Abstract:
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.
Abstract:
A vehicle convenience system comprising a wireless transmitter, having at least one switch therein, for communicating multiple channel commands to an expander, the expander responsive to activation of the transmitter and said expander having at least one expander output responsive to the channel commands received from the transmitter; the expander outputs being programmable to at least one user selectable mode.
Abstract:
A system for monitoring and controlling an area comprising a controller for controlling system operational functions; at least one remote control transmitter for transmitting at least one system command to said controller in a code word having a fixed word and a hopping word therein; the fixed word having an identification code for selective control of the controller, the identification code programmed therein, and a channel code for issuing high and low security commands to the controller; a hopping algorithm for modifying the hopping code of the transmitter n-times in response to n-times activation of said transmitter and for modifying the hopping word m-times within the controller upon receipt of the code word m-times from said transmitter; and, a bypass mode for bypassing the code hopping algorithm and for controlling system functions in response to the controller receiving the low security command.
Abstract:
A system for monitoring an area and sounding an alarm comprising. The system employs one or more sensors positioned about the protected area. Each sensor has one or more pulse generators generating one or more pulses each with a preassigned pulsewidth. The sensors are connected to a controller by a single wire. The controller sounds an alarm upon receipt of one or more pulses and identifies the sensor actuating the alarm by the measured pulsewidth.
