display integrated vibration alarm ( diva ™), which refers to an embodiment of the present invention , provides an improved alarm and motoring system which can monitor oxygen levels during closed circuit mixed gas diving operations ( such as , e . g ., scuba ) and provide both visual and tactile cues to the user . among the diva ™&# 39 ; s functionality , the unit can visually display or indicate the status of a diver &# 39 ; s breathing loop oxygen content as displayed in partial pressure , as well as alert the diver if the oxygen levels in his breathing gas fall above or below thresholds that are considered dangerous . a vibrating portion of the diva ™ device allows for tactile cues to make the diver - user aware of any potentially dangerous condition of his breathing gas mixture due to the device &# 39 ; s being mounted on the diver &# 39 ; s mask or mouthpiece ( so as to allow translation of any vibrating motion caused by the vibrating portion of the device to the diver himself ). preferably , the vibrations also couple into the bone structure to stimulate the diver &# 39 ; s auditory system ( i . e ., acoustic energy coupled into the bone structure reaches and stimulates the diver &# 39 ; s cochlea ). with reference to fig1 , an illustrative embodiment of the display integrated vibration alarm ( diva ™) system of the present invention is shown . this embodiment of the diva ™ is adapted to use for closed circuit rebreather (“ ccr ”) system applications . the illustrative diva ™ 100 comprises a housing 120 , which in this embodiment , is chosen to be a stainless steel cylinder . a removable end cap 140 is disposed on a proximal end of the cylinder with a translucent or transparent cap 130 sealing the distal end of the cylinder . visible behind the cap 130 is a light emitting device 110 , which in this embodiment is implemented as a light emitting diode ( led ) device . in this illustrative embodiment , threaded portion 150 , provides a mechanism to removably secure end cap 140 to cylinder 120 . in this configuration , the system does not allow the intrusion of water such that the system is sealed from the environment . end cap 140 is a nut / cap of a swagelok fitting ( or the like ) which allows for a sealed connection of cable or conduit to diva ™ 100 . in fig2 , a cutaway view of the diva ™ 100 of fig1 is shown , to reveal the inside of the diva ™. a vibration generator 210 is provided , disposed within the housing 120 , and in this embodiment , behind ( along the longitudinal axis x of the diva ™ 100 ) the led . in the illustrative embodiment , the vibration generator is a sealed vibrating motor 210 , which , when activated , spins an eccentric weight at approximately 7 , 000 rpm . the vibration generator 210 in the diva ™ can thus provide a tactile cue to the diver , and can also provide an audible cue if the vibrations are coupled to the diver . for instance , when deployed such that it is mounted to the diver &# 39 ; s mask or mouthpiece , the diva ™ will not only transmit pulses of vibration to the diver &# 39 ; s head ( via conduction to the bone of the diver &# 39 ; s head ( e . g ., jaw and / or skull )), but also perceivable sound is created — thus the diver feels and hears his alarms at the same time , eliminating a disorienting situation occurring in know systems — that where a diver is unsure if a particular alarm is his or that of a fellow diver . the vibrating motor 210 is preferably connected to one or more sensors ( not shown ) via connection through accessway 220 . ( see , e . g ., conduit 600 shown in fig7 ) when a sensor detects a predetermined alarm condition , for e . g ., a certain amount , level and / or partial pressure of one or more components in the breathing gas , such as , oxygen , helium , nitrogen or carbon dioxide , it sends an electronic signal to the vibrating motor in the housing to activate the motor , thus alerting the diver as discussed above . the sensor triggered alarm can also be activated by sensors which detect a certain pressure or amount of gas in the tanks or containers supplying the breathing gas to the diver . in an alternative embodiment , the diver can program a ( dive ) computer or other electronic device to vary the levels of gas and / or type of gas which activates the motor — i . e ., the alarm thresholds are settable by the user . in accordance with a further implementation of the present invention , the vibration signal may be generated to have one or more signal characteristics that are modulated to convey additional information about the parameter or parameters being monitored . signal characteristics that may be modulated include , for example , frequency , intensity , duration , repetition frequency , and pattern . differently modulated signals may represent , for example , different parameters , different warning levels for a given parameter , and / or quantitative information about a given parameter . parameter levels / amounts that trigger the vibration signal , as well as the vibration signal characteristics ( e . g ., pattern , repetition frequency , etc .) may be user programmable or otherwise user settable . by way of example , two parameters that may be monitored by diva ™ are the amount of air remaining in the tank , and the partial pressure of oxygen . if the amount of air remaining in the tank becomes lower than a first predetermined amount , then a one - second pulse may be generated approximately every minute . as the air remaining in the tank drops below one or more predetermined lower levels , then a one - second pulse would be repeated at correspondingly higher repetition rates . similarly , the oxygen partial pressure level may be represented by a pattern of two one - third second vibration pulses separated by a short delay ( e . g ., one - third second ), and the repetition frequency of this pattern may be increased as the oxygen partial pressure becomes increasingly dangerous . alternatively , for example , the pattern of vibration pulses may indicate the partial pressure of oxygen , and the pattern may be repeated at fixed time intervals or at a time interval that depends on the criticality of the oxygen partial pressure level . for instance , two vibration pulses per pattern may indicate a safe level , three pulses per pattern a less safe level , etc . alternatively , the number of pulses per pattern and / or the pattern itself may be more specifically mapped to oxygen partial pressure quantities , at least over a range of oxygen partial pressure values . for instance , over the range of 0 . 4 to 0 . 8 atm , a partial pressure amount may be quantized / rounded in 0 . 2 increments and represented as a number of consecutive one - third second pulses , separated by a one - third second delay , with each pulse representing 0 . 2 atm . thus , 0 . 4 atm would be represented by two consecutive one - third second pulses . over the range of 1 . 0 to 1 . 8 atm , the partial pressure amount may be quantized / rounded in 0 . 2 increments and represented as a two - third second vibration pulse ( representing 1 . 0 ) followed by a number of consecutive one - third second pulses each representing 0 . 2 atm , with a one - third second delay between each vibration pulse in the pattern . thus , a 1 . 2 concentration would be signaled as a two - thirds of a second pulse followed by a single one - third second pulse . oxygen concentration amounts above or below this range may be signaled by a common warning , such as a continuous vibration or a continuous one - third second vibration / one - third second delay pulse train . in this way , the oxygen partial pressure quantity over the range of 0 . 4 to 1 . 8 , quantized / rounded in 0 . 2 atm increments , is conveyed to the user through the vibrations . the repetition rate of these patterns may be increased for more dangerous quantities ( i . e ., approaching hypoxic or hyperoxic levels ). as may be appreciated , in this way , the user recognizes the one - second vibration pulse as signaling the amount of air remaining in the tank , and the shorter vibration pulse pattern ( i . e ., having one - third second and possibly two - third second pulses ) as signaling the oxygen partial pressure , with the pulse / pattern repetition frequency and / or the pattern as corresponding to the amounts of these monitored parameters . while independently deployable , in the illustrative embodiment , the vibrating alarm is combined with a visual indicator , which in the illustrative case is a three color led 11 that can transmit light of three different colors , red , green , or red / green , which together yields orange . the three - color led allows conveyance of more information by a combination of colors , in contrast to a more limited array of alarms which would be available with a single color led . the led can be programmed to provide various levels of alert or other status conditions in the diver &# 39 ; s breathing gas , such as low gas levels , low tank pressure , or different concentrations or partial pressures of specific components of the breathing gas . the diva ™ can be worn by a scuba diver on their diving mask or breathing mouthpiece such that the distal end of the housing 120 , through which the led 110 is visible , is positioned so it can be viewed by the diver . the diva ™ is mounted such that the led 110 is positioned directly in the diver &# 39 ; s field of vision . the led and vibration motor can be programmed to trigger at the same threshold or their triggering can be offset or staggered . all diva ™ alarms / notifications thresholds and settings are software adjustable / settable . the diva ™ alarms include : low / high set - point out - of - range ( on / off ) fast ascent warning ( on / off ) deco stop violation warning ( on / off ) hypoxic mix alarm ( on / off ) as shown in fig3 , cap 130 is used to seal the distal end of the housing 120 . in the illustrative embodiment the cap is a mushroom - shaped , optically passive cap , which simply allows light from the led to exit the housing . in the illustrative embodiment , the cap 130 is formed as a convex lens for enhancing focusing of emissions of the led in the diver &# 39 ; s field of vision . at the distal end of the housing 120 , an o - ring 310 removably retains and seals cap 130 , which is the form of a “ mushroom ” in a fashion mated to the housing . fig4 a shows convex cap 130 of the illustrative embodiment . the cap is mushroom shaped and has a portion 420 which will sealably mate to the interior aperture formed by the cylinder of housing 120 . portion 420 optionally has a recess 430 so as to not impact led 110 , when mated . fig4 b shows the mated cap / o - ring assembly and where portion 420 will sealably mate to the housing 120 . in the illustrative embodiment , as mentioned , housing 120 can be made from stainless steel , the led 110 is a 1 . 5 v tricolor led , the vibrating motor 210 is a 1 . 5 volt dc vibrating motor , cap 130 is a transparent acrylic cap , and a watertight cable gland arrangement ( attachable through accessway 220 ) which prevents water from entering the unit during diving operations , connects either directly to a sensor in the breathing gas ; on a device storing the breathing gas , usually in a pressurized state ; and / or to electronics controlling and / or monitoring the sensors in the breathing system . in the illustrative embodiment , the diva ™ 100 is 2 . 35 inches long and the housing 120 is machined from 316 stainless steel . the diva ™ can be deployed in a number of ways , none of which are critical , although some may work better than others . in the illustrative embodiment , the diva ™ is attached to the dive surface valve dsv ( as will be explained in detail below with respect to fig5 - 7 ). in alternative embodiments , the housing may be mounted on a mouth piece that gives the diver access to the breathing gas , such that when the motor is activated , it vibrates the mouthpiece of the diver , which is received by the teeth and skeletal structure of the diver &# 39 ; s head amplifying the vibrating alarm and virtually eliminating any possibility that the alarm could not be detected by the diver . alternatively , the housing can also be mounted on a mask providing a direct alert to the diver &# 39 ; s head . in this way , in accordance with a preferred implementation of the present invention , the diver wearing the diva ™ alarm apparatus feels the tactile / vibration signal stimulating nerve endings in the skin , deep tissue , teeth , and / or skeletal bones , joints , and also hears the tactile signal , as the tactile / vibrating signal also couples into the user &# 39 ; s bone structure to stimulate the diver &# 39 ; s auditory system ( i . e ., acoustic energy coupled into the bone structure reaches and stimulates the diver &# 39 ; s cochlea ). with reference to fig5 - 7 , diva ™ 100 is mountable via a mount specific bracket . fig5 illustrates a bracket 500 for mounting the diva ™ 100 to an inspiration dsv , as the illustrative embodiment . the bracket includes : a mounting aperture 510 , through which the diva ™ is inserted and secured ; aperture 520 through which conduit to connect diva ™ 100 to a dive computer or controller ; and slot 530 for mounting to a diver contact surface . fig6 illustrates the diva ™ 100 attached to bracket 500 , with swagelok end cap 140 securing the diva ™ 100 through aperture 510 as well as securing cable 600 , routed through aperture 520 , to diva ™ 100 . fig7 shows the diva ™ 100 mounted to dsv 700 , through slot 530 , which allows some adjustment of the height of the diva ™ ( relative to the diver &# 39 ; s head ) to suit the personal preference of a diver . an illustrative embodiment of operation of an embodiment of the present invention will now be described . in this illustrative embodiment , the led indication is programmed so as to flash a different color in a specific code so that the diver is visually made aware of a particular status — e . g ., that of the oxygen concentration of the diver &# 39 ; s breathing gas . thus when , e . g ., the oxygen content of their breathing gas pass a threshold of life supportability , the led indicator will provide a visual cue to the diver . should the diver , through inattention or distraction , not notice or ignore this visual indication , the vibrating motor 210 is activated to provide the cue , thereby alerting the diver to imminent danger . the illustrative embodiment of the diva ™ 100 connects to a dive computer or display (“ hud ”) controller in a configuration with three oxygen sensors . the hud controller utilizes a pattern of flashes , red , green and orange ( a combination of the red and green side of the led flashing at once ). since the hud is designed ( in this embodiment ) for the use of three oxygen sensors , it will be appreciated that a complete sequence of flashing is comprised of a series of three patterns . the pattern of flashing is a function of the fraction of a ppo2 ( oxygen partial pressure ) for each sensor read . the led will flash orange ( both red and green at the same time ) for a ppo2 of 1 . 0 . for every point above 1 . 0 ( i . e . 1 . 1 , 1 . 2 , 1 . 3 , etc .) the green led will flash once . for every point below 1 . 0 , the red led will flash once . if the gas mixture in the loop has a ppo2 of 1 . 2 , the hud will flash two greens three times ( remember , it is responding to all three sensors ). it will look to the diver &# 39 ; s eye like this : green green — slight pause — green green — slight pause — green green — longer pause , then a repeat of the same pattern . conversely , if the gas mixture in the loop had a ppo2 of 0 . 8 ( two points below 1 . 0 ), your hud will flash two reds three times . it will look like this : the present invention has been illustrated and described with reference to particular embodiments and applications thereof . it will be readily apparent to those skilled in that art that the present invention will have applications beyond those described herein for purposes of description of the invention . for example , the present invention can be adapted for use in any environment where flexible structure formation is desired by implementing the principals taught herein . to facilitate discussion of the present invention , a preferred embodiment is assumed , however , the above -
