US Patent 6995662 Vehicle positioning apparatus

A vehicle positioning apparatus is shown and described. The positioning apparatus is adaptable for the guidance of a vehicle into a limited space, such as in the case of a boat approaching a dock, slip, or trailer. The vehicle includes two emitters, producing two images reflected to the operator of the vehicle. The emitters are spaced from each other in such a manner that the operator may determine direction, orientation, and other critical parameters of the vehicle during approach to the limited space by viewing of the reflected images. Targets may be employed to enhance the image seen by the operator.
