Abstract: An actuator is operated to move a mechanical device between two extreme positions of travel. While that motion is occurring, the system quantifies the amount of movement that occurs between those positions. The quantification may involve counting the number of steps of a stepper motor.

Alternatively, the number of steps can be multiplied by the time period of each step to derive the time of the movement between the extreme positions. In addition to being used to setup the actuator upon installation, this automatic ranging method can be performed periodically to compensate for effects of wear on the mechanical device.

With a short stroke lowering of the upper edge of a free-standing frameless window pane from a keyed sealing engagement on the bodywork side, a signal is generated through opening of the door and passed to an electronics evaluation unit whereupon the drive of the window lifter is activated in the lowering direction until the window pane has moved from its closed position into a predetermined partially opened position. After closing the vehicle door, as a result of the generation of a further signal, the lowered window pane is automatically closed again.

Abstract: A movable barrier or garage door operator has a barrier drive for moving the movable barrier or garage door between open and closed positions. Motion of the barrier is detected by a tachometer connected to the barrier drive or by upper and lower barrier travel limit switches. A test is made to determine if the barrier has been commanded to be in a closed state and to determine if a preselected time interval has elapsed following closure of the barrier. When both of those conditions are present and the door is moved upward without authorization an alarm signal is generated and can signal the barrier drive to apply a closing force. The timer prevents the barrier from being closed on a person or obstacle during normal operation and prevents injury. An obstacle detector also prevents unwanted closure on an obstacle.
