Abstract:
1. A mirror system comprising: a mirror; a moveable body operably connected to the mirror; a friction nub for controlling the motion and positioning of moveable body; at least one piezoelectric motor operably couple-able to the friction nub and to the moveable body; a motor mounting frame that holds a piezoelectric motor of the at least one piezoelectric motor; and a coupling apparatus operably connected to the motor mounting frame, the coupling apparatus controllable and configured to provide different coupling forces to the moveable body and the coupling apparatus comprises a shape memory alloy connected to a power supply, whereby the mirror is operably engaged or disengaged by controlling the temperature of the shape memory alloy with respect to a transition temperature of the alloy so that the mirror position can be adjusted by one of the at least one piezoelectric motors when the mirror is operably engaged and allowing movement of the mirror without substantial resistance when the mirror is disengaged.
