Abstract: The present teaching are related to an article comprising: a.) a horizontal rail capable of bearing loads; b.) affixed to the horizontal rail are two or more vertical support rails wherein the distance between the vertical support rails may be varied; c.) affixed to the horizontal rail are two or more carrying rails wherein the carrying rails are capable of carrying a load wherein the carrying rails may be moved to multiple positions; wherein the horizontal rail may be affixed to the vertical support rails and the carrying rails are affixed to the horizontal rail, and the vertical support rails are adapted to be affixed to a side wall of the bed of a pick-up truck.

Abstract: A bumper collision sensor can detect collision without hurting a pedestrian even if a bumper is deformed significantly. The bumper collision sensor includes a wire, a tension sensor, and a substrate. The wire has an extendable portion in a part thereof. The tension sensor is connected to one end of the wire. The substrate is mounted with the tension sensor and the wire and is attached, with plasticity, to the bumper. The tension sensor is fixed to one end of the substrate. The wire is arranged in the tension sensor along a longitudinal direction of the substrate with a stress equal to or lower than a value set in advance. The other end of the wire is fixed to the substrate.

Abstract: A truck rack includes a multi-sectioned frame assembly providing a front section and a rear section, each comprising pairs of upper and lower side rails, with the upper side rails extending significantly forward of the adjacent lower side rails. Substantially vertical uprights connect two sets of the upper and lower side rails to provide left-hand and right-hand frame units while a plurality of cross beams transversely span the two units. Provisions are made to permit vertical adjustment between the upper and lower side rails as well as to alter the length of the cross beams. Likewise, an adjustable telescopic fitting between the front and rear sections is provided.
