Abstract (en)
[origin: WO9839752A1] A communication system (10) is disclosed. The system (10) comprises at least one base transmitter/receiver (11) located in a device which is either fixed at any particular location or is able to be easily transported in a mobile arrangement and a plurality of individual transmitters (12) which are able to be worn by people in the form of a wrist device, pendant or the like. The system (10) operates such that each transmitter (12) sends an encoded signal to the base transmitter/receiver (11) when activated by a person wearing the wrist device, pendant or the like or when automatically activated according to a pre-set protocol. The base transmitter/receiver (11) receives the encoded signal and thereafter provides an alarm signal indicating the source of said encoded signal.
