Abstract: A method for testing motor armature shafts is disclosed. The method includes simulating armature shaft loading conditions to test armature shaft reliability for failure. The shaft has a longitudinally extending axis, which during operation is the axis of rotation of the shaft. In the method the shaft is fixedly supported at two spaced locations a predetermined distance from one of the free ends. A normal force is rotated about the shaft's longitudinal axis. This force is exerted continuously about the circumference of the free end of the armature shaft, so that the armature shaft is continuously offset a predetermined distance from its longitudinal axis. This force is continuously applied for a predetermined number of rotations of the shaft. This simulates loading of the armature shaft in an assembled motor.

Abstract: A multi-functional apparatus for use in an automotive vehicle employing multiple tracks has a housing, a rotatable member located in the housing, an electromagnetic device and multiple tracks. The electromagnetic device may be an electric motor which operates in a unidirectional manner to oscillate a window wiper assembly. The electric motor and rotatable member then reverse rotational direction to move the wiper assembly to a park position, allowing the actuation of an intermittent motion mechanism.

Abstract: A rotatable cam of the present invention has an internal edge completely surrounding an elongated slot, a portion of which serves as a camming surface for interfacing with a cam follower. A further aspect of the present invention employs a door lock control member linearly slidable from a locked position to an unlocked position while also being pivotable between a nominal latching position and an unlatching position. In yet another aspect of the present invention, one end of the door lock control member is coupled to a liftgate door latch and the other end is coupled to a multi-functional electric motor by way of a drive transmission and a cable. In still a further aspect of the present invention, a window wiper assembly is drivably coupled to the drive transmission. A method of unlatching an automotive vehicle door is also provided.
