Integrated communication/environmental controller system for the physically disabled.

A wireless integrated communication/environmental controller system (ICECS) is described, which offers total communication as well as environmental control for the disabled person. The system is flexible and simple enough to be used from the wheelchair by patients with spinal cord injuries. The system has three parts: the mobile unit, the base unit, and a set of remote-control receiver modules. The mobile unit and the base unit are linked together by radio, while the base unit and the remote receiver modules communicate over a power line carrier. The telephone mode allows telephone calls to be placed and received. Different electrical devices are controlled by the environmental control mode. The intercom mode permits two-way communication with an attendant or the nursing station. The modes can be switched simply by pressing a button on the mobile unit. Sixteen soft-touch switches arranged in a 4 X 4 matrix allow operation by hand or mouthstick.
