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.
