Inventory management
First Claim
1. An inventory monitoring system which comprises:
- a plurality of merchandise detectors, each of said merchandise detectors being fitted on top of a substrate and comprising at least one elongate array of photosensors and a magnetic element configured to releasably secure the at least one elongate array of photosensors to the substrate, each photosensor of said at least one elongate array of photosensors being a reverse-biased light emitting diode (LED) that acts as a photodiode, each photosensor configured to detect a presence or absence of products based on proximity of one of the products in a predetermined merchandise position above the merchandise detector interfering with detection of environmental lighting detection by at least one photosensor of said at least one elongate array of photosensors and to emit a detect signal confirming such presence or absence, and each of said merchandise detectors including a transmitter connected to the photosensors and configured to transmit the detect signal; and
at least one gateway device with a receiver that is configured to receive the detect signals from the merchandise detectors, and a transmitter that is configured to compile a merchandise data signal from the detect signals, and to transmit said merchandise data signal.

Abstract
An inventory monitoring system (10) is provided, which includes a number of merchandise detectors (12) that each include a number of sensors that are configured to detect the presence or absence of products in a predetermined merchandise position, a position on a shelf in a retail space, and to emit a detect signal confirming such presence or absence. Each of the merchandise detectors (12) also includes a rear unit (28) with a transmitter that is connected to the sensor and that transmits the detect signal. The system (10) includes one or more gateway device (36,40) that receives the detect signals from the merchandise detectors (12) and compiles a merchandise data signal from the detect signals, and transmits it a computer (42) to be used in monitoring and managing inventory.

10. A merchandise detector which comprises:
-
a base layer; a plurality of photosensors fitted on the base layer in an elongate array, each photosensor being a reverse-biased light emitting diode (LED) that acts as a photodiode, each said photosensor being configured to detect a presence or absence of an object on one side of the base layer and to emit a detect signal confirming such presence or absence by the object interfering with detection of environmental lighting detection by said at least one of said plurality of photosensors; a magnetic element configured to releasably secure said base layer to a surface; electronic circuitry connected to the photosensors to receive the detect signals from the photosensors; and a transmitter connected to the electronic circuitry and configured to transmit the detect signals. - View Dependent Claims (11, 12, 13, 14, 15, 16)
