First Claim
1. An apparatus for aligning two objects, comprising:
- a scanner member, said scanner member being configured for reversible attachment to a first object, said scanner member comprising;
an enclosure;
a light source, said light source being configured for projecting an initial beam of light, said light source being configured for mounting in said enclosure;
a light sensing member, said light sensing member being configured for receiving a reflected beam of light, said light sensing member being configured for converting said reflected beam of light into electrical current in proportion to the intensity of said reflected beam of light, said light sensing member being configured for mounting in said enclosure;
a processing member, said processing member being configured for controlling said light source, said processing member being configured for receiving said electrical current and converting said electrical current into digital data, said processing member being configured for mounting in said enclosure; and
a transmitting member, said transmitting member configured for receiving and transmitting said digital data;
a target member, said target member being configured for attachment to a second object, said target member being configured for reflecting said initial beam of light received from said light source back along its angle of incidence for reception by said light sensing member; and
a display device, said display device being configured for receiving said digital data from said transmitting member, said display device being configured for interpreting said digital data and indicating relative position of said second object with respect to said first object.

Abstract
An apparatus for aligning a tow vehicle and a trailer having a scanner mounted on or near the bumper of the tow vehicle, one or more targets on or near the trailer hitch, and a display device inside the tow vehicle cabin. The scanner emits a laser beam which is scanned across the target area. The target reflects most of the laser energy back along the beam to the scanner. A photodetector in the scanner measures the reflected beam and determines distance and position of the target by accurately measuring timing of the reflected pulses. Distance and position information is conveyed to the display device, which, in turn, indicates to the driver the relative position of the tow vehicle with respect to the trailer.
