Abstract: A vehicular exterior rearview mirror assembly for large vehicles, such as trucks, includes a reflective element, a support bracket, and an actuator mounting the reflective element to the support bracket. A mirror housing is secured to the support bracket. The electrical actuator is mounted to the support bracket by a plurality of fasteners and includes an actuator housing, which has a peripheral surface extending around the fasteners. The support bracket provides bearing contact for at least a portion of the peripheral surface of the housing to reduce the vibration and improve the stability of the mirror assembly. The electrical actuator includes a movable member which supports the reflective element for movement therewith and which extends into the actuator housing and frictionally engages the housing to minimize vibration of the movable member when it pivots.

Abstract: The specification discloses a modulated optical moisture sensor control circuit for a vehicle windshield wiper. The control system includes a first detector providing a signal indicative of moisture on the windshield and a second detector providing a reference signal indicative of system variables, such as ambient light. The control system includes improved circuitry for separating the steady-state portion of each detector signal due to ambient light from the modulated infrared IR signal. The system further includes a sensitivity adjustment accessible by the vehicle operator to alter the sensitivity of the circuit to at least one of the two variable detector signals. Additionally, the control system cooperates with a conventional off/intermittent/on wiper switch so that the wiper is responsive to the moisture sensor only when the conventional switch is in the intermittent position and a second manually actuated switch indicates preferred operation in the moisture sensor mode.
