MOTION COMPENSATED LIGHT-EMITTING APPARATUS
First Claim
1. A light-emitting apparatus comprising:
- a light beam generator that emits a light beam;
a device that produces a first signal indicating motion of the generator;
an integrator that integrates the first signal to produce a second signal indicating movement of the light beam generator; and
a light diverting device mounted to an electronically adjustable cantilever;
wherein the second signal is applied to the cantilever so that the light beam projects substantially in a particular direction.

Abstract
A light-emitting apparatus, for enabling a beam of light to be projected on a desired target located a distance away to project the beam on the desired target without any or substantially any undesired movement. The apparatus may include a housing, a light generating device located within the housing and operable to generate a beam of light, a sensing device or devices for sensing an undesired action of the housing, a control circuit operable to provide a control signal corresponding to the sensed undesired action, and a drive device operable to counter act all or at least some of the undesired action of said housing in accordance with said control signal. The sensing device or devices may be one or more gyroscopes, accelerometers or other such devices.
