Wireless item loss prevention system
First Claim
1. An item loss prevention system comprising:
- a host unit configured to receive a remote unit that is attachable to an item, and configured to be 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 configured to monitor, independently, 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 configured to detect a triggering movement of the remote unit; and
the host magnetic sensor configured to initiate an alarm in the host magnetic unit in response to the host magnetic sensor detecting the absence of the remote unit, the remote magnetic sensor detecting the absence of the host unit, and the accelerometer detecting a triggering movement of the remote unit.

Abstract
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.
