A tongue activated communications controller (10) for use by disabled or other persons to control a wide variety of devices, and which includes a dental appliance (12) fitted to the user's palate, and a keyboard (36) with a plurality of tongue activatable switches (38) for generating a signal depending upon which switch has been selected, and upon the status of a battery voltage level. The communications controller (10) includes a radio frequency transmitter (12) which uses magnetic flux linkage for transmitting the signal. The communications controller further includes a receiver (16) for converting the transmitted signal into digital form, and also includes a microprocessor based controller unit (18) for processing the received data, and for communicating with the attached devices which the user wishes to control. Data is sent from the transmitter using a fixed transmission time, digital pulse code modulation technique to achieve ultra low power consumption in the transmitter. |
