System for tracking possessions
First Claim
1. A system for detecting the presence of at least one object, comprising:
- at least one child unit attached to an object to be detected, the at least one child unit having a first communicating device for sending a locator signal and for receiving a control signal;
a parent unit having a second communicating device for receiving the locator signal from the at least one child unit, a processor for determining whether the at least one child unit is within a preselected range based upon the signal received from the first communicating device of the child unit, an alarm triggered by the processor when the processor determines that the at least one child unit is beyond the preselected range, and controls for controlling at least one function of the parent unit; and
a first global positioning device associated with the parent unit and a second global position device associated with the at least one child unit for providing relative global positions of the child unit and the parent unit to allow the processor to determine the distance between the parent unit and the at least one child unit.

Abstract
A system for selectively detecting the presence of a plurality of objects in proximity to a person. The system includes a plulrality of child units each having a first communicating device (such as a transceiver) for sending a locator signal and for receiving a control signal. Further, the system includes a parent unit having a second communicating device for receiving the locator signal from at least one of the plurality of child units, a processor for monitoring the at least one child unit and for determining whether the child unit is within a preselected range, at least one alarm for signaling the person when the selected child unit is outside the preselected range, and controls for selectively controlling the child units to be monitored and for controlling activation of the child units.
