    • This invention is directed to a novel, portable, self-powered laser alignment device which can simultaneously generate plumb, square and level laser reference points. The laser alignment device is comprised of a main body that is pendulously suspended from a unit housing. The main body is adapted to house a plurality of orthogonally oriented laser diodes that, when energized, produce a plurality of orthogonal output beams to allow the operator to easily mark plumb, square and level reference points. The laser alignment device is self-leveling, which eliminates the time consuming calibration previously required for instrument setup. The movement of the main body is dampened by use of a magnetic dampening system that is comprised of a non-magnetic metallic plate, which is passed through a permanent magnetic field. The housing of the laser alignment device contains the main body, the laser diodes, the dampening system and a power supply to energize the diodes.
    • 本发明涉及一种新颖的便携式自供电激光对准装置,其可以同时产生铅垂,平方和等级激光参考点。 激光对准装置包括从单元壳体垂下悬挂的主体。 主体适于容纳多个正交取向的激光二极管,当被激励时,其产生多个正交输出光束,以允许操作者容易地标记铅垂,平方和水平参考点。 激光对准装置是自流平的,这消除了仪器设置之前需要的耗时的校准。 主体的运动通过使用由非磁性金属板组成的磁阻系统而被衰减,该非磁性金属板通过永久磁场。 激光对准装置的壳体包含主体,激光二极管,衰减系统和用于激励二极管的电源。

    • A solid light pipe arrangement with reduced Fresnel-reflection losses includes a light pipe with a solid core comprising a polymer. An optically clear substrate has first and second sides with an anti-reflective coating on at least one side. The substrate is adhered to an end-face of the core of the light pipe by adhesive material so as to create an optically clear interface between the substrate and the end-face that passes more than about 96 percent of transmitted light. A preferred method of applying an anti-reflective coating to an end-face of a core of a solid, polymeric light pipe comprises diverting uncrosslinked polymer used for forming a light pipe core, and using the diverted polymer as adhesive material between a substrate with at least one antireflective coating and the end-face of a light pipe having the same polymeric components, in the same proportions, as the diverted polymer.

    • Luminaire with directional side-light extraction comprises a light pipe with a light-carrying core, and with a light-extraction structure along a first longitudinal side of the luminaire, confined to a radial swath of the luminaire, along the longitudinal axis of the luminaire, of substantially less than 180°. The second end has light-saving structure for directing saved light from the second end towards the first end, at redirection angles other than an excluded range of redirection angles, so long as the photon content of light at so-called alpha redirection angles is at least 10 percent of the photon content of light at so-called beta redirection angles, where the excluded range of redirection angles is defined by a mathematical formula. The light-extraction means is adjustable to accommodate angular distributions of light from various light sources.

    • The present invention relates to an expandable ring system for attaching a wheel liner to a wheel. The wheel liner has clips attached to it. Through these clips, there is sliceable placed a ring. The ring surrounds all but one of the lug nuts and lies within the offset along an outer circumference of the lug nuts. However, the ring loops into the inner circumference of proximal one of the lug nuts to lengthen or shorten the ring. The ring can then be crimped to tighten the ring against the lug nuts. A spring can also be provided to surround all of the lug nuts along the outer circumference. Prior to placing the wheel liner on the wheel, the ring can be set at the desired length so that it frictionally fits over the desired lug nuts.
    • 本发明涉及一种用于将车轮衬套附接到车轮的可膨胀环系统。 轮衬具有附接到其上的夹子。 通过这些夹子,可切片放置一个戒指。 该环围绕除了一个凸耳螺母之外的所有环,并且位于凸耳螺母的外圆周的偏移范围内。 然而,环环回到近端一个凸耳螺母的内周,以延长或缩短环。 然后可以将环圈压紧以将环紧固在凸耳螺母上。 还可以提供弹簧以围绕外周围的所有凸耳螺母。 在将轮毂放置在车轮上之前,可以将环设置在所需长度上,使其摩擦配合在期望的凸耳螺母上。
