Abstract: A combination hitch for allowing a towed vehicle to be fastened to a tow vehicle. The combination hitch includes a base for being attached to the bed of the tow vehicle, the base including a ball hitch member located substantially over the centerline of the rear axle of the tow vehicle. The combination hitch also includes a superstructure movable between a first position attached to the base and second position attached to the base. The superstructure has a pin box hitch member located substantially directly over the ball hitch member and the centerline of the rear axle of the tow vehicle when the superstructure is in the first position and not located substantially directly over the ball hitch member and the centerline of the rear axle of the tow vehicle when the superstructure is in the second position.

Abstract: A mounting apparatus for mounting an accessory to a pickup truck having a chassis, and having a bed attached to the chassis. The mounting apparatus includes a frame assembly for receiving the accessory; and bed pad structure for attachment to the chassis of the truck and for selectively attaching the frame assembly to the chassis of the truck with a portion of the bed pad structure positioned within the bed of the truck in a position in which the bed pad structure will not encumber the bed of the truck when the frame assembly is not attached to the chassis of the truck.

Abstract: The present apparatus makes use of a novel mineral identification system to not only identify the desired minerals and estimate a percent of mineralization, but also locate their presence on the mining face in an x, y coordinate manner in order to guide the mining operation of the associated robot mining apparatus. This is accomplished through the use of a camera and video monitor system which picks up the light returned from the mining face as illuminated by the light source. Therefore, on a pixel by pixel basis the camera identifies the light intensity returned from the mining face. In order to obtain the unique light signature of the desired minerals, a plurality of narrow band light filters is used to screen the light reflected from the mining face prior to its being focussed on the video camera.
