  • Patent number: 7884701
    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.

  • Patent number: 7688014
    Abstract: A communication protocol is employed between a movable barrier operator and an associated wall button using the traditional signaling wires connecting them. Implementing the communication protocol using the existing signaling wires also allows backward compatibility with the traditional push wall buttons that have a physical contact switch. In one embodiment, the communication protocol allows bi-directional communication between the moveable barrier operator and the wall button. The bi-directional embodiment of the protocol allows further communications, such as handshaking, signal confirmation and more advanced control between the wall unit and the barrier operator.
