Intra-oral remote control. An access device for the severely disabled

A tongue-operated intra-oral remote controller of external equipment is described. It is built within the vault of an acrylic palatal plate and is intended for use by severely disabled people. It could also serve to supplement other means of control in those with lesser degrees of disability. Essentially it consists of a tongue-operated switch which completes a resonant circuit. This in turn couples electromagnetically with a coil, worn around the neck, and thence through interfacing circuitry to the external equipment. Thus the switching is remote, no leads emerge from the mouth and no batteries are required.
