    Patent number: 7024819
    Abstract: A system includes a transmitter, a receiver, and a processor. The processor detects a trigger event. In response to the trigger event, the transmitter transmits a detection signal. If the receiver receives a reflected detection signal, the processor determines that a door is in a first position. Additionally, if the receiver receives a reflected detection signal, the processor signals an opener to move the door to a second position.
