Abstract
System for positioning a reflector includes a base (112), yoke (104) and a reflector in the form of a lens mirror assembly (10). A motor (120) is mounted and remains substantially stationary with respect to rotation about a first axis while the yoke rotates about the first axis. A connecting rod (152) actuated for movement by the motor is mechanically coupled to the reflector so that movement of the connecting rod in relation to the yoke imparts rotation to the reflector about the second axis when the reflector is supported by the yoke. A mechanical drive system couples an output shaft of the motor to the connecting rod. The mechanical drive system is arranged so that it varies an angular position of the reflector at a rate which is linearly related to the rotation of the output shaft.
