  • System and method of actuating a movable barrier operator
    Patent number: 7002312
    Abstract: A system and method for actuating a moveable barrier operating system. A wireless time signal at a receiver. A time-of-day signal is supplied at the output of the receiver. The receiver is automatically reset using the wireless time signal when the time-of-day signal is different than the time represented by the wireless time signal. A moveable barrier is actuated using the time-of-day signal at the output of the receiver.

  • Digital light control
    Patent number: 4716301
    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.
