  • Barrier movement position sensing
    Patent number: 6842112
    Abstract: Methods and apparatus for sensing barrier position in a barrier movement system are disclosed. Electrical apparatus is connected to the barrier and generates a barrier position signal representative of barrier positions which may be used by a controller to detect barrier position. The electrical apparatus can be manually adjusted to reflect a first barrier position such as a closed position. Other barrier positions can be sensed by comparing the barrier position signal to other manually adjustable position signals.
    Type: Grant
