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.
Claims39
A method for monitoring the position of a door, comprising:
- detecting a trigger event;
- transmitting a detection signal toward a predetermined location in response to the trigger event;
- determining whether a reflected detection signal is received;
- determining that a door is in a first position if the reflected detection signal is received;
- and
- in response to determining the door is in the first position:
- generating a warning indication;
- and
- transmitting an activation signal operable to move the door to a second position if a disable signal is not received within a predetermined period of time.

A system for detecting the position of a door, comprising:
- means for detecting a trigger event;
- means for transmitting a detection signal in response to the trigger event;
- means for checking for a reflected detection signal;
- means for determining a door is in a first position in response to receiving the reflected detection signal;
