Abstract: A steering column for a motor vehicle includes a steering shaft, mounted rotatably about a longitudinal axis in a steering column housing, and a rotation limiter, and has a smooth and quiet construction of the rotation limiter. The rotation limiter includes two oppositely directed flat spiral springs, which are operatively arranged between a coupling part, disposed in a rotationally secure manner on the steering shaft, and the steering column housing.

Abstract: A method and device for emitting electromagnetic radiation at high power using a gallium containing substrates such as GaN, AN, InN, InGaN, AlGaN, and AlInGaN, is provided.

Abstract: Detachable wearable electronic eyeglasses and head mounted gear with a plurality of electronic functions and interchangeable electronic functions, and a wearable computer with optimal weight distribution and stretchable arms.

Abstract: A method and system of providing circularly polarized eyewear is provided. The eyewear comprises substantially rigid material configured to maintain lensing material, such as card stock or plastic. The lensing material comprises polarizing lensing material located proximate the substantially rigid material, and retarder lensing material matched to the polarizing lensing material. The retarder lensing material is positioned adjacent to the polarizing lensing material such that each eye of a user sees an intended image, and an unintended image is blocked thereby when used in conjunction with suitably polarization encoded projected images. The polarizing lensing material and retarder lensing material are fixedly maintained in association with the substantially rigid material and are configured to be provided free of lamination.

Abstract: A multi-color flat panel display of individually manufactured components operatively assembled to produce a multi-color image from a monochromatic source, the individually manufactured components include a color output assembly for converting a photon pattern produced by the monochromatic source to a corresponding electron pattern for excitation of color phosphors to display a corresponding optical image in color; and an optical collimator for preventing cross-talk between input section pixels of the monochromatic source and unassociated output section pixels of the color output assembly.
