MULTI-MODE REMOTE CONTROL SYSTEM

摘要

A multi-mode remote control system (10) that allows an electrical load (50) such as a lamp, a fan, or the like to be operated and controlled remotely from different locations. Four distinct and independently operated system control means may be utilized to provide the desired control signal: an infrared remote control (14) such as are currently used to operate a television set; a manual control (16) such as a touch surface (16a) or a momentary SPST switch (16b); a conventional a-c wall switch (18) which could be controlling an a-c wall receptacle (54) or a power switch (20) located on the electrical load (50). The output signals produced by each of the system control means are applied to an electronics control unit (12) where the signals are processed in order to determine the amount of power applied to control the electrical load (50). Operation of any one system control means does not render any of the others inoperable.
