A signalling system to assist hard-of-hearing sports people

摘要

A system for assistance of hard-of-hearing sports people comprising one or more transmitters wherein one or more of the transmitters are integrated with a conventional audible signaling device such as a whistle and can signal by wireless on command, and one or more receivers which can be worn by players and can respond to transmissions from the transmitters by signaling to the players in a way they are able to perceive. The system can ensure full coverage of the playing area either by means of sufficient transmit power being available from the transmitter, by means of the use of repeaters around the ground, or as a mesh network where each receiver is able to retransmit any signals it receives for reception by other receivers. In addition the system can support team communication by means of separate transmitters available to coaches or managers, and potentially between the receivers themselves.
