  • Publication number: 20070063815
    Abstract: A receiver is adapted to receive one or more wireless signals, while also being able to provide a barrier actuation signal to a barrier operator over a signaling line. The barrier operator may then be adapted to actuate a barrier in response to receiving the barrier actuation signal. The signaling line is further used to provide power from the barrier operator to the receiver. In one embodiment, the barrier operator is a garage door opener and the signaling line is coupled to the receiver and a garage door wall button. Alternatively, the receiver may replace the garage door wall button of the barrier operator.

  • Publication number: 20050206497
    Abstract: Disclosed is a system and method for proximity control of a barrier comprising a stationary wireless signal receiving device and a mobile transmitting device. The wireless signal receiving device may monitor at least one transmitting device within a predetermined coverage area and may be a radio frequency receiver or a spread spectrum receiver located near the barrier. In one embodiment, the transmitter device emits a control signal that is received by the receiving device when the transmitter is within a reception range. In one embodiment, the control signal includes transmitter identification information, directional information and position information.

  • Publication number: 20050193629
    Abstract: Disclosed are systems and methods for operating a barrier. In one embodiment, a door operator can be opened or closed by triggering either an internal device (e.g., wall button) or an external device. In one embodiment, if an obstacle is detected when the door is opening or closing, the door will either stop or swing in the reverse direction. In yet a further embodiment, the door operator is implemented using an alternating current (AC) synchronous motor.
