed and, if so, then the method 300 can include, at step 316, calculating the first amplitude (e.g., the stick-slip amplitude (AST)) using the values for the total interval value and/or the count variable.","This disclosure contemplates implementation of the method 300 as an iterative process to process a plurality of data samples.","In this connection, the method 300 can include steps for calculating one or more sample intervals, for example, one that occurs between data samples that are adjacent to one another in the sample set of data.","The steps can also include steps for comparing each of the sample intervals to the first threshold value that relates to the position.","Examples of the total interval value may be calculated by steps for adding together (and/or summing and/or aggregating) the one or more sample intervals to arrive at the total interval value.","In one example, the total interval value may only include the one or more sample intervals that satisfy (also, where applicable, deviate from) the first threshold value for the data samples in the data set.","This criteria may indicate that the one or more sample intervals are each greater than, less than, and/or equal to the first threshold value, as desired.","In another example, the steps may include steps for incrementing the cycle variable for each of the one or more sample intervals that exceed the first threshold value.","The steps may also arrive at the value for the first amplitude by incorporating one or both of the cycle variable and the total interval value, for example, where the value for the first amplitude is equal to the ratio of the total interval value to the cycle count.","The method 300 can include steps that provide a value for the first sample interval as positive and/or non-negative (and/or greater than or equal to zero).","This feature is useful to calculate the amplitude of the “jump” independent of the direction of movement of the valve stem—i.e., in both the positive direction and the negative direction.","In one embodiment, the method 300 may include steps to calculate the first sample interval in accordance with Equation (4) below, I=|P2−P1|, Equation (4) in which I is a first sample interval among the one or more sample intervals, P1 is a previously-stored data sample, and P2 is a data sample that is adjacent the previously-stored data sample P1 in the sample set of data.","The method 300 can also include steps to generate a value for the first threshold value that, like the value for the first sample interval, is also positive and/or non-negative.","This value may reflect use of a “p-norm” function.","In one embodiment, the method 300 may include steps to calculate the first threshold value in accordance with Equation (5) below, RMP position = ∑ ( P i - P i - 1 ) X N X , Equation ( 5 ) in which RMPPosition is the first threshold value, Pi-1 is a first data sample for the position in the sample set, Pi is a second data sample for the position that is adjacent the first data sample in the sample set, N is a number of data samples in the sample set, and X is a p-norm parameter.","Examples of the p-norm parameter can be in a range of from about 2 to about 6, but this disclosure does contemplate certain configurations of the methods herein in which the p-norm parameters falls outside of this range.","FIG.","6 depicts a flow diagram of an exemplary embodiment of a method 400 with exemplary steps to determine a value for the position amplitude and the setpoint amplitude.","The method 400 includes, at step 402, receiving an input with the sample set of data and, at step 404, selecting a first data sample (also “starting data sample”), for example, the first data sample among the data samples in the data set.","The method 400 also includes, at step 406, identifying the starting data sample as a first vertex in the data set and, at step 408, comparing a first deviation with a second threshold value.","The first deviation measures the difference between the value of the starting data sample and the value of other data samples in the data set.","Notably, in one implementation, if no deviation is found in excess of the second threshold value, then the valve assembly is considered to be operating normally—i.e., the valve assembly is not cycling.","On the other hand, if the first deviation is found in excess of the second threshold value, then the method 400 continues to include, at step 410, determining a direction of travel for the valve stem.","The direction of travel is, typically, positive (or “increasing”) for situations in which the value of the first vertex is greater than the value of the starting data sample or negative (or “decreasing”) for situations in which the value of the first vertex is less than the value of the starting data sample.","The direction of travel can influence further processing of the data samples.","As also shown in FIG.","6, the method 400 can include, at step 412, selecting a second data sample from the data set, often starting with a data sample that is adjacent or consecutive with the first vertex and ending with the last data sample in the data set.","When the direction of travel is “increasing,” the method 400 continues, at step 414, comparing the selected data sample to the first vertex.","If the selected data sample is greater than the first vertex, then the method 400 includes, at step 416, storing the selected data sample as the first vertex and continues back to step 412 to select a different data sample.","If the selected data sample is less than the first vertex, then the method 400 can include, at step 418, comparing a second deviation between the selected data sample and the first vertex to the second threshold value.","If the second deviation is less than the second threshold value, then the method continues to include, at step 420, incrementing a vertex count that identifies each occurrence of a vertex in the sample set of data, at step 422, identifying the selected data sample as the second vertex, and, at step 424, changing the direction of travel to decreasing.","In one example, the vertex corresponds with a data sample from the sample set of data that has a relative position with respect to a previously-stored data sample from the sample set of data that exceeds the second threshold value.","The method 400 can continue, at step 426, determining whether the selected data sample is the last data sample in the data set.","If the selected data sample is the last data sample in the data set, then the method 400 can continue to include, at step 428 and/or step 430, determining a cycle count and/or a cycle amplitude, as set forth herein.","In one embodiment, the cycle amplitude corresponds with the second amplitude, which in turn may correspond with an average of the relative positions from one vertex to another vertex for the sample set of data.","Thus, the method 400 may include one or more steps for storing each of the deviations (e.g., the second deviation) between the adjacent data samples.","When the direction of travel is “decreasing,” then the method 400 continues, at step 414, comparing the selected data sample to the first vertex.","If the selected data sample is less than the first vertex, then the method 400 includes, at step 416, storing the selected data sample as the first vertex and continues back to step 412 to select a different data sample.","If the selected data sample is greater than the first vertex, the method 400 can include, at step 418, comparing the second deviation between the selected data sample and the first vertex to the second threshold.","If the second deviation is greater than the second threshold value, then the method continues to include, at step 420, incrementing

assembly.\",\n \"Stick-slip describes a condition, for example, that results from high static friction and/or low kinetic friction between the valve stem and the valve packing material that surrounds the valve stem.\",\n \"This configuration can prevent leaks from inside the valve assembly.\",\n \"During operation, however, stick-slip can cause internal force, i.e., pressure on the closure member, to exceed normal operating levels in order to overcome the static friction that prevents movement of the valve stem.\",\n \"These internal forces, while desirable to induce movement of the valve stem, can cause the valve stem to overshoot its desired position.\",\n \"The process control system will attempt to correct this error.\",\n \"In response to overshoot, for example, the process control system often issues instructions for the valve assembly to modulate the valve stem in the opposite direction.\",\n \"However, it is likely that stick-slip will disrupt the movement in the opposite direction.\",\n \"The resulting errors will again prompt intervention from the control system to move the valve stem in the other direction.\",\n \"This process repeats itself, resulting in oscillation or cycling of the valve stem that can disrupt the stability of the process line as well as cause unnecessary wear on the valve assembly.\",\n \"BRIEF DESCRIPTION OF THE INVENTION This disclosure describes improvements in valve diagnostics that can more accurately distinguish cycling that is induced by process and tuning issues from cycling that is induced by stick-slip.\",\n \"These improvements embody methods with steps that can quantify the amplitude of movement of the valve stem because of stick-slip.\",\n \"These embodiments compare this stick-slip amplitude to an amplitude of other operating parameters (e.g., setpoint) of the valve assembly.\",\n \"In this way, the embodiments can generate an output that indicates the contributing factor of cycling on the valve assembly.\",\n \"As noted herein, these contributing factors can identify whether cycling occurs due to stick-slip or that cycling occurs in response to a process control, namely, modulation of a control signal by the process control system to regulate process parameters on a process line.\",\n \"BRIEF DESCRIPTION OF THE DRAWINGS Reference is now made briefly to the accompanying drawings, in

for the most part only detect or establish the “presence” of the operating condition, the embodiments herein can readily identify what is causing the operating condition to occur on the valve assembly.\",\n \"This information can enlighten the process owner/operator to better address the operating condition, effectively saving time and money by avoiding unnecessary repairs to valve assemblies that would not otherwise require maintenance.\",\n \"FIG.\",\n \"1 depicts a flow diagram of an exemplary embodiment of a method 100 for use on and/or as part of a valve assembly and a process control system.\",\n \"This diagram outlines steps that may embody instructions for one or more computer-implemented methods and/or programs.\",\n \"In FIG.\",\n \"1, the embodiment includes, at step 102, receiving an input with a sample set of data, the sample set comprising data samples collected and/or gathered from, e.g., the valve assembly.\",\n \"The embodiment also includes, at step 104, determining a first amplitude for the operating parameters and, at step 106, comparing the first amplitude to a second amplitude for the operating parameters.\",\n \"In one implementation, the embodiment can include, at step 108, generating an output that relates to a position of the first amplitude relative to the second amplitude, namely, a relative position of the first amplitude with respect to the second amplitude.\",\n \"As discussed more below, in one example the first amplitude has a value that quantifies an amount of stick-slip on the valve assembly.\",\n \"Broadly, the method 100 can configure the valve assembly and/or the process control system, generally, to process data in a way that associates characteristics of operation of the valve assembly with a root cause and/or a contributing factor.\",\n \"The data samples may correspond with operating parameters, for example, values for position, setpoint, and pressure for the valve assembly.\",\n \"These values are readily available and stored as part of normal operation and control of the valve assembly.\",\n \"In use, the method 100 can assign the first amplitude with a value that quantifies movement or “jump” of the valve stem that results from stick-slip on the valve assembly.\",\n \"This movement typically occurs between a first position and a second position.\",\n \"The method 100 can assign the second amplitude with a value that quantifies a change in the data for the setpoint and/or the position, for example, as between a first setpoint and a second setpoint.\",\n \"As noted above, the method 100 can ascertain the relationship or “relative position” of the first amplitude relative to the second amplitude, or vice versa.\",\n \"This relative position may convey that the first amplitude is greater than the second amplitude, that the first amplitude is less than the second amplitude, and/or that the first amplitude is the same as (also equal to) the second amplitude.\",\n \"Notably, the present disclosure contemplates that the method 100 can use the relationship between the first amplitude and the second amplitude to indicate the root cause of the operation of the valve assembly.\",\n \"This relationship may, for example, indicate that stick slip is the root cause of repeated up-and-down travel of the valve stem (also, “valve stem cycling” and/or “valve cycling”).\",\n \"On the other hand, the relationship may indicate that abnormal or “out-of-control” process conditions on the process line are the root cause of the valve stem cycling.\",\n \"Such process conditions often prompt the process control system to issue the command signal in a manner that is the root cause of the valve stem cycling.\",\n \"The method 100 can tailor the output to provide an alert or like indicator that instructs as to the root cause.\",\n \"This indicator can focus the response of an end user (e.g., process owner/operator) on the problem, e.g., to avoid unnecessary repairs to the valve assembly in the event that the root cause relates to abnormal process conditions.\",\n \"FIGS.\",\n \"2 and 3 depict plots of data for operating parameters of a valve assembly.\",\n \"The data reflects position POS, setpoint SP, and actuator pressure P (FIG.\",\n \"2), each collected over a time scale T. In each of the plots, the valve assembly exhibits cycling of the position POS.\",\n \"The plot of FIG.\",\n \"2 indicates operation of the valve assembly under stick-slip conditions.\",\n \"On the other hand, the plot of FIG.\",\n \"3 indicates operation of the valve assembly that shows signs of stick-slip (as identified, generally, by SLIP), but otherwise is cycling in response to abnormal conditions on the process line.\",\n \"The embodiments herein can process the data in each of FIGS.\",\n \"2 and 3 to identify the root cause of operation.\",\n \"These embodiments can, in one example, discern stick-slip cycling that corresponds with the distinctive pattern of the position POS data in the plot of FIG.\",\n \"2.This pattern has abrupt changes, or jumps, that have an amplitude that is sufficient to indicate the build-up of pressure and overshoot that occurs due to the inherent friction in the valve stem/packing interface.\",\n \"The embodiments can also discern that process cycling is the root cause of the pattern of position POS data in the plot of FIG.\",\n \"3.In this example, while the position POS data shows some areas of stick-slip (e.g., areas SLIP), the amplitude of the jump in the position POS data is not sufficient to associate the cycling issues with stick-slip.\",\n \"Rather, the pattern of the position POS data overwhelmingly follows the cycling of the setpoint SP, which may occur in response to process-related issues.\",\n \"FIG.\",\n \"4 depicts a flow diagram for an exemplary embodiment of a method 200 that can use the stick-slip amplitude to arrive at the root cause and/or contributing factors of valve stem cycling.\",\n \"The method 200 includes, at step 210, identifying a cycling condition on the valve assembly, which can instruct the method 200 (to return to step 202) to continue to process data until such condition exists on the valve assembly.\",\n \"The method 200 also includes, at step 212, determining an amplitude of one or more of the operating parameters that exhibit the cycling condition.\",\n \"The method 200 further includes, at step 214, identifying a stick-slip condition on the valve assembly and/or whether a stick-slip condition is present on the valve assembly.\",\n \"If the stick slip condition is not present, then the method 200 continues, at step 216, comparing an amplitude for a first operating parameter (A1) to an amplitude for a second operating parameter (A2).\",\n \"On the other hand, if the stick slip condition is present, then the method 200 continues, at step 204, determining a stick-slip amplitude (as noted, for example, in the method 300 below) and, at step 206, comparing the stick-slip amplitude to the amplitude of the first operating parameter and/or the amplitude for the second operating parameter.\",\n \"The generated output (e.g., at step 208) can reflect the relative position of the stick-slip amplitude, the amplitude of the first operating parameter, and the amplitude of the second operating parameter, as compared to one another in context of the steps outlined above and in Table 1 below.\",\n \"TABLE 1 Stick-Slip Relative Contributing Example Present Position Factor 1 No A1 > F1 × A2 Positioner Tuning 2 No A1 < F2 × A2 Process Control 3 Yes A2 > F3 × AST Process Control 4 Yes A2 < F4 × AST Stick-Slip As noted above, the method 200 is configured to identify one or more contributing factors that cause cycling on the valve assembly.\",\n \"In Table 1, the amplitudes A1, A2, and AST correspond with, respectively, the amplitude of position POS (FIGS.\",\n \"2 and 3), the amplitude of setpoint SP (FIGS.\",\n \"2 and 3), and the stick-slip amplitude of position POS (FIGS.\",\n \"2 and 3).\",\n \"The configurations of the method 200 may employ one or more factors, noted in the example of Table 1 above as a first factor F1, a second factor F2, a third factor F3, and a fourth factor F4.Values for the factors F1, F2, F3, and F4 can vary as to their effect within the processing of the data, as desired.\",\n \"In one implementation, the factors serve to increase and/or decrease the relative value of the amplitude A2 and/or AST, e.g., by a factor of 2, 4, 6, etc.\",\n \"In one example, the stick-slip amplitude is calculated in accordance with the steps outlined in the method 300 below (FIG.\",\n \"5).\",\n \"The steps of determining whether the stick-slip condition is present (e.g., at step 214) also analyze the data for the position POS and the setpoint SP.\",\n \"These steps may include, for example, determining a stick-slip condition metric, an example of which is noted in Equation (1) below, M ST = M P M S , Equation ( 1 ) in which MST is the stick-slip condition metric, MP is a position metric, and MS is a setpoint metric.\",\n \"The method 300 can include steps for comparing the stick-slip condition metric MST to a threshold criteria, which may identify a value for the ratio of the position metric MP to the setpoint metric MS that corresponds with and/or relates to stick-slip on the valve assembly.\",\n \"Examples of the value for the threshold criteria may be in a range from about 1 to about 3.In one implementation, if the stick-slip condition metric MST does not satisfy (e.g., is greater than, less than, and/or equal to) this threshold criteria, then the stick-slip condition is not present on the valve assembly.\",\n \"The output can convey that stick-slip is present and/or not present on the valve assembly.\",\n \"In one example, the value for the first amplitude corresponds with the stick-slip condition metric being less than or equal to the value for the threshold criteria.\",\n \"The method 300 can also include steps for calculating the position metric and/or the setpoint metric using “p-norm” functions, as set forth in Equations (2) and (3) below, M P = ∑ ( P i - P i - 1 ) X N X , Equation ( 2 ) M S = ∑ ( S i - S i - 1 ) X N X , Equation ( 3 ) in which Pi-1 is a first data sample for the position, Pi is a second data sample for the position that is adjacent the first data sample in the sample set, Si-1 is a first data sample for the setpoint, Si is a second data sample for the setpoint that is adjacent the first data sample in the sample set, N is a number of data samples in the sample set, and X is a p-norm parameter.\",\n \"Examples of the p-norm parameter can be in a range of from about 2 to about 6, but this disclosure does contemplate certain configurations of the methods herein in which the p-norm parameter falls outside of this range.\",\n

(e.g., position POS of FIGS.\",\n \"2 and 3).\",\n \"This amplitude is also referred to herein (e.g., in FIG.\",\n \"4 above) as the stick-slip amplitude.\",\n \"These steps process the data samples

interval and, at step 308, comparing the first sample interval to a first threshold value.\",\n \"If the first sample interval exceeds the first threshold value, then the method 300 can include, at step 310, incrementing a cycle variable and, at step 312, determining a total interval value.\",\n \"In one embodiment, the method 300 includes, at step 314, determining whether the last data sample has been processed and, if so, then the method 300 can include, at step 316, calculating the first amplitude (e.g., the stick-slip amplitude (AST)) using the values for the total interval value and/or the count variable.\",\n \"This disclosure contemplates implementation of the method 300 as an iterative process to process a plurality of data samples.\",\n \"In this connection, the method 300 can include steps for calculating one or more sample intervals, for example, one that occurs between data samples that are adjacent to one another in the sample set of data.\",\n \"The steps can also include steps for comparing each of the sample intervals to the first threshold value that relates to the position.\",\n \"Examples of the total interval value may be calculated by steps for adding together (and/or summing and/or aggregating) the one or more sample intervals to arrive at the total interval value.\",\n \"In one example, the total interval value may only include the one or more sample intervals that satisfy (also, where applicable, deviate from) the first threshold value for the data samples in the data set.\",\n \"This criteria may indicate that the one or more sample intervals are each greater than, less than, and/or equal to the first threshold value, as desired.\",\n \"In another example, the steps may include steps for incrementing the cycle variable for each of the one or more sample intervals that exceed the first threshold value.\",\n \"The steps may also arrive at the value for the first amplitude by incorporating one or both of the cycle variable and the total interval value, for example, where the value for the first amplitude is equal to the ratio of the total interval value to the cycle count.\",\n \"The method 300 can include steps that provide a value for the first sample interval as positive and/or non-negative (and/or greater than or equal to zero).\",\n \"This feature is useful to calculate the amplitude of the “jump” independent of the direction of movement of the valve stem—i.e., in both the positive direction and the negative direction.\",\n \"In one embodiment, the method 300 may include steps to calculate the first sample interval in accordance with Equation (4) below, I=|P2−P1|, Equation (4) in which I is a first sample interval among the one or more sample intervals, P1 is a previously-stored data sample, and P2 is a data sample that is adjacent the previously-stored data sample P1 in the sample set of data.\",\n \"The method 300 can also include steps to generate a value for the first threshold value that, like the value for the first sample interval, is also positive and/or non-negative.\",\n \"This value may reflect use of a “p-norm” function.\",\n \"In one embodiment, the method 300 may include steps to

position amplitude and the setpoint amplitude.\",\n \"The method 400 includes, at step 402, receiving an input with the sample set of data and, at step 404, selecting a first data sample (also

view illustrating a treatment instrument for the endoscope 1 according to this embodiment.","The treatment instrument for the endoscope 1 is equipped with a sheath 2, a balloon 3, a connecting section 4, a distal end tip 5, and a stylet 6.The sheath 2 is a member which has a lumen 21, is long in a direction of a longitudinal axis L, and has flexibility.","A proximal end portion of the balloon 3 is tightly connected to the distal end portion of the sheath 2.The connecting section 4 is provided at the proximal end portion of the sheath 2.The connecting section 4 has a communication passage 41, which allows communication from the distal end to the proximal end along the longitudinal axis L, formed therein.","A lumen 21 of the sheath 2 communicates with the interior of the balloon 3 and a communication passage 41 of the connecting section 4.Therefore, the balloon 3 can be inflated, by supplying fluid to the balloon 3 via the communication passage 41 and the lumen 21, using a syringe or the like connected to the connecting section 4 or the like.","At the distal end portion of the sheath 2, a marker 22 capable of being checked under X-ray fluoroscopy is provided.","The balloon 3 is a bag-like member made up of, for example, a transparent film (for example, PEBAX (registered trademark) manufactured by ARKEMA Co.) made of polyamide resin.","The balloon 3 is folded by forming folds such that a plurality of wing sections extending in the longitudinal direction are formed after forming the material into a substantially cylindrical shape.","Hereinafter, a shape in which a diameter is reduced by this folding is referred to as an “initial shape” of the balloon 3.Details of the initial shape will be described later.","When the fluid is injected, the balloon 3 is deployed while unfolding by the wing section spreading, and inflates to a substantially cylindrical shape.","In this way, a shape after inflating substantially only by unfolding is hereinafter referred to as the “inflated shape” of the balloon 3.By removing the fluid injected into the inflated balloon 3, the balloon 3 can fold again and deflate in a dimension in a radial direction.","When the internal pressure of the balloon 3 having the inflated shape becomes a predetermined value or more, the balloon 3 expands to increase in diameter, while the constituent film stretches.","That is, the balloon 3 is a so-called semi-compliant balloon.","The distal end tip 5 is provided at the distal end of the treatment instrument for the endoscope 1.The distal end tip 5 is a substantially conical member extending in the direction of the longitudinal axis L, and its distal end portion is formed in a spherical shape in order to prevent damage to tissue when inserted into a body cavity.","The distal end portion of the balloon 3 is tightly fixed to the proximal end portion of the distal end tip 5.The stylet 6 is a shaft member, is inserted through the inside of the balloon 3, and extends along the longitudinal axis L from the distal end to the proximal end of the balloon 3.The distal end portion of the stylet 6 is connected to the proximal end of the distal end tip 5.The stylet 6 extends through the interior of the balloon 3, the lumen 21 of the sheath 2, and the communication passage 41 of the connecting section 4 and is fixed to the inner wall of the communication passage 41 of the connecting section 4.The stylet 6 is made of, for example, stainless steel, a nickel-titanium alloy or the like.","FIG.","2 illustrates the initial shape which is the shape of the balloon 3 before inflation.","In the initial configuration, the balloon 3 has a first region 31 adjacent to the distal end tip 5, a second region 32 adjacent to the sheath 2, and an intermediate section 33 between the first region 31 and the second region 32.An outer diameter D1 of the first region 31 and the second region 32 located at both ends in the longitudinal direction (the same as an axial direction of the balloon 3) of the balloon 3 is larger than an outer diameter D2 of the intermediate section 33.A method of a folding process for forming the aforementioned initial shape will be described.","The folding process of the balloon 3 is performed by combining the folding process illustrated in FIGS.","3 and 4 and the winding process illustrated in FIGS.","5 and 6.First, as illustrated in FIG.","3, a plurality of folding members 100 are brought into close contact with each other from the outer side of the balloon 3 in the radial direction.","Then, part of the balloon 3 is sandwiched between the folding members 100 and bent.","Thus, as illustrated in FIG.","4, a folding line 35 extending in the longitudinal direction of the balloon 3 is formed, and the balloon 3 has a plurality of wing sections 36 formed to protrude radially outward with the folding line 35 as a ridge line.","The number of wing sections 36 to be formed can be appropriately set by changing the number of folding members 100.Next, as illustrated in FIG.","5, a plurality of diaphragm members 101 are brought into close contact with each other from the radially outer side of the balloon 3 having the wing section 36 formed thereon.","By combining the plurality of the diaphragm members 101, a columnar internal space can be formed at the center portion thereof, and by appropriately relatively moving the plurality of diaphragm members 101, it is possible to change the dimension of the internal space in the radial direction.","When the plurality of diaphragm members 101 are relatively moved in the state of the balloon 3 being disposed in the internal space and the radial dimension of the internal space is gradually reduced, the diaphragm member 101 and the ridge line of the wing section 36 are first brought into contact with each other.","Thereafter, due to friction between the diaphragm member 101 and the wing section 36, the ridge line of the wing section 36 moves in the circumferential direction of the balloon 3, and the protruding direction of the wing section 36 is inclined in the circumferential direction.","Thereafter, as the radial dimension of the internal space is reduced, as illustrated in FIG.","6, the wing section 36 is wound around the axis of the balloon 3 about the stylet 6 to provide curling.","At this time, a plurality of valley sections 37 are formed to protrude radially inward at a base side of the wing section 36.The outer diameter of the curled balloon 3 is substantially the same as the inner diameter of the internal space formed by the diaphragm member 101.Accordingly, a pair of diaphragm members 101 having sizes corresponding to the first region 31, the second region 32, and the intermediate section 33 are prepared, respectively, and the diaphragm member 101 disposed around the first region 31 and the second region 32 is relatively moved until the inner diameter of the internal space becomes D1, and the diaphragm member 101 disposed around the intermediate section 33 is relatively moved until the inner diameter of the internal space becomes D2.Accordingly, it is possible to form the balloon 3 having the initial shape illustrated in FIG.","2.The above-described forming method of the initial shape is an example, and the method for forming the balloon according to the present embodiment is not limited thereto.","In the balloon 3 having this initial shape, the amount of residual strain differs between the first region 31, the second region 32 and the intermediate section 33, due to a difference in amount of deformation of the film caused by the folding process.","In the present specification, the “amount of residual strain” means the total amount of residual strain within a predetermined unit length range in the axial direction of the balloon.","When a certain region has a length equal to or longer than the unit length in the axial direction, the amount of residual strain per unit length calculated by averaging the amount of residual strain of each part is taken as the amount of residual strain in the region.","In the balloon 3 having the initial shape, the residual strain exclusively occurs in the portion of the folding line 35, which is the top portion of the wing section 36, and the valley section 37 bent so as to be convex toward the stylet 6 at the middle between two adjacent wing sections 36.As the amount of deformation occurring in the film constituting the balloon 3 due to the folding process increases, the residual strain generated in the folding line 35 and the valley section 37 increases.","Accordingly, the balloon 3 according to the present embodiment is configured so that the amount of residual strain is larger in the intermediate section 33 than in the first region 31 and the second region 32.In the aforementioned method for forming the initial shape, it is possible to adjust the amount of deformation of the balloon 3, for example, by adjusting the movement distance of the diaphragm member 101 inward in the radial direction of the balloon at the time of the winding process.","Therefore, in the balloon 3 according to the present embodiment, at the time of forming the initial shape, by setting the movement distance of the diaphragm member 101 disposed around the intermediate section 33 to be larger than the movement distance of the diaphragm member 101 disposed around the first region 31 and the second region 32, the amount of deformation of the intermediate section 33 is set to be larger than the amounts of deformation of the first region 31 and the second region 32.Therefore, the amount of residual strain in the intermediate section 33 can be set to be larger than the amount of residual strain in the first region 31 and the second region 32.The method for adjusting the amount of residual strain is not limited thereto, and for example, by setting the amount of driving force of the diaphragm member 101 at the time of winding process, or the amount of driving force or movement distance of the folding member 100 at the time of folding process, the amount of residual strain may be set to be larger at the intermediate section 33 than at the first region 31 and the second region 32.Further, the amount of residual strain may be adjusted by performing a heat treatment on the balloon 3 at the time of winding process or the folding processing.","An operation at the time of use of the treatment instrument for the endoscope 1 configured as described above will be described.","The treatment instrument for the endoscope 1 is introduced into the body of the patient P via a channel provided in the insertion portion 151 of the endoscope 150.As illustrated in FIG.","7, the user connects an inflator 200 to the connecting section 4, and inserts the inflator into the insertion portion 151 from a forceps port 152 of the endoscope 150.Thereafter, the endoscope 150 is inserted into the body of the patient P, and the distal end of the endoscope 150 is moved forward to a region in which the dilation procedure is performed, for example, to the vicinity of a predetermined part of the esophagus.","Connection between the treatment instrument for the endoscope 1 and the inflator 200 or insertion of the treatment instrument for the endoscope 1 into the endoscope 150 may be performed after the endoscope 150 is inserted into the body of the patient P. While observing a target site to be subjected to the dilation procedure with the endoscope 150, the user causes the instrument for an endoscope 1 to protrude from the endoscope 150 and inserts the distal end tip 5 into the target site.","The user further moves the treatment instrument for the endoscope 1 forward and holds the treatment instrument for the endoscope 1 so that the balloon 3 breaks through the target site, that is, the distal end portion and the proximal end portion of the balloon 3 are located on the distal side and the proximal side with respect to the target site, respectively.","The user actuates the inflator 200 to supply a fluid such as water or air to the balloon 3.The balloon 3 inflates while the internal pressure is raised by the supplied fluid.","Since the amount of residual strain of the intermediate section 33 is larger than that of the first region 31 and the second region 32, a larger force is required such that the folding line 35 and the valley section 37 linearly stretch and the wing section 36 spreads.","FIG.","8 is a graph illustrating a relationship between the internal pressure of the balloon 3 and the outer diameters of the first region 31, the second region 32, and the intermediate section 33.In a state in which the internal pressure of the balloon 3 has reached a predetermined first internal pressure value P1 due to the supply of the fluid, in the first region 31 and the second region 32, unfolding has progressed faster than at the intermediate section 33.On the other hand, since the progress of unfolding of the intermediate section 33 is slow, the diameter of the intermediate section 33 is smaller than that of the first region 31 and the second region 32, and the balloon 3 overall has a dumbbell shape as illustrated in FIG.","9.Therefore, even if the balloon 3 slips due to mucus or the like on the surface of the luminal organ, the first region 31 and the second region 32 serve as an anchor to suppress the movement, and thereby a situation such as detachment of the balloon 3 from the target site St is suitably prevented.","In FIG.","9, the shape of the intermediate section 33 illustrates the same state as the initial shape, but this is an example, and it is obvious that the shape may be a state when the intermediate section starts to inflate.","When the internal pressure of the balloon 3 reaches the second internal pressure value P2, which is higher than the first internal pressure value, the folding is released at all of the first region 31, the second region 32, and the intermediate section 33, and the balloon 3 is restored to almost a substantially cylindrical shape (inflated shape) before the folding process as illustrated in FIG.","10.At this time, the radial dimensions of the first region 31, the second region 32, and the intermediate section 33 are the same or substantially the same.","Since the intermediate section 33 inflates to substantially the same diameter as the first region 31 and the second region 32, the target site St can be sufficiently dilated.","At the second internal pressure value P2, the film itself forming the balloon 3 is hardly stretched.","Here, since the balloon 3 is a semi-compliant type, by setting the internal pressure to be larger than a third internal pressure value P3 which is higher than the second internal pressure value as necessary, the whole of the balloon 3 is further inflated, while stretching the material, and a larger dilation force can be applied to the target site St.","In more detail, since the material forming the balloon 3 itself hardly stretches until the internal pressure of the balloon 3 reaches the second internal pressure value P2, the balloon 3 inflates exclusively depending on the progress of unfolding, and the outer diameters of the first region 31, the second region 32, and the intermediate section 33 increase.","Since the folding is almost released after the internal pressure of the balloon 3 reaches the second internal pressure value P2, even if the internal pressure rises, almost no increase in the external diameter occurs.","When the internal pressure of the balloon 3 rises further and becomes larger than the third internal pressure value P3, the film material forming the balloon 3 starts to stretch.","However, since expansion due to the progress of unfolding hardly occurs, the outer diameters of the first region 31, the second region 32, and the intermediate section 33 increase exclusively depending on the stretching of the film material.","As described above, according to the treatment instrument for the endoscope 1 of the present embodiment, the amount of residual strain of the intermediate section 33 in the balloon 3 is set to be larger than the amount of residual strain of the first region 31 and the second region 32 disposed with the intermediate section 33 interposed therebetween.","As a result, at the first internal pressure value P1, a dumbbell shape in which the first region 31 and the second region 32 have inflated to have an outer diameter larger than that of the intermediate section 33 is obtained, and it is possible to suitably prevent the balloon from being detached or displaced from the target site St during the treatment process on the target site St. Further, at the second internal pressure value P2, the intermediate section 33 can be inflated to substantially the same diameter as the first region 31 and the second region 32, and the target site St can be sufficiently dilated.","As a result, prevention of misalignment with respect to the target site and sufficient expansion of the target site are compatible, and it is possible to perform an appropriate expansion treatment at the target site such as a stenosed part.","In the present embodiment, the first internal pressure value and the second internal pressure value can be set to desired values, by appropriately setting the amounts of residual strain of the first region 31, the second region 32, and the intermediate section 33.The second internal pressure value may be set on the basis of the pressure intended to act on the target site, and may be, for example, 3 atmospheres (atm).","It is preferable to set the first internal pressure value to be sufficiently lower than the second internal pressure value, for example, 0.5 atm, so that the positional deviation prevention effect can be exhibited at an early stage.","Further, in the aforementioned example, the description has been given of a case where the outer diameter in the initial shape is set to be different between the first region 31, the second region 32, and the intermediate section to set amounts of residual strain of both regions different from each other.","However, the method for setting different amounts of residual strain for both is not limited thereto.","Several methods for generating different amounts of residual strain in the first region 31, the second region 32 and the intermediate section 33 will be described below.","First, by changing an angle formed by the material of the balloon with the folding line 35 between the intermediate section and the other region, the amount of residual strain can be adjusted.","That is, in the folding process, as an angle θ1 illustrated in FIG.","11 decreases, the amount of residual strain increases.","The angle θ1 can be changed, for example, by changing the shape of the surface in contact with the balloon 3 in the folding member 100 described above.","Further, when the radius of curvature of the top of the wing section increases, the amount of residual strain decreases.","Therefore, by forming the folding line 35 at the intermediate section and increasing the radius of curvature of the top of the wing section to such an extent that no ridge line is formed which is clear in the other region, the amount of residual strain at the intermediate section can be relatively increased.","Also, by changing the number of wing sections in the intermediate section and the other region, the amount of residual strain can be adjusted.","As the number of wing sections increases, since the number of folding lines 35 and valley sections 37 increases, the amount of residual strain increases.","In addition, when forming the initial shape, if the diameter is reduced without forming the wing sections, a large number of irregular folding lines folded to be weaker than the folding line 35 are formed.","Thus, the amount of residual strain decreases.","Therefore, it is possible to relatively increase the amount of residual strain in the intermediate section, also by forming the wing section only in the intermediate section and not forming the wing section in the other regions.","Further, when forming the initial shape, if the wing section is pulled and wound while applying tension, the valley section is strongly bent and the amount of residual strain increases.","Therefore, by applying a tension only to the intermediate section or by applying a larger tension to the intermediate section, the amount of residual strain at the intermediate section can be relatively increased.","Furthermore, when incorporating heat treatment at the time of forming the initial shape, the amount of residual strain can be changed, by switching between the presence or absence of heat treatment and the temperature conditions.","In general, the amount of residual strain is higher when the heat treatment is performed, and the amount of residual strain is higher when the heat treatment is performed at a higher temperature.","Therefore, by applying a heat treatment only to the intermediate section or by setting the temperature of the heat treatment at the intermediate section to be higher than at other regions, the amount of residual strain at the intermediate section can be relatively increased.","Further, when the material of the balloon 3 is partially modified, the amount of residual strain at the intermediate section can be set to be relatively large without changing the process at the time of forming the initial shape for each region.","For example, by forming a balloon with a crosslinked polymer and accelerating crosslinking by irradiating only the intermediate section with an electron beam, the rigidity of the intermediate section is relatively enhanced.","When a uniform initial shape forming process is performed on this balloon, since the degree of plastic deformation becomes strong at the intermediate section, the amount of residual strain increases.","Each of the above-described methods can be appropriately combined, respectively.","Since the amounts of residual strain of each region change complicatedly in combination, for example, it is also possible to set the amount of residual strain of the intermediate section 33 to be relatively large, while setting the outer diameters of the first region 31, the second region 32, and the intermediate section 33 in the initial shape to be the same or substantially the same.","Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and changes in design and the like within the scope not departing from the gist of the present invention are also included.","Further, the constituent elements described in each of the embodiments and each of the modified examples described above can be configured by being appropriately combined.","For example, in the above-described embodiment, the example in which the stylet 6 is inserted into the balloon 3 has been described.","However, a configuration in which a sheath having a guide wire lumen and a fluid supply lumen is inserted through the balloon instead of the stylet may be provided.","In this case, the guide wire inserted into the guide wire lumen can be made to protrude to the distal end of the balloon, and can be used as a guide for breaking through a site in which a strong constriction occurs, an occlusion part or the like.","Further, as in the modified example illustrated in FIG.","12, a marker 40 that is visible under endoscope observation or under X-ray fluoroscopy may be provided at a boundary between the first region 31, the second region 32, and the intermediate section 33.With this configuration, the balloon can be disposed at a more appropriate position with respect to the target site, and the positional deviation prevention effect can be reliably exerted.","As long as the boundary between the intermediate section and another region can be recognized, the marker 40 may be provided in either the intermediate section or the other region.","Further, in the initial shape of the balloon, when the outer diameter difference between the intermediate section and another region is large, a step caused by the outer diameter difference can be used as a marker that can be visually recognized under endoscope observation.","Furthermore, at the time of shipping of the treatment instrument for the endoscope of the present invention, as illustrated in a modified example illustrated in FIG.","13, the balloon 3 may be covered with a cover 70 having an internal space corresponding to the initial shape.","In this way, it is possible to suitably maintain the initial shape until usage and to suppress change in amount of residual strain or the like.","Further, in the above embodiment, an example in which the balloon is a semi-compliant type has been described.","However, a so-called non-compliant type balloon in which, even if the internal pressure is equal to or higher than the second internal pressure value, the material forming the balloon does not substantially stretch, may be used."]],"string":"[\n [\n \"TREATMENT INSTRUMENT FOR ENDOSCOPE\",\n \"A treatment instrument for an endoscope is equipped with a sheath; and a balloon which is provided at the sheath, the balloon

cross-sectional view illustrating a treatment instrument for the endoscope 1 according to this embodiment.\",\n \"The treatment instrument for the endoscope 1 is equipped with a sheath 2, a balloon 3, a connecting section 4, a distal end tip 5, and a stylet 6.The sheath 2 is a member which has a lumen 21, is long in a direction of a longitudinal axis L, and has flexibility.\",\n \"A proximal end portion of the balloon 3 is tightly connected to the distal end portion of the sheath 2.The connecting section 4 is provided at the proximal end portion of the sheath 2.The connecting section 4 has a communication passage 41, which allows communication from the distal end to the proximal end along the longitudinal axis L, formed therein.\",\n \"A lumen 21 of the sheath 2 communicates with the interior of the balloon 3 and a communication passage 41 of the connecting section 4.Therefore, the balloon 3 can be inflated, by supplying fluid to the balloon 3 via the communication passage 41 and the lumen 21, using a syringe or the like connected to the connecting section 4 or the like.\",\n \"At the distal end portion of the sheath 2, a marker 22 capable of being checked under X-ray fluoroscopy is provided.\",\n \"The balloon 3 is a bag-like member made up of, for example, a transparent film (for example, PEBAX (registered trademark) manufactured by ARKEMA Co.) made of polyamide resin.\",\n \"The balloon 3 is folded by forming folds such that a plurality of wing sections extending in the longitudinal direction are formed after forming the material into a substantially cylindrical shape.\",\n \"Hereinafter, a shape in which a diameter is reduced by this folding is referred to as an “initial shape” of the balloon 3.Details of the initial shape will be described later.\",\n \"When the fluid is injected, the balloon 3 is deployed while unfolding by the wing section spreading, and inflates to a substantially cylindrical shape.\",\n \"In this way, a shape after inflating substantially only by unfolding is hereinafter referred to as the “inflated shape” of the balloon 3.By removing the fluid injected into the inflated balloon 3, the balloon 3 can fold again and deflate in a dimension in a radial direction.\",\n \"When the internal pressure of the balloon 3 having the inflated shape becomes a predetermined value or more, the balloon 3 expands to increase in diameter, while the constituent film stretches.\",\n \"That is, the balloon 3 is a so-called semi-compliant balloon.\",\n \"The distal end tip 5 is provided at the distal end of the treatment instrument for the endoscope 1.The distal end tip 5 is a substantially conical member extending in the direction of the longitudinal axis L, and its distal end portion is formed in a spherical shape in order to prevent damage to tissue when inserted into a body cavity.\",\n \"The distal end portion of the balloon 3 is tightly fixed to the proximal end portion of the distal end tip 5.The stylet 6 is a shaft member, is inserted through the inside of the balloon 3, and extends along the longitudinal axis L from the distal end to the proximal end of the balloon 3.The distal end portion of the stylet 6 is connected to the proximal end of the distal end tip 5.The stylet 6 extends through the interior of the balloon 3, the lumen 21 of the sheath 2, and the communication passage 41 of the connecting section 4 and is fixed to the inner wall of the communication passage 41 of the connecting section 4.The stylet 6 is made of, for example, stainless steel, a nickel-titanium alloy or the like.\",\n \"FIG.\",\n \"2 illustrates the initial shape which is the shape of the balloon 3 before inflation.\",\n \"In the initial configuration, the balloon 3 has a first region 31 adjacent to the distal end tip 5, a second region 32 adjacent to the sheath 2, and an intermediate section 33 between the first region 31 and the second region 32.An outer diameter D1 of the first region 31 and the second region 32 located at both ends in the longitudinal direction (the same as an axial direction of the balloon 3) of the balloon 3 is larger than an outer diameter D2 of the intermediate section 33.A method of a folding process for forming the aforementioned initial shape will be described.\",\n \"The folding process of the balloon 3 is performed by combining the folding process illustrated in FIGS.\",\n \"3 and 4 and the winding process illustrated in FIGS.\",\n \"5 and 6.First, as illustrated in FIG.\",\n \"3, a plurality of folding members 100 are brought into close contact with each other from the outer side of the balloon 3 in the radial direction.\",\n \"Then, part of the balloon 3 is sandwiched between the folding members 100 and bent.\",\n \"Thus, as illustrated in FIG.\",\n \"4, a folding line 35 extending in the longitudinal direction of the balloon 3 is formed, and the balloon 3 has a plurality of wing sections 36 formed to protrude radially outward with the folding line 35 as a ridge line.\",\n \"The number of wing sections 36 to be formed can be appropriately set by changing the number of folding members 100.Next, as illustrated in FIG.\",\n \"5, a plurality of diaphragm members 101 are brought into close contact with each other from the radially outer side of the balloon 3 having the wing section 36 formed thereon.\",\n \"By combining the plurality of the diaphragm members 101, a columnar internal space can be formed at the center portion thereof, and by appropriately relatively moving the plurality of diaphragm members 101, it is possible to change the dimension of the internal space in the radial direction.\",\n \"When the plurality of diaphragm members 101 are relatively moved in the state of the balloon 3 being disposed in the internal space and the radial dimension of the internal space is gradually reduced, the diaphragm member 101 and the ridge line of the wing section 36 are first brought into contact with each other.\",\n \"Thereafter, due to friction between the diaphragm member 101 and the wing section 36, the ridge line of the wing section 36 moves in the circumferential direction of the balloon 3, and the protruding direction of the wing section 36 is inclined in the circumferential direction.\",\n \"Thereafter, as the radial dimension of the internal space is reduced, as illustrated in FIG.\",\n \"6, the wing section 36 is wound around the axis of the balloon 3 about the stylet 6 to provide curling.\",\n \"At this time, a plurality of valley sections 37 are formed to protrude radially inward at a base side of the wing section 36.The outer diameter of the curled balloon 3 is substantially the same as the inner diameter of the internal space formed by the diaphragm member 101.Accordingly, a pair of diaphragm members 101 having sizes corresponding to the first region 31, the second region 32, and the intermediate section 33 are prepared, respectively, and the diaphragm member 101 disposed around the first region 31 and the second region 32 is relatively moved until the inner diameter of the internal space becomes D1, and the diaphragm member 101 disposed around the intermediate section 33 is relatively moved until the inner diameter of the internal space becomes D2.Accordingly, it is possible to form the balloon 3 having the initial shape illustrated in FIG.\",\n \"2.The above-described forming method of the initial shape is an example, and the method for forming the balloon according to the present embodiment is not limited thereto.\",\n \"In the balloon 3 having this initial shape, the amount of residual strain differs between the first region 31, the second region 32 and the intermediate section 33, due to a difference in amount of deformation of the film caused by the folding process.\",\n \"In the present specification, the “amount of residual strain” means the total amount of residual strain within a predetermined unit length range in the axial direction of the balloon.\",\n \"When a certain region has a length equal to or longer than the unit length in the axial direction, the amount of residual strain per unit length calculated by averaging the amount of residual strain of each part is taken as the amount of residual strain in the region.\",\n \"In the balloon 3 having the initial shape, the residual strain exclusively occurs in the portion of the folding line 35, which is the top portion of the wing section 36, and the valley section 37 bent so as to be convex toward the stylet 6 at the middle between two adjacent wing sections 36.As the amount of deformation occurring in the film constituting the balloon 3 due to the folding process increases, the residual strain generated in the folding line 35 and the valley section 37 increases.\",\n \"Accordingly, the balloon 3 according to the present embodiment is configured so that the amount of residual strain is larger in the intermediate section 33 than in the first region 31 and the second region 32.In the aforementioned method for forming the initial shape, it is possible to adjust the amount of deformation of the balloon 3, for example, by adjusting the movement distance of the diaphragm member 101 inward in the radial direction of the balloon at the time of the winding process.\",\n \"Therefore, in the balloon 3 according to the present embodiment, at the time of forming the initial shape, by setting the movement distance of the diaphragm member 101 disposed around the intermediate section 33 to be larger than the movement distance of the diaphragm member 101 disposed around the first region 31 and the second region 32, the amount of deformation of the intermediate section 33 is set to be larger than the amounts of deformation of the first region 31 and the second region 32.Therefore, the amount of residual strain in the intermediate section 33 can be set to be larger than the amount of residual strain in the first region 31 and the second region 32.The method for adjusting the amount of residual strain is not limited thereto, and for example, by setting the amount of driving force of the diaphragm member 101 at the time of winding process, or the amount of driving force or movement distance of the folding member 100 at the time of folding process, the amount of residual strain may be set to be larger at the intermediate section 33 than at the first region 31 and the second region 32.Further, the amount of residual strain may be adjusted by performing a heat treatment on the balloon 3 at the time of winding process or the folding processing.\",\n \"An operation at the time of use of the treatment instrument for the endoscope 1 configured as described above will be described.\",\n \"The treatment instrument for the endoscope 1 is introduced into the body of the patient P via a channel provided in the insertion portion 151 of the endoscope 150.As illustrated in FIG.\",\n \"7, the user connects an inflator 200 to the connecting section 4, and inserts the inflator into the insertion portion 151 from a forceps port 152 of the endoscope 150.Thereafter, the endoscope 150 is inserted into the body of the patient P, and the distal end of the endoscope 150 is moved forward to a region in which the dilation procedure is performed, for example, to the vicinity of a predetermined part of the esophagus.\",\n \"Connection between the treatment instrument for the endoscope 1 and the inflator 200 or insertion of the treatment instrument for the endoscope 1 into the endoscope 150 may be performed after the endoscope 150 is inserted into the body of the patient P. While observing a target site to be subjected to the dilation procedure with the endoscope 150, the user causes the instrument for an endoscope 1 to protrude from the endoscope 150 and inserts the distal end tip 5 into the target site.\",\n \"The user further moves the treatment instrument for the endoscope 1 forward and holds the treatment instrument for the endoscope 1 so that the balloon 3 breaks through the target site, that is, the distal end portion and the proximal end portion of the balloon 3 are located on the distal side and the proximal side with respect to the target site, respectively.\",\n \"The user actuates the inflator 200 to supply a fluid such as water or air to the balloon 3.The balloon 3 inflates while the internal pressure is raised by the supplied fluid.\",\n \"Since the amount of residual strain of the intermediate section 33 is larger than that of the first region 31 and the second region 32, a larger force is required such that the folding line 35 and the valley section 37 linearly stretch and the wing section 36 spreads.\",\n \"FIG.\",\n \"8 is a graph illustrating a relationship between the internal pressure of the balloon 3 and the outer diameters of the first region 31, the second region 32, and the intermediate section 33.In a state in which the internal pressure of the balloon 3 has reached a predetermined first internal pressure value P1 due to the supply of the fluid, in the first region 31 and the second region 32, unfolding has progressed faster than at the intermediate section 33.On the other hand, since the progress of unfolding of the intermediate section 33 is slow, the diameter of the intermediate section 33 is smaller than that of the first region 31 and the second region 32, and the balloon 3 overall has a dumbbell shape as illustrated in FIG.\",\n \"9.Therefore, even if the balloon 3 slips due to mucus or the like on the surface of the luminal organ, the first region 31 and the second region 32 serve as an anchor to suppress the movement, and thereby a situation such as detachment of the balloon 3 from the target site St is suitably prevented.\",\n \"In FIG.\",\n \"9, the shape of the intermediate section 33 illustrates the same state as the initial shape, but this is an example, and it is obvious that the shape may be a state when the intermediate section starts to inflate.\",\n \"When the internal pressure of the balloon 3 reaches the second internal pressure value P2, which is higher than the first internal pressure value, the folding is released at all of the first region 31, the second region 32, and the intermediate section 33, and the balloon 3 is restored to almost a substantially cylindrical shape (inflated shape) before the folding process as illustrated in FIG.\",\n \"10.At this time, the radial dimensions of the first region 31, the second region 32, and the intermediate section 33 are the same or substantially the same.\",\n \"Since the intermediate section 33 inflates to substantially the same diameter as the first region 31 and the second region 32, the target site St can be sufficiently dilated.\",\n \"At the second internal pressure value P2, the film itself forming the balloon 3 is hardly stretched.\",\n \"Here, since the balloon 3 is a semi-compliant type, by setting the internal pressure to be larger than a third internal pressure value P3 which is higher than the second internal pressure value as necessary, the whole of the balloon 3 is further inflated, while stretching the material, and a larger dilation force can be applied to the target site St.\",\n \"In more detail, since the material forming the balloon 3 itself hardly stretches until the internal pressure of the balloon 3 reaches the second internal pressure value P2, the balloon 3 inflates exclusively depending on the progress of unfolding, and the outer diameters of the first region 31, the second region 32, and the intermediate section 33 increase.\",\n \"Since the folding is almost released after the internal pressure of the balloon 3 reaches the second internal pressure value P2, even if the internal pressure rises, almost no increase in the external diameter occurs.\",\n \"When the internal pressure of the balloon 3 rises further and becomes larger than the third internal pressure value P3, the film material forming the balloon 3 starts to stretch.\",\n \"However, since expansion due to the progress of unfolding hardly occurs, the outer diameters of the first region 31, the second region 32, and the intermediate section 33 increase exclusively depending on the stretching of the film material.\",\n \"As described above, according to the treatment instrument for the endoscope 1 of the present embodiment, the amount of residual strain of the intermediate section 33 in the balloon 3 is set to be larger than the amount of residual strain of the first region 31 and the second region 32 disposed with the intermediate section 33 interposed therebetween.\",\n \"As a result, at the first internal pressure value P1, a dumbbell shape in which the first region 31 and the second region 32 have inflated to have an outer diameter larger than that of the intermediate section 33 is obtained, and it is possible to suitably prevent the balloon from being detached or displaced from the target site St during the treatment process on the target site St. Further, at the second internal pressure value P2, the intermediate section 33 can be inflated to substantially the same diameter as the first region 31 and the second region 32, and the target site St can be sufficiently dilated.\",\n \"As a result, prevention of misalignment with respect to the target site and sufficient expansion of the target site are compatible, and it is possible to perform an appropriate expansion treatment at the target site such as a stenosed part.\",\n \"In the present embodiment, the first internal pressure value and the second internal pressure value can be set to desired values, by appropriately setting the amounts of residual strain of the first region 31, the second region 32, and the intermediate section 33.The second internal pressure value may be set on the basis of the pressure intended to act on the target site, and may be, for example, 3 atmospheres (atm).\",\n \"It is preferable to set the first internal pressure value to be sufficiently lower than the second internal pressure value, for example, 0.5 atm, so that the positional deviation prevention effect can be exhibited at an early stage.\",\n \"Further, in the aforementioned example, the description has been given of a case where the outer diameter in the initial shape is set to be different between the first region 31, the second region 32, and the intermediate section to set amounts of residual strain of both regions different from each other.\",\n \"However, the method for setting different amounts of residual strain for both is not limited thereto.\",\n \"Several methods for generating different amounts of residual strain in the first region 31, the second region 32 and the intermediate section 33 will be described below.\",\n \"First, by changing an angle formed by the material of the balloon with the folding line 35 between the intermediate section and the other region, the amount of residual strain can be adjusted.\",\n \"That is, in the folding process, as an angle θ1 illustrated in FIG.\",\n \"11 decreases, the amount of residual strain increases.\",\n \"The angle θ1 can be changed, for example, by changing the shape of the surface in contact with the balloon 3 in the folding member 100 described above.\",\n \"Further, when the radius of curvature of the top of the wing section increases, the amount of residual strain decreases.\",\n \"Therefore, by forming the folding line 35 at the intermediate section and increasing the radius of curvature of the top of the wing section to such an extent that no ridge line is formed which is clear in the other region, the amount of residual strain at the intermediate section can be relatively increased.\",\n \"Also, by changing the number of wing sections in the intermediate section and the other region, the amount of residual strain can be adjusted.\",\n \"As the number of wing sections increases, since the number of folding lines 35 and valley sections 37 increases, the amount of residual strain increases.\",\n \"In addition, when forming the initial shape, if the diameter is reduced without forming the wing sections, a large number of irregular folding lines folded to be weaker than the folding line 35 are formed.\",\n \"Thus, the amount of residual strain decreases.\",\n \"Therefore, it is possible to relatively increase the amount of residual strain in the intermediate section, also by forming the wing section only in the intermediate section and not forming the wing section in the other regions.\",\n \"Further, when forming the initial shape, if the wing section is pulled and wound while applying tension, the valley section is strongly bent and the amount of residual strain increases.\",\n \"Therefore, by applying a tension only to the intermediate section or by applying a larger tension to the intermediate section, the amount of residual strain at the intermediate section can be relatively increased.\",\n \"Furthermore, when incorporating heat treatment at the time of forming the initial shape, the amount of residual strain can be changed, by switching between the presence or absence of heat treatment and the temperature conditions.\",\n \"In general, the amount of residual strain is higher when the heat treatment is performed, and the amount of residual strain is higher when the heat treatment is performed at a higher temperature.\",\n \"Therefore, by applying a heat treatment only to the intermediate section or by setting the temperature of the heat treatment at the intermediate section to be higher than at other regions, the amount of residual strain at the intermediate section can be relatively increased.\",\n \"Further, when the material of the balloon 3 is partially modified, the amount of residual strain at the intermediate section can be set to be relatively large without changing the process at the time of forming the initial shape for each region.\",\n \"For example, by forming a balloon with a crosslinked polymer and accelerating crosslinking by irradiating only the intermediate section with an electron beam, the rigidity of the intermediate section is relatively enhanced.\",\n \"When a uniform initial shape forming process is performed on this balloon, since the degree of plastic deformation becomes strong at the intermediate section, the amount of residual strain increases.\",\n \"Each of the above-described methods can be appropriately combined, respectively.\",\n \"Since the amounts of residual strain of each region change complicatedly in combination, for example, it is also possible to set the amount of residual strain of the intermediate section 33 to be relatively large, while setting the outer diameters of the first region 31, the second region 32, and the intermediate section 33 in the initial shape to be the same or substantially the same.\",\n \"Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and changes in design and the like within the scope not departing from the gist of the present invention are also included.\",\n \"Further, the constituent elements described in each of the embodiments and each of the modified examples described above can be configured by being appropriately combined.\",\n \"For example, in the above-described embodiment, the example in which the stylet 6 is inserted into the balloon 3 has been described.\",\n \"However, a configuration in which a sheath having a guide wire lumen and a fluid supply lumen is inserted through the balloon instead of the stylet may be provided.\",\n \"In this case, the guide wire inserted into the guide wire lumen can be made to protrude to the distal end of the balloon, and can be used as a guide for breaking through a site in which a strong constriction occurs, an occlusion part or the like.\",\n \"Further, as in the modified example illustrated in FIG.\",\n \"12, a marker 40 that is visible under endoscope observation or under X-ray fluoroscopy may be provided at a boundary between the first region 31, the second region 32, and the intermediate section 33.With this configuration, the balloon can be disposed at a more appropriate position with respect to the target site, and the positional deviation prevention effect can be reliably exerted.\",\n \"As long as the boundary between the intermediate section and another region can be recognized, the marker 40 may be provided in either the intermediate section or the other region.\",\n \"Further, in the initial shape of the balloon, when the outer diameter difference between the intermediate section and another region is large, a step caused by the outer diameter difference can be used as a marker that can be visually recognized under endoscope observation.\",\n \"Furthermore, at the time of shipping of the treatment instrument for the endoscope of the present invention, as illustrated in a modified example illustrated in FIG.\",\n \"13, the balloon 3 may be covered with a cover 70 having an internal space corresponding to the initial shape.\",\n \"In this way, it is possible to suitably maintain the initial shape until usage and to suppress change in amount of residual strain or the like.\",\n \"Further, in the above embodiment, an example in which the balloon is a semi-compliant type has been described.\",\n \"However, a so-called non-compliant type balloon in which, even if the internal pressure is equal to or higher than the second internal pressure value, the material forming the balloon does not substantially stretch, may be used.\"\n

governor system of FIG.","6 with the elliptical gear set in a second operating position.","DETAILED DESCRIPTION Before turning to the figures, which illustrate the exemplary embodiments in detail, it should be understood that the application is not limited to the details or methodology set forth in the description or illustrated in the figures.","It should also be understood that the terminology is for the purpose of description only and should not be regarded as limiting.","Referring to FIGS.","1-2 and 4-5, an electronic governor system is illustrated according to an exemplary embodiment.","The electronic governor system 100 is shown in use on a small engine 105.The electronic governor system 100 includes a carburetor 110, a motor 115 (e.g., a direct current (“DC”) motor), a transmission 120, a throttle plate 125, a throttle lever 130 and a linkage 135 connecting the throttle lever to the transmission.","In the carburetor 110, fuel is mixed with air to produce an air/fuel mixture for combustion in one or more cylinders of the engine 105.The throttle plate 125 controls the flow of the air/fuel mixture out of the carburetor 110 and in doing so controls the speed of the engine 105.As illustrated, the linkage 135 includes a link 140 and a crank arm 145.In some embodiments the electronic governor system 100 also includes an encoder 150 that is coupled to the motor 115 and the transmission 120.The motor assembly (i.e., the motor 115 and the transmission 120) is used to control the position of the throttle plate 125, thereby controlling the engine speed.","The throttle plate 125 is movable between a closed position and a wide-open position.","The position of the throttle plate 125 is adjusted so that the engine speed is maintained at a desired engine speed.","The desired engine speed can be a constant or can be varied by a user or a controller in response to inputs from the engine (e.g., inputs related to engine load, desired output, or other engine operating conditions or objectives).","The motor 115 is relatively low cost, particularly with respect to the stepper motor typically used in other electronic governor systems.","The motor 115 does not track steps of the motor's rotation like a stepper motor.","In some embodiments, the motor 115 is a brushed motor.","The transmission 120 provides a large reduction ratio (i.e., input speed/output speed).","For example, the motor 115 may have a top speed of 4,000 revolutions per minute (rpm).","The transmission 120 may provide a reduction so that the output from the transmission turns at 100 rpm (i.e., a 40:1 reduction ratio).","This will result in a transmission output speed that is relatively fast as compared to the amount of rotation necessary to adjust the throttle plate position (e.g., 75 to 100 rpm), with the throttle plate's range of motion (i.e., between the closed position and the wide-open position) being less than a full revolution, and produces a relatively large amount of torque.","At this relatively fast transmission output speed the throttle plate 125 is able to move from closed to wide open in about 40 milliseconds.","As another example, the motor 115 may have an output speed of at about 10,000 rpm and the transmission may provide a gear reduction such that the output of the transmission is about 60 rpm (i.e.","a reduction ratio of about 167:1).","In some embodiments, the transmission 120 is a series of gears that provides a reduction from the input of the motor to the output of the transmission.","The transmission 120 providing a large reduction ratio produces an output from the transmission 120 with a relatively large amount of torque.","The output shaft of the transmission 120 only needs to rotate a small amount to adjust the throttle plate position within the throttle plate's range of motion and in doing so is able to produce a lot of torque.","Another advantage of this large reduction ratio is that power only needs to be supplied to the motor 115 when moving the output shaft of the transmission 120 to the desired position.","This position corresponds with the desired position of the throttle plate 125.After the output shaft of the transmission 120, and therefore the throttle plate 125, has reached the desired position, the motor 115 is no longer powered (i.e., the motor 115 is turned off).","In this way, power is not needed to maintain the position of the output shaft of the transmission 120 and of the throttle plate 125.The relatively large reduction ratio provided by the transmission 120 is able to maintain or hold the throttle plate 125 in position without power being supplied to the motor 115 to maintain the desired position of the throttle plate 125.In some embodiments several components of the electronic governor system 100 are included within a single housing.","For example, the motor 115 and the transmission 120 could form a single unit.","This unit may be combined with the controller 155 and its associated circuit board.","As shown in FIG.","1, the linkage 135 connects the output shaft of the transmission 120 to the throttle lever 130.The throttle lever 130 is connected to the throttle plate 125, such that the motor 115 drives the transmission 120 which moves the linkage 135 which moves the throttle lever 130 which moves the throttle plate 125.In this way, powering the motor 115 causes the throttle plate 125 to change position.","Though the linkage 135 is shown as a two-piece linkage, other appropriate mechanisms for connecting the output shaft of the transmission 120 to the throttle plate 125 may be utilized.","For example, the output shaft of the transmission 120 could be directly connected to the throttle plate 125 or one or more components could be used to connect the output shaft of the transmission 120 to the throttle plate 125.In some embodiments, one or more gears are used to connect the output shaft of the transmission 120 to the throttle plate 125.In some embodiments, the encoder 150 is connected to the motor 115 and the transmission 120 to determine the position of the output shaft of the transmission 120.In some embodiments, the encoder 150 is an absolute encoder and can be used to keep track of the position of the output shaft of the transmission 120 and therefore the position of the throttle plate 125.As shown in FIG.","2, the electronic governor system 100 includes a controller 155 that controls the operation of the motor 115.In some embodiments, the controller 155 also controls the operation of other components of the electronic governor system 100 that will be described in more detail below.","These components may include an engine speed sensor 160, a user interface 165, a temperature sensor 170, a current sensor 175, an ignition system 180, and a rev limiter 185.Different embodiments of the electronic governor system 100 may include some, none or all of these additional components.","As shown in FIG.","3, the controller 155 includes a processing circuit 190, an input interface 195, and an output interface 200.The processing circuit 190 includes a processor 205 and memory 210.The processing circuit 190 and processor 205 are configured to receive inputs from input interface 195 (e.g., via a wired or wireless communication link with other components of the engine and/or electronic governor system) and to provide an output (e.g., a control signal, an actuator output, etc.)","via output interface 200 (e.g., via a wired or wireless communication link to the motor 115, other components of the engine, and/or other components of the electronic governor system).","The processing circuit 190 can be a circuit containing one or more processing components (e.g., the processor 205) or a group of distributed processing components.","The processor 205 may be a general purpose or specific purpose processor configured to execute computer code or instructions stored in the memory or received from other computer readable media (e.g., CD-ROM, network storage, a remote server, etc.).","The processing circuit 190 is also shown to include the memory 210.Memory 210 may be RAM, hard drive storage, temporary storage, non-volatile memory, flash memory, optical memory, or any other suitable memory for storing software objects and/or computer instructions.","When the processor 205 executes instructions stored in the memory 210 for completing the various activities described herein, the processor 205 generally configures the computer system and more particularly the processing circuit 190 to complete such activities.","The memory 210 may include database components, object code components, script components, and/or any other type of information structure for supporting the various activities described in the present disclosure.","For example, the memory 210 may store data regarding the operation of a controller (e.g., previous setpoints, previous behavior patterns regarding used energy to adjust a current value to a setpoint, etc.).","According to an exemplary embodiment, the memory 210 is communicably connected to the processor 205 and includes computer code for executing one or more processes described herein and the processor 205 is configured to execute the computer code.","The memory 210 is shown to include a feedback control module 215 and an adaptive control module 220.The memory may include a throttle plate position module 225 and an engine shutdown module 230.The feedback control module 215 is the primary logic module configured to provide the feedback-based control activity of the controller 155.In some embodiments, the feedback control module 215 is a proportional-integral-derivative (PID) control module.","In other embodiments, the feedback control module 215 is a fuzzy logic control module.","The feedback control module 215 uses information from the input interface 195 (e.g., detected engine speed) to calculate or otherwise obtain the controlled variable (e.g., throttle plate position).","The feedback control module 215 may also use information stored in the memory 210 (e.g., previous detected engine speed, desired engine speed, etc.)","in calculating or obtaining the controlled variable.","The adaptive control module 220 is configured to determine appropriate values of control parameters (e.g., proportional gain, integral gain, derivative gain, etc.).","The adaptive control module 220 may tune control parameters based on a model identification adaptive control (MIAC) approach or another adaptive tuning approach or algorithm.","The feedback control module 215 is configured to provide an engine speed control output based an engine speed error determined by a comparison of a current engine speed input from the engine speed sensor 160 with the desired engine speed.","The output is provided to the motor 115 to adjust the throttle plate 125 position, thereby controlling the engine speed and correcting any engine speed error so that the detected engine speed and the desired engine speed are the same or substantially the same (e.g., within a predetermined range).","The feedback control module can use different types of feedback control including PID control algorithms or fuzzy logic control rules.","The adaptive control module 220 adjusts one or more parameters (e.g., coefficients, gains, rules, etc.)","of the feedback control module 215 such that the feedback control module learns the appropriate operating parameters for a specific engine and end product (e.g., lawn mower, snow thrower, generator, pressure washer, etc.).","For example, the feedback control module 215 may determine an engine speed error and provide an engine speed output intended to correct that error or a portion of the error (e.g., reduce the error by half).","The adaptive control module 220 determines what an expected engine speed error correction is based on the output provided by the feedback control module 215.The adaptive control module 220 also determines an actual engine speed correction based on the current engine speed input from the engine speed sensor 160 and a previous engine speed input from the engine speed sensor 160.The adaptive control module 220 then is able to determine a correction error based on the expected engine speed error and the actual engine speed correction.","In this way, the adaptive control module 220 is able to determine if the actual engine speed correction is the same as or close to the expected engine speed error correction (e.g., determine a correction error).","If the actual engine speed correction is not the same (or within a predetermined range acceptable as the same) as the expected engine speed correction, the adaptive control module 220 adjusts one or more parameters of the feedback control module 215.When the actual engine speed error correction was less than the expected engine error correction the parameter change is such that the subsequent attempt at correcting engine speed will be more aggressive.","As used herein, more aggressive means that the position change of the throttle plate with adjusted parameter setting will be greater than at the previous parameter setting and less aggressive means that the position change of the throttle plate with adjusted parameter setting will be less than at the previous parameter setting.","For example, in a controller 155 using PID control the adaptive control module 220 can change one or more of the proportional, integral and derivative parameters (e.g., coefficients or gains) of the feedback control module 215 to achieve the desired change in engine speed.","The PID control of the feedback control module 215 may set forth a control algorithm to determine the motor adjustment—the amount of time voltage is supplied to the motor 115 (the duration or “width” of a voltage pulse).","For example, the PID control algorithm may use the following equation to determine the motor adjustment where Error is the engine speed error.","Motor Adjustment = P i Error + D i d Error dt + I i ∫ Error The adaptive control module 220 may be configured to adjust one or more of the proportional, integral and derivative parameters in response to a comparison of the actual change in engine speed following a throttle plate position adjustment (e.g., as measured by the engine speed sensor 160) with the expected change in engine speed following a throttle plate position adjustment (e.g., the engine speed error or a portion (e.g., one half, one third, etc.)","of the engine speed error).","If the actual change in engine speed is less than the expected change in engine speed, one or more of the parameters is adjusted to make the motor adjustment more aggressive (i.e., provide a voltage pulse of a longer duration).","If the actual change in engine speed is greater than the expected change in engine speed, one or more of the parameters is adjusted to make the motor adjustment less aggressive (i.e., provide a voltage pulse of a shorter duration).","The comparison of actual change in engine speed to the expected change in engine speed can be performed at a specific time (e.g., 2-3 engine cycles) after a motor adjustment pulse is sent to the motor 115.In some embodiments, the pulse of the motor adjustment has a duty cycle and the duty cycle of the pulse of the motor adjustment may be adjusted when the actual change in engine speed is different than the expected change in engine speed.","In some embodiments, the motor adjustment algorithm In some embodiments using a PID control algorithm there are multiple parameter sets.","For example, a first parameter set may be used when the throttle plate 125 is close or near to the closed position and a second parameter set may be used when the throttle plate 125 is close or near to the wide open position.","This is helpful because the operating performance (e.g., speed) of the engine is not linear with respect to throttle plate position.","When the throttle plate 125 is near the wide open position, the engine speed is not very responsive to changes in the throttle plate position and when the throttle plate 125 is near the closed position, the engine speed is more responsive to changes in the throttle plate position.","Therefore, the parameter set associated with operation when the throttle plate 125 is near the closed position would be less aggressive than the parameter set that is used when the throttle plate 125 is near the wide open position.","Two or more parameter sets based on the throttle position could be implemented.","For example a curve could be fit so that the parameter sets used change from the closed position to the wide open position.","The adaptive control module 220 may also be configured to perform a comparison of the expected output (i.e., rotational speed) of the motor 115 from a particular duration of applied voltage (voltage pulse) to the back electromotive force (“back-EMF”) actually caused by that particular duration of applied voltage.","Back-EMF is caused by the rotation of the motor and can act as a proxy for a motor sensor for detecting the rotational speed of the motor.","In this way the adaptive control module 220 allows the system to learn or adjust to the operational characteristics of a particular engine.","Variations among particular engines (e.g., individual DC motors, the end use of the engine, etc.)","will result in different duration voltage pulses being necessary to move a throttle plate a specific amount.","For example, in one engine a voltage pulse of 10 milliseconds may move the throttle plate 10 degrees, but may only move the throttle plate of a second engine 5 degrees.","The back-EMF correlation performed by the adaptive control module 220 allows the system to learn the particular voltage pulse duration needed for a particular throttle plate position change within the addition of a motor speed sensor and allows for that correlation to change as engine performance changes over the life of a particular engine.","The back-EMF comparison can also be used to determine when the throttle plate 125 is at either end of its range of motion (i.e., closed position or wide open position) because the throttle plate 125 is at a hard stop at either end of its range of motion and the back-EMF should approach zero as the motor is unable to turn.","The back-EMF comparison can also be used to identify variations between the operational characteristics of individual motors and a curve establishing a known or desired relationship between back-EMF and engine speed (e.g., RPM) and to determine the operational characteristics that need to be modified (e.g., duration of voltage pulses) to fit a specific motor to the known back-EMF and engine speed curve.","As shown in FIGS.","6-7, in some embodiments of the electronic governor system 100, an elliptical gear set 186 is included between the transmission 120 and the throttle lever 130 to account for the non-linearity of engine speed with respect to throttle plate position.","The elliptical gear set 186 includes two elliptical gears—a driving gear 187 and a driven gear 188.The driving gear 187 has a minor radius 189 that is less than a major radius 191.The driving gear 187 is coupled to or a component of the transmission 120.The driven gear 188 is coupled to the throttle plate 125 (e.g., directly or indirectly by one or more links or gears).","The driven gear 188 has a minor radius 192 that is less than a major radius 193.The elliptical gear set 186 is arranged so that the driven gear 188 provides a relatively large amount of movement of the throttle plate 125 in response to specified amount of movement of the driving gear 187 when the throttle plate 125 is near the wide open position (FIG.","6) and so that the driven gear 188 provides a relatively small amount of movement of the throttle plate 125 in response to the same specified amount of movement of the driving gear 187 when the throttle plate 125 is near the closed position (FIG.","7).","As shown in FIG.","6, when the throttle plate 125 is near the wide open position, the major radius 191 of the driving gear 187 engages the minor radius 192 of the driven gear 188.As shown in FIG.","7, when the throttle plate 125 is near the closed position, the minor radius 189 of the driving gear 187 engages the major radius 193 of the driven gear 188.In embodiments where the feedback control module 215 uses a fuzzy logic control algorithm to control the output to the motor 115, a list of fuzzy logic rules is created to control the operation of the motor 115.These rules allow for non-linear control of the non-linear engine operation.","In some embodiments, the temperature sensor 170 provides the detected temperature as an input to the fuzzy logic rule set.","In some embodiments the electronic governor system 100 includes a temperature sensor 170.The temperature sensor 170 is configured to detect a temperature (e.g., an ambient temperature, an engine temperature, or other appropriate temperature).","The detected temperature is provided as an input to the controller 155 and may be utilized as an input to the various logic modules of the controller 155.As the engine may operate differently as relatively cold temperatures and relatively hot temperatures different control parameters (e.g., of the feedback control module 215 and/or the adaptive control module 220) can be used when the detected temperature is either below or above one or more thresholds (e.g.","a hot operating condition threshold and a cold operating condition threshold).","The memory 210 may also include a throttle plate position module 225.The throttle plate position module 225 is configured to determine the position of the throttle plate 125 based on tracking the expected changes in the throttle plate position from an initial throttle plate position.","The initial throttle plate position is known.","For example, the wide open position may be considered to be 90° and the closed position may be considered to be 0°.","Based on that starting position (e.g., the wide open position), the throttle plate position module 225 calculates a current throttle plate position based on the changes to the throttle plate position caused by the motor 115.The product of the voltage applied to the motor 115 and the amount of time for which that voltage is supplied corresponds to an expected change in the position of the throttle plate 125.By keeping track of all expected movements of the throttle plate 125 from the initial known position caused by operation of the motor 115, the throttle plate position module 225 is able to track the position of the throttle plate 125.Alternatively, an encoder (e.g., the encoder 150) may keep track of the throttle plate position.","However, an encoder adds cost that may not be necessary for the electronic governor system 100 to operate as desired.","The engine 105 includes an ignition system 180.In some embodiments excess energy from the ignition system 180 is used to power the motor 115 and/or the controller 155.In this way the electronic governor system 100 is able to operate without a separate or dedicated power supply (e.g., a separate battery or the battery used to power an electric engine starting system).","In a magneto or spark ignition system extra energy in the form of ignition sparks or pulses can be harvested and stored in a capacitor or other energy storage device (e.g., battery) for use to power the motor 115.Though a spark based ignition system is discussed as an example other types of ignition systems are possible.","The excess energy of the ignition system may also be sufficient to power the motor 115 and/or the controller 155.After the engine 105 is started, there is a relatively abundant amount of excess energy that can be harvested to power the electronic governor system 100.For example, the energy from the two positive pulses or sparks of a four-cycle magneto ignition system can yield about one amp of current.","Other types of ignition systems also provide waste energy that could be harvested to power the electronic governor system.","In a four-cycle magneto ignition system there is a waste spark on the exhaust stroke of the cylinder.","In such a system, the two positive pulses or sparks and the waste negative pulse or spark could all be harvested.","In some embodiments, other power supplies that do not include a separate or dedicated power supply (e.g., a separate battery) may be used to power the motor 115 and/or the controller 155.Alternative power supplies include an alternator driven by the engine 105, a thermoelectric power generator that makes use of waste heat from the engine 105, a piezoelectric power generator driven by vibrations of the engine 105 and/or the outdoor power equipment driven by the engine 105, a Faraday power generator including a magnet oscillating within a coil driven in sync with the reciprocating movement of the piston of the engine 105.In some embodiments, an energy storage device (e.g., a rechargeable battery, a capacitor, etc.)","is provided to store the energy produced by the power supplies described above.","In this way, power is available for the motor 115 and/or the controller 155 when the engine 105 is initially started and there is not an immediately available supply of energy to be harvested from the operating engine 105.A rev limiter 185 may be provided to prevent the engine 105 from achieving an overspeed condition in which the engine speed exceeds a threshold (e.g., a redline).","The rev limiter 185 detects the engine speed and when the engine speed exceeds the threshold, shorts the ignition to prevent the engine from continuing to exceed the speed threshold.","To make the reduction in speed associated with shorting the ignition smoother (e.g., less sudden and/or less noisy to the operator), it may be preferable to short a subset of the ignition sparks rather than all of the engine sparks.","Shorting all of the ignition events (e.g., sparks associated with combustion events) would have an audible effect and the engine speed would abruptly drop.","Shorting fewer than 100% of the ignition events (e.g., every second, third, fourth, etc.","ignition event) would slow the engine speed but be less abrupt and less noticeable audibly to the user.","A user interface 165 may be provided so that the user is able to control the desired speed (e.g., expected or targeted speed) of the engine 105.This user interface 165 could be an analog input such as a voltage divider, a fixed resistor, a variable resister (e.g., a potentiometer or sliding variable resistor).","In some embodiments where the engine was used to power a wheel drive train (e.g., on a riding or walk behind lawn mower or snow thrower) a throttle input (e.g., a gas pedal or lever) may be moved to adjust the analog input and therefore adjust the desired speed of the engine.","If the engine is used to power a generator, a discreet two-position analog input could be used to switch the output frequency of the electricity provided by the generator between the 60 Hz electricity used in the United States and Canada, and the 50 Hz electricity used elsewhere in the rest of the world (e.g., Europe and Asia).","Other discreet control modes, for example, could include a quiet operating mode versus a power operating mode.","The quiet operating mode may be configured so that the engine runs at a relatively low speed (e.g., 2,400 rpm) versus the power mode which runs at a relatively high rpm (e.g., 3,000 rpm).","In some embodiments, the user interface is wireless RF, infrared IR, and LED or light pulse interface or capacitive sensing interface (e.g., a touchscreen).","In some embodiments the user interface 165 includes a second microcontroller.","For example, a touch screen or other interface device could provide inputs to a second controller which provide a variable voltage output to the controller operating the electronic governor system.","In some embodiments, the user interface 165 provides a digital input.","Initial performance characteristics of the engine governor system 100 can also be varied (e.g., more or less aggressive engine speed error correction.","These characteristic settings could be preset when the system or engine is assembled (e.g., by setting a specific resistance or voltage value).","For example one setting could be used with relatively low inertia equipment driven by the engine (e.g., the pump of a pressure washer) and a second setting could be used with relatively high inertia equipment driven by the engine (e.g., the blade of a lawn mower).","This provides the controller 155 with some initial performance characteristics (e.g., the relative inertia of the equipment being driven) before it has even had a chance to start adapting the control parameters based on the actual use of the engine.","For example, 1000-4000 rpm could be selected with input resistances of 100-400 ohms and with input resistances of 1100-1400 ohms with settings of 100-400 ohms providing moderately aggressive performance for relative low inertia applications and 1100-1400 ohms providing more aggressive performance for relatively high inertia applications.","Additionally, there could also be more than two performance characteristics settings (e.g., low inertia, moderately low inertia, moderate inertia, moderately high inertia, high inertia, etc.)","that could be selected based on engine type (e.g., size, number of cylinders, rated horsepower, rated torque) and equipment to be driven by the engine.","Alternatively, the performance characteristic settings could be tied to the voltages that will be read by the controller 155.A current sensor 175 may be included to monitor the current draw on the motor 115.For example, a shunt resistor may be used to measure this motor current.","The current sensor 175 is used to detect potential failures in the electronic governor system 100 and shut down the engine 105 (e.g., stop the engine) in response to detecting such a failure.","For example, a detected current above a high current threshold could indicate a jam, obstruction, the end of travel, a motor short, or some other situation in which the motor 115, the transmission 120, the throttle plate 125, the throttle lever 130, the linkage 135, or other movable component is unable to move (e.g., rotate, translate, etc.)","as desired.","When the current sensor 175 detects a current below a low current threshold this could indicate a broken wire or some other loss of electrical communication between the components of the electronic governor system 100.Both a high current above the high threshold and a low current below the low threshold may be indicative of situations in which the engine 105 should be stopped or shut down to prevent possible damage to the engine.","Engine shutdown module 230 is configured to shut down, stop, turn off, or deactivate the engine in response to an appropriate input (e.g., release of a safety interlock, like when the bail of a walk-behind lawn mower is released, movement of an on/off switch to the off position, etc.).","Engine shutdown module 230 may receive an input from the current sensor 172 and shut off the engine in response to low current or high current as described above.","In some embodiments, the engine speed sensor 160 detects the engine speed using an ignition signal from the ignition system 180.For example, the positive sparks or pulses from the ignition system could be counted and used to determine the engine speed.","This method of determining engine speed provides an additional advantage when shorting the negative pulses or sparks with the rev limiter 185.The engine speed detection, which is determined from the positive pulses, is not lost when slowing down the engine 105 with the rev limiter 185 by shorting the negative pulses or sparks.","In other embodiments, other appropriate engine speed sensors are utilized.","The electronic governor systems described herein are able to adjust the operating speed of the engine in response to an input from a load sensing system.","Combining a load sensing system with the electronic governor systems allows the operating speed of the engine to be optimized for various load conditions.","For example, an engine including an electronic governor system and a load sensing system as described herein could operate in one of two modes: a no load or low load mode (e.g., when the blade of a lawn mower is not cutting any grass) where the engine operates at an idle or relatively low speed and a high load mode (e.g., when the blade of the lawn mower is cutting grass) where the engine operates at an high operating or relatively high speed.","More complex systems allow for additional modes of operation for example a moderate load mode (e.g., when the blade of the lawn mower is cutting grass that is thinner than that being cut in the high load mode) where the engine operates at a speed between the idle speed and the high operating speed.","The engine speed could also vary continuously with load or approximately continuously with load (e.g., with a step-function or other appropriate curve fit).","For example, the engine speed could be controlled to always fit within a band or window defined by a high engine speed curve and a low engine speed curve and operate in a manner similar to a continuously variable transmission.","The load sensing system makes use of the principle of rotational motion that the sum of the torques for the system equals zero.","The sum of the torques is equal to inertia times the change in angular velocity as shown in the equation below.","The TorqueProduced is the torque produced from combustion by the engine and the TorqueLoad/Losses is the torque produced from the load on the engine (e.g., mower blade, pressure washer pump, drive system, etc.)","and any losses within the engine (e.g., friction, gas compression, vacuum, etc.)","J{umlaut over (θ)}=TorqueProduced−TorqueLoad/Losses In a first load sensing system for a single cylinder four-cycle engine, the load can be estimated by comparing the rotational speed of the engine for two consecutive engine revolutions.","A “fast” revolution occurs during the expansion and exhaust cycles of the engine.","A “slow” revolution occurs during the intake and compression cycles of the engine.","The difference in revolution speed (e.g., in revolutions per minute (“RPM”)) is a function of the TorqueLoad/Losses and inertia.","When the inertia is known (e.g., the inertia of a specific end use of the engine, for example for a specific lawn mower, pressure washer, tractor, or other piece of outdoor power equipment), then the difference in revolution speed from the fast revolution to the slow revolution (e.g., RPM of the fast revolution minus the RPM of the slow revolution) is a function of the TorqueLoad/Losses.","By calculating this difference, the load sensing system can accurately estimate the load on the engine.","The load can then be used as an input to the electronic governing system to control the speed of the engine.","In a second load sensing system for a single cylinder four-cycle engine, the load can be estimated by comparing the rotational speed of the engine for each of the four cycles.","The sum of the torques for each of the four cycles (expansion, compression, intake, and compression) can be calculated according to the equation shown below.","J{umlaut over (θ)}=TorqueProduced−TorqueLoss−TorqueLoad Using four versions of this equation, one for each cycle, with the inertia remaining constant for all four equations, the load sensing system is able to determine the load based on the measured change in engine speed from one cycle to the next because each of the four equations is left with only one unknown (four equations with four unknowns are solvable).","For the expansion cycle, TorqueLoss is negligible and can be assumed to be zero.","For the exhaust cycle, TorqueProduced and TorqueLoss are negligible and can be assumed to be zero.","For the intake cycle, TorqueProduced and TorqueLoss are negligible and can be assumed to be zero.","For the compression cycle, TorqueProduced is negligible and can be assumed to be zero.","The combustion process can vary from combustion cycle.","The combustion process regularly experiences “bumps” or “pops” due to many possible factors including fuel quality, air availability, variations in the fuel-air ration, etc.","Either of the two load sensing systems described above can reduce the impact of these combustion process variations, which may result in variations of the engine speed, which is the inputs to the calculations used to determine the load for both systems, by using a running average and/or a standard deviation of the engine speed measurements.","The average load value can be calculated using the equation below.","“A” is a factor used to weigh the average load value.","The value of A may be selected based on the intended end use of the engine (e.g., lawn mower, pressure washer, tractor, or other piece of outdoor power equipment) and the desired engine performance for that engine.","As the value of A increases, the average load value becomes smoother, but it delays response time for true changes in load, rather than momentary chances due to combustion variations.","Avg ."," Load Value = ( Avg ."," Load Value * A + New Load Value ) A + 1 The average load value can be used as the trigger to change between operating modes of the electronic governing system.","For example for the two operating mode electronic governing system discussed above, the no load operating mode can be triggered when the average load value is at or below a predetermined threshold value and the high load operating mode can be triggered when the average load value is at or above a predetermined threshold value.","To avoid hunting or hysteresis between the two modes, the predetermined threshold values can be different for the no load operating mode and the high load operating mode.","For example, the no load threshold value could be an average load value of 15 and the high load threshold value could be 20, providing a window between 15 and 20 where mode hunting is avoided.","Alternatively a percentage change threshold (e.g., 20%) in average load value could be used as the trigger to change between operating modes of the electronic governing system.","The threshold values, whether absolute or a percentage, can be tied to specific engine sizes and end products.","Another way to avoid mode hunting is to include a minimum predetermined time period between operating mode changes.","For example, each operating mode could be required to run for at least 5 seconds before be able to switch based on the current average load value.","A standard deviation of the load value could be used in similar manners on its own or in combination with the average load value to provide a trigger to change between operating modes of the electronic governing system.","The standard deviation of the measured engine speed may also be used to distinguish between an actual change in engine speed (e.g., due to an increased or decreased load on the engine) and intermittent variations in engine speed due to combustion irregularities.","Measured engine speed includes expected variations on a per-cycle basis.","The expansion (combustion, power) cycle has a faster engine speed than the intake, compression, and exhaust cycles.","The standard deviation accounts for the expected variations on a per-cycle basis so that only engine speed changes in excess of the standard deviation, or in excess of the standard deviation modified by an error factor (e.g., multiplied or added to the standard deviation), are used to trigger a change in throttle plate position by the engine governing system.","Both load sensing systems make use of an appropriate controller to implement the control schemes discussed above and of an appropriate engine speed sensor to detect the engine speed for use as an input as discussed above.","Possible engine speed sensors include a magnetic field sensor (e.g., a Hall Effect sensor or reed switch) in combination with a magnet on the flywheel.","The magnet on the flywheel could be the same used to generate the spark for the ignition system, but could also be a separate second magnet.","Both load sensing systems could also include an operating mode input to provide a verification that the detected change in load based on the engine speed calculations as an intended change in load based on the user's intended operating mode.","For example, a tilt sensor could indicate when the front wheels of a walk behind lawn mower are lifted off the ground, thereby confirming a reduced load.","A switch on the bail of walk behind lawn mower could indicate when the operator engages the drive system.","A vacuum sensor could detect changes in engine vacuum as a redundant check on load changes.","A user-actuated switch could also be used as a feedforward input to the load sensing system.","For example, a switch actuated by a user operated lever (e.g., the bail of a walk-behind mower, the trigger of a pressure washer spray gun, a control lever of a snowthrower, a power takeoff engage switch on a riding tractor, etc.)","would indicate an expected engine load to the load sensing system (e.g., operation of the tool driven by the engine, a load on the tool driven by the engine, engagement of a drive train, etc.).","The load sensing system could use this feedforward input to override or supplement the load output provided by the load sensing system.","The same controller or separate controllers can be used to implement the controls schemes used by the electronic governor system and by the load sensing system.","For example, as shown in FIG.","2, the controller 155 could be used to control both the electronic governor system 100 and a load sensing system as described above via a load sensing module 235 configured to implement a load sensing system as described herein.","The engine speed sensor 160 could be used to provide the necessary engine speed inputs to the load sensing module 235 to implement the load sensing system.","The

methodology set forth in the description or illustrated in the figures.\",\n \"It should also be understood that the terminology is for the purpose of description only and should not be regarded as limiting.\",\n \"Referring to FIGS.\",\n \"1-2 and 4-5, an electronic governor system is illustrated according to an exemplary embodiment.\",\n \"The electronic governor system 100 is shown in use on a small engine 105.The electronic governor system 100 includes a carburetor 110, a motor 115 (e.g., a direct current (“DC”) motor), a transmission 120, a throttle plate 125, a throttle lever 130 and a linkage 135 connecting the throttle lever to the transmission.\",\n \"In the carburetor 110, fuel is mixed with air to produce an air/fuel mixture for combustion in one or more cylinders of the engine 105.The throttle plate 125 controls the flow of the air/fuel mixture out of the carburetor 110 and in doing so controls the speed of the engine 105.As illustrated, the linkage 135 includes a link 140 and a crank arm 145.In some embodiments the electronic governor system 100 also includes an encoder 150 that is coupled to the motor 115 and the transmission 120.The motor assembly (i.e., the motor 115 and the transmission 120) is used to control the position of the throttle plate 125, thereby controlling the engine speed.\",\n \"The throttle plate 125 is movable between a closed position and a wide-open position.\",\n \"The position of the throttle plate 125 is adjusted so that the engine speed is maintained at a desired engine speed.\",\n \"The desired engine speed can be a constant or can be varied by a user or a controller in response to inputs from the engine (e.g., inputs related to engine load, desired output, or other engine operating conditions or objectives).\",\n \"The motor 115 is relatively low cost, particularly with respect to the stepper motor typically used in other electronic governor systems.\",\n \"The motor 115 does not track steps of the motor's rotation like a stepper motor.\",\n \"In some embodiments, the motor 115 is a brushed motor.\",\n \"The transmission 120 provides a large reduction ratio (i.e., input speed/output speed).\",\n \"For example, the motor 115 may have a top speed of 4,000 revolutions per minute (rpm).\",\n \"The transmission 120 may provide a reduction so that the output from the transmission turns at 100 rpm (i.e., a 40:1 reduction ratio).\",\n \"This will result in a transmission output speed that is relatively fast as compared to the amount of rotation necessary to adjust the throttle plate position (e.g., 75 to 100 rpm), with the throttle plate's range of motion (i.e., between the closed position and the wide-open position) being less than a full revolution, and produces a relatively large amount of torque.\",\n \"At this relatively fast transmission output speed the throttle plate 125 is able to move from closed to wide open in about 40 milliseconds.\",\n \"As another example, the motor 115 may have an output speed of at about 10,000 rpm and the transmission may provide a gear reduction such that the output of the transmission is about 60 rpm (i.e.\",\n \"a reduction ratio of about 167:1).\",\n \"In some embodiments, the transmission 120 is a series of gears that provides a reduction from the input of the motor to the output of the transmission.\",\n \"The transmission 120 providing a large reduction ratio produces an output from the transmission 120 with a relatively large amount of torque.\",\n \"The output shaft of the transmission 120 only needs to rotate a small amount to adjust the throttle plate position within the throttle plate's range of motion and in doing so is able to produce a lot of torque.\",\n \"Another advantage of this large reduction ratio is that power only needs to be supplied to the motor 115 when moving the output shaft of the transmission 120 to the desired position.\",\n \"This position corresponds with the desired position of the throttle plate 125.After the output shaft of the transmission 120, and therefore the throttle plate 125, has reached the desired position, the motor 115 is no longer powered (i.e., the motor 115 is turned off).\",\n \"In this way, power is not needed to maintain the position of the output shaft of the transmission 120 and of the throttle plate 125.The relatively large reduction ratio provided by the transmission 120 is able to maintain or hold the throttle plate 125 in position without power being supplied to the motor 115 to maintain the desired position of the throttle plate 125.In some embodiments several components of the electronic governor system 100 are included within a single housing.\",\n \"For example, the motor 115 and the transmission 120 could form a single unit.\",\n \"This unit may be combined with the controller 155 and its associated circuit board.\",\n \"As shown in FIG.\",\n \"1, the linkage 135 connects the output shaft of the transmission 120 to the throttle lever 130.The throttle lever 130 is connected to the throttle plate 125, such that the motor 115 drives the transmission 120 which moves the linkage 135 which moves the throttle lever 130 which moves the throttle plate 125.In this way, powering the motor 115 causes the throttle plate 125 to change position.\",\n \"Though the linkage 135 is shown as a two-piece linkage, other appropriate mechanisms for connecting the output shaft of the transmission 120 to the throttle plate 125 may be utilized.\",\n \"For example, the output shaft of the transmission 120 could be directly connected to the throttle plate 125 or one or more components could be used to connect the output shaft of the transmission 120 to the throttle plate 125.In some embodiments, one or more gears are used to connect the output shaft of the transmission 120 to the throttle plate 125.In some embodiments, the encoder 150 is connected to the motor 115 and the transmission 120 to determine the position of the output shaft of the transmission 120.In some embodiments, the encoder 150 is an absolute encoder and can be used to keep track of the position of the output shaft of the transmission 120 and therefore the position of the throttle plate 125.As shown in FIG.\",\n \"2, the electronic governor system 100 includes a controller 155 that controls the operation of the motor 115.In some embodiments, the controller 155 also controls the operation of other components of the electronic governor system 100 that will be described in more detail below.\",\n \"These components may include an engine speed sensor 160, a user interface 165, a temperature sensor 170, a current sensor 175, an ignition system 180, and a rev limiter 185.Different embodiments of the electronic governor system 100 may include some, none or all of these additional components.\",\n \"As shown in FIG.\",\n \"3, the controller 155 includes a processing circuit 190, an input interface 195, and an output interface 200.The processing circuit 190 includes a processor 205 and memory 210.The processing circuit 190 and processor 205 are configured to receive inputs from input interface 195 (e.g., via a wired or wireless communication link with other components of the engine and/or electronic governor system) and to provide an output (e.g., a control signal, an actuator output, etc.)\",\n \"via output interface 200 (e.g., via a wired or wireless communication link to the motor 115, other components of the engine, and/or other components of the electronic governor system).\",\n \"The processing circuit 190 can be a circuit containing one or more processing components (e.g., the processor 205) or a group of distributed processing components.\",\n \"The processor 205 may be a general purpose or specific purpose processor configured to execute computer code or instructions stored in the memory or received from other computer readable media (e.g., CD-ROM, network storage, a remote server, etc.).\",\n \"The processing circuit 190 is also shown to include the memory 210.Memory 210 may be RAM, hard drive storage, temporary storage, non-volatile memory, flash memory, optical memory, or any other suitable memory for storing software objects and/or computer instructions.\",\n \"When the processor 205 executes instructions stored in the memory 210 for completing the various activities described herein, the processor 205 generally configures the computer system and more particularly the processing circuit 190 to complete such activities.\",\n \"The memory 210 may include database components, object code components, script components, and/or any other type of information structure for supporting the various activities described in the present disclosure.\",\n \"For example, the memory 210 may store data regarding the operation of a controller (e.g., previous setpoints, previous behavior patterns regarding used energy to adjust a current value to a setpoint, etc.).\",\n \"According to an exemplary embodiment, the memory 210 is communicably connected to the processor 205 and includes computer code for executing one or more processes described herein and the processor 205 is configured to execute the computer code.\",\n \"The memory 210 is shown to include a feedback control module 215 and an adaptive control module 220.The memory may include a throttle plate position module 225 and an engine shutdown module 230.The feedback control module 215 is the primary logic module configured to provide the feedback-based control activity of the controller 155.In some embodiments, the feedback control module 215 is a proportional-integral-derivative (PID) control module.\",\n \"In other embodiments, the feedback control module 215 is a fuzzy logic control module.\",\n \"The feedback control module 215 uses information from the input interface 195 (e.g., detected engine speed) to calculate or otherwise obtain the controlled variable (e.g., throttle plate position).\",\n \"The feedback control module 215 may also use information stored in the memory 210 (e.g., previous detected engine speed, desired engine speed, etc.)\",\n \"in calculating or obtaining the controlled variable.\",\n \"The adaptive control module 220 is configured to determine appropriate values of control parameters (e.g., proportional gain, integral gain, derivative gain, etc.).\",\n \"The adaptive control module 220 may tune control parameters based on a model identification adaptive control (MIAC) approach or another adaptive tuning approach or algorithm.\",\n \"The feedback control module 215 is configured to provide an engine speed control output based an engine speed error determined by a comparison of a current engine speed input from the engine speed sensor 160 with the desired engine speed.\",\n \"The output is provided to the motor 115 to adjust the throttle plate 125 position, thereby controlling the engine speed and correcting any engine speed error so that the detected engine speed and the desired engine speed are the same or substantially the same (e.g., within a predetermined range).\",\n \"The feedback control module can use different types of feedback control including PID control algorithms or fuzzy logic control rules.\",\n \"The adaptive control module 220 adjusts one or more parameters (e.g., coefficients, gains, rules, etc.)\",\n \"of the feedback control module 215 such that the feedback control module learns the appropriate operating parameters for a specific engine and end product (e.g., lawn mower, snow thrower, generator, pressure washer, etc.).\",\n \"For example, the feedback control module 215 may determine an engine speed error and provide an engine speed output intended to correct that error or a portion of the error (e.g., reduce the error by half).\",\n \"The adaptive control module 220 determines what an expected engine speed error correction is based on the output provided by the feedback control module 215.The adaptive control module 220 also determines an actual engine speed correction based on the current engine speed input from the engine speed sensor 160 and a previous engine speed input from the engine speed sensor 160.The adaptive control module 220 then is able to determine a correction error based on the expected engine speed error and the actual engine speed correction.\",\n \"In this way, the adaptive control module 220 is able to determine if the actual engine speed correction is the same as or close to the expected engine speed error correction (e.g., determine a correction error).\",\n \"If the actual engine speed correction is not the same (or within a predetermined range acceptable as the same) as the expected engine speed correction, the adaptive control module 220 adjusts one or more parameters of the feedback control module 215.When the actual engine speed error correction was less than the expected engine error correction the parameter change is such that the subsequent attempt at correcting engine speed will be more aggressive.\",\n \"As used herein, more aggressive means that the position change of the throttle plate with adjusted parameter setting will be greater than at the previous parameter setting and less aggressive means that the position change of the throttle plate with adjusted parameter setting will be less than at the previous parameter setting.\",\n \"For example, in a controller 155 using PID control the adaptive control module 220 can change one or more of the proportional, integral and derivative parameters (e.g., coefficients or gains) of the feedback control module 215 to achieve the desired change in engine speed.\",\n \"The PID control of the feedback control module 215 may set forth a control algorithm to determine the motor adjustment—the amount of time voltage is supplied to the motor 115 (the duration or “width” of a voltage pulse).\",\n \"For example, the PID control algorithm may use the following equation to determine the motor adjustment where Error is the engine speed error.\",\n \"Motor Adjustment = P i Error + D i d Error dt + I i ∫ Error The adaptive control module 220 may be configured to adjust one or more of the proportional, integral and derivative parameters in response to a comparison of the actual change in engine speed following a throttle plate position adjustment (e.g., as measured by the engine speed sensor 160) with the expected change in engine speed following a throttle plate position adjustment (e.g., the engine speed error or a portion (e.g., one half, one third, etc.)\",\n \"of the engine speed error).\",\n \"If the actual change in engine speed is less than the expected change in engine speed, one or more of the parameters is adjusted to make the motor adjustment more aggressive (i.e., provide a voltage pulse of a longer duration).\",\n \"If the actual change in engine speed is greater than the expected change in engine speed, one or more of the parameters is adjusted to make the motor adjustment less aggressive (i.e., provide a voltage pulse of a shorter duration).\",\n \"The comparison of actual change in engine speed to the expected change in engine speed can be performed at a specific time (e.g., 2-3 engine cycles) after a motor adjustment pulse is sent to the motor 115.In some embodiments, the pulse of the motor adjustment has a duty cycle and the duty cycle of the pulse of the motor adjustment may be adjusted when the actual change in engine speed is different than the expected change in engine speed.\",\n \"In some embodiments, the motor adjustment algorithm In some embodiments using a PID control algorithm there are multiple parameter sets.\",\n \"For example, a first parameter set may be used when the throttle plate 125 is close or near to the closed position and a second parameter set may be used when the throttle plate 125 is close or near to the wide open position.\",\n \"This is helpful because the operating performance (e.g., speed) of the engine is not linear with respect to throttle plate position.\",\n \"When the throttle plate 125 is near the wide open position, the engine speed is not very responsive to changes in the throttle plate position and when the throttle plate 125 is near the closed position, the engine speed is more responsive to changes in the throttle plate position.\",\n \"Therefore, the parameter set associated with operation when the throttle plate 125 is near the closed position would be less aggressive than the parameter set that is used when the throttle plate 125 is near the wide open position.\",\n \"Two or more parameter sets based on the throttle position could be implemented.\",\n \"For example a curve could be fit so that the parameter sets used change from the closed position to the wide open position.\",\n \"The adaptive control module 220 may also be configured to perform a comparison of the expected output (i.e., rotational speed) of the motor 115 from a particular duration of applied voltage (voltage pulse) to the back electromotive force (“back-EMF”) actually caused by that particular duration of applied voltage.\",\n \"Back-EMF is caused by the rotation of the motor and can act as a proxy for a motor sensor for detecting the rotational speed of the motor.\",\n \"In this way the adaptive control module 220 allows the system to learn or adjust to the operational characteristics of a particular engine.\",\n \"Variations among particular engines (e.g., individual DC motors, the end use of the engine, etc.)\",\n \"will result in different duration voltage pulses being necessary to move a throttle plate a specific amount.\",\n \"For example, in one engine a voltage pulse of 10 milliseconds may move the throttle plate 10 degrees, but may only move the throttle plate of a second engine 5 degrees.\",\n \"The back-EMF correlation performed by the adaptive control module 220 allows the system to learn the particular voltage pulse duration needed for a particular throttle plate position change within the addition of a motor speed sensor and allows for that correlation to change as engine performance changes over the life of a particular engine.\",\n \"The back-EMF comparison can also be used to determine when the throttle plate 125 is at either end of its range of motion (i.e., closed position or wide open position) because the throttle plate 125 is at a hard stop at either end of its range of motion and the back-EMF should approach zero as the motor is unable to turn.\",\n \"The back-EMF comparison can also be used to identify variations between the operational characteristics of individual motors and a curve establishing a known or desired relationship between back-EMF and engine speed (e.g., RPM) and to determine the operational characteristics that need to be modified (e.g., duration of voltage pulses) to fit a specific motor to the known back-EMF and engine speed curve.\",\n \"As shown in FIGS.\",\n \"6-7, in some embodiments of the electronic governor system 100, an elliptical gear set 186 is included between the transmission 120 and the throttle lever 130 to account for the non-linearity of engine speed with respect to throttle plate position.\",\n \"The elliptical gear set 186 includes two elliptical gears—a driving gear 187 and a driven gear 188.The driving gear 187 has a minor radius 189 that is less than a major radius 191.The driving gear 187 is coupled to or a component of the transmission 120.The driven gear 188 is coupled to the throttle plate 125 (e.g., directly or indirectly by one or more links or gears).\",\n \"The driven gear 188 has a minor radius 192 that is less than a major radius 193.The elliptical gear set 186 is arranged so that the driven gear 188 provides a relatively large amount of movement of the throttle plate 125 in response to specified amount of movement of the driving gear 187 when the throttle plate 125 is near the wide open position (FIG.\",\n \"6) and so that the driven gear 188 provides a relatively small amount of movement of the throttle plate 125 in response to the same specified amount of movement of the driving gear 187 when the throttle plate 125 is near the closed position (FIG.\",\n \"7).\",\n \"As shown in FIG.\",\n \"6, when the throttle plate 125 is near the wide open position, the major radius 191 of the driving gear 187 engages the minor radius 192 of the driven gear 188.As shown in FIG.\",\n \"7, when the throttle plate 125 is near the closed position, the minor radius 189 of the driving gear 187 engages the major radius 193 of the driven gear 188.In embodiments where the feedback control module 215 uses a fuzzy logic control algorithm to control the output to the motor 115, a list of fuzzy logic rules is created to control the operation of the motor 115.These rules allow for non-linear control of the non-linear engine operation.\",\n \"In some embodiments, the temperature sensor 170 provides the detected temperature as an input to the fuzzy logic rule set.\",\n \"In some embodiments the electronic governor system 100 includes a temperature sensor 170.The temperature sensor 170 is configured to detect a temperature (e.g., an ambient temperature, an engine temperature, or other appropriate temperature).\",\n \"The detected temperature is provided as an input to the controller 155 and may be utilized as an input to the various logic modules of the controller 155.As the engine may operate differently as relatively cold temperatures and relatively hot temperatures different control parameters (e.g., of the feedback control module 215 and/or the adaptive control module 220) can be used when the detected temperature is either below or above one or more thresholds (e.g.\",\n \"a hot operating condition threshold and a cold operating condition threshold).\",\n \"The memory 210 may also include a throttle plate position module 225.The throttle plate position module 225 is configured to determine the position of the throttle plate 125 based on tracking the expected changes in the throttle plate position from an initial throttle plate position.\",\n \"The initial throttle plate position is known.\",\n \"For example, the wide open position may be considered to be 90° and the closed position may be considered to be 0°.\",\n \"Based on that starting position (e.g., the wide open position), the throttle plate position module 225 calculates a current throttle plate position based on the changes to the throttle plate position caused by the motor 115.The product of the voltage applied to the motor 115 and the amount of time for which that voltage is supplied corresponds to an expected change in the position of the throttle plate 125.By keeping track of all expected movements of the throttle plate 125 from the initial known position caused by operation of the motor 115, the throttle plate position module 225 is able to track the position of the throttle plate 125.Alternatively, an encoder (e.g., the encoder 150) may keep track of the throttle plate position.\",\n \"However, an encoder adds cost that may not be necessary for the electronic governor system 100 to operate as desired.\",\n \"The engine 105 includes an ignition system 180.In some embodiments excess energy from the ignition system 180 is used to power the motor 115 and/or the controller 155.In this way the electronic governor system 100 is able to operate without a separate or dedicated power supply (e.g., a separate battery or the battery used to power an electric engine starting system).\",\n \"In a magneto or spark ignition system extra energy in the form of ignition sparks or pulses can be harvested and stored in a capacitor or other energy storage device (e.g., battery) for use to power the motor 115.Though a spark based ignition system is discussed as an example other types of ignition systems are possible.\",\n \"The excess energy of the ignition system may also be sufficient to power the motor 115 and/or the controller 155.After the engine 105 is started, there is a relatively abundant amount of excess energy that can be harvested to power the electronic governor system 100.For example, the energy from the two positive pulses or sparks of a four-cycle magneto ignition system can yield about one amp of current.\",\n \"Other types of ignition systems also provide waste energy that could be harvested to power the electronic governor system.\",\n \"In a four-cycle magneto ignition system there is a waste spark on the exhaust stroke of the cylinder.\",\n \"In such a system, the two positive pulses or sparks and the waste negative pulse or spark could all be harvested.\",\n \"In some embodiments, other power supplies that do not include a separate or dedicated power supply (e.g., a separate battery) may be used to power the motor 115 and/or the controller 155.Alternative power supplies include an alternator driven by the engine 105, a thermoelectric power generator that makes use of waste heat from the engine 105, a piezoelectric power generator driven by vibrations of the engine 105 and/or the outdoor power equipment driven by the engine 105, a Faraday power generator including a magnet oscillating within a coil driven in sync with the reciprocating movement of the piston of the engine 105.In some embodiments, an energy storage device (e.g., a rechargeable battery, a capacitor, etc.)\",\n \"is provided to store the energy produced by the power supplies described above.\",\n \"In this way, power is available for the motor 115 and/or the controller 155 when the engine 105 is initially started and there is not an immediately available supply of energy to be harvested from the operating engine 105.A rev limiter 185 may be provided to prevent the engine 105 from achieving an overspeed condition in which the engine speed exceeds a threshold (e.g., a redline).\",\n \"The rev limiter 185 detects the engine speed and when the engine speed exceeds the threshold, shorts the ignition to prevent the engine from continuing to exceed the speed threshold.\",\n \"To make the reduction in speed associated with shorting the ignition smoother (e.g., less sudden and/or less noisy to the operator), it may be preferable to short a subset of the ignition sparks rather than all of the engine sparks.\",\n \"Shorting all of the ignition events (e.g., sparks associated with combustion events) would have an audible effect and the engine speed would abruptly drop.\",\n \"Shorting fewer than 100% of the ignition events (e.g., every second, third, fourth, etc.\",\n \"ignition event) would slow the engine speed but be less abrupt and less noticeable audibly to the user.\",\n \"A user interface 165 may be provided so that the user is able to control the desired speed (e.g., expected or targeted speed) of the engine 105.This user interface 165 could be an analog input such as a voltage divider, a fixed resistor, a variable resister (e.g., a potentiometer or sliding variable resistor).\",\n \"In some embodiments where the engine was used to power a wheel drive train (e.g., on a riding or walk behind lawn mower or snow thrower) a throttle input (e.g., a gas pedal or lever) may be moved to adjust the analog input and therefore adjust the desired speed of the engine.\",\n \"If the engine is used to power a generator, a discreet two-position analog input could be used to switch the output frequency of the electricity provided by the generator between the 60 Hz electricity used in the United States and Canada, and the 50 Hz electricity used elsewhere in the rest of the world (e.g., Europe and Asia).\",\n \"Other discreet control modes, for example, could include a quiet operating mode versus a power operating mode.\",\n \"The quiet operating mode may be configured so that the engine runs at a relatively low speed (e.g., 2,400 rpm) versus the power mode which runs at a relatively high rpm (e.g., 3,000 rpm).\",\n \"In some embodiments, the user interface is wireless RF, infrared IR, and LED or light pulse interface or capacitive sensing interface (e.g., a touchscreen).\",\n \"In some embodiments the user interface 165 includes a second microcontroller.\",\n \"For example, a touch screen or other interface device could provide inputs to a second controller which provide a variable voltage output to the controller operating the electronic governor system.\",\n \"In some embodiments, the user interface 165 provides a digital input.\",\n \"Initial performance characteristics of the engine governor system 100 can also be varied (e.g., more or less aggressive engine speed error correction.\",\n \"These characteristic settings could be preset when the system or engine is assembled (e.g., by setting a specific resistance or voltage value).\",\n \"For example one setting could be used with relatively low inertia equipment driven by the engine (e.g., the pump of a pressure washer) and a second setting could be used with relatively high inertia equipment driven by the engine (e.g., the blade of a lawn mower).\",\n \"This provides the controller 155 with some initial performance characteristics (e.g., the relative inertia of the equipment being driven) before it has even had a chance to start adapting the control parameters based on the actual use of the engine.\",\n \"For example, 1000-4000 rpm could be selected with input resistances of 100-400 ohms and with input resistances of 1100-1400 ohms with settings of 100-400 ohms providing moderately aggressive performance for relative low inertia applications and 1100-1400 ohms providing more aggressive performance for relatively high inertia applications.\",\n \"Additionally, there could also be more than two performance characteristics settings (e.g., low inertia, moderately low inertia, moderate inertia, moderately high inertia, high inertia, etc.)\",\n \"that could be selected based on engine type (e.g., size, number of cylinders, rated horsepower, rated torque) and equipment to be driven by the engine.\",\n \"Alternatively, the performance characteristic settings could be tied to the voltages that will be read by the controller 155.A current sensor 175 may be included to monitor the current draw on the motor 115.For example, a shunt resistor may be used to measure this motor current.\",\n \"The current sensor 175 is used to detect potential failures in the electronic governor system 100 and shut down the engine 105 (e.g., stop the engine) in response to detecting such a failure.\",\n \"For example, a detected current above a high current threshold could indicate a jam, obstruction, the end of travel, a motor short, or some other situation in which the motor 115, the transmission 120, the throttle plate 125, the throttle lever 130, the linkage 135, or other movable component is unable to move (e.g., rotate, translate, etc.)\",\n \"as desired.\",\n \"When the current sensor 175 detects a current below a low current threshold this could indicate a broken wire or some other loss of electrical communication between the components of the electronic governor system 100.Both a high current above the high threshold and a low current below the low threshold may be indicative of situations in which the engine 105 should be stopped or shut down to prevent possible damage to the engine.\",\n \"Engine shutdown module 230 is configured to shut down, stop, turn off, or deactivate the engine in response to an appropriate input (e.g., release of a safety interlock, like when the bail of a walk-behind lawn mower is released, movement of an on/off switch to the off position, etc.).\",\n \"Engine shutdown module 230 may receive an input from the current sensor 172 and shut off the engine in response to low current or high current as described above.\",\n \"In some embodiments, the engine speed sensor 160 detects the engine speed using an ignition signal from the ignition system 180.For example, the positive sparks or pulses from the ignition system could be counted and used to determine the engine speed.\",\n \"This method of determining engine speed provides an additional advantage when shorting the negative pulses or sparks with the rev limiter 185.The engine speed detection, which is determined from the positive pulses, is not lost when slowing down the engine 105 with the rev limiter 185 by shorting the negative pulses or sparks.\",\n \"In other embodiments, other appropriate engine speed sensors are utilized.\",\n \"The electronic governor systems described herein are able to adjust the operating speed of the engine in response to an input from a load sensing system.\",\n \"Combining a load sensing system with the electronic governor systems allows the operating speed of the engine to be optimized for various load conditions.\",\n \"For example, an engine including an electronic governor system and a load sensing system as described herein could operate in one of two modes: a no load or low load mode (e.g., when the blade of a lawn mower is not cutting any grass) where the engine operates at an idle or relatively low speed and a high load mode (e.g., when the blade of the lawn mower is cutting grass) where the engine operates at an high operating or relatively high speed.\",\n \"More complex systems allow for additional modes of operation for example a moderate load mode (e.g., when the blade of the lawn mower is cutting grass that is thinner than that being cut in the high load mode) where the engine operates at a speed between the idle speed and the high operating speed.\",\n \"The engine speed could also vary continuously with load or approximately continuously with load (e.g., with a step-function or other appropriate curve fit).\",\n \"For example, the engine speed could be controlled to always fit within a band or window defined by a high engine speed curve and a low engine speed curve and operate in a manner similar to a continuously variable transmission.\",\n \"The load sensing system makes use of the principle of rotational motion that the sum of the torques for the system equals zero.\",\n \"The sum of the torques is equal to inertia times the change in angular velocity as shown in the equation below.\",\n \"The TorqueProduced is the torque produced from combustion by the engine and the TorqueLoad/Losses is the torque produced from the load on the engine (e.g., mower blade, pressure washer pump, drive system, etc.)\",\n \"and any losses within the engine (e.g., friction, gas compression, vacuum, etc.)\",\n \"J{umlaut over (θ)}=TorqueProduced−TorqueLoad/Losses In a first load sensing system for a single cylinder four-cycle engine, the load can be estimated by comparing the rotational speed of the engine for two consecutive engine revolutions.\",\n \"A “fast” revolution occurs during the expansion and exhaust cycles of the engine.\",\n \"A “slow” revolution occurs during the intake and compression cycles of the engine.\",\n \"The difference in revolution speed (e.g., in revolutions per minute (“RPM”)) is a function of the TorqueLoad/Losses and inertia.\",\n \"When the inertia is known (e.g., the inertia of a specific end use of the engine, for example for a specific lawn mower, pressure washer, tractor, or other piece of outdoor power equipment), then the difference in revolution speed from the fast revolution to the slow revolution (e.g., RPM of the fast revolution minus the RPM of the slow revolution) is a function of the TorqueLoad/Losses.\",\n \"By calculating this difference, the load sensing system can accurately estimate the load on the engine.\",\n \"The load can then be used as an input to the electronic governing system to control the speed of the engine.\",\n \"In a second load sensing system for a single cylinder four-cycle engine, the load can be estimated by comparing the rotational speed of the engine for each of the four cycles.\",\n \"The sum of the torques for each of the four cycles (expansion, compression, intake, and compression) can be calculated according to the equation shown below.\",\n \"J{umlaut over (θ)}=TorqueProduced−TorqueLoss−TorqueLoad Using four versions of this equation, one for each cycle, with the inertia remaining constant for all four equations, the load sensing system is able to determine the load based on the measured change in engine speed from one cycle to the next because each of the four equations is left with only one unknown (four equations with four unknowns are solvable).\",\n \"For the expansion cycle, TorqueLoss is negligible and can be assumed to be zero.\",\n \"For the exhaust cycle, TorqueProduced and TorqueLoss are negligible and can be assumed to be zero.\",\n \"For the intake cycle, TorqueProduced and TorqueLoss are negligible and can be assumed to be zero.\",\n \"For the compression cycle, TorqueProduced is negligible and can be assumed to be zero.\",\n \"The combustion process can vary from combustion cycle.\",\n \"The combustion process regularly experiences “bumps” or “pops” due to many possible factors including fuel quality, air availability, variations in the fuel-air ration, etc.\",\n \"Either of the two load sensing systems described above can reduce the impact of these combustion process variations, which may result in variations of the engine speed, which is the inputs to the calculations used to determine the load for both systems, by using a running average and/or a standard deviation of the engine speed measurements.\",\n \"The average load value can be calculated using the equation below.\",\n \"“A” is a factor used to weigh the average load value.\",\n \"The value of A may be selected based on the intended end use of the engine (e.g., lawn mower, pressure washer, tractor, or other piece of outdoor power equipment) and the desired engine performance for that engine.\",\n \"As the value of A increases, the average load value becomes smoother, but it delays response time for true changes in load, rather than momentary chances due to combustion variations.\",\n \"Avg .\",\n \" Load Value = ( Avg .\",\n \" Load Value * A + New Load Value ) A + 1 The average load value can be used as the trigger to change between operating modes of the electronic governing system.\",\n \"For example for the two operating mode electronic governing system discussed above, the no load operating mode can be triggered when the average load value is at or below a predetermined threshold value and the high load operating mode can be triggered when the average load value is at or above a predetermined threshold value.\",\n \"To avoid hunting or hysteresis between the two modes, the predetermined threshold values can be different for the no load operating mode and the high load operating mode.\",\n \"For example, the no load threshold value could be an average load value of 15 and the high load threshold value could be 20, providing a window between 15 and 20 where mode hunting is avoided.\",\n \"Alternatively a percentage change threshold (e.g., 20%) in average load value could be used as the trigger to change between operating modes of the electronic governing system.\",\n \"The threshold values, whether absolute or a percentage, can be tied to specific engine sizes and end products.\",\n \"Another way to avoid mode hunting is to include a minimum predetermined time period between operating mode changes.\",\n \"For example, each operating mode could be required to run for at least 5 seconds before be able to switch based on the current average load value.\",\n \"A standard deviation of the load value could be used in similar manners on its own or in combination with the average load value to provide a trigger to change between operating modes of the electronic governing system.\",\n \"The standard deviation of the measured engine speed may also be used to distinguish between an actual change in engine speed (e.g., due to an increased or decreased load on the engine) and intermittent variations in engine speed due to combustion irregularities.\",\n \"Measured engine speed includes expected variations on a per-cycle basis.\",\n \"The expansion (combustion, power) cycle has a faster engine speed than the intake, compression, and exhaust cycles.\",\n \"The standard deviation accounts for the expected variations on a per-cycle basis so that only engine speed changes in excess of the standard deviation, or in excess of the standard deviation modified by an error factor (e.g., multiplied or added to the standard deviation), are used to trigger a change in throttle plate position by the engine governing system.\",\n \"Both load sensing systems make use of an appropriate controller to implement the control schemes discussed above and of an appropriate engine speed sensor to detect the engine speed for use as an input as discussed above.\",\n \"Possible engine speed sensors include a magnetic field sensor (e.g., a Hall Effect sensor or reed switch) in combination with a magnet on the flywheel.\",\n \"The magnet on the flywheel could be the same used to generate the spark for the ignition system, but could also be a separate second magnet.\",\n \"Both load sensing systems could also include an operating mode input to provide a verification that the detected change in load based on the engine speed calculations as an intended change in load based on the user's intended operating mode.\",\n \"For example, a tilt sensor could indicate when the front wheels of a walk behind lawn mower are lifted off the ground, thereby confirming a reduced load.\",\n \"A switch on the bail of walk behind lawn mower could indicate when the operator engages the drive system.\",\n \"A vacuum sensor could detect changes in engine vacuum as a redundant check on load changes.\",\n \"A user-actuated switch could also be used as a feedforward input to the load sensing system.\",\n \"For example, a switch actuated by a user operated lever (e.g., the bail of a walk-behind mower, the trigger of a pressure washer spray gun, a control lever of a snowthrower, a power takeoff engage switch on a riding tractor, etc.)\",\n \"would indicate an expected engine load to the load sensing system (e.g., operation of the tool driven by the engine, a load on the tool driven by the engine, engagement of a drive train, etc.).\",\n \"The load sensing system could use this feedforward input to override or supplement the load output provided by the load sensing system.\",\n \"The same controller or separate controllers can be used to implement the controls schemes used by the electronic governor system and by the load sensing system.\",\n \"For example, as shown in FIG.\",\n \"2, the controller 155 could be used to control both the electronic governor system 100 and a load sensing system as described above via a load sensing module 235 configured to implement a load sensing system as described herein.\",\n \"The engine speed sensor 160 could be used to provide the necessary

nervous system with the preservation of myenteric ganglia is required for intestinal motility and function.","Motor neurons of the myenteric ganglia predominantly express acetylcholine/tachykinins (excitatory) or nitric oxide/inhibitory peptides/purines (inhibitory) to mediate smooth muscle contraction and relaxation.","Partial, selective, or total loss of nerve function and/or loss of nerve cell populations within organs and other body structures are characteristic of numerous diseases and disorders.","For example, aganglionosis of various lengths of distal gut is the central pathology in Hirschsprung's disease.","Enteric neuropathy is also secondary to several other disorders (e.g., diabetes, Parkinson's disease, and inflammation) resulting in gastrointestinal dysfunction.","Gastrointestinal motor function is controlled by the intramural enteric nervous system.","It is a complex interplay between the smooth muscle of the muscularis externa and the two enteric neuronal plexi.","Neural stem cell therapy is an emerging therapy that aims to reinstate neuronal function and thus gastrointestinal motor function by repopulating the enteric plexi.","The research is driven by two significant findings: i) neural stem cells can be isolated from adult mammalian gut, including the ganglionated colon of Hirschsprung's patients; and ii) neural stem cells can be induced to differentiate into several neuronal subtypes and glia characteristic of the enteric nervous system (ENS) upon transplantation into explant cultures of aganglionic/aneural gut, or in vivo into distal colo-rectums in animal models.","While neural-crest derived enteric neural stem cells have been isolated from adult mammalian guts, including ganglionic bowel of patients with Hirschsprung's disease, there is little information or understanding of microenvironment-driven differentiation, and only limited studies describing subsequent functional behavior of these differentiated neurons in vitro.","Moreover, restoration of nerve functions by neural stem cell transplantations as a treatment for nerve-loss associated disorders has not yet been clinically demonstrated, and there exists a need for methods and materials to support neuroglial cells, and to ensure phenotypic stability and long term survival of transplanted or implanted neural stem cells."],[" SUMMARY It has been discovered that extracellular matrix (ECM) compositions can modulate neural stem cell fate and direct differentiation.","The term “extracellular matrix” or “ECM” is used herein to denote composition comprising one or more of the following: collagen I, collagen IV, laminin, heparan sulfate, or fragments of one or more of such proteins.","One aspect of the invention includes a method of biasing neural stem cell differentiation having the steps of obtaining a population of smooth muscle cells, culturing the smooth muscle cells to form a uniaxially-aligned smooth muscle sheet, obtaining a population of neural stem cells, culturing the neural stem cells in a hydrogel, wherein the hydrogel is applied to the uniaxially-aligned smooth muscle sheet, and exposing the neural stem cells to at least one extracellular matrix (ECM) component, wherein the ECM component biases differentiation of the neural stem cells into differentiated neural stem cells that are enriched for a neuronal subtype.","For example, the neuronal subtype are cholinergic neurons, where the hydrogel can include collagen I, or at least at least about 800 μg/ml collagen I, or between about 800 μg/ml and about 1600 μg/ml collagen I.","In another example, the neuronal subtype are nitrergic neurons, where the hydrogel can include collagen IV and be substantially free of laminin, or at least about 200 μg/ml collagen IV and be substantially free of laminin.","In another example, the neuronal subtype are peptidergic neurons, where the hydrogel can include collagen I, collagen IV, and laminin, or at least about 800 μg/ml collagen I, at least about 200 μg/ml collagen IV, and at least about 5 μg/ml laminin.","Another aspect of the invention can include isolating the differentiated neural stem cells and administering the differentiated neural stem cells to a patient.","For example, the administering can include injecting, into the patient, the differentiated stem cells in the hydrogel.","In another example, the differentiated neural stem cells innervate the uniaxially-aligned smooth muscle sheet to form an innervated smooth muscle sheet and can include the additional step of implanting the innervated smooth muscle sheet into a patient.","Another aspect of the invention includes a method of biasing neural stem cell differentiation having the steps of obtaining a population of neural stem cells, obtaining a population of smooth muscle cells, culturing the neural stem cells in the presence of the smooth muscle cells, wherein the neural stem cells adhere on a substrate with a substrate coating comprising at least one extracellular matrix (ECM) component, wherein the ECM component biases differentiation of the neural stem cells

comprises laminin, and at least one of collagen I and collagen IV, or the substrate coating comprises collagen I and collagen IV, and at least one of laminin and heparan sulfate.","Another aspect of

the number of neurons and the branching of neuronal processes and initiation of neuronal network formation.","Various neural ECM components were evaluated individually and in combination to study their effect of neuroglial differentiation of adult enteric neural progenitor cells.","In another aspect of the invention, tissue-engineered intestinal longitudinal smooth muscle sheets can be innervated using enteric neuronal progenitor cells embedded with hydrogels of varying ECM composition.","Differentiated neuronal composition (cholinergic, nitrergic, peptidergic), as well as functional neuronal physiology mediating smooth muscle contraction/relaxations, were evaluated.","Several functional differentiated neuronal subtypes were present in tissue-engineered intestinal

balanced between the two (composite collagen I and collagen IV, and laminin and/or heparan sulfate).","Additionally, an increase in peptidergic neurons was detected with laminin and heparan sulfate.","The feasibility of transplantation of various types of neuronal progenitor cells (CNS-derived, neural tube-derived, embryonic and adult ENS-derived) in explant cultures of aneural gut is well established.","However, conditions required for successful engraftment and long-term survival, focusing on a permissive environment heretofore have not been identified.","Studies related to in vitro differentiation of adult enteric neuronal progenitor cells with a focus on the role of the ECM can help optimize the survivability and maintenance of both neuronal and neuroglial

RO1DK042876.The U.S. government has certain rights in the invention.","TECHNICAL FIELD The field of this invention is tissue engineering and, in particular, re-innervation of organs and body tissue.","BACKGROUND An uninterrupted enteric nervous system with the preservation of myenteric ganglia is required for intestinal motility and function.","Motor neurons of the myenteric ganglia predominantly express acetylcholine/tachykinins (excitatory) or nitric oxide/inhibitory peptides/purines (inhibitory) to mediate smooth muscle contraction and relaxation.","Partial, selective, or total loss of nerve function and/or loss of nerve cell populations within organs and other body structures are characteristic of numerous diseases and disorders.","For example, aganglionosis of various lengths of distal gut is the central pathology in Hirschsprung's disease.","Enteric neuropathy is also secondary to several other disorders (e.g., diabetes, Parkinson's disease, and inflammation) resulting in gastrointestinal dysfunction.","Gastrointestinal motor function is controlled by the intramural enteric nervous system.","It is a complex interplay between the smooth muscle of the muscularis externa and the two enteric neuronal plexi.","Neural stem cell therapy is an emerging therapy that aims to reinstate neuronal function and thus gastrointestinal motor function by repopulating the enteric plexi.","The research is driven by two significant findings: i) neural stem cells can be isolated from adult mammalian gut, including the ganglionated colon of Hirschsprung's patients; and ii) neural stem cells can be induced to differentiate into several neuronal subtypes and glia characteristic of the enteric nervous system (ENS) upon transplantation into explant cultures of aganglionic/aneural gut, or in vivo into distal colo-rectums in animal models.","While neural-crest derived enteric neural stem cells have been isolated from adult mammalian guts, including ganglionic bowel of patients with Hirschsprung's disease, there is little information or understanding of microenvironment-driven differentiation, and only limited studies describing subsequent functional behavior of these differentiated neurons in vitro.","Moreover, restoration of nerve functions by neural stem cell transplantations as a treatment for nerve-loss associated disorders has not yet been clinically demonstrated, and there exists a need for methods and materials to support neuroglial cells, and to ensure phenotypic stability and long term survival of transplanted or implanted neural stem cells.","SUMMARY It has been discovered that extracellular matrix (ECM) compositions can modulate neural stem cell fate and direct differentiation.","The term “extracellular matrix” or “ECM” is used herein to denote composition comprising one or more of the following: collagen I, collagen IV, laminin, heparan sulfate, or fragments of one or more of such proteins.","One aspect of the invention includes a method of biasing neural stem cell differentiation having the steps of obtaining a population of smooth muscle cells, culturing the smooth muscle cells to form a uniaxially-aligned smooth muscle sheet, obtaining a population of neural stem cells, culturing the neural stem cells in a hydrogel, wherein the hydrogel is applied to the uniaxially-aligned smooth muscle sheet, and exposing the neural stem cells to at least one extracellular matrix (ECM) component, wherein the ECM component biases differentiation of the neural stem cells into differentiated neural stem cells that are enriched for a neuronal subtype.","For example, the neuronal subtype are cholinergic neurons, where the hydrogel can include collagen I, or at least at least about 800 μg/ml collagen I, or between about 800 μg/ml and about 1600 μg/ml collagen I.","In another example, the neuronal subtype are nitrergic neurons, where the hydrogel can include collagen IV and be substantially free of laminin, or at least about 200 μg/ml collagen IV and be substantially free of laminin.","In another example, the neuronal subtype are peptidergic neurons, where the hydrogel can include collagen I, collagen IV, and laminin, or at least about 800 μg/ml collagen I, at least about 200 μg/ml collagen IV, and at least about 5 μg/ml laminin.","Another aspect of the invention can include isolating the differentiated neural stem cells and administering the differentiated neural stem cells to a patient.","For example, the administering can include injecting, into the patient, the differentiated stem cells in the hydrogel.","In another example, the differentiated neural stem cells innervate the uniaxially-aligned smooth muscle sheet to form an innervated smooth muscle sheet and can include the additional step of implanting the innervated smooth muscle sheet into a patient.","Another aspect of the invention includes a method of biasing neural stem cell differentiation having the steps of obtaining a population of neural stem cells, obtaining a population of smooth muscle cells, culturing the neural stem cells in the presence of the smooth muscle cells, wherein the neural stem cells adhere on a substrate with a substrate coating comprising at least one extracellular matrix (ECM) component, wherein the ECM component biases differentiation of the neural stem cells into differentiated neural stem cells that are enriched for neurons.","For example, the substrate coating comprises at least one of laminin, collagen I, and collagen IV, or the substrate coating comprises laminin, and at least one of collagen I and collagen IV, or the substrate coating comprises collagen I and collagen IV, and at least one of laminin and heparan sulfate.","Another aspect of the invention can also include isolating the differentiated neural stem cells and administering the differentiated neural stem cells to a patient.","For example, the administering can include injecting the differentiated neural stem cells into the patient.","Another aspect of the invention includes a method of biasing neural stem cell differentiation by obtaining a population of neural stem cells, obtaining a population of smooth muscle cells, culturing the neural stem cells in the presence of the smooth muscle cells, wherein the neural stem cells adhere on a substrate with a substrate coating comprising at least one extracellular matrix (ECM) component, wherein the ECM component biases differentiation of the neural stem cells into differentiated neural stem cells that are enriched for glial cells.","For example, the substrate coating can include at least collagen I and collagen IV, and be substantially free of at least one of laminin and heparan sulfate, or the substrate coating can comprises at least 5 μg/cm2 collagen I and at least 5 μg/cm2 collagen IV, and be substantially free of at least one of laminin and heparan sulfate.","Another aspect further includes the step of isolating the differentiated neural stem cells and administering the differentiated neural stem cells to a patient.","For example, the administering comprises injecting the differentiated neural stem cells into the patient.","In one aspect of the invention, adult mammalian enteric neural progenitor cells can be induced to differentiate on various substrates derived from components or combinations of ECM compositions.","Neuronal and glial differentiation was studied as a function of ECM composition.","Collagen I and collagen IV substrates supported neuronal differentiation and extensive glial differentiation individually and in combination.","The addition of laminin or heparan sulfate to collagen substrates improved neuronal differentiation, increasing the number of neurons and the branching of neuronal processes and initiation of neuronal network formation.","Various neural ECM components were evaluated individually and in combination to study their effect of neuroglial differentiation of adult enteric neural progenitor cells.","In another aspect of the invention, tissue-engineered intestinal longitudinal smooth muscle sheets can be innervated using enteric neuronal progenitor cells embedded with hydrogels of varying ECM composition.","Differentiated neuronal composition (cholinergic, nitrergic, peptidergic), as well as functional neuronal physiology mediating smooth muscle contraction/relaxations, were evaluated.","Several functional differentiated neuronal subtypes were present in tissue-engineered intestinal sheets, capable of mediating smooth muscle contraction/relaxation.","Neuronal populations varied from being highly cholinergic (collagen I), highly nitrergic (composite collagen I and collagen IV), or balanced between the two (composite collagen I and collagen IV, and laminin and/or heparan sulfate).","Additionally, an increase in peptidergic neurons was detected with laminin and heparan sulfate.","The feasibility of transplantation of various types of neuronal progenitor cells (CNS-derived, neural tube-derived, embryonic and adult ENS-derived) in explant cultures of aneural gut is well established.","However, conditions required for successful engraftment and long-term survival, focusing on a permissive environment heretofore have not been identified.","Studies related to in vitro differentiation of adult enteric neuronal progenitor cells with a focus on the role of the ECM can help optimize the survivability and maintenance of both neuronal and neuroglial phenotypes.","Moreover, our studies indicate that neuronal differentiation can be modulated by varying the composition of ECM microenvironments.","Enriched populations of differentiated neuronal subtypes can be derived within transplantable tissue engineered sheets, using ECM microenvironments.","ECM microenvironments may also facilitate adequate trophic support and phenotype maintenance of differentiated neurons.","In certain embodiments, neural differentiation is induced by administering an effective amount of laminin or a composition comprising laminin, including fragments, derivatives, or analogs thereof.","In a specific example, the laminin can be a complete laminin protein.","In further examples, the laminin is selected from laminin-1, laminin-2, laminin-4, and fragments or combinations thereof.","In further examples, the laminin or laminin composition includes a substance at least substantially homologous to laminin-1, laminin-2, or laminin-4.In yet further implementations, the laminin or laminin composition comprises a polypeptide at least substantially homologous to the laminin al chain, e.g., having at least 80%, or 85%, or 90%, or 95% sequence identical to at least a fragment of the laminin α1 chain that retains the capacity to induce neuroglial differentiation.","Amounts effective for various therapeutic treatments of the present disclosure may, of course, depend on the severity of the disease and the weight and general state of the subject, as well as the absorption, inactivation, and excretion rates of the therapeutically-active compound or component, the dosage schedule, and amount administered, as well as other factors known to those of ordinary skill in the art.","It also should be apparent to one of ordinary skill in the art that the exact dosage and frequency of administration will depend on the particular laminin, laminin composition, or other therapeutic substance being administered, the particular condition being treated, the severity of the condition being treated, the age, weight, general physical condition of the particular subject, and other medication the subject may be taking.","Typically, dosages used in vitro may provide useful guidance in the amounts useful for in vivo administration of the pharmaceutical composition, and animal models may be used to determine effective dosages for treatment of particular disorders.","For example, animal models of neural disorders may be used to determine effective dosages that can then be translated to dosage amount for other subjects, such as humans, as known in the art.","Various considerations in dosage determination are described, e.g., in Gilman et al., eds., Goodman And Gilman's: The Pharmacological Bases of Therapeutics, 8th ed., Pergamon Press (1990); and Remington's Pharmaceutical Sciences, 17th ed., Mack Publishing Co., Easton, Pa. (1990), which is herein incorporated by reference.","In another example, the laminin or laminin composition can be introduced into an in vitro culture of neural stem cells (or co-administered with neural stem cells to a subject) in an amount sufficient to provide a dose of laminin of between about 10 fmol/g and about 500 nmol/g, such as between about 2 nmol/g and about 20 nmol/g or between about 2 nmol/g and about 10 nmol/g.","In additional examples, the laminin or laminin composition can be provided in vitro or administered to a subject in an amount sufficient to provide a dose of laminin of between about 0.01 μg/kg and about 1000 mg/kg or between about 0.1 mg/kg and about 1000 mg/kg, in particular examples this amount is provided per day or per week.","In another example, the laminin or laminin composition is administered to a subject in an amount sufficient to provide a dose of laminin of between about 0.2 mg/kg and about 2 mg/kg.","In further examples, the laminin or laminin composition is administered to a subject in an amount sufficient to provide a concentration of laminin in the administrated material of between about 5 nM and about 500 nM, such as between about 50 nM and about 200 nm, or about 100 nM.","Addition of heparan sulfate to composite collagen mixtures can improve neuronal differentiation as well.","Neuronal networking and neuronal clustering was visible at the later time point.","Heparan sulfate and its interaction with glial cell-derived neurotrophic factor (GDNF) and other neurotrophic factors stabilizes and makes these factors locally available, possibly modulating neurite outgrowth and neuronal differentiation.","Heparan sulfate interacts with both collagen IV and with laminin, to positive modulate neuronal differentiation, evidenced by the enhanced neurite outgrowth, axonal lengths and initiation of neuronal networking (FIG.","4 A-H).","Composite collagen substrates with laminin and/or heparan sulfate all maintained a low level of glial fibrillary acidic protein (GFAP) positive glial cells, with initiation of astrocytic networking becoming more obvious at the later time point.","In general, substrates that supported neuronal differentiation demonstrated a bare minimum of glial cells required to possibly support neuronal cell phenotype or survival.","Taken together, these results help identify optimal 3D matrix compositions to encapsulate neuronal progenitor cells.","In certain embodiments, three dimensional hydrogel environments can also provide the mechanical cues for neural differentiation.","For

context clearly dictates otherwise.","Thus, for example, references to “the method” includes one or more methods, and/or steps of the type described herein which will become apparent to those persons skilled in the art upon reading this disclosure and so forth.","The steps of any method can be practice in feasible order and are restricted to a sequential order merely because they are so recited in a claim.","Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.","Although any methods and materials similar or equivalent to those described herein can be used in the practice or testing of the invention, the preferred methods and materials are now described.","“Differentiation” refers to a change that occurs in cells to cause those cells to assume certain specialized functions and to lose the ability to change into certain other specialized functional units.","Cells capable of differentiation may be any of totipotent, pluripotent or multipotent cells.","Differentiation may be partial or complete with respect to mature adult cells.","Stem cells are undifferentiated cells defined by the ability of a single cell both to self-renew, and to differentiate to produce progeny cells, including self-renewing progenitors, non-renewing progenitors, and terminally differentiated cells.","Stem cells are also characterized by their ability to differentiate in vitro into functional cells of various cell lineages from multiple germ layers (endoderm, mesoderm and ectoderm), as well as to give rise to tissues of multiple germ layers following transplantation, and to contribute substantially to most, if not all, tissues following injection into blastocysts.","Neural stem cells can be isolated from embryonic and adult central nervous system (CNS) tissue, neural tube tissue or enteric nervous system (ENS) tissue.","Stem cells can be further classified according to their developmental potential as: (1) totipotent; (2) pluripotent; (3) multipotent; (4) oligopotent; and (5) unipotent.","Totipotent cells are able to give rise to all embryonic and extra-embryonic cell types.","Pluripotent cells are able to give rise to all embryonic cell types.","Multipotent cells include those able to give rise to a subset of cell lineages, but all within a particular tissue, organ, or physiological system (for example, hematopoietic stem cells (HSC) can produce progeny that include HSC (self-renewal), blood cell-restricted oligopotent progenitors, and all cell types and elements (e.g., platelets) that are normal components of the blood).","Cells that are oligopotent can give rise to a more restricted subset of cell lineages than multipotent stem cells; and cells that are unipotent typically are only able to give rise to a single cell lineage.","In a broader sense, a progenitor cell is a cell that has the capacity to create progeny that are more differentiated than itself, and yet retains the capacity to replenish the pool of progenitors.","By that definition, stem cells themselves are also progenitor cells, as are the more immediate precursors to terminally differentiated cells.","When referring to the cells of the present invention, as described in greater detail below, this broad definition of progenitor cell may be used.","In a narrower sense, a progenitor cell is often defined as a cell that is intermediate in the differentiation pathway, i.e., it arises from a stem cell and is intermediate in the production of a mature cell type or subset of cell types.","This type of progenitor cell is generally not able to self-renew.","Accordingly, if this type of cell is referred to herein, it will be referred to as a non-renewing progenitor cell or as an intermediate progenitor or precursor cell.","As used herein, the phrase “differentiates into a neural lineage or phenotype” refers to a cell that becomes partially or fully committed to a specific neural phenotype of the CNS or PNS, i.e., a neuron or a glial cell, the latter category including without limitation astrocytes, oligodendrocytes, Schwann cells and microglia.","The term “neural” as used herein is intended to encompass all electrical active cells, e.g., cells that can process or transmit information through electrical or chemical signals, including the aforementioned neurons, glial cells, astrocytes, oligodendrocytes, Schwann cells and microglia.","For the purposes of this disclosure, the terms “neural progenitor cell” or “neural precursor cell” mean a cell that can generate progeny that are either neuronal cells (such as neuronal precursors or mature neurons) or glial cells (such as glial precursors, mature astrocytes, or mature oligodendrocytes).","Typically, the cells express some of the phenotypic markers that are characteristic of the neural lineage.","Typically, they do not produce progeny of other embryonic germ layers when cultured by themselves in vitro, unless dedifferentiated or reprogrammed in some fashion.","A “neuronal progenitor cell” or “neuronal precursor cell” is a cell that can generate progeny that are mature neurons.","These cells may or may not also have the capability to generate glial cells.","A “glial progenitor cell” or “glial precursor cell” is a cell that can generate progeny that are mature astrocytes or mature oligodendrocytes.","These cells may or may not also have the capability to generate neuronal cells.","The phrase “biocompatible substance” and the terms “biomaterial” and “substrate” are used interchangeably and refer to a material that is suitable for implantation or injection into a subject.","A biocompatible substance does not cause toxic or injurious effects once implanted in the subject.","In one embodiment, the biocompatible substrate includes at least one component of extracellular matrix.","In other embodiments, the substrate can also include a polymer with a surface that can be shaped into the desired structure that requires repairing or replacing.","The polymer can also be shaped into a part of a body structure that requires repairing or replacing.","In another embodiment, the biocompatible substrate can be injected into a subject at a target site.","In one embodiment, the substrate is an injectable or implantable biomaterial that can be composed of crosslinked polymer networks which are typically insoluble or poorly soluble in water, but can swell to an equilibrium size in the presence of excess water.","For example, a hydrogel can be injected into desired locations within the organ.","In one embodiment, the collagen can be injected alone.","In another embodiment, the collagen can be injected with other hydrogels.","The hydrogel compositions can include, without limitation, for example, poly(esters), poly(hydroxy acids), poly(lactones), poly(amides), poly(ester-amides), poly(amino acids), poly(anhydrides), poly(ortho-esters), poly(carbonates), poly(phosphazines), poly(thioesters), polysaccharides and mixtures thereof.","Furthermore, the compositions can also include, for example, a poly(hydroxy) acid including poly(alpha-hydroxy) acids and poly(beta-hydroxy) acids.","Such poly(hydroxy) acids include, for example, polylactic acid, polyglycolic acid, polycaproic acid, polybutyric acid, polyvaleric acid, and copolymers and mixtures thereof.","Hydrogels with effective pore sizes in the 10-100 nm range and in the 100 nm-10 micrometer range are termed “microporous” and “macroporous” hydrogels, respectively.","Microporous and macroporous hydrogels are often called polymer “sponges.” When a monomer, e.g., hydroxyethyl methacrylate (HEMA), is polymerized at an initial monomer concentration of 45 (w/w) % or higher in water, a hydrogel is produced with a porosity higher than the homogeneous hydrogels.","Hydrogels can also expand in the presence of diluent (usually water).","The matrix materials of present invention encompass both conventional foam or sponge materials and the so-called “hydrogel sponges.” For a further description of hydrogels, see U.S. Pat.","No.","5,451,613 (issued to Smith et al.)","herein incorporated by reference.","The term “extracellular matrix” or “ECM” is used herein to denote compositions comprising one or more of the following: collagen I, collagen IV, laminin, heparan sulfate, or fragments of one or more of such proteins.","“Collagen I” refers to collagen I or collagen I compositions derived from cell culture, animal tissue, or recombinant means, and may be derived from human, murine, porcine, or bovine sources.","“Collagen I” also refers to substances or polypeptide(s) at least substantially homologous to collagen I or collagen I compositions.","Additionally, “collagen I” refers to collagen I or collagen I compositions that do not include a collagen I fragment, e.g., including essentially only a complete collagen I protein.","“Collagen IV” refers to collagen IV or collagen IV compositions derived from cell culture, animal tissue, or recombinant means, and may be derived from human, murine, porcine, or bovine sources.","“Collagen IV” also refers to substances or polypeptide(s) at least substantially homologous to collagen IV or collagen IV compositions.","Additionally, “collagen IV” refers to collagen IV or collagen IV compositions that do not include a collagen IV fragment, e.g., including essentially only a complete collagen I protein.","“Laminin” refers to laminin, laminin fragments, laminin derivatives, laminin analogs, or laminin compositions derived from cell culture, recombinant means, or animal tissue.","“Laminin” can be derived from human, murine, porcine, or bovine sources.","“Laminin” refers to laminin or laminin compositions comprising laminin-1, laminin-2, laminin-4, or combinations thereof.","“Laminin” also refers to substances or polypeptide(s) at least substantially homologous to laminin-1, laminin-2, or laminin-4.Additionally, “laminin” refers to laminin or laminin compositions that do not include a laminin fragment, e.g., including essentially only a complete laminin protein.","The term “substantially free of laminin” and “free of laminin” are used interchangeably herein to denote compositions in which laminin is absent or present in such low concentrations that it does not play any significant role in neural stem cell differentiation, e.g., where laminin is only present in concentrations less than 5 μg/ml in hydrogels or 5 μg/cm on substrate coatings, or more preferably less than 2 μg/ml in hydrogels or 2 μg/cm2 on substrate coatings, or less than 1 μg/ml in hydrogels or 1 μg/cm on substrate coatings, and in some instances less than 0.1 μm/ml in hydrogels or 0.1 μm/cm2 on substrate coatings.","The term “substantially free of heparan sulfate” and “free of heparan sulfate” are

humans; as well as non-human primates, domestic animals, livestock, and other non-human mammals.","Neural Glial Differentiation Enteric neuronal progenitor cells have been identified in the adult mammalian gut, and have been isolated from humans up to and over 80 years of age.","Previously, several groups have shown that a self-renewing population of Sox 2, Sox10, Nestin and p75 positive neural-crest derived progenitor cells can be isolated either from full-thickness, muscularis or mucosal biopsies of the adult mammalian gut.","These cells have been demonstrated to have the potential to differentiate into several neuronal subtypes including inhibitory and excitatory motor neurons and glia.","Various types of neuronal progenitor cells (CNS-derived, neural tube-derived, embryonic and adult ENS-derived) from explant cultures of aneural gut can also be transplanted.","Alterations in the extracellular matrix of the gut mesenchyme has been documented in aganglionic regions of rodent gut, suggesting the importance of a permissive extracellular environment to promote effective in utero colonization and differentiation of neural crest cells in the developing gut.","Since transplantation and subsequent functional neo-innervation is one clinical goal of neural stem cell transplantation, in vitro studies should mimic developmental conditions in vivo, in terms of providing a permissive and favorable ECM (such as a three-dimensional environment).","Understanding the role of the ECM in affecting neuroglial differentiation of adult enteric neuronal progenitor cells can enhance the survivability and maintenance of a stable phenotype upon transplantation.","Mammalian myenteric ganglia in vivo are surrounded by a matrix comprised predominantly of type IV collagen, laminin, heparan sulphate proteoglycan, and entactin.","The enteric plexus lacks large connective tissue spaces for blood vessels like the peripheral nervous system.","The two-dimensional culture substratum may modulate neuronal and glial differentiation based on ECM composition.","Different ECM components may influence enteric glia and neurons come in to contact with in vivo in the adult myenteric plexus, such as collagen IV, laminin and heparan sulfate.","Addition of laminin to collagen substrates unexpectedly improved neurite outgrowth with longer neurite lengths (compare 156.1±7.2 μm to 215.1±7.6 μm).","while there was an overall enhancement in neuronal differentiation as well as neurite outgrowth, there was no significant difference between the additions of 5 or 10 μg/cm2 of laminin.","This empirical determination was important in determining a minimal amount of laminin that can influence neuroglial differentiation without affecting neurite outgrowth adversely in a situation that requires neo-innervation of denervated tissues.","Addition of heparan sulfate to composite collagen mixtures improved neuronal differentiation as well.","Neuronal networking and neuronal clustering was visible at the later time point.","Heparan sulfate may interact with GDNF and other neurotrophic factors to stabilize and make the factors locally available.","Heparan sulfate interacts with both collagen IV and with laminin, to positively modulate neuronal differentiation.","In one embodiment, heparan sulfate is added to the collagen mixture.","Composite collagen substrates with laminin and/or heparan sulfate all maintained a low level of GFAP positive glial cells, with initiation of astrocytic networking becoming more obvious at the later time point.","In general, substrates that supported neuronal differentiation demonstrated a bare minimum of glial cells required to possibly support neuronal cell phenotype or survival.","Substrates that supported neuronal differentiation may result in enriched populations of neuronal cells comprising greater than 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 100%, or any intermediate percentage.","Enteric neurospheres demonstrated a tendency to differentiate into glia on PLL coated substrates as well as on composite collagen substrates in the absence of laminin and heparan sulfate.","In contract, culture substrates with laminin and heparan sulfate promoted extensive neuronal differentiation while simultaneously supporting only a minimal glial cell population.","Laminin and collagen IV coated coverslips positively modulated neuronal differentiation by increased number of neurites per neuron and longer neurite lengths compared to fibrillar collagen I (FIG.","2B-D, F-H).","Taken together, these results identify suitable 3D matrix compositions to deliver neuronal progenitor cells.","Three dimensional hydrogel environments also provide the mechanical cues for neural differentiation, more readily translatable to in vivo conditions than infinitely stiff glass substrates.","The extracellular matrix (ECM) plays an enormous role in dictating stem cell fate.","The ECM composition, structure and mechanical properties can all modulate progenitor cell differentiation.","The adult mammalian myenteric ganglia are surrounded by an extracellular matrix primarily composed of collagen IV, laminin and a heparan sulfate proteoglycan, with enteric glia always in direct contact with the ECM.","Enteric neurons also come in direct contact with this ECM, though much less frequently than glia.","Laminin, fibronectin and proteoglycans are expressed within the embyonic gut to aid its colonization by vagal neural crest cells.","Collagen IV is distributed in the developing nervous system along the neural crest.","Additionally, laminin promotes neural cell adhesion and axonal outgrowth.","Heparan sulfate is important for GDNF signaling in the gut, and stabilizes and influences neuronal differentiation in vitro.","It has been discovered that components of neural ECM can affect the differentiation of gut-derived neuronal progenitor cells of neural-crest lineage.","Two timepoints were defined to identify early and late differentiation events—day 5 (early) and day 15 (late) based on previous experiments.","Immunohistochemistry for βIII tubulin (neuron specific microtubule) and GFAP (Glial fibrillary acidic protein) was used to identify differentiated neurons and glia on coated culture substrata.","Substrates that supported glial differentiation may result in enriched populations of glial cells comprising greater than 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 100%, or any intermediate percentage.","Neuronal Subtype Differentiation Neural stem cell transplantation is a promising therapeutic approach to repopulate neurons within enteric ganglia.","A complete loss of neurons is reported in HSCR, and a partial loss of selective neuronal subtypes is documented in achalasia and stenosis.","Several groups have injected enteric neuronal progenitor cells into experimental models of aganglionosis, demonstrating the feasibility of transplantation.","However, there is inadequate focus on differentiation of progenitor cells into mature neuronal subtypes, and subsequent assessment of functionality.","Here, we describe one embodiment of the invention, whereby we describe a novel method to bias differentiation of enteric neuronal progenitor cells in vitro, prior to transplantation.","The ECM microenvironment, consisting of collagens, laminin and proteoglycans, not only acts as a structural framework for cells, but also plays an active role in aiding neurotrophic signaling.","In an embodiment of this invention, four ECM components (collagen I, collagen IV, laminin and heparan sulfate) were evaluated, three of which are known to be present in adult myenteric ganglia.","Collagen IV has been documented to be favorable for neurite outgrowth and neuronal differentiation.","Laminin has long been known for its neurite promoting activity, in central, peripheral, and enteric neurons.","The role of the heparan sulfate proteoglycan in neuronal differentiation is also well documented, both developmentally and in regenerative medicine applications.","Fibrillar Collagen I was used additionally in these studies for ease of gelation and incorporation of other ECM components within a 3D hydrogel.","Apart from composition, substrate elasticity has been demonstrated to affect the differentiation of adult neural stem cells, with neuronal differentiation reported between 100-500 Pa. ECM hydrogel compositions were adjusted in order to maintain their viscoelastic modulus within the range suitable for neuronal differentiation (FIG.","10, table).","Structural architecture was verified using scanning electron microscopy, wherein the addition of collagen IV demonstrated the presence of network structures, similar to self-assembled collagen IV in the mammalian basement membrane.","The addition of laminin did not alter the ultrastructure, because it was expected to coat collagen fibers evenly.","Additionally, laminin was also not expected to alter the stiffness/viscoelasticity of the gels, given the manner of its interaction with the collagen.","The glycosaminoglycan chains of heparan sulfate are documented to cross link between laminin and collagen IV, thereby pulling fibers into a more compact structure, and slightly increasing the viscoelasticity of ECM gels.","Smooth muscle cells within tissue engineered sheets drive the differentiation of enteric neuronal progenitor cells.","Tissue engineered sheets provided a good modality to assess variability of differentiated neurons due to ECM composition as well as the functionality of differentiated neurons.","The proximity to smooth muscle promoted the differentiation of enteric neuronal progenitor cells extensively.","In vitro differentiation of neural stem cells in the presence of gut-derived factors has been demonstrated previously by us and others.","Neurotrophic factors (NT-3, Neurturin, GDNF) and morphogens (BMP-2/4) capable of driving enteric neuronal progenitor cell proliferation and differentiation have been demonstrated to arise from the smooth muscle and mesenchyme of the developing and adult gut.","Recently, the postnatal bowel was demonstrated to support the differentiation of enteric neuronal progenitor cells, strengthening the fact that cues for differentiation can be derived from the postnatal gut.","Hence, it was expected that smooth muscle cells within the tissue engineered sheets would drive the differentiation of enteric neuronal progenitor cells.","We evaluated all tissue engineered sheets to ensure that the constituent smooth muscle cells demonstrated a contractile phenotype expressing Smoothelin (FIG.","14B).","Smoothelin expression has been previously demonstrated to be essential for contractility of smooth muscle.","In line with the equivalent expression of smoothelin, myogenic electromechanical coupling integrity was also equivalent in the tissue engineered sheets (FIG.","14A-D) Similar patterns of contractions were observed in tissue engineered sheets in response to KCl, regardless of ECM composition.","The ECM modulates differential neuronal subtypes while supporting overall smooth muscle-driven neuronal differentiation.","In the presence of the smooth muscle, enteric neuronal progenitor cells differentiated, and expressed similar amounts of pan-neuronal marker βIII Tubulin (FIG.","14A), suggesting that smooth muscle derived factors and substrate viscoelasticity were suitable for overall neuronal differentiation.","However, on closer examination of neural subtypes, there was a differential expression of excitatory and inhibitory markers within tissue engineered sheets with varying ECM compositions (FIG.","14).","Sheets containing laminin had a balanced expression of both ChAT and nNOS.","Kinetics of Ach-induced contraction in laminin sheets was most similar to native tissue, indicating the presence of an increased viable cholinergic neuronal component in composite collagen/laminin sheets.","Furthermore, attenuation of EFS-induced relaxation by L-NAME (˜62%) was also kinetically similar to native tissue (˜78%), indicating the presence of a nitrergic neuronal component.","Collagen I, in the absence of any other matrix components, was the ECM of choice when an enriched cholinergic neuronal population was required, with a significantly diminished nitrergic neuronal population (FIG.","14C-D).","While these sheets demonstrated a robust TTX-sensitive Ach-induced contraction commensurate with the heightened ChAT protein expression, relaxation in response to an electrical field was diminished.","Furthermore, there was minimal attenuation of relaxation upon the inhibition of nNOS, correlating with the low nNOS expression.","Substrates that supported cholinergic neuron differentiation may result in enriched populations of cholinergic neurons comprising greater than 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 100%, or any intermediate percentage.","Composite Collagen I/IV sheets had an enhanced nNOS protein expression, with an associated increase in EFS induced relaxation (FIG.","18B).","AUC of relaxation in composite Collagen I/IV sheets was comparable to native intestinal tissue.","However, both ChAT expression and contraction was lower in composite collagen sheets.","Substrates that supported nitrergic neuron differentiation may result in enriched populations of nitrergic neurons comprising greater than 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 100%, or any intermediate percentage.","The ECM is a framework upon which smooth muscle derived factors regulate differentiation of neural subtypes.","We demonstrate a critical role of collagen I and collagen IV containing ECM environments in promoting excitatory and inhibitory motor neurons, respectively.","The ECM microenvironment plays a role in modulating neurotrophic as well as morphogenetic signaling.","Morphogenetic signaling via the BMP family expressed in fetal gut is important for the phenotypic diversity of enteric ganglia, including nitrergic and VIP-ergic neuron differentiation.","Collagen IV is documented to modulate BMP signaling, and heparan sulfate modulates GDNF signaling in the gut.","Immunoreactivity of neurotrophic factor, NT-3, has been observed in ganglia and in the ECM molecules surrounding them, suggesting a role for a Collagen IV-based ECM to modulate NT-3 signaling.","The constituent smooth muscle phenotype in tissue engineered sheets was contractile, expressing smoothelin, and generating contractions and relaxations approaching ˜60% of those generated by native intestinal tissue.","Differentiation cues arising from the constituent smooth muscle cells drove enteric neuronal differentiation.","Furthermore, it is likely that the ECM could act as a framework for smooth muscle-derived factors, enhancing or inhibiting their effects, resulting in the generation of differential neuronal phenotypes.","EXAMPLES Reagents All tissue culture reagents were purchased from Invitrogen (Carlsbad, Calif.) unless specified otherwise.","Primary

(FIG.","13A-D).","Substrates that supported peptidergic neuron differentiation may result in enriched populations of peptidergic neurons comprising greater than 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%,

Electromechanical coupling integrity of constituent smooth muscle cells was first evaluated using potassium chloride (KCl).","KCl treatment elicited rapid contractions that were sustained for ˜5 minutes (FIG.","14).","Peak maximal contraction in response to KCl was similar between the different tissue engineered sheets (FIG.","14A-D), ranging from 279.5±4.79 μN to 296.5±6.26 μN.","This correlated with the equivalent expression of contractile smooth muscle marker, Smoothelin, indicating that the constituent smooth muscle cells within the tissue engineered sheets maintained a contractile phenotype regardless of ECM composition.","Furthermore, KCl-induced contractions in tissue engineered sheets were similar to native rabbit intestinal tissues (FIG.","14E) in time course, but slightly reduced in magnitude.","Peak KCl-induced contractions in native tissue averaged 373.5±10.63 μN.","KCl-induced contraction was unaffected by pre-treatment with neuronal blocker TTX (grey

was significantly higher in native rabbit intestinal tissues.","Although reduced in magnitude compared to native tissue, KCl-induced contractions were similar among the different tissue engineered sheets, indicating a robust contractile smooth muscle phenotype unaffected by the ECM composition.","Acetylcholine-Induced Contraction: Exogenous addition of 1 μM Acetylcholine (Ach) was used to simulate agonist-induced contraction.","All tissue engineered sheets contracted in response to Ach, and sustained contractions up to ˜5 minutes post stimulation with Ach (FIG.","15A-D).","Tissue engineered sheets with composite collagen I/IV with laminin had a significantly elevated peak maximal Ach-induced contraction (FIG.","15C; 232.9±8.167 μN), as well as an elevated area under the curve of contraction (47606±2054 AU).","Magnitude of Ach-induced contraction was still significantly lower compared to contraction in native tissue (342.6±3.15 μN; 70448±5876 AU).","However, the time course of contraction was very similar to native tissue in tissue engineered sheets containing laminin, reaching maximal contraction within a minute of agonist stimulation.","Collagen I sheets also had an elevated Ach-induced contraction (FIG.","15A; 238.9±13.72 μN; 42668±2172 AU) corresponding to the elevated ChAT protein expression.","However, the kinetics of contraction did not match native tissue.","In order to estimate the smooth muscle (myogenic) component of Ach-induced contraction, neurotoxin TTX was used as a pretreatment (grey traces, FIG.","15).","Area under the curves of contraction was compared with and without TTX pre-treatment in order to estimate % inhibition (FIG.","15F).","Percent inhibition of Ach-induced contraction in the presence of TTX was highest in two ECM conditions: i) collagen I sheets (72.77±2.45%); and ii) collagen I/IV/laminin sheets (60.58±1.66%).","These values of % inhibition were similar to that observed in native tissue (72.73±3.66%) upon TTX-pretreatment.","This increased neuronal contribution to Ach-induced contraction also correlated with the elevated protein expression of ChAT in collagen I and composite collagen I/IV/laminin

stimulate neurons within the tissue engineered sheets to produce relaxation of smooth muscle (FIG.","16).","The extent of relaxation was quantified as area under the curve of relaxation.","Extent of relaxation significantly varied amongst the tissue engineered sheets with varying ECM compositions.","Sheets bioengineered with collagen IV, which displayed elevated nNOS expression, had higher relaxation compared to sheets bioengineered with collagen I only (compare 109693±8465 AU in collagen I/IV sheets to 23142±4921 in collagen I sheets).","Sheets containing laminin and/or heparan sulfate also had significantly elevated relaxation compared to collagen I sheets (68395-69025 AU).","In response to EFS, native tissues relaxed generating 101550±11279 AU.","Tissue engineered sheets with collagen IV and/or laminin and/or heparan sulfate additionally had a time course of relaxation most similar to native tissue.","Maximal relaxation was achieved within 2 minutes of EFS, and a subsequent recovery of basal force was complete within 10 minutes.","Upon pre-treatment with TTX, EFS-induced relaxation was inhibited entirely (grey traces, FIG.","16).","Inhibition of Nitric Oxide Synthase: In order to identify the presence and functionality of nitrergic neurons, an inhibitor of nitric oxide synthase (L-NAME) was used (grey traces, FIG.","17).","Percent inhibition was determined by comparing areas under the curves of maximal relaxation with and without the L-NAME pre-treatment.","Percent inhibition with L-NAME treatment was the lowest in collagen I sheets (33.37±8.37%; grey trace, FIG.","17A).","This corresponded to the low protein expression of nNOS in collagen I sheets compared to sheets containing collagen IV (FIG.","12D).","In contrast, the

VIP-ergic neurons was assessed using a VIP receptor antagonist (VIP-Ra).","Pre-treatment with VIP-Ra inhibited maximal relaxation in all tissue engineered sheets to varying extents ranging from 55.55±3.92%-65.92±5.38% (grey traces, FIG.","18).","Inhibition of EFS-induced relaxation indicated the presence of differentiated VIP-ergic neurons in tissue engineered sheets.","The section headings

be transplanted.\",\n \"Alterations in the extracellular matrix of the gut mesenchyme has been documented in aganglionic regions of rodent gut, suggesting the importance of a permissive extracellular environment to promote effective in utero colonization and differentiation of neural crest cells in the developing gut.\",\n \"Since transplantation and subsequent functional neo-innervation is one clinical goal of neural stem cell transplantation, in vitro studies should mimic developmental conditions in vivo, in terms of providing a permissive and favorable ECM (such as a three-dimensional environment).\",\n \"Understanding the role of the ECM in affecting neuroglial differentiation of adult enteric neuronal progenitor cells can enhance the survivability and maintenance of a stable

neurite outgrowth and neuronal differentiation.\",\n \"Laminin has long been known for its neurite promoting activity, in central, peripheral, and enteric neurons.\",\n \"The role of the heparan sulfate proteoglycan in neuronal differentiation is also well documented, both developmentally and in regenerative medicine applications.\",\n \"Fibrillar Collagen I was used additionally in these studies for ease of gelation and incorporation of other ECM components within a 3D hydrogel.\",\n \"Apart from composition, substrate elasticity has been demonstrated to affect the differentiation of adult neural stem cells, with neuronal differentiation reported between 100-500 Pa. ECM hydrogel compositions were adjusted in order to maintain their viscoelastic modulus within the range suitable for neuronal differentiation (FIG.\",\n \"10, table).\",\n \"Structural architecture was verified using scanning electron microscopy, wherein the addition of collagen IV demonstrated the presence of network structures, similar to self-assembled collagen IV in the mammalian basement membrane.\",\n \"The addition of laminin did not alter the ultrastructure, because it was expected to coat collagen fibers evenly.\",\n \"Additionally, laminin was also not expected to alter the stiffness/viscoelasticity of the gels, given the manner of its interaction with the collagen.\",\n \"The glycosaminoglycan chains of heparan sulfate are documented to cross link between laminin and collagen IV, thereby pulling fibers into a more compact structure, and slightly increasing the viscoelasticity of ECM gels.\",\n \"Smooth muscle cells within tissue engineered sheets drive the differentiation of enteric neuronal progenitor cells.\",\n \"Tissue engineered sheets provided a good modality to assess variability of differentiated neurons due to ECM composition as well as the functionality of differentiated neurons.\",\n \"The proximity to smooth muscle promoted the differentiation of enteric neuronal progenitor cells extensively.\",\n \"In vitro differentiation of neural stem cells in the presence of gut-derived factors has been demonstrated previously by us and others.\",\n \"Neurotrophic factors (NT-3, Neurturin, GDNF) and morphogens (BMP-2/4) capable of driving enteric neuronal progenitor cell proliferation and differentiation have been demonstrated to arise from the smooth muscle and mesenchyme of the developing and adult gut.\",\n \"Recently, the postnatal bowel was demonstrated to support the differentiation of enteric neuronal progenitor cells, strengthening the fact that cues for differentiation can be derived from the postnatal gut.\",\n \"Hence, it was expected that smooth muscle cells within the tissue engineered sheets would drive the differentiation of enteric neuronal progenitor cells.\",\n \"We evaluated all tissue engineered sheets to ensure that the constituent smooth muscle cells demonstrated a contractile phenotype expressing Smoothelin (FIG.\",\n \"14B).\",\n \"Smoothelin expression has been previously demonstrated to be essential for contractility of smooth muscle.\",\n \"In line with the equivalent expression of smoothelin, myogenic electromechanical coupling integrity was also equivalent in the tissue engineered sheets (FIG.\",\n \"14A-D) Similar patterns of contractions were observed in tissue engineered sheets in response to KCl, regardless of ECM composition.\",\n \"The ECM modulates differential neuronal subtypes while supporting overall smooth muscle-driven neuronal differentiation.\",\n \"In the presence of the smooth muscle, enteric neuronal progenitor cells differentiated, and expressed similar amounts of pan-neuronal marker βIII Tubulin (FIG.\",\n \"14A), suggesting that smooth muscle derived factors and substrate viscoelasticity were suitable for overall neuronal differentiation.\",\n \"However, on closer examination of neural subtypes, there was a differential expression of excitatory and inhibitory markers within tissue engineered sheets with varying ECM compositions (FIG.\",\n \"14).\",\n \"Sheets containing laminin had a balanced expression of both ChAT and nNOS.\",\n \"Kinetics of Ach-induced contraction in laminin sheets was most similar to native tissue, indicating the presence of an increased viable cholinergic neuronal component in composite collagen/laminin sheets.\",\n \"Furthermore, attenuation of EFS-induced relaxation by L-NAME (˜62%) was also kinetically similar to native tissue (˜78%), indicating the presence of a nitrergic neuronal component.\",\n \"Collagen I, in the absence of any other matrix components, was the ECM of choice when an enriched cholinergic neuronal population was required, with a significantly diminished nitrergic neuronal population (FIG.\",\n \"14C-D).\",\n \"While these sheets demonstrated a robust TTX-sensitive Ach-induced contraction commensurate with the heightened ChAT protein expression, relaxation in response to an electrical field was diminished.\",\n \"Furthermore, there was minimal attenuation of relaxation upon the inhibition of nNOS, correlating with the low nNOS expression.\",\n \"Substrates that supported cholinergic neuron differentiation may result in enriched populations of cholinergic

inhibitory motor neurons, respectively.\",\n \"The ECM microenvironment plays a role in modulating neurotrophic as well as morphogenetic signaling.\",\n \"Morphogenetic signaling via the BMP family expressed in fetal gut is important for the phenotypic diversity of enteric ganglia, including nitrergic and VIP-ergic neuron differentiation.\",\n \"Collagen IV is documented to modulate BMP signaling, and heparan sulfate modulates GDNF signaling in the gut.\",\n \"Immunoreactivity of neurotrophic factor, NT-3, has been observed in ganglia and in the ECM molecules surrounding them, suggesting a role for a Collagen IV-based ECM to modulate NT-3 signaling.\",\n \"The constituent smooth muscle phenotype in tissue engineered sheets was contractile, expressing smoothelin, and generating contractions and relaxations approaching ˜60% of those generated by native intestinal tissue.\",\n \"Differentiation cues arising from the constituent smooth muscle cells drove enteric neuronal differentiation.\",\n \"Furthermore, it is likely that the ECM could act as a framework for smooth muscle-derived factors, enhancing or inhibiting their effects, resulting in the generation

or without laminin/heparan sulfate) had a significantly higher nNOS expression ranging from 26.37±1.29 AU-28.15±2.69 AU.\",\n \"Conversely to ChAT, collagen I sheets had minimal nNOS expression (11.33±2.85 AU).\",\n \"Presence of nNOS was additionally confirmed using immunohistochemistry (FIG.\",\n \"13I-L).\",\n \"VIP-Ergic Inhibitory Motor Neurons: Vasoactive intestinal peptide (VIP) motor neurons were identified using immunohistochemistry.\",\n \"VIP neurons were abundant, with increased immunofluorescence in composite hydrogels with laminin and heparan sulfate (FIG.\",\n \"13A-D).\",\n \"Substrates that supported peptidergic neuron differentiation may result in enriched populations of peptidergic neurons comprising greater than 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 100%, or any intermediate percentage.\",\n \"Agonist Induced Contractility of Tissue Engineered Innervated Smooth Muscle Sheets Potassium Chloride-Induced Contraction: Electromechanical coupling integrity of constituent smooth muscle cells was first evaluated using potassium chloride (KCl).\",\n \"KCl treatment elicited rapid contractions that were sustained for ˜5 minutes (FIG.\",\n \"14).\",\n \"Peak maximal contraction in response to KCl was similar between the different tissue engineered sheets (FIG.\",\n \"14A-D), ranging from 279.5±4.79 μN to 296.5±6.26 μN.\",\n \"This correlated with the equivalent expression of contractile smooth muscle marker, Smoothelin, indicating that the constituent smooth muscle cells within the tissue engineered sheets maintained a contractile phenotype regardless of ECM composition.\",\n \"Furthermore, KCl-induced contractions in tissue engineered sheets were similar to native rabbit intestinal tissues (FIG.\",\n \"14E) in time course, but slightly reduced in magnitude.\",\n \"Peak KCl-induced contractions in native tissue averaged 373.5±10.63 μN.\",\n \"KCl-induced contraction was unaffected by pre-treatment with neuronal blocker TTX (grey traces; FIG.\",\n \"14), indicating myogenic electromechanical coupling integrity.\",\n \"FIG.\",\n \"16F demonstrates that the area under the curve of contraction was similar in all tissue engineered sheets, and was significantly higher in native rabbit intestinal tissues.\",\n \"Although reduced in magnitude compared to native tissue, KCl-induced contractions were similar among the different tissue engineered sheets, indicating a robust contractile smooth muscle phenotype unaffected by the ECM composition.\",\n \"Acetylcholine-Induced Contraction: Exogenous addition of 1 μM Acetylcholine (Ach) was used to simulate agonist-induced contraction.\",\n \"All tissue engineered sheets contracted in response to Ach, and sustained contractions up to ˜5 minutes post stimulation with Ach (FIG.\",\n \"15A-D).\",\n \"Tissue engineered sheets with composite collagen I/IV with laminin had a significantly elevated peak maximal Ach-induced contraction (FIG.\",\n \"15C; 232.9±8.167 μN), as well as an elevated area under the curve of contraction (47606±2054 AU).\",\n \"Magnitude of Ach-induced contraction was still significantly lower compared to contraction in native tissue (342.6±3.15 μN; 70448±5876 AU).\",\n \"However, the time course of contraction was very similar to native tissue in tissue engineered sheets containing laminin, reaching maximal contraction within a minute of agonist stimulation.\",\n \"Collagen I sheets also had an elevated Ach-induced contraction (FIG.\",\n \"15A; 238.9±13.72 μN; 42668±2172 AU) corresponding to the elevated ChAT protein expression.\",\n \"However, the kinetics of contraction did not match native tissue.\",\n \"In order to estimate the smooth muscle (myogenic) component of Ach-induced contraction, neurotoxin TTX was used as a pretreatment (grey traces, FIG.\",\n \"15).\",\n \"Area under the curves of contraction was compared with and without TTX pre-treatment in order to estimate % inhibition (FIG.\",\n \"15F).\",\n \"Percent inhibition of Ach-induced contraction in the presence of TTX was highest in two ECM conditions: i) collagen I sheets (72.77±2.45%); and ii) collagen I/IV/laminin sheets (60.58±1.66%).\",\n \"These values of % inhibition were similar to that observed in native tissue (72.73±3.66%) upon TTX-pretreatment.\",\n \"This increased neuronal contribution to Ach-induced contraction also correlated with the elevated protein expression of ChAT in collagen I and composite collagen I/IV/laminin sheets (FIG.\",\n \"12E, G).\",\n \"TTX-pretreatment inhibited Ach-induced contraction to a significantly lower extent in collagen I/IV±heparan sulfate sheets, ranging from 48.36±4.36% (Heparan sulfate) to 50.31±4.22% (collagen IV; FIG.\",\n \"15F).\",\n \"Relaxation in Engineered Innervated Sheets in Response to Electrical Field Stimulation: Electrical field stimulation (EFS) at 5 Hz, 0.5 ms was used to stimulate neurons within the tissue engineered sheets to produce relaxation of smooth muscle (FIG.\",\n \"16).\",\n \"The extent of relaxation was quantified as area under the curve of relaxation.\",\n \"Extent of relaxation significantly varied amongst the tissue engineered sheets with varying ECM compositions.\",\n \"Sheets bioengineered with collagen IV, which displayed elevated nNOS expression, had higher relaxation compared to sheets bioengineered with collagen I only (compare 109693±8465 AU in collagen I/IV sheets to 23142±4921 in collagen I sheets).\",\n \"Sheets containing laminin and/or heparan sulfate also had significantly elevated relaxation compared to collagen I sheets (68395-69025 AU).\",\n \"In response to EFS, native tissues relaxed generating 101550±11279 AU.\",\n \"Tissue engineered sheets with collagen IV and/or laminin and/or heparan sulfate additionally had a time course of relaxation most similar to native tissue.\",\n \"Maximal relaxation was achieved within 2 minutes of EFS, and a subsequent recovery of basal force was complete within 10 minutes.\",\n \"Upon pre-treatment with TTX, EFS-induced relaxation was inhibited entirely (grey traces, FIG.\",\n \"16).\",\n \"Inhibition of Nitric Oxide Synthase: In order to identify the presence and functionality of nitrergic neurons, an inhibitor of nitric oxide synthase (L-NAME) was used (grey traces, FIG.\",\n \"17).\",\n \"Percent inhibition was determined by comparing areas under the curves of maximal relaxation with and without the L-NAME pre-treatment.\",\n \"Percent inhibition with L-NAME treatment was the lowest in collagen I sheets (33.37±8.37%; grey trace, FIG.\",\n \"17A).\",\n \"This corresponded to the low protein expression of nNOS in collagen I sheets compared to sheets containing collagen IV (FIG.\",\n \"12D).\",\n \"In contrast, the inhibition of nNOS activity attenuated relaxation up to 61.71±2.82% (grey trace, FIG.\",\n \"17B) in collagen I/IV sheets.\",\n \"In sheets containing laminin and heparan sulfate, % inhibition with L-NAME varied between 62.28±2.75% (laminin, FIG.\",\n \"17C) to 57.16±1.91% (heparan sulfate).\",\n \"This inhibition is significantly elevated compared to collagen I sheets, corresponding to the increased expression of nNOS observed in the collagen I/collagen IV sheets (FIG.\",\n \"12C).\",\n \"Native tissues had a higher % inhibition with L-NAME (78.02±2.85%).\",\n \"Inhibition of the VIP-Receptor: The functionality of VIP-ergic neurons was assessed using a VIP receptor antagonist (VIP-Ra).\",\n \"Pre-treatment with VIP-Ra inhibited maximal relaxation in all tissue engineered sheets to varying extents ranging from 55.55±3.92%-65.92±5.38% (grey traces, FIG.\",\n \"18).\",\n \"Inhibition of EFS-induced relaxation indicated the presence of differentiated VIP-ergic neurons in

of Sound Propagation and Mixing in Air The experience of listening to digital audio recordings is improved by making subtle modifications to the recorded audio signals that simulate the linear and nonlinear effects of propagation and mixing of sound in air.","The mixing in a nonlinear medium of multiple or complex sound waves comprised of multiple frequencies is known as heterodyning.","Heterodyning may occur at various locations in the air, including at a speaker or at the user's tympanic membrane.","Because the speed of sound in air is itself dependent upon the particle velocity or pressure of the air at any given moment in time and position in space, air may not be a purely linear propagation medium.","For example, the compression peaks of an acoustic waveform may travel faster than rarefaction troughs, distorting the waveform and transferring energy into higher harmonics of the original signal.","When multiple or complex sound waves comprised of multiple frequencies propagate in such a nonlinear medium, the sound waves transfer energy into sound at new frequencies (e.g., intermodulation products) given by the sums and differences of the original signal frequencies.","While these nonlinear effects of air are generally subtle at auditory frequencies and typical sound pressure levels (SPLs) (e.g., loudness levels), second-order nonlinear effects may generate content at levels as high as only 30 decibels below the primary sound pressure and are often perceptible during live music performances.","These second-order intermodulation products have amplitudes proportional to a derivative of the products, which may result in intermodulation products or other propagation effects that increase with an increase in frequency.","Nonlinear propagation effects of audible frequencies may also interact with lower frequencies in an intermodulation scheme.","Thus, the nonlinear effects of air may play an appreciable role in how the brain processes and perceives sound.","The mixing signal processing technique may improve the ability of a system to reproduce the effects of a live performance using a digital audio recording.","While some music is experienced through live performance, most music is experienced through listening to stored analog or digital audio signals.","Digital audio signals are converted to analog signals using digital-to-analog converters, and the original or converted analog audio signals are reproduced acoustically by headphones, open-air loudspeakers, or other means.","The reproduced signals may contain unnatural content, as the reproduced signals represent recorded or synthesized waveforms that have not propagated through air or otherwise mixed in ways that are naturally encountered with live sound.","For example, many genres of music may use recording techniques known as “close-mic'ing” and “overdubbing,” often in combination.","These techniques may include minimal amounts of propagation and mixing in air, and may result in sterile recordings of sounds.","In close-mic'ing, microphones are placed in close proximity to the sound source.","Close-mic'ing can be used to capture direct sounds, while simultaneously reducing energy captured from other sound sources and reducing acoustic reflections occurring in the room where the recording is taking place.","In contrast to listening to live music at a range from 1 meter to tens of meters, close-mic'ing sound-source-to-microphone distances may range from about 10 centimeters for recording vocalists to 5 centimeters for recording amplified guitar or acoustic drums.","In each case, the recorded sound waveform may experience extremely little propagation in air, and therefore may not include effects generated by propagation associated with a similar sound source heard from a more natural listening distance.","When multiple musicians are recorded performing in a space at the same time, close-mic'ing may enable a mix engineer to control their relative volumes individually or apply special processing to a subset of performers.","While this isolation of sounds is useful during mixing, natural effects of nonlinear propagation and mixing in air evolve gradually over distance and may require up to tens of meters of propagation to fully develop, and close-mic'd recordings may fail to capture these natural effects of nonlinear propagation and mixing in air.","The recording technique of overdubbing may isolate individual sounds more than close-mic'ing, and may also fail to capture natural effects of nonlinear propagation and mixing in air.","In overdubbing, additional sounds are recorded and synchronized with previously recorded sounds in order to build a recording of a full ensemble or song gradually through summation of multiple individual recordings.","Because modern digital audio workstations make it easy to layer a large number of individual recordings, each instrument or performance that contributes to a song is recorded individually.","For example, performers may play an instrument while listening to previously recorded parts of the song or a timing cue (e.g., metronome), and may record each instrument or vocal component individually until every song component has been recorded.","These individually recorded song components may also be close-mic'd to avoid room reflections and capture an isolated audio recording (e.g., dry sound).","Through heavy use of these techniques, many modern recordings include numerous individual close-mic'd waveforms that are mathematically added together by a computer and have not propagated and mixed in air as they typically would have in a natural live performance.","In particular, digital audio waveforms that have been generated electronically or synthesized digitally may not have experienced any propagation or mixing in air.","These digital audio waveforms are an extreme example of modern recording practices, as they are completely isolated from the other sounds contributing to a song or sound mixture, and may include little or no additional content or imprint from the space in which they were recorded.","Furthermore, when these sounds are later reproduced acoustically, it is often in a setting that does not allow for the propagation distance or source SPL (sound pressure level) needed for the generated sound to experience the amount of nonlinear propagation normally incurred during live performances or large-scale concerts.","This is true for many home and car playback systems and listening environments, and is particularly relevant to headphones and earphones.","For example, headphone propagation distance of reproduced sound can be less than 6 millimeters, which may allow a recorded sound to propagate in air for 5 to 10 centimeters from source to microphone and then earphone to the tympanic membrane.","Additionally, headphones may use a lower source SPL, as little spreading or propagation loss occurs.","Because modern recording techniques and common listening settings reduce or eliminate nonlinear propagation effects often present and audible during live performances, it is beneficial to recreate these effects through digital signal processing so a more natural sound is provided by digital recordings in typical listening environments.","The acoustical sidebands created by sound heterodyning in air give an added spectral and harmonic richness to sound that is commonly absent from the modern listening experience and would be beneficial to reproduce digitally.","Additionally, it is desirable to impose some of the frequency-dependent attenuation that accompanies natural propagation of sound in air to restore a more natural tonal balance to close-mic'd recordings, and to improve simulation of nonlinear interactions between or among sound components as they propagate.","Beyond compensating for modern recording techniques and playback settings, the use of digital signal processing to simulate nonlinear propagation and mixing of sound in air may enhance the experience of listening to digital audio.","The nonlinearity of air is most pronounced when high sound pressure levels are present, and listeners often find that higher listening volumes provide a more compelling and immersive listening experience.","Digitally introducing the nonlinear effects that would have occurred at high playback volumes may make playback at lower volumes more exciting and enjoyable by simulating part of the experience of listening at high SPLs.","FIG.","2 shows a system 200 for simulating linear and nonlinear effects of propagation and mixing of sound in air according to various embodiments of the present subject matter.","System 200 may operate on one or more input signals in order to generate intermodulation products that would be generated naturally during acoustic propagation of one or more signals at a given peak sound pressure level and then mixing these products with the original input signal(s).","Additional linear filtering is imposed by the system before, during, or after this process in order to simulate the natural frequency-dependent attenuation of sound as it propagates through air.","System 200 may improve the listening experience by compensating for modern digital recording techniques and listening settings that reduce or eliminate the natural attenuation and nonlinear effects of sound propagation through air and by simulating high SPL playback of audio at lower volumes by introducing the nonlinear effects of sound propagation at high SPLs into the recorded waveform itself.","System 200 modifies source material in a transparent and potentially subtle way while not altering the creative content of processed recordings, making it suitable for application to all varieties of musical or audio content recorded and stored in digital form.","System 200 takes as its input one or more input signals (Xi) 210 that represent the amplitude of one or more audio waveforms over time.","In various embodiments, these input signals 210 are a series of digitally stored values representing the instantaneous amplitude of a band-limited waveform that has been sampled at regularly spaced moments in time.","Each input signal (Xi) 210 may have a corresponding primary sound pressure (P1) 220.The primary sound pressure 220 is provided to a processor 230 for calculation of a secondary soundfield.","Processor 230 is a general purpose processor, a dedicated digital signal processing (DSP) integrated circuit (IC), or another type of processor suitable for the calculation of the secondary soundfield.","The output of processor 230 includes a secondary sound pressure (P2) 240, where the secondary signal 240 may simulate effects that would have occurred at high playback volumes to simulate a live mixing of the various sounds.","Primary and secondary sound pressures 220 and 240 are combined through superposition within an adder 250.Adder 250 includes a digital adder circuit or a summing amplifier and may include additional summation or timing components.","For example, processor 230 may introduce a delay in the secondary signal 240 relative to the primary signal 220, and adder 250 may include a fixed time delay or a synchronization module to detect the delay of the secondary signal 240.Adder 250 may combine primary and secondary sound pressures 220 and 240 to provide a sound pressure output signal (Yi) 260, where output signal 260 may simulate what the listener would hear at a live event.","System 200 may modify the input signal(s) in a manner dependent upon one or more controlling parameters.","Generally, these parameters define physical attributes of the simulated sound propagation and mixing and thus directly influence the formulas used to calculate the intermodulation products generated by the nonlinearity of air.","Alternatively, higher-level parameters are used to control the overall character or extent of the processing.","In some embodiments of the subject matter, these parameters are determined automatically through an additional mathematical analysis of the input's auditory content and the application of a rule or decision system that links analyzed signal content parameters to control parameters.","Because digital audio signals generally contain complex waveforms comprised of multiple frequency components and are applied during the mixing of multiple recorded sounds, the present subject matter in various embodiments uses quasi-linear solutions of Westervelt's general inhomogeneous wave equation to determine the relationship between input signals and generated intermodulation products.","In one embodiment of the subject matter, the Westervelt equation for second-order mixing, ∇ 2 P 2 - 1 c 0 2 ∂ 2 P 2 ∂ t 2 = - ρ 0 ∂ q ∂ t , ( 1 ) is used to capture the second-order intermodulation products generated by the nonlinearity of air, as these are generally the most prominent of intermodulation products.","In equation (1), secondary sound pressure (P2) 240 is the pressure variation associated with the intermodulation products generated by the nonlinearity of air, (ρ0) and (c0) represent the density and small-signal sound speed of air, respectively, and (q) is the virtual source density given by q = β ρ 0 2 c 0 4 ∂ ∂ t P 1

interaction angle of component sound fields if the primary sound pressure may be a mixture.","The general solution to differential equation (2), which can be used by one embodiment of the presently disclosed subject matter, is P 2 = - ρ 0 4 π ∫ V ∂ q ∂ t e ik s r ′ r ′ dV , ( 3 ) where (ks) is the wavenumber corresponding to an intermodulation product, (V) is the interaction volume over which the primary sound pressure has sufficient amplitude to contribute to the generation of intermodulation products, and (r′) is the distance from each virtual source point in the interaction volume (V) to the location where the generated secondary field is observed.","In this exemplary embodiment, the primary sound pressure (P1) 220 is comprised of either the single input signal (Xi) 210 or a combination of M individual input signals (Xi) 210, where i=1, .",".",".",", M. Parameters of equation (3) such as the definition of the interaction volume V, the radiation pattern of the sources (if multiple inputs may be being mixed), and the physical sound pressure level being simulated is specified, either directly by a user, based on higher-level specifications, or by some other means, and a solution for the secondary sound field P2 is calculated.","An interaction volume (V) with a single isotropic source is shown in FIG.","3, and an interaction volume (V) with two isotropic sources is shown in FIG.","4.FIG.","3 demonstrates a single-source spatial representation 300 of an interaction volume, according to one embodiment of the present subject matter.","In particular, FIG.","3 demonstrates calculation of the secondary sound pressure (P2) 240 generated by a complex (multiple-frequency) primary sound pressure (P1) 220 radiating from a single isotropic source due to the nonlinear effects of propagation in air.","The single-source representation 300 may include a single isotropic source 310, where the isotropic source 310 represents sound generated using primary sound pressure (P1) 220.The isotropic source 310 may generate an interaction volume (V) 320 as used in equation (3), where interaction volume 320 is the volume over which the primary sound pressure contributes to the generation of intermodulation products.","A virtual source point 330 is selected, where the virtual source density at virtual source point 330 corresponds to virtual source point (q) in equation (2).","An observation point 340 is selected, where the distance from virtual source point 330 in the interaction volume (V) 320 to observation point 340 corresponds to the distance (r′) in equation (3).","FIG.","4 demonstrates a dual-source spatial representation 400 of an interaction volume, according to one embodiment of the present subject matter.","In particular, FIG.","4 demonstrates one method of calculating secondary sound pressure (P2) 240 due to the nonlinear effects of propagation in air, where the secondary sound pressure (P2) 240 can be generated by mixing of two independent isotropic sources.","The single-source representation 400 may include a first isotropic source 410 and a second isotropic source 415.The first and second isotropic sources 410 and 415 may be generated using primary sound pressure (P1) 220.The isotropic source 410 may generate an interaction volume (V) 420 as used in equation (3), where interaction volume 420 may be the volume over which the primary sound pressure contributes to the generation of intermodulation products.","A virtual source point 430 may be selected, where the virtual source density at virtual source point 430 corresponds to virtual source point (q) in equation (2).","An observation point 440 may be selected, where the distance from virtual source point 430 in the interaction volume (V) 420 to observation point 440 corresponds to the distance (r′) in equation (3).","For the interaction volume (V) shown in FIG.","3 and FIG.","4, the sound field may be comprised of the sum of second-order intermodulation products.","The sound fields represent sums and differences between pairs of frequencies present in the input signals.","The sound fields also represent second harmonics of all frequencies present in the input signals, each with amplitudes that may be proportional to the square of their frequencies.","Whether using one, two, or more isotropic sources, sound pressure output signal (Yi) 260 may be formed by mixing the secondary sound field (P2) 240 with input primary sound pressure (P1) 220 to arrive at the total sound field that would be observed in air.","The naturally occurring relative amplitudes of the primary and secondary sound fields 220 and 240 may be given by the solution to equation (1).","The sound pressure output signal (Yi) 260 may be further controlled by additional parameters, either interactively by a user, automatically according to analysis of the input signals 210, or by other means.","Linear filtering may be used to simulate frequency-dependent attenuation of sound as it propagates through air.","Linear filtering may be applied to the input signals 210 before or after calculating output signal 260, depending on computational considerations and other design choices.","Characteristics of such linear filtering may be selected to simulate or reduce attenuation properties of air.","The present subject matter applies the Westervelt equation to audible frequencies to compensate directly for modern recording techniques or simulate accurately the effects of high SPL playback of digitally recorded audio to enhance the listening experience.","Typical uses of the Westervelt equation deal with ultrasonic sound.","Most applications, such as high-intensity focused ultrasound and industrial applications of ultrasound, such as cleaning and welding, may be very different from that of the presently disclosed subject matter.","The Westervelt equation has been used in the field of parametric acoustic arrays, such as in the analysis and design of systems that generate beams of ultrasonic sound in order to produce directionally controllable content at audio frequencies through the nonlinear interactions of these ultrasonic beams in air.","Because the nonlinear effects of air increase with frequency, these effects may be strongly present at ultrasonic frequencies, but may be subtle at audio frequencies.","As a result, mathematical application of these nonlinearities to date has focused on ultrasonic applications, and not on digital audio waveforms with content only in the auditory band for enhancing listening during playback.","Additional methods may be used to simulate intermodulation products generated by audio-band sound due to the nonlinearity of air.","A reduced solution may include second-order effects and intentionally exclude higher-order intermodulation products.","Because of the generally low amplitudes of higher-order intermodulation products generated at reasonable SPLs at audible frequencies, the second-order embodiment discussed above may be sufficient to achieve the desired results, however other embodiments are possible.","In some cases, particularly when simulating very high source SPLs or when input waveforms have particular spectral properties, the calculation of higher-order intermodulation products may be desirable.","Higher-order calculations may be included in an embodiment of the subject matter if deemed necessary by a user or through analysis of the input signal.","Digital Signal Processing of Priming Signal for Reduction of Stress in the Auditory System A priming signal processing technique modifies digital audio recordings to reduce the stress experienced by a listener's auditory system.","A priming signal may reduce the instantaneous stress experienced by the auditory system during sudden changes in signal energy.","The priming signal may be generated such that pre-signal priming additions may not result in obvious differences in perceived sounds, thereby leveraging temporal auditory masking.","A method for processing digital audio signals in order to decrease the stress experienced by the auditory system of a listener without overtly changing the creative or musical content of the signal may be disclosed.","The method consists of an adaptive, time-varying system that responds to characteristics of input signal content according to a rule system, and that alters the signal either by mathematical convolution with one or more response templates or by the momentary addition of noise-like signals.","Unlike existing audio processing techniques, this method may not be intended to generate obvious audible differences in the content of an audio signal, but rather to cause an appreciable difference in the comfort and enjoyment of the listener by conditioning the signal to interact more gently or naturally with the listener's auditory system.","This method may be designed to compensate either directly or indirectly for the deleterious effects of unnaturally synthesized, mixed, or recorded digital audio signals as well as other potential shortcomings of digital audio formats and reproduction.","Due to its ease of implementation, this method may be suitable for application to all varieties of musical or audio content recorded and stored in digital form.","Synthetic generation of acoustic waveforms provides extensive creative opportunities.","However, synthetic waveforms also present the listener with audio material that defies many properties of natural sound.","Because these synthetic waveforms do not adhere to physical laws that the auditory system may be designed to understand, this defiance may cause stress on the human auditory system in processing and interpreting these signals.","While the creative freedom afforded by these signals should not be diminished, it may be desirable to introduce processing that may compensate for differences between expected and experienced characteristics of sound.","Such compensation may allow creation of a more enjoyable listening experience without significantly altering the creative content of the audio.","Furthermore, it may be generally desirable to process audio signals in ways that reduce the stress experienced by a listener's auditory system, whether or not such stress reduction may be achieved by imitating the natural behavior of sound.","There may be many known phenomena in the human auditory system that may be relevant to the present discussion.","At a high level, humans may be able to derive much information about their surroundings from analyses of patterns of reflections or multiple arrivals of the same acoustic signal.","For example, the auditory system may be able to use the filtering and delay imposed by the shape of the human head and ears (e.g., head-related transfer functions) to determine the direction from which a sound originated.","Reflections of a sound arriving after the initial direct path may be used by the auditory system to understand characteristics of the space surrounding a listener such as whether or not it may be enclosed, how distant nearby walls or other solid or semi-solid surfaces (such as groves of trees) might be, and the types of materials present in the surroundings (hard and reflective or soft and absorbent).","Such reflections can also be used to understand the location of a sound source relative to the listener: the pattern of reflections that arrives at a listener varies with changes in the relative locations of the listener and the source, creating auditory cues for distance and obscuration.","All of this high-level auditory information may be derived instinctually, without conscious training or attention, and may be based on the auditory system's understanding of how sound naturally interacts with its environment.","The majority of cues for this understanding may be contained in filtering and arrival patterns during the first 100 milliseconds or so after a direct signal, and our ability to make sense of these cues indicates a specialization of the human auditory system for processing naturally occurring audio signals.","At a lower level, it may be known that a wide range of similar acoustic signals may be perceived to present the same sound.","Although the human auditory system may be complex and not fully understood, this phenomenon has been studied extensively and may be known as auditory masking: the process by which the presence of one sound can render another sound imperceptible.","This effect may be a result of both the mechanics of the human peripheral auditory system, which transduces acoustic energy into electrical neural activity, and higher level processing performed in the central auditory system.","Acoustic energy may be transduced into neural activity in the cochlea by inner hair cells, which release neurotransmitters in response to mechanical deflection and incite action potentials (e.g., electrical spikes) in the primary auditory neurons.","Various encoding schemes, such as first-spike latency, rate-based coding, and detailed temporal codes may be then employed by the auditory system to transmit and analyze these initial excitations.","Stated simply, if a dominant sound may be already exciting a particular group of neurons, it may prevent a weaker sound that would excite the same neurons from being perceived.","This may be known as simultaneous masking.","Additionally, because much of the processing performed by the central auditory system involves integration of neural spike signals over some duration of time and because the human auditory system may temporarily decrease its sensitivity to sound in reaction to loud stimuli, masking can extend over a duration of time: a loud sound may render quieter sounds immediately preceding it or immediately following it imperceptible, with an influence that extends longer afterward than before (approximately 20 milliseconds before and 100 milliseconds after a loud sound, with influence decaying exponentially away from the time of the sound).","This may be known as temporal masking.","Finally, because each point along the length of the cochlea may be tuned to a specific frequency, sounds that may be similar in frequency may primarily excite the same groups of neurons, and may be more likely to mask one another through either type of masking.","This phenomenon of auditory masking means that it may be possible to make significant modifications to an audio signal which do in fact present the human auditory system with a different stimulus but which do not yield obvious differences in the content of the signal.","This may be the principle that underlies lossy compression schemes for digital audio such as the ubiquitous .mp3 standard, which may be designed to throw away a large portion of the information contained in an audio signal without changing the way that it sounds to a listener.","Here, this principle may be exploited to apply processing which has an appreciable effect on the listening experience without obviously altering the auditory system's interpretation of the processed data.","The present system analyzes and modifies this input signal; the exact modification performed on the signal at any given time may be dependent upon the current analysis output, and may vary with momentary changes in characteristics of the input signal.","In various embodiments, two main methods of modifying the input signal may be employed.","One of these methods may be to modify the input signal by performing the mathematical operation of convolution using the input signal and one or more convolution template signals.","The other method may be to introduce additional, momentary noise-like components into the output signal.","Digital Signal Processing of Priming Signal: Methods of Modifying the Input Signal FIG.","5 illustrates an embodiment of a signal-modification processing subsystem 500 for introduction of a priming signal, according to various embodiments of the present subject matter.","Subsystem 500 may take multiple input audio channels (Xi) as input 505, where input 505 represents the amplitude of an audio waveform over

delay the input signal by the maximum pre-signal convolution response time, effectively achieving look-ahead into the future of the input signal so that priming signal content may be added just prior to audio transients or other events.","Control data 530 may provide control inputs to a look-ahead amplifier 560, which may amplify or attenuate the signal from the look-ahead delay 540.Subsystem 500

configuration shown in FIG.","11 or 16.In the embodiment illustrated in FIG.","11, multiple audio channels may be analyzed individually by parallel single-channel analysis systems, the output of which may be further processed by a higher-level multi-channel analysis system that may lead to modifications of the resulting single-channel control decisions.","In the embodiment illustrated in FIG.","16, each type of signal analysis may be performed on a multichannel collection of signals at once, and the results from each type of analysis may inform other analyses.","FIG.","6 illustrates an embodiment of an FIR convolution subsystem 600, according to various embodiments of the present subject matter.","FIR convolution subsystem 600 may take an audio channels (Xi) as input 610.Audio input

As shown in FIG.","5, this dry signal may be implemented as a parallel signal and does not enter a convolution subsystem, such as using parallel channel look-ahead delay 540 shown in FIG.","5.Because this parallel input dry signal may be delayed, template content that occurs at lags smaller than this dry-signal delay may be added effectively to the output in response to input signal content that has not yet appeared at the processing system's output.","This portion of the convolution template reacts to future input signal and may result in the addition of content to the output signal just prior to audio events such as transients.","FIGS.","8A-8B illustrate enforced zero-response examples 800A-800B around the dry signal delay time according to various embodiments of the present subject matter.","Each of example waveforms 810, 820, 830, 840, 850, and 860 depict a different application of a zero-response signal applied to the input signal 710 shown in FIG.","7.Example waveforms 810, 820, 830, 840, 850, and 860 depict a duration of silence enforced in the convolution templates around zero delay, or the point in time corresponding to the current input signal amplitude, given as ci[n]=0,n=pMAC−k, .",".",".",",pMAX+l (7) for some numbers of samples (k) and (l).","Values (k) and (l) may be selected to minimize the alterations of the way that the input signal sounds.","FIG.","8A includes example waveforms 810, 820, and 830, which depict a symmetric short duration of silence enforced in the convolution templates around zero dry-signal delay tpMAX=10 ms.","Example waveform 810 shows a small duration of silence, example waveform 820 shows a medium duration of silence, and example waveform 830 shows a large duration of silence.","Example waveforms 810, 820, and 830 depict an asymmetric short duration of silence enforced in the convolution templates around zero delay.","FIG.","8B includes example waveforms 840, 850, and 860, which depict asymmetric short duration of silence enforced in the convolution templates.","In particular, waveform 840 depicts an asymmetric duration of silence beginning at dry-signal delay tpMAX=10 ms, example waveform 850 depicts an asymmetric duration of silence around tpMAX=10 ms, and example waveform 860 depicts a large asymmetric duration of silence around tpMAX=10 ms. A system may select one of symmetric or asymmetric example waveforms 810, 820, 830, 840, 850, and 860, and therefore select the delay and position of silence, in order to reduce the perception of the artificial duration of silence.","In natural acoustic environments, the sound heard by a listener may be always the combination of an initial direct-path arrival followed by subsequent early reflections.","In nearly all cases, this leaves duration of silence (for example on the order of milliseconds) in the room response between the initial first arrival and the first-arriving reflection.","Although the details of this first-arriving reflection and other soon-arriving early reflections may vary greatly with the positions of a sound source and listener or the acoustic space in which they reside, these changes in response generally do not alter the observed character of a sound in an obvious way.","For example, a particular sound source such as an instrument or a particular person's voice may be recognizable in a wide variety of spaces from a small, enclosed room to a huge cathedral; the sound identified as being produced by the source does not change significantly in character, despite the fact that the sound associated with the space it may be in changes drastically.","This may not be to say that such responses cannot contribute to the perceived character of a sound, but to demonstrate that many convolution templates with some duration of silence trailing the zero-delay component may be expected to yield subtle effects on the sound being processed; in fact, recording engineers often put significant effort into choosing the placement of microphones such that a pleasing portion of a source's radiation pattern and initial reflections may be captured during recording.","This convolution template design technique may apply this subtlety and correspondence to naturally occurring sound phenomena.","While convolution responses longer than approximately 50 milliseconds in duration may be perceived temporally by the human auditory system, convolution responses shorter than this may be heard spectrally in that they tend to alter the perceived character of the sound being convolved with the response rather than introducing new, separate sounds.","The effect of summing multiple, repeated copies of a single signal on that signal's spectrum may be known as comb-filtering.","In comb-filtering, a series of evenly spaced frequencies may be cancelled in the signal's spectrum because the contributions from the multiple delayed copies of the input signal at those frequencies may be out of phase and sum to zero.","In general, this type of comb-filtering may be largely imperceptible to humans (although particular types of comb-filtering that change systematically over time do, however, form a class of obvious audio effects known as flanging and phasing).","The fact that this type of filtering does not create blatantly obvious changes in the character of a sound may be likely because it may be so commonly encountered in natural acoustic spaces, as discussed above.","By enforcing a period of silence around the zero-delay component of convolution templates and applying otherwise subtle or low-level responses, the frequency response of the templates tends to occupy this space of comb-filter-like responses that alter the character of the filtered sound in only subtle ways.","In addition to this convolution-based method of modifying the input signal, the input signal may also be modified through the momentary addition of specific noise-like signals, y-noise.","These noise signals may be added at times determined by the results of the input signal content analysis, such as during or slightly before transient peaks.","This novel procedure may be intended to achieve the goal of auditory stress reduction in a manner similar to that of pre-signal content in convolution templates: the addition of a specific noise-like signal may be designed to prime the auditory system for sudden changes in signal energy and to soften the momentary auditory stress induced by sudden changes in signal energy.","Again, due to the phenomena of temporal and simultaneous masking, such additions may not be expected to result in obviously different sounds, despite the fact that they may present a listener with markedly different acoustic signals.","In some embodiments of the present subject matter, the addition of filtered noise may seem analogous to processing performed by generalized lossy perceptual audio compression schemes.","Lossy perceptual audio compression techniques can generally be interpreted as adding spectrally shaped noise to recorded digital audio signals that may not be readily audible.","However, this interpretation may be based on a typical method for analyzing the results of quantization and does not fully describe the processing performed by such systems.","In practice, these systems quantize information about the input signal such as its spectrum during successive blocks of time with varying resolutions, which may result in highly objectionable audible artifacts and correlations between the input signal and resulting quantization error that cause the additive-noise based interpretation to be inaccurate.","Furthermore, when considered as adding spectrally shaped noise to the recorded digital audio signal, these compression technologies add broadband noise over the full duration of the audio signal.","In contrast to generalized lossy perceptual audio compression techniques that seek to decrease the amount of data required to represent the digital audio signal, this method may be used to improve the experience of listening to an acoustically reproduced version of the audio signal.","To improve the listening experience, specifically shaped noise sequences may be added to the input signal only at specific noise times and for specific noise durations in order to decrease the stress experienced by the auditory system at those moments, where the noise durations may make up a small portion of the duration of the input signal.","This use of additive noise also differentiates it from simulations of tape or vinyl mediums that introduce noise during the full duration of an audio signal in order to simulate properties of those recording media.","Digital Signal Processing of Priming Signal: Automatic and Signal-Aware Control of the Modification Methods In various embodiments, the modification operations discussed above may be controlled automatically by the results of signal content analysis performed on the input signal.","This analysis aims to assess four main characteristics of the input signal: the distribution and complexity of its momentary spectral content, the program, or average, perceived loudness of the signal, the presence of transient bursts of energy or changes in signal content, and, when used on multi-channel recordings, the spatial relationships of these characteristics across the multiple channels.","The results of these analyses in turn drive a rule-based control system that may be designed to provide processing that, at any given moment, reduces the stress experienced by the auditory system of a listener while remaining transparent and not obviously audible.","In exemplary embodiments of the subject matter, this rule-based control system may consist of a digitally stored look-up table, a set of parameterized functions, or a combination of the two, which relate the outputs of the analysis subsystems to the operation of the modification system components.","While in general this control of the modification processes may be performed without intervention from a human operator, in one exemplary embodiment of the subject matter an operator or application that uses the presently disclosed subject matter may specify one or more high-level operation control parameters prior to applying it to a digital audio signal.","Such high-level parameters may describe the kind of content being processed or the type of playback system that may be used to listen to the generated output signal.","With the caveat that higher-level specifications may adjust the interpretations of each analyzed signal characteristic, we may now describe how the outputs of these signal characteristic analyses may be used to control the signal modification processes.","Due to the frequency-dependent nature of many auditory processing phenomena such as masking, analysis may be performed to determine the distribution and complexity of the input signal's momentary spectra.","This analysis, in turn, guides the determination of which convolution templates to use as well as the relative mixing gains applied to the outputs of each convolution, and, when deemed appropriate by other analyses, the type of noise signal to add to the input.","Convolution templates and noise signals may be chosen to complement the current input signal content and to avoid creating obvious audible effects.","Modifications that introduce too much content at frequencies that may not be strongly present in the input signal or that may become obvious due to simple, non-complex material may be avoided.","Because the behavior of the human auditory system may be non-linear and generally responsive to relative changes in energy levels, the analysis system estimates the program level, or the average perceived loudness, of the input signal over time.","For most audio signals, this estimate may vary gradually with changes in signal content.","Relative changes in program level or comparisons between the estimated program level and the known average program level of typical audio recordings (which may vary with the genre of music or type of content contained in the audio signal) may then be used to guide control of the input signal modification system.","For example, characteristics such as the pre-signal lead-time used by convolution templates, the relative amount of processed signal mixed with the raw input signal, and the choice of convolution templates may all be affected by the estimated program level.","Audio transients, or short-duration changes in audio signal energy or spectral content, provide a particular kind of stimulus to the human auditory system that requires special processing by the input signal modification system.","In order to enable such special processing, the input signal may be analyzed to detect transient events in the audio stream.","Once detected, a transient event may be further analyzed for relative energy content, spectral make-up, and duration.","Among other things, the detection of these events may control the choice of convolution templates and corresponding mixing gains, the amount of pre-signal lead-time used by the convolution templates, the addition of momentary noise-like signals to the input signal, and the enforcing of a duration of silence around the zero-delay time in convolution templates.","Finally, because digital audio signals may be commonly reproduced on multichannel systems (with stereo, or 2 channel, systems being the most common), an awareness of the spatial image created by multiple signals may be required to avoid introducing changes into the individual audio signals that result in obvious or undesirable effects, where the changes may be perceived when a user listens to the combined output signals through such a multichannel system.","When processing audio signals intended for multiple-channel playback, all channels may be processed together.","A higher-level analysis that takes as its inputs the single-channel analysis results may be performed, and the output of this higher-level analysis may be used as an additional control input to the single channel modification systems.","The result may be that different modifications may be made to each individual input signal than would have been made were the input signals processed in isolation; the control of the modification system must respect an additional set of rules to ensure that the interaction between multiple channels during playback does not have undesirable effects.","Digital Audio Processing for the Restoration of Motion and Dynamic Timbre The sense of motion, liveliness, and spatial dynamics may be simulated using various methods discussed in this document.","These methods may compensate for the static presentation of sound created by modern recording and sound synthesis techniques and common modern playback equipment such as headphones and ear buds in order to create a more natural, immersive, and enjoyable listening experience.","Modern recorded music and sound, unlike naturally produced acoustic sound, may be spatially and timbrally static.","Perhaps the most pervasive recording technique in modern audio production may be to record musical performances in a close mic'd manner, meaning that one or more microphones may be placed at static positions close to a musician or sound source and a performance may be recorded with minimal motion being made by the musician in order to produce a consistent loudness and tone across the duration of the recording.","While this technique may afford a certain precision in the recording and post-processing of each musician's contribution to a song or musical piece, it deprives the completed recording of the liveliness and timbral dynamics created by motion in more natural performance and listening environments.","The use of digitally synthesized sounds in modern recordings can take this dry, static nature to an extreme, producing recorded sound that may be entirely unchanging in tone or character over time.","These modern recording techniques and technologies give rise to an unnatural and unpleasant stationary-tone audio-reproduction environment (STARE), in which recorded sound may be experienced as both spatially and timbrally static.","In contrast, when performers play together in an acoustic space their movement alters the spatial radiation characteristics of their instruments over time, gradually changing the timbral qualities of their instruments and exciting various resonances and reflections in the space where they may be performing.","Additionally, motion of performers on a stage or of listeners in an audience may change the sound heard by everyone in the audience in small or obvious ways.","Even subtle motions of an audience member's head may create shifts in the delays and filtering experienced by the various sound components reverberating about a space before reaching their ears, and thus alter the tonal and spatial qualities of the sound that they hear.","All of these dynamic effects contribute to a sense of immersion and liveliness that may be desirable to reproduce when listening to recorded audio.","Although post-processing of close-mic recorded audio may add reverberation or panning effects that help to approximate this feeling of immersion and motion, these effects still present a sound with static tonal and spatial qualities in the sense that we have discussed here: a sound may be made to occupy some space or originate from some direction, but none of the natural, motion-driven variability that we have discussed here may be restored.","Certain pieces of revered and highly sought-out analog recording equipment may come closest to providing an existing remedy for this problem of static recorded sound, as such equipment may be known to create subtle, time-varying changes in the tone and imaging of processed signals due to circuit phenomena such as very-low-frequency shifts in the DC-bias points of internal components caused by transient offsets in audio signals; however, this type of equipment may be expensive and thus may not be available to all producers of recorded music.","Furthermore, such currently existing equipment may only provide a portion of the variability and dynamics that may be desirable for the re-creation of natural sound environments and the maximization of listening enjoyment.","With the rise of portable music devices and the accompanying increase in the usage of portable playback equipment such as headphones and ear buds, the STARE problem has been taken to an extreme over the past decade: unlike loudspeakers, these personal playback devices prevent even the natural variability in tone that may be associated with a listener moving about a room or turning their head.","At the same time, the popularity of close-mic recording techniques and synthesized digital audio has shown no signs of recession.","Thus, it may be desirable to introduce digital signal processing techniques that restore a sense of motion and liveliness to digital audio recordings in order to improve the experience of listening to modern digital audio.","A method for processing digital audio signals in order to restore a natural sense of motion and liveliness may be disclosed.","The method consists of analyzing a digital audio recording and applying time-varying phase shifts, inter-aural delays, filtering, and amplitude and frequency modulation (e.g., “flutter,” “wow”) in a subtle way that may be driven by the presence of particular signal characteristics, such as percussive or transient events, that help to make the applied processing non-obvious.","This method may compensate for the static tonal and spatial listening experience created by modern recording techniques, digitally synthesized sounds, and popular personal playback devices such as headphones and ear buds.","This method may improve the experience of listening to digital audio recordings by restoring a sense of motion and immersion to those recordings that may be commonly experienced in live acoustic settings.","FIG.","9 illustrates an exemplary multichannel analysis signal-modifying processing subsystem 900, according to various embodiments of the present subject matter.","Subsystem system architecture 900 demonstrates the general system architecture, consisting of a signal-analysis and processing-control subsystem and a signal-modifying processing subsystem, each of which may handle multiple input signals 910.The system takes one or more input signals 910 that each represent the amplitude of an audio waveform over time.","Typically, these signals may each be a series of digitally stored values representing the instantaneous amplitude of a band-limited waveform that has been sampled at regularly spaced moments in time.","The signal-modifying processing subsystem 900 both analyzes and modifies these input signals 905, with the results of input signal analysis determining the modifications to be performed at each point in time.","In general, any available data may be analyzed and used to determine the exact modifications to be made to the digital audio signals at each point in their durations, though the presence of transient changes in intensity or energy associated with percussive sounds may play a large role in determining when modifications may be to be made because such sounds have the ability to help mask the applied modifications and make them non-obvious.","Each channel in a multichannel processing system, from channel one 920 to channel N 925, may include multiple processing blocks.","For example, channel one 920 may be processed through a frequency-dependent phase shift processing block (e.g., all-pass cascade processing block) 930, a linear relative-delay block 940, a magnitude filtering block 950, and an amplitude and frequency modulation block 960.Each processing block may be modified by control data 970, where control data 970 controls processing parameters within each processing block.","Processing may be governed by parameterized equations that relate numerical results of signal analysis to parameters controlling the signal modification algorithms.","The output of the processing blocks for each channel may be output from the subsystem 900 as output analysis results 980.Additionally, output analysis results 980 may be used to select a particular modification algorithm from a collection of available, implemented algorithms for use on a particular signal or time-region of a signal through some logical or rule-based processing of output analysis results 980.Implementation of the relationship between signal analysis and modification may be controlled or adjusted by higher-level parameters to select a particular relationship from a collection of options: for example, a high-level analysis of the input signals may determine the type of audio content that may be currently being processed (a general, individual instrument or some identified particular instrument, a complex sound mixture of multiple instruments, a sound mixture identified to belong within a particular genre of music, etc.)","and use this determination to choose a particular relationship between analysis output and modification from a collection of relationships that may be each most appropriate for a certain type of content.","Such high-level control and any lower level parameters of the relationship between analysis and modification may be exposed to an end-user through some type of interface for manual adjustment, or may be performed automatically.","Once an analysis configuration and relationship between output analysis results 980 and signal modifications has been determined, time-varying modifications may be made to the input signals 910 to create a sense of motion and liveliness in the recorded audio, thereby improving the experience of listening to it during subsequent playback.","These modifications may be performed in a way that may be subtle enough to avoid being overtly noticeable by listeners and that may be neutral enough to avoid altering the creative content of the audio recording, while still creating an appreciable, pleasing effect.","Significant motion effects may be achieved within the all-pass cascade processing block 930.The all-pass cascade processing block 930 may introduce time-varying, frequency-dependent phase shifts, potentially applying different shifts to each channel in a stereo or multichannel recording.","Such modifications can be performed using digital all-pass filtering, using filters with transition frequencies and orders that vary over time.","It has been demonstrated in psychoacoustics experiments that the effects of such phase shifts, which correspond to sound components moving closer and further away, can be perceptually subtle when compared with magnitude, or non-all-pass, filtering.","To reduce the perception of the phase shift, a bandpass filter may be used to avoid shifting the phase of the bass or treble.","The bandpass filter may include frequencies ranging from 500 Hz to 5 KHz.","This provides a neutral and subtle way of animating sound content.","In various embodiments of the presently disclosed subject matter, changes in imposed phase shift may often occur in-sync with percussive audio transients, with the amount of shift increasing during transients and then slowly drifting back toward zero over the course of approximately 200 to 500 milliseconds, or in a semi-periodic cyclical fashion at a similar rate.","The linear relative-delay block 940 may modify digital audio recordings in order to instill a sense of motion may be using time-varying inter-aural delays.","When a sound source moves about a space relative to a listener or a listener rotates their head relative to a source, varying amounts of delay may be experienced by sound as it travels to the listener's left and right ears.","Because of this, applying small, time-varying amounts of relative delay between the left and right channels of a stereo audio recording or among multiple channels in a multichannel recording can create a sense of movement and variability similar to the motion that naturally occurs when listening to a live performance.","Because listeners have been found in psychoacoustics experiments to be able to detect horizontal displacements of less than one degree in the horizontal plane, the relative delays imposed by the modification system in this way need not be large in order to create a sense of motion.","In fact, using too large a modification may be likely to be distracting and prevent the desired subtlety.","Various embodiments may impose time-varying relative linear delays of approximately 0.1 millisecond or less across channels in a stereo or multichannel recording.","As with imposed frequency-dependent phase shift, the amount of applied relative linear delay may vary in-sync with percussive or transient audio events, or may oscillate in a semi-periodic fashion that may be more loosely driven by signal properties.","The magnitude filtering block 950 may be used to simulate a radiation pattern corresponding to motion of an audible source or listener.","The radiation pattern of a sound source may change in response to the motion of performers around it or the way that a performer makes contact with it, and the transfer function from a source to a listener due to the acoustic space that they occupy may change significantly as either person moves about or rotates within the space.","Typically, these phenomena may give rise to general changes in timbre that may be simulated using low-order IIR (infinite impulse response) filters with transition or cut-off frequencies and gains that change over time or comb-filtering effects caused by the summation of multiple reflections of sound that can similarly be modeled using digital FIR (finite impulse response) or IIR filters that change over time.","Both of these types of filters may be designed to produce subtle effects, and thus provide the types of modification desired by the presently disclosed system; by varying their application in response to characteristics of the input signal, such magnitude-filtering may be performed in a way that creates a sense of motion and liveliness without becoming obvious or altering the creative content of the modified recording.","The amplitude and frequency modulation block 960 may be used to impose subtle time-varying amplitude modulation (e.g., “wow”) and frequency modulation (e.g., “flutter”) on digital audio recordings in order to create an enhanced sense of motion and dynamics.","These effects may be familiar in the audio world because they result from imperfections in common analog playback systems, such as tape and vinyl While these effects may be overt, distracting, or detrimental to playback quality, they may be used subtly to create neutral and subliminal but perceivable motion and complexity in an audio recording.","Various embodiments of the presently disclosed subject matter may apply time-varying, semi-periodic frequency modulation of less than ±1 cent (where 1 cent represents the 1/100 of the difference between each semitone within an octave) and amplitude modulation of less than ±1 dB, at oscillation rates below about 5 Hz.","As with other modifications, the exact amount and rate of modulation may be driven by the analysis of input signal and may vary in response to the low-passed energy envelope of the signal, the presence of discrete, identified transients, momentary spectral complexity, or any other suitable property.","Automatic Level-Dependent Pitch Correction of Digital Audio A pitch correction signal processing technique modifies digital audio recordings to correct for level-dependent shifts in the perceived pitch of audio content.","These corrections compensate for the effects of sound level on perceived pitch, corrections that may be impractical to apply during performance or recording.","These corrections may improve the experience of listening to digital audio recordings by adjusting the perceived pitch of an audio signal dynamically.","The dynamic adjustment may be dependent upon the momentary loudness of the audio signal (e.g., audio signal intensity, audio signal power, audio signal level, audio signal volume).","The concept of auditory or musical pitch may be a perceptual one: while the pitch of a sound tends to be strongly related to mathematical properties of the associated acoustical wave such as its periodicity or frequency content, the relationship between such numerical properties and the perception of pitch may be more complex.","Significant research into this relationship was performed in the 1930's at various academic institutions and at Bell Labs, and this research revealed a strong interaction between the level at which a sound may be heard and its perceived pitch, meaning that the same sound heard at different levels or volumes may be perceived as having different pitches, even when no other mathematical properties of the sound signal (such as periodicity or frequency content) have changed.","At that time, studies were performed that further elucidated this relationship between sound level and pitch.","It was demonstrated that the amount of shift in perceived pitch for a given change in sound level may be dependent upon a complex interaction of signal characteristics, including the frequency content and absolute level of a sound.","One trend characterizing this relationship may be that for a simple tone (e.g., single frequency sinusoid), as level increases, the perceived pitch of that tone decreases for frequencies below about 2000 Hz and increases for frequencies above about 2000 Hz.","A general characterization of the relationship between the level, frequency content, and perceived pitch of complex sounds (sounds with multiple frequency components) has not been fully characterized for all complex sounds.","However, it was found that the shifts in perceived pitch that occur for complex sounds at varying levels may be predicted by a weighted mean of the shifts that would occur for each sinusoidal component of the sound if they were heard individually.","This finding suggests that, because many sounds produced by musical sources contain frequency content both above and below the zero-shift frequency of about 2000 Hz, most musical audio material may demonstrate small shifts in perceived pitch with changes in level relative to the shifts demonstrated by simple tones.","This phenomenon, that perceived pitch may be dependent upon sound level, poses a subtle problem for musicians and recording engineers.","Generally, musicians optimize the tuning of their instruments and their playing techniques to compensate for this effect when performing live together in a group.","Such adjustments may be subconscious or habitual rather than overt and deliberate, with professional musicians constantly making minute adjustments based on instinctual knowledge of their instruments and the feedback provided by their perception of pitch; however, it may be common in modern recording workflows for musicians to record their contributions to a song in isolation so that the individual sounds may later be layered or mixed together to form a final recording by a mix engineer, as this affords much more flexibility for adjusting the individual recordings and applying post-processing to individual sounds.","In this case, performing musicians cannot make the same adjustments to ensure that all parts of the resulting sound mixture may be perceived to have their desired pitches.","Additionally, many instruments do not provide musicians with the capability of making such subtle adjustments to the perceived pitch of the sound they produce, meaning that regardless of the recording situation there may be room for improvement through post-processing of recordings to make these adjustments.","Finally, when numerical tools such as frequency content analysis may be relied upon to tune instruments or later adjust the tuning of recorded sounds, this may not compensate for the phenomenon of perceived pitch may not be solely determined by frequency content may be usually neglected.","This may result in sounds that may be in need of further dynamic pitch adjustment to achieve or maintain desired musical pitches.","Because the perceived pitch of musical sound plays a large role in its emotional impact and perceived quality, even minor pitch adjustments may have a noticeable impact on the listening experience.","Research into psychoacoustics has demonstrated that the perceived pitch of a sound may be effected by the level at which that sound may be heard, meaning that minor adjustments to produced sounds may be required to sustain a particular pitch across differing sound levels.","Because modern recording techniques make it difficult or impossible for musicians to make these adjustments during performance and because such adjustments may not be possible, using digital signal processing techniques to apply dynamic, level-dependent adjustments to the pitch of recorded digital audio, when appropriate, may greatly enhance the listening experience.","A method for processing digital audio signals in order to correct for level-dependent shifts in the perceived pitch of audio content may be disclosed.","The method consists of analyzing a digital audio recording and creating small, dynamic shifts in perceived pitch as required to compensate for the pitch distortion caused by relative changes in momentary sound level.","This method may be suitable for processing of any type of digital sound recording, including individual sound recordings and complex sound mixtures.","This method may compensate for modern recording techniques that make it difficult or impossible for musicians to make such adjustments correctly in produced pitched during recorded performances and to improve the perceived pitch of recorded digital audio across changes in relative level wherever possible.","By correcting these small pitch distortions, the perceived quality of digital audio recordings may be improved without altering their creative content.","FIG.","10 illustrates a series single-channel analysis subsystem 1000, according to various embodiments of the present subject matter.","FIG.","10 demonstrates one

controlled or adjusted by higher-level parameters to select a particular relationship from a collection of options: for example, a high-level analysis of the input signals may determine the type of audio content that may be currently being processed (a general, individual instrument or some identified particular instrument, a complex sound mixture of multiple instruments, a sound mixture identified to belong within a particular genre of music, etc.)","and use this determination to choose a particular relationship between analysis output and modification from a collection of relationships that may be each most appropriate for a certain type of content.","Such high-level control and any lower level parameters of the relationship between analysis and modification may be exposed to an end-user through some type of interface for manual adjustment, or may be performed automatically.","Once an analysis configuration and relationship between analysis results and signal modifications has been determined, time-varying modifications may be made to the perceived pitch of the input signals.","These pitch shifts may be small, such as in the range of a shift in frequency of 0.015 to 1.15 percent (e.g., 0.25 to 20 cents, where 100 cents represents the difference between each semitone within an octave).","These small pitch shifts may be in accordance with the small perceptual shifts in pitch that occur for complex musical sounds with relative changes in level, and different amounts of pitch or frequency shift may be applied to separate spectral bands of the input signal.","In one embodiment of the presently disclosed subject matter, positive pitch-shift may be applied to signal content at frequencies above about 2000 Hz as signal levels fall below a nominal reference level in order to compensate for the decrease in perceived pitch that occurs for sinusoidal components in this frequency range as level decreases.","In another embodiment of the subject matter, the input signal may be split into numerous frequency bands and varying amount of pitch or frequency shift may be applied to each band according to analysis results in order to compensate for the changes in perceived pitch associated with the frequency content of each band during changes in relative sound level.","Several algorithms for applying pitch-shift or frequency-shift may be known to those skilled in the art of audio signal processing.","Any one or multiple of these algorithms may be applied to the input signals or portions of the input signals (isolated frequency bands, for example) to achieve the desired changes in perceived pitch, as determined by signal analysis.","If multiple algorithms were implemented and made available to the operator, the operator may determine which algorithm may be best suited to a particular bit of audio signal.","Alternatively, analysis of that audio signal may be used to determine automatically which algorithm may be best suited to each portion of audio signal.","Multiplexed Convolution A multiplexed convolution signal processing architecture applies multiple distinct types of processing to an input signal simultaneously in an adaptive, signal-aware way through the calculation of one or more time-varying convolutions.","The convolution kernels may be associated with points in a multidimensional behavior space, where coordinates correspond to parameters of the distinct processes being implemented.","The values of these parameters change over time in response to input signal properties, adaptively changing the convolution kernels and thus the results of processing.","In the present case, such processing may be achieved through the calculation of generalized convolution operations between an input signal and a time-varying convolution kernel, where the content of the kernel varies in response to properties of the input signal.","The mathematical operation of convolution between two functions, (f*g)(t)≡∫−∞∞f(τ)g(t−τ)dτ, (8) may be fundamental to linear systems analysis and may be well known in a variety of fields, including the field of signal processing.","The output of any linear time-invariant (LTI) system may be defined for arbitrary input signals as the result of convolution between those input signals and a function known as the system's impulse response.","This input-output relationship provides an extremely concise and powerful way of mathematically characterizing a broad class of systems that may be commonly encountered in the physical world and that may be frequently used in an endless variety of applications.","In more common notation, this relationship can be expressed as (y)(t)≡∫−∞∞h(τ)x(t−τ)dτ, (9) for an input signal x(t), time-invariant system impulse response h(t), and corresponding output signal y(t).","The convolution defined in equation (8) and equation (9) may be a linear operation and thus cannot be used directly to implement nonlinear processing.","However, it may be possible to formulate the input-output relationship of a system whose behavior varies over time in response to characteristics of the input signal as a form of generalized convolution that may achieve nonlinear system behavior.","The main difference between such an alternative formulation of convolution and the standard definition presented in equation (8) may be that the two functions, f and g, do not remain independent of one another.","In terms of the more standard linear system notation presented in equation (9), the system response h(t) becomes dependent upon not just time t, but the input signal x(t) itself.","While this introduced dependence may make the analysis of overall system behavior much more complicated, it also creates the possibility for more complex system behavior such as nonlinear processing.","For example, we may use the definition (y)(t)≡∫−∞∞H{SHIFT−t{X}}(τ)x(t−τ)dτ, (10) where H{⋅} and SHIFTt{⋅} define operators whose domains may be the set X of all functions x with the real numbers as both their domain and range, X={x|x: R→R}, and whose ranges may be the same set of functions, written as H: X→X and SHIFTt: X→X.","In this case, the operator H{⋅} defines the relationship between the input signal x(t) and the system response h(t) in a general way, and the operator SHIFTt{⋅}, defined as SHIFTt{X(α)}≡X(α−t), (11) serves the purpose of making the input-output relationship of the overall system time-invariant, meaning that the relationship between the input signal x(t) and the system response h(t) defined by H{⋅} takes into account only relative differences in time between input and output and has no sense of overall time.","The generalized convolution operation defined in equation (10) characterizes the dynamic system through a particular kind of time-varying system function known as an input delay-spread function, albeit one that has the unusual property of being dependent upon the input signal itself.","A similar definition with slightly different behavior may be written as (y)(t)≡∫−∞∞H{SHIFT−(t-τ){X}}(τ)x(t−τ)dτ, (12) where the dynamic system may be instead characterized through a time-varying system function known as an output delay-spread function.","The difference between these types of time-varying system functions may be in whether the particular system function at time t, ht(τ), may be constant for a time t associated with the output signal being calculated or with the input signal being used to calculate the output.","Otherwise, both definitions capture the same dependence of system behavior upon the input signal x(t) and provide essentially the same definition of a generalized convolution operation.","The system definitions given in equations (10) and (12) make it possible to achieve both linear and nonlinear system behavior with the same general system architecture, and thus provide a unifying framework through which multiple different processes may be applied to a signal simultaneously; however, this type of general, dynamic system description has not been used to unify multiple simultaneous processes in this way previously.","Because multiple distinct processes performed on an input signal can interact in complex ways when some of the processes may be nonlinear, and because various system architectures may exhibit different behavior when made to be time-varying, it may be desirable to devise such a unified system so that all individual processes may be controlled simultaneously in a way that takes their interactions into account and allows for the desired overall processing to be consistently achieved when making changes to parameters of one or more of the individual processes.","A method for processing digital signals in order to simultaneously implement multiple linear and/or nonlinear processes in a general way that allows for control of interactions between each stage of processing and adaptive, signal-aware system behavior is disclosed.","The method consists of defining a range of system behaviors, each designed to achieve the best overall processing results associated with a set of parameter values describing the individual implemented processes, and then analyzing input signal properties to determine the desired values for these parameters at each moment in time.","The connection between analysis results and system behavior may be described by a multidimensional system-behavior space in which coordinates correspond to parameters of the distinct processes being implemented: Each designed system behavior may be associated with a point in this space, and analysis of input signal properties determines where in the space the system should currently be operating.","All possible system behaviors may be described in a consistent and general way as one or more generalized convolutions whose outputs may be combined to generate the system output, allowing for smooth transitions and interpolations between specified system behaviors, control of interactions between the various implemented processes by way of total system behavior specification, and consistent time-varying behavior across all implemented processes.","A unified system may simultaneously implement multiple linear and/or nonlinear processes in a manner that may be time-varying responsive to various characteristics of the input signal.","Because processes implemented through different architectures may exhibit inherently different behavior when made to be time-varying and because the interactions between multiple stages of processing may be complex when nonlinear processes may be performed, such a unified system may be intended to allow for more consistent and detailed control of overall system behavior when multiple processes may be to be applied to an input signal simultaneously in a time-varying, signal-aware manner.","A system that processes digital signals in a way that allows for the simultaneous application of multiple linear and/or nonlinear processes in a general, well-controlled, and signal-aware way is disclosed.","The system takes as its input one or more digital signals.","These signals may each be a series of digitally stored values representing the instantaneous amplitude of a band-limited waveform that has been sampled at regularly spaced moments in time.","In many embodiments of the presently disclosed subject matter, these digital signals may represent digital audio signals, corresponding to the sampled amplitude of an audio waveform over time.","The presently disclosed system both analyzes and modifies these input signals, with the results of input signal analysis determining the modifications to be performed at each point in time.","This relationship between analyzed signal properties and resulting modifications may be established by indexing into a multidimensional system-behavior space with coordinates that correspond to parameters of the various individual processes being implemented.","The results of input signal analysis at any given moment determine the desired parameter values for all of the individual processes, and thus a particular point in behavior space.","The pre-determined (designed) system behavior associated with that particular point in behavior space may be then used to calculate the system output.","As input signal properties vary over time, so do the associated point in behavior space, and thus the overall system behavior.","FIG.","14 demonstrates the multiplexed convolution system architecture 1400 according to various embodiments of the present subject matter.","FIG.","14 consists of a signal-analysis

each parameter controls the general degree to which each process may be applied to the input signal.","Each process would thus operate at one of 8 levels.","A system behavior may then be specified for each point in this space, taking potential interactions between the individual processes into account and ensuring that the behavior varies smoothly everywhere.","FIG.","18 presents an illustrative

exemplary digital computer embodiment of the system-behavior determination operation based on look-up tables.","In this embodiment of the present subject matter, the point in behavior space corresponding to the current determined individual process parameter values takes on integer values 1910.The integer values 1910 may each correspond with one or more indices within a multidimensional array of memory addresses 1920 stored in a computer.","At each moment in time, the current parameter value vector 1910 may be used to index into this array 1920, and the memory address at the specified index may be followed to a block of memory 1930 that specifies the system behavior for that particular set of parameter values.","The first entry in this block of memory 1930 may be a code that specifies a combination topology for the outputs of the LTI process 1940 or for the outputs of the generalized convolutions 1950.The remaining entries may contain one memory address per individual process.","For example, the embodiment in FIG.","19 contains P such processes.","The first value pointed to by each of these individual process addresses may be a Boolean flag indicating whether the process may be linear time-invariant (LTI).","If Boolean flag indicates that the process is LTI, the entries following the flag specify the impulse response for that LTI system.","If the process may be nonlinear, the flag may be set to false, and the subsequent single entry may be a function pointer used to evaluate the generalized convolution kernel for that nonlinear process.","This effectively implements the overall system again recursively, as may be discussed in detail later.","This look-up process repeats until all individual processes terminate at a set of LTI system impulse responses, which may be then combined and evaluated according to the indicated output topologies in order to form the system output.","While FIG.","19 shows a simple example, more complex embodiments may require the storing and interpreting of additional metadata for each process and response.","In order to enable the simultaneous implementation of several types of processing in this continuously time-varying and general way, all possible system behaviors may be discussed using a consistent, general architecture: at all times, the system performs one or more generalized convolutions with input signals and combines the results of these convolutions according to a topology consisting of series and parallel connections to form the output signal.","Thus, each point in behavior space dictates a set of generalized convolution kernels and a topology for combining the convolution outputs.","These convolution kernels and combination topologies may be designed to best achieve the overall processing results specified by the associated set of individual process parameters, taking possible interactions between processes into account, and may be designed to vary in such a way across nearby points in behavior space that overall system behavior may be guaranteed to vary smoothly while changing in response to properties of the input signal.","By describing the overall system behavior in this way, the system may be able to manage interactions between multiple individual processes.","It may be often easiest to describe a desired overall processing system as a signal-flow graph consisting of several discrete, well-understood parts that each serve a particular function.","However, complicated interactions between the effects of these individual processes in the presence of nonlinearity generally dictate that when the parameters of one process may be changed, the parameters of other processes must also be changed in order to compensate and keep their contribution to the overall system equivalent.","These compensating changes may be difficult to derive for many multi-process systems when using common parameterizations and implementation architectures for each discrete process, which may vary significantly depending on the type of process being implemented.","Further complication arises when imposing time-varying behavior on a multi-process system in which the various processes may be implemented using different architectures, as each individual architecture may have unique restrictions on its ability to change over time and may produce varying artifacts or undesirable consequences when changing configuration or parameter values.","In order to allow better time-varying control of multiple simultaneous processes, an alternative approach may be used to control overall system behavior through the adjustment of individual process parameters.","In particular, the desired overall system behavior for each combination of individual process parameters may be specified through the use of one or more generalized convolutions that may or may not reflect various discrete processing components, and that can be designed without the restrictions of discrete component parameterizations in order to better maintain overall desired system characteristics.","The system response kernels for these convolutions can then be made to vary smoothly in response to changes in individual process parameters, allowing the system behavior to change smoothly over time and in a way that preserves the desired overall processing across all possible behavior trajectories without the need for directly analyzing the complex interactions between individual processes.","Furthermore, by implementing all processing as generalized convolutions, overall system implementation may be simplified: various processes may be achieved using varying generalized convolution kernels rather than varying architectures and techniques, and consistent time-varying behavior can be achieved across all processes in the system.","Additional analysis and modifications are discussed below in more detail.","Multiplexed Convolution: Adaptive, Signal-Aware Control of System Behavior The first step in determining the system response at any particular moment in time may be to determine where, in behavior space, the system should be operating based on the current input signal content.","If we denote the location of the system in behavior space at time sample n as θ[n], we can express this procedure as evaluating part of the operator H{⋅} presented in equation (10) as θ[n]=Hθ{SHIFT−n{X}}, (13) where H{⋅}=Hh{Hθ{SHIFT−n{X}}} (14) gives a decomposition of the relationship between input signals x and system response h, denoted as H{⋅}, into two separate steps: one operation which analyzes signal properties and maps to a point in system behavior space, Hθ{⋅}, and another operation which maps from that point in system behavior space to a description of system behavior in terms of generalized convolution kernels and system topology, Hh{⋅}.","Here, our behavior space, which we may refer to as Θ, may be a p-dimensional space, where p may be the number of parameters characterizing the operation of the system, and we have that θ[n]ϵΘ for all n. In general, Θ need not be a continuous space; in some cases we may only allow θ[n] to take on values from a specific, discrete collection of settings or values.","Note that FIG.","18 shows signal analysis and Hθ{⋅} as separate blocks.","This may be caused by embodiments of the presently disclosed subject matter in which the types of signal analyses performed and the way that their results map into behavior space may be separable, such as depicted in FIG.","18.However, it may be more useful to describe Hθ{⋅} as representing all processing from input signals to θ[n].","In general, any available data may be analyzed and used to determine the value of θ[n] at each point in time, including additional metadata supplied to the presently disclosed system separately from the input signals themselves.","Furthermore, the relationship between analysis results and θ[n], represented by Hθ{⋅}, may itself be controlled or adjusted by higher-level parameters resulting from signal analysis or external controls.","Depending on the particular implementation, this may be thought of as selecting one Hθ{⋅} from a collection of options or as warping the function mapping between signal analysis results and points in behavior space by some additional operation W: Θ→Θ, as W{Hθ{⋅}}.","An example of a high-level parameter that might be used in this manner would be a specification of the general type of digital signal being processed, either determined through automatic classification or through manual specification by an operator prior to processing.","This capability of altering Hθ{⋅} itself may be most applicable to embodiments of the presently disclosed subject matter that may be used for processing numerous types of signals, where the types of signals are fundamentally different in structure.","In other embodiments, this capability of altering Hθ{⋅} itself may be excluded when not needed.","In embodiments of the presently disclosed subject matter where the disclosed system is applied to audio signals, input signal properties such as spectral content, energy or perceptual loudness, the presence of transient changes in intensity or energy.","Additionally, signal property relationships between multiple input signals designed to be reproduced together acoustically using a multichannel speaker array may play a large role in determining θ[n] at any moment in time.","An exemplary signal-analysis subsystem that considers these properties may be depicted in FIG.","18.In these embodiments, higher-level parameters such as the type of audio content contained in the signal (a specific instrument, speech, a musical recording adhering to a particular genre, etc.)","may be determined automatically from analysis of the audio signals or specified manually by an operator through some type of user interface in order to determine the appropriate behavior space mapping Hθ{⋅} for the current class of signal.","In one embodiment of the present subject matter, the entire durations of previously recorded digital signals may be analyzed and considered when determining the varying modifications to be made across the duration of the signals.","In another embodiment of the presently disclosed subject matter, modifications may be made to digital signals in real-time that may be, as they may be being created, recorded, or presented as a stream of data.","In this embodiment, analysis of the digital signals' previous and current content may be used in determining the modifications to be made to the signals at the present moment, or an overall delay may be imposed on the throughput of the system such that some amount of future data may be considered when determining the modifications to be performed.","Furthermore, analyses of multiple signals that may be somehow related may inform the processing of those signals in any relevant way.","For example, the same modifications may be applied to multiple digital signals as determined by analyses performed on each signal in the collection, multiple signals may be analyzed and modified independently, or an analysis of an entire collection of signals may inform the varying modifications to be made to each signal in the collection.","Each of these exemplary configurations as well as other analysis and control configurations may be relevant and useful in various contexts.","These analysis configurations are presented as illustrations of the wide range of possible configurations, and additional analysis configurations may be used.","Practically, the connection between analyzed signal properties and associated points in behavior space, Hθ{⋅}, may be established in any suitable form that may be accessible by the system.","In one embodiment of the presently disclosed subject matter, this relationship may be stored as a collection of pre-determined digital look-up tables that relate results of signal analysis to points in behavior space.","Such look-up tables may be indexed by raw, numerical analysis results, by higher-level analysis results based on a synthesis of several signal properties including logical, rule-based processing of basic analysis results, or by some other result of signal analysis.","They may map to a discrete-valued behavior space, Θ, or have tabulated values that may be interpolated in order to map into a continuous Θ.","In another embodiment of the subject matter, this relationship may be established by a set of parameterized equations that relate numerical results of signal analysis to coordinates in a continuous Θ.","It should be noted that the parameterizations of individual processes reflected in the coordinates of the behavior space Θ may correspond to a wide range of characteristics varying from low-level mathematical parameter values to high-level parameters describing the overall effects of processing or the degree of processing applied.","The connection between points in behavior space and implemented system behavior, Hh{⋅}, may be chosen during design of a specific embodiment and may be entirely general; the relationship may be any that can be captured by the specification of system behavior associated with each point in behavior space, as may be discussed in more detail in the following subsection.","Multiplexed Convolution: Description and Implementation of System Behavior Various system behaviors may be achieved through the calculation of one or more generalized convolutions, and by combining the convolution outputs according to a specified system output topology.","For applying these behaviors to recorded digital signals, modifications of equations (10) and (12) may be used to calculate the discrete-time generalized convolution outputs as y [ n ] = ∑ m = - ∞ ∞ H { SHIFT - n { x } } [ m ] × [ n - m ] ( 15 ) in the input delay-spread function case and y [ n ] = ∑ m = - ∞ ∞ H { SHIFT - ( n - m ) { x } } [ m ] × [ n - m ] ( 16 ) in the output delay-spread function case, either of which may be used.","Each point in system-behavior space may be associated with a set of generalized convolution kernels and an associated output combination topology designed to achieve the specified underlying individual process parameters.","With H{⋅} subdivided as in equation (14), this may be represented by the operator Hh{⋅}, which provides a mapping from points in behavior space Θ to the overall system response.","Ultimately, this response may be characterized by a collection of traditional convolution kernels, one for each of P individual processes, hi[n], i=1, .",".",".",", P, and a specified topology for evaluating and combining the outputs of these standard convolutions.","Convolution with each kernel may be then evaluated using the standard discrete-time convolution operation, y i [ n ] = ∑ m = - ∞ ∞ h i [ m ] × [ n - m ] , ( 17 ) where hi[m] may be zero for all m<0 (as in causal systems), or at least for all m BACKGROUND Systems that provide audio playback, such as portable flash

Nonlinear Properties of Sound Propagation and Mixing in Air The experience of listening to digital audio recordings is improved by making subtle modifications to the recorded audio signals that simulate the linear and nonlinear effects of propagation and mixing of sound in air.\",\n \"The mixing in a nonlinear medium of multiple or complex sound waves comprised of multiple frequencies is known as heterodyning.\",\n \"Heterodyning may occur at various locations in the air, including at a speaker or at the user's tympanic membrane.\",\n \"Because the speed of sound in air is itself dependent upon the particle velocity or pressure of the air at any given moment in time and position in space, air may not be a purely linear propagation medium.\",\n \"For example, the compression peaks of an acoustic waveform may travel faster than rarefaction troughs, distorting the waveform and transferring energy into higher harmonics of the original signal.\",\n \"When multiple or complex sound waves comprised of multiple frequencies propagate in such a nonlinear medium, the sound waves transfer energy into sound at new frequencies (e.g., intermodulation products) given by the sums and differences of the original signal frequencies.\",\n \"While these nonlinear effects of air are generally subtle at auditory frequencies and typical sound pressure levels (SPLs) (e.g., loudness levels), second-order nonlinear effects may generate content at levels as high as only 30 decibels below the primary sound pressure and are often perceptible during live music performances.\",\n \"These second-order intermodulation products have amplitudes proportional to a derivative of the products, which may result in intermodulation products or other propagation effects that increase with an increase in frequency.\",\n \"Nonlinear propagation effects of audible frequencies may also interact with lower frequencies in an intermodulation scheme.\",\n \"Thus, the nonlinear effects of air may play an appreciable role in how the brain processes and perceives sound.\",\n \"The mixing signal processing technique may improve the ability of a system to reproduce the effects of a live performance using a digital audio recording.\",\n \"While some music is experienced through live performance, most music is experienced through listening to stored analog or digital audio signals.\",\n \"Digital audio signals are converted to analog signals using digital-to-analog converters, and the original or converted analog audio signals are reproduced acoustically by headphones, open-air loudspeakers, or other means.\",\n \"The reproduced signals may contain unnatural content, as the reproduced signals represent recorded or synthesized waveforms that have not propagated through air or otherwise mixed in ways that are naturally encountered with live sound.\",\n \"For example, many genres of music may use recording techniques known as “close-mic'ing” and “overdubbing,” often in combination.\",\n \"These techniques may include minimal amounts of propagation and mixing in air, and may result in sterile recordings of sounds.\",\n \"In close-mic'ing, microphones are placed in close proximity to the sound source.\",\n \"Close-mic'ing can be used to capture direct sounds, while simultaneously reducing energy captured from other sound sources and reducing acoustic reflections occurring in the room where the recording is taking place.\",\n \"In contrast to listening to live music at a range from 1 meter to tens of meters, close-mic'ing sound-source-to-microphone distances may range from about 10 centimeters for recording vocalists to 5 centimeters for recording amplified guitar or acoustic drums.\",\n \"In each case, the recorded sound waveform may experience extremely little propagation in air, and therefore may not include effects generated by propagation associated with a similar sound source heard from a more natural listening distance.\",\n \"When multiple musicians are recorded performing in a space at the same time, close-mic'ing may enable a mix engineer to control their relative volumes individually or apply special processing to a subset of performers.\",\n \"While this isolation of sounds is useful during mixing, natural effects of nonlinear propagation and mixing in air evolve gradually over distance and may require up to tens of meters of propagation to fully develop, and close-mic'd recordings may fail to capture these natural effects of nonlinear propagation and mixing in air.\",\n \"The recording technique of overdubbing may isolate individual sounds more than close-mic'ing, and may also fail to capture natural effects of nonlinear propagation and mixing in air.\",\n \"In overdubbing, additional sounds are recorded and synchronized with previously recorded sounds in order to build a recording of a full ensemble or song gradually through summation of multiple individual recordings.\",\n \"Because modern digital audio workstations make it easy to layer a large number of individual recordings, each instrument or performance that contributes to a song is recorded individually.\",\n \"For example, performers may play an instrument while listening to previously recorded parts of the song or a timing cue (e.g., metronome), and may record each instrument or vocal component individually until every song component has been recorded.\",\n \"These individually recorded song components may also be close-mic'd to avoid room reflections and capture an isolated audio recording (e.g., dry sound).\",\n \"Through heavy use of these techniques, many modern recordings include numerous individual close-mic'd waveforms that are mathematically added together by a computer and have not propagated and mixed in air as they typically would have in a natural live performance.\",\n \"In particular, digital audio waveforms that have been generated electronically or synthesized digitally may not have experienced any propagation or mixing in air.\",\n \"These digital audio waveforms are an extreme example of modern recording practices, as they are completely isolated from the other sounds contributing to a song or sound mixture, and may include little or no additional content or imprint from the space in which they were recorded.\",\n \"Furthermore, when these sounds are later reproduced acoustically, it is often in a setting that does not allow for the propagation distance or source SPL (sound pressure level) needed for the generated sound to experience the amount of nonlinear propagation normally incurred during live performances or large-scale concerts.\",\n \"This is true for many home and car playback systems and listening environments, and is particularly relevant to headphones and earphones.\",\n \"For example, headphone propagation distance of reproduced sound can be less than 6 millimeters, which may allow a recorded sound to propagate in air for 5 to 10 centimeters from source to microphone and then earphone to the tympanic membrane.\",\n \"Additionally, headphones may use a lower source SPL, as little spreading or propagation loss occurs.\",\n \"Because modern recording techniques and common listening settings reduce or eliminate nonlinear propagation effects often present and audible during live performances, it is beneficial to recreate these effects through digital signal processing so a more natural sound is provided by digital recordings in typical listening environments.\",\n \"The acoustical sidebands created by sound heterodyning in air give an added spectral and harmonic richness to sound that is commonly absent from the modern listening experience and would be beneficial to reproduce digitally.\",\n \"Additionally, it is desirable to impose some of the frequency-dependent attenuation that accompanies natural propagation of sound in air to restore a more natural tonal balance to close-mic'd recordings, and to improve simulation of nonlinear interactions between or among sound components as they propagate.\",\n \"Beyond compensating for modern recording techniques and playback settings, the use of digital signal processing to simulate nonlinear propagation and mixing of sound in air may enhance the experience of listening to digital audio.\",\n \"The nonlinearity of air is most pronounced when high sound pressure levels are present, and listeners often find that higher listening volumes provide a more compelling and immersive listening experience.\",\n \"Digitally introducing the nonlinear effects that would have occurred at high playback volumes may make playback at lower volumes more exciting and enjoyable by simulating part of the experience of listening at high SPLs.\",\n \"FIG.\",\n \"2 shows a system 200 for simulating linear and nonlinear effects of propagation and mixing of sound in air according to various embodiments of the present subject matter.\",\n \"System 200 may operate on one or more input signals in order to generate intermodulation products that would be generated naturally during acoustic propagation of one or more signals at a given peak sound pressure level and then mixing these products with the original input signal(s).\",\n \"Additional linear filtering is imposed by the system before, during, or after this process in order to simulate the natural frequency-dependent attenuation of sound as it propagates through air.\",\n \"System 200 may improve the listening experience by compensating for modern digital recording techniques and listening settings that reduce or eliminate the natural attenuation and nonlinear effects of sound propagation through air and by simulating high SPL playback of audio at lower volumes by introducing the nonlinear effects of sound propagation at high SPLs into the recorded waveform itself.\",\n \"System 200 modifies source material in a transparent and potentially subtle way while not altering the creative content of processed recordings, making it suitable for application to all varieties of musical or audio content recorded and stored in digital form.\",\n \"System 200 takes as its input one or more input signals (Xi) 210 that represent the amplitude of one or more audio waveforms over time.\",\n \"In various embodiments, these input signals 210 are a series of digitally stored values representing the instantaneous amplitude of a band-limited waveform that has been sampled at regularly spaced moments in time.\",\n \"Each input signal (Xi) 210 may have a corresponding primary sound pressure (P1) 220.The primary sound pressure 220 is provided to a processor 230 for calculation of a secondary soundfield.\",\n \"Processor 230 is a general purpose processor, a dedicated digital signal processing (DSP) integrated circuit (IC), or another type of processor suitable for the calculation of the secondary soundfield.\",\n \"The output of processor 230 includes a secondary sound pressure (P2) 240, where the secondary signal 240 may simulate effects that would have occurred at high playback volumes to simulate a live mixing of the various sounds.\",\n \"Primary and secondary sound pressures 220 and 240 are combined through superposition within an adder 250.Adder 250 includes a digital adder circuit or a summing amplifier and may include additional summation or timing components.\",\n \"For example, processor 230 may introduce a delay in the secondary signal 240 relative to the primary signal 220, and adder 250 may include a fixed time delay or a synchronization module to detect the delay of the secondary signal 240.Adder 250 may combine primary and secondary sound pressures 220 and 240 to provide a sound pressure output signal (Yi) 260, where output signal 260 may simulate what the listener would hear at a live event.\",\n \"System 200 may modify the input signal(s) in a manner dependent upon one or more controlling parameters.\",\n \"Generally, these parameters define physical attributes of the simulated sound propagation and mixing and thus directly influence the formulas used to calculate the intermodulation products generated by the nonlinearity of air.\",\n \"Alternatively, higher-level parameters are used to control the overall character or extent of the processing.\",\n \"In some embodiments of the subject matter, these parameters are determined automatically through an additional mathematical analysis of the input's auditory content and the application of a rule or decision system that links analyzed signal content parameters to control parameters.\",\n \"Because digital audio signals generally contain complex waveforms comprised of multiple frequency components and are applied during the mixing of multiple recorded sounds, the present subject matter in various embodiments uses quasi-linear solutions of Westervelt's general inhomogeneous wave equation to determine the relationship between input signals and generated intermodulation products.\",\n \"In one embodiment of the subject matter, the Westervelt equation for second-order mixing, ∇ 2 P 2 - 1 c 0 2 ∂ 2 P 2 ∂ t 2 = - ρ 0 ∂ q ∂ t , ( 1 ) is used to capture the second-order intermodulation products generated by the nonlinearity of air, as these are generally the most prominent of intermodulation products.\",\n \"In equation (1), secondary sound pressure (P2) 240 is the pressure variation associated with the intermodulation products generated by the nonlinearity of air, (ρ0) and (c0) represent the density and small-signal sound speed of air, respectively, and (q) is the virtual source density given by q = β ρ 0 2 c 0 4 ∂ ∂ t P 1 2 , ( 2 ) which is proportional to the time derivative of the square of the primary sound pressure (P1) 220.Here, β represents the second-order nonlinear coefficient of air, which may vary with the interaction angle of component sound fields if the primary sound pressure may be a mixture.\",\n \"The general solution to differential equation (2), which can be used by one embodiment of the presently disclosed subject matter, is P 2 = - ρ 0 4 π ∫ V ∂ q ∂ t e ik s r ′ r ′ dV , ( 3 ) where (ks) is the wavenumber corresponding to an intermodulation product, (V) is the interaction volume over which the primary sound pressure has sufficient amplitude to contribute to the generation of intermodulation products, and (r′) is the distance from each virtual source point in the interaction volume (V) to the location where the generated secondary field is observed.\",\n \"In this exemplary embodiment,

harmonics of all frequencies present in the input signals, each with amplitudes that may be proportional to the square of their frequencies.\",\n \"Whether using one, two, or more isotropic sources, sound pressure output signal (Yi) 260 may be formed by mixing the secondary sound field (P2) 240 with input primary sound pressure (P1) 220 to arrive at the total sound field that would be observed in air.\",\n \"The naturally occurring relative amplitudes of the primary and secondary sound fields 220 and 240 may be given by the solution to equation (1).\",\n \"The sound pressure output signal (Yi) 260 may be further controlled by additional parameters, either interactively by a user, automatically according to analysis of the input signals 210, or by other means.\",\n \"Linear filtering may be used to simulate frequency-dependent attenuation of sound as it propagates through air.\",\n \"Linear filtering may be applied to the input signals 210 before or after calculating output signal 260, depending on computational considerations and other design choices.\",\n \"Characteristics of such linear filtering may be selected to simulate or reduce attenuation properties of air.\",\n \"The present subject matter applies the Westervelt equation to audible frequencies to compensate directly for modern recording techniques or simulate accurately the effects of high SPL playback of digitally recorded audio to enhance the listening experience.\",\n \"Typical uses of the Westervelt equation deal with ultrasonic sound.\",\n \"Most applications, such as high-intensity focused ultrasound and industrial applications of ultrasound, such as cleaning and welding, may be very different from that of the presently disclosed subject matter.\",\n \"The Westervelt equation has been used in the field of parametric acoustic arrays, such as in the analysis and design of systems that generate beams of ultrasonic sound in order to produce directionally controllable content at audio frequencies through the nonlinear interactions of these ultrasonic beams in air.\",\n \"Because the nonlinear effects of air increase with frequency, these effects may be strongly present at ultrasonic frequencies, but may be subtle at audio frequencies.\",\n \"As a result, mathematical application of these nonlinearities to date has focused on ultrasonic applications, and not on digital audio waveforms with content only in the auditory band for enhancing listening during playback.\",\n \"Additional methods may be used to simulate intermodulation products generated by audio-band sound due to the nonlinearity of air.\",\n \"A reduced solution may include second-order effects and intentionally exclude higher-order intermodulation products.\",\n \"Because of the generally low amplitudes of higher-order intermodulation products generated at reasonable SPLs at audible frequencies, the second-order embodiment discussed above may be sufficient to achieve the desired results, however other embodiments are possible.\",\n \"In some cases, particularly when simulating very high source SPLs or when input waveforms have particular spectral properties, the calculation of higher-order intermodulation products may be desirable.\",\n \"Higher-order calculations may be included in an embodiment of the subject matter if deemed necessary by a user or through analysis of the input signal.\",\n \"Digital Signal Processing of Priming Signal for Reduction of Stress in the Auditory System A priming signal processing technique modifies digital audio recordings to reduce the stress experienced by a listener's auditory system.\",\n \"A priming signal may reduce the instantaneous stress experienced by the auditory system during sudden changes in signal energy.\",\n \"The priming signal may be generated such that pre-signal priming additions may not result in obvious differences in perceived sounds, thereby leveraging temporal auditory masking.\",\n \"A method for processing digital audio signals in order to decrease the stress experienced by the auditory system of a listener without overtly changing the creative or musical content of the signal may be disclosed.\",\n \"The method consists of an adaptive, time-varying system that responds to characteristics of input signal content according to a rule system, and that alters the signal either by mathematical convolution with one or more response templates or by the momentary addition of noise-like signals.\",\n \"Unlike existing audio processing techniques, this method may not be intended to generate obvious audible differences in the content of an audio signal, but rather to cause an appreciable difference in the comfort and enjoyment of the listener by conditioning the signal to interact more gently or naturally with the listener's auditory system.\",\n \"This method may be designed to compensate either directly or indirectly for the deleterious effects of unnaturally synthesized, mixed, or recorded digital audio signals as well as other potential shortcomings of digital audio formats and reproduction.\",\n \"Due to its ease of implementation, this method may be suitable for application to all varieties of musical or audio content recorded and stored in digital form.\",\n \"Synthetic generation of acoustic waveforms provides extensive creative opportunities.\",\n \"However, synthetic waveforms also present the listener with audio material that defies many properties of natural sound.\",\n \"Because these synthetic waveforms do not adhere to physical laws that the auditory system may be designed to understand, this defiance may cause stress on the human auditory system in processing and interpreting these signals.\",\n \"While the creative freedom afforded by these signals should not be diminished, it may be desirable to introduce processing that may compensate for differences between expected and experienced characteristics of sound.\",\n \"Such compensation may allow creation of a more enjoyable listening experience without significantly altering the creative content of the audio.\",\n \"Furthermore, it may be generally desirable to process audio signals in ways that reduce the stress experienced by a listener's auditory system, whether or not such stress reduction may be achieved by imitating the natural behavior of sound.\",\n \"There may be many known phenomena in the human auditory system that may be relevant to the present discussion.\",\n \"At a high level, humans may be able to derive much information about their surroundings from analyses of patterns of reflections or multiple arrivals of the same acoustic signal.\",\n \"For example, the auditory system may be able to use the filtering and delay imposed by the shape of the human head and ears (e.g., head-related transfer functions) to determine the direction from which a sound originated.\",\n \"Reflections of a sound arriving after the initial direct path may be used by the auditory system to understand characteristics of the space surrounding a listener such as whether or not it may be enclosed, how distant nearby walls or other solid or semi-solid surfaces (such as groves of trees) might be, and the types of materials present in the surroundings (hard and reflective or soft and absorbent).\",\n \"Such reflections can also be used to understand the location of a sound source relative to the listener: the pattern of reflections that arrives at a listener varies with changes in the relative locations of the listener and the source, creating auditory cues for distance and obscuration.\",\n \"All of this high-level auditory information may be derived instinctually, without conscious training or attention, and may be based on the auditory system's understanding of how sound naturally interacts with its environment.\",\n \"The majority of cues for this understanding may be contained in filtering and arrival patterns during the first 100 milliseconds or so after a direct signal, and our ability to make sense of these cues indicates a specialization of the human auditory system for processing naturally occurring audio signals.\",\n \"At a lower level, it may be known that a wide range of similar acoustic signals may be perceived to present the same sound.\",\n \"Although the human auditory system may be complex and not fully understood, this phenomenon has been studied extensively and may be known as auditory masking: the process by which the presence of one sound can render another sound imperceptible.\",\n \"This effect may be a result of both the mechanics of the human peripheral auditory system, which transduces acoustic energy into electrical neural activity, and higher level processing performed in the central auditory system.\",\n \"Acoustic energy may be transduced into neural activity in the cochlea by inner hair cells, which release neurotransmitters in response to mechanical deflection and incite action potentials (e.g., electrical spikes) in the primary auditory neurons.\",\n \"Various encoding schemes, such as first-spike latency, rate-based coding, and detailed temporal codes may be then employed by the auditory system to transmit and analyze these initial excitations.\",\n \"Stated simply, if a dominant sound may be already exciting a particular group of neurons, it may prevent a weaker sound that would excite the same neurons from being perceived.\",\n \"This may be known as simultaneous masking.\",\n \"Additionally, because much of the processing performed by the central auditory system involves integration of neural spike signals over some duration of time and because the human auditory system may temporarily decrease its sensitivity to sound in reaction to loud stimuli, masking can extend over a duration of time: a loud sound may render quieter sounds immediately preceding it or immediately following it imperceptible, with an influence that extends longer afterward than before (approximately 20 milliseconds before and 100 milliseconds after a loud sound, with influence decaying exponentially away from the time of the sound).\",\n \"This may be known as temporal masking.\",\n \"Finally, because each point along the length of the cochlea may be tuned to a specific frequency, sounds that may be similar in frequency may primarily excite the same groups of neurons, and may be more likely to mask one another through either type of masking.\",\n \"This phenomenon of auditory masking means that it may be possible to make significant modifications to an audio signal which do in fact present the human auditory system with a different stimulus but which do not yield obvious differences in the content of the signal.\",\n \"This may be the principle that underlies lossy compression schemes for digital audio such as the ubiquitous .mp3 standard, which may be designed to throw away a large portion of the information contained in an audio signal without changing the way that it sounds to a listener.\",\n \"Here, this principle may be exploited to apply processing which has an appreciable effect on the listening experience without obviously altering the auditory system's interpretation of the processed data.\",\n \"The present system analyzes and modifies this input signal; the exact modification performed on the signal at any given time may be dependent upon the current analysis output, and may vary with momentary changes in characteristics of the input signal.\",\n \"In various embodiments, two main methods of modifying the input signal may be employed.\",\n \"One of these methods may be to modify the input signal by performing the mathematical operation of convolution using the input signal and one or more convolution template signals.\",\n \"The other method may be to introduce additional, momentary noise-like components into the output signal.\",\n \"Digital Signal Processing of Priming Signal: Methods of Modifying the Input Signal FIG.\",\n \"5 illustrates an embodiment of a signal-modification processing subsystem 500 for introduction of a priming signal, according to various embodiments of the present subject

A system may select one of symmetric or asymmetric example waveforms 810, 820, 830, 840, 850, and 860, and therefore select the delay and position of silence, in order to reduce the perception of the artificial duration of silence.\",\n \"In natural acoustic environments, the sound heard by a listener may be always the combination of an initial direct-path arrival followed by subsequent early reflections.\",\n \"In nearly all cases, this leaves duration of silence (for example on the order of milliseconds) in the room response between the initial first arrival and the first-arriving reflection.\",\n \"Although the details of this first-arriving reflection and other soon-arriving early reflections may vary greatly with the positions of a sound source and listener or the acoustic space in which they reside, these changes in response generally do not alter the observed character of a sound in an obvious way.\",\n \"For example, a particular sound source such as an instrument or a particular person's voice may be recognizable in a wide variety of spaces from a small, enclosed room to a huge cathedral; the sound identified as being produced by the source does not change significantly in character, despite the fact that the sound associated with the space it may be in changes drastically.\",\n \"This may not be to say that such responses cannot contribute to the perceived character of a sound, but to demonstrate that many convolution templates with some duration of silence trailing the zero-delay component may be expected to yield subtle effects on the sound being processed; in fact, recording engineers often put significant effort into choosing the placement of microphones such that a pleasing portion of a source's radiation pattern and initial reflections may be captured during recording.\",\n \"This convolution template design technique may apply this subtlety and correspondence to naturally occurring sound phenomena.\",\n \"While convolution responses longer than approximately 50 milliseconds in duration may be perceived temporally by the human auditory system, convolution responses shorter than this may be heard spectrally in that they tend to alter the perceived character of the sound being convolved with the response rather than introducing new, separate sounds.\",\n \"The effect of summing multiple, repeated copies of a single signal on that signal's spectrum may be known as comb-filtering.\",\n \"In comb-filtering, a series of evenly spaced frequencies may be cancelled in the signal's spectrum because the contributions from the multiple delayed copies of the input signal at those frequencies may be out of phase and sum to zero.\",\n \"In general, this type of comb-filtering may be largely imperceptible to humans (although particular types of comb-filtering that change systematically over time do, however, form a class of obvious audio effects known as flanging and phasing).\",\n \"The fact that this type of filtering does not create blatantly obvious changes in the character of a sound may be likely because it may be so commonly encountered in natural acoustic spaces, as discussed above.\",\n \"By enforcing a period of silence around the zero-delay component of convolution templates and applying otherwise subtle or low-level responses, the frequency response of the templates tends to occupy this space of comb-filter-like responses that alter the character of the filtered sound in only subtle ways.\",\n \"In addition to this convolution-based method of modifying the input signal, the input signal may also be modified through the momentary addition of specific noise-like signals, y-noise.\",\n \"These noise signals may be added at times determined by the results of the input signal content analysis, such as during or slightly before transient peaks.\",\n \"This novel procedure may be intended to achieve the goal of auditory stress reduction in a manner similar to that of pre-signal content in convolution templates: the addition of a specific noise-like signal may be designed to prime the auditory system for sudden changes in signal energy and to soften the momentary auditory stress induced by sudden changes in signal energy.\",\n \"Again, due to the phenomena of temporal and simultaneous masking, such additions may not be expected to result in obviously different sounds, despite the fact that they may present a listener with markedly different acoustic signals.\",\n \"In some embodiments of the present subject matter, the addition of filtered noise may seem analogous to processing performed by generalized lossy perceptual audio compression schemes.\",\n \"Lossy perceptual audio compression techniques can generally be interpreted as adding spectrally shaped noise to recorded digital audio signals that may not be readily audible.\",\n \"However, this interpretation may be based on a typical method for analyzing the results of quantization and does not fully describe the processing performed by such systems.\",\n \"In practice, these systems quantize information about the input signal such as its spectrum during successive blocks of time with varying resolutions, which may result in highly objectionable audible artifacts and correlations between the input signal and resulting quantization error that cause the additive-noise based interpretation to be inaccurate.\",\n \"Furthermore, when considered as adding spectrally shaped noise to the recorded digital audio signal, these compression technologies add broadband noise over the full duration of the audio signal.\",\n \"In contrast to generalized lossy perceptual audio compression techniques that seek to decrease the amount of data required to represent the digital audio signal, this method may be used to improve the experience of listening to an acoustically reproduced version of the audio signal.\",\n \"To improve the listening experience, specifically shaped noise sequences may be added to the input signal only at specific noise times and for specific noise durations in order to decrease the stress experienced by the auditory system at those moments, where the noise durations may make up a small portion of the duration of the input signal.\",\n \"This use of additive noise also differentiates it from simulations of tape or vinyl mediums that introduce noise during the full duration of an audio signal in order to simulate properties of those recording media.\",\n \"Digital Signal Processing of Priming Signal: Automatic and Signal-Aware Control of the Modification Methods In various embodiments, the modification operations discussed above may be controlled automatically by the results of signal content analysis performed on the input signal.\",\n \"This analysis aims to assess four main characteristics of the input signal: the distribution and complexity of its momentary spectral content, the program, or average, perceived loudness of the signal, the presence of transient bursts of energy or changes in signal content, and, when used on multi-channel recordings, the spatial relationships of these characteristics across the multiple channels.\",\n \"The results of these analyses in turn drive a rule-based control system that may be designed to provide processing that, at any given moment, reduces the stress experienced by the auditory system of a listener while remaining transparent and not obviously audible.\",\n \"In exemplary embodiments of the subject matter, this rule-based control system may consist of a digitally stored look-up table, a set of parameterized functions, or a combination of the two, which relate the outputs of the analysis subsystems to the operation of the modification system components.\",\n \"While in general this control of the modification processes may be performed without intervention from a human operator, in one exemplary embodiment of the subject matter an operator or application that uses the presently disclosed subject matter may specify one or more high-level operation control parameters prior to applying it to a digital audio signal.\",\n \"Such high-level parameters may describe the kind of content being processed or the type of playback system that may be used to listen to the generated output signal.\",\n \"With the caveat that higher-level specifications may adjust the interpretations of each analyzed signal characteristic, we may now describe how the outputs of these signal characteristic analyses may be used to control the signal modification processes.\",\n \"Due to the frequency-dependent nature of many auditory processing phenomena such as masking, analysis may be performed to determine the distribution and complexity of the input signal's momentary spectra.\",\n \"This analysis, in turn, guides the determination of which convolution templates to use as well as the relative mixing gains applied to the outputs of each convolution, and, when deemed appropriate by other analyses, the type of noise signal to add to the input.\",\n \"Convolution templates and noise signals may be chosen to complement the current input signal content and to avoid creating obvious audible effects.\",\n \"Modifications that introduce too much content at frequencies that may not be strongly present in the input signal or that may become obvious due to simple, non-complex material may be avoided.\",\n \"Because the behavior of the human auditory system may be non-linear and generally responsive to relative changes in energy levels, the analysis system estimates the program level, or the average perceived loudness, of the input signal over time.\",\n \"For most audio signals, this estimate may vary gradually with changes in signal content.\",\n \"Relative changes in program level or comparisons between the estimated program level and the known average program level of typical audio recordings (which may vary with the genre of music or type of content contained in the audio signal) may then be used to guide control of the input signal modification system.\",\n \"For example, characteristics such as the pre-signal lead-time used by convolution templates, the relative amount of processed signal mixed with the raw input signal, and the choice of convolution templates may all be affected by the estimated program level.\",\n \"Audio transients, or short-duration changes in audio signal energy or spectral content, provide a particular kind of stimulus to the human auditory system that requires special processing by the input signal modification system.\",\n \"In order to enable such special processing, the input signal may be analyzed to detect transient events in the audio stream.\",\n \"Once detected, a transient event may be further analyzed for relative energy content, spectral make-up, and duration.\",\n \"Among other things, the detection of these events may control the choice of convolution templates and corresponding mixing gains, the amount of pre-signal lead-time used by the convolution templates, the addition of momentary noise-like signals to the input signal, and the enforcing of a duration of silence around the zero-delay time in convolution templates.\",\n \"Finally, because digital audio signals may be commonly reproduced on multichannel systems (with stereo, or 2 channel, systems being the most common), an awareness of the spatial image created by multiple signals may be required to avoid introducing changes into the individual audio signals that result in obvious or undesirable effects, where the changes may be perceived when a user listens to the combined output signals through such a multichannel system.\",\n \"When processing audio signals intended for multiple-channel playback, all channels may be processed together.\",\n \"A higher-level analysis that takes as its inputs the single-channel analysis results may be performed, and the output of this higher-level analysis may be used as an additional control input to the single channel modification systems.\",\n \"The result may be that different modifications may be made to each individual input signal than would have been made were the input signals processed in isolation; the control of the modification system must respect an additional set of rules to ensure that the interaction between multiple channels during playback does not have undesirable effects.\",\n \"Digital Audio Processing for the Restoration of Motion and Dynamic Timbre The sense of motion, liveliness, and spatial dynamics may be simulated using various methods discussed in this document.\",\n \"These methods may compensate for the static presentation of sound created by modern recording and sound synthesis techniques and common modern playback equipment such as headphones and ear buds in order to create a more natural, immersive, and enjoyable listening experience.\",\n \"Modern recorded music and sound, unlike naturally produced acoustic sound, may be spatially and timbrally static.\",\n \"Perhaps the most pervasive recording technique in modern audio production may be to record musical performances in a close mic'd manner, meaning that one or more microphones may be placed at static positions close to a musician or sound source and a performance may be recorded with minimal motion being made by the musician in order to produce a consistent loudness and tone across the duration of the recording.\",\n \"While this technique may afford a certain precision in the recording and post-processing of each musician's contribution to a song or musical piece, it deprives the completed recording of the liveliness and timbral dynamics created by motion in more natural performance and listening environments.\",\n \"The use of digitally synthesized sounds in modern recordings can take this dry, static nature to an extreme, producing recorded sound that may be entirely unchanging in tone or character over time.\",\n \"These modern recording techniques and technologies give rise to an unnatural and unpleasant stationary-tone audio-reproduction environment (STARE), in which recorded sound may be experienced as both spatially and timbrally static.\",\n \"In contrast, when performers play together in an acoustic space their movement alters the spatial radiation characteristics of their instruments over time, gradually changing the timbral qualities of their instruments and exciting various resonances and reflections in the space where they may be performing.\",\n \"Additionally, motion of performers on a stage or of listeners in an audience may change the sound heard by everyone in the audience in small or obvious ways.\",\n \"Even subtle motions of an audience member's head may create shifts in the delays and filtering experienced by the various sound components reverberating about a space before reaching their ears, and thus alter the tonal and spatial qualities of the sound that they hear.\",\n \"All of these dynamic effects contribute to a sense of immersion and liveliness that may be desirable to reproduce when listening to recorded audio.\",\n \"Although post-processing of close-mic recorded audio may add reverberation or panning effects that help to approximate this feeling of immersion and motion, these effects still present a sound with static tonal and spatial qualities in the sense that we have discussed here: a sound may be made to occupy some space or originate from some direction, but none of the natural, motion-driven variability that we have discussed here may be restored.\",\n \"Certain pieces of revered and highly sought-out analog recording equipment may come closest to providing an existing remedy for this problem of static recorded sound, as such equipment may be known to create subtle, time-varying changes in the tone and imaging of processed signals due to circuit phenomena such as very-low-frequency shifts in the DC-bias points of internal components caused by transient offsets in audio signals; however, this type of equipment may be expensive and thus may not be available to all producers of recorded music.\",\n \"Furthermore, such currently existing equipment may only provide a portion of the variability and dynamics that may be desirable for the re-creation of natural sound environments and the maximization of listening enjoyment.\",\n \"With the rise of portable music devices and the accompanying increase in the usage of portable playback equipment such as headphones and ear buds, the STARE problem has been taken to an extreme over the past decade: unlike loudspeakers, these personal playback devices prevent even the natural variability in tone that may be associated with a listener moving about a room or turning their head.\",\n \"At the same time, the popularity of close-mic recording techniques and synthesized digital audio has shown no signs of recession.\",\n \"Thus, it may be desirable to introduce digital signal processing techniques that restore a sense of motion and liveliness to digital audio recordings in order to improve the experience of listening to modern digital audio.\",\n \"A method for processing digital audio signals in order to restore a natural sense of motion and liveliness may be disclosed.\",\n \"The method consists of analyzing a digital audio recording and applying time-varying phase shifts, inter-aural delays, filtering, and amplitude and frequency modulation (e.g., “flutter,” “wow”) in a subtle way that may be driven by the presence of particular signal characteristics, such as percussive or transient events, that help to make the applied processing non-obvious.\",\n \"This method may compensate for the static tonal and spatial listening experience created by modern recording techniques, digitally synthesized sounds, and popular personal playback devices such as headphones and ear buds.\",\n \"This method may improve the experience of listening to digital audio recordings by restoring a sense of motion and immersion to those recordings that may be commonly experienced in live acoustic settings.\",\n \"FIG.\",\n \"9 illustrates an exemplary multichannel analysis signal-modifying processing subsystem 900, according to various embodiments of the present subject matter.\",\n \"Subsystem system architecture 900 demonstrates the general system architecture, consisting of a signal-analysis and processing-control subsystem and a signal-modifying processing subsystem, each of

general, any available data may be analyzed and used to determine the exact modifications to be made to the digital audio signals at each point in their durations, though the presence of transient changes in intensity or energy associated with percussive sounds may play a large role in determining when modifications may be to be made because such sounds have the ability to help mask the applied modifications and make them non-obvious.\",\n \"Each channel in a multichannel processing system, from channel one 920 to channel N 925, may include multiple processing blocks.\",\n \"For example, channel one 920 may be processed through a frequency-dependent phase shift processing block (e.g., all-pass cascade processing block) 930, a linear relative-delay block 940, a magnitude filtering block 950, and an amplitude and frequency modulation block 960.Each processing block may be modified by control data 970, where control data 970 controls processing parameters within each processing block.\",\n \"Processing may be governed by parameterized equations that relate numerical results of signal analysis to parameters controlling the signal modification algorithms.\",\n \"The output of the processing blocks for each channel may be output from the subsystem 900 as output analysis results 980.Additionally, output analysis results 980 may be used to select a particular modification algorithm from a collection of available, implemented algorithms for use on a particular signal or time-region of a signal through some logical or rule-based processing of output analysis results 980.Implementation of the relationship between signal analysis and modification may be controlled or adjusted by higher-level parameters to select a particular relationship from a collection of options: for example, a high-level analysis of the input signals may determine the type of audio content that may be currently being processed (a general, individual instrument or some identified particular instrument, a complex sound mixture of multiple instruments, a sound mixture identified to belong within a particular genre of music, etc.)\",\n \"and use this determination to choose a particular relationship between analysis output and modification from a collection of relationships that may be each most appropriate for a certain type of content.\",\n \"Such high-level control and any lower level parameters of the relationship between analysis and modification may be exposed to an end-user through some type of interface for manual adjustment, or may be performed automatically.\",\n \"Once an analysis configuration and relationship between output analysis results 980 and signal modifications has been determined, time-varying modifications may be made to the input signals 910 to create a sense of motion and liveliness in the recorded audio, thereby improving the experience of listening to it during subsequent playback.\",\n \"These modifications may be performed in a way that may be subtle enough to avoid being overtly noticeable by listeners and that may be neutral enough to avoid altering the creative content of the audio recording, while still creating an appreciable, pleasing effect.\",\n \"Significant motion effects may be achieved within the all-pass cascade processing block 930.The all-pass cascade processing block 930 may introduce time-varying, frequency-dependent phase shifts, potentially applying different shifts to each channel in a stereo or multichannel recording.\",\n \"Such modifications can be performed using digital all-pass filtering, using filters with transition frequencies and orders that vary over time.\",\n \"It has been demonstrated in psychoacoustics experiments that the effects of such phase shifts, which correspond to sound components moving closer and further away, can be perceptually subtle when compared with magnitude, or non-all-pass, filtering.\",\n \"To reduce the perception of the phase shift, a bandpass filter may be used to avoid shifting the phase of the bass or treble.\",\n \"The bandpass filter may include frequencies ranging from 500 Hz to 5 KHz.\",\n \"This provides a neutral and subtle way of animating sound content.\",\n \"In various embodiments of the presently disclosed subject matter, changes in imposed phase shift may often occur in-sync with percussive audio transients, with the amount of shift increasing during transients and then slowly drifting back toward zero over the course of approximately 200 to 500 milliseconds, or in a semi-periodic cyclical fashion at a similar rate.\",\n \"The linear relative-delay block 940 may modify digital audio recordings in order to instill a sense of motion may be using time-varying inter-aural delays.\",\n \"When a sound source moves about a space relative to a listener or a listener rotates their head relative to a source, varying amounts of delay may be experienced by sound as it travels to the listener's left and right ears.\",\n \"Because of this, applying small, time-varying amounts of relative delay between the left and right channels of a stereo audio recording or among multiple channels in a multichannel recording can create a sense of movement and variability similar to the motion that naturally occurs when listening to a live performance.\",\n \"Because listeners have been found in psychoacoustics experiments to be able to detect horizontal displacements of less than one degree in the horizontal plane, the relative delays imposed by the modification system in this way need not be large in order to create a sense of motion.\",\n \"In fact, using too large a modification may be likely to be distracting and prevent the desired subtlety.\",\n \"Various embodiments may impose time-varying relative linear delays of approximately 0.1 millisecond or less across channels in a stereo or multichannel recording.\",\n \"As with imposed frequency-dependent phase shift, the amount of applied relative linear delay may vary in-sync with percussive or transient audio events, or may oscillate in a semi-periodic fashion that may be more loosely driven by signal properties.\",\n \"The magnitude filtering block 950 may be used to simulate a radiation pattern corresponding to motion of an audible source or listener.\",\n \"The radiation pattern of a sound source may change in response to the motion of performers around it or the way that a performer makes contact with it, and the transfer function from a source to a listener due to the acoustic space that they occupy may change significantly as either person moves about or rotates within the space.\",\n \"Typically, these phenomena may give rise to general changes in timbre that may be simulated using low-order IIR (infinite impulse response) filters with transition or cut-off frequencies and gains that change over time or comb-filtering effects caused by the summation of multiple reflections of sound that can similarly be modeled using digital FIR (finite impulse response) or IIR filters that change over time.\",\n \"Both of these types of filters may be designed to produce subtle effects, and thus provide the types of modification desired by the presently disclosed system; by varying their application in response to characteristics of the input signal, such magnitude-filtering may be performed in a way that creates a sense of motion and liveliness without becoming obvious or altering the creative content of the modified recording.\",\n \"The amplitude and frequency modulation block 960 may be used to impose subtle time-varying amplitude modulation (e.g., “wow”) and frequency modulation (e.g., “flutter”) on digital audio recordings in order to create an enhanced sense of motion and dynamics.\",\n \"These effects may be familiar in the audio world because they result from imperfections in common analog playback systems, such as tape and vinyl While these effects may be overt, distracting, or detrimental to playback quality, they may be used subtly to create neutral and subliminal but perceivable motion and complexity in an audio recording.\",\n

may be driven by the analysis of input signal and may vary in response to the low-passed energy envelope of the signal, the presence of discrete, identified transients, momentary spectral complexity,

level-dependent shifts in the perceived pitch of audio content.\",\n \"These corrections compensate for the effects of sound level on perceived pitch, corrections that may be impractical to apply during performance or recording.\",\n \"These corrections may improve the experience of listening to digital audio recordings by adjusting the perceived pitch of an audio signal dynamically.\",\n \"The dynamic adjustment may be dependent upon the momentary loudness of the audio signal (e.g., audio signal intensity, audio signal power, audio signal level, audio signal volume).\",\n \"The concept of auditory or musical pitch may be a perceptual one: while the pitch of a sound tends to be strongly related to mathematical properties of the associated acoustical wave such as its periodicity or frequency content, the relationship between such numerical properties and the perception of pitch may be more complex.\",\n \"Significant research into this relationship was performed in the 1930's at various academic institutions and at Bell Labs, and this research revealed a strong interaction between the level at which a sound may be heard and its perceived pitch, meaning that the same sound heard at different levels or volumes may be perceived as having different pitches, even when no other mathematical properties of the sound signal (such as periodicity or frequency content) have changed.\",\n \"At that time, studies were performed that further elucidated this relationship between sound level and pitch.\",\n \"It was demonstrated that the amount of shift in perceived pitch for a given change in sound level may be dependent upon a complex interaction of signal characteristics, including the frequency content and absolute level of a sound.\",\n \"One trend characterizing this relationship may be that for a simple tone (e.g., single frequency sinusoid), as level increases, the perceived pitch of that tone decreases for frequencies below about 2000 Hz and increases for frequencies above about 2000 Hz.\",\n \"A general characterization of the relationship between the level, frequency content, and perceived pitch of complex sounds (sounds with multiple frequency components) has not been fully characterized for all complex sounds.\",\n \"However, it was found that the shifts in perceived pitch that occur for complex sounds at varying levels may be predicted by a weighted mean of the shifts that would occur for each sinusoidal component of the sound if they were heard individually.\",\n \"This finding suggests that, because many sounds produced by musical sources contain frequency content both above and below the zero-shift frequency of about 2000 Hz, most musical audio material may demonstrate small shifts in perceived pitch with changes in level relative to the shifts demonstrated by simple tones.\",\n \"This phenomenon, that perceived pitch may be dependent upon sound level, poses a subtle problem for musicians and recording engineers.\",\n \"Generally, musicians optimize the tuning of their instruments and their playing techniques to compensate for this effect when performing live together in a group.\",\n \"Such adjustments may be subconscious or habitual rather than overt and deliberate, with professional musicians constantly making minute adjustments based on instinctual knowledge of their instruments and the feedback provided by their perception of pitch; however, it may be common in modern recording workflows for musicians to record their contributions to a song in isolation so that the individual sounds may later be layered or mixed together to form a final recording by a mix engineer, as this affords much more flexibility for adjusting the individual recordings and applying post-processing to individual sounds.\",\n \"In this case, performing musicians cannot make the same adjustments to ensure that all parts of the resulting sound mixture may be perceived to have their desired pitches.\",\n \"Additionally, many instruments do not provide musicians with the capability of making such subtle adjustments to the perceived pitch of the sound they produce, meaning that regardless of the recording situation there may be room for improvement through post-processing of recordings to make these adjustments.\",\n \"Finally, when numerical tools such as frequency content analysis may be relied upon to tune instruments or later adjust the tuning of recorded sounds, this may not compensate for the phenomenon of perceived pitch may not be solely determined by frequency content may be usually neglected.\",\n \"This may result in sounds that may be in need of further dynamic pitch adjustment to achieve or maintain desired musical pitches.\",\n \"Because the perceived pitch of musical sound plays a large role in its emotional impact and perceived quality, even minor pitch adjustments may have a noticeable impact on the listening experience.\",\n \"Research into psychoacoustics has demonstrated that the perceived pitch of a sound may be effected by the level at which that sound may be heard, meaning that minor adjustments to produced sounds may be required to sustain a particular pitch across differing sound levels.\",\n \"Because modern recording techniques make it difficult or impossible for musicians to make these adjustments during performance and because such adjustments may not be possible, using digital signal processing techniques to apply dynamic, level-dependent adjustments to the pitch of recorded digital audio, when appropriate, may greatly enhance the listening experience.\",\n \"A method for processing digital audio signals in order to correct for level-dependent shifts in the perceived pitch of audio content may be disclosed.\",\n \"The method consists of analyzing a digital audio recording and creating small, dynamic shifts in perceived pitch as required to compensate for the pitch distortion caused by relative changes in momentary sound level.\",\n \"This method may be suitable for processing of any type of digital sound recording, including individual sound recordings and complex sound mixtures.\",\n \"This method may compensate for modern recording techniques that make it difficult or impossible for musicians to make such adjustments correctly in produced pitched during recorded performances and to improve the perceived pitch of recorded digital audio across changes in relative level wherever possible.\",\n \"By correcting these small pitch distortions, the perceived quality of digital audio recordings may be improved without altering their creative content.\",\n \"FIG.\",\n \"10 illustrates a series single-channel analysis subsystem 1000, according to various embodiments of the present

small, such as in the range of a shift in frequency of 0.015 to 1.15 percent (e.g., 0.25 to 20 cents, where 100 cents represents the difference between each semitone within an octave).\",\n \"These small pitch shifts may be in accordance with the small perceptual shifts in pitch that occur for complex musical sounds with relative changes in level, and different amounts of pitch or frequency shift may be applied to separate spectral bands of the input signal.\",\n \"In one embodiment of the presently disclosed subject matter, positive pitch-shift may be applied to signal content at frequencies above about 2000 Hz as signal levels fall below a nominal reference level in order to compensate for the decrease in perceived pitch that occurs for sinusoidal components in this frequency range as level decreases.\",\n \"In another embodiment of the subject matter, the input signal may be split into numerous frequency bands and varying amount of pitch or frequency shift may be applied

the input signals or portions of the input signals (isolated frequency bands, for example) to achieve the desired changes in perceived pitch, as determined by signal analysis.\",\n \"If multiple algorithms were implemented and made available to the operator, the operator may determine which algorithm may be best suited to a particular bit of audio signal.\",\n \"Alternatively, analysis of that audio signal may be used to determine automatically which algorithm may be best suited to each portion of audio signal.\",\n \"Multiplexed Convolution A multiplexed convolution signal processing architecture applies multiple distinct types of processing to an input signal simultaneously in an adaptive, signal-aware way through the calculation of one or more time-varying convolutions.\",\n \"The convolution kernels may be associated with points in a multidimensional behavior space, where coordinates correspond to parameters of the distinct processes being implemented.\",\n \"The values of these parameters change over time in response to input signal properties, adaptively changing the convolution kernels and thus the results of processing.\",\n \"In the present case, such processing may be achieved through the calculation of generalized convolution operations between an input signal and a time-varying convolution kernel, where the content of the kernel varies in response to properties of the input signal.\",\n \"The mathematical operation of convolution between two functions, (f*g)(t)≡∫−∞∞f(τ)g(t−τ)dτ, (8) may be fundamental to linear systems analysis and may be well known in a variety of fields, including the field of signal processing.\",\n \"The output of any linear time-invariant (LTI) system may be defined for arbitrary input signals as the result of convolution between those input signals and a function known as the system's impulse response.\",\n \"This input-output relationship provides an extremely concise and powerful way of mathematically characterizing a broad class of systems that may be commonly encountered in the physical world and that may be frequently used in an endless variety of applications.\",\n \"In more common notation, this relationship can be expressed as (y)(t)≡∫−∞∞h(τ)x(t−τ)dτ, (9) for an input signal x(t), time-invariant system impulse response h(t), and corresponding output signal y(t).\",\n \"The convolution defined in equation (8) and equation (9) may be a linear operation and thus cannot be used directly to implement nonlinear processing.\",\n \"However, it may be possible to formulate the input-output relationship of a system whose behavior varies over time in response to characteristics of the input signal as a form of generalized convolution that may achieve nonlinear system behavior.\",\n \"The main difference between such an alternative formulation of convolution and the standard definition presented in equation (8) may be that the two functions, f and g, do not remain independent of one another.\",\n \"In terms of the more standard linear system notation presented in equation (9), the system response h(t) becomes dependent upon not just time t, but the input signal x(t) itself.\",\n \"While this introduced dependence may make the analysis of overall system behavior much more complicated, it also creates the possibility for more complex system behavior such as nonlinear processing.\",\n \"For example, we may use the definition (y)(t)≡∫−∞∞H{SHIFT−t{X}}(τ)x(t−τ)dτ, (10) where H{⋅} and SHIFTt{⋅} define operators whose domains may be the set X of all functions x with the real numbers as both their domain and range, X={x|x: R→R}, and whose ranges may be the same set of functions, written as H: X→X and SHIFTt: X→X.\",\n \"In this case, the operator H{⋅} defines the relationship between the input signal x(t) and the system response h(t) in a general way, and the operator SHIFTt{⋅}, defined as SHIFTt{X(α)}≡X(α−t), (11) serves the purpose of making the input-output relationship of the overall system time-invariant, meaning that the relationship between the input signal x(t) and the system response h(t) defined by H{⋅} takes into account only relative differences in time between input and output and has no sense of overall time.\",\n \"The generalized convolution operation defined in equation (10) characterizes the dynamic system through a particular kind of time-varying system function known as an input delay-spread function, albeit one that has the unusual property of being dependent upon the input signal itself.\",\n \"A similar definition with slightly different behavior may be written as (y)(t)≡∫−∞∞H{SHIFT−(t-τ){X}}(τ)x(t−τ)dτ, (12) where the dynamic system may be instead characterized through a time-varying system function known as an output delay-spread function.\",\n \"The difference between these types of time-varying system functions may be in whether the particular system function at time t, ht(τ), may be constant for a time t associated with the output signal being calculated or with the input signal being used to calculate the output.\",\n \"Otherwise, both definitions capture the same dependence of system behavior upon the input signal x(t) and provide essentially the same definition of a generalized convolution operation.\",\n \"The system definitions given in equations (10) and (12) make it possible to achieve both linear and nonlinear system behavior with the same general system architecture, and thus provide a unifying framework through which multiple different processes may be applied to a signal simultaneously; however, this type of general, dynamic system description has not been used to unify multiple simultaneous processes in this way previously.\",\n \"Because multiple distinct processes performed on an input signal can interact in complex ways when some of the processes may be nonlinear, and because various system architectures may exhibit different behavior when made to be time-varying, it may be desirable to devise such a unified system so that all individual processes may be controlled simultaneously in a way that takes their interactions into account and allows for the desired overall processing to be consistently achieved when making changes to parameters of one or more of the individual processes.\",\n \"A method for processing digital signals in order to simultaneously implement multiple linear and/or nonlinear processes in a general way that allows for control of interactions between each stage of processing and adaptive, signal-aware system behavior is disclosed.\",\n \"The method consists of defining a range of system behaviors, each designed to achieve the best overall processing results associated with a set of parameter values describing the individual implemented processes, and then analyzing input signal properties to determine the desired values for these parameters at each moment in time.\",\n \"The connection between analysis results and system behavior may be described by a multidimensional system-behavior space in which coordinates correspond to parameters of the distinct processes being implemented: Each designed system behavior may be associated with a point in this space, and analysis of input signal properties determines where in the space the system should currently be operating.\",\n \"All possible system behaviors may be described in a consistent and general way as one or more generalized convolutions whose outputs may be combined to generate the system output, allowing for smooth transitions and interpolations between specified system behaviors, control of interactions between the various implemented processes by way of total system behavior specification, and consistent time-varying behavior across all implemented processes.\",\n \"A unified system may simultaneously implement multiple linear and/or nonlinear processes in a manner that may be time-varying responsive to various characteristics of the input signal.\",\n \"Because processes implemented through different architectures may exhibit inherently different behavior when made to be time-varying and because the interactions between multiple stages of processing may be complex when nonlinear processes may be performed, such a unified system may be intended to allow for more consistent and detailed control of overall system behavior when multiple processes may be to be applied to an input signal simultaneously in a time-varying, signal-aware manner.\",\n \"A system that processes digital signals in a way

impulse responses, which may be then combined and evaluated according to the indicated output topologies in order to form the system output.\",\n \"While FIG.\",\n \"19 shows a simple example, more complex embodiments may require the storing and interpreting of additional metadata for each process and response.\",\n \"In order to enable the simultaneous implementation of several types of processing in this continuously time-varying and general way, all possible system behaviors may be discussed using a consistent, general architecture: at all times, the system performs one or more generalized convolutions with input signals and combines the results of these convolutions according to a topology consisting of series and parallel connections to form the output signal.\",\n \"Thus, each point in behavior space dictates a set of generalized convolution kernels and a topology for combining the convolution outputs.\",\n \"These convolution kernels and combination topologies may be designed to best achieve the overall processing results specified by the associated set of individual process parameters, taking possible interactions between processes into account, and may be designed to vary in such a way across nearby points in behavior space that overall system behavior may be guaranteed to vary smoothly while changing in response to properties of the input signal.\",\n \"By describing the overall system behavior in this way, the system may be able to manage interactions between multiple individual processes.\",\n \"It may be often easiest to describe a desired overall processing system as a signal-flow graph consisting of several discrete, well-understood parts that each serve a particular function.\",\n \"However, complicated interactions between the effects of these individual processes in the presence of nonlinearity generally dictate that when the parameters of one process may be changed, the parameters of other processes must also be changed in order to compensate and keep their contribution to the overall system equivalent.\",\n \"These compensating changes may be difficult to derive for many multi-process systems when using common parameterizations and implementation architectures for each discrete process, which may vary significantly depending on the type of process being implemented.\",\n \"Further complication arises when imposing time-varying behavior on a multi-process system in which the various processes may be implemented using different architectures, as each individual architecture may have unique restrictions on its ability to change over time and may produce varying artifacts or undesirable consequences when changing configuration or parameter values.\",\n \"In order to allow better time-varying control of multiple simultaneous processes, an alternative approach may be used to control overall system behavior through the adjustment of individual process parameters.\",\n \"In particular, the desired overall system behavior for each combination of individual process parameters may be specified through the use of one or more generalized convolutions that may or may not reflect various discrete processing components, and that can be designed without the restrictions of discrete component parameterizations in order to better maintain overall desired system characteristics.\",\n \"The system response kernels for these convolutions can then be made to vary smoothly in response to changes in individual process parameters, allowing the system behavior to change smoothly over time and in a way that preserves the desired overall processing across all possible behavior trajectories without the need for directly analyzing the complex interactions between individual processes.\",\n \"Furthermore, by implementing all processing as generalized convolutions, overall system implementation may be simplified: various processes may be achieved using varying generalized convolution kernels rather than varying architectures and techniques, and consistent time-varying behavior can be achieved across all processes in the system.\",\n \"Additional analysis and modifications are discussed below in more detail.\",\n \"Multiplexed Convolution: Adaptive, Signal-Aware Control of System Behavior The first step in determining the system response at any particular moment in time may be to determine where, in behavior space, the system should be operating based on the current input signal content.\",\n \"If we denote the location of the system in behavior space at time sample n as θ[n], we can express this procedure as evaluating part of the operator H{⋅} presented in equation (10) as θ[n]=Hθ{SHIFT−n{X}}, (13) where H{⋅}=Hh{Hθ{SHIFT−n{X}}} (14) gives a decomposition of the relationship between input signals x and system response h, denoted as H{⋅}, into two separate steps: one operation which analyzes signal properties and maps to a point in system behavior space, Hθ{⋅}, and another operation which maps from that point in system behavior space to a description of system behavior in terms of generalized convolution kernels and system topology, Hh{⋅}.\",\n \"Here, our behavior space, which we may refer to as Θ, may be a p-dimensional space, where p may be the number of parameters characterizing the operation of the system, and we have that θ[n]ϵΘ for all n.

signal analysis and Hθ{⋅} as separate blocks.\",\n \"This may be caused by embodiments of the presently disclosed subject matter in which the types of signal analyses performed and the way that their results map into behavior space may be separable, such as depicted in FIG.\",\n \"18.However, it may be more useful to describe Hθ{⋅} as representing all processing from input signals to θ[n].\",\n \"In general, any available data may be analyzed and used to determine the value of θ[n] at each point in time, including additional metadata supplied to the presently disclosed system separately from the input signals themselves.\",\n \"Furthermore, the relationship between analysis results and θ[n], represented by Hθ{⋅}, may itself be controlled or adjusted by higher-level parameters resulting from signal analysis or external controls.\",\n \"Depending on the particular implementation, this may be thought of as selecting one Hθ{⋅} from a collection of options or as warping the function mapping between signal analysis results and points in behavior space by some additional operation W: Θ→Θ, as W{Hθ{⋅}}.\",\n \"An example of a high-level parameter that might be used in this manner would be a specification of the general type of digital signal being processed, either determined through automatic classification or through manual specification by an operator prior to processing.\",\n \"This capability of altering Hθ{⋅} itself may be most applicable to embodiments of the presently disclosed subject matter that may be used for processing numerous types of signals,

is etched into desired patterns.","The process steps commonly include physical vapor deposition (PVD), chemical vapor deposition (CVD), plasma enhanced CVD (PECVD), and other plasma processing.","Specifically, a plasma process requires supplying a process gas mixture to a vacuum chamber, and applying electrical or electromagnetic power (RF power) to excite the process gas into a plasma state.","The plasma decomposes the gas mixture into ion species that perform deposition, etch, implant or other processes.","One problem encountered with plasma processes is the difficulty associated with establishing uniform plasma density over the substrate surface during processing, which leads to non-uniform processing between the center and edge regions of the substrate and non-uniform processing azimuthally within center and edge regions.","One reason for the difficulty in establishing uniform plasma density involves gas flow skews due to asymmetry in the physical process chamber design.","Such skews not only result in naturally, azimuthal, non-uniform plasma density, but also make it difficult to use other processing variables or “knobs” to control center-to-edge plasma uniformity.","Therefore, a need exists for a plasma processing apparatus that improves gas flow symmetry for improved plasma uniformity control.","SUMMARY Embodiments of the

non-symmetry caused by a slit valve door.","In one embodiment, a flow asymmetry may be introduced in the flow equalizing assembly to compensate for RF asymmetry to obtain processing symmetry.","The flow equalizing assembly enables the symmetry of fluid flow in a processing chamber to be tuned, thus, reducing processing skew and improving uniformity of processing.","FIG.","1A is a schematic sectional view of a plasma processing chamber 100 according to one embodiment of the present invention.","The plasma processing chamber 100 includes a flow equalizer assembly 160 to obtain fluid flow symmetry between a processing volume and a vacuum port.","The flow equalizer assembly 160 may be used to obtain a symmetrical fluid flow, or may be used to tune the symmetry of the fluid flow to compensate for other chamber asymmetries to obtain symmetrical processing results.","The plasma processing chamber 100 may be configured to process a variety of substrates, such as semiconductor substrates and reticles, and accommodating a variety of substrate sizes.","The plasma processing chamber 100 includes a chamber body 110.A bottom chamber liner 112 and a top chamber liner 114 are disposed inside the chamber body 110.The bottom chamber liner 112, the top chamber liner 114 and a chamber lid 116 define a chamber volume 118.Slit valve openings 119, 120 may be formed through the chamber body 110 and the top chamber liner 114 to allow passage of a substrate 102 and substrate transfer mechanism (not shown).","A slit valve door 122 may be utilized to selectively open and close the slit valve openings 119, 120.A substrate support assembly 124 is disposed in the chamber volume 118.The substrate support assembly 124 has a substrate supporting surface 126 for supporting a substrate thereon.","A lift 132 may be coupled to lifting pins 134 to raise the substrate 102 from and to lower the substrate 102 on to the substrate support assembly 124.The substrate support assembly 124 may be an electrostatic chuck coupled to a chucking power source 136 to secure the substrate 102 thereon.","The substrate support assembly 124 may also includes one or more embedded heating elements coupled to a heating power source 138 for heating the substrate 102 during processing.","A cooling fluid source 140 may provide cooling or heating and adjust temperature profile of the substrate 102 being processed.","An optional plasma screen 130 may be disposed surrounding the substrate support assembly 124.The plasma screen 130 may be positioned at a vertical level similar to the vertical level of the substrate supporting surface 126 and separates the chamber volume 118 into a processing volume 118a and a lower volume 118b located below the plasma screen 130.A showerhead assembly 142 may be positioned above the processing volume 118a to deliver one or more processing gases from a gas delivery system 144 to the processing volume 118a.","Alternatively, the plasma processing chamber 100 may also include an antenna assembly for generating inductively coupled plasma in the plasma processing chamber 100.A vacuum pump 150 is in fluid communication with the chamber volume 118 to maintain a low pressure environment within the processing volume 118a.","In one embodiment, the vacuum pump 150 may be coupled to the lower chamber volume 118b through a vacuum port 152 formed in the bottom chamber liner 112.As shown in FIG.","1A, the vacuum port 152 is positioned at a bottom of the lower volume 118b and laterally offset from the substrate support assembly 124, and thus, the vacuum port 152 is located non-symmetrical relative to the substrate support assembly 124.The flow equalizer assembly 160 is disposed around the substrate support assembly 124 to azimuthally equalize the gas flow passing from the processing volume 118a to the lower volume 118b.","In one embodiment, the flow equalizer assembly 160 may be disposed under the optional plasma screen 130.The vacuum pump 150 pumps out gas and process by products from the processing volume 118a through the vacuum port 152, the lower volume 118b and flow paths formed through the flow equalizer assembly 160.The flow equalizer assembly 160 may include two or more plates 162, 164 spaced apart from one another.","A flow re-distributing volume 172 is defined between neighboring plates 162, 164.Each of the plates 162, 164 includes openings 168, 170 formed therethrough.","During operation, driven by vacuum suction from vacuum port 152, gases and particles exit the processing volume 118a through the openings 170 of the plate 164, flow through the flow re-distributing volume 172, then flow through the openings 168 of the plate 162 towards the vacuum port 152.Numbers, size, and/or locations of the openings 168, 170 are arranged so that flow paths between the openings 170 to the openings 168 through the flow re-distributing volume 172 can be tuned to correct processing asymmetries by either adjusting or eliminating the flow asymmetries between the processing volume 118a and the vacuum port 152.In one embodiment of the present invention, each of the two or more plates 162, 164 may be a circular plate having a central opening for receiving the substrate support assembly 124 so that the flow equalizer assembly 160 is disposed around the substrate support assembly 124.In one embodiment, the top most plate 164 may be at a horizontal level similar to or slightly lower than the substrate supporting surface of the substrate support assembly 124.The openings 170 may be substantially evenly distributed along an outer edge of the substrate support assembly 124.The circular plates 162, 164 may be arranged parallel to each other.","The openings 168 of the plate 162 and the openings 170 of the plate 164 may be arranged in a vertically staggered manner, instead of vertically aligned with each other, to enable flow equalizing within the flow re-distributing volume 172.The number, shape and sizes of openings 168 and the number of openings 170 may be the same or different.","In one embodiment, the number of openings 170 on the plate 164 which is positioned closer

least twice as many as the number of the openings 168.The number, size and/or location of openings in the plates 162, 164 may be arranged to provide equal distances between the vacuum port 152 and different regions of the substrate support assembly 124 so that processing gases within the processing volume 118a can be uniformly and symmetrically pumped around the substrate support assembly 124.FIG.","1B is a schematic top view of the plasma processing chamber 100 of FIG.","1A with the lid 116 removed.","As shown in FIG.","1B, the vacuum port 152 is positioned off center from the centerline of the substrate support assembly 124.The plates 164, 162 are disposed concentric to the substrate support assembly 124.The openings 170 of the top plate 164 may be evenly distributed around the substrate support assembly 124.The number of openings 170 of the top late 164 may be at least twice as many as the number of openings 168 of the bottom plate 162.In the embodiment of FIG.","1B, there are two openings 168 on the bottom plate 162.The two openings 168 are positioned at equal distance away from the vacuum port 152.There are four openings 170 on the top plate 164.The top plate 164 is positioned in an angle so that each opening 170 is located at the substantially the same distance away from a closest opening 168.As a result, each opening 170 on the top plate 164 is positioned at substantially the same distance away from the vacuum port 152, thus reducing the non-symmetry in flow paths through the flow equalizer assembly 160.In the embodiment of FIG.","1B, each of the openings 170 is similar in shape and size and each of the openings 168 is similar in shape and size.","Alternative, the shape and/or size of each opening 170 or opening 168 may be unique or different to provide a target flow resistance.","Although two plates 164, 162 are shown in the flow equalizer assembly 160 of FIG.","1A, additional plates may be included to tune the flow distribution through the flow equalizer assembly 160.For example, an additional plate may be disposed above the top plate 164.The additional plate may have twice as many openings as the top plate 164 to generate a recursive flow splitting and equalizing effect.","FIG.","2A is a schematic perspective view of a flow equalizer assembly 200 according to one embodiment of the present invention.","The flow equalizer assembly 200 includes a first plate 202 having a plurality of openings 204 for receiving fluid flow from a processing volume and a second plate 206 having two or more openings 208 for directing fluid

support assembly.","A sidewall 214 may extend above the first plate 202 from an outer perimeter.","The sidewall 214 may be symmetrical, for example having a circular shape or a normal polygonal shape, to retain a symmetrical volume above the substrate support assembly.","In one embodiment, the sidewall 214 may include an upper lip 215 so that the flow equalizer assembly 200 can be supported by a chamber liner.","A sidewall 216 may connect between the first plate 202 and the second plate 206 to enclose a flow re-distributing volume 218.The sidewall 216 may be symmetrical, for example being circular.","The distribution, shape, size and/or relative locations of the openings 204, 208 and the height of the flow re-distributing volume 218 may be tuned to achieve flow redistributing effect.","The plurality of openings 204 may be evenly distributed along the first plate 202.A spacing 217 between the first plate 202 and the second plate may be provided to achieve targeted flow

distance to the vacuum port.","Since the openings 204 are positioned along an edge region of the plasma or processing environment, the processing environment can be symmetrically vacuumed by the vacuum port through the flow equalizer assembly 200.The two openings 208 closest to the vacuum port may be positioned at equal distances from the vacuum port.","As shown in FIG.","2B, the vacuum port is located at 180 degrees, while the openings 208 are positioned at 90 degrees and 270 degrees respectively.","Similarly, the openings 204 are arranged such that each opening 204 is at substantial the same distance to a closest opening 208.In FIG.","2B, there are four openings 204 positioned 90 degrees apart at 45 degrees, 135 degrees, 225 degrees and 315 degrees.","Additional plates can be positioned above the first plate 202 to provide for further equalizing.","For example, an additional having twice as many openings as the first plate 202 may be positioned above the first plate 202.In the embodiment of FIG.","2B, the openings in the additional plate may include eight openings positioned 45 degrees apart at 22.5 degrees, 67.5 degrees, 112.5 degrees, 157.5 degrees, 202.5 degrees,

cell, raising a pH of the cell and/or contacting the cell with a salt, and separating the lipid.","The present invention is also directed to lipids prepared by the processes of the present invention.","The present invention is also directed to microbial lipids having a particular anisidine value, peroxide value, and/or phosphorus content.","Background Art A typical process for obtaining lipids from a microbial cell, such as polyunsaturated fatty acids, involves growing microorganisms that are capable of producing the desired lipid in a fermentor, pond or bioreactor, separating the fermentation broth comprising a microbial cell biomass, drying the microbial cell biomass, and separating the lipids by solvent extraction.","Steps in the separation can include diluting a fermentation broth with water, centrifuging the diluted broth, lysing the microbial cells, and extracting an intracellular lipid from the lysed cells by adding a water-immiscible solvent to the mixture in which the lipid is soluble, e.g., hexane.","Another method of extraction to remove a lipid from a microbial cell is lysing a cell in a fermentation broth using mechanical force (e.g., homogenization), enzymatic treatment, or chemical treatment to disrupt the cell walls.","Lipid can be extracted from the resulting composition comprising lipids, microbial cell biomass, and water using an organic solvent, e.g., isopropyl alcohol.","The lipid can be separated mechanically from the composition and the alcohol must be removed from both the lipid and the aqueous biomass waste stream.","See, e.g., International Pub.","Nos.","WO 01/76385 and WO 01/76715.However, industrial scale production of lipids using either of the above processes requires a large amount of volatile and flammable organic solvent, thereby creating hazardous operating conditions.","The use of organic solvents in the extraction process can also necessitate using an explosion-proof lipid recovery system, thereby adding to the cost of lipid recovery.","Moreover, use of an organic solvent in extracting lipid from a microbial cell can generate an organic solvent waste stream that requires a complete solvent recovery system or a proper method of disposal, which further increases the overall production cost of lipid extraction.","For example, strict limits on volatile organic compound (VOC) emissions require greater manpower and added cost to vessels and other equipment.","Therefore, there is a need for a process for obtaining lipids from a cell which does not use an organic solvent.","Several processes have been proposed for separating a lipid from a cell without the use of an organic solvent.","For example, U.S. Pat.","No.","6,750,048 discloses an aqueous washing process whereby an emulsion is washed with aqueous washing solutions until a substantially non-emulsified lipid is obtained.","However, in some embodiments, this process requires multiple washing steps, which require substantial cost and time.","U.S. Pat.","No.","7,431,952 discloses a process whereby lysed cells are centrifuged to remove cell wall debris and then oils are extracted and purified.","However, this process provides a crude oil that requires extensive further purification.","Thus, what is needed is a process that does not utilize a volatile solvent to extract a lipid from a cell, and which can be performed using readily available equipment and a minimum number of steps to provide a highly pure lipid.","BRIEF SUMMARY OF THE INVENTION The present invention is

are expected to be the substantially the same if the samples were extracted using the processes of the present invention.","Example 32 After oil was extracted from the fermentation broth using the Friolex process, as described in Example 31, the crude oil was further processed via refining, bleaching, and deodorizing steps to obtain a final oil.","The final oil was diluted with high oleic sunflower oil to obtain finished commercial oil with a DHA content of approximately 400 mg/g.","Individual lipid classes were isolated and the fatty acid profiles of each class was determined using gas chromatography with flame ionization detection (GC-FID) as fatty acid methyl esters (FAME).","Flash Chromatography— Flash chromatography was used to separate the lipid classes present in the final oil, and to determine the weight percent of each class present in the oil.","The chromatography system utilized Silica Gel 60 (EMD Chemical, Gibbstown, N.J.) with mobile phase composed of Petroleum Ether and Ethyl Acetate at 3 mL/min.","A step gradient was used to selectively elute each lipid class from the column.","The mobile phase gradient started from 100% petroleum ether and finished with 50% ethyl acetate (followed by a 100% methanol wash).","Fractions were collected in 10 mL test tubes using a Gilson FC 204 large-bed fraction collector (Gilson, Inc., Middleton, Wis.).","Each tube was analyzed by thin layer chromatography (TLC) and the tubes containing individual lipid classes (as judged by single spots on TLC plate with expected retention factor (Rf)) were pooled, concentrated to dryness, and weighed.","The total fraction content was then determined gravimetrically.","TLC Analysis— Thin layer chromatography was conducted on silica gel plates.","The plates were eluted using a solvent system consisting of petroleum ether:ethyl ether:acetic acid (80:20:1) and were visualized using iodine vapor.","The Rf values of each spot were then compared with reported literature values for each lipid class.","Fatty Acid Analysis— The final oil sample and isolated lipid classes were analyzed for fatty acid composition as FAMEs.","Samples were weighed directly into screw cap test tubes, and 1 mL of C19:0 internal standard (NuCheck, Elysian, Minn.) in toluene and 2 mL of 1.5 N HCl in methanol was added to each tube.","The tubes were vortexed briefly and placed in a heating block for 2 hours at 100° C. The tubes were removed from the heating block, allowed to cool, and 1 mL of saturated NaCl in water was added.","The tubes were vortexed again, centrifuged, and a portion of the top (organic) layer was placed in a GC vial and analyzed by GC-FID.","FAME's were quantified using a 3-point internal standard calibration curve generated using Nu-Chek-Prep GLC reference standard (Nu-Chek Prep, Inc., Elysian, Minn.) and tentatively identified based on retention time.","Fatty acids present were expressed as mg/g and % of total FAME.","The sample was prepared by dissolving 250 mg of final oil in 600 μL of hexane and applying to the head of the column.","After fractionation of the sample using flash chromatography, the sterol ester fraction accounted for 1.2% by weight, the triacylglyceride (TAG) fraction accounted for 92.1% by weight, the free fatty acid (FFA) fraction accounted for 2.1% by weight, the sterol fraction accounted for 1.1%, the diacylglyceride (DAG) fraction accounted for 2.8%

day old flask, approximately 50 ml, was poured into a sterile 40 ml glass homogenizer.","The culture received 50 plunges in the homogenizer.","The culture was pipetted out and filtered through a sterile 50 micron mesh filter, which was placed in a 50 ml sterile tube (the mesh was used as a means of retaining the larger clumps of colonies while letting the smaller clusters and single cells pass through the 50 micron mesh.).","The entire concentrated macerate was collected in a sterile 50 ml tube.","The macerated culture was vortexed and dilutions at levels up to 1:100 fold were made in tubes containing thraustochytrid media.","The diluted macerate samples were vortexed prior to adding 200 μl of inoculum to a thraustochytrid media agar petri dish, 100×15 mm, containing 4-5 glass beads (3 mm glass beads).","Each plate was gently agitated in an effort to have the beads spread the inoculum evenly around the plate.","Beads were dumped off of plates and plates were left to sit with covers on for approximately 5 minutes to dry.","Lights in both the sterile hood and adjoining areas were turned off as the procedure was performed in dim light.","There was minimal light

flask of the isolated microorganisms deposited under ATCC Accession Nos.","PTA-10208 and 10212 was prepared as a carbon and nitrogen-fed culture in media according to Tables 30 and 31.Mutagenesis was carried out according to following procedure: A sterile T=2 day old flask, approximately 50 ml, was poured into a sterile 40 ml glass homogenizer.","The culture received 50 plunges in the homogenizer.","The culture was pipetted out and filtered through a sterile 50 micron mesh filter, which was placed in a 50 ml sterile tube (the mesh was used as a means of retaining the larger clumps of colonies while letting the smaller clusters and single cells pass through the 50 micron mesh.).","The entire concentrated macerate was collected in a sterile 50 ml tube.","The macerated culture was vortexed and dilutions at levels up to 1:100 fold were made.","The diluted macerate samples were vortexed prior to adding 200 μl of inoculum to a media agar plate, 100×15 mm, containing 4-5 glass beads (3 mm glass beads).","Each plate was gently agitated in an effort to have the beads spread the inoculum evenly around the plate.","Beads were dumped off of plates and plates were left to sit with covers on for approximately 5 minutes to dry.","Lights in both the sterile hood and adjoining areas were turned off as the procedure was performed in dim light.","There was minimal light available to be able to run the procedure but only indirect and dim.","Five replicate plates were placed on the floor of the XL crosslinker (Spectronics Corporation, New York) with the lids off while the samples were irradiated.","The crosslinker delivered power in terms of microjoules and a level was sought that achieved a 90%-95% Kill.","Five replicate control plates were inoculated with un-mutagenized cells using the same protocol.","These cell counts were used to calculate the % Kill.","Once the irradiation was finished the plates were taken out, the lids were replaced, and the plates were wrapped in parafilm followed by a wrap in aluminum foil.","It was imperative that the plates grew for the first week in the dark so that they were not able to repair the damaged genes.","Plates were placed in a 22.5° C. room for about 10 days prior to counting the colonies.","When final counts were made, individual colonies were picked with a sterile inoculating loop and re-streaked on new media plates.","Each colony was plated on an individual plate.","As plates grew dense a sample was taken, using a inoculating loop, and inoculated into a sterile 250 ml shake flask containing 50 ml of media.","This flask was placed on a shaker at 200 rpm in a 22.5° C. room.","On T=7 days the shake flask culture was harvested into a 50 ml sterile tube.","The pH was taken and the sample was centrifuged to collect the biomass pellet.","Each sample was rinsed and re-suspended in a 50:50 mixture of isopropyl alcohol and distilled water prior to being re-centrifuged.","The collected pellet was freeze dried, weighed, and a FAME analysis was performed.","The data in Tables 51 and 52 represents mutants produced with the above process from strains PTA-10208 and PTA-10212,

present invention relates to processes for obtaining a lipid from a cell by lysing the cell, raising a pH of the cell and/or contacting the cell with a salt, and separating the lipid.\",\n \"The present invention is also directed to lipids prepared by the processes of the present invention.\",\n \"The present invention is also directed to microbial lipids having a particular anisidine value, peroxide value, and/or phosphorus content.\",\n \"Background Art A typical process for obtaining lipids from a microbial cell, such as polyunsaturated fatty acids, involves growing microorganisms that are capable of producing the desired lipid in a fermentor, pond or bioreactor, separating the fermentation broth comprising a microbial cell biomass, drying the microbial cell biomass, and separating the lipids by solvent extraction.\",\n \"Steps in the separation can include diluting a fermentation broth with water, centrifuging the diluted broth, lysing the microbial cells, and extracting an intracellular lipid from the lysed cells by adding a water-immiscible solvent to the mixture in which the lipid is soluble, e.g., hexane.\",\n \"Another method of extraction to remove a lipid from a microbial cell is lysing a cell in a fermentation broth using mechanical force (e.g., homogenization), enzymatic treatment, or chemical treatment to disrupt the cell walls.\",\n \"Lipid can be extracted from the resulting composition comprising lipids, microbial cell biomass, and water using an organic solvent, e.g., isopropyl alcohol.\",\n \"The lipid can be separated mechanically from the composition and the alcohol must be removed from both the lipid and the aqueous biomass waste stream.\",\n \"See, e.g., International Pub.\",\n \"Nos.\",\n \"WO 01/76385 and WO 01/76715.However, industrial scale production of lipids using either of the above processes requires a large amount of volatile and flammable organic solvent, thereby creating hazardous operating conditions.\",\n \"The use of organic solvents in the extraction process can also necessitate using an explosion-proof lipid recovery system, thereby adding to the cost of lipid recovery.\",\n \"Moreover, use of an organic solvent in extracting lipid from a microbial cell can generate an organic solvent waste stream that requires a complete solvent recovery system or a proper method of disposal, which further increases the overall production cost of lipid extraction.\",\n \"For example, strict limits on volatile organic compound (VOC) emissions require greater manpower and added cost to vessels and other equipment.\",\n \"Therefore, there is a need for a process for obtaining lipids from a cell which does not use an organic solvent.\",\n \"Several processes have been proposed for separating a lipid from a cell without the use of an organic solvent.\",\n \"For example, U.S. Pat.\",\n \"No.\",\n \"6,750,048 discloses an aqueous washing process whereby an emulsion is washed with aqueous washing solutions until a substantially non-emulsified lipid is obtained.\",\n \"However, in some embodiments, this process requires multiple washing steps, which require substantial cost and time.\",\n \"U.S. Pat.\",\n \"No.\",\n \"7,431,952 discloses a process whereby lysed cells are centrifuged to remove cell wall debris and then oils are extracted and purified.\",\n \"However, this process provides a crude oil that requires extensive further purification.\",\n \"Thus, what is needed is a process that does not utilize a volatile solvent to extract a lipid from a cell, and which can be performed using readily available equipment and a minimum number of steps to provide a highly pure lipid.\",\n \"BRIEF SUMMARY OF THE INVENTION The present invention is directed to a process for

parameters on a regular basis in support of any treatment or therapy that he or she is undergoing or receiving.","Today, advances in medical research enable a range of therapeutic options to treat a given disease, or ailment and/or their symptoms, where each of the proposed therapies targets a particular biochemical or physiochemical process underlying or associated with the disease to provide either a cure or relief from the disease symptoms.","For example, if one were to consider various options available for treating pain symptoms, the possible diagnoses, medicaments and therapies are many; similarly there are several options available for accelerating fractured bone healing.","It is possible that the therapy/medication a patient receives could be subjective and depend upon the particular doctor/physician, i.e., his/her background, expertise and past experiences.","For example, a physiotherapist or an orthopedic physician may treat a pain symptom differently than a physician or pain management specialist.","Although a doctor plays a critical role in diagnosing and prescribing the therapy, the patient (and his/her family members or care givers) also has great responsibility in complying with the prescription, and following the course of action for achieving improved health and better quality of life.","However, unfortunately, depending upon the patient demographics and nature of the disease, health care management of pain management and implementation of pain management has become a daunting task and an expensive affair.","For example, of the all diseases, chronic pain is one of the most underestimated health care problems in the world today, causing major consequences for the quality of life of the patients and the family members and has been a major burden on the health care system.","The most common causes of chronic pain are musculoskeletal problems (fractures, dislocations, soft injuries) and inflammatory conditions, with back pain and arthritis pain symptoms accounting for a significant portion of the overall chronic pain population.","The four most common ways to treat pain are: (1) pharmaceutical (e.g., analgesics, aspirin; NSAIDs, Ibuprofen, COX-2 inhibitors, celecoxib; opioids, morphine), (2) procedural (neuro-stimulators, pulsed radiofrequency, intrathecal), (3) psychological (behavioral, cognitive), and (4) physical (e.g., heat, cold, transcutaneous electric nerve simulation (TENS), therapeutic ultrasound, infrared, microwave or shortwave diathermy, electro-magnetic radiation, acupuncture, massage Although pharmaceutical methods (e.g., drugs) are most widely used for treating pain, individuals on over the counter or prescription drugs for pain are frequently dissatisfied with the results of the pharmaceutical treatment.","Further, the adverse side effects that drugs may cause on prolonged usage is shifting the focus away from drugs toward alternate methods for managing chronic pain.","The procedural methods are invasive, expensive and their effectiveness has been difficult to quantify.","Psychological therapies often lack practicality and their success rates have been limited.","Finally, physiotherapy based methods have been proven attractive, but they are inconvenient, require bulky/complex instruments, and regular office/hospital visits, all of which lowers compliance.","In addition, these therapies are often not supported by quality clinical data despite tremendous advances made in understanding pathophysiology and pain signaling.","Although, a number of physical medicine/modalities based therapies have been administered to treat musculoskeletal pain, identifying the optimal therapy and dosage for pain symptoms has been elusive.","For example, clinical data published in the literature indicates that the application of physical medicine is appropriate/beneficial in some cases and not particularly beneficial in other cases.","The response from patients to these methods is similarly mixed.","Given this background, the patient (or his/her doctor) has no way of knowing what is the best treatment method.","If one were to consider the combined use of these the application of physical therapies, the possible variations may be several (including dosage, therapy session and duration), but combination therapies may provide an opportunity to fine tune the therapy in order to make it efficacious or even personalized, especially when one takes advantage of modern technological advances such as computing, internet of things, sensing, connectivity, big data, and analytics in conjunction with electronic medication/therapy or remote administering/dispensing of medicines electronically.","Therefore, there exists a need for a medical device and an associated system for offering improved therapies for sustained pain relief that takes into account objective and subjective patient feedback and further takes into account the statistical certainty of obtaining a satisfactory outcome.","Another healthcare industry that can benefit from improved treatments relates to healing of fractured bones.","Over 50 million bone fractures occur worldwide, leading to about 10 million doctor or emergency room visits per year in the United States alone.","Delayed bone healing can result in increased pain, as well as loss of function and decreased quality of life.","Current therapies or treatment approaches for healing fractured bones include delivering bone morphogenetic proteins (“BMPs”), platelet-rich plasma (PRP), or anabolic agents such as teriparatide (“TPD”).","These treatments can be invasive and are not always successful.","Other proposed solutions have been to implement bone growth stimulation devices.","Such devices deliver low intensity pulsed ultrasound (“LIPUS”), which is believed to result in faster bone healing, but requires personalization of therapy dosage, that is, normalization of therapy dosage for a given composition (fat and muscle) and thickness of tissue surrounding a fractured bone.","However, the existing therapies do not offer personalized solutions.","For example, delivering a certain amount of ultrasound to one patient having one body composition will not achieve the same result as delivering that same amount of ultrasound to a different patient having a different body composition, or for that matter, different body parts of an individual contain different tissue thicknesses and compositions.","Ultrasound penetration into deep tissue is limited by tissue thickness and composition.","An identical dosage of low intensity pulsed ultrasound (LIPUS) may deliver inconsistent or suboptimal dosages to different patients.","Accordingly, the present inventors have determined that the personalized pain management therapies described herein may also be useful in order to promote faster healing of fractured bones or other tissues.","They have combined the personalized temperature therapy/ultrasound therapy/electrical stimulation therapy that may be delivered by the disclosed device in order to offer improved therapies for faster bone healing.","Typically, the attenuation coefficient, loss of ultrasound energy due to absorption, scattering, and mode conversion, decreases as temperature of tissue raise from 0 to 50° C.

portable, electronic therapy device that is capable of delivering thermal energies, electrical energies, ultrasonic energies, and various combinations thereof in order to promote various therapeutic purposes.","In a particular embodiment, delivery of these energies, either alone or in various combinations, has been found to be useful in improving bone healing processes.","The therapy device can include automatic controlled application of energies along with feedback control using sensors for improved synergistic effects and dose titration.","The device can be used for pain management, bone healing, tissue healing, fitness, cosmetic and topical delivery, and other related applications.","The methods and systems provide improved uses for devices configured to deliver pain management or bone or other tissue healing therapies.","BACKGROUND An individual with a disease, particularly a chronic disease or any ailment that takes more than one or two months to heal, may be required to monitor various health parameters on a regular basis in support of any treatment or therapy that he or she is undergoing or receiving.","Today, advances in medical research enable a range of therapeutic options to treat a given disease, or ailment and/or their symptoms, where each of the proposed therapies targets a particular biochemical or physiochemical process underlying or associated with the disease to provide either a cure or relief from the disease symptoms.","For example, if one were to consider various options available for treating pain symptoms, the possible diagnoses, medicaments and therapies are many; similarly there are several options available for accelerating fractured bone healing.","It is possible that the therapy/medication a patient receives could be subjective and depend upon the particular doctor/physician, i.e., his/her background, expertise and past experiences.","For example, a physiotherapist or an orthopedic physician may treat a pain symptom differently than a physician or pain management specialist.","Although a doctor plays a critical role in diagnosing and prescribing the therapy, the patient (and his/her family members or care givers) also has great responsibility in complying with the prescription, and following the course of action for achieving improved health and better quality of life.","However, unfortunately, depending upon the patient demographics and nature of the disease, health care management of pain management and implementation of pain management has become a daunting task and an expensive affair.","For example, of the all diseases, chronic pain is one of the most underestimated health care problems in the world today, causing major consequences for the quality of life of the patients and the family members and has been a major burden on the health care system.","The most common causes of chronic pain are musculoskeletal problems (fractures, dislocations, soft injuries) and inflammatory conditions, with back pain and arthritis pain symptoms accounting for a significant portion of the overall chronic pain population.","The four most common ways to treat pain are: (1) pharmaceutical (e.g., analgesics, aspirin; NSAIDs, Ibuprofen, COX-2 inhibitors, celecoxib; opioids, morphine), (2) procedural (neuro-stimulators, pulsed radiofrequency, intrathecal), (3) psychological (behavioral, cognitive), and (4) physical (e.g., heat, cold, transcutaneous electric nerve simulation (TENS), therapeutic ultrasound, infrared, microwave or shortwave diathermy, electro-magnetic radiation, acupuncture, massage Although pharmaceutical methods (e.g., drugs) are most widely used for treating pain, individuals on over the counter or prescription drugs for pain are frequently dissatisfied with the results of the pharmaceutical treatment.","Further, the adverse side effects that drugs may cause on prolonged usage is shifting the focus away from drugs toward alternate methods for managing chronic pain.","The procedural methods are invasive, expensive and their effectiveness has been difficult to quantify.","Psychological therapies often lack practicality and their success rates have been limited.","Finally, physiotherapy based methods have been proven attractive, but they are inconvenient, require bulky/complex instruments, and regular office/hospital visits, all of which lowers compliance.","In addition, these therapies are often not supported by quality clinical data despite tremendous advances made in understanding pathophysiology and pain signaling.","Although, a number of physical medicine/modalities based therapies have been administered to treat musculoskeletal pain, identifying the optimal therapy and dosage for pain symptoms has been elusive.","For example, clinical data published in the literature indicates that the application of physical medicine is appropriate/beneficial in some cases and not particularly beneficial in other cases.","The response from patients to these methods is similarly mixed.","Given this background, the patient (or his/her doctor) has no way of knowing what is the best treatment method.","If one were to consider the combined use of these the application of physical therapies, the possible variations may be several (including dosage, therapy session and duration), but combination therapies may provide an opportunity to fine tune the therapy in order to make it efficacious or even personalized, especially when one takes advantage of modern technological advances such as computing, internet of things, sensing, connectivity, big data, and analytics in conjunction with electronic medication/therapy or remote administering/dispensing of medicines electronically.","Therefore, there exists a need for a medical device and an associated system for offering improved therapies for sustained pain relief that takes into account objective and subjective patient feedback and further takes into account the statistical certainty of obtaining a satisfactory outcome.","Another healthcare industry that can benefit from improved treatments relates to healing of fractured bones.","Over 50 million bone fractures occur worldwide, leading to about 10 million doctor or emergency room visits per year in the United States alone.","Delayed bone healing can result in increased pain, as well as loss of function and decreased quality of life.","Current therapies or treatment approaches for healing fractured bones include delivering bone morphogenetic proteins (“BMPs”), platelet-rich plasma (PRP), or anabolic agents such as teriparatide (“TPD”).","These treatments can be invasive and are not always successful.","Other proposed solutions have been to implement bone growth stimulation devices.","Such devices deliver low intensity pulsed ultrasound (“LIPUS”), which is believed to result in faster bone healing, but requires personalization of therapy dosage, that is, normalization of therapy dosage for a given composition (fat and muscle) and thickness of tissue surrounding a fractured bone.","However, the existing therapies do not offer personalized solutions.","For example, delivering a certain amount of ultrasound to one patient having one body composition will not achieve the same result as delivering that same amount of ultrasound to a different patient having a different body composition, or for that matter, different body parts of an individual contain different tissue thicknesses and compositions.","Ultrasound penetration into deep tissue is limited by tissue thickness and composition.","An identical dosage of low intensity pulsed ultrasound (LIPUS) may deliver inconsistent or suboptimal dosages to different patients.","Accordingly, the present inventors have determined that the personalized pain management therapies described herein may also be useful in order to promote faster healing of fractured bones or other tissues.","They have combined the personalized temperature therapy/ultrasound therapy/electrical stimulation therapy that may be delivered by the disclosed device in order to offer improved therapies for faster bone healing.","Typically, the attenuation coefficient, loss of ultrasound energy due to absorption, scattering, and mode conversion, decreases as temperature of tissue raise from 0 to 50° C. Penetration of low intensity pulsed ultrasound through deep tissue to heal fractured bones varies depending tissue temperature.","In theory, one can take advantage of this phenomena by preconditioning tissue temperature during LIPUS therapy to maximize therapeutic benefits.","Use of the disclosed device has been found to provide controls for enabling deeper penetration of low intensity ultrasound or modulating ultrasound energy profile delivered to the injure tissue/bone areas, while personalizing the delivered therapy using sensors (that measure tissue thickness, rate of bone healing, blood

benefit for encouraging faster bone healing.","Although the present disclosure will relate to and use the term “pain management” therapies and devices, it should be understood that the same pain management therapies and devices described may also be used in order to encourage the bone healing process described herein.","Systems and methods are also disclosed for computer-implemented pain management or bone healing through the use of a device that applies a combination of physical therapies to alleviate pain symptoms and/or to encourage faster bone healing, and it adjusts the application of the physical therapies based on feedback information.","Feedback information includes physiological responses resulting from the applied therapy, patient feedback received as a pain relief score (e.g., a score from 0-10 or 0-5 as the case may be), and analytics information indicating the personalized therapy for patients with similar demographics/pre-existing medical conditions and other characteristics as the current patient.","The therapy includes application of physical therapies via an applicator.","Physical therapies include electroceuticals (i.e., any type electrical stimulation used for therapeutic benefit), thermoceuticals (e.g., defined as a thermal or heat therapy method or device designed to affect biological systems and modify function(s) of the body, and/or ultrasound therapies (i.e., any system that can deliver ultrasound waves such as low intensity pulsed ultrasound (LIPUS) to the patient), or any combination thereof.","As part of thermal therapy, thermal energy is delivered to the body or superficial or deep tissue using a variety of devices and methods known to those skilled in the art.","The temperatures applied to the body locally or systemically and may vary from about−100° C. to+about 100° C.).","In other examples, the temperature may range from 0-50° C. Any combination of these treatments may be combined, depending upon the patient and the condition to be treated.","One exemplary device for managing pain is described in U.S. Pat.","No.","9,710,607, titled “Portable Electronic Therapy Device and the Method Thereof,” which is incorporated by reference herein.","The physical therapies applied via the computer-implemented therapy target specific physiological functions (i.e., without using any drugs) of the tissue through external non-invasive stimulation (or invasive stimulation) to provide pain relief and/or bone healing.","A variety of physiological functions can be influenced, simply by changing the temperature of the tissue (e.g., cold, or heat at superficial or deeper levels) using a variety of methods such as cold or hot packs/baths, infrared lamps, lasers, shortwave diathermy, microwave diathermy, therapeutic ultrasound, and radio frequency application.","Some of the physical medicine-induced changes include variations in cell membrane, or protein or nucleic acid structure and function, enzymatic activity, cell apoptosis, nerve conduction, coagulation, collagen fiber contraction, collagen synthesis, vasodilation, vasoconstriction, viscosity of body fluids/blood, cellular fluid crystallization or dehydration, pain signaling, production of endorphins, spasm, tissue metabolism, blood flow, inflammation, edema extensibility, supply of oxygen & nutrients, tissue/muscle repair or healing, fibroblast activity, collagen fibril density, protein synthesis, and tissue regeneration.","Some of the physical parameters that alter based on tissue temperature include the propagation profiles of energy waves, such as ultrasound velocity and attenuation as a function of tissue temperature, depth, and composition.","Some of the physical medicine based therapeutic indications include pain (chronic or acute) relief, musculoskeletal pain relief, sports injuries, post surgical pain, post surgical edema, reduction in inflammation, reduction of joint contractures, fibromyalgia, migraine, tissue healing, swelling reduction, Hematoma resolution, acute bone healing, wound healing, face lift, wrinkle reduction, angiogenesis, removal of warts, cancer therapy, strains, contracture, decrease in muscle spasticity, tumors, capsulitis, bursitis, myositis, tendonitis, improving range of motion, rheumatoid arthritis and osteoarthritis.","Application of thermoceuticals or thermal therapy includes both heat therapy and cold therapy.","Heat therapy can ease pain by increasing blood flow to affected areas, which can help decrease inflammation, relax tight muscles and eliminate waste products such as lactic acid that cause stiffness and soreness.","Likewise, application of cold may facilitate healing after injuries and limits musculoskeletal pain.","Cold therapy induces a drop in skin temperature and a modest decline in temperatures within the muscles and joints, thereby causes arteriolar and capillary vasoconstriction in the skin leading to decrease in local synovial blood flow to reduce swelling.","Further, the propagation speeds of ultrasound waves increase as the tissue temperature raises up to 50° C., while the attenuation coefficient (loss of energy due to absorption and scattering) decreases.","Thermoceuticals can be applied via any suitable mechanism for changing the temperature of the tissue.","For example, thermoceuticals can be applied via surface heating/cooling using heat pack or cold packs or by microwave radiation, shortwave radiation, ultrasound application, infrared radiation.","In some examples, the applicator described herein is configured to deliver thermoceutical energy to the body continuously or in a pulsed mode, or combinations thereof.","The thermal energy delivered may be in temperature range of from about 0-60° C. In a specific example, the device can deliver thermal energy at about 42° C. Application of ultrasound therapies stimulates tissue beneath the skin's surface using sound waves.","Exemplary ranges include from about 0.1 MHz to about 10 MHz.","Other specific ranges may include from about 0.5-3.0 MHz (with tolerances including±20%) A specific low intensity pulsed ultrasound frequency may be about 1.5 MHz.","In some examples, the ultrasound may be pulsed.","In some examples, the ultrasound may be pulsed while the tissue temperature is altered between 0 to 50° C. In some examples, the ultrasound may be delivered continuously.","In further examples, the ultrasound may vacillate between continuous delivery and pulsed delivery.","The ultrasound frequency range delivered may depend upon set parameters, for example, may be based upon the patient's tissue composition.","The intensity of the ultrasound may range from about 0.005 W/cm2 to about 3.0 W/ cm2.In some examples, ultrasound can cause a temperature rise up to 10° C. in 2-8 cm deep tissue or at least up to 5° C. The ultrasound can also imparts non-thermal effects such as acoustic streaming and cavitation to provide pain relief.","Thermal changes also result in activation of a wide variety of thermal receptors (transient receptor potential channels (TRP)) in the skin/tissue that range from 0-60° C. and may mask pain signals to the brain.","Activation of these receptors either chemically (e.g., menthol activates TRPA1, TRPM8, while capsaicin activates TRPV1, TRPV3) or physically can lead to masking of the pain sensation.","In some embodiments of the present disclosure, the pain signal to the brain is masked by providing a method/mechanism to maximize/overwhelm the signal(s) from an individual or multiple TRP channels located around painful musculoskeletal region.","The distribution ratio of various temperature sensitive receptors in the body varies depending upon the body location.","For example, upper part of the body comprises more heat temperature receptors than cold temperature receptors.","The present inventors believe that pulsing low intensity ultrasound while controlling the tissue temperature help minimize the losses of ultrasound energy due to attenuation and increases ultrasound velocities inside the tissue, and thereby encourages more effective and efficient bone healing.","Preheating or Pre-cooling or Pre-conditioning of the tissue around injured area (that is injured bone or tissue) can help encourage greater penetration of the ultrasound.","Without wishing to be bound to any theory, it is believed that raising the patient's tissue temperature to about 50° C., while also delivering ultrasound waves (pulsed or continuous), can help reach the underlying bone tissue more effectively (i.e., with higher velocities and low attenuation coefficients).","It is believed that this treatment may help improve bone healing by up to about 30 to 40% or even more.","However, not all patients have the same tissue composition.","Some patients may present with more fat tissue, others with more muscle tissue, and different densities of tissue or body mass indices will require different dosages for treatment to ensure the right dosage of ultrasound energy is experienced by the injured bones/tissue therapy point.","Ultrasound waves are absorbed more as they extend deeper into tissue.","The ultrasound intensity that reaches the bone will vary based on the delivered parameters such as ultrasound frequency, intensity, pulsing profile, tissue temperature, tissue thickness/composition in a therapeutic area.","Embodiments disclosed herein also include computer-implemented therapy that applies electroceuticals as electrical stimulation of nerves.","In electric stimulation, electrical current at distinct voltages, frequencies and intensities is delivered to the skin through electrodes (e.g., TENS, electric muscle stimulation, EMS, or neuromuscular electric stimulation, LAMES, IFT, inferential therapy).","Pain is relieved by means of the pain gate mechanism involving activation of sensory fibers that mask the pain and/or suppressing of pain signals to the brain.","It is also believed possible that delivery of electric stimulation may help healing of fractured bones, the bone healing may be accelerated in conjunction with low intensity pulsed ultrasound while keeping the tissue temperature at native body temperature or by externally altering it with the aid of thermoceuticals.","Additionally, electrical stimulation can generate a physiological response to the irritation produced by electrical stimuli which leads to the release of endorphins.","Electrically pulsed stimulation also causes enhanced localized muscle activity and thereby increases blood circulation to remove metabolic toxins, thereby reducing pain symptoms and/or may encourage bone growth.","The electroceuticals can be applied to the body using either low (1-20 Hz) or high frequencies (20-200 Hz) for treating pain and several other therapeutic indications.","In other words, the energy delivered may range from about 2-200 Hz, or any range there between.","The voltages used for electric stimulation may vary from 3 V to 120V, while the wave forms applied could assume different shapes such as square, asymmetrical biphasic, and symmetrical biphasic.","In other examples, the range may be from 10 V to 120V.","The stimulation could be applied to the body continuously or in pulsed mode or in burst mode to trigger different therapeutic mechanisms for treating ailments.","Although, the therapeutic mechanism behind electric stimulation has not yet been unequivocally established, it is generally believed that electric stimulation enables the body to produce its own endorphins, increases local blood flow and mask pain signals via pain gate mechanism and several other hypotheses as proposed in the literature.","It is believed that combining electrical stimulation, thermal therapy, and ultrasound together can offer efficient pain management options.","It is also believed that combining electrical stimulation, thermal and ultrasound therapies together can offer rapid healing of fractured bones.","For any of the treatments described, the delivery of the thermal therapy, ultrasound, and/or electrical stimulation or any combination thereof described may be pulsed.","The delivery of the heat therapy, ultrasound, and/or electrical stimulation or any combination thereof described may be continuous.","The delivery of the heat therapy, ultrasound, and/or electrical stimulation or any combination thereof described may be alternated.","The delivery of the heat therapy, ultrasound, and/or electrical stimulation or any combination thereof described may alternate between pulsed and/or continuous.","The particular therapy may be optimized for the patient.","If pulsed, it is possible for the time range of the pulsing to the separated by microseconds, milliseconds or seconds.","Typically, electric stimulation pulsing could be in the order of micro to milliseconds.","Acoustic pulsing could be in the order of milliseconds.","Thermal pulsing may be in the order of seconds to minutes.","In some embodiments, the therapy device may communicate with a physician computing device to provide personalized care via application of personalized pain management therapy through customized application of electroceuticals, and thermoceuticals.","For example, a physician computing device can receive inputs from a healthcare provider for setting the initial physical therapy and adjusting the therapy as the treatment is applied.","The initial pain management therapy may also be set via a patient computing device communicatively coupled to the pain therapy device.","The initial pain management therapy indicates the specific combination and intensity levels of electroceuticals, thermoceuticals, and/or ultrasound.","During treatment, sensors communicatively coupled to the pain management device detect the physiological responses resulting from the application of the pain management therapy.","The pain therapy device also receives patient feedback indicating pain relief scores via a user interface for the patient computing device (or entered directly from the graphic user interface of pain therapy device).","The pain therapy device continues to apply the physical therapies (e.g., the electroceuticals, thermoceuticals, ultrasound, acupuncture, pressure/massage based therapies) indicated in the therapy until the physiological responses/patient feedback indicates a threshold pain management level has been reached.","For example, as the pain management therapy is applied, the sensors coupled to the pain therapy device may detect an increase in blood flow or an increase in blood-oxygen levels at the localized area of pain.","If the rate of blood flow (or bone healing) and the value of the blood-oxygen levels reach a threshold value specified in the pain management treatment, the pain therapy device reduces or completes the application of the physical therapies.","Similarly, the pain therapy device may receive feedback from the patient via a user interface indicating the pain has decreased (e.g., by indicating a pain relief score on a 0-5 or a 0-10 scale).","In response, the pain therapy device continues or completes or modifies the application of the physical therapies.","For example, a therapy analysis engine executing on the pain therapy device receives updates from a physiological data collection engine and from a patient feedback interface and uses the collected information to iterate the dosage of the physical medicine.","Embodiments disclosed herein also recognize that the demographics of chronic pain patients (or patients with fractured bones) and the physical therapy requirements are unique.","It has been well documented in the literature that people with certain pain symptoms, do not respond to electroceuticals and thermoceuticals (or even pharmaceuticals) in similar fashion.","For example, some people may get pain relief using TENS, and others may not respond to such a therapy at all, and may even have allergic reaction.","Therefore, the physiology of individuals and the patient feedback plays an extremely important role in determining the ideal/optimal therapy.","In addition to being responsive to patient feedback and physiological response from an applied pain therapy, the pain therapy device further tailors or “titrates” physical medicine(s) dosage (energy type(s), intensity, exposure depth and duration) based on the patient demographics (e.g.","age, gender, body mass index, ethnicity, pre-existing health conditions and cultural background).","For example, the server system includes a patient analytics database that stores patient demographics and applied therapy information (e.g., the specific combination of the physical therapies applied and the dosage levels) as well as information on outcomes of the applied pain management therapy on multiple individuals that had previously applied pain management therapies.","The database may comprise enormous amount of information from hundreds or thousands or even millions of individual patients and provides a powerful tool to conduct data analytics (analogous to an automated virtual/crowd-sourced clinical study that constantly gets updated with addition of ever increasing data sets) and customize the pain therapy for individuals either in an automated fashion or through prompt response from the physician.","The analytics data can indicate the statistical likelihood of satisfactory pain management outcomes from application of the pain therapy.","The pain therapy device connects with the server system over a network to compare the patient information for a specific patient with the patient information in the analytics data to identify a subset of individuals that have similar characteristics as the patient.","For example, the therapy analysis engine may comprise a software application or software module executing in either the pain therapy device or the server system.","The therapy analysis engine identifies a subset of individuals that are with the same age range, gender, body mass index, and other pre-existing medical conditions, pain therapies received in the past or on-going (including drugs, or surgical procedures or alternate medicines), physical characteristics as the patient.","The therapy analysis engine also identifies one or more pain management therapies that were applied to the subset of individuals that resulted in favorable pain management outcome.","The pain therapy device can thus personalize the applied pain management therapy based on subjective data such as patient feedback, objective data such as physiological responses to the applied therapy, as well as analytics data that can indicate the personalized pain management therapy as collected from other patients with similar characteristics as the patient.","The pain therapy device can transfer the patient information and the pain management therapy information through wireless connectivity to the database for storage in the analytics system.","In this way, the pain management adds the current patient's information (e.g., demographic information, symptoms, etc.","), applied pain management therapy, and therapy outcomes (e.g., patient relief scores and physiological changes resulting from the therapy) to the analytics database.","These illustrative aspects and examples are given to introduce the reader to the general subject matter discussed here and are not intended to limit the scope of the disclosed concepts.","The following sections describe various additional features and examples with reference to the drawings in which like numerals indicate like elements, and directional descriptions may be used to describe the illustrative aspects but, like the illustrative aspects, should not be used to limit the present disclosure.","FIG.","1 is a block diagram depicting a pain therapy device 100 that connects to a server system 130 over a network 115 to provide personalized pain management therapies based on measured physiological/sensor feedback data (including blood flow and musculoskeletal characterization related data), subjective patient input data (e.g., a pain relief score), and analytics data compiled on other patients and applied pain therapies.","The pain therapy device 100 can be communicatively coupled to a patient computing device 120 and/or a physician computing device 110 for receiving feedback to adjust the applied pain management therapy.","The pain therapy device 100 includes a memory 101 that stores executable program code for

computing device 110 can prescribe the personalized pain management therapy via the physician interface application 112.For example, the physician interface application 112 presents a user interface for selecting a physical medicine via a combination of electroceuticals, or thermoceuticals.","In other embodiments, the patient computing device 120 includes a patient interface application 122 for inputting patient information.","Via the patient interface application 122, the patient provides inputs regarding the personalized pain management therapy as discussed or otherwise prescribed by the healthcare provider.","The personalized pain management therapy can thus be administered via the health care provider or self-administered via the patient.","One or more applicators 124 connected to the pain therapy device 100 apply the personalized pain management therapy input via physician interface application 112 or patient interface application 122 or directly through physical therapy device 100.The personalized pain management therapy comprises of physical therapies that include a combination of electrical stimulation, hot and cold stimulation, and ultrasonic pulses.","In some embodiments, based on feedback received from physician computing device 110 and patient computing device 120, the therapy analysis engine 104 executing on the pain therapy device 100 adjusts the applied personalized pain therapy accordingly.","For example, inputs received via a patient feedback interface 111 presented on physician computing device 110 or patient feedback interface 121 presented on patient computing device 120 may indicate a pain relief score from a value of 0-10, with 10 indicating the most intense pain and 0 indicating no pain.","It should be understood that other values or indications could be used, such as emoticons, descriptive text, color, or a selection on a continuum.","As the personalized pain management therapy is applied via applicator 124, a pain relief score may be received indicating a low measurement of pain.","A satisfactory application of personalized pain management therapy can be based, for example, on reduction of a pain relief score by a certain pre-programmed threshold.","In response, the therapy analysis engine 104 may adjust the personalized pain management therapy by adjusting the dosages and intensities of physical therapies to accommodate for lesser pain.","The feedback comprising the pain relief score may also be received directly on a user interface on pain therapy device 100.For example, memory 101 of patient therapy device 100 may include program code for executing a patient feedback interface 107 used to receive feedback to the therapy from the patient.","In further embodiments, the therapy analysis engine 104 adjusts the personalized pain therapy in response to physiological measurements detected via one or more sensors coupled to pain therapy device 100.For example, a physiological data collection engine 102 executing in memory 101 of pain therapy device 100 may receive information on the blood-oxygen levels, rate of blood flow, and tissue thickness from connected sensors.","The personalized pain management therapy may include instructions on applying physical therapies at specific dosage levels and adjust the applied physical therapies in response to changes in physiological measurements.","For example, the therapy analysis engine 104 may apply a combination of electrical stimulation at a certain intensity level, heat stimulation at a certain temperature, and ultrasonic pulses until a physiological responses indicate a blood flow of a certain rate.","Once the specified blood flow rate (or blood oxygen levels) is achieved, pain therapy device 100 may apply physical therapies with different intensity levels/temperature values.","This process continues until the pain management therapy is complete (e.g., the prescribed physical therapies are fully administered).","In additional embodiments, patient symptoms and demographic information on the patient (i.e.","user of pain therapy device 100) may be compared with analytics information stored on multiple other patients to determine the personalized pain management therapy.","The analytics data is stored on a patient analytics database 132 in server system 130 and comprises patient information compiled on numerous other patients.","For example, the stored patient information includes data on prior patient demographics, prior patient pain symptoms, the pain management therapies previously applied on the other patients, and the outcomes of the pain management therapies (e.g., indicating satisfactory outcome, unsatisfactory outcome, etc.).","The analytics data can also include the average pain feedback score that was indicated by the prior patients in response to previously applied pain management therapies.","In one embodiment, a server system interface engine 106 is a software application or module executing in pain therapy device 100.The server interface engine 106 transmits data comprising the patient information to server system 130.The server system interface engine 106 provides instructions for communicating the patient information to server system 130 and receiving information in response from server system 130.Based on the received patient information, a therapy analysis engine 131 executing on the server system 130 identifies a subset of individuals that have similar characteristics as the user of pain therapy device 100.For example, therapy analysis engine 131 may identify a subset of individuals that are in the same age range, have the same gender, have a similar body mass index as the user of pain therapy device 100, and/or have similar pain symptoms, or any combination thereof.","The therapy analysis engine 131 may also identify a prior applied pain therapy among the subset of individuals that is associated with a pain therapy outcome indicating reduced pain symptoms.","For example, the therapy analysis engine 131 may identify a prior applied pain therapy among the subset of individuals that indicates a satisfactory pain management outcome.","A pain therapy with a satisfactory pain management outcome may include pain therapies that have resulted in reduced pain relief scores by a certain threshold (e.g., 2 points or more).","A pain therapy with a satisfactory pain management outcome may also be indicated when a health care provider has approved a given therapy or removed a patient who has had a successful result with the therapy.","A pain therapy with a satisfactory pain management outcome may also be indicated by accomplishment of objective physiological measurements such as reduction in inflammation or improvement in range of motion, improvement in local blood oxygen levels or flushing out toxins in the injured body part or visually observation of parameters such as wound healing or bone healing or any measurable parameters that either directly or indirectly correlate with reduction in pain as deemed appropriate by physician.","The selected pain management therapy based on the analytics data is transmitted to the pain therapy device 100.Because the received pain management therapy is determined from prior therapies applied on patients with similar characteristics to user of pain therapy device 100, the received pain management therapy is personalized to the user of pain therapy device 100.In another embodiment, the pain therapy device receives the analytics data on other patients from the server system 130.The therapy analysis engine 104 executing in pain therapy device 100 uses the received analytics data to select the subset of individuals that have similar characteristics as the user of pain therapy device 100.In this embodiment, the therapy analysis engine 104 identifies a personalized pain management therapy that, from the analytics data, indicates prior satisfactory outcome (e.g., reduction in pain symptoms).","The analytics data is depicted as stored in patient analytics database 132 in server system 130 for illustrative purposes.","In other embodiments pain therapy device 100 stores the analytics data.","FIG.","2 depicts a block diagram illustrating the logical components of pain therapy device 100.Pain therapy device 100 includes a micro-controller unit (MCU) 210.MCU 210 includes processing devices such as an application specific integrated circuit (ASIC), or any general-purpose processor.","MCU 210 can include logic for connecting to external

surface contact sensor 238 (for detecting if the applicator 124 is in contact with tissue.","In some embodiments, sensors 230-238 can be included as part of applicator 124 (as shown further below in FIG.","3).","The MCU can also include or be in communication with a computer-readable medium storing instructions that, when executed by the MCU 210, cause the MCU 210 to perform the operations described herein.","For example, the MCU 210 is in communication with memory 101, which includes any suitable non-transitory computer-readable medium.","The computer-readable medium includes any electronic, optical, magnetic, or other storage device capable of providing a processor with computer-readable instructions or other program code.","Non-limiting examples of a computer-readable medium include a magnetic disk, memory chip, ROM, RAM, an ASIC, a configured processor, optical storage, magnetic tape or other magnetic storage, or any other medium from which a computer processor can read

characteristics of the pain management therapy as applied by applicator 124.Control inputs 222-234 include a heat switch 222, cold switch 224, ultrasound switch 226, ultrasound intensity control 228, ultrasound duty cycle 230, electric stimulation switch 232, and infrared switch 234.Ultrasound switch 226, ultrasound intensity control 228, and ultrasound duty cycle control 230 (which control the respective characteristics of the ultrasound pulses that are part of the pain management therapy) are fed to ultrasound power amplifier 236.Ultrasound power amplifier 236 provides necessary amplification of the signals before driving the ultrasound output of applicator 124.The output from electric stimulation switch 232 can be fed to electric stimulation circuit 238 before driving the electrical characteristics of applicator 124.Similarly, output from infrared switch 234 can be fed to infrared circuit 240 before driving infrared output of applicator 124.Via heat switch 222 and cold switch 224, temperature characteristics of applicator 124 can be specified.","The output of heat switch 222 and cold switch 224 for controlling the temperature characteristics are provided to applicator 124.In some embodiments, the control inputs 222-234 can be coupled to MCU 210 via an I2C expander port 220.A medical grade power supply 202 can provide the power requirements to the components herein.","For example, medical grade power supply 202 provides power to ultrasound power amplifier 236, applicator 124, electric stimulation circuit 238, and infrared circuit 240.FIG.","3 illustrates a representation of the various components present in the applicator 124, as shown as different layers.","The sequencing of the various layers could be altered and does not necessarily have to be in the order shown in FIG.","2.Further, multiple layers/components of the applicator 124 could be embedded into a single layer or form physically distinct layers.","The control inputs 222-234 provide the electrical signals that control the various layers of applicator 124.The layers for applicator 124 can be placed on the surface area of the tissue of the patient for whom the pain management therapy is applied.","Applicator 124 can include a heat sink component 302, which measures the temperature of the tissue on which the applicator 124 is applied.","The thermoelectric element component 304 applies the hot or cold temperature as specified by heat switch 222, cold switch 224, and the specific temperature as set by MCU 210.The applicator 124 can also include a PCB & LED component 306 that can display.","The PCB inside the applicator integrates the thermoelectric elements, sensors, ultrasonic transducer and TENS electrodes and simplifies the connectivity.","The PCB is also capable of connecting to any additional sensors or thermal energy generating transducers integrated into the applicator (e.g., blood flow detection sensor, infra-red radiation source etc.).","The LED component visually indicates the status of applicator such as ON or OFF (especially, for the convenience of care providers).","In some embodiments, the applicator 124 can also include built in sensors 308, which include one or more of the temperature sensor 230, blood flow sensor 232, oxygen sensor 234, tissue thickness sensor 236, and applicator surface contact sensor 238.Some of the

sensors 308 could gather a variety of medically useful/diagnostic data related to treating pain, healing fracture bones, and may help monitoring the progress of healing or administering right dosage for a given therapy as defined.","The ultrasound transducer 312 can be utilized by the therapy analysis engine 104 to identify the thickness or depth of the tissue based on ultrasound reflection intensity measured.","This kind of sensing feature helps provide for the inclusion of safety features regarding the device usage on different parts of the body (e.g., it is possible to prevent the usage of the device on the head or skull of the patient).","The sensing feature also enables the determination of physical dosage to be delivered to a targeted area.","FIG.","4 is a flowchart depicting an example process 400 for applying a personalized pain management therapy based on stored analytics data on numerous other prior patients and adjusting the applied therapy based on physiological feedback.","This is conceptually similar to a flow chart that could be used for rapid/personalized healing of fractured bones.","The process 400 may be performed by one or more of the components listed in FIGS.","1-3 or in any suitable computing and/or communication environment.","The process 400 involves receiving patient information specifying patient demographic data, patient physiological data, and patient pain symptoms, as shown in block 410.Demographic data can include information on patient such as age, gender, body weight and BMI, race, and geographic information.","Patient pain symptoms include descriptions of patient pain symptoms and indications of pain.","For example, patient pain symptoms can include a graphical indication of a body part (e.g., by selection of an area of a body on a touch screen) to show areas of localized pain, textual descriptions of the areas of localized pain, and a numeric pain relief score indicating the severity of the pain at the specified location.","Pain symptoms can also be more or less detailed.","All common chronic pains and musculoskeletal pains such as back pain, neck pain, shoulder pain, arthritis, muscle spasms, tendonitis, bursitis, sports injuries are either visually or verbally represented.","Any other form of pain that requires diagnosis by qualified physician (e.g., fibromyalgia) or that cannot be treated using pain therapy device (visceral pain, especially involving cutting, burning and/or involving internal organ damage) will not be included in the system as a default.","Patient physiological data includes physiological measurements of a measured tissue area.","Physiological measurements include, for example, the measured rate of blood flow, blood-oxygen levels, tissue depth, tissue composition, tissue temperature, bone strength, callus stiffness, acoustic emissions/reflections from fractured/partially healed/fully healed or normal/healthy bones, ultrasound velocity and attenuation across a healing fractured bone and other measurements.","The patient information may be received via inputs in physician interface application 112 in physician computing device 110 or patient interface application 122 in patient computing device 120 and transmitted to pain therapy device 100.In other embodiments, the patient information can be directly entered in pain therapy device 100 via a user interface on the pain therapy device 100.While the pain therapy device 100 can process the patient information to determine the personalized pain management therapy, in other embodiments, the patient information is transmitted to server system 130.Process 400 also includes comparing the received patient information with pain analytics data compiled on a plurality of individuals to determine a recommended pain management therapy, as shown in block 420.For example, the server system 130 includes a patient analytics database 132 that stores the pain analytics data on numerous prior patients.","The pain therapy device 100 can transmit the patient information to the server system 130 for the comparison.","In other embodiments, the pain therapy device 100 can receive the analytics data from the server system 130 via network 115 for the comparison.","Therapy analysis engine 104 (executing in pain therapy device 100) or therapy analysis engine 131 (executing in server system 130) compares patient information with the pain analytics data to determine a subset of individuals with similar characteristics as the patient as explained above with respect to FIG.","1.Additionally, therapy analysis engine 104 or therapy analysis engine 131 identifies the recommended pain management therapy that previously depicted a satisfactory outcome (e.g., by lower received pain relief scores from other patients, from objective measurements of physiological data indicating lesser pain symptoms).","As shown in block 430, the recommended pain management therapy is applied via an applicator device 124.For example, the applicator device 124 provides one or more electroceuticals, or thermoceuticals, or ultrasound, or any combination at a specific frequency, intensity, and/or duration as specified by the recommended pain management therapy.","Note in some aspects, the recommended pain management therapy can be overridden and manually input via inputs received from physician computing device 110 or patient computing device 120.After application of the recommended pain management therapy (which is initially based on the analytics data on pain management therapies applied on other patients), the pain therapy device 100 can further adjust and personalize the therapy based on feedback from the patient.","As shown in block 440, process 400 further involves receiving, from one or more sensors, updated physiological data reflecting changes in the patient physiological data, and subjective patient feedback (in the form of pain score) in response to the applied recommended pain management therapy.","For example, as the recommended pain management therapy is applied by applicator 124, sensors 230-238 measure changes in the temperature, blood flow rate, blood-oxygen levels, and tissue thickness resulting from the therapy.","The sensor data can be received via a physiological data collection engine 102.The changes in the physiological data in response to the applied pain management therapy can be considered objective feedback to the pain management therapy.","Note that while the type of feedback in response to the applied pain management therapy described in block 440 is feedback from physiological data, other types of feedback are also possible.","For example, the pain therapy device 100 can receive subjective feedback from the patient in the form of a patient relief score (e.g., a numeric value from 0-10) as discussed above with respect to FIG.","1.The therapy analysis engine 104 can adjust the applied pain management therapy (or bone healing therapy) in response to the changes in physiological data (or in response to other feedback), as shown in block 450.For example, the applied voltage or current of the electrical stimulation, the temperature of the heating element, or the intensity of the ultrasonic pulses can be adjusted based on the changes in the physiological data or sensor data or based on patient feedback.","Probably, the pain relief scores from patients in conjunction with objective physiological data (whenever available) could be used to adjust or titrate the dosage of the physical medicine involving single or combination of therapies.","For example, the thermoceutical dosage may be defined by three parameters, i.e., intensity (e.g., temperature range; frequency, intensity and duty cycle in case of ultrasound), energy exposure time, and course duration for a given tissue thickness or composition (or BMI).","If the physical medicine dosage delivered does not increase the tissue temperature or raise the deep tissue temperature in stipulated time frame and/or for sustained time period, and/or do not provide pain relief to the patient, one could consider the dosage delivered is sub optimal.","At present, our understanding about how distinct physical modalities or their combination therapies at what dosage levels provide efficient pain relief is relatively limited.","Further complexity stems from the fact that pain is a subjective personal experience, and the physiology of individual is different from each other and the way each individual responds to given therapy is unknown.","If a patient does not respond to a particular electroceutical or thermoceutical pain therapy, it is not generally implied that the given therapy does not work; it only implies that given therapy is not appropriate for that patient.","Therefore, it is important to identify the patterns from various therapies provided to patients with diverse backgrounds and profiles to develop a personalized pain therapy.","Typically, the dosage delivered will always be within the safety limitations as outlined by data published in the literature, the dosages will be titrated based on positive response from patients (i.e., lower pain scores).","Once adequate data is accumulated from patient responses, it is possible to correlate pain relief (or rate of bone healing) measured in response to given physical medicine dosage with quantifiable physiological data or body reflex related measurements (e.g., increase local blood flow of injured body part, thermal imaging, tissue temperatures, blood oxygen levels, sensitivity to pressure etc.)","and constitutes one of the inventive aspect of this innovation.","As shown in block 460, the therapy analysis engine 104 makes a determination as to whether the updated physiological data indicates reduced pain symptoms (or faster bone healing).","For example, the physiological changes in treated body part may include vasodilation, vasoconstriction as quantified by blood flow volume or velocity or by variation in blood oxygen levels or simply by measurement of tissue temperature or measurement of pressure sensitivity to pain (using algometer) or it could even include identification/measurement of certain cellular or molecular changes or electrical signals caused in response to external stimulation.","If the updated physiological data or patient feedback indicates reduced pain symptoms (it is possible that subjective and objective evaluation results may not converge, the patient feedback coupled with statistics may precede physiological measurements), the patient information, patient feedback, the updated physiological data, the recommended pain management therapy, and the adjusted pain management therapy are stored in the analytics database, as shown in block 470.For example, physiological data indicating reduced pain symptoms can be considered a satisfactory application of the pain management therapy.","To add to the pain analytics database, the server system interface engine 106 executing on pain therapy device 100 can transmit one or more of the patient information (indicating the initial set of physiological measurements), the updated physiological measurements, the recommended pain management therapy (as derived from the pain analytics database), and/or the adjusted pain management therapy (as adjusted based on this individual patient's physiological responses) to the server system 130.The server system 130 stores the received information in patient analytics database 132.If the updated physiological data and/or patient feedback does not indicate reduced pain symptoms, a different pain management therapy may need to be selected.","In response to the lack of reduction of pain symptoms, the patient information, updated physiological measurements, recommended pain management therapy, and adjusted pain management therapy are first stored in the analytics database, as shown in block 480.This adds to the database and indicates a therapy that does not necessarily work for patients with characteristics similar to the user of pain therapy device 100.The process 400 then returns to block 420, where the therapy analysis engine 104 compares the patient information with pain analytics data to determine a different pain management therapy.","The process 400 continues until a satisfactory pain management therapy is found.","Any suitable computing system or group of computing systems can be used to implement the physician computing device 110 and the patient computing device 120 described in FIG.","1.For example, FIGS.","5-6 are block diagrams depicting examples of implementations of such components.","As shown in

interface application 122.The following paragraphs describe further illustrative embodiments for the pain therapy device 100.There may be provided a pain therapy device that is useful in treating various physiological conditions.","The device may include a controller, sensors and an applicator.","The applicator generally features a plurality of transducers that produce electrical, heat, cold and ultrasound energies respectively.","The controller provides the required electronics to control energies produced by the transducers.","The controller is configured to modify the intensity, timing, or duration of the different energies, which are applied over the treatment area (skin) over the feedback control signal obtained from the sensors.","Both the controller and the applicator may be cooperate either by wired communication or can communicate wirelessly.","They may be integrated into a single product.","The pain therapy for use herein can carry out therapeutic treatment using the lowest possible energy intensities in order to achieve a therapeutic effect.","One or more of a combination of electric stimulation (electroceuticals), thermal stimulation (thermoceuticals via application of heat, cold) or ultrasound (pulsed or continuous), when applied to the treatment area in a systematic manner, has been demonstrated to show synergistic effect leading to better and faster therapeutic relief Superficially applied heat follows a top-down heating mechanism through conduction and heat may not get transferred beyond top 1 cm to 2 cm depth of the tissue (note that skin and tissue beneath it are poor thermal conductors).","On the other hand, ultrasonic energy can heat up both surface and deep tissue (from 1 cm to 5 cm) easily as the acoustic energy absorbed by the tissue gets converted into thermal energy.","Because of these fundamentally distinct modes of heating (conductive heating vs. converted heating), use of ultrasound and superficial heat combination rapidly creates a thermal gradient across the treated tissue leading to significantly higher blood flow rates quickly unlike conventional single form of thermal energy based therapies.","Therefore, it is possible to provide improved oxygen supply to injured body part for sustained periods of time, and flush out unwanted inflammation causing chemicals to provide rapid and sustained pain relief Cold also follows a top-down thermal conduction, where cooling of the dermal and sub-dermal layers (top 1 cm to 2 cm) shows several beneficial effects with regard to treating acute injuries.","Cold can decrease cellular metabolism and causes vasoconstriction of the blood vessels in the area and decreases the inflammation in the area and thus the associated pain and swelling.","In combination with ultrasound, cold may provide an additive effect.","For example, combination of cold and ultrasound energies together can create an inverse thermal gradient for improved blood flow, that is, the surface temperatures of the top most tissue layer will be below body temperature, while the deep tissue temperatures will be above body temperature.","Indeed, such an inverse thermal gradient, which is practically impossible to accomplish from conventional thermal therapies may be extremely useful for safely heating deep tissue to 45-70° C. rapidly for shorter time periods for face lifting and cosmetic applications.","Providing these energies in a controlled pulsatile manner can help reduce the risk of adverse effects, while still achieving the desired therapeutic effect.","Because a larger volume of dermal and sub-dermal tissues can be exposed to the energies when used in combination, especially thermal energy and ultrasound, there may be increased blood flow around the treatment area providing fresh oxygen and nutrients, and increasing subsequent tissue metabolism.","Similarly, the combination of electric stimulation (e.g., TENS) and thermal stimulation may offer synergetic benefits both in terms of improving local blood flow and efficiently masking pain signals.","Therefore, combination therapies not only account for individual patient related physiologies, but also provide an opportunity to precisely fine tune or titrate body reflexes across the deep tissue to provide rapid pain relief and other related therapeutic benefits (e.g., faster tissue regeneration giving relief from pain, wound healing, blocking pain sensation reducing pain, inflammation, spasms, and other side effects).","In one example, pulsed heating may be synchronized with pulses of pressure waves such that both pulses reach the target simultaneously.","In another example, pulsed cooling may be synchronized with pulses of pressure waves such that both pulses reach the target simultaneously.","In another example, pulsed heating is followed by pulsed cooling and both are synchronized with pulses of pressure waves such that both pulses reach the target simultaneously.","In another example, TENS, ultrasound and surface heating can be synergistically applied to treat the entire cross section of the tissue.","In another example, TENS, ultrasound and cold could be synergistically applied to accomplish targeted goals.","The recent scientific advances made in medicine us realize that personalizing the medication or therapies is critical for achieving efficacious therapeutic benefits across the diverse population.","The current approaches of using physical medicine indiscriminately across the various patient population leads to application of inconsistent therapies, and dosages and results in inefficient or inferior therapies, which may be randomly successful or unsuccessful.","For example, the tissue thickness of a 300 pound person is different from 100 pound person, and so is the composition of the tissue, but if one applies electroceuticals or thermoceuticals identically to both these weight groups, the results may not be identical—after all, the applied energies are identical, but not the injured body parts.","Further, the pathophysiology of each individual is different, and it is difficult to provide universal medicine for pain without personalizing it, especially physical medicines that do not cause adverse side effects.","One more complex problem associated with pain is that patients' opinions/perceptions regarding pain are subjective and cannot be measured independently/objectively.","Patients' perceptions about pain (especially chronic pain) may dynamically change; their response to a particular therapy may also change either positively or negatively over a period of time.","Therefore, personalization of precisely dosed combination therapies accounting patient feedback provides an unprecedented opportunity to treat pain safely and efficiently.","FIG.","7 shows a schematic block diagram of an exemplary pain therapy device.","This device may be used with the treatment methods described herein.","The device includes a controller and applicator.","The power is provided by a battery or capacitor of a suitable power supply unit.","The controller includes a microprocessor unit and controls a plurality of electronic circuit modules for the generation of different energy, such as thermal energy (0 to 70° C., more specifically from about 0-50 ° C.) and ultrasound (0.2 to 20 MHz, or in other examples from about 0.1 to about 10 MHz).","Alternatively, or in addition, the controller may deliver electro stimulation to the body in a post or continuously in the frequency range of about 1-200 Hz, pulse amplitude in the range of 0 mA to 500 mA, pulse width in that 1 micro second to millisecond range.","The controller may be programmed for the duration, switching sequence and intensity of each of these energies.","The applicator may include transducers capable of delivering heat, cold and ultrasound and/or electro stimulation to the skin/treatment area.","The applicator also features a

and 8B show the schematic cross sections of different possible pain therapy device designs.","Controller (1) comprises of electronic circuitry (3), rechargeable battery (4), on/off switch (6) and an LED indicator (5).","FIG.","8A illustrates the integrated design where both the controller and applicator makes a single unit.","Whereas FIG.","8B illustrates the two piece design in which both the controller and applicator are two separate entities and are connected through a wire/wireless.","FIGS.","9A to 9C, FIGS.","10A and 10B, FIGS.","11A and 11B, FIGS.","12A and 12B, and FIGS.","13A and 13B illustrate schematic cross sections of different exemplary applicator designs.","The applicator generally includes an ultrasound transducer (8), heat/cold transducer (10), insulation layer (9), temperature sensors/PCB (11), top cover (7) and bottom cover.","In some embodiments, applicator may also include internal PCB, multiple sensors, and electrodes.","In some of the embodiments this also includes side support (13).","In some embodiments the ultrasonic energy from applicator is transferred into the body through conducting media.","U.S. Pat.","No.","9,710,607 provides more detail about these devices, the entire disclosure of which is incorporated herein by reference.","In one example, the power source used to operate the device can be a rechargeable battery, an AC power adapter and/or a capacitor.","The input power unit may be configured for delivering current of range 0.1 mA to 4000 mA and delivering potential of range 2V to 120V to deliver multiple therapies at different currents or voltages.","For example, the current and voltages used for accomplishing, heat, cold, ultrasonic and TENS (or IFT, interferential therapy) energies may be different.","The device can include a plurality of circuit blocks configured and connected to various transducers for converting the input energy to heat, cold and ultrasound.","This section may have a switch to keep the device in on/off/standby mode to conserve energy when not in use.","The standby function is optionally automated based on the program in the controller.","A controller can be provided for containing the required software for operation.","The controller also interfaces with the detecting transducers for the required computation for quantifying the detected values.","When various forms of energy are supplied to the treatment area via a combination effect of control signals, the controller and the transducer can supply pulses with a minimum duration of 1 millisecond or more.","The controller may be further configured/programmed for altering the outputs on the basis of the feedback signals provided by the sensors disposed over the said applicator.","Based on the settings and the program running in the controller, the exact temperature and duration of application of heat or cold or electric treatment or ultrasound can be precisely controlled by this circuit block.","Various durations of temperature and frequencies are possible.","The applicator can have an ultrasound sound transducer and heat and/or cold transducers or TENS (IFT) electrodes along with sensors that gather key diagnostic and therapy related information.","As shown in FIGS.","9A to 9C, 10A, 10B, 11A, 11B, 12A, 12B, 13A and 13B illustrate, these transducers may be aligned one above the other.","In one example, the ultrasound transducer may be positioned above the heat/cold transducer, or the ultrasound transducer can surround the heat/cold transducer and vice versa, or the transducers can be side by side, or the design may be an irregular design to utilize the produced energies efficiently and treat the physiological condition very effectively.","The applicator may also have temperature sensors placed on or around the heating/cooling element to measure the temperatures and send the information to the controller through feedback loop mechanism to maintain constant exposure temperatures.","The sensors can be configured for feedback control of the device.","For example, the sensors can provide control signals to the controller for the optimized and efficient use of the different energies to be applied over the treatment area.","The sensors (which may include ultrasonic transducers that have dual function as sensor and therapeutic agent) can provide additional information regarding blood flow, tissue thickness, tissue composition, tissue image, bone strength, callus stiffness, blood oxygen levels, pain-pressure sensitivity, applicator contact with body and so on.","This can reduce the power usage of the power source/battery and allow for prolonged use without repeated charging.","In use, a gel or other material may be positioned on a patient's skin.","This may help the ultrasound, electrical stimulation and any other form of physical medicine that needs an efficient conductive media to transfer energy into the body.","For example, thermal energy from ultrasound can only be transferred efficiently through a conductive (electrically or thermally or acoustically) gel, while thermal energy from superficial heating may be transferred directly into the body without including any additional conducting medium.","The electrical stimulation also requires conductive gel pads to pass electric current into the body and in between the electrodes.","Further the applicator may also require an adhesive tape to attach it to the body.","It is also possible that the adhesive pads could act as conductive elements, or vice versa.","The gel could be applied in the form of liquid, semi-solid, solid, suspension or slurry.","The applicators can also be attached to the body through strap mechanism.","Therefore, the applicator may come in direct contact with the body partially or fully through an additional conducting medium as required or applicator may come in contact with skin without any conductive medium, if applied therapy do not require such a medium.","In an exemplary embodiment, the method can include directing ultrasound waves at a tissue and heating the tissue with thermal energy.","The thermal energy pulses may be synchronized to arrive at the tissue simultaneously with the ultrasound waves within a preset range, and the heat of each thermal energy pulse can be dissipated in an environment that includes the tissue before a subsequent thermal energy pulse arrives at the tissue.","The deposited heat energy per pulse, the number of pulses, and the repetition rate of the pulses may be determined by a processor according to the temperature and the heat dissipation capability of the tissue.","The electrical energy can be delivered continuously or in pulses at low frequency (2-20 Hz) or high frequency (20 Hz to 200 Hz) in combination with pulsed or continuous thermoceuticals.","Therefore, the above-described intelligent pain management computer systems and methods for managing pain therapy may be implemented using a variety of pain therapy devices or physical medicine delivery systems described herein.","Additionally or alternatively, the method can include directing electro stimulation at the tissue as well.","The compact design of the disclosed device can give a patient the freedom to use the device on the move and/or at home, reducing the clinic visits.","The device can be used/placed on any part of the body and also for any ailment that will respond to these energies.","To provide further explanation, the following examples are provided as additional

more than one or two months to heal, may be required to monitor various health parameters on a regular basis in support of any treatment or therapy that he or she is undergoing or receiving.\",\n \"Today, advances in medical research enable a range of therapeutic options to treat a given disease, or ailment and/or their symptoms, where each of the proposed therapies targets a particular biochemical or physiochemical process underlying or associated with the disease to provide either a cure or relief from the disease symptoms.\",\n \"For example, if one were to consider various options available for treating pain symptoms, the possible diagnoses, medicaments and therapies are many; similarly there are several options available for accelerating fractured bone healing.\",\n \"It is possible that the therapy/medication a patient receives could be subjective and depend upon the particular doctor/physician, i.e., his/her background, expertise and past experiences.\",\n \"For example, a physiotherapist or an orthopedic physician may treat a pain symptom differently than a physician or pain management specialist.\",\n \"Although a doctor plays a critical role in diagnosing and prescribing the therapy, the patient (and his/her family members or care givers) also has great responsibility in complying with the prescription, and following the course of action for achieving improved health and better quality of life.\",\n \"However, unfortunately, depending upon the patient demographics and nature of the disease, health care management of pain management and implementation of pain management has become a daunting task and an expensive affair.\",\n \"For example, of the all diseases, chronic pain is one of the most underestimated health care problems in the world today, causing major consequences for the quality of life of the patients and the family members and has been a major burden on the health care system.\",\n \"The most common causes of chronic pain are musculoskeletal problems (fractures, dislocations, soft injuries) and inflammatory conditions, with back pain and arthritis pain symptoms accounting for a significant portion of the overall chronic pain population.\",\n \"The four most common ways to treat pain are: (1) pharmaceutical (e.g., analgesics, aspirin; NSAIDs, Ibuprofen, COX-2 inhibitors, celecoxib; opioids, morphine), (2) procedural (neuro-stimulators, pulsed radiofrequency, intrathecal), (3) psychological (behavioral, cognitive), and (4) physical (e.g., heat, cold, transcutaneous electric nerve simulation (TENS), therapeutic ultrasound, infrared, microwave or shortwave diathermy, electro-magnetic radiation, acupuncture, massage Although pharmaceutical methods (e.g., drugs) are most widely used for treating pain, individuals on over the counter or prescription drugs for pain are frequently dissatisfied with the results of the pharmaceutical treatment.\",\n \"Further, the adverse side effects that drugs may cause on prolonged usage is shifting the focus away from drugs toward alternate methods for managing chronic pain.\",\n \"The procedural methods are invasive, expensive and their effectiveness has been difficult to quantify.\",\n \"Psychological therapies often lack practicality and their success rates have been limited.\",\n \"Finally, physiotherapy based methods have been proven attractive, but they are inconvenient, require bulky/complex instruments, and regular office/hospital visits, all of which lowers compliance.\",\n \"In addition, these therapies are often not supported by quality clinical data despite tremendous advances made in understanding pathophysiology and pain signaling.\",\n \"Although, a number of physical medicine/modalities based therapies have been administered to

therapies or treatment approaches for healing fractured bones include delivering bone morphogenetic proteins (“BMPs”), platelet-rich plasma (PRP), or anabolic agents such as teriparatide (“TPD”).\",\n

ultrasound to one patient having one body composition will not achieve the same result as delivering that same amount of ultrasound to a different patient having a different body composition, or for

In a specific example, the device can deliver thermal energy at about 42° C. Application of ultrasound therapies stimulates tissue beneath the skin's surface using sound waves.\",\n \"Exemplary ranges include from about 0.1 MHz to about 10 MHz.\",\n \"Other specific ranges may include from about 0.5-3.0 MHz (with tolerances including±20%) A specific low intensity pulsed ultrasound frequency may be about 1.5 MHz.\",\n \"In some examples, the ultrasound may be pulsed.\",\n \"In some examples, the ultrasound may be pulsed while the tissue temperature is altered between 0 to 50° C. In some examples, the ultrasound may be delivered continuously.\",\n \"In further examples, the ultrasound may vacillate between continuous delivery and pulsed delivery.\",\n \"The ultrasound frequency range delivered may depend upon set parameters, for example, may be based upon the patient's tissue composition.\",\n \"The intensity of the ultrasound may range from about 0.005 W/cm2 to about 3.0 W/ cm2.In some examples, ultrasound can cause a temperature rise up to 10° C. in 2-8 cm deep tissue or at least up to 5° C. The ultrasound can also imparts non-thermal effects such as acoustic streaming and cavitation to provide pain relief.\",\n \"Thermal changes also result in activation of a wide variety of thermal receptors (transient receptor potential channels (TRP)) in the skin/tissue that range from 0-60° C. and may mask pain signals to the brain.\",\n \"Activation of these receptors either chemically (e.g., menthol activates TRPA1, TRPM8, while capsaicin activates TRPV1, TRPV3) or physically can lead to masking of the pain sensation.\",\n \"In some embodiments of the present disclosure, the pain signal to the brain is masked by providing a method/mechanism to maximize/overwhelm the signal(s) from an individual or multiple TRP channels located around painful musculoskeletal region.\",\n \"The distribution ratio of various temperature sensitive receptors in the body varies depending upon the body location.\",\n \"For example, upper part of the body comprises more heat temperature receptors than cold temperature receptors.\",\n \"The present inventors believe that pulsing low intensity ultrasound while controlling the tissue temperature help minimize the losses of ultrasound energy due to attenuation and increases ultrasound velocities inside the tissue, and thereby encourages more effective and efficient bone healing.\",\n \"Preheating or Pre-cooling or Pre-conditioning of the tissue around injured area (that is injured bone or tissue) can help encourage greater penetration of the ultrasound.\",\n \"Without wishing to be bound to any theory, it is believed that raising the patient's tissue temperature to about 50° C., while also delivering ultrasound waves (pulsed or continuous), can help reach the underlying bone tissue more effectively (i.e., with higher velocities and low attenuation coefficients).\",\n \"It is believed that this treatment may help improve bone healing by up to about 30 to 40% or even more.\",\n \"However, not all patients have the same tissue composition.\",\n \"Some patients may present with more fat tissue, others with more muscle tissue, and different densities of tissue or body mass indices will require different dosages for treatment to ensure the right dosage of ultrasound energy is experienced by the injured bones/tissue therapy point.\",\n \"Ultrasound waves are absorbed more as they extend deeper into tissue.\",\n \"The ultrasound intensity that reaches the bone will vary based on the delivered parameters such as ultrasound frequency, intensity, pulsing profile, tissue temperature, tissue thickness/composition in a therapeutic area.\",\n \"Embodiments disclosed herein also include computer-implemented therapy that applies electroceuticals as electrical stimulation of nerves.\",\n \"In electric stimulation, electrical current at distinct voltages, frequencies and intensities is delivered to the skin through electrodes (e.g., TENS, electric muscle stimulation, EMS, or neuromuscular electric stimulation, LAMES, IFT, inferential therapy).\",\n \"Pain is relieved by means of the pain gate mechanism involving activation of sensory fibers that mask the pain and/or suppressing of pain signals to the brain.\",\n \"It is also believed possible that delivery of electric stimulation may help healing of fractured bones, the bone healing may be accelerated in conjunction with low intensity pulsed ultrasound while keeping the tissue temperature at native body temperature or by externally altering it with the aid of thermoceuticals.\",\n \"Additionally, electrical stimulation can generate a physiological response to the irritation produced by electrical stimuli which leads to the release of endorphins.\",\n \"Electrically pulsed stimulation also causes enhanced localized muscle activity and thereby increases blood circulation to remove metabolic toxins, thereby reducing pain symptoms and/or may encourage bone growth.\",\n \"The electroceuticals can be applied to the body using either low (1-20 Hz) or high frequencies (20-200 Hz) for treating pain and several other therapeutic indications.\",\n \"In other words, the energy delivered may range from about 2-200 Hz, or any range there between.\",\n \"The voltages used for electric stimulation may vary from 3 V to 120V, while the wave forms applied could assume different shapes such as square, asymmetrical biphasic, and symmetrical biphasic.\",\n \"In other examples, the range may be from 10 V to 120V.\",\n \"The stimulation could be applied to the body continuously or in pulsed mode or in burst mode to trigger different therapeutic mechanisms for treating ailments.\",\n \"Although, the therapeutic mechanism behind electric stimulation has not yet been unequivocally established, it is generally believed that electric stimulation enables the body to produce its own endorphins, increases local blood flow and mask pain signals via pain gate mechanism and several other hypotheses as proposed in the literature.\",\n \"It is believed that combining electrical stimulation, thermal therapy, and ultrasound together can offer efficient pain management options.\",\n \"It is also believed that combining electrical stimulation, thermal and ultrasound therapies together can offer rapid healing of fractured bones.\",\n \"For any of the treatments described, the delivery of the thermal therapy, ultrasound, and/or electrical stimulation or any combination thereof described may be pulsed.\",\n \"The delivery of the heat therapy, ultrasound, and/or electrical stimulation or any combination thereof described may be continuous.\",\n \"The delivery of the heat therapy, ultrasound, and/or electrical stimulation or any combination thereof described may be alternated.\",\n \"The delivery of the heat therapy, ultrasound, and/or electrical stimulation or any combination thereof described may alternate between pulsed and/or continuous.\",\n \"The particular therapy may be optimized for the patient.\",\n \"If pulsed, it is possible for the time range of the pulsing to the separated by microseconds, milliseconds or seconds.\",\n \"Typically, electric stimulation pulsing could be in the order of micro to milliseconds.\",\n \"Acoustic pulsing could be in the order of milliseconds.\",\n \"Thermal pulsing may be in the order of seconds to minutes.\",\n \"In some embodiments, the therapy device may communicate with a physician computing device to provide personalized care via application of personalized pain management therapy through customized application of electroceuticals, and thermoceuticals.\",\n \"For example, a physician computing device can receive inputs from a healthcare provider for setting the initial physical therapy and adjusting the therapy as the treatment is applied.\",\n \"The initial pain management therapy may also be set via a patient computing device communicatively coupled to the pain therapy device.\",\n \"The initial pain management therapy indicates the specific combination and intensity levels of electroceuticals, thermoceuticals, and/or ultrasound.\",\n \"During treatment, sensors communicatively coupled to the pain management device detect the physiological responses resulting from the application of the pain management therapy.\",\n \"The pain therapy device also receives patient feedback indicating pain relief scores via a user interface for the patient computing device (or entered directly from the graphic user interface of pain therapy device).\",\n \"The pain therapy device continues to apply the physical therapies (e.g., the electroceuticals, thermoceuticals, ultrasound, acupuncture, pressure/massage based therapies) indicated in the therapy until the physiological responses/patient feedback indicates a threshold pain management level has been reached.\",\n \"For example, as the pain management therapy is applied, the sensors coupled to the pain therapy device may detect an increase in blood flow or an increase in blood-oxygen levels at the localized area of pain.\",\n \"If the rate of blood flow (or bone healing) and the value of the blood-oxygen levels reach a threshold value specified in the pain management treatment, the pain therapy device reduces or completes the application of the physical therapies.\",\n \"Similarly, the pain therapy device may receive feedback from the patient via a user interface indicating the pain has decreased (e.g., by indicating a pain relief score on a 0-5 or a 0-10 scale).\",\n \"In response, the pain therapy device continues or completes or modifies the application of the physical therapies.\",\n \"For example, a therapy analysis engine executing on the pain therapy device receives updates from a physiological data collection engine and from a patient feedback interface and uses the collected information to iterate the dosage of the physical medicine.\",\n \"Embodiments disclosed herein also recognize that the demographics of chronic pain patients (or patients with fractured bones) and the physical therapy requirements are unique.\",\n \"It has been well documented in the literature that people with certain pain symptoms, do not respond to electroceuticals and thermoceuticals (or even pharmaceuticals) in similar fashion.\",\n \"For example, some people may get pain relief using TENS, and others may not respond to such a therapy at all, and may even have allergic reaction.\",\n \"Therefore, the physiology of individuals and the patient feedback plays an extremely important role in determining the ideal/optimal therapy.\",\n \"In addition to being responsive to patient feedback and physiological response from an applied pain therapy, the pain therapy device further tailors or “titrates” physical medicine(s) dosage (energy type(s), intensity, exposure depth and duration) based on the patient demographics (e.g.\",\n \"age, gender, body mass index, ethnicity, pre-existing health conditions and cultural background).\",\n \"For example, the server system includes a patient analytics database that stores patient demographics and applied therapy information (e.g., the specific combination of the physical therapies applied and the dosage levels) as well as information on outcomes of the applied pain management therapy on multiple individuals that had previously applied pain management therapies.\",\n \"The database may comprise enormous amount of information from hundreds or thousands or even millions of individual patients and provides a powerful tool to conduct data analytics (analogous to an automated virtual/crowd-sourced clinical study that constantly gets updated with addition of ever increasing data sets) and customize the pain therapy for individuals either in an automated fashion or through prompt response from the physician.\",\n \"The analytics data can indicate the statistical likelihood of satisfactory pain management outcomes from application of the pain therapy.\",\n \"The pain therapy device connects with the server system over a network to compare the patient information for a specific patient with the patient information in the analytics data to identify a subset of individuals that have similar characteristics as the patient.\",\n \"For example, the therapy analysis engine may comprise a software application or software module executing in either the pain therapy device or the server system.\",\n \"The therapy analysis engine identifies a subset of individuals that are with the same age range, gender, body mass index, and other pre-existing medical conditions, pain therapies received in the past or on-going (including drugs, or surgical procedures or alternate medicines), physical characteristics as the patient.\",\n \"The therapy analysis engine also identifies one or more pain management therapies that were applied to the subset of individuals that resulted in favorable pain management outcome.\",\n \"The pain therapy device can thus personalize the applied pain management therapy based on subjective data such as patient feedback, objective data such as physiological responses to the applied therapy, as well as analytics data that can indicate the personalized pain management therapy as collected from other patients with similar characteristics as the patient.\",\n \"The pain therapy device can transfer the patient information and the pain management therapy information through wireless connectivity to the database for storage in the analytics system.\",\n \"In this way, the pain management adds the current patient's information (e.g., demographic information, symptoms, etc.\",\n \"), applied pain management therapy, and therapy outcomes (e.g., patient relief scores and physiological changes resulting from the therapy) to the analytics database.\",\n \"These illustrative aspects and examples are given to introduce the reader to the general subject matter discussed here and are not intended to limit the scope of the disclosed concepts.\",\n \"The following sections describe various additional features and examples with reference to the drawings in which like numerals indicate like elements, and directional descriptions may be used to describe the illustrative aspects but, like the illustrative aspects, should not be used to limit the present disclosure.\",\n \"FIG.\",\n \"1 is a block

110.The patient computing device 120 and the physician computing device 110 may comprise any suitable computing device, such as a personal computer, a tablet computer, or a cell phone.\",\n \"The initial pain management therapy may be personalized based on patient information (i.e.\",\n \"information on the user of pain therapy device 100).\",\n \"For example, the physician computing device 110 includes a physician interface application 112 that presents options for inputting patient information (e.g., patient pain symptoms, demographic information, medical history, and additional information) and a personalized pain management therapy based on the patient information.\",\n \"A healthcare provider operating the physician computing device 110 can prescribe the personalized pain management therapy via the physician interface application 112.For example, the physician interface application 112 presents a user interface for selecting a physical medicine via a combination of

patient interface application 122, the patient provides inputs regarding the personalized pain management therapy as discussed or otherwise prescribed by the healthcare provider.\",\n \"The personalized pain management therapy can thus be administered via the health care provider or self-administered via the patient.\",\n \"One or more applicators 124 connected to the pain therapy device 100 apply the personalized pain management therapy input via physician interface application 112 or patient interface application 122 or directly through physical therapy device 100.The personalized pain management therapy comprises of physical therapies that include a combination of electrical stimulation, hot and cold stimulation, and ultrasonic pulses.\",\n \"In some embodiments, based on feedback received from physician computing device 110 and patient computing device 120, the therapy analysis engine 104 executing on the pain therapy device 100 adjusts the applied personalized pain therapy accordingly.\",\n \"For example, inputs received via a patient feedback interface 111 presented on physician computing device 110 or patient feedback interface 121 presented on patient computing device 120 may indicate a pain relief score from a value of 0-10, with 10 indicating the most intense pain and 0 indicating no pain.\",\n \"It should be understood that other values or indications could be used, such as emoticons, descriptive text, color, or a selection on a continuum.\",\n \"As the personalized pain management therapy is applied via applicator 124, a pain relief score may be received indicating a low measurement of pain.\",\n \"A satisfactory application of personalized pain management therapy can be based, for example, on reduction of a pain relief score by a certain pre-programmed threshold.\",\n \"In response, the therapy analysis engine 104 may adjust the personalized pain management therapy by adjusting the dosages and intensities of physical therapies to accommodate for lesser pain.\",\n \"The feedback comprising the pain relief score may also be received directly on a user interface on pain therapy device 100.For example, memory 101 of patient therapy device 100 may include program code for executing a patient feedback interface 107 used to receive feedback to the therapy from the patient.\",\n \"In further embodiments, the therapy

data collection engine 102 executing in memory 101 of pain therapy device 100 may receive information on the blood-oxygen levels, rate of blood flow, and tissue thickness from connected sensors.\",\n \"The personalized pain management therapy may include instructions on applying physical therapies at specific dosage levels and adjust the applied physical therapies in response to changes in physiological measurements.\",\n \"For example, the therapy analysis engine 104 may apply a combination of electrical stimulation at a certain intensity level, heat stimulation at a certain temperature, and ultrasonic pulses until a physiological responses indicate a blood flow of a certain rate.\",\n \"Once the specified blood flow rate (or blood oxygen levels) is achieved, pain therapy device 100 may apply physical therapies with different intensity levels/temperature values.\",\n \"This process continues until the pain management therapy is complete (e.g., the prescribed physical therapies are fully administered).\",\n \"In additional embodiments, patient symptoms and demographic information on the patient (i.e.\",\n \"user of pain therapy device 100) may be compared with analytics information stored on multiple other patients to determine the personalized pain management therapy.\",\n \"The analytics data is stored on a patient analytics database 132 in server system

pain, and a numeric pain relief score indicating the severity of the pain at the specified location.\",\n \"Pain symptoms can also be more or less detailed.\",\n \"All common chronic pains and musculoskeletal pains such as back pain, neck pain, shoulder pain, arthritis, muscle spasms, tendonitis, bursitis, sports injuries are either visually or verbally represented.\",\n \"Any other form of pain that requires diagnosis by qualified physician (e.g., fibromyalgia) or that cannot be treated using pain therapy device (visceral pain, especially involving cutting, burning and/or involving internal organ damage) will not be included in the system as a default.\",\n \"Patient physiological data includes physiological measurements of a measured tissue area.\",\n \"Physiological measurements include, for example, the measured rate of blood flow, blood-oxygen levels, tissue depth, tissue composition, tissue temperature, bone strength, callus stiffness, acoustic emissions/reflections from fractured/partially healed/fully healed or normal/healthy bones, ultrasound velocity and attenuation across a healing fractured bone and other measurements.\",\n \"The patient information may be received via inputs in physician interface application 112 in physician computing device 110 or patient interface application 122 in patient computing device 120 and transmitted to pain therapy device 100.In other embodiments, the patient information can be directly entered in pain therapy device 100 via a user interface on the pain therapy device 100.While the pain therapy device 100 can process the patient information to determine the personalized pain management therapy, in other embodiments, the patient information is transmitted to server system 130.Process 400 also includes comparing the received patient information with pain analytics data compiled on a plurality of individuals to determine a recommended pain management therapy, as shown in block 420.For example, the server system 130 includes a patient analytics database 132 that stores the pain analytics data on numerous prior patients.\",\n \"The pain therapy device 100 can transmit the patient information to the server system 130 for the comparison.\",\n \"In other embodiments, the pain therapy device 100 can receive the analytics data from the server system 130 via network 115 for the comparison.\",\n \"Therapy analysis engine 104 (executing in pain therapy device 100) or therapy analysis engine 131 (executing in server system 130) compares patient information with the pain analytics data to determine a subset of individuals with similar characteristics as the patient as explained above with respect to FIG.\",\n \"1.Additionally, therapy analysis engine 104 or therapy analysis engine 131 identifies the recommended pain management therapy that previously depicted a satisfactory outcome (e.g., by lower received pain relief scores from other patients, from objective measurements of physiological data indicating lesser pain symptoms).\",\n \"As shown in block 430, the recommended pain management therapy is applied via an applicator device 124.For example, the applicator device 124 provides one or more electroceuticals, or thermoceuticals, or ultrasound, or any combination at a specific frequency, intensity, and/or duration as specified by the recommended pain management therapy.\",\n \"Note in some aspects, the recommended pain management therapy can be overridden and manually input via inputs received from physician computing device 110 or patient computing device 120.After application of the recommended pain management therapy (which is initially based on the analytics data on pain management therapies applied on other patients), the pain therapy device 100 can further adjust and personalize the therapy based on feedback from the patient.\",\n \"As shown in block 440, process 400 further involves receiving, from one or more sensors, updated physiological data reflecting changes in the patient physiological data, and subjective patient feedback (in the form of pain score) in response to the applied recommended pain management therapy.\",\n \"For example, as the recommended pain management therapy is applied by applicator 124, sensors 230-238 measure changes in the temperature, blood flow rate, blood-oxygen levels, and tissue thickness resulting from the therapy.\",\n \"The sensor data can be received via a physiological data collection engine 102.The changes in the physiological data in response to the applied pain management therapy can be considered objective feedback to the pain management therapy.\",\n \"Note that while the type of feedback in response to the applied pain management therapy described in block 440 is feedback from physiological data, other types of feedback are also possible.\",\n \"For example, the pain therapy device 100 can receive subjective feedback from the patient in the form of a patient relief score (e.g., a numeric value from 0-10) as discussed above with respect to FIG.\",\n \"1.The therapy analysis engine 104 can adjust the applied pain management therapy (or bone healing therapy) in response to the changes in physiological data (or in response to other feedback), as shown in block 450.For example, the applied voltage or current of the electrical stimulation, the temperature of the heating element, or the intensity of the ultrasonic pulses can be adjusted based on the changes in the physiological data or sensor data or based on patient feedback.\",\n \"Probably, the pain relief scores from patients in conjunction with objective physiological data (whenever available) could be used to adjust or titrate the dosage of the physical medicine involving single or combination of therapies.\",\n \"For example, the thermoceutical dosage may be defined by three parameters, i.e., intensity (e.g., temperature range; frequency, intensity and duty cycle in case of ultrasound), energy exposure time, and course duration for a given tissue thickness or composition (or BMI).\",\n \"If the physical medicine dosage delivered does not increase the tissue temperature or raise the deep tissue temperature in stipulated time frame and/or for sustained time period, and/or do not provide pain relief to the patient, one could consider the dosage delivered is sub optimal.\",\n \"At present, our understanding about how distinct physical modalities or their combination therapies at what dosage levels provide efficient pain relief is relatively limited.\",\n \"Further complexity stems from the fact that pain is a subjective personal experience, and the physiology of individual is different from each other and the way each individual responds to given therapy is unknown.\",\n \"If a patient does not respond to a particular electroceutical or thermoceutical pain therapy, it is not generally implied that the given therapy does not work; it only implies that given therapy is not appropriate for that patient.\",\n \"Therefore, it is important to identify the patterns from various therapies provided to patients with diverse backgrounds and profiles to develop a personalized pain therapy.\",\n \"Typically, the dosage delivered will always be within the safety limitations as outlined by data published in the literature, the dosages will be titrated based on positive response from patients (i.e., lower pain scores).\",\n \"Once adequate data is accumulated from patient responses, it is possible to correlate pain relief (or rate of bone healing) measured in response to given physical medicine dosage with quantifiable physiological data or body reflex related measurements (e.g., increase local blood flow of injured body part, thermal imaging, tissue temperatures, blood oxygen levels, sensitivity to pressure etc.)\",\n \"and constitutes one of the inventive aspect of this innovation.\",\n \"As shown in block 460, the therapy analysis engine 104 makes a determination as to whether the updated physiological data indicates reduced pain symptoms (or faster bone healing).\",\n \"For example, the physiological changes in treated body part may include vasodilation, vasoconstriction as quantified by blood flow volume or velocity or by variation in blood oxygen levels or simply by measurement of tissue temperature or measurement of pressure sensitivity to pain (using algometer) or it could even include identification/measurement of certain cellular or molecular changes or electrical signals caused in response to external stimulation.\",\n \"If the updated physiological data or patient feedback indicates reduced pain symptoms (it is possible that subjective and objective evaluation results may not converge, the patient feedback coupled with statistics may precede physiological measurements), the patient information, patient feedback, the updated physiological data, the recommended pain management therapy, and the adjusted pain management therapy are stored in the analytics database, as shown in block 470.For example, physiological data indicating reduced pain symptoms can be considered a satisfactory application of the pain management therapy.\",\n \"To add to the pain analytics database, the server system interface engine 106 executing on pain therapy device 100 can transmit one or more of the patient information (indicating the initial set of physiological measurements), the updated physiological measurements, the recommended pain management therapy (as derived from the pain analytics database), and/or the adjusted pain management therapy (as adjusted based on this individual patient's physiological responses) to the server system 130.The server system 130 stores the received information in patient analytics database 132.If the updated physiological data and/or patient feedback does not indicate reduced pain symptoms, a different pain management therapy may need to be selected.\",\n \"In response to the lack of reduction of pain symptoms, the patient information, updated physiological measurements, recommended pain management therapy, and adjusted pain management therapy are first stored in the analytics database, as shown in block 480.This adds to the database and indicates a therapy that does not necessarily work for patients with characteristics similar to the user of pain therapy device 100.The process 400 then returns to block 420, where the therapy analysis engine 104 compares the patient information with pain analytics data to determine a different pain management therapy.\",\n \"The process 400 continues until a satisfactory pain management therapy is found.\",\n \"Any suitable computing system or group of computing systems can be used to implement the physician computing device 110 and the patient computing device 120 described in FIG.\",\n \"1.For example, FIGS.\",\n \"5-6 are block diagrams depicting examples of

for the pain therapy device 100.There may be provided a pain therapy device that is useful in treating various physiological conditions.\",\n \"The device may include a controller, sensors and an applicator.\",\n \"The applicator generally features a plurality of transducers that produce electrical, heat, cold and ultrasound energies respectively.\",\n \"The controller provides the required electronics to control energies produced by the transducers.\",\n \"The controller is configured to modify the intensity, timing, or duration of the different energies, which are applied over the treatment area (skin) over the feedback control signal obtained from the sensors.\",\n \"Both the controller and the applicator may be cooperate either by wired communication or can communicate wirelessly.\",\n \"They may be integrated into a single product.\",\n \"The pain therapy for use herein can carry out therapeutic treatment using the lowest possible energy intensities in order to achieve a therapeutic effect.\",\n \"One or more of a combination of electric stimulation (electroceuticals), thermal stimulation (thermoceuticals via application of heat, cold) or ultrasound (pulsed or continuous), when applied to the treatment area in a systematic manner, has been demonstrated to show synergistic effect leading to better and faster therapeutic relief Superficially applied heat follows a top-down heating mechanism through conduction and heat may not get transferred beyond top 1 cm to 2 cm depth of the tissue (note that skin and tissue beneath it are poor thermal conductors).\",\n \"On the other hand, ultrasonic energy can heat up both surface and deep tissue (from 1 cm to 5 cm) easily as the acoustic energy absorbed by the tissue gets converted into thermal energy.\",\n \"Because of these fundamentally distinct modes of heating (conductive heating vs. converted heating), use of ultrasound and superficial heat combination rapidly creates a thermal gradient across the treated tissue leading to significantly higher blood flow rates quickly unlike conventional single form of thermal energy based therapies.\",\n \"Therefore, it is possible to provide improved oxygen supply to injured body part for sustained periods of time, and flush out unwanted inflammation causing chemicals to provide rapid and sustained pain relief Cold also follows a top-down thermal conduction, where cooling of the dermal and sub-dermal layers (top 1 cm to 2 cm) shows several beneficial effects with regard to treating acute injuries.\",\n \"Cold can decrease cellular metabolism and causes vasoconstriction of the blood vessels in the area and decreases the inflammation in the area and thus the associated pain and swelling.\",\n \"In combination with ultrasound, cold may provide an additive effect.\",\n \"For example, combination of cold and ultrasound energies together can create an inverse thermal gradient for improved blood flow, that is, the surface temperatures of the top most tissue layer will be below body temperature, while the deep tissue temperatures will be above body temperature.\",\n \"Indeed, such an inverse thermal gradient, which is practically impossible to accomplish from conventional thermal therapies may be extremely useful for safely heating deep tissue to 45-70° C. rapidly for shorter time periods for face lifting and cosmetic applications.\",\n \"Providing these energies in a controlled pulsatile manner can help reduce the risk of adverse effects, while still achieving the desired therapeutic effect.\",\n \"Because a larger volume of dermal and sub-dermal tissues can be exposed to the energies when used in combination, especially thermal energy and ultrasound, there may be increased blood flow around the treatment area providing fresh oxygen and nutrients, and increasing subsequent tissue metabolism.\",\n \"Similarly, the combination of electric stimulation (e.g., TENS) and thermal stimulation may offer synergetic benefits both in terms of improving local blood flow and efficiently masking pain signals.\",\n \"Therefore, combination therapies not only account for individual patient related physiologies, but also provide an opportunity to precisely fine tune or titrate body reflexes across the deep tissue to provide rapid pain relief and other related therapeutic benefits (e.g., faster tissue regeneration giving relief from pain, wound healing, blocking pain sensation reducing pain, inflammation, spasms, and other side effects).\",\n \"In one example, pulsed heating may be synchronized with pulses of pressure waves such that both pulses reach the target simultaneously.\",\n \"In another example, pulsed cooling may be synchronized with pulses of pressure waves such that both pulses reach the target simultaneously.\",\n \"In another example, pulsed heating is followed by pulsed cooling and both are synchronized with pulses of pressure waves such that both pulses reach the target simultaneously.\",\n \"In another example, TENS, ultrasound and surface heating can be synergistically applied to treat the entire cross section of the tissue.\",\n \"In another example, TENS, ultrasound and cold could be synergistically applied to accomplish targeted goals.\",\n \"The recent scientific advances made in medicine us realize that personalizing the medication or therapies is critical for achieving efficacious therapeutic benefits across the diverse population.\",\n \"The current approaches of using physical medicine indiscriminately across the various patient population leads to application of inconsistent therapies, and dosages and results in inefficient or inferior therapies, which may be randomly successful or unsuccessful.\",\n \"For example, the tissue thickness of a 300 pound person is different from 100 pound person, and so is the composition of the tissue, but if one applies electroceuticals or thermoceuticals identically to both these weight groups, the results may not be identical—after all, the applied energies are identical, but not the injured body parts.\",\n \"Further, the pathophysiology of each individual is different, and it is difficult to provide universal medicine for pain without personalizing it, especially physical medicines that do not cause adverse side effects.\",\n \"One more complex problem associated with pain is that patients' opinions/perceptions regarding pain are subjective and cannot be measured independently/objectively.\",\n \"Patients' perceptions about pain (especially chronic pain) may dynamically change; their response to a particular therapy may also change either positively or negatively over a period of time.\",\n \"Therefore, personalization of precisely dosed combination therapies accounting patient feedback provides an unprecedented opportunity to treat pain safely and efficiently.\",\n \"FIG.\",\n \"7 shows a schematic block diagram of an exemplary pain therapy device.\",\n \"This device may be used with the treatment methods described herein.\",\n \"The device includes a controller and applicator.\",\n \"The power is provided by a battery or capacitor of a suitable power supply unit.\",\n \"The controller includes a microprocessor unit and controls a plurality of electronic circuit modules for the generation of different energy, such as thermal energy (0 to 70° C., more specifically from about 0-50 ° C.) and ultrasound (0.2 to 20 MHz, or in other examples from about 0.1 to about 10 MHz).\",\n \"Alternatively, or in addition, the controller may

different possible pain therapy device designs.\",\n \"Controller (1) comprises of electronic circuitry (3), rechargeable battery (4), on/off switch (6) and an LED indicator (5).\",\n \"FIG.\",\n \"8A

(10), insulation layer (9), temperature sensors/PCB (11), top cover (7) and bottom cover.\",\n \"In some embodiments, applicator may also include internal PCB, multiple sensors, and electrodes.\",\n \"In some of the embodiments this also includes side support (13).\",\n \"In some embodiments the ultrasonic energy from applicator is transferred into the body through conducting media.\",\n \"U.S. Pat.\",\n \"No.\",\n \"9,710,607 provides more detail about these devices, the entire disclosure of which is incorporated herein by reference.\",\n \"In one example, the power source used to operate the device can be a rechargeable battery, an AC power adapter and/or a capacitor.\",\n \"The input power unit may be configured for delivering current of range 0.1 mA to 4000 mA and delivering potential of range 2V to 120V to deliver multiple therapies at different currents or voltages.\",\n \"For example, the current and voltages used for accomplishing, heat, cold, ultrasonic and TENS (or IFT, interferential therapy) energies may be different.\",\n \"The device can include a plurality of circuit blocks configured and connected to various transducers for converting the input energy to heat, cold and ultrasound.\",\n \"This section may have a switch to keep the device in on/off/standby mode to conserve energy when not in use.\",\n \"The standby function is optionally automated based on the program in the controller.\",\n \"A controller can be provided for containing the required software for operation.\",\n \"The controller also interfaces with the detecting transducers for the required computation for quantifying the detected values.\",\n \"When various forms of energy are supplied to the treatment area via a combination effect of control signals, the controller and the transducer can supply pulses with a minimum duration of 1 millisecond or more.\",\n \"The controller may be further configured/programmed for altering the outputs on the basis of the feedback signals provided by the sensors disposed over the said applicator.\",\n \"Based on the settings and the program running in the controller, the exact temperature and duration of application of heat or cold or electric treatment or ultrasound can be precisely controlled by this circuit block.\",\n \"Various durations of temperature and frequencies are possible.\",\n \"The applicator can have an ultrasound sound transducer and heat and/or cold transducers or TENS (IFT) electrodes along with sensors that gather key diagnostic and therapy related information.\",\n \"As shown in FIGS.\",\n \"9A to 9C, 10A, 10B, 11A, 11B, 12A, 12B, 13A and 13B illustrate, these transducers may be aligned one above the other.\",\n \"In one example, the ultrasound transducer may be positioned above the heat/cold transducer, or the ultrasound transducer can surround the heat/cold transducer and vice versa, or the transducers can be side by side, or the design may be an irregular design to utilize the produced energies efficiently and treat the physiological condition very effectively.\",\n \"The applicator may also have temperature sensors placed on or around the heating/cooling element to measure the temperatures and send the information to the controller through feedback loop mechanism to maintain constant exposure temperatures.\",\n \"The sensors can be configured for feedback control of the device.\",\n \"For example, the sensors can provide control signals to the controller for the optimized and efficient use of the different energies to be applied over the treatment area.\",\n \"The sensors (which may include ultrasonic transducers that have dual function as sensor and therapeutic agent) can provide additional information regarding blood flow, tissue thickness, tissue composition, tissue image, bone strength, callus stiffness, blood oxygen levels, pain-pressure sensitivity, applicator contact with body and so on.\",\n \"This can reduce the power usage of the power source/battery and allow for prolonged use without repeated charging.\",\n \"In use, a gel or other material may be positioned on a patient's skin.\",\n \"This may help the ultrasound, electrical stimulation and any other form of physical medicine that needs an efficient conductive media to transfer energy into the body.\",\n \"For example, thermal energy from ultrasound can only be transferred efficiently through a conductive (electrically or thermally or acoustically) gel, while thermal energy from superficial heating may be transferred directly into the body without including any additional conducting medium.\",\n \"The electrical stimulation also requires conductive gel pads to pass electric current into the body and in between the electrodes.\",\n \"Further the applicator may also require an adhesive tape to attach it to the body.\",\n \"It is also possible that the adhesive pads could act as conductive elements, or vice versa.\",\n \"The gel could be applied in the form of liquid, semi-solid, solid, suspension or slurry.\",\n \"The applicators can also be attached to the body through strap mechanism.\",\n \"Therefore, the applicator may come in direct contact with the body partially or fully through an additional conducting medium as required or applicator may come in contact with skin without any conductive medium, if applied therapy do not require such a medium.\",\n \"In an exemplary embodiment, the method can include directing ultrasound waves at a tissue and heating the tissue with thermal energy.\",\n \"The thermal energy pulses may be synchronized to arrive at the tissue simultaneously with the ultrasound waves within a preset range, and the heat of each thermal energy pulse can be dissipated in an environment that includes the tissue before a subsequent thermal energy pulse arrives at the tissue.\",\n \"The deposited heat energy per pulse, the number of pulses, and the repetition rate of the pulses may be determined by a processor according to the temperature and the heat dissipation capability of the tissue.\",\n \"The electrical energy can be delivered continuously or in pulses at low frequency (2-20 Hz) or high frequency (20 Hz to 200 Hz) in combination with pulsed or continuous thermoceuticals.\",\n \"Therefore, the above-described intelligent pain management computer systems and methods for managing pain therapy may be implemented using a variety of pain therapy devices or physical medicine delivery systems described herein.\",\n \"Additionally or alternatively, the method can include directing electro stimulation at the tissue as well.\",\n \"The compact design of the disclosed device can give a patient the freedom to use the device on the move and/or at home, reducing the clinic visits.\",\n \"The device can be used/placed on any part of the body and also for any ailment that will respond to these energies.\",\n \"To provide further explanation, the following examples are

the tension spring 124M of the urging member 120RM urges the first support part 78M upward through the base part 126M of the urging member 120RM.","Similarly, the tension spring 124M of the urging member 120LM urges the second support part 85M upward through the base part 126M of the urging member 120LM.","Due to the upward urging of the process cartridge 17M by the urging members 120RM and 120LM, the seal 92M of the first conveying tube 77M and the seal 69M on the input tube 66M of the mounting unit 53M contact each other with pressure.","At this time, the opening 70M formed in the first conveying tube 77M is in vertical communication with the opening 68M formed in the mounting unit 53M.","In this state, the process cartridge 17M is in the first position, as shown in FIG.","6.To remove the process cartridge 17M from the main casing 2, the cover 8 is first moved from its closed position to its open position shown in FIG.","7.At this time, the cover 8 pulls the interlocking member 174M downward and the interlocking member 174M in turn pulls the connector tube 172M downward, causing the waste toner conveying tube 163 to rotate counterclockwise in a rear view and the connector tube 172M to move into its non-communication position.","The connector tube 172M is configured to move from its communication position to its non-communication position by a distance L1 in the vertical direction, as shown in FIG.","7.From this state, an operator pulls the process cartridge 17M rightward.","Through this action, the opening 83M of the first support part 78M disengages from the base part 126M on the urging member 120RM, and the opening 90M formed in the second support part 85M disengages from the base part 126M on the urging member 120LM, as shown in FIG.","8.As the process cartridge 17M continues to move rightward, the inner edge of the opening 83M defined in the first support part 78M slides downward and rightward along the sloped surface 128M of the urging member 120RM, and the inner edge of the opening 90M defined in the second support part 85M slides downward and rightward along the sloped surface 128M of the urging member 120LM.","Consequently, the process cartridge 17M itself moves diagonally downward and rightward.","As the process cartridge 17M continues to move rightward, the first sloped surface 84M on the first support part 78M contacts the engaging surface 125M on the urging member 120RM, while the second sloped surface 91M on the second support part 85M contacts the engaging surface 125M on the urging member 120LM.","At this time, the inner edge of the opening 83M defined in the first support part 78M separates from the sloped surface 128M on the urging member 120RM, and the inner edge of the opening 90M defined in the second support part 85M separates from the sloped surface 128M on the urging member 120LM.","As the process cartridge 17M continues to move rightward, the first sloped surface 84M slides diagonally downward and rightward along the engaging surface 125M formed on the urging member 120RM, and the second sloped surface 91M slides diagonally downward and rightward along the engaging surface 125M formed on the urging member 120LM.","Consequently, the process cartridge 17M itself moves diagonally downward and rightward and is placed on the center plate 52.This action interrupts communication between the opening 70M formed in the first conveying tube 77M and the opening 68M formed in the mounting unit 53M.","At this time, the process cartridge 17M is in its second position, as shown in FIG.","8.The process cartridge 17M is configured to move between the first position and the second position by a distance L2 smaller than the distance L1 in the vertical direction.","From this state, the process cartridge 17M is extracted from the main casing 2 through the opening 6 and opening 58.9.Image-Forming Operation When the toner cartridges 16Y, 16M, 16C, and 16K and process cartridges 17Y, 17M, 17C, and 17K are mounted in the main casing 2, as shown in FIG.","2, and an image-forming operation is initiated on the printer 1, the charging rollers 25Y, 25M, 25C, and 25K is configured to apply a uniform positive charge to the surfaces of the corresponding photosensitive drums 24Y, 24M, 24C, and 24K, as illustrated in FIG.","1.Subsequently, the scanning unit 15 exposes the surfaces of the photosensitive drums 24Y, 24M, 24C, and 24K by irradiating laser beams with high-speed scanning, thereby forming electrostatic latent images based on image data on the surfaces of the corresponding photosensitive drums 24Y, 24M, 24C, and 24K.","Incidentally, in each of the toner cartridges 16Y, 16M, 16C, and 16K, when the light-receiving element 112 receives light from the corresponding light-emitting element 111 (that is, when the level of toner in the second conveying tube 98 has not yet reached up to a position detectable by the detector 110), the first agitator 141 in each toner cartridge 16 is configured to rotate to convey toner from the corresponding large accommodating chamber 138 into the corresponding small accommodating chamber 139, as illustrated in FIG.","2.The second agitator 142 in the corresponding small accommodating chamber 139 also rotates to introduce toner from the small accommodating chamber 139 into the input tube 66 via the corresponding openings 72 and 68.The toner introduced into the input tube 66 moves through the first conveying tube 77 and second conveying tube 98 of the corresponding process cartridge 17.When the light-receiving element 112 no longer receives light from the corresponding light-emitting element 111 (that is, when a sufficient amount of the toner has been introduced into the second conveying tube 98), the printer 1 stops driving the first agitator 141 and second agitator 142 of the corresponding toner cartridge 16.Thus, the toner can be maintained at a low level in the second conveying tubes 98Y, 98M, 98C, and 98K, and therefore the level of the toner can be prevented from rising higher to reach the openings 70Y, 70M, 70C, and 70K in the first conveying tubes 77Y, 77M, 77M and 77C.","As illustrated in FIG.","1, the unit screws 30Y, 30M, 30C, and 30K subsequently convey the toner from right to left in the developing-unit frames 26Y, 26M, 26C, and 26K while supplying the toner onto the supply rollers 28Y, 28M, 28C, and 28K.","The toner supplied to the supply rollers 28Y, 28M, 28C, and 28K is in turn supplied onto the developing rollers 27Y, 27M, 27C, and 27K, at which time the toner is positively tribocharged between the supply rollers 28Y, 28M, 28C, and 28K and the corresponding developing rollers 27Y, 27M, 27C, and 27K.","As the developing rollers 27Y, 27M, 27C, and 27K rotate, the thickness of the toner supplied onto the developing rollers 27Y, 27M, 27C, and 27K is regulated by the thickness-regulating blades 29Y, 29M, 29C, and 29K so that a toner layer of uniform thickness is carried on the surface of each of the developing rollers 27Y, 27M, 27C, and 27K.","The positively charged toner carried on the surfaces of the developing rollers 27Y, 27M, 27C, and 27K is subsequently supplied to the electrostatic latent images formed on the surfaces of the respective photosensitive drums 24Y, 24M, 24C, and 24K as the photosensitive drums 24Y, 24M, 24C, and 24K rotate.","In this way, toner images are formed through reverse development on the surfaces of the photosensitive drums 24Y, 24M, 24C, and 24K.","Next, while the intermediate transfer belt 36 circulates, the photosensitive drums 24Y, 24M, 24C, and 24K transfer the toner images in their corresponding colors onto the intermediate transfer belt 36 in a primary transfer process.","In the meantime, the first pick-up roller 12 picks up and separates the sheets accommodated in the first sheet tray 9 and conveys the sheets one at a time and at a prescribed timing along the first sheet-feeding path 181 to the position between the intermediate transfer belt 36 and the secondary transfer roller 32.As each sheet passes between the intermediate transfer belt 36 and the secondary transfer roller 32, the toner image carried on the intermediate transfer belt 36 is transferred onto the sheet in a secondary transfer process.","Thereafter, heat and pressure are applied to the sheet in the fixing unit 19 as the sheet passes between the heat roller 41 and the pressure roller 42, thereby thermally fixing the toner image to the sheet.","After the toner image has been thermally fixed to the sheet in the fixing unit 19, the sheet is guided by the guide 45 oriented in the discharge position and is discharged into the discharge tray 43.Here, if sheets have been loaded in the second sheet tray 10, the second pick-up roller 13 picks up and separates the sheets in the second sheet tray 10 and conveys the sheets one at a time and at a prescribed timing along the second sheet-feeding path 182 to the position between the intermediate transfer belt 36 and secondary transfer roller 32.Further, when images are being formed on both surfaces of the sheet, the sheet is guided along the guide 45 oriented in the reverse position after a toner image has been thermally fixed to one side of the sheet in the fixing unit 19, and the sheet enters between the reversing rollers 44.By reversing their rotation, the reversing rollers 44 convey the sheet back downward into the main casing 2 along a U-shaped path that guides the sheet back to the position between the intermediate transfer belt 36 and the secondary transfer roller 32 in order that an image can be formed on the back side of the sheet.","Once the image has been formed on the back side of the sheet and thermally fixed to the sheet in the fixing unit 19, the sheet is guided along the guide 45, now oriented in the discharging position, and is discharged into the discharge tray 43.10.Cleaning Operation In the meantime, the drum cleaning blades 96Y, 96M, 96C, and 96K scrape off waster toner remaining on the corresponding photosensitive drums 24Y, 24M, 24C, and 24K.","The waste toner is collected in the drum cleaning frames 95Y, 95M, 95C, and 95K.","The drum cleaning screws 97Y, 97M, 97C, and 97K convey this waste toner rightward in the drum cleaning frames 95Y, 95M, 95C, and 95K.","As shown in FIG.","2, the waste toner being conveyed through the drum cleaning frames 95Y, 95M, 95C, and 95K flows into the connector tubes 172Y, 172M, 172C, and 172K through the discharge tubes 100Y, 100M, 100C, and 100K.","Thereafter, the conveying screw 164 conveys the waste toner diagonally downward and rearward in the conveying cylindrical part 171 to the third conveying tube 165.The waste toner falls down through the third conveying tube 165 and is collected in the waste toner container 166.As shown in FIG.","1, the belt-cleaning blade 152 scrapes residual toner off the intermediate transfer belt 36 so that the toner drops into the belt-cleaning frame 151.The belt-cleaning screw 153 then conveys the waste toner rightward in the belt-cleaning frame 151.The waste toner being conveyed in the belt-cleaning frame 151 flows into the conveying cylindrical part 171 through the first conveying tube 161 shown in FIG.","2.The waste toner is subsequently conveyed diagonally downward and rearward in the conveying cylindrical part 171 by the conveying screw 164 and flows into the third conveying tube 165.The waste toner is discharged from the third conveying tube 165 and collected in the waste toner container 166.To remove the waste toner container 166 from the main casing 2, the operator places the cover 64 in the open position and pulls the waste toner container 166 out of the main casing 2 through the access opening 63.At this time, the shutter 178 closes the opening 177 formed in the waste toner container 166, and the shutter 176 closes the opening 200 at the bottom end of the third conveying tube 165.11.Operational and Technical Advantages of the First Embodiment (1) In the printer 1 of the embodiment described above, the toner cartridges 16Y, 16M, 16C, and 16K can be mounted in and removed from the main casing 2 in the left-right direction through the corresponding openings 59Y, 59M, 59C, and 59K, as shown in FIG.","7.Further, the process cartridges 17Y, 17M, 17C, and 17K can be mounted in and removed from the main casing 2 in the left-right direction through the openings 6 and 58, as shown in FIG.","8.Hence, the toner cartridges 16Y, 16M, 16C, and 16K and process cartridges 17Y, 17M, 17C, and 17K can be independently mounted in and removed from the main casing 2 in the left-right direction.","When the process cartridges 17Y, 17M, 17C, and 17K are mounted in the main casing 2, as shown in FIG.","6, the urging members 120RY, 120RM, 120RC and 120RK and the urging members 120LY, 120LM, 120LC, and 120LK urge the corresponding process cartridges 17Y, 17M, 17C, and 17K toward the first positioning part 61 and the second positioning part 62.Thus, the process cartridges 17Y, 17M, 17C, and 17K are positioned such that toner supplied from the toner cartridges 16Y, 16M, 16C, and 16K can be received through the corresponding openings 70Y, 70M, 70C, and 70K.","Therefore, the toner supplied from the toner cartridges 16Y, 16M, 16C, and 16K can be reliably supplied to and received in the process cartridges 17Y, 17M, 17C, and 17K.","(2) As shown in FIG.","6, the urging members 120RY, 120RM, 120RC and 120RK and the urging members 120LY, 120LM, 120LC, and 120LK are positioned to the left of the openings 70Y, 70M, 70C, and 70K formed in the first conveying tubes 77Y, 77M, 77C, and 77K.","Accordingly, this construction can prevent interference between the urging members 120RY, 120RM, 120RC and 120RK and urging members 120LY, 120LM, 120LC, and 120LK and the openings 70Y, 70M, 70C, and 70K during mounting and removal of the process cartridges 17Y, 17M, 17C, and 17K relative to the main casing 2.","(3) Further, the urging members 120RY, 120RM, 120RC and 120RK are disposed to the right of the first positioning part 61, as shown in FIG.","6.Accordingly, the space in the printer 1 is effectively utilized when laying out the urging members 120RY, 120RM, 120RC and 120RK.","(4) Further, as shown in FIG.","6, the first positioning part 61 and second positioning part 62 are arranged further leftward than the openings 70Y, 70M, 70C, and 70K formed in the first conveying tubes 77Y, 77M, 77C, and 77K.","This arrangement can prevent interference between the first positioning part 61 and second positioning part 62 and the openings 70Y, 70M, 70C, and 70K when the process cartridges 17Y, 17M, 17C, and 17K are mounted in or removed from the main casing 2.","(5) As shown in FIG.","3, the process cartridges 17Y, 17M, 17C, and 17K are respectively provided with the drum-unit frames 23Y, 23M, 23C, and 23K and developing-unit frames 26Y, 26M, 26C, and 26K.","Further, the openings 70Y, 70M, 70C, and 70K are respectively formed in the drum-unit frames 23Y, 23M, 23C, and 23K.","Accordingly, the openings 70Y, 70M, 70C, and 70K can be arranged in fixed positions, even when the developing-unit frames 26Y, 26M, 26C, and 26K pivot relative to the drum-unit frames 23Y, 23M, 23C, and 23K.","Thus, the toner supplied from the toner cartridges 16Y, 16M, 16C, and 16K can be reliably received through the openings 70Y, 70M, 70C, and 70K.","(6) As shown in FIG.","3, the first conveying tubes 77Y, 77M, 77C, and 77K are connected to the second conveying tubes 98Y, 98M, 98C, and 98K on the right side of the first side plates 75Y, 75M, 75C, and 75K.","In other words, the first conveying tubes 77Y, 77M, 77C, and 77K are connected to the second conveying tubes 98Y, 98M, 98C, and 98K

prevents the need to enlarge the process cartridges 17Y, 17M, 17C, and 17K in the front-rear and vertical directions.","(7) As shown in FIG.","6, the first conveying tubes 77Y, 77M, 77C, and 77K at least partially overlap the corresponding urging members 120RY, 120RM, 120RC and 120RK in a front-rear projection.","Accordingly, the space required for arranging the urging members 120RY, 120RM, 120RC and 120RK and the first conveying tubes 77Y, 77M, 77C, and 77K in the printer 1 can be reduced.","(8) As shown in FIG.","3, the developing-unit frames 26Y, 26M, 26C, and 26K can pivot about the rotational shaft 74K relative to the drum-unit frames 23Y, 23M, 23C, and 23K, respectively.","Hence, by pivoting the developing-unit frames 26Y, 26M, 26C, and 26K relative to the drum-unit frames 23Y, 23M, 23C, and 23K, the developing-unit frames 26Y, 26M, 26C, and 26K can be separated from the drum-unit frames 23Y, 23M, 23C, and 23K, and the developing rollers 27Y, 27M, 27C, and 27K can be

first conveying tube 77 and second conveying tube 98 of the corresponding process cartridge 17.When the light-receiving element 112 no longer receives light from the corresponding light-emitting element 111 (that is, when a sufficient amount of the toner has been introduced into the second conveying tube 98), the printer 1 stops driving the first agitator 141 and second agitator 142 of the corresponding toner cartridge 16.Thus, the toner can be maintained at a low level in the second conveying tubes 98Y, 98M, 98C, and 98K, and therefore the level of the toner can be prevented from rising higher to reach the openings 70Y, 70M, 70C, and 70K in the first conveying tubes 77Y, 77M, 77M and 77C.\",\n \"As illustrated in FIG.\",\n \"1, the unit screws 30Y, 30M, 30C, and 30K subsequently convey the toner from right to left in the developing-unit frames 26Y, 26M, 26C, and 26K while supplying the toner onto the supply rollers 28Y, 28M, 28C, and 28K.\",\n \"The toner supplied to the supply rollers 28Y, 28M, 28C, and 28K is in turn supplied onto the developing rollers 27Y, 27M, 27C, and 27K, at which time the toner is positively tribocharged between the supply rollers 28Y, 28M, 28C, and 28K and the corresponding developing rollers 27Y, 27M, 27C, and 27K.\",\n \"As the developing rollers 27Y, 27M, 27C, and 27K rotate, the thickness of the toner supplied onto the developing rollers 27Y, 27M, 27C, and 27K is regulated by the thickness-regulating blades 29Y, 29M, 29C, and 29K so that a toner layer of uniform thickness is carried on the surface of each of the developing rollers 27Y, 27M, 27C, and 27K.\",\n \"The positively charged toner carried on the surfaces of the developing rollers 27Y, 27M, 27C, and 27K is subsequently supplied to the electrostatic latent images formed on the surfaces of the respective photosensitive drums 24Y, 24M, 24C, and 24K as the photosensitive drums 24Y, 24M, 24C, and 24K rotate.\",\n \"In this way, toner images are formed through reverse development on the surfaces of the photosensitive drums 24Y, 24M, 24C, and 24K.\",\n \"Next, while the intermediate transfer belt 36 circulates, the photosensitive drums 24Y, 24M, 24C, and 24K transfer the toner images in their corresponding colors onto the intermediate transfer belt 36 in a primary transfer process.\",\n \"In the meantime, the first pick-up roller 12 picks up and separates the sheets accommodated in the first sheet tray 9 and conveys the sheets one at a time and at a prescribed timing along the first sheet-feeding path 181 to the position between the intermediate transfer belt 36 and the secondary transfer roller 32.As each sheet passes between the intermediate transfer belt 36 and the secondary transfer roller 32, the toner image carried on the intermediate transfer belt 36 is transferred onto the sheet in a secondary transfer process.\",\n \"Thereafter, heat and pressure are applied to the sheet in the fixing unit 19 as the sheet passes between the heat roller 41 and the pressure roller 42, thereby thermally fixing the toner image to the sheet.\",\n \"After the toner image has been thermally fixed to the sheet in the fixing unit 19, the sheet is guided by the guide 45 oriented in the discharge position and is discharged into the discharge tray 43.Here, if sheets have been loaded in the second sheet tray 10, the second pick-up roller 13 picks up and separates the sheets in the second sheet tray 10 and conveys the sheets one at a time and at a prescribed timing along the second sheet-feeding path 182 to the position between the intermediate transfer belt 36 and secondary transfer roller 32.Further, when images are being formed on both surfaces of the sheet, the sheet is guided along the guide 45 oriented in the reverse position after a toner image has been thermally fixed to one side of the sheet in the fixing unit 19, and the sheet enters between the reversing rollers 44.By reversing their rotation, the reversing rollers 44 convey the sheet back downward into the main casing 2 along a U-shaped path that guides the sheet back to the position between the intermediate transfer belt 36 and the secondary transfer roller 32 in order that an image can be formed on the back side of the sheet.\",\n \"Once the image has been formed on the back side of the sheet and thermally fixed to the sheet in the fixing unit 19, the sheet is guided along the guide 45, now oriented in the discharging position, and is discharged into the discharge tray 43.10.Cleaning Operation In the meantime, the drum cleaning blades 96Y, 96M, 96C, and 96K scrape off waster toner remaining on the corresponding photosensitive drums 24Y, 24M, 24C, and 24K.\",\n \"The waste toner is collected in the drum cleaning frames 95Y, 95M, 95C, and 95K.\",\n \"The drum cleaning screws 97Y, 97M, 97C, and 97K convey this waste toner rightward in the drum cleaning frames 95Y, 95M, 95C, and 95K.\",\n \"As shown in FIG.\",\n \"2, the waste toner being conveyed through the drum cleaning frames 95Y, 95M, 95C, and 95K flows into the connector tubes 172Y, 172M, 172C, and 172K through the discharge tubes 100Y, 100M, 100C, and 100K.\",\n \"Thereafter, the conveying screw 164 conveys the waste toner diagonally downward and rearward in the conveying cylindrical part 171 to the third conveying tube 165.The waste toner falls down through the third conveying tube 165 and is collected in the waste toner container 166.As shown in FIG.\",\n \"1, the belt-cleaning blade 152 scrapes residual toner off the intermediate transfer belt 36 so that the toner drops into the belt-cleaning frame 151.The belt-cleaning screw 153 then conveys the waste toner rightward in the belt-cleaning frame 151.The waste toner being conveyed in the belt-cleaning frame 151 flows into the conveying cylindrical part 171 through the first conveying tube 161 shown in FIG.\",\n \"2.The waste toner is subsequently conveyed diagonally downward and rearward in the conveying cylindrical part 171 by the conveying screw 164 and flows into the third conveying tube 165.The waste toner is discharged from the third conveying tube 165 and collected in the waste toner container 166.To remove the waste toner container 166 from the main casing 2, the operator places the cover 64 in the open position and pulls the waste toner container 166 out of the main casing 2 through the access opening 63.At this time, the shutter 178 closes the opening 177 formed in the waste toner container 166, and the shutter 176 closes the opening 200 at the bottom end of the third conveying tube 165.11.Operational and Technical Advantages of the First Embodiment (1) In the printer 1 of the embodiment described above, the toner cartridges 16Y, 16M, 16C, and 16K can

process cartridges 17Y, 17M, 17C, and 17K toward the first positioning part 61 and the second positioning part 62.Thus, the process cartridges 17Y, 17M, 17C, and 17K are positioned such that toner supplied from the toner cartridges 16Y, 16M, 16C, and 16K can be received through the corresponding openings 70Y, 70M, 70C, and 70K.\",\n \"Therefore, the toner supplied from the toner cartridges 16Y,

least two different criteria.","A first criterion relates to the angles of incidence (or illumination directions) provided by the effective source in view of the particular sub-pattern to be exposed, which is characterized by first features extending in a first direction and spaced apart essentially periodically at the predominant periodicity length P in the second direction.","Under these conditions, an optimized illumination (optimized for contrast in an appropriate focus range determined by the depth of focus (DOF)) would generally provide only those illumination directions which could contribute to the imaging process for the detail of interest, which is characterized by periodicity length P.

in the pupil of the illumination system.","Those areas including all useful illumination directions (to obtain maximum contrast) generally define areas in the pupil surface having a lenticular shape

dipole illumination typically use only a small fraction of the illumination angles which might theoretically be used to form a high-contrast image with two-beam interference.","For example, small poles with circular shape or poles having the shape of a segment of an annulus have been used.","Whereas those small poles of dipole illumination may be acceptable from a contrast point of view if only “useful” illumination directions are used, drawbacks in respect to overall performance may result if light energy is concentrated on correspondingly small areas on optical surfaces at or close to

system.","Such issues can be addressed and at least partly avoided by providing illumination modes including at least one substantially dipolar intensity distribution with poles having optimized pole

shown in different figures are designated with the same reference identifications, where appropriate.","In optical lithography it is known to use off-axis illumination, which enables smaller features to be faithfully imaged.","With this technique, a mask providing the patterned structure (pattern) is illuminated at oblique (non-perpendicular) angles such that process latitude is improved by increasing the depth of focus and/or such that contrast is improved.","FIG.","1 illustrates this principle in which a beam B of radiation is incident on a mask M carrying a pattern PAT at an opening angle γ inclined to the optical axis OA, which is conventionally vertical.","The incident beam B is diffracted by features of the pattern PAT on the mask M, which are to be imaged onto the wafer W coated by a layer of photoresist RES.","The zeroth and two first-order-diffracted beams (0, ±1) are shown in FIG.","1.Improved performance can be achieved when, for example, at least part of the zeroth order and one of the first orders, which are coherent, are captured by the projection objective PO and used to form the image on the wafer W. The smaller the pitch P (or periodicity length) of features of the pattern on the mask M, the larger the diffraction angle β will be according to β=λ/P, where λ is the nominal operating wavelength of radiation in beam B.","If the size of the features decreases and/or their density increases too much, there will come a point at which the pupil of the projection objective PO can no longer capture more than one diffracted order.","In practical systems there will be a range of opening angles γ which determines the partial coherence of the light source and thus is important to the figures of merit of the exposure process, such as exposure latitude, depth of focus and proximity effects.","The distribution of opening angles γ can be visualized by considering the intensity distribution of the effective radiation source (effective source) or equivalently the intensity distribution in the plane of a pupil of the projection objective.","FIGS.","2A-2D show representative examples.","FIG.","2A illustrates a simple on-axis illumination mode characterized by the parameter σ shown by an arrow in the figure.","Values of σ (often referred to as coherence factor) are conventionally quoted as the ratio of the radius of the illumination intensity disc (hatched) to the radius of the pupil and therefore take a value between 0 and 1.FIG.","2B shows an annular illumination mode in which the intensity distribution of the source is confined to an annulus to limit the range of angles of incidence of the off-axis illumination, considering that the spatial intensity distribution at the pupil plane is related to the angular distribution at the mask plane, which is a Fourier transform plane to the pupil plane.","The annulus may be characterized by the values σi and σo, which are the ratios of its inner and outer radii to the radius of the pupil.","FIG.","2C illustrates the intensity distribution of the quadrupole illumination mode, the use of which sometimes gives improved imaging results to the use of annular or coherent modes.","Conventionally, in using such a quadrupole configuration, it is assumed that the patterned structure of the mask to be projected includes sub-patterns of orthogonal lines along x and y axes and the illumination is oriented such that each of the four poles is situated in a respective one of the four quadrants defined by these x and y axes and at their point of intersection.","In specific applications it has been found that superior performance can be obtained using dipolar illumination modes.","FIG.","2D shows an example of the dipolar illumination intensity distribution for a dipole mode.","The two poles POLE1, POLE2 of this mode are located off the optical axis OA of the imaging system.","For illustrative purposes, the two poles illustrated in FIG.","2D are said to lie along the x axis (second direction) and may be optimal for imaging lines extending parallel to the y axis (first direction), i.e.","perpendicular to the pole orientation axis POA joining the two poles.","Sometimes the x and y axis are referred to as horizontal and vertical, respectively, but these terms typically do not bear any relation to the orientation of the machine.","As illustrated in FIG.","2D the pole shape of the poles POLE1, POLE2 in conventional systems may correspond to an azimuthal section of an annulus.","Due to the desire that the first diffraction order should pass completely through the aperture of the projection objective to obtain maximum contrast, limitations result for the radial width Δσ=σo−σi of the poles and for the azimuthal width (width in circumferential direction) of the poles defined by the pole angle Θ.","With dipole illumination, the effective light source is confined to two poles, in order to create the conditions for two-beam imaging with theoretical ideal contrast.","FIG.","3 illustrates schematically a projection exposure system configured for dipole illumination mode.","Primary radiation provided by a primary light source LS is transformed by an illumination system ILL to provide illumination radiation incident on a mask M bearing a pattern PAT.","The radiation is diffracted by pattern PAT and forms projection radiation propagating through the projection objective PO, which images the pattern of the mask onto the substrate, which is a wafer W coated with a resist layer RES in the exemplary embodiment.","The illumination system ILL includes a pupil shaping unit PSU to create an effective source ES formed by a predefined intensity distribution at a pupil plane PILL of the illumination system, where the predefined intensity distribution is a dipole illumination characterized by two lenticular poles POLE1 and POLE2.The pupil plane PILL, where the effective source ES is formed, is a Fourier transform surface with respect to the object surface of the projection objective PO, where the mask M is situated.","Therefore, the spatial distribution of light intensity of the effective source ES determines an angular distribution of illumination radiation incident on the mask M. A condenser system CS is provided to perform the Fourier transformation.","The pupil surface PPO of the projection objective is optically conjugated to the pupil surface PILL of the illumination system.","Therefore, in the absence of a mask, a spatial intensity distribution equivalent to the intensity distribution at the effective source ES may be formed in the pupil surface PPO of the projection objective.","Where a mask bearing a pattern is inserted between the illumination system and the projection objective, the intensity distribution in the pupil plane PPO of the projection objective also contains diffraction information corresponding to the properties of the mask pattern PAT.","FIG.","4 illustrates schematically a circular pupil PPO of a projection objective having unit radius (length=1) corresponding to the utilized image-side numerical aperture NA at imaging conditions beyond the coherent resolution limit of a periodic pattern of mutually parallel lines running in a first direction (y direction) having periodicity length (pitch) P in a second direction (x direction).","A symmetric two-beam interference imaging condition is assumed, where a first diffraction order (+1 or −1) coincides with the zeroth order (0).","In this representation, all illumination directions which contribute constructively to two-beam interference correspond to pupil positions lying within the lenticular (lens-shaped) regions LR at opposite edges of the pupil in the x direction.","Those lenticular regions (also denoted as “planar circular two-angles” result from a partial overlap of circles of equal size corresponding to neighbouring diffraction orders.","A distance d between the centers of the lenticular regions is determined by d=λ/(P*NA).","The angular width of the lenticular area (width in circumferential direction) may be defined by a pole angle θ between the opposing corners of the area in the y direction, where pole angle θ is twice the pole half angle α (i.e.","θ=2*α).","The size of the lenticular area, i.e.","the area AOPT of the hatched lenticular region LR in FIG.","4, may be calculated as AOPT=θ−sin(θ) with cos(α)=d/2=λ/(2*P*NA).","It is contemplated that a maximum contrast is possible if all illumination directions corresponding to pupil positions within the lenticular regions LR are used.","The size AOPT of the lenticular regions may be calculated based on the following considerations explained now in connection with FIG.","4.The area AOPT is four times the difference between the area AS of the circular sector with sector angle α, and the area AABC of triangle ABC indicated in FIG.","4.The difference area AS-AABC is hatched darkly in FIG.","4.Calculating the angles in radians, the sector area AS is calculated as follows: AS=(α/2π)·π·r2, where r=1 is the unit radius of the pupil.","Therefore, AS=(α/2π)·π=α/2.With distance A−C=cos (α) and distance B−C=sin (α) the area AABC of the triangle calculate as: AABC=(sin (α)·cos (α))/2.Further considering that 2·sin (α)·cos (α)=sin (2·α), the area AOPT of the lenticular region LR calculates as follows: A OPT = 4 · ( A S - A ABC ) = 4 · ( α / 2 - ( sin ( α ) · cos ( α ) ) / 2 ) = 2 · α - sin ( 2 · α ) = θ - sin ( θ ) An illumination pole having the size and shape of a desirable (e.g., optimum) lenticular region LR may be characterized by a pole width PW measured between an inner and an outer pole edge in a direction parallel to the pole orientation axis POA, and a pole height PH measured between pole edges in a direction perpendicular to the pole orientation axis, i.e.","in y direction (see FIG.","5A).","Defining a pole dimension ratio PDR as the aspect ratio between pole PH height and pole width PW according to PDR=PH/PW, for the lenticular regions PDROPT=sin(α)/(1−cos(α)).","In conventional systems, only a fraction of those illumination directions is normally used.","For illustration purposes, FIG.","4 shows conventional poles CP having a shape corresponding to an azimuthal section of an annulus within the lenticular regions LR.","Limitations regarding radial width Δσ and pole angle result from the desire that the first diffraction order should fall completely within the aperture of the objective to obtain maximum contrast.","As evident from FIG.","4, the area of the conventional poles CP is significantly smaller than the area AOPT of the lenticular zones which could be used for the imaging process at good (e.g., optimum) contrast.","For example, the size of the conventional poles may be 50% or less of the area AOPT.","The pole dimension ratio PDR of a conventional pole usually differs significantly from the pole dimension ratio PDROPT defined above.","For example, a circular pole would correspond to PDR=1.The annular segment shaped conventional poles CP depicted schematically in FIG.","4 may have varying pole dimension ratio depending on the selected values for Δσ and pole angle.","Generally, as the pole height increases, the pole width will decrease, and vice versa.","Now consider a lens or another optical element having an optical surface at or close to the pupil surface of the projection objective, where light intensity is concentrated at the edge of the lens surface in regions corresponding to the poles of the dipole illumination.","Studies have shown that effects of lens heating may cause characteristic deformations of wavefronts passing the projection objective due to local deformation of the lenses and/or due to localized radiation-induced changes of refractive index.","For example, where a dipolar intensity distribution is used, the local deformation of lenses or other optical elements and associated wavefront deformations may be dominated by astigmatic contributions.","In the following a number of embodiments are described where a multipolar illumination mode includes at least one substantially dipolar intensity distribution having two illumination poles, where the pole area APOLE of poles is selected to be very close to or equal to the pole area AOPT defined above.","Negative effects caused by localized lens heating may be reduced significantly when compared to using conventional poles.","FIGS.","5A-5C illustrate where the poles POLE 1 and POLE 2 of the dipolar intensity distribution each have a lenticular pole shape defined by two convexly curved edges having opposite sense of curvature and centers of curvature essentially on a line parallel to the pole orientation axis POA.","In FIG.","5A the size and shape of the poles is adjusted such that the poles exactly fit the lenticular region LR corresponding to the given pitch P of the sub-pattern to be printed.","The conditions APOLE=AOPT and PDRPOLE=PDROPT hold for the pole area and pole dimension ratio, respectively.","FIG.","5B shows an example where all light intensity is concentrated in poles POLE1, POLE2 slightly smaller than the lenticular area by about 10%.","Although not all illumination directions theoretically contributing to constructive interference are used in this setting, the intensity of the poles is still distributed over a relatively large area on optical surfaces near pupil surfaces to eliminate or alleviate lens heating problems.","In FIG.","5C the size of the poles POLE1, POLE2 is slightly larger than the pole area AOPT of poles such that a small fraction of illumination directions falls outside the pupil, thereby not contributing to imaging, and some illumination angles smaller than the lowest limit of the optimum angular distribution according to FIG.","4 are also present.","As light energy is distributed over relatively large areas around the poles, lens heating problems may be smallest in FIG.","5C with potential trade-offs in attainable contrast.","Optimum compromise settings may be evaluated by simulation or test exposures.","FIGS.","6A-6B illustrate schematically one option to generate biconvex, lenticular (lens-shaped shaped) illumination poles as described above in a modified conventional illumination system configured to generate illumination poles having the shape of a segment of an annulus.","Illumination systems as described e. g. in U.S. Pat.","No.","6,452,662 B2 may be used and modified for that purpose.","The disclosure of U.S. Pat.","No.","6,452,662 B2 and U.S. Pat.","No.","6,855,486 B1 regarding constructive details of illumination systems capable of generating segment shaped pairs of poles are incorporated herein by reference.","The adjustable optical elements of the pupil shaping unit of the illumination system are first set to generate, in a pupil surface of the illumination system, a dipolar intensity distribution having two basic poles BP1 and BP2, each having the shape of a segment of an annulus where the outer radius is set to σO=1 and the width of the annular segment is adjusted such that Δσ corresponds to the desired pole width PW of the desired lenticular pole.","The pole angle θ is set to correspond to the desired pole angle θ of the lenticular pole (FIG.","6A).","It is to be noted that conventional systems may need to be modified with respect to the variation width of adjustable elements to allow for those dimensions of the annular segment shaped poles, which may be larger than poles in the conventional system in both the circumferential and the radial direction.","The illumination system includes a blocking device BD (FIG.","6B) at or close to the pupil surface of the illumination system where the effective source is generated, or at or close to a pupil surface optically conjugate thereto.","The blocking device in this embodiment is designed to block those areas at the inner edge of the annulus segment shaped poles which lie outside the lenticular region desired for the pole shape.","For that purpose, the blocking device may take the general butterfly shape schematically shown in FIG.","6B having “wings” extending in azimuthal direction over an angle θ corresponding to the pole angle, and comprising outer edges concavely curved inwards towards the center of the blocking device to define the inner edge of the lenticular pole.","Those areas actually blocked by the blocking device are drawn with diagonal hatching in FIG.","6A.","When the blocking device is inserted into the appropriate position, the resulting effective light source includes two lenticular poles POLE1 and POLE2 having the pole area AOPT or a slight variation therefrom as described above.","An exchanging device allowing to exchange blocking devices having different layout may be provided to allow variation of dimensions of the lenticular poles.","Also, a blocking device may be designed to be variable, for example by providing a number of smaller blades arranged in the manner of a fan to allow varying the pole angle θ as desired.","The blocking device may also be formed by an opaque coating on a transparent optical element, such as a plate, which may be exchangeable.","In FIGS.","7A-7B the poles of the dipolar intensity distribution have a parallelogram pole shape defined by a non-rectangular parallelogram having a shorter diagonal D2 and a longer diagonal D1, the shorter diagonal extending substantially parallel to a line parallel to the pole orientation axis POA.","FIGS.","7A and 7B each show the lenticular regions LR corresponding to the optimum size and shape of poles adapted to a sub-pattern having predominant pitch P. In FIG.","7A, each of the poles POLE1 and POLE2 of the dipolar intensity distribution has the shape of a rhombus, i. e. the shape of an equilateral quadrangle arranged mirror symmetric to the pole orientation axis POA.","The biconvex, diamond shaped poles are fit into the optimum sized lenticular region LR such that their longer diagonal D1 (extending in y-direction) defines the pole height PH, whereas the shorter diagonal D2 extending between the inner and outer edge of the pole in the second direction (x-direction) corresponds to the pole width PW.","The area of each of the rhombohedral poles POLE1, POLE2 is APOLE=(D1*D2)/2, which is smaller than the area AOPT of the optimum sized lenticular region.","The difference in area, ΔA, may be calculated according to ΔA=2*α·sin (2*α)−4*sin (α)*(1−cos (α)).","As exemplified in FIG.","7B, it is not necessary to fit the diamond shaped poles exactly into the optimum lenticular region LR.","For example, the rhombohedral poles may be slightly larger such that tips of the rhombohedron in the first direction and/or in the second direction may extend beyond the outer limits of the ideal lenticular region LR.","Also, the pole dimension ration PH/PW may deviate from the optimum value, thereby resulting in slightly narrower or wider diamond shaped poles.","The deviation may be up to about 10%, for example.","Although some loss of contrast might occur, the oversizing of the rhombohedral poles allows to distribute light energy over larger areas at the edges of optical elements near to a pupil, thereby eliminating or decreasing problems associated with localized lens heating.","FIG.","8 shows a meridional section of an illumination system ILL configured to be used in a projection exposure step-and-scan apparatus.","The illumination system includes a plurality of optical elements constructed and arranged to receive primary radiation emitted from a primary light source LS and to generate illumination radiation incident on a mask M bearing a pattern.","In the embodiment, the light source LS is an excimer laser emitting primary radiation having a nominal operation wavelength in the deep ultraviolet (DUV) spectral range, for example 193 nm.","Primary radiation exciting the light source LS forms a coherent radiation bundle having a small cross-section and low divergence, which corresponds to a small value of geometrical optical flux (etendue).","A number of optical elements following the light source LS form a variable pupil shaping unit PSU configured to generate a defined spatial intensity distribution corresponding to a selected illumination mode in a pupil surface PILL of the illumination system.","A partial system PS following the pupil surface PILL includes a number of optical elements configured to transform the two-dimensional intensity distribution present in the pupil surface PILL into a corresponding angular distribution of illumination radiation incident on the mask M. The partial system PS includes elements to homogenize the radiation and to sharply define the edges of an illumination field in the exit surface EX of the illumination system, which coincides with the object surface of a subsequent projection objective (see FIG.","3).","The pupil shaping unit PSU comprises, at an entry side thereof, a beam expansion unit EXP which expands the coherent radiation bundle received from the light source LS.","The beam expansion unit includes a number of refractive optical elements diverting the radiation such that the cross-section of the bundle is increased without altering the geometrical optical flux of the bundle.","After passing through the beam expansion unit EXP the projection radiation bundle impinges on a first optical raster element RE1 structured to increase divergence of the radiation bundle by introducing propagation angles according to a desired illumination mode.","In FIG.","8 this is schematically illustrated for an axial ray that is split into two diverging rays R1, R2 after the raster element RE1.The first raster element RE1 modifies the angular distribution of the radiation bundle and also increases the geometrical optical flux thereof.","The first raster element RE1 may be formed by a diffractive optical element (DOE) or by a refractive optical element (ROE), for example.","Various kinds of optical raster elements are possible, for example a micro-lens array in which micro-lenses are formed by Fresnel zone plates.","The first raster element RE1 may be a reflective raster element including an array of mirror segments oriented at different angles (multi-mirror array).","First raster element RE1 is arranged in a front focal plane FFP of a zoom/axicon module ZA which includes a zoom lens group Z providing a continuously variable magnification, and an axicon group AX comprising a pair of axicons AX1, AX2, one concave and one convex, whose separation can be varied continuously to allow adjusting a distance between the axicon surfaces between zero distance (contact between axicon surfaces) and preselected finite values.","The entire zoom/axicon module ZA is configured as a focal length optical system transforming an angular distribution of radiation in the front focal plane FFP into a desired two-dimensional (spatial) intensity distribution in the rear focal plane RFP, which coincides with the pupil surface PILL of the illumination system.","A field defining arrangement FD is positioned in the rear focal plane RFP of the zoom/axicon module ZA.","The field defining arrangement is configured to further introduce divergence into the radiation beam, thereby further enlarging the geometrical flux of the radiation beam.","The divergence introduced by the field defining arrangement FD is schematically represented by divergent rays downstream of the field defining arrangement.","Embodiments of field defining arrangements suitable for this purpose are disclosed, for example, in applicant's international application published as WO 2005/078522 A2, which is incorporated herein by reference in its entirety.","The diverging rays exiting the field defining arrangement FD enter an objective OB represented by a single condenser lens.","The objective OB is arranged within the illumination systems such that an entrance pupil plane of the objective OB coincides with the exit pupil surface of the zoom/axicon module.","The image plane of objective OB, which is a Fourier transform plane to the pupil PILL of the illumination system, is a field plane FP within the illumination system.","A reticle masking unit REMA acting as an adjustable field stop is positioned in the field plane FP to define the edges of the illumination field.","Details of embodiments may be taken, for example from WO 2005/078522 A2.An imaging objective RO is arranged between the field plane FP and the exit surface ES of the illumination system, where the mask M may be positioned and allows to image the intensity distribution present in the field plane FP onto the mask pattern.","FIGS.","9A-9b show schematically a detail of a first raster element RE1 configured to generate a substantially dipolar intensity distribution having two illumination poles each having the diamond shape discussed in context of FIG.","7.The raster element RE1 is formed by an array of raster segments RS arranged side by side in a mosaic arrangement to cover without interspaces the complete illuminated surface of the raster element RE1.Such arrangement allows to generate the dipolar intensity distribution essentially without blocking any parts of the beam so that there is no intensity loss involved in the generation of the dipolar intensity distribution.","The raster element RE1 can be formed by an array of refractive lens segments.","Each raster segment RS may be formed by a segment of a lens or a prism where an entry-side surface and an exit-side surface of the raster segment are oriented such that a desired redirection of radiation is caused by refraction at the segment surfaces as the radiation passes through the raster segment.","The rhombohedral shape of the raster segments RS determines the shape of the poles in the pupil surface PILL.","In FIG.","9A the raster segments are numbered “1” and “2” to illustrate which raster segments contribute to the illumination intensity in the two poles POLE1 and POLE2 shown in FIG.","9B.","The structure of the raster segments is adjusted to redirect at least a major portion of impinging radiation to the two poles.","As illustrated by dashed lines in some raster segments of FIG.","9A, the raster elements may also be segmented into other shapes, such as triangular raster segments, where the size and shape of the triangles are adapted to define, in combination, a rhombohedral area corresponding to the desired pole shape.","In some embodiments, the raster element RE1 may be designed as a diffractive computer generated hologram (CGH) assigning to each of the raster segments RS a diffractive structure effective to redirect light intensity present in a partial beam impinging on the raster segment into the associated pole.","The raster segments may have a shape differing from the shape of the desired poles, e.g.","a rectangular shape.","The diffractive structure may be formed on the surface of a transparent substrate, such as a plane plate made of fused silica or calcium fluoride.","The raster segments may also be formed of grooves etched into the surface to provide segments of a Fresnel lenses.","The depth and width of the grooves may be in the order of micrometers, for example.","Each raster segment may be in the order of millimeters in size and the entire array forming the raster element may have typical dimensions of one or a few centimeters.","The basic distribution of angles introduced by the raster element RE1 may be modified within the pupil shaping unit by setting the elements of the variable zoom lens group Z and/or the variable axicon group AX accordingly.","In one configuration, the separation between the axicon elements AX1 and AX2 is set to zero (contact between axicon surfaces) such that no radial redirection of light intensity is effected by the axicon group AX.","In other configurations, a defined separation may be set, which generally causes a central symmetric dilatation of the radiation intensity distribution, which may be useful in some cases.","Adjusting the magnification of the zoom lens group Z allows to adapt the illumination intensity distribution in the pupil surface PILL of the illumination system to different NA values in a homomorphous imaging step.","It is to be noted that the conditions for the pole area APOLE, pole height PH and pole width PW as defined above remain unchanged as long as P*NA=2 k1*λ=const.","Therefore, the area of the poles as well as the pole height and pole width may be considered as a function of parameter k1 alone, where k1<1 is a process dependent parameter that incorporates everything in a lithography process that is not wavelength or numerical aperture.","Generally, any process or system modification that allows improvements in resolution effectively reduces the k1 factor.","Diffraction-limited values are 0.25 for incoherent and 0.5 for coherent illumination, for example.","Where k1 stays essentially constant, sub-patterns with different predominant periodicity values P (pitches) may be illuminated using one and the same raster element RE1 by simply adjusting the appropriate NA value using the zoom lens group Z.","With other words: one type of raster element with fixed configuration, such as a diffractive optical element, may be sufficient for different processes defined by one particular k1 value (or a small variation of k1).","Different values for APOLE, PW and/or PH and different pole patterns may also be obtained by providing several different, interchangeable first raster elements.","An automatic changer may be used to exchange raster elements of different configuration in the illumination system.","In general, the pupil-shaping unit may include at least one optical modulation device configured to controllably change an angular distribution of radiation incident on the optical modulation device such that a desired intensity distribution is obtained in the pupil surface of the illumination system.","Although the optical modulation device may have a fixed configuration to obtain only one type of intensity distribution (which may be changeable by additional variable optical elements), it is possible that the optical modulation device has an array of individual elements configured to be driven individually to change the angular distribution of radiation incident on the individual elements.","The optical modulation device may include a controllable micro-mirror array, for example.","Various optical modulation devices which may be used when modified for that purpose are disclosed in applicant's international patent application published as WO 2005/026843 A2.The disclosure of this application is incorporated herein by reference.","FIGS.","10A-10B show diagrams illustrating, for an exemplary projection exposure systems, improvements that may be obtained if an optimized dipole setting is used instead of a conventional setting.","In the diagrams, pupil coordinates in terms of image-side numerical aperture NA are drawn in the abscissa.","The ordinates show values for the phase error value of the overall wavefront aberration.","The value “0” corresponding to the optical axis.","Each diagram shows an “x-cut” parallel to the x-axis (second direction) and an “y-cut” perpendicular thereto in the first direction.","An x-dipole (orientation of pole orientation axis along x-direction) is used for all experiments.","A dipole setting having poles with the shape of a segment of an annulus (compare e.g.","FIG.","2B) was used for the reference example of a conventional dipole setting CONV shown in FIG.","10A.","An x-dipole setting with lenticular poles with APOLE=AOPT was used for the experiment illustrated in FIG.","10B.","The x-cut in both experiments illustrates that the localized heating in the region of the poles generally aligned along the x-direction leads to relatively strong wavefront aberrations close to the outer edge of the pupil where the energetic centriods of the poles are positioned.","In contrast, essentially no wavefront aberration is caused on and close to the optical axis in the center of the pupil.","In the y-direction a relatively large variation of wavefront aberrations occurs superimposed onto a slight gradient from the upper edge to the lower edge of the pupil in this specific type of projection objective used for the experiment.","The general characteristics of the local distribution of wavefront aberrations caused by lens heating are quite similar in the experiment according to FIG.","10B.","Note, however, that the absolute amount of wavefront aberration caused by lens heating is reduced by about a factor two, i.e.","reduced to about 50% of the value for the conventional setting in the x-direction (different scales in the ordinates in FIG.","10A, in FIG.","10B).","This significant improvement is attributed to the fact that radiant energy present within the projection beam is distributed over larger areas at the position of the poles, whereby the energy distribution in smeared out over a larger area, thereby reducing associated lens heating effects on wavefront aberrations.","The effect is less pronounced in the y-direction.","In some embodiments, the multipolar illumination is a pure dipole illumination, where the intensity distribution in the pupil surface of the illumination system is formed by one substantially dipolar intensity distribution having exactly two illumination poles.","Such dipole illumination may be used, for example, to print periodic patterns with features essentially aligned in one direction only.","As a practical example, a layer of a highly integrated flash memory device may be strongly dominated by lines running in direction only.","Due to the relatively large pole height PH of the optimized pole areas those dipole illuminations are also useful to improve contrast of sub-patterns not running at the predominant direction, but at an angle thereto since the dipolar intensity distribution includes illumination directions significantly deviating from the direction defined by the pole orientation axis.","The multipolar illumination mode may include two substantially dipolar intensity distributions (“dipoles”) superimposed on each other, where the pole orientation axes of the dipoles are rotated relatively to each other, for example by 90°.","FIG.","11 depicts schematically the intensity distribution in the illumination pupil for a quadrupole illumination having two pairs of lenticular poles relatively rotated by 90° around the optical axis to form four lenticular poles, POLE1, POLE2, POLE3, POLE 4, where the pole orientation axis POAx of the first dipolar intensity distribution (forming poles POLE1 and POLE2) is oriented along the x-direction, whereas the pole orientation axis POAy of the second dipolar intensity distribution (forming poles POLE3 and POLE4) is oriented perpendicular thereto in the y-direction.","A bi-directional pattern having periodic features in x- and y-direction may be printed with high contrast for both directions.","The area of each of the poles corresponds approximately to the optimum area AOPT in this example.","As illustrated schematically in FIG.","12, the method and apparatus may also be used in exposure processes which do not exploit the full resolution potential of the projection exposure apparatus.","For example, a multi-polar illumination mode may be set for a pattern or sub-pattern having features spaced apart periodically at a predominant periodicity length P where the condition 0.7*λ/NA1 between a pole height PH and a pole width PW, where the pole width PW is measured between an inner edge and an outer

incidence (or illumination directions) provided by the effective source in view of the particular sub-pattern to be exposed, which is characterized by first features extending in a first direction and spaced apart essentially periodically at the predominant periodicity length P in the second direction.\",\n \"Under these conditions, an optimized illumination (optimized for contrast in an appropriate focus range determined by the depth of focus (DOF)) would generally provide only those illumination directions which could contribute to the imaging process for the detail of interest, which is characterized by periodicity length P. Where two-beam interference beyond the coherent resolution limit is desired to optimize resolution, the illumination directions allowing high contrast two-beam interference correspond to certain areas in the pupil of the illumination system.\",\n \"Those areas including all useful illumination directions (to obtain maximum contrast) generally define areas in the pupil surface having a lenticular shape resulting from an overlapping zone of two circles with equal unit radius having a distance d between the centers of the circles.\",\n \"Illumination directions corresponding to pupil locations outside these useful lens-shaped areas generally do not contribute to the desired two-beam interference and might in fact blur a resulting image.\",\n \"Those lenticular useful areas including all illumination directions contributing constructively to two-beam interference may be characterized by their size and correspond to a pole area (e.g., an optimum pole area) A OPT in a conjugated exit pupil of the projection optical system used for the exposure method.\",\n \"The second criterion regards the illumination angles actually used in an exposure process.\",\n \"It has been found that known systems employing dipole illumination typically use only a small fraction of the illumination angles which might theoretically be used to form a high-contrast image with two-beam interference.\",\n \"For example, small poles with circular shape or poles having the shape of a segment of an annulus have been used.\",\n \"Whereas those small poles of dipole illumination may be acceptable from a contrast point of view if only “useful” illumination directions are used, drawbacks in respect to overall performance may result if light energy is concentrated on correspondingly small areas on optical surfaces at or close to a pupil surface within the exposure system.\",\n \"Those local energy concentrations may cause or contribute to “lens heating” and associated time-dependent fluctuations of performance of the exposure system.\",\n \"Such issues can be addressed and at least partly avoided by providing illumination modes including at least one substantially

reference identifications, where appropriate.\",\n \"In optical lithography it is known to use off-axis illumination, which enables smaller features to be faithfully imaged.\",\n \"With this technique, a mask providing the patterned structure (pattern) is illuminated at oblique (non-perpendicular) angles such that process latitude is improved by increasing the depth of focus and/or such that contrast is improved.\",\n \"FIG.\",\n \"1 illustrates this principle in which a beam B of radiation is incident on a mask M carrying a pattern PAT at an opening angle γ inclined to the optical axis OA, which is conventionally vertical.\",\n \"The incident beam B is diffracted by features of the pattern PAT on the mask M, which are to be imaged onto the wafer W coated by a layer of photoresist RES.\",\n \"The zeroth and two first-order-diffracted beams (0, ±1) are shown in FIG.\",\n \"1.Improved performance can be achieved when, for example, at least part of the zeroth order and one of the first orders, which are coherent, are captured by the projection objective PO and used to form the image on the wafer W. The smaller the pitch P (or periodicity length) of features of the pattern on the mask M, the larger the diffraction angle β will be according to β=λ/P, where λ is the nominal operating wavelength of radiation in beam B.\",\n \"If the size of the features decreases and/or their density increases too much, there will come a point at which the pupil of the projection objective PO can no longer capture more than one diffracted order.\",\n \"In practical systems there will be a range of opening angles γ which determines the partial coherence of the light source and thus is important to the figures of merit of the exposure process, such as exposure latitude, depth of focus and proximity effects.\",\n \"The distribution of opening angles γ can be visualized by considering the intensity distribution of the effective radiation source (effective source) or equivalently the intensity distribution in the plane of a pupil of the projection objective.\",\n \"FIGS.\",\n \"2A-2D show representative examples.\",\n \"FIG.\",\n \"2A illustrates a simple on-axis illumination mode characterized by the parameter σ shown by an arrow in the figure.\",\n \"Values of σ (often referred to as coherence factor) are conventionally quoted as the ratio of the radius of the illumination intensity disc (hatched) to the radius of the pupil and therefore take a value between 0 and 1.FIG.\",\n \"2B shows an annular illumination mode in which the intensity distribution of the source is confined to an annulus to limit the range of angles of incidence of the off-axis illumination, considering that the spatial intensity distribution at the pupil plane is related to the angular distribution at the mask plane, which is a Fourier transform plane to the pupil plane.\",\n \"The annulus may be characterized by the values σi and σo, which are the ratios of its inner and outer radii to the radius of the pupil.\",\n \"FIG.\",\n \"2C illustrates the intensity distribution of the quadrupole illumination mode, the use of which sometimes gives improved imaging results to the use of annular or coherent modes.\",\n \"Conventionally, in using such a quadrupole configuration, it is assumed that the patterned structure of the mask to be projected includes sub-patterns of orthogonal lines along x and y axes and the illumination is oriented such that each of the four poles is situated in a respective one of the four quadrants defined by these x and y axes and at their point of intersection.\",\n \"In specific applications it has been found that superior performance can be obtained using dipolar illumination modes.\",\n \"FIG.\",\n \"2D shows an example of the dipolar illumination intensity distribution for a dipole mode.\",\n \"The two poles POLE1, POLE2 of this mode are located off the optical axis OA of the imaging system.\",\n \"For illustrative purposes, the two poles illustrated in FIG.\",\n \"2D are said to lie along the x axis (second direction) and may be optimal for imaging lines extending parallel to the y axis (first direction), i.e.\",\n \"perpendicular to the pole orientation axis POA joining the two poles.\",\n \"Sometimes the x and y axis are referred to as horizontal and vertical, respectively, but these terms typically do not bear any relation to the orientation of the machine.\",\n \"As illustrated in FIG.\",\n \"2D the pole shape of the poles POLE1, POLE2 in conventional systems may correspond to an azimuthal section of an annulus.\",\n \"Due to the desire that the first diffraction order should pass completely through the aperture of the projection objective to obtain maximum contrast, limitations result for the radial width Δσ=σo−σi of the poles and for the azimuthal width (width in circumferential direction) of the poles defined by the pole angle Θ.\",\n \"With dipole illumination, the effective light source is confined to two poles, in order to create the conditions for two-beam imaging with theoretical ideal contrast.\",\n \"FIG.\",\n \"3 illustrates schematically a projection exposure system configured for dipole illumination mode.\",\n \"Primary radiation provided by a primary light source LS is transformed by an illumination system ILL to provide illumination radiation incident on a mask M bearing a pattern PAT.\",\n \"The radiation is diffracted by pattern PAT and forms projection radiation propagating through the projection objective PO, which images the pattern of the mask onto the substrate, which is a wafer W coated with a resist layer RES in the exemplary embodiment.\",\n \"The illumination system ILL includes a pupil shaping unit PSU to create an effective source ES formed by a predefined intensity distribution at a pupil plane PILL of the illumination system, where the predefined intensity distribution is a dipole illumination characterized by two lenticular poles POLE1 and POLE2.The pupil plane PILL, where the effective source ES is formed, is a Fourier transform surface with respect to the object surface of the projection objective PO, where the mask M is situated.\",\n \"Therefore, the spatial distribution of light intensity of the effective source ES determines an angular distribution of illumination radiation incident on the mask M. A condenser system CS is provided to perform the Fourier transformation.\",\n \"The pupil surface PPO of the projection objective is optically conjugated to the pupil surface PILL of the illumination system.\",\n \"Therefore, in the absence of a mask, a spatial intensity distribution equivalent to the intensity distribution at the effective source ES may be formed in the pupil surface PPO of the projection objective.\",\n \"Where a mask bearing a pattern is inserted between the illumination system and the projection objective, the intensity distribution in the pupil plane PPO of the projection objective also contains diffraction information corresponding to the properties of the mask pattern PAT.\",\n \"FIG.\",\n \"4 illustrates schematically a circular pupil PPO of a projection objective having unit radius (length=1) corresponding to the utilized image-side numerical aperture NA at imaging conditions beyond the coherent resolution limit of a periodic pattern of mutually parallel lines running in a first direction (y direction) having periodicity length (pitch) P in a second direction (x direction).\",\n \"A symmetric two-beam interference imaging condition is assumed, where a first diffraction order (+1 or −1) coincides with the zeroth order (0).\",\n \"In this representation, all illumination directions which contribute constructively to two-beam interference correspond to pupil positions lying within the lenticular (lens-shaped) regions LR at opposite edges of the pupil in the x direction.\",\n \"Those lenticular regions (also denoted as “planar circular two-angles” result from a partial overlap of circles of equal size corresponding to neighbouring diffraction orders.\",\n \"A distance d between the centers of the lenticular regions is determined by d=λ/(P*NA).\",\n \"The angular width of the lenticular area (width in circumferential direction) may be defined by a pole angle θ between the opposing corners of the area in the y direction, where pole angle θ is twice the pole half angle α (i.e.\",\n \"θ=2*α).\",\n \"The size of the lenticular area, i.e.\",\n \"the area AOPT of the hatched lenticular region LR in FIG.\",\n \"4, may be calculated as AOPT=θ−sin(θ) with cos(α)=d/2=λ/(2*P*NA).\",\n \"It is contemplated that a maximum contrast is possible if all illumination directions corresponding to pupil positions within the lenticular regions LR are used.\",\n \"The size AOPT of the lenticular regions may be calculated based on the following considerations explained now in connection with FIG.\",\n \"4.The area AOPT is four times the difference between the area AS of the circular sector with sector angle α, and the area AABC of triangle ABC indicated in FIG.\",\n \"4.The difference area AS-AABC is hatched darkly in FIG.\",\n \"4.Calculating the angles in radians, the sector area AS is calculated as follows: AS=(α/2π)·π·r2, where r=1 is the unit radius of the pupil.\",\n \"Therefore, AS=(α/2π)·π=α/2.With distance A−C=cos (α) and distance B−C=sin (α) the area AABC of the triangle calculate as: AABC=(sin (α)·cos (α))/2.Further considering that 2·sin (α)·cos (α)=sin (2·α), the area AOPT of the lenticular region LR calculates as follows: A OPT = 4 · ( A S - A ABC ) = 4 · ( α / 2 - ( sin ( α ) · cos ( α ) ) / 2 ) = 2 · α - sin ( 2 · α ) = θ - sin ( θ ) An illumination pole having the size and shape of a desirable (e.g., optimum) lenticular region LR may be characterized by a pole width PW measured between an inner and an outer pole edge in a direction parallel to the pole orientation axis POA, and a pole height PH measured between pole edges in a direction perpendicular to the pole orientation axis, i.e.\",\n \"in y direction (see FIG.\",\n \"5A).\",\n \"Defining a pole dimension ratio PDR as the aspect ratio between pole PH height and pole width PW according to PDR=PH/PW, for the lenticular regions PDROPT=sin(α)/(1−cos(α)).\",\n \"In conventional systems, only a fraction of those illumination directions is normally used.\",\n \"For illustration purposes, FIG.\",\n \"4 shows conventional poles CP having a shape corresponding to an azimuthal section of an annulus within the lenticular regions LR.\",\n \"Limitations regarding radial width Δσ and pole angle result from the desire that the first diffraction order should fall completely within the aperture of the objective to obtain maximum contrast.\",\n \"As evident from FIG.\",\n \"4, the area of the conventional poles CP is significantly smaller than the area AOPT of the lenticular zones which could be used for the imaging process at good (e.g., optimum) contrast.\",\n \"For example, the size of the conventional poles may be 50% or less of the area AOPT.\",\n \"The pole dimension ratio PDR of a conventional pole usually differs significantly from the pole dimension ratio PDROPT defined above.\",\n \"For example, a circular pole would correspond to PDR=1.The annular segment shaped conventional poles CP depicted schematically in FIG.\",\n \"4 may have varying pole dimension ratio depending on the selected values for Δσ and pole angle.\",\n \"Generally, as the pole height increases, the pole width will decrease, and vice versa.\",\n \"Now consider a lens or another optical element having an optical surface at or close to the pupil surface of the projection objective, where light intensity is concentrated at the edge of the lens surface in regions corresponding to the poles of the dipole illumination.\",\n \"Studies have shown that effects of lens heating may cause characteristic deformations of wavefronts passing the projection objective due to local deformation of the lenses and/or due to localized radiation-induced changes of refractive index.\",\n \"For example, where a dipolar intensity distribution is used, the local deformation of lenses or other optical elements and associated wavefront deformations may be dominated by astigmatic contributions.\",\n \"In the following a number of embodiments are described where a multipolar illumination mode includes at least one substantially dipolar intensity distribution having two illumination poles, where the pole area APOLE of poles is selected to be very close to or equal to the pole area AOPT defined above.\",\n \"Negative effects caused by localized lens heating may be reduced significantly when compared to using conventional poles.\",\n \"FIGS.\",\n \"5A-5C illustrate where the poles POLE 1 and POLE 2 of the dipolar intensity distribution each have a lenticular pole shape defined by two convexly curved edges having opposite sense of curvature and centers of curvature essentially on a line parallel to the pole orientation axis POA.\",\n \"In FIG.\",\n \"5A the size and shape of the poles is adjusted such that the poles exactly fit the lenticular region LR corresponding to the given pitch P of the sub-pattern to be printed.\",\n \"The conditions APOLE=AOPT and PDRPOLE=PDROPT hold for the pole area and pole dimension ratio, respectively.\",\n \"FIG.\",\n \"5B shows an example where all light intensity is concentrated in poles POLE1, POLE2 slightly smaller than the lenticular area by about 10%.\",\n \"Although not all illumination directions theoretically contributing to constructive interference are used in this setting, the intensity of the poles is still distributed over a relatively large area on optical surfaces near pupil surfaces to eliminate or alleviate lens heating problems.\",\n \"In FIG.\",\n \"5C the size of the poles POLE1, POLE2 is slightly larger than the pole area AOPT of poles such that a small fraction of illumination directions falls outside the pupil, thereby not contributing to imaging, and some illumination angles smaller than the lowest limit of the optimum angular distribution according to FIG.\",\n \"4 are also present.\",\n \"As light energy is distributed over relatively large areas around the poles, lens heating problems may be smallest in FIG.\",\n \"5C with potential trade-offs in attainable contrast.\",\n \"Optimum compromise settings may be evaluated by simulation or test exposures.\",\n \"FIGS.\",\n \"6A-6B illustrate schematically one option to generate biconvex, lenticular (lens-shaped shaped) illumination poles as described above in a modified conventional illumination system configured to generate illumination poles having

complete illuminated surface of the raster element RE1.Such arrangement allows to generate the dipolar intensity distribution essentially without blocking any parts of the beam so that there is no intensity loss involved in the generation of the dipolar intensity distribution.\",\n \"The raster element RE1 can be formed by an array of refractive lens segments.\",\n \"Each raster segment RS may be formed by a segment of a lens or a prism where an entry-side surface and an exit-side surface of the raster segment are oriented such that a desired redirection of radiation is caused by refraction at the segment surfaces as the radiation passes through the raster segment.\",\n \"The rhombohedral shape of the raster segments RS determines the shape of the poles in the pupil surface PILL.\",\n \"In FIG.\",\n \"9A the raster segments are numbered “1” and “2” to illustrate which raster segments contribute to the illumination intensity in the two poles POLE1 and POLE2 shown in FIG.\",\n \"9B.\",\n \"The structure of the raster segments is adjusted to redirect at least a major portion of impinging radiation to the two poles.\",\n \"As illustrated by dashed lines in some raster segments of FIG.\",\n \"9A, the raster elements may also be segmented into other shapes, such as triangular raster segments, where the size and shape of the triangles are adapted to define, in combination, a rhombohedral area corresponding to the desired pole shape.\",\n \"In some embodiments, the raster element RE1 may be designed as a diffractive computer generated hologram (CGH) assigning to each of the raster segments RS a diffractive structure effective to redirect light intensity present in a partial beam impinging on the raster segment into the associated pole.\",\n \"The raster segments may have a shape differing from the shape of the desired poles, e.g.\",\n \"a rectangular shape.\",\n \"The diffractive structure may be formed on the surface of a transparent substrate, such as a plane plate made of fused silica or calcium fluoride.\",\n \"The raster segments may also be formed of grooves etched into the surface to provide segments of a Fresnel lenses.\",\n \"The depth and width of the grooves may be in the order of micrometers, for example.\",\n \"Each raster segment may be in the order of millimeters in size and the entire array forming the raster element may have typical dimensions of one or a few centimeters.\",\n \"The basic distribution of angles introduced by the raster element RE1 may be modified within the pupil shaping unit by setting the elements of the variable zoom lens group Z and/or the variable axicon group AX accordingly.\",\n \"In one configuration, the separation between the axicon elements AX1 and AX2 is set to zero (contact between axicon surfaces) such that no radial redirection of light intensity is effected by the axicon group AX.\",\n \"In other configurations, a defined separation may be set, which generally causes a central symmetric dilatation of the radiation intensity distribution, which may be useful in some cases.\",\n \"Adjusting the magnification of the zoom lens group Z allows to adapt the illumination intensity distribution in the pupil surface PILL of the illumination system to different NA values in a homomorphous imaging step.\",\n \"It is to be noted that the conditions for the pole area APOLE, pole height PH and pole width PW as defined above remain unchanged as long as P*NA=2 k1*λ=const.\",\n \"Therefore, the area of the poles as well as the pole height and pole width may be considered as a function of parameter k1 alone, where k1<1 is a process dependent parameter that incorporates everything in a lithography process that is not wavelength or numerical aperture.\",\n \"Generally, any process or system modification that allows improvements in resolution effectively reduces the k1 factor.\",\n \"Diffraction-limited values are 0.25 for incoherent and 0.5 for coherent illumination, for example.\",\n \"Where k1 stays essentially constant, sub-patterns with different predominant periodicity values P (pitches) may be illuminated using one and the same raster element RE1 by simply adjusting the appropriate NA value using the zoom lens group Z.\",\n \"With other words: one type of raster element with fixed configuration, such as a diffractive optical element, may be sufficient for different processes defined by one particular k1 value (or a small variation of k1).\",\n \"Different values for APOLE, PW and/or PH and different pole patterns may also be obtained by providing several different, interchangeable first raster elements.\",\n \"An automatic changer may be used to exchange raster elements of different configuration in the illumination system.\",\n \"In general, the pupil-shaping unit may include at least one optical modulation device configured to controllably change an angular distribution of radiation incident on the optical modulation device such that a desired intensity distribution is obtained in the pupil surface of the illumination system.\",\n \"Although the optical modulation device may have a fixed configuration to obtain only one type of intensity distribution (which may be changeable by additional variable optical elements), it is possible that the optical modulation device has an array of individual elements configured to be driven individually to change the angular distribution of radiation incident on the individual elements.\",\n \"The optical modulation device may include a controllable micro-mirror array, for example.\",\n \"Various optical modulation devices which may be used when modified for that purpose are disclosed in applicant's international patent application published as WO 2005/026843 A2.The disclosure of this application is incorporated herein by reference.\",\n \"FIGS.\",\n \"10A-10B show diagrams illustrating, for an exemplary projection exposure systems, improvements that may be obtained if an optimized dipole setting is used instead of a conventional setting.\",\n \"In the diagrams, pupil coordinates in terms of image-side numerical aperture NA are drawn in the abscissa.\",\n \"The ordinates show values for the phase error value of the overall wavefront aberration.\",\n \"The value “0” corresponding to the optical axis.\",\n \"Each diagram shows an “x-cut” parallel to the x-axis (second direction) and an “y-cut” perpendicular thereto in the first direction.\",\n \"An x-dipole (orientation of pole orientation axis along x-direction) is used for all

CONV shown in FIG.\",\n \"10A.\",\n \"An x-dipole setting with lenticular poles with APOLE=AOPT was used for the experiment illustrated in FIG.\",\n \"10B.\",\n \"The x-cut in both experiments illustrates that the localized heating in the region of the poles generally aligned along the x-direction leads to relatively strong wavefront aberrations close to the outer edge of the pupil where the energetic centriods of the poles are positioned.\",\n \"In contrast, essentially no wavefront aberration is caused on and close to the optical axis in the center of the pupil.\",\n \"In the y-direction a relatively large variation of wavefront aberrations occurs superimposed onto a slight gradient from the upper edge to the lower edge of the pupil in this specific type of projection objective used for the experiment.\",\n \"The general characteristics of the local distribution of wavefront aberrations caused by lens heating are quite similar in the experiment according to FIG.\",\n \"10B.\",\n \"Note, however, that the absolute amount of wavefront aberration caused by lens heating is reduced by about a factor two, i.e.\",\n \"reduced to about 50% of the value for the conventional setting in the x-direction (different scales in the ordinates in FIG.\",\n \"10A, in FIG.\",\n \"10B).\",\n \"This significant improvement is attributed to the fact that radiant energy present within the projection beam is distributed over larger areas at the position of the poles, whereby the energy distribution in smeared out over a larger area, thereby reducing associated lens heating effects on wavefront aberrations.\",\n \"The effect is less pronounced in the y-direction.\",\n \"In some embodiments, the multipolar illumination is a pure dipole illumination, where the intensity distribution in the pupil surface of the illumination system is formed by one substantially dipolar intensity distribution having exactly two illumination poles.\",\n \"Such dipole illumination may be used, for example, to print periodic patterns with features essentially aligned in one direction only.\",\n \"As a practical example, a layer of a highly integrated flash memory device may be strongly dominated by lines running in direction only.\",\n \"Due to the relatively large pole height PH of the optimized pole areas those dipole illuminations are also useful to improve contrast of sub-patterns not running at the predominant direction, but at an angle thereto since the dipolar intensity distribution includes illumination directions significantly deviating from the direction defined by the pole orientation axis.\",\n \"The multipolar illumination mode may include two substantially dipolar intensity distributions (“dipoles”) superimposed on each other, where the pole orientation axes of the dipoles are rotated relatively to each other, for example by 90°.\",\n \"FIG.\",\n \"11 depicts schematically the intensity distribution in the illumination pupil for a quadrupole illumination having two pairs of lenticular poles relatively rotated by 90° around the optical axis to form four lenticular poles, POLE1, POLE2, POLE3, POLE 4, where the pole orientation axis POAx of the first dipolar intensity distribution (forming poles POLE1 and POLE2) is oriented along the x-direction, whereas the pole orientation axis POAy of the second dipolar intensity distribution (forming poles POLE3 and POLE4) is oriented perpendicular thereto in the y-direction.\",\n \"A bi-directional pattern having periodic features in x- and y-direction may be printed with high contrast for both directions.\",\n \"The area of each of the poles corresponds approximately to the optimum area AOPT in this example.\",\n \"As illustrated schematically in FIG.\",\n \"12, the method and apparatus may also be used in exposure processes which do not exploit the full resolution potential of the projection exposure apparatus.\",\n \"For example, a multi-polar illumination mode may be set for a pattern or sub-pattern having features spaced apart periodically at a predominant periodicity length P where the condition 0.7*λ/NA BACKGROUND This section provides background information related to the present disclosure and is not necessarily prior art.","An application (referred to interchangeably in this disclosure as an “app”), such as a mobile app, may contain multiple deep states.","For example, in an app that rates the quality of restaurants based on social media opinion data, the detail page for each restaurant would be considered a deep state.","Deep states are reachable from within the app through a sequence of user actions that can involve navigating through multiple menu screens (or, views) as well as interactions with user interface elements.","Each of these menu screens and user interface elements can be mediated by a unique view controller associated with that displayed screen.","Usually, these deep states are accessible only from within the app itself web search engines operating outside the app, for example, cannot reach the deep states within the app.","This means that when a user conducts a conventional web search for restaurants and wants to explore one of the returned choices in a specialized restaurant rating app, the user would have to manually copy and paste the name of the selected search result into the search field of the restaurant rating app and command the restaurant ranking app to access its internal deep state corresponding to the selected restaurant.","This represents undesirable additional interaction required of the user.","If deep states of apps could be exposed to external apps and computer processes, the user could enjoy additional functionality and convenience.","For example, the user could begin a search for a suitable restaurant using an Internet-based search server and then, by selecting one of the results of that search, be automatically led to the appropriate deep linked page of a specialized restaurant ranking app.","However, implementing such functionality requires developer effort and requires deep linking expertise that the developer may not possess.","When app development is limited by time, budget, or expertise, deep link functionality for some or even all of the states of an app may not be a high enough priority to get implemented.","Mobile operating systems, such as the iOS operating system from Apple Inc. and the Android operating system from Google Inc., may allow a developer to provide data to the operating system for indexing.","In the iOS operating system, this may take the form of a CSSearchableItem (where the CS stands for Core Spotlight) object.","The developer may implement code that bookmarks certain states of an app by providing information about those states to the operating system.","In the iOS operating system, this may take the form of an NSUserActivity object (where NS stands for NeXTSTEP).","Then, users can perform a search through the operating system, where relevant data or states from the developer's app are identified.","If a user selects one of those activities from an operating system interface, such as a search dialogue or a recent tasks menu, the developer's code can restore the app to the state corresponding to the bookmarked activity.","A bookmarked activity on a first device may even be continued on a different device (assuming the app is also installed on the other device).","Via inter-device communication, the operating system of the first device notifies the operating system of the other device what state the user was most recently interacting with.","In addition, the developer may specify that certain types of data, such as telephone numbers and names from a contact database maintained by the app, be indexed by the operating system.","When a user indicates to the operating system that one of those data objects (for example, a certain contact) is of interest, the developer's code can transition to a state of the app that presents that data object for viewing or editing.","In order to take advantage of these operating system capabilities, the developer may implement code that can restore the app to a state based on indicated activity or data object.","However, these activities and data objects may be known only to the operating system or to search systems maintained by a developer of the operating system.","In other words, third party apps and search services may be unable to access this data and navigate directly to the states or data objects within the app.","Further, developing code to display data objects, index data objects, bookmark activities, and continue activities requires developer effort and may not be accomplished for any of an app's states much less for all of the app's states.","As a result, these enhanced operating system capabilities may not be available for a variety of states of an app and may also not be accessible to third party apps and search systems.","In FIG.","1 , the enhanced operating system functionality is graphically depicted.","On a user device, an operating system 100 executes a first app (referred to as “App A”) 104 .","App A 104 includes a representative set of views, View A 108 - 1 , View B 108 - 2 , View C 108 - 3 , View D 108 - 4 , and View E 108 - 5 (collectively, views 108 ).","The views 108 may be managed by one or more view controllers, which may be developed according to the model-view-controller (MVC) software architecture pattern.","As an example only, App A 104 is a restaurant information app, View A 108 - 1 is a home (or, default) state of App A 104 from which restaurant searches by cuisine, geography, etc.","can be performed.","Continuing the example, View B 108 - 2 is a two-dimensional app interface showing restaurant locations, View C 108 - 3 is a restaurant detail view, View D 108 - 4 is a list of restaurants by cuisine, and View E 108 - 5 is a list of recently-reviewed restaurants.","In various implementations, including this example, a single view may be a template populated with entity-specific data.","For example, View C 108 - 3 may have a visual layout for a restaurant specifying where a photo of the restaurant will be located, the location, size, and font face of the restaurant's name, how reviews will be summarized, etc.","The visual layout view will be instantiated with data corresponding to a specific restaurant from a data store.","App A 104 selects and provides data objects to the operating system 100 for indexing.","For example, App A 104 may provide the names of each of the specific cuisines encompassed by App A 104 .","The operating system 100 can then provide results to users who are searching by that cuisine name.","App A 104 includes an activity handler 112 that receives a continue user activity signal from the operating system 100 .","For example, the continue user activity signal may specify that a certain cuisine type was of interest to a user.","The activity handler 112 then invokes View D 108 - 4 and populates View D 108 - 4 with results corresponding to the specified cuisine.","App A 104 may be selective regarding which cuisines to provide to the operating system 100 for indexing because providing too many data objects may lead to a decrease in their average relevance.","This may cause the operating system 100 to down-rank or even remove indexed objects from search results that do not appear to have high relevance.","App A 104 may, therefore, include programming that indexes a list of the most popular cuisines or cuisines whose names are more likely to be unique to cuisines.","For example, while “American” may be a cuisine name, there is a high false positive rate because this term applies to many other searches than simply cuisine.","However, if a user indicates interest in a cuisine, such as by reviewing the restaurant listings for a certain cuisine one or more times, App A 104 may add that cuisine name to the list of objects to index by the operating system 100 .","In addition, App A 104 may indicate to the operating system 100 , using an activity object, that a user is currently viewing restaurant results for a particular cuisine.","This allows the operating system 100 to maintain essentially a history of activities performed by the user within App A 104 .","In addition, the most recent activity engaged in by the user can be shared with another device, allowing a hand-off of user interaction with that activity from one device to another.","Submitting an activity object to the operating system, allowing later resumption of the activity on the same or another device, is referred to in this disclosure as bookmarking the activity.","Activity objects may be sent to the operating system 100 when the user enters View B 108 - 2 to view restaurant results in a map display.","For example, the activity object sent to the operating system 100 may include a latitude and longitude at a center of the map.","If the user adjusts the center of the map, App A 104 may provide an updated activity object to the operating system 100 indicating the new center point.","App A 104 may further include in the activity object additional data such as filters.","For example, the user may have restricted the displayed results to only those restaurants that are currently open.","This filter may be identified in the activity object provided to the operating system 100 .","The activity handler 112 may receive a continue user activity signal from the operating system 100 indicating that the user is interested in continuing a map view of restaurants at a certain center point with a certain set of filters.","For example only, in the iOS operating system, this may take the form of a continueUserActivity call to the app delegate of the app.","The activity handler 112 then invokes View B 108 - 2 with the provided parameters and presents the user with the desired map view.","The continue user activity signal may have been received from another device on which the user was previously viewing that map display.","As shown in FIG.","1 , the activity handler 112 is programmed to invoke View B 108 - 2 , View D 108 - 4 , and View E 108 - 5 , but not View A 108 - 1 or View C 108 - 3 .","In the operating system 100 , a search index 120 receives data objects from App A 104 .","The search index 120 also receives data objects from other apps and, in some implementations, from the operating system 100 itself, such as the names of frequently-accessed device settings.","For example only, in the iOS operating system, the search index 120 may be referred to as Spotlight and the data objects provided to the search index 120 may take the form of CSSearchableItem objects.","The search index 120 may also receive activity metadata from an activity tracker 124 .","The activity tracker 124 receives activity objects, including from App A 104 .","An activity object may take the form of an NSUserActivity object.","An activity object received by the activity tracker 124 may include metadata similar to that of a data object.","The metadata can be indexed by the search index 120 .","The metadata may take the form of a CSSearchableItemAttributeSet object, which may be the same form used in CSSearchableItem objects.","Activities indicated as public may be shared with a cloud index maintained by the developer of the operating system 100 .","A cloud index interface 128 provides the public activities to the cloud index.","These public activities are selectively indexed by the cloud index, allowing other users to search for and find activities generated by App A 104 even when App A 104 is not installed on their devices.","A handoff controller 132 shares the latest activity with other devices.","In various implementations, the other devices have been authenticated to the handoff controller 132 to indicate that they have permission to receive the latest activities from the present device.","These other devices can, therefore, allow a user to begin an activity on the device where the operating system 100 is executed and resume the activity on another device.","A search interface 136 allows a user to perform a search, such as by entering a text query.","The search index 120 provides relevant search results to the search interface 136 and, upon a user selection, the user-selected result is provided to the activity tracker 124 .","The activity tracker 124 identifies which app corresponds to the user-selected result and sends a continue user activity signal to the relevant app.","The continue user activity signal may include an indicator whether the continue user activity signal pertains to a data object

Application No.","62/252,357, filed Nov. 6, 2015, and U.S.","Provisional Application No.","62/204,960, filed Aug. 13, 2015.The entire disclosures of the applications referenced above are incorporated by reference.","FIELD The present disclosure relates generally to mobile application development and more specifically to deep linking to specific states of mobile applications.","BACKGROUND This section provides background information related to the present disclosure and is not necessarily prior art.","An application (referred to interchangeably in this disclosure as an “app”), such as a mobile app, may contain multiple deep states.","For example, in an app that rates the quality of restaurants based on social media opinion data, the detail page for each restaurant would be considered a deep state.","Deep states are reachable from within the app through a sequence of user actions that can involve navigating through multiple menu screens (or, views) as well as interactions with user interface elements.","Each of these menu screens and user interface elements can be mediated by a unique view controller associated with that displayed screen.","Usually, these deep states are accessible only from within the app itself web search engines operating outside the app, for example, cannot reach the deep states within the app.","This means that when a user conducts a conventional web search for restaurants and wants to explore one of the returned choices in a specialized restaurant rating app, the user would have to manually copy and paste the name of the selected search result into the search field of the restaurant rating app and command the restaurant ranking app to access its internal deep state corresponding to the selected restaurant.","This represents undesirable additional interaction required of the user.","If deep states of apps could be exposed to external apps and computer processes, the user could enjoy additional functionality and convenience.","For example, the user could begin a search for a suitable restaurant using an Internet-based search server and then, by selecting one of the results of that search, be automatically led to the appropriate deep linked page of a specialized restaurant ranking app.","However, implementing such functionality requires developer effort and requires deep linking expertise that the developer may not possess.","When app development is limited by time, budget, or expertise, deep link functionality for some or even all of the states of an app may not be a high enough priority to get implemented.","Mobile operating systems, such as the iOS operating system from Apple Inc. and the Android operating system from Google Inc., may allow a developer to provide data to the operating system for indexing.","In the iOS operating system, this may take the form of a CSSearchableItem (where the CS stands for Core Spotlight) object.","The developer may implement code that bookmarks certain states of an app by providing information about those states to the operating system.","In the iOS operating system, this may take the form of an NSUserActivity object (where NS stands for NeXTSTEP).","Then, users can perform a search through the operating system, where relevant data or states from the developer's app are identified.","If a user selects one of those activities from an operating system interface, such as a search dialogue or a recent tasks menu, the developer's code can restore the app to the state corresponding to the bookmarked activity.","A bookmarked activity on a first device may even be continued on a different device (assuming the app is also installed on the other device).","Via inter-device communication, the operating system of the first device notifies the operating system of the other device what state the user was most recently interacting with.","In addition, the developer may specify that certain types of data, such as telephone numbers and names from a contact database maintained by the app, be indexed by the operating system.","When a user indicates to the operating system that one of those data objects (for example, a certain contact) is of interest, the developer's code can transition to a state of the app that presents that data object for viewing or editing.","In order to take advantage of these operating system capabilities, the developer may implement code that can restore the app to a state based on indicated activity or data object.","However, these activities and data objects may be known only to the operating system or to search systems maintained by a developer of the operating system.","In other words, third party apps and search services may be unable to access this data and navigate directly to the states or data objects within the app.","Further, developing code to display data objects, index data objects, bookmark activities, and continue activities requires developer effort and may not be accomplished for any of an app's states much less for all of the app's states.","As a result, these enhanced operating system capabilities may not be available for a variety of states of an app and may also not be accessible to third party apps and search systems.","In FIG.","1, the enhanced operating system functionality is graphically depicted.","On a user device, an operating system 100 executes a first app (referred to as “App A”) 104.App A 104 includes a representative set of views, View A 108-1, View B 108-2, View C 108-3, View D 108-4, and View E 108-5 (collectively, views 108).","The views 108 may be managed by one or more view controllers, which may be developed according to the model-view-controller (MVC) software architecture pattern.","As an example only, App A 104 is a restaurant information app, View A 108-1 is a home (or, default) state of App A 104 from which restaurant searches by cuisine, geography, etc.","can be performed.","Continuing the example, View B 108-2 is a two-dimensional app interface showing restaurant locations, View C 108-3 is a restaurant detail view, View D 108-4 is a list of restaurants by cuisine, and View E 108-5 is a list of recently-reviewed restaurants.","In various implementations, including this example, a single view may be a template populated with entity-specific data.","For example, View C 108-3 may have a visual layout for a restaurant specifying where a photo of the restaurant will be located, the location, size, and font face of the restaurant's name, how reviews will be summarized, etc.","The visual layout view will be instantiated with data corresponding to a specific restaurant from a data store.","App A 104 selects and provides data objects to the operating system 100 for indexing.","For example, App A 104 may provide the names of each of the specific cuisines encompassed by App A 104.The operating system 100 can then provide results to users who are searching by that cuisine name.","App A 104 includes an activity handler 112 that receives a continue user activity signal from the operating system 100.For example, the continue user activity signal may specify that a certain cuisine type was of interest to a user.","The activity handler 112 then invokes View D 108-4 and populates View D 108-4 with results corresponding to the specified cuisine.","App A 104 may be selective regarding which cuisines to provide to the operating system 100 for indexing because providing too many data objects may lead to a decrease in their average relevance.","This may cause the operating system 100 to down-rank or even remove indexed objects from search results that do not appear to have high relevance.","App A 104 may, therefore, include programming that indexes a list of the most popular cuisines or cuisines whose names are more likely to be unique to cuisines.","For example, while “American” may be a cuisine name, there is a high false positive rate because this term applies to many other searches than simply cuisine.","However, if a user indicates interest in a cuisine, such as by reviewing the restaurant listings for a certain cuisine one or more times, App A 104 may add that cuisine name to the list of objects to index by the operating system 100.In addition, App A 104 may indicate to the operating system 100, using an activity object, that a user is currently viewing restaurant results for a particular cuisine.","This allows the operating system 100 to maintain essentially a history of activities performed by the user within App A 104.In addition, the most recent activity engaged in by the user can be shared with another device, allowing a hand-off of user interaction with that activity from one device to another.","Submitting an activity object to the operating system, allowing later resumption of the activity on the same or another device, is referred to in this disclosure as bookmarking the activity.","Activity objects may be sent to the operating system 100 when the user enters View B 108-2 to view restaurant results in a map display.","For example, the activity object sent to the operating system 100 may include a latitude and longitude at a center of the map.","If the user adjusts the center of the map, App A 104 may provide an updated activity object to the operating system 100 indicating the new center point.","App A 104 may further include in the activity object additional data such as filters.","For example, the user may have restricted the displayed results to only those restaurants that are currently open.","This filter may be identified in the activity object provided to the operating system 100.The activity handler 112 may receive a continue user activity signal from the operating system 100 indicating that the user is interested in continuing a map view of restaurants at a certain center point with a certain set of filters.","For example only, in the iOS operating system, this may take the form of a continueUserActivity call to the app delegate of the app.","The activity handler 112 then invokes View B 108-2 with the provided parameters and presents the user with the desired map view.","The continue user activity signal may have been received from another device on which the user was previously viewing that map display.","As shown in FIG.","1, the activity handler 112 is programmed to invoke View B 108-2, View D 108-4, and View E 108-5, but not View A 108-1 or View C 108-3.In the operating system 100, a search index 120 receives data objects from App A 104.The search index 120 also receives data objects from other apps and, in some implementations, from the operating system 100 itself, such as the names of frequently-accessed device settings.","For example only, in the iOS operating system, the search index 120 may be referred to as Spotlight and the data objects provided to the search index 120 may take the form of CSSearchableItem objects.","The search index 120 may also receive activity metadata from an activity tracker 124.The activity tracker 124 receives activity objects, including from App A 104.An activity object may take the form of an NSUserActivity object.","An activity object received by the activity tracker 124 may include metadata similar to that of a data object.","The metadata can be indexed by the search index 120.The metadata may take the form of a CSSearchableItemAttributeSet object, which may be the same form used in CSSearchableItem objects.","Activities indicated as public may be shared with a cloud index maintained by the developer of the operating system 100.A cloud index interface 128 provides the public activities to the cloud index.","These public activities are selectively indexed by the cloud index, allowing other users to search for and find activities generated by App A 104 even when App A 104 is not installed on their devices.","A handoff controller 132 shares the latest activity with other devices.","In various implementations, the other devices have been authenticated to the handoff controller 132 to indicate that they have permission to receive the latest activities from the present device.","These other devices can, therefore, allow a user to begin an activity on the device where the operating system 100 is executed and resume the activity on another device.","A search interface 136 allows a user to perform a search, such as by entering a text query.","The search index 120 provides relevant search results to the search interface 136 and, upon a user selection, the user-selected result is provided to the activity tracker 124.The activity tracker 124 identifies which app corresponds to the user-selected result and sends a continue user activity signal to the relevant app.","The continue user activity signal may include an indicator whether the continue user activity signal pertains to a data object or an activity object.","SUMMARY A mobile application development system includes a developer portal and an offline analysis system.","The developer portal is configured to receive a copy of a first application from a first developer and provide a routing library to the first developer for incorporation into the first application prior to the first developer distributing an augmented application via a digital distribution platform.","The routing library is incorporated into the first application to form the

be bookmarked for the user to return to later or for the activity to be resumed on another of the user's devices.","The developer may also write code that submits data to the OS for indexing so that the OS can surface the data, such as in response to an OS-wide search.","In order to implement this functionality, the developer writes code that allows the app to resume to an activity indicated by the OS or to a state that interacts with a data object specified by the OS.","In some implementations, the activity object received from the OS fully specifies the activity for the app to resume, even if this particular copy of the app has not performed that activity previously.","Meanwhile, for data objects, some apps may be able to show a state of the app corresponding to a certain data object only if that data object has been stored by the present copy of the app.","In other implementations, or for certain apps, certain data objects may fully specify the state to which the app should return to view that data object.","This generally means that the data for the data object is either known by the app, accessible to the app, or provided to the app from the OS within the continue user activity request.","For data objects that do not fully specify the state of an app, these data objects may be specific to the app where they were created, and cannot be accessed by other copies of the app.","Even though the developer may have implemented, for some or all states and for some or all data objects, the ability to resume that activity or navigate to that data object, there may be no provision for third parties, such as search services or other apps, to directly link to those activities or data objects within the app.","The present disclosure identifies activities implemented by the developer and provides a library that, when presented with an appropriate deep link, can invoke the internal activity handling of the app.","This allows the developer's efforts in interacting with the OS to be leveraged to provide deep link access to third parties.","For some apps, the developer may not have implemented OS search functionality for some states and for some data.","For some apps, the developer may not have implemented that functionality for any states or any data.","The present disclosure, therefore, describes how the developer can specify which states of an app should have this functionality enabled.","The present disclosure describes how the application can be supplemented to enable this functionality for the app, such as by recording sequences of user interface events that can be replayed to reach deep states of the app.","When a routing library according to the principles of the present disclosure is used to enable activity bookmarking and data indexing, the configuration of the routing library may be specified by the developer.","In various implementations, an agent of the developer may be able to make configuration decisions, such as which states to bookmark and which data to index, and those configuration decisions are relayed to the routing library.","In various implementations, the routing library may periodically update this configuration so that the developer can change the configuration even for apps already installed on devices.","A developer portal may allow even non-programmers working with the developer to specify business rules.","For example, a marketing or user experience professional at the developer may specify what data to submit to the OS for indexing in order to optimize the search relevancy of the app for a given OS.","A developer portal according to the present disclosure provides a routing library to the developer for integration into an app, and that routing library implements the above functionality.","For example, based on configuration data, the routing library may bookmark certain activities with the OS and may submit certain data objects for indexing to the OS.","The configuration data may be generated at the time of onboarding the app, and may be generated manually, with artificial intelligence, or with operator-supplemented artificial intelligence.","In addition, the routing library may service continuing activity requests from the OS, such as by executing a series of user interface events to return to the selective activity or to display the selected data.","The routing library may also handle incoming links, such as from other apps or from browser instances.","The routing library may take the form of a dynamic link library (DLL), a dylib, or a software development kit (SDK).","The routing library may be downloaded by the developer and imported into the integrated development environment (IDE) of the developer, such as the Xcode IDE from Apple Inc.","In some implementations, the routing library is either already compiled or includes make files and other configuration files allowing the routing library to be compiled.","The developer may integrate the routing library simply by instructing the IDE to add the routing library to their app's project, such as by adding the routing library to an import list or to a list of included code modules.","The developer may also need to update a configuration file to indicate that the routing library will handle certain uniform resource identifiers (URIs) or activity types.","The configuration file may take the form of an information property list (Info.plist) file.","In various implementations, a script may be provided along with the routing library that performs the configuration file update as well as the import of the routing library into the current IDE project.","Meanwhile, the developer portal supplies the app to an offline analysis system that determines how to access states of interest.","The states of interest may be specified by the app developer or determined by the developer portal.","In brief, an offline analysis system of the developer portal determines what sequence of user interface (UI) actions a user would take to reach a state of interest.","That UI action sequence can be replayed by the routing library within an app on a user's device to arrive at the state of interest.","In other words, the routing library simulates the UI actions users would themselves perform to reach a deep state.","By simulating the UI actions, the routing library avoids the user having to perform each UI action and will generally be far faster than a user manually performing the sequence of UI actions.","The user may not even see some of the intermediate states when the routing library is navigating to the deep state of interest, or these intermediate states may only be visible briefly.","The UI action sequences for the deep states of an app may be integrated into the app along with the routing library, or may be downloaded by the routing library once the app is installed.","In some implementations, a UI action sequence can be encoded as part of a link designating the app and serviced by the routing library.","Without further effort from the developer, the app now has deep link functionality that can be accessed from external sources.","For example, a search system could provide results that lead directly to deep states of the app.","Or a third party app could easily direct users to deep states of the app.","This may increase the visibility of the app and allow for tighter integration and better overall user experience with the app.","In addition, now that the developer portal is responsible for deep linking, deep links can be added or modified without requiring assistance from the developer's software programmers, who may be working on other projects and have other priorities.","In other words, a business person, such as an advertising or marketing professional working for an app developer, may use the developer portal to identify which states of the app should be deep-linkable.","The business person could even remove states from the list of deep-linked states, all without requiring the assistance of a software programmer.","Block Diagram In FIG.","2, additional details are presented.","As noted above, a developer 204 provides an app (referred to as “App A”) to a developer portal 208.The developer portal 208 provides a copy of a routing library to the developer 204 for incorporation into App A, creating an augmented version of App A.","The developer 204 provides the augmented App A, which is still referred to below as App A for simplicity, to a digital distribution platform 212 for distribution to end users.","The digital distribution platform 212 provides native apps to user devices and may be specific to an OS.","Example digital distribution platforms include the GOOGLE PLAY digital distribution platform by Google, Inc., the APP STORE digital distribution platform by Apple, Inc., and the WINDOWS PHONE digital distribution platform by Microsoft Corp.","If the developer 204 had already provided App A to the digital distribution platform 212 before augmentation with the routing library, the developer 204 can release the augmented App A as a new version of App A.","The user of a user device 220 installs App A (as augmented) from the digital distribution platform 212.In the user device 220, one or more processors (which may encompass general purpose processors as well as additional co-processors, such as physical sensor processors and graphics processors) execute instructions from memory.","Some of these instructions correspond to an operating system 224, a browser 228, an installed copy of App A (referred to as App A 232), and a third party app (App B 236).","The operating system 224 includes an installed app registry 240 and a link router 244.The link router 244 receives links, such as URLs (uniform resource locators) and URIs (uniform resource identifiers), and determines how to handle those links.","Generally, the link router 244 handles a link by forwarding it to a registered receiver.","The link router 244 checks the installed app registry 240 to determine whether an app has claimed a particular scheme, domain, or other filter that matches the link.","If not, the link may be passed to the browser 228, which may have registered a set of schemes for protocols such as HTTP (hypertext transfer protocol), HTTPS (HTTP secure), FTP (file transfer protocol), Telnet, and Gopher.","In some implementations, when the link specifies a web server address, the link router 244 may contact the web server to obtain a list of authorized apps.","In this way, the link router 244 verifies that an app that has registered a certain domain is authorized by that domain to handle links.","This prevents apps from commandeering links to which they're not eligible.","If an app that has registered a domain is authorized by the web server host of that domain, the link router 244 can provide the link to the registered app.","Routing library 260, received from the developer portal 208, causes App A 232 to register a specific scheme or domain with the installed app registry 240.The scheme may be based on an identifier of the developer portal 208 as well as an identifier of App A.","For example, a test string associated with the developer portal 208 (such as “portal”) may be concatenated with a text string corresponding to App A (such as “appa”).","As a specific example, the scheme registered by App A 232 may be “portal-appa://”.","In other implementations, the text string associated with the developer portal 208 may not be human-readable.","When the link router 244 receives a link, such as from the browser 228, where the scheme matches “portal-appa://”, the link router 244 forwards that link to App A 232, where the link is received and handled by the routing library 260.The routing library 260 parses the link and navigates to a deep state indicated by the link.","For illustration only, in FIG.","2, View A 268-1, View B 268-2, and View C 268-3 (collectively, views 268) are shown.","In many apps, more than three views will be present.","In various implementations, multiple or all views may be controlled by a single view controller.","In other implementations, each view may be controlled by a separate view controller.","For illustration only, the routing library 260 is shown simulating events from a predetermined UI event sequence identified by an example link.","The link is received by the routing library 260 and corresponds to a deep state, specifically View C 268-3.The UI event sequence includes a first UI event, causing App A 232 to transition from View A 268-1 to View B 268-2, a second UI event, in which App A remains in View B 268-2, and then a third UI event, causing App A 232 to transition from View B 268-2 to View C 268-3.The routing library 260 would simulate these UI events in series.","A search system 272 of the operating system 224 receives data and activity objects from the routing library 260.The routing library 260 provides the data objects for indexing and the activity objects for bookmarking.","The search system 272 allows a user to search for data and/or activities from App A 232.When the user selects an activity corresponding to App A 232, the search system 272 sends an indication of a selected activity to the routing library 260.The search system 272 is shown in more detail in FIG.","3A and FIG.","3B.","In parallel with providing the routing library from the developer portal 208 to the developer 204, the developer portal 208 provides App A to an offline analysis system 280.The copy of App A provided to the developer portal 208 may be a standard release build, such as an iOS App Store Package (ipa file).","In other implementations, the copy of App A provided to the developer portal 208 may be a special build that allows App A to be run in a simulator, and may include symbols, debugging info, and/or source code that would not ordinarily be present in an app distributed by the digital distribution platform 212.This may allow the offline analysis system 280 to more efficiently or accurately analyze App A.","For example, the copy of App A may be a debug build designed to run in the Simulator application from Apple, Inc. on the OS X operating system.","By contrast, the version of App A distributed by the digital distribution platform 212 is a standard release build.","The offline analysis system 280, as described in more detail below, determines UI event sequences that can be used by the routing library 260 to reach specific views of App A 232.A UI event sequence may be referred to as a breadcrumb trail composed of an ordered sequence of individual breadcrumbs (that is, UI events).","For simplicity, in the remainder of this disclosure, the term breadcrumb will be used to refer to a breadcrumb trail.","The offline analysis system 280 may provide the determined breadcrumbs to a data server 284.The data server 284 includes a data store, such as a relational database, that stores breadcrumbs for each app processed by the offline analysis system 280.Each deep state of an app is associated with a corresponding breadcrumb.","In some implementations, the data server 284 may be implemented as a cloud-based block storage service, such as the S3 (Simple Storage Service) service available from Amazon Web Services.","Access mechanisms define how deep states can be reached for such purposes as display advertisements and deep search results.","For example, a search result may correspond to a specific deep state of an app.","The search result may be a deep view card (DVC, see below) with a link including or indicating a breadcrumb corresponding to that deep state.","Other potential access mechanisms for the search result may include a native deep link prepared by the app developer itself, or a standard URL pointing to a web edition of the app.","One of the available access mechanisms may be selected by a search system and provided along with the search result to a search client.","In other implementations, multiple access mechanisms may be provided within the search result, and the search client determines which access mechanism to use in response to user selection of the search result.","For example, a breadcrumb-based access mechanism may be chosen over a web-based access mechanism when business rules indicate a preference for results to render in native apps instead of in web editions of those apps.","The breadcrumb-based access mechanism, however, may only be available when the app is already installed.","In some implementations, the search client may incorporate, or receive as part of the search result, code that scripts downloading and installing of the app, followed by actuation of a deep link.","The deep link may be actuated by sending a breadcrumb-based URI to the newly-installed app.","The data server 284 may also store configuration settings, such as which deep states to allow links to, which deep states to bookmark as activities, and which data to index.","This configuration may be specified by the developer 204 using the developer portal 208.The data server 284 may also receive index items from the routing library 260.For example, the routing library 260 may report activity objects back to the data server 284.The data server 284 can then analyze user interaction with App A 232 and generate information about how to provide more relevant search results.","In addition, data from the data server 284 may be provided back to the developer 204, essentially providing an easy way to instrument App A 232 to analyze user engagement.","The data server 284 may correlate user activity across multiple apps on the user device 220, thereby further improving search results.","Routing Library Integration with Application In FIG.","3A, an example of App A 232 includes the routing library 260 and also includes an App A handler 300, which was created by the developer of App A 232.As seen in the example of FIG.","3A, the App A handler 300 is able to continue user activities relating to View B 268-2, View D-268-4, and View E-268-5.The App A handler 300 cooperates with an activity creator 304, which updates the search system 272 with activity objects indicating activities the user is performing with App A 232.In various implementations, the search system 272 may include elements similar to those shown in the operating system 100 in FIG.","1.The activity creator 304 may send activity objects to the search system 272 based on user activities associated with View B 268-2, View D 268-4, and View E 268-5.The App A handler 300 also interfaces with a data indexer 308, which may provide data objects to the search system 272 related to View B 268-2, View D 268-4, and View E 268-5.The routing library 260 is able to invoke View A 268-1 and View C 268-3 if the developer of App A 232 has requested that functionality through a developer portal.","The routing library 260 may be able to access View A 268-1 and View C 268-3 by invoking respective view controllers, as described in more detail in U.S. patent application Ser.","No.","15/235,650, filed Aug. 12, 2016, titled “Monitoring and Actuation of View Controller Parameters to Reach Deep States Without Manual Intervention,” with first-named inventor Kalyan Desineni, and having attorney docket no.","17100-000029-US.","The entire disclosure of this application is incorporated by reference.","In other implementations, the routing library 260 may access View A 268-1 and View C 268-3 by replaying sequences of user interface events that are determined in an offline process.","For more information, see U.S. patent application Ser.","No.","15/235,859, filed Aug. 12, 2016, titled “Deep Linking to Mobile Application States Through Programmatic Replay of User Interface Events,” with first-named inventor Kalyan Desineni, and having attorney docket no.","17100-000032-US.","The entire disclosure of this application is incorporated by reference.","While the activity creator 304 developed by the developer of App A 232 provides activity objects for some of the views 268 to the activity tracker 124, the routing library 260 is able to provide activity objects from others of the views 268.For example, the activity creator 304 may create an NSUserActivity object and invoke the becomeCurrent( ) method to provide the activity object to the activity tracker 124.It may be irrelevant to the activity tracker 124 whether the routing library or the App A handler 300 sent the activity object.","When the activity tracker 124 sends a continue user activity signal to App A 232, the routing library 260 traps (such as by overloading, overriding, or swizzling the continue user activity method) the continue user activity signal.","If the continue user activity signal is relevant to the App A handler 300, the continue user activity signal is passed through to the App A handler 300.Otherwise, the routing library 260 handles the continue user activity signal.","Similarly, the routing library 260 and the data indexer 308 developed by the developer of App A 232 may each create CSSearchableItem objects and introduce them to the search index 120, such as by using the indexSearchableItems method.","When the activity tracker 124 provides a continue user activity signal to the routing library 260 related to a data object, the routing library 260 either instantiates a view based on the selected data object or passes the continue user activity signal through to the App A handler 300.The NSUserActivity object may include a unique identifier (such as a title) and an activity type.","In a continue user activity signal, the activity type may differentiate an NSUseractivity object from a CSSearchableItem object.","The NSUserActivity object may also include a list of text keywords to allow the object to be indexed.","The NSUserActivity object may also include a set of metadata, such as a CSSearchableItemAttributeSet, which may include an image and other information.","The set of metadata for an object may be displayed when the object is included in a set of search results and gives the user information about whether the object satisfies their query.","The CSSearchableItem object includes a unique identifier and a set of metadata, which may take the form of a CSSearchableItemAttributeSet.","The CSSearchableItem object may also include an expiration date beyond which the object will be automatically de-indexed by the operating system.","Further, the CSSearchableItem object may include a domain identifier to group related objects.","In various implementations, the routing library 260 and the App A handler 300 may both be able to instantiate one or more of the views 268.For example, the App A handler 300 may be programmed to instruct the activity creator 304 to bookmark activities with respect to View B 268-2.Meanwhile, the routing library 260 may be programmed to submit data for indexing from View B 268-2.When a continue user activity signal is received by the routing library 260, if the continue user activity signal is related to a bookmarked activity, the routing library 260 passes through the continue user activity signal to the App A handler 300.Meanwhile, if the continue user activity signal for View B 268-2 is related to a data object, the routing library 260 itself navigates to View B 268-2 in order to display data related to the data object.","Although not shown in FIG.","3A, App A 232 may include an internal link router that receives deep links and instantiates views based on those deep links.","For links including a scheme registered by the routing library 260, which is different than the scheme registered by the internal link router of App A 232, the routing library 260 receives the deep link and instantiates one of the views 268 based on the link.","For example, the link may specify a breadcrumb to follow in order to arrive at the desired state.","The routing library 260 may override methods invoked by the activity creator 304 and the data indexer 308 to pass activity objects and data objects to the search system 272.In this way, the routing library 260 can first inspect the activity objects and data objects before then passing the activity objects data objects to the search system 272.The routing library 260 will then be aware of which activity objects have been created by the activity creator 304, and can, therefore, service deep links related to those activity objects.","Similarly, the routing library 260 will know which data objects have been indexed by the data indexer 308, and can then service deep links related to those data objects.","In order to allow third party Apps and services to access App A 232 using those deep links, the routing library 260 may upload information from the activity objects and the data objects to a remote server.","In order to service a deep link related to the activity objects from the activity creator 304 and the data objects from the data indexer 308, the routing library 260 can generate a continue user activity signal and send that signal to the App A handler 300.The App A handler 300 may be unaware that the continue user activity signal was received from the routing library 260 instead of from the search system 272.The App A handler 300 can then resume the activity or instantiate a review related to the index data as if the request came directly from the search system 272.In FIG.","3B, another example app, App B 360, is shown.","In App B 360, views 364-1, 364-2, 364-3, 364-4, and 364-5 (collectively, views 364) are shown for illustration.","App B 360 does not include a built-in handler similar to the App A handler 300 of FIG.","3A.","As a result, in order to access any of the views 364, the routing library 260 includes mechanisms (such as breadcrumbs) to access each of the views 364.Further, the routing library 260 is solely responsible for generating activity objects and data objects to send to the search system 272.When a continue user activity signal is received by the routing library 260, the routing library 260 cannot pass the continue user activity signal through and instead is responsible for handling the resumption of an activity or a creation of a view related to a data object.","Routing Library In FIG.","4, an example implementation of the routing library 260 includes registration data 404.The registration data 404 indicates to the operating system that the routing library 260 will handle links having a scheme relating to the routing library 260 and will also handle continue user activity signals relating to the app in which the routing library 260 is incorporated.","In various implementations, the registration data 404 is included in a configuration file of the app into which the routing library 260 is incorporated.","A URI (uniform resource identifier) processor 408 receives a link from the operating system.","For example, the link may have originated from a browser or from a third-party app.","The URI processor 408 extracts a unique ID from the link, which may simply be the text within the URI to the right of the pair of forward slashes following the scheme.","An internal router 412 consults an index data store 416 to determine whether the unique ID from the URI corresponds to a breadcrumb or corresponds to an activity call that will be made to the App A handler 300.In other words, the internal router 412 decides whether a breadcrumb exists to reach the state indicated by the unique ID or whether an activity call should be made to the App A handler 300 to reach the state indicated by the unique ID.","When the internal router 412 determines the unique ID corresponds to a breadcrumb, the internal router 412 sends a breadcrumb ID to a state machine 420.In various implementations, the breadcrumb ID may be the same as the unique ID or may be different as defined by a mapping from the index data store 416.As described in more detail below, the state machine 420 retrieves a breadcrumb from a breadcrumb data store 424 and executes each user interface action within the breadcrumb using a UI replay actuator 428.The state machine 420 may monitor the state of App A 232 to ensure that each user interface event is processed by App A 232 before moving to the next UI event.","If the internal router 412 determines that the unique ID from the URI processor 408 corresponds to an activity or data object handled by the App A handler 300, a signal is sent to an activity call creator 432.The activity call creator 432 creates a continue user activity signal specifying the activity or data object related to the link.","The parameters required for creating the continue user activity signal may be obtained from the index data store 416.The continue user activity signal is passed to the App A handler 300 via a handler interface 436, which may send a continue user activity signal to the App A handler 300 as if the App A handler 300 was receiving that signal directly from the operating system.","As mentioned above, the routing library 260 traps the method called by the operating system to provide a continue user activity signal to the app.","An activity handler 440 of the routing library 260 then receives the continue user activity signal.","The activity handler 440 determines whether the continue user activity signal should be handled by the App A handler 300 already implemented by the developer.","This determination may be based on the index data store 416.In such cases, the activity handler 440 provides the continue user activity as a pass through to the App A handler 300 via the handler interface 436.In apps where the developer has not coded a handler such as the App A handler 300, the activity handler 440 may never transmit pass through activities and the activity call creator 432 and the handler interface 436 may be dormant.","If the activity handler 440 determines that the continue user activity signal, according to the index data store 416, can be resumed using a stored breadcrumb, the breadcrumb ID is provided to the state machine 420 for execution.","So far, the aspects of the routing library 260 related to incoming deep links, whether in the form of a link or a continue user activity signal from the operating system, have been described.","The routing library 260 may also implement functionality that sends activity objects and data objects to the operating system.","This allows the operating system to return search results from the app.","A data indexer 460 determines which data objects of the app to index based on rules from a business rules data store 464.For example only, the data indexer 460 may respond to an app loaded signal to execute upon the app successfully running on the device.","The data indexer 460 may, upon the first execution of the app, send a predetermined set of data objects to the operating system via an operating system interface 468.For example only, with respect to data objects, the operating system interface 468 may simply be an invocation of the indexSearchableItems( )method.","On subsequent loading of the app, the data indexer 460 may update the index data objects based on their continued relevancy, based on data changes made to the app, or based on rule changes from the business rules data store 464.For example, if cuisine names are being indexed, as new cuisine names are added to the app, the data indexer 460 may add the additional cuisine names to the operating system index.","Meanwhile, if the business rules data store 464 is updated to indicate that cuisine names should no longer be indexed, the data indexer 460 may delete the corresponding data objects from the operating system index.","A data store updater 472 is responsible for updating one or more data stores, including the breadcrumb data store 424, the index data store 416, and the business rules data store 464.The data store updater 472 contacts the data server 284 of FIG.","2 via a network interface 476.The network interface 476 may handle authentication and encryption so that the validity of data store updates can be confirmed.","The data store updater 472 may operate when the app incorporating the routing library 260 is first opened on a device and at subsequent periodic intervals.","In addition, the data store updater 472 may perform additional updates in response to data needs, such as if a breadcrumb ID is not present in the breadcrumb data store 424.An activity creator 480 creates activity objects to bookmark activities with the operating system.","The operating system interface 468 may bookmark an activity by calling the becomeCurrent( )method on a created activity object.","The activity creator 480 may respond to a view appearing, such as the viewDidAppear signal, or to some other event, such as the view loading or being about to appear.","The activity creator 480 may update activity objects as interactions with a view occur.","The activity creator 480 may, therefore, trap additional methods that provide user input to a view so that the corresponding activity object can be updated.","For example, as the user edits a textbox, the activity creator 480 may update the activity object after each keystroke.","In addition to creating an activity object, the activity creator 480 may indicate to the data indexer 460 that certain data objects should be indexed.","These decisions may be based on rules from the business rules data store 464.For example, the activity creator 480 may create an activity object based on the user viewing a list of restaurants for a particular cuisine.","Whether this activity object is created is determined by the business rules data store 464.The business rules data store 464 may also dictate that the activity creator 480 signal to the data indexer 460 that the top one or more results from a search should be indexed.","For example, if the user is viewing a set of Thai restaurants and the most relevant result is the Amarin Thai restaurant, the user may later wish to search for Amarin Thai.","By indexing the Amarin Thai data object, the operating system can provide a result directly to the app for Amarin Thai.","In addition, depending on how the operating system index identifies search results, a user searching within the operating system for “Thai” may see both the activity for the app related to a list of Thai restaurants as well as the specific Amarin Thai data object.","When the operating system sends a continue user activity signal related to one of the activity objects from the activity creator 480 or the data objects from the data indexer 460, a corresponding breadcrumb will be present in the breadcrumb data store 424 to reach these activity objects or data objects since the app itself was not programmed by the developer to accommodate them.","The activity objects and data objects created by the activity creator 480 and the data indexer 460 respectively are provided to the index data store 416 so that the index data store 416 is aware of which activity objects and data objects can be handled by the routing library 260 instead of being passed through the App A handler 300.A remote indexer 484 may be instructed by the business rules data store 464 to mirror activity objects and/or data objects from the index data store 416 to a remote index.","This remote index may be maintained by the provider of the routing library 260 or by a search service.","Activity objects and data objects may be marked with a private identifier (or assumed private unless marked with a public identifier).","This private identifier may prevent the object from being uploaded to the remote index or may prevent the object from being exposed by the remote index in public search results.","This privacy indication may be provided by the developer as part of the onboarding process of the app to the developer portal and may be updated by the developer over time.","A search system 288 receives access mechanisms from the data server 284 incorporating identifiers of breadcrumbs or the breadcrumbs themselves.","The search system 288 may already have information about states of interest of App A and then can associate the access mechanisms with the respective states.","In other implementations, the search system 288 may crawl and scrape App A to obtain metadata for states of interest, and may follow the access mechanisms to find the content of the states.","In one use model, the user of the user device 220 performs a search for certain functionality and/or for a certain entity, such as reviews for a restaurant of interest.","The user may perform this search with a standalone search app or, as shown in FIG.","2, a web search performed via the browser 228.The search system 288, as described in more detail below, provides search results to the browser 228.These results may include a result corresponding to App A 232, and may include a link indicating a specific deep state in App A 232.If the user selects the link corresponding to App A 232, the link is forwarded to the link router 244 and then passed to the routing library 260 of App A 232.App A 232 is then controlled by the routing library 260 to display the indicated deep state using the corresponding breadcrumb.","In various implementations, the routing library 260 receives the contents of the breadcrumb from parameters encoded within the link itself.","For example, the link (in this case, a URI) may include the scheme (“portal-appa://”) followed by a serialized encoding of each UI event of the breadcrumb in series leading to the desired view.","For example, the breadcrumb may be specified in a JSON (JavaScript Object Notation) data structure encoded using Base64.The search system 288 is, therefore, able to provide a link that will take the user directly to relevant content within App A 232.The search system 288 may provide search results to others apps.","For example, a hotels app may query the search system 288 for restaurants near the user's selected hotel and the search system 288 may provide restaurant search results to the hotels app.","In the case where App A 232 is a restaurant review app, the hotels app can link directly into a deep state of App A 232 corresponding to the restaurant of interest.","The search system 288 may provide the search results in the form of DVCs.","A DVC for an app or a state of an app shows additional information, beyond just the identification of the app or app state.","For example, the information may include a title of the app state or a description of the app state, which may be a snippet of text from the app state.","Other metadata may be provided from the app state, including images, location, number of reviews, average review, and status indicators.","For example, a status indicator of “open now” or “closed” may be applied to a business depending on whether the current time is within the operating hours of the business.","Some DVCs may emphasize information that led to the DVC being selected as a search result.","For example, text within the DVC that matches a user's query may be shown in bold or italics.","The DVC may also incorporate elements that allow direct actions, such as the ability to immediately call an establishment or to transition directly to a mapping app to get navigation directions to the establishment.","Other interactions with the DVC (such as tapping or clicking any other area of the DVC) may take the user to the indicated state or app.","As described in more detail below, this may be accomplished by opening the relevant app or, if the app is not installed, opening a website related to the desired app state.","In other implementations, an app that is not installed may be downloaded, installed, and then executed in order to reach the desired app state.","In other words, a DVC includes identifying information for the app or state as well as additional content from the app or state itself.","The additional content allows the user to make a more informed choice about which result to choose, and may even allow the user to directly perform an action without having to navigate to the app state.","If the action the user wants to take is to obtain information, in some circumstances the DVC itself may provide the necessary information to accomplish such action.","In various implementations, the routing library may be identical for each app with the only exception being the name of the custom scheme that the routing library will register upon installation.","The scheme may be formed by concatenating text of the developer portal with the text of the app name, and may include a separator such as a hyphen or an underscore.","The name of the app may change over time, but the scheme may be fixed after first being set to provide backward compatibility with older versions of the app whose routing library may only recognize the original scheme.","In various implementations, the routing library may be updated with security updates, bug fixes, and feature additions while maintaining backward compatibility.","Developers, such as the developer 204, may download and incorporate the newest version of the routing library each time they release a new version of their app to the digital distribution platform 212.In some implementations, the build/compile process may automatically download the latest version of the routing library when resolving linker dependencies.","The offline analysis system 280 may need to be invoked each time the developer 204 prepares a new version of App A for the digital distribution platform 212.In addition, as the developer 204 adds more content to App A, the offline analysis system 280 may be invoked to determine the breadcrumbs needed to access that added content.","Invocation of the offline analysis system 280 may be performed at the request of the developer 204 or may be performed on a periodic basis.","Any updates or additions to the breadcrumbs are stored by the data server 284 and can be provided to the search system 288 so that links within search results have the most up-to-date access mechanisms.","In some implementations, the breadcrumbs may be communicated to the routing library 260 using a mechanism other than direct inclusion in the URI.","For example, this may be necessary when a maximum-length link is shorter than the number of characters an encoded breadcrumb may require.","The routing library 260 may, therefore, in some implementations, download a package of breadcrumbs from the data server 284.Search results from the search system 288 or other links may then reference a unique identifier, which the routing library 260 maps to a breadcrumb.","For example only, the unique identifier may be formed from a function and an entity, such as “restaurant_reviews” and “Amarin_Thai”.","In one specific example, the URI “portal-appa://restaurant_reviews/Amarin_Thai” may be resolved by the routing library 260 to a breadcrumb that reaches the restaurant reviews state for the Amarin Thai restaurant from a default state of App A 232.However, there is no requirement that the unique identifier be human-readable.","In other implementations, the routing library 260 may consult the data server 284 in response to receiving a deep link.","By providing the unique identifier, the routing library 260 can download the necessary breadcrumb from the data server 284.In such implementations, the routing library 260 may cache breadcrumbs so that a network access isn't required to resolve deep links visited recently.","Pre-caching of some or all breadcrumbs may also be performed, such as when App A 232 first executes on the user device 220.Pre-caching may happen even earlier, such as when the developer 204 is preparing App A for distribution.","In other words, the full set or a subset of the breadcrumbs may be included along with App A so that when a unique identifier is received via a link, the appropriate breadcrumb can be chosen by the routing library 260 without delay.","Pre-caching may be combined with periodic verification of the breadcrumbs by the routing library 260, such as by checking a version number of the package of breadcrumbs at a periodic calendar interval, such as once a month.","In other implementations, the data server 284 may send a push notification to the routing library 260 indicating that new breadcrumbs are available.","To the extent that the developer 204 had implemented some deep links within App A, a developer-implemented router (not shown) in App A 232 would receive links from the link router 244.The developer's routing code would not have registered “portal-appa://” but instead a scheme independent of the developer portal 208, such as “appa.com://”.","In various implementations, the developer-specified URIs may not be publicly available or may only be available to companies with an established relationship with the developer 204.Some operating systems, including the iOS operating system, have a sandbox infrastructure to limit the extent to which an app can access resources or areas of memory beyond what has been specifically allocated to the app.","Sandboxing enhances security, making it more difficult for malicious software to compromise a user system.","Because the routing library 260 executes within the context of App A 232, the sandbox should pose no difficulty for interactions between the routing library 260 and the view controllers responsible for the views 268.High-Level Flowchart In FIG.","5, an overview of the operation of the present disclosure with respect to one developer and one app begins at 504.The developer first develops the app (referred to here as “App A”).","App A may not have functionality that can expose deep links to all of its states.","In addition, App A may not have indexing functionality or activity resumption functionality for some or all states.","Further, any deep linking or search functionality that App A possesses may require programmer intervention to modify.","As a result, the developer could benefit from the routing library described by the present invention.","At 508, the developer provides a copy of App A to the developer portal.","This may be a standard build, such as what would be provided to a digital distribution platform.","In fact, if App A has already been released to a digital distribution platform, the developer portal may acquire the copy of App A from the digital distribution platform.","While the standard build is generally restricted to running on emulators or hardware devices, the developer could instead provide a special build of App A, such as a build tailored to a simulation environment.","The simulation environment may even run on a different architecture (such as an x86 architecture) compared to the app (which may run on user device hardware based on the ARM architecture).","At 512, control begins offline analysis of App A. Offline analysis may include determining states for which deep links are already present in App A. Offline analysis may also include determining which activities can be resumed within App A in which data can be indexed by App A based on code written by the developer.","For example only, offline analysis may include static and dynamic analysis of App A, which is described in more detail in U.S. application Ser.","No.","14/984,642, filed Dec. 30, 2015, titled “Static Analysis and Reconstruction of Deep Link Handling and Compiled Applications,” with first-named inventor Kalyan Desineni, and having attorney docket no.","17100-000030-US.","The entire disclosure of this application is incorporated by reference.","At 516, the developer specifies business rules for App A.","For example, the developer specifies to the developer portal which states of App A to provide deep link functionality for, which activities of App A to bookmark, and what data to index.","The developer may navigate a copy of App A in order to specify which states to provide deep links for.","For example, the developer may interact with App A in a simulator, while the offline analysis platform monitors the user interface events for later replay.","The developer may simply be asked to navigate to states of interest, without needing to understand that the user interface events are being recorded for deep linking purposes.","For each state the developer navigates to, the developer may specify whether one or more activities being performed in that state should be bookmarked and may identify one or more pieces of data to index from that state.","The developer may specify what metadata to include with the data being indexed, and may flag activities or data as public or private.","At 520, in parallel with offline analysis, control provides a copy of the routing library from the developer portal to the developer.","At 524, the developer integrates the routing library into App A.","For example, this may include adding references in a configuration file to the scheme handled by the linking capability of the routing library as well as adding the types of activities that the routing library will recognize.","In some implementations, the activities recognized by the routing library will be redundant with activities already recognized by App A, such as when App A already allows for some activity resumption or data indexing.","The developer also links the binary to the App A project within the integrated development environment.","In various implementations, a script may be provided to the developer to perform the incorporation actions of 524.At 528, the developer compiles App A, which now includes the routing library, and provides App A to one or more digital distribution platforms.","At 532, a user of a user device installs App A from a digital distribution platform.","At 536, as part of installation, the routing library of App A registers a custom link scheme handled by the routing library as well as activity types handled by the routing library.","For example, this registration may be performed by the operating system based on a configuration file, such as Info.plist.","At 540, the routing library of the now-installed application updates access mechanisms and business rules.","For example, the access mechanisms may be breadcrumbs to reach certain states.","The business rules identify which states should be accessed, which activities should be bookmarked, and which data should be indexed.","When the application is first run, the routing library may download a full set of access mechanisms and business rules so that no access latency is incurred when an access mechanism or business rule is needed.","In other implementations, upon first being run, the routing library only downloads a subset of the access mechanisms, such as access mechanisms for the most popular states.","The updates at 540 may be performed each time the app is opened or at predetermined intervals.","In addition, the routing library may update access mechanisms and/or business rules if a required access mechanism (for example, a breadcrumb) is missing or if the access mechanism appears to not be working.","At 544, the routing library indexes data indicated by the developer according to the business rules.","For example, when the app first loads, the routing library may index a set of data indicated by the developer.","Then, as data is modified in App A, the routing library may update the operating system index based on the updated data.","At 548, the routing library bookmarks selected activities engaged by the user.","For example, when the user performs a search, the search criteria and filters may be bookmarked as an activity that the user can resume on that device or handoff to another device.","At 552, the routing library in App A handles proprietary App A links (indicated by the registered scheme) provided to the routing library from the operating system.","At 556, the routing library handles activities sent by the operating system, including continue user activity signals.","These activities may refer to bookmarked activities or to indexed data.","Control then returns to 540.Although 540, 544, 548, 552, and 556 are displayed in series, they may run asynchronously and in parallel.","Routing Library Operation In FIG.","6, example operation of the routing library is shown.","At 604, during installation of App A onto a device, the proprietary App A URI scheme and activity types in the routing library are registered.","This may be performed by the operating system from a configuration file (also known as a manifest file) as part of the installation process.","At 608, control requests breadcrumbs and configuration data from the data server.","This may be performed upon the first execution of App A on the user device.","At 612, control determines whether an activity or a proprietary App A URI has been received from the operating system.","If so, control transfers to 616; otherwise, control transfers to 620.At 616, control invokes a handler for the activity or proprietary App A URI.","For example, the handler may be implemented as shown in FIG.","7.For example only, the handler may respond to an openURL( ) call received by the operating system or from a continue user activity signal generated by the operating system.","After handling the activity or proprietary App A URI, control returns to 612.At 620, control determines whether an activity trigger event has occurred.","If so, control transfers to 624; otherwise, control transfers to 628.An activity trigger event may be the loading of a state or an action performed within a state.","The developer may specify which event qualifies as an activity trigger.","The developer may establish business rules dictating that some states trigger an activity when the state is entered while for other states an activity is bookmarked upon some further action being performed, such as user input.","At 624, control determines whether a breadcrumb is available to return to that activity.","If so, control transfers to 632; otherwise, control transfers to 636.If a breadcrumb that returns to that activity is not available, the routing library may not be able to resume that activity when requested by the operating system and therefore will not bookmark that activity.","At 632, the breadcrumb is available and therefore control sends an activity object to the operating system to bookmark the activity.","At 636, control determines whether the activity has been indicated by the developers as being public.","If so, control transfers to 640; otherwise, control continues at 628.At 640, the activity has been indicated as public and therefore control uploads the activity to a remote index.","Control then continues at 628.In other implementations, control may upload the activity to the remote index regardless of whether the activity has been indicated as public, and instead uses the public indicator to determine whether to reveal that activity to any users of the remote index.","At 628, control determines whether data should be indexed according to business rules established by the developer.","If so, control transfers to 644; otherwise, control transfers to 648.For example, when first running App A, there may be a predetermined set of data objects that the developer desires to index.","Then, after certain states have been accessed, the developer may have specified that data related to those states should be indexed.","For example, in a music streaming app, if the user has viewed a list of artists in a particular genre, data objects corresponding to each of the artists may be added to the operating system index.","At 644, if a breadcrumb is available for a data object the developer has indicated should be indexed, control transfers to 652; otherwise, control continues at 648.At 652, the breadcrumb to reach a state that can access that data object is available and therefore the data object is sent to the operating system.","If the breadcrumb were not available, the routing library would not be able to service a request from the operating system to display the data object to a user.","While FIG.","6 shows operation of the routing library, the developer may have implemented logic within App A that will index data objects and bookmark activities, separate from the routing library.","This indexing and bookmarking is not precluded by the operation of the routing library.","Therefore, even when the routing library does not index the data object or bookmarking activity, App A itself may be performing that task.","In order for App A to then resume the activity when instructed by the operating system, App A will have logic implemented by the developer to reach the appropriate states.","This logic may include direct actuation of view controllers or may include a user interface breadcrumb similar to that used by the routing library.","Control continues from 652 to 656, where if the data object is indicated as public, control transfers to 660; otherwise, control continues at 648.At 660, control uploads the data object to the remote index and continues at 648.Again, the public identifier may be ignored at the time of uploading the data object to the remote index and instead be taken into account when determining whether to reveal the data objects to other users.","At 648, control determines whether the last data update of breadcrumbs and configuration data is more than a predetermined time in the past.","If so, control transfers to 664 to update this data; otherwise, control returns to 612.Although shown as a predetermined amount of time, data updating may be performed dynamically based on how often the app is used, how often breadcrumbs or configuration data historically has changed, and/or may be based on a push signal from the data server indicating that data should be updated.","Activity/URI Handling In FIG.","7, example routing library operation for handling activities and proprietary URIs is shown.","In various implementations, the process of FIG.","7 may be called by 616 of FIG.","6.Control begins at 704, where if a proprietary App A URI has been received, control transfers to 708; otherwise, control transfers to 712.At 708, control determines whether the URI corresponds to a preexisting data object—that is, a data object that App A was able to index and display independent of the routing library.","If the URI corresponds to such a preexisting data object, control continues at 716; otherwise, control transfers to 720.At 716, the routing library will be able to use the preexisting access mechanism within App A to display a state relevant to that data object.","To accomplish this, control may prepare an activity request that is similar or identical to the activity request the operating system would provide to App A in order to display a state related to that data object.","Control then continues at 724, where the prepared activity request is passed to a preexisting App A handler that was written by the developer independent of the routing library.","Control then continues at 712.At 720, control determines whether the URI corresponds to a preexisting activity—that is, an activity that App A could bookmark and resume independent of the routing library.","If so, control transfers to 728; otherwise, control transfers to 732.At 728, control prepares an activity request identifying that preexisting activity.","The activity request may be similar or identical to a request that the operating system would provide to App A in order to resume the bookmarked activity.","The control then continues at 724.At 732, control determines whether the URI corresponds to a breadcrumb.","If so, control transfers to 736; otherwise, control transfers to 740.Although referred to as a breadcrumb, the access mechanism can be another mechanism the routing library uses to navigate to a certain state.","For example, the routing library may be programmed with a set of parameters allowing a specific view controller to be invoked with particular input parameters to arrive at a certain state.","At 736, control replays the breadcrumb, such as using a process shown in FIG.","8.Control then continues at 712.At 740, the proprietary App A URI cannot be passed to the preexisting App A handler and an access mechanism (such as a breadcrumb) does not exist.","As a result, error handling is performed.","For example, the error handling may include displaying a message to the user indicating that the link failed and directing the user to a default state of the app.","Before displaying the message, control may refresh downloaded breadcrumbs to ensure that the latest breadcrumbs are available.","As another example, control may attempt to find and then traverse a comparable URI, such as by querying a mapping of obsolete URIs to active URIs.","Control then continues at 712.At 712, if an activity request (such as a continue user activity method call) is received by App A (for example, by the App delegate of App A), control transfers to 744; otherwise, control transfers to 748.At 744, control determines whether the activity should be handled by the routing library.","If so, control transfers to 752; otherwise, control transfers to 756.At 752, the activity is handled by the routing library because the routing library bookmarked the corresponding activity or indexed the corresponding data object.","The activity may be resumed by replaying a breadcrumb corresponding to the state identified by the activity request.","For example, this may be performed as shown in FIG.","8.Control then returns to FIG.","6.At 756, if the routing library is aware that App A handles at least some activity requests, control continues at 760.Otherwise, if the routing library is confident that App A is otherwise unable to handle any activities, control transfers to 764 where error handling is performed.","For example, the error handling may include displaying an error message that the activity request cannot be met.","At 760, the activity request is passed through to the preexisting App A handler in the hope that the App A handler can handle the activity request.","Control then returns from FIG.","7.At 748, error handling is performed because neither a proprietary App A URI has been received or an activity request has been received.","Control may not be aware of what was received other than an activity request or a proprietary App A URI and therefore may not display anything to the user, instead simply taking the user to a default state of the app.","Control then returns from FIG.","7.Breadcrumb Traversal In FIG.","8, example operation of the routing library when traversing a breadcrumb is shown.","Control begins at 804, where if the breadcrumb is embedded in the URI, control transfers to 808; otherwise, control transfers to 812.As described above, breadcrumbs that allow the routing library to navigate to certain deep states may be received in links or may be indicated by unique ID in the link.","When indicated by a unique ID, the routing library may have to request the breadcrumb from a data server.","In some implementations, the routing library will therefore pre-cache some or all breadcrumbs.","This operation may be omitted if breadcrumbs will always be received within links.","In some implementations, certain breadcrumbs when encoded are longer than a maximum permitted length of a link.","This maximum length may be dictated by a browser, by an operating system, or by some other technological or business restriction.","These breadcrumbs may therefore be obtained from the data server, while shorter breadcrumbs are contained within URIs.","In this way, the generator of the URI (such as a search system) prepares the URI including the breadcrumb data itself when the maximum link length will not be exceeded, while otherwise including only a unique identifier of the breadcrumb.","At 808, control decodes a data structure holding the breadcrumb from the URI and control continues at 816.At 812, since the breadcrumb was not included in the URI, control determines whether the breadcrumb is already stored in the breadcrumb data store.","If so, control uses the breadcrumb from the breadcrumb data store and continues at 816; otherwise, control transfers to 820.At 820, control requests the breadcrumb from the data server, and when the breadcrumb is returned, control continues at 816.In various implementations, the routing library acquires an initial set of breadcrumbs before one of the breadcrumbs would be indicated by a URI.","For example, the routing library may be pre-packaged with the initial set of breadcrumbs or the routing library may download the initial set of breadcrumbs upon installation or first execution on the user device.","The routing library may periodically (for example, via a background process) receive new breadcrumbs to supplement functionality.","In some implementations, an improved user experience may result from breadcrumbs always being obtained from the data store and never retrieved from the data server.","This minimizes delays in response resulting from obtaining breadcrumbs from the data server and avoids availability issues from network connectivity problems.","At 816, control selects the first UI event in the sequence specified by the breadcrumb.","At 824, control replays the selected UI event from the breadcrumb.","At 828, control determines whether replaying the selected UI event successfully led to the next view or updated the current view as expected.","In various implementations, control may wait for a predetermined period of time before checking for success.","This predetermined period of time allows the app to respond to the UI event.","In various implementations, the breadcrumb data structure may include a specified wait time, which may apply to all UI events, or may have a separate wait time for each UI event.","As part of the breadcrumb determination process, the offline analysis system may detect that certain UI events take longer for an app to respond to.","In such cases, the offline analysis system may indicate that additional delay periods should be implemented before replaying another UI event.","At 828, success may instead be identified when the routing library detects that a method has been called with certain parameters corresponding to the replayed event.","In other words, as part of the offline analysis, the expected response to the app to a UI event may be recorded.","When this expected response is seen, success may be inferred.","If, at 828, the UI event appears to have been processed successfully, control transfers to 832; otherwise, control transfers to 836.At 836, control waits for another predetermined period of time.","This additional period of time may allow for unexpectedly slow response to a UI event.","Control continues at 840, where control once again attempts to verify that replaying the selected UI event has successfully led to the expected behavior.","If so, control continues at 832; otherwise, control transfers to 844.At 844, if the selected UI event has been replayed twice in an attempt to obtain a successful response, control transfers to 848.At 848, an error is declared.","For example, error handling may cause the app to revert to a home state and display a notification message to the user that the deep link was unsuccessful.","In addition, a message may be sent to the data server indicating that the deep link was unsuccessful.","Control then returns from FIG.","8.At 844, if the selected UI event has only been replayed a single time, there has not yet been a second failure, and therefore control returns to 824 to attempt to replay the selected UI event a second time.","In various implementations, success is not evaluated, and the UI events are replayed in series with the expectation that in most circumstances, the desired deep link will be reached.","As a result, elements 828, 836, 840, 844, and 848 may be replaced with a simple wait step.","The wait step may wait for a predetermined delay that has been empirically determined to allow the app to respond to user input.","The wait step may be used in systems where UI events cannot be processed by the app as quickly as they can be replayed by the routing library.","In other implementations, the wait step may involve watching for a method call resulting from the UI event.","Once response of the app to the UI event has been detected, such as by watching certain method calls, control may allow the following UI event to be replayed.","At 832, if there are additional UI events, control transfers to 852; otherwise, control returns from FIG.","8.At 852, control selects the next UI in the breadcrumb and returns to 824.Search System In FIG.","9, an example implementation of the search system 288 includes a search module 900.The search module 900 includes a query analysis module 904 that receives a query wrapper, which may take the form of a query string within a URL transmitted by the browser 228 of FIG.","2.The query analysis module 904 analyzes the text query from the query wrapper.","For example, the query analysis module 904 may tokenize the query text, filter the query text, and perform word stemming, synonymization, and stop word removal.","The query analysis module 904 may also analyze additional data stored within the query wrapper.","The query analysis module 904 provides the tokenized query to a set generation module 908.The set generation module 908 identifies a consideration set of application state records from a search data store 910 based on the query tokens.","Application (equivalently, app) state records correspond to specific states of apps.","In various implementations, the search data store 910 may also include app records.","In various implementations, an app record may be stored as an app state record that simply has a predetermined value, such as null, for the specific state of the app.","App state records in the search data store 910 may be generated by crawling and scraping apps according to the principles of the present disclosure.","Some or all of the contents of the records of the search data store 910 may be indexed in inverted indices.","In some implementations, the set generation module 908 uses the APACHE LUCENE software library by the Apache Software Foundation to identify records from the inverted indices.","The set generation module 908 may search the inverted indices to identify records containing one or more query tokens.","As the set generation module 908 identifies matching records, the set generation module 908 can include the unique ID of each identified record in the consideration set.","For example, the set generation module 908 may compare query terms to an app state name and app attributes (such as a text description and user reviews) of an app state record.","Further, in some implementations, the set generation module 908 may determine an initial score of the record with respect to the search query.","The initial score may indicate how well the contents of the record matched the query.","For example, the initial score may be a function of term frequency-inverse document frequency (TF-IDF) values of the respective query terms.","A set processing module 912 receives unique IDs of app state records identified by the set generation module 908 and determines a result score for some or all of the IDs.","A result score indicates the relevance of an app state with respect to the tokenized query and context parameters.","In various implementations, a higher score indicates a greater perceived relevance.","For example, other items in the query wrapper may act as context parameters.","Geolocation data may limit the score of (or simply remove altogether) apps that are not pertinent to the location of the user device.","A blacklist in the query wrapper may cause the set processing module 912 to remove app records and/or app state records from the consideration set that match the criteria in the blacklist, or to set their score to a null value, such as zero.","The set processing module 912 may generate a result score based on one or more scoring features, such as record scoring features, query scoring features, and record-query scoring features.","Example record scoring features may be based on measurements associated with the record, such as how often the record is retrieved during searches and how often links generated based on the record are selected by a user.","Query scoring features may include, but are not limited to, the number of words in the search query, the popularity of the search query, and the expected frequency of the words in the search query.","Record-query scoring features may include parameters that indicate how well the terms of the search query match the terms of the record indicated by the corresponding ID.","The set processing module 912 may include one or more machine-learned models (such as a supervised learning model) configured to receive one or more scoring features.","The one or more machine-learned models may generate result scores based on at least one of the record scoring features, the query scoring features, and the record-query scoring features.","For example, the set processing module 912 may pair the search query with each app state ID and calculate a vector of features for each {query, ID} pair.","The vector of features may include one or more record scoring features, one or more query scoring features, and one or more record-query scoring features.","In some implementations, the set processing module 912 normalizes the scoring features in the feature vector.","The set processing module 912 can set non-pertinent features to a null value or zero.","The set processing module 912 may then input the feature vector for one of the app state IDs into a machine-learned regression model to calculate a result score for the ID.","In some examples, the machine-learned regression model may include a set of decision trees (such as gradient-boosted decision trees).","Additionally or alternatively, the machine-learned regression model may include a logistic probability formula.","In some implementations, the machine-learned task can be framed as a semi-supervised learning task, where a minority of the training data is labeled with human-curated scores and the rest are used without human labels.","The machine-learned model outputs a result score of the ID.","The set processing module 912 can calculate result scores for each of the IDs that the set processing module 912 receives.","The set processing module 912 associates the result scores with the respective IDs and outputs the most relevant scored IDs.","A results generation module 924 may choose specific access mechanisms from the application records and app state records chosen by the set processing module 912.The results generation module 924 then prepares a results set to return to the user device.","Although called “app state results” here, some of the access mechanisms may correspond to a default state (such as a home page) of an app—these may be a special case of an app state record or may be an app record.","The results generation module 924 may select an access mechanism for an app state record based on whether the app is installed on the device.","If the app is installed, an access mechanism that opens the app directly to the specified state is selected.","Meanwhile, if the app is not installed, a selected access mechanism first downloads and installs the app, such as via a script, before opening the app to the specified state.","Opening the app to the specified state may include a single command or data structure (such as an intent in the ANDROID operating system) that directly actuates the specified state.","For other apps, a script or other sequence may be used to open the app to a certain state (such as a home, or default, state) and then navigate to the specified state.","The results generation module 924 may generate or modify access mechanisms based on the operating system identity and version for the user device to which the results are being transmitted.","For example, a script to download, install, open, and navigate to a designated state may be fully formed for a specific operating system by the results generation module 924.If the results generation module 924 determines that none of the native access mechanisms are likely to be compatible with the user device, the search module 900 may send a web access mechanism to the user device.","If no web access mechanism is available, or would be incompatible with the user device for some reason (for example, if the web access mechanism relies on the JAVA programming language, which is not installed on the user device), the results generation module 924 may omit the result.","Server-Side Control In FIG.","10, operation of server-side components may be performed within a single device or may be performed across the developer portal 208, the offline analysis system 280, the data server 284, and the search system 288 of FIG.","2.In various implementations, the developer portal 208, the data server 284, and the search system 288 may be under the control of the same entity.","The offline analysis system 280 may employ operators that facilitate static analysis and/or dynamic analysis to ensure that accurate and complete parameters are extracted from each app.","Control begins at 1002, where the routing library is made available to app developers.","Over time, the routing library may be updated, and the most up-to-date version may be the only one available to app developers.","At 1004, if a request for a breadcrumb has been received, control transfers to 1006; otherwise, control transfers to 1008.At 1006, control determines a subset of the breadcrumbs that has changed since the last request was received from the requester.","This subset can then be provided at 1010 to bring the data up-to-date at the source of the request.","Control then returns to 1004.At 1008, if offline processing of an app has been initiated, control transfers to 1012; otherwise, control transfers to 1016.At 1016, if a search query has been received from a search system, control transfers to 1020; otherwise, control returns to 1004.At 1020, control determines a consideration set of results corresponding to the search query.","This consideration set may include apps that are open to the search query as well as specific states (deep states) of apps that are relevant to the search query.","At 1024, control scores the elements in the consideration set based on how closely they match the understood intent of the search query.","The scored results can then be ranked from most relevant to least relevant.","At 1028, the highest-ranked results are formatted as deep view cards associated with deep links to the specific states within the results.","At 1032, control returns the deep view cards to the requestor of the query.","The deep view cards may not be fully rendered, and instead include images, text, and instructions on how to render the deep view cards for particular screen sizes, orientations, and other requirements of the requesting application or operating system.","For apps where the deep links are serviced by a routing library according to the principles of the present disclosure, an access mechanism returned along with the corresponding search result may include a URI with an encoded data structure.","The encoded data structure may include the breadcrumb necessary to invoke that specific state from within the app.","The URI, being a string, includes a serialized version of that data structure and is prefixed with a scheme.","The scheme, such as “portal-appa://”, will cause the URI to be forwarded to and recognized by the routing library of the app.","Control then returns to 1004.At 1012, control runs App A, such as in a simulator.","While App A is running, control monitors UI events resulting from the operator's usage of App A.","At 1036, control allows an operator to interact with App A to reach a deep state of interest, recording each UI interaction to form a breadcrumb.","In various implementations, control may monitor how long it takes App A to respond to certain UI events.","These response times, or delays based on the response times, may be encoded in the breadcrumb along with the corresponding UI events.","For example, some operations may require App A to obtain data from a server, incurring network communication delays.","When replaying the UI events in the breadcrumb, there should be a longer delay after the UI event leading to network access before the next UI event is replayed.","At 1040, if there are additional deep states of interest, control returns to 1036; otherwise, control continues at 1044.At 1044, control determines states that are parallel to the states identified by the operator.","For example, if the operator selects a link from a list of similar-looking items, and the selected link leads to a state of interest, control may assume that the other items in the list are also of interest.","These parallel states, and the breadcrumbs used to reach them (in the list example, the breadcrumbs would differ only in the last UI event), are added to the list of deep-linkable states.","In various implementations, App A may be exercised using a crawling algorithm to reach some or all deep states of App A.","For additional information regarding crawling, see U.S. patent application Ser.","No.","14/849,540, filed Sep. 9, 2015, titled “Unguided Application Crawling Architecture,” with first-named inventor Kalyan Desineni, and having Attorney Docket No.","17100-000006-US-01.The entire disclosure of this application is incorporated by reference.","At 1048, control provides a list of deep-linkable states to a search system for indexing.","At 1052, for each deep-linkable state, control provides a data structure containing the breadcrumb to the data server to be used in a URI as an access mechanism to access the deep state.","Control then returns to 1004.At 1012, an operator interacts with a copy of the app, such as in a simulator, to navigate to states of interest.","In some implementations, the operator navigates to states of interest designated by the developer; in other implementations, the developer herself navigates to states of interest.","User interface events required to reach various states are recorded such as described in FIG.","12.Control continues at 1040, where control may extrapolate additional states of interest from the operator-identified states of interest.","Example operation for extrapolation is shown in FIG.","13.At 1012, while the operator is identifying states of interest, the operator may also be tagging states as activities to be bookmarked and may be identifying data within the states as data objects to index.","Control continues at 1056, where configuration parameters established by the operator are transmitted to the data server.","For example, configuration parameters may be business rules specifying which states should be deep linked which states should be bookmarked as activities, and what data should be indexed.","Offline Analysis In FIG.","11, an example implementation of the offline analysis system 280 includes a guide creation system 1100 that allows for operator interaction with an app of interest (such as App A).","The guide creation system 1100 allows an operator to specify which states of an app should be deep-linkable and may use input from the operator to determine how to reach those deep states.","In various implementations, the operator is an administrator of the offline analysis system 280, acting on standard operating procedures for offline processing of an app or on instructions from a developer of the app.","Additionally or alternatively, an agent of the app developer may act as the operator.","The agent may specify which states or types of states should be made accessible as deep states.","After the initial offline analysis, the agent may use the developer portal 208 to request that additional states of the app be added as deep states and request that existing deep-linked states be removed.","This may be done via the developer portal 208 with no need for the agent to modify code of the app or even request assistance from the app's software developers.","In other words, marketing personnel or user experience designers may themselves control the scope of the deep linking within the app, without even releasing a new version of the app.","For added states, the offline analysis system 280 will re-process the app to determine the breadcrumbs to the added states.","For an app being processed by the offline analysis system 280, the operator controls a copy of the app of interest executing within a simulator 1104.In various other implementations, the app of interest may be installed on a physical device or executed in an emulation environment.","In various implementations, the simulator 1104 may be instantiated at a cloud hosting operator that may provide compute facilities within which to execute emulator/simulator code or that may directly provide emulators or simulators for one or more mobile device operating systems.","For more information, see U.S. patent application Ser.","No.","14/868,294, filed Sep. 28, 2015, titled “Operator-Guided Application Crawling Architecture,” with first-named inventor Kalyan Desineni, and having Attorney Docket No.","17100-000006-US-02.The entire disclosure of this application is incorporated by reference.","In some implementations, a physical device running the operating system may be used instead of the simulator 1104, such as for an operating system that does not have a suitable simulator or emulator.","The physical device may be connected to the guide creation system 1100 using a wireless or wired interface, such as USB (universal serial bus).","A root-level control application may be installed on the physical device to track user input.","Installing the root-level application may require bypassing security limitations of the firmware or operating system regarding privileges of installed apps and may require that the device be jailbroken.","Jailbreaking involves bypassing or removing various software restrictions imposed by the operating system and/or device firmware, and may be accomplished using a privilege escalation technique.","The jailbroken device may be further modified with pre-installed and specific settings that enable the techniques of the present disclosure, such as recording UI interactions.","The simulator 1104 is essentially already jailbroken.","However, the simulator 1104 may also be modified to allow for better control, such as to more easily allow recording UI interactions.","The operator's interaction with the app may be recorded to form a guide indicating how a state is reached.","This guide defines the breadcrumb used to reach the end state, and subsets of the guide define the breadcrumbs for intermediate states.","The guide may also be used to infer other states of interest and determine breadcrumbs leading to those states.","Each UI event may be associated with a specific UI element, identified according to a predetermined rubric by a unique ID.","For example, the unique ID may be dictated by how the UI elements are programmatically created when rendering the view.","In other implementations, the unique ID may be dictated by how the UI elements are actually seen, with the UI elements numbered in increasing order from left to right and top to bottom.","In other implementations, x-y coordinates may be used to identify the location of the user interaction, or the boundaries of the UI element actuated, or a center of the UI element actuated even if the operator's action was off-center.","In various implementations, static analysis may be used to analyze the UI elements of various states of the app.","Static analysis involves analyzing the code of the app without making observations of the app being executed.","In some implementations, a static analyzer (not shown) may identify the UI elements of each view and assign unique identifiers to each UI element within a view.","Then, dynamic analysis would have a predetermined nomenclature when referring to user interactions with any UI elements.","For example, static analysis may be performed with a disassembler and debugger implemented by the IDA Pro software from Hex-Rays SA.","Additionally or alternatively, the static analyzer may analyze the methods and views of an app to determine how best to instrument the app.","With this information, the dynamic analyzer can hook to the correct methods and listen for the correct events to accurately track user interaction with the app and discard method calls unrelated to user interaction.","For more information on static analysis, see U.S. patent application Ser.","No.","14/843,929, filed Sep. 2, 2015, titled “Static Analysis-Assisted Dynamic Application Crawling Architecture,” with first-named inventor Kalyan Desineni, and having Attorney Docket No.","17100-000006-US.","The entire disclosure of this application is incorporated by reference.","While the app is running in the simulator 1104, the guide creation system 1100 may monitor the messaging queue of the simulator 1104 (or of the actual operating system when executing in an emulator or physical device), listening for messages indicative of user manipulation of the app.","Such manipulation includes, for example, clicking, pressing, pinching, or swiping of the user interface.","In addition to capturing a unique identifier for each UI element the operator interacts with, the guide creation system 1100 may also extract the type of each element according to the defined types specified by the operating system, and further extract the identity of the associated view controller.","For example, the following methods may be hooked, such as by using method swizzling: (void)sendEvent:(UIEvent *)event method in the UIApplication class (void)sendAction:(SEL)action to:(id)target forEvent:(UIEvent *)event in UIControl class (void)viewDidAppear:(BOOL)animated for all the controllers that were loaded A handler may be implemented to record each type of UI element.","As an example, code for recording a button press can be implemented as follows: -(void)sendEvent:(UIEvent *)event { for (UITouch *touch in event.allTouches) { if (touch.phase == UITouchPhaseBegan) { if ([touch.view isKindOfClass:[UIButton class]]) { NSLog(@“UIButton:id:{%@}”, [((UIButton *)touch.view) currentTitle]); } } } } Other types of UI elements may be recorded by similar handler code.","In various implementations, after hooking the objc_msgSend function, a guide tracker 1108 may listen to the AppDelegate class and the (BOOL) application:(id)application ˜didFinishLaunchingWith Options: ˜(NSDictionary *)launchOptions method.","Further, the guide tracker 1108 may dynamically create listeners for controllers.","Instead of trying to exhaustively discover every state of an app through an unguided crawl of the app, the operator can help focus the analysis on the states for which deep links are desired—generally, the most interesting or important states.","The operator may begin at a home state of the app and progress to one state of interest for each category of states for which deep linking is desired.","The offline analysis system 280 may then extrapolate to find similar/parallel actions, each of which may correspond to another state of interest.","These parallel states can be added to a state list that defines which states will have corresponding breadcrumbs stored.","For example, if the app includes information about restaurants, the operator may browse to a state that lists restaurants, and then select one of the restaurants.","The operator may stop after finding a state that shows details about a first restaurant.","Based on the series of actions taken by the operator during browsing, the offline analysis system 280 can find other restaurant detail states that could have been reached in a similar way.","For example, after selecting a restaurant item with a certain layout and certain properties (e.g.","an image with property X next to a text box with property Y) from a list, the offline analysis system 280 may detect multiple additional restaurant items (that have the same layout and/or properties) within that view, which the operator could have selected.","It may then predict that selecting the other restaurant listings will result in finding additional restaurant info states.","For additional information about extrapolation, see U.S. patent application Ser.","No.","14/869,127, filed Sep. 29, 2015, titled “State Extrapolation for Automated and Semi-Automated Crawling Architecture,” with first-named inventor Kalyan Desineni, and having Attorney Docket No.","17100-000006-US-03.The entire disclosure of this application is incorporated by reference.","Within the guide creation system 1100, the guide tracker 1108 records operator interaction with the app in the simulator 1104 to create operator-specified guides.","For example, a guide may include each user interface interaction performed by the operator, beginning at the home (or, default) state of the app.","In various implementations, a target state tracker 1112 may allow the operator to flag a state currently visible in the simulator 1104 as a state of interest.","For example, the target state tracker 1112 may provide a user interface element (such as a button) within the simulator 1104 or as part of software through which the operator controls the simulator 1104.For each state of interest, a link extraction controller 1116 generates a breadcrumb specifying a sequence of UI events that leads to the state of interest.","The link extraction controller 1116 is aware of states that are of interest to the operator, either explicitly (such as via the target state tracker 1112) or implicitly (such as via the guide tracker 1108).","The link extraction controller 1116 may attempt to identify similar states—for example, states that are reached using similar UI (user interface) elements.","Target states may be explicitly identified by the operator using the target state tracker 1112.If target states are not specified by the operator, the link extraction controller 1116 may assume that the final state reached when an operator is creating a guide is the target state.","Alternatively, the link extraction controller 1116 may make the assumption that every state the operator navigated to should be a target state.","A deduplication procedure may be used to detect when the operator has browsed in a loop, thus avoiding recording duplicative and/or non-shortest-path guides.","Deduplication may be less necessary if the operator is explicitly marking target states.","The link extraction controller 1116 operates a simulator 1120, which, as described above, could instead be an emulator or a physical device.","For scale, multiple emulators, simulators, and/or physical devices may be controlled by the link extraction controller 1116 to analyze the same or different applications.","As an example only, a bank of physical smailphones may all be connected via USB to an interface card that is controlled by the link extraction controller 1116.Simply for ease of illustration, a single simulator (the simulator 1120) is shown in FIG.","4.In various implementations, the simulator 1120 and the simulator 1104 may be a single simulator shared by the guide creation system 1100 and the link extraction controller 1116.The application of interest is executed within the simulator 1120.In various implementations, the app executed by the simulator 1120 may be supplemented with a routing library, such as is described in FIG.","3A or FIG.","3B.","With the routing library, the link extraction controller 1116 can cause the app in the simulator 1120 to replay UI events to follow guides and identify additional states of interest.","In other implementations, because the app in the simulator 1120 does not need to be a publicly-distributed version of the app, an accessibility or automation framework may be used to perform UI control.","The routing library may be reserved for the version of the app that is publicly distributed.","The link extraction controller 1116 identifies states of interest corresponding to each of the guides specified by the guide tracker 1108.In order to reach a state within the app, the link extraction controller 1116 sends the shortest path specified by the guide tracker 1108 to the simulator 1120 to be replayed.","The link extraction controller 1116 identifies states of interest corresponding to each of the guides specified by the guide tracker 1108.In various implementations, the offline analysis system 280 may include a scraper (not shown) that extracts content from each state of interest.","The content may include text, images, and metadata, such as location, formatting, interface hints, etc.","This content may be used by the search system 288 of FIG.","2 to determine which deep states of the app are relevant to a search query.","In other implementations, the search system 288 may crawl and scrape the app separately, but may use the breadcrumbs from the offline analysis system 280 to navigate to the various states.","If there are UI fields into which text needs to be entered, the operator may identify to the guide creation system 1100 what types of textual input need to be entered.","The types could be, for example, city names, cuisine names, etc.","The link extraction controller 1116 then consults a knowledge base to get a list of possible values of such types (for cities, the list might include “Seattle,” “San Jose,” etc.)","and then replay each one of these values into the textual input field.","The link extraction controller 1116 may detect that a potential state of interest has already been reached by following a different breadcrumb.","The link extraction controller 1116 may then select one of the breadcrumbs to associate with that state.","For example, the breadcrumb having the fewest number of UI events may be selected.","Alternatively, the breadcrumb having the fewest view changes may be selected, and total number of UI events may be used as a tiebreaker.","To identify that a state has already been reached, the link extraction controller 1116 may store a fingerprint for each state along with the breadcrumb.","The fingerprint may be a reduced representation of the components of a state.","For example, a representation of visible objects may be created, such as by enumerating the objects in an XML data structure and then computing a mathematical hash (such as with MD5) of the data structure.","The hash is then the fingerprint, and if the hash of a new state matches a hash of an existing state, the states are considered to be the same.","As the link extraction controller 1116 assembles the set of states of interest, the link extraction controller 1116 may store an identifier of the state into a configuration data store 1124.For each state of interest, the link extraction controller 1116 determines a breadcrumb to reach that state and stores the breadcrumb in the configuration data store 1124.In addition, content or a fingerprint from states is stored in the configuration data store 1124.Data from the configuration data store 1124 may be provided to the search system 288 of FIG.","2.Breadcrumb Creation In FIG.","12, example operation of breadcrumb creation by an operator begins at 1204, where control opens the subject app in an emulator or simulator to the home state of the app.","At 1208, control begins tracking user interaction with the app, including tracking the user interface elements with which the operator interacts.","At 1212, if the operator marks the current state as a deep link target, control transfers to 1216; otherwise, control transfers to 1220.At 1216, the state is added to a list of target states and control continues at 1224.At 1224, control stores the operator interaction leading to the present state as a breadcrumb.","Control continues at 1220.At 1220, if the operator marks the state as an activity for bookmarking purposes, control transfers to 1228; otherwise, control transfers to 1232.At 1228, control adds the state to the rules for activity bookmarking so that when the state is encountered by a user, an activity corresponding to that state is bookmarked by sending an activity object to the operating system.","Control continues at 1236, where the operator interaction leading to the present state is stored as a breadcrumb.","If the breadcrumb was already stored at 1224 for the present state, an additional copy of the breadcrumb may be omitted from storage.","Control continues at 1232.At 1232, control continues tracking operator interaction with the app.","At 1240, control determines whether the operator has instructed the app to reset to a home state of the app.","If so, control transfers to 1244; otherwise, control returns to 1212.Resetting the home state may be accomplished by a user interface element belonging to the simulator within which the app is operating.","In other limitations, the app itself may have a mechanism for returning to the home state and this is recognized by 1240 as well.","By resetting to the home state, the operator indicates that a new set of user interface events should be tracked to lead to another state of interest.","At 1244, if the present state was not already marked as a deep link target, control stores the operator interaction leading to the present state as a breadcrumb and adds the present state to the list of target states.","Control continues at 1248, where if the operator is done, control ends.","Otherwise, control returns to 1208.Breadcrumb Extrapolation Referring to FIG.","13, the operator may have established a series of breadcrumbs but not labeled any particular states as target states.","For example, in some implementations, the operator may not be presented with an option to designate target states.","However, operator-created breadcrumbs generally begin at a home state and end at a terminal (or, final) state.","This final state may be assumed to be the state of interest for deep-linking.","In other words, only terminal states are assumed to be target states.","In other implementations, each state encountered along a breadcrumb is assumed to be a target state.","For example, when an operator is creating breadcrumbs for a restaurant review application, the operator may create one breadcrumb by navigating from the home state to a state containing restaurant information and reviews.","This would be assumed to be a desired target state, and the link extraction controller would attempt to find additional states that have similar data for scraping.","Control begins at 1304, where a first breadcrumb from a list of operator-created breadcrumbs is selected.","At 1308, control opens the app to a home state in an emulator.","At 1312, control follows the selected breadcrumb, stopping in the state immediately before the final state.","At 1316, control performs extrapolation to identify states similar to the final state.","For example, control identifies UI widgets parallel to the UI widget that, when followed according to the selected breadcrumb, will reach the final state.","At 1320, control adds the final state, as well as states reached from UI widgets identified as parallel, to a state list.","Each of the added states is annotated with a breadcrumb based on the selected breadcrumb.","The breadcrumb for the states other than the final state will diverge from the breadcrumb for the final state at the final UI event of each breadcrumb.","At 1324, control determines whether additional breadcrumbs are present in the list of breadcrumbs.","If so, control transfers to 1328; otherwise, control ends.","At 1328, control selects the next breadcrumb from the list of breadcrumbs and returns to 1308.CONCLUSION The

(referred to interchangeably in this disclosure as an “app”), such as a mobile app, may contain multiple deep states.\",\n \"For example, in an app that rates the quality of restaurants based on social media opinion data, the detail page for each restaurant would be considered a deep state.\",\n \"Deep states are reachable from within the app through a sequence of user actions that can involve navigating through multiple menu screens (or, views) as well as interactions with user interface elements.\",\n \"Each of these menu screens and user interface elements can be mediated by a unique view controller associated with that displayed screen.\",\n \"Usually, these deep states are accessible only from within the app itself web search engines operating outside the app, for example, cannot reach the deep states within the app.\",\n \"This means that when a user conducts a conventional web search for restaurants and wants to explore one of the returned choices in a specialized restaurant rating app, the user would have to manually copy and paste the name of the selected search result into the search field of the restaurant rating app and command the restaurant ranking app to access its internal deep state corresponding to the selected restaurant.\",\n \"This represents undesirable additional interaction required of the user.\",\n \"If deep states of apps could be exposed to external apps and computer processes, the user could enjoy additional functionality and convenience.\",\n \"For example, the user could begin a search for a suitable restaurant using an Internet-based search server and then, by selecting one of the results of that search, be automatically led to the appropriate deep linked page of a specialized restaurant ranking app.\",\n \"However, implementing such functionality requires developer effort and requires deep linking expertise that the developer may not possess.\",\n \"When app development is limited by time, budget, or expertise, deep link functionality for some or even all of the states of an app may not be a high enough priority to get implemented.\",\n \"Mobile operating systems, such as the iOS operating system from Apple Inc. and the Android operating system from Google Inc., may allow a developer to provide data to the operating system for indexing.\",\n \"In the iOS operating system, this may take the form of a CSSearchableItem (where the CS stands for Core Spotlight) object.\",\n \"The developer may implement code that bookmarks certain states of an app by providing information about those states to the operating system.\",\n \"In the iOS operating system, this may take the form of an NSUserActivity object (where NS stands for NeXTSTEP).\",\n \"Then, users can perform a search through the operating system, where relevant data or states from the developer's app are identified.\",\n \"If a user selects one of those activities from an operating system interface, such as a search dialogue or a recent tasks menu, the developer's code can restore the app to the state corresponding to the bookmarked activity.\",\n \"A bookmarked activity on a first device may even be continued on a different device (assuming the app is also installed on the other device).\",\n \"Via inter-device communication, the operating system of the first device notifies the operating system of the other device what state the user was most recently interacting with.\",\n \"In addition, the developer may specify that certain types of data, such as telephone numbers and names from a contact database maintained by the app, be indexed by the operating system.\",\n \"When a user indicates to the operating system that one of those data objects (for example, a certain contact) is of interest, the developer's code can transition to a state of the app that presents that data object for viewing or editing.\",\n \"In order to take advantage of these operating system capabilities, the developer may implement code that can restore the app to a state based on indicated activity or data object.\",\n \"However, these activities and data objects may be known only to the operating system or to search systems maintained by a developer of the operating system.\",\n \"In other words, third party apps and search services may be unable to access this data and navigate directly to the states or data objects within the app.\",\n \"Further, developing code to display data objects, index data objects, bookmark activities, and continue activities requires developer effort and may not be accomplished for any of an app's states much less for all of the app's states.\",\n \"As a result, these enhanced operating system capabilities may not be available for a variety of states of an app and may also not be accessible to third party apps and search systems.\",\n \"In FIG.\",\n \"1 , the enhanced operating system functionality is graphically depicted.\",\n \"On a user device, an operating system 100 executes a first app (referred to as “App A”) 104 .\",\n \"App A 104 includes a representative set of views, View A 108 - 1 , View B 108 - 2 , View C 108 - 3 , View D 108 - 4 , and View E 108 - 5 (collectively, views 108 ).\",\n \"The views 108 may be managed by one or more view controllers, which may be developed according to the model-view-controller (MVC) software architecture pattern.\",\n \"As an example only, App A 104 is a restaurant information app, View A 108 - 1 is a home (or, default) state of App A 104 from which restaurant searches by cuisine, geography, etc.\",\n \"can be performed.\",\n \"Continuing the example, View B 108 - 2 is a two-dimensional app interface showing restaurant locations, View C 108 - 3 is a restaurant detail view, View D 108 - 4 is a list of restaurants by cuisine, and View E 108 - 5 is a list of recently-reviewed restaurants.\",\n \"In various implementations, including this example, a single view may be a template populated with entity-specific data.\",\n \"For example, View C 108 - 3 may have a visual layout for a restaurant specifying where a photo of the restaurant will be located, the location, size, and font face of the restaurant's name, how reviews will be summarized, etc.\",\n \"The visual layout view will be instantiated with data corresponding to a specific restaurant from a data store.\",\n \"App A 104 selects and provides data objects to the operating system 100 for indexing.\",\n \"For example, App A 104 may provide the names of each of the specific cuisines encompassed by App A 104 .\",\n \"The operating system 100 can then provide results to users who are searching by that cuisine name.\",\n \"App A 104 includes an activity handler 112 that receives a continue user activity signal from the operating system 100 .\",\n \"For example, the continue user activity signal may specify that a certain cuisine type was of interest to a user.\",\n \"The activity handler 112 then invokes View D 108 - 4 and populates View D 108 - 4 with results corresponding to the specified cuisine.\",\n \"App A 104 may be selective regarding which cuisines to provide to the operating system 100 for indexing because providing too many data objects may lead to a decrease in their average relevance.\",\n \"This may cause the operating system 100 to down-rank or even remove indexed objects from search results that do not appear to have high relevance.\",\n \"App A 104 may, therefore, include programming that indexes a list of the most popular cuisines or cuisines whose names are more likely to be unique to cuisines.\",\n \"For example, while “American” may be a cuisine name, there is a high false positive rate because this term applies to many other searches than simply cuisine.\",\n \"However, if a user indicates interest in a cuisine, such as by reviewing the restaurant listings for a certain cuisine one or more times, App A 104 may add that cuisine name to the list of objects to index by the operating system 100 .\",\n \"In addition, App A 104 may indicate to the operating system 100 , using an activity object, that a user is currently viewing restaurant results for a particular cuisine.\",\n \"This allows the operating system 100 to maintain essentially a history of activities performed by the user within App A 104 .\",\n \"In addition, the most recent activity engaged in by the user can be shared with another device, allowing a hand-off of user interaction with that activity from one device to another.\",\n \"Submitting an activity object to the operating system, allowing later resumption of the activity on the same or another device, is referred to in this disclosure as bookmarking the activity.\",\n \"Activity objects may be sent to the operating system 100 when the user enters View B 108 - 2 to view restaurant results in a map display.\",\n \"For example, the activity object sent to the operating system 100 may include a latitude and longitude at a center of the map.\",\n \"If the user adjusts the center of the map, App A 104 may provide an updated activity object to the operating system 100 indicating the new center point.\",\n \"App A 104 may further include in the activity object additional data such as filters.\",\n \"For example, the user may have restricted the displayed results to only those restaurants that are currently open.\",\n \"This filter may be identified in the activity object provided to the operating system 100 .\",\n \"The activity handler 112 may receive a continue user activity signal from the operating system 100 indicating that the user is interested in continuing a map view of restaurants at a certain center point with a certain set of filters.\",\n \"For example only, in the iOS operating system, this may take the form of a continueUserActivity call to the app delegate of the app.\",\n \"The activity handler 112 then invokes View B 108 - 2 with the provided parameters and presents the user with the desired map view.\",\n \"The continue user activity signal may have been received from another device on which the user was previously viewing that map display.\",\n \"As shown in FIG.\",\n \"1 , the activity handler 112 is programmed to invoke View B 108 - 2 , View D 108 - 4 , and View E 108 - 5 , but not View A 108 - 1 or View C 108 - 3 .\",\n \"In the operating system 100 , a search index 120 receives data objects from App A 104 .\",\n \"The search index 120 also receives data objects from other apps and, in some implementations, from the operating system 100 itself, such as the names of frequently-accessed device settings.\",\n \"For example only, in the iOS operating system, the search index 120 may be referred to as Spotlight and the data objects provided to the search index 120 may take the form of CSSearchableItem objects.\",\n \"The search index 120 may also receive activity metadata from an activity tracker 124 .\",\n \"The activity tracker 124 receives activity objects, including from App A 104 .\",\n \"An activity object may take the form of an NSUserActivity object.\",\n \"An activity object received by the activity tracker 124 may include metadata similar to that of a data object.\",\n \"The metadata can be indexed by the search index 120 .\",\n \"The metadata may take the form of a CSSearchableItemAttributeSet object, which may be the same form used in CSSearchableItem objects.\",\n \"Activities indicated as public may be shared with a cloud index maintained by the developer of the operating system 100 .\",\n \"A cloud index interface 128 provides the public activities to the cloud index.\",\n \"These public activities are selectively indexed by the cloud index, allowing other users to search for and find activities generated by App A 104 even when App A 104 is not installed on their devices.\",\n \"A handoff controller 132 shares the latest activity with other devices.\",\n \"In various implementations, the other devices have been authenticated to the handoff controller 132 to indicate that they have permission to receive the latest activities from the present device.\",\n \"These other devices can, therefore, allow a user to begin an activity on the device where the operating system 100 is executed and resume the activity on another device.\",\n \"A search interface 136 allows a user to perform a search, such as by entering a text query.\",\n \"The search index 120 provides relevant search results to the search interface 136 and, upon a user selection, the user-selected result is provided to the activity tracker 124 .\",\n \"The activity tracker 124 identifies which app corresponds to the user-selected result and sends a continue user activity signal to the relevant app.\",\n \"The continue user activity signal may include an indicator whether the continue user activity signal pertains to a data object or an activity object.\"\n ],\n [\n \" SUMMARY A mobile application development system includes a

app's states.\",\n \"As a result, these enhanced operating system capabilities may not be available for a variety of states of an app and may also not be accessible to third party apps and search systems.\",\n \"In FIG.\",\n \"1, the enhanced operating system functionality is graphically depicted.\",\n \"On a user device, an operating system 100 executes a first app (referred to as “App A”) 104.App A 104 includes a representative set of views, View A 108-1, View B 108-2, View C 108-3, View D 108-4, and View E 108-5 (collectively, views 108).\",\n \"The views 108 may be managed by one or more view controllers, which may be developed according to the model-view-controller (MVC) software architecture pattern.\",\n \"As an example only, App A 104 is a restaurant information app, View A 108-1 is a home (or, default) state of App A 104 from which restaurant searches by cuisine, geography, etc.\",\n \"can be performed.\",\n \"Continuing the example, View B 108-2 is a two-dimensional app interface showing restaurant locations, View C 108-3 is a restaurant detail view, View D 108-4 is a list of restaurants by cuisine, and View E 108-5 is a list of recently-reviewed restaurants.\",\n \"In various implementations, including this example, a single view may be a template populated with entity-specific data.\",\n \"For example, View C 108-3 may have a visual layout for a restaurant specifying where a photo of the restaurant will be located, the location, size, and font face of the restaurant's name, how reviews will be summarized, etc.\",\n \"The visual layout view will be instantiated with data corresponding to a specific restaurant from a data store.\",\n \"App A 104 selects and provides data objects to the operating system 100 for indexing.\",\n \"For example, App A 104 may provide the names of each of the specific cuisines encompassed by App A 104.The operating system 100 can then provide results to users who are searching by that cuisine name.\",\n \"App A 104 includes an activity handler 112 that receives a continue user activity signal from the operating system 100.For example, the continue user activity signal may specify that a certain cuisine type was of interest to a user.\",\n \"The activity handler 112 then invokes View D 108-4 and populates View D 108-4 with results corresponding to the specified cuisine.\",\n \"App A 104 may be selective regarding which cuisines to provide to the operating system 100 for indexing because providing too many data objects may lead to a decrease in their average relevance.\",\n \"This may cause the operating system 100 to down-rank or even remove indexed objects from search results that do not appear to have high relevance.\",\n \"App A 104 may, therefore, include programming that indexes a list of the most popular cuisines or cuisines whose names are more likely to be unique to cuisines.\",\n \"For example, while “American” may be a cuisine name, there is a high false positive rate because this term applies to many other searches than simply cuisine.\",\n \"However, if a user indicates interest in a cuisine, such as by reviewing the restaurant listings for a certain cuisine one or more times, App A 104 may add that cuisine name to the list of objects to index by the operating system 100.In addition, App A 104 may indicate to the operating system 100, using an activity object, that a user is currently viewing restaurant results for a particular cuisine.\",\n \"This allows the operating system 100 to maintain essentially a history of activities performed by the user within App A 104.In addition, the most recent activity engaged in by the user can be shared with another device, allowing a hand-off of user interaction with that activity from one device to another.\",\n \"Submitting an activity object to the operating system, allowing later resumption of the activity on the same or another device, is referred to in this disclosure as bookmarking the activity.\",\n \"Activity objects may be sent to the operating system 100 when the user enters View B 108-2 to view restaurant results in a map display.\",\n \"For example, the activity object sent to the operating system 100 may include a latitude and longitude at a center of the map.\",\n \"If the user adjusts the center of the map, App A 104 may provide an updated activity object to the operating system 100 indicating the new center point.\",\n \"App A 104 may further include in the activity object additional data such as filters.\",\n \"For example, the user may have restricted the displayed results to only those restaurants that are currently open.\",\n \"This filter may be identified in the activity object provided to the operating system 100.The activity handler 112 may receive a continue user activity signal from the operating system 100 indicating that the user is interested in continuing a map view of restaurants at a certain center point with a certain set of filters.\",\n \"For example only, in the iOS operating system, this may take the form of a continueUserActivity call to the app delegate of the app.\",\n \"The activity handler 112 then invokes View B 108-2 with the provided parameters and presents the user with the desired map view.\",\n \"The continue user activity signal may have been received from another device on which the user was previously viewing that map display.\",\n \"As shown in FIG.\",\n \"1, the activity handler 112 is programmed to invoke View B 108-2, View D 108-4, and View E 108-5, but not View A 108-1 or View C 108-3.In the operating system 100, a search index 120 receives data objects from App A 104.The search index 120 also receives data objects from other apps and, in some implementations, from the operating system 100 itself, such as the names of frequently-accessed device settings.\",\n \"For example only, in the iOS operating system, the search index 120 may be referred to as Spotlight and the data objects provided to the search index 120 may take the form of CSSearchableItem objects.\",\n \"The search index 120 may also receive activity metadata from an activity tracker 124.The activity tracker 124 receives activity objects, including from App A 104.An activity object may take the form of an NSUserActivity object.\",\n \"An activity object received by the activity tracker 124 may include metadata similar to that of a data object.\",\n \"The metadata can be indexed by the search index 120.The metadata may take the form of a CSSearchableItemAttributeSet object, which may be the same form used in CSSearchableItem objects.\",\n \"Activities indicated as public may be shared with a cloud index maintained by the developer of the operating system 100.A cloud index interface 128 provides the public activities to the cloud index.\",\n \"These public activities are selectively indexed by the cloud index, allowing other users to search for and find activities generated by App A 104 even when App A 104 is not installed on their devices.\",\n \"A handoff controller 132 shares the latest activity with other devices.\",\n \"In various implementations, the other devices have been authenticated to the handoff controller 132 to indicate that they have permission to receive the latest activities from the present device.\",\n \"These other devices can, therefore, allow a user to begin an activity on the device where the operating system 100 is executed and resume the activity on another device.\",\n \"A search interface 136 allows a user to perform a search, such as by entering a text query.\",\n \"The search index 120 provides relevant search results to the search interface 136 and, upon a user selection, the user-selected result is provided to the activity tracker 124.The activity tracker 124 identifies which app corresponds to the user-selected result and sends a continue user activity signal to the relevant app.\",\n \"The continue user activity signal may include an indicator whether the continue user activity signal pertains to a data object or an activity object.\",\n \"SUMMARY A mobile application development system includes a developer portal and

may write code to take advantage of operating system (OS) functionality that allows, in one example, an activity within the app to be bookmarked for the user to return to later or for the activity to be resumed on another of the user's devices.\",\n \"The developer may also write code that submits data to the OS for indexing so that the OS can surface the data, such as in response to an OS-wide search.\",\n \"In order to implement this functionality, the developer writes code that allows the app to resume to an activity indicated by the OS or to a state that interacts with a data object specified by the OS.\",\n \"In some implementations, the activity object received from the OS fully specifies the activity for the app to resume, even if this particular copy of the app has not performed that activity previously.\",\n \"Meanwhile, for data objects, some apps may be able to show a state of the app corresponding to a certain data object only if that data object has been stored by the present copy of the app.\",\n \"In other implementations, or for certain apps, certain data objects may fully specify the state to which the app should return to view that data object.\",\n \"This generally means that the data for the data object is either known by the app, accessible to the app, or provided to the app from the OS within the continue user activity request.\",\n \"For data objects that do not fully specify the state of an app, these data objects may be specific to the app where they were created, and cannot be accessed by other copies of the app.\",\n \"Even though the developer may have implemented, for some or all states and for some or all data objects, the ability to resume that activity or navigate to that data object, there may be no provision for third parties, such as search services or other apps, to directly link to those activities or data objects within the app.\",\n \"The present disclosure identifies activities implemented by the developer and provides a library that, when presented with an appropriate deep link, can invoke the internal activity handling of the app.\",\n \"This allows the developer's efforts in interacting with the OS to be leveraged to provide deep link access to third parties.\",\n \"For some apps, the developer may not have implemented OS search functionality for some states and for some data.\",\n \"For some apps, the developer may not have implemented that functionality for any states or any data.\",\n \"The present disclosure, therefore, describes how the developer can specify which states of an app should have this functionality enabled.\",\n \"The present disclosure describes how the application can be supplemented to enable this functionality for the app, such as by recording sequences of user interface events that can be replayed to reach deep states of the app.\",\n \"When a routing library according to the principles of the present disclosure is used to enable activity bookmarking and data indexing, the configuration of the routing library may be specified by the developer.\",\n \"In various implementations, an agent of the developer may be able to make configuration decisions, such as which states to bookmark and which data to index, and those configuration decisions are relayed to the routing library.\",\n \"In various implementations, the routing library may periodically update this configuration so that the developer can change the configuration even for apps already installed on devices.\",\n \"A developer portal may allow even non-programmers working with the developer to specify business rules.\",\n \"For example, a marketing or user experience professional at the developer may specify what data to submit to the OS for indexing in order to optimize the search relevancy of the app for a given OS.\",\n \"A developer portal according to the present disclosure provides a routing library to the developer for integration into an app, and that routing library implements the above functionality.\",\n \"For example, based on configuration data, the routing library may bookmark certain activities with the OS and may submit certain data objects for indexing to the OS.\",\n \"The configuration data may be generated at the time of onboarding the app, and may be generated manually, with artificial intelligence, or with operator-supplemented artificial intelligence.\",\n \"In addition, the routing library may service continuing activity requests from the OS, such as by executing a series of user interface events to return to the selective activity or to display the selected data.\",\n \"The routing library may also handle incoming links, such as from other apps or from browser instances.\",\n \"The routing library may take the form of a dynamic link library (DLL), a dylib, or a software development kit (SDK).\",\n \"The routing library may be downloaded by the developer and imported into the integrated development environment (IDE) of the developer, such as the Xcode IDE from Apple Inc.\",\n \"In some implementations, the routing library is either already compiled or includes make files and other configuration files allowing the routing library to be compiled.\",\n \"The developer may integrate the routing library simply by instructing the IDE to add the routing library to their app's project, such as by adding the routing library to an import list or to a list of included code modules.\",\n \"The developer may also need to update a configuration file to indicate that the routing library will handle certain uniform resource identifiers (URIs) or activity types.\",\n \"The configuration file may take the form of an information property list (Info.plist) file.\",\n \"In various implementations, a script may be provided along with the routing library that performs the configuration file update as well as the import of the routing library into the current IDE project.\",\n \"Meanwhile, the developer portal supplies the app to an offline analysis system that determines how to access states of interest.\",\n \"The states of interest may be specified by the app developer or determined by the developer portal.\",\n \"In brief, an offline analysis system of the developer portal determines what sequence of user interface (UI) actions a user would take to reach a state of interest.\",\n \"That UI action sequence can be replayed by the routing library within an app on a user's device to arrive at the state of interest.\",\n \"In other words, the routing library simulates the UI actions users would themselves perform to reach a deep state.\",\n \"By simulating the UI actions, the routing library avoids the user having to perform each UI action and will generally be far faster than a user manually performing the sequence of UI actions.\",\n \"The user may not even see some of the intermediate states when the routing library is navigating to the deep state of interest, or these intermediate states may only be visible briefly.\",\n \"The UI action sequences for the deep states of an app may be integrated into the app along with the routing library, or may be downloaded by the routing library once the app is installed.\",\n \"In some implementations, a UI action sequence can be encoded as part of a link designating the app and serviced by the routing library.\",\n \"Without further effort from the developer, the app now has deep link functionality that can be accessed from external sources.\",\n \"For example, a search system could provide results that lead directly to deep states of the app.\",\n \"Or a third party app could easily direct users to deep states of the app.\",\n \"This may increase the visibility of the app and allow for tighter integration and better overall user experience with the app.\",\n \"In addition, now that the developer portal is responsible for deep linking, deep links can be added or modified without requiring assistance from the developer's software programmers, who may be working on other projects and have other priorities.\",\n \"In other words, a business person, such as an advertising or marketing professional working for an app developer, may use the developer portal to identify which states of the app should be deep-linkable.\",\n \"The business person could even remove states from the list of deep-linked states, all without requiring the assistance of a software programmer.\",\n \"Block Diagram In FIG.\",\n \"2, additional details are presented.\",\n \"As noted above, a developer 204 provides an app (referred to as “App A”) to a developer portal 208.The developer portal 208 provides a copy of a routing library to the developer 204 for incorporation into App A, creating an augmented version of App A.\",\n \"The developer 204 provides the augmented App A, which is still referred to below as App A for simplicity, to a digital distribution platform 212 for distribution to end users.\",\n \"The digital distribution platform 212 provides native apps to user devices and may be specific to an OS.\",\n \"Example digital distribution platforms include the GOOGLE PLAY digital distribution platform by Google, Inc., the APP STORE digital distribution platform by Apple, Inc., and the WINDOWS PHONE digital distribution platform by Microsoft Corp.\",\n \"If the developer 204 had already provided App A to the digital distribution platform 212 before augmentation with the routing library, the developer 204 can release the augmented App A as a new version of App A.\",\n \"The user of a user device 220 installs App A (as augmented) from the digital distribution platform 212.In the user device 220, one or more processors (which may encompass general purpose processors as well as additional co-processors, such as physical sensor processors and graphics processors) execute instructions from memory.\",\n \"Some of these instructions correspond to an operating system 224, a browser 228, an installed copy of App A (referred to as App A 232), and a third party app (App B 236).\",\n \"The operating system 224 includes an installed app registry 240 and a link router 244.The link router 244 receives links, such as URLs (uniform resource locators) and URIs (uniform resource identifiers), and determines how to handle those links.\",\n \"Generally, the link router 244 handles a link by forwarding it to a registered receiver.\",\n \"The link router 244 checks the installed app registry 240 to determine whether an app has claimed a particular scheme, domain, or other filter that matches the link.\",\n \"If not, the link may be passed to the browser 228, which may have registered a set of schemes for protocols such as HTTP (hypertext transfer protocol), HTTPS (HTTP secure), FTP (file transfer protocol), Telnet, and Gopher.\",\n \"In some implementations, when the link specifies a web server address, the link router 244 may contact the web server to obtain a list of authorized apps.\",\n \"In this way, the link router 244 verifies that an app that has registered a certain domain is authorized by that domain to handle links.\",\n \"This prevents apps from commandeering links to which they're not eligible.\",\n \"If an app that has registered a domain is authorized by the web server host of that domain, the link router 244 can provide the link to the registered app.\",\n \"Routing library 260, received from the developer portal 208, causes App A 232 to register a specific scheme or domain with the installed app registry 240.The scheme may be based on an identifier of the developer portal 208 as well as an identifier of App A.\",\n \"For example, a test string associated with the developer portal 208 (such as “portal”) may be concatenated with a text string corresponding to App A (such as “appa”).\",\n \"As a specific example, the scheme registered by App A 232 may be “portal-appa://”.\",\n \"In other implementations, the text string associated with the developer portal 208 may not be human-readable.\",\n \"When the link router 244 receives a link, such as from the browser 228, where the scheme matches “portal-appa://”, the link router 244 forwards that link to App A 232, where the link is received and handled by the routing library 260.The routing library 260 parses the link and navigates to a deep state indicated by the link.\",\n \"For illustration only, in FIG.\",\n \"2, View A 268-1, View B 268-2, and View C 268-3 (collectively, views 268) are shown.\",\n \"In many apps, more than three views will be present.\",\n \"In various implementations, multiple or all views may be controlled by a single view controller.\",\n \"In other implementations, each view may be controlled by a separate view controller.\",\n \"For illustration only, the routing library 260 is shown simulating events from a predetermined UI event sequence identified by an example link.\",\n \"The link is received by the routing library 260 and corresponds to a deep state, specifically View C 268-3.The UI event sequence includes a first UI event, causing App A 232 to transition from View A 268-1 to View B 268-2, a second UI event, in which App A remains in View B 268-2, and then a third UI event, causing App A 232 to transition from View B 268-2 to View C 268-3.The routing library 260 would simulate these UI events in series.\",\n \"A search system 272 of the operating system 224 receives data and activity objects from the routing library 260.The routing library 260 provides the data objects for indexing and the activity objects for bookmarking.\",\n \"The search system 272 allows a user to search for data and/or activities from App A 232.When the user selects an activity corresponding to App A 232, the search system 272 sends an indication of a selected activity to the routing library 260.The search system 272 is shown in more detail in FIG.\",\n \"3A and FIG.\",\n \"3B.\",\n \"In parallel with providing the routing library from the developer portal 208 to the developer 204, the developer portal 208 provides App A to an offline analysis system 280.The copy of App A provided to the developer portal 208 may be a standard release build, such as an iOS App Store Package (ipa file).\",\n \"In other implementations, the copy of App A provided to the developer portal 208 may be a special build that allows App A to be run in a simulator, and may include symbols, debugging info, and/or source code that would not ordinarily be present in an app distributed by the digital distribution platform 212.This may allow the offline analysis system 280 to more efficiently or accurately analyze App A.\",\n \"For example, the copy of App A may be a debug build designed to run in the Simulator application from Apple, Inc. on the OS X operating system.\",\n \"By contrast, the version of App A distributed by the digital distribution platform 212 is a standard release build.\",\n \"The offline analysis system 280, as described in more detail below, determines UI event sequences that can be used by the routing library 260 to reach specific views of App A 232.A UI event sequence may be referred to as a breadcrumb trail composed of an ordered sequence of individual breadcrumbs (that is, UI events).\",\n \"For simplicity, in the remainder of this disclosure, the term breadcrumb will be used to refer to a breadcrumb trail.\",\n \"The offline analysis system 280 may provide the determined breadcrumbs to a data server 284.The data server 284 includes a data store, such as a relational database, that stores breadcrumbs for each app processed by the offline analysis system 280.Each deep state of an app is associated with a corresponding breadcrumb.\",\n \"In some implementations, the data server 284 may be implemented as a cloud-based block storage service, such as the S3 (Simple Storage Service) service available from Amazon Web Services.\",\n \"Access mechanisms define how deep states can be reached for such purposes as display advertisements and deep search results.\",\n \"For example, a search result may correspond to a specific deep state of an app.\",\n \"The search result may be a deep view card (DVC, see below) with a link including or indicating a breadcrumb corresponding to that deep state.\",\n \"Other potential access mechanisms for the search result may include a native deep link prepared by the app developer itself, or a standard URL pointing to a web edition of the app.\",\n \"One of the available access mechanisms may be selected by a search system and provided along with the search result to a search client.\",\n \"In other implementations, multiple access mechanisms may be provided within the search result, and the search client determines which access mechanism to use in response to user selection of the search result.\",\n \"For example, a breadcrumb-based access mechanism may be chosen over a web-based access mechanism when business rules indicate a preference for results to render in native apps instead of in web editions of those apps.\",\n \"The breadcrumb-based access mechanism, however, may only be available when the app is already installed.\",\n \"In some implementations, the search client may incorporate, or receive as part of the search result, code that scripts downloading and installing of the app, followed by actuation of a deep link.\",\n \"The deep link may be actuated by sending a breadcrumb-based URI to the newly-installed app.\",\n \"The data server 284 may also store configuration settings, such as which deep states to allow links to, which deep states to bookmark as activities, and which data to index.\",\n \"This configuration may be specified by the developer 204 using the developer portal 208.The data server 284 may also receive index items from the routing library 260.For example, the routing library 260 may report activity objects back to the data server 284.The data server 284 can then analyze user interaction with App A 232 and generate information about how to provide more relevant search results.\",\n \"In addition, data from the data server 284 may be provided back to the developer 204, essentially providing an easy way to instrument App A 232 to analyze user engagement.\",\n \"The data server 284 may correlate user activity across multiple apps on the user device 220, thereby further improving search results.\",\n \"Routing Library Integration with Application In FIG.\",\n \"3A, an example of App A 232 includes the routing library 260 and also includes an App A

various implementations, the search system 272 may include elements similar to those shown in the operating system 100 in FIG.\",\n \"1.The activity creator 304 may send activity objects to the search system 272 based on user activities associated with View B 268-2, View D 268-4, and View E 268-5.The App A handler 300 also interfaces with a data indexer 308, which may provide data objects to the search system 272 related to View B 268-2, View D 268-4, and View E 268-5.The routing library 260 is able to invoke View A 268-1 and View C 268-3 if the developer of App A 232 has requested that functionality through a developer portal.\",\n \"The routing library 260 may be able to access View A 268-1 and View C 268-3 by invoking respective view controllers, as described in more detail in

Events,” with first-named inventor Kalyan Desineni, and having attorney docket no.\",\n \"17100-000032-US.\",\n \"The entire disclosure of this application is incorporated by reference.\",\n \"While the activity creator 304 developed by the developer of App A 232 provides activity objects for some of the views 268 to the activity tracker 124, the routing library 260 is able to provide activity objects from others of the views 268.For example, the activity creator 304 may create an NSUserActivity object and invoke the becomeCurrent( ) method to provide the activity object to the activity tracker 124.It may be irrelevant to the activity tracker 124 whether the routing library or the App A handler 300 sent the activity object.\",\n \"When the activity tracker 124 sends a continue user activity signal to App A 232, the routing library 260 traps (such as by overloading, overriding, or swizzling the continue user activity method) the continue user activity signal.\",\n \"If the continue user activity signal is relevant to the App A handler 300, the continue user activity signal is passed through to the App A handler 300.Otherwise, the routing library 260 handles the continue user activity signal.\",\n \"Similarly, the routing library 260 and the data indexer 308 developed by the developer of App A 232 may each create CSSearchableItem objects and introduce them to the search index 120, such as by using the indexSearchableItems method.\",\n \"When the activity tracker 124 provides a continue user activity signal to the routing library 260 related to a data object, the routing library 260 either instantiates a view based on the selected data object or passes the continue user activity signal through to the App A handler 300.The NSUserActivity object may include a unique identifier (such as a title) and an activity type.\",\n \"In a continue user activity signal, the activity type may differentiate an NSUseractivity object from a CSSearchableItem object.\",\n \"The NSUserActivity object may also include a list of text keywords to allow the object to be indexed.\",\n \"The NSUserActivity object may also include a set of metadata, such as a CSSearchableItemAttributeSet, which may include an image and other information.\",\n \"The set of metadata for an object may be displayed when the object is included in a set of search results and gives the user information about whether the object satisfies their query.\",\n \"The CSSearchableItem object includes a unique identifier and a set of metadata, which may take the form of a CSSearchableItemAttributeSet.\",\n \"The CSSearchableItem object may also include an expiration date beyond which the object will be automatically de-indexed by the operating system.\",\n \"Further, the CSSearchableItem object may include a domain identifier to group related objects.\",\n \"In various implementations, the routing library 260 and the App A handler 300 may both be able to instantiate one or more of the views 268.For example, the App A handler 300 may be programmed to instruct the activity creator 304 to bookmark activities with respect to View B 268-2.Meanwhile, the routing library 260 may be programmed to submit data for indexing from View B 268-2.When a continue user activity signal is received by the routing library 260, if the continue user activity signal is related to a bookmarked activity, the routing library 260 passes through the continue user activity signal to the App A handler 300.Meanwhile, if the continue user activity signal for View B 268-2 is related to a data object, the routing library 260 itself navigates to View B 268-2 in order to display data related to the data object.\",\n \"Although not shown in FIG.\",\n \"3A, App A 232 may include an internal link router that receives deep links and instantiates views based on those deep links.\",\n \"For links including a scheme registered by the routing library 260, which is different than the scheme registered by the internal link router of App A 232, the routing library 260 receives the deep link and instantiates one of the views 268 based on the link.\",\n \"For example, the link may specify a breadcrumb to follow in order to arrive at the desired state.\",\n \"The routing library 260 may override methods invoked by the activity creator 304 and the data indexer 308 to pass activity objects and data objects to the search system 272.In this way, the routing library 260 can first inspect the activity objects and data objects before then passing the activity objects data objects to the search system 272.The routing library 260 will then be aware of which activity objects have been created by the activity creator 304, and can, therefore, service deep links related to those activity objects.\",\n \"Similarly, the routing library 260 will know which data objects have been indexed by the data indexer 308, and can then service deep links related to those data objects.\",\n \"In order to allow third party Apps and services to access App A 232 using those deep links, the routing library 260 may upload information from the activity objects and the data objects to a remote server.\",\n \"In order to service a deep link related to the activity objects from the activity creator 304 and the data objects from the data indexer 308, the routing library 260 can generate a continue user activity signal and send that signal to the App A handler 300.The App A handler 300 may be unaware that the continue user activity signal was received from the routing library 260 instead of from the search system 272.The App A handler 300 can then resume the activity or instantiate a review related to the index data as if the request came directly from the search system 272.In FIG.\",\n \"3B, another example app, App B 360, is shown.\",\n \"In App B 360, views 364-1, 364-2, 364-3, 364-4, and 364-5 (collectively, views 364) are shown for illustration.\",\n \"App B 360 does not include a built-in handler similar to the App A handler 300 of FIG.\",\n \"3A.\",\n \"As a result, in order to access any of the views 364, the routing library 260 includes mechanisms (such as breadcrumbs) to access each of the views 364.Further, the routing library 260 is solely responsible for generating activity objects and data objects to send to the search system 272.When a continue user activity signal is received by the routing library 260, the routing library 260 cannot pass the continue user activity signal through and instead is responsible for handling the resumption of an activity or a creation of a view related to a data object.\",\n \"Routing Library In FIG.\",\n \"4, an example implementation of the routing library 260 includes registration data 404.The registration data 404 indicates to the operating system that the routing library 260 will handle links having a scheme relating to the routing library 260 and will also handle continue user activity signals relating to the app in which the routing library 260 is incorporated.\",\n \"In various implementations, the registration data 404 is included in a configuration file of the app into which the routing library 260 is incorporated.\",\n \"A URI (uniform resource identifier) processor 408 receives a link from the operating system.\",\n \"For example, the link may have originated from a browser or from a third-party app.\",\n \"The URI processor 408 extracts a unique ID from the link, which may simply be the text within the URI to the right of the pair of forward slashes following the scheme.\",\n \"An internal router 412 consults an index data store 416 to determine whether the unique ID from the URI corresponds to a breadcrumb or corresponds to an activity call that will be made to the App A handler 300.In other words, the internal router 412 decides whether a breadcrumb exists to reach the state indicated by the unique ID or whether an activity call should be made to the App A handler 300 to reach the state indicated by the unique ID.\",\n \"When the internal router 412 determines the unique ID corresponds to a breadcrumb, the internal router 412 sends a breadcrumb ID to a state machine 420.In various implementations, the breadcrumb ID may be the same as the unique ID or may be different as defined by a mapping from the index data store 416.As described in more detail below, the state machine 420 retrieves a breadcrumb from a breadcrumb data store 424 and executes each user interface action within the breadcrumb using a UI replay actuator 428.The state machine 420 may monitor the state of App A 232 to ensure that each user interface event is processed by App A 232 before moving to the next UI event.\",\n \"If the internal router 412 determines that the unique ID from the URI processor 408 corresponds to an activity or data object handled by the App A handler 300, a signal is sent to an activity call creator 432.The activity call creator 432 creates a continue user activity signal specifying the activity or data object related to the link.\",\n \"The parameters required for creating the continue user activity signal may be obtained from the index data store 416.The continue user activity signal is passed to the App A handler 300 via a handler interface 436, which may send a continue user activity signal to the App A handler 300 as if the App A handler 300 was receiving that signal directly from the operating system.\",\n \"As mentioned above, the routing library 260 traps the method called by the operating system to provide a continue user activity signal to the app.\",\n \"An activity handler 440 of the routing library 260 then receives the continue user activity signal.\",\n \"The activity handler 440 determines whether the continue user activity signal should be handled by the App A handler 300 already implemented by the developer.\",\n \"This determination may be based on the index data store 416.In such cases, the activity handler 440 provides the continue user activity as a pass through to the App A handler 300 via the handler interface 436.In apps where the developer has not coded a handler such as the App A handler 300, the activity handler 440 may never transmit pass through activities and the activity call creator 432 and the handler interface 436 may be dormant.\",\n \"If the activity handler 440 determines that the continue user activity signal, according to the index data store 416, can be resumed using a stored breadcrumb, the breadcrumb ID is provided to the state machine 420 for execution.\",\n \"So far, the aspects of the routing library 260 related to incoming deep links, whether in the form of a link or a continue user activity signal from the operating system, have been described.\",\n \"The routing library 260 may also implement functionality that sends activity objects and data objects to the operating system.\",\n \"This allows the operating system to return search results from the app.\",\n \"A data indexer 460 determines which data objects of the app to index based on rules from a business rules data store 464.For example only, the data indexer 460 may respond to an app loaded signal to execute upon the app successfully running on the device.\",\n \"The data indexer 460 may, upon the first execution of the app, send a predetermined set of data objects to the operating system via an operating system interface 468.For example only, with respect to data objects, the operating system interface 468 may simply be an invocation of the indexSearchableItems( )method.\",\n \"On subsequent loading of the app, the data indexer 460 may update the index data objects based on their continued relevancy, based on data changes made to the app, or based on rule changes from the business rules data store 464.For example, if cuisine names are being indexed, as new cuisine names are added to the app, the data indexer 460 may add the additional cuisine names to the operating system index.\",\n \"Meanwhile, if the business rules data store 464 is updated to indicate that cuisine names should no longer be indexed, the data indexer 460 may delete the corresponding data objects from the operating system index.\",\n \"A data store updater 472 is responsible for updating one or more data stores, including the breadcrumb data store 424, the index data store 416, and the business rules data store 464.The data store updater 472 contacts the data server 284 of FIG.\",\n \"2 via a network interface 476.The network interface 476 may handle authentication and encryption so that the validity of data store updates can be confirmed.\",\n \"The data store updater 472 may operate when the app incorporating the routing library 260 is first opened on a device and at subsequent periodic intervals.\",\n \"In addition, the data store updater 472 may perform additional updates in response to data needs, such as if a breadcrumb ID is not present in the breadcrumb data store 424.An activity creator 480 creates activity objects to bookmark activities with the operating system.\",\n \"The operating system interface 468 may bookmark an activity by calling the becomeCurrent( )method on a created activity object.\",\n \"The activity creator 480 may respond to a view appearing, such as the viewDidAppear signal, or to some other event, such as the view loading or being about to appear.\",\n \"The activity creator 480 may update activity objects as interactions with a view occur.\",\n \"The activity creator 480 may, therefore, trap additional methods that provide user input to a view so that the corresponding activity object can be updated.\",\n \"For example, as the user edits a textbox, the activity creator 480 may update the activity object after each keystroke.\",\n \"In addition to creating an activity object, the activity creator 480 may indicate to the data indexer 460 that certain data objects should be indexed.\",\n \"These decisions may be based on rules from the business rules data store 464.For example, the activity creator 480 may create an activity object based on the user viewing a list of restaurants for a particular cuisine.\",\n \"Whether this activity object is created is determined by the business rules data store 464.The business rules data store 464 may also dictate that the activity creator 480 signal to the data indexer 460 that the top one or more results from a search should be indexed.\",\n \"For example, if the user is viewing a set of Thai restaurants and the most relevant result is the Amarin Thai restaurant, the user may later wish to search for Amarin Thai.\",\n \"By indexing the Amarin Thai data object, the operating system can provide a result directly to the app for Amarin Thai.\",\n \"In addition, depending on how the operating system index identifies search results, a user searching within the operating system for “Thai” may see both the activity for the app related to a list of Thai restaurants as well as the specific Amarin Thai data object.\",\n \"When the operating system sends a continue user activity signal related to one of the activity objects from the activity creator 480 or the data objects from the data indexer 460, a corresponding breadcrumb will be present in the breadcrumb data store 424 to reach these activity objects or data objects since the app itself was not programmed by the developer to accommodate them.\",\n \"The activity objects and data objects created by the activity creator 480 and the data indexer 460 respectively are provided to the index data store 416 so that the index data store 416 is aware of which activity objects and data objects can be handled by the routing library 260 instead of being passed through the App A handler 300.A remote indexer 484 may be instructed by the business rules data store 464 to mirror activity objects and/or data objects from the index data store 416 to a remote index.\",\n \"This remote index may be maintained by the provider of the routing library 260 or by a search service.\",\n \"Activity objects and data objects may be marked with a private identifier (or assumed private unless marked with a public identifier).\",\n \"This private identifier may prevent the object from being uploaded to the remote index or may prevent the object from being exposed by the remote index in public search results.\",\n \"This privacy indication may be provided by the developer as part of the onboarding process of the app to the developer portal and may be updated by the developer over time.\",\n \"A search system 288 receives access mechanisms from the data server 284 incorporating identifiers of breadcrumbs or the breadcrumbs themselves.\",\n \"The search system 288 may already have information about states of interest of App A and then can associate the access mechanisms with the respective states.\",\n \"In other implementations, the search system 288 may crawl and scrape App A to obtain metadata for states of interest, and may follow the access mechanisms to find the content of the states.\",\n \"In one use model, the user of the user device 220 performs a search for certain functionality and/or for a certain entity, such as reviews for a restaurant of interest.\",\n \"The user may perform this search with a standalone search app or, as shown in FIG.\",\n \"2, a web search performed via the browser 228.The search system 288, as described in more detail below, provides search results to the browser 228.These results may include a result corresponding to App A 232, and may include a link indicating a specific deep state in App A 232.If the user selects the link corresponding to App A 232, the link is forwarded to the link router 244 and then passed to the routing library 260 of App A 232.App A 232 is then controlled by the routing library 260 to display the indicated deep state using the corresponding breadcrumb.\",\n \"In various implementations, the routing library 260 receives the contents of the breadcrumb from parameters encoded within the link itself.\",\n \"For example, the link (in this case, a URI) may include the scheme (“portal-appa://”) followed by a serialized encoding of each UI event of the breadcrumb in series leading to the desired view.\",\n \"For example, the breadcrumb may be specified in a JSON (JavaScript Object Notation) data structure encoded using Base64.The search system 288 is, therefore, able to provide a link that will take the user directly to relevant content within App A 232.The search system 288 may provide search results to others apps.\",\n \"For example, a hotels app may query the search system 288 for restaurants near the user's selected hotel and the search system 288 may provide restaurant search results to the hotels app.\",\n \"In the case where App A 232 is a restaurant review app, the hotels app can link directly into a deep state of App A 232 corresponding to the restaurant of interest.\",\n \"The search system 288 may provide the search results in the form of DVCs.\",\n \"A DVC for an app or a state of an app shows additional information, beyond just the identification of the app or app state.\",\n \"For example, the information may include a title of the app state or a description of the app state, which may be a snippet of text from the app state.\",\n \"Other metadata may be provided from the app state, including images, location, number of reviews, average review, and status indicators.\",\n \"For example, a status indicator of “open now” or “closed” may be applied to a business depending on whether the current time is within the operating hours of the business.\",\n \"Some DVCs may emphasize information that led to the DVC being selected as a search result.\",\n \"For example, text within the DVC that matches a user's query may be shown in bold or italics.\",\n \"The DVC may also incorporate elements that allow direct actions, such as the ability to immediately call an establishment or to transition directly to a mapping app to get navigation directions to the establishment.\",\n \"Other interactions with the DVC (such as tapping or clicking any other area of the DVC) may take the user to the indicated state or app.\",\n \"As described in more detail below, this may be accomplished by opening the relevant app or, if the app is not installed, opening a website related to the desired app state.\",\n \"In other implementations, an app that is not installed may be downloaded, installed, and then executed in order to reach the desired app state.\",\n \"In other words, a DVC includes identifying information for the app or state as well as additional content from the app or state itself.\",\n \"The additional content allows the user to make a more informed choice about which result to choose, and may even allow the user to directly perform an action without having to navigate to the app state.\",\n \"If the action the user wants to take is to obtain information, in some circumstances the DVC itself may provide the necessary information to accomplish such action.\",\n \"In various implementations, the routing library may be identical for each app with the only exception being the name of the custom scheme that the routing library will register upon installation.\",\n \"The scheme may be formed by concatenating text of the developer portal with the text of the app name, and may include a separator such as a hyphen or an underscore.\",\n \"The name of the app may change over time, but the scheme may be fixed after first being set to provide backward compatibility with older versions of the app whose routing library may only recognize the original scheme.\",\n \"In various implementations, the routing library may be updated with security updates, bug fixes, and feature additions while maintaining backward compatibility.\",\n \"Developers, such as the developer 204, may download and incorporate the newest version of the routing library each time they release a new version of their app to the digital distribution platform 212.In some implementations, the build/compile process may automatically download the latest version of the routing library when resolving linker dependencies.\",\n \"The offline analysis system 280 may need to be invoked each time the developer 204 prepares a new version of App A for the digital distribution platform 212.In addition, as the developer 204 adds more content to App A, the offline analysis system 280 may be invoked to determine the breadcrumbs needed to access that added content.\",\n \"Invocation of the offline analysis system 280 may be performed at the request of the developer 204 or may be performed on a periodic basis.\",\n \"Any updates or additions to the breadcrumbs are stored by the data server 284 and can be provided to the search system 288 so that links within search results have the most up-to-date access mechanisms.\",\n \"In some implementations, the breadcrumbs may be communicated to the routing library 260 using a mechanism other than direct inclusion in the URI.\",\n \"For example, this may be necessary when a maximum-length link is shorter than the number of characters an encoded breadcrumb may require.\",\n \"The routing library 260 may, therefore, in some implementations, download a package of breadcrumbs from the data server 284.Search results from the search system 288 or other links may then reference a unique identifier, which the routing library 260 maps to a breadcrumb.\",\n \"For example only, the unique identifier may be formed from a function and an entity, such as “restaurant_reviews” and “Amarin_Thai”.\",\n \"In one specific example, the URI “portal-appa://restaurant_reviews/Amarin_Thai” may be resolved by the routing library 260 to a breadcrumb that reaches the restaurant reviews state for the Amarin Thai restaurant from a default state of App A 232.However, there is no requirement that the unique identifier be human-readable.\",\n \"In other implementations, the routing library 260 may consult the data server 284 in response to receiving a deep link.\",\n \"By providing the unique identifier, the routing library 260 can download the necessary breadcrumb from the data server 284.In such implementations, the routing library 260 may cache breadcrumbs so that a network access isn't required to resolve deep links visited recently.\",\n \"Pre-caching of some or all breadcrumbs may also be performed, such as when App A 232 first executes on the user device 220.Pre-caching may happen even earlier, such as when the developer 204 is preparing App A for distribution.\",\n \"In other words, the full set or a subset of the breadcrumbs may be included along with App A so that when a unique identifier is received via a link, the appropriate breadcrumb can be chosen by the routing library 260 without delay.\",\n \"Pre-caching may be combined with periodic verification of the breadcrumbs by the routing library 260, such as by checking a version number of the package of breadcrumbs at a periodic calendar interval, such as once a month.\",\n \"In other implementations, the data server 284 may send a push notification to the routing library 260 indicating that new breadcrumbs are available.\",\n \"To the extent that the developer 204 had implemented some deep links within App A, a developer-implemented router (not shown) in App A 232 would receive links from the link router 244.The developer's routing code would not have registered “portal-appa://” but instead a scheme independent of the developer portal 208, such as “appa.com://”.\",\n \"In various implementations, the developer-specified URIs may not be publicly available or may only be available to companies with an established relationship with the developer 204.Some operating systems, including the iOS operating system, have a sandbox infrastructure to limit the extent to which an app can access resources or areas of memory beyond what has been specifically allocated to the app.\",\n \"Sandboxing enhances security, making it more difficult for malicious software to compromise a user system.\",\n \"Because the routing library 260 executes within the context of App A 232, the sandbox should pose no difficulty for interactions between the routing library 260 and the view controllers responsible for the views 268.High-Level Flowchart In FIG.\",\n \"5, an overview of the operation of the present disclosure with respect to one developer and one app begins at 504.The developer first develops the app (referred to here as “App A”).\",\n \"App A may not have functionality that can expose deep links to all of its states.\",\n \"In addition, App A may not have indexing functionality or activity resumption functionality for some or all states.\",\n \"Further, any deep linking or search functionality that App A possesses may require programmer intervention to modify.\",\n \"As a result, the developer could benefit from the routing library described by the present invention.\",\n \"At 508, the developer provides a copy of App A to the developer portal.\",\n \"This may be a standard build, such as what would be provided to a digital distribution platform.\",\n \"In fact, if App A has already been released to a digital distribution platform, the developer portal may acquire the copy of App A from the digital distribution platform.\",\n \"While the standard build is generally restricted to running on emulators or hardware devices, the developer could instead provide a special build of App A, such as a build tailored to a simulation environment.\",\n \"The simulation environment may even run on a different architecture (such as an x86 architecture) compared to the app (which may run on user device hardware based on the ARM architecture).\",\n \"At 512, control begins offline analysis of App A. Offline analysis may include determining states for which deep links are already present in App A. Offline analysis may also include determining which activities can be resumed within App A in which data can be indexed by App A based on code written by the developer.\",\n \"For example only, offline analysis may include static and dynamic analysis of App A, which is described in more detail in U.S. application Ser.\",\n \"No.\",\n \"14/984,642, filed Dec. 30, 2015, titled “Static Analysis and Reconstruction of Deep Link Handling and Compiled Applications,” with first-named inventor Kalyan Desineni, and having attorney docket no.\",\n \"17100-000030-US.\",\n \"The entire disclosure of this application is incorporated by reference.\",\n \"At 516, the developer specifies business rules for App A.\",\n \"For example, the developer specifies to the developer portal which states of App A to provide deep link functionality for, which activities of App A to bookmark, and what data to index.\",\n \"The developer may navigate a copy of App A in order to specify which states to provide deep links for.\",\n \"For example, the developer may interact with App A in a simulator, while the offline analysis platform monitors the user interface events for later replay.\",\n \"The developer may simply be asked to navigate to states of interest, without needing to understand that the user interface events are being recorded for deep linking purposes.\",\n \"For each state the developer navigates to, the developer may specify whether one or more activities being performed in that state should be bookmarked and may identify one or more pieces of data to index from that state.\",\n \"The developer may specify what metadata to include with the data being indexed, and may flag activities or data as public or private.\",\n \"At 520, in parallel with offline analysis, control provides a copy of the routing library from the developer portal to the developer.\",\n \"At 524, the developer integrates the routing library into App A.\",\n \"For example, this may include adding references in a configuration file to the scheme handled by the linking capability of the routing library as well as adding the types of activities that the routing library will recognize.\",\n \"In some implementations, the activities recognized by the routing library will be redundant with activities already recognized by App A, such as when App A already allows for some activity resumption or data indexing.\",\n \"The developer also links the binary to the App A project within the integrated development environment.\",\n \"In various implementations, a script may be provided to the developer to perform the incorporation actions of 524.At 528, the developer compiles App A, which now includes the routing library, and provides App A to one or more digital distribution platforms.\",\n \"At 532, a user of a user device installs App A from a digital distribution platform.\",\n \"At 536, as part of installation, the routing library of App A registers a custom link scheme handled by the routing library as well as activity types handled by the routing library.\",\n \"For example, this registration may be performed by the operating system based on a configuration file, such as Info.plist.\",\n \"At 540, the routing library of the now-installed application updates access mechanisms and business rules.\",\n \"For example, the access mechanisms may be breadcrumbs to reach certain states.\",\n \"The business rules identify which states should be accessed, which activities should be bookmarked, and which data should be indexed.\",\n \"When the application is first run, the routing library may download a full set of access mechanisms and business rules so that no access latency is incurred when an access mechanism or business rule is needed.\",\n \"In other implementations, upon first being run, the routing library only downloads a subset of the access mechanisms, such as access mechanisms for the most popular states.\",\n \"The updates at 540 may be performed each time the app is opened or at predetermined intervals.\",\n \"In addition, the routing library may update access mechanisms and/or business rules if a required access mechanism (for example, a breadcrumb) is missing or if the access mechanism appears to not be working.\",\n \"At 544, the routing library indexes data indicated by the developer according to the business rules.\",\n \"For example, when the app first loads, the routing library may index a set of data indicated by the developer.\",\n \"Then, as data is modified in App A, the routing library may update the operating system index based on the updated data.\",\n \"At 548, the routing library bookmarks selected activities engaged by the user.\",\n \"For example, when the user performs a search, the search criteria and filters may be bookmarked as an activity that the user can resume on that device or handoff to another device.\",\n \"At 552, the routing library in App A handles proprietary App A links (indicated by the registered scheme) provided to the routing library from the operating system.\",\n \"At 556, the routing library handles activities sent by the operating system, including continue user activity signals.\",\n \"These activities may refer to bookmarked activities or to indexed data.\",\n \"Control then returns to 540.Although 540, 544, 548, 552, and 556 are displayed in series, they may run asynchronously and in parallel.\",\n \"Routing Library Operation In FIG.\",\n \"6, example operation of the routing library is shown.\",\n \"At 604, during installation of App A onto a device, the proprietary App A URI scheme and activity types in the routing library are registered.\",\n \"This may be performed by the operating system from a configuration file (also known as a manifest file) as part of the installation process.\",\n \"At 608, control requests breadcrumbs and configuration data from the data server.\",\n \"This may be performed upon the first execution of App A on the user device.\",\n \"At 612, control determines whether an activity or a proprietary App A URI has been received from the operating system.\",\n \"If so, control transfers to 616; otherwise, control transfers to 620.At 616, control invokes a handler for the activity or proprietary App A URI.\",\n \"For example, the handler may be implemented as shown in FIG.\",\n \"7.For example only, the handler may respond to an openURL( ) call received by the operating system or from a continue user activity signal generated by the operating system.\",\n \"After handling the activity or proprietary App A URI, control returns to 612.At 620, control determines whether an activity trigger event has occurred.\",\n \"If so, control transfers to 624; otherwise, control transfers to 628.An activity trigger event may be the loading of a state or an action performed within a state.\",\n \"The developer may specify which event qualifies as an activity trigger.\",\n \"The developer may establish business rules dictating that some states trigger an activity when the state is entered while for other states an activity is bookmarked upon some further action being performed, such as user input.\",\n \"At 624, control determines whether a breadcrumb is available to return to that activity.\",\n \"If so, control transfers to 632; otherwise, control transfers to 636.If a breadcrumb that returns to that activity is not available, the routing library may not be able to resume that activity when requested by the operating system and therefore will not bookmark that activity.\",\n \"At 632, the breadcrumb is available and therefore control sends an activity object to the operating system to bookmark the activity.\",\n \"At 636, control determines whether the activity has been indicated by the developers as being public.\",\n \"If so, control transfers to 640; otherwise, control continues at 628.At 640, the activity has been indicated as public and therefore control uploads the activity to a remote index.\",\n \"Control then continues at 628.In other implementations, control may upload the activity to the remote index regardless of whether the activity has been indicated as public, and instead uses the public indicator to determine whether to reveal that activity to any users of the remote index.\",\n \"At 628, control determines whether data should be indexed according to business rules established by the developer.\",\n \"If so, control transfers to 644; otherwise, control transfers to 648.For example, when first running App A, there may be a predetermined set of data objects that the developer desires to index.\",\n \"Then, after certain states have been accessed, the developer may have specified that data related to those states should be indexed.\",\n \"For example, in a music streaming app, if the user has viewed a list of artists in a particular genre, data objects corresponding to each of the artists may be added to the operating system index.\",\n \"At 644, if a breadcrumb is available for a data object the developer has indicated should be indexed, control transfers to 652; otherwise, control continues at 648.At 652, the breadcrumb to reach a state that can access that data object is available and therefore the data object is sent to the operating system.\",\n \"If the breadcrumb were not available, the routing library would not be able to service a request from the operating system to display the data object to a user.\",\n \"While FIG.\",\n \"6 shows operation of the routing library, the developer may have implemented logic within App A that will index data objects and bookmark activities, separate from the routing library.\",\n \"This indexing and bookmarking is not precluded by the operation of the routing library.\",\n \"Therefore, even when the routing library does not index the data object or bookmarking activity, App A itself may be performing that task.\",\n \"In order for App A to then resume the activity when instructed by the operating system, App A will have logic implemented by the developer to reach the appropriate states.\",\n \"This logic may include direct actuation of view controllers or may include a user interface breadcrumb similar to that used by the routing library.\",\n \"Control continues from 652 to 656, where if the data object is indicated as public, control transfers to 660; otherwise, control continues at 648.At 660, control uploads the data object to the remote index and continues at 648.Again, the public identifier may be ignored at the time of uploading the data object to the remote index and instead be taken into account when determining whether to reveal the data objects to other users.\",\n \"At 648, control determines whether the last data update of breadcrumbs and configuration data is more than a predetermined time in the past.\",\n \"If so, control transfers to 664 to update this data; otherwise, control returns to 612.Although shown as a predetermined amount of time, data updating may be performed dynamically based on how often the app is used, how often breadcrumbs or configuration data historically has changed, and/or may be based on a push signal from the data server indicating that data should be updated.\",\n \"Activity/URI Handling In FIG.\",\n \"7, example routing library operation for handling activities and proprietary URIs is shown.\",\n \"In various implementations, the process of FIG.\",\n \"7 may be called by 616 of FIG.\",\n \"6.Control begins at 704, where if a proprietary App A URI has been received, control transfers to 708; otherwise, control transfers to 712.At 708, control determines whether the URI corresponds to a preexisting data object—that is, a data object that App A was able to index and display independent of the routing library.\",\n \"If the URI corresponds to such a preexisting data object, control continues at 716; otherwise, control transfers to 720.At 716, the routing library will be able to use the preexisting access mechanism within App A to display a state relevant to that data object.\",\n \"To accomplish this, control may prepare an activity request that is similar or identical to the activity request the operating system would provide to App A in order to display a state related to that data object.\",\n \"Control then continues at 724, where the prepared activity request is passed to a preexisting App A handler that was written by the developer independent of the routing library.\",\n \"Control then continues at 712.At 720, control determines whether the URI corresponds to a preexisting activity—that is, an activity that App A could bookmark and resume independent of the routing library.\",\n \"If so, control transfers to 728; otherwise, control transfers to 732.At 728, control prepares an activity request identifying that preexisting activity.\",\n \"The activity request may be similar or identical to a request that the operating system would provide to App A in order to resume the bookmarked activity.\",\n \"The control then continues at 724.At 732, control determines whether the URI corresponds to a breadcrumb.\",\n \"If so, control transfers to 736; otherwise, control transfers to 740.Although referred to as a breadcrumb, the access mechanism can be another mechanism the routing library uses to navigate to a certain state.\",\n \"For example, the routing library may be programmed with a set of parameters allowing a specific view controller to be invoked with particular input parameters to arrive at a certain state.\",\n \"At 736, control replays the breadcrumb, such as using a process shown in FIG.\",\n \"8.Control then continues at 712.At 740, the proprietary App A URI cannot be passed to the preexisting App A handler and an access mechanism (such as a breadcrumb) does not exist.\",\n \"As a result, error handling is performed.\",\n \"For example, the error handling may include displaying a message to the user indicating that the link failed and directing the user to a default state of the app.\",\n \"Before displaying the message, control may refresh downloaded breadcrumbs to ensure that the latest breadcrumbs are available.\",\n \"As another example, control may attempt to find and then traverse a comparable URI, such as by querying a mapping of obsolete URIs to active URIs.\",\n \"Control then continues at 712.At 712, if an activity request (such as a continue user activity method call) is received by App A (for example, by the App delegate of App A), control transfers to 744; otherwise, control transfers to 748.At 744, control determines whether the activity should be handled by the routing library.\",\n \"If so, control transfers to 752; otherwise, control transfers to 756.At 752, the activity is handled by the routing library because the routing library bookmarked the corresponding activity or indexed the corresponding data object.\",\n \"The activity may be resumed by replaying a breadcrumb corresponding to the state identified by the activity request.\",\n \"For example, this may be performed as shown in FIG.\",\n \"8.Control then returns to FIG.\",\n \"6.At 756, if the routing library is aware that App A handles at least some activity requests, control continues at 760.Otherwise, if the routing library is confident that App A is otherwise unable to handle any activities, control transfers to 764 where error handling is performed.\",\n \"For example, the error handling may include displaying an error message that the activity request cannot be met.\",\n \"At 760, the activity request is passed through to the preexisting App A handler in the hope that the App A handler can handle the activity request.\",\n \"Control then returns from FIG.\",\n \"7.At 748, error handling is performed because neither a proprietary App A URI has been received or an activity request has been received.\",\n \"Control may not be aware of what was received other than an activity request or a proprietary App A URI and therefore may not display anything to the user, instead simply taking the user to a default state of the app.\",\n \"Control then returns from FIG.\",\n \"7.Breadcrumb Traversal In FIG.\",\n \"8, example operation of the routing library when traversing a breadcrumb is shown.\",\n \"Control begins at 804, where if the breadcrumb is embedded in the URI, control transfers to 808; otherwise, control transfers to 812.As described above, breadcrumbs that allow the routing library to navigate to certain deep states may be received in links or may be indicated by unique ID in the link.\",\n \"When indicated by a unique ID, the routing library may have to request the breadcrumb from a data server.\",\n \"In some implementations, the routing library will therefore pre-cache some or all breadcrumbs.\",\n \"This operation may be omitted if breadcrumbs will always be received within links.\",\n \"In some implementations, certain breadcrumbs when encoded are longer than a maximum permitted length of a link.\",\n \"This maximum length may be dictated by a browser, by an operating system, or by some other technological or business restriction.\",\n \"These breadcrumbs may therefore be obtained from the data server, while shorter breadcrumbs are contained within URIs.\",\n \"In this way, the generator of the URI (such as a search system) prepares the URI including the breadcrumb data itself when the maximum link length will not be exceeded, while otherwise including only a unique identifier of the breadcrumb.\",\n \"At 808, control decodes a data structure holding the breadcrumb from the URI and control continues at 816.At 812, since the breadcrumb was not included in the URI, control determines whether the breadcrumb is already stored in the breadcrumb data store.\",\n \"If so, control uses the breadcrumb from the breadcrumb data store and continues at 816; otherwise, control transfers to 820.At 820, control requests the breadcrumb from the data server, and when the breadcrumb is returned, control continues at 816.In various implementations, the routing library acquires an initial set of breadcrumbs before one of the breadcrumbs would be indicated by a URI.\",\n \"For example, the routing library may be pre-packaged with the initial set of breadcrumbs or the routing library may download the initial set of breadcrumbs upon installation or first execution on the user device.\",\n \"The routing library may periodically (for example, via a background process) receive new breadcrumbs to supplement functionality.\",\n \"In some implementations, an improved user experience may result from breadcrumbs always being obtained from the data store and never retrieved from the data server.\",\n \"This minimizes delays in response resulting from obtaining breadcrumbs from the data server and avoids availability issues from network connectivity problems.\",\n \"At 816, control selects the first UI event in the sequence specified by the breadcrumb.\",\n \"At 824, control replays the selected UI event from the breadcrumb.\",\n \"At 828, control determines whether replaying the selected UI event successfully led to the next view or updated the current view as expected.\",\n \"In various implementations, control may wait for a predetermined period of time before checking for success.\",\n \"This predetermined period of time allows the app to respond to the UI event.\",\n \"In various implementations, the breadcrumb data structure may include a specified wait time, which may apply to all UI events, or may have a separate wait time for each UI event.\",\n \"As part of the breadcrumb determination process, the offline analysis system may detect that certain UI events take longer for an app to respond to.\",\n \"In such cases, the offline analysis system may indicate that additional delay periods should be implemented before replaying another UI event.\",\n \"At 828, success may instead be identified when the routing library detects that a method has been called with certain parameters corresponding to the replayed event.\",\n \"In other words, as part of the offline analysis, the expected response to the app to a UI event may be recorded.\",\n \"When this expected response is seen, success may be inferred.\",\n \"If, at 828, the UI event appears to have been processed successfully, control transfers to 832; otherwise, control transfers to 836.At 836, control waits for another predetermined period of time.\",\n \"This additional period of time may allow for unexpectedly slow response to a UI event.\",\n \"Control continues at 840, where control once again attempts to verify that replaying the selected UI event has successfully led to the expected behavior.\",\n \"If so, control continues at 832; otherwise, control transfers to 844.At 844, if the selected UI event has been replayed twice in an attempt to obtain a successful response, control transfers to 848.At 848, an error is declared.\",\n \"For example, error handling may cause the app to revert to a home state and display a notification message to the user that the deep link was unsuccessful.\",\n \"In addition, a message may be sent to the data server indicating that the deep link was unsuccessful.\",\n \"Control then returns from FIG.\",\n \"8.At 844, if the selected UI event has only been replayed a single time, there has not yet been a second failure, and therefore control returns to 824 to attempt to replay the selected UI event a second time.\",\n \"In various implementations, success is not evaluated, and the UI events are replayed in series with the expectation that in most circumstances, the desired deep link will be reached.\",\n \"As a result, elements 828, 836, 840, 844, and 848 may be replaced with a simple wait step.\",\n \"The wait step may wait for a predetermined delay that has been empirically determined to allow the app to respond to user input.\",\n \"The wait step may be used in systems where UI events cannot be processed by the app as quickly as they can be replayed by the routing library.\",\n \"In other implementations, the wait step may involve watching for a method call resulting from the UI event.\",\n \"Once response of the app to the UI event has been detected, such as by watching certain method calls, control may allow the following UI event to be replayed.\",\n \"At 832, if there are additional UI events, control transfers to 852; otherwise, control returns from FIG.\",\n \"8.At 852, control selects the next UI in the breadcrumb and returns to 824.Search System In FIG.\",\n \"9, an example implementation of the search system 288 includes a search module 900.The search module 900 includes a query analysis module 904 that receives a query wrapper, which may take the form of a query string within a URL transmitted by the browser 228 of FIG.\",\n \"2.The query analysis module 904 analyzes the text query from the query wrapper.\",\n \"For example, the query analysis module 904 may tokenize the query text, filter the query text, and perform word stemming, synonymization, and stop word removal.\",\n \"The query analysis module 904 may also analyze additional data stored within the query wrapper.\",\n \"The query analysis module 904 provides the tokenized query to a set generation module 908.The set generation module 908 identifies a consideration set of application state records from a search data store 910 based on the query tokens.\",\n \"Application (equivalently, app) state records correspond to specific states of apps.\",\n \"In various implementations, the search data store 910 may also include app records.\",\n \"In various implementations, an app record may be stored as an app state record that simply has a predetermined value, such as null, for the specific state of the app.\",\n \"App state records in the search data store 910 may be generated by crawling and scraping apps according to the principles of the present disclosure.\",\n \"Some or all of the contents of the records of the search data store 910 may be indexed in inverted indices.\",\n \"In some implementations, the set generation module 908 uses the APACHE LUCENE software library by the Apache Software Foundation to identify records from the inverted indices.\",\n \"The set generation module 908 may search the inverted indices to identify records containing one or more query tokens.\",\n \"As the set generation module 908 identifies matching records, the set generation module 908 can include the unique ID of each identified record in the consideration set.\",\n \"For example, the set generation module 908 may compare query terms to an app state name and app attributes (such as a text description and user reviews) of an app state record.\",\n \"Further, in some implementations, the set generation module 908 may determine an initial score of the record with respect to the search query.\",\n \"The initial score may indicate how well the contents of the record matched the query.\",\n \"For example, the initial score may be a function of term frequency-inverse document frequency (TF-IDF) values of the respective query terms.\",\n \"A set processing module 912 receives unique IDs of app state records identified by the set generation module 908 and determines a result score for some or all of the IDs.\",\n \"A result score indicates the relevance of an app state with respect to the tokenized query and context parameters.\",\n \"In various implementations, a higher score indicates a greater perceived relevance.\",\n \"For example, other items in the query wrapper may act as context parameters.\",\n \"Geolocation data may limit the score of (or simply remove altogether) apps that are not pertinent to the location of the user device.\",\n \"A blacklist in the query wrapper may cause the set processing module 912 to remove app records and/or app state records from the consideration set that match the criteria in the blacklist, or to set their score to a null value, such as zero.\",\n \"The set processing module 912 may generate a result score based on one or more scoring features, such as record scoring features, query scoring features, and record-query scoring features.\",\n \"Example record scoring features may be based on measurements associated with the record, such as how often the record is retrieved during searches and how often links generated based on the record are selected by a user.\",\n \"Query scoring features may include, but are not limited to, the number of words in the search query, the popularity of the search query, and the expected frequency of the words in the search query.\",\n \"Record-query scoring features may include parameters that indicate how well the terms of the search query match the terms of the record indicated by the corresponding ID.\",\n \"The set processing module 912 may include one or more machine-learned models (such as a supervised learning model) configured to receive one or more scoring features.\",\n \"The one or more machine-learned models may generate result scores based on at least one of the record scoring features, the query scoring features, and the record-query scoring features.\",\n \"For example, the set processing module 912 may pair the search query with each app state ID and calculate a vector of features for each {query, ID} pair.\",\n \"The vector of features may include one or more record scoring features, one or more query scoring features, and one or more record-query scoring features.\",\n \"In some implementations, the set processing module 912 normalizes the scoring features in the feature vector.\",\n \"The set processing module 912 can set non-pertinent features to a null value or zero.\",\n \"The set processing module 912 may then input the feature vector for one of the app state IDs into a machine-learned regression model to calculate a result score for the ID.\",\n \"In some examples, the machine-learned regression model may include a set of decision trees (such as gradient-boosted decision trees).\",\n \"Additionally or alternatively, the machine-learned regression model may include a logistic probability formula.\",\n \"In some implementations, the machine-learned task can be framed as a semi-supervised learning task, where a minority of the training data is labeled with human-curated scores and the rest are used without human labels.\",\n \"The machine-learned model outputs a result score of the ID.\",\n \"The set processing module 912 can calculate result scores for each of the IDs that the set processing module 912 receives.\",\n \"The set processing module 912 associates the result scores with the respective IDs and outputs the most relevant scored IDs.\",\n \"A results generation module 924 may choose specific access mechanisms from the application records and app state records chosen by the set processing module 912.The results generation module 924 then prepares a results set to return to the user device.\",\n \"Although called “app state results” here, some of the access mechanisms may correspond to a default state (such as a home page) of an app—these may be a special case of an app state record or may be an app record.\",\n \"The results generation module 924 may select an access mechanism for an app state record based on whether the app is installed on the device.\",\n \"If the app is installed, an access mechanism that opens the app directly to the specified state is selected.\",\n \"Meanwhile, if the app is not installed, a selected access mechanism first downloads and installs the app, such as via a script, before opening the app to the specified state.\",\n \"Opening the app to the specified state may include a single command or data structure (such as an intent in the ANDROID operating system) that directly actuates the specified state.\",\n \"For other apps, a script or other sequence may be used to open the app to a certain state (such as a home, or default, state) and then navigate to the specified state.\",\n \"The results generation module 924 may generate or modify access mechanisms based on the operating system identity and version for the user device to which the results are being transmitted.\",\n \"For example, a script to download, install, open, and navigate to a designated state may be fully formed for a specific operating system by the results generation module 924.If the results generation module 924 determines that none of the native access mechanisms are likely to be compatible with the user device, the search module 900 may send a web access mechanism to the user device.\",\n \"If no web access mechanism is available, or would be incompatible with the user device for some reason (for example, if the web access mechanism relies on the JAVA programming language, which is not installed on the user device), the results generation module 924 may omit the result.\",\n \"Server-Side Control In FIG.\",\n \"10, operation of server-side components may be performed within a single device or may be performed across the developer portal 208, the offline analysis system 280, the data server 284, and the search

\"Such manipulation includes, for example, clicking, pressing, pinching, or swiping of the user interface.\",\n \"In addition to capturing a unique identifier for each UI element the operator

1116 is aware of states that are of interest to the operator, either explicitly (such as via the target state tracker 1112) or implicitly (such as via the guide tracker 1108).\",\n \"The link

the operator using the target state tracker 1112.If target states are not specified by the operator, the link extraction controller 1116 may assume that the final state reached when an operator is creating a guide is the target state.\",\n \"Alternatively, the link extraction controller 1116 may make the assumption that every state the operator navigated to should be a target state.\",\n \"A deduplication procedure may be used to detect when the operator has browsed in a loop, thus avoiding recording duplicative and/or non-shortest-path guides.\",\n \"Deduplication may be less necessary

types of textual input need to be entered.\",\n \"The types could be, for example, city names, cuisine names, etc.\",\n \"The link extraction controller 1116 then consults a knowledge base to get a list of possible values of such types (for cities, the list might include “Seattle,” “San Jose,” etc.)\",\n \"and then replay each one of these values into the textual input field.\",\n \"The link extraction controller 1116 may detect that a potential state of interest has already been reached by following a different breadcrumb.\",\n \"The link extraction controller 1116 may then select one of the breadcrumbs to associate with that state.\",\n \"For example, the breadcrumb having the fewest number of UI events may be selected.\",\n \"Alternatively, the breadcrumb having the fewest view changes may be selected, and total number of UI events may be used as a tiebreaker.\",\n \"To identify that a state has already been reached, the link extraction controller 1116 may store a fingerprint for each state along with the breadcrumb.\",\n \"The fingerprint may be a reduced representation of the components of a state.\",\n \"For example, a representation of visible objects may be created, such as by enumerating the objects in an XML data structure and then computing a mathematical hash (such as with MD5) of the data structure.\",\n \"The hash is then the fingerprint, and if

bookmarking so that when the state is encountered by a user, an activity corresponding to that state is bookmarked by sending an activity object to the operating system.\",\n \"Control continues at 1236, where the operator interaction leading to the present state is stored as a breadcrumb.\",\n \"If the breadcrumb was already stored at 1224 for the present state, an additional copy of the breadcrumb may be omitted from storage.\",\n \"Control continues at 1232.At 1232, control continues tracking operator interaction with the app.\",\n \"At 1240, control determines whether the operator has instructed the app to reset to a home state of the app.\",\n \"If so, control transfers to 1244; otherwise, control returns to 1212.Resetting the home state may be accomplished by a user interface element belonging to the simulator within which the app is operating.\",\n \"In other limitations, the app itself may have a mechanism for returning to the home state and this is recognized by 1240 as well.\",\n \"By resetting to the home state, the operator indicates that a new set of user interface events should be tracked to lead to another state of interest.\",\n \"At 1244, if the present state was not already marked as a deep link target, control stores the operator interaction leading to the present state as a breadcrumb and adds the present state to the list of target states.\",\n \"Control continues at 1248, where if the operator is done, control ends.\",\n \"Otherwise, control returns to 1208.Breadcrumb Extrapolation Referring to FIG.\",\n \"13, the operator may have established a series of breadcrumbs but not labeled any particular states as target states.\",\n \"For example, in some implementations, the operator may not be presented with an option to designate target states.\",\n \"However, operator-created breadcrumbs generally begin at a home state and end at a terminal (or, final) state.\",\n \"This final state may be assumed to be the state of interest for deep-linking.\",\n \"In other words, only terminal states are assumed to be target states.\",\n \"In other implementations, each state encountered along a breadcrumb is assumed to be a target state.\",\n \"For example, when an operator is creating breadcrumbs for a restaurant review application, the operator may create one breadcrumb by navigating from the home state to a state containing restaurant information and reviews.\",\n \"This would be assumed to be a desired target state, and the link extraction controller would attempt to find additional states that have similar data for scraping.\",\n \"Control begins at 1304, where a first breadcrumb from a list of operator-created breadcrumbs is selected.\",\n \"At 1308, control opens the app to a home state in an emulator.\",\n \"At 1312, control follows the selected breadcrumb, stopping in the state immediately before the final state.\",\n \"At 1316, control performs extrapolation to identify states similar to the final state.\",\n \"For example, control identifies UI widgets parallel to the UI widget that, when followed according to the selected breadcrumb, will reach the final state.\",\n \"At 1320, control adds the final state, as well as states reached from UI widgets identified as parallel, to a state list.\",\n \"Each of the added states is annotated with a breadcrumb based on the selected breadcrumb.\",\n \"The breadcrumb for the states other than the final state will diverge from the breadcrumb for the final state at the final UI event of each breadcrumb.\",\n \"At 1324, control determines whether additional breadcrumbs are present in the list of breadcrumbs.\",\n \"If so, control transfers to 1328; otherwise, control ends.\",\n \"At 1328, control selects the next breadcrumb from the list of breadcrumbs and returns to 1308.CONCLUSION The foregoing description is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses.\",\n

the present disclosure overcome one or more of the above-referenced and other deficiencies in conventional approaches to obtaining operational information in an electronic device.","In particular, various embodiments provide for the obtaining of debugging information through the inclusion of watermarks in rendered content.","Performance, state, configuration, debugging, and other information can be encoded into a watermark and placed in rendered content in such a way that the information is imperceptible to most users.","When a user reports a potential issue or problem, the user (or another source) can provide an image frame corresponding to the issue, which enables the watermark to be located and the data extracted.","A checksum or other value can be used to ensure that a complete and valid watermark was obtained.","The data extracted from the watermark can then be used to attempt to identify and/or diagnose the potential issue.","Various other functions and advantages are described and suggested below as may be provided in accordance with the various embodiments.","FIG.","1 illustrates an example situation 100 in which a page of content 104 is displayed on a computing device 102.Although a portable computing device is illustrated, it should be understood that any appropriate device can be used to present content in accordance with the various embodiments, as may include notebook computers, personal data assistants, e-book readers, cellular phones, video gaming consoles or controllers, smart televisions, set top boxes, a wearable computer (e.g., a smart watch or glasses), and portable media players, among others.","In this example, the content displayed includes image and text content, as may be rendered on the computing device 102 or by a remote rendering engine, among other such options.","The content can be Web content displayed through a browser application, content rendered by an application from a content provider or third party application provider, among other types of content.","In this example, the displayed content relates to furniture placed in a virtual room that enables a user to view collections of furniture in realistic environments.","There might be any of a number of issues with such a display or presentation of content, however.","In this example, the size of a lamp 112 displayed in the image is too large relative to the other content displayed.","Accordingly, a customer experiencing the issue might generate a notification to be sent to a provider of the content and/or application in order to report the alleged problem.","An entity receiving the notification may then want to be able to determine sufficient information to identify the type of problem or issue that was alleged to have been experienced on the device.","The entity might also attempt to determine contextual information in order for the entity to be able to recreate the situation and/or problem.","This can include information such as the content being displayed, the display settings, information about the device used to display the content, a time at which the content was displayed, a frame number if the problem occurred with a specific frame or set of frames, or other such information that may be known to one of ordinary skill in the art for debugging applications or content that would be apparent in light of the teachings and suggestions contained herein.","Problems can arise, however, when the entity attempting to diagnose the problem is unable to obtain the appropriate information.","For example, a rendering engine might have only limited capability with respect to the generating and/or outputting of metadata, state, or debugging data, among other such types of information.","If a rendering engine is not able to fully utilize a component such as an embedded view component or sandboxed renderer process, for example, retrieving debugging data might require implementing an additional interface or performing security exceptions, which might not be available or may not be implemented as needed, such as where a software author using cloud-based rendering chooses not to implement any auxiliary interfaces.","The choice to not implement such interfaces may be a valid choice due to the burden of implementing the interfaces as well as introducing security or other such issues.","In some embodiments a debugging process might not be allowed to send debugging data during normal rendering due bandwidth or security constraints, among other such issues.","It thus can be difficult for a developer to obtain debugging information such as program state information (i.e., the state of variables and calls made), timestamp information, subroutines executed, types or constants defined, frame information, processing data, sample data, failure occurrence record data, breakpoints met, and the like.","The types and amount of information can further depend upon the complexity of the content or application, the type of issue experienced, and other such factors.","Accordingly, approaches in accordance with various embodiments attempt to provide for the availability of debugging information by embedding the debugging information in the content (e.g., image, video, or audio content) presented using a computing device.","In particular, the debugging information can be inserted into an image frame as a watermark that is barely perceptible to the average user.","In this way, the debugging information can be available regardless of the type of application or device used to display the content, and can avoid various bandwidth, security, and other such concerns mentioned elsewhere herein.","A user experiencing a problem can provide a copy of the image with the notification, such as by capturing a screenshot or selecting an option that automatically captures and sends a copy of the image to a remote debugging service or other such location.","In other embodiments, a debugging tool can analyze the image on the client device in order to extract the debugging information and then provide the debugging information to the debugging service.","Various other approaches can be used as well as discussed and suggested elsewhere herein.","Various types of watermarks can be utilized in accordance with various embodiments.","A digital watermark can be embedded in noise-tolerant content, such as an image, audio, or video content.","Digital watermarks can be perceptible under certain conditions, such as under examination by a watermark extraction algorithm, but imperceptible under other conditions, such as upon viewing by a human user.","A watermark can be added to an image in some embodiments by adjusting the values of certain pixels of the image by amounts determined by a particular encoding engine.","The amount of adjusting should be such that the visible changes to the pixels are minimal, in order to reduce the impact and detectability by a user.","Further, the encoding can be performed using pixel locations that are likely to be less perceptible to a user.","In some embodiments, an encoding bit rate can be varied based on the underlying content and a rate of content change.","For example, when scrolling down quickly, a higher bit rate can be used to encode more information into each frame, as human eyes are unable to focus and differentiate the “artificial noise” from faster moving/changing content.","The visual complexity for choosing the amount of data to encode can be approximated by monitoring how much CPU time content rasterization requires and/or monitoring the kind of drawing instructions that were executed to generate a piece of content, such as a tile.","Bitrate change can be gradual or “modulated” near tile boundaries, to avoid regular-shaped changes in noise patterns, which could be more easily seen by humans.","As an example, FIG.","1B illustrates a subset of pixels corresponding to a region 108 of the image in FIG.","1A that is substantially represented by a single color value or pixel value.","If the encoding were to be placed using pixels in such a region, as illustrated in the encoded region 120 of FIG.","1C, the changes would be relatively noticeable to a user viewing the image content.","A lower bit rate can be used to encode information in these areas, but it might be desirable in at least some embodiments to use portions of the image, where available, that allow for the use of higher bit rates.","If the encoding were instead placed at locations such as the edges of letters or objects, which typically demonstrate some amount of blurring or antialiasing, the encoding may be less perceptible.","For example, FIG.","1D illustrates an example region 110 from the image of FIG.","1A that includes a portion of a letter represented in the image.","As illustrated, there are pixels of varying color around the edges of the letter.","If the encoding is positioned in such locations, such as near the edges of the letter where some amount of color gradation is expected by the user, the user may not be able to perceive the difference.","For example, FIG.","1E illustrates one such encoded region 140 where the encoding affects pixels near the edges of the letter.","While a side by side comparison would enable a user to discern the differences, a user just viewing FIG.","1E by itself would generally not perceive that any encoding had taken place.","While the encoding of the example of FIG.","1C might be perceptible to a user due in part to its placement, the placement in FIG.","1E can help to hide the encoding from a user.","This is not necessarily to attempt to hide the presence of the debugging information from the user, but can instead enable the information to be provided without negatively impacting the user experience.","For example, using the approach discussed with respect to FIG.","1E a user might not perceive any degradation or change in image quality through the inclusion of such information.","As mentioned, there can be various watermarking algorithms used to determine the encoding and placement of the debugging data in rendered image content.","These can include, for example, quantization type watermarking algorithms, spread-spectrum watermarking algorithms, or amplitude modulation watermarking algorithms, among others.","A watermarking process might utilize one or more different algorithms at different times, such as may depend at least in part upon a type of content, a type or amount of information to be embedded, a security level of the information, and the like.","It at least some embodiments the watermark encoded into an image can include a checksum, or multiple checksums, as it can be difficult in at least some embodiments to determine the presence of a valid watermark, as well as to ensure that the entire watermark has been located.","This is particularly true when the placement depends upon the location of objects represented in the content, and an image with a different portion, contrast, intensity, aspect ratio, resolution, or other such factor may result in an algorithm selecting different locations to place the encoding.","For multiple checksums, one might be included for each record/chunk as opposed to the entire watermark, where one or more of the records with checksums can be used to verify all the data was decoded.","Thus, if content is rendered with encoded information at determined locations using an algorithm, a screen shot from a user that includes additional or less information might result in that algorithm picking different places to look in the image.","Thus, a checksum, hash, watermark length identifier, or other such data included in the watermark can be useful in ensuring that a valid and complete watermark has been identified.","The data extracted can then be used to attempt to debug the problem, using any of a number of different debugging approaches as might be used for similar data obtained from conventional sources.","FIG.","2 illustrates an example environment 200 in which aspects of the various embodiments can be implemented.","In this example, content is to be rendered on a client device 202.The content can originate from a content provider network 208, for example, as may be received over a least one network 206, such as the Internet, an intranet, a local area network, a cellular network, or another appropriate wired and/or wireless network.","The content can be rendered using a rendering engine 204 on the client device and/or a rendering engine 214 in the resource provider environment 208, among other such options.","In this example, at least some of the content can be pulled from a content repository 216 and rendered by a rendering engine 214 before being provided to the client device 202 by at least one content server 212.A request for the content can be received to a network interface layer 210, which can include one or more interfaces such as application programming interfaces (APIs) for receiving requests, as well as various other network components such as routers, load balancers, and the like.","In at least some embodiments the content server 212 or another appropriate component can cause data to be written to at least one log 218, as may include information regarding the content served.","The content can be delivered across the at least one network 206 to the client device 202.As mentioned, at least some rendering can be performed by a rendering engine 204 on the client device.","For example, a rendering engine for a Web browser might take markup language content such as HTML and formatting information to render Web content to be displayed on the client device 202 that can be formatted to fit the display and the current zoom level, etc.","Various other components such as layout or placement engines can be used as well within the scope of the various embodiments.","These engines can render data once the data is received, or may begin rendering as the data is received, among other such options.","Further, a rendering engine might render only that portion of the content that will be visible, or may render some additional amount that can reduce the likelihood of chunking or delayed rendering in response to a navigation or zoom action, among other such possibilities.","As mentioned the client device can display the content, and if a user (or application or other source) detects a potential issue or problem with the content, software, or device, the user can cause the image information to be provided to the content provider network 208.As mentioned, this can be accomplished by a user capturing a screenshot of the content, taking a picture using a digital camera, or selecting an option in an executing application or console that causes image data to be captured, among other such options.","In some embodiments the image can be processed on the client device 202, while in other embodiments the image can be provided to the content provider network 208, wherein the image can be directed to a debugging engine 220 or other such system or service.","The debugging engine can have access (directly or indirectly) to a watermarking algorithm that can be used to analyze the image to attempt to locate and extract the watermark from the image.","The content of the watermark can be analyzed to verify the accuracy, validity, and completeness of the watermark, such as by analyzing a checksum, hash, or length identifier of the watermark data and ensuring that the content of the watermark is as expected.","If not, the image data can be re-analyzed using a different algorithm or different values for the same algorithm to attempt to determine the appropriate watermark.","In some instances there might be multiple watermarks, with one being embedded in the original content or otherwise provided, which might prevent a single watermark from being accurately detected.","In the event that a watermark cannot be properly identified, conventional approaches to locating debugging information can be used, among other such options.","It should be mentioned that, as discussed elsewhere herein, a debugging engine 224 can also be included on the client device 202 in order to embed watermark data to content rendered and/or displayed on the client.","In some embodiments a debugging engine 226 might be offered as a third party service and/or service outside the resource provider environment, whereby content from a provider can have debugging information added if the debugging service has access to the appropriate data to be included in the watermark.","If the watermark can be verified, the data included in the watermark can be analyzed and used to attempt to determine the source of the reported issue.","As mentioned, this can include attempting to recreate the situation using the information provided.","The watermark data, as discussed elsewhere herein, can include various types of data useful for debugging, as may include timestamp data, state data, frame data, configuration data, identifiers for external logs (additional logged information), serialized data structures that cause or are related to a failure, and the like.","This information can be compared, using a debugging engine 220 or other such component or service, to information stored in a log data store 218 or other such location, which might contain additional information for the image frame.","The amount of data that can be included in a watermark is limited, at least in keeping the perceptibility of the watermark low, such that additional information for the rendering might also be stored to a log data store.","By using identifier information (frame, timestamp, client, etc.)","from the watermark, the information from the watermark can be correlated with information in the log for purposes of obtaining additional information for debugging.","Similarly, the debugging engine can use the debugging information from the watermark to check for similar data in a debugging data store 222, or other such location, do determine whether similar issues previously arose for similar circumstances, which can help point to a solution if one was previously determined.","Once the appropriate information is obtained, any appropriate debugging process can be used to attempt to identify and rectify any potential issues, as would be apparent to one of ordinary skill in the art in light of the teachings and suggestions contained herein.","A rendering engine in some embodiments can employ an error-correction (ECC, parity bits), compression (such as Lempel-Ziv-Markov chain, arithmetic coding) and/or encryption scheme before watermarking, which can be separate from any such schemes in the watermarking algorithm itself.","This can enable the use of multiple different available watermarking libraries and/or algorithms, and can help to secure any private user data or prevent malicious third parties from feeding incorrect information.","An example rendering engine can provide a callback interface to the embedding application for adding additional debugging data, and another callback interface to the embedding application for notifying when it has added its changes to the output frame (i.e., finalized it), allowing a rendering engine to use application's output surface area.","The latter callback can contain a frame buffer texture handle (or equivalent) as a parameter.","When multiple layers of content are composited (i.e., flattened) into a final output image, a read-back phase may be used to retrieve the final frame texture and modify it directly.","In some embodiments, a translucent layer containing the watermark data can be composited (i.e., merged) to the output frame.","A watermarking algorithm might add actual noise to the image (not containing any data or containing dummy records) in some embodiments in order to make the output more pleasing to the human eye, such as when there's not enough data to cover the entire image area or tile.","The same debugging data can also be repeated multiple times, as discussed elsewhere herein, to increase the chances of the data surviving in the event that some portion of the image is lost or otherwise not provided.","In some embodiments there may be a queue of pending records, from which records can be encoded opportunistically to fill in any remaining unused watermark capacity after higher priority data has been encoded.","In some embodiments a rendering engine may keep collecting information (up to a limit, discarding lowest importance data) and keep a list of data records to be encoded, but only do the encoding when a screenshot function is activated, encoding as many as possible of the pending records into one frame.","When an application using a rendering engine encounters a problem, such as violating an internal check for correctness, the rendering engine may temporarily use an algorithm with a higher bit rate and/or higher complexity than for normal output frames, in order to encode more information or increase the probability of the encoded data surviving any future quality degradation, possibly causing skipping small number of output frames.","FIG.","3 illustrates an example process 300 for embedding debugging data in a watermark that can be utilized in accordance with various embodiments.","It should be understood that there can be additional, fewer, or alternative steps performed in similar or alternative orders, or in parallel, within the scope of the various embodiments unless otherwise stated.","In this example, content to be rendered for a frame can be obtained 302 from an appropriate source, such as from a content provider network or third party provider.","In some embodiments, the content can include webpage content (e.g., HTML) to be rendered that may include content from other providers, among other such content.","In addition, debugging data relevant to a frame (or set of frames) of content to be rendered can be determined.","This can include, for example, state data, frame number data, a time stamp, a client or customer identifier, and other such information.","Watermark data that includes the debugging data and some verification data can be generated 306 that is to be inserted into the frame after, or at the time, the frame is rendered.","As mentioned, the verification data can include a checksum, hash, or other mechanism that can be used to determine a completeness and validity of the watermark data.","The watermark data can also be encoded such that the data can be distributed across an image in such a way that the data can be extracted but is generally imperceptible to a user viewing the image.","The frame of content can then be rendered 308 and the watermark included.","The watermark can be included at the time of rendering, or can be added as a separate step after the initial rendering, among other such options.","As mentioned, portions of the watermark can be positioned near the edges of objects represented in the image that would typically demonstrate some amount of anti-aliasing, blending, blurring, or smoothing, such that a slight variation in pixel value will not be unexpected or even noticeable to a user.","The watermark in at least some embodiments is encoded into the bitmap written into the frame buffer for the content to be displayed.","The image can then be caused to be displayed 310, or otherwise presented, with the embedded watermark.","If the watermark is instead in audio data, for example, then the audio with the watermark can be provided to be played through one or more speakers, among other such options.","The capturing or saving of at least a portion of the rendered image is then enabled 312 in the event of an issue or potential problem, whereby the image can be provided to a debugging engine, service, or provider in order to enable that entity to extract the debugging information from the image, which can help to diagnose and/or re-create the identified issue.","FIG.","4 illustrates an example process 400 for extracting debugging data from a watermark that can be utilized in accordance with various embodiments.","In this example, an image (or image frame) is received 402 that correspond to a reported issue with the content, the rendering of the content, an application or device rendering the content, etc.","As mentioned, this image can be captured by a user using a screenshot function or digital camera, or can be captured by a console or application executing on the client device, among other such options.","The image can be processed 404 with a watermark extraction algorithm that can analyze some, or all, of the image to attempt to recognize the watermark.","Since this process will often be performed offline, the algorithm(s) can analyze the entire image using multiple passes with different parameters as needed to identify the watermark.","If a watermark cannot be located 406, a different approach can be attempted 408, such as to adjust one or more search parameters or utilize a different extraction algorithm.","Other data sources also can be used if a watermark cannot be located, such as those that would be used to obtain debugging data using conventional approaches.","Once located, the content of the watermark can be verified 410 using a checksum, hash, length value, or other parameter included in the watermark.","The data from the watermark can also be checked to ensure that the data corresponds to a valid watermark, includes appropriate debugging data, etc.","If the watermark is determined 412 to not be valid, another approach can be used as discussed above to attempt to locate a complete watermark or use other data sources, among other such options.","If the watermark is determined to be complete and valid, the debugging data or other appropriate information can be extracted 414 from the watermark and utilized 416 to attempt to determine contextual information for the reported issue.","As mentioned, this can include information such as a state of the device, a state of the content, a frame sequence number, a timestamp of the reported issue, performance data for the time of the issue, intentionally placed debugging data, a rendering time for the frame, a list of assumptions, a set of state flags, and other such information.","In some embodiments, a debugging tool can process a series of images to attempt to determine commonalities among images, analyze trends, or generate statistics, among other such features.","For example, statistics can be generated as to the frequency of types of watermarks, the frequency of invalid or incomplete watermarks detected, the percentage of images containing a certain flag or debugging data value, etc.","An advantage to processing several images using a debugging tool or service is that incomplete information may be able to be obtained by utilizing information obtained from other images.","For example, the display 500 of content in FIG.","5 illustrates the display of FIG.","1, except that here an embedded application or other source has caused other content to be displayed as an overlay 502 that obscures or occludes a portion of the displayed image.","In such a situation, at least a portion of the watermark embedded in the image may not be able to be determined from an image or screenshot.","If information from other images is available, which may also be sourced from content rendered for other clients, the information might be able to be completed or at least partially recovered in order to enable at least some of the debugging information to be determined for the corresponding situation.","Another advantage to embedding the debugging information in the image data is that a third party developer or content author can diagnose problems even if that party may not otherwise be able to obtain access to the appropriate data.","For example, a user posting a screenshot of the issue on a social networking site can be sufficient for an entity to analyze the screenshot and determine debugging information for the issue, without having to obtain the information from the user in some other way, such as through the submission of log files or the implementation of a listener interface to collect data, among other such options.","Such an approach also enables the party to debug the problem even if the identity of the poster is unknown or access is otherwise problematic.","Another advantage is that performance can be diagnosed and issues debugged using the data without the third party developer or author even being aware of the inclusion of the data in some embodiments, and where such modification is permitted and authorized.","In some embodiments, a web crawler can be used to “scrape” known discussion forums or support web sites to automatically identify any images containing watermarks, and retrieve production debugging data without end-users having to provide the images to the original software author.","Such an approach is also useful for developers of applications, or apps, that might be purchased through an application store provided by another provider.","The app developer thus might have no direct relationship with the customer.","The ability to embed debugging information in a watermark, however, enables the app developer to determine the debugging information as long as the appropriate watermarked portion is somehow available to the developer.","In some embodiments multiple instances of a watermark might be placed in an image frame, enabling the discovery of debugging data even if only a portion of the frame is visible.","In some embodiments, such as where there are multiple frames in a sequence, the watermark data might also be displayed over several frames such that a video clip would be necessary to obtain all the appropriate watermark data.","The watermark data can also be split over audio, video, and image encoding in some embodiments.","The watermark can include other information as well, such as state or content of a portion of a page that is not visible but currently rendered.","If an example screen includes around two million pixels and each pixel in this example can accept 32 bits of information, then there are around 8 megabytes of data available in a single image frame.","In such a frame, there can be tens of kilobytes of information added without becoming visible to the human eye using certain watermarking algorithms.","In some instances certain types of images might affect the quality of the encoding.","For example, an image that is saved to a JPEG format or compressed might lose some detail from the encoding that might make the watermark data unusable.","In some embodiments there might be different levels of encoding, some of which being more likely to survive such a change.","For example, a limited amount of high priority information might be encoded using a level or type of encoding that is more likely to survive a change, while lower priority information might be encoded using an approach that may be higher frequency and allow for a greater amount of information, but might be more likely to disappear in the event that the image is modified in some way.","FIG.","6 illustrates an example electronic user device 600 that can be used in accordance with various embodiments.","Although a portable computing device (e.g., an electronic book reader or tablet computer) is shown, it should be understood that any electronic device capable of receiving, determining, and/or processing input can be used in accordance with various embodiments discussed herein, where the devices can include, for example, desktop computers, notebook computers, personal data assistants, smart phones, video gaming consoles, television set top boxes, and portable media players.","In this example, the computing device 600 has a display screen 602 on the front side, which under normal operation will display information to a user facing the display screen (e.g., on the same side of the computing device as the display screen).","The computing device in this example includes at least one camera 604 or other imaging element for capturing still or video image information over at least a field of view of the at least one camera.","In some embodiments, the computing device might only contain one imaging element, and in other embodiments the computing device might contain several imaging elements.","Each image capture element may be, for example, a camera, a charge-coupled device (CCD), a motion detection sensor, or an infrared sensor, among many other possibilities.","If there are multiple image capture elements on the computing device, the image capture elements may be of different types.","In some embodiments, at least one imaging element can include at least one wide-angle optical element, such as a fish eye lens, that enables the camera to capture images over a wide range of angles, such as 180 degrees or more.","Further, each image capture element can comprise a digital still camera, configured to capture subsequent frames in rapid succession, or a video camera able to capture streaming video.","The example computing device 600 also includes at least one microphone 606 or other audio capture device capable of capturing audio data, such as words or commands spoken by a user of the device.","In this example, a microphone 606 is placed on the same side of the device as the display screen 602, such that the microphone will typically be better able to capture words spoken by a user of the device.","In at least some embodiments, a microphone can be a directional microphone that captures sound information from substantially directly in front of the microphone, and picks up only a limited amount of sound from other directions.","It should be understood that a microphone might be located on any appropriate surface of any region, face, or edge of the device in different embodiments, and that multiple microphones can be used for audio recording and filtering purposes, etc.","The example computing device 600 also includes at least one orientation sensor 608, such as a position and/or movement-determining element.","Such a sensor can include, for example, an accelerometer or gyroscope operable to detect an orientation and/or change in orientation of the computing device, as well as small movements of the device.","An orientation sensor also can include an electronic or digital compass, which can indicate a direction (e.g., north or south) in which the device is determined to be pointing (e.g., with respect to a primary axis or other such aspect).","An orientation sensor also can include or comprise a global positioning system (GPS) or similar positioning element operable to determine relative coordinates for a position of the computing device, as well as information about relatively large movements of the device.","Various embodiments can include one or more such elements in any appropriate combination.","As should be understood, the algorithms or mechanisms used for determining relative position, orientation, and/or movement can depend at least in part upon the selection of elements available to the device.","FIG.","7 illustrates a logical arrangement of a set of general components of an example computing device 700 such as the device 600 described with respect to FIG.","6.In this example, the device includes a processor 702 for executing instructions that can be stored in a memory device or element 704.As would be apparent to one of ordinary skill in the art, the device can include many types of memory, data storage, or non-transitory computer-readable storage media, such as a first data storage for program instructions for execution by the processor 702, a separate storage for images or data, a removable memory for sharing information with other devices, etc.","The device typically will include some type of display element 706, such as a touch screen or liquid crystal display (LCD), although devices such as portable media players might convey information via other means, such as through audio speakers.","As discussed, the device in many embodiments will include at least one image capture element 708 such as a camera or infrared sensor that is able to image projected images or other objects in the vicinity of the device.","Methods for capturing images or video using a camera element with a computing device are well known in the art and will not be discussed herein in detail.","It should be understood that image capture can be performed using a single image, multiple images, periodic imaging, continuous image capturing, image streaming, etc.","Further, a device can include the ability to start and/or stop image capture, such as when receiving a command from a user, application, or other device.","The example device similarly includes at least one audio capture component, such as a mono or stereo microphone or microphone array, operable to capture audio information from at least one primary direction.","A microphone can be a uni-or omni-directional microphone as known for such devices.","In some embodiments, the computing device 700 of FIG.","7 can include one or more communication elements (not shown), such as a Wi-Fi, Bluetooth, RF, wired, or wireless communication system.","The device in many embodiments can communicate with a network, such as the Internet, and may be able to communicate with other such devices.","In some embodiments the device can include at least one additional input component 712 able to receive conventional input from a user.","This conventional input can include, for example, a push button, touch pad, touch screen, wheel, joystick, keyboard, mouse, keypad, or any other such device or element whereby a user can input a command to the device.","In some embodiments, however, such a device might not include any buttons at all, and might be controlled only through a combination of visual and audio commands, such that a user can control the device without having to be in contact with the device.","The device 700 also can include at least one orientation or motion sensor or component 710.As discussed, such a sensor can include an accelerometer or gyroscope operable to detect an orientation and/or change in orientation, or an electronic or digital compass, which can indicate a direction in which the device is determined to be facing.","The mechanism(s) also (or alternatively) can include or comprise a global positioning system (GPS) or similar positioning element operable to determine relative coordinates for a position of the computing device, as well as information about relatively large movements of the device.","The device can include other elements as well, such as may enable location determinations through triangulation or another such approach.","These mechanisms can communicate with the processor 702, whereby the device can perform any of a number of actions described or suggested herein.","As an example, a computing device such as that described with respect to FIG.","6 can capture and/or track various information for a user over time.","This information can include any appropriate information, such as location, actions (e.g., sending a message or creating a document), user behavior (e.g., how often a user performs a task, the amount of time a user spends on a task, the ways in which a user navigates through an interface, etc.","), user preferences (e.g., how a user likes to receive information), open applications, submitted requests, received calls, and the like.","As discussed above, the information can be stored in such a way that the information is linked or otherwise associated whereby a user can access the information using any appropriate dimension or group of dimensions.","As discussed, different approaches can be implemented in various environments in accordance with the described embodiments.","For example, FIG.","8 illustrates an example of an environment 800 for implementing aspects in accordance with various embodiments.","As will be appreciated, although a Web-based environment is used for purposes of explanation, different environments may be used, as appropriate, to implement various embodiments.","The system includes an electronic client device 802, which can include any appropriate device operable to send and receive requests, messages or information over an appropriate network 804 and convey information back to a user of the device.","Examples of such client devices include personal computers, cell phones, handheld messaging devices, laptop computers, set-top boxes, personal data assistants, electronic book readers and the like.","The network can include any appropriate network, including an intranet, the Internet, a cellular network, a local area network or any other such network or combination thereof.","Components used for such a system can depend at least in part upon the type of network and/or environment selected.","Protocols and components for communicating via such a network are well known and will not be discussed herein in detail.","Communication over the network can be enabled via wired or wireless connections and combinations thereof.","In this example, the network includes the Internet, as the environment includes a Web server 806 for receiving requests and serving content in response thereto, although for other networks an alternative device serving a similar purpose could be used, as would be apparent to one of ordinary skill in the art.","The illustrative environment includes at least one application server 808 and a data store 810.It should be understood that there can be several application servers, layers or other elements, processes or components, which may be chained or otherwise configured, which can interact to perform tasks such as obtaining data from an appropriate data store.","As used herein the term “data store” refers to any device or combination of devices capable of storing, accessing and retrieving data, which may include any combination and number of data servers, databases, data storage devices and data storage media, in any standard, distributed or clustered environment.","The application server can include any appropriate hardware and software for integrating with the data store as needed to execute aspects of one or more applications for the client device and handling a majority of the data access and business logic for an application.","The application server provides access control services in cooperation with the data store and is able to generate content such as text, graphics, audio and/or video to be transferred to the user, which may be served to the user by the Web server in the form of HTML, XML or another appropriate structured language in this example.","The handling of all requests and responses, as well as the delivery of content between the client device 802 and the application server 808, can be handled by the Web server 806.It should be understood that the Web and application servers are not required and are merely example components, as structured code discussed herein can be executed on any appropriate device or host machine as discussed elsewhere herein.","The data store 810 can include several separate data tables, databases or other data storage mechanisms and media for storing data relating to a particular aspect.","For example, the data store illustrated includes mechanisms for storing production data 812 and user information 816, which can be used to serve content for the production side.","The data store also is shown to include a mechanism for storing log or session data 814.It should be understood that there can be many other aspects that may need to be stored in the data store, such as page image information and access rights information, which can be stored in any of the above listed mechanisms as appropriate or in additional mechanisms in the data store 810.The data store 810 is operable, through logic associated therewith, to receive instructions from the application server 808 and obtain, update or otherwise process data in response thereto.","In one example, a user might submit a search request for a certain type of element.","In this case, the data store might access the user information to verify the identity of the user and can access the catalog detail information to obtain information about elements of that type.","The information can then be returned to the user, such as in a results listing on a Web page that the user is able to view via a browser on the user device 802.Information for a particular element of interest can be viewed in a dedicated page or window of the browser.","Each server typically will include an operating system that provides executable program instructions for the general administration and operation of that server and typically will include computer-readable medium storing instructions that, when executed by a processor of the server, allow the server to perform its intended functions.","Suitable implementations for the operating system and general functionality of the servers are known or commercially available and are readily implemented by persons having ordinary skill in the art, particularly in light of the disclosure herein.","The environment in one embodiment is a distributed computing environment utilizing several computer systems and

information can be encoded into a watermark and placed in rendered content in such a way that the information is imperceptible to most users.\",\n \"When a user reports a potential issue or problem, the user (or another source) can provide an image frame corresponding to the issue, which enables the watermark to be located and the data extracted.\",\n \"A checksum or other value can be used to ensure that a complete and valid watermark was obtained.\",\n \"The data extracted from the watermark can then be used to attempt to identify and/or diagnose the potential issue.\",\n \"Various other functions and advantages are described and suggested below as may be provided in accordance with the various embodiments.\",\n \"FIG.\",\n \"1 illustrates an example situation 100 in which a page of content 104 is displayed on a computing device 102.Although a portable computing device is illustrated, it should be understood that any appropriate device can be used to present content in accordance with the various embodiments, as may include notebook computers, personal data assistants, e-book readers, cellular phones, video gaming consoles or controllers, smart televisions, set top boxes, a wearable computer (e.g., a smart watch or glasses), and portable media players, among others.\",\n \"In this example, the content displayed includes image and text content, as may be rendered on the computing device 102 or by a remote rendering engine, among other such options.\",\n \"The content can be Web content displayed through a browser application, content rendered by an application from a content provider or third party application provider, among other types of content.\",\n \"In this example, the displayed content relates to furniture placed in a virtual room that enables a user to view collections of furniture in realistic environments.\",\n \"There might be any of a number of issues with such a display or presentation of content, however.\",\n \"In this example, the size of a lamp 112 displayed in the image is too large relative to the other content displayed.\",\n \"Accordingly, a customer experiencing the issue might generate a notification to be sent to a provider of the content and/or application in order to report the alleged problem.\",\n \"An entity receiving the notification may then want to be able to determine sufficient information to identify the type of problem or issue that was alleged to have been experienced on the device.\",\n \"The entity might also attempt to determine contextual information in order for the entity to be able to recreate the situation and/or problem.\",\n \"This can include information such as the content being displayed, the display settings, information about the device used to display the content, a time at which the content was displayed, a frame number if the problem occurred with a specific frame or set of frames, or other such information that may be known to one of ordinary skill in the art for debugging applications or content that would be apparent in light of the teachings and suggestions contained herein.\",\n \"Problems can arise, however, when the entity attempting to diagnose the problem is unable to obtain the appropriate information.\",\n \"For example, a rendering engine might have only limited capability with respect to the generating and/or outputting of metadata, state, or debugging data, among other such types of information.\",\n \"If a rendering engine is not able to fully utilize a component such as an embedded view component or sandboxed renderer process, for example, retrieving debugging data might require implementing an additional interface or performing security exceptions, which might not be available or may not be implemented as needed, such as where a software author using cloud-based rendering chooses not to implement any auxiliary interfaces.\",\n \"The choice to not implement such interfaces may be a valid choice due to the burden of implementing the interfaces as well as introducing security or other such issues.\",\n \"In some embodiments a debugging process might not be allowed to send debugging data during normal rendering due bandwidth or security constraints, among other such issues.\",\n \"It thus can be difficult for a developer to obtain debugging information such as program state information (i.e., the state of variables and calls made), timestamp information, subroutines executed, types or constants defined, frame information, processing data, sample data, failure occurrence record data, breakpoints met, and the like.\",\n \"The types and amount of information can further depend upon the complexity of the content or application, the type of issue experienced, and other such factors.\",\n \"Accordingly, approaches in accordance with various embodiments attempt to provide for the availability of debugging information by embedding the debugging information in the content (e.g., image, video, or audio content) presented using a computing device.\",\n \"In particular, the debugging information can be inserted into an image frame as a watermark that is barely perceptible to the average user.\",\n \"In this way, the debugging information can be available regardless of the type of application or device used to display the content, and can avoid various bandwidth, security, and other such concerns mentioned elsewhere herein.\",\n \"A user experiencing a problem can provide a copy of the image with the notification, such as by capturing a screenshot or selecting an option that automatically captures and sends a copy of the image to a remote debugging service or other such location.\",\n \"In other embodiments, a debugging tool can analyze the image on the client device in order to extract the debugging information and then provide the debugging information to the debugging service.\",\n \"Various other approaches can be used as well as discussed and suggested elsewhere herein.\",\n \"Various types of watermarks can be utilized in accordance with various embodiments.\",\n \"A digital watermark can be embedded in noise-tolerant content, such as an image, audio, or video content.\",\n \"Digital watermarks can be perceptible under certain conditions, such as under examination by a watermark extraction algorithm, but imperceptible under other conditions, such as upon viewing by a human user.\",\n \"A watermark can be added to an image in some embodiments by adjusting the values of certain pixels of the image by amounts determined by a particular encoding engine.\",\n \"The amount of adjusting should be such that the visible changes to the pixels are minimal, in order to reduce the impact and detectability by a user.\",\n \"Further, the encoding can be performed using pixel locations that are likely to be less perceptible to a user.\",\n \"In some embodiments, an encoding bit rate can be varied based on the underlying content and a rate of content change.\",\n \"For example, when scrolling down quickly, a higher bit rate can be used to encode more information into each frame, as human eyes are unable to focus and differentiate the “artificial noise” from faster moving/changing content.\",\n \"The visual complexity for choosing the amount of data to encode can be approximated by monitoring how much CPU time content rasterization requires and/or monitoring the kind of drawing instructions that were executed to generate a piece of content, such as a tile.\",\n \"Bitrate change can be gradual or “modulated” near tile boundaries, to avoid regular-shaped changes in noise patterns, which could be more easily seen by humans.\",\n \"As an example, FIG.\",\n \"1B illustrates a subset of pixels corresponding to a region 108 of the image in FIG.\",\n \"1A that is substantially represented by a single color value or pixel value.\",\n \"If the encoding were to be placed using pixels in such a region, as illustrated in the encoded region 120 of FIG.\",\n \"1C, the changes would be relatively noticeable to a user viewing the image content.\",\n \"A lower bit rate can be used to encode information in these areas, but it might be desirable in at least some embodiments to use portions of the image, where available, that allow for the use of higher bit rates.\",\n \"If the encoding were instead placed at locations such as the edges of letters or objects, which typically demonstrate some amount of blurring or antialiasing, the encoding may be less perceptible.\",\n \"For example, FIG.\",\n \"1D illustrates an example region 110 from the image of FIG.\",\n \"1A that includes a portion of a letter represented in the image.\",\n \"As illustrated, there are pixels of varying color around the edges of the letter.\",\n \"If the encoding is positioned in such locations, such as near the edges of the letter where some amount of color gradation is expected by the user, the user may not be able to perceive the difference.\",\n \"For example, FIG.\",\n \"1E illustrates one such encoded region 140 where the encoding affects pixels near the edges of the letter.\",\n \"While a side by side comparison would enable a user to discern the differences, a user just viewing FIG.\",\n \"1E by itself would generally not perceive that any encoding had taken place.\",\n \"While the encoding of the example of FIG.\",\n \"1C might be perceptible to a user due in part to its placement, the placement in FIG.\",\n \"1E can help to hide the encoding from a user.\",\n \"This is not necessarily to attempt to hide the presence of the debugging information from the user, but can instead enable the information to be provided without negatively impacting the user experience.\",\n \"For example, using the approach discussed with respect to FIG.\",\n \"1E a user might not perceive any degradation or change in image quality through the inclusion of such information.\",\n \"As mentioned, there can be various watermarking algorithms used to determine the encoding and placement of the debugging data in rendered image content.\",\n \"These can include, for example, quantization type watermarking algorithms, spread-spectrum watermarking algorithms, or amplitude modulation watermarking algorithms, among others.\",\n \"A watermarking process might utilize one or more different algorithms at different times, such as may depend at least in part upon a type of content, a type or amount of information to be embedded, a security level of the information, and the like.\",\n \"It at least some embodiments the watermark encoded into an image can include a checksum, or multiple checksums, as it can be difficult in at least some embodiments to determine the presence of a valid watermark, as well as to ensure that the entire watermark has been located.\",\n \"This is particularly true when the placement depends upon the location of objects represented in the content, and an image with a different portion, contrast, intensity, aspect ratio, resolution, or other such factor may result in an algorithm selecting different locations to place the encoding.\",\n \"For multiple checksums, one might be included for each record/chunk as opposed to the entire watermark, where one or more of the records with checksums can be used to verify all the data was decoded.\",\n \"Thus, if content is rendered with encoded information at determined locations using an algorithm, a screen shot from a user that includes additional or less information might result in that algorithm picking different places to look in the image.\",\n \"Thus, a checksum, hash, watermark length identifier, or other such data included in the watermark can be useful in ensuring that a valid and complete watermark has been identified.\",\n \"The data extracted can then be used to attempt to debug the problem, using any of a number of different debugging approaches as might be used for similar data obtained from conventional sources.\",\n \"FIG.\",\n \"2 illustrates an example environment 200 in which aspects of the various embodiments can be implemented.\",\n \"In this example, content is to be rendered on a client device 202.The content can originate from a content provider network 208, for example, as may be received over a least one network 206, such as the Internet, an intranet, a local area network, a cellular network, or another appropriate wired and/or wireless network.\",\n \"The content can be rendered using a rendering engine 204 on the client device and/or a rendering engine 214 in the resource provider environment 208, among other such options.\",\n \"In this example, at least some of the content can be pulled from a content repository 216 and rendered by a rendering engine 214 before being provided to the client device 202 by at least one content server 212.A request for the content can be received to a network interface layer 210, which can include one or more interfaces such as application programming interfaces (APIs) for receiving requests, as well as various other network components such as routers, load balancers, and the like.\",\n \"In at least some embodiments the content server 212 or another appropriate component can cause data to be written to at least one log 218, as may include information regarding the content served.\",\n \"The content can be delivered across the at least one network 206 to the client device 202.As mentioned, at least some rendering can be performed by a rendering engine 204 on the client device.\",\n \"For example, a rendering engine for a Web browser might take markup language content such as HTML and formatting information to render Web content to be displayed on the client device 202 that can be formatted to fit the display and the current zoom level, etc.\",\n \"Various other components such as layout or placement engines can be used as well within the scope of the various embodiments.\",\n \"These engines can render data once the data is received, or may begin rendering as the data is received, among other such options.\",\n \"Further, a rendering engine might render only that portion of the content that will be visible, or may render some additional amount that can reduce the likelihood of chunking or delayed rendering in response to a navigation or zoom action, among other such possibilities.\",\n \"As mentioned the client device can display the content, and if a user (or application or other source) detects a potential issue or problem with the content, software, or device, the user can cause the image information to be provided to the content provider network 208.As mentioned, this can be accomplished by a user capturing a screenshot of the content, taking a picture using a digital camera, or selecting an option in an executing application or console that causes image data to be captured, among other such options.\",\n \"In some embodiments the image can be processed on the client device 202, while in other embodiments the image can be provided to the content provider network 208, wherein the image can be directed to a debugging engine 220 or other such system or service.\",\n \"The debugging engine can have access (directly or indirectly) to a watermarking algorithm that can be used to analyze the image to attempt to locate and extract the watermark from the image.\",\n \"The content of the watermark can be analyzed to verify the accuracy, validity, and completeness of the watermark, such as by analyzing a checksum, hash, or length identifier of the watermark data and ensuring that the content of the watermark is as expected.\",\n \"If not, the image data can be re-analyzed using a different algorithm or different values for the same algorithm to attempt to determine the appropriate watermark.\",\n \"In some instances there might be multiple watermarks, with one being embedded in the original content or otherwise provided, which might prevent a single watermark from being accurately detected.\",\n \"In the event that a watermark cannot be properly identified, conventional approaches to locating debugging information can be used, among other such options.\",\n \"It should be mentioned that, as discussed elsewhere herein, a debugging engine 224 can also be included on the client device 202 in order to embed watermark data to content rendered and/or displayed on the client.\",\n \"In some embodiments a debugging engine 226 might be offered as a third party service and/or service outside the resource provider environment, whereby content from a provider can have debugging information added if the debugging service has access to the appropriate data to be included in the watermark.\",\n \"If the watermark can be verified, the data included in the watermark can be analyzed and used to attempt to determine the source of the reported issue.\",\n \"As mentioned, this can include attempting to recreate the situation using the information provided.\",\n \"The watermark data, as discussed elsewhere herein, can include various types of data useful for debugging, as may include timestamp data, state data, frame data, configuration data, identifiers for external logs (additional logged information), serialized data structures that cause or are related to a failure, and the like.\",\n \"This information can be compared, using a debugging engine 220 or other such component or service, to information stored in a log data store 218 or other such location, which might contain additional information for the image frame.\",\n \"The amount of data that can be included in a watermark is limited, at least in keeping the perceptibility of the watermark low, such that additional information for the rendering might also be stored to a log data store.\",\n \"By using identifier information (frame, timestamp, client, etc.)\",\n \"from the watermark, the information from the watermark can be correlated with information in the log for purposes of obtaining additional information for debugging.\",\n \"Similarly, the debugging engine can use the debugging information from the watermark to check for similar data in a debugging data store 222, or other such location, do determine whether similar issues previously arose for similar circumstances, which can help point to a solution if one was previously determined.\",\n \"Once the appropriate information is obtained, any appropriate debugging process can be used to attempt to identify and rectify any potential issues, as would be apparent to one of ordinary skill in the art in light of the teachings and suggestions contained herein.\",\n \"A rendering engine in some embodiments can employ an error-correction (ECC, parity bits), compression (such as Lempel-Ziv-Markov chain, arithmetic coding) and/or encryption scheme before watermarking, which can be separate from any such schemes in the watermarking algorithm itself.\",\n \"This can enable the use of multiple different available watermarking libraries and/or algorithms, and can help to secure any private user data or prevent malicious third parties from feeding incorrect information.\",\n \"An example rendering engine can provide a callback interface to the embedding application for adding additional debugging data, and another callback interface to the embedding application for notifying when it has added its changes to the output frame (i.e., finalized it), allowing a rendering engine to use application's output surface area.\",\n \"The latter callback can contain a frame buffer texture handle (or equivalent) as a parameter.\",\n \"When multiple layers of content are composited (i.e., flattened) into a final output image, a read-back phase may be used to retrieve the final frame texture and modify it directly.\",\n \"In some embodiments, a translucent layer containing the watermark data can be composited (i.e., merged) to the output frame.\",\n \"A watermarking algorithm might add actual noise to the image (not containing any data or containing dummy records) in some embodiments in order to make the output more pleasing to the human eye, such as when there's not enough data to cover the entire image area or tile.\",\n \"The same debugging data can also be repeated multiple times, as discussed elsewhere herein, to increase the chances of the data surviving in the event that some portion of the image is lost or otherwise not provided.\",\n \"In some embodiments there may be a queue of pending records, from which records can be encoded opportunistically to fill in any remaining unused watermark capacity after higher priority data has been encoded.\",\n \"In some embodiments a rendering engine may keep collecting information (up to a limit, discarding lowest importance data) and keep a list of data records to be encoded, but only do the encoding when a screenshot function is activated, encoding as many as possible of the pending records into one frame.\",\n \"When an application using a rendering engine encounters a problem, such as violating an internal check for correctness, the rendering engine may temporarily use an algorithm with a higher bit rate and/or higher complexity than for normal output frames, in order to encode more information or increase the probability of the encoded data surviving any future quality degradation, possibly causing skipping small number of output frames.\",\n \"FIG.\",\n \"3 illustrates an example process 300 for embedding debugging data in a watermark that can be utilized in accordance with various embodiments.\",\n \"It should be understood that there can be additional, fewer, or alternative steps performed in similar or alternative orders, or in parallel, within the scope of the various embodiments unless otherwise stated.\",\n \"In this example, content to be rendered for a frame can be obtained 302 from an appropriate source, such as from a content provider network or third party provider.\",\n \"In some embodiments, the content can include webpage content (e.g., HTML) to be rendered that may include content from other providers, among other such content.\",\n \"In addition, debugging data relevant to a frame (or set of frames) of content to be rendered can be determined.\",\n \"This can include, for example, state data, frame number data, a time stamp, a client or customer identifier, and other such information.\",\n \"Watermark data that includes the debugging data and some verification data can be generated 306 that is to be inserted into the frame after, or at the time, the frame is rendered.\",\n \"As mentioned, the verification data can include a checksum, hash, or other mechanism that can be used to determine a completeness and validity of the watermark data.\",\n \"The watermark data can also be encoded such that the data can be distributed across an image in such a way that the data can be extracted but is generally imperceptible to a user viewing the image.\",\n \"The frame of content can then be rendered 308 and the watermark included.\",\n \"The watermark can be included at the time of rendering, or can be added as a separate step after the initial rendering, among other such options.\",\n \"As mentioned, portions of the watermark can be positioned near the edges of objects represented in the image that would typically demonstrate some amount of anti-aliasing, blending, blurring, or smoothing, such that a slight variation in pixel value will not be unexpected or even noticeable to a user.\",\n \"The watermark in at least some embodiments is encoded into the bitmap written into the frame buffer for the content to be displayed.\",\n \"The image can then be caused to be displayed 310, or otherwise presented, with the embedded watermark.\",\n \"If the watermark is instead in audio data, for example, then the audio with the watermark can be provided to be played through one or more speakers, among other such options.\",\n \"The capturing or saving of at least a portion of the rendered image is then enabled 312 in the event of an issue or potential problem, whereby the image can be provided to a debugging engine, service, or provider in order to enable that entity to extract the debugging information from the image, which can help to diagnose and/or re-create the identified issue.\",\n \"FIG.\",\n \"4 illustrates an example process 400 for extracting debugging data from a watermark that can be utilized in accordance with various embodiments.\",\n \"In this example, an image (or image frame) is received 402 that correspond to a reported issue with the content, the rendering of the content, an application or device rendering the content, etc.\",\n \"As mentioned, this image can be captured by a user using a screenshot function or digital camera, or can be captured by a console or application executing on the client device, among other such options.\",\n \"The image can be processed 404 with a watermark extraction algorithm that can analyze some, or all, of the image to attempt to recognize the watermark.\",\n \"Since this process will often be performed offline, the algorithm(s) can analyze the entire image using multiple passes with different parameters as needed to identify the watermark.\",\n \"If a watermark cannot be located 406, a different approach can be attempted 408, such as to adjust one or more search parameters or utilize a different extraction algorithm.\",\n \"Other data sources also can be used if a watermark cannot be located, such as those that would be used to obtain debugging data using conventional approaches.\",\n \"Once located, the content of the watermark can be verified 410 using a checksum, hash, length value, or other parameter included in the watermark.\",\n \"The data from the watermark can also be checked to ensure that the data corresponds to a valid watermark, includes appropriate debugging data, etc.\",\n \"If the watermark is determined 412 to not be valid, another approach can be used as discussed above to attempt to locate a complete watermark or use other data sources, among other such options.\",\n \"If the watermark is determined to be complete and valid, the debugging data or other appropriate information can be extracted 414 from the watermark and utilized 416 to attempt to determine contextual information for the reported issue.\",\n \"As mentioned, this can include information such as a state of the device, a state of the content, a frame sequence number, a timestamp of the reported issue, performance data for the time of the issue, intentionally placed debugging data, a rendering time for the frame, a list of assumptions, a set of state flags, and other such information.\",\n \"In some embodiments, a debugging tool can process a series of images to attempt to determine commonalities among images, analyze trends, or generate statistics, among other such features.\",\n \"For example, statistics can be generated as to the frequency of types of watermarks, the frequency of invalid or incomplete watermarks detected, the percentage of images containing a certain flag or debugging data value, etc.\",\n \"An advantage to processing several images using a debugging tool or service is that incomplete information may be able to be obtained by utilizing information obtained from other images.\",\n \"For example, the display 500 of content in FIG.\",\n \"5 illustrates the display of FIG.\",\n \"1, except that here an embedded application or other source has caused other content to be displayed as an overlay 502 that obscures or occludes a portion of the displayed image.\",\n \"In such a situation, at least a portion of the watermark embedded in the image may not be able to be determined from an image or screenshot.\",\n \"If information from other images is available, which may also be sourced from content rendered for other clients, the information might be able to be completed or at least partially recovered in order to enable at least some of the debugging information to be determined for the corresponding situation.\",\n \"Another advantage to embedding the debugging information in the image data is that a third party developer or content author can diagnose problems even if that party may not otherwise be able to obtain access to the appropriate data.\",\n \"For example, a user posting a screenshot of the issue on a social networking site can be sufficient for an entity to analyze the screenshot and determine debugging information for the issue, without having to obtain the information from the user in some other way, such as through the submission of log files or the implementation of a listener interface to collect data, among other such options.\",\n \"Such an approach also enables the party to debug the problem even if the identity of the poster is unknown or access is otherwise problematic.\",\n \"Another advantage is that performance can be diagnosed and issues debugged using the data without the third party developer or author even being aware of the inclusion of the data in some embodiments, and where such modification is permitted and authorized.\",\n \"In some embodiments, a web crawler can be used to “scrape” known discussion forums or support web sites to automatically identify any images containing watermarks, and retrieve production debugging data without end-users having to provide the images to the original software author.\",\n \"Such an approach is also useful for developers of applications, or apps, that might be purchased through an application store provided by another provider.\",\n \"The app developer thus might have no direct relationship with the customer.\",\n \"The ability to embed debugging information in a watermark, however, enables the app developer to determine the debugging information as long as the appropriate watermarked portion is somehow available to the developer.\",\n \"In some embodiments multiple instances of a watermark might be placed in an image frame, enabling the discovery of debugging data even if only a portion of the frame is visible.\",\n \"In some embodiments, such as where there are multiple frames in a sequence, the watermark data might also be displayed over several frames such that a video clip would be necessary to obtain all the appropriate watermark data.\",\n \"The watermark data can also be split over audio, video, and image encoding in some embodiments.\",\n \"The watermark can include other information as well, such as state or content of a portion of a page that is not visible but currently rendered.\",\n \"If an example screen includes around two million pixels and each pixel in this example can accept 32 bits of information, then there are around 8 megabytes of data available in a single image frame.\",\n \"In such a frame, there can be tens of kilobytes of information added without becoming visible to the human eye using certain watermarking algorithms.\",\n \"In some instances certain types of images might affect the quality of the encoding.\",\n \"For example, an image that is saved to a JPEG format or compressed might lose some detail from the encoding that might make the watermark data unusable.\",\n \"In some embodiments there might be different levels of encoding, some of which being more likely to survive such a change.\",\n \"For example, a limited amount of high priority information might be encoded using a level or type of encoding that is more likely to survive a change, while lower priority information might be encoded using an approach that may be higher frequency and allow for a greater amount of information, but might be more likely to disappear in the event that the image is modified in some way.\",\n \"FIG.\",\n \"6 illustrates an example electronic user device 600 that can be used in accordance with various embodiments.\",\n \"Although a portable computing device (e.g., an electronic book reader or tablet computer) is shown, it should be understood that any electronic device capable of receiving, determining, and/or processing input can be used in accordance with various embodiments discussed herein, where the devices can include, for example, desktop computers, notebook computers, personal data assistants, smart phones, video gaming consoles, television set top boxes, and portable media players.\",\n \"In this example, the computing device 600 has a display screen 602 on the front side, which under normal operation will display information to a user facing the display screen (e.g., on the same side of the computing device as the display

least one camera.\",\n \"In some embodiments, the computing device might only contain one imaging element, and in other embodiments the computing device might contain several imaging elements.\",\n \"Each image capture element may be, for example, a camera, a charge-coupled device (CCD), a motion detection sensor, or an infrared sensor, among many other possibilities.\",\n \"If there are multiple image capture elements on the computing device, the image capture elements may be of different types.\",\n \"In some embodiments, at least one imaging element can include at least one wide-angle optical element, such as a fish eye lens, that enables the camera to capture images over a wide range of angles, such as 180 degrees or more.\",\n \"Further, each image capture element can comprise a digital still camera, configured to capture subsequent frames in rapid succession, or a video camera able to capture streaming video.\",\n \"The example computing device 600 also includes at least one microphone 606 or other audio capture device capable of capturing audio data, such as words or commands spoken by a user of the device.\",\n \"In this example, a microphone 606 is placed

microphone can be a directional microphone that captures sound information from substantially directly in front of the microphone, and picks up only a limited amount of sound from other directions.\",\n \"It should be understood that a microphone might be located on any appropriate surface of any region, face, or edge of the device in different embodiments, and that multiple microphones can be used for audio recording and filtering purposes, etc.\",\n \"The example computing device 600 also includes at least one orientation sensor 608, such as a position and/or

well as small movements of the device.\",\n \"An orientation sensor also can include an electronic or digital compass, which can indicate a direction (e.g., north or south) in which the device is determined to be pointing (e.g., with respect to a primary axis or other such aspect).\",\n \"An orientation sensor also can include or comprise a global positioning system (GPS) or similar positioning element operable to determine relative coordinates for a position of the computing device, as well as information about relatively large movements of the device.\",\n \"Various embodiments can include one or more such elements in any appropriate combination.\",\n \"As should be understood, the algorithms or mechanisms used for determining relative position, orientation, and/or movement

118 can be held closed using locking flanges 117, 119 (FIG.","4).","In one implementation, the enclosure housing 110 is molded from a plastic material.","In one implementation, the enclosure housing 110 is molded from a plastic material.","In another implementation, the enclosure housing 110 is molded from a metal material.","In some implementations, the enclosure housing 110 defines one or more cable ports 101 (FIG.","1) at which cables 180, 190 may enter and exit the interior of the enclosure housing 110.In certain implementations, the cable ports 101 are disposed at the bottom wall 112 of the enclosure housing 110.In other implementations, however, the cable ports 101 may be disposed elsewhere on the enclosure housing 110, such as at the top wall 111, the rear wall 115, or one of the side walls 113, 114.In some implementations, the enclosure housing 110 is configured to receive one or more cable port modules 150 at the cable ports 101 (e.g., see FIGS.","3 and 4).","For example, the cable ports 101 may define openings 155 (FIG.","4) in one or more walls 111-115 of the enclosure housing 110 at which the cable port modules 150 may be received.","Each cable port module 150 receives one or more cables 180, 190.In some implementations, a first cable port module 150 may receive one or more service cables and a second cable port module 150 may receive one or more subscriber cables.","In other implementations, the same cable port module 150 may receive both service cables and subscriber cables.","In still other implementations, the enclosure housing 110 may receive an even greater number of cable port modules 150, each of which may receive service cables and/or subscriber cables.","In certain implementations, a variety of cable port modules 150 may be configured to fit at the same opening 155, thereby enabling a user to select which of the cable port modules 150 to mount at the opening 155.In certain implementations, the cable port modules 150 may be removably mounted to the enclosure housing at the openings 155, thereby enabling a user to switch which cable port modules 150 are mounted at any particular enclosure housing 110.Two example implementations of cable port modules 150, 150′ are shown in FIGS.","3 and 4.Each of the cable port modules 150, 150′ includes a port panel 151 configured to be mounted at an opening 155 defined in an enclosure housing 110.For example, the port panel 151 may define one or more openings 152 through which fasteners (e.g., screws, bolts, etc.)","may extend to secure the port panel 151 to one of the walls 111-115 of the enclosure housing 110.One or more grommets extend through the port panel 151.Each grommet enables one or more cables 180, 190 or fibers to enter the enclosure housing 110 while inhibiting the ingress of environmental contaminants, such as water, dirt, and rodents.","A first example cable port module 150 includes a first type of grommet 153 and a second type of grommet 154.The second type of grommet 154 is larger than the first type of grommet 153.In the example shown, a cable 180 to be dispensed extends through the smaller grommet 153.A second example cable port module 150′ includes only the second type of grommet 154 extending through the port panel 151.Other implementations may include still other types of cable port modules, each having its own configuration of grommets.","Referring to FIGS.","4-15, the mounting plates 121 of the modular plate assemblies 120 are adapted and configured to be mounted to the rear wall 115 of the enclosure housing 110.In some implementations, the rear wall 115 defines one or more openings through which fasteners may extend to secure a mounting plate 121 to the rear wall 115.In other implementations, the rear wall 115 may include one or more pegs over which the mounting plate 121 may be pressed.","In other implementations, one or more panel fastening structures can be attached, secured, or mounted to the rear wall 115.In still other implementations, the rear wall 115 may include one or more pems 104 that are pressed into the rear wall 115 (see FIG.","4).","The pems 104 are sized and configured to be inserted through openings 122 defined in the mounting plate 121.The pems 104 define threaded passages that are configured to receive fasteners that secure the mounting plate 121 to the rear wall 115, or can be exterior threaded shanks.","In accordance with some aspects, the mounting plates 121 of the modular plate assemblies 120 extend over a majority of the area of the rear wall 115.In some implementations, a mounting plate 121 has a rectangular shape (e.g., see FIG.","4).","In other implementations, a mounting plate 121 may define one or more cutouts 129 or otherwise have a non-rectangular shape (e.g., see FIGS.","9-12).","In accordance with other aspects, the mounting plates 121 of the modular plate assemblies 120 may extend over only a portion of the area of the rear wall 115.For example, some implementations, of the mounting plates 121 may be configured to extend over about half of the area of the rear wall 115 (e.g., see FIGS.","11-14).","FIGS.","4-7 illustrate a first implementation of a modular plate assembly 120 that includes a cable spool arrangement 130 (FIG.","6) that is rotationally mounted to the modular plate assembly 120.As shown in FIG.","5, the cable spool arrangement 130 includes a first storage area 102, a second storage area 104, and a termination region 108.In some implementations, the termination region 108 is spaced from the second storage area 104, which is spaced from the first storage area 102.In certain implementations, the termination region 108 is spaced forwardly of the second storage region 104, which is spaced forwardly of the first storage region 102 (e.g., see FIG.","4).","In certain implementations, the second storage area 104 forms part of a protected fiber management region 106 at which optical fibers can be separated out from optical cables.","At least a first fiber cable (e.g., distribution cable) 180 and at least a second cable (e.g., subscriber cable) 190 enter the housing 110 through cable ports 101.Fibers 192 of the second fiber cable 190 are routed to the termination region 108.The first fiber cable 180 is routed to the first storage area 102 of the cable spool arrangement 130.From the first storage area 102, the first fiber cable 180 is routed to the second storage area 104.The first fiber cable 180 is broken out into individual optical fibers 182 at the protected fiber management region 106.The fibers 182 are routed to the termination region 108 at which the optical fibers 184 are connected to optical fibers 192 of the second fiber cable 190.The fiber optic enclosure 100 provides an enclosure from which lengths of a cable (e.g., a distribution cable) 180 can be dispensed following the mounting of the fiber optic enclosure 100 to a mounting location.","The distribution cable 180 is dispensed from the fiber optic enclosure 100 by pulling on an end (e.g., a connectorized end) 185 of the cable 180 (see FIGS.","4 and 7).","As the distribution cable 180 is dispensed, the cable spool arrangement 130 rotates about an axis relative to the stationary mounting plate 121 of the fiber optic enclosure 100.In the event that there is a residual length of distribution cable 180 that is not dispensed during the cable payout, the fiber optic enclosure 100 can store this residual length.","As shown in FIG.","6, the cable spool mounting assembly 120 includes a mounting plate 121 and a cable spool arrangement 130.The mounting plate 121 includes a first side 124 and an opposite second side 123.The mounting plate 121 is adapted for stationary mounting to the rear wall 115 of the housing enclosure.","In certain implementations, the second side 123 of the mounting plate 121 is configured to be mounted to an interior surface of the rear wall 115 so that the mounting plate 121 is disposed within the interior of the housing enclosure 110.For example, in certain implementations, the mounting plate 121 defines one or more fastener openings 122 that are disposed to align with fastener openings provided on the rear wall 115 of the housing enclosure 110.Certain types of mounting plates 121 extend along substantially the entire rear wall 115 of the enclosure housing 110.The cable spool arrangement 130 includes a drum 131 extending between first and second support flanges 132, 133 to form a first cable spool 134.The first cable spool 134 defines the first storage region 102 (FIG.","5).","In some implementations, the cable spool arrangement 130 also includes a termination region 108 (FIG.","5).","In certain implementations, a protected fiber management region 106 (FIG.","5) is defined between the first storage region 102 and the termination region 108.For example, in certain implementations, in FIG.","6, the cable spool arrangement 130 includes a stand-off mounting assembly 140, at which the termination region 108 (FIG.","5) is disposed as will be described in more detail herein.","The protected fiber management region 106 (FIG.","5) is defined between the stand-off mounting assembly 140 and one of the first cable spool 134 (e.g., see FIG.","4).","In certain implementations, the drum portion 131 of the first cable spool 134 is generally cylindrical in shape.","The drum portion 131 includes a first end portion that couples to the first support flange 132 and an oppositely disposed second end portion that couples to the second support flange 133.The support flanges 132, 133, which are generally parallel to each other, are configured to rotate with the drum 131.An outer surface of the drum 131 and inner surfaces of the support flanges 132, 133 define the first storage region 102 (FIG.","5) within which optical fibers or cables (e.g., distribution cable 180) may be coiled.","The drum portion 131 has a sufficient diameter to provide bend radius protection to optical fibers wound around the fiber spool 134.The drum portion 131 defines a central bore that extends through the drum portion 131.In the subject embodiment, the central bore is adapted to receive a spindle 129 (FIG.","6).","In certain implementations, the spindle 129 extends through the bore in the drum 131 and secures to the second side 123 of the mounting plate 121.For example, in certain implementations, the mounting plate 121 defines openings 125 at which the spindle 129 is fastened to the mounting plate 121.The first cable spool 134 is configured to rotate about the spindle 129 relative to the mounting plate 121.The support flanges 132, 133 are sized and shaped to retain the optical fibers wound around the drum 131 in the first storage region 102.In some implementations, the support flanges 132, 133 are generally circular.","In certain implementations, the support flanges 132, 133 have a sufficient diameter to cover a majority of a surface area of the mounting plate 121.In other implementations, however, one or both of the support flanges 132, 133 may have a smaller diameter.","In some implementations, the cable spool arrangement 130 is configured to be releasably locked in a rotationally fixed position relative to the mounting plate 121.For example, in certain implementations, the mounting plate 121 includes a forwardly extending flange 126 that is configured to extend past the support flanges 132, 133 of the drum 131 to interact with the front of the cable spool arrangement 130 (see FIG.","6).","The forwardly extending flange 126 defines an opening 127.The second flange 133 of the cable spool 134 defines an opening 136 that is disposed to align with the opening 127 of the forwardly extending flange 126 when the cable spool arrangement 130 is disposed in one rotational position.","In certain implementations, the opening 136 is defined in a tab 135 that extends outwardly from the generally annular circumference of the second support flange 133.A fastener 128 may be inserted through the openings 136, 127 to lock the cable spool arrangement 130 in the rotationally fixed position.","In some implementations, the second support flange 133 of the cable spool 134 defines an aperture 139 through which optical fibers or cables (e.g., distribution cable 180) may pass between the first storage area 102 and the front of the cable spool 134.In certain implementations, the cables pass through aperture 139 from the first storage region 102 to the protected fiber management region 106.For example, in certain implementations, the aperture 139 is located directly adjacent to the protected fiber management region 106 and allows cables from inside the first storage region 102 of the spool to be routed from the drum surface 131 to the protected storage region 106.The protected fiber management region 106 (FIG.","5) provides a mounting location for a fan out arrangement.","The fan out arrangement includes one or more fan outs 138 disposed between the back side of the stand-off 140 and the front side of the cable spool 134 (see FIG.","4).","For example, the fan outs 138 may be disposed on the front side of the second support flange 133 of the cable spool 134.Accordingly, the fan outs 138 rotate with the cable spool 134.The cable 180 wrapped around the supplemental spool region 104 can be routed to one of the fan outs 138 where individual optical fiber are broken out to form individual fiber optic pigtails 182.The pigtails 182 have ends connectorized by fiber optic connectors that are inserted into the fiber optic adapters 147 at the termination field 108 (see FIG.","4).","Fiber optic connectors corresponding to fibers 192 of subscriber cables 190 also may be inserted into the adapters 147 to provide optical connections between the subscriber cables 190 and the cables 180 routed from the first cable spool 134.The protected fiber management region 106 also can include bend radius protectors 137 attached to the front spool flange 133 (FIG.","6).","The bend radius protector 137 can form a supplemental spooling region 104 where cables routed from drum 131 through aperture 139 can be wrapped/spooled to provide cable storage and cable management.","The pigtails 182 also may be wrapped/spooled around the bend radius limiters 137.In some implementations, the supplemental spooling region 104 provides strain relief to the cables (e.g., distribution cables) 180.Axial loads applied to the outside end 185 of the cables 180 will be transferred through the cable 180 to the wrapped portions of the cable 180.However, the axial loads will not be transferred to the connectorized ends of the pigtails 182.Accordingly, pulling on the first cable end 185 will not detach the connectorized pigtails 182 from the adapters 147 at the termination region 108.Still referring to FIGS.","4-7, a stand-off mount element 140 may be coupled to the front of the first cable spool 134.For example, the stand-off mount element 140 may be secured to the second support flange 133 of the first cable spool 134 so that the stand-off mount element 140 unitarily rotates with the first cable spool 134.The stand-off mount element 140 provides a front plate 141 where optical components (e.g., fiber optic adapters, splitters, splice trays, spools, bend radius protector, etc.)","can be mounted.","For example, fiber optic adapters 147 may form a termination region 108 on the front plate 141.Cable management structures (e.g., bend radius limiters, spools, etc.)","148 also may be provided on the stand-off plate 141.In the example shown, two opposing bend radius limiters 148 form a fiber spool on the stand-off plate 141.In certain implementations, one or more legs 142 extend rearwardly from the stand-off plate 141 of the stand-off mount element 140.Each leg 142 defines an opening 143 configured to receive a peg 145 or fastener to secure the feet 143 to the front support flange 133 of the cable spool 134.In the example shown, the stand-off mount element 140 includes four legs 142.In other implementations, however, the stand-off mount element 140 may include greater or fewer legs 142.In still other implementations, the legs 142 may be unitary with the cable spool 134 and secure to the stand-off plate 141.The stand-off plate 141 is forwardly offset from the front side of the spool flange 133, thereby forming the protected fiber management region 106 between the front side of the first cable spool 134 and back side of the stand-off mount element 140 (e.g., see FIG.","4).","The separated fibers 184 in the protected fiber management region 106 are routed around the bend radius limiters 137 or other management structures on the front of the cable spool 134 to the stand-off mount element 140.In the example shown, the separated fibers 184 have connectorized ends that plug into first ports of termination adapters 147 disposed at the stand-off plate 141.Components disposed on the stand-off mount element 140 are spaced forwardly of the cable spool 134.Accordingly, the fiber optic adapters 147 are disposed on a different layer or plane than the fan outs 138, which are disposed on a different layer or plane than the first cable spool 134.In certain implementations, the fan outs 138 are disposed on the same layer or plane as the bend radius limiters 137.The spacing between the cable spool layer and the stand-off layer enhances slack storage of optical fibers routed through the protected fiber management region 106.In some implementations, the spacing between the cable spool layer and the stand-off layer inhibits over-bending of the fibers when routed between the fan out arrangements 138 and the fiber optic adapters 147.In certain implementations, the termination adapters 147 are included in one or more termination modules 146.In certain implementations, the adapter modules 146 are sliding adapter modules.","Similar sliding adapter modules have been described in commonly owned U.S. Pat.","Nos.","5,497,444; 5,717,810; 6,591,051; and 7,416,349, the disclosures of which are hereby incorporated by reference.","In the example shown, the stand-off mount element 140 includes six sliding adapter modules 146, each holding four fiber optic adapters 147.In other implementations, the stand-off mount element 140 may include greater or fewer sliding adapter modules 146 holding greater or fewer termination adapters 147.In certain implementations, sufficient slack length of the separated fibers 182 is left between the fan out arrangement 138 and the adapters 147 to accommodate the sliding movement of the sliding adapter modules 146.In some implementations, the cable spool arrangement 130 may be precabled at the factory or manufacturing center with one or more optical fibers or cables 180.For example, one or more multi-fiber cables 180 may be wound around the storage area 102 of the cable spool 134.In certain implementations, the multi-fiber cables 180 may be precabled to pass through the aperture 139 to the fan out arrangement 138 disposed in the protected fiber management region 106 (e.g., see FIGS.","4 and 7).","The fan out arrangement 138 separates the cables 180 into pigtails 182.In certain implementations, the fan out arrangement 138 also upjackets the fibers 182.In other implementations, however, the cable spool arrangement 130 may be cabled with the one or more multi-fiber cables 180 after the enclosure housing 110 is deployed.","The precabled cable spool mounting assembly 120 is mounted within the enclosure housing 110.For example, the mounting plate 121 is secured to a rear wall 115 of the enclosure housing 110.When the mounting assembly 120 is installed in the enclosure housing 110, the second ends of the multi-fiber cables 180 may be routed through one of the cable ports so that the second ends are disposed outside of the enclosure housing 110.In some implementations, the second ends of the one or more precabled multi-fiber cables 180 may be terminated at one or more multi-fiber connectors 185.In other implementations, the second end of a precabled multi-fiber cable 180 is separated into two or more connectorized optical fibers (jacketed or unjacketed).","In still other implementations, the second ends of the multi-fiber cables 180 are configured to be spliced to one or more optical fiber cables.","A user may pull on the second ends to dispense the stored length of cable 180 from the cable spool arrangement 130.For example, a user may pull a second end of a cable 180 to a fiber distribution hub, drop terminal, or other network connection.","Because the adapters 147 rotate in unison with the cable spool arrangement 130, the second end of each multi-fiber cable 180 may be paid out without interfering with the cabling of the first ends of the multi-fiber cable 180.When the second ends 185 of the one or more multi-fiber cables 180 are each connected to the network, the fastener 128 may be inserted through aligned openings 135, 128 to secure the cable spool arrangement 130 in a fixed rotational position relative to the mounting plate 121.When the cable spool arrangement 130 is secured in a rotationally fixed position, additional optical fiber cables may be routed into the enclosure housing 110 to secure to second ports of the termination adapters 147.For example, the additional optical fiber cables may be routed into the enclosure through one or more cable ports defined in the enclosure housing 110.The termination adapters 147 are configured to align and optically couple connectors terminating the additional optical cables with the connectorized ends of the multi-fiber cable 180 plugged into the first ports of the adapters 147.FIG.","8 illustrates a second example modular plate assembly 220 implemented as a second example cable spool mounting assembly 120 for mounting within the enclosure housing 110.The second cable spool mounting assembly 220 includes a rectangular mounting plate 221 that extends over a majority of the rear wall 115.A cable spool arrangement 241 is disposed on the mounting plate 221 and is configured to rotate relative to the mounting plate 221 (e.g., about a spindle).","Since the mounting plate 221 is configured to remain stationary on the rear wall 115, the cable spool arrangement 241 is configured to rotate relative to the enclosure housing 110.The cable spool arrangement 241 defines a storage area including a drum about which optical fibers or cables (e.g.","of a multi-fiber distribution cable 180) may be coiled.","The drum has a sufficient diameter to provide bend radius protection to optical fibers wound around the fiber spool arrangement 241.Rotating the cable spool arrangement 241 dispenses or retracts the optical fibers or cables wound around the drum.","In some implementations, the cable spool arrangement 241 may be locked in a rotational orientation relative to the mounting plate 221.In certain implementations, one or more splice trays 242 are disposed on the cable spool arrangement 241.Each splice tray 242 is configured to optically couple together two or more optical fibers.","For example, each splice tray 242 may optically couple together at least one optical fiber of the distribution cable 180 and at least one optical fiber of a subscriber cable 190 (FIG.","1).","Certain types of splice tray 242 may be pivoted between open and closed positions to provide access to the splices contained therein.","In certain implementations, the splice trays 242 are stacked upon each other so that a bottom of the stack extends over the cable spool arrangement 241 and a top of the stack faces the open front 116 of the enclosure housing 110.One or more fiber management structures may be disposed on the cable spool arrangement 241.For example, in certain implementations, one or more bend radius limiters 243 are disposed on a front of the cable spool arrangement 241.In the example shown, four bend radius limiters are disposed at a top, bottom, and sides of the cable spool arrangement 241.The cable spool arrangement 241 also defines one or more channels 244 through which optical fibers or cables can pass between the storage area of the cable spool arrangement 241 and the splice trays 242.In the example shown, the cable spool arrangement 241 defines four openings 244 spaced between the bend radius limiters 243.In some implementations, the second cable spool mounting assembly 220 may be precabled at the factory or manufacturing center with one or more distribution cables 180.The one or more distribution cables 180 may be wound around the drum in the storage area of the second cable spool arrangement 241.In certain implementations, the first end of each distribution cable fiber may be routed through one of the openings 244 in the cable spool arrangement 241, around one or more of the bend radius limiters 243, and into one of the splice trays 242 disposed at a front of the cable spool arrangement 241 (e.g., see FIG.","8).","The precabled second cable spool mounting assembly 220 is mounted within the enclosure housing 110 to deploy the one or more distribution cables 180.For example, the mounting plate 221 is secured to the rear wall 115 of the enclosure housing 110 as described above.","The second ends 185 of the distribution cables 180 may be routed out of the housing 110 through one of the cable port modules 101 so that the second ends 185 are disposed outside of the enclosure housing 110 (e.g., see FIG.","8).","Additional optical fiber cables (e.g., subscriber cables 190 of FIG.","1) may be routed into the enclosure housing 110 (e.g., through the same or other port modules 101).","Unconnectorized ends of the subscriber cable fibers may be optically coupled to the first ends of the service cable fibers at the splice trays 242.For example, each subscriber cable fiber may be routed from the respective cable port module 101 to the respective splice tray 242 (e.g., either directly or after being wound around some of the bend radius limiters 243 of the second cable spool mounting assembly 220.FIGS.","9 and 10 illustrate a third example modular plate assembly 120 implemented as a termination panel mounting assembly 320.The termination panel mounting assembly 320 includes a mounting plate 321 that is sized to extend over a majority of the rear wall 115 of the enclosure housing 110.In particular, the mounting plate 321 has a height that extends over a majority of a height of the rear wall 115 and the mounting plate 321 has a width that extends over a majority of a width of the rear wall 115.The mounting plate 321 defines one or more apertures 322 or pems that facilitate connection to the rear wall 115.Certain types of mounting plates 321 define one or more cutouts 329.In the example shown in FIG.","9, the mounting plate 321 defines a cutout 329 at an upper, right corner of the mounting plate 321, thereby resulting in an L-shaped mounting panel 321.In other implementations, the mounting plate 321 may have other configurations.","A termination plate 351 is coupled to the mounting plate 321.In some implementations, the termination plate 351 is a bent portion of the mounting plate 321.In other implementations, the termination plate 351 is a separate piece that attaches to the mounting plate 321 (e.g., via snap-fit connection, latches, fasteners, etc.).","In the example shown, the termination plate 351 extends vertically with a first side facing the first side wall 113 and a second side facing he second side wall 114 of the enclosure housing 110.In other implementations, the termination plate 351 has a first side that faces the rear wall 115 and a second side that faces the open front 116 of the enclosure housing 110.One or more termination adapters 352 are disposed on the termination plate 351.Each termination adapter 352 has a first port and a second port.","In the example shown, the first port faces the first side wall 113 and the second port faces the second side wall 114 of the enclosure housing 110.In other implementations, the adapter ports may face the rear wall 115 and open front 116 of the enclosure housing 110.In still other implementations, the adapters 352 and the termination plate 351 may be oriented at any desired angle relative to the mounting plate 321.In certain implementations, adapter dust caps 353 may be provided at the adapter ports.","In certain implementations, one or more cable management structures may be provided on the termination plate 351 or mounting plate 321.In the example shown, four bend radius limiters 354 are disposed on a front of the mounting plate 321.The bend radius limiters 354 are configured to form two fiber spools.","In certain implementations, the bend radius limiters 354 form a first fiber spool located between the termination plate 351 and the first side wall 113 of the housing 110 and a second fiber spool located between the termination plate 351 and the second side wall 114 of the housing 110.In certain implementations, the bend radius limiters 354 are located substantially below the termination plate 351.In other implementations, the same or other types of cable management structures may be disposed in different configurations.","During deployment of the termination panel mounting assembly 350, one or more optical fiber cables (e.g., distribution cables 180) may be routed into the enclosure housing 110 (e.g., through one or more port modules 101).","Connectorized ends of the distribution cables may be secured to the first ports of the termination adapters 352.Additional optical fiber cables (e.g., subscriber cables 190) also may be routed into the enclosure housing 110 (e.g., through the same or other port modules 101).","Connectorized ends of the subscriber cables may be secured to the second ports of the termination adapters 352, which align and optically couple together the connectorized ends of the subscriber cables with the connectorized ends of the service cables.","In

Reference will now be made in detail to the exemplary aspects of the present disclosure that are illustrated in the accompanying drawings.\",\n \"Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like structure.\",\n \"FIG.\",\n \"1 is a schematic diagram of an example fiber optic enclosure 100.The fiber optic enclosure 100 includes a housing, generally designated 110, at which telecommunications cables (e.g., optical and/or electrical cables) can be optically coupled and/or stored.\",\n \"One or more modular plate assemblies 120 may be mounted within the interior of the enclosure housing 110.Each modular plate assembly 120 includes a mounting plate 121 that is configured to mount to the enclosure housing 110 in a stationary configuration.\",\n \"Each modular plate assembly 120 includes a coupling arrangement 170 at which one or more optical fibers 182 of at least a first fiber cable 180 are optically coupled to optical fibers 192 of at least a second fiber cable 190.The fiber cables 180, 190 enter the enclosure housing 110 through cable ports 101.In use, the enclosure housing 110 is deployed by securing the enclosure housing 110 to a mounting location (e.g., a wall, a pole, etc.).\",\n \"In some implementations, the enclosure housing 110 has brackets disposed on the top and bottom walls 111, 112.In other implementations, the enclosure housing 110 may have brackets disposed on other walls to secure the enclosure housing 110 to the mounting location.\",\n \"In still other implementations, the enclosure housing 110 is adapted to be otherwise secured to a mounting location.\",\n \"FIGS.\",\n \"2-4 illustrate one example enclosure housing 110 having a top wall 111, a bottom wall 112 (FIG.\",\n \"3), a first side wall 113, a second side wall 114 (FIG.\",\n \"4), and a rear wall 115 (FIG.\",\n \"4) defining an interior.\",\n \"The enclosure housing 110 also defines an open front 116 that provides access to the interior of the enclosure housing 110 (see FIG.\",\n \"4).\",\n \"At least one cover 118 is coupled to the enclosure housing 110 to selectively close the open front 116 of the enclosure housing 110.The cover 118 is pivotally coupled to the enclosure housing 110 using one or more hinges 103 disposed on one of the side walls 113, 114 (see FIG.\",\n \"4).\",\n \"The hinge 103 allows the cover 118 to selectively pivot between a closed position (shown in FIG.\",\n \"2) and an open position (shown in FIG.\",\n \"4).\",\n \"The cover 118 can be held closed using locking flanges 117, 119 (FIG.\",\n \"4).\",\n \"In one implementation, the enclosure housing 110 is molded from a plastic material.\",\n \"In one implementation, the enclosure housing 110 is molded from a plastic material.\",\n \"In another implementation, the enclosure housing 110 is molded from a metal material.\",\n \"In some implementations, the enclosure housing 110 defines one or more cable ports 101 (FIG.\",\n \"1) at which cables 180, 190 may enter and exit the interior of the enclosure housing 110.In certain implementations, the cable ports 101 are disposed at the bottom wall 112 of the enclosure housing 110.In other implementations, however, the cable ports 101 may be disposed elsewhere on the enclosure housing 110, such as at the top wall 111, the rear wall 115, or one of the side walls 113, 114.In some implementations, the enclosure housing 110 is configured to receive one or more cable port modules 150 at the cable ports 101 (e.g., see FIGS.\",\n \"3 and 4).\",\n \"For example, the cable ports 101 may define openings 155 (FIG.\",\n \"4) in one or more walls 111-115 of the enclosure housing 110 at which the cable port modules 150 may be received.\",\n \"Each cable port module 150 receives one or more cables 180, 190.In some implementations, a first cable port module 150 may receive one or more service cables and a second cable port module 150 may receive one or more subscriber cables.\",\n \"In other implementations, the same cable port module 150 may receive both service cables and subscriber cables.\",\n \"In still other implementations, the enclosure housing 110 may receive an even greater number of cable port modules 150, each of which may receive service cables and/or subscriber cables.\",\n \"In certain implementations, a variety of cable port modules 150 may be configured to fit at the same opening 155, thereby enabling a user to select which of the cable port modules 150 to mount at the opening 155.In certain implementations, the cable port modules 150 may be removably mounted to the enclosure housing at the openings 155, thereby enabling a user to switch which cable port modules 150 are mounted at any particular enclosure housing 110.Two example implementations of cable port modules 150, 150′ are shown in FIGS.\",\n \"3 and 4.Each of the cable port modules 150, 150′ includes a port panel 151 configured to be mounted at an opening 155 defined in an enclosure housing 110.For example, the port panel 151 may define one or more openings 152 through which fasteners (e.g., screws, bolts, etc.)\",\n \"may extend to secure the port panel 151 to one of the walls 111-115 of the enclosure housing 110.One or more grommets extend through the port panel 151.Each grommet enables one or more cables 180, 190 or fibers to enter the enclosure housing 110 while inhibiting the ingress of environmental contaminants, such as water, dirt, and rodents.\",\n \"A first example cable port module 150 includes a first type of grommet 153 and a second type of grommet 154.The second type of grommet 154 is larger than the first type of grommet 153.In the example shown, a cable 180 to be dispensed extends through the smaller grommet 153.A second example cable port module 150′ includes only the second type of grommet 154 extending through the port panel 151.Other implementations may include still other types of cable port modules, each having its own configuration of grommets.\",\n \"Referring to FIGS.\",\n \"4-15, the mounting plates 121 of the modular plate assemblies 120 are adapted and configured to be mounted to the rear wall 115 of the enclosure housing 110.In some implementations, the rear wall 115 defines one or more openings through which fasteners may extend to secure a mounting plate 121 to the rear wall 115.In other implementations, the rear wall 115 may include one or more pegs over which the mounting plate 121 may be pressed.\",\n \"In other implementations, one or more panel fastening structures can be attached, secured, or mounted to the rear wall 115.In still other implementations, the rear wall 115 may include one or more pems 104 that are pressed into the rear wall 115 (see FIG.\",\n \"4).\",\n \"The pems 104 are sized and configured to be inserted through openings 122 defined in the mounting plate 121.The pems 104 define threaded passages that are configured to receive fasteners that secure the mounting plate 121 to the rear wall 115, or can be exterior threaded shanks.\",\n \"In accordance with some aspects, the mounting plates 121 of the modular plate assemblies 120 extend over a majority of the area of the rear wall 115.In some implementations, a mounting plate 121 has a rectangular shape (e.g., see FIG.\",\n \"4).\",\n \"In other implementations, a mounting plate 121 may define one or more cutouts 129 or otherwise have a non-rectangular shape (e.g., see FIGS.\",\n \"9-12).\",\n \"In accordance with other aspects, the mounting plates 121 of the modular plate assemblies 120 may extend over only a portion of the area of the rear wall 115.For example, some implementations, of the mounting plates 121 may be configured to extend over about half of the area of the rear wall 115 (e.g., see FIGS.\",\n \"11-14).\",\n \"FIGS.\",\n \"4-7 illustrate a first implementation of a modular plate assembly 120 that includes a cable spool arrangement 130 (FIG.\",\n \"6) that is rotationally mounted to the modular plate assembly 120.As shown in FIG.\",\n \"5, the cable spool arrangement 130 includes a first storage area 102, a second storage area 104, and a termination region 108.In some implementations, the termination region 108 is spaced from the second storage area 104, which is spaced from the first storage area 102.In certain implementations, the termination region 108 is spaced forwardly of the second storage region 104, which is spaced forwardly of the first storage region 102 (e.g., see FIG.\",\n \"4).\",\n \"In certain implementations, the second storage area 104 forms part of a protected fiber management region 106 at which optical fibers can be separated out from optical cables.\",\n \"At least a first fiber cable (e.g., distribution cable) 180 and at least a second cable (e.g., subscriber cable) 190 enter the housing 110 through cable ports 101.Fibers 192 of the second fiber cable 190 are routed to the termination region 108.The first fiber cable 180 is routed to the first storage area 102 of the cable spool arrangement 130.From the first storage area 102, the first fiber cable 180 is routed to the second storage area 104.The first fiber cable 180 is broken out into individual optical fibers 182 at the protected fiber management region 106.The fibers 182 are routed to the termination region 108 at which the optical fibers 184 are connected to optical fibers 192 of the second fiber cable 190.The fiber optic enclosure 100 provides an enclosure from which lengths of a cable (e.g., a distribution cable) 180 can be dispensed following the mounting of the fiber optic enclosure 100 to a mounting location.\",\n \"The distribution cable 180 is dispensed from the fiber optic enclosure 100 by pulling on an end (e.g., a connectorized end) 185 of the cable 180 (see FIGS.\",\n \"4 and 7).\",\n \"As the distribution cable 180 is dispensed, the cable spool arrangement 130 rotates about an axis relative to the stationary mounting plate 121 of the fiber optic enclosure 100.In the event that there is a residual length of distribution cable 180 that is not dispensed during the cable payout, the fiber optic enclosure 100 can store this residual length.\",\n \"As shown in FIG.\",\n \"6, the cable spool mounting assembly 120 includes a mounting plate 121 and a cable spool arrangement 130.The mounting plate 121 includes a first side 124 and an opposite second side 123.The mounting plate 121 is adapted for stationary mounting to the rear wall 115 of the housing enclosure.\",\n \"In certain implementations, the second side 123 of the mounting plate 121 is configured to be mounted to an interior surface of the rear wall 115 so that the mounting plate 121 is disposed within the interior of the housing enclosure 110.For example, in certain implementations, the mounting plate 121 defines one or more fastener openings 122 that are disposed to align with fastener openings provided on the rear wall 115 of the housing enclosure 110.Certain types of mounting plates 121 extend along substantially the entire rear wall 115 of the enclosure housing 110.The cable spool arrangement 130 includes a drum 131 extending between first and second support flanges 132, 133 to form a first cable spool 134.The first cable spool 134 defines the first storage region 102 (FIG.\",\n \"5).\",\n \"In some implementations, the cable spool arrangement 130 also includes a termination region 108 (FIG.\",\n \"5).\",\n \"In certain implementations, a protected fiber management region 106 (FIG.\",\n \"5) is defined between the first storage region 102 and the termination region 108.For example, in certain implementations, in FIG.\",\n \"6, the cable spool arrangement 130 includes a stand-off mounting assembly 140, at which the termination region 108 (FIG.\",\n \"5) is disposed as will be described in more detail herein.\",\n \"The protected fiber management region 106 (FIG.\",\n \"5) is defined between the stand-off mounting assembly 140 and one of the first cable spool 134 (e.g., see FIG.\",\n \"4).\",\n \"In certain implementations, the drum portion 131 of the first cable spool 134 is generally cylindrical in shape.\",\n \"The drum portion 131 includes a first end portion that couples to the first support flange 132 and an oppositely disposed second end portion that couples to the second support flange 133.The support flanges 132, 133, which are generally parallel to each other, are configured to rotate with the drum 131.An outer surface of the drum 131 and inner surfaces of the support flanges 132, 133 define the first storage region 102 (FIG.\",\n \"5) within which optical fibers or cables (e.g., distribution cable 180) may be coiled.\",\n \"The drum portion 131 has a sufficient diameter to provide bend radius protection to optical fibers wound around the fiber spool 134.The drum portion 131 defines a central bore that extends through the drum portion 131.In the subject embodiment, the central bore is adapted to receive a spindle 129 (FIG.\",\n \"6).\",\n \"In certain implementations, the spindle 129 extends through the bore in the drum 131 and secures to the second side 123 of the mounting plate 121.For example, in certain implementations, the mounting plate 121 defines openings 125 at which the spindle 129 is fastened to the mounting plate 121.The first cable spool 134 is configured to rotate about the spindle 129 relative to the mounting plate 121.The support flanges 132, 133 are sized and shaped to retain the optical fibers wound around the drum 131 in the first storage region 102.In some implementations, the support flanges 132, 133 are generally circular.\",\n \"In certain implementations, the support flanges 132, 133 have a sufficient diameter to cover a majority of a surface area of the mounting plate 121.In other implementations, however, one or both of the support flanges 132, 133 may have a smaller diameter.\",\n \"In some implementations, the cable spool arrangement 130 is configured to be releasably locked in a rotationally fixed position relative to the mounting plate 121.For example, in certain implementations, the mounting plate 121 includes a forwardly extending flange 126 that is configured to extend past the support flanges 132, 133 of the drum 131 to interact with the front of the cable spool arrangement 130 (see FIG.\",\n \"6).\",\n \"The forwardly extending flange 126 defines an opening 127.The second flange 133 of the cable spool 134 defines an opening 136 that is disposed to align with the opening 127 of the forwardly extending flange 126 when the cable spool arrangement 130 is disposed in one rotational position.\",\n \"In certain implementations, the opening 136 is defined in a tab 135 that extends outwardly from the generally annular circumference of the second support flange 133.A fastener 128 may be inserted through the openings 136, 127 to lock the cable spool arrangement 130 in the rotationally fixed position.\",\n \"In some implementations, the second support flange 133 of the cable spool 134 defines an aperture 139 through which optical fibers or cables (e.g., distribution cable 180) may pass between the first storage area 102 and the front of the cable spool 134.In certain implementations, the cables pass through aperture 139 from the first storage region 102 to the protected fiber management region 106.For example, in certain implementations, the aperture 139 is located directly adjacent to the protected fiber management region 106 and allows cables from inside the first storage region 102 of the spool to be routed from the drum surface 131 to the protected storage region 106.The protected fiber management region 106 (FIG.\",\n \"5) provides a mounting location for a fan out arrangement.\",\n \"The fan out arrangement includes one or more fan outs 138 disposed between the back side of the stand-off 140 and the front side of the cable spool 134 (see FIG.\",\n \"4).\",\n \"For example, the fan outs 138 may be disposed on the front side of the second support flange 133 of the cable spool 134.Accordingly, the fan outs 138 rotate with the cable spool 134.The cable 180 wrapped around the supplemental spool region 104 can be routed to one of the fan outs 138 where individual optical fiber are broken out to form individual fiber optic pigtails 182.The pigtails 182 have ends connectorized by fiber optic connectors that are inserted into the fiber optic adapters 147 at the termination field 108 (see FIG.\",\n \"4).\",\n \"Fiber optic connectors corresponding to fibers 192 of subscriber cables 190 also may be inserted into the adapters 147 to provide optical connections between the subscriber cables 190 and the cables 180 routed from the first cable spool 134.The protected fiber management region 106 also can include bend radius protectors 137 attached to the front spool flange 133 (FIG.\",\n \"6).\",\n \"The bend radius protector 137 can form a supplemental spooling region 104 where cables routed from drum 131 through aperture 139 can be wrapped/spooled to provide cable storage and cable management.\",\n \"The pigtails 182 also may be wrapped/spooled around the bend radius limiters 137.In some implementations, the supplemental spooling region 104 provides strain relief to the cables (e.g., distribution cables) 180.Axial loads applied to the outside end 185 of the cables 180 will be transferred through the cable 180 to the wrapped portions of the cable 180.However, the axial loads will not be transferred to the connectorized ends of the pigtails 182.Accordingly, pulling on the first cable end 185 will not detach the connectorized pigtails 182 from the adapters 147 at the termination region 108.Still referring to FIGS.\",\n \"4-7, a stand-off mount element 140 may be coupled to the front of the first cable spool 134.For example, the stand-off mount element 140 may be secured to the second support flange 133 of the first cable spool 134 so that the stand-off mount element 140 unitarily rotates with the first cable spool 134.The stand-off mount element 140 provides a front plate 141 where optical components (e.g., fiber optic adapters, splitters, splice trays, spools, bend radius protector, etc.)\",\n \"can be mounted.\",\n \"For example, fiber optic adapters 147 may form a termination region 108 on the front plate 141.Cable management structures (e.g., bend radius limiters, spools, etc.)\",\n \"148 also may be provided on the stand-off plate 141.In the example shown, two opposing bend radius limiters 148 form a fiber spool on the stand-off plate 141.In certain implementations, one or more legs 142 extend rearwardly from the stand-off plate 141 of the stand-off mount element 140.Each leg 142 defines an opening 143 configured to receive a peg 145 or fastener to secure the feet 143 to the front support flange 133 of the cable spool 134.In the example shown, the stand-off mount element 140 includes four legs 142.In other implementations, however, the stand-off mount element 140 may include greater or fewer legs 142.In still other implementations, the legs 142 may be unitary with the cable spool 134 and secure to the stand-off plate 141.The stand-off plate 141 is forwardly offset from the front side of the spool flange 133, thereby forming the protected fiber management region 106 between the front side of the first cable spool 134 and back side of the stand-off mount element 140 (e.g., see FIG.\",\n \"4).\",\n \"The separated fibers 184 in the protected fiber management region 106 are routed around the bend radius limiters 137 or other management structures on the front of the cable spool 134 to the stand-off mount element 140.In the example shown, the separated fibers 184 have connectorized ends that plug into first ports of termination adapters 147 disposed at the stand-off plate 141.Components disposed on the stand-off mount element 140 are spaced forwardly of the cable spool 134.Accordingly, the fiber optic adapters 147 are disposed on a different layer or plane than the fan outs 138, which are disposed on a different layer or plane than the first cable spool 134.In certain implementations, the fan outs 138 are disposed on the same layer or plane as the bend radius limiters 137.The spacing between the cable spool layer and the stand-off layer enhances slack storage of optical fibers routed through the protected fiber management region 106.In some implementations, the spacing between the cable spool layer and the stand-off layer inhibits over-bending of the fibers when routed between the fan out arrangements 138 and the fiber optic adapters 147.In certain implementations, the termination adapters 147 are included in one or more termination modules 146.In certain implementations, the adapter modules 146 are sliding adapter modules.\",\n \"Similar sliding adapter modules have been described in commonly

management factor associated with the retail sales facility and at least one worker task event associated with the at least one product; and output to a user at the retail sales facility, based on the tracking of the location of the at least one product, an indication of a predicted location of the least one product.","Referring to FIG.","1, one embodiment of a system 100 for tracking and/or locating out of stock products at a retail sales facility 110 is shown.","The retail sales facility 110 may be any place of business such as a store or warehouse where consumer products are stocked and/or sold.","The system 100 includes an inventory management electronic device 120 configured to manage product inventory at the retail sales facility 110.The inventory management electronic device 120 illustrated in FIG.","1 may be a stationary, portable, or hand-held electronic device, for example, a desktop computer, a laptop computer, a tablet, a mobile phone, or any other electronic, processor-based device that may be configured for data entry and communication with another electronic, processor-based device located at the retail sales facility 110, or at a location remote to the retail sales facility 110 (e.g., a regional or central server configured for two-way communication with multiple retail sales facilities 110).","The exemplary inventory management electronic device 120 shown in FIG.","1 includes an inventory management database 140 configured to store information regarding the items 90 present at the retail sales facility 110.The inventory management database 140 may be stored, for example, on non-volatile storage media (e.g., a hard drive, flash drive, or removable optical disk) internal or external relative to the inventory management electronic device 120 or internal to computing devices (e.g., remote server) separate and distinct from the inventory management electronic device 120.The information regarding the items 90 stored on the inventory management database 140 may include various historical/statistical inventory management factors pertaining to the retail sales facility 110 and worker task events pertaining to the items 90, which are shown in FIG.","4, and will be discussed in more detail below.","FIG.","1 schematically shows (via dotted lines 155, 165, and 175) that the inventory management database 140 contains information regarding the items 90 present in the product delivery area 160, stock room 170, sales floor 180, and product sale/return/claim areas 190 of the retail sales facility 110, but it will be appreciated that the inventory management database 140 may contain information regarding any items 90 present in any other area of the retail sales facility 110 and may include information relating to tasks performed by workers in any other area of the retail sales facility 110 with respect to the items 90.The items 90 may be identified in the inventory management database 140 by way of stock keeping unit (SKU) numbers or any other unique identifiers.","It will be appreciated that the inventory management database 140 does not have to be incorporated into the inventory management electronic device 120 local to the retail sales facility 110, but may be stored on a remote (e.g., central) server in communication with the inventory management electronic device 120.An exemplary inventory management electronic device 120 depicted in FIG.","2 is a computer-based device and includes a control circuit 210 including a processor (for example, a microprocessor or a microcontroller) electrically coupled via a connection 215 to a memory 220 and via a connection 225 to a power supply 230.The control circuit 210 can comprise a fixed-purpose hard-wired platform or can comprise a partially or wholly programmable platform, such as a microcontroller, an application specification integrated circuit, a field programmable gate array, and so on.","These architectural options are well known and understood in the art and require no further description here.","This control circuit 210 can be configured (for example, by using corresponding programming stored in the memory 220 as will be well understood by those skilled in the art) to carry out one or more of the steps, actions, and/or functions described herein.","In some embodiments, the memory 220 may be integral to the control circuit 210 or can be physically discrete (in whole or in part) from the control circuit 210 and is a non-volatile data storage media such as a hard drive configured to store the inventory management database 140.The memory 220 can be configured non-transitorily store the computer instructions that, when executed by the control circuit 210, cause the control circuit 210 to behave as described herein.","(As used herein, this reference to “non-transitorily” will be understood to refer to a non-ephemeral state for the stored contents (and hence excludes when the stored contents merely constitute signals or waves) rather than volatility of the storage media itself and hence includes both non-volatile memory (such as read-only memory (ROM)) as well as volatile memory (such as an erasable programmable read-only memory (EPROM)).)","The control circuit 210 of the electronic device 120 is also electrically coupled via a connection 235 to an input/output 240 that can receive signals from and send signals (via a wired or wireless connection) to (e.g., commands, inventory database information) devices local to the retail sales facility 110, or one or more servers remote to the retail sales facility 110.In the embodiment shown in FIG.","2, the control circuit 210 of the electronic device 120 is electrically coupled via a connection 245 to a user interface 250, which may include a visual display or display screen 260 (e.g., LED screen) and/or button input 270 that provide the user interface 250 with the ability to permit a user such as a stock room or sales floor associate at the retail sales facility 110 to manually control the inventory management electronic device 120 by inputting commands, for example, via touch-screen and/or button operation or voice commands.","The display screen 260 can also permit the user to see various menus, options, and/or alerts displayed by the inventory management electronic device 120.The user interface 250 of the inventory management electronic device 120 may also include a speaker 280 that may provide audible feedback (e.g., alerts) to the user.","With reference to FIGS.","1-3, one method 300 of operation of the system 100 to track and located out of stock products 90 at a retail sales facility 110 will now be described.","For exemplary purposes, the method is described in the context of the system of FIG.","1, but it is understood that embodiments of the method may be implemented in this or other systems.","Generally, as shown in FIG.","3, the method 300 includes receiving, an indication that a product 90 at the retail sales facility 110 is out of stock (step 310).","Such an indication may be received as a result of a customer approaching a sales or stocking associate at the retail sales location 110 to inform the sales or stocking associate that the product 90 is not present on a shelf on the sales floor 180 where this product 90 is normally stocked.","Alternatively, the consumer may inform the sales or stocking associate that the product 90 is out of stock after entering an SKU or an item identifier into an inventory management device available to consumers (e.g., by scanning a floor sample of the product 90 using an inventory management scanner) and receiving an indication that the product 90 is out of stock at the retail sales location 110.Alternatively, the out of stock indication may come as a result of a sales or stocking associate either scanning the floor sample of the product 90 or otherwise entering information identifying the product 90 into the inventory management database 140 (e.g., using the inventory management electronic device 120) and receiving an alert that the product 90 is out of stock.","In the embodiment shown in FIG.","3, the method 300 further includes determining whether the product 90 is located on a sales floor 180 at the retail sales facility 110 (step 320).","This determination may be made as a result of the stocking associate at the retail sales facility 110 entering identifying information regarding the out of stock item 90 into the inventory management electronic device 120, in response to which the processor of the control circuit 210 of the inventory management electronic device 120 may be programmed to send an appropriate query or signal to the inventory management database 140 internal to the inventory management electronic device 120, or to a remote inventory management database via the input/output 240.In one embodiment, the inventory management database 140, upon receiving such a query or signal including data identifying the item 90 can retrieve information regarding the current location of the item 90 at the retail sales facility 110, and more specifically, regarding whether the item 90 is presently located on a shelf on the sales floor 180 where the item 90 is normally stocked for display and sale to consumers.","In some embodiments, if the information retrieved from the inventory management database 140 indicates that the item 90 is present on a shelf on the sales floor 180 of the retail sales facility 110, the processor of the control circuit 210 is programmed to send a signal to the display 260 and/or speaker 280 of the inventory management electronic device 120 to generate a visible alert (e.g., via the on-screen menu) or an audible alert (e.g., beep or voice command) to inform the user (e.g., stocking associate) that the item 90 is present on the shelf on the sales floor 180.It will be appreciated that instead of retrieving information related to the present location of the item 90 at the retail sales facility 110 from the inventory management database 140, such information may be retrieved by the inventory management electronic device 120 from an inventory management database remote to the retail sales facility 110.In one embodiment shown in FIG.","3, in response to a determination by the processor of the control circuit 210 of the inventory management electronic device 120 that the product 90 is not located on the sales floor 180 at the retail sales facility 110, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to determine whether the product 90 is located in the stock room 170 at the retail sales facility 110 (step 330).","As described above, this determination may be made as a result of the stocking associate at the retail sales facility 110 entering identifying information regarding the out of stock item 90 into the inventory management electronic device 120, in response to which the processor of the control circuit 210 of the inventory management electronic device 120 may be programmed to send an appropriate query or signal to the inventory management database 140, and the inventory management database 140, upon receiving such a query or signal including data identifying the item 90 can retrieve information regarding the current location of the item 90 at the retail sales facility 110, and more specifically, regarding whether the item 90 is presently located in the stock room 170.If the information retrieved from the inventory management database 140 indicates that the item 90 is in the stock room 170 of the retail sales facility 110, the processor of the control circuit 210 of the inventory management electronic device 120 may be programmed to send a signal to the display 260 or speaker 280 of the inventory management electronic device 120 to generate a visible alert (e.g., via the on-screen menu) or an audible alert (e.g., beep or voice command) to inform the user (e.g., stocking associate) that the item 90 is in the stock room 170.In one embodiment shown in FIG.","3, in response to a determination by the processor of the control circuit 210 of the inventory management electronic device 120 that the product 90 is not located on the sales floor 180 or in the stock room 170 at the retail sales facility 110, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to track the location of the out of stock product 90 at the retail sales facility 110 based on at least one inventory management factor associated with the retail sales facility 110 and/or at least one worker task event associated with the product 90 (step 340).","The inventory management factors and worker task events that the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to analyze in tracking the location of the product 90 at the retail sales facility 110 are depicted in FIG.","4 and discussed in more detail below.","Based on the tracking analysis by the processor of the control circuit 210 of the inventory management electronic device 120, which will be described in more detail below, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to output an indication of a perceived or predicted location of the product 90 (step 350).","The perceived location may be a physical location at the retail sales facility 110 such as the stock room 170, sales floor 180 or any other location at the retail sales facility 110 determined by the processor of the control circuit 210 of the inventory management electronic device 120 to contain the product 90.Alternatively, the output of the tracking analysis may be an indication that the product 90 is not present at the retail sales facility 110.For example, based on the tracking analysis, the processor of the control circuit 210 of the inventory management electronic device 120 may be programmed to send signal to the display 260 or speaker 280 of the inventory management electronic device 120 to generate a visible alert (e.g., via the on-screen menu) or an audible alert (e.g., beep or voice command) to inform the user (e.g., stocking associate) that the item 90 is perceived to be in the stock room 170, on the sales floor 180, or not present at the retail sales facility 110.Such an alert would signal to the stocking associate to take appropriate action (e.g., retrieve the item 90 from the perceived location for the consumer) or inform the consumer seeking the item 90 at the retail sales facility 110 that the item 90 is not present at the retail sales facility 110.In one embodiment, when the inventory management electronic device 120 indicates (e.g., via a visual or audible alert), based on tracking the item 90, to the stocking associate that the item 90 may be stocked on a shelf on the sales floor 180 or in the stock room 170, the inventory management electronic device 120 presents the associate with an option to acknowledge the alert, for example, by pressing on the display screen 260 or on one of the inputs 270 of the inventory management electronic device 120.When the stocking associate physically confirms whether the perceived location (i.e., based on the tracking analysis) of the item 90 is correct by walking to the perceived location and attempting to retrieve the item 90 and responds to the alert by indicating (e.g., via using the inputs 270 of the inventory management electronic device 120) whether the perceived location of the item 90 is correct or incorrect, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to designate the product 90 as being located in the location perceived based on the tracking analysis, or as being in an unidentified location at the retail sales facility 110, or as being not present at the retail sales facility 110.For example, the processor of the control circuit 210 may be programmed to send a signal to the inventory management database 140 or, via the input/output 240, to an inventory management database on a remote server, to indicate the actual physical location of the item 90 at the retail sales facility 110.As such, the location of the item 90 at the retail sales facility 110 may be updated in the inventory management database 140 or remote inventory management database for the retail sales facility 110, which enables the inventory management database 140 and/or a remote database to systematically store updated information regarding the location of items 90 indicated to be out of stock at the retail sales facility 110 and to permit the associates to efficiently retrieve such items and provide them to consumers seeking to buy these items 90.An exemplary method 400 of managing and stocking of products 90 at the retail sales facility 110 will now be described with reference to FIGS.","1 and 4.As shown generally in step 410, when a stocking associate wishes to identify the location of a product 90 indicated to the customer or the stocking associate to be out of stock (step 410), the inventory management electronic device 120 may be initially operated by the stocking associate to determine, as described above, whether the item 90 (indicated to be out of stock) is present in a primary location at the retail sales facility 110 (step 420).","The primary location may be, for example, a shelf on the sales floor 180 at the retail sales facility 110 where the item 90 is normally offered for sale to the customers.","If the inventory management electronic device 120 indicates (e.g., via a displayed message, beep, or spoken words as discussed above) to the stocking associate that the item 90 is present in the primary location (step 425), the tracking process ends (step 430), enabling the stocking associate to physically check the primary location in an attempt to find the item 90 and provide it to the customer.","Alternatively, if the inventory management electronic device 120 indicates (e.g., via a displayed message, beep, or spoken words as discussed above) to the stocking associate that the item 90 is not present in the primary location (step 435), the stocking associate may then operate the inventory management electronic device 120 to determine, as described above, whether the item 90 indicated to be out of stock is present in a secondary location at the retail sales facility 110 (step 440).","The secondary location may be a location on the sales floor 180 other than the shelf where the item 90 is normally offered for sale to the customers, such as, for example, a feature, seasonal, or discount display on the sales floor 180.In yet another alternative, instead of relying on the inventory management electronic device 120 for a determination of whether the item 90 is present in the primary location, the stocking associate may walk to the primary location of the item 90 on the sales floor and visually inspect the primary location of the item 90 on the sales floor 180 to determine whether the item 90 indicated to be out of stock is present at the primary location.","Upon the visual inspection, the stocking associate may then enter information into the inventory management system 100 using the inventory management electronic device 120 to indicate whether the item 90 is or is not present at the primary location at the retail sales facility 110.If the inventory management electronic device 120 indicates (e.g., via a displayed message, beep, or spoken words as discussed above) to the stocking associate that the item 90 is present in the secondary location (step 445), the tracking process ends (step 450), enabling the stocking associate to physically check the secondary location in an attempt to find the item 90 and provide it to the customer.","Alternatively, if the inventory management electronic device 120 indicates (e.g., via a displayed message, beep, or spoken words as discussed above) to the stocking associate that the item 90 is not present in the secondary location (step 455), the stocking associate may then operate the inventory management electronic device 120 to determine, as described above, whether the item 90 indicated to be out of stock is present in the back room or stock room 170 at the retail sales facility 110 (step 460).","If the inventory management electronic device 120 indicates (e.g., via a displayed message, beep, or spoken words as discussed above) to the stocking associate that the item 90 is present in the stock room 170 (step 465), the tracking process ends (step 470), enabling the stocking associate to physically check the stock room 170 in an attempt to find the item 90 and provide it to the customer.","Alternatively, if the inventory management electronic device 120 indicates (e.g., via a displayed message, beep, or spoken words as discussed above) to the stocking associate that the item 90 is not present in the stock room 170 (step 475), the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to track the location of the item 90 at the retail sales facility 110 using predetermined inventory management factors 480 associated with the retail sales facility 110, as shown in FIG.","4.It will be appreciated that the ten inventory management factors depicted in FIG.","4 are shown by way of example only, and the processor of the control circuit 210 of the inventory management electronic device 120 may be programmed to analyze any one or more of these inventory management factors (or additional inventory management factors) to determine a predicted location of an out of stock item 90 at the retail sales facility 110.It will appreciated that the tracking of the out of stock items 90 at the retail sales facility 110 may be performed without requiring any calculation or analysis by the processor of the control circuit 210 of the inventory management electronic device 120, and that the system 100 may be configured such that the tracking of the out of stock items 90 may be performed by an inventory management computing device remote to the retail sales facility 110 and in communication with the inventory management electronic device 120.In such embodiments, the tracking analysis of the out of stock item 90 may be performed by the inventory management computing device remote to the grocery location 110 (based on data stored in the inventory management database 140 or a remote inventory management database), and may be stored at the remote inventory management database or in the inventory management database 140 until a time when a user uses the electronic computing device 120 to request and retrieve the perceived location of the out of stock item 90 from the remote inventory management database or the inventory management database 140, as appropriate.","With reference to FIG.","4, the exemplary inventory management factors that may be used for the tracking of the out of stock items 90 are: (1) mis-rings; (2) shipping error; (3) sales floor quantity versus shelf cap; (4) change in on-hand inventory at the retail sales facility; (5) bin accuracy; (6) perpetual inventory accuracy; (7) modular integrity; (8) shrink; (9) replenishment method; and (10) pick completion.","Each factor is discussed in more detail below.","Factor 1, Mis-Rings, refers to the data stored in the inventory management database 140 indicating that a cashier at a cash register did not correctly scan an item 90 (or did not for some reason scan all of the items 90) during a sale or return of the item 90.In some embodiments, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to interpret a higher value of Mis-Rings at the retail sales facility 110 as representing a higher likelihood that the system-indicated location/status of the item 90 is incorrect, and that the item 90 may be out of stock and not present at the retail sales facility 110.Factor 2, Shipping Error, refers to the data stored in the inventory management database 140 indicating that the number of items 90 indicated in shipping slips or in the system inventory database as being shipped to the retail sales facility 110 was incorrect.","For example, a shipping error may be generated when the system indicates that 1000 items 90 were shipped to the retail sales facility 110 when in fact it was determined that only 980 or 990 items 90 were shipped to the retail sales facility 110.In some embodiments, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to interpret a higher value of Shipping Error at the retail sales facility 110 as representing a higher likelihood that the system-indicated location/status of the item 90 is incorrect, and that the item 90 may be out of stock and not present at the retail sales facility 110.Factor 3, SF>SC (sales floor quantity greater than shelf cap), refers to the data stored in the inventory management database 140 indicating that the number of items 90 indicated to be on the sales floor 180 at the retail sales facility 110 is greater than the shelf space where the items 90 are typically stored.","In some embodiments, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to interpret a higher number of SF>SC occurrences at the retail sales facility 110 as representing a higher likelihood that the system-indicated location of the item 90 as being out of stock is incorrect, and that the item 90 may be elsewhere on the sales floor 180 or in another area of the retail sales facility 110.Factor 4, OH Delta (on-hand change), refers to the data stored in the inventory management database 140 indicating a change in the total number of items 90 in stock (i.e., on-hand) at the retail sales facility 110.In some embodiments, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to interpret a higher OH Delta value as representing a higher likelihood that the system-indicated location of the item 90 as being on the sales floor 180 of the retail sales facility 110 is incorrect, and that the item 90 is may be out of stock at the retail sales facility 110.Factor 5, Bin Accuracy, refers to the data stored in the inventory management database 140 reflecting the accuracy of the systematic indication of the location of an item 90 by the stocking associates at the retail sales facility 110.For example, if the number of items 90 entered into the system as being present in a storage bin by a stocking associate corresponds to actual number of items 90 in the storage bin when physically checked, or when the system indicates that the item 90 is not present in a storage bin and the item 90 is actually not present in the storage bin when physically checked, the bin accuracy value would be high for the retail sales facility 110, and vice versa.","In some embodiments, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to interpret a lower Bin Accuracy value as representing a higher likelihood that the system-indicated location and status of the item 90 at the retail sales facility 110 is incorrect and vice versa.","Factor 6, PI Accuracy (or perpetual accuracy), refers to the data stored in the inventory management database 140 reflecting the accuracy of the inventory location designation by the stocking associates at the retail sales facility 110.This factor generally indicates whether the items 90 are generally located where the system indicates they are located.","In some embodiments, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to interpret a lower PI Accuracy value as representing a higher likelihood that the system-indicated location and status of the item 90 at the retail sales facility 110 is incorrect and vice versa.","Factor 7, Mod Integrity (or modular planogram integrity), refers to the data stored in the inventory management database 140 indicating how correctly the stocking associates at the retail sales facility 110 stock the shelf on the sales floor 180 with the items 90 and/or how correctly the shelf on the sales floor 180 is set up for the items 90.This factor generally indicates whether the actual layout of the items 90 on the sales floor of the retail sales facility 110 corresponds to the layout of the items 90 according to the inventory management system 10.In some embodiments, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to interpret a lower PI Accuracy value as representing a higher likelihood that the system-indicated location and status of the item 90 at the retail sales facility 110 is incorrect and vice versa.","Factor 8, shrink, indicates how often items 90 go missing or unaccounted for at the retail sales facility 110 (e.g., as a result of theft, supplier mistakes, or other paperwork errors).","In some embodiments, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to interpret a higher shrink value as representing a higher likelihood that the item 90 is not present at the retail sales facility 110 and vice versa.","Factor 9, Replen Method (or replenishment method) indicates whether the item 90 moves quickly or slowly and is replenished quickly or slowly at the retail sales facility 110.The replenishment method may be indicated as a high velocity distribution center (HVDC) or a regional distribution center (RDC).","If the replenishment method is indicated as HVDC, the item 90 is replenished quickly and has high turnover, while an RDC replenishment method is indicative of items 90 that have low turnover and move slowly.","Accordingly, in some embodiments, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to interpret an HVDC replenishment method as generally indicating a higher likelihood that the system-indicated location or status of the item 90 at the retail sales facility 110 is incorrect, and to interpret the RDC replenishment method as generally indicating a higher likelihood that the system-indicated location or status of the item 90 at the retail sales facility 110 is correct.","Factor 10, Pick Completion, indicates how often when the system indicates to an associate to pick an item 90 (e.g., from a storage bin) that the associate actually completes the pick.","For instance, a low pick completion percentage may indicate that a stocking associate is not operating efficiently but likely honestly; an average pick completion may indicate that a stocking associate is operating within the norm of expected efficiency and honesty; a high pick completion may indicate that an associate may be entering into the system that the associate picked an item while the associate is not physically picking the item.","Thus, in some embodiments, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to interpret a high pick completion percentage at the retail sales facility 110 as indicative of a higher likelihood that the system-indicated location or status of the item 90 at the retail sales facility 110 is incorrect.","In the exemplary embodiment illustrated in FIG.","4, in addition to the ten exemplary inventory management factors discussed above based on which a perceived location of the out of stock item 90 may be tracked at the retail sales facility 110, the processor of the control circuit 210 of the inventory management electronic device 120 may be programmed to track the location of the item 90 at the retail sales facility 110 using predetermined worker task events 490 associated with the product 90.It will be appreciated that the nine worker task events 490 depicted in FIG.","4 are shown by way of example only, and any one or more of these worker task events 490 (or additional worker task events) may be analyzed by the processor of the control circuit 210 of the inventory management electronic device 120 to determine a perceived location of an out of stock item 90 at the retail sales facility 110.The exemplary worker task events are identified in FIG.","4 by numbers that continue the numbering from the last inventory management factor and are as follows: (11) time stamp of last sale of the item 90 to a customer; (12) time stamp of last customer return of the item 90; (13) time stamp of last customer claim for the item 90 (i.e., product indicated as not sellable); (14) time stamp of last binning or unbinning of the item 90; (15) time stamp of last feature set or unset of the item 90 (i.e., product is displayed as a featured item on the sales floor 180); (16) time stamp of last delivery of the item 90; (17) time stamp of last scan of the item 90; (18 ) time stamp of last price change of the item 90; and (19) time stamp of pick of the item 90.In one embodiment, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to track the location of the item 90 at the retail sales facility 110 using the inventory management factors 480 and the worker task events 490 described above and output a perceived location of the item 90 at the retail sales facility 110 based on the tracking analysis.","Some exemplary output of the processor of the control circuit 210 of the inventory management electronic device 120 based on the above-discussed inventory management factors (F1, F2, F3, etc.)","and worker task events (T11, T12, T13, etc.)","are discussed below.","It will be appreciated that output of the processor of the control circuit 210 of the inventory management electronic device 120 regarding the perceived location of an out of stock item 90 at the retail sales facility 110 may be based on many different combinations of one or more of the above-discussed inventory management factors 480 and/or worker task events 490, or may be based on combinations including additional inventory management factors 480 and additional worker task events 490 suitable for tracking a location of the out of stock item 90 at the retail sales facility 110.For example, the processor of the control circuit 210 of the inventory management electronic device 120 may be programmed to output that the item 90 is not present (i.e., out of stock) at the retail sales facility 110 if at least one of the following eight conditions is met during the tracking analysis: (1) if bin accuracy (F5) or perpetual accuracy (F6) or modular planogram integrity (F7) or pick completion percentage (F10) are low, and shrink (F8) or shipping error (F2) or mis-rings (F1) are high; (2) if time stamp of last delivery (T16) is newest and then the time stamp of last sale (T11) is newest, and on-hand delta (F4) is low; (3) if shrink (F8) is high; (4) if time stamp of last scan is newest (T17), and then timestamp of last sale is newest (T11), and then time stamp of last delivery (T16) is newest; (5) if the replenishment method (F9) is RDC assembly; (6) if on-hand delta (F4) is high and/or perpetual accuracy (F6) is low; (7) if time stamp of last price change newest (T18) and on-hand delta (F4) is high and/or perpetual accuracy (F6) is low; and (8) if the answer is “no” on all worker task events.","Some other exemplary outputs of the control circuit 210 of the inventory management electronic device 120 and the inventory management factors 480 and worker task events 490 contributing to such outputs are described below.","If SF>SC (F3) and time stamp of last delivery is newest (T16), and then time stamp of last pick is newest (T19), or time stamp of last sale is newest (T11), or time stamp of last claim is newest (T13), or time stamp of last bin or unbin is newest (T14), or time stamp of last return is newest (T12), or time stamp of last scan is newest (T17), then the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to output an indication to a stocking associate to look for the item 90 in the unworked freight.","If the replenishment method (F9) is determined to be HVDC, then the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to output an indication to a stocking associate to look for the item 90 in unbinned locations or previous binned area of the retail sales facility 110.If the time stamp of last claim is newest (T13), then the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to output an indication to a stocking associate to look for the item 90 in the claims area of the retail sales facility 110.If the time stamp of last return is newest (T12), then the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to output an indication to a stocking associate to look for the item 90 in the claims or returns area of the retail sales facility 110.If the time stamp of last pick is newest (T19) and pick completion (F10) is high, then the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to output an indication to a stocking associate to look for the item 90 in the pick carts in the stock room 170 of the retail sales facility 110.If modular planogram integrity (F7) is low, then the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to output an indication to a stocking associate to look for the item 90 in an area near the primary location on the sales floor 180 of the retail sales facility 110.If the time stamp of last pick is newest (T19) and pick completion (F10) or bin accuracy (F5) are low, then the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to output an indication to a stocking associate to look for the item 90 in the bin where the item 90 was indicated to be previously stored at the retail sales facility 110.If the time stamp of last bin or unbin is newest (T14) and pick completion (F10) or bin accuracy (F5) are low, then the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to output an indication to a stocking associate to look for the item 90 in the bin where the item 90 was indicated to be previously stored at the retail sales facility 110.If the time stamp of last feature set newest (T15), then the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to output an indication to a stocking associate to look for the item 90 in feature locations on the sales floor 180 or unbinned in the stock room 170 of the retail sales facility 110.In one approach, the processor of the control circuit 210 of the inventory management device 120 is programmed to monitor whether one or more worker task events 490 entered into the inventory management database 140 as being completed was in fact physically completed.","Based on this monitoring, the processor of the control circuit 210 of the inventory management device 120 is programmed to generate in the inventory management database 140 at least one data point indicating whether the one or more worker task event entered into the inventory management database 140 as being completed was physically completed.","In addition, the processor of the control circuit 210 of the inventory management device 120 is programmed to generate a report including at least one data point over a predetermined period of the monitoring.","The processor of the control circuit 210 of the inventory management device 120 is programmed to use such data points to generate an alert for items 90 for which a worker task was entered into the inventory management database 140 as being completed but was in fact not completed.","In addition, such data points can be used to determine a metric for the quality of stocking work by the inventory management associates at the retail sales facility 110.As described herein, the system and methods described herein provide for easy and efficient tracking and retrieval of out of stock inventory at a retail sales facility.","As discussed above, in a response to an indication that an item is out of stock at the retail sales facility, the methods and systems described herein can track the location of the out of stock item using one or more inventory management factors and worker task events described above and output an accurate perceived location of the item at the retail sales facility based on the tracking analysis.","This advantageously improves the efficiency of associates in determining whether items indicated to be out of stock are present at the retail sales facility, and if so, facilitates the stocking associates in tracking down and retrieving the items sought by the consumers and providing the retrieved items to the consumers.","Those skilled in the art will recognize that a wide variety of other modifications, alterations, and combinations can also be made with respect to the above described embodiments without

(e.g., alerts) to the user.\",\n \"With reference to FIGS.\",\n \"1-3, one method 300 of operation of the system 100 to track and located out of stock products 90 at a retail sales facility 110 will now be described.\",\n \"For exemplary purposes, the method is described in the context of the system of FIG.\",\n \"1, but it is understood that embodiments of the method may be implemented in this or other systems.\",\n \"Generally, as shown in FIG.\",\n \"3, the method 300 includes receiving, an indication that a product 90 at the retail sales facility 110 is out of stock (step 310).\",\n \"Such an indication may be received as a result of a customer approaching a sales or stocking associate at the retail sales location 110 to inform the sales or stocking associate that the product 90 is not present on a shelf on the sales floor 180 where this product 90 is normally stocked.\",\n \"Alternatively, the consumer may inform the sales or stocking associate that the product 90 is out of stock after entering an SKU or an item identifier into an inventory management device available to consumers (e.g., by scanning a floor sample of the product 90 using an inventory management scanner) and receiving an indication that the product 90 is out of stock at the retail sales location 110.Alternatively, the out of stock indication may come as a result of a sales or stocking associate either scanning the floor sample of the product 90 or otherwise entering information identifying the product 90 into the inventory management database 140 (e.g., using the inventory management electronic device 120) and receiving an alert that the product 90 is out of stock.\",\n \"In the embodiment shown in FIG.\",\n \"3, the method 300 further includes determining whether the product 90 is located on a sales floor 180 at the retail sales facility 110 (step 320).\",\n \"This determination may be made as a result of the stocking associate at the retail sales facility 110 entering identifying information regarding the out of stock item 90 into the inventory management electronic device 120, in response to which the processor of the control circuit 210 of the inventory management electronic device 120 may be programmed to send an appropriate query or signal to the inventory management database 140 internal to the inventory management electronic device 120, or to a remote inventory management database via the input/output 240.In one embodiment, the inventory management database 140, upon receiving such a query or signal including data identifying the item 90 can retrieve information regarding the current location of the item 90 at the retail sales facility 110, and more specifically, regarding whether the item 90 is presently located on a shelf on the sales floor 180 where the item 90 is normally stocked for display and sale to consumers.\",\n \"In some embodiments, if the information retrieved from the inventory management database 140 indicates that the item 90 is present on a shelf on the sales floor 180 of the retail sales facility 110, the processor of the control circuit 210 is programmed to send a signal to the display 260 and/or speaker 280 of the inventory management electronic device 120 to generate a visible alert (e.g., via the on-screen menu) or an audible alert (e.g., beep or voice command) to inform the user (e.g., stocking associate) that the item 90 is present on the shelf on the sales floor 180.It will be appreciated that instead of retrieving information related to the present location of the item 90 at the retail sales facility 110 from the inventory management database 140, such information may be retrieved by the inventory management electronic device 120 from an inventory management database remote to the retail sales facility 110.In one embodiment shown in FIG.\",\n \"3, in response to a determination by the processor of the control circuit 210 of the inventory management electronic device 120 that the product 90 is not located on the sales floor 180 at the retail sales facility 110, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to determine whether the product 90 is located in the stock room 170 at the retail sales facility 110 (step 330).\",\n \"As described above, this determination may be made as a result of the stocking associate at the retail sales facility 110 entering identifying information regarding the out of stock item 90 into the inventory management electronic device 120, in response to which the processor of the control circuit 210 of the inventory management electronic device 120 may be programmed to send an appropriate query or signal to the inventory management database 140, and the inventory management database 140, upon receiving such a query or signal including data identifying the item 90 can retrieve information regarding the current location of the item 90 at the retail sales facility 110, and more specifically, regarding whether the item 90 is presently located in the stock room 170.If the information retrieved from the inventory management database 140 indicates that the item 90 is in the stock room 170 of the retail sales facility 110, the processor of the control circuit 210 of the inventory management electronic device 120 may be programmed to send a signal to the display 260 or speaker 280 of the inventory management electronic device 120 to generate a visible alert (e.g., via the on-screen menu) or an audible alert (e.g., beep or voice command) to inform the user (e.g., stocking associate) that the item 90 is in the stock room 170.In one embodiment shown in FIG.\",\n \"3, in response to a determination by the processor of the control circuit 210 of the inventory management electronic device 120 that the product 90 is not located on the sales floor 180 or in the stock room 170 at the retail sales facility 110, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to track the location of the out of stock product 90 at the retail sales facility 110 based on at least one inventory management factor associated with the retail sales facility 110 and/or at least one worker task event associated with the product 90 (step 340).\",\n \"The inventory management factors and worker task events that the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to analyze in tracking the location of the product 90 at the retail sales facility 110 are depicted in FIG.\",\n \"4 and discussed in more detail below.\",\n \"Based on the tracking analysis by the processor of the control circuit 210 of the inventory management electronic device 120, which will be described in more detail below, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to output an indication of a perceived or predicted location of the product 90 (step 350).\",\n \"The perceived location may be a physical location at the retail sales facility 110 such as the stock room 170, sales floor 180 or any other location at the retail sales facility 110 determined by the processor of the control circuit 210 of the inventory management electronic device 120 to contain the product 90.Alternatively, the output of the tracking analysis may be an indication that the product 90 is not present at the retail sales facility 110.For example, based on the tracking analysis, the processor of the control circuit 210 of the inventory management electronic device 120 may be programmed to send signal to the display 260 or speaker 280 of the inventory management electronic device 120 to generate a visible alert (e.g., via the on-screen menu) or an audible alert (e.g., beep or voice command) to inform the user (e.g., stocking associate) that the item 90 is perceived to be in the stock room 170, on the sales floor 180, or not present at the retail sales facility 110.Such an alert would signal to the stocking associate to take appropriate action (e.g., retrieve the item 90 from the perceived location for the consumer) or inform the consumer seeking the item 90 at the retail sales facility 110 that the item 90 is not present at the retail sales facility 110.In one embodiment, when the inventory management electronic device 120 indicates (e.g., via a visual or audible alert), based on tracking the item 90, to the stocking associate that the item 90 may be stocked on a shelf on the sales floor 180 or in the stock room 170, the inventory management electronic device 120 presents the associate with an option to acknowledge the alert, for example, by pressing on the display screen 260 or on one of the inputs 270 of the inventory management electronic device 120.When the stocking associate physically confirms whether the perceived location (i.e., based on the tracking analysis) of the item 90 is correct by walking to the perceived location and attempting to retrieve the item 90 and responds to the alert by indicating (e.g., via using the inputs 270 of the inventory management electronic device 120) whether the perceived location of the item 90 is correct or incorrect, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to designate the product 90 as being located in the location perceived based on the tracking analysis, or as being in an unidentified location at the retail sales facility 110, or as being not present at the retail sales facility 110.For example, the processor of the control circuit 210 may be programmed to send a signal to the inventory management database 140 or, via the input/output 240, to an inventory management database on a remote server, to indicate the actual physical location of the item 90 at the retail sales facility 110.As such, the location of the item 90 at the retail sales facility 110 may be updated in the inventory management database 140 or remote inventory management database for the retail sales facility 110, which enables the inventory management database 140 and/or a remote database to systematically store updated information regarding the location of items 90 indicated to be out of stock at the retail sales facility 110 and to permit the associates to efficiently retrieve such items and provide them to consumers seeking to buy these items 90.An exemplary method 400 of managing and stocking of products 90 at the retail sales facility 110 will now be described with reference to FIGS.\",\n \"1 and 4.As shown generally in step 410, when a stocking associate wishes to identify the location of a product 90 indicated to the customer or the stocking associate to be out of stock (step 410), the inventory management electronic device 120 may be initially operated by the stocking associate to determine, as described above, whether the item 90 (indicated to be out of stock) is present in a primary location at the retail sales facility 110 (step 420).\",\n \"The primary location may be, for example, a shelf on the sales floor 180 at the retail sales facility 110 where the item 90 is normally offered for sale to the customers.\",\n \"If the inventory management electronic device 120 indicates (e.g., via a displayed message, beep, or spoken words as discussed above) to the stocking associate that the item 90 is present in the primary location (step 425), the tracking process ends (step 430), enabling the stocking associate to physically check the primary location in an attempt to find the item 90 and provide it to the customer.\",\n \"Alternatively, if the inventory management electronic device 120 indicates (e.g., via a displayed message, beep, or spoken words as discussed above) to the stocking associate that the item 90 is not present in the primary location (step 435), the stocking associate may then operate the inventory management electronic device 120 to determine, as described above, whether the item 90 indicated to be out of stock is present in a secondary location at the retail sales facility 110 (step 440).\",\n \"The secondary location may be a location on the sales floor 180 other than the shelf where the item 90 is normally offered for sale to the customers, such as, for example, a feature, seasonal, or discount display on the sales floor 180.In yet another alternative, instead of relying on the inventory management electronic device 120 for a determination of whether the item 90 is present in the primary location, the stocking associate may walk to the primary location of the item 90 on the sales floor and visually inspect the primary location of the item 90 on the sales floor 180 to determine whether the item 90 indicated to be out of stock is present at the primary location.\",\n \"Upon the visual inspection, the stocking associate may then enter information into the inventory management system 100 using the inventory management electronic device 120 to indicate whether the item 90 is or is not present at the primary location at the retail sales facility 110.If the inventory management electronic device 120 indicates (e.g., via a displayed message, beep, or spoken words as discussed above) to the stocking associate that the item 90 is present in the secondary location (step 445), the tracking process ends (step 450), enabling the stocking associate to physically check the secondary location in an attempt to find the item 90 and provide it to the customer.\",\n \"Alternatively, if the inventory management electronic device 120 indicates (e.g., via a displayed message, beep, or spoken words as discussed above) to the stocking associate that the item 90 is not present in the secondary location (step 455), the stocking associate may then operate the inventory management electronic device 120 to determine, as described above, whether the item 90 indicated to be out of stock is present in the back room or stock room 170 at the retail sales facility 110 (step 460).\",\n \"If the inventory management electronic device 120 indicates (e.g., via a displayed message, beep, or spoken words as discussed above) to the stocking associate that the item 90 is present in the stock room 170 (step 465), the tracking process ends (step 470), enabling the stocking associate to physically check the stock room 170 in an attempt to find the item 90 and provide it to the customer.\",\n \"Alternatively, if the inventory management electronic device 120 indicates (e.g., via a displayed message, beep, or spoken words as discussed above) to the stocking associate that the item 90 is not present in the stock room 170 (step 475), the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to track the location of the item 90 at the retail sales facility 110 using predetermined inventory management factors 480 associated with the retail sales facility 110, as shown in FIG.\",\n \"4.It will be appreciated that the ten inventory management factors depicted in FIG.\",\n \"4 are shown by way of example only, and the processor of the control circuit 210 of the inventory management electronic device 120 may be programmed to analyze any one or more of these inventory management factors (or additional inventory management factors) to determine a predicted location of an out of stock item 90 at the retail sales facility 110.It will appreciated that the tracking of the out of stock items 90 at the retail sales facility 110 may be performed without requiring any calculation or analysis by the processor of the control circuit 210 of the inventory management electronic device 120, and that the system 100 may be configured such that the tracking of the out of stock items 90 may be performed by an inventory management computing device remote to the retail sales facility 110 and in communication with the inventory management electronic device 120.In such embodiments, the tracking analysis of the out of stock item 90 may be performed by the inventory management computing device remote to the grocery location 110 (based on data stored in the inventory management database 140 or a remote inventory management database), and may be stored at the remote inventory management database or in the inventory management database 140 until a time when a user uses the electronic computing device 120 to request and retrieve the perceived location of the out of stock item 90 from the remote inventory management database or the inventory management database 140, as appropriate.\",\n \"With reference to FIG.\",\n \"4, the exemplary inventory management factors that may be used for the tracking of the out of stock items 90 are: (1) mis-rings; (2) shipping error; (3) sales floor quantity versus shelf cap; (4) change in on-hand inventory at the retail sales facility; (5) bin accuracy; (6) perpetual inventory accuracy; (7) modular integrity; (8) shrink; (9) replenishment method; and (10) pick completion.\",\n \"Each factor is discussed in more detail below.\",\n \"Factor 1, Mis-Rings, refers to the data stored in the inventory management database 140 indicating that a cashier at a cash register did not correctly scan an item 90 (or did not for some reason scan all of the items 90) during a sale or return of the item 90.In some embodiments, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to interpret a higher value of Mis-Rings at the retail sales facility 110 as representing a higher likelihood that the system-indicated location/status of the item 90 is incorrect, and that the item 90 may be out of stock and not present at the retail sales facility 110.Factor 2, Shipping Error, refers to the data stored in the inventory management database 140 indicating that the number of items 90 indicated in shipping slips or in the system inventory database as being shipped to the retail sales facility 110 was incorrect.\",\n \"For example, a shipping error may be generated when the system indicates that 1000 items 90 were shipped to the retail sales facility 110 when in fact it was determined that only 980 or 990 items 90 were shipped to the retail sales facility 110.In some embodiments, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to interpret a higher value of Shipping Error at the retail sales facility 110 as representing a higher likelihood that the system-indicated location/status of the item 90 is incorrect, and that the item 90 may be out of stock and not present at the retail sales facility 110.Factor 3, SF>SC (sales floor quantity greater than shelf cap), refers to the data stored in the inventory management database 140 indicating that the number of items 90 indicated to be on the sales floor 180 at the retail sales facility 110 is greater than the shelf space where the items 90 are typically stored.\",\n \"In some embodiments, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to interpret a higher number of SF>SC occurrences at the retail sales facility 110 as representing a higher likelihood that the system-indicated location of the item 90 as being out of stock is incorrect, and that the item 90 may be elsewhere on the sales floor 180 or in another area of the retail sales facility 110.Factor 4, OH Delta (on-hand change), refers to the data stored in the inventory management database 140 indicating a change in the total number of items 90 in stock (i.e., on-hand) at the retail sales facility 110.In some embodiments, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to interpret a higher OH Delta value as representing a higher likelihood that the system-indicated location of the item 90 as being on the sales floor 180 of the retail sales facility 110 is incorrect, and that the item 90 is may be out of stock at the retail sales facility 110.Factor 5, Bin Accuracy, refers to the data stored in the inventory management database 140 reflecting the accuracy of the systematic indication of the location of an item 90 by the stocking associates at the retail sales facility 110.For example, if the number of items 90 entered into the system as being present in a storage bin by a stocking associate corresponds to actual number of items 90 in the storage bin when physically checked, or when the system indicates that the item 90 is not present in a storage bin and the item 90 is actually not present in the storage bin when physically checked, the bin accuracy value would be high for the retail sales facility 110, and vice versa.\",\n \"In some embodiments, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to interpret a lower Bin Accuracy value as representing a higher likelihood that the system-indicated location and status of the item 90 at the retail sales facility 110 is incorrect and vice versa.\",\n \"Factor 6, PI Accuracy (or perpetual accuracy), refers to the data stored in the inventory management database 140 reflecting the accuracy of the inventory location designation by the stocking associates at the retail sales facility 110.This factor generally indicates whether the items 90 are generally located where the system indicates they are located.\",\n \"In some embodiments, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to interpret a lower PI Accuracy value as representing a higher likelihood that the system-indicated location and status of the item 90 at the retail sales facility 110 is incorrect and vice versa.\",\n \"Factor 7, Mod Integrity (or modular planogram integrity), refers to the data stored in the inventory management database 140 indicating how correctly the stocking associates at the retail sales facility 110 stock the shelf on the sales floor 180 with the items 90 and/or how correctly the shelf on the sales floor 180 is set up for the items 90.This factor generally indicates whether the actual layout of the items 90 on the sales floor of the retail sales facility 110 corresponds to the layout of the items 90 according to the inventory management system 10.In some embodiments, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to interpret a lower PI Accuracy value as representing a higher likelihood that the system-indicated location and status of the item 90 at the retail sales facility 110 is incorrect and vice versa.\",\n \"Factor 8, shrink, indicates how often items 90 go missing or unaccounted for at the retail sales facility 110 (e.g., as a result of theft, supplier mistakes, or other paperwork errors).\",\n \"In some embodiments, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to interpret a higher shrink value as representing a higher likelihood that the item 90 is not present at the retail sales facility 110 and vice versa.\",\n \"Factor 9, Replen Method (or replenishment method) indicates whether the item 90 moves quickly or slowly and is replenished quickly or slowly at the retail sales facility 110.The replenishment method may be indicated as a high velocity distribution center (HVDC) or a regional distribution center (RDC).\",\n \"If the replenishment method is indicated as HVDC, the item 90 is replenished quickly and has high turnover, while an RDC replenishment method is indicative of items 90 that have low turnover and move slowly.\",\n \"Accordingly, in some embodiments, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to interpret an HVDC replenishment method as generally indicating a higher likelihood that the system-indicated location or status of the item 90 at the retail sales facility 110 is incorrect, and to interpret the RDC replenishment method as generally indicating a higher likelihood that the system-indicated location or status of the item 90 at the retail sales facility 110 is correct.\",\n \"Factor 10, Pick Completion, indicates how often when the system indicates to an associate to pick an item 90 (e.g., from a storage bin) that the associate actually completes the pick.\",\n \"For instance, a low pick completion percentage may indicate that a stocking associate is not operating efficiently but likely honestly; an average pick completion may indicate that a stocking associate is operating within the norm of expected efficiency and honesty; a high pick completion may indicate that an associate may be entering into the system that the associate picked an item while the associate is not physically picking the item.\",\n \"Thus, in some embodiments, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to interpret a high pick completion percentage at the retail sales facility 110 as indicative of a higher likelihood that the system-indicated location or status of the item 90 at the retail sales facility 110 is incorrect.\",\n \"In the exemplary embodiment illustrated in FIG.\",\n \"4, in addition to the ten exemplary inventory management factors discussed above based on which a perceived location of the out of stock item 90 may be tracked at the retail sales facility 110, the processor of the control circuit 210 of the inventory management electronic device 120 may be programmed to track the location of the item 90 at the retail sales facility 110 using predetermined worker task events 490 associated with the product 90.It will be appreciated that the nine worker task events 490 depicted in FIG.\",\n \"4 are shown by way of example only, and any one or more of these worker task events 490 (or additional worker task events) may be analyzed by the processor of the control circuit 210 of the inventory management electronic device 120 to determine a perceived location of an out of stock item 90 at the retail sales facility 110.The exemplary worker task events are identified in FIG.\",\n \"4 by numbers that continue the numbering from the last inventory management factor and are as follows: (11) time stamp of last sale of the item 90 to a customer; (12) time stamp of last customer return of the item 90; (13) time stamp of last customer claim for the item 90 (i.e., product indicated as not sellable); (14) time stamp of last binning or unbinning of the item 90; (15) time stamp of last feature set or unset of the item 90 (i.e., product is displayed as a featured item on the sales floor 180); (16) time stamp of last delivery of the item 90; (17) time stamp of last scan of the item 90; (18 ) time stamp of last price change of the item 90; and (19) time stamp of pick of the item 90.In one embodiment, the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to track the location of the item 90 at the retail sales facility 110 using the inventory management factors 480 and the worker task events 490 described above and output a perceived location of the item 90 at the retail sales facility 110 based on the tracking analysis.\",\n \"Some exemplary output of the processor of the control circuit 210 of the inventory management electronic device 120 based on the above-discussed inventory management factors (F1, F2, F3, etc.)\",\n \"and worker task events (T11, T12, T13, etc.)\",\n \"are discussed below.\",\n \"It will be appreciated that output of the processor of the control circuit 210 of the inventory management electronic device 120 regarding the perceived location of an out of stock item 90 at the retail sales facility 110 may be based on many different combinations of one or more of the above-discussed inventory management factors 480 and/or worker task events 490, or may be based on combinations including additional inventory management factors 480 and additional worker task events 490 suitable for tracking a location of the out of stock item 90 at the retail sales facility 110.For example, the processor of the control circuit 210 of the inventory management electronic device 120 may be programmed to output that the item 90 is not present (i.e., out of stock) at the retail sales facility 110 if at least one of the following eight conditions is met during the tracking analysis: (1) if bin accuracy (F5) or perpetual accuracy (F6) or modular planogram integrity (F7) or pick completion percentage (F10) are low, and shrink (F8) or shipping error (F2) or mis-rings (F1) are high; (2) if time stamp of last delivery (T16) is newest and then the time stamp of last sale (T11) is newest, and on-hand delta (F4) is low; (3) if shrink (F8) is high; (4) if time stamp of last scan is newest (T17), and then timestamp of last sale is newest (T11), and then time stamp of last delivery (T16) is newest; (5) if the replenishment method (F9) is RDC assembly; (6) if on-hand delta (F4) is high and/or perpetual accuracy (F6) is low; (7) if time stamp of last price change newest (T18) and on-hand delta (F4) is high and/or perpetual accuracy (F6) is low; and (8) if the answer is “no” on all worker task events.\",\n \"Some other exemplary outputs of the control circuit 210 of the inventory management electronic device 120 and the inventory management factors 480 and worker task events 490 contributing to such outputs are described below.\",\n \"If SF>SC (F3) and time stamp of last delivery is newest (T16), and then time stamp of last pick is newest (T19), or

last scan is newest (T17), then the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to output an indication to a stocking associate to look for the item 90 in the unworked freight.\",\n \"If the replenishment method (F9) is determined to be HVDC, then the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to output an indication to a stocking associate to look for the item 90 in unbinned locations or previous binned area of the retail sales facility 110.If the time stamp of last claim is newest (T13), then the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to output an indication to a stocking associate to look for the item 90 in the claims area of the retail sales facility 110.If the time stamp of last return is newest (T12), then the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to output an indication to a stocking associate to look for the item 90 in the claims or returns area of the retail sales facility 110.If the time stamp of last pick is newest (T19) and

the item 90 in the pick carts in the stock room 170 of the retail sales facility 110.If modular planogram integrity (F7) is low, then the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to output an indication to a stocking associate to look for the item 90 in an area near the primary location on the sales floor 180 of the retail sales facility 110.If the time stamp of last pick is newest (T19) and pick completion (F10) or bin accuracy (F5) are low, then the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to output an indication to a stocking associate to look for the item 90 in the bin where the item 90 was indicated to be previously stored at the retail sales facility 110.If the time stamp of last bin or unbin is newest (T14) and pick completion (F10) or bin accuracy (F5) are low, then the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to output an indication to a stocking associate to look for the item 90 in the bin where the item 90 was indicated to be previously stored at the retail sales facility 110.If the time stamp of last feature set newest (T15), then the processor of the control circuit 210 of the inventory management electronic device 120 is programmed to output an indication to a stocking associate to look for the item 90 in feature locations on the sales floor 180 or unbinned in the stock room 170 of the retail sales facility 110.In one approach, the processor of the control circuit 210 of the inventory management device 120 is programmed to monitor whether one or more worker task events 490 entered into the inventory management database 140 as being completed was in fact physically completed.\",\n \"Based on this monitoring, the processor of the control circuit 210 of the inventory management device 120 is programmed to generate in the inventory management database

food intake by analyzing the content of foods and assisting the individuals to adjust their eating to comply with their respective diet plans.","The preferred embodiment provides a smart mobile phone application provided with facilities for individuals to upload a picture of a plate of food items or meals they are about to consume and receive a real-time or just-in-time modification to the meal generated by a nutritionist or an artificial intelligence (AI) program.","The modification is generated based on the individual's personalized profile parameters, personalized weight-loss goals and the meal to be consumed as well as the history of meals previously consumed.","Since the modification is generated at the point of consumption, the individual does not need to remember any dietary plans or guidelines or analyze any detailed information about the meal in order to make practical decisions about what to eat.","The individual uploads a picture of the meal, receives a real time modification and eats the meal according to the modification.","In the mobile application, individuals register as users and enter certain required profile parameters, and use the smart-phone camera to take photographs of meals and upload them to a secured database.","Authorized nutritionists, dieticians or professionals examine the uploaded photographs and related information and compose specific modifications to the meals based on the individuals' respective profile parameters and their personalized weight-loss goals.","The user receives a customized modification to the uploaded photograph by a qualified nutritionist.","This greatly simplifies the weight-loss regimen.","Nutritionists or dieticians edit or add pre-configured clarifying text, graphics, audio or video to the uploaded photographs in order to indicate the specific modifications.","This embodiment also envisions the use of artificial intelligence techniques to algorithmically select uploaded photographs, apply user-specific weight-loss rules, generate and compose suitable modifications for the associated users.","In cases where the photographs are not readable, the nutritionist or the artificial intelligence program marks them as exceptions and sets up a queue for further handling by more skilled human experts.","Once the modifications are composed, push notifications are automatically sent to the respective users to view the modifications.","The time of elapse of tracking for each photograph is monitored, and if it is elapsed beyond certain threshold limits delay notifications, tips and other information are automatically sent.","The mobile application also displays a timeline of past photographs, modifications and comments, so the user may scroll back and forth to examine them at any time, zoom in to a specific past photograph, indicate actual adherence to the modifications and rate their quality, timeliness and effectiveness.","The preferred embodiment also enables users to get answers to weight-loss or other health-related questions at any time by initiating a help request and directing it to a nutritionist or a dietician or other health professional, or an artificial intelligence program.","Also, the users to get assistance in dealing with food cravings at any time by initiating a craving help request to assigned helper or friend groups, who may respond and attempt to distract the requesting user.","A further provision aggregates, for a particular user, the nutritional values of the food ingested on a particular day, and suggest what items may be eaten at the end of the day to ensure that the user's specific daily dietary limits are not exceeded.","This also provides information regarding nearby restaurant menus or grocery store items in the vicinity of the user's current location and suggests consuming the food items available in the restaurant menus or grocery stores.","The present invention also provides a separate container or plate separator device for placing food items that are flagged as ‘do not eat at this meal’ or rejected as part of the nutritionist's modification, for ingestion by the user, a different person or animal, or for disposal, at a later time.","In addition to this, the present invention also provides a placemat printed with grey and white or color patterned squares of standard size to provide a sizing and color reference, as assistance for estimating the nature, size and/or quantity of food items on a plate that is placed on top of the placemat.","Referring now to FIG.","1a, illustrates a process flow for downloading and registering with the mobile phone application by an individual user.","An individual can locate and download the mobile application from play store or from a website and to activate the application by installing in the mobile phone [2].","The application prompts the individual to enter the mobile phone number and receives a verification code and sends an authentication code as one-time-password to the mobile phone number for verification.","The application then allows the user to enter the one-time-password [6].","The system verifies the entered code and permits the user for further data entry [8] that includes personalized profile parameters, personalized health goal, other health goals, personalized weight-loss goals, etc.","[10].","The user's personalized profile parameters include age, gender, body shape, current weight & height, target weight, blood pressure, cholesterol, blood sugar, etc.","The personalized health goals include target amount of weight to reduce, target amount of blood pressure or blood sugar to be attained, etc.","Further, the user then accepts the terms and conditions of the system to attain the assistance of the application and completes the registration [12].","The system stores the selected user data in the mobile phone application and in the secured server [14] with respective databases as secured server user database [16] and secured mobile app user database [18].","Where, the user can be a person or a parent or a caregiver or a pet-owner seeking real-time assistance.","FIG.","1b, illustrates the process flow for generation of user-specific ranked weight-loss rules based on user-profile parameters and other user data from the secured server database.","The system reads the user data and parameters [14] from the secured server user database [16].","These user personalized profile parameters and other parameters such as recent meal history serve as inputs to the algorithms for generating the user specific ranked weight-loss rules.","The ranked weight-loss rules also include meal modification rules that are generated by various algorithms for different health goals that are assigned based on the specific user's profile data and/or health goals.","The system generates the user specific ranked rules for weight-loss [20] and stores the generated rules in a database of user specific ranked rules for weight loss [22].","FIG.","2, illustrates the process flow for sending a meal-time reminder to the registered user by prompting the user to activate the mobile application.","The application runs a typical ‘Meal-Time Monitor’ routine [24] in the background that detects the occurrence of a ‘typical meal-time’, based on past history of meals and other relevant data entered by a registered user that is stored in the secured mobile application user database [18].","When an impending meal-time is detected, the application displays a Meal-Time Reminder as a notification [26] that is displayed on the mobile phone screen.","Simultaneously, the application also activates the camera and displays the camera icon for the user to capture a photograph of the next meal [28].","The users can also use 2D or a 3D camera affixed to their eyeglass or other means to capture photographs of the food item/meals to be consumed.","Further, the users are allowed to capture photographs of the food items at a grocery store to attain personalized instructions on their suitability, based on personalized health profile and other health goals.","The registered user can also capture and upload additional or sequential photographs representing additional servings at a particular meal.","The user captures multiple photographs of the meal [30], views them, and selects the best photograph with respect to clarity and uploads it [32] by clicking on the ‘upload’ button.","Before uploading, the user is allowed to add specific graphical modifications or text comments or audio comments or requests and/or other related information to the captured photographs.","These comments also include specific queries with respect to their weight-loss or health goals.","Further, means are provided for the registered users to add annotations by clicking or touching on the mobile phone screen on certain food items in the modified image to indicate respective food item names and to provide specific requests to the nutritionist.","Additionally, means are provided for the registered user to seek advice from the nutritionist or AI on what to eat for dessert at the end of the meal, given the meal that has just been consumed and receive a response; on what to eat for dinner at the end of the day, given all the meals that have been consumed thus far and receive a response and to seek advice on food item or recipe swaps to improve the quality of their nutritional intake.","FIG.","3, illustrates the process flow for storing the uploaded photographs in a secured database and queuing of the photographs to initiate further action.","After uploading the best photographs by the registered users, the uploaded photographs are received, identified, time-stamped &associated with other user data [34], and stored in a secured database of uploaded photographs.","All the data received from multiple users is stored in a secured database of meal photographs, time stamps and other user data [36].","The system then sorts the data using pre-defined criteria and generates an input queue of photographs and associated data for further action by nutritionists, dieticians and other professionals [38].","The System also generates an input queue of photographs for input to an Artificial Intelligence (AI) Program [40] and the further process is depicted in FIG.","4b.","The input queues are classified based on the specific text comments or requests attached to the uploaded photographs for assigning to a particular nutritionist or an AI.","This classification is attained by providing specific filters that include by user, by associated nutritionist, by artificial intelligence program or the like for assigning the uploaded photographs.","Additional filters are also provided based on meal modification rules or other criteria to further classify the input queues, thereby presenting an input queue of uploaded photographs to which same rules or criteria are to be applied.","FIG.","4a illustrates the process flow for nutritionists to access the system for providing modifications on the uploaded photographs of the food items.","Nutritionists log in to the system to view the input queues of uploaded photographs, compose and save meal modifications.","In the customary manner, nutritionists, dieticians or other authorized professionals log in to the system [44] after their authentication.","Further, the system displays sorted input queues of photographs and associated information based on their respective authorizations [46].","As new photographs are continuously uploaded by users, the system continuously refreshes the sorted input queues [48].","A particular nutritionist, dietician or professional with proper authorizations, who has accessed his or her respective sorted queue, views thumbnails of the uploaded photographs and associated data and selects a particular photograph [50].","The System then displays a larger version of the selected photograph along with the applicable Ranked Weight-loss Rules for the Particular User [60].","The rules are generated using the Database of User-Specific Diet Rules [62] and the Database of User-Specific Ranked Rules for Weight Loss [22] according to the present embodiment.","In other embodiments, the user-specific ranked rules may reflect other health objectives such as waist-reduction, heart-healthy, cancer-prevention, diabetes management, etc., or rules that enforce adherence to certain diets, e.g.","DASH (Dietary Approaches to Stop Hypertension) Diet, etc.","The Nutritionist analyzes the selected photograph and categorizes the food items in the meal [52].","The nutritionist then applies the user's respective weight-loss rules to compose specific Meal Modifications and Comments by using web-based applications or mobile phone applications or tablet-based applications, and saves those [54] to the Secured Output Queue [66].","The composed meal modifications and comments by the nutritionist include text based or graphic based comments or modifications on the photographs and also estimates of the nutritional attributes and their corresponding values of the food items or meals to be consumed or rejected by a user.","The text based comments include generic eating instructions, personalized eating instructions, pre-configured textual comments and textual indicators on the modifications to indicate the increase or decrease in the quantity of the food to be consumed.","The graphic based comments include free-form line drawings, visual effects for increasing/decreasing the appearance of the food items, pre-configured clarifying graphics, pre-configured graphical indicators to indicate the increase or decrease in the quantity of the food to be consumed, magnification/de-magnification of specific food items indicating consumption levels.","Means are provided for vocal comments and video comments to be attached.","These comments are stored in the secured database as a data set associated with a specific image or from a specific registered user.","All these Photographs, modifications and associated data are also stored in the Secured Database of Food Items, Values, Modifications and Rules as an archive [56].","If the nutritionist is unable to recognize or categorize the food items in any photograph, then the nutritionist generates an exception for that particular photograph [58].","The nutritionist makes suggestions to reduce one item or to increase other items to compensate for nutritional values based on the specific user goals.","Also, the nutritionist manually composes specific modifications to photographs based on the user's past meal history or user's specific dietary restrictions, profile parameters, personalized weight-loss goals or personalized diet plans.","In one embodiment, there exists a means on the mobile phone to view a suggested eating sequence for eating food items in the photograph which is automatically projected by the registered user by clicking on the said means include an icon or the like.","This suggested eating sequence can be an unconventional sequence projected as a numbered list.","The exception marked photographs [58] are reverted back to the respective registered user, thereby enabling the user to modify or add clarifying comments to that particular food item and re-upload the photograph.","In one embodiment, the nutritionist provides appropriate observations, or asks questions to a particular user depending on their diet; determines the consumable calories by a particular user based on the target amount of calories to be reduced, and determine the quantity of food items to be reduced/increased; uses pre-configured or free graphical/alphanumeric editing tools to indicate the food items to be modified and also sends encouraging or congratulatory comments when the plate of food needs no suggestions.","In all embodiments, the nutritionist may be a dietician or a veterinarian or other professional, providing assistance to individual adults, parents on behalf of children, adults on behalf of their parents, pet-owners and so on.","FIG.","4b illustrates the process flow for the AI Program to provide modifications on the uploaded photographs of the food items.","The automated programs using artificial intelligence (AI) techniques access input queues of uploaded photographs and associated data, select a photograph, access the associated data and user-specific weight-loss rules to generate and compose modifications and comments.","The AI program selects a photograph in the input queue [72] to apply known exception rules from the database Known Exception Rules Database [76] on the selected photograph [74].","If exception rules apply, the AI Program generates an exception immediately [82] and assigning an exception mark to that particular image if unrecognizable or

their food intake by analyzing the content of foods and assisting the individuals to adjust their eating to comply with their respective diet plans.\",\n \"The preferred embodiment provides a smart mobile phone application provided with facilities for individuals to upload a picture of a plate of food items or meals they are about to consume and receive a real-time or just-in-time modification to the meal generated by a nutritionist or an artificial intelligence (AI) program.\",\n \"The modification is generated based on the individual's personalized profile parameters, personalized weight-loss goals and the meal to be consumed as well as the history of meals previously consumed.\",\n \"Since the modification is generated at the point of consumption, the individual does not need to remember any dietary plans or guidelines or analyze any detailed information about the meal in order to make practical decisions about what to eat.\",\n \"The individual uploads a picture of the meal, receives a real time modification and eats the meal according to the modification.\",\n \"In the mobile application, individuals register as users and enter certain required profile parameters, and use the smart-phone camera to take photographs of meals and upload them to a secured database.\",\n \"Authorized nutritionists, dieticians or professionals examine the uploaded photographs and related information and compose specific modifications to the meals based on the individuals' respective profile parameters and their personalized weight-loss goals.\",\n \"The user receives a customized modification to the uploaded photograph by a qualified nutritionist.\",\n \"This greatly simplifies the weight-loss regimen.\",\n \"Nutritionists or dieticians edit or add pre-configured clarifying text, graphics, audio or video to the uploaded photographs in order to indicate the specific modifications.\",\n \"This embodiment also envisions the use of artificial intelligence techniques to algorithmically select uploaded photographs, apply user-specific weight-loss rules, generate and compose suitable modifications for the associated users.\",\n \"In cases where the photographs are not readable, the nutritionist or the artificial intelligence program marks them as exceptions and sets up a queue for further handling by more skilled human experts.\",\n \"Once the modifications are composed, push notifications are automatically sent to the respective users to view the modifications.\",\n \"The time of elapse of tracking for each photograph is monitored, and if it is elapsed beyond certain threshold limits delay notifications, tips and other information are automatically sent.\",\n \"The mobile application also displays a timeline of past photographs, modifications and comments, so the user may scroll back and forth to examine them at any time, zoom in to a specific past photograph, indicate actual adherence to the modifications and rate their quality, timeliness and effectiveness.\",\n \"The preferred embodiment also enables users to get answers to weight-loss or other health-related questions at any time by initiating a help request and directing it to a nutritionist or a dietician or other health professional, or an artificial intelligence program.\",\n \"Also, the users to get assistance in dealing with food cravings at any time by initiating a craving help request to assigned helper or friend groups, who may respond and attempt to distract the requesting user.\",\n \"A further provision aggregates, for a particular user, the nutritional values of the food ingested on a particular day, and suggest what items may be eaten at the end of the day to ensure that the user's specific daily dietary limits are not exceeded.\",\n \"This also provides information regarding nearby restaurant menus or grocery store items in the vicinity of the user's current location and suggests consuming the food items available in the restaurant menus or grocery stores.\",\n \"The present invention also provides a separate container or plate separator device for placing food items that are flagged as ‘do not eat at this meal’ or rejected as part of the nutritionist's modification, for ingestion by the user, a different person or animal, or for disposal, at a later time.\",\n \"In addition to this, the present invention also provides a placemat printed with grey and white or color patterned squares of standard size to provide a sizing and color reference, as assistance for estimating the nature, size and/or quantity of food items on a plate that is placed on top of the placemat.\",\n \"Referring now to FIG.\",\n \"1a, illustrates a process flow for downloading and registering with the mobile phone application by an

other relevant data entered by a registered user that is stored in the secured mobile application user database [18].\",\n \"When an impending meal-time is detected, the application displays a Meal-Time Reminder as a notification [26] that is displayed on the mobile phone screen.\",\n \"Simultaneously, the application also activates the camera and displays the camera icon for the user to capture a photograph of the next meal [28].\",\n \"The users can also use 2D or a 3D camera affixed to their eyeglass or other means to capture photographs of the food item/meals to be consumed.\",\n \"Further, the users are allowed to capture photographs of the food items at a grocery store to attain personalized instructions on their suitability, based on personalized health profile and other health goals.\",\n \"The registered user can also capture and upload additional or sequential photographs representing additional servings at a particular meal.\",\n \"The user captures multiple photographs of the meal [30], views them, and selects the best photograph with respect to clarity and uploads it [32] by clicking on the ‘upload’ button.\",\n \"Before uploading, the user is allowed to add specific graphical modifications or text comments or audio comments or requests and/or other related information to the captured photographs.\",\n \"These comments also include specific queries with respect to their weight-loss or health goals.\",\n \"Further, means are provided for the registered users to add annotations by clicking or touching on the mobile phone screen on certain food items in the modified image to indicate respective food item names and to provide specific requests to the nutritionist.\",\n \"Additionally, means are provided for the registered user to seek advice from the nutritionist or AI on what to eat for dessert at the end of the meal, given the meal that has just been consumed and receive a response; on what to eat for dinner at the end of the day, given all the meals that have been consumed thus far and receive a response and to seek advice on food item or recipe swaps to improve the quality of their nutritional intake.\",\n \"FIG.\",\n \"3, illustrates the process flow for storing the uploaded photographs in a secured database and queuing of the photographs to initiate further action.\",\n \"After uploading the best photographs by the registered users, the uploaded photographs are received, identified, time-stamped &associated with other user data [34], and stored in a secured database of uploaded photographs.\",\n \"All the data received from multiple users is stored in a secured database of meal photographs, time stamps and other user data [36].\",\n \"The system then sorts the data using pre-defined criteria and generates an input queue of photographs and associated data for further action by nutritionists, dieticians and other professionals [38].\",\n \"The System also generates an input queue of photographs for input to an Artificial Intelligence (AI) Program [40] and the further process is depicted in FIG.\",\n \"4b.\",\n \"The input queues are classified based on the specific text comments or requests attached to the uploaded photographs for assigning to a particular nutritionist or an AI.\",\n \"This classification is attained by providing specific filters that include by user, by associated nutritionist, by artificial intelligence program or the like for assigning the uploaded photographs.\",\n \"Additional filters are also provided based on meal modification rules or other criteria to further classify the input queues, thereby presenting an input queue of uploaded photographs to which same rules or criteria are to be applied.\",\n \"FIG.\",\n \"4a illustrates the process flow for nutritionists to access the system for providing modifications on the uploaded photographs of the food items.\",\n \"Nutritionists log in to the system to view the input queues of uploaded photographs, compose and save meal modifications.\",\n \"In the customary manner, nutritionists, dieticians or other authorized professionals log in to the system [44] after their authentication.\",\n \"Further, the system displays sorted input queues of photographs and associated information based on their respective authorizations [46].\",\n \"As new photographs are continuously uploaded by users, the system continuously refreshes the sorted input queues [48].\",\n \"A particular nutritionist, dietician or professional with proper authorizations, who has accessed his or her respective

pad stacks are described herein.","In the following description, numerous specific details are set forth, such as specific polishing pad and subpad compositions and designs, in order to provide a thorough understanding of embodiments of the present invention.","It will be apparent to one skilled in the art that embodiments of the present invention may be practiced without these specific details.","In other instances, well-known processing techniques, such as details concerning the combination of a slurry with a polishing pad to perform CMP of a semiconductor substrate, are not described in detail in order to not unnecessarily obscure embodiments of the present invention.","Furthermore, it is to be understood that the various embodiments shown in the figures are illustrative representations and are not necessarily drawn to scale.","Polishing pads for CMP operations may have trade-offs in performance such as a trade-off between across-wafer polishing uniformity versus within die polishing uniformity.","For example, hard polishing pads may exhibit good die-level planarization, but poor across-wafer uniformity.","A compressible subpad can be included with a polishing pad or layer to improve the global non-uniformity performance of the overlying polishing pad or layer.","In accordance with one or more embodiments herein, double coated subpads are described, such as double coated foam subpads.","For example, an adhesive coated foam can be used as a foundation (subpad) layer for CMP polishing pads.","The adhesive coated foam may be made using one or combination of the following features: (1) the adhesive may be directly coated onto one surface of the subpad material, (2) the adhesive can be directly coated onto both surfaces of the subpad material, (3) one adhesive can be a removable adhesive to enable application of a subpad/polishing layer pairing to a platen, and/or (4) one adhesive can be a permanent adhesive to promote strong bonding of the subpad to the back side of the polishing pad or layer.","To provide context, state of the art for subpad coupling to a polishing pad or layer involves use of a two-sided tape (such as a pressure sensitive adhesive, PSA, two-sided tape) to bond the subpad to the polishing pad.","A second two-sided tape is laminated to the side of the subpad that will ultimately be coupled to a platen of a CMP apparatus.","For example, fabrication of a polishing pad stack can involve laminating a PSA two-sided tape to both of the subpad faces.","FIG.","1 illustrates a cross-sectional view of a state of the art polishing pad and subpad pairing.","Referring to FIG.","1, a polishing pad 100 (top pad or polishing layer) is coupled to a subpad 102.The face of the subpad 102 proximate to the top pad 100 is coupled to the top pad 100 by a first PSA two-sided tape 104.The first PSA two-sided tape 104 may include a carrier film 104A (such as a polyethylene terephthalate, PET, film) which has a first permanent PSA layer 104B and a second permanent PSA layer 104C thereon.","The face of the subpad 102 distal from the top pad 100 has a second PSA two-sided tape 106 thereon.","The second PSA two-sided tape 106 may include a carrier film 106A (such as a PET film) which has a first permanent PSA layer 106B and a second permanent PSA layer 106C thereon.","The second PSA two-sided tape 106 may be further coupled to a third PSA two-sided tape 108.The third PSA two-sided tape 108 may include a carrier film 108A (such as a PET film) which has a first permanent PSA layer 108B and a second removable PSA layer 108C thereon.","The third PSA two-sided tape 108 may be suitable for removably coupling the top pad 100/subpad 102 polishing pad stack to a platen 110 of a CMP polishing apparatus, as is depicted in FIG.","1.There may be disadvantages associated with the type of polishing pad stack depicted in FIG.","1, as described below.","In contrast to the polishing pad stack of FIG.","1, FIG.","2 illustrates a cross-sectional view of a polishing pad and subpad pairing, in accordance with an embodiment of the present invention.","Referring to FIG.","2, a polishing pad stack for polishing a substrate includes a polishing pad 200 (top pad or polishing layer) coupled to a subpad 202, which may be a compressive subpad.","The polishing pad 200 has a polishing surface distal from the subpad 202, and a back surface proximate to the subpad 202.A first (upper) surface of the subpad 202 has a first pressure sensitive adhesive layer 204 coated thereon.","The upper surface of the subpad 202 is coupled directly to the back surface of the polishing pad 200 by the first pressure sensitive adhesive layer 204.Referring again to FIG.","2, in an embodiment, the polishing pad stack further includes a second pressure sensitive adhesive layer 206 coated on a second (lower) surface of the compressive subpad 202.In one such embodiment, the first pressure sensitive adhesive layer 204 is a permanent pressure sensitive adhesive layer for strong adhesion to the polishing pad 200.The second pressure sensitive adhesive layer 206 is a removable pressure sensitive adhesive layer and is for removably coupling the polishing pad stack to a platen 210 of a chemical mechanical polishing apparatus.","Although depicted in FIG.","2 as already coupled to a platen, in an embodiment, the polishing pad stack of FIG.","2 may include a release liner on the second pressure sensitive adhesive layer 206.Such a release liner may be used for transport and storage of a polishing pad stack, and may be removed to expose the second pressure sensitive adhesive layer 206 prior to coupling the polishing pad stack to a platen.","Advantages of the polishing pad stack of FIG.","2 over the polishing pad stack of FIG.","1 may be realized from the non-interrupted subpad construction achieved with the polishing pad stack type of FIG.","2.In particular, the number of interfaces is limited for adhesion failure.","Additionally, there may be less processing of the adhesive layers of the polishing pad stack of FIG.","2, as is described in greater detail below.","In an embodiment, direct coating of an adhesive onto a compressive subpad surface aids in sealing foam pores in the case of a compressive foam subpad.","Furthermore, the overall pad thickness may be reduced since there are no carrier films associated with the pressure sensitive adhesive layers, and the number of layers in the composite material is limited.","In an embodiment, direct adhesive coating offers superior adhesive anchorage to low surface energy foam that would otherwise be difficult when laminating a PSA two-sided tape to the surface of the subpad.","Finally, the number of manufacturing operations may be reduced from four to as low as one lamination operation (the lamination a coated subpad to a polishing pad), as is described in greater detail below.","Such a reduction in lamination operations and the achieved simplicity of construction of the polishing pad stack can result in potential reductions in manufacturing cost of the polishing pad stack.","Referring again to FIG.","2, a pressure sensitive adhesive layer, such as permanent pressure sensitive adhesive layer 204 or removable adhesive layer 206, requires only light to moderate pressure to adhere to a workpiece (such as light to

of the present invention.","Referring to FIG.","5, a polishing pad stack includes a polishing pad 500.The polishing pad includes a polishing layer 508 coupled to a foundation layer 502.As such, the back surface of the polishing pad 500 is a surface of the foundation layer 502.The front surface 504 of the foundation layer 502 is bonded to a surface polishing layer 508.In an embodiment, the

that is bonded with the foundation layer 502.In an embodiment, the foundation layer 502 is composed of a polycarbonate material, and the polishing surface layer 508 is a polyurethane material.","In a specific such embodiment, the polishing surface layer 508 is covalently bonded to the foundation layer 502.The term “covalently bonded” refers to arrangements where atoms from a first material (e.g., the material of a polishing surface layer) are cross-linked or share electrons with atoms from a second material (e.g., the material of a foundation layer) to effect actual chemical bonding.","Covalent bonding is distinguished from mechanical bonding, such as bonding through screws, nails, glues, or other adhesives.","In another specific embodiment, the polishing surface layer

the polishing pad stack to a platen.","As mentioned briefly above, polishing pad stacks including subpads such as those described herein may be fabricated using a reduced number of lamination processes than are otherwise used for state of the art pad stack fabrication.","As a comparative example, FIG.","6 illustrates a state of the art four step lamination pass pad/subpad fabrication process.","Referring to FIG.","6, a first lamination pass (Lamination Pass 1) involves lamination of a permanent PSA two-sided tape 602 on the back side of a polishing pad (top pad) 600.Excess of the permanent PSA two-sided tape is then trimmed off.","A second lamination pass (Lamination Pass 2) involves lamination of a subpad foam material 604 onto the permanent PSA two-sided tape 602 on the back up the polishing pad 600.Excess of the foam material is then trimmed off.","A third lamination pass (Lamination Pass 3) involves lamination of a second permanent PSA two-sided tape 606 onto the subpad

performed.","The resulting pad stack may be one such as described in association with FIG.","1.In contrast to the above described multi-lamination process, FIG.","7 illustrates a subpad fabrication process involving coating of pressure sensitive adhesive layers onto the subpad material, in accordance with an embodiment of the present invention.","Referring to FIG.","7, a subpad foam material 702 is used as a carrier film for a coating process.","The subpad foam material 702 is fed into application rollers 704 and 706 which apply a first pressure sensitive adhesive material 708 onto a first side 710 of the subpad foam material 702.A spreader bar or Meyer bar 712 is used to remove excess of and to evenly distribute the first pressure sensitive adhesive material 708 on the first side 710 of the subpad foam material 702.Referring again to FIG.","7, the subpad foam material 702 is then fed into application rollers 724 and 726 which apply a second pressure sensitive adhesive material 728 onto a second side 730 of the subpad foam material 702.A spreader bar or Meyer bar 732 is used to remove excess of and to evenly distribute the second pressure sensitive adhesive material 728 on the second side 730 of the subpad foam material 702.Referring again to FIG.","7, the doubly coated subpad foam material 702 is then directed to a dryer 740.The drying provides a foam material 702 having a first surface 710 with a first pressure sensitive adhesive layer 746 coated thereon, and having a second surface 730 with a second pressure sensitive adhesive layer 748 coated thereon.","Once transported through the dryer 740, further processing of the foam material 702 having the first 746 and second 748 pressure sensitive adhesive layers thereon may be performed, as described in greater detail below.","Referring generally to FIG.","7, in an embodiment, a method of fabricating a polishing pad stack for polishing a substrate involves coating a first pressure sensitive adhesive layer 708 on a first surface 710 of a compressive subpad material 702.The method also involves coating a second pressure sensitive adhesive layer 728 on a second, opposite, surface 730 of the compressive subpad material 702.In an embodiment, the first pressure sensitive adhesive layer 708 is a permanent pressure sensitive adhesive layer, and the second pressure sensitive adhesive layer 728 is a removable pressure sensitive adhesive layer.","In another embodiment, the first pressure sensitive adhesive layer 708 is a removable pressure sensitive adhesive layer, and the second pressure sensitive adhesive layer 728 is a permanent pressure sensitive adhesive layer.","In either case, in an embodiment, for the removable pressure sensitive adhesive layer, a primer is applied to the associated side of the subpad material for increasing the adhesion of the removable pressure sensitive adhesive layer to the subpad material but retaining removability for the platen side of the removable pressure sensitive adhesive layer.","In an embodiment, coating of either the first or second pressure sensitive adhesive layer involves dispensing and then spreading a solvent-based adhesive formulation on a surface of the compressive subpad material.","In one such embodiment, subsequent to dispensing and then spreading a first solvent-based adhesive formulation on a first surface of the compressive subpad material and dispensing and then spreading a second solvent-based adhesive formulation on a second surface of the compressive subpad material, the first and second solvent-based adhesive formulations are dried (e.g., through dryer 740) to remove substantially all solvent from the first and second solvent-based adhesive formulations.","In an embodiment, a pressure sensitive adhesive layer is applied as a solvent-based adhesive formulation on a surface of the compressive subpad material at a temperature less than approximately 50 degrees Celsius.","Subsequently, the solvent-based adhesive formulation is dried in an air dryer at a temperature less than approximately 50 degrees Celsius.","Thus, referring generally to FIG.","7, providing PSA layers on a subpad material involves coating an adhesive/solvent solution onto the subpad material which acts a carrier film or a support layer in the fabrication process.","The viscosity of the adhesive formulation determines the coating method.","The adhesive formulation can be applied as an adhesive material carried in a solvent.","An exemplary coating method is a Meyer Rod Coating approach.","FIG.","8 illustrates coating of a pressure sensitive adhesive layer onto a subpad material using a Meyer bar, in accordance with an embodiment of the present invention.","Referring to FIG.","8, an applicator roll 802 delivers an adhesive formulation 804 to the surface of a subpad material 806 being coated.","In an embodiment, the adhesive formulation 804 is applied at a temperature less than approximately 50 degrees Celsius and, preferably less than approximately 40 degrees Celsius, and most preferably at room temperature or approximately 20-25 degrees Celsius.","In an embodiment, the temperature of the adhesive formulation 804 at the time of application is less than approximately 50 degrees Celsius and, preferably less than approximately 40 degrees Celsius, and most preferably at room temperature or approximately 20-25 degrees Celsius.","The applicator roll 802 delivers an excess of material 804.The excess is removed by a Meyer rod or bar 808 (an expanded view of which is depicted in box 810 of FIG.","8, which shows the rod wrapped with wire).","The amount of adhesive removed depends on the wire wrapping.","There may be multiple rods in series to produce smooth accurate coating thicknesses with tolerance at +/−0.001 inch.","The coated subpad material film is then directed 812 to an air dryer for solvent evaporation.","In an embodiment, the subpad having the adhesive coated thereon enters the dryer approximately 2-4 minutes after the adhesive is coated on the subpad.","In an embodiment, the subpad is dried in the air dryer for approximately 20 minutes.","Referring again to FIG.","7, a release liner 790 is then applied to one of the coated adhesive layers at the end of the coating process.","In one embodiment, the release liner 790 is added to the removable pressure sensitive adhesive layer after the removable pressure sensitive adhesive layer has been coated on the subpad material.","In other embodiments, however, the removable pressure sensitive adhesive layer is coated on the subpad material by first applying the removable pressure sensitive adhesive material to the release liner and then delivering the removable pressure sensitive adhesive material to the subpad material.","In either case, such a release liner may be removed prior to coupling the removable pressure sensitive adhesive layer to a platen.","In an embodiment, although not depicted, a second release liner is added to the permanent pressure sensitive adhesive layer.","Such a second release liner may be included for transporting or storage of a coated subpad, but removed prior to adhering the coated subpad to a polishing pad via the permanent pressure sensitive adhesive layer of the coated subpad.","In other embodiments, however, a roll of the subpad material is formed without a release liner being included on the side of the subpad material having the permanent pressure sensitive adhesive layer thereon.","Whether or not the second release liner is included, a polishing pad may be adhered to the coated permanent pressure sensitive adhesive layer of the subpad material by a lamination process (thus leaving a single lamination process in place of the four described in association with FIG.","6).","The subpad material may then be cut around the shape of the polishing pad material.","As described herein, a release liner is a paper or plastic based carrier web material, which has a release agent on one or both sides of the release liner.","The release agent provides a release effect against any type of a sticky material such as an adhesive.","Release of the release liner involves separation of the release liner from the pressure sensitive adhesive layer.","With reference again to the process of FIG.","7, in an embodiment, the foam material (such as EVA or PE foam material) of the subpad is post processed prior to adhesive coating to achieve a tight gage tolerance of +/−1 mil throughout the web.","Typically, the material is buffed on one or both sides.","Such foams can vary in thickness from 15 mils up to 60 mils and may be produced in a wide range of densities ranging from a few pounds up to 60 pound foam.","Typical gage tolerance is +/10% of the total thickness, which can be as much as +/−6 mils or a total of 12 mils throughout the web.","It is to be appreciated that, as the semiconductor market technologies become more and more demanding to reduce line width, the consumable set used to manufacture these technologies must also meet tighter material property tolerances.","Post processing of a foam and subsequent direct adhesive coating can, in an embodiment, reduce the thickness tolerance and provide improved adhesive anchorage.","Such factors in turn affect the foam compressibility of the subpad material.","Compressibility is defined as (thickness under a load minus initial thickness)/initial thickness.","In some embodiment, the desired compressibility is low, e.g., typically less than 10%.","As described briefly in association with FIG.","7, a corona 792A and 792B or like treatment may be applied to one or both sides of a subpad material prior to adhesive layer coating.","It is to be appreciated that surface energy properties are an important consideration with industrial coatings.","The surface energy dictates if an applied coating will be accepted by the surface; this is known as wetting.","The definition of wetting is the ability of a liquid to maintain contact with a solid surface, resulting from intermolecular interactions when the two are brought together.","The degree of wetting (wettability) is determined by a force balance between adhesive and cohesive forces.","For adhesive coatings, the surface tension of the adhesive must be lower than the surface energy of the surface to which they are applied.","In the case of a material such as an EVA foam, the surface energy of the substrate must be raised to ensure sufficient wet out of the applied liquid (pressure sensitive adhesive coating).","There are number of methods for such surface treatment such as, but not limited to corona discharge, flame treatment, or plasma treatment.","Such treatments may be implemented to increase the surface energy of an EVA or PE foam from 30 dyne/cm up to, e.g., 40-42 dynes/cm.","In one such embodiment, a corona discharge treatment is applied to a compressive foam subpad material just prior to the adhesive coating process, as is shown in FIG.","7.FIG.","9 illustrates an apparatus for performing a Corona discharge treatment of a compressive foam subpad surface prior to coating an adhesive layer thereon, in accordance with an embodiment of the present invention.","Referring to FIG.","9, a subpad material layer 902 (e.g., compressive foam material layer) is rolled on a tamper roll 904 having a dielectric 906 thereon.","The arrangement provides an electrode 908 above the subpad material layer 902 with an air gap 910 between the electrode 908 and the subpad material layer 902.A corona generator power supply 912 is coupled to the electrode 908.The corona treatment is a surface modification technique that uses a low temperature corona discharge plasma to impart changes in the properties of a surface of the subpad material layer 902.In an embodiment, referring again to FIGS.","2 and 5, the polishing pad 200 or the polishing surface layer 508 is a homogeneous polishing pad or polishing surface layer.","In one such embodiment, the homogeneous polishing pad or polishing surface layer is composed of a thermoset polyurethane material.","For example, in a specific embodiment, the homogeneous polishing pad or polishing surface layer is composed of a thermoset, closed cell polyurethane material.","In an embodiment, the term “homogeneous” is used to indicate that the composition of a thermoset, closed cell polyurethane material is consistent throughout the entire composition of the body.","For example, in an embodiment, the term “homogeneous” excludes polishing pad bodies composed of, e.g., impregnated felt or a composition (composite) of multiple layers of differing material.","In an embodiment, the term “thermoset” is used to indicate a polymer material that irreversibly cures, e.g., the precursor to the material changes irreversibly into an infusible, insoluble polymer network by curing.","For example, in an embodiment, the term “thermoset” excludes polishing pads composed of, e.g., “thermoplast” materials or “thermoplastics”—those materials composed of a polymer that turns to a liquid when heated and returns to a very glassy state when cooled sufficiently.","It is noted that polishing pads made from thermoset materials are typically fabricated from lower molecular weight precursors reacting to form a polymer in a chemical reaction, while pads made from thermoplastic materials are typically fabricated by heating a pre-existing polymer to cause a phase change so that a polishing pad is formed in a physical process.","Polyurethane thermoset polymers may be selected for fabricating polishing pads described herein based on their stable thermal and mechanical properties, resistance to the chemical environment, and tendency for wear resistance.","The materials of polishing pad 200 or polishing surface layer 508 may be molded.","The term “molded” may be used to indicate that the polishing surface layer is formed in a formation mold.","In an embodiment, the molded polishing pad 200 or polishing surface layer 508, upon conditioning and/or polishing, has a polishing surface roughness approximately in the range of 1-5 microns root mean square.","In one embodiment, the molded polishing pad 200 or polishing surface layer 508, upon conditioning and/or polishing, has a polishing surface roughness of approximately 2.35 microns root mean square.","In an embodiment, the molded polishing pad 200 or polishing surface layer 508 has a storage modulus at 25 degrees Celsius approximately in the range of 30-500 megaPascals (MPa).","In another embodiment, the molded polishing pad 200 or polishing surface layer 508 has a storage modulus at 25 degrees Celsius approximately less than 30 megaPascals (MPa).","The materials of polishing pad 200 or polishing surface layer 508 may include pore-forming features.","In an embodiment, the polishing surface layer 108 or 208 has a pore density of closed cell pores approximately in the range of 6%-50% total void volume.","In one embodiment, the plurality of closed cell pores is a plurality of porogens.","For example, the term “porogen” may be used to indicate micro- or nano-scale spherical or somewhat spherical particles with “hollow” centers.","The hollow centers are not filled with solid material, but may rather include a gaseous or liquid core.","In one embodiment, the plurality of closed cell pores is composed of pre-expanded and gas-filled EXPANCEL™ distributed throughout (e.g., as an additional component in) a polishing surface layer of a polishing pad.","In a specific embodiment, the EXPANCEL™ is filled with pentane.","In an embodiment, each of the plurality of closed cell pores has a diameter approximately in the range of 10-100 microns.","In an embodiment, the plurality of closed cell pores includes pores that are discrete from one another.","This is in contrast to open cell pores which may be connected to one another through tunnels, such as the case for the pores in a common sponge.","In one embodiment, each of the closed cell pores includes a physical shell, such as a shell of a porogen, as described above.","In another embodiment, however, each of the closed cell pores does not include a physical shell.","In an embodiment, the plurality of closed cell pores is distributed essentially evenly throughout a thermoset polyurethane material of a homogeneous polishing pad or polishing surface layer.","In an embodiment, polishing pad 200 or polishing surface layer 508 is opaque.","In one embodiment, the term “opaque” is used to indicate a material that allows approximately 10% or less visible light to pass.","In one embodiment, the polishing pad 200 or polishing surface layer 508 is opaque in most part, or due entirely to, the inclusion of an opacifying particle filler, such as a lubricant, throughout (e.g., as an additional component in) the polishing pad 200 or polishing surface layer 508.In a specific embodiment, the opacifying particle filler is a material such as, but not limited to boron nitride, cerium fluoride, graphite, graphite fluoride, molybdenum sulfide, niobium sulfide, talc, tantalum sulfide, tungsten disulfide, or Teflon®.","In another aspect, the polishing pad 200 or polishing surface layer 508 may have a pattern suitable for polishing during a CMP operation.","In a first general example, some embodiments of the present invention include a plurality of protrusions having a pattern of linear features.","In a second general example, some embodiments of the present invention include a plurality of protrusions having a pattern of discrete curved features.","In a specific such example, discrete arc-shaped protrusions are included.","Other specific such embodiments include, but are not limited to, a plurality of partial circumferential protrusions disposed on a substantially circular polishing pad.","In a third general example, some embodiments of the present invention include a plurality of protrusions having a pattern of discrete tiles.","In a specific such embodiment, discrete hexagonal tile protrusions are included.","Other specific such embodiments include, but are not limited to, pluralities of circular tiles, oval tiles, square tiles, rectangular tiles, or a combination thereof.","Although the above three general examples are defined in terms of protrusions (e.g., the highest points of a patterned polishing surface layer), the polishing surface layers may also or alternatively be defined in terms of grooves (e.g., the lowest points of a patterned polishing surface layer).","Individual grooves may be from about 4 to about 100 mils deep at any given point on each groove.","In some embodiments, the grooves are about 10 to about 50 mils deep at any given point on each groove.","The grooves may be of uniform depth, variable depth, or any combinations thereof.","In some embodiments, the grooves are all of uniform depth.","For example, the grooves of a groove pattern may all have the same depth.","In some embodiments, some of the grooves of a groove pattern may have a certain uniform depth

embodiments, however, groove depth decreases with increasing distance from the center of the polishing pad.","In some embodiments, grooves of uniform depth alternate with grooves of variable depth.","Individual grooves may be from about 2 to about 100 mils wide at any given point on each groove.","In some embodiments, the grooves are about 15 to about 50 mils wide at any given point on

mils.","For a circular polishing pad, groove pitch is measured along the radius of the circular polishing pad.","The grooves may be of uniform pitch, variable pitch, or in any combinations thereof.","In some embodiments, the grooves are all of uniform pitch.","In some embodiments, however, groove pitch increases with increasing distance from the center of the polishing pad.","In some other embodiments, groove pitch decreases with increasing distance from the center of the polishing pad.","In some embodiments, the pitch of the grooves in one sector varies with increasing distance from the center of the polishing pad while the pitch of the grooves in an adjacent sector remains uniform.","In some embodiments, the pitch of the grooves in one sector increases with increasing distance from the center of the polishing pad while the pitch of the grooves in an adjacent sector increases at a different rate.","In some embodiments, the pitch of the grooves in one sector increases with increasing distance from the center of the polishing pad while the pitch of the grooves in an adjacent sector decreases with increasing distance from the center of the polishing pad.","In some embodiments, grooves of uniform pitch alternate with grooves of variable pitch.","In some embodiments, sectors of grooves of uniform pitch alternate with sectors of grooves of variable

pad stacks and methods of fabricating coated compressive subpads for polishing pad stacks are described herein.\",\n \"In the following description, numerous specific details are set forth, such as specific polishing pad and subpad compositions and designs, in order to provide a thorough understanding of embodiments of the present invention.\",\n \"It will be apparent to one skilled in the art that embodiments of the present invention may be practiced without these specific details.\",\n \"In other instances, well-known processing techniques, such as details concerning the combination of a slurry with a polishing pad to perform CMP of a semiconductor substrate, are not described in detail in order to not unnecessarily obscure embodiments of the present invention.\",\n \"Furthermore, it is to be understood that the various embodiments shown in the figures are illustrative representations and are not necessarily drawn to scale.\",\n \"Polishing pads for CMP operations may have trade-offs in performance such as a trade-off between across-wafer polishing uniformity versus within die polishing uniformity.\",\n \"For example, hard polishing pads may exhibit good die-level planarization, but poor across-wafer uniformity.\",\n \"A compressible subpad can be included with a polishing pad or layer to improve the global non-uniformity performance of the overlying polishing pad or layer.\",\n \"In accordance with one or more embodiments herein, double coated subpads are described, such as double coated foam subpads.\",\n \"For example, an adhesive coated foam can be used as a foundation (subpad) layer for CMP polishing pads.\",\n \"The adhesive coated foam may be made using one or combination of the following features: (1) the adhesive may be directly coated onto one surface of the subpad material, (2) the adhesive can be directly coated onto both surfaces of the subpad material, (3) one adhesive can be a removable adhesive to enable application of a subpad/polishing layer pairing to a platen, and/or (4) one adhesive can be a permanent adhesive to promote strong bonding of the subpad to the back side of the polishing pad or layer.\",\n \"To provide context, state of the art for subpad coupling to a polishing pad or layer involves use of a two-sided tape (such as a pressure sensitive adhesive, PSA, two-sided tape) to bond the subpad to the polishing pad.\",\n \"A second two-sided tape is laminated to the side of the subpad that will ultimately be coupled to a platen of a CMP apparatus.\",\n \"For example, fabrication of a polishing pad stack can involve laminating a PSA two-sided tape to both of the subpad faces.\",\n \"FIG.\",\n \"1 illustrates a cross-sectional view of a state of the art polishing pad and subpad pairing.\",\n \"Referring to FIG.\",\n \"1, a polishing pad 100 (top pad or polishing layer) is coupled to a subpad 102.The face of the subpad 102 proximate to the top pad 100 is coupled to the top pad 100 by a first PSA two-sided tape 104.The first PSA two-sided tape 104 may include a carrier film 104A (such as a polyethylene terephthalate, PET, film) which has a first permanent PSA layer 104B and a second permanent PSA layer 104C thereon.\",\n \"The face of the subpad 102 distal from the top pad 100 has a second PSA two-sided tape 106 thereon.\",\n \"The second PSA two-sided tape 106 may include a carrier film 106A (such as a PET film) which has a first permanent PSA layer 106B and a second permanent PSA layer 106C thereon.\",\n \"The second PSA two-sided tape 106 may be further coupled to a third PSA two-sided tape 108.The third PSA two-sided tape 108 may include a carrier film 108A (such as a PET film) which has a first permanent PSA layer 108B and a second removable PSA layer 108C thereon.\",\n \"The third PSA two-sided tape 108 may be suitable for removably coupling the top pad 100/subpad 102 polishing pad stack to a platen 110 of a CMP polishing apparatus, as is depicted in FIG.\",\n \"1.There may be disadvantages associated with the type of polishing pad stack depicted in FIG.\",\n \"1, as described below.\",\n \"In contrast to the polishing pad stack of FIG.\",\n \"1, FIG.\",\n \"2 illustrates a cross-sectional view of a polishing pad and subpad pairing, in accordance with an embodiment of the present invention.\",\n \"Referring to FIG.\",\n \"2, a polishing pad stack for polishing a substrate includes a polishing pad 200 (top pad or polishing layer) coupled to a subpad 202, which may be a compressive subpad.\",\n \"The polishing pad 200 has a polishing surface distal from the subpad 202, and a back surface proximate to the subpad 202.A first (upper) surface of the subpad 202 has a first pressure sensitive adhesive layer 204 coated thereon.\",\n \"The upper surface of the subpad 202 is coupled directly to the back surface of the polishing pad 200 by the first pressure sensitive adhesive layer 204.Referring again to FIG.\",\n \"2, in an embodiment, the polishing pad stack further includes a second pressure sensitive adhesive layer 206 coated on a second (lower) surface of the compressive subpad 202.In one such embodiment, the first pressure sensitive adhesive layer 204 is a permanent pressure sensitive adhesive layer for strong adhesion to the polishing pad 200.The second pressure sensitive adhesive layer 206 is a removable pressure sensitive adhesive layer and is for removably coupling the polishing pad stack to a platen 210 of a chemical mechanical polishing apparatus.\",\n \"Although depicted in FIG.\",\n \"2 as already coupled to a platen, in an embodiment, the polishing pad stack of FIG.\",\n \"2 may include a release liner on the second pressure sensitive adhesive layer 206.Such a release liner may be used for transport and storage of a polishing pad stack, and may be removed to expose the second pressure sensitive adhesive layer 206 prior to coupling the polishing pad stack to a platen.\",\n \"Advantages of the polishing pad stack of FIG.\",\n \"2 over the polishing pad stack of FIG.\",\n \"1 may be realized from the non-interrupted subpad construction achieved with the polishing pad stack type of FIG.\",\n \"2.In particular, the number of interfaces is limited for adhesion failure.\",\n \"Additionally, there may be less processing of the adhesive layers of the polishing pad stack of FIG.\",\n \"2, as is described in greater detail below.\",\n \"In an embodiment, direct coating of an adhesive onto a compressive subpad surface aids in sealing foam pores in the case of a compressive foam subpad.\",\n \"Furthermore, the overall pad thickness may be reduced since there are no carrier films associated with the pressure sensitive adhesive layers, and the number of layers in the composite material is limited.\",\n \"In an embodiment, direct adhesive coating offers superior adhesive anchorage to low surface energy foam that would otherwise be difficult when laminating a PSA two-sided tape to the surface of the subpad.\",\n \"Finally, the number of manufacturing operations may be reduced from four to as low as one lamination operation (the lamination a coated subpad to a polishing pad), as is described in greater detail below.\",\n \"Such a reduction in lamination operations and the achieved simplicity of construction of the polishing pad stack can result in potential reductions in manufacturing cost of the polishing pad stack.\",\n \"Referring again to FIG.\",\n \"2, a pressure sensitive adhesive layer, such as permanent pressure sensitive adhesive layer 204 or removable adhesive layer 206, requires only light to moderate pressure to adhere to a workpiece (such as light to moderate pressure to adhere a subpad 202 having a pressure sensitive adhesive layer coated thereon to a polishing pad 200).\",\n \"A pressure sensitive adhesive layer is not a glue layer which would otherwise require some level of curing.\",\n \"A pressure sensitive adhesive layer is also not a hot melt layer which otherwise requires heat for the adhesion to a workpiece.\",\n \"A pressure sensitive adhesive layer, as defined herein, also does not require the addition of water to activate the adhesion to a workpiece.\",\n \"Referring again to FIG.\",\n \"2, in an embodiment, the permanent pressure sensitive adhesive layer 204 has a peel strength of greater than approximately 4.5 pounds per inch at 25 degrees Celsius.\",\n \"The removable pressure sensitive adhesive layer 206 has a peel strength of less than approximately 4 pounds per inch at 25 degrees Celsius.\",\n \"In a particular embodiment, the removable pressure sensitive adhesive layer 206 has a peel strength of less than approximately 2.5 pounds per inch at 25 degrees Celsius.\",\n \"As used herein, peel strength is defined as strength at maximum adhesion of the pressure sensitive layer, where the test method use is defined in ASTM D3330.In an embodiment, the permanent pressure sensitive

subpad (i.e., the surface that is coupled to a polishing pad or the surface for coupling to a platen) has a surface energy approximately in the range of 30-40 dyne/cm2 (as measured prior to any post processing such as a Corona treatment).\",\n \"In an embodiment, the compressive subpad has a thickness approximately in the range of 10 mils to 40 mils.\",\n \"FIGS.\",\n \"3A and 3B are cross-sectional scanning electron microscope (SEM) images of exemplary compressive foam subpads, in accordance with an embodiment of the present invention.\",\n \"Referring to SEM image 300A of FIG.\",\n \"3A, a closed cell ethyl vinyl acetate (EVA) foam subpad is shown magnified at 100× magnification.\",\n \"Referring to SEM image 300B of FIG.\",\n \"3B, a closed cell polyethylene (PE) foam subpad is shown magnified at 100× magnification.\",\n \"Referring again to FIGS.\",\n \"3A and 3B, in an embodiment, the subpad foam layer is an EVA foam or polyethylene foam having low surface energy, typically 30-35 dyne/cm2.The surface energy is typically measured with an Accu Dyne pen that applies a simple solution using ASTM standard Test Method D 2578.The most common solution used includes ethyl cellosolve, formamide and a dye to make it easier to detect with the naked eye.\",\n \"The variation in concentration of the ethyl cellosolve % vs. the formamide % results in different dyne level solutions with each pen.\",\n \"Referring again to FIG.\",\n \"2, the permanent pressure sensitive adhesive layer 204 is coated on the surface of the subpad 202 proximate to the polishing pad 200.The removable pressure sensitive adhesive layer 206 is coated on the surface of the subpad 202 distal to the polishing pad 200.Use of the term “coated” is used to distinguish embodiments of the present invention from situations where a PSA such as a PSA two-sided tape is laminated on the surface of a subpad for ultimate coupling of the subpad to a polishing pad or to a platen (depending on the side of the subpad having the PSA laminated thereon).\",\n \"The term “coated” is also used to distinguish embodiments of the present invention from situations where a PSA such as a PSA two-sided tape is first laminated on the back surface of a polishing pad and subsequently used to adhere the polishing pad to the subpad through another lamination process.\",\n \"By contrast, in

spreading process.\",\n \"The coated layer is then dried to remove any carrier solvents used to apply the adhesive material on the surface of the subpad.\",\n \"The dried layer coated on a subpad surface is the pressure sensitive adhesive layer (either permanent or removable, depending on which side of the subpad is referenced).\",\n \"As an exemplary advantage of a coated adhesive layer as

adhesive formulation on a surface of the compressive subpad material at a temperature less than approximately 50 degrees Celsius.\",\n \"Subsequently, the solvent-based adhesive formulation is dried in an air dryer at a temperature less than approximately 50 degrees Celsius.\",\n \"Thus, referring generally to FIG.\",\n \"7, providing PSA layers on a subpad material involves coating an adhesive/solvent solution onto the subpad material which acts a carrier film or a support layer in the fabrication process.\",\n \"The viscosity of the adhesive formulation determines the coating method.\",\n \"The adhesive formulation can be applied as an adhesive material carried in a solvent.\",\n \"An exemplary coating method is a Meyer Rod Coating approach.\",\n \"FIG.\",\n \"8 illustrates coating of a pressure sensitive adhesive layer onto a subpad material using a Meyer bar, in accordance with an embodiment of the present invention.\",\n \"Referring to FIG.\",\n \"8, an

rods in series to produce smooth accurate coating thicknesses with tolerance at +/−0.001 inch.\",\n \"The coated subpad material film is then directed 812 to an air dryer for solvent evaporation.\",\n \"In an embodiment, the subpad having the adhesive coated thereon enters the dryer approximately 2-4 minutes after the adhesive is coated on the subpad.\",\n \"In an embodiment, the subpad is dried in the air dryer for approximately 20 minutes.\",\n \"Referring again to FIG.\",\n \"7, a release liner 790 is then applied to one of the coated adhesive layers at the end of the coating process.\",\n \"In one embodiment, the release liner 790 is added to the removable pressure sensitive adhesive layer after the removable pressure sensitive adhesive layer has been coated on the subpad material.\",\n \"In other embodiments, however, the removable pressure sensitive adhesive layer is coated on the subpad material by first applying the removable pressure sensitive adhesive material to the release liner and then delivering the removable pressure sensitive adhesive material to the subpad material.\",\n \"In either case, such a release liner may be removed prior to coupling the removable pressure sensitive adhesive layer to a platen.\",\n \"In an embodiment, although not depicted, a second release liner is added to the permanent pressure sensitive adhesive layer.\",\n \"Such a second release liner may be included for transporting or storage of a coated subpad, but removed prior to adhering the coated subpad to a polishing pad via the permanent pressure sensitive adhesive layer of the coated subpad.\",\n \"In other embodiments, however, a roll of the subpad material is formed without a release liner being included on the side of the subpad material having the permanent pressure sensitive adhesive layer thereon.\",\n \"Whether or not the second release liner is included, a polishing pad may be adhered to the coated permanent pressure sensitive adhesive layer of the subpad material by a lamination process (thus leaving a single lamination process in place of the four described in association with FIG.\",\n \"6).\",\n \"The subpad material may then be cut around the shape of the polishing pad material.\",\n \"As described herein, a release liner is a paper or plastic based carrier web material, which has a release agent on one or both sides of the release liner.\",\n \"The release agent provides a release effect against any type of a sticky material such as an adhesive.\",\n \"Release of the release liner involves separation of the release liner from the pressure sensitive adhesive layer.\",\n \"With reference again to the process of FIG.\",\n \"7, in an embodiment, the foam material (such as EVA or PE foam material) of the subpad is post processed prior to adhesive coating to achieve a tight gage tolerance of +/−1 mil throughout the web.\",\n \"Typically, the material is buffed on one or both sides.\",\n \"Such foams can vary in thickness from 15 mils up to 60 mils and may be produced in a wide range of densities ranging from a few pounds up to 60 pound foam.\",\n \"Typical gage tolerance is +/10% of the total thickness, which can be as much as +/−6 mils or a total of 12 mils throughout the web.\",\n \"It is to be appreciated that, as the semiconductor market technologies become more and more demanding to reduce line width, the consumable set used to manufacture these technologies must also meet tighter material property tolerances.\",\n \"Post processing of a foam and subsequent direct adhesive coating can, in an embodiment, reduce the thickness tolerance and provide improved adhesive anchorage.\",\n \"Such factors in turn affect the foam compressibility of the subpad material.\",\n \"Compressibility is defined as (thickness under a load minus initial thickness)/initial thickness.\",\n \"In some embodiment, the desired compressibility is low, e.g., typically less than 10%.\",\n \"As described briefly in association with FIG.\",\n \"7, a corona 792A and 792B or like treatment may be applied to one or both sides of a subpad material prior to adhesive layer coating.\",\n \"It is to be appreciated that surface energy properties are an important consideration with industrial coatings.\",\n \"The surface energy dictates if an applied coating will be accepted by the surface; this is known as wetting.\",\n \"The definition of wetting is the ability of a liquid to maintain contact with a solid surface, resulting from intermolecular interactions when the two are brought together.\",\n \"The degree of wetting (wettability) is determined by a force balance between adhesive and cohesive forces.\",\n \"For adhesive coatings, the surface tension of the adhesive must be lower than the surface energy of the surface to which they are applied.\",\n \"In the case of a material such as an EVA foam, the surface energy of the substrate must be raised to ensure sufficient wet out of the applied liquid (pressure sensitive adhesive coating).\",\n \"There are number of methods for such surface treatment such as, but not limited to corona discharge, flame treatment, or plasma treatment.\",\n \"Such treatments may be implemented to increase the surface energy of an EVA or PE foam from 30 dyne/cm up to, e.g., 40-42 dynes/cm.\",\n \"In one such embodiment, a corona discharge treatment is applied to a compressive foam subpad material just prior to the adhesive coating process, as is shown in FIG.\",\n \"7.FIG.\",\n \"9 illustrates an apparatus for performing a Corona discharge treatment of a compressive foam subpad surface prior to coating an adhesive layer thereon, in accordance with an embodiment of the present invention.\",\n \"Referring to FIG.\",\n \"9, a subpad

materials or “thermoplastics”—those materials composed of a polymer that turns to a liquid when heated and returns to a very glassy state when cooled sufficiently.\",\n \"It is noted that polishing pads made from thermoset materials are typically fabricated from lower molecular weight precursors reacting to form a polymer in a chemical reaction, while pads made from thermoplastic materials are typically fabricated by heating a pre-existing polymer to cause a phase change so that a polishing pad is formed in a physical process.\",\n \"Polyurethane thermoset polymers may be selected for

garden fountain 10 includes a base 12, a lower or reservoir bowl 24, a middle bowl 26 and an upper or planter bowl 28.The base 12 can be made up of one or more parts and is shown in the present example having a footing 14, a central shaft 16 and a bowl support 18.A power button 20 can be disposed in any suitable location and is shown here integrated into the bowl support 18.A battery compartment 22 is preferably disposed in the base of the central shaft 16, or the footing 14 (if of suitable size) The connection of the lower bowl to the footing can be achieved in any suitable known manner.","For example, a slot and groove mechanical engagement where the parts are fitted together and rotated to secure the connection could be used.","Such slot and groove configuration could also be used to connect the middle bowl 26 to the lower bowl 24.O-rings or other water sealing means can be used in any relevant application for the connection of the various parts of the fountain.","In addition, those of skill in the art will appreciated that each of the parts of the garden fountain 10 can be made of any suitable known material, which may include, but is not limited to, molded plastics.","FIGS.","2A and 2B show the battery compartment 22 having a battery 30 contained therein.","In this preferred implementation the battery is rechargeable and the battery compartment is preferably sealed from water such that the user may easily access the same without any concerns relating to the water contained within the lower and middle bowls.","Ideally, the battery compartment should have at least one opening to the outside air so as to prevent the formation of condensation in the compartment and thereby any negative effects to the battery as a result of the same.","Those of skill in the art will appreciate that the access panel for the battery compartment can be configured in any suitable manner, such as for example, a sliding panel, a hinged panel, and may also include a locking mechanism.","In one implementation, the rechargeable battery or batteries 30 can be recharged using a solar system (not shown), and/or using household electric power.","Alternatively, the batteries can be made to be disposable.","In addition to rechargeable power means, timing system 31 can be implemented where individual buttons are preset for predetermined time periods, or adjustable timing means are implemented.","In other implementations, the power source for the fountain can be solar powered, A/C powered using 110 v, 210 v and/or DC powered using a 12 v battery.","It is further contemplated that the garden fountain system may include a lighting system that provides accent lighting the fountain and/or the plant in the upper bowl planter.","The positioning of the lights cans be within or out of the water.","FIGS.","3 and 5 illustrate one example of the disposition of the pump 32 within the shaft 23 positioned within the lower/reservoir bowl 24 and configured to support the middle bowl 26.The pump 32 includes a power connection 34 which is connected to the battery 30 positioned in the base 16.The pump 32 sits in the bottom of the shaft 23 and is configured to draw water from the lower/reservoir bowl 24 and the pump feeds the same to the middle bowl 26 via a tube 36 connected to a water input connection 40 in the center of the middle bowl 26.Referring to FIGS.","3 and 4, the upper bowl 28, positioned siting within the middle bowl 26.In a preferred implementation, the upper bowl 28 is configured as planter.","As shown in FIG.","5, the upper bowl 28 includes a number of openings 42 at the bottom thereof.","The openings 42 allow the transfer of water from a middle bowl 26, into upper bowl 28 when the water level rises in bowl 26 to a predetermined level.","Bowl 26 has water introduced via a pump 32, (FIG.","3), drawing water from bottom of a lower bowl 24, (i.e., a reservoir bowl).","As shown in FIG.","3, the pump can be located in the lower reservoir bowl 24, and as shown in the present example, the pump 32 is positioned within the shaft supporting the middle bowl 26.Those of skill in the art will appreciate that any suitable known type of pump 32 with an appropriate water intake can be used.","According to one implementation, the pump 32 uses a 6-volt dc pump powered by the rechargeable battery 30 located in the base of the fountain.","When the pump is turned on, the water is pumped from lower bowl 24 into the middle bowl 26.The water continues to rise until the water level reaches the pour spouts 25 of middle bowl 26, at which point the water level 5 reaches its maximum height or level in middle bowl 26 and the water pours over back into lower bowl 24.","(See FIG.","5) As shown above, upper bowl 28 sits in middle bowl 26.The distance between the base of middle bowl 26 and base of bowl 28, specifically the water inlets 42 of upper bowl 28 are crucial to the operation.","The height of the water level in middle bowl 26 reaches at least to the bottom of the water inlets of upper bowl 28.Discs or spaces 43 can be added or subtracted to achieve the desired position of the base of the upper bowl 28 within the middle bowl 26.As will be evident from the above, height of the upper bowl 26 can be infinitely adjusted using the discs 43 depending on the water level desired/required for the plant in the upper bowl 28.According to one preferred implementation, a minimum height must at least reach the bottom of the water inlets 42 in upper bowl 28 in order for the soil 29 located in upper bowl 28 to be able to draw or wick the water up from middle bowl 26.Although shown in the form of openings, water inlets 42 can include a porous material 41 of any kind so as to prevent any soil from being undesirably being dispelled from the upper bowl 28 into middle bowl 26.As mentioned above, the height of upper bowl 28 in relation to middle bowl 26 will be adjustable.","The purpose of an adjustable height is such that you can raise or lower the water level in upper bowl 28.This is beneficial since plants require different amounts of water for growing.","In the current configuration one or more spacers 43 are used in between upper bowl 28 and middle bowl 26.Any number of or no spacers can be used.","In the configuration of FIG.","4, three (3) spacers 43 are shown.","This gives a total of four (4) water level settings.","The thickness of the spacers 43 can also be changed to accommodate other spacing options.","In one preferred implementation, no spacer present allows upper bowl 28 to sit at its lowest possible setting, providing the highest water level in upper bowl 28.As you add a spacer between the upper bowl 28 and middle bowl 26, bowl 28 will increase in height over middle bowl 26 thus raising upper bowl 28 proportionally higher above middle bowl 26 lowering the water level or line in upper bowl 28.As you add another spacer, this water level will continue to lower in bowl 28 until you can add spacer so that upper bowl 28 water inlets 42 can be completely above the water level in middle bowl 26.The above description is referring to the water level in the active or pump on mode.","This is when the water level is at its highest, but at no time does the water level rise above the maximum level provided by the waterspouts 25 in middle bowl 26.When in the active mode, or pump on mode and the maximum spacer 43 or height of upper bowl 28 is in use, the water level is raised in middle bowl 26 to the maximum height determined by the waterspouts 25.Upper bowl 28 being in its highest setting will only, when in active mode, have water coming in contact with the water inlets 42 in upper bowl.","When the fountain is inactive, pump off, the water level will lower to a point just below the maximum water level in middle bowl 26.At this point the water level is lower than the bottom of the water inlets 42 in upper bowl 28.This then provides an air gap necessary for healthy plant growth allowing the soil to aerate, from the bottom up.","In this same setting, when the fountain is in active mode, the water level in middle bowl 26 will rise to the maximum height provided by waterspouts 25 in bowl number 26.At such point, the water level will rise to allow the water inlets 42 in upper bowl 28 to come into contact with the water 5 in middle bowl 26.The resulting wicking effect allows the soil 29 in upper bowl 28 to wick the water up into bowl 28, providing water for the plant.","The water level in upper bowl 28 can be adjusted through raising and lowering the bowl in relation to middle bowl 26 with any number of methods, fixed and mechanical.","In addition, the water level in upper bowl 28 can be affected or adjusted to provide the proper amount of water to the plant in upper bowl 28 depending on if the fountain is active or inactive.","The above description relates to the adjusting of the water level in upper bowl 28 in the active mode.","If you adjust for the inactive mode, upper bowl 28 can be moved to, for example, the lowest setting.","This position will place the water inlets 42 of upper bowl 28 to below the maximum water level of middle bowl 26.If the fountain is first active and thus raising the water level in bowl 26 to the maximum level and then turned inactive, the water level will lower slightly to just below the spout level 25.However, upper bowl 28 water inlets 42 can be set so that they are lower than middle bowl 28's maximum level.","Therefore, the soil 29 in bowl 28 would continue to wick water up into bowl 28, even in the inactive mode.","This provides additional water for different type of plants or weather conditions.","This allows middle bowl 26 to act as a reservoir for upper bowl 28 until such time that the soil 29 in bowl 28 has wicked up the maximum amount of water it is capable of and or water has evaporated out of middle bowl 26.When either occurs, this will then lower the water level in middle bowl 26 to below the water inlets 42 in upper bowl 28, thus providing the necessary air gap 12 between upper bowl 28 and middle bowl number 26 to provide healthy conditions for good plant growth.","The shape of the bottom of upper bowl 28 and the bottom of middle bowl 26 is also critical for proper water flow.","Although there are numerous ways to introduce water into middle bowl 26, this description is for the current example being shown.","The outlet of a water distribution tube 40 coming from the pump 32 located, for example, in lower bowl number 24, in a preferred embodiment needs to be just slightly higher than the maximum water level provided by the waterspouts 25 in middle bowl 26.This prevents the water from middle bowl 26 from siphoning back into lower bowl 24, thus maintaining the inactive water level in middle bowl 26 once initially filled to maximum water level when active.","However, should the water siphon back into bowl 24, this can also be a benefit.","In the current embodiment, there is a fill chamber 46 located in the bottom of upper bowl 28, which is female in shape, which matches to the male water distribution pipe 40 in middle bowl 26.This allows the water distribution pipe 40 or tube to be higher than the maximum water level in middle bowl 26 while allowing the water inlet ports 42, located in the corresponding female shape of the bottom of upper bowl 28 to operate below the maximum water level in middle bowl 26.In a preferred embodiment, water is only introduced into upper bowl 28 through the water inlet ports 42.This allows for a non-pressurized or turbulent water introduction into the soil.","If the water from the distribution port in middle bowl 26 was directed straight directly into the soil 29 in upper bowl 28, it would erode the soil and causing excess soil to be introduced into the water system and erode the soil exposing the roots in the plant located in upper bowl 28.Although this system could have the water distributed to upper bowl 28 on in various manners, direct port from bowl number two into bowl number one.","Another is a water distribution pipe pouring water into the top of bowl 28 from bowl 24.The preferred embodiment is to wick the water from the bottom up from bowl number 26 into upper bowl 28 initially when in the active mode then also in the inactive mode as described above.","In the preferred embodiment, it has been found that the water distribution chamber 46 located in upper bowl 28, in relation to the air channels at the bottom of bowl 28, in relation to the water distribution port in middle bowl 26 can create a siphon effect after the fountain is inactive, thus siphoning all the water out of middle bowl 26 into lower bowl 24.This can be considered a positive effect if for example the plant in upper bowl 28 requires less water.","To reduce this effect if a small hole 48 is introduced into the top of the water distribution chamber 46, it has been found to break the effect of the siphon, allowing the water to maintain minimum or inactive water height in middle bowl 26.Those of skill in the art will appreciate that there are numerous ways to affect the siphon occurring between middle bowl 26 and lower bowl 24, this is just one of example of the same.","This anti-siphon hole 48 in the top of the water distribution chamber located in bowl 28 can also have a positive effect in providing water to the soil in bowl number one.","When in the active mode it can create a method of positive pressure water introduction into upper bowl 28.Although it is considered preferred to allow the water to wick up from bowl number 26 into bowl 28, it could be beneficial in certain situations in which more water is required for a specific plant and the addition water introduction into the soil has a positive effect.","However, as this positive pressure water inlet increases in size in relation the water flow or pressure created from the pump, located in bowl 24, it is possible to meter this flow by increasing or decreasing the diameter of this positive water pressure inlet.","FIGS.","6A and 6B show the base 12 of the fountain according to another implementation of the invention.","FIG.","6A shows the bottom 14 of the base being additionally, and adjustably, weighted with a suitable weighting material 68 (e.g., sand) Typical fountains made of stone, concrete, and any other heavy medium, do not require the ability have an adjustable weighted base as they very nature of their design is heavy.","However, with the recent use of polyresin as the construction medium for the fountain of the present invention, which allows them to be light weight enough to ship for mass merchandising and for easy installation by the end user, they are too light to withstand any type of weather and will fall over with small winds.","Simply making the fountain heavier is counter-productive since shipping costs will go up and the installation by the customer becomes more difficult.","According to the present design the fountain can ship in its lightweight format and the end user can then add sand or heavy material 68 to the bottom of the fountain to provide the weight necessary to withstand weather conditions.","In this embodiment (as described above), the battery location, combined with the weight chamber is unique.","By placing the battery 30 in the lowest possible location to establish a low center of gravity and then adding a chamber 67 below the battery compartment to be filled with a removable weighted material 68 will provide the best center of gravity for the fountain.","By placing the weighting material compartment 67 and battery compartment 22 close to each other, the issue or adding subtracting the weighted material becomes an issue for the end user and for methods of manufacturing.","First the method of manufacturing a poly resin fountain utilizes an outer shape for the exterior of the fountain and at the bottom base a panel is glued into place to seal the bottom of the fountain base to the outer shape thus providing rigidity to the outer structure and to finish the cosmetics of the bottom of the fountain.","This allows for a hollow inner structure which is both a cost and weight saving and the simplest method of manufacturing.","However, this method makes it difficult to make a separated chamber 67 to add material to since there is no inner structure to the fountain.","In the current design a male protrusion 66 which extends from the bottom base cap up into the inner body of the hollow fountain structure has been added.","The top of this protrusion 66 becomes the base in which the battery 30 can sit.","The diameter of the protrusion 66 is smaller than the inner diameter of the outer structure of the fountain.","The distance between the protrusion 66 and the outer structure provides for a conduit allowing the end user to add weighted material into the bottom of the fountain, the weight chamber.","The distance between the outer structure and the inner protrusion 66 is critical in that if it is too small it is difficult for the end user to add or remove weighted material and if it is too large, the base of the top of the protrusion 66 is not large enough to support the battery and any other object being stored in the battery compartment.","To help in providing the added room from the placement or removal of the weighted material 68, a small indent of any particular shape can be added the protrusion 66, thus maintaining adequate base area to support the battery while increasing the space between the outer structure and the protrusion 66 for ease of adding or removing the weighted material.","This method is preferred over other methods for adding or removing weight.","For example, an opening formed in the bottom base panel, with, for example, a plug to add or remove the weighted material, would require that the fountain be turned upside down to add the material.","This, in turn, would require that the hollow interior of the fountain have a separate panel molded and attached to the inner wall of the fountain.","This panel would have to be sealed to prevent the weighted material from leaking back into the body of the fountain when it is turned upside down to add the weighted material.","This added panel would significantly increase the manufacturing cost.","The battery base 16/compartment 22 is also unique to the poly resin fountains for manufacturing reasons as mentioned above, even without the ability to add weighted material.","By extending the outer edge of the battery base 16 to the inner dimension of the outer shape, which eliminates the ability to add weighted material, however provides a cost-effective method for production to establish a base for the battery.","FIG.","6B shows a clear view of the top 60 of the base 12.The top 60 includes a keyed slot 62 having keys 64.The keys 64 are configured to

water to be distributed to the exterior of the fountain.","This method does not allow for the ability to easily change or add new water features by the end user.","According to an implementation, the middle bowl 26 is molded with a large passageway 76 having an inner dimension configured to receive the water distribution plug 72 with hose 74 that can be inserted into the resin.","This removable plug 72 allows the end user to pull the tube 74 off of the water feature to be removed and re-attach a new water feature by pressing the water distribution plug in place on the new feature.","FIG.","8

principles.\",\n \"The garden fountain 10 includes a base 12, a lower or reservoir bowl 24, a middle bowl 26 and an upper or planter bowl 28.The base 12 can be made up of one or more parts and is shown in the present example having a footing 14, a central shaft 16 and a bowl support 18.A power button 20 can be disposed in any suitable location and is shown here integrated into the bowl support 18.A battery compartment 22 is preferably disposed in the base of the central shaft 16, or the footing 14 (if of suitable size) The connection of the lower bowl to the footing can be achieved in any suitable known manner.\",\n \"For example, a slot and groove mechanical engagement where the parts are fitted together and rotated to secure the connection could be used.\",\n \"Such slot and groove configuration could also be used to connect the middle bowl 26 to the lower bowl 24.O-rings or other water sealing means can be used in any relevant application for the connection of the various parts of the fountain.\",\n \"In addition, those of skill in the art will appreciated that each of the parts of the garden fountain 10 can be made of any suitable known material, which may include, but is not limited to, molded plastics.\",\n \"FIGS.\",\n \"2A and 2B show the battery compartment 22 having a battery 30 contained therein.\",\n \"In this preferred implementation the battery is rechargeable and the battery compartment is preferably sealed from water such that the user may easily access the same without any concerns relating to the water contained within the lower and middle bowls.\",\n \"Ideally, the battery compartment should have at least one opening to the outside air so as to prevent the formation of condensation in the compartment and thereby any negative effects to the battery as a result of the same.\",\n \"Those of skill in the art will appreciate that the access panel for the battery compartment can be configured in any suitable manner, such as for example, a sliding panel, a hinged panel, and may also include a locking mechanism.\",\n \"In one implementation, the rechargeable battery or batteries 30 can be recharged using a solar system (not shown), and/or using household electric power.\",\n \"Alternatively, the batteries can be made to be disposable.\",\n \"In addition to rechargeable power means, timing system 31 can be implemented where individual buttons are preset for predetermined time periods, or adjustable timing means are implemented.\",\n \"In other implementations, the power source for the fountain can be solar powered, A/C powered using 110 v, 210 v and/or DC powered using a 12 v battery.\",\n \"It is further contemplated that the garden fountain system may include a lighting system that provides accent lighting the fountain and/or the plant in the upper bowl planter.\",\n \"The positioning of the lights cans be within or out of the water.\",\n \"FIGS.\",\n \"3 and 5 illustrate one example of the disposition of the pump 32 within the shaft 23 positioned within the lower/reservoir bowl 24 and configured to support the middle bowl 26.The pump 32 includes a power connection 34 which is connected to the battery 30 positioned in the base 16.The pump 32 sits in the bottom of the shaft 23 and is configured to draw water from the lower/reservoir bowl 24 and the pump feeds the same to the middle bowl 26 via a tube 36 connected to a water input connection 40 in the center of the middle bowl 26.Referring to FIGS.\",\n \"3 and 4, the upper bowl 28, positioned siting within the middle bowl 26.In a preferred implementation, the upper bowl 28 is configured as planter.\",\n \"As shown in FIG.\",\n \"5, the upper bowl 28 includes a number of openings 42 at the bottom thereof.\",\n \"The openings 42 allow the transfer of water from a middle bowl 26, into upper bowl 28 when the water level rises in bowl 26 to a predetermined level.\",\n \"Bowl 26 has water introduced via a pump 32, (FIG.\",\n \"3), drawing water from bottom of a lower bowl 24, (i.e., a reservoir bowl).\",\n \"As shown in FIG.\",\n \"3, the pump can be located in the lower reservoir bowl 24, and as shown in the present example, the pump 32 is positioned within the shaft supporting the middle bowl 26.Those of skill in the art will appreciate that any suitable known type of pump 32 with an appropriate water intake can be used.\",\n \"According to one implementation, the pump 32 uses a 6-volt dc pump powered by the rechargeable battery 30 located in the base of the fountain.\",\n \"When the pump is turned on, the water is pumped from lower bowl 24 into the middle bowl 26.The water continues to rise until the water level reaches the pour spouts 25 of middle bowl 26, at which point the water level 5 reaches its maximum height or level in middle bowl 26 and the water pours over back into lower bowl 24.\",\n \"(See FIG.\",\n \"5) As shown above, upper bowl 28 sits in middle bowl 26.The distance between the base of middle bowl 26 and base of bowl 28, specifically the water inlets 42 of upper bowl 28 are crucial to the operation.\",\n \"The height of the water level in middle bowl 26 reaches at least to the bottom of the water inlets of upper bowl 28.Discs or spaces 43 can be added or subtracted to achieve the desired position of the base of the upper bowl 28 within the middle bowl 26.As will be evident from the above, height of the upper bowl 26 can be infinitely adjusted using the discs 43 depending on the water level desired/required for the plant in the upper bowl 28.According to one preferred implementation, a minimum height must at least reach the bottom of the water inlets 42 in upper bowl 28 in order for the soil 29 located in upper bowl 28 to be able to draw or wick the water up from middle bowl 26.Although shown in the form of openings, water inlets 42 can include a porous material 41 of any kind so as to prevent any soil from being undesirably being dispelled from the upper bowl 28 into middle bowl 26.As mentioned above, the height of upper bowl 28 in relation to middle bowl 26 will be adjustable.\",\n \"The purpose of an adjustable height is such that you can raise or lower the water level in upper bowl 28.This is beneficial since plants require different amounts of water for growing.\",\n \"In the current configuration one or more spacers 43 are used in between upper bowl 28 and middle bowl 26.Any number of or no spacers can be used.\",\n \"In the configuration of FIG.\",\n \"4, three (3) spacers 43 are shown.\",\n \"This gives a total of four (4) water level settings.\",\n \"The thickness of the spacers 43 can also be changed to accommodate other spacing options.\",\n \"In one preferred implementation, no spacer present allows upper bowl 28 to sit at its lowest possible setting, providing the highest water level in upper bowl 28.As you add a spacer between the upper bowl 28 and middle bowl 26, bowl 28 will increase in height over middle bowl 26 thus raising upper bowl 28 proportionally higher above middle bowl 26 lowering the water level or line in upper bowl 28.As you add another spacer, this water level will continue to lower in bowl 28 until you can add spacer so that upper bowl 28 water inlets 42 can be completely above the water level in middle bowl 26.The above description is referring to the water level in the active or pump on mode.\",\n \"This is when the water level is at its highest, but at no time does the water level rise above the maximum level provided by the waterspouts 25 in middle bowl 26.When in the active mode, or pump on mode and the maximum spacer 43 or height of upper bowl 28 is in use, the water level is raised in middle bowl 26 to the maximum height determined by the waterspouts 25.Upper bowl 28 being in its highest setting will only, when in active mode, have water coming in contact with the water inlets 42 in upper bowl.\",\n \"When the fountain is inactive, pump off, the water level will lower to a point just below the maximum water level in middle bowl 26.At this point the water level is lower than the bottom of the water inlets 42 in upper bowl 28.This then provides an air gap necessary for healthy plant growth allowing the soil to aerate, from the bottom up.\",\n \"In this same setting, when the fountain is in active mode, the water level in middle bowl 26 will rise to the maximum height provided by waterspouts 25 in bowl number 26.At such point, the water level will rise to allow the water inlets 42 in upper bowl 28 to come into contact with the water 5 in middle bowl 26.The resulting wicking effect allows the soil 29 in upper bowl 28 to wick the water up into bowl 28, providing water for the plant.\",\n \"The water level in upper bowl 28 can be adjusted through raising and lowering the bowl in relation to middle bowl 26 with any number of methods, fixed and mechanical.\",\n \"In addition, the water level in upper bowl 28 can be affected or adjusted to provide the proper amount of water to the plant in upper bowl 28 depending on if the fountain is active or inactive.\",\n \"The above description relates to the adjusting of the water level in upper bowl 28 in the active mode.\",\n \"If you adjust for the inactive mode, upper bowl 28 can be moved to, for example, the lowest setting.\",\n \"This position will place the water inlets 42 of upper bowl 28 to below the maximum water level of middle bowl 26.If the fountain is first active and thus raising the water level in bowl 26 to the maximum level and then turned inactive, the water level will lower slightly to just below the spout level 25.However, upper bowl 28 water inlets 42 can be set so that they are lower than middle bowl 28's maximum level.\",\n \"Therefore, the soil 29 in bowl 28 would continue to wick water up into bowl 28, even in the inactive mode.\",\n \"This provides additional water for different type of plants or weather conditions.\",\n \"This allows middle bowl 26 to act as a reservoir for upper bowl 28 until such time that the soil 29 in bowl 28 has wicked up the maximum amount of water it is capable of and or water has evaporated out of middle bowl 26.When either occurs, this will then lower the water level in middle bowl 26 to below the water inlets 42 in upper bowl 28, thus providing the necessary air gap 12 between upper bowl 28 and middle bowl number 26 to provide healthy conditions for good plant growth.\",\n \"The shape of the bottom of upper bowl 28 and the bottom of middle bowl 26 is also critical for proper water flow.\",\n \"Although there are numerous ways to introduce water into middle bowl 26, this description is for the current example being shown.\",\n \"The outlet of a water distribution tube 40 coming from the pump 32 located, for example, in lower bowl number 24, in a preferred embodiment needs to be just slightly higher than the maximum water level provided by the waterspouts 25 in middle bowl 26.This prevents the water from middle bowl 26 from siphoning back into lower bowl 24, thus maintaining the inactive water level in middle bowl 26 once initially filled to maximum water level when active.\",\n \"However, should the water siphon back into bowl 24, this can also be a benefit.\",\n \"In the current embodiment, there is a fill chamber 46 located in the bottom of upper bowl 28, which is female in shape, which matches to the male water distribution pipe 40 in middle bowl 26.This allows the water distribution pipe 40 or tube to be higher than the maximum water level in middle bowl 26 while allowing the water inlet ports 42, located in the corresponding female shape of the bottom of upper bowl 28 to operate below the maximum water level in middle bowl 26.In a preferred embodiment, water is only introduced into upper bowl 28 through the water inlet ports 42.This allows for a non-pressurized or turbulent water introduction into the soil.\",\n \"If the water from the distribution port in middle bowl 26 was directed straight directly into the soil 29 in upper bowl 28, it would erode the soil and causing excess soil to be introduced into the water system and erode the soil exposing the roots in the plant located in upper bowl 28.Although this system could have the water distributed to upper bowl 28 on in various manners, direct port from bowl number two into bowl number one.\",\n \"Another is a water distribution pipe pouring water into the top of bowl 28 from bowl 24.The preferred embodiment is to wick the water from the bottom up from bowl number 26 into upper bowl 28 initially when in the active mode then also in the inactive mode as described above.\",\n \"In the preferred embodiment, it has been found that the water distribution chamber 46 located in upper bowl 28, in relation to the air channels at the bottom of bowl 28, in relation to the water distribution port in middle bowl 26 can create a siphon effect after the fountain is inactive, thus siphoning all the water out of middle bowl 26 into lower bowl 24.This can be considered a positive effect if for example the plant in upper bowl 28 requires less water.\",\n \"To reduce this effect if a small hole 48 is introduced into the top of the water distribution chamber 46, it has been found to break the effect of the siphon, allowing the water to maintain minimum or inactive water height in middle bowl 26.Those of skill in the art will appreciate that there are numerous ways to affect the siphon occurring between middle bowl 26 and lower bowl 24, this is just one of example of the same.\",\n \"This anti-siphon hole 48 in the top of the water distribution chamber located in bowl 28 can also have a positive effect in providing water to the soil in bowl number one.\",\n \"When in the active mode it can create a method of positive pressure water introduction into upper bowl 28.Although it is considered preferred to allow the water to wick up from bowl number 26 into bowl 28, it could be beneficial in certain situations in which more water is required for a specific plant and the addition water introduction into the soil has a positive effect.\",\n \"However, as this positive pressure water inlet increases in size in relation the water flow or pressure created from the pump, located in bowl 24, it is possible to meter this flow by increasing or decreasing the diameter of this positive water pressure inlet.\",\n \"FIGS.\",\n \"6A and 6B show the base 12 of the fountain according to another implementation of the invention.\",\n \"FIG.\",\n \"6A shows the bottom 14 of the base being additionally, and adjustably, weighted with a suitable weighting material 68 (e.g., sand) Typical fountains made of stone, concrete, and any other heavy medium, do not require the ability have an adjustable weighted base as they very nature of their design is heavy.\",\n \"However, with the recent use of polyresin as the construction medium for the fountain of the present invention, which allows them to be light weight enough to ship for mass merchandising and for easy installation by the end user, they are too light to withstand any type of weather and will fall over with small winds.\",\n \"Simply making the fountain heavier is counter-productive since shipping costs will go up and the installation by the customer becomes more difficult.\",\n \"According to the present design the fountain can ship in its lightweight format and the end user can then add sand or heavy material 68 to the bottom of the fountain to provide the weight necessary to withstand weather conditions.\",\n \"In this embodiment (as described above), the battery location, combined with the weight chamber is unique.\",\n \"By placing the battery 30 in the lowest possible location to establish a low center of gravity and then adding a chamber 67 below the battery compartment to be filled with a removable weighted material 68 will provide the best center of gravity for the fountain.\",\n \"By placing the weighting material compartment 67 and battery compartment 22 close to each other, the issue or adding subtracting the weighted material becomes an issue for the end user and for methods of manufacturing.\",\n \"First the method of manufacturing a poly resin fountain utilizes an outer shape for the exterior of the fountain and at the bottom base a panel is glued into place to seal the bottom of the fountain base to the outer shape thus providing rigidity to the outer structure and to finish the cosmetics of the bottom of the fountain.\",\n \"This allows for a hollow inner structure which is both a cost and weight saving and the simplest method of manufacturing.\",\n \"However, this method makes it difficult to make a separated chamber 67 to add material to since there is no inner structure to the

tooth movement in orthodontic treatments.","Different approaches, both pre-clinically and clinically, have been attempted to achieve quicker results, but there are still many uncertainties and undetermined variables towards most of these techniques.","For example, some commercially available dental devices, such as AcceleDent Aura™, developed by OrthoAccel® Technologies, Inc., are offered to accelerate orthodontic treatment.","Patients are advised to wear such dental devices that mechanically stimulate teeth and braces in the form of micro-vibrations at a frequency of 30 Hz for 20 min per day.","To get the maximum desired results of accelerated orthodontic treatment, further studies are still needed to identify the variables of mechanical vibrational stimulation, such as frequency, strength, and duration.","It was discovered that treating cells, such as human osteoblasts and fibroblasts, with mechanical vibration for less than about 20 minutes, for example for about 5 minutes, daily at a frequency higher than about 80 Hz and with anisotropic acceleration magnitudes increases the number of cells over a period of time.","That a marked improvement of cell proliferation over prior-art treatment methods using a shorter treatment interval is surprising and not suggested by the prior art.","Various aspects of the present disclosure are developed based on such discovery.","According to an aspect of the present disclosure, a vibrational dental device that vibrates at a frequency higher than about 80 Hz is provided.","The vibrational dental device includes a mouthpiece and a motor connected to the mouthpiece.","The mouthpiece is configured to be provided between the occlusal surfaces of a user's teeth so as to be clamped by the user's teeth.","The motor is configured to vibrate the mouthpiece at a frequency higher than about 80 Hz, such as at a frequency between about 100 Hz to about 120 Hz, and with an acceleration magnitude ranging between about 0.03 G and about 0.4 G. When the motor is in operation and when the mouthpiece is clamped between the occlusal surfaces of a user's teeth, the vibrational dental device applies an axial vibratory force on the occlusal surfaces.","Clamping the teeth onto the mouthpiece will apply a load to the vibrator, which may have the effect of lowering the vibrational frequency of the mouthpiece measured in free air, as described below.","In some embodiments, the vibrational dental device may further include a sensor configured to detect the vibration variables of the device, such as frequency and acceleration magnitude.","When the mouthpiece of the vibrational dental device is clamped between the occlusal surfaces of a user's teeth, the sensor may detect the vibration variables proximate to the occlusal surfaces of the user's teeth.","In some embodiments, the sensor is a piezoelectric sensor.","According to another aspect of the present disclosure, a method for increasing cell proliferation is provided.","The method includes mechanically stimulating, using an exemplary vibrational dental device, cells for less than about 20 minutes, for example for about 5 minutes, daily at a frequency higher than about 80 Hz over a period of time.","The cells may include at least one of human osteoblasts and fibroblasts.","The period of time may extend for a couple of days up to a number of months, at the end of which, the number of the cells increases.","As described herein, an increase of cell proliferation or an increase of the number of cells can be represented by an increase of cell density.","According to another aspect of the present disclosure, a method for accelerating orthodontic tooth movement is described.","The method includes providing the mouthpiece of the vibrational dental device between the occlusal surfaces of a user's teeth to be clamped by the user's teeth.","The method further includes mechanically stimulating, using the vibrational dental device, cells of the user, including at least one of osteoblasts in alveolar bone and periodontal ligament fibroblasts, for less than about 20 minutes, for example for about 5 minutes, at a frequency higher than 80 Hz daily over a period of time.","In some embodiments, the method further includes applying an axial vibratory force on the occlusal surfaces by the vibrational dental device.","In some embodiments, the vibrational frequency and/or the acceleration magnitude generated by the vibrational dental device may be adjusted.","Such adjustment may depend on one or more factors, such as the speed of tooth movement and/or user's reported comfort level.","Reference will now be made in detail to embodiments and aspects of the present disclosure, examples of which are illustrated in the accompanying drawings.","Where possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.","FIG.","1A is a perspective view of an exemplary vibrational dental

FIGS.","1A-2, mouthpiece 102 and/or biteplate 114 are shaped to engage some or all of a user's teeth.","As described herein, the shape of mouthpiece 102 and/or biteplate 114 shown in FIGS.","1A-2 is only exemplary.","Mouthpiece 102 and/or biteplate 114 may have a C-shape as depicted, or a customized shape suitable for safe application of vibrational treatment to all or some of a user's

electrically connect base 104 with motor 106.As shown in FIGS.","1B and 1C, motor 106 is installed in extension 110 of mouthpiece 102.When mouthpiece 102 is attached to base 104, motor 106 resides in base 104.Base 104 further includes electronic circuitries (not shown), including a control circuitry and a power circuitry, for operating motor 106.Motor 106 may be any type of motor that can cause mouthpiece 102 or biteplate 114 to vibrate.","For example, motor 106 could be a vibration motor, piezoelectric motor, a linear motor, or an electromagnetic motor.","The frequency and/or strength of vibration caused by motor 106 can be adjusted by changing the voltage or current supplied to motor 106 by the electronic circuitries in base 104.For example, the voltage used for operating motor 106 may range from about 0.5 volt to about 4 volts.","The current supplied to an exemplary motor 106 may range from about 65 mA to about 100 mA.","Motor 106 may have any suitable mechanical configurations to cause mouthpiece 102 or biteplate 114 to vibrate axially.","FIG.","2 illustrates exemplary operation of vibrational dental device 100.As shown in FIG.","2, in one embodiment, motor 106 is a counter-weighted motor with a longitudinal axis parallel to the longitudinal axis of extension 110.Motor 106 may include a counterweight 212 that is off-axis from the longitudinal axis of motor 106.When the motor 106 rotates, as shown by the arrow 111 in FIG.","2, counterweight 212 moves up and down, causing the mouthpiece 102 to vibrate up and down, as shown by the arrows 113a-113d in FIG.","2.Accordingly, when the exemplary mouthpiece 102 is placed in a typodont or between a user's teeth, and when exemplary vibrational dental device 100 is turned on, the vibration of mouthpiece 102 will apply an axial vibratory force on the occlusal surfaces of the teeth.","For example, biteplate 114 of mouthpiece 102 may cyclically move axially between the occlusal surfaces of the

is clamped between the occlusal surfaces.","The sensors can be electrically connected to the electronic circuitries in base 104.Measurements of the sensors can be fed back to the control circuitry of motor 106 to adjust the acceleration magnitude and/or frequency of motor 106.For example, the detected acceleration magnitude and/or frequency may be compared to a desired acceleration magnitude and/or frequency, and the voltage and/or current supplied to motor 106 can be adjusted based on the comparison.","In some embodiments, motor 106 is configured to vibrate mouthpiece 102 at a frequency higher than about 80 Hz, such as at a frequency between about 100 Hz to about 120 Hz.","Motor 106 may be further configured to vibrate mouthpiece 102 at an acceleration magnitude ranging between about 0.03 G and about 0.2 G. As described herein, the vibrational frequency of mouthpiece 120 may vary from the rated “free-air” vibrational frequency of motor 106 due to the amount of biting force or load applied to mouthpiece 102, such as the force used to clamp vibrational dental device 100 in place.","For example, when motor 106 is configured to vibrate at a frequency of about 120 Hz, adding biting force or load to mouthpiece 102 may result in a lower vibrational frequency of mouthpiece 102 ranging from about 100 Hz to about 120 Hz.","Examples 1-11 described below illustrate the use of vibrational dental device 100 operating under these variables and its clinically relevant effects.","Example 1 A simulation was conducted to test and compare the vibration characteristics of a typodont caused by an exemplary embodiment of vibrational dental device 100 and a commercially available dental device, the AcceleDent Aura™.","In the simulation setup, the typodont was secured to a metal table.","The upper jaw of the typodont was hinged to the lower jaw and capable of opening and closing.","Each device was placed in the typodont (between the occlusal surfaces) and held in position by securely mounting a weight of about 0 to about 4 pounds on the upper jaw.","The weight simulates the biting force typically applied by a user to clamp the devices in place.","The simulation setup further included electronic instruments, including accelerometers, for measuring vibration characteristics of the typodont.","The accelerometers were placed directly on the devices and on the typodont.","FIGS.","3A-4P each show the measurement dataset of the accelerometer for two channels, channel 1 (“Ch1”) for detecting the vibration characteristics of the typodont and channel 2 (“Ch2”) for detecting the vibration characteristics of the device.","As shown in FIGS.","3A-4P, measurements of the accelerometers over the operation time of each device recorded increasing and decreasing accelerations of the devices and the typodont.","The measurement dataset of the accelerometers resembles a sinusoidal curve.","The distance from the bottom to the top of the sinusoidal curve is called the peak-to-peak G value or g-force (Gp-p).","In this simulation, the operation time of vibrational dental device 100 was about 5 minutes.","The operation time of AcceleDent Aura™ was about 20 minutes.","The maximum Gp-p values of the vibration of the typodont actuated by these two devices under different simulated biting forces (different weights) were measured using the accelerometers and other associated electronic instruments about one minute before the end of the operation time.","Therefore, measurement of the frequency and g-force for each channel was performed at the time point of about 4 minutes for vibrational dental device 100 and at the time point of about 19 minutes for AcceleDent Aura™.","The simulation was repeated for a second testing device of vibrational dental device 100 and a second

dental device 100 produced greater acceleration than the AcceleDent Aura™ at various simulated biting forces (under various weights).","When the typodont was fitted an aligner (as shown in FIG.","5A and Table 1), depending on the simulated biting force, the AcceleDent Aura™ caused very low acceleration levels of the typodont with g-force values from less than 0.01 G to no greater than 0.02 G. In contrast, vibrational dental device 100 resulted in higher acceleration levels of the typodont with g-force values ranging from about 0.04 G to about 0.076 G. In particular, the two-pound and four-pound weights (or simulated biting force) caused the AcceleDent Aura™'s measured average g-force values to drop to very low levels of 0.0135 G and 0.002 G, respectively.","When the typodont was without an aligner (as shown in FIG.","5B and Table 2), depending on the simulated biting force, the AcceleDent Aura™ similarly caused very low acceleration levels with g-force values from less than 0.01 G to no greater than 0.04 G. Again, in contrast, vibrational dental device 100 resulted in multi-fold higher acceleration levels with g-force values ranging from about 0.04 G to about 0.15 G.

dental device 100 and AcceleDent Aura™ produce distinct vibration frequencies, and accelerations, and are used for different treatment duration, but they produce about the same number of oscillations per treatment.","The different vibration variables of the AcceleDent Aura™ and vibrational dental device 100 may be perceived differently by cells residing in the alveolar bone and the periodontal tissue.","In this example, acceleration profiles of the two devices are quantified and compared, and the efficacy of the mechanical vibration generated by these two devices to stimulate cells, including osteoblasts, periodontal ligament fibroblasts, and osteoclasts was quantitatively evaluated and compared.","To measure the acceleration profiles of both vibrational dental device 100 and AcceleDent Aura™, an accelerometer Slamstick C (Mide Technology Corp, MA) was attached to the top surface of a mouthpiece and inserted into the mouth cavity of a volunteer as instructed by the manual of the manufacturer.","All data were recorded for 20 second intervals at a recording frequency of 800 Hz.","During recording, the mouthpiece was kept in the horizontal plane.","Fast Fourier Transform (FFT) was applied to determine the frequency content of the recordings.","For both vibrational dental device 100 and AcceleDent Aura™, three devices of each were tested and average peak acceleration magnitudes of the three devices in three orthogonal directions, including X-horizontal, Y-horizontal, and vertical dimensions were obtained.","Commercially available cells, including human osteoblasts, human periodontal ligament fibroblasts, and human osteoclasts (Lonza, Inc., Walkersville, Md.)","were cultured according to the manufacturer's instructions.","For all experiments, the cells were plated in multi-well tissue culture plates at a cell density of 7,500 cells/cm2 and placed in an incubator prior to vibration treatment.","The cells were taken out from the incubator immediately prior to vibration treatment.","The human osteoblasts, human periodontal ligament fibroblasts, and human osteoclasts samples were respectively separated into three groups, a first group subject to vibration treatment by AcceleDent Aura™, a second group subject to vibration treatment by an exemplary embodiment of vibrational dental device 100, and a control group handled identically to the other two groups but not subject to vibration treatment.","Vibration treatment was applied by placing the device between the cell culture plates and a plastic box.","The cell culture plates, the device, and the plastic box were securely fastened together by industrial elastic bands.","The plastic box and the industrial elastic bands isolated the vibrations generated by the devices from being transmitted to the experimental countertop.","A tri-axial accelerometer was directly attached to the top of the cell culture plates to verify the applied vibration frequency and acceleration magnitude.","Vibration treatment of the cells was applied daily at room temperature for a period of three days.","Each day, the first groups of osteoblasts, fibroblasts, and osteoclasts were subject to vibration treatment by AcceleDent Aura™ at a frequency of 30 Hz for 20 minutes.","The second groups of osteoblasts, fibroblasts, and osteoclasts were subject to vibration treatment by vibrational dental device 100 at a frequency from about 100 Hz to about 120 Hz for 5 minutes and subsequently left at room temperature for 15 minutes to match the 20 minutes room temperature exposure of the first groups.","The control groups were left at room temperate for 20 minutes without any vibration treatment.","For osteoblasts and periodontal ligament fibroblasts, cell proliferation or cell density (cells/cm2) over a three-day period was used as a marker for the cells' responsivity to the vibration stimuli.","A standard spectrophotometric MTS assay was used for determining cell density according to the manufacturer's instructions (XTT Assay, ATCC™).","The cell sample size for each group of osteoblasts and periodontal ligament fibroblasts was 5.Mean cell numbers of each group were calculated based on the measured cell densities of the cell samples of each group.","To quantify osteoclasts' responsivity to the vibration stimuli, TRAP optical density was measured over a three-day period.","The cell sample size for each group of osteoclast was 12.Datasets were presented as means and standard deviations.","The three groups were statistically compared to each other via Fisher tests.","A significance value of 0.05 was used for all datasets.","FIG.","6 and Table 4 show the average peak acceleration magnitudes of AcceleDent Aura™ and vibrational dental device 100 recorded with the accelerometer in three orthogonal directions.","As shown in FIG.","6 and Table 4, the average peak accelerations of the three sample devices of AcceleDent Aura™ were measured about 0.12 G in the medial-lateral or X-horizontal direction, about 0.15 G in the anterior-posterior or Y-horizontal direction, and about 0.15 G in the vertical direction.","The average peak accelerations of the three sample devices of vibrational dental device 100 were measured about 0.23 G in the medial-lateral or X-horizontal direction, about 0.33 G in the anterior-posterior Y-horizontal direction, and

0.18 G for the AcceleDent Aura™ devices and about 0.41 G for the vibrational dental devices 100.Combining the average acceleration magnitudes in all three directions resulted in an average Total Resultant acceleration magnitude of about 0.24 G for the AcceleDent Aura™ devices and about 0.41 G for the vibrational dental devices 100.As shown in FIG.","6, for both AcceleDent Aura™ and

peak acceleration magnitudes by using a vibration frequency that is about four times greater than that of AcceleDent Aura™.","FIG.","8 shows mean cell numbers of three groups of

vibration treatment.","Asterisks mark statistically significant differences samples subject to vibration treatment AcceleDent Aura™ and samples subject to vibration treatment by vibrational dental device 100.Surprisingly, as shown in FIG.","8, the group of osteoblasts subject to vibration treatment by vibrational dental device 100 had significantly greater (p<0.05) cell proliferation than the group of osteoblasts subject to vibration treatment by AcceleDent Aura™ on day 2 and day 3.Similarly, as shown in FIG.","9, the group of fibroblasts subject to vibration treatment by vibrational dental device 100 had significantly greater (p<0.05) cell proliferation than the group of fibroblasts subject to vibration treatment by AcceleDent Aura™ on day 2 and day 3.As shown in FIG.","10, both AcceleDent Aura™ and vibrational dental device 100 were capable of moderately increasing the activity of osteoclasts as compared with the control group.","This example demonstrates the surprising results that vibration treatment by vibrational dental device 100 enhanced proliferation of human osteoblasts and periodontal ligament fibroblasts to a significantly greater level than AcceleDent Aura™ The in vitro experimental results presented in this example suggest that different cell types and tissues, such as the human osteoblasts and human periodontal ligament fibroblasts, can be more responsive to the vibration variables used by vibrational dental device 100.For example, vibrational dental device 100 produces vibratory motions at a frequency from about 100 Hz to about 120 Hz, about four times of that of AcceleDent Aura™, with greater peak acceleration magnitudes That superior results could be obtained in one-fourth the time required by the AcceleDent Aura™ could result in superior clinical results in orthodontics, as shorter treatment periods generally correlate to better user compliance and adherence.","Additionally, the difference in the peak acceleration magnitude produced by AcceleDent Aura™ and vibrational dental device 100 was significant.","As shown in Table 1, while AcceleDent Aura™ produced peak accelerations on the order of 0.15 G in all three directions, the peak accelerations produced by vibrational dental device 100 in the horizontal direction was about six times of that in the vertical direction.","This spatial anisotropy in acceleration magnitudes generated by vibrational dental device 100 may have directly contributed to the greater proliferation rates of the periodontal ligament fibroblast and osteoblast samples as cells may sense vibrations preferentially in the horizontal direction.","The Total Resultant peak acceleration magnitude of vibrational dental device 100 was about 70% greater than that of AcceleDent Aura™ As shown in FIGS.","6 and 7, the greater peak acceleration magnitude of vibrational dental device 100 was achieved via a greater vibration frequency and not a greater displacement magnitude.","In fact, as shown in FIG.","7, the displacement magnitude produced by vibrational dental device 100 was an order of magnitude smaller than that produced by AcceleDent Aura™.","This may be clinically important because small displacements induced by vibrations could reduce discomfort to the patients, thereby correlating with better user compliance.","Example 3 An exemplary embodiment of

DESCRIPTION The disclosed embodiments relate to devices, systems, and methods for stimulating cell proliferation.\",\n \"Advantageously, embodiments of the present disclosure can be implemented in an orthodontic treatment for accelerating orthodontic tooth movement.\",\n \"Osteoblasts and fibroblasts are intimately involved in facilitating tooth movement and thus are typically targeted by techniques that aim at accelerating tooth movement in orthodontic treatments.\",\n \"Different approaches, both pre-clinically and clinically, have been attempted to achieve quicker results, but there are still many uncertainties and undetermined variables towards most of these techniques.\",\n \"For example, some commercially available dental devices, such as AcceleDent Aura™, developed by OrthoAccel® Technologies, Inc., are offered to accelerate orthodontic treatment.\",\n \"Patients are advised to wear such dental devices that mechanically stimulate teeth and braces in the form of micro-vibrations at a frequency of 30 Hz for 20 min per day.\",\n \"To get the maximum desired results of accelerated orthodontic treatment, further studies are still needed to identify the variables of mechanical vibrational stimulation, such as frequency, strength, and duration.\",\n \"It was discovered that treating cells, such as human osteoblasts and fibroblasts, with mechanical vibration for less than about 20 minutes, for example for about 5 minutes, daily at a frequency higher than about 80 Hz and with anisotropic acceleration magnitudes increases the number of cells over a period of time.\",\n \"That a marked improvement of cell proliferation over prior-art treatment methods using a shorter treatment interval is surprising and not suggested by the prior art.\",\n \"Various aspects of the present disclosure are developed based on such discovery.\",\n \"According to an aspect of the present disclosure, a vibrational dental device that vibrates at a frequency higher than about 80 Hz is provided.\",\n \"The vibrational dental device includes a mouthpiece and a motor connected to the mouthpiece.\",\n \"The mouthpiece is configured to be provided between the occlusal surfaces of a user's teeth so as to be clamped by the user's teeth.\",\n \"The motor is configured to vibrate the mouthpiece at a frequency higher than about 80 Hz, such as at a frequency between about 100 Hz to about 120 Hz, and with an acceleration magnitude ranging between about 0.03 G and about 0.4 G. When the motor is in operation and when the mouthpiece is clamped between the occlusal surfaces of a user's teeth, the vibrational dental device applies an axial vibratory force on the occlusal surfaces.\",\n \"Clamping the teeth onto the mouthpiece will apply a load to the vibrator, which may have the effect of lowering the vibrational frequency of the mouthpiece measured in free air, as described below.\",\n \"In some embodiments, the vibrational dental device may further include a sensor configured to detect the vibration variables of the device, such as frequency and acceleration magnitude.\",\n \"When the mouthpiece of the vibrational dental device is clamped between the occlusal surfaces of a user's teeth, the sensor may detect the vibration variables proximate to the occlusal surfaces of the user's teeth.\",\n \"In some embodiments, the sensor is a piezoelectric sensor.\",\n \"According to another aspect of the present disclosure, a method for increasing cell proliferation is provided.\",\n \"The method includes mechanically stimulating, using an exemplary vibrational dental device, cells for less than about 20 minutes, for example for about 5 minutes, daily at a frequency higher than about 80 Hz over a period of time.\",\n \"The cells may include at least one of human osteoblasts and fibroblasts.\",\n \"The period of time may extend for a couple of days up to a number of months, at the end of which, the number of the cells increases.\",\n \"As described herein, an increase of cell proliferation or an increase of the number of cells can be represented by an increase of cell density.\",\n \"According to another aspect of the present disclosure, a method for accelerating orthodontic tooth movement is described.\",\n \"The method includes providing the mouthpiece of the vibrational dental device between the occlusal surfaces of a user's teeth to be clamped by the user's teeth.\",\n \"The method further includes mechanically stimulating, using the vibrational dental device, cells of the user, including at least one of osteoblasts in alveolar bone and periodontal ligament fibroblasts, for less than about 20 minutes, for example for about 5 minutes, at a frequency higher than 80 Hz daily over a period of time.\",\n \"In some embodiments, the method further includes applying an axial vibratory force on the occlusal surfaces by the vibrational dental device.\",\n \"In some embodiments, the vibrational frequency and/or the acceleration magnitude generated by the vibrational dental device may be adjusted.\",\n \"Such adjustment may depend on one or more factors, such as the speed of tooth movement and/or user's reported comfort level.\",\n \"Reference will now be made in detail to embodiments and aspects of the present disclosure, examples of which are illustrated in the accompanying drawings.\",\n \"Where possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.\",\n \"FIG.\",\n \"1A is a perspective view of an exemplary vibrational dental device 100.FIG.\",\n \"1B is a partial perspective view of vibrational dental device 100.FIG.\",\n \"1C is a partial component view of vibrational dental device 100.As shown in FIGS.\",\n \"1A-1C, vibrational dental device 100 includes a mouthpiece 102, a base 104, and a motor 106.Mouthpiece 102 is removably attached to base 104.Mouthpiece 102 includes a biteplate 114 and a mouthpiece extension 110 configured to connect with base 104.In some embodiments, mouthpiece 102 and/or biteplate 114 can be configured to engage some or all of a user's teeth.\",\n \"For example, in the exemplary embodiments shown in FIGS.\",\n \"1A-2, mouthpiece 102 and/or biteplate 114 are shaped to engage some or all of a user's teeth.\",\n \"As described herein, the shape of mouthpiece 102 and/or biteplate 114 shown in FIGS.\",\n \"1A-2 is only exemplary.\",\n \"Mouthpiece 102 and/or biteplate 114 may have a C-shape as depicted, or a customized shape suitable for safe application of vibrational treatment to all or some of a user's teeth.\",\n \"The mouthpiece can be made to apply vibration directly to a user's teeth, or to aligners or other appliances applied to the teeth.\",\n \"Extension 110 may further include contacts 108 that electrically connect base 104 with motor 106.As shown in FIGS.\",\n \"1B and 1C, motor 106 is installed in extension 110 of mouthpiece 102.When mouthpiece 102 is attached to base 104, motor 106 resides in base 104.Base 104 further includes electronic circuitries (not shown), including a control circuitry and a power circuitry, for operating motor 106.Motor 106 may be any type of motor that can cause mouthpiece 102 or biteplate 114 to vibrate.\",\n \"For example, motor 106 could be a vibration motor, piezoelectric motor, a linear motor, or an electromagnetic motor.\",\n \"The frequency and/or strength of vibration caused by motor 106 can be adjusted by changing the voltage or current supplied to motor 106 by the electronic circuitries in base 104.For example, the voltage used for operating motor 106 may range from about 0.5 volt to about 4 volts.\",\n \"The current supplied to an exemplary motor 106 may range from about 65 mA to about 100 mA.\",\n \"Motor 106 may have any suitable mechanical configurations to cause mouthpiece 102 or biteplate 114 to vibrate axially.\",\n \"FIG.\",\n \"2 illustrates exemplary operation of vibrational dental device 100.As shown in FIG.\",\n \"2, in one embodiment, motor 106 is a counter-weighted motor with a longitudinal axis parallel to the longitudinal axis of extension 110.Motor 106 may include a counterweight 212 that is off-axis from the longitudinal axis of motor 106.When the motor 106 rotates, as shown by the arrow 111 in FIG.\",\n \"2, counterweight 212 moves up and down, causing the mouthpiece 102 to vibrate up and down, as shown by the arrows 113a-113d in FIG.\",\n \"2.Accordingly, when the exemplary mouthpiece 102 is placed in a typodont or between a user's teeth, and when exemplary vibrational dental device 100 is turned on, the vibration of mouthpiece 102 will apply an axial vibratory force on the occlusal surfaces of the teeth.\",\n \"For example, biteplate 114 of mouthpiece 102 may cyclically move axially between the occlusal surfaces of the teeth.\",\n \"In some embodiments, vibrational dental device 100 may further include one or more sensors (not shown), such as piezoelectric sensors, configured to detect the acceleration magnitude and/or frequency of the vibration of mouthpiece 102.For example, sensors may be placed on the outside or the inside edge of biteplate 114, proximate to the occlusal surfaces of the teeth when mouthpiece 102 is clamped between the occlusal surfaces.\",\n \"The sensors can be electrically connected to the electronic circuitries in base 104.Measurements of the sensors can be fed back to the control circuitry of motor 106 to adjust the acceleration magnitude and/or frequency of motor 106.For example, the detected acceleration magnitude and/or frequency may be compared to a desired acceleration magnitude and/or frequency, and the voltage and/or current supplied to motor 106 can be adjusted based on the comparison.\",\n \"In some embodiments, motor 106 is configured to vibrate mouthpiece 102 at a frequency higher than about 80 Hz, such as at a frequency between about 100 Hz to about 120 Hz.\",\n \"Motor 106 may be further configured to vibrate mouthpiece 102 at an acceleration magnitude ranging between about 0.03 G and about 0.2 G. As described herein, the vibrational frequency of mouthpiece 120 may vary from the rated “free-air” vibrational frequency of motor 106 due to the amount of biting force or load applied to mouthpiece 102, such as the force used to clamp vibrational dental device 100 in place.\",\n \"For example, when motor 106 is configured to vibrate at a frequency of about 120 Hz, adding biting force or load to mouthpiece 102 may result in a lower vibrational frequency of mouthpiece 102 ranging from about 100 Hz to about 120 Hz.\",\n \"Examples 1-11 described below illustrate the use of vibrational dental device 100 operating under these variables and its clinically relevant effects.\",\n \"Example 1 A simulation was conducted to test and compare the vibration characteristics of a typodont caused by an exemplary embodiment of vibrational dental device 100 and a commercially available dental device, the AcceleDent Aura™.\",\n \"In the simulation setup, the typodont was secured to a metal table.\",\n \"The upper jaw of the typodont was hinged to the lower jaw and capable of opening and closing.\",\n \"Each device was placed in the typodont (between the occlusal surfaces) and held in position by securely mounting a weight of about 0 to about 4 pounds on the upper jaw.\",\n \"The weight simulates the biting force typically applied by a user to clamp the devices in place.\",\n \"The simulation setup further included electronic instruments, including accelerometers, for measuring vibration characteristics of the typodont.\",\n \"The accelerometers were placed directly on the devices and on the typodont.\",\n \"FIGS.\",\n \"3A-4P each show the measurement dataset of the accelerometer for two channels, channel 1 (“Ch1”) for detecting the vibration characteristics of the typodont and channel 2 (“Ch2”) for detecting the vibration characteristics of the device.\",\n \"As shown in FIGS.\",\n \"3A-4P, measurements of the accelerometers over the operation time of each device recorded increasing and decreasing accelerations of the devices and the typodont.\",\n \"The measurement dataset of the accelerometers resembles a sinusoidal curve.\",\n \"The distance from the bottom to the top of the sinusoidal curve is called the peak-to-peak G value or g-force (Gp-p).\",\n \"In this simulation, the operation time of vibrational dental device 100 was about 5 minutes.\",\n \"The operation time of AcceleDent Aura™ was about 20 minutes.\",\n \"The maximum Gp-p values of the vibration of the typodont actuated by these two devices under different simulated biting forces (different weights) were measured using the accelerometers and other associated electronic instruments about one minute before the end of the operation time.\",\n \"Therefore, measurement of the frequency and g-force for each channel was performed at the time point of about 4 minutes for vibrational dental device 100 and at the time point of about 19 minutes for AcceleDent Aura™.\",\n \"The simulation was repeated for a second testing device of vibrational dental device 100 and a second testing device of AcceleDent Aura™.\",\n \"Therefore, the first and second vibration dental devices 100 tested are shown as vibrational dental device 100 (1) and vibrational dental device 100 (2) respectively in FIGS.\",\n \"3A-3P.\",\n \"Also, the first and second AcceleDent Aura™ devices are shown as AcceleDent Aura™ (1) and AcceleDent Aura™ (2) respectively in FIGS.\",\n \"4A-4P.\",\n \"The simulation was also repeated where the typodont was installed with and without an aligner, as indicated in the captions of FIGS.\",\n \"3A-4P.\",\n \"All measurement data was summarized in Table 1 as shown below.\",\n \"TABLE 1 G-force values (Gp-p) measured under different testing conditions.\",\n

caused by the two testing devices of vibrational dental device 100 and the two testing devices of AcceleDent Aura™.\",\n \"As shown in FIGS.\",\n \"5A and 5B, vibrational dental device 100 produced greater acceleration than the AcceleDent Aura™ at various simulated biting forces (under various weights).\",\n \"When the typodont was fitted an aligner (as shown in FIG.\",\n \"5A and Table 1), depending on the simulated biting force, the AcceleDent Aura™ caused very low acceleration levels of the typodont with g-force values from less than 0.01 G to no greater than 0.02 G. In contrast, vibrational dental device 100 resulted in higher acceleration levels of the typodont with g-force values ranging from about 0.04 G to about 0.076 G. In particular, the two-pound and four-pound weights (or simulated biting force) caused the AcceleDent Aura™'s measured average g-force values to drop to very low levels of 0.0135 G and 0.002 G, respectively.\",\n \"When the typodont was without an aligner (as shown in FIG.\",\n \"5B and Table 2), depending on the simulated biting force, the AcceleDent Aura™ similarly caused very low acceleration levels with g-force values from less than 0.01 G to no greater than 0.04 G. Again, in contrast, vibrational dental device 100 resulted in multi-fold higher acceleration levels with g-force values ranging from about 0.04 G to about 0.15 G.

the periodontal tissue.\",\n \"In this example, acceleration profiles of the two devices are quantified and compared, and the efficacy of the mechanical vibration generated by these two devices to stimulate cells, including osteoblasts, periodontal ligament fibroblasts, and osteoclasts was quantitatively evaluated and compared.\",\n \"To measure the acceleration profiles of both vibrational dental device 100 and AcceleDent Aura™, an accelerometer Slamstick C (Mide Technology Corp, MA) was attached to the top surface of a mouthpiece and inserted into the mouth cavity of a volunteer as instructed by the manual of the manufacturer.\",\n \"All data were recorded for 20 second intervals at a recording frequency of 800 Hz.\",\n \"During recording, the mouthpiece was kept in the horizontal plane.\",\n \"Fast Fourier Transform (FFT) was applied to determine the frequency content of the recordings.\",\n \"For both vibrational dental device 100 and AcceleDent Aura™, three devices of each were tested and average peak acceleration magnitudes of the three devices in three orthogonal directions, including X-horizontal, Y-horizontal, and vertical dimensions were obtained.\",\n \"Commercially available cells, including human osteoblasts, human periodontal ligament fibroblasts, and human osteoclasts (Lonza, Inc., Walkersville, Md.)\",\n \"were cultured according to the manufacturer's instructions.\",\n \"For all experiments, the cells were plated in multi-well tissue culture plates at a cell density of 7,500 cells/cm2 and placed in an incubator prior to vibration treatment.\",\n \"The cells were taken out from the incubator immediately prior to vibration treatment.\",\n \"The human osteoblasts, human periodontal ligament fibroblasts, and

embodiment of vibrational dental device 100, and a control group handled identically to the other two groups but not subject to vibration treatment.\",\n \"Vibration treatment was applied by placing the device between the cell culture plates and a plastic box.\",\n \"The cell culture plates, the device, and the plastic box were securely fastened together by industrial elastic bands.\",\n \"The

period of three days.\",\n \"Each day, the first groups of osteoblasts, fibroblasts, and osteoclasts were subject to vibration treatment by AcceleDent Aura™ at a frequency of 30 Hz for 20 minutes.\",\n \"The second groups of osteoblasts, fibroblasts, and osteoclasts were subject to vibration treatment by vibrational dental device 100 at a frequency from about 100 Hz to about 120 Hz for 5 minutes and subsequently left at room temperature for 15 minutes to match the 20 minutes room temperature exposure of the first groups.\",\n \"The control groups were left at room temperate for 20 minutes without any vibration treatment.\",\n \"For osteoblasts and periodontal ligament fibroblasts, cell proliferation or cell density (cells/cm2) over a three-day period was used as a marker for the cells' responsivity to the vibration stimuli.\",\n \"A standard spectrophotometric MTS assay was used for determining cell density according to the manufacturer's instructions (XTT Assay, ATCC™).\",\n \"The cell sample size for each group of osteoblasts and periodontal ligament fibroblasts was 5.Mean cell numbers of each group were calculated based on the measured cell densities of the cell samples of each group.\",\n \"To quantify osteoclasts' responsivity to the vibration stimuli, TRAP optical density was measured over a three-day period.\",\n \"The cell sample size for each group

(p<0.05) cell proliferation than the group of osteoblasts subject to vibration treatment by AcceleDent Aura™ on day 2 and day 3.Similarly, as shown in FIG.\",\n \"9, the group of fibroblasts subject

and day 3.As shown in FIG.\",\n \"10, both AcceleDent Aura™ and vibrational dental device 100 were capable of moderately increasing the activity of osteoclasts as compared with the control group.\",\n \"This example demonstrates the surprising results that vibration treatment by vibrational dental device 100 enhanced proliferation of human osteoblasts and periodontal ligament fibroblasts to a significantly greater level than AcceleDent Aura™ The in vitro experimental results presented in this example suggest that different cell types and tissues, such as the human osteoblasts and human periodontal ligament fibroblasts, can be more responsive to the vibration variables used by vibrational dental device 100.For example, vibrational dental device 100 produces vibratory motions at a frequency from about 100 Hz to about 120 Hz, about four times of that of AcceleDent Aura™, with greater peak acceleration magnitudes That superior results could be obtained in one-fourth the time required by the AcceleDent Aura™ could result in superior clinical results in orthodontics, as shorter treatment periods generally correlate to better user compliance and adherence.\",\n \"Additionally, the difference in the peak acceleration magnitude produced by AcceleDent Aura™ and vibrational dental device 100 was significant.\",\n \"As shown in Table 1, while AcceleDent Aura™ produced peak accelerations on the order of 0.15 G in all three directions, the peak accelerations produced by vibrational dental device 100 in the horizontal direction was about six times of that in the vertical direction.\",\n \"This spatial anisotropy in acceleration magnitudes generated by vibrational dental device 100 may have directly contributed to the greater proliferation rates of the periodontal ligament fibroblast and osteoblast samples as cells may sense vibrations preferentially in the horizontal direction.\",\n \"The Total Resultant peak acceleration magnitude of vibrational dental device 100 was about 70% greater than that of AcceleDent Aura™ As shown in FIGS.\",\n \"6 and 7, the greater peak acceleration magnitude of vibrational dental device 100 was achieved via a greater vibration frequency and not a greater displacement magnitude.\",\n \"In fact, as shown in FIG.\",\n \"7, the displacement magnitude produced by vibrational dental device 100 was an order of magnitude smaller than that produced by AcceleDent Aura™.\",\n \"This may be clinically important because small displacements induced by vibrations could reduce discomfort to the patients, thereby correlating with better user compliance.\",\n \"Example 3 An exemplary embodiment of vibrational dental device 100 is used to subject periodontal cells for a period of vibrational treatment.\",\n

temporarily implanted in a patient.","Many such implantable devices require the transcutaneous transfer of power and/or information with external components that are part of, or operate in conjunction with, the implanted components of the medical device.","Such external components are typically removably attached to the body of the patient.","One such type of medical device is a cochlear implant system, also commonly referred to as a cochlear prosthesis.","Cochlear implant systems provide the benefit of hear to individuals suffering from severe to profound hearing loss.","Hearing loss in such individuals is due to the absence or destruction of the hair cells in the cochlea which transduce acoustic signals into nerve impulses.","Cochlear implants essentially simulate the cochlear hair cells by directly delivering electrical stimulation to the auditory nerve fibers.","This causes the brain to perceive a hearing sensation resembling the natural hearing sensation normally delivered to the auditory nerve.","Conventional cochlear implant systems primarily include an external assembly directly or indirectly attached to the body of the patient (referred to herein as the recipient), and an internal assembly which is implanted in the patient.","The external assembly typically comprises one or more microphones for detecting sound, a speech processing unit that converts detected sound, particularly speech, into an electrical coded signal, a power source, and an external transcutaneous transfer coil.","The internal assembly typically comprises an internal transcutaneous transfer coil, a stimulator unit located within a recess of the temporal bone of the recipient, and an electrode array positioned in the recipient's cochlear.","Collectively, the external coil and the internal coil form an inductively-coupled transcutaneous transfer system.","The transfer of energy via this system is controlled to effect the transmission of the electrical coded signals, referred to herein as stimulation signals, and power signals from the external speech processing unit, to the implanted stimulator unit.","Similarly, the transcutaneous transfer system may be used to effect the transmission of telemetry data from the implanted stimulator unit to the exterior speech processing unit.","Conventionally, the communications link has been in the form of a radio frequency (RF) link, although other such links have been proposed and implemented.","Once a stimulation signal has been transmitted to the implanted transcutaneous transfer coil, it is provided to the implanted stimulator unit which processes the signal and outputs one or more signals to the intra-cochlear electrode assembly which applies the electrical stimulation directly to the auditory nerve of the recipient.","The speech processor unit has traditionally been worn on the body, such as by being attached to clothing, or by being supported on the ear of the recipient.","This latter configuration is commonly referred to as a BTE (behind the ear) configuration.","The speech processor unit is relatively expensive and susceptible to damage, especially in the hands of infants or small children, or when used in an unsuitable environment.","SUMMARY In one aspect of the invention, a method for operating an external component of a cochlear implant hearing system is disclosed.","The external component comprises a speech processor module is operable in a stand-alone mode of operation and a body-worn mode of operation, and a protective case.","The method comprises operating the speech processor module in the stand-alone mode, determining when the speech processor module is mounted in the case, and operating the speech processor module in the body-worn mode in response to determining that the speech processor module is mounted in the case.","In another aspect of the invention, a method for operating a cochlear implant hearing system is disclosed.","The method comprises operating, in a stand-alone mode of operation, a speech processor module having processing circuitry disposed in a housing, determining, via an operational mode controller, when the speech processor module is mounted in a protective case, and operating the speech processor module in a body-worn mode of operation in response to determining that the speech processor module is mounted in the case.","BRIEF DESCRIPTION

DESCRIPTION Embodiments of the present invention are directed to a speech processor module which may be implemented in more than one mode of operation of a hearing prosthesis.","Specifically, certain embodiments of the present invention are directed to a speech processor module that can be implemented as a component of in a behind-the-ear (BTE) speech processing unit, and as a component of a body-worn speech processing unit.","The present invention is also directed to an external component system for a hearing prosthesis that enables the dual-mode speech processor module to be worn on the body of a recipient rather than behind the recipient's ear.","Advantageously, certain embodiments of certain aspects of the present invention can be implemented such that the dual-mode speech processor module is protected from adverse environmental conditions, including certain recipients.","For example, in some embodiments described herein, the external component system includes a protective case which protects the speech processor module from infants, small children, mentally handicapped, etc., and/or allows the use of the speech processor module in environments traditionally considered to be unsuitable for prosthetic hearing devices.","As a result, embodiments of the present invention enable hearing prostheses to be worn by a wide range of recipients in a wide range of environments.","Embodiments of the present invention are described below in connection with one embodiment of an exemplary hearing prosthesis, a cochlear prosthesis (also referred to as a cochlear implant system, cochlear prosthetic device and the like; “cochlear implant system” herein).","Cochlear implant systems use direct electrical stimulation of auditory nerve cells to bypass absent or defective hair cells that normally transducer acoustic vibrations into neural activity.","Such devices generally use multi-contact electrodes inserted into the scala tympani of the cochlea so that the electrodes may differentially activate auditory neurons that normally encode differential pitches of sound.","Such devices are also used to treat a smaller number of patients with bilateral degeneration of the auditory nerve.","For such patients, a cochlear implant system provides stimulation of the cochlear nucleus in the brainstem.","FIG.","1A is a schematic diagram of an exemplary cochlear implant system 100 in which embodiments of the present invention may advantageously be implemented.","Cochlear implant system 100 comprises external component assembly 142 which is directly or indirectly attached to the recipient, and an internal component assembly 144 which is temporarily or permanently implanted in the recipient.","External component assembly 142 typically comprises a microphone 120 for detecting sound, a speech processing unit 116, a power source (not shown), and an external transmitter unit 106.External transmitter unit 106 comprises an external coil 108, and preferably, an alignment magnet 110 secured directly or indirectly to external coil 108.Speech processing unit 116 processes the output of microphone 120 that are positioned, in the depicted example, by the ear 122 of the recipient.","Speech processing unit 116 generates coded signals, referred to herein as a stimulation data signals, which are provided to external transmitter unit 106 via cable 118.Internal components 144 comprise an internal receiver unit 112, a stimulator unit 126, and an electrode array 134.Internal receiver unit 112 comprises an internal transcutaneous transfer coil 124, and preferably, an alignment magnet 140 fixed relative to internal coil 124.Internal receiver unit 112 and stimulator unit 126 are hermetically sealed within a housing 128.Internal coil 124 receives power and data from external coil 108.A cable 130 extends from stimulator unit 126 to cochlea 132 and terminates in electrode array 134.Signals generated by stimulator unit 126 are applied by array 134 to the basilar membrane 136, thereby stimulating the auditory nerve 138.Collectively, external coil 108 and internal coil 124 form an inductively-coupled coil system of a transcutaneous transfer apparatus 102.In one embodiment, external coil 108 transmits and receives electrical signals to/from internal coil 124 via a radio frequency (RF) link 114.In use, implantable receiver unit 112 may be positioned in a recess of the temporal bone adjacent ear 122 of the recipient.","As noted, embodiments of the present invention are directed to a speech processor module which may be implemented in more than one mode of operation in a hearing prosthesis such as cochlear implant system 100.FIG.","1B is a perspective view of one embodiment of a dual-mode speech processor module of the present invention.","In this embodiment, the dual-mode speech processor module of the present invention is configured to be used in a behind-the-ear (BTE) speech processing unit 178, similar to speech processing unit 116 illustrated in FIG.","1A.","Behind the ear (BTE) speech processing unit 178 comprises a speech processor module 180 that contains signal processing circuitry (not shown).","A detachable ear hook 182 is provided at one end of speech processor module 180 so as to allow the speech processor to be supported behind the outer ear of the recipient of the cochlear implant system.","A detachable power supply 184 comprising a rechargeable battery or other power source (not shown) is attached to speech processor module 180 to provide power to the module.","Speech processor module 180 utilizes a built-in microphone 186 that generates signals to the signal processing circuitry housed within the speech processor module.","Built-in microphone 186 is also referred to as internal microphone 186 herein.","Speech processor module 180 includes a headpiece connector 188 and an accessories connector 190 to connect to other components of the implementing cochlear implant system or other hearing prosthesis.","In operation, cables with an appropriately configured connector extends from speech processing module 180 to a headpiece and, possible, an accessory device, as described in detail below.","Speech processing unit 178 is configured to operate in a stand-alone manner; that is, as a behind-the-ear (BTE) speech processing unit.","However, speech processing unit 178 is susceptible to damage from rough handling, such as might be experienced when used by infants or small children.","It also may not be suitable for use in adverse environments, such as environments having airborne particulates or significant moisture.","To operate under such conditions, speech processor module 180 can operate in a body-worn mode of operation in an external component system.","One embodiment of an external component system 200 of a hearing prosthesis according to the present invention is depicted in FIGS.","2 and 3.External component system 200 operationally replaces external component assembly 142 of cochlear implant system 100 illustrated in FIG.","1A to convert the cochlear implant system from a prosthesis which may be readily damaged by the recipient and/or environment, to one which is more robust or rugged and, therefore, suitable for use by infants, children, mentally handicapped and other recipients, and/or worn by any recipient in one or more adverse environmental conditions.","In certain embodiments, external component system 200 provides protection for speech processor module 180.In the embodiment shown in FIG.","2, for example, a protective case 202 is included in external component system 200 to house speech processor module 180 and an on-board power supply 216.In certain embodiments, such protection includes protecting these components from ingress of fluid such as water.","In one embodiment, for example, protective case 202 is fluid resistant.","In another embodiment, protective case 202 prevents substantially all fluid ingress, even at elevated atmospheric pressure.","Similarly, in certain embodiments, protective case 202 is at least resistant to the ingress of dust or other particulates such as airborne fumes.","In other embodiments, protective case 202 is capable of providing protection against shocks and vibration, electromagnetic interference (EMI) and other environmental conditions which may adversely affect the operational performance, integrity, and/or lifespan of speech processor module 180.External component system 200 also comprises a one-piece headpiece 208 communicably coupled to speech processor module 180 via a cable 210.As will be described in greater detail below, headpiece 208 comprises the above-noted external transmitter unit 106 including external coil 108, and alignment magnet 110 mounted in a protective housing 220 that provides the same or similar protection of its components as protective case 202.Protective case 202 comprises a base member 204 and a cover member 206 which mechanically mate with each other to form a protective enclosure in which speech processor module 180 is secured.","Protective case 202 also comprises a tray 324 on which speech processor module 180 is removably mounted.","In addition, tray 324 is configured to have on-board power supply 216 mounted adjacent to speech processor module 180 to provide power to the speech processor module as described herein.","These and other components of protective case 202 are described in further detail below.","Referring again to FIG.","1B, speech processor module 180 is configured to be connected to a detachable power supply 184 when implemented in a stand-alone mode; here, as part of a behind the ear speech processing unit 178.When the recipient or their carer wishes speech processor module 180 to be protected by case 202, ear hook 182 and power supply 184 are detached from speech processor module 180, and the speech processor module is mounted on tray 324 of protective case 202.On-board power supply 216 is also mounted on tray 324.Cover member 206 is then secured to base member 204 to provide a sealed enclosure in which speech processor module 180 and on-board power supply 216 are protected.","The resulting external component system 200 is then used in place of the external component assembly 142 illustrated in FIG.","1A.","Protective case 202 is secured to the recipient using, for example, strap(s) threaded through brackets 218.As noted, in one embodiment, an on-board power supply 216 is included in protective case 202 to provide power to speech processor module 180 when the speech processor module is installed in protective case 202.Power supply 216 may be any suitable power supply now or later developed including but not limited to rechargeable batteries.","In one embodiment, on-board power supply 216 implements batteries which are conventional, commercially-available batteries, making them significantly less expensive than detachable power supply 184.Appropriate electrical connections are provided to transfer power from on-board power supply 216 to speech processor module 180.Referring to FIG.","3, speech processor module 180 has one or more connector pins 322 for connecting speech processor module 180 to detachable power supply 184 when implementing the stand-alone operational mode.","It should be appreciated that detachable power supply 184 has a connector (not shown) constructed and arranged to mate with the appropriate pin(s) 322 of speech processor module 180 to transfer power.","As shown in FIGS.","2 and 3, when speech processor module 180 is installed in protective case 202, on-board power supply 216 may not directly contact speech processor module 180.As a result, a connector similar to that implemented in detachable power supply 184 is not used in such embodiments to directly connect on-board power supply 216 to speech processor module 180.Rather, in the illustrative embodiment, a bridge connection is provided in protective case 202 to connect the appropriate pin(s) 322 of speech processor module 180 to terminals 328 of on-board power supply 216.In one embodiment, tray 324 provides the means to electrically connect on-board power supply 216 and speech processor module 180.Tray 324 also comprises apparatus to removably secure an installed power supply 216 and speech processor module 180 to prevent damage to themselves or the other components housed in protective case 202.In the embodiment shown in FIGS.","2 and 3, on-board power supply 216 is retained between a pair of vertical posts 326.Tray 324 also includes appropriately arranged contacts to electrically mate with terminals 328 on power supply 216 when the power supply is mounted on tray 324.In the embodiment shown, power supply 216 has terminals 328 disposed along a corner of the power supply.","Accordingly, tray 324 comprises contacts disposed at the junction of vertical columns 326 and the top surface of tray 324.It should be apparent to those of ordinary skill in the art that the contacts provided in tray 324 to electrically mate with terminals 328 of on-board power supply 216 may be located at any appropriate location and be configured in any way which will achieve a desired electrical connection.","As one of ordinary skill in the art would appreciate, the manner in which on-board power supply 216 is removably mounted on tray 324 can vary depending on a variety of factors including but not limited to the anticipated environment to which external component 200 and, in particular, protective case 202, will be exposed, the weight and mass of power supply 216, the weight distribution of the power supply, etc.","As noted, speech processor module 180 is removably mounted on tray 324.In the embodiment shown in FIG.","3 speech processor module 180 is shown detached from power supply 184 and ear hook 182, exposing pins 322 and raised guide surface 330.Raised guide surface 330 is received by a complementary channel in detachable power supply 184 to cause the power supply to properly mate with pins 322 when the power supply is attached to speech processor module 180.Tray 324 comprises a connector block 332 having in one embodiment, a mechanical and electrical interface similar to that of detachable power supply 184.That is, connector block 332 comprises a connector (not shown constructed and arranged to mate with pins 322 when speech processor 180 is mounted on tray 324.In addition, connector block 332 has an integrated channel 320 configured to slidingly receive raised guide surface 330 of speech processor module 180.To mount speech processor module 180 on tray 324, the speech processor module is positioned such that raised guide surface 330 is aligned with an open end of channel 320.As speech processor module 180 is slid into position, channel 320 and raised guide surface 330 cooperate to facilitate the mating of speech processor module 180 and the connector of connector block 332.In addition, raised guide surface 330 and channel 320 cooperate to securely retain speech processor module 180 to tray 324 when the speech processor module is mounted in protective case 202.It should be appreciated, however, that additional or alternative means may be employed to removably secure speech processor module 180 to tray 324.Embodiments of tray 324 may also include other components to facilitate the removable mounting of speech processor 180.For example, in the embodiment illustrated in FIG.","3, a brace 318 which is curved to abut or be adjacent with a curved surface of speech processor module 180 is provided.","In alternative embodiments, speech processor 180 is securely retained in protective case 324 using other techniques now or later developed.","When speech processor module 180 and on-board power supply 216 are mounted on tray 324, they are electrically connected to each other.","In the embodiment shown in FIGS.","2 and 3, for example, such electrical connection is provided by tray 324 so that additional components need not be included in protective case 202, and additional steps beyond mounting speech processor 180 and power supply 216 are not necessary to attain an electrical connection.","Specifically, wiring connects the power supply contacts (not shown) on tray 324 and the connector (not shown) on connector block 332 which mates with speech processor module 180.Such wiring may be integrated, for example, into platform 336 of tray 324, or may extend below platform 336.In the latter embodiment, tray 324 preferably does not rest in the bottom surface of base member 204; rather, it rests on support members to provide a space between platform 336 and base member 204 when tray 324 is secured to the base member.","As one of ordinary skill in the art would appreciate, the type of electrical connection provided can vary depending on the particular application.","For example, the pins and sockets used to establish the battery connection can be replaced with any other type of electrical connectors.","Also, one pin 322 can provide both the positive and ground connections for transferring power to speech processor module 180.As noted, base member 204 and cover member 206 are attached to each other to provide a protective enclosure for speech processor module 180 and on-board power supply 216.Cover member 206 and base member 204 are configured also to provide the recipient or carer access the enclosure to install or remove speech processor module 180 and power supply 216.In the embodiment shown in FIGS.","2 and 3, for example, cover member 206 is removable; that is, cover member 206 and base member 204 separate from each other to expose the interior of base member 204.It should be appreciated, however, that a portion or all of cover member 206 may be configured, for example, to rotate away from base member 204 to create an aperture through which speech processor module 180 and on-board power supply 216 can be passed.","Such rotation can be provided, for example, with mechanical hinges.","There are, of course, a myriad of other arrangements that may be implemented to provide the noted access.","For example, one or more rotating, sliding, removable, or other types of doors, panels, sides, etc., may be implemented in either or both, cover member 206 and base member 204.Cover member 206 and base member 204 may be formed of any material or combination of materials suitable for the intended recipient and environment.","For example, cover and base members 206, 204 may be formed of metallic material, ceramic material, polymeric material, composites or any combination thereof.","In addition, cover and base members 206, 204 may be opaque, translucent, transparent, etc., to provide a desired view of a desired portion of the interior of protective case 202 from the recipient, carer or third party.","In the exemplary embodiment shown in FIG.","3, protective case 202 contains a gasket 302 to seal protective case 202 when cover member 206 is joined with base member 204.As noted, embodiments of protective case 202 protect components mounted therein from a variety of environmental elements such as fluids, dust, etc.","Gasket 302 is appropriately configured and formed of the appropriate material to provide the desired degree of protection from at least the environmental elements of concern.","In the embodiment shown in FIGS.","2 and 3, gasket 302 is shaped to be disposed between the mating surfaces of cover member 206 and base member 204 when the cover and base are brought together to form protective case 202.Accordingly, gasket 302 takes the shape of the perimeter of protective case 202 at the location that the cover and base members meet.","In one particular embodiment, gasket 302 provides additional protection.","As shown in FIGS.","2 and 3, gasket 302 includes a contiguous sheath 334 of fluid-impermeable, resiliently flexible material extending across the interior of the gasket.","When installed in protective case 202, this embodiment of gasket 302 seals with the perimeter wall of base member 204.This causes sheath 334 to cover speech processor module 180 and power supply 216 mounted in base member 204.Thus, in addition to preventing ingress of at least selected environmental elements, gasket 302 and sheath 334 also protect components from those environmental elements which manage to penetrate protective casing 202.Sheath 334 can be manufactured from polymeric, elastomeric or other suitable materials.","In one embodiment, sheath 334 is transparent.","Protective case 202 comprises a fixation device to removably secure cover member 206 to base member 204.In the embodiment illustrated in FIGS.","2 and 3, such a fixation device comprises a combination of an appropriately located screw and threaded hole.","Specifically, sheath 334 has an orifice 304 formed therein that is adapted to allow passage of a threaded shaft of fixation screw 214 through sheath 334.Similarly, cover member 206 has an orifice 308 adapted to allow passage of the threaded shaft of screw 214.When cover member 206 and sheath 334 are assembled with based member 204, orifice 308 and orifice 304 are aligned with each other.","Screw 214 may then pass through orifice 308 in cover member 206, and orifice 304 in sheath 334 to threadingly engage a threaded hole 310 of a post 312 on tray 324.It should be appreciated by those of ordinary skill in the art that the implemented fixation device should not degrade the integrity of the protective features implemented in protective case 202.For example, in the above embodiment in which a fixation screw 214 is implemented, at the location of screw 214, an elastomeric grommet 314 is provided to help prevent ingress of fluid into the protective case at the site of screw 214.Additionally washers, o-rings and the like may also be used as appropriate.","External component system 200 also comprises a one-piece headpiece 208 communicably coupled to speech processor module 180 via a cable 210.As noted, headpiece 208 comprises the above-noted external transmitter unit 106 including external coil 108, and magnet 110 mounted in a housing 220 that provides the same or similar protection of its components as protective case 202.In accordance with one embodiment of the present invention, headpiece 208 also comprises a second microphone 212 mounted thereon which is operable when speech processor module 180 is installed in protective case 202.When speech processor module 180 is installed in protective case 202, microphone 186 cannot be used since it will be enclosed with protective case 202.As such, external component system 200 provides an alternate or replacement microphone 212, referred to as external microphone 212.Protective case 202 has an additional orifice (not shown) provided in base member 204 to permit cable 210 to be inserted into the case.","Cable 210 extends from headpiece 208 into case 202 to mate with connector 188 of speech processor module 180.The orifice may be sealed, for example, by a grommet 316 provided around the distal end of cable 210.For example, in one embodiment, grommet 316 and orifice are constructed and arranged to prevent water from entering protective case 202.As noted, protective case 202 provides protection for speech processor module 180 and on-board power supply 216.In the embodiments described above, such protection includes protecting the components from ingress of fluid, dust or other particulates such as airborne fumes.","In other embodiments, protective case 202 is capable of providing protection against electromagnetic interference (EMI).","In such embodiments, the interior surfaces of cover member 206 and base member 204 are coated with a conformal EMI coating such as that used in cellular phones, computer systems and other electronic devices that emit or are sensitive to electromagnetic radiation.","In addition, in such embodiments gasket 302 is an EMI gasket suitable for preventing EMI from escaping through the joined surfaces of cover member 206 and base member 204.In other embodiments, protective case 202 protects the components mounted therein from vibration and/or shock.","In such embodiments, tray 324 may be suspended on a shock- and vibration-absorbing material or elements such as resilient posts or extensions disposed in or integrated with base member 204.In addition, the dimensions of tray 324 may be somewhat less than the interior dimensions of protective case 202 to reduce the likelihood of shocks to tray 324 and the components mounted thereon.","FIG.","4 is a schematic interface diagram of one embodiment of speech processor module 180 illustrated in FIGS.","2 and 3.In the embodiment shown in FIG.","4, speech processor module 180 comprises four (4) interfaces, a headpiece interface 402, an accessories interface 404, a power supply interface 406, and a clinical/diagnostic interface 408.Each of the interfaces 402-408 is supported by one or more connectors as described above with references to FIGS.","2 and 3.It should be appreciated by those of ordinary skill in the art, however, that interfaces 402-408 may be implemented in one or more connectors configured differently than that described herein.","Headpiece interface 402 comprises a microphone signal line 410, an RF/telemetry signal line 411, a voltage signal line 412 and a ground signal line 414.In the embodiment shown in FIGS.","2 and 3, these signal lines are included in cable 210 connecting headpiece 208 and speech processor module 180 via connector 188.Accessories interface 404 comprises an input audio signal line 418, an auxiliary voltage input signal line 420, an output audio signal line 422 and a ground signal line 424.These signal lines are transmitted between an accessory device (not shown) and accessories connector 190 of speech processor module 180.Power supply interface 406 comprises a power supply identifier (ID) signal e 426, a voltage signal line 428, and a ground signal line 430.These signal lines are transmitted between one or more pins 322 of speech processor module 180 and either power supply 184 or power supply 216.Clinical/diagnostic interface 408 comprises an alarm signal line 432, data in and out signal lines 434, 436, and a ground signal line 438.These signal lines are transmitted between one or more pins 322 of speech processor module 180 and a diagnostic device or display (not shown).","It should be appreciated that in the embodiment of external component system 200 illustrated in FIGS.","2 and 3, the apertures in protective case 202 which provide access by cables that connect to accessory connector 190 (providing accessory interface 404), and pin(s) 322 (providing clinical interface 408) are not shown.","Such apertures, however, are the same or similar to those described above.","In an alternative embodiment, such interfaces are available only when speech processor module 180 implements the stand-alone mode of operation.","FIG.","5 is a functional block diagram of these components

in speech processor module 180 to determine which operational mode speech processor module 180 is to implement, and to select the appropriate internal inputs and outputs (that is, provided as part of speech processor module 180) and external inputs and outputs (that is, provided as part of external component system 200) to enable speech processor module 180 to function in the desired operational mode.","FIGS.","6A and 6B are schematic diagrams showing a portion of the interfaces utilized by one embodiment of speech processor module 180 when implemented in both modes of operation.","In FIG.","6A, speech processor module 180 has ear hook 182 and power supply 184 attached to facilitate, in this embodiment, use as a stand-alone behind-the-ear (BTE) speech processing unit 178.Detachable power supply 184 is shown schematically, and contains a rechargeable battery 606 and an identifier resistor 604.Detachable power supply 184 is connected to speech processor module 180 via power supply interface 406.External coil 208, also shown schematically, is connected to speech processor module 180 via headpiece interface 402.It should be appreciated, however, that when in the BTE operating mode, speech processor module 180 does not utilize external microphone 212, and external transmitter unit 106 (FIG.","1A) may be used with speech processor module 180 rather than exterior component system 200.In FIG.","6B, speech processor module 180 is not attached to ear hook 182 and power supply 184.Rather, it is coupled to on-board power supply 216 and an alarm system 524.As will be described in detail below, speech processor module 180 may be connected to a variety of external components implemented in protective case 202 or other components of external component system 200 depending on the implemented functionality.","The embodiment shown in FIG.","6B is just one exemplary implementation.","In addition, external coil 208, also shown schematically, is connected to speech processor module 180 via headpiece interface 402 in the arrangement shown in FIG.","6B.","Returning to FIG.","5, in accordance with one embodiment of the present invention, operation mode controller 500 comprises an operational mode selector 502 that determines which operational mode speech processor module 180 is to implement.","As noted, in the exemplary embodiment described herein, speech processor module 180 may be implemented in a stand-alone mode as illustrated in FIG.","1B, or a body-worn mode of operation as illustrated in FIGS.","2 and 3.Operational mode selector 502 makes the noted determination based on settings or conditions sensed or received by either an external operational mode sensor 504 implemented in protective case 202, or an internal operational mode sensor 506 implemented in speech processor module 180.In one embodiment, the operational mode of speech processor module 180 is determined based on the identification of the power supply that is connected to the speech processor module.","In such an embodiment, each power supply which may be utilized in connection with speech processor module 180 includes some identifying feature.","Information regarding the identifying feature is communicated to speech processor module 180 via power supply identification (ID) signal line 426.In such embodiments, an internal operational mode sensor 506 is implemented to detect the particular identifying feature.","For example, in the embodiment illustrated in FIGS.","6A and 6B, the identifying feature is the value of a resistor included in each power supply.","Referring to FIG.","6A, detachable power supply 184 comprises a resistor 604 and, in this example, a rechargeable battery 606.Resistor 604 identifies power supply 184 as a type of detachable power supply suitable for use when speech processor module 180 implements the stand-alone mode of operation.","Referring to FIG.","6B, on-board power supply 216 comprises a resistor 654 and, in this example, a rechargeable battery 656.Resistor 654 identifies power supply 216 as a type of on-board power supply suitable for use when speech processor module 180 implements the body-worn mode of operation.","In such embodiments, internal operational mode sensor 506 measures the resistance between ID signal line 426 and ground signal line 430 to determine the resistance of resistor 604 or 654.Based on this information, the type of power supply (i.e.","one suitable for use in stand-alone mode verse one suitable for use in body-worn mode), and the desired mode of operation is determined by operational mode selector 502.The operational mode 501 is then distributed to other functional components of controller 500 as described herein.","It should also be appreciated that operational mode sensors 504, 506 may utilize other information to determine the operational mode of speech processor module 180.For example, an externally-accessible switch may be provided on speech processor unit 180 (as part of internal sensor 506) or protective case 202 (as part of external sensor 504) to enable the recipient or another to manually select the operational mode.","When implemented as part of external sensor 504, such a switch is preferably configured to prevent infants and children from changing the operational mode, as well as to prevent accidental changing of the operational mode during the intended use of the body-worn external component system 200.When implemented as part of internal sensor 506, such a switch is inaccessible once speech processor module 180 is mounted in protective case 202 making such safeguards optional.","In another embodiment, external operational mode sensor 504 includes an infrared or other sensor responsive to signals transmitted by a remote control device.","Such an embodiment allows the recipient or their carer to transmit appropriate signals to select the desired operational mode of speech processor module 180.Based on the selected mode of operation 501 generated by operational mode selector 502, a microphone selector 510 of controller 500 selects which microphone to use.","When in the stand-alone mode of operation, internal microphone 186 is utilized, as shown in FIG.","6A.","When implementing the body-worn mode of operation, microphone 212 on headpiece 208 is utilized, as shown in FIG.","6B.","Microphone selector 510 forwards, connects, routes or otherwise provides the selected microphone 511 to other components of speech processor module 180.As one of ordinary skill in the art would appreciate, external microphone 212 may be located elsewhere; however, it is preferable that the external microphone be integrated into headpiece 208 as described herein.","Such an embodiment reduces the quantity of components while also protecting the external microphone.","In the embodiment shown in FIG.","5, speech processor module 180 comprises internal alarm(s) 526 to provide the recipient or another with visual and/or audible indications of predetermined conditions occurring in the speech processor module when the speech processor module implements the stand-alone mode of operations.","Exterior alarm(s) 524 are provided in protective case 202 to provide the same or similar alarms to the recipient or another when speech processor module 180 implements the body-worn mode of operation.","In accordance with one embodiment, operational mode controller 500 comprises an alarm selector 520 that selects whether alarm conditions are to be broadcast using internal alarms 526 or external alarms 524 based on the selected operational mode 501.Referring to FIG.","6B, external alarm(s) 524 is are implemented in protective case 202 and comprises a buzzer 662 that is actuated when an alarm condition 523 is detected.","External alarm(s) 524 incorporate a switch 658 that can be thrown by the recipient or another to generate a deactivate signal 521 to disable the alarm function.","Such a switch is preferably configured to prevent the unintended changing of the state of the alarm.","In one embodiment, external alarm 524 is implemented as part of connector block 332 on tray 324.In an alternative embodiment, external alarm 524 is implemented elsewhere on tray 324 or in protective case 202.It should be understood that the above embodiment of external alarm 524 is a buzzer.","Such an audible alarm may be located at the exterior surface of protective case 202, or may be located internal to protective case 202 with an adjacent aperture in the protective case to permit the sound to travel out of the case and be heard h the recipient.","In such alternative embodiments, such an aperture is constructed and arranged to provide a degree of protection analogous to that implemented in the other components and aspects of body-worn external components 200.It should also be appreciated that the type of alarm may include visual indicators in addition to or instead of the audible alarm noted above.","Alternatively, an audible sound may be injected into the audio path to be heard by only the recipient.","In one embodiment, the type of external alarm (indicator, enunciator, internal audio, etc.","), may be selected by the recipient or another, depending on the recipient and intended use of external components 200.As one of ordinary skill in the art would find apparent, any condition may be selected to be one which qualifies as an alarm condition.","For example, in one embodiment, alarm conditions include when the transcutaneous RF link fails such as by displacement of the external antenna.","In another embodiment, alarm conditions include when protective case 202 is opened.","It should also be appreciated that a hierarchical arrangement of alarm conditions may be established, each having a unique identifying alarm.","Speech processor module 180 comprises an internal display 536 comprising, for example, a liquid crystal display (LCD) and/or one or more LEDs that display performance criteria 531 of the module.","In one embodiment, performance criteria 531 comprises battery charge state, memory state, and/or other criteria.","In one embodiment, such performance criteria is not provided to the recipient when speech processor module 180 is mounted in protective case 202.In an alternative embodiment, a portion of cover member 206 and/or base member 204 are transparent to provide a view into a protective case 202 such that internal display 536 can be seen from a position external to protective case 202.In a further embodiment, illustrated in FIG.","5, protective case 202 provide an external display 534, for example, an LCD display located in cover member 206.A display selector 530 determines whether internal display 536 implemented in speech processor module 180 or external display 534 implemented in protective case 202 is to be used to provide the recipient or another with an indication of the noted performance criteria.","Such a determination is based on selected operational mode 501 generated by operational mode selector 501.Such information may be provided to external display 534 via, for example, data out signal line 436.Speech processor module 180 also comprises internal user controls 546 through which a recipient or another can program or otherwise select functional operating parameters in speech processor module 180.For example, in one embodiment, speech processor module 180 comprises internal user controls 546 which enable, for example, program selection, volume control, etc.","In one embodiment, such user controls are not provided to the recipient when speech processor module 180 is mounted in protective case 202.In a further embodiment, illustrated in FIG.","5, protective case 202 provides external user controls 544 located, for example, in cover member 206 and/or base member 204.A user controls selector 540 determines whether internal user controls 546 of speech processor module 180 or external user controls 544 in protective case 202 are to be utilized to provide the recipient or another with the ability to control speech processor module 180.Such a determination is made based on the operational mode 501 provided by operational mode selector 502.When external user controls 544 is selected (i.e.","speech processor module 180 implements the body-worn mode of operation), the transfer of information from the external interface is provided to selector 540 via, for example, data in signal line 434 (FIG.","4).","The user control inputs 541 generated by the selected user controls 544, 546 are forwarded, routed or otherwise provided to speech processor module 180 by selector 540.Speech processor module 180 includes internal on/off control 556, typically implemented as a manual switch in the housing of the speech processor module which can be manipulated by the recipient or another.","When speech processor module 180 is mounted in protective case 202, internal on/off control 556 is no longer accessible to control the power state of speech processor module 180.In one embodiment, no additional controls are provided.","In such an embodiment, protective case 202 must be opened to provide access to the above-noted on/off switch 556 on speech processor module 180.However, such an embodiment is inconvenient and time consuming to manage.","In addition, repeated access to protective case 202 will accelerate the wearing of gasket 302 or other seal implemented in protective case 202 to provide the above-noted protection.","In another embodiment, shown in FIG.","5, an external on/off control 554 is included in protective case 202 which can be activated without having to access the internal enclosure of the protective case.","In one embodiment, external on/off control 554 includes a reed switch or other magnetically-responsive component implemented in protective case 202.In the illustrated embodiment, the external on/off control 554 generates a signal which is forwarded, routed, passed, regenerated or otherwise provided to a power relay or other component speech processor module 180 to interrupt power to the module.","In an alternate embodiment, the magnetically-responsive component is electrically interposed between on-board power supply 216 and speech processor module 180.In this embodiment, speech processor module 180 is disconnected from the power supply when the magnetic field of a magnet such as alignment magnet 110 within headpiece 208 is brought to a location adjacent to the magnetically-responsive switch.","Other embodiments are also configured to cease operation when transcutaneous RF link has been broken.","For example, in one embodiment, internal on/off control 556 causes speech processor module 180 to periodically transmit an RF signal to implantable components 144, and wait for a response.","When no response is present, speech processor module 180 enters a standby mode or turns off.","If a standby mode is implemented, speech processor module 180 periodically transmits an RF signal while in the standby mode.","If a response is received, speech processor module 180 then fully activates, starts processing sound and retransmits signals to implantable component 144.In another embodiment, external on/off control module 554 can include a manually-activated switch located on the exterior of protective case 202.Such a switch is preferably configured to prevent children from changing the power state, and from accidental changing of the power state during the intended use of the body-worn external components 200.In addition to one or more of the above embodiments, speech processor module 180 can also be adapted to shut down whenever on-board power supply 216 is being charged.","In such an embodiment, protective case 202 also comprises charging circuitry (not shown) to allow power supply 216 to be recharged when case 202 is not in use.","In another embodiment, external on/off control 554 includes an infrared or other sensor responsive to signals transmitted by a remote device operated by the recipient or their carer.","In the case of adults, the present invention provides a recipient with the flexibility of using their speech processor module 180 in a moist environment.","For infants and small children, the present invention also can be used in the comfort that the speech processor is less likely to be damaged than would be the case where the speech processor unit is used in the stand-alone mode.","The case 202 is also potentially advantageous in that it can serve to assist in preventing tampering of speech processor module 180 by a child recipient or a third party."]],"string":"[\n [\n \"TRANSFORMABLE SPEECH PROCESSOR MODULE FOR A HEARING

herein.\",\n \"BACKGROUND Field of the Invention The present invention relates to a hearing prosthesis and, more particularly, a transformable speech processor module for a hearing prosthesis.\",\n \"Related Art The use of medical devices to provide therapy to individuals for various medical conditions has become more widespread as the advantages and benefits of such devices become more widely appreciated and accepted throughout the population.\",\n \"In particular, devices such as implantable pacemakers, defibrillators, functional electrical stimulation devices such as hearing prostheses, organ assist or replacement devices, and other medical devices, have been successful in performing life saving and/or lifestyle enhancement functions for a number of individuals.\",\n \"Many such medical devices often include one or more sensors, processors, controllers or other functional electrical components that are permanently or temporarily implanted in a patient.\",\n \"Many such implantable devices require the transcutaneous transfer of power and/or information with external components that are part of, or operate in conjunction with, the implanted components of the medical device.\",\n \"Such external components are typically removably attached to the body of the patient.\",\n \"One such type of medical device is a cochlear implant system, also commonly referred to as a cochlear prosthesis.\",\n \"Cochlear implant systems provide the benefit of hear to individuals suffering from severe to profound hearing loss.\",\n \"Hearing loss in such individuals is due to the absence or destruction of the hair cells in the cochlea which transduce acoustic signals into nerve impulses.\",\n \"Cochlear implants essentially simulate the cochlear hair cells by directly delivering electrical stimulation to the auditory nerve fibers.\",\n \"This causes the brain to perceive a hearing sensation resembling the natural hearing sensation normally delivered to the auditory nerve.\",\n \"Conventional cochlear implant systems primarily include an external assembly directly or indirectly attached to the body of the patient (referred to herein as the recipient), and an internal assembly which is implanted in the patient.\",\n \"The external assembly typically comprises one or more microphones for detecting sound, a speech processing unit that converts detected sound, particularly speech, into an electrical coded signal, a power source, and an external transcutaneous transfer coil.\",\n \"The internal assembly typically comprises an internal transcutaneous transfer coil, a stimulator unit located within a recess of the temporal bone of the recipient, and an electrode array positioned in the recipient's cochlear.\",\n \"Collectively, the external coil and the internal coil form an inductively-coupled transcutaneous transfer system.\",\n \"The transfer of energy via this system is controlled to effect the transmission of the electrical coded signals, referred to herein as stimulation signals, and power signals from the external speech processing unit, to the implanted stimulator unit.\",\n \"Similarly, the transcutaneous transfer system may be used to effect the transmission of telemetry data from the implanted stimulator unit to the exterior speech processing unit.\",\n \"Conventionally, the communications link has been in the form of a radio frequency (RF) link, although other such links have been proposed and implemented.\",\n \"Once a stimulation signal has been transmitted to the implanted transcutaneous transfer coil, it is provided to the implanted stimulator unit which processes the signal and outputs one or more signals to the intra-cochlear electrode assembly which applies the electrical stimulation directly to the auditory nerve of the recipient.\",\n \"The speech processor unit has traditionally been worn on the body, such as by being attached to clothing, or by being supported on the ear of the recipient.\",\n \"This latter configuration is commonly referred to as a BTE (behind the ear) configuration.\",\n \"The speech processor unit is relatively expensive and susceptible to damage, especially in the hands of infants or small children, or when used in an unsuitable environment.\",\n \"SUMMARY In one aspect of the invention, a method for operating an external component of a cochlear implant hearing system is disclosed.\",\n \"The external component comprises a speech processor module is operable in a stand-alone mode of operation and a body-worn mode of operation, and a protective case.\",\n \"The method comprises operating the speech processor module in the stand-alone mode, determining when the speech processor module is mounted in the case, and operating the speech processor module in the body-worn mode in response to determining that the speech processor module is mounted in the case.\",\n \"In another aspect of the invention, a method for operating a cochlear implant hearing system is disclosed.\",\n \"The method comprises operating, in a stand-alone mode of operation, a speech processor module having processing circuitry disposed in a housing, determining, via an operational mode controller, when the speech processor module is mounted in a protective case, and operating the speech processor module in a body-worn mode of operation in response to determining that the speech processor module is mounted in the case.\",\n \"BRIEF DESCRIPTION OF THE DRAWINGS FIG.\",\n \"1A is a perspective view of one embodiment of a hearing prosthesis

present invention are directed to a speech processor module which may be implemented in more than one mode of operation of a hearing prosthesis.\",\n \"Specifically, certain embodiments of the present invention are directed to a speech processor module that can be implemented as a component of in a behind-the-ear (BTE) speech processing unit, and as a component of a body-worn speech processing unit.\",\n \"The present invention is also directed to an external component system for a hearing prosthesis that enables the dual-mode speech processor module to be worn on the body of a recipient rather than behind the recipient's ear.\",\n \"Advantageously, certain embodiments of certain aspects of the present invention can be implemented such that the dual-mode speech processor module is protected from adverse environmental conditions, including certain recipients.\",\n \"For example, in some embodiments described herein, the external component system includes a protective case which protects the speech processor module from infants, small children, mentally handicapped, etc., and/or allows the use of the speech processor module in environments traditionally considered to be unsuitable for prosthetic hearing devices.\",\n \"As a result, embodiments of the present invention enable hearing prostheses to be worn by a wide range of recipients in a wide range of environments.\",\n \"Embodiments of the present invention are described below in connection with one embodiment of an exemplary hearing prosthesis, a cochlear prosthesis (also referred to as a cochlear implant system, cochlear prosthetic device and the like; “cochlear implant system” herein).\",\n \"Cochlear implant systems use direct electrical stimulation of auditory nerve cells to bypass absent or defective hair cells that normally transducer acoustic vibrations into neural activity.\",\n \"Such devices generally use multi-contact electrodes inserted into the scala tympani of the cochlea so that the electrodes may differentially activate auditory neurons that normally encode differential pitches of sound.\",\n \"Such devices are also used to treat a smaller number of patients with bilateral degeneration of the auditory nerve.\",\n \"For such patients, a cochlear implant system provides stimulation of the cochlear nucleus in the brainstem.\",\n \"FIG.\",\n \"1A is a schematic diagram of an exemplary cochlear implant system 100 in which embodiments of the present invention may advantageously be implemented.\",\n \"Cochlear implant system 100 comprises external component assembly 142 which is directly or indirectly attached to the recipient, and an internal component assembly 144 which is temporarily or permanently implanted in the recipient.\",\n \"External component assembly 142 typically comprises a microphone 120 for detecting sound, a speech processing unit 116, a power source (not shown), and an external transmitter unit 106.External transmitter unit 106 comprises an external coil 108, and preferably, an alignment magnet 110 secured directly or indirectly to external coil 108.Speech processing unit 116 processes the output of microphone 120 that are positioned, in the depicted example, by the ear 122 of the recipient.\",\n \"Speech processing unit 116 generates coded signals, referred to herein as a stimulation data signals, which are provided to external transmitter unit 106 via cable 118.Internal components 144 comprise an internal receiver unit 112, a stimulator unit 126, and an electrode array 134.Internal receiver unit 112 comprises an internal transcutaneous transfer coil 124, and preferably, an alignment magnet 140 fixed relative to internal coil 124.Internal receiver unit 112 and stimulator unit 126 are hermetically sealed within a housing 128.Internal coil 124 receives power and data from external coil 108.A cable 130 extends from stimulator unit 126 to cochlea 132 and terminates in electrode array 134.Signals generated by stimulator unit 126 are applied by array 134 to the basilar membrane 136, thereby stimulating the auditory nerve 138.Collectively, external coil 108 and internal coil 124 form an inductively-coupled coil system of a transcutaneous transfer apparatus 102.In one embodiment, external coil 108 transmits and receives electrical signals to/from internal coil 124 via a radio frequency (RF) link 114.In use, implantable receiver unit 112 may be positioned in a recess of the temporal bone adjacent ear 122 of the recipient.\",\n \"As noted, embodiments of the present invention are directed to a speech processor module which may be implemented in more than one mode of operation in a hearing prosthesis such as cochlear implant system 100.FIG.\",\n \"1B is a perspective view of one embodiment of a dual-mode speech processor module of the present invention.\",\n \"In this embodiment, the dual-mode speech processor module of the present invention is configured to be used in a behind-the-ear (BTE) speech processing unit 178, similar to speech processing unit 116 illustrated in FIG.\",\n \"1A.\",\n \"Behind the ear (BTE) speech processing unit 178 comprises a speech processor module 180 that contains signal processing circuitry (not shown).\",\n \"A detachable ear hook 182 is provided at one end of speech processor module 180 so as to allow the speech processor to be supported behind the outer ear of the recipient of the cochlear implant system.\",\n \"A detachable power supply 184 comprising a rechargeable battery or other power source (not shown) is attached to speech processor module 180 to provide power to the module.\",\n \"Speech processor module 180 utilizes a built-in microphone 186 that generates signals to the signal processing circuitry housed within the speech processor module.\",\n \"Built-in microphone 186 is also referred to as internal microphone 186 herein.\",\n \"Speech processor module 180 includes a headpiece connector 188 and an accessories connector 190 to connect to other components of the implementing cochlear implant system or other hearing prosthesis.\",\n \"In operation, cables with an appropriately configured connector extends from speech processing module 180 to a headpiece and, possible, an accessory device, as described in detail below.\",\n \"Speech processing unit 178 is configured to operate in a stand-alone manner; that is, as a behind-the-ear (BTE) speech processing unit.\",\n \"However, speech processing unit 178 is susceptible to damage from rough handling, such as might be experienced when used by infants or small children.\",\n \"It also may not be suitable for use in adverse environments, such as environments having airborne particulates or significant moisture.\",\n \"To operate under such conditions, speech processor module 180 can operate in a body-worn mode of operation in an external component system.\",\n \"One embodiment of an external component system 200 of a hearing prosthesis according to the present invention is depicted in FIGS.\",\n \"2 and 3.External component system 200 operationally replaces external component assembly 142 of cochlear implant system 100 illustrated in FIG.\",\n \"1A to convert the cochlear implant system from a prosthesis which may be readily damaged by the recipient and/or environment, to one which is more robust or rugged and, therefore, suitable for use by infants, children, mentally handicapped and other recipients, and/or worn by any recipient in one or more adverse environmental conditions.\",\n \"In certain embodiments, external component system 200 provides protection for speech processor module 180.In the embodiment shown in FIG.\",\n \"2, for example, a protective case 202 is included in external component system 200 to house speech processor module 180 and an on-board power supply 216.In certain embodiments, such protection includes protecting these components from ingress of fluid such as water.\",\n \"In one embodiment, for example, protective case 202 is fluid resistant.\",\n \"In another embodiment, protective case 202 prevents substantially all fluid ingress, even at elevated atmospheric pressure.\",\n \"Similarly, in certain embodiments, protective case 202 is at least resistant to the ingress of dust or other particulates such as airborne fumes.\",\n \"In other embodiments, protective case 202 is capable of providing protection against shocks and vibration, electromagnetic interference (EMI) and other environmental conditions which may adversely affect the operational performance, integrity, and/or lifespan of speech processor module 180.External component system 200 also comprises a one-piece headpiece 208 communicably coupled to speech processor module 180 via a cable 210.As will be described in greater detail below, headpiece 208 comprises the above-noted external transmitter unit 106 including external coil 108, and alignment magnet 110 mounted in a protective housing 220 that provides the same or similar protection of its components as protective case 202.Protective case 202 comprises a base member 204 and a cover member 206 which mechanically mate with each other to form a protective enclosure in which speech processor module 180 is secured.\",\n \"Protective case 202 also comprises a tray 324 on which speech processor module 180 is removably mounted.\",\n \"In addition, tray 324 is configured to have on-board power supply 216 mounted adjacent to speech processor module 180 to provide power to the speech processor module as described herein.\",\n \"These and other components of protective case 202 are described in further detail below.\",\n \"Referring again to FIG.\",\n \"1B, speech processor module 180 is configured to be connected to a detachable power supply 184 when implemented in a stand-alone mode; here, as part of a behind the ear speech processing unit 178.When the recipient or their carer wishes speech processor module 180 to be protected by case 202, ear hook 182 and power supply 184 are detached from speech processor module 180, and the speech processor module is mounted on tray 324 of protective case 202.On-board power supply 216 is also mounted on tray 324.Cover member 206 is then secured to base member 204 to provide a sealed enclosure in which speech processor module 180 and on-board power supply 216 are protected.\",\n \"The resulting external component system 200 is then used in place of the external component assembly 142 illustrated in FIG.\",\n \"1A.\",\n \"Protective case 202 is secured to the recipient using, for example, strap(s) threaded through brackets 218.As noted, in one embodiment, an on-board power supply 216 is included in protective case 202 to provide power to speech processor module 180 when the speech processor module is installed in protective case 202.Power supply 216 may be any suitable power supply now or later developed including but not limited to rechargeable batteries.\",\n \"In one embodiment, on-board power supply 216 implements batteries which are conventional, commercially-available batteries, making them significantly less expensive than detachable power supply 184.Appropriate electrical connections are provided to transfer power from on-board power supply 216 to speech processor module 180.Referring to FIG.\",\n \"3, speech processor module 180 has one or more connector pins 322 for connecting speech processor module 180 to detachable power supply 184 when implementing the stand-alone operational mode.\",\n \"It should be appreciated that detachable power supply 184 has a connector (not shown) constructed and arranged to mate with the appropriate pin(s) 322 of speech processor module 180 to transfer power.\",\n \"As shown in FIGS.\",\n \"2 and 3, when speech processor module 180 is installed in protective case 202, on-board power supply 216 may not directly contact speech processor module 180.As a result, a connector similar to that implemented in detachable power supply 184 is not used in such embodiments to directly connect on-board power supply 216 to speech processor module 180.Rather, in the illustrative embodiment, a bridge connection is provided in protective case 202 to connect the appropriate pin(s) 322 of speech processor module 180 to terminals 328 of on-board power supply 216.In one embodiment, tray 324 provides the means to electrically connect on-board power supply 216 and speech processor module 180.Tray 324 also comprises apparatus to removably secure an installed power supply 216 and speech processor module 180 to prevent damage to themselves or the other components housed in protective case 202.In the embodiment shown in FIGS.\",\n \"2 and 3, on-board power supply 216 is retained between a pair of vertical posts 326.Tray 324 also includes appropriately arranged contacts to electrically mate with terminals 328 on power supply 216 when the power supply is mounted on tray 324.In the embodiment shown, power supply 216 has terminals 328 disposed along a corner of the power supply.\",\n \"Accordingly, tray 324 comprises contacts disposed at the junction of vertical columns 326 and the top surface of tray 324.It should be apparent to those of ordinary skill in the art that the contacts provided in tray 324 to electrically mate with terminals 328 of on-board power supply 216 may be located at any appropriate location and be configured in any way which will achieve a desired electrical connection.\",\n \"As one of ordinary skill in the art would appreciate, the manner in which on-board power supply 216 is removably mounted on tray 324 can vary depending on a variety of factors including but not limited to the anticipated environment to which external component 200 and, in particular, protective case 202, will be exposed, the weight and mass of power supply 216, the weight distribution of the power supply, etc.\",\n \"As noted, speech processor module 180 is removably mounted on tray 324.In the embodiment shown in FIG.\",\n \"3 speech processor module 180 is shown detached from power supply 184 and ear hook 182, exposing pins 322 and raised guide surface 330.Raised guide surface 330 is received by a complementary channel in detachable power supply 184 to cause the power supply to properly mate with pins 322 when the power supply is attached to speech processor module 180.Tray 324 comprises a connector block 332 having in one embodiment, a mechanical and electrical interface similar to that of detachable power supply 184.That is, connector block 332 comprises a connector (not shown constructed and arranged to mate with pins 322 when speech processor 180 is mounted on tray 324.In addition, connector block 332 has an integrated channel 320 configured to slidingly receive raised guide surface 330 of speech processor module 180.To mount speech processor module 180 on tray 324, the speech processor module is positioned such that raised guide surface 330 is aligned with an open end of channel 320.As speech processor module 180 is slid into position, channel 320 and raised guide surface 330 cooperate to facilitate the mating of speech processor module 180 and the connector of connector block 332.In addition, raised guide surface 330 and channel 320 cooperate to securely retain speech processor module 180 to tray 324 when the speech processor module is mounted in protective case 202.It should be appreciated, however, that additional or alternative means may be employed to removably secure speech processor module 180 to tray 324.Embodiments of tray 324 may also include other components to facilitate the removable mounting of speech processor 180.For example, in the embodiment illustrated in FIG.\",\n \"3, a brace 318 which is curved to abut or be adjacent with a curved surface of speech processor module 180 is provided.\",\n \"In alternative embodiments, speech processor 180 is securely retained in protective case 324 using other techniques now or later developed.\",\n \"When speech processor module 180 and on-board power supply 216 are mounted on tray 324, they are electrically connected to each other.\",\n \"In the embodiment shown in FIGS.\",\n \"2 and 3, for example, such electrical connection is provided by tray 324 so that additional components need not be included in protective case 202, and additional steps beyond mounting speech processor 180 and power supply 216 are not necessary to attain an electrical connection.\",\n \"Specifically, wiring connects the power supply contacts (not shown) on tray 324 and the connector (not shown) on connector block 332 which mates with speech processor module 180.Such wiring may be integrated, for example, into platform 336 of tray 324, or may extend below platform 336.In the latter embodiment, tray 324 preferably does not rest in the bottom surface of base member 204; rather, it rests on support members to provide a space between platform 336 and base member 204 when tray 324 is secured to the base member.\",\n \"As one of ordinary skill in the art would appreciate, the type of electrical connection provided can vary depending on the particular application.\",\n \"For example, the pins and sockets used to establish the battery connection can be replaced with any other type of electrical connectors.\",\n \"Also, one pin 322 can provide both the positive and ground connections for transferring power to speech processor module 180.As noted, base member 204 and cover member 206 are attached to each other to provide a protective enclosure for speech processor module 180 and on-board power supply 216.Cover member 206 and base member 204 are configured also to provide the recipient or carer access the enclosure to install or remove speech processor module 180 and power supply 216.In the embodiment shown in FIGS.\",\n \"2 and 3, for example, cover member 206 is removable; that is, cover member 206 and base member 204 separate from each other to expose the interior of base member 204.It should be appreciated, however, that a portion or all of cover member 206 may be configured, for example, to rotate away from base member 204 to create an aperture through which speech processor module 180 and on-board power supply 216 can be passed.\",\n \"Such rotation can be provided, for example, with mechanical hinges.\",\n \"There are, of course, a myriad of other arrangements that may be implemented to provide the noted access.\",\n \"For example, one or more rotating, sliding, removable, or other types of doors, panels, sides, etc., may be implemented in either or both, cover member 206 and base member 204.Cover member 206 and base member 204 may be formed of any material or combination of materials suitable for the intended recipient and environment.\",\n \"For example, cover and base members 206, 204 may be formed of metallic material, ceramic material, polymeric material, composites or any combination thereof.\",\n \"In addition, cover and base members 206, 204 may be opaque, translucent, transparent, etc., to provide a desired view of a desired portion of the interior of protective case 202 from the recipient, carer or third party.\",\n \"In the exemplary embodiment shown in FIG.\",\n \"3, protective case 202 contains a gasket 302 to seal protective case 202 when cover member 206 is joined with base member 204.As noted, embodiments of protective case 202 protect components mounted therein from a variety of environmental elements such as fluids, dust, etc.\",\n \"Gasket 302 is appropriately configured and formed of the appropriate material to provide the desired degree of protection from at least the environmental elements of concern.\",\n \"In the embodiment shown in FIGS.\",\n \"2 and 3, gasket 302 is shaped to be disposed between the mating surfaces of cover member 206 and base member 204 when the cover and base are brought together to form protective case 202.Accordingly, gasket 302 takes the shape of the perimeter of protective case 202 at the location that the cover and base members meet.\",\n \"In one particular embodiment, gasket 302 provides additional protection.\",\n \"As shown in FIGS.\",\n \"2 and 3, gasket 302 includes a contiguous sheath 334 of fluid-impermeable, resiliently flexible material extending across the interior of the gasket.\",\n \"When installed in protective case 202, this embodiment of gasket 302 seals with the perimeter wall of base member 204.This causes sheath 334 to cover speech processor module 180 and power supply 216 mounted in base member 204.Thus, in addition to preventing ingress of at least selected environmental elements, gasket 302 and sheath 334 also protect components from those environmental elements which manage to penetrate protective casing 202.Sheath 334 can be manufactured from polymeric, elastomeric or other suitable materials.\",\n \"In one embodiment, sheath 334 is transparent.\",\n \"Protective case 202 comprises a fixation device to removably secure cover member 206 to base member 204.In the embodiment illustrated in FIGS.\",\n \"2 and 3, such a fixation device comprises a combination of an appropriately located screw and threaded hole.\",\n \"Specifically, sheath 334 has an orifice 304 formed therein that is adapted to allow passage of a threaded shaft of fixation screw 214 through sheath 334.Similarly, cover member 206 has an orifice 308 adapted to allow passage of the threaded shaft of screw 214.When cover member 206 and sheath 334 are assembled with based member 204, orifice 308 and orifice 304 are aligned with each other.\",\n \"Screw 214 may then pass through orifice 308 in cover member 206, and orifice 304 in sheath 334 to threadingly engage a threaded hole 310 of a post 312 on tray 324.It should be appreciated by those of ordinary skill in the art that the implemented fixation device should not degrade the integrity of the protective features implemented in protective case 202.For example, in the above embodiment in which a fixation screw 214 is implemented, at the location of screw 214, an elastomeric grommet 314 is provided to help prevent ingress of fluid into the protective case at the site of screw 214.Additionally washers, o-rings and the like may also be used as appropriate.\",\n \"External component system 200 also comprises a one-piece headpiece 208 communicably coupled to speech processor module 180 via a cable 210.As noted, headpiece 208 comprises the above-noted external transmitter unit 106 including external coil 108, and magnet 110 mounted in a housing 220 that provides the same or similar protection of its components as protective case 202.In accordance with one embodiment of the present invention, headpiece 208 also comprises a second microphone 212 mounted thereon which is operable when speech processor module 180 is installed in protective case 202.When speech processor module 180 is installed in protective case 202, microphone 186 cannot be used since it will be enclosed with protective case 202.As such, external component system 200 provides an alternate or replacement microphone 212, referred to as external microphone 212.Protective case 202 has an additional orifice (not shown) provided in base member 204 to permit cable 210 to be inserted into the case.\",\n \"Cable 210 extends from headpiece 208 into case 202 to mate with connector 188 of speech processor module 180.The orifice may be sealed, for example, by a grommet 316 provided around the distal end of cable 210.For example, in one embodiment, grommet 316 and orifice are constructed and arranged to prevent water from entering protective case 202.As noted, protective case 202 provides protection for speech processor module 180 and on-board power supply 216.In the embodiments described above, such protection includes protecting the components from ingress of fluid, dust or other particulates such as airborne fumes.\",\n \"In other embodiments, protective case 202 is capable of providing protection against electromagnetic interference (EMI).\",\n \"In such embodiments, the interior surfaces of cover member 206 and base member 204 are coated with a conformal EMI coating such as that used in cellular phones, computer systems and other electronic devices that emit or are sensitive to electromagnetic radiation.\",\n \"In addition, in such embodiments gasket 302 is an EMI gasket suitable for preventing EMI from escaping through the joined surfaces of cover member 206 and base member 204.In other embodiments, protective case 202 protects the components mounted therein from vibration and/or shock.\",\n \"In such embodiments, tray 324 may be suspended on a shock- and vibration-absorbing material or elements such as resilient posts or extensions disposed in or integrated with base member 204.In addition, the dimensions of tray 324 may be somewhat less than the

methods of making and using a wide swath concrete screed that doesn't require mechanical vibration.","Description of Related Art Wet concrete generally arrives on-site in a concrete truck for pouring into the forms to define the desired level when the concrete dries.","When the concrete is poured from the chute of the concrete truck the result is generally mounds of wet concrete—often called mud or slurry—piled above the level defined by the top edges of the forms.","The slurry must be promptly leveled as it is poured, before it hardens or sets.","Typically, the leveling is performed by a screed—a specialized tool that traverses the forms.","Smaller pours such as a sidewalk can be leveled with a hand screed that one or more workers drag along the forms to level the mounds of wet concrete.","It is not feasible to use hand screeds for larger pours such as parking lots, road surfaces, the floors of buildings or other such large, flat concrete surfaces.","The weight of the concrete being pulled off is generally too great for workers to use hand screeds.","Larger concrete projects must be poured in strips that may be ten to twenty feet wide, but can even be thirty or more feet wide.","Conventional mechanized concrete screeds are used to level the strips of concrete.","One such type of conventional mechanized screed involves the use of a vibrating screed.","A small gasoline engine is mounted on the screed with a rotating offset weight designed to impart vibration to the screed as it is dragged across the wet mud.","Some conventional vibrating screed implementations require one or more workers just outside the forms to push and guide the screed along the top of the forms as the engine vibrates the screed.","The vibration is required to prevent small pebbles from momentarily catching on the front edge of the screed and dragging small holes in the surface of the slurry before the pebble finally passes under the screed.","The vibration aids in pushing the small pebbles down into the slurry, allowing the conventional vibrating screed to pass over the pebbles with minimal perturbation to the surface of the wet concrete.","A gasoline or diesel engine is required for this conventional solution, thus requiring one or more workers to attend to the engine as the device is started and stopped many times during the course of a day's pouring.","Due to the dirt and dust present at the work site it can be difficult to keep the conventional vibrating screed from breaking down during a pour, often necessitating emergency repairs to keep pouring while concrete trucks are standing by ready to unload their wet concrete.","Published U.S. Patent Application 2009/0092444A1 to Schoen (hereinafter “Schoen”) describes a conventional wide swath motorized screeds.","The Schoen screed features a screed mechanism attached to a skid loader that a worker operates to pull the mounds of wet concrete and create a level surface.","Another implementation of a conventional mechanical screed involves attaching a conventional vibrating screed to a front end loader or skid loader.","Mounting a conventional vibrating screed on a front end loader eliminates the need for concrete workers to push the screed along as it vibrates.","SUMMARY Embodiments disclosed herein address drawbacks of the conventional mechanical concrete screeds.","The

the swath, and an end form may be positioned between the longitudinal forms, defining the end of the swath.","Once the wet concrete slurry is poured within the longitudinal forms—generally, one truckload at a time—the leveling is performed by running a screed along the top of the longitudinal forms to smooth the swath of concrete between the forms.","The term “leveling” is used to describe the smoothing process using a screed.","The result of “leveling” the wet concrete slurry with a screed produces a relatively flat surface between the forms.","This flat concrete surface that results from leveling with a screed may, or may not, be level with respect to the earth's surface.","For example, the floors of buildings, parking lots and other concrete surfaces are often designed to have a slight degree of slope in order to allow water to run off.","Concrete surfaces are often poured to slope between ⅛ inch per foot to up to ⅝ inch per foot, with ¼ inch per foot being a common value.","Therefore, the term “leveling” as it is used herein implies that the surface of the concrete is smoothed to conform to a flat surface between the top edges of the forms, and may include a built in amount of slope rather than being perfectly level relative to the earth's surface.","That is, leveling wet concrete means to smooth the surface to be relatively flat across the tops of the two forms the concrete was poured into.","In situations where multiple swaths are being poured to form a wide expanse of concrete, it is often the case that the previously poured swath of concrete, now hardened, is used in place of the forms on one side of the next swath to be poured.","In such cases where a swath is being poured beside another, previously poured swatch, a spacer may be used to compensate for the level of freshly screeded concrete being slightly lower than the level of the underside of the screed, as discussed further in conjunction with FIG.","5.Motorized screeds—that is, a screed mechanism attached to a skid loader or other motorized vehicle—are often used to save time and labor in pouring swaths of concrete.","The present inventor recognized several drawbacks inherent in the designs of conventional mechanized screeds, for example, the Schoen screed of Published U.S. Patent Application 20090092444A1.One major drawback of it is that the front end loader of the conventional Schoen screed must be driven within the forms directly ahead of the wet concrete being leveled.","Nearly all concrete is poured over one or more layers of iron rebar lying on a surface of sand which acts to strengthen and reinforce the concrete.","Using the conventional Schoen motorized screed requires the skid loader to be driven over the rebar, pushing it into the layer of sand beneath the concrete and often causing deformities in the rebar.","This would render the rebar useless unless remedied before the concrete dries.","Thus, workers must be positioned between the conventional Schoen screed and the wet concrete being leveled to pull the rebar out of the sand.","Another disadvantage of the Schoen device that the present inventor recognized involves the end form for the pour.","An end form is the form at the end of the swath being poured, for example, to define the edge of a building pad or parking lot.","A skid loader cannot be driven over the end form without destroying it.","So, in order to use the Schoen device the end form must be assembled as soon as the front end loader of the conventional Schoen screed passes that point.","Alternatively, some sort of makeshift removable bridge or ramps could be constructed over the end form, allowing the front end loader of the conventional Schoen screed to be driven up over the end forms without damaging them.","These, and other drawbacks of the conventional screeds recognized by the present inventor, are overcome by various embodiments disclosed herein.","FIG.","1 is an oblique view of a wide swath offset concrete screed 100 according to various embodiments disclosed herein.","The wide swath concrete screed is mounted on a motorized vehicle 101 such as a skid loader, an extension loader, a front end loader, a tractor, a backhoe, a truck, a tractor, a tracked loader, or other such motorized vehicle.","The wheeled vehicle 101 has a liftable mechanical arm 119 of sufficient strength to hold the screed assembly with the capability of lifting it up and down.","The offset wide swath concrete screed 100 affords the advantage of being mounted to the side of motorized vehicle 101—that is, the concrete screed 100 is mounted such that the screed bar 107 is offset to the side of the motorized vehicle 101.To be considered “offset” the screed bar 107 must be positioned outside the wheels (or track, if a tracked vehicle) in the direction of an axel of the motorized vehicle 101.This offset mounting configuration allows the motorized vehicle 101 to be driven along the outside of concrete forms 197.This is a significant advantage over conventional mechanized screeds that drive within the concrete forms.","In this way the various embodiments disclosed herein do not push the rebar 199 into the sand as the concrete is being screeded.","Moreover, the various embodiments of the wide swath concrete screed disclosed herein are able to screed concrete right to the end of the longitudinal forms without damaging the end form.","Various embodiments of screeds disclosed herein are also capable of being mounted directly in front of the motorized vehicle 101 for those situations when there is insufficient room alongside the forms 197 to drive the motorized vehicle 101, e.g., when the last swath being poured is up against a fence, wall or building.","The liftable arm 119 of the motorized vehicle 101 allows a user to lift the concrete screed 100 up and down as needed during the pour.","Since the concrete screed 100 may weigh 300 pounds or more, with an outer end that extends beyond the motorized vehicle 101 by several feet more the width of the longitudinal forms, the liftable arm 119 must have sufficient strength to withstand the rotational force due to the weight of the concrete screed 100 hanging out to the side.","The offset concrete screed 100 includes a connection mechanism 143 or structure for attaching the cross support bar 103 to the motorized vehicle 101.In some embodiments the connection mechanism 143 includes two metal plates bolted together to clamp down on the cross support bar 103 and hold it securely to the liftable arm 119.In some embodiments the connection mechanism 143 includes U-bolts, or metal cables, to secure the cross support bar 103 to the liftable arm 119.In other embodiments the connection mechanism 143 includes an adapter to fasten the cross support bar 103 to a fork lift attachment, or a three-point hitch, of the liftable arm 119.In yet other embodiments the connection mechanism 143 attaches to a hydraulic cylinder to affix the cross support bar 103 to the motorized vehicle 101.Regardless of the configuration, the various embodiments of the connection mechanism 143 includes structural means for attaching the cross support bar 103 to the liftable arm 119 of the motorized vehicle 101, either in a stationary position or in a manner capable of hinging.","A screed bar 107 is configured to pull the mounds of wet concrete slurry deposited within the forms by a concrete truck.","In this way the slurry is leveled during a pour by the action of the motorized vehicle driving back and forth on the outside of forms 197.The screed bar 107 is pulled by lateral support bars 105, which in turn, are connected to cross support bar 103.The motorized vehicle 101 may be positioned to push the cross support bar 103 in the direction of screeding movement 173, as shown in FIG.","1.Alternatively, the motorized vehicle 101 may be positioned on the other side of the cross support bar 103 so as to pull the cross support bar 103 in the direction of movement 173.In either case, the screed bar 107 is dragged behind the cross support bar 103 as the wet concrete slurry is being screeded.","This dragging motion prevents the screed bar 107 from jamming down or catching on the forms as it is moved along.","The screed bar 107 is of sufficient length for both ends to rest on the longitudinal forms 197.Typically the screed bar 107 is slightly wider than the distance between the longitudinal forms 197 so that the screed bar 107 extends beyond the longitudinal forms 197 by a few inches.","In a typical implementation the screed bar 107 may be from 6 to 24 inches longer than the distance between the longitudinal forms 197.In other implementations the screed bar 107 may be any length from the same width as the outer width of the forms up to ten or more feet wider than the width of the forms.","There is no set limit as to how much wider the screed bar 107 is as compared to the width of the forms 197.However, since workers often walk or stand just outside the forms it tends to be more safe and convenient for the width of the screed bar 107 to extend beyond the forms by no more than a few inches on each side.","For example, in some embodiments the screed bar 107 is of a sufficient length so that it extends beyond the forms by 8-10 inches on either side to keep the screed from falling inside the forms 197.Depending upon the application, the swatch of concrete may be of any given width.","For some uses the width of the concrete swath is not important.","For example, a large expanse of concrete such as a parking lot may sometimes be poured in strips or swaths of any width, up to the maximum width, that is desired by the prime contractor or suitable for the situation.","However, some applications (and some builders) require that the concrete be poured in a specific width swatch, e.g., 12 feet, 15 feet, 20 feet, 25 feet, 30 feet, or other such swath widths.","To accommodate these specific swath widths, the concrete screed 100 may be equipped with various lengths of screed bar 107.In some embodiments, the length of the screed bar 107 is fixed, and bars of various lengths are swapped out to accommodate the required swath width.","Other embodiments of the screed bar 107 are configured so that the length of the screed bar 107 may be adjusted to suit the distance between the forms 197 or other parameters.","This may be achieved by providing a telescoping screed bar 107, or by providing removable sections of the screed bar 107 which may be swapped out to achieve the desired length.","The screed bar 107 is held by two or more lateral support bars 105, which in turn, are connected to a cross support bar 103.To smooth out the mounds of wet concrete the motorized vehicle 101 is typically positioned to push the cross support bar 103.However, the cross support bar 103 is configured to pull the screed bar 107 along, dragging the wet concrete to a level format.","This pulling action aids in preventing the screed bar 107 from gouging into the longitudinal forms, thus making the screed bar 107 operate more smoothly as the wet concrete is being leveled.","FIG.","2 is an oblique view depicting wide swath offset concrete screed 100 in use as wet concrete is being poured.","The figure shows the point in time when the wet concrete from one truck has already been leveled out, the screed bar 107 has been lifted up out of the way, and motorized vehicle of 101 (not shown) of the concrete screed 100 is backed up so as to allow another truckload of wet concrete to be poured.","As shown in FIG.","2 the lateral support bar 105 is attached to the cross support bar 103 by a hinge assembly 109 configured to hinge upward as the screed bar 107 comes to rest on forms 197.The hinge assembly 109 prevents the screed bar 107 from hinging downward more than a predetermined amount, in order to lift the screed bar 107 off the forms as shown in FIG.","2.The predetermined amount—defined as the support bar angle—is measured at the point where the motorized vehicle 101's liftable arm 119 has been lowered such that the screed bar 107 just touches the forms 197.That is, the support bar angle is the angle between the axis of rotation of the hinge assembly 109 and the bottom front edge of the screed bar 107 when it is lowered to the point of just touching the forms 197.It should be clear from this that the the support bar angle does not depend upon the shape of the lateral support bar 105.At this point, if the cross support bar 103 is raised it will lift the screed bar 107 up since the hinge assembly 109 won't hinge downward past the support bar angle.","On the other hand, if the cross support bar 103 is instead lowered the hinge assembly 109 will hinge upward since the screed bar 107 is resting on the forms 197.Various embodiments are configured so the lateral support bar 105 hangs downward at a support bar angle of from 1 degree to as much as 60 degrees, or any angle within these limits, with a hang angle of 15 degrees being typical.","The lower limit of the support bar angle, 1 degrees, is determined by the distance between the axis of rotation of the hinge assembly 109 and the bottom surface of the cross support bar 103, and depends on the length of the lateral support bar 105.FIG.","3 is a close up view depicting details of one embodiment of the hinge assembly 109 between the lateral support bar 105 and the cross support bar 103.Other embodiments may use like types of structures configured to provide a hinging action such as an ordinary hinge, a rocker arm assembly, a trough holding the ends of lateral support bars 105 and flexible cable controlling the maximum hinge angle or support bar angle, a ball joint, or other like types of hinging structures.","The hinge assembly 109 connects the lateral support bar 105 to the cross support bar 103.The hinge assembly 109 allows the lateral support bar 105, and in turn the screed bar 107, to hinge upward as the device is lowered onto the longitudinal forms 199.As discussed above, the hinge assemblies 109 prevent the lateral support bars 105, and in turn the cross support bar 103, from hinging downward by more than a predetermined amount, defined as the support bar angle.","In this way the motorized vehicle 101 can lift the screed bar 107 up in the air.","The conventional Schoen screed of Published U.S. Patent Application 20090092444A1 features a mounting pocket 62 that prevents arm 48 from rotating too far downward.","Such a pocket/arm assembly could be used with embodiments disclosed herein as a hinging mechanism.","However, the present inventor recognized certain drawbacks with the Schoen pocket/arm assembly.","Namely, the pocket tends to retain wet concrete and small pebbles during the course of a working day.","This, in turn, makes the pocket difficult to clean upon completion of a work day.","At the end of each day, and perhaps even during the course of the day, the bar 48 must be rotated upward out of pocket 62 in order to clean out all the accumulated concrete and pebbles.","If the pocket 62 of the Schoen device is allowed to dry overnight without being thoroughly cleaned it will sometimes freeze in place as the bits of remaining concrete dry and harden.","The Schoen device can also freeze up while it is being used if a small pebble or bit of concrete becomes lodged between the bar 48 and pocket 62.The hinge assembly 109 overcomes these drawbacks since it is a more open design which does not tend to accumulate pebbles and wet concrete.","The hinge assembly 109 is easier to clean with a hose and water since there is no pocket for pebbles and wet concrete to gather in during the course of a day.","In various embodiments of the offset concrete screed 100, the hinge assembly 109 is rotatably connected to cross support bar 103 by a pin 121.By “rotatably connected” it is meant that the hinge assembly is connected in a manner that allows it to rotate, or hinge, about an axis.","In some implementations the pin 121 passes through, or is otherwise connected to, a pin holder bar 123.In other embodiments the pin 121 is connected directly to the cross support bar 103.The pin 121 may be a bolt of sufficient diameter (e.g., ⅜ to 1 inch) for supporting the weight of the lateral support bars 105 and screed bar 107.The bolt may be kept in place with a nut, or two nuts tightened against each other, and washers to aid in preventing wear on the bolt and hinge assembly 109.In other implementations a hinge pin, a metal rod, or other like type of pin may be used as the pin 121.In some embodiments one or more springs 167 are connected to some point on the support bar assembly to provide more downward force than the weight of the screed bar 107.The additional downward force aids in preventing the screed bar from riding up over the wet concrete slurry.","Typically, the springs 167 are configured to be removable so that weaker or stronger springs—or multiple springs—can be attached, as needed.","In this way the user is able to adjust the downward force to accommodate the conditions of the pour.","Some embodiments use compression springs to push downward on the support bar assembly.","In other embodiments leaf springs are used to provide the downward force.","The hinge assembly 109 is typically configured so that it comes to rest against cross support bar 103 when the offset concrete screed 100 is raised up in the air.","The hinge assembly 109 hinges upward in response to the concrete screed 100 being lowered so that the screed bar 107 rests on forms 197.This allows the screed bar 107 to ride along the top of the forms 197 without damaging the forms.","The hinging action also allows the screed bar 107 to ride up over an overly large mound of wet concrete to avoid putting too much horizontal strain on the screed bar 107 and concrete screed 100.If the screed bar 107 rides up over an overly large mound of wet concrete the user can simply raise the offset concrete screed 100 up in the air, back up the motorized vehicle 101, and take one or more additional passes at smoothing the large mound of wet concrete.","Since embodiments of the offset concrete screed 100 allow the motorized vehicle 101 to be driven off to the side rather than over the rebar, the user can efficiently make several passes without need to have workers reposition to rebar after each pass, as is required for conventional motorized screed devices.","FIG.","4 depicts the wide swath concrete screed 100 being used to level the wet concrete slurry 193 using a previously poured swath of concrete 195 in lieu of a form on one side.","In pouring large expanses of concrete for a parking lot or building pad it is often the case that the swaths are poured side by side with the previous day's swath acting as a form on one side of the current pour.","The very first swath poured requires a form 197 to be set up on each side of the swath to be poured.","For each subsequent swath poured after the previous swath has hardened (e.g., a day or more later) only one form 197 needs to be erected.","The previously poured swath 195, now hardened, acts as a form on the other side to contain the newly poured wet concrete slurry 193.One issue with using a previously poured swath in lieu of a form is that the process or screeding wet concrete results in a screeding process delta in which the level of the concrete is slightly lower than the level of the forms (or the form and the previously poured swath being used as a form).","For example, a screeded concrete surface may end up ¼ inch or so lower than the forms on either side—that is, have a screeding process delta of ¼ inch or so.","This is because the wet concrete slurry contains small pebbles and gravel in it.","The screeding process delta results because the screed bar 107 tends to push some of the small pebbles and gravel in front of it, causing the screeded surface of the wet concrete slurry to be slightly lower than the bottom surface of screed bar 107, e.g., ¼ inch or so lower.","This can be somewhat troublesome if the concrete is being poured in long swaths alongside a previously poured swath—now hardened—from the previous day.","If the screeding process delta was not compensated for and the form 197 was erected to be level with the previously poured swath, each newly poured swath would end up being ¼ inch or so lower than the previously poured swath beside it.","If a number of swaths were poured this way the result would be that each swath would be ¼ inch or so lower due to the screeding process delta of each swath.","In order to avoid this, it is desirable to provide forms 197 for the new swath to be poured that are at a level slightly higher than the previously poured swath to its side by an amount equal to the anticipated screeding process delta.","The slightly higher level of the form 197 compensates for the lower level of finished concrete due to the screed bar 107 pushing small pebbles and gravel in front of it.","However, if the previously poured swath (which has hardened) is being used as one of the forms 197 then it is not possible to adjust the height of the previously poured swath to compensate for the screeding process delta.","To this end, various embodiments use a screed bar spacer affixed to the bottom of screed bar 107 on the side of the previously poured swath in conjunction with the form 197 being constructed slightly higher than the level of the previously poured swath.","FIG.","4 also depicts a screed bar extension 135.The cross section of the screed bar extension 135 is typically the same as the screed bar 107, with a slightly smaller cross-sectional portion that fits into the end of the screed bar 107.One or more holes 139 may be provided for bolts 141 used to secure the screed bar extension 135 to the screed bar 107.The bolts 141 pass through holes 139 and tighten into threaded holes 137.FIG.","4 also depicts the wide swath concrete screed equipped with a scrape auger 181.The scrape auger 181 acts to push excess wet slurry concrete to one side or the other so as to aid in preventing too much wet slurry concrete from building up and pouring over the top of screed bar 107.Typically, the lower edge of the scrape auger 181 is positioned slightly above the lower edge of screed bar 107, e.g., one to three inches, but may be positioned as little as ¼ inch to as much as one foot above the lower edge of screed bar 107.The scrape auger 181 may either be affixed to the cross support bar 103 or may be affixed to lateral support bars 105 by connection points 179.Typically, connection points 179 have a bearing or greased sleeve to reduce the mechanical friction as the auger 181 rotates.","The auger 181 is rotationally powered by a power unit 183.The power unit 183 may be similar to power unit 185 depicted in FIG.","11B.","Power unit 183 may be implemented in various forms, including for example, a gas or diesel engine, an electric motor, a hydraulic motor, a rotating shaft connected to the power take-off of the motorized vehicle, a rotating linkage connected to the engine of the motorized vehicle, or other like type of power unit known to those of ordinary skill in the art.","The power unit 183 may either be connected to the cross support bar 103, or in other implementations, may be connected to one or more of the lateral support bars 105.The power unit 183 may be controlled by a user to controllably rotate the auger 181 at varying speeds.","The auger 181 may be rotated in one direction to push the wet concrete slurry towards the motorized vehicle 101, and may be controlled to rotate in the opposite direction to push the wet concrete slurry away from the motorized vehicle 101.FIG.","5 depicts embodiments 500 and 550 of an optional screed bar spacer and subgrade screeder 147 attachments that may be affixed to the screed bar.","As shown in the figure, the screed bar spacer 125 is affixed to the end of the screed bar 107 resting on a previously poured concrete surface 195 to compensate for the screeding process delta.","The screed bar spacer 125 is a removable attachment with a predetermined thickness that compensates for the level of freshly screeded concrete being slightly lower than the level of the underside of the screed bar 107 due to small pebbles and gravel being pushed in front of screed bar 107 during the screeding process.","A user simply taps the screed bar spacer 125 into position within the screed bar 107, and it is held in place by friction.","To remove the screed bar spacer 125, the user merely taps it back out.","The screed bar spacer 125 is held to the bottom side of screed bar 107 on the end that rides across the swath of previously poured, hardened concrete.","Since the level of the freshly screeded concrete will be lower by a slight amount than the bottom of the screed bar 107 due to the screeding process delta, the screed bar spacer 125 allows the screed bar 107 to pass over the newly poured concrete at a level slightly higher than the desired level of the finished concrete surface to compensate for the screeding process delta.","In this way, the newly screeded concrete will end up at approximately the same level as the previously poured concrete swath adjacent to it.","The wide swath offset concrete screed 100 may be provisioned with screed bar spacers 125 of various thicknesses, depending upon the anticipated amount of screeding process delta—that is, the amount that the newly poured concrete is anticipated to be lower.","The anticipated amount of screeding process delta depends upon the characteristics of the wet concrete slurry such as the size of the pebbles and gravel in the wet concrete slurry, how wet the concrete slurry is, the temperature of the wet concrete slurry, etc.","Since a given contractor may order wet concrete slurry many times from the same concrete supplier, the contractor will generally get a feel for the amount of screeding process delta to expect from a particular concrete provider for a given grade of concrete.","A screed bar spacer 125 for use with the various embodiments may have a predetermined thickness of as little as 1/16 inch or as much as ¾ inch, or any value in between, depending upon the characteristics of the wet concrete slurry resulting in screeding process delta.","A typical thickness for a slab of concrete 8 inches thick is ¼ inch.","In various embodiments the bottom side of the screed bar spacer 125 is smooth with rounded corners in order to push the pebbles and gravel of the wet concrete slurry underneath it during the screeding process.","This aids in preventing the pebbles and gravel from scraping along the surface of the wet concrete slurry before they pass beneath the screed bar spacer 125.In addition the screed bar spacer 125 is configured to be smooth with rounded corners aids to avoid gouging or scoring the concrete surface that it rests and slides upon.","FIG.","5 depicts another screed bar spacer embodiment—the screed bar spacer 127 which is configured with a wheel that rolls along the previously poured concrete surface 195.The screed bar spacer 127 is particularly useful when the previously poured concrete 195 has not yet hardened sufficiently to avoid scoring the surface.","The screed bar spacer 127 slides into screed bar 107, and is tightened into place with a compression bolt 133.Moreover, the screed bar spacer 127 may be configured to be adjustable by providing an elongated slot either for bolt 129 or for a bolt at point 131.FIG.","5 also depicts a subgrade screeder attachment 147.To preparing a pour site the contractor generally deposits gravel, sand or pebbles, or some other subgrade material, between the longitudinal forms 197.It is important to have a uniformly flat, level subgrade surface to pour the wet concrete slurry on, in order to ensure that the resulting concrete pad is of a uniform thickness.","According to conventional methods, the subgrade material is graded and leveled by hand with shovels or rakes.","These conventional methods of preparing the subgrade are quite a labor intensive and must be performed prior to pouring the concrete.","It generally takes at least a couple—or even several—manual laborers working to smooth and level the subgrade material by hand, and it is nearly impossible to create a uniformly flat, level subgrade surface.","The embodiments disclosed herein overcome aid in cutting down the manual labor required to prepare the subgrade materials by hand, while at the same time drastically increasing the precision of the subgrade leveling process.","The subgrade screeder attachment 147 depicted in FIG.","5 attaches to the screed bar 107 using one or more bolts 149.Alternatively, the subgrade screeder attachment 147 may be affixed to the screed bar 107 using pins, clamps, cables, chains, or other like type of structures for affixing the subgrade screeder attachment 147 in place on the screed bar 107.In other embodiments the subgrade screeder attachment 147 is attached to the screed bar 107 with a hinge mechanism so that it can be hinged upward out of the way when not in use.","The depth that the subgrade screeder attachment 147 extends below the lower level of screed bar 107 is adjustable in order to equal the desired thickness of the concrete pad being poured.","In the embodiment depicted in FIG.","5 there are a series of holes that allow the subgrade screeder attachment 147 to be set at various depths, thus creating concrete pads of various thicknesses.","In other embodiments the subgrade screeder attachment 147 has an elongated hole, or slot, to allow adjustment up and down to create various thickness of a concrete pad.","Typically, the width of the subgrade screeder attachment 147 is slightly narrower than the width of the longitudinal forms 197, for example, one to six inches narrower.","The screeder attachment 147 may be provided in multiple pieces so as to easily vary the width to accommodate the width of the longitudinal forms 197.The subgrade screeder attachment 147 is typically made of metal.","Aluminum generally provides sufficient strength, and is advantageously lightweight.","However, other implementations of the subgrade screeder attachment 147 may be made of iron, steel, or other like metals.","In some embodiments the lower edge of the subgrade screeder attachment 147 may be curved slightly in the direction of screeding movement 173.The slight curve tends to cut into the loose gravel, sand or pebbles typically used as subgrade material, thus pulling the subgrade screeder attachment 147 slightly downward to create a smooth, level subgrade surface.","In various embodiments the curved portion of the lower edge of the subgrade screeder attachment 147 is angled from as little as 15 degrees to as much as 90 degrees, relative to vertical.","In other embodiments the lower edge of the subgrade screeder attachment 147 is squared off straight, rather than having a slight curve as shown in FIG.","5.FIG.","6 depicts the wide swath offset concrete screed 100 in a raised position.","In some instances the area just outside the forms and just beyond the end of the swath of concrete being poured may have an obstacle such as a fence or building, or otherwise be inaccessible.","When this occurs it may not be possible to drive the motorized vehicle 101 very far beyond the end of the swath of concrete.","In such situations it is useful to be able to lift the concrete screed 100 high enough to permit a concrete truck to back up close enough to unload the wet concrete beneath the raised screed.","Various embodiments of the concrete screed 100 can be raise high enough to permit wet concrete to be unloaded beneath it, as shown in FIG.","6.For example, depending upon the type of motorized vehicle 101 being used, the wide swath offset concrete screed 100 can be raised to a level of fifteen feet or more.","For embodiments using an extension loader as the motorized vehicle 101 as depicted in FIG.","6 the offset concrete screed 100 can be raised to over twelve feet.","This is sufficient height to allow a concrete truck to back up and deliver its load of wet concrete slurry under the offset concrete screed 100.Other embodiments may raise the concrete screed 100 even higher, for example, for clearance beneath the screed bar 107 of 15 feet or even more, depending upon how far the liftable arm 119 of the motorized vehicle 101 is able to extend or rise in the air.","As the liftable arm 119 is lowered it is desirable not to slam it into the lateral forms 197.To aid in this some embodiments include a flow restrictor 145 in the hydraulic line to controllably constrict the flow of hydraulic fluid.","The flow restrictor 145 tends to slow down the upward and downward movement of the liftable arm 119, making it easier for a user to ease the liftable arm 119 into position as it is raised and lowered during the screeding process.","FIG.","7 depicts a lateral support bar 105 configured to have a slight amount of curve at point 175.In various embodiments it is desirable for the underside of screed bar 105 to lay relatively flat on the wet concrete slurry and the longitudinal forms 197.Having the underside of screed bar 105 flat aids in keeping it from riding up over mounds of wet concrete slurry as it is pulled along, or gouging into the wet concrete.","Further, the flat underside as it is drawn over the wet concrete slurry provides a smoothing effect that helps to produce a smooth, level surface of the finished concrete.","At the same time it is desirable to keep the cross support bar 103 several inches above the forms 197 to keep it from catching on the forms 197 and causing perturbations in the smooth surface of the concrete.","To achieve this—having the underside of screed bar 105 flat while the cross support bar 103 passes several inches above the forms 197—various embodiments of the lateral support bars 105 are configured to have a slight amount of curve.","In some embodiments the lateral support bars 105 are gradually curved along their entire length.","In other embodiments, the lateral support bars 105 are curved at a particular point, for example, at point 175 as depicted in FIG.","7.In yet other embodiments, the lateral support bars 105 are angled at a particular point rather than being gradually curved (e.g., a sharp curve).","In all of these embodiments the lateral support bars 105 are said to be curved by a lateral support bar curve 177.In various implementations the lateral support bar curve 177 may vary from as little as 1 degree to as much as 30 degrees, and may be any value in between these two extremes.","A typical value for the lateral support bar curve 177 is 4 degrees.","In some embodiments the lateral support bars 105 are approximately four feet long.","However, the length may be varied depending upon the requirements of the pour and the situation in which it is to be used to be as short as one foot or as long as twelve feet.","Using shorter lateral support bars 105 will result in the cross support bar 103 being positioned closer to the forms 197.Using longer lateral support bars 105 will result in more downward rotational force on the cross support bar 103 due to the increased leverage.","Therefore, in various embodiments the lateral support bars 105 are generally kept within three to six feet, with four feet being a typical length embodiment.","FIG.","8 is a flowchart depicting the use of the concrete screed 100 according to various embodiments of the invention.","Reference is made to the previous figures in the application, including various reference numbers shown in the figures.","The method begins at block 801 and proceeds to block 803 where the user provides a cross support bar 103.The cross support bar 103 is typically connected to the liftable arm 119 of a motorized vehicle 101.The method proceeds to block 803 for attaching the lateral support bars 105 to the cross support bar 103.This is generally done using hinge assemblies 109.In some embodiments, however, the lateral support bars 105 may be fixedly connected to the cross support bar 103, with the lateral support bars 105 themselves being capable of hinging.","The lateral support bars 105 typically have a slight amount of bend in them, e.g., approximately four degrees—that is, 4°+/−10%.","In block 807 the screed bar 107 is connected to the lateral support bars 105.Typically, the screed bar 107 is fixedly attached to the lateral support bars 105.However, in some embodiments the screed bar 107 may be connected to the lateral support bars 105 in a manner that allows the screed bar 107 to have some play or movement relative to the lateral support bars 105, e.g., a hinging motion.","In block 809 it is determined whether the longitudinal forms 197 are wider apart than the length of the screed bar 107.If the screed bar 107 needs to be longer, the method proceeds along the “YES” path to bock 811 for attachment of one or more screed bar extensions 135 to the screed bar 107, and then proceeds to block 813.If the screed bar 107 is of sufficient length for the configuration of longitudinal forms 197 the method proceeds from block 809 along the “NO” path to block 813.In block 813 of FIG.","8 it is determined whether the wet concrete slurry is to be poured into forms on either side (e.g., for the first concrete swath to be poured), or a previously poured, now hardened, swath of concrete is to be used on one side of the pour in place of the longitudinal forms for that side.","If previously poured swath of concrete is to be used in place of the forms it may be the case that the screeding will result in a screeding process delta in which the level of the concrete is slightly lower than the level of the forms, as discussed previously in conjunction with FIG.","5.If a screeding process delta—that is, a level of the concrete surface slightly lower than the scree bar surface—is anticipated, the method proceeds from block 813 along the “YES” path to block 815 to attach a screed bar spacer 125 or 127.However, if no screed bar spacer is desired the method proceeds from block 813 along the “NO” path to block 817.In block 817 the user operates the motorized vehicle 101 to screed the wet concrete slurry to a desired degree of levelness.","During the screeding process it is sometimes the case that the screed bar 107 needs to be raised, for example, to back the motorized vehicle 101 up or to allow a concrete truck to deliver another load of concrete.","If, in block 819, it is determined that the screed bar 107 needs to be raised the method proceeds along the “YES” path to block 823 to raise the screed bar 107 (or lower it if it was previously raised).","The method then proceeds to block 821 to determine whether further screeding operations need to be performed.","If further screeding is to be done, the method proceeds back to block 817 along the “YES” path.","However, if the screeding is completed the method proceeds from block 821 along the “NO” path to block 825 where the method ends.","Various activities of the method disclosed herein may be included or excluded as described above, or maybe performed in a different order than the particular examples chosen to illustrate the embodiments.","For example, it may be the case that the screed bar extension may be attached to the screed bar (block 811) prior to attaching the screed bar to the lateral support bar (block 807).","Or it may be the case that the screed bar spacer may be attached to the screed bar (block 815) prior to attaching the screed bar to the lateral support bar (block 807).","The sequence of steps for performing the method of making and using a wide swath offset concrete screed according to the various embodiments disclosed herein may be altered in many other ways as well.","FIGS.","9-10 are oblique views depicting embodiments of an up-down offset concrete screed.","The present inventor recognized the difficulty of screeding concrete into certain tight spaces—for example, screeding into the corner formed by two buildings, or screeding right up against a building or a wall.","In such tight spaces it is desirable to be able to operate the screed as closely as possible up to the limiting obstruction.","The embodiments depicted in FIGS.","9-10 make it possible to screed into tight places with only a minimum of finish work to be done by hand.","The up-down offset concrete screed embodiment features two or more vertical support bars 151.The vertical support bars 151 are designed to move up and down, as needed, during the screeding operation.","For example, it may be that the surface outside the forms on which the motorized vehicle 101 is driving is unlevel or bumpy.","If the motorized vehicle 101 moves up or down as it is traveling along, the vertical support bars 151 can move down or up, as needed, so that the screed bar 107 may remain on the forms 197.In some instances, if there is too much wet concrete slurry 193 being pushed the screed bar 107 may ride up over the slurry, leaving an unlevel spot that will require further screeding on another pass.","Each vertical support bar 151 is enclosed by a support bar sleeve 153 that allows the vertical support bar 151 to move up and down.","The end of each vertical support bar 151 is larger than the passage dimensions of the support bar sleeve 153 to prevent the vertical support bar 151 from passing through it.","This allows the cross support bar 103 to lift up the vertical support bar 151 and accompanying screed bar 107.To aid in the up/down movement the support bar sleeves 153 have bearings on their inner surface, making it easier for the vertical support bars 151 to ride up and down with the lateral force of the concrete slurry pushing against them.","Alternatively, the support bar sleeves 153 may have small wheels or lubricant instead of bearings.","The vertical support bars 151 are rotatably attached to the screed bar 107 allowing the vertical support bars 151 to rotate about an axis, the axis being in the direction of screeding—that is, the axis of rotation is in the same direction as the direction of screeding (e.g., motorized vehicle movement), allowing the direction of rotation to be back and forth at a right angle to the direction of screeding.","Similarly, the support bar sleeves 153 are rotatably attached to the cross support bar 103.In this way, if the motorized vehicle 101 drives on an unlevel or bumpy spot causing the cross support bar 103 to raise up or dip relative to the screed bar 107, the vertical support bars 151 won't bind up if they raise or drop by different amounts.","In this way the screeding operation can continue smoothly even though the cross support bar 103 does not remain parallel with the screed bar 107.The vertical support bars 151 may be rotatably attached to the screed bar 107 by a tab 155 that is welded, bolted or otherwise affixed to the screed bar 107.The tab 155 has a pin or bolt configured to pass through a hole in the vertical support bar 151, thus allowing the vertical support bars 151 to rotate relative to the screed bar 107.In other embodiments (no shown) the tab 151 is affixed to the vertical support bar 151 and has a bolt or pin that passes through a hole in the screed bar 107.FIG.","10 depicts details of an embodiment for rotatably connecting the support bar sleeves 153 to the cross support bar 103.FIG.","10 is oblique cutaway view of an embodiment of the support bar sleeve 153 that rotatably attaches the support bar sleeve 153 to the cross support bar 103.In this embodiment the hinging mechanism is a bolt 157 that is welded, or otherwise attached, to the support bar sleeve 153 and passes through a hole 159 in the cross support bar 103.The bolt 157 allows the support bar sleeve 153 to rotate as needed relative to the the cross support bar 103.Other hinge mechanisms may be used in various implementations to connect the vertical support bars 151 to either the support bar 103 or to the screed bar 107, including for example, a hinge, a flexible cable, chain links affixed to each part, a shaft and bearings, a trough or slot that supports a shaft, or other like mechanisms known to those of ordinary skill in the art.","FIG.","11A depicts an embodiment of a vibrating float assembly configured to be pulled behind the screed bar 107.In typical implementations the vibrating float assembly is fairly lightweight, for example, weighing between five and twenty-five pounds.","However, either heavier or lighter implementations may be constructed, depending upon the dimensions and materials used in the vibrating float assembly itself, and the characteristics of the concrete slurry being floated.","Typically, two or more vibrating float assemblies are rotatably affixed to the screed bar 107.In some embodiments two or more points on the screed bar 107 serve as the points of rotation for the float assemblies to hinge, or rotate, downward onto the surface of the wet concrete slurry.","In other embodiments, as shown in FIG.","11B, the float assembly itself—in the form of a roller screed—rotates about an axis connected to screed bar 107.Turning again to FIG.","11A, some embodiments feature only one float affixed to the screed bar 107.The screed bar 107 generally is configured to extend beyond the outermost and innermost vibrating float assemblies by at least a few inches.","That way, the vibrating float assemblies ride solely on the wet concrete slurry and do not extend quite to the forms.","However, in some implementations, the vibrating float assemblies may be configured to be the same width as the screed bar 107 so the outermost portions of the vibrating float assemblies ride on the forms just as the screed bar 107 does.","Each vibrating float assembly has a float pan 161.The float pans 161 are constructed in various lengths, depending upon the length of the screed bar 107 to which they are attached.","The float pans 161 attached to a particular screed bar 107 do not all necessarily need to be the same length.","For example, a 17foot screed bar 107 for use on forms 197 that are 16 feet apart may have an 8 foot float pan 161 and a seven foot float pan 161 which are spaced 2 inches apart.","This would leave 5 inches of space between the outmost edges of the float pans 161 and the forms 197.The float pan 161 features a lip that is bent upwards the full length of the pan.","The bent lip may be from one to four inches wide.","In typical implementations the bent lip is approximately two inches wide and the overall width of the pan is approximately twelve inches.","The bent lip may be bent upwards from as little as 3 degrees to as much as 60 degrees.","In typical implementations, the bent lip may be bent upwards from 35 to 55 degrees, with 45 degrees being a common amount.","The flat bottom surface of the float pan 161 is generally configured to be wider than the bent lip portion, e.g., from 2 inches to 20 inches wide.","In typical implementations, the flat bottom portion is from six to twelve inches wide.","The float pan 161 may be constructed from a number of materials, including for example, aluminum, magnesium, steel, iron, wood, composite material, or the like.","Each float pan 161 has mounted upon it a vibrating mechanism—typically an off-balance vibrating electric motor.","The electric motor may either be wired to a power source back on the motorized vehicle such as the vehicle's battery, or may have a battery pack mounted in place with it on the float pan 161.The motor and battery pack are generally mounted towards the center of the float pan 161 to evenly distribute their weight across the wet concrete slurry.","Each float pan 161 is affixed to the screed bar 107 by one or more float hinge mechanisms.","The embodiment depicted in FIG.","11A has a float hinge mechanism features a U-shaped member that fits snuggly over the screed bar 107.In some embodiments the U-shaped member may bolt, screw or otherwise be attached to the screed bar 107 so as to be more firmly attached than friction would allow.","The hinge member 163 is rotatably connected to a hinge tab 165.The hinge tab 165 is affixed to the float bar 107 by welding, bolts, rivets, screws, or other ways of attaching materials together known to those of skill in the art.","The hinge member 163 is rotatably connected to a hinge tab 165 by a bolt or pin, allowing it to rotate in the direction 169.Typically, the float hinge mechanism is configured to allow the float pan to hinge downward from horizontal by a limited amount somewhat less than 30 degrees.","For example, in one embodiment the float pan can hinge downward an amount between 1 and 15 degrees—with an amount of downward hinging between 1 and 6 degrees being typical.","To measure it another way, the hinge mechanism allows the float pan to hinge downward from 1 to 4 inches, as measured by the distance the float bar 107 is raised above the level of the forms 197 before the float pan's rear edge begins to come off the surface of the wet concrete slurry.","In this way, the float pan will gently ride on top of the concrete slurry to a horizontal position as the screed bar 107 is lowered towards the forms 197.If the float pan is allowed to hinge down into too steep of an angle, it will gouge into the wet concrete slurry as the screed bar 107 is lowered.","FIG.","11B depicts an embodiment in which the float bar is in the form of a rotating float assembly, typically called a roller screed.","The roller screed 187 is manipulated back and forth to smooth the surface of the wet concrete slurry.","In various embodiments the direction of rotation at the point where the roller screed 187 meets the wet concrete slurry is in direction 171 towards the slurry yet to be smoothed,

Invention The present invention relates to a wide swath offset concrete screed for leveling poured concrete within a form, and more specifically systems and methods of making and using a wide swath concrete screed that doesn't require mechanical vibration.\",\n \"Description of Related Art Wet concrete generally arrives on-site in a concrete truck for pouring into the forms to define the desired level when the concrete dries.\",\n \"When the concrete is poured from the chute of the concrete truck the result is generally mounds of wet concrete—often called mud or slurry—piled above the level defined by the top edges of the forms.\",\n \"The slurry must be promptly leveled as it is poured, before it hardens or sets.\",\n \"Typically, the leveling is performed by a screed—a specialized tool that traverses the forms.\",\n \"Smaller pours such as a sidewalk can be leveled with a hand screed that one or more workers drag along the forms to level the mounds of wet concrete.\",\n \"It is not feasible to use hand screeds for larger pours such as parking lots, road surfaces, the floors of buildings or other such large, flat concrete surfaces.\",\n \"The weight of the concrete being pulled off is generally too great for workers to use hand screeds.\",\n \"Larger concrete projects must be poured in strips that may be ten to twenty feet wide, but can even be thirty or more feet wide.\",\n \"Conventional mechanized concrete screeds are used to level the strips of concrete.\",\n \"One such type of conventional mechanized screed involves the use of a vibrating screed.\",\n \"A small gasoline engine is mounted on the screed with a rotating offset weight designed to impart vibration to the screed as it is dragged across the wet mud.\",\n \"Some conventional vibrating screed implementations require one or more workers just outside the forms to push and guide the screed along the top of the forms as the engine vibrates the screed.\",\n \"The vibration is required to prevent small pebbles from momentarily catching on the front edge of the screed and dragging small holes in the surface of the slurry before the pebble finally passes under the screed.\",\n \"The vibration aids in pushing the small pebbles down into the slurry, allowing the conventional vibrating screed to pass over the pebbles with minimal perturbation to the surface of the wet concrete.\",\n \"A gasoline or diesel engine is required for this conventional solution, thus requiring one or more workers to attend to the engine as the device is started and stopped many times during the course of a day's pouring.\",\n \"Due to the dirt and dust present at the work site it can be difficult to keep the conventional vibrating screed from breaking down during a pour, often necessitating emergency repairs to keep pouring while concrete trucks are standing by ready to unload their wet concrete.\",\n \"Published U.S. Patent Application 2009/0092444A1 to Schoen (hereinafter “Schoen”) describes a conventional wide swath motorized screeds.\",\n \"The Schoen screed features a screed mechanism attached to a skid loader that a worker operates to pull the mounds of wet concrete and create a level surface.\",\n \"Another implementation of a conventional mechanical screed involves attaching a conventional vibrating screed to a front end loader or skid loader.\",\n \"Mounting a

FIG.\",\n \"11A depicts an embodiment of a vibrating float assembly; and FIG.\",\n \"11B depicts an embodiment of a rotating float assembly.\",\n \"DETAILED DESCRIPTION Typically, to pour a swath of concrete a pair of longitudinal forms is assembled at the desired level of the concrete.\",\n \"The longitudinal forms run along the sides of the swath, and an end form may be positioned between the longitudinal forms, defining the end of the swath.\",\n \"Once the wet concrete slurry is poured within the longitudinal forms—generally, one truckload at a time—the leveling is performed by running a screed along the top of the longitudinal forms to smooth the swath of concrete between the forms.\",\n \"The term “leveling” is used to describe the smoothing process using a screed.\",\n \"The result of “leveling” the wet concrete slurry with a screed produces a relatively flat surface between the forms.\",\n \"This flat concrete surface that results from leveling with a screed may, or may not, be level with respect to the earth's surface.\",\n \"For example, the floors of buildings, parking lots and other concrete surfaces are often designed to have a slight degree of slope in order to allow water to run off.\",\n \"Concrete surfaces are often poured to slope between ⅛ inch per foot to up to ⅝ inch per foot, with ¼ inch per foot being a common value.\",\n \"Therefore, the term “leveling” as it is used herein implies that the surface of the concrete is smoothed to conform to a flat surface between the top edges of the forms, and may include a built in amount of slope rather than being perfectly level relative to the earth's surface.\",\n \"That is, leveling wet concrete means to smooth the surface to be relatively flat across the tops of the two forms the concrete was poured into.\",\n \"In situations where multiple swaths are being poured to form a wide expanse of concrete, it is often the case that the previously poured swath of concrete, now hardened, is used in place of the forms on one side of the next swath to be poured.\",\n \"In such cases where a swath is being poured beside another, previously poured swatch, a spacer may be used to compensate for the level of freshly screeded concrete being slightly lower than the level of the underside of the screed, as discussed further in conjunction with FIG.\",\n \"5.Motorized screeds—that is, a screed mechanism attached to a skid loader or other motorized vehicle—are often used to save time and labor in pouring swaths of concrete.\",\n \"The present inventor recognized several drawbacks inherent in the designs of conventional mechanized screeds, for example, the Schoen screed of Published U.S. Patent Application 20090092444A1.One major drawback of it is that the front end loader of the conventional Schoen screed must be driven within the forms directly ahead of the wet concrete being leveled.\",\n \"Nearly all concrete is poured over one or more layers of iron rebar lying on a surface of sand which acts to strengthen and reinforce the concrete.\",\n \"Using the conventional Schoen motorized screed requires the skid loader to be driven over the rebar, pushing it into the layer of sand beneath the concrete and often causing deformities in the rebar.\",\n \"This would render the rebar useless unless remedied before the concrete dries.\",\n \"Thus, workers must be positioned between the conventional Schoen screed and the wet concrete being leveled to pull the rebar out of the sand.\",\n \"Another disadvantage of the Schoen device that the present inventor recognized involves the end form for the pour.\",\n \"An end form is the form at the end of the swath being poured, for example, to define the edge of a building pad or parking lot.\",\n \"A skid loader cannot be driven over the end form without destroying it.\",\n \"So, in order to use the Schoen device the end form must be assembled as soon as the front end loader of the conventional Schoen screed passes that point.\",\n \"Alternatively, some sort of makeshift removable bridge or ramps could be constructed over the end form, allowing the front end loader of the conventional Schoen screed to be driven up over the end forms without damaging them.\",\n \"These, and other drawbacks of the conventional screeds recognized by the present inventor, are overcome by various embodiments disclosed herein.\",\n \"FIG.\",\n \"1 is an oblique view of a wide swath offset concrete screed 100 according to various embodiments disclosed herein.\",\n \"The wide swath concrete screed is mounted on a motorized vehicle 101 such as a skid loader, an extension loader, a front end loader, a tractor, a backhoe, a truck, a tractor, a tracked loader, or other such motorized vehicle.\",\n \"The wheeled vehicle 101 has a liftable mechanical arm 119 of sufficient strength to hold the screed assembly with the capability of lifting it up and down.\",\n \"The offset wide swath concrete screed 100 affords the advantage of being mounted to the side of motorized vehicle 101—that is, the concrete screed 100 is mounted such that the screed bar 107 is offset to the side of the motorized vehicle 101.To be considered “offset” the screed bar 107 must be positioned outside the wheels (or track, if a tracked vehicle) in the direction of an axel of the motorized vehicle 101.This offset mounting configuration allows the motorized vehicle 101 to be driven along the outside of concrete forms 197.This is a significant advantage over conventional mechanized screeds that drive within the concrete forms.\",\n \"In this way the various embodiments disclosed herein do not push the rebar 199 into the sand as the concrete is being screeded.\",\n \"Moreover, the various embodiments of the wide swath concrete screed disclosed herein are able to screed concrete right to the end of the longitudinal forms without damaging the end form.\",\n \"Various embodiments of screeds disclosed herein are also capable of being mounted directly in front of the motorized vehicle 101 for those situations when there is insufficient room alongside the forms 197 to drive the motorized vehicle 101, e.g., when the last swath being poured is up against a fence, wall or building.\",\n \"The liftable arm 119 of the motorized vehicle 101 allows a user to lift the concrete screed 100 up and down as needed during the pour.\",\n \"Since the concrete screed 100 may weigh 300 pounds or more, with an outer end that extends beyond the motorized vehicle 101 by several feet more the width of the longitudinal forms, the liftable arm 119 must have sufficient strength to withstand the rotational force due to the weight of the concrete screed 100 hanging out to the side.\",\n \"The offset concrete screed 100 includes a connection mechanism 143 or structure for attaching the cross support bar 103 to the motorized vehicle 101.In some embodiments the connection mechanism 143 includes two metal plates bolted together to clamp down on the cross support bar 103 and hold it securely to the liftable arm 119.In some embodiments the connection mechanism 143 includes U-bolts, or metal cables, to secure the cross support bar 103 to the liftable arm 119.In other embodiments the connection mechanism 143 includes an adapter to fasten the cross support bar 103 to a fork lift attachment, or a three-point hitch, of the liftable arm 119.In yet other embodiments the connection mechanism 143 attaches to a hydraulic cylinder to affix the cross support bar 103 to the motorized vehicle 101.Regardless of the configuration, the various embodiments of the connection mechanism 143 includes structural means for attaching the cross support bar 103 to the liftable arm 119 of the motorized vehicle 101, either in a stationary position or in a manner capable of hinging.\",\n \"A screed bar 107 is configured to pull the mounds of wet concrete slurry deposited within the forms by a concrete truck.\",\n \"In this way the slurry is leveled during a pour by the action of the motorized vehicle driving back and forth on the outside of forms 197.The screed bar 107 is pulled by lateral support bars 105, which in turn, are connected to cross support bar 103.The motorized vehicle 101 may be positioned to push the cross support bar 103 in the direction of screeding movement 173, as shown in FIG.\",\n \"1.Alternatively, the motorized vehicle 101 may be positioned on the other side of the cross support bar 103 so as to pull the cross support bar 103 in the direction of movement 173.In either case, the screed bar 107 is dragged behind the cross support bar 103 as the wet concrete slurry is being screeded.\",\n \"This dragging motion prevents the screed bar 107 from jamming down or catching on the forms as it is moved along.\",\n \"The screed bar 107 is of sufficient length for both ends to rest on the longitudinal forms 197.Typically the screed bar 107 is slightly wider than the distance between the longitudinal forms 197 so that the screed bar 107 extends beyond the longitudinal forms 197 by a few inches.\",\n \"In a typical implementation the screed bar 107 may be from 6 to 24 inches longer than the distance between the longitudinal forms 197.In other implementations the screed bar 107 may be any length from the same width as the outer width of the forms up to ten or more feet wider than the width of the forms.\",\n \"There is no set limit as to how much wider the screed bar 107 is as compared to the width of the forms 197.However, since workers often walk or stand just outside the forms it tends to be more safe and convenient for the width of the screed bar 107 to extend beyond the forms by no more than a few inches on each side.\",\n \"For example, in some embodiments the screed bar 107 is of a sufficient length so that it extends beyond the forms by 8-10 inches on either side to keep the screed from falling inside the forms 197.Depending upon the application, the swatch of concrete may be of any given width.\",\n \"For some uses the width of the concrete swath is not important.\",\n \"For example, a large expanse of concrete such as a parking lot may sometimes be poured in strips or swaths of any width, up to the maximum width, that is desired by the prime contractor or suitable for the situation.\",\n \"However, some applications (and some builders) require that the concrete be poured in a specific width swatch, e.g., 12 feet, 15 feet, 20 feet, 25 feet, 30 feet, or other such swath widths.\",\n \"To accommodate these specific swath widths, the concrete screed 100 may be equipped with various lengths of screed bar 107.In some embodiments, the length of the screed bar 107 is fixed, and bars of various lengths are swapped out to accommodate the required swath width.\",\n \"Other embodiments of the screed bar 107 are configured so that the length of the screed bar 107 may be adjusted to suit the distance between the forms 197 or other parameters.\",\n \"This may be achieved by providing a telescoping screed bar 107, or by providing removable sections of the screed bar 107 which may be swapped out to achieve the desired length.\",\n \"The screed bar 107 is held by two or more lateral support bars 105, which in turn, are connected to a cross support bar 103.To smooth out the mounds of wet concrete the motorized vehicle 101 is typically positioned to push the cross support bar 103.However, the cross support bar 103 is configured to pull the screed bar 107 along, dragging the wet concrete to a level format.\",\n \"This pulling action aids in preventing the screed bar 107 from gouging into the longitudinal forms, thus making the screed bar 107 operate more smoothly as the wet concrete is being leveled.\",\n \"FIG.\",\n \"2 is an oblique view depicting wide swath offset concrete screed 100 in use as wet concrete is being poured.\",\n \"The figure shows the point in time when the wet concrete from one truck has already been leveled out, the screed bar 107 has been lifted up out of the way, and motorized vehicle of 101 (not shown) of the concrete screed 100 is backed up so as to allow another truckload of wet concrete to be poured.\",\n \"As shown in FIG.\",\n \"2 the lateral support bar 105 is attached to the cross support bar 103 by a hinge assembly 109 configured to hinge upward as the screed bar 107 comes to rest on forms 197.The hinge assembly 109 prevents the screed bar 107 from hinging downward more than a predetermined amount, in order to lift the screed bar 107 off the forms as shown in FIG.\",\n \"2.The predetermined amount—defined as the support bar angle—is measured at the point where the motorized vehicle 101's liftable arm 119 has been lowered such that the screed bar 107 just touches the forms 197.That is, the support bar angle is the angle between the axis of rotation of the hinge assembly 109 and the bottom front edge of the screed bar 107 when it is lowered to the point of just touching the forms 197.It should be clear from this that the the support bar angle does not depend upon the shape of the lateral support bar 105.At this point, if the cross support bar 103 is raised it will lift the screed bar 107 up since the hinge assembly 109 won't hinge downward past the support bar angle.\",\n \"On the other hand, if the cross support bar 103 is instead lowered the hinge assembly 109 will hinge upward since the screed bar 107 is resting on the forms 197.Various embodiments are configured so the lateral support bar 105 hangs downward at a support bar angle of from 1 degree to as much as 60 degrees, or any angle within these limits, with a hang angle of 15 degrees being typical.\",\n \"The lower limit of the support bar angle, 1 degrees, is determined by the distance between the axis of rotation of the hinge assembly 109 and the bottom surface of the cross support bar 103, and depends on the length of the lateral support bar 105.FIG.\",\n \"3 is a close up view depicting details of one embodiment of the hinge assembly 109 between the lateral support bar 105 and the cross support bar 103.Other embodiments may use like types of structures configured to provide a hinging action such as an ordinary hinge, a rocker arm assembly, a trough holding the ends of lateral support bars 105 and flexible cable controlling the maximum hinge angle or support bar angle, a ball joint, or other like types of hinging structures.\",\n \"The hinge assembly 109 connects the lateral support bar 105 to the cross support bar 103.The hinge assembly 109 allows the lateral support bar 105, and in turn the screed bar 107, to hinge upward as the device is lowered onto the longitudinal forms 199.As discussed above, the hinge assemblies 109 prevent the lateral support bars 105, and in turn the cross support bar 103, from hinging downward by more than a predetermined amount, defined as the support bar angle.\",\n \"In this way the motorized vehicle 101 can lift the screed bar 107 up in the air.\",\n \"The conventional Schoen screed of Published U.S. Patent Application 20090092444A1 features a mounting pocket 62 that prevents arm 48 from rotating too far downward.\",\n \"Such a pocket/arm assembly could be used with embodiments disclosed herein as a hinging mechanism.\",\n \"However, the present inventor recognized certain drawbacks with the Schoen pocket/arm assembly.\",\n \"Namely, the pocket tends to retain wet concrete and small pebbles during the course of a working day.\",\n \"This, in turn, makes the pocket difficult to clean upon completion of a work day.\",\n \"At the end of each day, and perhaps even during the course of the day, the bar 48 must be rotated upward out of pocket 62 in order to clean out all the accumulated concrete and pebbles.\",\n \"If the pocket 62 of the Schoen device is allowed to dry overnight without being thoroughly cleaned it will sometimes freeze in place as the bits of remaining concrete dry and harden.\",\n \"The Schoen device can also freeze up while it is being used if a small pebble or bit of concrete becomes lodged between the bar 48 and pocket 62.The hinge assembly 109 overcomes these drawbacks since it is a more open design which does not tend to accumulate pebbles and wet concrete.\",\n \"The hinge assembly 109 is easier to clean with a hose and water since there is no pocket for pebbles and wet concrete to gather in during the course of a day.\",\n \"In various embodiments of the offset concrete screed 100, the hinge assembly 109 is rotatably connected to cross support bar 103 by a pin 121.By “rotatably connected” it is meant that the hinge assembly is connected in a manner that allows it to rotate, or hinge, about an axis.\",\n \"In some implementations the pin 121 passes through, or is otherwise connected to, a pin holder bar 123.In other embodiments the pin 121 is connected directly to the cross support bar 103.The pin 121 may be a bolt of sufficient diameter (e.g., ⅜ to 1 inch) for supporting the weight of the lateral support bars 105 and screed bar 107.The bolt may be kept in place with a nut, or two nuts tightened against each other, and washers to aid in preventing wear on the bolt and hinge assembly 109.In other implementations a hinge pin, a metal rod, or other like type of pin may be used as the pin 121.In some embodiments one or more springs 167 are connected to some point on the support bar assembly to provide more downward force than the weight of the screed bar 107.The additional downward force aids in preventing the screed bar from riding up over the wet concrete slurry.\",\n \"Typically, the springs 167 are configured to be removable so that weaker or stronger springs—or multiple springs—can be attached, as needed.\",\n \"In this way the user is able to adjust the downward force to accommodate the conditions of the pour.\",\n \"Some embodiments use compression springs to push downward on the support bar assembly.\",\n \"In other embodiments leaf springs are used to provide the downward force.\",\n \"The hinge assembly 109 is typically configured so that it comes to rest against cross support bar 103 when the offset concrete screed 100 is raised up in the air.\",\n \"The hinge assembly 109 hinges upward in response to the concrete screed 100 being lowered so that the screed bar 107 rests on forms 197.This allows the screed bar 107 to ride along the top of the forms 197 without damaging the forms.\",\n \"The hinging action also allows the screed bar 107 to ride up over an overly large mound of wet concrete to avoid putting too much horizontal strain on the screed bar 107 and concrete screed 100.If the screed bar 107 rides up over an overly large mound of wet concrete the user can simply raise the offset concrete screed 100 up in the air, back up the motorized vehicle 101, and take one or more additional passes at smoothing the large mound of wet concrete.\",\n \"Since embodiments of the offset concrete screed 100 allow the motorized vehicle 101 to be driven off to the side rather than over the rebar, the user can efficiently make several passes without need to have workers reposition to rebar after each pass, as is required for conventional motorized screed devices.\",\n \"FIG.\",\n \"4 depicts the wide swath concrete screed 100 being used to level the wet concrete slurry 193 using a previously poured swath of concrete 195 in lieu of a form on one side.\",\n \"In pouring large expanses of concrete for a parking lot or building pad it is often the case that the swaths are poured side by side with the previous day's swath acting as a form on one side of the current pour.\",\n \"The very first swath poured requires a form 197 to be set up on each side of the swath to be poured.\",\n \"For each subsequent swath poured after the previous swath has hardened (e.g., a day or more later) only one form 197 needs to be erected.\",\n \"The previously poured swath 195, now hardened, acts as a form on the other side to contain the newly poured wet concrete slurry 193.One issue with using a previously poured swath in lieu of a form is that the process or screeding wet concrete results in a screeding process delta in which the level of the concrete is slightly lower than the level of the forms (or the form and the previously poured swath being used as a form).\",\n \"For example, a screeded concrete surface may end up ¼ inch or so lower than the forms on either side—that is, have a screeding process delta of ¼ inch or so.\",\n \"This is because the wet concrete slurry contains small pebbles and gravel in it.\",\n \"The screeding process delta results because the screed bar 107 tends to push some of the small pebbles and gravel in front of it, causing the screeded surface of the wet concrete slurry to be slightly lower than the bottom surface of screed bar 107, e.g., ¼ inch or so lower.\",\n \"This can be somewhat troublesome if the concrete is being poured in long swaths alongside a previously poured swath—now hardened—from the previous day.\",\n \"If the screeding process delta was not compensated for and the form 197 was erected to be level with the previously poured swath, each newly poured swath would end up being ¼ inch or so lower than the previously poured swath beside it.\",\n \"If a number of swaths were poured this way the result would be that each swath would be ¼ inch or so lower due to the screeding process delta of each swath.\",\n \"In order to avoid this, it is desirable to provide forms 197 for the new swath to be poured that are at a level slightly higher than the previously poured swath to its side by an amount equal to the anticipated screeding process delta.\",\n \"The slightly higher level of the form 197 compensates for the lower level of finished concrete due to the screed bar 107 pushing small pebbles and gravel in front of it.\",\n \"However, if the previously poured swath (which has hardened) is being used as one of the forms 197 then it is not possible to adjust the height of the previously poured swath to compensate for the screeding process delta.\",\n \"To this end, various embodiments use a screed bar spacer affixed to the bottom of screed bar 107 on the side of the previously poured swath in conjunction with the form 197 being constructed slightly higher than the level of the previously poured swath.\",\n \"FIG.\",\n \"4 also depicts a screed bar extension 135.The cross section of the screed bar extension 135 is typically the same as the screed bar 107, with a slightly smaller cross-sectional portion that fits into the end of the screed bar 107.One or more holes 139 may be provided for bolts 141 used to secure the screed bar extension 135 to the screed bar 107.The bolts 141 pass through holes 139 and tighten into threaded holes 137.FIG.\",\n \"4 also depicts the wide swath concrete screed equipped with a scrape auger 181.The scrape auger 181 acts to push excess wet slurry concrete to one side or the other so as to aid in preventing too much wet slurry concrete from building up and pouring over the top of screed bar 107.Typically, the lower edge of the scrape auger 181 is positioned slightly above the lower edge of screed bar 107, e.g., one to three inches, but may be positioned as little as ¼ inch to as much as one foot above the lower edge of screed bar 107.The scrape auger 181 may either be affixed to the cross support bar 103 or may be affixed to lateral support bars 105 by connection points 179.Typically, connection points 179 have a bearing or greased sleeve to reduce the mechanical friction as the auger 181 rotates.\",\n \"The auger 181 is rotationally powered by a power unit 183.The power unit 183 may be similar to power unit 185 depicted in FIG.\",\n \"11B.\",\n \"Power unit 183 may be implemented in various forms, including for example, a gas or diesel engine, an electric motor, a hydraulic motor, a rotating shaft connected to the power take-off of the motorized vehicle, a rotating linkage connected to the engine of the motorized vehicle, or other like type of power unit known to those of ordinary skill in the art.\",\n \"The power unit 183 may either be connected to the cross support bar 103, or in other implementations, may be connected to one or more of the lateral support bars 105.The power unit 183 may be controlled by a user to controllably rotate the auger 181 at varying speeds.\",\n \"The auger 181 may be rotated in one direction to push the wet concrete slurry towards the motorized vehicle 101, and may be controlled to rotate in the opposite direction to push the wet concrete slurry away from the motorized vehicle 101.FIG.\",\n \"5 depicts embodiments 500 and 550 of an optional screed bar spacer and subgrade screeder 147 attachments that may be affixed to the screed bar.\",\n \"As shown in the figure, the screed bar spacer 125 is affixed to the end of the screed bar 107 resting on a previously poured concrete surface 195 to compensate for the screeding process delta.\",\n \"The screed bar spacer 125 is a removable attachment with a predetermined thickness that compensates for the level of freshly screeded concrete being slightly lower than the level of the underside of the screed bar 107 due to small pebbles and gravel being pushed in front of screed bar 107 during the screeding process.\",\n \"A user simply taps the screed bar spacer 125 into position within the screed bar 107, and it is held in place by friction.\",\n \"To remove the screed bar spacer 125, the user merely taps it back out.\",\n \"The screed bar spacer 125 is held to the bottom side of screed bar 107 on the end that rides across the swath of previously poured, hardened concrete.\",\n \"Since the level of the freshly screeded concrete will be lower by a slight amount than the bottom of the screed bar 107 due to the screeding process delta, the screed bar spacer 125 allows the screed bar 107 to pass over the newly poured concrete at a level slightly higher than the desired level of the finished concrete surface to compensate for the screeding process delta.\",\n \"In this way, the newly screeded concrete will end up at approximately the same level as the previously poured concrete swath adjacent to it.\",\n \"The wide swath offset concrete screed 100 may be provisioned with screed bar spacers 125 of various thicknesses, depending upon the anticipated amount of screeding process delta—that is, the amount that the newly poured concrete is anticipated to be lower.\",\n \"The anticipated amount of screeding process delta depends upon the characteristics of the wet concrete slurry such as the size of the pebbles and gravel in the wet concrete slurry, how wet the concrete slurry is, the temperature of the wet concrete slurry, etc.\",\n \"Since a given contractor may order wet concrete slurry many times from the same concrete supplier, the contractor will generally get a feel for the amount of screeding process delta to expect from a particular concrete provider for a given grade of concrete.\",\n \"A screed bar spacer 125 for use with the various embodiments may have a predetermined thickness of as little as 1/16 inch or as much as ¾ inch, or any value in between, depending upon the characteristics of the wet concrete slurry resulting in screeding process delta.\",\n \"A typical thickness for a slab of concrete 8 inches thick is ¼ inch.\",\n \"In various embodiments the bottom side of the screed bar spacer 125 is smooth with rounded corners in order to push the pebbles and gravel of the wet concrete slurry underneath it during the screeding process.\",\n \"This aids in preventing the pebbles and gravel from scraping along the surface of the wet concrete slurry before they pass beneath the screed bar spacer 125.In addition the screed bar spacer 125 is configured to be smooth with rounded corners aids to avoid gouging or scoring the concrete surface that it rests and slides upon.\",\n \"FIG.\",\n \"5 depicts another screed bar spacer embodiment—the screed bar spacer 127 which is configured with a wheel that rolls along the previously poured concrete surface 195.The screed bar spacer 127 is particularly useful when the previously poured concrete 195 has not yet hardened sufficiently to avoid scoring the surface.\",\n \"The screed bar spacer 127 slides into screed bar 107, and is tightened into place with a compression bolt 133.Moreover, the screed bar spacer 127 may be configured to be adjustable by providing an elongated slot either for bolt 129 or for a bolt at point 131.FIG.\",\n \"5 also depicts a subgrade screeder attachment 147.To preparing a pour site the contractor generally deposits gravel, sand or pebbles, or some other subgrade material, between the longitudinal forms 197.It is important to have a uniformly flat, level subgrade surface to pour the wet concrete slurry on, in order to ensure that the resulting concrete pad is of a uniform thickness.\",\n \"According to conventional methods, the subgrade material is graded and leveled by hand with shovels or rakes.\",\n \"These conventional methods of preparing the subgrade are quite a labor intensive and must be performed prior to pouring the concrete.\",\n \"It generally takes at least a couple—or even several—manual laborers working to smooth and level the subgrade material by hand, and it is nearly impossible to create a uniformly flat, level subgrade surface.\",\n \"The embodiments disclosed herein overcome aid in cutting down the manual labor required to prepare the subgrade materials by hand, while at the same time drastically increasing the precision of the subgrade leveling process.\",\n \"The subgrade screeder attachment 147 depicted in FIG.\",\n \"5 attaches to the screed bar 107 using one or more bolts 149.Alternatively, the subgrade screeder attachment 147 may be affixed to the screed bar 107 using pins, clamps, cables, chains, or other like type of structures for affixing the subgrade screeder attachment 147 in place on the screed bar 107.In other embodiments the subgrade screeder attachment 147 is attached to the screed bar 107 with a hinge mechanism so that it can be hinged upward out of the way when not in use.\",\n \"The depth that the subgrade screeder attachment 147 extends below the lower level of screed bar 107 is adjustable in order to equal the desired thickness of the concrete pad being poured.\",\n \"In the embodiment depicted in FIG.\",\n \"5 there are a series of holes that allow the subgrade screeder attachment 147 to be set at various depths, thus creating concrete pads of various thicknesses.\",\n \"In other embodiments the subgrade screeder attachment 147 has an elongated hole, or slot, to allow adjustment up and down to create various thickness of a concrete pad.\",\n \"Typically, the width of the subgrade screeder attachment 147 is slightly narrower than the width of the longitudinal forms 197, for example, one to six inches narrower.\",\n \"The screeder attachment 147 may be provided in multiple pieces so as to easily vary the width to accommodate the width of the longitudinal forms 197.The subgrade screeder attachment 147 is typically made of metal.\",\n \"Aluminum generally provides sufficient strength, and is advantageously lightweight.\",\n \"However, other implementations of the subgrade screeder attachment 147 may be made of iron, steel, or other like metals.\",\n \"In some embodiments the lower edge of the subgrade screeder attachment 147 may be curved slightly in the direction of screeding movement 173.The slight curve tends to cut into the loose gravel, sand or pebbles typically used as subgrade material, thus pulling the subgrade screeder attachment 147 slightly downward to create a smooth, level subgrade surface.\",\n \"In various embodiments the curved portion of the lower edge of the subgrade screeder attachment 147 is angled from as little as 15 degrees to as much as 90 degrees, relative to vertical.\",\n \"In other embodiments the lower edge of the subgrade screeder attachment 147 is squared off straight, rather than having a slight curve as shown in FIG.\",\n \"5.FIG.\",\n \"6 depicts the wide swath offset concrete screed 100 in a raised position.\",\n \"In some instances the area just outside the forms and just beyond the end of the swath of concrete being poured may have an obstacle such as a fence or building, or otherwise be inaccessible.\",\n \"When this occurs it may not be possible to drive the motorized vehicle 101 very far beyond the end of the swath of concrete.\",\n \"In such situations it is useful to be able to lift the concrete screed 100 high enough to permit a concrete truck to back up close enough to unload the wet concrete beneath the raised screed.\",\n \"Various embodiments of the concrete screed 100 can be raise high enough to permit wet concrete to be unloaded beneath it, as shown in FIG.\",\n \"6.For example, depending upon the type of motorized vehicle 101 being used, the wide swath offset concrete screed 100 can be raised to a level of fifteen feet or more.\",\n \"For embodiments using an extension loader as the motorized vehicle 101 as depicted in FIG.\",\n \"6 the offset concrete screed 100 can be raised to over twelve feet.\",\n \"This is sufficient height to allow a concrete truck to back up and deliver its load of wet concrete slurry under the offset concrete screed 100.Other embodiments may raise the concrete screed 100 even higher, for example, for clearance beneath the screed bar 107 of 15 feet or even more, depending upon how far the liftable arm 119 of the motorized vehicle 101 is able to extend or rise in the air.\",\n \"As the liftable arm 119 is lowered it is desirable not to slam it into the lateral forms 197.To aid in this some embodiments include a flow restrictor 145 in the hydraulic line to controllably constrict the flow of hydraulic fluid.\",\n \"The flow restrictor 145 tends to slow down the upward and downward movement of the liftable arm 119, making it easier for a user to ease the liftable arm 119 into position as it is raised and lowered during the screeding process.\",\n \"FIG.\",\n \"7 depicts a lateral support bar 105 configured to have a slight amount of curve at point 175.In various embodiments it is desirable for the underside of screed bar 105 to lay relatively flat on the wet concrete slurry and the longitudinal forms 197.Having the underside of screed bar 105 flat aids in keeping it from riding up over mounds of wet concrete slurry as it is pulled along, or gouging into the wet concrete.\",\n \"Further, the flat underside as it is drawn over the wet concrete slurry provides a smoothing effect that helps to produce a smooth, level surface of the finished concrete.\",\n \"At the same time it is desirable to keep the cross support bar 103 several inches above the forms 197 to keep it from catching on the forms 197 and causing perturbations in the smooth surface of the concrete.\",\n \"To achieve this—having the underside of screed bar 105 flat while the cross support bar

four feet long.\",\n \"However, the length may be varied depending upon the requirements of the pour and the situation in which it is to be used to be as short as one foot or as long as twelve feet.\",\n \"Using shorter lateral support bars 105 will result in the cross support bar 103 being positioned closer to the forms 197.Using longer lateral support bars 105 will result in more downward rotational force on the cross support bar 103 due to the increased leverage.\",\n \"Therefore, in various embodiments the lateral support bars 105 are generally kept within three to six feet, with four feet being a typical length embodiment.\",\n \"FIG.\",\n \"8 is a flowchart depicting the use of the concrete screed 100 according to various embodiments of the invention.\",\n \"Reference is

be poured into forms on either side (e.g., for the first concrete swath to be poured), or a previously poured, now hardened, swath of concrete is to be used on one side of the pour in place of the longitudinal forms for that side.\",\n \"If previously poured swath of concrete is to be used in place of the forms it may be the case that the screeding will result in a screeding process delta in which the level of the concrete is slightly lower than the level of the forms, as discussed previously in conjunction with FIG.\",\n \"5.If a screeding process delta—that is, a level of the concrete surface slightly lower than the scree bar surface—is anticipated, the method proceeds from block 813 along the “YES” path to block 815 to attach a screed bar spacer 125 or 127.However, if no screed bar spacer is desired the method proceeds from block 813 along the “NO” path to block 817.In block 817 the user operates the motorized vehicle 101 to screed the wet concrete slurry to a desired degree of levelness.\",\n \"During the screeding process it is sometimes the case that the screed bar 107 needs to be raised, for example, to back the motorized vehicle 101 up or to allow a concrete truck to deliver another load of concrete.\",\n \"If, in block 819, it is determined that the screed bar 107 needs to be raised the method proceeds along the “YES” path to block 823 to raise the screed bar 107 (or lower it if it was previously raised).\",\n \"The method then proceeds to block 821 to determine whether further screeding operations need to be performed.\",\n \"If further screeding is to be done, the method proceeds back to block 817 along the “YES” path.\",\n \"However, if the screeding is completed the method proceeds from block 821 along the “NO” path to block 825 where the method ends.\",\n \"Various activities of the method disclosed herein may be included or excluded as described above, or maybe performed in a different order than the particular examples chosen to illustrate the embodiments.\",\n \"For example, it may be the case that the screed bar extension may be attached to the screed bar (block 811) prior to attaching the screed bar to the lateral support bar (block 807).\",\n \"Or it may be the case that the screed bar spacer may be attached to the screed bar (block 815) prior to attaching the screed bar to the lateral support bar (block 807).\",\n \"The sequence of steps for performing the method of making and using a wide swath offset concrete screed according to the various embodiments disclosed herein may be altered in many other ways as well.\",\n \"FIGS.\",\n \"9-10 are oblique views depicting embodiments of an up-down offset concrete screed.\",\n \"The present inventor recognized the difficulty of screeding concrete into certain tight spaces—for example, screeding into the corner formed by two buildings, or screeding right up against a building or a wall.\",\n \"In such tight spaces it is desirable to be able to operate the screed as closely as possible up to the limiting obstruction.\",\n \"The embodiments depicted in FIGS.\",\n \"9-10 make it possible to screed into tight places with only a minimum of finish work to be done by hand.\",\n \"The up-down offset concrete screed embodiment features two or more vertical support bars 151.The vertical support bars 151 are designed to move up and down, as needed, during the screeding operation.\",\n \"For example, it may be that the surface outside the forms on which the motorized vehicle 101 is driving is unlevel or bumpy.\",\n \"If the motorized vehicle 101 moves up or down as it is traveling along, the vertical support bars 151 can move down or up, as needed, so that the screed bar 107 may remain on the forms 197.In some instances, if there is too much wet concrete slurry 193 being pushed the screed bar 107 may ride up over the slurry, leaving an unlevel spot that will require further screeding on another pass.\",\n \"Each vertical support bar 151 is enclosed by a support bar sleeve 153 that allows the vertical support bar 151 to move up and down.\",\n \"The end of each vertical support bar 151 is larger than the passage dimensions of the support bar sleeve 153 to prevent the vertical support bar 151 from passing through it.\",\n \"This allows the cross support bar 103 to lift up the vertical support bar 151 and accompanying screed bar 107.To aid in the up/down movement the support bar sleeves 153 have bearings on their inner surface, making it easier for the vertical support bars 151 to ride up and down with the lateral force of the concrete slurry pushing against them.\",\n \"Alternatively, the support bar sleeves 153 may have small wheels or lubricant instead of bearings.\",\n \"The vertical support bars 151 are rotatably attached to the screed bar 107 allowing the vertical support bars 151 to rotate about an axis, the axis being in the direction of screeding—that is, the axis of rotation is in the same direction as the direction of screeding (e.g., motorized vehicle movement), allowing the direction of rotation to be back and forth at a right angle to the direction of screeding.\",\n \"Similarly, the support bar sleeves 153 are rotatably attached to the cross support bar 103.In this way, if the motorized vehicle 101 drives on an unlevel or bumpy spot causing the cross support bar 103 to raise up or dip relative to the screed bar 107, the vertical support bars 151 won't bind up if they raise or drop by different amounts.\",\n \"In this way the screeding operation can continue smoothly even though the cross support bar 103 does not remain parallel with the screed bar 107.The vertical support bars 151 may be rotatably attached to the screed bar 107 by a tab 155 that is welded, bolted or otherwise affixed to the screed bar 107.The tab 155 has a pin or bolt configured to pass through a hole in the vertical support bar 151, thus allowing the vertical support bars 151 to rotate relative to the screed bar 107.In other embodiments (no shown) the tab 151 is affixed to the vertical support bar 151 and has a bolt or pin that passes through a hole in the screed bar 107.FIG.\",\n \"10 depicts details of an embodiment for rotatably connecting the support bar sleeves 153 to the cross support bar 103.FIG.\",\n \"10 is oblique cutaway view of an embodiment of the support bar sleeve 153 that rotatably attaches the support bar sleeve 153 to the cross support bar 103.In this embodiment the hinging mechanism is a bolt 157 that is welded, or otherwise attached, to the support bar sleeve 153 and passes through a hole 159 in the cross support bar 103.The bolt 157 allows the support bar sleeve 153 to rotate as needed relative to the the cross support bar 103.Other hinge mechanisms may be used in various implementations to connect the vertical support bars 151 to either the support bar 103 or to the screed bar 107, including for example, a hinge, a flexible cable, chain links affixed to each part, a shaft and bearings, a trough or slot that supports a shaft, or other like mechanisms known to those of ordinary skill in the art.\",\n \"FIG.\",\n \"11A depicts an embodiment of a vibrating float assembly configured to be pulled behind the screed bar 107.In typical implementations the vibrating float assembly is fairly lightweight, for example, weighing between five and twenty-five pounds.\",\n \"However, either heavier or lighter implementations may be constructed, depending upon the dimensions and materials used in the vibrating float assembly itself, and the characteristics of the concrete slurry being floated.\",\n \"Typically, two or more vibrating float assemblies are rotatably affixed to the screed bar 107.In some embodiments two or more points on the screed bar 107 serve as the points of rotation for the float assemblies to hinge, or rotate, downward onto the surface of the wet concrete slurry.\",\n \"In other embodiments, as shown in FIG.\",\n \"11B, the float assembly itself—in the form of a roller screed—rotates about an axis connected to screed bar 107.Turning again to FIG.\",\n \"11A, some embodiments feature only one float affixed to the screed bar 107.The screed bar 107 generally is configured to extend beyond the outermost and innermost vibrating float assemblies by at least a few inches.\",\n \"That way, the vibrating float assemblies ride solely on the wet concrete slurry and do not extend quite to the forms.\",\n \"However, in some implementations, the vibrating float assemblies may be configured to be the same width as the screed bar 107 so the outermost portions of the vibrating float assemblies ride on the forms just as the screed bar 107 does.\",\n \"Each vibrating float assembly has a float pan 161.The float pans 161 are constructed in various lengths, depending upon the length of the screed bar 107 to which they are attached.\",\n \"The float pans 161 attached to a particular screed bar 107 do not all necessarily need to be the same length.\",\n \"For example, a 17foot screed bar 107 for use on forms 197 that are 16 feet apart may have an 8 foot float pan 161 and a seven foot float pan 161 which are spaced 2 inches apart.\",\n \"This would leave 5 inches of space between the outmost edges of the float pans 161 and the forms 197.The float pan 161 features a lip that is bent upwards the full length of the pan.\",\n \"The bent lip may be from one to four inches wide.\",\n \"In typical implementations the bent lip is approximately two inches wide and the overall width of the pan is approximately twelve inches.\",\n \"The bent lip may be bent upwards from as little as 3 degrees to as much as 60 degrees.\",\n \"In typical implementations, the bent lip may be bent upwards from 35 to 55 degrees, with 45 degrees being a common amount.\",\n \"The flat bottom surface of the float pan 161 is generally configured to be wider than the bent lip portion, e.g., from 2 inches to 20 inches wide.\",\n \"In typical implementations, the flat bottom portion is from six to twelve inches wide.\",\n \"The float pan 161 may be constructed from a number of materials, including for example, aluminum, magnesium, steel, iron, wood, composite material, or the like.\",\n \"Each float pan 161 has mounted upon it a vibrating mechanism—typically an off-balance vibrating electric motor.\",\n \"The electric motor may either be wired to a power source back on the motorized vehicle such as the vehicle's battery, or may have a battery pack mounted in place with it on the float pan 161.The motor and battery pack are generally mounted towards the center of the float pan 161 to evenly distribute their weight across the wet concrete slurry.\",\n \"Each float pan 161 is affixed to the screed bar 107 by one or more float hinge mechanisms.\",\n \"The embodiment depicted in FIG.\",\n \"11A has a float hinge mechanism features a U-shaped member that fits snuggly over the screed bar 107.In some embodiments the U-shaped member may bolt, screw or otherwise be attached to the screed bar 107 so as to be more firmly attached than friction would allow.\",\n \"The hinge member 163 is rotatably connected to a hinge tab 165.The hinge tab 165 is affixed to the float bar 107 by welding, bolts, rivets, screws, or other ways of attaching materials together known to those of skill in the art.\",\n \"The hinge member 163 is rotatably connected to a hinge tab 165 by a bolt or pin, allowing it to rotate in the direction 169.Typically, the float hinge mechanism is configured to allow the float pan to hinge downward from horizontal by a limited amount somewhat less than 30 degrees.\",\n \"For example, in one embodiment the float pan can hinge downward an amount between 1 and 15 degrees—with an amount of downward hinging between 1 and 6 degrees being typical.\",\n \"To measure it another way, the hinge mechanism allows the float pan to hinge downward from 1 to 4 inches, as measured by the distance the float bar 107 is raised above the level of the forms 197 before the float pan's rear edge begins to come off the surface of the wet concrete slurry.\",\n \"In this way, the float pan will gently ride on top of the concrete slurry to a horizontal position as the screed bar 107 is lowered towards the forms 197.If the float pan is allowed to hinge down into too steep of an angle, it will gouge into the wet concrete slurry as the screed bar 107 is lowered.\",\n \"FIG.\",\n \"11B depicts an embodiment in which the float bar is in the form of a rotating float assembly, typically called a roller screed.\",\n \"The roller screed 187 is manipulated back and forth to smooth the surface of the wet concrete slurry.\",\n \"In various embodiments the direction of rotation at the point where the roller screed 187 meets the wet concrete slurry is in direction 171 towards the slurry yet to be smoothed, that is, towards the wet concrete slurry that has just been delivered by a concrete truck.\",\n \"In some embodiments (e.g., the embodiment of FIG.\",\n \"11B) the roller screed 187 may take the place of the screed bar 107 itself, shown in FIGS.\",\n \"1-6.In other embodiments one or more roller screed(s) 187 may be configured in the manner of the float pans attached behind the screed bar 107 as shown in FIG.\",\n \"11A.\",\n \"In various roller screed embodiments the roller screed 187 is rotated by one or more power units 185.The power unit 185 may be implemented in various forms, including for example, a gas or diesel engine, an electric motor, a hydraulic motor, a rotating shaft connected to the power take-off of the motorized vehicle, a rotating linkage connected to the engine of the motorized vehicle, or other like type of power unit known to those of ordinary skill in the art.\",\n \"In various embodiments the power unit 185 may be connected to the cross support bar 103.In various embodiments the power unit 185 may be connected to one or more of the lateral support bars 105.The power unit 185 may be controlled by a user to controllably rotate the roller screed 187.This allows the rotation speed of the roller screed 187 to be adjusted, and turned on and off, so as to accommodate different pouring conditions.\",\n \"In some embodiments equipped with both a roller screed 187 and an auger 181 the same power unit may be used to rotate both the roller screed 187 and the auger 181.In some roller screed embodiments the lateral support bars 105 may be configured to hinge upward as shown in FIG.\",\n \"11B.\",\n \"In other embodiments the lateral support bars 105 may be rigidly affixed to the cross support bar 103 without a provision to hinge upward.\",\n \"In yet other embodiments one or more springs may be provided to provide

various embodiments the roller screed 187 is rotatably connected at both ends to a roller support structure 189.The roller support structure 189 may be configured on the outside and above the roller screed 187 as shown in FIG.\",\n \"11B, or may be configured to pass through the center of roller screed 187.The support structure 189 is at least above the lower edge of roller screed 187 so as to

reference numerals and/or letters in the various examples.","This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.","Further, spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures.","The spatially relative terms are intended to encompass different orientations of the device in

with dense and nanoscale patterns.","When fabricating dense patterns, a directed self-assembly (DSA) process may be used to enhance and augment the existing semiconductor manufacturing capabilities.","In a typical DSA process, a block copolymer (BCP) film is formed over lithographically defined surfaces and a microphase separation is induced to cause the constituent polymer

does not in itself dictate a relationship between the various embodiments and/or configurations discussed.\",\n \"Further, spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures.\",\n \"The spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.\",\n \"The apparatus may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein may likewise be interpreted accordingly.\",\n \"The present disclosure is generally related to semiconductor devices, and more particularly to methods for manufacturing semiconductor devices with dense and nanoscale patterns.\",\n \"When fabricating dense patterns, a directed self-assembly (DSA) process may be used to enhance and augment the existing semiconductor manufacturing capabilities.\",\n \"In a typical DSA process, a block copolymer (BCP) film is formed over lithographically defined surfaces and a microphase separation is induced to cause the constituent polymer molecules to self-assemble, thus creating densely packed features with uniform dimensions and shapes.\",\n \"A BCP film or simply a BCP includes polymers comprised of at least two different polymer segments.\",\n \"These polymer segments are configured to assemble themselves into highly ordered structures under certain conditions such as for example, when they are exposed to an elevated temperature.\",\n \"In general, a neutral layer or an orientation layer is disposed on a surface of a substrate of a lithographically defined surface before forming the BCP film.\",\n \"The neutral layer has no affinity for either of the polymer segments of the BCP film.\",\n \"During a DSA process, the neutral layer may be able to lead/orientate a first polymer segment for directed self-assembly.\",\n \"However, in order to orientate a second polymer segment for directed self-assembly, at least one additional process (e.g., forming another neutral layer using the additional process to orientate the second polymer segment) is required.\",\n \"The forming the another neutral layer generally includes multiple process to be involved such as for example, removing part of the neutral layer that leads the first polymer segment, providing a pattern for the neutral layer that is to lead the second polymer segment, and removing the patterned neutral layer.\",\n \"In contrast, the present disclosure provides various embodiments of a method to form an improved neutral layer without requiring the above-identified additional processes.\",\n \"Referring now to FIG.\",\n \"1, a flow chart of a method 100 of forming a semiconductor device is illustrated according to various aspects

schematic view of a high-frequency treatment system 10 according to the present embodiment.","As illustrated in this Figure, the high-frequency treatment system 10 includes a high-frequency treatment instrument 100 which functions as a high-frequency treatment instrument, an electric power source device 200 which supplies electric power to the treatment instrument, and a footswitch 290.The high-frequency treatment instrument 100 includes a treatment portion 110, a shaft 160, and an operation portion 170.For the purpose of descriptions below, the treatment portion 110 side is referred to as a distal side, and the operation portion 170 side is referred to as a proximal side.","The high-frequency treatment system 10 is configured to grasp a biological tissue, such as a blood vessel, which is a treatment target, by the treatment portion 110.The high-frequency treatment system 10 applies a high-frequency voltage to the grasped biological tissue, thereby sealing this biological tissue.","The treatment portion 110, which is provided at a distal end of the shaft 160, is provided with a first grasping member 112 and a second grasping member 114, which are a pair of grasping members.","Those parts of the first grasping member 112 and second grasping member 114, which come in contact with the biological tissue, function as electrodes, respectively.","Specifically, the first grasping member 112 and second grasping member 114 function as bipolar electrodes.","The operation portion 170 is provided an operation portion main body 172, a stationary handle 174, a movable

a result, the first grasping member 112 and second grasping member 114 open or close relative to each other.","The output switch 178 includes, for example, two buttons.","These buttons are buttons which are pressed when high-frequency electric power is made to act on the biological tissue, which is the treatment target, by the treatment portion 110.The electric power source device 200, which detects the pressing of the button, applies a high-frequency voltage between the first grasping member 112 and second grasping member 114.As a result, the biological tissue, which is grasped by the

high-frequency treatment system 10 may be provided with both the output switch 178 and the footswitch 290, or may be provided with one of them.","Hereinafter, a description will be given on the assumption that the output switch 178 is mainly operated, but the footswitch 290 may be operated.","One end of a cable 180 is connected to the proximal side of the operation portion 170.The other end of the cable 180 is connected to the electric power source device 200.The electric power source device 200 controls the operation of the high-frequency treatment instrument 100, and supplies electric power to the high-frequency treatment instrument 100.FIG.","2 is a block diagram which schematically illustrates a configuration example of the electric power source device 200.The electric power source device 200 includes a control circuit 210, a high-frequency electric power source circuit 220, an output detection circuit 230, an A/D converter 240, a storage medium 250, an input device 262, a display 264, and a speaker 266.The control circuit 210 includes an integrated circuit or the like, such as a central processing unit (CPU), an application specific integrated circuit (ASIC), or a field programmable gate array (FPGA).","The control circuit 210 may be composed of a single integrated circuit or the like, or may be composed of a combination of a plurality of integrated circuits or the like.","The operation of the control circuit 210 is executed, for example, in accordance with a program stored in the control circuit 210 or in the storage medium 250.The control circuit 210 acquires information from each component of the electric power source device 200, and controls the operation of each component.","The high-frequency electric power source circuit 220 outputs high-frequency electric power which is supplied to the high-frequency treatment instrument 100.The high-frequency electric power source circuit 220 includes a variable DC electric power source 221, a waveform generating circuit 222, and an output circuit 223.The variable DC electric power source 221 outputs DC electric power under the control of the control circuit 210.The output of the variable DC electric power source 221 is transmitted to the output circuit 223.The waveform generating circuit 222 generates an AC waveform under the control of the control circuit 210, and outputs the generated AC waveform.","The output of the waveform generating circuit 222 is transmitted to the output circuit 223.The output circuit 223 superimposes the output of the variable DC electric power source 221 and the output of the waveform generating circuit 222, and outputs AC electric power.","This AC electric power is supplied, via the output detection circuit 230, to the first grasping member 112 and second grasping member 114 of the high-frequency treatment instrument 100.The output detection circuit 230 includes a current detection circuit 231 and a voltage detection circuit 232.The current detection circuit 231 is inserted in a circuit from the high-frequency electric power source circuit 220 to the high-frequency treatment instrument 100, and outputs an analog signal which represents a current value that is output from the high-frequency electric power source circuit 220.The voltage detection circuit 232 outputs an analog signal which represents an output voltage of the high-frequency electric power source circuit 220.The output signal of the current detection circuit 231 and the output signal of the voltage detection circuit 232 are input to the A/D converter 240.The A/D converter 240 converts the input analog signals to a digital signal, and sends the digital signal to the control circuit 210.In this manner, the control circuit 210 acquires information of the output voltage and output current of the high-frequency electric power source circuit 220.In addition, based on the output voltage and output current, the control circuit 210 calculates a value relating to an impedance of a circuit including the first grasping member 112, the biological tissue that is the treatment target, and the second grasping member 114.Specifically, the control circuit 210 acquires a value relating to the impedance of the biological tissue.","The storage medium 250 stores programs which are used in the control circuit 210, and various parameters, tables, etc.","which are used in calculations executed in the control circuit 210.The input device 262 includes an input device such as a button, a slider, a dial, a keyboard, or a touch panel.","The control circuit 210 acquires an input to the input device 262 by the user.","The display 264 includes a display device such as a liquid crystal display or an LED lamp.","The display 264 presents information relating to the high-frequency treatment system 10 to the user, under the control of the control circuit 210.The speaker 266 issues, for example, an input sound, an output sound, an alarm sound, etc., under the control of the control circuit 210.The operation of the high-frequency treatment system 10 according to the present embodiment will be described.","The user operates the input device 262 of the electric power source device 200, and sets a desired output level for the high-frequency treatment instrument 100.The output level is set, for example, for each of the plural output switches 178.The treatment portion 110 and shaft 160 are inserted, for example, into a peritoneal cavity through an abdominal wall.","The user opens or closes the treatment portion 110 by operating the movable handle 176.In this manner, the first grasping member 112 and second grasping member 114 grasp the biological tissue that is the treatment target.","When the biological tissue is grasped by the treatment portion 110, the user operates the output switch 178.The control circuit 210 of the electric power source device 200, which detected the pressing of the button of the output switch 178, outputs an instruction, which relates to driving, to the high-frequency electric power source circuit 220.The high-frequency electric power source circuit 220 applies, under the control of the control circuit 210, a high-frequency voltage to the first grasping member 112 and second grasping member 114 of the treatment portion 110, and causes a high-frequency current to flow through the biological tissue that is the treatment target.","If the high-frequency current flows, the biological tissue becomes an electrical resistance.","Thus, heat is generated in the biological tissue, and the temperature of the biological tissue rises.","As a result, the protein of the biological tissue is denatured, and the biological tissue is sealed.","By the above, the treatment of the biological tissue is completed.","The output operation of the electric power source device 200 will be described in detail.","The outline of the operation of the electric power source device 200 according to the present embodiment will be described with reference to a flowchart of FIG.","3.In step S101, the control circuit 210 determines whether the output switch 178 is turned on.","If the output switch 178 is not turned on, the process returns to step S101.In other words, the control circuit 210 stands by until the output switch 178 is turned on.","When the output switch 178 is turned on, the process advances to step S102.In step S102, the control circuit 210 executes first control.","Then, in step S103, the control circuit 210 executes second control.","Subsequently, in step S104, the control circuit 210 executes third control.","The first control, second control and third control will be described later in detail.","By the above, the output control is terminated.","In this manner, in the present embodiment, three-stage controls are executed.","Referring to FIG.","4, a description is given of an example of an output of the high-frequency treatment system 10 according to the embodiment, and an impedance relating to the biological tissue, which is calculated at the time of the output.","In FIG.","4, the horizontal axis indicates time, which is set such that an output start time is 0.The left vertical axis indicates an output electric power, an output voltage, and an output current.","The right vertical axis indicates an impedance.","In FIG.","4, a solid line indicates a variation of the output voltage, a dashed line indicates a variation of the impedance, a dashed-dotted line indicates a variation of the output electric power, and a dashed double-dotted line indicates a variation of the output current.","As described above, the control of the output of the high-frequency treatment system 10 according to the present embodiment is divided into three stages (three phases).","Accordingly, the period, during which electric power is supplied to the biological tissue, includes a first period in which the first control of a short period immediately after the output start is executed, a subsequent second period in which the second control of about one second is executed, and a subsequent third period in which the third control of about two seconds is executed.","The output by the first control is referred to as a first output, the output by the second control is referred to as a second output, and the output by the third control is referred to as a third output.","In addition, since the output by the second control is executed prior to the output by the third control, the period by the second control is referred to as a former period, and the period by the third control is referred to as a latter period.","In the first control, high-frequency electric power having a predetermined electric power value is supplied to the biological tissue during a predetermined period.","This first period is, for example, about 100 milliseconds.","During the first period, the value relating to the impedance is acquired.","In accordance with the size, kind, etc.","of the biological tissue that is the treatment target, or the state of the biological tissue, the value relating to the impedance, which is acquired at that time, will vary.","Thus, in the present embodiment, based on the value relating to the impedance which is acquired in the first period in which the first control is executed, the state of the biological tissue that is the treatment target is ascertained, and control parameters, which are used in the subsequent control, are determined.","Specifically, the control parameters, which correspond to the characteristics of the biological tissue that is the treatment target, are set.","In addition, in the first control, an overshoot of the output is suppressed by a predetermined electric power, which is not so large, being supplied to the biological tissue.","In the second control, a voltage which increases linearly is applied to the biological tissue.","The temperature of the biological tissue rises in the second period in which the second control is executed.","The second control is executed until it is detected that the value relating to the measured impedance takes a minimum value.","If the value relating to the measured impedance takes the minimum value, the control transitions to the third control.","If moisture evaporates in the second control, the value relating to the impedance increases subsequently in accordance with the rise in temperature.","In the third control, the output control is executed such that the value relating to the impedance increases linearly.","In this third period, the temperature of the biological tissue is kept substantially constant.","Hereinafter, the first to third controls will be described in detail.","[First Control] The first control will be described with reference to a flowchart illustrated in FIG.","5.In step S201, the control circuit 210 causes the high-frequency electric power source circuit 220 to supply AC electric power having a predetermined electric power value to the biological tissue that is the treatment target, which is clamped between the first grasping member 112 and second grasping member 114.By the supply of the AC electric power, an AC current flows through the biological tissue.","In step S202, the control circuit 210 acquires an impedance value relating to the biological tissue that is the treatment target.","For example, the control circuit 210 acquires the current detected by the current detection circuit 231 of the output detection circuit 230, and the voltage detected by the voltage detection circuit 232 of the output detection circuit 230, and calculates the impedance value based on these values.","Here, the calculated impedance value may be various kinds of values relating to the impedance, and may be, for example, an absolute value of the impedance which is a complex number, or may be a resistance value which is a real number component of the impedance.","An admittance, which is a reciprocal of the impedance, may be used.","In step S203, the control circuit 210 determines whether a predetermined time has passed.","Here, the predetermined time is, for example, 100 milliseconds.","If the predetermined time has not passed, the process returns to step S201.Specifically, the supply of the predetermined electric power and the acquisition of the impedance value are repeated.","When the predetermined time has passed, the first control ends, and a transition occurs to the second control.","The impedance value, which is acquired in the first control, is referred to as an initial impedance value.","The initial impedance value may be an impedance value which is first acquired, or may be a mean value or a median of impedance values acquired in some periods in the first period during which the first control is executed.","[Second Control] The second control will be described in detail.","The second control is a control which is optimized in order to stably seal a blood vessel or the like.","Here, attention is paid to a change of the impedance value at a time when the biological tissue, such as a blood vessel, is heated.","If the biological tissue is heated, the temperature of an electrolyte solution in the biological tissue rises, and the impedance decreases.","Paying attention to this decrease of the impedance, the following became clear.","FIG.","6 illustrates the relationship between duration of a voltage application (heating time) by the second control and a mean value of a vessel burst pressure (VBP).","Here, the duration of the voltage application by the second control is a time from when the second control started until when the impedance value takes the minimum value, as described above.","In addition, as described above and as illustrated in FIG.","4, the second control is a control in which the output voltage is adjusted so as to increases linearly.","The VBP indicates a pressure at which a sealed part is peeled when a water pressure is applied to the blood vessel after the seal treatment through the second control and third control.","Specifically, as the VBP becomes higher, this means that stronger sealing is performed.","In general, it is required that a VBP of 360 mmHg or above be obtained in the blood vessel after at least 90% or more of the treatment.","As illustrated in FIG.","6, the VBP tends to increase, as the time until the impedance value takes the minimum value becomes longer.","In addition, even when the time until the impedance value takes the minimum value increased to one second or more, the VBP did not increase so much.","Taking into account the result shown in FIG.","6 and the fact that a shorter treatment time is desired, it is considered that the time until the impedance value takes the minimum value should preferably be about one second.","It is understood that the time may be in a range of between about 0.5 seconds and 1.5 seconds, in which the VBP is sufficiently higher than 360 mmHg.","In consideration of these results, in the present embodiment, the output voltage in the second control is adjusted such that the time until the impedance value takes the minimum value becomes about one second.","In the present embodiment, the control circuit 210 controls the output voltage V(t) which is applied to the biological tissue in the second control, as indicated by the following equation (1): V(t)=(V(Z)/GV)×t, (1) where t is a time from the start of treatment, that is, a time from the start of the first control.","The time t may be a time from the start of the second control.","V(Z) is a constant, for example, a maximum value of the output voltage.","GV is a gradient value.","Thus, (V(Z)/GV) indicates an increase value of the output voltage per unit time, that is, an inclination (increase rate).","GV is determined based on the initial impedance value acquired in the first control.","For example, based on an initial resistance value R0, GV is determined by the following equation (2): GV=a·R0+b, (2) where a and b are fixed values.","The values a and b are empirically adjusted such that the impedance value takes the minimum value in about one second, when the output voltage V(t) is applied to the biological tissue.","The above equation (2) is not limited to an equation of a linear function, and may be another equation such as a function of a higher degree.","However, the linear function is preferable to a higher-degree function, so that the influence, which the initial resistance value R0 exerts on the above equation (1), may not become excessively large.","In addition, the above equation (1) is also a linear function relating to time.","Because of the linear function, a proper temperature rise with high stability can be obtained.","Since the output voltage is the linear function relating to time, the electric power, which is input to the biological tissue, increases in a manner of a quadratic function with respect to time.","An offset may be added to the output voltage V(t).","Specifically, the above equation (1) may be modified as follows: V(t)=(V(Z)/GV)×t+c, (3) where c is a fixed value.","According to the above equations (1) and (2), for example, in a thin blood vessel, the initial resistance value R0 is relatively high.","Thus, (V(Z)/GV), which indicates a gradient, is relatively small.","Specifically, in a thin blood vessel, the output voltage increases relatively slowly, and accordingly the input electric power increases relatively slowly.","On the other hand, for example, in a thick blood vessel, the initial resistance value R0 is relatively low.","Thus, (V(Z)/GV), which indicates the gradient, is relatively large.","Specifically, in a thick blood vessel, the output voltage increases relatively quickly, and accordingly the input electric power increases relatively quickly.","The gradient (V(Z)/GV) may be calculated at each time and used, based on the relationships of the above equations (1) and (2) and the initial resistance value R0, or may be determined based on the table prestored in the storage medium 250, which represents the relationship between the initial resistance value R0 and gradient (V(Z)/GV), and based on the initial resistance value.","The operation of the electric power source device 200 in the second control will be described with reference to a flowchart of FIG.","7.In step S301, the control circuit 210 calculates the relationship between time and output voltage V(t), based on the initial impedance value.","The output voltage V(t) is determined, for example, by using the above equations (1) and (2).","In step S302, the control circuit 210 causes the high-frequency electric power source circuit 220 to output the voltage V(t) which corresponds to time.","In step S303, the control circuit 210 acquires the impedance value of the biological tissue.","In step S304, the control circuit 210 determines whether the impedance value acquired in step S303 is a change-over impedance value or not.","Here, the change-over impedance value is an impedance value which is a condition for terminating the second control.","The change-over impedance value can be, for example, a value at a time when the variation of the impedance value is measured and the impedance value becomes the minimum value.","In order to easily detect the minimum value, a value, which has increased by a predetermined value after the impedance value took the minimum value, may be set as the change-over impedance value.","Specifically, in step S304, when the impedance value decreased and took the minimum value and then the impedance value has increased by the predetermined value, it may be determined that the impedance value has become the change-over impedance value.","In step S304, when it is determined that the impedance value is not the change-over impedance value, the process returns to step S302.On the other hand, when it is determined that the impedance value is the change-over impedance value, the second control is terminated, and a transition occurs to the third control.","By the above-described controls, the output voltage and the impedance value become as illustrated in FIG.","4.Specifically, in the second period in which the second control is executed, the output voltage increases linearly.","At this time, the output electric power increases in a manner of a quadratic function.","The impedance value acquired in the second period decreases slowly with time.","In the example illustrated in FIG.","4, when the impedance value has slightly increased after taking the minimum value, the second control is terminated.","In the meantime, although the example in which the output voltage is controlled is illustrated here, the output current or output electric power may be controlled so as to increase linearly in the same manner.","The time until the impedance value takes the minimum value is set to be about one second and is relatively slow.","It is thus possible to make unifoLitt the temperature of the biological tissue, while shortening the time of the treatment.","In addition, by setting the time until the impedance value takes the minimum value to be constant at about one second, regardless of the size, etc.","of the treatment target, it is possible to suppress a variance in results of treatments.","In the meantime, when the same energy is input, the impedance value takes the minimum value in a shorter time, as the thickness of the blood vessel becomes smaller.","By setting the time until the impedance value takes the minimum value to be about one second, a high sealing strength can be obtained stably, as illustrated in FIG.","6.","[Third Control] The third control will be described in detail.","In the third control, the output is controlled such that the measured impedance value increases with a constant rate.","In the present embodiment, a stop impedance value, which is an impedance value at a time when the output is stopped, is first determined.","Next, target impedance which increases at a constant speed from the impedance value at the start time of the third control up to the stop impedance value is set.","Specifically, the target impedance value is set as a target value of the impedance value at each time.","The control of the output is executed such that the output value is determined at predetermined time intervals, based on a difference between the target impedance value and a measured impedance value acquired by using the output detection circuit 230.In this manner, the third control is executed until the measured impedance value reaches the stop impedance value along target impedance values."," A determination method of the stop impedance value at the time of stopping the output will be described.","Here, a description is given of the case of using a resistance value as the impedance value.","The same applies to cases using other impedance values, aside from the resistance value.","A stop resistance value Rstop, which is a resistance value at the time of stopping the output, is calculated by, for example, the following equation (4): Rstop=Rin+Radd.","(4) Rin is a resistance value relating to the biological tissue, which is acquired at the start time of the third control.","Specifically, Rin is the resistance value corresponding to the above-described change-over impedance value.","The Rin may be the minimum impedance measured in the second control.","In addition, the initial impedance value acquired in the first control may be used for Rin.","Radd is an additional resistance value which is determined based on the initial state of the biological tissue.","Some examples of the determination method of the additional resistance value Radd will be illustrated.","(First Example) The additional resistance value Radd is calculated as a function of the initial resistance value R0.The initial resistance value R0 is the resistance value detected in the first control.","The storage medium 250 stores a table, for example, as illustrated in FIG.","8, the table representing the relationship between the additional resistance value Radd and initial resistance value R0.Based on this table and the initial resistance value R0 measured in the first control, the additional resistance value Radd is determined.","In FIG.","8, a, b, c and d represent resistance values, and have a relationship of a A setting method of the target impedance value will be described.","Here, a description is given of the case in which, like the above-described stop resistance value, the resistance value is used as the impedance value.","Specifically, the case in which a target resistance value is used as the target impedance value will be described.","The same applies to the cases of using other values relating to the impedance, aside from the resistance value.","(First Example) In a first example, a time in which high-frequency electric power is output by the third control is predetermined.","A target resistance value at each time can be set such that, in this predetermined time, the resistance value linearly increases up to the stop resistance value Rstop which is calculated from the change-over resistance value Rin.","(Second Example) In a second example, a time in which high-frequency electric power is output by the third control is determined in accordance with the output level that is set by the user.","A target resistance value can be set such that, in the time determined in accordance with the output level, the resistance value linearly increases up to the calculated stop resistance value Rstop.","Specifically, as illustrated in FIG.","10, an inclination at a time when the target resistance value is indicated relative to time varies in accordance with the output level.","In other words, the speed of increase of the target resistance value varies in accordance with the output level.","In FIG.","10, L1, L2 and L3 indicate output levels, and have a relationship of L1 A determination method of an output will be described.","Like the above-described case, the case in which a resistance value is used as the impedance value is described.","The same applies to the cases of using other values relating to the impedance, aside from the resistance value.","A description will be given with reference to FIG.","11.An upper part of FIG.","11 schematically illustrates a target resistance value and a measured resistance value relative to time.","Here, the target resistance value is indicated by a broken line, and the measured resistance value is indicated by a solid line.","A lower part of FIG.","11 schematically illustrates output electric power relative to time.","In the present embodiment, the output electric power is set in each step time of several-ten milliseconds.","The setting of the output electric power is executed by comparing the target resistance value and the measured resistance value.","Specifically, the target resistance value and the measured resistance value are compared at predetermined time intervals.","When the measured resistance value is higher than the target resistance value, the output electric power is decreased.","On the other hand, when the measured resistance value is lower than the target resistance value, the output electric power is increased.","In addition, when the difference between the measured resistance value and the target resistance value is less than a predetermined threshold value, the output electric power is maintained.","The output electric power at the start time of the third control may be the output electric power at the end time of the second control.","The output electric power at the start time of the third control may be a predetermined value, or may be determined by a predetermined method.","If the set value of the output electric power is frequently changed, there is concern that the output oscillates.","On the other hand, if the setting of the output electric power is executed only occasionally, the precision in control would lower, or the treatment could not be completed within a target time.","Thus, it is preferable that the interval of re-setting of output electric power, that is, the step time, is appropriately adjusted.","Examples of the determination method of the output electric power will be described.","(First Example) In a first example, a change amount of the output electric power is a predetermined ratio relative to the output electric power at that time point.","For example, this predetermined ratio is set as a first ratio.","In this case, when the initial output electric power is a first electric power, and the measured resistance value is higher than the target resistance value, the next output electric power is set at a second electric power which is lowered from the first electric power by the first ratio.","When the output is a second electric power, and the measured resistance value is lower than the target resistance value, the next output electric power is set at a third electric power which is raised from the second electric power by the first ratio.","Subsequently, the output electric power is controlled in the same manner.","For example, if the first ratio is set at 10%, the output electric power is controlled as follows.","When the output electric power is 20 W at that time point and the measured resistance value is higher than the target resistance value, the next output electric power is adjusted at 18 W. When the output electric power is 18 W and the measured resistance value is lower than the target resistance value, the next output electric power is adjusted at 19.8 W. By setting the change amount of the output electric power to be the predetermined ratio relative to the output electric power at that time point, the change amount is adjusted to a proper value at each of a time when the output electric power is large and a time when the output electric power is small.","The numerical values illustrated here are merely examples, and any numerical value can be used for the proper setting.","In the meantime, when the ratio at the time of lowering the output electric power is set as a first ratio and the ratio at the time of raising the output electric power is set as a second ratio, the first ratio and the second ratio may be equal or different.","It is preferable that the first ratio is greater than the second ratio.","For example, when the measured resistance value is higher than the target resistance value, the output is lowered by 10%.","When the measured resistance value is lower than the target resistance value, the output is raised by 5%.","In addition, when the difference between the measured resistance value and the target resistance value is within a predetermined range, the output electric power may not be changed.","(Second Example) In a second example, a change amount of the output electric power is a predetermined value.","In a case in which this predetermined ratio is set as a first value, when the measured resistance value is higher than the target resistance value, the next output electric power is adjusted at a value which is lowered from the present output electric power by a first value.","When the measured resistance value is lower than the target resistance value, the next output electric power is adjusted at a value which is higher than the present output electric power by the first value.","For example, when the change amount is set to be 2 W, the output electric power is controlled as follows.","When the output electric power is 20 W at that time point and the measured resistance value is higher than the target resistance value, the next output electric power is adjusted at 18 W. When the output electric power is 18 W and the measured resistance value is lower than the target resistance value, the next output electric power is adjusted at 20 W. By setting the change amount of the output electric power at a constant value, the hardware configuration becomes simpler, and the control of the output electric power becomes easier.","The numerical values illustrated here are merely examples, and any numerical value can be used for the proper setting.","In the meantime, the change amount at the time of raising the output and the change amount at the time of lowering the output may be equal or different.","It is preferable that the change amount at the time of lowering the output is greater than the change amount at the time of raising the output.","In addition, when the difference between the measured resistance value and the target resistance value is within a predetermined range, the output electric power may not be changed.","(Third Example) In a third example, a change amount of the output electric power is determined based on the initial resistance value R0 acquired in the first control, and the length of the second period in which the second control is executed, that is, the period from when the second control started until when the impedance values takes the minimum value.","Thus, the storage medium 250 prestores, for example, a relationship between the initial resistance value R0, the length of the second period, and the change amount of the output electric power.","The control circuit 210 determines the output electric power by referring to this relationship.","(Fourth Example) In a fourth example, a change amount of the output electric power is a predetermined value which is determined in accordance with an output level that is set by the user.","The storage medium 250 prestores a relationship between the output level and the change amount of the output electric power.","The control circuit 210 determines the output electric power by referring to this relationship.","(Fifth Example) In a fifth example, the output electric power is determined by the relationship between the measured resistance value and the target resistance value.","For example, the output electric power is set as follows.","When the measured resistance value is higher than the target resistance value, the output electric power is set at a first electric power value.","When the measured resistance value is equal to the target resistance value, the output electric power is set at a second electric power value.","When the measured resistance value is lower than the target resistance value, the output electric power is set at a third electric power value.","Here, the electric power values become greater in the order of the first electric power value, second electric power value and third electric power value.","For example, the first electric power value is 5 W, second electric power value is 8 W, and third electric power value is 10 W. The numerical values illustrated here are merely examples, and any numerical value can be used for the proper setting.","The third control, which is controlled in the above manner, will be described with reference to a flowchart of FIG.","12.In step S401, the control circuit 210 calculates the additional impedance value, based on the initial impedance value.","In step S402, the control circuit 210 sets the stop impedance value, based on the sum of the change-over impedance value and the additional impedance value.","For example, any of the methods of the above-described first to third examples may be used for the setting method of the stop impedance value.","In step S403, the control circuit 210 sets the target impedance value by using the stop impedance value.","Any of the methods

drawings.\",\n \"FIG.\",\n \"1 is a schematic view of a high-frequency treatment system 10 according to the present embodiment.\",\n \"As illustrated in this Figure, the high-frequency treatment system 10 includes a high-frequency treatment instrument 100 which functions as a high-frequency treatment instrument, an electric power source device 200 which supplies electric power to the treatment instrument, and a footswitch 290.The high-frequency treatment instrument 100 includes a treatment portion 110, a shaft 160, and an operation portion 170.For the purpose of descriptions below, the treatment portion 110 side is referred to as a distal side, and the operation portion 170 side is referred to as a proximal side.\",\n \"The high-frequency treatment system 10 is configured to grasp a biological tissue, such as a blood vessel, which is a treatment target, by the treatment portion 110.The high-frequency treatment system 10 applies a high-frequency voltage to the grasped biological tissue, thereby sealing this biological tissue.\",\n \"The treatment portion 110, which is provided at a distal end of the shaft 160, is provided with a first grasping member 112 and a second grasping member 114, which are a pair of grasping members.\",\n \"Those parts of the first grasping member 112 and second grasping member 114, which come in contact with the biological tissue, function as electrodes, respectively.\",\n \"Specifically, the first grasping member 112 and second grasping member 114 function as bipolar electrodes.\",\n \"The operation portion 170 is provided an operation portion main body 172, a stationary handle 174, a movable handle 176, and an output switch 178.The stationary handle 174 is fixed to the operation portion main body 172, and the movable handle 176 is displaced relative to the operation portion main body 172.The movable handle 176 is connected to a wire or a rod, which is inserted through the shaft 160.This wire or rod is connected to the second grasping member 114.The movement of the movable handle 176 is transmitted to the second grasping member 114.The second grasping member 114 is displaced relative to the first grasping member 112 in accordance with the movement of the movable handle 176.As a result, the first grasping member 112 and second grasping member 114 open or close relative to each other.\",\n \"The output switch 178 includes, for example, two buttons.\",\n \"These buttons are buttons which are pressed when high-frequency electric power is made to act on the biological tissue, which is the treatment target, by the treatment portion 110.The electric power source device 200, which detects the pressing of the button, applies a high-frequency voltage between the first grasping member 112 and second grasping member 114.As a result, the biological tissue, which is grasped by the treatment portion 110, is sealed.\",\n \"The high-frequency treatment instrument 100 is configured, for example, such that the output level varies depending on which of the two buttons is pressed.\",\n \"The footswitch 290 is also provided with, for example, two switches.\",\n \"The two respective switches of the footswitch 290 have the same functions as the respective buttons of the output switch 178.The high-frequency treatment system 10 may be provided with both the output switch 178 and the footswitch 290, or may be provided with one of them.\",\n \"Hereinafter, a description will be given on the assumption that the output switch 178 is mainly operated, but the footswitch 290 may be operated.\",\n \"One end of a cable 180 is connected to the proximal side of the operation portion 170.The other end of the cable 180 is connected to the electric power source device 200.The electric power source device 200 controls the operation of the high-frequency treatment instrument 100, and supplies electric power to the high-frequency treatment instrument 100.FIG.\",\n \"2 is a block diagram which schematically illustrates a configuration example of the electric power source device 200.The electric power source device 200 includes a control circuit 210, a high-frequency electric power source circuit 220, an output detection circuit 230, an A/D converter 240, a storage medium 250, an input device 262, a display 264, and a speaker 266.The control circuit 210 includes an integrated circuit or the like, such as a central processing unit (CPU), an application specific integrated circuit (ASIC), or a field programmable gate array (FPGA).\",\n \"The control circuit 210 may be composed of a single integrated circuit or the like, or may be composed of a combination of a plurality of integrated circuits or the like.\",\n \"The operation of the control circuit 210 is executed, for example, in accordance with a program stored in the control circuit 210 or in the storage medium 250.The control circuit 210 acquires information from each component of the electric power source device 200, and controls the operation of each component.\",\n \"The high-frequency electric power source circuit 220 outputs high-frequency electric power which is supplied to the high-frequency treatment instrument 100.The high-frequency electric power source circuit 220 includes a variable DC electric power source 221, a waveform generating circuit 222, and an output circuit 223.The variable DC electric power source 221 outputs DC electric power under the control of the control circuit 210.The output of the variable DC electric power source 221 is transmitted to the output circuit 223.The waveform generating circuit 222 generates an AC waveform under the control of the control circuit 210, and outputs the generated AC waveform.\",\n \"The output of the waveform generating circuit 222 is transmitted to the output circuit 223.The output circuit 223 superimposes the output of the variable DC electric power source 221 and the output of the waveform generating circuit 222, and outputs AC electric power.\",\n \"This AC electric power is supplied, via the output detection circuit 230, to the first grasping member 112 and second grasping member 114 of the high-frequency treatment instrument 100.The output detection circuit 230 includes a current detection circuit 231 and a voltage detection circuit 232.The current detection circuit 231 is inserted in a circuit from the high-frequency electric power source circuit 220 to the high-frequency treatment instrument 100, and outputs an analog signal which represents a current value that is output from the high-frequency electric power source circuit 220.The voltage detection circuit 232 outputs an analog signal which represents an output voltage of the high-frequency electric power source circuit 220.The output signal of the current detection circuit 231 and the output signal of the voltage detection circuit 232 are input to the A/D converter 240.The A/D converter 240 converts the input analog signals to a digital signal, and sends the digital signal to the control circuit 210.In this manner, the control circuit 210 acquires information of the output voltage and output current of the high-frequency electric power source circuit 220.In addition, based on the output voltage and output current, the control circuit 210 calculates a value relating to an impedance of a circuit including the first grasping member 112, the biological tissue that is the treatment target, and the second grasping member 114.Specifically, the control circuit 210 acquires a value relating to the impedance of the biological tissue.\",\n \"The storage medium 250 stores programs which are used in the control circuit 210, and various parameters, tables, etc.\",\n \"which are used in calculations executed in the control circuit 210.The input device 262 includes an input device such as a button, a slider, a dial, a keyboard, or a touch panel.\",\n \"The control circuit 210 acquires an input to the input device 262 by the user.\",\n \"The display 264 includes a display device such as a liquid crystal display or an LED lamp.\",\n \"The display 264 presents information relating to the high-frequency treatment system 10 to the user, under the control of the control circuit 210.The speaker 266 issues, for example, an input sound, an output sound, an alarm sound, etc., under the control of the control circuit 210.The operation of the high-frequency treatment system 10 according to the present embodiment will be described.\",\n \"The user operates the input device 262 of the electric power source device 200, and sets a desired output level for the high-frequency treatment instrument 100.The output level is set, for example, for each of the plural output switches 178.The treatment portion 110 and shaft 160 are inserted, for example, into a peritoneal cavity through an abdominal wall.\",\n \"The user opens or closes the treatment portion 110 by operating the movable handle 176.In this manner, the first grasping member 112 and second grasping member 114 grasp the biological tissue that is the treatment target.\",\n \"When the biological tissue is grasped by the treatment portion 110, the user operates the output switch 178.The control circuit 210 of the electric power source device 200, which detected the pressing of the button of the output switch 178, outputs an instruction, which relates to driving, to the high-frequency electric power source circuit 220.The high-frequency electric power source circuit 220 applies, under the control of the control circuit 210, a high-frequency voltage to the first grasping member 112 and second grasping member 114 of the treatment portion 110, and causes a high-frequency current to flow through the biological tissue that is the treatment target.\",\n \"If the high-frequency current flows, the biological tissue becomes an electrical resistance.\",\n \"Thus, heat is generated in the biological tissue, and the temperature of the biological tissue rises.\",\n \"As a result, the protein of the biological tissue is denatured, and the biological tissue is sealed.\",\n \"By the above, the treatment of the biological tissue is completed.\",\n \"The output operation of the electric power source device 200 will be described in detail.\",\n \"The outline of the operation of the electric power source device 200 according to the present embodiment will be described with reference to a flowchart of FIG.\",\n \"3.In step S101, the control circuit 210 determines whether the output switch 178 is turned on.\",\n \"If the output switch 178 is not turned on, the process returns to step S101.In other words, the control circuit 210 stands by until the output switch 178 is turned on.\",\n \"When the output switch 178 is turned on, the process advances to step S102.In step S102, the control circuit 210 executes first control.\",\n \"Then, in step S103, the control circuit 210 executes second control.\",\n \"Subsequently, in step S104, the control circuit 210 executes third control.\",\n \"The first control, second control and third control will be described later in detail.\",\n \"By the above, the output control is terminated.\",\n \"In this manner, in the present embodiment, three-stage controls are executed.\",\n \"Referring to FIG.\",\n \"4, a description is given of an example of an output of the high-frequency treatment system 10 according to the embodiment, and an impedance relating to the biological tissue, which is calculated at the time of the output.\",\n \"In FIG.\",\n \"4, the horizontal axis indicates time, which is set such that an output start time is 0.The left vertical axis indicates an output electric power, an output voltage, and an output current.\",\n \"The right vertical axis indicates an impedance.\",\n \"In FIG.\",\n \"4, a solid line indicates a variation of the output voltage, a dashed line indicates a variation of the impedance, a dashed-dotted line indicates a variation of the output electric power, and a dashed double-dotted line indicates a variation of the output current.\",\n \"As described above, the control of the output of the high-frequency treatment system 10 according to the present embodiment is divided into three stages (three phases).\",\n \"Accordingly, the period, during which electric power is supplied to the biological tissue, includes a first period in which the first control of a short period immediately after the output start is executed, a subsequent second period in which the second control of about one second is executed, and a subsequent third period in which the third control of about two seconds is executed.\",\n \"The output by the first control is referred to as a first output, the output by the second control is referred to as a second output, and the output by the third control is referred to as a third output.\",\n \"In addition, since the output by the second control is executed prior to the output by the third control, the period by the second control is referred to as a former period, and the period by the third control is referred to as a latter period.\",\n \"In the first control, high-frequency electric power having a predetermined electric power value is supplied to the biological tissue during a predetermined period.\",\n \"This first period is, for example, about 100 milliseconds.\",\n \"During the first period, the value relating to the impedance is acquired.\",\n \"In accordance with the size, kind, etc.\",\n \"of the biological tissue that is the treatment target, or the state of the biological tissue, the value relating to the impedance, which is acquired at that time, will vary.\",\n \"Thus, in the present embodiment, based on the value relating to the impedance which is acquired in the first period in which the first control is executed, the state of the biological tissue that is the treatment target is ascertained, and control parameters, which are used in the subsequent control, are determined.\",\n \"Specifically, the control parameters, which correspond to the characteristics of the biological tissue that is the treatment target, are set.\",\n \"In addition, in the first control, an overshoot of the output is suppressed by a predetermined electric power, which is not so large, being supplied to the biological tissue.\",\n \"In the second control, a voltage which increases linearly is applied to the biological tissue.\",\n \"The temperature of the biological tissue rises in the second period in which the second control is executed.\",\n \"The second control is executed until it is detected that the value relating to the measured impedance takes a minimum value.\",\n \"If the value relating to the measured impedance takes the minimum value, the control transitions to the third control.\",\n \"If moisture evaporates in the second control, the value relating to the impedance increases subsequently in accordance with the rise in temperature.\",\n \"In the third control, the output control is executed such that the value relating to the impedance increases linearly.\",\n \"In this third period, the temperature of the biological tissue is kept substantially constant.\",\n \"Hereinafter, the first to third controls will be described in detail.\",\n \"[First Control] The first control will be described with reference to a flowchart illustrated in FIG.\",\n \"5.In step S201, the control circuit 210 causes the high-frequency electric power source circuit 220 to supply AC electric power having a predetermined electric power value to the biological tissue that is the treatment target, which is clamped between the first grasping member 112 and second grasping member 114.By the supply of the AC electric power, an AC current flows through the biological tissue.\",\n \"In step S202, the control circuit 210 acquires an impedance value relating to the biological tissue that is the treatment target.\",\n \"For example, the control circuit 210 acquires the current detected by the current detection circuit 231 of the output detection circuit 230, and the voltage detected by the voltage detection circuit 232 of the output detection circuit 230, and calculates the impedance value based on these values.\",\n \"Here, the calculated impedance value may be various kinds of values relating to the impedance, and may be, for example, an absolute value of the impedance which is a complex number, or may be a resistance value which is a real number component of the impedance.\",\n \"An admittance, which is a reciprocal of the impedance, may be used.\",\n \"In step S203, the control circuit 210 determines whether a predetermined time has passed.\",\n \"Here, the predetermined time is, for example, 100 milliseconds.\",\n \"If the predetermined time has not passed, the process returns to step S201.Specifically, the supply of the predetermined electric power and the acquisition of the impedance value are repeated.\",\n \"When the predetermined time has passed, the first control ends, and a transition occurs to the second control.\",\n \"The impedance value, which is acquired in the first control, is referred to as an initial impedance value.\",\n \"The initial impedance value may be an impedance value which is first acquired, or may be a mean value or a median of impedance values acquired in some periods in the first period during which the first control is executed.\",\n \"[Second Control] The second control will be described in detail.\",\n \"The second control is a control which is optimized in order to stably seal a blood vessel or the like.\",\n \"Here, attention is paid to a change of the impedance value at a time when the biological tissue, such as a blood vessel, is heated.\",\n \"If the biological tissue is heated, the temperature of an electrolyte solution in the biological tissue rises, and the impedance decreases.\",\n \"Paying attention to this decrease of the impedance, the following became clear.\",\n \"FIG.\",\n \"6 illustrates the relationship between duration of a voltage application (heating time) by the second control and a mean value of a vessel burst pressure (VBP).\",\n \"Here, the duration of the voltage application by the second control is a time from when the second control started until when the impedance value takes the minimum value, as described above.\",\n \"In addition, as described above and as illustrated in FIG.\",\n \"4, the second control is a control in which the output voltage is adjusted so as to increases linearly.\",\n \"The VBP indicates a pressure at which a sealed part is peeled when a water pressure is applied to the blood vessel after the seal treatment through the second control and third control.\",\n \"Specifically, as the VBP becomes higher, this means that stronger sealing is performed.\",\n \"In general, it is required that a VBP of 360 mmHg or above be obtained in the blood vessel after at least 90% or more of the treatment.\",\n \"As illustrated in FIG.\",\n \"6, the VBP tends to increase, as the time until the impedance value takes the minimum value becomes longer.\",\n \"In addition, even when the time until the impedance value takes the minimum value increased to one second or more, the VBP did not increase so much.\",\n \"Taking into account the result shown in FIG.\",\n \"6 and the fact that a shorter treatment time is desired, it is considered that the time until the impedance value takes the minimum value should preferably be about one second.\",\n \"It is understood that the time may be in a range of between about 0.5 seconds and 1.5 seconds, in which the VBP is sufficiently higher than 360 mmHg.\",\n \"In consideration of these results, in the present embodiment, the output voltage in the second control is adjusted such that the time until the impedance value takes the minimum value becomes about one second.\",\n \"In the present embodiment, the control circuit 210 controls the output voltage V(t) which is applied to the biological tissue in the second control, as indicated by the following equation (1): V(t)=(V(Z)/GV)×t, (1) where t is a time from the start of treatment, that is, a time from the start of the first control.\",\n \"The time t may be a time from the start of the second control.\",\n \"V(Z) is a constant, for example, a maximum value of the output voltage.\",\n \"GV is a gradient value.\",\n \"Thus, (V(Z)/GV) indicates an increase value of the output voltage per unit time, that is, an inclination (increase rate).\",\n \"GV is determined based on the initial impedance value acquired in the first control.\",\n \"For example, based on an initial resistance value R0, GV is determined by the following equation (2): GV=a·R0+b, (2) where a and b are fixed values.\",\n \"The values a and b are empirically adjusted such that the impedance value takes the minimum value in about one second, when the output voltage V(t) is applied to the biological tissue.\",\n \"The above equation (2) is not limited to an equation of a linear function, and may be another equation such as a function of a higher degree.\",\n \"However, the linear function is preferable to a higher-degree function, so that the influence, which the initial resistance value R0 exerts on the above equation (1), may not become excessively large.\",\n \"In addition, the above equation (1) is also a linear function relating to time.\",\n \"Because of the linear function, a proper temperature rise with high stability can be obtained.\",\n \"Since the output voltage is the linear function relating to time, the electric power, which is input to the biological tissue, increases in a manner of a quadratic function with respect to time.\",\n \"An offset may be added to the output voltage V(t).\",\n \"Specifically, the above equation (1) may be modified as follows: V(t)=(V(Z)/GV)×t+c, (3) where c is a fixed value.\",\n \"According to the above equations (1) and (2), for example, in a thin blood vessel, the initial resistance value R0 is relatively high.\",\n \"Thus, (V(Z)/GV), which indicates a gradient, is relatively small.\",\n \"Specifically, in a thin blood vessel, the output voltage increases relatively slowly, and accordingly the input electric power increases relatively slowly.\",\n \"On the other hand, for example, in a thick blood vessel, the initial resistance value R0 is relatively low.\",\n \"Thus, (V(Z)/GV), which indicates the gradient, is relatively large.\",\n \"Specifically, in a thick blood vessel, the output voltage increases relatively quickly, and accordingly the input electric power increases relatively quickly.\",\n \"The gradient (V(Z)/GV) may be calculated at each time and used, based on the relationships of the above equations (1) and (2) and the initial resistance value R0, or may be determined based on the table prestored in the storage medium 250, which represents the relationship between the initial resistance value R0 and gradient (V(Z)/GV), and based on the initial resistance value.\",\n \"The operation of the electric power source device 200 in the second control will be described with reference to a flowchart of FIG.\",\n \"7.In step S301, the control circuit 210 calculates the relationship between time and output voltage V(t), based on the initial impedance value.\",\n \"The output voltage V(t) is determined, for example, by using the above equations (1) and (2).\",\n \"In step S302, the control circuit 210 causes the high-frequency electric power source circuit 220 to output the voltage V(t) which corresponds to time.\",\n \"In step S303, the control circuit 210 acquires the impedance value of the biological tissue.\",\n \"In step S304, the control circuit 210 determines whether the impedance value acquired in step S303 is a change-over impedance value or not.\",\n \"Here, the change-over impedance value is an impedance value which is a condition for terminating the second control.\",\n \"The change-over impedance value can be, for example, a value at a time when the variation of the impedance value is measured and the impedance value becomes the minimum value.\",\n \"In order to easily detect the minimum value, a value, which has increased by a predetermined value after the impedance value took the minimum value, may be set as the change-over impedance value.\",\n \"Specifically, in step S304, when the impedance value decreased and took the minimum value and then the impedance value has increased by the predetermined value, it may be determined that the impedance value has become the change-over impedance value.\",\n \"In step S304, when it is determined that the impedance value is not the change-over impedance value, the process returns to step S302.On the other hand, when it is determined that the impedance value is the change-over impedance value, the second control is terminated, and a transition occurs to the third control.\",\n \"By the above-described controls, the output voltage and the impedance value become as illustrated in FIG.\",\n \"4.Specifically, in the second period in which the second control is executed, the output voltage increases linearly.\",\n \"At this time, the output electric power increases in a manner of a quadratic function.\",\n \"The impedance value acquired in the second period decreases slowly with time.\",\n \"In the example illustrated in FIG.\",\n \"4, when the impedance value has slightly increased after taking the minimum value, the second control is terminated.\",\n \"In the meantime, although the example in which the output voltage is controlled is illustrated here, the output current or output electric power may be controlled so as to increase linearly in the same manner.\",\n \"The time until the impedance value takes the minimum value is set to be about one second and is relatively slow.\",\n \"It is thus possible to make unifoLitt the temperature of the biological tissue, while shortening the time of the treatment.\",\n \"In addition, by setting the time until the impedance value takes the minimum value to be constant at about one second, regardless of the size, etc.\",\n \"of the treatment target, it is possible to suppress a variance in results of treatments.\",\n \"In the meantime, when the same energy is input, the impedance value takes the minimum value in a shorter time, as the thickness of the blood vessel becomes smaller.\",\n \"By setting the time until the impedance value takes the minimum value to be about one second, a high sealing strength can be obtained stably, as illustrated in FIG.\",\n \"6.\",\n \"[Third Control] The third control will be described in detail.\",\n \"In the third control, the output is controlled such that the measured impedance value increases with a constant rate.\",\n \"In the present embodiment, a stop impedance value, which is an impedance value at a time when the output is stopped, is first determined.\",\n \"Next, target impedance which increases at a constant speed from the impedance value at the start time of the third control up to the stop impedance value is set.\",\n \"Specifically, the target impedance value is set as a target value of the impedance value at each time.\",\n \"The control of the output is executed such that the output value is determined at predetermined time intervals, based on a difference between the target impedance value and a measured impedance value acquired by using the output detection circuit 230.In this manner, the third control is executed until the measured impedance value reaches the stop impedance value along target impedance values.\",\n \" A determination method of the stop impedance value at the time of stopping the output will be described.\",\n \"Here, a description is given of the case of using a resistance value as the impedance value.\",\n \"The same applies to cases using other impedance values, aside from the resistance value.\",\n \"A stop resistance value Rstop, which is a resistance value at the time of stopping the output, is calculated by, for example, the following equation (4): Rstop=Rin+Radd.\",\n \"(4) Rin is a resistance value relating to the biological tissue, which is acquired at the start time of the third control.\",\n \"Specifically, Rin is the resistance value corresponding to the above-described change-over impedance value.\",\n \"The Rin may be the minimum impedance measured in the second control.\",\n \"In addition, the initial impedance value acquired in the first control may be used for Rin.\",\n \"Radd is an additional resistance value which is determined based on the initial state of the biological tissue.\",\n \"Some examples of the determination method of the additional resistance value Radd will be illustrated.\",\n \"(First Example) The additional resistance value Radd is calculated as a function of the initial resistance value R0.The initial resistance value R0 is the resistance value detected in the first control.\",\n \"The storage medium 250 stores a table, for example, as illustrated in FIG.\",\n \"8, the table representing the relationship between the additional resistance value Radd and initial resistance value R0.Based on this table and the initial resistance value R0 measured in the first control, the additional resistance value Radd is determined.\",\n \"In FIG.\",\n \"8, a, b, c and d represent resistance values, and have a relationship of a A setting method of the target impedance value will be described.\",\n \"Here, a description is given of the case in which, like the above-described stop resistance value, the resistance value is used as the impedance value.\",\n \"Specifically, the case in which a target resistance value is used as the target impedance value will be described.\",\n \"The same applies to the cases of using other values relating to the impedance, aside from the resistance value.\",\n \"(First Example) In a first example, a time in which high-frequency electric power is output by the third control is predetermined.\",\n \"A target resistance value at each time can be set such that, in this predetermined time, the resistance value linearly increases up to the stop resistance value Rstop which is calculated from the change-over resistance value Rin.\",\n \"(Second Example) In a second example, a time in which high-frequency electric power is output by the third control is determined in accordance with the output level that is set by the user.\",\n \"A target resistance value can be set such that, in the time determined in accordance with the output level, the resistance value linearly increases up to the calculated stop resistance value Rstop.\",\n \"Specifically, as illustrated in FIG.\",\n \"10, an inclination at a time when the target resistance value is indicated relative to time varies in accordance with the output level.\",\n \"In other words, the speed of increase of the target resistance value varies in accordance with the output level.\",\n \"In FIG.\",\n \"10, L1, L2 and L3 indicate output levels, and have a relationship of L1 A determination method of an output will be described.\",\n \"Like the above-described case, the case in which a resistance value is used as the impedance value is described.\",\n \"The same applies to the cases of using other values relating to the impedance, aside from the resistance value.\",\n \"A description will be given with reference to FIG.\",\n \"11.An upper part of FIG.\",\n \"11 schematically illustrates a target resistance value and a measured resistance value relative to time.\",\n \"Here, the target resistance value is indicated by a broken line, and the measured resistance value is indicated by a solid line.\",\n \"A lower part of FIG.\",\n \"11 schematically illustrates output electric power relative to time.\",\n \"In the present embodiment, the output electric power is set in each step time of several-ten milliseconds.\",\n \"The setting of the output electric power is executed by comparing the target resistance value and the measured resistance value.\",\n \"Specifically, the target resistance value and the measured resistance value are compared at predetermined time intervals.\",\n \"When the measured resistance value is higher than the target resistance value, the output electric power is decreased.\",\n \"On the other hand, when the measured resistance value is lower than the target resistance value, the output electric power is increased.\",\n \"In addition, when the difference between the measured resistance value and the target resistance value is less than a predetermined threshold value, the output electric power is maintained.\",\n \"The output electric power at the start time of the third control may be the output

bioavailability is a significant problem encountered in the development of therapeutic compositions, particularly those materials containing a biologically active material that is poorly soluble in water at physiological pH.","An active material's bioavailability is the degree to which the active material becomes available to the target tissue in the body after systemic administration through, for example, oral or intravenous means.","Many factors affect bioavailability, including the form of dosage and the solubility and dissolution rate of the active material.","Poorly and slowly water-soluble materials tend to be eliminated from the gastrointestinal tract before being absorbed into the circulation.","In addition, poorly soluble active agents tend to be disfavored or even unsafe for intravenous administration due to the risk of particles of agent blocking blood flow through capillaries.","It is known that the rate of dissolution of a particulate drug will increase with increasing surface area.","One way of increasing surface area is decreasing particle size.","Consequently, methods of making finely divided or sized drugs have been studied with a view to controlling the size and size range of drug particles for pharmaceutical compositions.","For example, dry milling techniques have been used to reduce particle size and hence influence drug absorption.","However, in conventional dry milling the limit of fineness is reached generally in the region of about 100 microns (100,000 nm), at which point material cakes on the milling chamber and prevents any further diminution of particle size.","Alternatively, wet grinding may be employed to reduce particle size, but flocculation restricts the lower particle size limit to approximately 10 microns (10,000 nm).","The wet milling process, however, is prone to contamination, thereby leading to a bias in the pharmaceutical art against wet milling.","Another alternative milling technique, commercial airjet milling, has provided particles ranging in average size from as low as about 1 to about 50 microns (1,000-50,000 nm).","There are several approaches currently used to formulate poorly soluble active agents.","One approach is to prepare the active agent as a soluble salt.","Where this approach cannot be employed, alternate (usually physical) approaches are employed to improve the solubility of the active agent.","Alternate approaches generally subject the active agent to physical conditions that change the agent's physical and or chemical properties to improve its solubility.","These include process technologies such as micronization, modification of crystal or polymorphic structure, development of oil based solutions, use of co-solvents, surface stabilizers or complexing agents, micro-emulsions, super critical fluid and production of solid dispersions or solutions.","More than one of these processes may be used in combination to improve formulation of a particular therapeutic material.","Many of these approaches commonly convert a drug into an amorphous state, which generally leads to a higher dissolution rate.","However, formulation approaches that result in the production of amorphous material are not common in commercial formulations due to concerns relating to stability and the potential for material to re-crystallize.","These techniques for preparing such pharmaceutical compositions tend to be complex.","By way of example, a principal technical difficulty encountered with emulsion polymerization is the removal of contaminants, such as unreacted monomers or initiators (which may have undesirable levels of toxicity), at the end of the manufacturing process.","Another method of providing reduced particle size is the formation of pharmaceutical drug microcapsules, which techniques include micronizing, polymerisation and co-dispersion.","However, these techniques suffer from a number of disadvantages including at least the inability to produce sufficiently small particles such as those obtained by milling, and the presence of co-solvents and/or contaminants such as toxic monomers which are difficult to remove, leading to expensive manufacturing processes.","Over the last decade, intense scientific investigation has been carried out to improve the solubility of active agents by converting the agents to ultra fine powders by methods such as milling and grinding.","These techniques may be used to increase the dissolution rate of a particulate solid by increasing the overall surface area and decreasing the mean particle size.","U.S. Pat.","No.","6,634,576 discloses examples of wet-milling a solid substrate, such as a pharmaceutically active compound, to produce a “synergetic co-mixture”.","International Patent Application PCT/AU2005/001977 (Nanoparticle Composition(s) and Method for Synthesis Thereof) describes, inter alia, a method comprising the step of contacting a precursor compound with a co-reactant under mechanochemical synthesis conditions wherein a solid-state chemical reaction between the precursor compound and the co-reactant produces therapeutically active nanoparticles dispersed in a carrier matrix.","Mechanochemical synthesis, as discussed in International Patent Application PCT/AU2005/001977, refers to the use of mechanical energy to activate, initiate or promote a chemical reaction, a crystal structure transformation or a phase change in a material or a mixture of materials, for example by agitating a reaction mixture in the presence of a milling media to transfer

nanoparticles.","For some drugs that require a high dose this limitation may restrict the options available for the production of a commercially viable dosage form.","The present invention provides methods for improving the dissolution profile of a biologically active material which ameliorate some of the problems attendant with prior technologies, or provides an alternative thereto.","One example of a therapeutic area where this technology could be applied in is the area of acute pain management.","Many pain medications such as meloxicam (marketed as Mobic® by pharmaceutical company Boehringer Ingelheim) provides pain relief for chronic pain, but must be taken on a daily basis to maintain an effective therapeutic level.","Meloxicam is a poorly water soluble drug which is only slowly absorbed by the body (Tmax is 4-5 hours), so a method such as the present invention which provides for improved dissolution, will likely provide much faster absorption resulting in a more rapid onset of the therapeutic effect.","Meloxicam also has a long half life (15-20 hours) that means it only need be taken once a day.","By using a method such as the present invention, which provides faster absorption, a drug such as meloxicam, could be transformed from a chronic pain drug to an acute pain drug.","For meloxicam this would provide a medication that could provide therapeutic relief for acute pain, with the advantage of sustained pain relief over 24 hours.","Meloxicam also has sub-optimal bioavailability at 89% for an oral capsule, compared with an IV dosage form.","A component of this sub optimal bioavailability is also likely due to the poor water solubility of this drug.","If the low solubility does contribute to this sub optimal bioavailability, the improvement of the dissolution of this drug with a method such as the present invention could provide scope to produce a dosage form with a lower active dose whilst still providing the effective therapeutic dose.","Although the background to the present invention is discussed in the context of improving the bioavailability of materials that are poorly or slowly water soluble, the applications of the methods of the present invention are not limited to such, as is evident from the following description of the invention.","Further, although the background to the present invention is largely discussed in the context of improving the bioavailability of therapeutic or pharmaceutical compounds, the applications of the methods of the present invention are clearly not limited to such.","For example, as is evident from the following description, applications of the methods of the present invention include but are not limited to: nutraceutical and nutritional compounds, complementary

applied to, but not limited to, a range of natural products such as seeds, cocoa and cocoa solids, coffee, herbs, spices, other plant materials or food materials that contain a biologically active

method of invention are formulated to produce suspensions of the actives when added to water or other solvents.","As these suspensions will have particles of very small size and high surface area they will possess at least three highly desirable traits.","The first is that small particles with high surface area will adhere better to surfaces such as leafs and other foliage that the suspension is applied to.","This will result in better rain fastness and a longer period of activity.","The second aspect is that smaller particles with a higher surface area deliver superior coverage per unit mass of active applied.","For example, if 100 particles are needed on a leaf and if the particle diameter is reduced to one third of the former diameter by the methods of this invention, then the dosage can be reduced to about 11% of the former dosage, resulting in lower cost, less residue on harvested crops, and mitigation of environmental impact.","In the third aspect the smaller particles will deliver better bioavailability.","With many low solubility actives, such as fungicides and pesticides the particles that adhere to plant material slowly dissolve over days and weeks providing continued protection from disease and pests.","With this method of invention able to deliver better bioavailability in many circumstances it will be possible to reduce the amount of active that needs to be applied.","As with the second aspect such an outcome would lower costs, minimize residues and mitigate environmental impact.","In a highly preferred aspect of the invention the powder produced in the milling process would be subject to a process such as wet or dry granulation that makes the powder free flowing and low in dust content yet easily dispersible once in water or other

reference.","FIELD OF THE INVENTION The present invention relates to methods for improving the dissolution profile of a biologically active material.","The invention also relates to biologically active materials in particulate form produced by said methods, compositions comprising such materials, medicaments produced using said biologically active materials in particulate form and/or compositions, and to methods of treatment of an animal, including man, using a therapeutically effective amount of said biologically active materials administered by way of said medicaments.","BACKGROUND Poor bioavailability is a significant problem encountered in the development of therapeutic compositions, particularly those materials containing a biologically active material that is poorly soluble in water at physiological pH.","An active material's bioavailability is the degree to which the active material becomes available to the target tissue in the body after systemic administration through, for example, oral or intravenous means.","Many factors affect bioavailability, including the form of dosage and the solubility and dissolution rate of the active material.","Poorly and slowly water-soluble materials tend to be eliminated from the gastrointestinal tract before being absorbed into the circulation.","In addition, poorly soluble active agents tend to be disfavored or even unsafe for intravenous administration due to the risk of particles of agent blocking blood flow through capillaries.","It is known that the rate of dissolution of a particulate drug will increase with increasing surface area.","One way of increasing surface area is decreasing particle size.","Consequently, methods of making finely divided or sized drugs have been studied with a view to controlling the size and size range of drug particles for pharmaceutical compositions.","For example, dry milling techniques have been used to reduce particle size and hence influence drug absorption.","However, in conventional dry milling the limit of fineness is reached generally in the region of about 100 microns (100,000 nm), at which point material cakes on the milling chamber and prevents any further diminution of particle size.","Alternatively, wet grinding may be employed to reduce particle size, but flocculation restricts the lower particle size limit to approximately 10 microns (10,000 nm).","The wet milling process, however, is prone to contamination, thereby leading to a bias in the pharmaceutical art against wet milling.","Another alternative milling technique, commercial airjet milling, has provided particles ranging in average size from as low as about 1 to about 50 microns (1,000-50,000 nm).","There are several approaches currently used to formulate poorly soluble active agents.","One approach is to prepare the active agent as a soluble salt.","Where this approach cannot be employed, alternate (usually physical) approaches are employed to improve the solubility of the active agent.","Alternate approaches generally subject the active agent to physical conditions that change the agent's physical and or chemical properties to improve its solubility.","These include process technologies such as micronization, modification of crystal or polymorphic structure, development of oil based solutions, use of co-solvents, surface stabilizers or complexing agents, micro-emulsions, super critical fluid and production of solid dispersions or solutions.","More than one of these processes may be used in combination to improve formulation of a particular therapeutic material.","Many of these approaches commonly convert a drug into an amorphous state, which generally leads to a higher dissolution rate.","However, formulation approaches that result in the production of amorphous material are not common in commercial formulations due to concerns relating to stability and the potential for material to re-crystallize.","These techniques for preparing such pharmaceutical compositions tend to be complex.","By way of example, a principal technical difficulty encountered with emulsion polymerization is the removal of contaminants, such as unreacted monomers or initiators (which may have undesirable levels of toxicity), at the end of the manufacturing process.","Another method of providing reduced particle size is the formation of pharmaceutical drug microcapsules, which techniques include micronizing, polymerisation and co-dispersion.","However, these techniques suffer from a number of disadvantages including at least the inability to produce sufficiently small particles such as those obtained by milling, and the presence of co-solvents and/or contaminants such as toxic monomers which are difficult to remove, leading to expensive manufacturing processes.","Over the last decade, intense scientific investigation has been carried out to improve the solubility of active agents by converting the agents to ultra fine powders by methods such as milling and grinding.","These techniques may be used to increase the dissolution rate of a particulate solid by increasing the overall surface area and decreasing the mean particle size.","U.S. Pat.","No.","6,634,576 discloses examples of wet-milling a solid substrate, such as a pharmaceutically active compound, to produce a “synergetic co-mixture”.","International Patent Application PCT/AU2005/001977 (Nanoparticle Composition(s) and Method for Synthesis Thereof) describes, inter alia, a method comprising the step of contacting a precursor compound with a co-reactant under mechanochemical synthesis conditions wherein a solid-state chemical reaction between the precursor compound and the co-reactant produces therapeutically active nanoparticles dispersed in a carrier matrix.","Mechanochemical synthesis, as discussed in International Patent Application PCT/AU2005/001977, refers to the use of mechanical energy to activate, initiate or promote a chemical reaction, a crystal structure transformation or a phase change in a material or a mixture of materials, for example by agitating a reaction mixture in the presence of a milling media to transfer mechanical energy to the reaction mixture, and includes without limitation “mechanochemical activation”, “mechanochemical processing”, “reactive milling”, and related processes.","International Patent Application PCT/AU2007/000910 (Methods for the preparation of biologically active compounds in nanoparticulate form) describes, inter alia, a method for dry milling raloxifene with lactose and NaCl which produced nanoparticulate raloxifene without significant aggregation problems.","One limitation of this method is an upper limit to the drug content that can be successfully milled to produce nanoparticles.","For some drugs that require a high dose this limitation may restrict the options available for the production of a commercially viable dosage form.","The present invention provides methods for improving the dissolution profile of a biologically active material which ameliorate some of the problems attendant with prior technologies, or provides an alternative thereto.","One example of a therapeutic area where this technology could be applied in is the area of acute pain management.","Many pain medications such as meloxicam (marketed as Mobic® by pharmaceutical company Boehringer Ingelheim) provides pain relief for chronic pain, but must be taken on a daily basis to maintain an effective therapeutic level.","Meloxicam is a poorly water soluble drug which is only slowly absorbed by the body (Tmax is 4-5 hours), so a method such as the present invention which provides for improved dissolution, will likely provide much faster absorption resulting in a more rapid onset of the therapeutic effect.","Meloxicam also has a long half life (15-20 hours) that means it only need be taken once a day.","By using a method such as the present invention, which provides faster absorption, a drug such as meloxicam, could be transformed from a chronic pain drug to an acute pain drug.","For meloxicam this would provide a medication that could provide therapeutic relief for acute pain, with the advantage of sustained pain relief over 24 hours.","Meloxicam also has sub-optimal bioavailability at 89% for an oral capsule, compared with an IV dosage form.","A component of this sub optimal bioavailability is also likely due to the poor water solubility of this drug.","If the low solubility does contribute to this sub optimal bioavailability, the improvement of the dissolution of this drug with a method such as the present invention could provide scope to produce a dosage form with a lower active dose whilst still providing the effective therapeutic dose.","Although the background to the present invention is discussed in the context of improving the bioavailability of materials that are poorly or slowly water soluble, the applications of the methods of the present invention are not limited to such, as is evident from the following description of the invention.","Further, although the background to the present invention is largely discussed in the context of improving the bioavailability of therapeutic or pharmaceutical compounds, the applications of the methods of the present invention are clearly not limited to such.","For example, as is evident from the following description, applications of the methods of the present invention include but are not limited to: nutraceutical and nutritional compounds, complementary medicinal compounds, veterinary therapeutic applications and agricultural chemical applications, such as pesticide, fungicide or herbicide.","Furthermore, an application of the current invention would be to materials which contain a biologically active compound such as, but not limited to a therapeutic or pharmaceutical compound, a nutraceutical or nutrient, a complementary medicinal product such as active components in plant or other naturally occurring material, a veterinary therapeutic compound or an agricultural compound such as a pesticide, fungicide or herbicide.","Specific examples would be the spice turmeric that contains the active compound curcumin, or flax seed that contains the nutrient ALA an omega-3 fatty acid.","As these specific examples indicate this invention could be applied to, but not limited to, a range of natural products such as seeds, cocoa and cocoa solids, coffee, herbs, spices, other plant materials or food materials that contain a biologically active compound.","The application of this invention to these types of materials would enable greater availability of the active compound in the materials when used in the relevant application.","For example where material subject to this invention is orally ingested the active would be more bioavailable.","SUMMARY OF THE INVENTION In one aspect the present invention is directed to the unexpected finding that the dissolution profile of biologically active materials can be improved by dry milling solid biologically active material to a particle size of greater than 1 μm.","In one surprising aspect of the invention, the dissolution profile of a biologically active material can be improved without substantially reducing the particle size of the material or reducing the material to nanoparticulate form.","In another surprising aspect of the invention, the material retains its crystalline structure and is not amorphous, yet the dissolution

area.","Such powders would provide better performance in areas such as seed treatment where dry powders are applied to seeds as fungicides, herbicide safeners, plant growth regulators and other treatments.","The higher surface area would provide more activity per mass of active used.","In another preferred aspect actives such as pesticides, fungicides and seed treatments subject to the method of invention are formulated to produce suspensions of the actives when added to water or other solvents.","As these suspensions will have particles of very small size and high surface area they will possess at least three highly desirable traits.","The first is that small particles with high surface area will adhere better to surfaces such as leafs and other foliage that the suspension is applied to.","This will result in better rain fastness and a longer period of activity.","The second aspect is that smaller particles with a higher surface area deliver superior coverage per unit mass of active applied.","For example, if 100 particles are needed on a leaf and if the particle diameter is reduced to one third of the former diameter by the methods of this invention, then the dosage can be reduced to about 11% of the former dosage, resulting in lower cost, less residue on harvested crops, and mitigation of environmental impact.","In the third aspect the smaller particles will deliver better bioavailability.","With many low solubility actives, such as fungicides and pesticides the particles that adhere to plant material slowly dissolve over days and weeks providing continued protection from disease and pests.","With this method of invention able to deliver better bioavailability in many circumstances it will be possible to reduce the amount of active that needs to be applied.","As with the second aspect such an outcome would lower costs, minimize residues and mitigate environmental impact.","In a highly preferred aspect of the invention the powder produced in the milling process would be subject to a process such as wet or dry granulation that makes the powder free flowing and low in dust content yet easily dispersible once in water or other solvent.","Preferably the biologically active material is a herbicide, pesticide, seed treatment, herbicide safener, plant growth regulator or fungicide selected from the group consisting of:

described herein, which are intended for the purpose of exemplification only.","Functionally equivalent products, compositions and methods are clearly within the scope of the invention as described herein.","The invention described herein may include one or more ranges of values (e.g.","size, concentration etc).","A range of values will be understood to include all values within the range, including the values defining the range, and values adjacent to the range that lead to the same or substantially the same outcome as the values immediately adjacent to that value which defines the boundary to the range.","The entire disclosures of all publications (including patents, patent applications, journal articles, laboratory manuals, books, or other documents) cited herein are hereby incorporated by reference.","Inclusion does not constitute an admission is made that any of the references constitute prior art or are part of the common general knowledge of those working in the field to which this invention relates.","Throughout this specification, unless the context requires otherwise, the word “comprise” or variations, such as “comprises” or “comprising” will be understood to imply the inclusion of a stated integer, or group of integers, but not the exclusion of any other integers or group of integers.","It is also noted that in this disclosure, and particularly in the claims and/or paragraphs, terms such as “comprises”, “comprised”, “comprising” and the like can have the meaning attributed to it in US patent law; e.g., they can mean “includes”, “included”, “including”, and the like.","“Therapeutically effective amount” as used herein with respect to methods of treatment and in particular drug dosage, shall mean that dosage that provides the specific pharmacological response for which the drug is administered in a significant number of subjects in need of such treatment.","It is emphasized that “therapeutically effective amount,” administered to a particular subject in a particular instance will not always be effective in treating the diseases described herein, even though such dosage is deemed a “therapeutically effective amount” by those skilled in the art.","It is to be further understood that drug dosages are, in particular instances, measured as oral dosages, or with reference to drug levels as measured in blood.","The term “inhibit” is defined to include its generally accepted meaning which includes prohibiting, preventing, restraining, and lowering, stopping, or reversing progression or severity, and such action on a resultant symptom.","As such the present invention includes both medical therapeutic and prophylactic administration, as appropriate.","The term “biologically active material” is defined to mean a biologically active compound or a substance which comprises a biologically active compound.","In this definition, a compound is generally taken to mean a distinct chemical entity where a chemical formula or formulas can be used to describe the substance.","Such compounds would generally, but not necessarily be identified in the literature by a unique classification system such as a CAS number.","Some compounds may be more complex and have a mixed chemical structure.","For such compounds they may only have a empirical formula or be qualitatively identified.","A compound would generally be a pure material, although it would be expected that up to 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% of the substance could be other impurities and the like.","Examples of biologically active compounds are, but not limited to, pharmaceutical actives, fungicides, pesticides, herbicides, nutraceuticals, cosmeceuticals, cosmetics, complementary medicines, natural products, vitamins, nutrients, biologics, amino acids, proteins, peptides, nucleotides, nucleic acids.","A substance that contains a biologically active compound is any substance which has as one of its components a biologically active compound .",".",".",".","Examples of substances containing biologically active compounds are, but not limited to, pharmaceutical formulations and products, cosmetic formulations and products, industrial formulations and products, agricultural formulations and products, foods, seeds, cocoa and cocoa solids, coffee, herbs, spices, other plant materials, minerals, animal products, shells and other skeletal material.","Any of the terms, “biological(ly) active”, “active”, “active material” shall have the same meaning as biologically active material.","The term “grinding matrix” is defined as any inert substance that a biologically active material can or is combined with and milled.","The terms “co-grinding matrix” and “matrix” are interchangeable with “grinding matrix”.","Particle Size There are a wide range of techniques that can be utilized to characterize the particle size of a material.","Those skilled in the art also understand that almost all these techniques do not physically measure the actually particle size, as one might measure something with a ruler, but measure a physical phenomena which is interpreted to indicate a particle size.","As part of the interpretation process some assumptions need to be made to enable mathematical calculations to be made.","These assumptions deliver results such as an equivalent spherical particle size, or a hydrodynamic radius.","Amongst these various methods, two types of measurements are most commonly used.","Photon correlation spectroscopy (PCS), also known as ‘dynamic light scattering’ (DLS) is commonly used to measure particles with a size less than 10 micron.","Typically this measurement yields an equivalent hydrodynamic radius often expressed as the average size of a number distribution.","The other common particle size measurement is laser diffraction which is commonly used to measure particle size from 100 nm to 2000 micron.","This technique calculates a volume distribution of equivalent spherical particles that can be expressed using descriptors such as the median particle size or the % of particles under a given size.","Those skilled in the art recognize that different characterization techniques such as photon correlation spectroscopy and laser diffraction measure different properties of a particle ensemble.","As a result multiple techniques will give multiple answers to the question, “what is the particle size.” In theory one could convert and compare the various parameters each technique measures, however, for real world particle systems this is not practical.","As a result the particle size used to describe this invention will be given as two different sets of values that each relate to these two common measurement techniques, such that measurements could be made with either technique and then evaluated against the description of this invention.","For measurements made using a photo correlation spectroscopy instrument, or an equivalent method known in the art, the term “number average particle size” is defined as the average particle diameter as determined on a number basis.","For measurements made using a laser diffraction instrument, or an equivalent method known in the art, the term “median particle size” is defined as the median particle diameter as determined on an equivalent spherical particle volume basis.","Where the term median is used, it is understood to describe the particle size that divides the population in half such that 50% of the population is greater than or less than this size.","The median particle size is often written as D50, D(0.50) or D[0.5] or similar.","As used herein D50, D(0.50) or D[0.5] or similar shall be taken to mean ‘median particle size’.","The term “Dx of the particle size distribution” refers to the xth percentile of the distribution; thus, D90 refers to the 90th percentile, D95 refers to the 95th percentile, and so forth.","Taking D90 as an example this can often be written as, D(0.90) or D[0.9] or similar.","With respect to the median particle size and Dx an upper case D or lowercase d are interchangeable and have the same meaning.","Another commonly used way of describing a particle size distribution measured by laser diffraction, or an equivalent method known in the art, is to describe what % of a distribution is under or over a nominated size.","The term “percentage less than” also written as “%<” is defined as the percentage, by volume, of a particle size distribution under a nominated size—for example the %<1000 nm.","The term “percentage greater than” also written as “%>” is defined as the percentage, by volume, of a particle size distribution over a nominated size—for example the %>1000 nm.","The particle size used to describe this invention should be taken to mean the particle size as measured at or shortly before the time of use.","For example, the particle size is measured 2 months after the material is subject to the milling method of this invention.","In a preferred form, the particle size is measured at a time selected from the group consisting of: 1 day after milling, 2 days after milling, 5 days after milling, 1 month after milling, 2 months after milling, 3 months after milling, 4 months after milling, 5 months after milling, 6 months after milling, 1 year after milling, 2 years after milling, 5 years after milling.","For many of the materials subject to the methods of this invention the particle size can be easily measured.","Where the active material has poor water solubility and the matrix it is milled in has good water solubility the powder can simply be dispersed in an aqueous solvent.","In this scenario the matrix dissolves leaving the active material dispersed in the solvent.","This suspension can then be measured by techniques such as PCS or laser diffraction.","Suitable methods to measure an accurate particle size where the active material has substantive aqueous solubility or the matrix has low solubility in a water based dispersant are outlined below.","1.In the circumstance where insoluble matrix such as microcrystalline cellulose prevents the measurement of the active material, separation techniques such as filtration or centrifugation could be used to separate the insoluble matrix from the active material particles.","Other ancillary techniques would also be required to determine if any active material was removed by the separation technique so that this could be taken into account.","2.In the case where the active material is too soluble in water other solvents could be evaluated for the measurement of particle size.","Where a solvent could be found that active material is poorly soluble in but is a good solvent for the matrix a measurement would be relatively straight forward.","If such a solvent is difficult to find another approach would be to measure the ensemble of matrix and active material in a solvent (such as iso-octane) which both are insoluble in.","Then the powder would be measured in another solvent where the active material is soluble but the matrix is not.","Thus with a measurement of the matrix particle size and a measurement of the size of the matrix and active material together an understanding of the active material particle size can be obtained.","3.In some circumstances image analysis could be used to obtain information about the particle size distribution of the active material.","Suitable image measurement techniques might include transmission electron microscopy (TEM), scanning electron microscopy (SEM), optical microscopy and confocal microscopy.","In addition to these standard techniques some additional technique would be required to be used in parallel to differentiate the active material and matrix particles.","Depending on the chemical makeup of the materials involved possible techniques could be elemental analysis, raman spectroscopy, FTIR spectroscopy or fluorescence spectroscopy.","Other Definitions Throughout this specification, unless the context requires otherwise, the phrase “dry mill” or variations, such as “dry milling”, should be understood to refer to milling in at least the substantial absence of liquids.","If liquids are present, they are present in such amounts that the contents of the mill retain the characteristics of a dry powder.","“Flowable” means a powder having physical characteristics rendering it suitable for further processing using typical equipment used for the manufacture of pharmaceutical compositions and formulations.","Other definitions for selected terms used herein may be found within the detailed description of the invention and apply throughout.","Unless otherwise defined, all other scientific and technical terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which the invention belongs.","The term “millable” means that the grinding matrix is capable of being physically degraded under the dry milling conditions of the method of the invention.","In one embodiment of the invention, the milled grinding matrix is of a comparable particle size to the biologically active material.","In another embodiment of the invention the particle size of the matrix is substantially reduced but not as small as the biologically active material Other definitions for selected terms used herein may be found within the detailed description of the invention and apply throughout.","Unless otherwise defined, all other scientific and technical terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which the invention belongs.","Specific In one embodiment, the present invention is directed to a method for improving the dissolution profile of a biologically active material, the method comprising the step of: dry milling a mixture of a solid biologically active material and a millable grinding matrix, in a mill comprising a plurality of milling bodies, to produce particles of a biologically active material dispersed in at least partially milled grinding matrix.","The mixture of active material and matrix may then be separated from the milling bodies and removed from the mill.","In one aspect the mixture of active material and matrix is then further processed.","In another aspect, the grinding matrix is separated from the particles of biologically active material.","In a further aspect, at least a portion of the milled grinding matrix is separated from the particulate biologically active material.","The milling bodies are essentially resistant to fracture and erosion in the dry milling process.","The quantity of the grinding matrix relative to the quantity of biologically active material in particulate form, and the extent of milling of the grinding matrix, is sufficient to improve the dissolution profile of the active material milled.","The present invention also relates to biologically active materials produced by said methods, to medicaments produced using said biologically active materials and to methods of treatment of an animal, including man, using a therapeutically effective amount of said biologically active materials administered by way of said medicaments.","Improving the Dissolution Profile The present invention leads to the improved dissolution profile.","An improved dissolution profile has significant advantages including the improvement of bioavailability of the biologically active material in vivo.","Preferably, the improved dissolution profile is observed in vitro.","Alternatively, the improved dissolution profile is observed in vivo by the observation of an improved bioavailability profile.","Standard methods for determining the dissolution profile of a material in vitro are available in the art.","A suitable method to determine an improved dissolution profile in vitro may include determining the concentration of the sample material in a solution over a period of time and comparing the results from the sample material to a control sample.","An observation that peak solution concentration for the sample material was achieved in less time than the control sample would indicate (assuming it is statistically significant), that the sample material has an improved dissolution profile.","The measurement sample is herein defined as the mixture of biologically active material with grinding matrix and/or other additives that has been subject to the processes of the invention described here.","Herein a control sample is defined as a physical mixture (not subject to the processes described in this invention) of the components in the measurement sample with the same relative proportions of active, matrix and/or additive as the measurement sample.","For the purposes of the dissolution testing a prototype formulation of the measurement sample could also be used.","In this case the control sample would be formulated in the same way.","Standard methods for determining the improved dissolution profile of a material in vivo are available in the art.","A suitable method to determine an improved dissolution profile in a human may be after delivering the dose to measure the rate of active material absorption by measuring the plasma concentration of the sample compound over a period of time and comparing the results from the sample compound to a control.","An observation that peak plasma concentration for the sample compound was achieved in less time than the control would indicate (assuming it is statistically significant) that the sample compound has improved bioavailability and an improved dissolution profile.","Preferably, the improved dissolution profile is observed at a relevant gastrointestinal pH, when it is observed in vitro.","Preferably, the improved dissolution profile is observed at a pH which is favourable at indicating improvements in dissolution when comparing the measurement sample to the control compound.","Suitable methods for quantifying the concentration of a compound in an in vitro sample or an in vivo sample are widely available in the art.","Suitable methods could include the use of spectroscopy or radioisotope labeling.","In one preferred embodiment the method of quantification of dissolution is determined in a solution with a pH selected from the group consisting of: pH 1, pH 2, pH 3, pH 4, pH 5, pH 6, pH 7, pH 7.3, pH 7.4, pH 8, pH 9, pH 10, pH 11, pH 12, pH 13, pH 14 or a pH with 0.5 of a pH unit of any of this group.","Crystallization Profile Methods for determining the crystallinity profile of the biologically active material are widely available in the art.","Suitable methods may include X-ray diffraction, differential scanning calorimetry, raman or IR spectroscopy.","Amorphicity Profile Methods for determining the amorphous content of the biologically active material are widely available in the art.","Suitable methods may include X-ray diffraction, differential scanning calorimetry, raman or IR spectroscopy.","Grinding Matrix As will be described subsequently, selection of an appropriate grinding matrix affords particular advantageous applications of the method of the present invention.","A highly advantageous application of the method of the invention is the use of a water-soluble grinding matrix in conjunction with a poorly water-soluble biologically active material.","This affords at least two advantages.","The first being when the powder containing the biologically active material is placed into water—such as the ingestion of the powder as part of an oral medication—the matrix dissolves, releasing the particulate active material such that there is maximum surface area exposed to solution, thereby allowing a rapid dissolution of the active compound.","The second key advantage is the ability, if required, to remove or partially remove the matrix prior to further processing or formulation.","Another advantageous application of the method of the invention is the use of a water-insoluble grinding matrix, particularly in the area of agricultural use, when a biologically active material such as a fungicide is commonly delivered as part of a dry powder or a suspension.","The presence of a water insoluble matrix will afford benefits such as increased rain fastness.","Without wishing to be bound by theory, it is believed that the physical degradation (including but not limited to particle size reduction) of the millable grinding matrix affords the advantage of the invention, by acting as a more effective diluent than grinding matrix of a larger particle size.","Again, as will be described subsequently, a highly advantageous aspect of the present invention is that certain grinding matrixes appropriate for use in the method of the invention are also appropriate for use in a medicament.","The present invention encompasses methods for the production of a medicament incorporating both the biologically active material and the grinding matrix or in some cases the biologically active material and a portion of the grinding matrix, medicaments so produced, and methods of treatment of an animal, including man, using a therapeutically effective amount of said biologically active materials by way of said medicaments.","Analogously, as will be described subsequently, a highly advantageous aspect of the present invention is that certain grinding matrixes appropriate for use in the method of the invention are also appropriate for use in a carrier for an agricultural chemical, such as a pesticide, fungicide, or herbicide.","The present invention encompasses methods for the production of an agricultural chemical composition incorporating both the biologically active material in particulate form and the grinding matrix, or in some cases the biologically active material, and a portion of the grinding matrix, and agricultural chemical compositions so produced.","The medicament may include only the biologically active material together with the milled grinding matrix or, more preferably, the biologically active material and milled grinding matrix may be combined with one or more pharmaceutically acceptable carriers, as well as any desired excipients or other like agents commonly used in the preparation of medicaments.","Analogously, the agricultural chemical composition may include only the biologically active material together with the milled grinding matrix or, more preferably, the biologically active materials and milled grinding matrix may be combined with one or more carriers, as well as any desired excipients or other like agents commonly used in the preparation of agricultural chemical compositions.","In one particular form of the invention, the grinding matrix is both appropriate for use in a medicament and readily separable from the biologically active material by methods not dependent on particle size.","Such grinding matrixes are described in the following detailed description of the invention.","Such grinding matrixes are highly advantageous in that they afford significant flexibility in the extent to which the grinding matrix may be incorporated with the biologically active material into a medicament.","In a highly preferred form, the grinding matrix is harder than the biologically active material, and is thus capable of improving the dissolution profile of the active material under the dry milling conditions of the invention.","Again without wishing to be bound by theory, under these circumstances it is believed that the millable grinding matrix affords the advantage of the present invention through a second route, with the smaller particles of grinding matrix produced under the dry milling conditions enabling greater interaction with the biologically active material.","The quantity of the grinding matrix relative to the quantity of biologically active material, and the extent of physical degradation of the grinding matrix, is sufficient to improve the dissolution profile of the milled biologically active material.","The grinding matrix is not generally selected to be chemically reactive with the biologically active material under the milling conditions of the invention, excepting for example, where the matrix is deliberately chosen to undergo a mechanico-chemical reaction.","Such a reaction might be the conversion of a free base or acid to a salt or vice versa.","As stated above, the method of the present invention requires the grinding matrix to be milled with the biologically active material; that is, the grinding matrix will physically degrade under the dry milling conditions of the invention to facilitate the formation and retention of particulates of the biologically active material with improved dissolution profiles.","The precise extent of degradation required will depend on certain properties of the grinding matrix and the biologically active material, the ratio of biologically active material to grinding matrix, and the particle size distribution of the particles comprising the biologically active material.","The physical properties of the grinding matrix necessary to achieve the requisite degradation are dependent on the precise milling conditions.","For example, a harder grinding matrix may degrade to a sufficient extent provided [it is subjected to] more vigorous dry milling conditions.","Physical properties of the grinding matrix relevant to the extent that the agent will degrade under dry milling conditions include hardness, friability, as measured by indicia such as hardness, fracture toughness and brittleness index.","A low hardness (typically a Mohs Hardness less than 7) of the biologically active material is desirable to ensure fracture of the particles during processing, so that composite microstructures develop during milling.","Preferably, the hardness is less than 3 as determined using the Mohs Hardness scale.","Preferably, the grinding matrix is of low abrasivity.","Low abrasivity is desirable to minimise contamination of the mixture of the biologically active material in the grinding matrix by the milling bodies and/or the milling chamber of the media mill.","An indirect indication of the abrasivity can be obtained by measuring the level of milling-based contaminants.","Preferably, the grinding matrix has a low tendency to agglomerate during dry milling.","While it is difficult to objectively quantify the tendency to agglomerate during milling, it is possible to obtain a subjective measure by observing the level of “caking” of the grinding matrix on the milling bodies and the milling chamber of the media mill as dry milling progresses.","The grinding matrix may be an inorganic or organic substance.","In one embodiment, the grinding matrix is selected from the following, either as a single substance or a combination of

w/w, 0.1-5% w/w, 0.1-2.5% w/w, of 0.1-2% w/w, 0.1-1%, 0.5-5% w/w, 0.5-3% w/w, 0.5-2% w/w, 0.5-1.5%, 0.5-1% w/w, of 0.75-1.25% w/w, 0.75-1% and 1% w/w.","Milling Bodies In the method of the present invention, the milling bodies are preferably chemically inert and rigid.","The term “chemically-inert”, as used herein, means that the milling bodies do not react chemically with the biologically active material or the grinding matrix.","As described above, the milling bodies are essentially resistant to fracture and erosion in the milling process.","The milling bodies are desirably provided in the form of bodies which may have any of a variety of smooth, regular shapes, flat or curved surfaces, and lacking sharp or raised edges.","For example, suitable milling bodies can be in the form of bodies having ellipsoidal, ovoid, spherical or right cylindrical shapes.","Preferably, the milling bodies are provided in the form of one or more of beads, balls, spheres, rods, right cylinders, drums or radius-end right cylinders (i.e., right cylinders having hemispherical bases with the same radius as the cylinder).","Depending on the nature of the biologically active material and the grinding matrix, the milling media bodies desirably have an effective mean particle diameter (i.e.","“particle size”) between about 0.1 and 30 mm, more preferably between about 1 and about 15 mm, still more preferably between about 3 and 10 mm.","The milling bodies may comprise various substances such as ceramic, glass, metal or polymeric compositions, in a particulate form.","Suitable metal milling bodies are typically spherical and generally have good hardness (i.e.","RHC 60-70), roundness, high wear resistance, and narrow size distribution and can include, for example, balls fabricated from type 52100 chrome steel, type 316 or 440C stainless steel or type 1065 high carbon steel.","Preferred ceramics, for example, can be selected from a wide array of ceramics desirably having sufficient hardness and resistance to fracture to enable them to avoid being chipped or crushed during milling and also having sufficiently high density.","Suitable densities for milling media can range from about 1 to 15 g/cm3′, preferably from about 1 to 8 g/cm3.Preferred ceramics can be selected from steatite, aluminum oxide, zirconium oxide, zirconia-silica, yttria-stabilized zirconium oxide, magnesia-stabilized zirconium oxide, silicon nitride, silicon carbide, cobalt-stabilized tungsten carbide, and the like, as well as mixtures thereof.","Preferred glass milling media are spherical (e.g.","beads), have a narrow size distribution, are durable, and include, for example, lead-free soda lime glass and borosilicate glass.","Polymeric milling media are preferably substantially spherical and can be selected from a wide array of polymeric resins having sufficient hardness and friability to enable them to avoid being chipped or crushed during milling, abrasion-resistance to minimize attrition resulting in contamination of the product, and freedom from impurities such as metals, solvents, and residual monomers.","Preferred polymeric resins, for example, can be selected from crosslinked polystyrenes, such as polystyrene crosslinked with divinylbenzene, styrene copolymers, polyacrylates such as polymethylmethacrylate, polycarbonates, polyacetals, vinyl chloride polymers and copolymers, polyurethanes, polyamides, high density polyethylenes, polypropylenes, and the like.","The use of polymeric milling media to grind materials down to a very small particle size (as opposed to mechanochemical synthesis) is disclosed, for example, in U.S. Pat.","Nos.","5,478,705 and 5,500,331.Polymeric resins typically have densities ranging from about 0.8 to 3.0 g/cm3.Higher density polymeric resins are preferred.","Alternatively, the milling media can be composite particles comprising dense core particles having a polymeric resin adhered thereon.","Core particles can be selected from substances known to be useful as milling media, for example, glass, alumina, zirconia silica, zirconium oxide, stainless steel, and the like.","Preferred core substances have densities greater than about 2.5 g/cm3.In one embodiment of the invention, the milling media are formed from a ferromagnetic substance, thereby facilitating removal of contaminants arising from wear of the milling media by the use of magnetic separation techniques.","Each type of milling body has its own advantages.","For example, metals have the highest specific gravities, which increase grinding efficiency due to increased impact energy.","Metal costs range from low to high, but metal contamination of final product can be an issue.","Glasses are advantageous from the standpoint of low cost and the availability of small bead sizes as low as 0.004 mm.","However, the specific gravity of glasses is lower than other media and significantly more milling time is required.","Finally, ceramics are advantageous from the standpoint of low wear and contamination, ease of cleaning, and high hardness.","Dry Milling In the dry milling process of the present invention, the biologically active material and grinding matrix, in the form of crystals, powders, or the like, are combined in suitable proportions with the plurality of milling bodies in a milling chamber that is mechanically agitated (i.e.","with or without stirring) for a predetermined period of time at a predetermined intensity of agitation.","Typically, a milling apparatus is used to impart motion to the milling bodies by the external application of agitation, whereby various translational, rotational or inversion motions or combinations thereof are applied to the milling chamber and its contents, or by the internal application of agitation through a rotating shaft terminating in a blade, propeller, impeller or paddle or by a combination of both actions.","During milling, motion imparted to the milling bodies can result in application of shearing forces as well as multiple impacts or collisions having significant intensity between milling bodies and particles of the biologically active material and grinding matrix.","The nature and intensity of the forces applied by the milling bodies to the biologically active material and the grinding matrix is influenced by a wide variety of processing parameters including: the type of milling apparatus; the intensity of the forces generated, the kinematic aspects of the process; the size, density, shape, and composition of the milling bodies; the weight ratio of the biologically active material and grinding matrix mixture to the milling bodies; the duration of milling; the physical properties of both the biologically active material and the grinding matrix; the atmosphere present during activation; and others.","Advantageously, the media mill is capable of repeatedly or continuously applying mechanical compressive forces and shear stress to the biologically active material and the grinding matrix.","Suitable media mills include but are not limited to the following: high-energy ball, sand, bead or pearl mills, basket mill, planetary mill, vibratory action ball mill, multi-axial shaker/mixer, stirred ball mill, horizontal small media mill, multi-ring pulverizing mill, and the like, including small milling media.","The milling apparatus also can contain one or more rotating shafts.","In a preferred form of the invention, the dry milling is performed in a ball mill.","Throughout the remainder of the specification reference will be made to dry milling being carried out by way of a ball mill.","Examples of this type of mill are attritor mills, nutating mills, tower mills, planetary mills, vibratory mills and gravity-dependent-type ball mills.","It will be appreciated that dry milling in accordance with the method of the invention may also be achieved by any suitable means other than ball milling.","For example, dry milling may also be achieved using jet mills, rod mills, roller mills or crusher mills.","Biologically Active Material The biologically active material includes active

may be employed on formulations or agents that already have reduced particle size compared to their conventional form.","Biologically active materials suitable for use in the invention include actives, biologics, amino acids, proteins, peptides, nucleotides, nucleic acids, and analogs, homologs and first order derivatives thereof.","The biologically active material can be selected from a

incorporated by reference.","Another source of active agents is the Physicians Desk Reference (60th Ed., pub.","2005), familiar to those of skill in the art.","The active agents are commercially available and/or can be prepared by techniques known in the art.","An exhaustive list of drugs for which the methods of the invention are suitable would be burdensomely long for this specification; however, reference to the general pharmacopoeia listed above would allow one of skill in the art to select virtually any drug to which the method of the invention may be applied.","In addition it is also expected that new chemical entities (NCE) and other actives for which the methods of the invention are suitable will be created or become commercially available in the future.","Notwithstanding the general applicability of the method of the invention, more specific examples of biologically active materials include, but are not limited to: haloperidol (dopamine antagonist), DL isoproterenol

base.","Specifically the chemical makeup and the functional groups, including an acid or base group, are generally not the determinant factor, excepting a possible chemical reaction with a specific matrix, for the successful creation of a biologically active substance with improved dissolution.","This invention is not limited to any drug specific class, application type, chemical type or function grouping.","Rather the suitability of a biologically active material for use in this invention is primarily determined by the mechanical properties of the material.","In addition, some biologically active materials may have the benefit of absorption through the skin if presented in a particle formulation.","Such biologically active materials include, but are not limited to, Voltaren (diclofenac), rofecoxib, and ibuprofen.","Conveniently, the biologically active material is capable of withstanding temperatures that are typical in uncooled dry milling, which may exceed 80° C. Therefore, materials with a melting point about 80° C. or greater are highly suitable.","For biologically active materials with lower melting points, the media mill may be cooled, thereby allowing materials with significantly lower melting temperatures to be processed according to the method of the invention.","For instance, a simple water-cooled mill will keep temperatures below 50° C., or chilled water could be used to further lower the milling temperature.","Those skilled in the art will understand that a high energy ball mill could be designed to run at any temperature between say −30 to 200° C. For some biologically active materials it may be advantageous to control the milling temperature to temperatures significantly below the melting points of the biologically active materials.","The biologically active material is obtained in a conventional form commercially and/or prepared by techniques known in the art.","It is preferred, but not essential, that the particle size of the biologically active material be less than about 1000 μm, as determined by sieve analysis.","If the coarse particle size of the biologically active material is greater than about 1000 μm, then it is

Preferably, the biologically active materials, which have been subject to the methods of the invention, comprises particles of biologically active material of an average particle size diameter equal or greater than 1 μm, determined on a particle number basis.","Preferably, the biologically active materials, which have been subject to the methods of the invention, comprises particles of

be understood to fall within the scope of the present invention if at the time of use, or further processing, the particle size of the agglomerate is within the ranges specified above.","Processing Time Preferably, the biologically active material and the grinding matrix are dry milled for the shortest time necessary to form the mixture of the biologically active material in the grinding matrix such that the active material has improved dissolution to minimise any possible contamination from the media mill and/or the plurality of milling bodies.","This time varies greatly, depending on the biologically active material and the grinding matrix, and may range from as short as 1 minute to several hours.","Dry milling times in excess of 2 hours may lead to degradation of the biologically active material and an increased level of undesirable contaminants.","Suitable rates of agitation and total milling times are adjusted for the type and size of milling apparatus as well as the milling media, the weight ratio of the biologically active material and grinding matrix mixture to the plurality of milling bodies, the chemical and physical properties of the biologically active material and grinding matrix, and other parameters that may be optimized empirically.","Inclusion of the Grinding Matrix with the Biologically Active Material and Separation of the Grinding Matrix from the Biologically Active Material In a preferred aspect, the grinding matrix is not separated from the biologically active material but is maintained with the biologically active material in the final product.","Preferably the grinding matrix is considered to be Generally Regarded as Safe (GRAS) for pharmaceutical products.","In an alternative aspect, the grinding matrix is separated from the biologically active material.","In one aspect, where the grinding matrix is not fully milled, the unmilled grinding matrix is separated from the biologically active material.","In a further aspect, at least a portion of the milled grinding matrix is separated from the biologically active material.","Any portion of the grinding matrix may be removed, including but not limited to 10%, 25%, 50%, 75%, or substantially all of the grinding matrix.","In some embodiments of the invention, a significant portion of the milled grinding matrix may comprise particles of a size similar to and/or smaller than the particles comprising the biologically active material.","Where the portion of the milled grinding matrix to be separated from the particles comprising the biologically active material comprises particles of a size similar to and/or smaller than the particles comprising the biologically active material, separation techniques based on size distribution are inapplicable.","In these circumstances, the method of the present invention may involve separation of at least a portion of the milled grinding matrix from the biologically active material by techniques including but not limited to electrostatic separation, magnetic separation, centrifugation (density separation), hydrodynamic separation, froth flotation.","Advantageously, the step of removing at least a portion of the milled grinding matrix from the biologically active material may be performed through means such as selective dissolution, washing, or sublimation.","An advantageous aspect of the invention would be the use of grinding matrix that has two or more components where at least one component is water soluble and at least one component has low solubility in water.","In this case washing can be used to remove the matrix component soluble in water leaving the biologically active material encapsulated in the remaining matrix components.","In a highly advantageous aspect of the invention the matrix with low solubility is a functional excipient.","A highly advantageous aspect of the present invention is that certain grinding matrixes appropriate for use in the method of the invention (in that they physically degrade to the desired extent under dry milling conditions) are also pharmaceutically acceptable and thus appropriate for use in a medicament.","Where the method of the present invention does not involve complete separation of the grinding matrix from the biologically active material, the present invention encompasses methods for the production of a medicament incorporating both the biologically active material and at least a portion of the milled grinding matrix, medicaments so produced and methods of treatment of an animal, including man, using a therapeutically effective amount of said biologically active materials by way of said medicaments.","The medicament may include only the biologically active material and the grinding matrix or, more preferably, the biologically active materials and grinding matrix may be combined with one or more pharmaceutically acceptable carriers, as well as any desired excipients or other like agents commonly used in the preparation of medicaments.","Analogously, a highly advantageous aspect of the present invention is that certain grinding matrixes appropriate for use in the method of the invention (in that they physically degrade to a desirable extent under dry milling conditions) are also appropriate for use in an agricultural chemical composition.","Where the method of the present invention does not involve complete separation of the grinding matrix from the biologically active material, the present invention encompasses methods for the production of a agricultural chemical composition incorporating both the biologically active material and at least a portion of the milled grinding matrix, agricultural chemical composition so produced and methods of use of such compositions.","The agricultural chemical composition may include only the biologically active material and the grinding matrix or, more preferably, the biologically active materials and grinding matrix may be combined with one or more acceptable carriers, as well as any desired excipients or other like agents commonly used in the preparation of agricultural chemical compositions.","In one particular form of the invention, the grinding matrix is both appropriate for use in a medicament and readily separable from the biologically active material by methods not dependent on particle size.","Such grinding matrixes are described in the following detailed description of the invention.","Such grinding matrixes are highly advantageous in that they afford significant flexibility in the extent to which the grinding matrix may be incorporated with the biologically active material into a medicament.","The mixture of biologically active material and grinding matrix may then be separated from the milling bodies and removed from the mill.","In one embodiment, the grinding matrix is separated from the mixture of biologically active material and grinding matrix.","Where the grinding matrix is not fully milled, the unmilled grinding matrix is separated from the biologically active material.","In a further aspect, at least a portion of the milled grinding matrix is separated from the biologically active material.","The milling bodies are essentially resistant to fracture and erosion in the dry milling process.","The quantity of the grinding matrix relative to the quantity of biologically active material, and the extent of milling of the grinding matrix, is sufficient to provide improved dissolution of the biologically active material.","The grinding matrix is neither chemically nor mechanically reactive with the pharmaceutical material under the dry milling conditions of the method of the invention except, for example, where the matrix is deliberately chosen to undergo a mechanico-chemical reaction.","Such a reaction might be the conversion of a free base or acid to a salt or vice versa.","Preferably, the medicament is a solid dosage form, however, other dosage forms may be prepared by those of ordinary skill in the art.","In one form, after the step of separating said mixture of biologically active material and grinding matrix from the plurality of milling bodies, and before the step of using said mixture of biologically active material and grinding matrix in the manufacture of a medicament, the method may comprise the step of: removing a portion of the grinding matrix from said mixture of biologically active material and grinding matrix to provide a mixture enriched in the biologically active material; and the step of using said mixture of biologically active material and grinding matrix in the manufacture of a medicament, more particularly comprises the step of using the mixture of biologically active material and grinding matrix enriched in the biologically active material form in the manufacture of a medicament.","The present invention includes medicaments manufactured by said methods, and methods for the treatment of an animal, including man, by the administration of a therapeutically effective amount of the biologically active materials by way of said medicaments.","In another embodiment of the invention, a facilitating agent or a combination of facilitating agents is also comprised in the mixture to be milled.","Such facilitating agents appropriate for use in the invention include diluents, surfactants, polymers, binding agents, filling agents, lubricating agents, sweeteners, flavouring agents, preservatives, buffers, wetting agents, disintegrants, effervescent agents and agents that may form part of a medicament, including a solid dosage form, or other excipients required for other specific drug delivery, such as the agents and media listed below under the heading Medicinal and Pharmaceutical Compositions, or any combination thereof.","Biologically Active Materials and Compositions The present invention encompasses pharmaceutically acceptable materials produced according to the methods of the present invention, compositions including such materials, including compositions comprising such materials together with the grinding matrix, with at least a portion of the grinding matrix or separated from the grinding matrix.","The pharmaceutically acceptable materials within the compositions of the invention are present at a concentration of between about 0.1% and about 99.0% by weight.","Preferably, the concentration of pharmaceutically acceptable materials within the compositions will be about 5% to about 80% by weight, while concentrations of 10% to about 50% by weight are highly preferred.","Desirably, the concentration will be in the range of about 10 to 15% by weight, 15 to 20% by weight, 20 to 25% by weight, 25 to 30% by weight, 30 to 35% by weight, 35 to 40% by weight, 40 to 45% by weight, 45 to 50% by weight, 50 to 55% by weight, 55 to 60% by weight, 60 to 65% by weight, 65 to 70% by weight, 70 to 75% by weight or 75 to 80% by weight for the composition prior to any later removal (if desired) of any portion of the grinding matrix.","Where part or all of the grinding matrix has been removed, the relative concentration of pharmaceutically acceptable materials in the composition may be considerably higher depending on the amount of the grinding matrix that is removed.","For example, if all of the grinding matrix is removed the concentration of particles in the preparation may approach 100% by weight (subject to the presence of facilitating agents).","Compositions produced according to the present invention are not limited to the inclusion of a single species of pharmaceutically acceptable materials.","More than one species of pharmaceutically acceptable materials may therefore be present in the composition.","Where more than one species of pharmaceutically acceptable materials is present, the composition so formed may either be prepared in a dry milling step, or the pharmaceutically acceptable materials may be prepared separately and then combined to form a single composition.","Medicaments The medicaments of the present invention may include the pharmaceutically acceptable material, optionally together with the grinding matrix or at least a portion of the grinding matrix, combined with one or more pharmaceutically acceptable carriers, as well as other agents commonly used in the preparation of

extemporaneous preparation of sterile injectable solutions or dispersion.","The use of such media and agents for the manufacture of medicaments is well known in the art.","Except insofar as any conventional media or agent is incompatible with the pharmaceutically acceptable material, use thereof in the manufacture of a pharmaceutical composition according to the invention is contemplated.","Pharmaceutical acceptable carriers according to the invention may include one or more of the following examples: (1) surfactants and polymers, including, but not limited to

animals and in particular in man typically must be sterile and stable under the conditions of manufacture and storage.","The medicaments of the invention comprising the biologically active material can be formulated as a solid, a solution, a microemulsion, a liposome, or other ordered structures suitable to high drug concentration.","Actual dosage levels of the biologically active material in the medicament of the invention may be varied in accordance with the nature of the biologically active material, as well as the potential increased efficacy due to the advantages of providing and administering the biologically active material (e.g., increased solubility, more rapid dissolution, increased surface area of the biologically active material, etc.).","Thus as used herein “therapeutically effective amount” will refer to an amount of biologically active material required to effect a therapeutic response in an animal.","Amounts effective for such a use will depend on: the desired therapeutic effect; the route of administration; the potency of the biologically active material; the desired duration of treatment; the stage and severity of the disease being treated; the weight and general state of health of the patient; and the judgment of the prescribing physician.","In another embodiment, the biologically active material, optionally together with the grinding matrix or at least a portion of the grinding matrix, of the invention may be combined into a medicament with another biologically active material, or even the same biologically active material.","In the latter embodiment, a medicament may be achieved which provides for different release characteristics—early release from the biologically active material, and later release from a larger average size biologically active material.","Modes of Administration of Medicaments Comprising Biologically Active Materials Medicaments of the invention can be administered to animals, including man, in any pharmaceutically acceptable manner, such as orally, rectally, pulmonary, intravaginally, locally (powders, ointments or drops), transdermal, parenteral administration, intravenous, intraperitoneal, intramuscular, sublingual or as a buccal or nasal spray Solid dosage forms for oral administration include capsules, tablets, pills, powders, pellets, and granules.","Further, incorporating any of the normally employed excipients, such as those previously listed, and generally 5-95% of the biologically active agent, and more preferably at a concentration of 10%-75% will form a pharmaceutically acceptable non-toxic oral composition.","Medicaments of the invention may be parenterally administered as a solution of the biologically active agent suspended in an acceptable carrier, preferably an aqueous carrier.","A variety of aqueous carriers may be used, e.g.","water, buffered water, 0.4% saline, 0.3% glycine, hyaluronic acid and the like.","These compositions may be sterilized by conventional, well known sterilization techniques, or may be sterile filtered.","The resulting aqueous solutions may be packaged for use as is, or lyophilized, the lyophilized preparation being combined with a sterile solution prior to administration.","For aerosol administration, medicaments of the invention are preferably supplied along with a surfactant or polymer and propellant.","The surfactant or polymer must, of course, be non-toxic, and preferably soluble in the propellant.","Representative of such agents are the esters or partial esters of fatty acids containing from 6 to 22 carbon atoms, such as caproic, octanoic, lauric, palmitic, stearic, linoleic, linolenic, olesteric and oleic acids with an aliphatic polyhydric alcohol or its cyclic anhydride.","Mixed esters, such as mixed or natural glycerides may be employed.","The surfactant or polymer may constitute 0.1%-20% by weight of the composition, preferably 0.25-5%.","The balance of the composition is ordinarily propellant.","A carrier can also be included, as desired, as with, e.g., lecithin for intranasal delivery.","Medicaments of the invention may also be administered via liposomes, which serve to target the active agent to a particular tissue, such as lymphoid tissue, or targeted selectively to cells.","Liposomes include emulsions, foams, micelles, insoluble monolayers, liquid crystals, phospholipid dispersions, lamellar layers and the like.","In these preparations the composite microstructure composition is incorporated as part of a liposome, alone or in conjunction with a molecule that binds to or with other therapeutic or immunogenic compositions.","As described above, the biologically active material can be formulated into a solid dosage form (e.g., for oral or suppository administration), together with the grinding matrix or at least a portion of it.","In this case there may be little or no need to add stabilizing agents since the grinding matrix may effectively act as a solid-state stabilizer.","However, if the biologically active material is to be utilized in a liquid suspension, the particles comprising the biologically active material may require further stabilization once the solid carrier has been substantially removed to ensure the elimination, or at least minimisation of particle agglomeration.","Therapeutic Uses Therapeutic uses of the medicaments of the invention include pain relief, anti-inflammatory, migraine, asthma, and other disorders that require the active agent to be administered with a high bioavailability.","One of the main areas when rapid bioavailability of a biologically active material is required is in the relief of pain.","The minor analgesics, such as cyclooxgenase inhibitors (aspirin related drugs) may be prepared as medicaments according to the present invention.","Medicaments of the invention may also be used for treatment of eye disorders.","That is, the biologically active material may be formulated for administration on the eye as an aqueous suspension in physiological saline, or a gel.","In addition, the biologically active material may be prepared in a powder form for administration via the nose for rapid central nervous system penetration.","Treatment of cardiovascular disease may also benefit from biologically active materials according to the invention, such as treatment of angina pectoris and, in particular, molsidomine may benefit from better bioavailability.","Other therapeutic uses of the medicaments of the present invention include treatment of hair loss, sexual dysfunction, or dermal treatment of psoriasis.","The present invention will now be described with reference to the following non-limiting Examples.","The description of the Examples is in no way limiting on the preceding paragraphs of this specification, but is provided for exemplification of the methods and compositions of the invention.","EXAMPLES It will be apparent to persons skilled in the milling and pharmaceutical arts that numerous enhancements and modifications can be made to the above described processes without departing from the basic inventive concepts.","For example, in some applications the biologically active material may be pretreated and supplied to the process in the pretreated form.","All such modifications and enhancements are considered to be within the scope of the present invention, the nature of which is to be determined from the foregoing description and the appended claims.","Furthermore, the following Examples are provided for illustrative purposes only, and are

milled materials as well as unmilled controls were determined using an automated Varian 7025 dissolution unit fitted with a Cary 50 Tablet UV visible spectrometer.","Dissolution settings used were

gelatine capsules contained 20 mg Diclofenac, for example, a capsule prepared from a 10 wt % Diclofenac milling required 200 mg milled powder.","Capsules of milled materials were filled using Profill® equipment.","Un-milled control samples were prepared by hand-filling appropriately sized capsules.","Each dissolution result was obtained by averaging results from 3 capsules.","Quantitative results are given as the time to reach X and Y. X is defined as the concentration equal to the dissolution concentration achieved by a control sample (or prototype formulation thereof) of the biologically active material or compound after 60 minutes.","Y is defined as the concentration equal to the dissolution concentration achieved by a control sample (or prototype formulation thereof) of the biologically active material or compound after 30 minutes.","Powder X-Ray diffraction (XRD) patterns were measured with a Diffractometer D 5000, Kristalloflex (Siemens).","The measurement range was from 5-18 degrees 2-Theta.","The slit width was set to 2 mm and the cathode ray tube was operated at 40 kV and 35 mA.","Measurements were recorded at room temperature.","The recorded traces were subsequently processed using Bruker EVA software

compositions, particularly those materials containing a biologically active material that is poorly soluble in water at physiological pH.\",\n \"An active material's bioavailability is the degree to which the active material becomes available to the target tissue in the body after systemic administration through, for example, oral or intravenous means.\",\n \"Many factors affect bioavailability, including the form of dosage and the solubility and dissolution rate of the active material.\",\n \"Poorly and slowly water-soluble materials tend to be eliminated from the gastrointestinal tract before being absorbed into the circulation.\",\n \"In addition, poorly soluble active agents tend to be disfavored or even unsafe for intravenous administration due to the risk of particles of agent blocking blood flow through capillaries.\",\n \"It is known that the rate of dissolution of a particulate drug will increase with increasing surface area.\",\n \"One way of increasing surface area is decreasing particle size.\",\n \"Consequently, methods of making finely divided or sized drugs have been studied with a view to controlling the size and size range of drug particles for pharmaceutical compositions.\",\n \"For example, dry milling techniques have been used to reduce particle size and hence influence drug absorption.\",\n \"However, in conventional dry milling the limit of fineness is reached generally in the region of about 100 microns (100,000 nm), at which point material cakes on the milling chamber and prevents any further diminution of particle size.\",\n \"Alternatively, wet grinding may be employed to reduce particle size, but flocculation restricts the lower particle size limit to approximately 10 microns (10,000 nm).\",\n \"The wet milling process, however, is prone to contamination, thereby leading to a bias in the pharmaceutical art against wet milling.\",\n \"Another alternative milling technique, commercial airjet milling, has provided particles ranging in average size from as low as about 1 to about 50 microns (1,000-50,000 nm).\",\n \"There are several approaches currently used to formulate poorly soluble active agents.\",\n \"One approach is to prepare the active agent as a soluble salt.\",\n \"Where this approach cannot be employed, alternate (usually physical) approaches are employed to improve the solubility of the active agent.\",\n \"Alternate approaches generally subject the active agent to physical conditions that change the agent's physical and or chemical properties to improve its solubility.\",\n \"These include process technologies such as micronization, modification of crystal or polymorphic structure, development of oil based solutions, use of co-solvents, surface stabilizers or complexing agents, micro-emulsions, super critical fluid and production of solid dispersions or solutions.\",\n \"More than one of these processes may be used in combination to improve formulation of a particular therapeutic material.\",\n \"Many of these approaches commonly convert a drug into an amorphous state, which generally leads to a higher dissolution rate.\",\n \"However, formulation approaches that result in the production of amorphous material are not common in commercial formulations due to concerns relating to stability and the potential for material to re-crystallize.\",\n \"These techniques for preparing such pharmaceutical compositions tend to be complex.\",\n \"By way of example, a principal technical difficulty encountered with emulsion polymerization is the removal of contaminants, such as unreacted monomers or initiators (which may have undesirable levels of toxicity), at the end of the manufacturing process.\",\n \"Another method of providing reduced particle size is the formation of pharmaceutical drug microcapsules, which techniques include micronizing, polymerisation and co-dispersion.\",\n \"However, these techniques suffer from a number of disadvantages including at least the inability to produce sufficiently small particles such as those obtained by milling, and the presence of co-solvents and/or contaminants such as toxic monomers which are difficult to remove, leading to expensive manufacturing processes.\",\n \"Over the last decade, intense scientific investigation has been carried out to improve the solubility of active agents by converting the agents to ultra fine powders by methods such as milling and grinding.\",\n \"These techniques may be used to increase the dissolution rate of a particulate solid by increasing the overall surface area and decreasing the mean particle size.\",\n \"U.S. Pat.\",\n \"No.\",\n \"6,634,576 discloses examples of wet-milling a solid substrate, such as a pharmaceutically active compound, to produce a “synergetic

such as meloxicam (marketed as Mobic® by pharmaceutical company Boehringer Ingelheim) provides pain relief for chronic pain, but must be taken on a daily basis to maintain an effective therapeutic level.\",\n \"Meloxicam is a poorly water soluble drug which is only slowly absorbed by the body (Tmax is 4-5 hours), so a method such as the present invention which provides for improved dissolution, will likely provide much faster absorption resulting in a more rapid onset of the therapeutic effect.\",\n \"Meloxicam also has a long half life (15-20 hours) that means it only need be taken once a

\"If the low solubility does contribute to this sub optimal bioavailability, the improvement of the dissolution of this drug with a method such as the present invention could provide scope to produce a dosage form with a lower active dose whilst still providing the effective therapeutic dose.\",\n \"Although the background to the present invention is discussed in the context of improving the

relates to methods for improving the dissolution profile of a biologically active material.\",\n \"The invention also relates to biologically active materials in particulate form produced by said methods, compositions comprising such materials, medicaments produced using said biologically active materials in particulate form and/or compositions, and to methods of treatment of an animal, including man, using a therapeutically effective amount of said biologically active materials administered by way of said medicaments.\",\n \"BACKGROUND Poor bioavailability is a significant problem encountered in the development of therapeutic compositions, particularly those materials containing a biologically active material that is poorly soluble in water at physiological pH.\",\n \"An active material's bioavailability is the degree to which the active material becomes available to the target tissue in the body after systemic administration through, for example, oral or intravenous means.\",\n \"Many factors affect bioavailability, including the form of dosage and the solubility and dissolution rate of the active material.\",\n \"Poorly and slowly water-soluble materials tend to be eliminated from the gastrointestinal tract before being absorbed into the circulation.\",\n \"In addition, poorly soluble active agents tend to be disfavored or even unsafe for intravenous administration due to the risk of particles of agent blocking blood flow through capillaries.\",\n \"It is known that the rate of dissolution of a particulate drug will increase with increasing surface area.\",\n \"One way of increasing surface area is decreasing particle size.\",\n \"Consequently, methods of making finely divided or sized drugs have been studied with a view to controlling the size and size range of drug particles for pharmaceutical compositions.\",\n \"For example, dry milling techniques have been used to reduce particle size and hence influence drug absorption.\",\n \"However, in conventional dry milling the limit of fineness is reached generally in the region of about 100 microns (100,000 nm), at which point material cakes on the milling chamber and prevents any further diminution of particle size.\",\n \"Alternatively, wet grinding may be employed to reduce particle size, but flocculation restricts the lower particle size limit to approximately 10 microns (10,000 nm).\",\n \"The wet milling process, however, is prone to contamination, thereby leading to a bias in the pharmaceutical art against wet milling.\",\n \"Another alternative milling technique, commercial airjet milling, has provided particles ranging in average size from as low as about 1 to about 50 microns (1,000-50,000 nm).\",\n \"There are several approaches currently used to formulate poorly soluble active agents.\",\n \"One approach is to prepare the active agent as a soluble salt.\",\n \"Where this approach cannot be employed, alternate (usually physical) approaches are employed to improve the solubility of the active agent.\",\n \"Alternate approaches generally subject the active agent to physical conditions that change the agent's physical and or chemical properties to improve its solubility.\",\n \"These include process technologies such as micronization, modification of crystal or polymorphic structure, development of oil based solutions, use of co-solvents, surface stabilizers or complexing agents, micro-emulsions, super critical fluid and production of solid dispersions or solutions.\",\n \"More than one of these processes may be used in combination to improve formulation of a particular therapeutic material.\",\n \"Many of these approaches commonly convert a drug into an amorphous state, which generally leads to a higher dissolution rate.\",\n \"However, formulation approaches that result in the production of amorphous material are not common in commercial formulations due to concerns relating to stability and the potential for material to re-crystallize.\",\n \"These techniques for preparing such pharmaceutical compositions tend to be complex.\",\n \"By way of example, a principal technical difficulty encountered with emulsion polymerization is the removal of contaminants, such as unreacted monomers or initiators (which may have undesirable levels of toxicity), at the end of the manufacturing process.\",\n \"Another method of providing reduced particle size is the formation of pharmaceutical drug microcapsules, which techniques include micronizing, polymerisation and co-dispersion.\",\n \"However, these techniques suffer from a number of disadvantages including at least the inability to produce sufficiently small particles such as those obtained by milling, and the presence of co-solvents and/or contaminants such as toxic monomers which are difficult to remove, leading to expensive manufacturing processes.\",\n \"Over the last decade, intense scientific investigation has been carried out to improve the solubility of active agents by converting the agents to ultra fine powders by methods such as milling and grinding.\",\n \"These techniques may be used to increase the dissolution rate of a particulate solid by increasing the overall surface area and decreasing the mean particle size.\",\n \"U.S. Pat.\",\n \"No.\",\n \"6,634,576 discloses examples of wet-milling a solid substrate, such as a pharmaceutically active compound, to produce a “synergetic co-mixture”.\",\n \"International Patent Application PCT/AU2005/001977 (Nanoparticle Composition(s) and Method for Synthesis Thereof) describes, inter alia, a method comprising the step of contacting a precursor compound with a co-reactant under mechanochemical synthesis conditions wherein a solid-state chemical reaction between the precursor compound and the co-reactant produces therapeutically active nanoparticles dispersed in a carrier matrix.\",\n \"Mechanochemical synthesis, as discussed in International Patent Application PCT/AU2005/001977, refers to the use of mechanical energy to activate, initiate or promote a chemical reaction, a crystal structure transformation or a phase change in a material or a mixture of materials, for example by agitating a reaction mixture in the presence of a milling media to transfer mechanical energy to the reaction mixture, and includes without limitation “mechanochemical activation”, “mechanochemical processing”, “reactive milling”, and related processes.\",\n \"International Patent Application PCT/AU2007/000910 (Methods for the preparation of biologically active compounds in nanoparticulate form) describes, inter alia, a method for dry milling raloxifene with lactose and NaCl which produced nanoparticulate raloxifene without significant aggregation problems.\",\n \"One limitation of this method is an upper limit to the drug content that can be successfully milled to produce nanoparticles.\",\n \"For some drugs that require a high dose this limitation may restrict the options available for the production of a commercially viable dosage form.\",\n \"The present invention provides methods for improving the dissolution profile of a biologically active material which ameliorate some of the problems attendant with prior technologies, or provides an alternative thereto.\",\n \"One example of a therapeutic area where this technology could be applied in is the area of acute pain management.\",\n \"Many pain medications such as meloxicam (marketed as Mobic® by pharmaceutical company Boehringer Ingelheim) provides pain relief for chronic pain, but must be taken on a daily basis to maintain an effective therapeutic level.\",\n \"Meloxicam is a poorly water soluble drug which is only slowly absorbed by the body (Tmax is 4-5 hours), so a method such as the present invention which provides for improved dissolution, will likely provide much faster absorption resulting in a more rapid onset of the therapeutic effect.\",\n \"Meloxicam also has a long half life (15-20 hours) that means it only need be taken once a day.\",\n \"By using a method such as the present invention, which provides faster absorption, a drug such as meloxicam, could be transformed from a chronic pain drug to an acute pain drug.\",\n \"For meloxicam this would provide a medication that could provide therapeutic relief for acute pain, with the advantage of sustained pain relief over 24 hours.\",\n \"Meloxicam also has sub-optimal bioavailability at 89% for an oral capsule, compared with an IV dosage form.\",\n \"A component of this sub optimal bioavailability is also likely due to the poor water solubility of this drug.\",\n \"If the low solubility does contribute to this sub optimal bioavailability, the improvement of the dissolution of this drug with a method such as the present invention could provide scope to produce a dosage form with a lower active dose whilst still providing the effective therapeutic dose.\",\n \"Although the background to the present invention is discussed in the context of improving the bioavailability of materials that are poorly or slowly water soluble, the applications of the methods of the present invention are not limited to such, as is evident from the following description of the invention.\",\n \"Further, although the background to the present invention is largely discussed in the context of improving the bioavailability of therapeutic or pharmaceutical compounds, the applications of the methods of the present invention are clearly not limited to such.\",\n \"For example, as is evident from the following description, applications of the methods of the present invention include but are not limited to: nutraceutical and nutritional compounds, complementary medicinal compounds, veterinary therapeutic applications and agricultural chemical applications, such as pesticide, fungicide or herbicide.\",\n \"Furthermore, an application of the current invention would be to materials which contain a biologically active compound such as, but not limited to a therapeutic or pharmaceutical compound, a nutraceutical or nutrient, a complementary medicinal product such as active components in plant or other naturally occurring material, a veterinary therapeutic compound or an agricultural compound such as a pesticide, fungicide or herbicide.\",\n \"Specific examples would be the spice turmeric that contains the active compound curcumin, or flax seed that contains the nutrient ALA an omega-3 fatty acid.\",\n \"As these specific examples indicate this invention could be applied to, but not limited to, a range of natural products such as seeds, cocoa and cocoa solids, coffee, herbs, spices, other plant materials or food materials that contain a biologically active compound.\",\n \"The application of this invention to these types of materials would enable greater availability of the active compound in the materials when used in the relevant application.\",\n \"For example where material subject to this invention is orally ingested the active would be more bioavailable.\",\n \"SUMMARY OF THE INVENTION In one aspect the present invention

\"Inclusion does not constitute an admission is made that any of the references constitute prior art or are part of the common general knowledge of those working in the field to which this invention relates.\",\n \"Throughout this specification, unless the context requires otherwise, the word “comprise” or variations, such as “comprises” or “comprising” will be understood to imply the inclusion of a stated integer, or group of integers, but not the exclusion of any other integers or group of integers.\",\n \"It is also noted that in this disclosure, and particularly in the claims and/or paragraphs, terms such as “comprises”, “comprised”, “comprising” and the like can have the meaning attributed to it in US patent law; e.g., they can mean “includes”, “included”, “including”, and the like.\",\n \"“Therapeutically effective amount” as used herein with respect to methods of treatment and in particular drug dosage, shall mean that dosage that provides the specific pharmacological response for which the drug is administered in a significant number of subjects in need of such treatment.\",\n \"It is emphasized that “therapeutically effective amount,” administered to a particular subject in a particular instance will not always be effective in treating the diseases described herein, even though such dosage is deemed a “therapeutically effective amount” by those skilled in the art.\",\n \"It is to be further understood that drug dosages are, in particular instances, measured as oral dosages, or with reference to drug levels as measured in blood.\",\n \"The term “inhibit” is defined to include its generally accepted meaning which includes prohibiting, preventing, restraining, and lowering, stopping, or reversing progression or severity, and such action on a resultant symptom.\",\n \"As such the present invention includes both medical therapeutic and prophylactic administration, as appropriate.\",\n \"The term “biologically active material” is defined to mean a biologically active compound or a substance which comprises a biologically active compound.\",\n \"In this definition, a compound is generally taken to mean a distinct chemical entity where a chemical formula or formulas can be used to describe the substance.\",\n \"Such compounds would generally, but not necessarily be identified in the literature by a unique classification system such as a CAS number.\",\n \"Some compounds may be more complex and have a mixed chemical structure.\",\n \"For such compounds they may only have a empirical formula or be qualitatively identified.\",\n \"A compound would generally be a pure material, although it would be expected that up to 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% of the substance could be other impurities and the like.\",\n \"Examples of biologically active compounds are, but not limited to, pharmaceutical actives, fungicides, pesticides, herbicides, nutraceuticals, cosmeceuticals, cosmetics, complementary medicines, natural products, vitamins, nutrients, biologics, amino acids, proteins, peptides, nucleotides, nucleic acids.\",\n \"A substance that contains a biologically active compound is any substance which has as one of its components a biologically active compound .\",\n \".\",\n \".\",\n \".\",\n \"Examples of substances containing biologically active compounds are, but not limited to, pharmaceutical formulations and products, cosmetic formulations and products, industrial formulations and products, agricultural formulations and products, foods, seeds, cocoa and cocoa solids, coffee, herbs, spices, other plant materials, minerals, animal products, shells and other skeletal material.\",\n \"Any of the terms, “biological(ly) active”, “active”, “active material” shall have the same meaning as biologically active material.\",\n \"The term “grinding matrix” is defined as any inert substance that a biologically active material can or is combined with and milled.\",\n \"The terms “co-grinding matrix” and “matrix” are interchangeable with “grinding matrix”.\",\n \"Particle Size There are a wide range of techniques that can be utilized to characterize the particle size of a material.\",\n \"Those skilled in the art also understand that almost all these techniques do not physically measure the actually particle size, as one might measure something with a ruler, but measure a physical phenomena which is interpreted to indicate a particle size.\",\n \"As part of the interpretation process some assumptions need to be made to enable mathematical calculations to be made.\",\n \"These assumptions deliver results such as an equivalent spherical particle size, or a hydrodynamic radius.\",\n \"Amongst these various methods, two types of measurements are most commonly used.\",\n \"Photon correlation spectroscopy (PCS), also known as ‘dynamic light scattering’ (DLS) is commonly used to measure particles with a size less than 10 micron.\",\n \"Typically this measurement yields an equivalent hydrodynamic radius often expressed as the average size of a number distribution.\",\n \"The other common particle size measurement is laser diffraction which is commonly used to measure particle size from 100 nm to 2000 micron.\",\n \"This technique calculates a volume distribution of equivalent spherical particles that can be expressed using descriptors such as the median particle size or the % of particles under a given size.\",\n \"Those skilled in the art recognize that different characterization techniques such as photon correlation spectroscopy and laser diffraction measure different properties of a particle ensemble.\",\n \"As a result multiple techniques will give multiple answers to the question, “what is the particle size.” In theory one could convert and compare the various parameters each technique measures, however, for real world particle systems this is not practical.\",\n \"As a result the particle size used to describe this invention will be given as two different sets of values that each relate to these two common measurement techniques, such that measurements could be made with either technique and then evaluated against the description of this invention.\",\n \"For measurements made using a photo correlation spectroscopy instrument, or an equivalent method known in the art, the term “number average particle size” is defined as the average particle diameter as determined on a number basis.\",\n \"For measurements made using a laser diffraction instrument, or an equivalent method known in the art, the term “median particle size” is defined as the median particle diameter as determined on an equivalent spherical particle volume basis.\",\n \"Where the term median is used, it is understood to describe the particle size that divides the population in half such that 50% of the population is greater than or less than this size.\",\n \"The median particle size is often written as D50, D(0.50) or D[0.5] or similar.\",\n \"As used herein D50, D(0.50) or D[0.5] or similar shall be taken to mean ‘median particle size’.\",\n \"The term “Dx of the particle size distribution” refers to the xth percentile of the distribution; thus, D90 refers to the 90th percentile, D95 refers to the 95th percentile, and so forth.\",\n \"Taking D90 as an example this can often be written as, D(0.90) or D[0.9] or similar.\",\n \"With respect to the median particle size and Dx an upper case D or lowercase d are interchangeable and have the same meaning.\",\n \"Another commonly used way of describing a particle size distribution measured by laser diffraction, or an equivalent method known in the art, is to describe what % of a distribution is under or over a nominated size.\",\n \"The term “percentage less than” also written as “%<” is defined as the percentage, by volume, of a particle size distribution under a nominated size—for example the %<1000 nm.\",\n \"The term “percentage greater than” also written as “%>” is defined as the percentage, by volume, of a particle size distribution over a nominated size—for example the %>1000 nm.\",\n \"The particle size used to describe this invention should be taken to mean the particle size as measured at or shortly before the time of use.\",\n \"For example, the particle size is measured 2 months after the material is subject to the milling method of this invention.\",\n \"In a preferred form, the particle size is measured at a time selected from the group consisting of: 1 day after milling, 2 days after milling, 5 days after milling, 1 month after milling, 2 months after milling, 3 months after milling, 4 months after milling, 5 months after milling, 6 months after milling, 1 year after milling, 2 years after milling, 5 years after milling.\",\n \"For many of the materials subject to the methods of this invention the particle size can be easily measured.\",\n \"Where the active material has poor water solubility and the matrix it is milled in has good water solubility the powder can simply be dispersed in an aqueous solvent.\",\n \"In this scenario the matrix dissolves leaving the active material dispersed in the solvent.\",\n \"This suspension can then be measured by techniques such as PCS or laser diffraction.\",\n \"Suitable methods to measure an accurate particle size where the active material has substantive aqueous solubility or the matrix has low solubility in a water based dispersant are outlined below.\",\n \"1.In the circumstance where insoluble matrix such as microcrystalline cellulose prevents the measurement of the active material, separation techniques such as filtration or centrifugation could be used to separate the insoluble matrix from the active material particles.\",\n \"Other ancillary techniques would also be required to determine if any active material was removed by the separation technique so that this could be taken into account.\",\n \"2.In the case where the active material is too soluble in water other solvents could be evaluated for the measurement of particle size.\",\n \"Where a solvent could be found that active material is poorly soluble in but is a good solvent for the matrix a measurement would be relatively straight forward.\",\n \"If such a solvent is difficult to find another approach would be to measure the ensemble of matrix and active material in a solvent (such as iso-octane) which both are insoluble in.\",\n \"Then the powder would be measured in another solvent where the active material is soluble but the matrix is not.\",\n \"Thus with a measurement of the matrix particle size and a measurement of the size of the matrix and active material together an understanding of the active material particle size can be obtained.\",\n \"3.In some circumstances image analysis could be used to obtain information about the particle size distribution of the active material.\",\n \"Suitable image measurement techniques might include transmission electron microscopy (TEM), scanning electron microscopy (SEM), optical microscopy and confocal microscopy.\",\n \"In addition to these standard techniques some additional technique would be required to be used in parallel to differentiate the active material and matrix particles.\",\n \"Depending on the chemical makeup of the materials involved possible techniques could be elemental analysis, raman spectroscopy, FTIR spectroscopy or fluorescence spectroscopy.\",\n \"Other Definitions Throughout this specification, unless the context requires otherwise, the phrase “dry mill” or variations, such as “dry milling”, should be understood to refer to milling in at least the substantial absence of liquids.\",\n \"If liquids are present, they are present in such amounts that the contents of the mill retain the characteristics of a dry powder.\",\n \"“Flowable” means a powder having physical characteristics rendering it suitable for further processing using typical equipment used for the manufacture of pharmaceutical compositions and formulations.\",\n \"Other definitions for selected terms used herein may be found within the detailed description of the invention and apply throughout.\",\n \"Unless otherwise defined, all other scientific and technical terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which the invention belongs.\",\n \"The term “millable” means that the grinding matrix is capable of being physically degraded under the dry milling conditions of the method of the invention.\",\n \"In one embodiment of the invention, the milled grinding matrix is of a comparable particle size to the biologically active material.\",\n \"In another embodiment of the invention the particle size of the matrix is substantially reduced but not as small as the biologically active material Other definitions for selected terms used herein may be found within the detailed description of the invention and apply throughout.\",\n \"Unless otherwise defined, all other scientific and technical terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which the invention belongs.\",\n \"Specific In one embodiment, the present invention is directed to a method for improving the dissolution profile of a biologically active material, the method comprising the step of: dry milling a mixture of a solid biologically active material and a millable grinding matrix, in a mill comprising a plurality of milling bodies, to produce particles of a biologically active material dispersed in at least partially milled grinding matrix.\",\n \"The mixture of active material and matrix may then be separated from the milling bodies and removed from the mill.\",\n \"In one aspect the mixture of active material and matrix is then further processed.\",\n \"In another aspect, the grinding matrix is separated from the particles of biologically active material.\",\n \"In a further aspect, at least a portion of the milled grinding matrix is separated from the particulate biologically active material.\",\n \"The milling bodies are essentially resistant to fracture and erosion in the dry milling process.\",\n \"The quantity of the grinding matrix relative to the quantity of biologically active material in particulate form, and the extent of milling of the grinding matrix, is sufficient to improve the dissolution profile of the active material milled.\",\n \"The present invention also relates to biologically active materials produced by said methods, to medicaments produced using said biologically active materials and to methods of treatment of an animal, including man, using a therapeutically effective amount of said biologically active materials administered by way of said medicaments.\",\n \"Improving the Dissolution Profile The present invention leads to the improved dissolution profile.\",\n \"An improved dissolution profile has significant advantages including the improvement of bioavailability of the biologically active material in vivo.\",\n \"Preferably, the improved dissolution profile is observed in vitro.\",\n \"Alternatively, the improved dissolution profile is observed in vivo by the observation of an improved bioavailability profile.\",\n \"Standard methods for determining the dissolution profile of a material in vitro are available in the art.\",\n \"A suitable method to determine an improved dissolution profile in vitro may include determining the concentration of the sample material in a solution over a period of time and comparing the results from the sample material to a control sample.\",\n \"An observation that peak solution concentration for the sample material was achieved in less time than the control sample would indicate (assuming it is statistically significant), that the sample material has an improved dissolution profile.\",\n \"The measurement sample is herein defined as the mixture of biologically active material with grinding matrix and/or other additives that has been subject to the processes of the invention described here.\",\n \"Herein a control sample is defined as a physical mixture (not subject to the processes described in this invention) of the components in the measurement sample with the same relative proportions of active, matrix and/or additive as the measurement sample.\",\n \"For the purposes of the dissolution testing a prototype formulation of the measurement sample could also be used.\",\n \"In this case the control sample would be formulated in the same way.\",\n \"Standard methods for determining the improved dissolution profile of a material in vivo are available in the art.\",\n \"A suitable method to determine an improved dissolution profile in a human may be after delivering the dose to measure the rate of active material absorption by measuring the plasma concentration of the sample compound over a period of time and comparing the results from the sample compound to a control.\",\n \"An observation that peak plasma concentration for the sample compound was achieved in less time than the control would indicate (assuming it is statistically significant) that the sample compound has improved bioavailability and an improved dissolution profile.\",\n \"Preferably, the improved dissolution profile is observed at a relevant gastrointestinal pH, when it is observed in vitro.\",\n \"Preferably, the improved dissolution profile is observed at a pH which is favourable at indicating improvements in dissolution when comparing the measurement sample to the control compound.\",\n \"Suitable methods for quantifying the concentration of a compound in an in vitro sample or an in vivo sample are widely available in the art.\",\n \"Suitable methods could include the use of spectroscopy or radioisotope labeling.\",\n \"In one preferred embodiment the method of quantification of dissolution is determined in a solution with a pH selected from the group consisting of: pH 1, pH 2, pH 3, pH 4, pH 5, pH 6, pH 7, pH 7.3, pH 7.4, pH 8, pH 9, pH 10, pH 11, pH 12, pH 13, pH 14 or a pH with 0.5 of a pH unit of any of this group.\",\n \"Crystallization Profile Methods for determining the crystallinity profile of the biologically active material are widely available in the art.\",\n \"Suitable methods may include X-ray diffraction, differential scanning calorimetry, raman or IR spectroscopy.\",\n \"Amorphicity Profile Methods for determining the amorphous content of the biologically active material are widely available in the art.\",\n \"Suitable methods may include X-ray diffraction, differential scanning calorimetry, raman or IR spectroscopy.\",\n \"Grinding Matrix As will be described subsequently, selection of an appropriate grinding matrix affords particular advantageous applications of the method of the present invention.\",\n \"A highly advantageous application of the method of the invention is the use of a water-soluble grinding matrix in conjunction with a poorly water-soluble biologically active material.\",\n \"This affords at least two advantages.\",\n \"The first being when the powder containing the biologically active material is placed into water—such as the ingestion of the powder as part of an oral medication—the matrix dissolves, releasing the particulate active material such that there is maximum surface area exposed to solution, thereby allowing a rapid dissolution of the active compound.\",\n \"The second key advantage is the ability, if required, to remove or partially remove the matrix prior to further processing or formulation.\",\n \"Another advantageous application of the method of the invention is the use of a water-insoluble grinding matrix, particularly in the area of agricultural use, when a biologically active material such as a fungicide is commonly delivered as part of a dry powder or a suspension.\",\n \"The presence of a water insoluble matrix will afford benefits such as increased rain fastness.\",\n \"Without wishing to be bound by theory, it is believed that the physical degradation (including but not limited to particle size reduction) of the millable grinding matrix affords the advantage of the invention, by acting as a more effective diluent than grinding matrix of a larger particle size.\",\n \"Again, as will be described subsequently, a highly advantageous aspect of the present invention is that certain grinding matrixes appropriate for use in the method of the invention are also appropriate for use in a medicament.\",\n \"The present invention encompasses methods for the production of a medicament incorporating both the biologically active material and the grinding matrix or in some cases the biologically active material and a portion of the grinding matrix, medicaments so produced, and methods of treatment of an animal, including man, using a therapeutically effective amount of said biologically active materials by way of said medicaments.\",\n \"Analogously, as will be described subsequently, a highly advantageous aspect of the present invention is that certain grinding matrixes appropriate for use in the method of the invention are also appropriate for use in a carrier for an agricultural chemical, such as a pesticide, fungicide, or herbicide.\",\n \"The present invention encompasses methods for the production of an agricultural chemical composition incorporating both the biologically active material in particulate form and the grinding matrix, or in some cases the biologically active material, and a portion of the grinding matrix, and agricultural chemical compositions so produced.\",\n \"The medicament may include only the biologically active material together with the milled grinding matrix or, more preferably, the biologically active material and milled grinding matrix may be combined with one or more pharmaceutically acceptable carriers, as well as any desired excipients or other like agents commonly used in the preparation of medicaments.\",\n \"Analogously, the agricultural chemical composition may include only the biologically active material together with the milled grinding matrix or, more preferably, the biologically active materials and milled grinding matrix may be combined with one or more carriers, as well as any desired excipients or other like agents commonly used in the preparation of agricultural chemical compositions.\",\n \"In one particular form of the invention, the grinding matrix is both appropriate for use in a medicament and readily separable from the biologically active material by methods not dependent on particle size.\",\n \"Such grinding matrixes are described in the following detailed description of the invention.\",\n \"Such grinding matrixes are highly advantageous in that they afford significant flexibility in the extent to which the grinding matrix may be incorporated with the biologically active material into a medicament.\",\n \"In a highly preferred form, the grinding matrix is harder than the biologically active material, and is thus capable of improving the dissolution profile of the active material under the dry milling conditions of the invention.\",\n \"Again without wishing to be bound by theory, under these circumstances it is believed that the millable grinding matrix affords the advantage of the present invention through a second route, with the smaller particles of grinding matrix produced under the dry milling conditions enabling greater interaction with the biologically active material.\",\n \"The quantity of the grinding matrix relative to the quantity of biologically active material, and the extent of physical degradation of the grinding matrix, is sufficient to improve the dissolution profile of the milled biologically active material.\",\n \"The grinding matrix is not generally selected to be chemically reactive with the biologically active material under the milling conditions of the invention, excepting for example, where the matrix is deliberately chosen to undergo a mechanico-chemical reaction.\",\n \"Such a reaction might be the conversion of a free base or acid to a salt or vice versa.\",\n \"As stated above, the method of the present invention requires the grinding matrix to be milled with the biologically active material; that is, the grinding matrix will physically degrade under the dry milling conditions of the invention to facilitate the formation and retention of particulates of the biologically active material with improved dissolution profiles.\",\n \"The precise extent of degradation required will depend on certain properties of the grinding matrix and the biologically active material, the ratio of biologically active material to grinding matrix, and the particle size distribution of the particles comprising the biologically active material.\",\n \"The physical properties of the grinding matrix necessary to achieve the requisite degradation are dependent on the precise milling conditions.\",\n \"For example, a harder grinding matrix may degrade to a sufficient extent provided [it is subjected to] more vigorous dry milling conditions.\",\n \"Physical properties of the grinding matrix relevant to the extent that the agent will degrade under dry milling conditions include hardness, friability, as measured by indicia such as hardness, fracture toughness and brittleness index.\",\n \"A low hardness (typically a Mohs Hardness less than 7) of the biologically active material is desirable to ensure fracture of the particles during processing, so that composite microstructures develop during milling.\",\n \"Preferably, the hardness is less than 3 as determined using the Mohs Hardness scale.\",\n \"Preferably, the grinding matrix is of low abrasivity.\",\n \"Low abrasivity is desirable to minimise contamination of the mixture of the biologically active material in the grinding matrix by the milling bodies and/or the milling chamber of the media mill.\",\n \"An indirect indication of the abrasivity can be obtained by measuring the level of milling-based contaminants.\",\n \"Preferably, the grinding matrix has a low tendency to agglomerate during dry milling.\",\n \"While it is difficult to objectively quantify the tendency to agglomerate during milling, it is possible to obtain a subjective measure by observing the level of “caking” of the grinding matrix on the milling bodies and the milling chamber of the media mill as dry milling progresses.\",\n \"The grinding matrix may be an inorganic or organic substance.\",\n \"In one embodiment, the grinding matrix is selected from the following, either as a single substance

removed, the relative concentration of pharmaceutically acceptable materials in the composition may be considerably higher depending on the amount of the grinding matrix that is removed.\",\n \"For example, if all of the grinding matrix is removed the concentration of particles in the preparation may approach 100% by weight (subject to the presence of facilitating agents).\",\n \"Compositions produced according to the present invention are not limited to the inclusion of a single species of pharmaceutically acceptable materials.\",\n \"More than one species of pharmaceutically acceptable materials may therefore be present in the composition.\",\n \"Where more than one species of pharmaceutically acceptable materials is present, the composition so formed may either be prepared in a dry milling step, or the pharmaceutically acceptable materials may be prepared separately and then combined to form a single composition.\",\n \"Medicaments The medicaments of the present invention may include the pharmaceutically acceptable material, optionally together with the grinding matrix or at least a portion of the grinding matrix, combined with one or more pharmaceutically acceptable carriers, as well as other agents commonly used in the preparation of pharmaceutically acceptable compositions.\",\n \"As used herein “pharmaceutically acceptable carrier” includes any and all

suitable for parenteral administration, intravenous, intraperitoneal, intramuscular, sublingual, pulmonary, transdermal or oral administration.\",\n \"Pharmaceutically acceptable carriers include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersion.\",\n \"The use of such media and agents for the manufacture of medicaments is well known in the art.\",\n \"Except insofar as any conventional media or agent is incompatible with the pharmaceutically acceptable material, use thereof in the

acceptable excipients.\",\n \"Medicaments of the invention suitable for use in animals and in particular in man typically must be sterile and stable under the conditions of manufacture and storage.\",\n \"The medicaments of the invention comprising the biologically active material can be formulated as a solid, a solution, a microemulsion, a liposome, or other ordered structures suitable to high drug concentration.\",\n \"Actual dosage levels of the biologically active material in the medicament of the invention may be varied in accordance with the nature of the biologically active material, as well as the potential increased efficacy due to the advantages of providing and administering the biologically active material (e.g., increased solubility, more rapid dissolution, increased surface area of the biologically active material, etc.).\",\n \"Thus as used herein “therapeutically effective amount” will refer to an amount of biologically active material required to effect a therapeutic response in an animal.\",\n \"Amounts effective for such a use will depend on: the desired therapeutic effect; the route of administration; the potency of the biologically active material; the desired duration of treatment; the stage and severity of the disease being treated; the weight and general state of health of the patient; and the judgment of the prescribing physician.\",\n \"In another embodiment, the biologically active material, optionally together with the grinding matrix or at least a portion of the grinding matrix, of the invention may be combined into a medicament with another biologically active material, or even the same biologically active material.\",\n \"In the latter embodiment, a medicament may be achieved which provides for different release characteristics—early release from the biologically active material, and later release from a larger average size biologically active material.\",\n \"Modes of Administration of Medicaments Comprising Biologically Active Materials Medicaments of the invention can be administered to animals, including man, in any pharmaceutically acceptable manner, such as orally, rectally, pulmonary, intravaginally, locally (powders, ointments or drops), transdermal, parenteral administration, intravenous, intraperitoneal, intramuscular, sublingual or as a buccal or nasal spray Solid dosage forms for oral administration include capsules, tablets, pills, powders, pellets, and granules.\",\n \"Further, incorporating any of the normally employed excipients, such as those previously listed, and generally 5-95% of the biologically active agent, and more preferably at a concentration of 10%-75% will form a pharmaceutically acceptable non-toxic oral composition.\",\n \"Medicaments of the invention may be parenterally administered as a solution of the biologically active agent suspended in an acceptable carrier, preferably an aqueous carrier.\",\n \"A variety of aqueous carriers may be used, e.g.\",\n \"water, buffered water, 0.4% saline, 0.3% glycine, hyaluronic acid and the like.\",\n \"These compositions may be sterilized by conventional, well known sterilization techniques, or may be sterile filtered.\",\n \"The resulting aqueous solutions may be packaged for use as is, or lyophilized, the lyophilized preparation being combined with a sterile solution prior to administration.\",\n \"For aerosol administration, medicaments of the invention are preferably supplied along with a surfactant or polymer and propellant.\",\n \"The surfactant or polymer must, of course, be non-toxic, and preferably soluble in the propellant.\",\n \"Representative of such agents are the esters or partial esters of fatty acids containing from 6 to 22 carbon atoms, such as caproic, octanoic, lauric, palmitic, stearic, linoleic, linolenic, olesteric and oleic acids with an aliphatic polyhydric alcohol or its cyclic anhydride.\",\n \"Mixed esters, such as mixed or natural glycerides may be employed.\",\n \"The surfactant or polymer may constitute 0.1%-20% by weight of the composition, preferably 0.25-5%.\",\n \"The balance of the composition is ordinarily propellant.\",\n \"A carrier can also be included, as desired, as with, e.g., lecithin for intranasal delivery.\",\n \"Medicaments of the invention may also be administered via liposomes, which serve to target the active agent to a particular tissue, such as lymphoid tissue, or targeted selectively to cells.\",\n \"Liposomes include emulsions, foams, micelles, insoluble monolayers, liquid crystals, phospholipid dispersions, lamellar layers and the like.\",\n \"In these preparations the composite microstructure composition is incorporated as part of a liposome, alone or in conjunction with a molecule that binds to or with other therapeutic or immunogenic compositions.\",\n \"As described above, the biologically active material can be formulated into a solid dosage form (e.g., for oral or suppository administration), together with the grinding matrix or at least a portion of it.\",\n \"In this case there may be little or no need to add stabilizing agents since the grinding matrix may effectively act as a solid-state stabilizer.\",\n \"However, if the biologically active material is to be utilized in a liquid suspension, the particles comprising the biologically active material may require further stabilization once the solid carrier has been substantially removed to ensure the elimination, or at least minimisation of particle agglomeration.\",\n \"Therapeutic Uses Therapeutic uses of the medicaments of the invention include pain relief, anti-inflammatory, migraine, asthma, and other disorders that require the active agent to be administered with a high bioavailability.\",\n \"One of the main areas when rapid bioavailability of a biologically active material is required is in the relief of pain.\",\n \"The minor analgesics, such as cyclooxgenase inhibitors (aspirin related drugs) may be prepared as medicaments according to the present invention.\",\n \"Medicaments of the invention may also be used for treatment of eye disorders.\",\n \"That is, the biologically active material may be formulated for administration on the eye as an aqueous suspension in physiological saline, or a gel.\",\n \"In addition, the biologically active material may be prepared in a powder form for administration via the nose for rapid central nervous system penetration.\",\n \"Treatment of cardiovascular disease may also benefit from biologically active materials according to the invention, such as treatment of angina pectoris and, in particular, molsidomine may benefit from better bioavailability.\",\n \"Other therapeutic uses of the medicaments of the present invention include treatment of hair loss, sexual dysfunction, or dermal treatment of psoriasis.\",\n \"The present invention will now be described with reference to the following non-limiting Examples.\",\n \"The description of the Examples is in no way limiting on the preceding paragraphs of this specification, but is provided for exemplification of the methods and compositions of the invention.\",\n \"EXAMPLES It will be apparent to persons skilled in the milling and pharmaceutical arts that numerous enhancements and modifications can be made to the above

some cases where two dictionaries are used for a two-step encoding process to improve a compression ratio, the process time of the above conventional encoding process is long.","In an aspect, it is an object of the present disclosure to improve the efficiency of the two-step encoding process on a text to be encoded.","An embodiment will now be described in detail with reference to the drawings.","The document information storage apparatus in PTL 1 encodes a document in a manner in which a code that is recorded in a postal code dictionary, a synonym dictionary, or another dictionary is assigned to one or more morphemes that are extracted from the document by using morphological analysis.","FIG.","1 illustrates an example of a morphological analysis dictionary used in morphological analysis.","The morphological analysis dictionary in FIG.","1 includes morphemes, parts of speech, and codes.","The parts of speech represent the parts of speech of the morphemes.","The codes represent the codes that are associated with the respective morphemes.","FIG.","2 illustrates an example of the postal code dictionary.","The postal code dictionary in FIG.","2 includes strings and codes.","The strings each include morphemes representing an address to which a postal code is assigned.","The codes represent the postal codes that are associated with the respective strings.","FIG.","3 illustrates an example of an encoding process with the morphological analysis dictionary in FIG.","1 and the postal code dictionary in FIG.","2.In the case where a text 301 to be encoded that is “Kanagawa Ken Kawasaki Shi Nakahara Ku Kamikodanaka in Live” is inputted, the text 301 to be encoded is first divided into morphemes by morphological analysis in a first pass.","Each morpheme is converted into a code recorded in the morphological analysis dictionary, and an encoded text 302 is created.","For example, “Kanagawa” that is the front morpheme in the text 301 to be encoded is converted into a hexadecimal code of 0×0105.Subsequently, encoding in a second pass is performed such that strings included in the encoded text 302 are compared with strings recorded in the postal code dictionary, and, in the case where the two strings match with each other, the strings are converted into the codes recorded in the postal code dictionary, and an encoded text 303 is created.","According to this example, a string that is “Kanagawa Ken Kawasaki Shi Nakahara Ku Kamikodanaka” is converted into a code of 211-0053.Thus, the encoding in the second pass enables the result of encoding in the first pass to be further compressed because the morphemes representing the address are converted into the code.","During the morphological analysis in the first pass, the morphological analysis dictionary is used to rapidly extract the morphemes, each of which is a minimum unit having a part of speech or a meaning.","In the morphological analysis dictionary, a single code is assigned to a single morpheme.","During the encoding in the second pass, the postal code dictionary is used to rapidly extract the strings representing the addresses.","In the postal code dictionary, a single code is assigned to morphemes.","The number of the morphemes, to which the code is assigned, differs between the two dictionaries as above.","Accordingly, the encoding process is divided into two passes (two steps) of the first pass and the second pass.","The two-pass encoding process takes a longer time and uses more calculation resources such as storage areas than a single-pass encoding process.","FIG.","4 illustrates an example of the morphological analysis dictionary to which the codes in the postal code dictionary are added to perform the same process as the two-pass encoding process in a single pass.","In the morphological analysis dictionary in FIG.","4, a string that is “Kanagawa Ken Kawasaki Shi Nakahara Ku Kamikodanaka” is recorded as the morpheme and associated with a code of 211-0053.However, the frequency of appearance of the string representing the address in the text is lower than the frequency of appearance of the morphemes representing place names included in the address.","Accordingly, in the case where the morphemes are extracted in descending order of the statistical frequency of appearance during the morphological analysis, the string representing the address is much less likely to be extracted.","For this reason, the encoded text 303 is not created from the text 301 to be encoded but the encoded text 302 is created even when the morphological analysis dictionary in FIG.","4 is used.","Consequently, the codes in the postal code dictionary are not used, and the compression ratio is not improved.","During the encoding in the second pass, the postal code dictionary is searched for all of the morphemes of the result of the morphological analysis in an exact longest match manner to assign one of the codes in the postal code dictionary to the string representing the address.","In this case, the postal code dictionary is referred the same number of times as the number of the morphemes for an exact longest match search, and this takes an enormous amount of time.","This problem is not limited to the case where the postal code dictionary is used during the encoding in the second pass and arises also in the case where a dictionary that includes other strings other than the address is used.","FIG.","5 illustrates an example of a functional structure of an encoding apparatus according to the embodiment.","An encoding apparatus 501 in FIG.","5 includes a storage unit 511, an encoder 512, and an output unit 513.The storage unit 511 stores morpheme segment information 521 and string encoding information 522.The string encoding information 522 includes records.","A recorded string and a code that is associated with the recorded string are recorded in each of the records.","The morpheme segment information 521 includes records including respective morphemes and is used to segment the morphemes.","The morpheme segment information 521 includes records including the respective front morphemes of the recorded strings of the records included in the string encoding information 522.The encoder 512 encodes a text to be encoded based on the morpheme segment information 521 and the string encoding information 522 and creates the encoded text.","The output unit 513 outputs the encoded text.","FIG.","6 is a flowchart of an example of the encoding process that the encoding apparatus 501 in FIG.","5 performs.","The encoder 512 first analyzes the text to be encoded based on the morpheme segment information 521 (step 601).","The encoder 512 searches the string encoding information for a string to be encoded that begins with one of the morphemes and that is included in the text to be encoded in response to identification of the one of the morphemes included in the record corresponding to one of the recorded strings among the records included in the morpheme segment information 521 (step 602).","When the string to be encoded corresponds to the one of the recorded strings, the encoder 512 converts the string to be encoded into the code associated with the one of the recorded strings (step 603).","The output unit 513 outputs the encoded text that includes the code after conversion (step 604).","The encoding apparatus 501 can improve the efficiency of the two-step encoding process on the text to be encoded.","FIG.","7 illustrates a specific example of the encoding apparatus 501 in FIG.","5.The encoder 512 in FIG.","7 includes an analyzer 711, a determining unit 712, a converter 713, and a converter 714.The storage unit 511 stores a morphological analysis dictionary 721 and an address dictionary 722.The morphological analysis dictionary 721 and the address dictionary 722 correspond to the morpheme segment information 521 and the string encoding information 522 in FIG.","5, respectively.","FIG.","8 illustrates an example of the morphological analysis dictionary 721.The morphological analysis dictionary 721 in FIG.","8 includes morphemes, the parts of speech, codes, and flags.","The parts of speech represent the parts of speech of the morphemes.","The codes represent the codes that are associated with the respective morphemes.","The flags

flag value of a logic “0” represents that switching is not performed.","According to this example, the flags corresponding to the front morphemes of the strings representing the prefectures are set to a logic “1”.For example, the part of speech of “Tokyo” is a noun, the code thereof is C1,and the flag thereof is a logic “1”.","The part of speech of “Kawasaki” is a noun, the code thereof is C4, and the flag thereof is a logic “0”.","FIG.","9 illustrates an example of the address dictionary 722.The address dictionary 722 in FIG.","9 includes strings and codes.","The strings include the morphemes representing the address.","The codes represent the codes that are associated with the respective strings.","The codes may be the postal codes.","The strings recorded in the address dictionary 722 are divided into blocks corresponding to the prefectures.","A separator 901 represents the start position of a block for “Tokyo To”.","A separator 902 represents the start position of a block for “Kanagawa Ken”.","For example, the code of “Tokyo To Suginami Ku” is D1.The code of “Kanagawa Ken Kawasaki Shi Nakahara Ku” is D3.The analyzer 711 sets the switch information in the morphological analysis dictionary 721 and performs the morphological analysis on the text to be encoded based on the morphological analysis dictionary 721 to divide the text to be encoded into the morphemes.","The determining unit 712 determines whether switching to the address dictionary 722 is performed for each morpheme created by the analyzer 711.The converter 713 converts the morphemes into the codes in the morphological analysis dictionary 721.The converter 714 converts the morphemes representing the address into the code in the address dictionary 722.FIG.","10 is a flowchart of an example of a process of setting the switch information that the analyzer 711 performs.","At the beginning of the process of setting the switch information, the flags of all of the morphemes in the morphological analysis dictionary 721 are set to a logic “0”.","The analyzer 711 first performs the morphological analysis on the strings recorded in the address dictionary 722 based on the morphological analysis dictionary 721 to divide the strings into the morphemes (step 1001).","The analyzer 711 selects the front morpheme of each string from the morphemes in the morphological analysis dictionary 721, changes the flag of the selected morpheme to a logic “1” to set the switch information (step 1002).","The analyzer 711 may set a pointer representing the start position of each block in the address dictionary 722 as the switch information instead of the flag.","In this case, a pointer representing the position of the separator 901 is set as the switch information for “Tokyo”, and a pointer representing the position of the separator 902 is set as the switch information for “Kanagawa”.","FIG.","11 is a flowchart of a specific example of the encoding process that the encoding apparatus 501 in FIG.","7 performs.","The analyzer 711 first performs the morphological analysis on the text to be encoded based on the morphological analysis dictionary 721 (step 1101) to extract the morphemes from the text to be encoded in order from the front (step 1102).","Subsequently, the determining unit 712 determines whether the switch information for each morpheme extracted by the analyzer 711 in the morphological analysis dictionary 721 represents switching (step 1103).","In the case where the switch information represents switching (step 1103, YES), the determining unit 712 searches the address dictionary 722 for a string to be encoded (morpheme group) that begins with the extracted morpheme and that is included in the text to be encoded (step 1104).","At this time, the determining unit 712 searches the block indicated by the switch information for the string to be encoded and checks whether the string to be encoded is recorded in the block.","The determining unit 712 can check whether the string to be encoded is recorded in the block in a manner in which the string to be encoded and each recorded string in the block are compared by using, for example, the exact longest match search.","In the case where the string to be encoded is recorded in the address dictionary 722 (step 1104, YES), the converter 714 converts the string to be encoded into the code recorded in the address dictionary 722 (step 1105).","The determining unit 712 checks whether the last morpheme in the text to be encoded is converted into the code (step 1106).","In the case where the last morpheme is not converted into the code (step 1106, NO), the determining unit 712 repeatedly performs the processes at the step 1101 and later on the remaining text.","In the case where the switch information does not represent switching (step 1103, NO), the converter 713 converts each morpheme extracted by the analyzer 711 into the code recorded in the morphological analysis dictionary 721 (step 1108).","The encoder 512 performs the processes at the step 1106 and later.","In the case where the string to be encoded is not recorded in the address dictionary 722 (step 1104, NO), the encoder 512 performs the processes at the step 1108 and later.","In the case where the last morpheme is converted into the code (step 1106, YES), the output unit 513 outputs the encoded text that includes a row of the codes (step 1107).","For example, a text to be encoded that is “Kanagawa Ken Kawasaki Shi Nakahara Ku In Live” is divided into “Kanagawa/Ken/Kawasaki/Shi/Nakahara/Ku/In/Live”.","In the morphological analysis dictionary 721 in FIG.","8, the flag “1” for “Kanagawa” represents switching, the block for “Kanagawa” in the address dictionary 722 in FIG.","9 is searched for a string that begins with “Kanagawa”, and a recorded string that is “Kanagawa Ken Kawasaki Shi Nakahara Ku” is detected.","Then, “Kanagawa/Ken/Kawasaki/Shi/Nakahara/Ku” is converted into the corresponding code D3, and the following “In” and “Live” are converted into the codes in the morphological analysis dictionary 721.In the case where the pointers are used in the morphological analysis dictionary 721 instead of the flags, the presence of a pointer corresponding to the morphemes results in determination that the switch information represents switching, and the absence of a pointer results in determination that the switch information does not represent switching.","In this encoding process, the morphological analysis dictionary 721 is switched to the address dictionary 722 when each recorded string in the address dictionary 722 appears, and accordingly, the two-pass encoding process can be performed in a single pass.","This enables the two-step encoding process to be speeded up and reduces calculation resources such as storage areas used for the encoding process.","The recorded strings are divided into the blocks corresponding to the front morphemes and recorded in the address dictionary 722.This enables the subject of the search to be limited to the block corresponding to the front morpheme of the string to be encoded.","Consequently, the blocks to be searched are limited, and the efficiency of the search process is improved.","However, in the encoding process in FIG.","11, whenever the switch information representing switching is detected, the string to be encoded included in the text to be encoded is compared with all of the recorded strings in the corresponding block in the address dictionary 722 by using the exact longest match search.","For this reason, in the case where a large number of the recorded strings are included in the block, the search process at the step 1104 takes a long time.","For example, a text to be encoded that is “Kanagawa To Go” is divided into “Kanagawa/To/Go”.","In the morphological analysis dictionary 721 in FIG.","8, the flag “1” for “Kanagawa” represents switching, and the address dictionary 722 is searched for a string that begins with “Kanagawa”.","However, none of the recorded strings in the address dictionary 722 include “To”.","For this reason, “Kanagawa” is converted into the code in the morphological analysis dictionary 721.In the case where one of the morphemes in the text to be encoded matches one of the front morphemes of the recorded strings in the address dictionary 722, but the string to be encoded that begins with the morpheme matches none of the recorded strings in the address dictionary 722 as described above, the search time wastes.","In view of this, it is preferable that search for strings that are not recorded in the address dictionary 722 be omitted to further speed up the encoding process.","FIG.","12 illustrates a specific example of the encoding apparatus 501 in which search for strings that are not recorded in the address dictionary 722 is omitted.","The structure of the encoding apparatus 501 in FIG.","12 is the same as in the encoding apparatus 501 in FIG.","7.The storage unit 511 stores morpheme position information 1211 in addition to the morphological analysis dictionary 721 and the address dictionary 722 and includes a working area 1212.The morpheme position information 1211 represents a recorded-string position of each morpheme included in the recorded strings in the address dictionary 722.The working area 1212 is used to determine whether a string is recorded in the address dictionary 722 by using the morpheme position information 1211 and may be a stack.","FIG.","13 illustrates an example of the address dictionary 722 in which the addresses of the prefectures are divided into the blocks.","“Tokyo 1” and “Tokyo 2” represent the address block name of “Tokyo To”, and “Kanagawa 1” to “Kanagawa 5” represent the address block name of “Kanagawa Ken”.","FIG.","14 illustrates an example of the morpheme position information 1211 corresponding to the address dictionary 722 in FIG.","13.The morpheme position information 1211 in FIG.","14 includes morphemes, offsets, and filter information about the blocks of the prefectures.","The morphemes represent the morphemes included in the recorded strings in the address dictionary 722.The offsets represent the recorded-string positions of the morphemes.","For example, a combination of “Tokyo” and the offset “1” represents that the front morpheme of the recorded string is “Tokyo”, and a combination of “Tama” and the offset “3” represents that the third morpheme of the recorded string is “Tama”.","The filter information is expressed by a bit string that includes bit values the number of which is equal to the number of the blocks.","When one of the bit values for a block is a logic “1”, one of the recorded strings included in the block includes the morpheme at a position represented by the offset.","When one of the bit values for a block is a logic “0”, all of the recorded strings included in the block do not include the morpheme at a position represented by the offset.","For example, the bit value “1” for “Tokyo 1” corresponding to the combination of “Tokyo” and the offset “1” represents that the block for “Tokyo 1” includes a recorded string in which the front morpheme is “Tokyo”.","The bit value “0” for “Kanagawa 1” corresponding to the combination of “Tokyo” and the offset “1” represents that the block for “Kanagawa 1” includes no recorded string in which the front morpheme is “Tokyo”.","The bit value “1” for “Tokyo 1” corresponding to the combination of “Tama” and the offset “3” represents that the block for “Tokyo 1” includes a recorded string in which the third morpheme is “Tama”.","The bit value “1” for “Kanagawa 3” corresponding to a combination of “Tama” and the offset “5” represents that the block for “Kanagawa 3” includes a recorded string in which the fifth morpheme is “Tama”.","The use of the morpheme position information 1211 enables determination whether a string to be encoded is recorded in the address dictionary 722 without comparison between the string to be encoded and the recorded strings.","In addition, in the case where the string to be encoded is recorded in the address dictionary 722, the block that includes the string to be encoded can be narrowed from the blocks corresponding to the same front morpheme.","FIG.","15 is a flowchart of a specific example of the encoding process that the encoding apparatus 501 in FIG.","12 performs.","Processes at step 1501 to step 1503 and step 1506 to step 1509 are the same as the processes at the step 1101 to the step 1103 and the step 1105 to the step 1108 in

encoding process is long.\",\n \"In an aspect, it is an object of the present disclosure to improve the efficiency of the two-step encoding process on a text to be encoded.\",\n \"An embodiment will now be described in detail with reference to the drawings.\",\n \"The document information storage apparatus in PTL 1 encodes a document in a manner in which a code that is recorded in a postal code dictionary, a synonym dictionary, or another dictionary is assigned to one or more morphemes that are extracted from the document by using morphological analysis.\",\n \"FIG.\",\n \"1 illustrates an example of a morphological analysis dictionary used in morphological analysis.\",\n \"The morphological analysis dictionary in FIG.\",\n \"1 includes morphemes, parts of speech, and codes.\",\n \"The parts of speech represent the parts of speech of the morphemes.\",\n \"The codes represent the codes that are associated with the respective morphemes.\",\n \"FIG.\",\n \"2 illustrates an example of the postal code dictionary.\",\n \"The postal code dictionary in FIG.\",\n \"2 includes strings and codes.\",\n \"The strings each include morphemes representing an address to which a postal code is assigned.\",\n \"The codes represent the postal codes that are associated with the respective strings.\",\n \"FIG.\",\n \"3 illustrates an example of an encoding process with the morphological analysis dictionary in FIG.\",\n \"1 and the postal code dictionary in FIG.\",\n \"2.In the case where a text 301 to be encoded that is “Kanagawa Ken Kawasaki Shi Nakahara Ku Kamikodanaka in Live” is inputted, the text 301 to be encoded is first divided into morphemes by morphological analysis in a first pass.\",\n \"Each morpheme is converted into a code recorded in the morphological analysis dictionary, and an encoded text 302 is created.\",\n \"For example, “Kanagawa” that is the front morpheme in the text 301 to be encoded is converted into a hexadecimal code of 0×0105.Subsequently, encoding in a second pass is performed such that strings included in the encoded text 302 are compared with strings recorded in the postal code dictionary, and, in the case where the two strings match with each other, the strings are converted into the codes recorded in the postal code dictionary, and an encoded text 303 is created.\",\n \"According to this example, a string that is “Kanagawa Ken Kawasaki Shi Nakahara Ku Kamikodanaka” is converted into a code of 211-0053.Thus, the encoding in the second pass enables the result of encoding in the first pass to be further compressed because the morphemes representing the address are converted into the code.\",\n \"During the morphological analysis in the first pass, the morphological analysis dictionary is used to rapidly extract the morphemes, each of which is a minimum unit having a part of speech or a meaning.\",\n \"In the morphological analysis dictionary, a single code is assigned to a single morpheme.\",\n \"During the encoding in the second pass, the postal code dictionary is used to rapidly extract the strings representing the addresses.\",\n \"In the postal code dictionary, a single code is assigned to morphemes.\",\n \"The number of the morphemes, to which the code is assigned, differs between the two dictionaries as above.\",\n \"Accordingly, the encoding process is divided into two passes (two steps) of the first pass and the second pass.\",\n \"The two-pass encoding process takes a longer time and uses more calculation resources such as storage areas than a single-pass encoding process.\",\n \"FIG.\",\n \"4 illustrates an example of the morphological analysis dictionary to which the codes in the postal code dictionary are added to perform the same process as the two-pass encoding process in a single pass.\",\n \"In the morphological analysis dictionary in FIG.\",\n \"4, a string that is “Kanagawa Ken Kawasaki Shi Nakahara Ku Kamikodanaka” is recorded as the morpheme and associated with a code of 211-0053.However, the frequency of appearance of the string representing the address in the text is lower than the frequency of appearance of the morphemes representing place names included in the address.\",\n \"Accordingly, in the case where the morphemes are extracted in descending order of the statistical frequency of appearance during the morphological analysis, the string representing the address is much less likely to be extracted.\",\n \"For this reason, the encoded text 303 is not created from the text 301 to be encoded but the encoded text 302 is created even when the morphological analysis dictionary in FIG.\",\n \"4 is used.\",\n \"Consequently, the codes in the postal code dictionary are not used, and the compression ratio is not improved.\",\n \"During the encoding in the second pass, the postal code dictionary is searched for all of the morphemes of the result of the morphological analysis in an exact longest match manner to assign one of the codes in the postal code dictionary to the string representing the address.\",\n \"In this case, the postal code dictionary is referred the same number of times as the number of the morphemes for an exact longest match search, and this takes an enormous amount of time.\",\n \"This problem is not limited to the case where the postal code dictionary is used during the encoding in the second pass and arises also in the case where a dictionary that includes other strings other than the address is used.\",\n \"FIG.\",\n \"5 illustrates an example of a functional structure of an encoding apparatus according to the embodiment.\",\n \"An encoding apparatus 501 in FIG.\",\n \"5 includes a storage unit 511, an encoder 512, and an output unit 513.The storage unit 511 stores morpheme segment information 521 and string encoding information 522.The string encoding information 522 includes records.\",\n \"A recorded string and a code that is associated with the recorded string are recorded in each of the records.\",\n \"The morpheme segment information 521 includes records including respective morphemes and is used to segment the morphemes.\",\n \"The morpheme segment information 521 includes records including the respective front morphemes of the recorded strings of the records included in the string encoding information 522.The encoder 512 encodes a text to be encoded based on the morpheme segment information 521 and the string encoding information 522 and creates the encoded text.\",\n \"The output unit 513 outputs the encoded text.\",\n \"FIG.\",\n \"6 is a flowchart of an example of the encoding process that the encoding apparatus 501 in FIG.\",\n \"5 performs.\",\n \"The encoder 512 first analyzes the text to be encoded based on the morpheme segment information 521 (step 601).\",\n \"The encoder 512 searches the string encoding information for a string to be encoded that begins with one of the morphemes and that is included in the text to be encoded in response to identification of the one of the morphemes included in the record corresponding to one of the recorded strings among the records included in the morpheme segment information 521 (step 602).\",\n \"When the string to be encoded corresponds to the one of the recorded strings, the encoder 512 converts the string to be encoded into the code associated with the one of the recorded strings (step 603).\",\n \"The output unit 513 outputs the encoded text that includes the code after conversion (step 604).\",\n \"The encoding apparatus 501 can improve the efficiency of the two-step encoding process on the text to be encoded.\",\n \"FIG.\",\n \"7 illustrates a specific example of the encoding apparatus 501 in FIG.\",\n \"5.The encoder 512 in FIG.\",\n \"7 includes an analyzer 711, a determining unit 712, a converter 713, and a converter 714.The storage unit 511 stores a morphological analysis dictionary 721 and an address dictionary 722.The morphological analysis dictionary 721 and the address dictionary 722 correspond to the morpheme segment information 521 and the string encoding information 522 in FIG.\",\n \"5, respectively.\",\n \"FIG.\",\n \"8 illustrates an example of the morphological analysis dictionary 721.The morphological analysis dictionary 721 in FIG.\",\n \"8 includes morphemes, the parts of speech, codes, and flags.\",\n \"The parts of speech represent the parts of speech of the morphemes.\",\n \"The codes represent the codes that are associated with the respective morphemes.\",\n \"The flags are switch information representing whether the morphological analysis dictionary 721 is switched to the address dictionary 722.A flag value of a logic “1” represents that switching is performed.\",\n \"A flag value of a logic “0” represents that switching is not performed.\",\n \"According to this example, the flags corresponding to the front morphemes of the strings representing the prefectures are set to a logic “1”.For example, the part of speech of “Tokyo” is a noun, the code thereof is C1,and the flag thereof is a logic “1”.\",\n \"The part of speech of “Kawasaki” is a noun, the code thereof is C4, and the flag thereof is a logic “0”.\",\n \"FIG.\",\n \"9 illustrates an example of the address dictionary 722.The address dictionary 722 in FIG.\",\n \"9 includes strings and codes.\",\n \"The strings include the morphemes representing the address.\",\n \"The codes represent the codes that are associated with the respective strings.\",\n \"The codes may be the postal codes.\",\n \"The strings recorded in the address dictionary 722 are divided into blocks corresponding to the prefectures.\",\n \"A separator 901 represents the start position of a block for “Tokyo To”.\",\n \"A separator 902 represents the start position of a block for “Kanagawa Ken”.\",\n \"For example, the code of “Tokyo To Suginami Ku” is D1.The code of “Kanagawa Ken Kawasaki Shi Nakahara Ku” is D3.The analyzer 711 sets the switch information in the morphological analysis dictionary 721 and performs the morphological analysis on the text to be encoded based on the morphological analysis dictionary 721 to divide the text to be encoded into the morphemes.\",\n \"The determining unit 712 determines whether switching to the address dictionary 722 is performed for each morpheme created by the analyzer 711.The converter 713 converts the morphemes into the codes in the morphological analysis dictionary 721.The converter 714 converts the morphemes representing the address into the code in the address dictionary 722.FIG.\",\n \"10 is a flowchart of an example of a process of setting the switch information that the analyzer 711 performs.\",\n \"At the beginning of the process of setting the switch information, the flags of all of the morphemes in the morphological analysis dictionary 721 are set to a logic “0”.\",\n \"The analyzer 711 first performs the morphological analysis on the strings recorded in the address dictionary 722 based on the morphological analysis dictionary 721 to divide the strings into the morphemes (step 1001).\",\n \"The analyzer 711 selects the front morpheme of each string from the morphemes in the morphological analysis dictionary 721, changes the flag of the selected morpheme to a logic “1” to set the switch information (step 1002).\",\n \"The analyzer 711 may set a pointer representing the start position of each block in the address dictionary 722 as the switch information instead of the flag.\",\n \"In this case, a pointer representing the position of the separator 901 is set as the switch information for “Tokyo”, and a pointer representing the position of the separator 902 is set as the switch information for “Kanagawa”.\",\n \"FIG.\",\n \"11 is a flowchart of a specific example of the encoding process that the encoding apparatus 501 in FIG.\",\n \"7 performs.\",\n \"The analyzer 711 first performs the morphological analysis on the text to be encoded based on the morphological analysis dictionary 721 (step 1101) to extract the morphemes from the text to be encoded in order from the front (step 1102).\",\n \"Subsequently, the determining unit 712 determines whether the switch information for each morpheme extracted by the analyzer 711 in the morphological analysis dictionary 721 represents switching (step 1103).\",\n \"In the case where the switch information represents switching (step 1103, YES), the determining unit 712 searches the address dictionary 722 for a string to be encoded (morpheme group) that begins with the extracted morpheme and that is included in the text to be encoded (step 1104).\",\n \"At this time, the determining unit 712 searches the block indicated by the switch information for the string to be encoded and checks whether the string to be encoded is recorded in the block.\",\n \"The determining unit 712 can check whether the string to be encoded is recorded in the block in a manner in which the string to be encoded and each recorded string in the block are compared by using, for example, the exact longest match search.\",\n \"In the case where the string to be encoded is recorded in the address dictionary 722 (step 1104, YES), the converter 714 converts the string to be encoded into the code recorded in the address dictionary 722 (step 1105).\",\n \"The determining unit 712 checks whether the last morpheme in the text to be encoded is converted into the code (step 1106).\",\n \"In the case where the last morpheme is not converted into the code (step 1106, NO), the determining unit 712 repeatedly performs the processes at the step 1101 and later on the remaining text.\",\n \"In the case where the switch information does not represent switching (step 1103, NO), the converter 713 converts each morpheme extracted by the analyzer 711 into the code recorded in the morphological analysis dictionary 721 (step 1108).\",\n \"The encoder 512 performs the processes at the step 1106 and later.\",\n \"In the case where the string to be encoded is not recorded in the address dictionary 722 (step 1104, NO), the encoder 512 performs the processes at the step 1108 and later.\",\n \"In the case where the last morpheme is converted into the code (step 1106, YES), the output unit 513 outputs the encoded text that includes a row of the codes (step 1107).\",\n \"For example, a text to be encoded that is “Kanagawa Ken Kawasaki Shi Nakahara Ku In Live” is divided into “Kanagawa/Ken/Kawasaki/Shi/Nakahara/Ku/In/Live”.\",\n \"In the morphological analysis dictionary 721 in FIG.\",\n \"8, the flag “1” for “Kanagawa” represents switching, the block for “Kanagawa” in the address dictionary 722 in FIG.\",\n \"9 is searched for a string that begins with “Kanagawa”, and a recorded string that is “Kanagawa Ken Kawasaki Shi Nakahara Ku” is detected.\",\n \"Then, “Kanagawa/Ken/Kawasaki/Shi/Nakahara/Ku” is converted into the corresponding code D3, and the following “In” and “Live” are converted into the codes in the morphological analysis dictionary 721.In the case where the pointers are used in the morphological analysis dictionary 721 instead of the flags, the presence of a pointer corresponding to the morphemes results in determination that the switch information represents switching, and the absence of a pointer results in determination that the switch information does not represent switching.\",\n \"In this encoding process, the morphological analysis dictionary 721 is switched to the address dictionary 722 when each recorded string in the address dictionary 722 appears, and accordingly, the two-pass encoding process can be performed in a single pass.\",\n \"This enables the two-step encoding process to be speeded up and reduces calculation resources such as storage areas used for the encoding process.\",\n \"The recorded strings are divided into the blocks corresponding to the front morphemes and recorded in the address dictionary 722.This enables the subject of the search to be limited to the block corresponding to the front morpheme of the string to be encoded.\",\n \"Consequently, the blocks to be searched are limited, and the efficiency of the search process is improved.\",\n \"However, in the encoding process in FIG.\",\n \"11, whenever the switch information representing switching is detected, the string to be encoded included in the text to be encoded is compared with all of the recorded strings in the corresponding block in the address dictionary 722 by using the exact longest match search.\",\n \"For this reason, in the case where a large number of the recorded strings are included in the block, the search process at the step 1104 takes a long time.\",\n \"For example, a text to be encoded that is “Kanagawa To Go” is divided into “Kanagawa/To/Go”.\",\n \"In the morphological analysis dictionary 721 in FIG.\",\n \"8, the flag “1” for “Kanagawa” represents switching, and the address dictionary 722 is searched for a string that begins with “Kanagawa”.\",\n \"However, none of the recorded strings in the address dictionary 722 include “To”.\",\n \"For this reason, “Kanagawa” is converted into the code in the morphological analysis dictionary 721.In the case where one of the morphemes in the text to be encoded matches one of the front morphemes of the recorded strings in the address dictionary 722, but the string to be encoded that begins with the morpheme matches none of the recorded strings in the address dictionary 722 as described above, the search time wastes.\",\n \"In view of this, it is preferable that search for strings that are not recorded in the address dictionary 722 be omitted to further speed up the encoding process.\",\n \"FIG.\",\n \"12 illustrates a specific example of the encoding apparatus 501 in which search for strings that are not recorded in the address dictionary 722 is omitted.\",\n \"The structure of the encoding apparatus 501 in FIG.\",\n \"12 is the same as in the encoding apparatus 501 in FIG.\",\n \"7.The storage unit 511 stores morpheme position information 1211 in addition to the morphological analysis dictionary 721 and the address dictionary 722 and includes a working area 1212.The morpheme position information 1211 represents a recorded-string position of each morpheme included in the recorded strings in the address dictionary 722.The working area 1212 is used to determine whether a string is recorded in the address dictionary 722 by using the morpheme position information 1211 and may be a stack.\",\n \"FIG.\",\n \"13 illustrates an example of the address dictionary 722 in which the addresses of the prefectures are divided into the blocks.\",\n \"“Tokyo 1” and “Tokyo 2” represent the address block name of “Tokyo To”, and “Kanagawa 1” to “Kanagawa 5” represent the address block name of “Kanagawa Ken”.\",\n \"FIG.\",\n \"14 illustrates an example of the morpheme position information 1211 corresponding to the address dictionary 722 in FIG.\",\n \"13.The morpheme position information 1211 in FIG.\",\n \"14 includes morphemes, offsets, and filter information about the blocks of the prefectures.\",\n \"The morphemes represent the morphemes included in the recorded strings in the address dictionary 722.The offsets represent the recorded-string positions of the morphemes.\",\n \"For example, a combination of “Tokyo” and the offset “1” represents that the front morpheme of the recorded string is “Tokyo”, and a combination of “Tama” and the offset “3” represents that the third morpheme of the recorded string is “Tama”.\",\n \"The filter information is expressed by a bit string that includes bit values the number of which is equal to the number of the blocks.\",\n \"When one of the bit values for a block is a logic “1”, one of the recorded strings included in the block includes the morpheme at a position represented by the offset.\",\n \"When one of the bit values for a block is a logic “0”, all of the recorded strings included in the block do not include the morpheme at a position represented by the offset.\",\n \"For example, the bit value “1” for “Tokyo 1” corresponding to the combination of “Tokyo” and the offset “1” represents that the block for “Tokyo 1” includes a recorded string in which the front morpheme is “Tokyo”.\",\n \"The bit value “0” for “Kanagawa 1” corresponding to the combination of “Tokyo” and the offset “1” represents that the block for “Kanagawa 1” includes no recorded string in which the front morpheme is “Tokyo”.\",\n \"The bit value “1” for “Tokyo 1” corresponding to the combination of “Tama” and the offset “3” represents that the block for “Tokyo 1” includes a recorded string in which the third morpheme is “Tama”.\",\n \"The bit value “1” for “Kanagawa 3” corresponding to a combination of “Tama” and the offset “5” represents that the block for “Kanagawa 3” includes a recorded string in which the fifth morpheme is “Tama”.\",\n \"The use of the morpheme position information 1211 enables determination whether a string to be encoded is recorded in the address dictionary 722 without comparison between the string to be encoded and the recorded strings.\",\n \"In addition, in the case where the string to be encoded is recorded in the address dictionary 722, the block that includes the string to be encoded can be narrowed from the blocks corresponding to the same front morpheme.\",\n \"FIG.\",\n \"15 is a flowchart of a specific example of the encoding process that the encoding apparatus 501 in FIG.\",\n \"12 performs.\",\n \"Processes at step 1501 to step 1503 and step 1506 to step 1509 are the same as the processes at the step 1101 to the step 1103 and the step 1105 to the step 1108 in FIG.\",\n \"11.In the case where the switch information represents switching (step 1503, YES), the determining unit 712 narrows the blocks by using the morpheme position information 1211 to specify the block in the address dictionary 722 that is to be searched (step 1504).\",\n \"The determining unit 712 searches the block to be searched for the string to be encoded (step 1505).\",\n \"In the case where there is the block to be searched, the string to be encoded is recorded in the block to be searched (step 1505, YES), and accordingly, the encoder 512 performs the processes at the step 1506 and later.\",\n \"In the case where there is no block to be searched, the string to be encoded is not recorded in the address dictionary 722 (step 1505, NO), and accordingly, the encoder 512 performs the processes at the step 1509

is performed at the step 1504 in FIG.\",\n \"15.The determining unit 712 first sets a variable X, which represents an offset, to 1 (step 1601) and sets a variable W, which represents a morpheme, to the morpheme extracted at the step 1502 (step 1602).\",\n \"Subsequently, the determining unit 712 searches the morpheme position information 1211 for the bit string of the filter information corresponding to X and W (step 1603) and checks whether there is the corresponding filter information (step 1604).\",\n \"In the case where there is the corresponding filter information (step 1604,

text to be encoded (step 1602) and repeatedly performs the processes at the step 1603 and later.\",\n \"In the case where there is no corresponding filter information (step 1604, NO), the determining unit 712 refers the filter information stored in the working area 1212 to specify the blocks in which the bit values for all of the morphemes are “1” (step 1605).\",\n \"The determining unit 712 checks the number of the specified blocks (step 1606).\",\n \"In the case where the number of the specified block is 1 (step 1606, YES), the determining unit 712 decides that this block is the block to be searched (step 1607).\",\n \"In the case where the number of the specified blocks is 2 or more (step 1606, NO), the determining unit 712 determines that the string to be encoded is not recorded

healthcare information at a nursing station may be authorized to view that information.","However, other doctors and healthcare workers at the nursing station, unassociated with the patient, may not be authorized to view that same private information, or some portions of the patent's information.","Laws such as HIPAA require that the privacy of healthcare information be protected, and significant penalties can be incurred for failing to do so.","Therefore, a problem arises of restricting data to only authorized users, when such data is only obtainable or useful in a public, or semi-private
