PCT No. PCT/AU85/00296 Sec. 371 Date Jul. 30, 1986 Sec. 102(e) Date Jul. 30, 1986 PCT Filed Nov. 29, 1985 PCT Pub. No. WO86/03249 PCT Pub. Date Jun. 5, 1986.A controller for controlling the movement of a member such as a sliding door driven by a motor. The door is controlled by the use of a motion detector coupled with the door. Pulses from the motion detector are counted by control circuitry, and the door is moved at a reduced speed in the region of its limits of travel. The limits are defined by the number of pulses from the motion detector equalling a predetermined value. The motor is de-energized if a stationary state of the door is detected in the low speed region, and reversed if a stationary condition is detected in the remainder of its movement. |
