摘要： Two embodiments of a low profile weight sensor for a weight sensing system for monitoring article input and removal from article storage apparatus comprises a plate or I-shaped bar support member having first and second sections, an integrally formed linkage system for connecting the first and second sections such that the sections are substantially coplanar in an unloaded state, and are relatively displaceable with respect to each other in response to a weight load applied to one of the sections; and a magnetic transducer mounted on surfaces extending in the thickness direction of the plate/bar member for producing an electrical output signal responsive to relative displacement of the first and second sections. The article input and removal monitoring system also comprises self calibrating apparatus comprising circuitry for measuring the stability of weight measurements obtained from the weight sensors and producing a limit value, circuitry responsive to the weight sensing circuitry for signalling an operator and automatically taking first and second test measurements to obtain a calibration weight value, and circuitry for comparing the calibration weight value with a predetermined multiple of the limit value and signalling an invalid calibration if the calibration weight value is less than the predetermined multiple of the limit value.

摘要： The anti-theft product rack continuously monitors the weight of the rack including individual product units. When a weight deviation is detected, it is characterized as either a disturbance or as the removal of one or more product units. An alarm is sounded if the rack is continuously disturbed for a programmable number of continuous weight sensing cycles, or if a programmable number of disturbances occur during a programmable period of time. In addition, an alarm is sounded if the number of product units detected as being removed at one time exceeds a programmable limit. Finally, if the number of detected product units removed exceeds a programmable number during a programmable period of time, an alarm is sounded. The product display rack presents no physical barriers to product removal and requires no intervention of sales personnel for product removal. Thus, the present invention presents an aesthetically pleasing product rack while providing a high degree of protection against shoplifting or employee theft.
摘要翻译：防盗产品架连续监控机架的重量，包括各个产品单元。当检测到重量偏差时，其被表征为干扰或作为一个或多个产品单元的移除。如果机架连续干扰可编程数量的连续重量感测周期，或者在可编程时间段内发生可编程数量的干扰，则会发出报警。此外，如果一次检测到的产品单元数量超过可编程限制，则会发出警报。最后，如果在可编程时间段内删除的检测到的产品单元的数量超过可编程的数量，则会发出警报。产品展示架对产品拆卸没有物理障碍，不需要销售人员进行产品拆卸干预。因此，本发明提供了美观的产品架，同时为商店盗窃或员工盗窃提供了高度的保护。

摘要： A loss-in-weight gravimetric feeding system is disclosed which includes a prefeeder for receiving and discharging material and at least first and second feeders for receiving material from the prefeeder and discharging the received material to a common collector. The system includes a device for alternately diverting material discharged from the prefeeder to the first and second feeders, circuits for generating a first and second weight signal representative of the weight of material in the first and second feeders respectively, and structure for generating a reference signal representative of a desired mass flow rate of material from a feeder. The system further includes a circuit for alternately comparing the reference signal to the first and second weight signals in synchronism with the diverting device for controlling each of the feeders based on the comparison between the reference signal and the weight signal associated with the feeder.

摘要： A volumetric screw feeder is interchangeably convertible from a twin screw feeder to a single screw feeder without modification of the gearing or drive means. The change from twin screw feeder to single screw feeder is made by interchanging the screws and the feeder hopper. Moreover, the drive shafts for all of the screws are brought out through a unitary seal.

摘要： A digital weigh feeder includes a conveyor belt for transporting material thereon. The conveyor belt has an average tare weight. A digital weight transmitter provides at least first and second outputs having first and second frequencies respectively. The ratio of the first and second frequencies is indicative of the weight of material on the belt. A weight processor digitally computes a scaled ratio of the first and second frequencies. An auto tare circuit digitally computes the average tare weight of the conveyor belt. The computed average tare weight is substracted from the computed scaled ratio of the first and second frequencies to obtain a reading of the actual weight of material on the belt.
