1. A micro-electromechanical device, comprising:
- a frame;
a moveable member movably connected to the frame such that the moveable member is capable of movement relative to the frame;
a drive system for use in moving the moveable member relative to the frame;
a braking system that inhibits movement of the moveable member relative to the frame;
a controller that controls movement of the moveable member; and
a sensor that provides a signal indicative of acceleration of the micro-electromechanical device to the controller;
wherein the controller controls the braking system based on the signal provided by the sensor.
