Abstract:

A locator system for locating a person, animal or mobile object for use with a cellular network, the locator system including a fob containing a GSM transceiver for communication with the cellular network, a GPS unit for indicating the location of a person, animal or object being searched for, a baseband processor for controlling electronic modules in the fob and an RF beacon for transmitting strong ID signals in pulse form for indicating the direction and location of the fob. The system can operate with a call center to which communications are made by a guardian seeking assistance in finding the lost person, animal or object, which in turn communicates with the cellular network to send signals to activate the fob and which receive signals from the fob. Mobile or handheld tracking units pick up GPS and RF beacon signals to find the fob. The locator system can be used in combination with a residential locating system.

Abstract:

A system for containing a child within a defined area, for communicating with the child, and for locating the child if the child leaves the defined area is disclosed. The containment capability of the system is provided by a presently existing electronic pet containment system. The child wears a monitoring module that produces a signal that is transmitted back to a control unit in the possession of the parent, thus warning the parent if the child approaches or crosses the wire defining the boundary of the defined area. The parent can use the control unit transceiver to communicate with the child and the child can communicate with the parent using the transceiver within the monitoring module. If the child leaves the defined area, the control unit has locating capabilities that provide the parent with an indication as to the direction in which the child is moving and the distance between the child and the control unit.
