Abstract: A method of reducing drag on the underside and rear wheels of a commercial vehicle which is a drag reduction system including an airfoil designed to mount on the underside or slider assembly of a commercial vehicle that would reduce the air drag forces and improve fuel economy for the vehicle, a hydraulic system that operates to adjust the angle of the airfoil, and at least two sets of controllers, one controller that operates automatically in conjunction with the speed of the vehicle and a second controller that allows the operator to manually adjust the angle of the airfoil from within the driver's compartment. The purpose of the drag reduction system is to provide a more fuel efficient design for commercial vehicle applications, resulting in fuel cost savings for the vehicle operation.

Abstract: A tarpaulin or portable tarping system for covering loads on flatbed trailers. Said portable tarping system includes retractable tarps of various lengths, for instance, 5 ft., 10 ft., or 20 ft. lengths that are affixed to the cut-outs of the flatbed and then stretched across the load. These tarps can be placed adjacent to each other along the length of the flatbed, or placed on opposing sides of the flatbed, or placed across the width of the flatbed to ensure maximum overlap of the tarps and full coverage of the load.

Abstract: A falling freight restraint system for trailers and cargo containers that prevents freight that is leaning against door from forcing the door open and possibly falling out, which could otherwise cause injury to the person who opens the door or damage to the freight.

Abstract: This method of reducing the drag between coupled vehicles is designed to improve the aerodynamics of coupled vehicles by enclosing the gap between the coupled vehicles with a series of overlapping panels. The panels are attached to the leading vehicle and adjust along the top and sides of the trailing vehicle as the vehicle moves and turns so that while turning the gap between the leading vehicle and trailing vehicle remains enclosed.
