Retail shelf supply monitoring system
First Claim
1. A system that facilitates monitoring inventory, comprising:
- a data acquisition and transmitter circuit that is interconnected to each of a power bus, a ground bus, and a signal bus, wherein the data acquisition and transmitter circuit comprises;
a dedicated microprocessor chip that receives data input signals from a plurality of track units associated with the data acquisition and transmitter circuit over the signal bus; and
wherein the microprocessor formats data received from the plurality of track units for transmission, and passes a formatted output signal through transmitter circuitry for emission as an RF signal from an antenna; and
a receiver that receives the transmitted output signal and forwards the transmitted output signal through a router to a user device that generates at least one of an inventory report and a pilferage report;
wherein each track unit includes a pull-up resistor;
the system further comprising;
a sensor circuit coupled to each track unit; and
a sensor connected to the sensor circuit;
wherein the sensor comprises an ultrasonic transponder, sending and receiving ultrasonic waves, the actuator comprising a reflector attached to the pusher reflecting the ultrasonic waves from the transponder back to the transponder.

Abstract
An inventory shelf monitoring system includes a plurality of track systems located on at least one shelf of a retail or warehouse establishment. Each track system includes a sensor and actuator that determines the position of a product pusher. The identity and location of the product pusher, for each track system on the shelf, is sent to a data acquisition and transmitter circuit that assembles, formats, and transmits pusher position data to a central receiver. The data is then transmitted to a central processing unit in a user device that maintains data corresponding to product count, availability, and activity associated with each track unit of each shelf employing the system. Inventory control, the prevention of out-of-stock situations, and the assessment of activity indicative of theft or accident is thus monitored in real time for prompt remedial action.
