Abstract: An apparatus capable of adapting a vehicle for use in either of a dump truck mode or a spreader truck mode includes a dump body unit and a removable hopper. The dump body unit has a main frame pivotally interconnected with a dump body. The main frame attaches to the vehicle and supports the dump body. The dump body has a substantially flat bed with a lengthwise channel containing an embedded conveyor. In dump truck mode, the conveyor is covered and materials may be loaded into and dumped from the dump body. In spreader truck mode, the conveyor is uncovered and the hopper is attached to the dump body so that an aperture at the hopper's base is aligned over the conveyor. Gravity-fed materials may then be conveyed along the body to an attached spreader for dispersion.

Abstract: A retrofit recessed compact fluorescent lamp (CFL) system that delivers quality aesthetics, glare control, and high efficiency light output. The system comprises a reflector unit adapted to be installed into an existing light fixture to provide an improved environment for distribution of light from a CFL. The system is compatible with a range of existing light fixture heights and styles.

Abstract: A combined sensing and barrier element is provided. This sensing element is most useful as a flexible diaphragm which is also described herein. The flexible diaphragm has a resilient elastomeric body and a sensing element having at least one conductive component and at least two nonconductive components such that the conductive component is positioned between the nonconductive components. A change in electrical resistance is recorded by an electrical monitoring device that is electrically connected to the conductive component. By observing changes in the resistance that deviate from a predetermined norm, significant wear of a diaphragm can be determined prior to its failure.
