A system for selectively detecting the presence of one or more objects in proximity to a person. The system includes one or more 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 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. The child units are comprised of a battery incorporated with child unit circuitry in a conventional battery configuration. The battery/child unit assembly is configured to allow the child unit to be incorporated into any existing electronic device without requiring modification to the existing electronic device.
