摘要:
A system for issuing a notification responsive to the occurrence of an event affecting a monitored person. The system has a monitoring device that determines occurrence of an event related to the health or safety of the person and produces a first signal when the event occurs. A first communications device issues a second signal upon receiving the first signal and a second communications device issues a notification signal upon receiving the second signal. The notification signal is issued to one or more entities and advises that an event has occurred. The first communications device has a shorter communications range than the second communications device. Also, the second communications device operating at a higher power level or a greater signal bandwidth than the first communications device.
