1. A barrier movement operator comprising:
- a motor for connection to a barrier to move the barrier between open and closed positions;
a controller for controlling the energization of the motor, the controller comprising a routine to energize the motor to move the barrier toward the closed position when the barrier has been at the open position for a predetermined period of time;
a timer for identifying the passage of the predetermined period of time; and
inhibiting apparatus for controlling the timer to inhibit the controller from energizing the motor in response to the passage of the predetermined period of time.

10. A barrier movement operator comprising:
-
a motor for moving a barrier between open and closed positions when energized; a controller for selectively energizing the motor to move the barrier from the open position toward the closed position when the barrier has been in the open position for a predetermined period of time and for stopping movement of the barrier at a predetermined mid-travel position between the open and closed positions when the barrier is moving because the barrier was at the open position for the pre-determined period of time. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
