(d) a single motor (9) operationally connected to said angular adjustment means to move said cam;
(e) loading means (4) to positively load said mirror (1) such that said cam (5) remains in contact with said cam driver set (7, 10); and
(f) control means (33) for control of said motor to cause movement for both view adjustment and reflectivity adjustment.

Abstract
This single-actuator-and-cam, remotely adjustable, exterior vehicle rear-view mirror provides the driver with glare-free viewing toward the rear of the vehicle, by switching between a high-reflectivity position and a low-reflectivity position at the same view adjustment. The exterior rear-view mirrors are repositioned with only a single motor working with a rotary cam to scan all possible mirror positions. The single-motor mechanism increases the reliability of the mirror system. The single motor accomplishes both the directional alignment and the day/night reflectivity adjustment of the mirror by use of a cam which has positions for all predicted view positions, with two reflectivity positions for each view. This invention works equally well with flat wedge mirrors and wide-angle convex wedge mirrors. Since each position is unique, each directional/reflectivity position can be assigned a set of digital coordinates which can be stored for each vehicle driver and each glare condition, for an initial setting which can be easily, or even automatically, adjusted for changes as the driver desires. Customizing features include manual and vehicle driver identification controlled override, start-up reset, and glare threshold setting.
