Abstract: A garage door opening system comprises a receiver which is responsive both to security codes in a first format from existing transmitters and to security codes in a new and more secure format from new transmitters. The old format comprises a synchronization character and ten code words and the new code format advantageously comprises twenty code words with a new synchronization character between the tenth and eleventh code words. The receiver determines from the received synchronization codes the type of format being received and compares the received code words with stored permitted code words of the same type. When a match occurs, an activation signal is generated.

Abstract: A door actuating system including a keypad type remote transmitter having a keypad for transmitting door open request signals generated by pressing the keys of the keypad and a stored code type remote transmitter, including a code stored in long-term storage for transmitting door open requests including the stored code. A receiver selectively opens the door responsive to the door open requests from both types of remote transmitters. The receiver includes a user settable security switch which inhibits selective door actuation responsive to door open request signals from the stored code type transmitter while permitting selective door actuation responsive to door open request signals from keypad type transmitters.

Abstract: A system for establishing a code and controlling operation of equipment. This system includes a first transmitter including a random code generator and a memory for storing the randomly generated code, as well as a transmitter for providing a radio frequency signal carrying that code. The system furthermore includes a transceiver including a receiver for the siganl generated by the first transmitter and a memory for storing the code carried by that signal. The transceiver includes a second transmitter for transmitting a radio frequency signal carrying the code. This system also includes a remote receiver unit for connection to the equipment to be controlled. This remote receiver unit has a receiver for the radio frequency signal transmitted by either the first transmitter or the transceiver and a memory for storing that random code carried by the signal.

Abstract: The present invention provides a power supply for a digital light controller which is placed in a wall box where the neutral line cannot be used. The invention uses two separate and different kinds of power supplies that are placed in series with the load and the digital light controller depends on the power supply 1 when the load is off and on the second power supply when the load is on. The supplies are alternately switched when either the remote control or a manual switch is triggered. The first power supply uses a switch that is either opened or closed to develope a voltage drop of V or 0 and the second supply uses diodes back to back to develop a voltage drop which can be stepped up and rectified to a DC voltage for powering the digital light control.
