摘要： Pulse counting circuit for measuring devices such as scales and the like wherein pulses are produced by motion of the measuring device and fed to a memory element. The memory element produces a second set of pulses which are compared in phase with the original pulses. The phase difference information and pulse count information are used to produce addition and subtraction instruction signals which signals are in turn used to produce a count confirming signal which is fed to the memory element to effect coordination of the original count stored therein with the count confirming signal.

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 updown counter and utilizing the most significant counter bit to invert the counter outputs upon a transition through actual zero.

摘要： A weighing scale includes an optoelectronic system having apparatus for generating a moire fringe pattern and for detecting the moving of the pattern in accordance with scale tare deflection. One of a pair of ruled parallel grating sets is fixed with respect to the scale frame while the other is mounted for movement with the tare and close to and in a plane parallel with the fixed set. When a beam of light is projected through both grating sets in a transmissive mode towards a photodetector array the grating interference modulates the light beam into parallel moire fringes. Upon placement of a load on the scale, deflection of the tare results in movement of successive fringes across the photodetectors resulting in the sequential generation of weight indicative signals. The photodetectors are arrayed on and secured to a movable carrier which is adjustably positionable so that the effective spacings between the photodetectors corresponds to the spacings and proper phase angle required between said fringes.

摘要： A parallelogram linkage transmits the displacement of the weighing platform to a bridging arm from which the movable member of a precision displacement measuring device is suspended. This movable member is guided in a linear path in a fixed member in which adjustable screws are provided on each side of the movable member to reduce the play of the movable member in its linear path to a minimum, without introducing any appreciable amount of friction. The movable and fixed members each carry a grating and a photoelectric detector produces pulses in response to relative movement of the gratings which are counted and displayed electronically.

摘要： A computing scale system is provided for particular utility in connection with a point-of-sale merchandising terminal. The system may include a plurality of scales, each interconnected with a checkout counter and each associated with its own display unit. The display units each have electro-optic displays for displaying weight, price per unit weight and total value. The weight as measured by the scale is transmitted to the display unit for storage and display together with storage and display of price per unit weight information as entered by the display unit keyboard. Associated with one of the display units is a computing unit, which computes total price information for all display units on a time sharing basis. The computing unit generates display unit addresses at each of the display units, and the display units in turn respond with status information. So long as a display unit is in condition for servicing by the computing unit, the computing unit continues servicing that display. When a total value computation has been completed, then that total value is transmitted, together with the appropriate display unit address, to the display unit being serviced. If at any time during servicing, a display unit responds with improper status information, then the computing unit enters a program abort loop and begins servicing another display unit.
