Abstract: An inventory control system for managing and transporting a subset of tools from a plurality of storage containers. Each of the plurality of storage containers can comprise a plurality of storage locations. Each storage location can store objects, wherein the objects can rest in a tray. Each storage location can comprise at least one image sensing device configured to capture image data of the plurality of storage locations. Each storage location can comprise a data processor configured to receive information representing captured images of the storage locations and data representing the usage or status of the objects associated with the images. The system can further comprise a portable container comprising a plurality of supplemental locations for storing the objects containers. The portable container can be configured to communicate with the plurality of storage locations and configured to reconcile objects shared between the portable container and the plurality of storage containers.

Abstract: Placemats having integrated adhesive stickers or labels constructed as a single sheet integrated placemat product. A preferred embodiment of the present invention is fabricated from a preprinted bond paper sheet having an underlying silicone coated kraft paper liner adhered to at least a portion of the rear side of the preprinted bond paper sheet. Portions of the preprinted bond paper sheet have die cuts which permit removal of preprinted designs on the integrated adhesive stickers or labels. Children or other interested patrons complete drawings on the placemats by placing or positioning the adhesive stickers or labels wherever the children or other interested patrons choose on the placemats. If desired, the adhered stickers and/or the remainder of the placemats may be further decorated or colored using various writing instruments, including pencils, pens, ink markers and crayons, to create a picture or artistic scene.

Abstract: A device is disclosed for in-water cleaning of a ship's hull. The device includes a body having inboard and outboard faces joined by a peripheral side, the faces having coaxial central apertures which are joined to form a central opening through the body, in which is mounted a hydraulic motor-driven propeller. The propeller maintains the device in contact with the hull during cleaning. There are detachable wheel modules recessed into the body to propel the device along the hull and a hydraulic motor-driven steering wheel to steer the device. Hydraulically driven cleaners are mounted on the inboard face to clean the hull. There is also a light recessed into the peripheral side to provide illumination to the hull. The device may also include an adjustable buoyancy chamber mounted on the body to provide sufficient buoyancy to the device to enable the device to effectively clean the hull at the waterline.

Abstract: A mirror collector having a generally parabolic surface terminating near the vertex in a circular or cylindrical curve, an evacuated cylindrical heat entrapment tube composed of a clear glass for energy admission and two pair of elongated heat collector tubes centrally located in the heat entrapment tube for passing an inner fluid to be heated. The two pair of heat collector tubes are constructed of copper with a selective absorption coating for receiving heat and positioned so that the mirror collector concentrates substantially all incoming energy upon the central heat collector tubes.

Abstract: A mirror collector having a generally parabolic surface terminating near the vertex in a circular or cylindrical curve, an evacuated cylindrical heat entrapment tube composed of a clear glass for energy admission and an elongated, U-shaped heat collector tube centrally located in the heat entrapment tube for passing an inner fluid to be heated. The U-shaped tube is constructed of copper with a selective absorption coating for receiving heat and positioned so that the mirror collector concentrates substantially all incoming energy upon the central heat collector tube for providing a concentration factor of about four (4).

Abstract: A mirror collector having a generally parabolic surface terminating near the vertex in a circular or cylindrical curve, a collector tube composed of a clear glass outer tube for energy admission and for passing an inner fluid, the collector being generally elliptical in nature constructed of copper with a selective absorption coating for receiving heat and positioned so that the mirror concentrates substantially all incoming energy upon the central collector tube for providing a concentration factor of about four (4).

Abstract: A mirror collector having a generally parabolic surface terminating near the vertex in a circular or cylindrical curve, a collector tube composed of a clear glass outer tube for energy admission and for passing an inner fluid, the collector being generally eliptical in nature constructed of copper with a selective absorption coating for receiving heat and positioned so that the mirror concentrates substantially all incoming energy upon the central collector tube for providing a concentration factor of about four (4).
