Motion-compensating light-emitting apparatus

A laser pointer apparatus usable by an operator for enabling a spot of light to be projected on a desired target located a distance away from the operator, said apparatus comprising:

• a housing;
• generating means located within said housing for generating a beam of light;
• sensing means for sensing an undesired action of said housing;
• control means for providing a control signal corresponding to the sensed undesired action;
• and
• counter acting means for counter acting all or at least some of the undesired action of said housing in accordance with said control signal so that the spot is projectable on the desired target without any or substantially any undesired movement.

A light-emitting apparatus comprising:

• a light generating device which is operable to generate a beam of light;
• a sensing device operable to sense an undesired action of the generating device;
• and
• a compensating circuit operable to compensate for the sensed undesired action so that the beam of light is projectable on a target without any or substantially any undesired movement.
