Abstract
A method of powering an obstruction detector. Power is provided to an obstruction detector when a motor is executing a first movement and is suppressed to the obstruction detector when the motor is idle and when the motor is executing a second movement. The first movement moves a movable barrier towards a closed position, and the second movement moves the barrier towards an open position.
Claims20
A method of powering an obstruction detector, comprising:
- providing power to an obstruction detector when a motor is executing a first movement;
- suppressing power to the obstruction detector when the motor is idle and when the motor is executing a second movement.
A barrier movement operator comprising:
- a movable barrier;
- a motor connected to the movable barrier;
- an obstruction detector detecting obstructions along a predetermined path;
- a processor connected to the motor and the obstruction detector;
- and
- an operation control unit connected to the processor,
- wherein the processor grants power to the obstruction detector when the motor is executing a first movement, and suppresses power to the obstruction detector when the motor is idle and when the motor is executing a second movement.
