Patent number: 5952933Abstract: A system for monitoring and controlling an area comprising a controller for controlling system operational functions and responsive to at least one remote-control transmitter. The transmitter transmits system commands to the controller in a code word having a fixed word and a hopping word therein. The fixed and hopping words are scrambled using a format word resident in the transmitter and sent to the controller only during a learn mode.Type: GrantFiled: September 15, 1997Date of Patent: September 14, 1999Inventors: Darrell E. Issa, Jerry W. Birchfield, Charles Chen
