Optically guided alignment system
First Claim
1. A system for aligning objects, comprising:
- (a) a first optical source capable of emitting an optical beam of a first color toward a first object; and
(b) a second optical source capable of emitting an optical beam of a second color toward said first object;
(c) wherein said first and said second optical sources are configured for attachment to a second object such that when said first colored optical beam and said second colored optical beam intersect at a target location on said first object, a light emission of a third color is produced at said target location and said objects are aligned.

Abstract
A tow hitch alignment apparatus having a pair of light sources that emit different colored light beams. The light sources are positioned such that, when the trailer hitch components are in proper position for engagement, both light beams intersect at the target location and emit a third colored light, which indicates to the driver that the tow vehicle is in the proper position for coupling with the trailer. In an alternate embodiment, the tow vehicle has a horizontal sensor plate embedded with photoelectric cells adjacent the tow ball which detects the approach of the tow hitch from the trailer. A laser emitter is placed adjacent the trailer hitch and directed at a pre-focused position. As the tow ball approaches the hitch, laser light from the emitter strikes various photoelectric cells on the sensor plate, which is in connection with a display within the driver'"'"'s compartment. The display provides information and guides the driver regarding the tow vehicle'"'"'s path towards the trailer hitch.
