Abstract: Safety eyewear (10) having interchangeable lens(es) (28,30) is provided. To provide for interchange of the lenses (28,30) in the frame (12), upper and lower frame members (32,34) are molded from a harder, more rigid plastic while lateral temple portions (20,22), and a central nose bridge portion (18) are molded from a softer, more elastic material. The entire frame structure (12) is preferably molded as a unitary piece to form a unitary frame having rigid upper and lower frame portions (32,34) joined by flexible intermediate portions (18,20,22). In this regard, the upper and lower frame portions (32,34) can be flexed or stretched relative to each other to temporarily separate the frame portions (32,34) and open up the lens openings (24,26).

Abstract: Due to an ever growing shortage of conventional energy sources, there is an increasingly intense interest in harnessing solar energy. The instant invention is concerned with method and apparatus for the alignment of solar concentrator micro-mirrors and the maximization of the percentage of incident light that is reflected to the receiver. Novel method and apparatus are taught for operating the addressing and alignment micro-optics solar concentrator system for single-axis and two-axis tracking. Broadly this invention deals with novel concepts used for alignment in the focussing of light wherever mirrors are used for focussing such as for solar propulsion assist, illumination and projection of light, optical switching, etc. A particularly important objective is the focussing of sunlight for solar power conversion and production. The instant invention can contribute to the goal of achieving environmentally clean solar energy on a large enough scale to be competitive with conventional energy sources.

Abstract: A system for attaching safety glasses to headwear often called a “helmet” or a “hard-hat” has multiple adjustments that fit the glasses to the individual user and that allow the user to flip the glasses back and forth between in-use and removed positions. The preferred system includes a base piece that attaches to the interior or underside of the helmet, near the wearer's face at or near the junction of the helmet's bill/brim and dome. A preferred second piece receives a portion of the glasses at its distal end, and, at its proximal end, slideably connects to the base piece. The second piece may be locked at various positions relative to the base piece, to adjust, either incrementally or continuously, the distance of the glasses from the helmet. This slidable adjustment between the base piece and second piece makes it possible to adjust the glasses in a generally vertical direction, that is, generally parallel to the plane of the lenses of the glasses when being used, as best suits the particular user.

Abstract: The present invention is directed to a control system for a MEMS device, such as a MEMS mirror, that uses sliding mode analysis to accurately and predictably control the position of the mirrors in a MEMS device. The present invention also uses the capacitance of the mirror to detect the position of the mirror. In one embodiment, a MEMS mirror device mounted on a substrate is described that includes, a micro mirror that is pivotable about an axis, a first conductive layer on the mirror, a second conductive layer on the substrate, the first and second conductive layers form a first capacitor for determining the position of the mirror. The sliding mode control can be implemented using various drive mechanisms, including electrostatic drives. When used with electrostatic drives, conductive layers that create the capacitors can also be used to drive the mirror. The detection-drive system can be time multiplexed to simplify implementation and to avoid cross talk.
