Abstract
A memory positioning system for use in a remote control rear-view mirror having electric motors for adjusting the mirror's position, which position is electrically detected by linear potentiometers connected to a microprocessor that records the potentiometer-generated signals. After the signals corresponding to a pre-selected position have been recorded and the mirror adjusted to a different position, the mirror can be returned to the pre-selected position by commanding the microprocessor to operate the motors until the potentiometers detect the previously recorded positions corresponding to the recorded signals. A rib and slot on the mirror's main spherical pivot mounting provide only a limited predetermined amount of vibration-absorbing pivotal movement about an axis which intersects the plane of the mirror. The mirror also has stops which permit only a limited amount of pivotal movement about the same axis.
