referring to fig1 , there is provided a weight scale generally represented by reference numeral 10 . weight scale 10 includes an upper platform or weight supporting surface 12 , a base 14 adapted to receive the platform , a display screen 16 preferably visible through the platform , and a plurality of load detection cells or sensors 18 ( shown in phantom ) positioned between the platform and the base . the cells 18 are mounted between the platform 12 and the base 14 in such a way that the load of the user &# 39 ; s weight on the platform will be transmitted directly to the cells , as is generally known in the art . the cells 18 may be of the type generally known in the art , which generally include a deflectable member ( not shown ) through which electric current is passed . when the deflectable member flexes under load applied to the platform 12 , it resistance properties are altered , and the change is monitored by measuring current flow . this is translated into a weight reading displayed to the user on the display screen 16 . each load cell 18 is preferably a strain gauge . such strain gauges are known in the art . in the preferred embodiment , there are four load cells that are applied one to each corner of the upper platform 12 thereby forming a generally rectangular pattern . the upper platform or surface 12 is made of any material that permits any weight thereon to be directly transmitted to the cells 18 . the upper platform 12 can be made of plastic , metal , glass or other suitable material that can hold the weight of the user without breaking . preferably , the upper surface 12 is made of plastic . the base 14 is made of any material . preferably , the base 14 is made of a material that protects the cells 18 from moisture or other undesired environmental effects that could adversely affect the performance of the cells . accordingly , the cells 18 are preferably made of ceramic or plastic . the scale 10 has a plurality of feet ( not shown ). preferably , each foot is positioned in a corner of the scale 10 . each load cell 18 is located directly above a different foot . each foot is movable relative to the upper platform 12 . fig2 shows a schematic diagram of a balance control system 20 for the weight scale 10 according to a preferred embodiment of the present invention . the balance control system 20 shows four load detections cells 18 . a computer controller 21 of the type generally known , communicates with the cells 18 to process load signals from each cell , compare the signals from each cell , and provide an output signal that results from the comparison of each load signal , to the display screen 16 that indicates to the user whether or not the user &# 39 ; s weight is evenly distributed . in the preferred embodiment shown in fig1 , the load detection cells 18 are arranged in a uniform or evenly spaced , square configuration about the platform 12 such that if a user stands so that his / her center of gravity is in the center of the platform , and thus the center of the load detection cells , the load caused by the user &# 39 ; s weight will be equally distributed and supported by each of the four load detection cells 18 so that the scale 10 will have equal load or weight distribution . it is understood that any number of cells 18 may be used , including only one cell . the cells 18 may be positioned in any pattern between the platform 12 and the base 14 . preferably , the cells 18 are positioned in a symmetrically pattern about the geometry or configuration of the platform 12 ( and base 14 ) so that it is easier to measure an unequal distribution on the platform . various types of display including one or more audible signals may be used to indicate to the user whether or not a state of equal weight distribution , or balance , is present . in the preferred embodiment shown in fig2 , a balance display 22 may be included in or separate from the display screen 16 . however , the balance display 22 is operatively connected to the display screen 16 and , thus , a computer controller 21 , so that the balance display communicates with the computer controller . in an alternative embodiment , the computer controller 21 can be operatively directly connected to the balance display 22 . the balance display 22 may include a central light or diamond 26 and an array of lights 24 . preferably , the array of lights 24 is arranged symmetrically about the central light . when the user stands on the platform 12 , the lights on the balance display 22 light up in an array indicative of the user &# 39 ; s position with respect to the center of gravity . for example , if the user &# 39 ; s weight is centered with respect to the four cells 18 , only the central light 26 will be lit . if the user is leaning or standing too much to the right , both lights 24 to the right hand side of the central light 26 will light up . as the user leans or stands more to the left , only the single light directly to the right of the central light 26 will light up , thus indicating that the user &# 39 ; s weight is shifted more toward the center . when the user finally shifts his weight to the center , only the central light 26 is lit . in a preferred embodiment , arrows are used as the indicators to show that weight needs to be shifted to , for example , the right and to the top of scale 10 . a shifting weight in the direction of the arrows until only the center light or diamond 26 lights , thus indicates the ideal balance for actuate and repeated weight measurement . thus , the indications of the balance display 22 is achieved by the cells sending a signal or communicating to the controller 21 that in turn sends one or more signals that result in displays of indicated movement or shifting to the balance display . accordingly , the cells 18 are preferably in a symmetrical or balanced ( equally spaced apart pattern ) pattern about the configuration of platform 12 to more precisely detect each variation of weight distribution . different balance indicators can be used in place of the precise embodiment described above . for instance , a different array of lights can be used , and the lighting or un - lighting sequences can be reversed depending on preference . another way of indicating balance is to provide an audible signal that signals when the user &# 39 ; s weight is centered , when it is not , and / or to which direction the user should re - position to achieve balance . operation of the above - described preferred embodiment will now be described . initially , when the scale 10 is at rest , the scale is not powered . when the user desires to use the scale 10 , the user merely taps the platform 12 . tapping the platform 12 loads the cells 18 and sends a communication to the controller 21 to initiate power - on switch 28 of the type generally known , which activates a power source 30 , such as a battery - powered pack . alternatively , a manually activated power - on switch ( not shown ) may be provided for hand manipulation or toe - touch manipulation . after the scale 10 is powered on , the scale performs a self - zeroing routine as may be known in various existing scales . the self - zeroing routine generally signals to the controller 21 that in the instant condition , the weight output on the display screen 16 is zero . the self - zeroing operation is disclosed in a u . s . application that has been filed on dec . 2 , 2003 by the applicant of the present invention . this application is incorporated herein by reference . once the scale 10 has self - zeroed , the scale is now ready for the user to stand on the scale . the user then steps onto the scale 10 . the balance display 22 responds to the position of the user &# 39 ; s center of gravity by lighting up accordingly , as described above , prompting the user to re - position or shift until the central light 26 illuminates . optionally , the controller 21 may be programmed to not display the user &# 39 ; s weight , thus displaying a blank screen or remaining at “ 0 ”, until the controller has indicated that the user &# 39 ; s weight is centered . in lieu of , or in combination with , the visual signal , an audible signal may be produced by an audible output generator 32 that indicates relative position of the center of gravity and / or a balanced condition . when the user &# 39 ; s weight is sufficiently centered with respect to the load detection cells 18 , the balance display 22 will indicate the balanced condition . a signal indicating that balance is achieved will prompt the controller 21 to activate the display screen 16 to display the user &# 39 ; s weight in pounds or kilograms . when the user steps off of the scale 10 , the controller 21 activates a time - out sequence to power - off the scale after a predetermined period . when the scale 10 is tapped again , the operational procedure repeats . the scale 10 may be provided with additional features such as a display clock and calendar , a radio and / or audible signaling device , and programmable sounds . while the preferred embodiment has been herein described , it is understood that various modifications can be made without departing from the scope of the present invention .
