Abstract:

A wire guidance system for a materials handling vehicle, such as a turret stockpicker, detects an alternating signal carried by a buried wire. Two sets of four sensors each are carried at either end of the vehicle. These sensors define regions, and a procedure is provided to determine in which region the wire is located. The distance and angle of the vehicle is determined by reference to the distance measurements of each sensor set, as calculated by a microcomputer. A self testing circuit is provided to insure proper operation of the sensors and associated circuitry.

Abstract:

A barrier assembly for a motor vehicle having a shift lever and a kit for assembling the barrier assembly are disclosed. The barrier assembly has a retainer, a lever plate, seals and spacers. The retainer has a retainer aperture extending from a first surface to a second surface. The lever plate is moveable and has a lever opening extending from a first face to a second face. A gliding surface allows the lever plate to move in a planar motion parallel to the retainer while supported on the retainer. A first seal is located on the first face of the lever plate proximal to the lever opening. A second seal is located on the first face of the lever plate distal to the lever opening. Spacers project from the retainer distal to the retainer aperture.
