摘要： A floor scale for measuring body weight having a scale base, a foot platform, an electronic digital weighing system for producing a digital display indicative of the weight applied to the scale platform, and a power switch for controlling the application of power to the electronic digital display system. A weigh cycle control is provided including a kick bar mounted on the scale base at one side of the scale for movement in a generally horizontal direction and adapted to be actuated by the foot of a person before mounting the foot platform, a momentary contact type switch mounted on the scale base for actuation by the kick bar and a timer operated by the momentary contact switch for maintaining the application of power to the electronic digital weighing system for a preselected time interval sufficient for a weighing operation. The electronic digital display system can be of the type in which the weight sensor produces a series of pulses correlative with the weight applied to the foot platform of the scale and a counter for counting the pulses, and the weigh cycle control can include means responsive to operation of the momentary contact type switch means for also resetting the counter. SUBACKGROUND OF THE INVENTIONScales with various different electronic digital weighing systems have heretofore been utilized. In one type of digital weighing system, herein sometimes referred to as a direct dial position sensing system such as shown in U.S. Pat. No. 3,853,191, a coded dial is moved through a distance correlative with the weight applied to the scale and the dial is provided with a code pattern in the form of a series of concentric tracks and an associated bank of sensing components for sensing a code pattern on the dial when it comes to rest, to produce a digital signal indicative of the position of the coded dial and hence of the weight on the scale. In another type of electronic digital weighing system herein sometimes referred to as a scanning type dial position sensing system such as shown in U.S. Pat. No. 3,927,726, the weigh scale has a scale member that is rotated through an angle corresponding to the weight applied to the scale and the position of the scale member is sensed by a servo-type scanner that is driven to follow the movement of the scale member and produce a series of pulses correlative with the angular movement of the servo scanner. The pulses produced by the scanner are then counted as an indication of the position of the scale member and hence the weight applied to the scale. In still another type of electronic digital weighing system, herein sometimes referred to as an incremental type dial motion measuring system, for example as shown in U.S. Pat. Nos. 3,612,842 and 3,740,536, a scale dial is provided with a single track that cooperates with a sensor to produce a series of pulses as the scale dial is moved under the weight on the scale, and the series of pulses are counted as an indication of the applied weight. In order to accommodate oscillation and overshoot of the scale dial, an up-down counter is used and operated as an up counter in response to rotation of the dial in one direction and as a down counter in response to rotation of the dial in the opposite direction. In yet another type of electronic digital weighing system, herein sometimes referred to as an analog-digital weighing system, for example as shown in U.S. Pat. No. 3,582,619, the weight applied to the scale platform is sensed by an analog transducer such as a load cell that produces an analog electrical output signal correlative with the applied weight, and the analog electrical signal is applied through an analog to digital converter to a digital display.In some weigh scales, for example commercial scales that are used in a somewhat continuous fashion for a series of weighing operations, power for the electronic digital display system can be manually turned on and left on until the series of weighing operations is completed. However, in scales that are used for single weighing operations at a time, and then only infrequently, such as in body weight scales used in homes, it is desirable to turn the electronic digital weighing system on and off for each weighing operation. In addition, in those electronic digital weighing systems which utilize a counter, it is generally desirable to reset the counter to zero before the start of each weighing operation.The power for the electronic digital weighing system can of course be turned on and off by hand. However, hand control of power would be very inconvenient in a floor type scale since it would necessitate stooping over each time to turn the scale on and off. It has also been proposed, for example, as shown in U.S. Pat. 3,853,191 to use a switch that senses movement of the scale platform and is operated in response to the application of weight to the scale platform when the person steps on the scale. It has also been proposed, for example as shown in the aforementioned U.S. Pat. No. 3,927,726, to control the application of power of the weighing system indirectly in response to movement of the scale platform, that is in response to movement of a member that is moved by the scale platform when weight is applied.Many scales, particularly those utiliziing electronic digital weighing systems, require only a very small movement of the scale platform between its zero and fully loaded positions. In weigh control systems in which power to the electronic digital weighing system is controlled directly or indirectly in response to movement of the scale platform, it is necessary to use switches capable of being actuated with only a small travel and, moreover, it is necessary to accurately adjust the switch so as to assure that it is properly actuated between its on and off position in response to movement of the scale platform. Moreover, the power controls using switches actuated directly or indirectly in response to application of weight to the scale platform are not suitable for use in some electronic digital weighing systems, for example the incremental type dial motion measuring system since it is necessary in such incremental weighing systems to start the weighing operation immediately upon the application of weight to the scale platform.In those electronic digital weighing systems which utilize counters, it is generally desirable to reset the counters to zero before each weighing operation. Some weighing systems utilize hand operated reset buttons to reset the counters. However, such hand operated resets are objectionable on floor scales for the same reason set forth above in connection with the control of the power to the digital weighing system. It has also been proposed, for example as shown in the aforementioned U.S. Pat. No. 3,740,536 and 3,927,726 to use a reset circuit operated when the power source is actuated to reset the counters to zero.SUMMARY OF THE INVENTIONIt is the general object of the present invention to overcome the disadvantages of the prior art by providing a floor scale for measuring body weight of the type having an electronic digital weighing system and an improved weigh cycle control which enables the power for the electronic digital weighing system to be turned on for a weighing operation by the foot of a person before the person steps on the scale and conveniently in such a manner as to require only a small deviation in the foot motion usually involved in stepping on a floor scale. The weigh cycle control is also advantageously utilized to reset the counter in the electronic digital weighing system.Accordingly, the present invention provides a floor scale for measuring body weight of the type including a base and a foot platform and an electronic digital weighing system with a weight cycle control including a kick member mounted on the scale base at one side of the scale for movement in a generally horizontal direction and adapted to be actuated by the foot of a person before mounting the foot platform, a momentary contact type switch mounted on the scale base for actuation by the kick member, and a timer operated by the momentary contact type switch for maintaining the application of the power to the electronic digital weighing system for a preselected time interval sufficient for a weighing operation. A means is also provided for resetting the counter to zero in response to operation of the switch.

摘要： A line scale scanner utilizing three photoelectric cells, offset relative to one another within a space no larger than one divisional unit of the scale, to be operated as the scale moves to divide each scale unit into six increments. Each of the six increments can be obtained as the line scale moves forward or backward, providing 12 combinations from which a discriminator forms electric pulses. The pulses indicate if the increment is odd or even and if it occurred as the line scale moved forward or backward. The odd and even pulses which are provided on two different outputs of the discriminator can then be fed to counters which analyze them to determine if a system malfunction has occurred. The counters can be connected to provide the same output when the system is operating without error. Likewise, the counters can be connected to count complementary when no error has occurred. A circuit is also disclosed which provides a defect signal when a malfunction of the system occurs.

摘要： A mechanical weighing scale having mechanical parts driving a pointer rotating around a fixed disc or dial having slots or holes formed therein. The mechanical pointer operates to provide an analog display of one's weight to the user. An optical sensor system is responsive to the mechanical motion of the mechanically-rotating pointer as it passes over each of the holes or slots for determining a number of counts associated with the mechanical motion of the rotating pointer and translating the counts to a corresponding weight value for display onto a digital display.

摘要： A system for processing cyclic signal pairs generated by an optical transducer to provide an accurate measurement of the displacement of one member with respect to a reference is suitable for determining weight by measuring spring scale tare deflection. The system includes a pair of comparator Schmitt trigger circuits for shaping pulse waveform signals. The pulse signals are processed by fully clocked digital circuits including edge discriminators to generate multiple count pulses which are processed by combination logic for direction determination. Further processing includes sign determination (positive-negative) and zero identification circuits to provide up and down pulses which are filtered and fed to up/down counter stages. Counter stage information is decoded for feedback control and processing logic indication. The zero identification circuit facilitates an unambiguous zero reference indication by skipping one count at zero to provide a display sign change indication on either side of zero prior to incrementing display counts to better define true zero as an edge or line between successive displays rather than as a zone. In an alternate embodiment, zero transition indicators are provided by feeding the count pulses directly to an up/down counter and utilizing the most significant counter bit to invert the counter outputs upon a transition through actual zero.

摘要： A digital scale having an incremental measuring system is disclosed. The scale includes a source of light, a weightindicating movable grid and a stationary grid all in optical alignment, the two grids having alternately disposed transparent and nontransparent vertical surfaces, wherein the upper portions of said surfaces on the stationary grid are slightly offset from the lower portions thereof. Photoelectric means produce a series of leading and lagging electrical signals when the movable grid moves in response to a load placed on the scale, the signals from the upper portions of the stationary grid leading when the weight indicated by the movable grid is increasing, and the signals from the lower portions leading when the weight is decreasing. An electrical discriminator discerns which signals are leading, and converts them to electrical impulses which are passed to a countup-countdown counter for recording the weight. Testing circuitry, which determines when the scale is substantially still, produces electrical information for energizing digital means, connected to the counter at that time. During substantial movement of the scale, however, the testing circuit prevents the digital means from being energized, thereby assuring weight readings only when the scale is substantially still.
