Abstract: A device for modifying electromagnetic illumination of a reflector aperture defined by a reflector surface is mounted in front of the reflector aperture in a spaced apart relationship relative to the reflector surface. The device at least partially covers the reflector aperture and provides an illumination control means for at least partially and selectively modifying electromagnetic illumination of the reflector aperture. The device may include a membrane-like substrate that is substantially transparent to electromagnetic radiation. A supporting member may support the substrate in the spaced apart relationship relative to the reflector surface.

Abstract: This invention describes a transfer stretcher, harness and method designed to lift, transfer or support a person, more specifically a heavy weight, large size (oversize) person. Stretchers are generally used by hospitals or by rescue/emergency units to lift or carry a person from one location to another. The transfer stretcher covered by the present invention is made of a supporting canvas equipped with lifting straps and rings, a removable washable comfort cloth, and maybe used with a removable safety harness that can be used with a stretcher basket and a sling frame. The transfer stretcher can be used to move a body manually with the help of several persons, or in combination with various lifting equipment.

Abstract: An adjusting device for a tool includes a body with two ends and a fluid filled passageway, which extends between the ends, one end of the body cooperates with a work piece. An actuating member is movably connected to one end of the body, communicates with the fluid in the passageway, and has a surface, which cooperates with the work piece. Another actuating member is movably connected to the other end of the body and communicates with the fluid, and moves the fluid against the first actuating member to extend it. The fluid is locked against the first actuating member so that it retains the work piece in the body end.
