System for tracking possessions
DCFirst Claim
1. A system for selectively detecting the presence of a plurality of objects in proximity to a person comprising:
- a plurality of child units each 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 at least one of the plurality of child units, a processor for monitoring the at least one child unit and for determining whether the at least one child unit is within a preselected range, the processor of the parent unit programmed to de-activate the second communicating device of the parent unit and the first communicating device of each of the plurality of child units when certain external communication signals are detected by the second communication device, and controls for selectively controlling the child units to be monitored.

Abstract
A system for selectively detecting the presence of a plurality of objects in proximity to a person. The system includes a plurality 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.

29. A system for selectively detecting the presence of a plurality of objects in proximity to a person comprising:
-
a plurality of child units each 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 at least one of the plurality of child units, a processor for monitoring the at least one child unit and for determining whether the at least one child unit is within a preselected range, the processor of the parent unit programmed to selectively de-activate at least one of the at least one child unit, the selective de-activation includes deactivating the locator signal of the first communication device of the at least one of the at least one child unit, and controls for selectively controlling the child units to be monitored.
