Abstract
A "memory" mirror system having a mirror 19 mounted within convex-shaped mirror movement boundaries, two constant speed motors 16,18 each controlling an axis of mirror movement, position feedback signals 26,28 from each motor, push button inputs 12 and an electronic controller 10, is provided with automatic mirror repositioning that drives the mirror from a start position to a "memory" position in minimum time without colliding with any mirror movement boundaries by turning ON the motor, in the direction of the target, whose movement axis is the greatest distance from the target and turning ON the other motor, in the direction of the target, if the direction toward the target is also toward the center of the mirror movement pattern (i.e., away from the nearest boundary).
