WIRELESS ITEM LOSS PREVENTION SYSTEM

摘要

An item loss prevention system for protecting from the loss of items from a user, and more specifically to an electronic device utilizing a wireless connection between a remote unit attached to an item, such as a set of one or more keys, and a host or belt unit attached to the user, to prevent the loss of the item. The system includes magnetic sensors between the item and the belt, which are Hall type magnetic sensors, coupled with an accelerometer. With the additional input from the accelerometer, an alarm activates when the item, such as a key, is separated at a distance from the belt or host unit. Additionally, the key unit can attach to an unpairing station to re-set the remote unite for re-pairing to another host unit.

主权项

1. An item loss prevention system comprising:
a host unit that receives a remote unit, the remote unit attachable to an item, the host unit receivable onto a user; and a remote magnetic sensor on the remote unit and a host magnetic sensor on the host unit, the host magnetic sensor and the remote magnetic sensor independently monitor a presence or an absence of the remote unit from a direct contact with the host unit; an accelerometer in the remote unit, the accelerometer for detecting a triggering movement of the remote unit; and the host magnetic sensor initiates an alarm in the host magnetic unit when the host magnetic sensor detects the absence of the remote unit, the remote unit the remote magnetic sensor detects the absence of the host unit and the accelerometer detects a triggering movement of the remote unit.
