Search system for disorientated persons outside defined home region

摘要

The search system contains a special call receiver, a central data bank with integrated alarm facility, both contained in the mobile radio network, and a locating system. The assembly can be supplemented by a special search transceiver, a higher rank service exchange, a home base station, and a detector picking-up directly when the person leaves the flat, as and if required. Light and high energy call receiver is used, differing from conventional mobile radios by exclusion of a communications with a third person. It has a cyclic activation at defined time intervals.
