Abstract

Official abstract text for this publication.

A merchandise sensor for protecting an item of merchandise displayed on a merchandise display security device from theft includes sensor electronics and a sensor element operably coupled to the sensor electronics. The sensor element provides an output value in an initial stable state before an interaction state and in a subsequent stable state following the interaction state. The sensor electronics compares the output value of the sensor element in the subsequent stable state and the output value of the sensor element in the initial stable state to determine whether a change in the output value indicates an alarm condition. In the event that the output value of the sensor element in the subsequent stable state is not within a predetermined tolerance bandwidth of the output value of the sensor element in the initial stable state, the sensor electronics activates an alarm in response to the alarm condition.

First claim

Opening claim text (preview).

That which is claimed is: 1. A merchandise sensor for a merchandise display security device, the merchandise sensor comprising: sensor electronics; and a sensor element operably coupled to the sensor electronics, the sensor element providing an output value in at least an initial stable state and a subsequent stable state following an interaction state; wherein the sensor electronics compares the output value of the sensor element in the initial stable state and the output val…
