Abstract: Systems and methods for determining body composition by combining dual-energy x-ray (DXA) technology with three-dimensional (3D) optical technology and/or bioimpedance technology. A multi-modality scanning system may include a dual-energy x-ray source and an x-ray detector mounted to opposing sides a c-arm and configured to scan a patient on a optically translucent table. The system may also include one or more 3D optical imaging devices to capture 3D optical images of the patient substantially concurrently with the emission of the dual energy x-rays. A bioimpedance machine may also be included in the multi-modality scanning system. Data based on the dual-energy x-rays may be combined with the data from the 3D optical images and/or the bioimpedance data to generate values of at least three compartments selected from: bone, fat tissue, lean tissue, dehydrated lean tissue, and water.

Abstract: A plurality of separable racks for stacking vertically within a sheet metal enclosure of a field barbecue apparatus. The racks permit optimum utilization of a body of still hot air within the enclosure and above the fire box of the apparatus.

Abstract: A field barbecue apparatus for preparing large quantities of food. The apparatus includes a rectangular enclosure that maintains a hot air cooking and warming environment around the food. The enclosure in cross section has a height approximately equal to its width.

Abstract: An article of apparel for shielding portions of the body from flying debris such as saw splinters, drill chips, dust, grit, and other particulate matter resulting from overhead work with a hand-held tool, includes a sleeve with an arm-fitting cuff for containing one hand of a user, a porous sleeve-section connecting with the cuff, a transparent sleeve section connected above the porous sleeve section and a loop with a downward angled handle for grasping by the other hand of a user and supporting the upper end of the sleeve against an overhead; pumping action of sawing or the like is prevented by breathing action of the porous sleeve section from blowing debris out of the sleeve, and the transparent sleeve section affords good visibility combined with shielding for the user.
