15. Apparatus comprising:
-
a moveable body having first and second positions; a piezoelectric motor controllable to move the body from the first to the second position; an element that stores potential energy whose potential energy increases when the piezoelectric motor moves the body from the first to the second positions; and coupling apparatus controllable to decouple the motor from the body; wherein the potential energy decreases and causes the body to return to the first position when the coupling apparatus decouples the motor from the body. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)
