    Abstract: The present invention relates to a device for generating light signals, in particular traffic lights. The device according to the invention contains a housing with at least one opening, which is closed by a plate, the absorption of which can be controlled electrically, there being located in the interior of the housing behind the opening a diffuser element, which reflects incident light through the plate. Preferred switched states of the plate are either black (absorption over the entire spectral region of visible light) and colored transparent (slight absorption in specific spectral regions) or transparent (no absorption over the entire spectral region of visible light). The device according to the invention is used to generate light signals by virtue of the fact that the ambient light strikes the plate and, depending on switched state, is absorbed entirely, partially or not at all by the plate.

The exterior rear-view mirrors are repositioned with only a single motor working with a rotary cam to scan all possible mirror positions. The single-motor mechanism increases the reliability of the mirror system. The single motor accomplishes both the directional alignment and the day/night reflectivity adjustment of the mirror by use of a cam which has positions for all predicted view positions, with two reflectivity positions for each view. This invention works equally well with flat wedge mirrors and wide-angle convex wedge mirrors.

  • Patent number: 5523846
    Abstract: An apparatus for inspecting the surface condition of an object comprises a light source, an optical element for directing irradiating light from the light source to an object and for converging the light reflected by the surface of the object at its back focal plane to form an image behind the back focal plane, and an observing apparatus for observing the image. An aperture stop is arranged at or near the back focal plane to cut off a scattered component of the reflected light. A half mirror having two planes forming a predetermined micro angle each other deflects the reflected light from the optical path of the irradiating light.

  • Patent number: 5521760
    Abstract: A safety-enhanced, inside rearview mirror assembly for vehicles of the type adapted for movement between day and night positions to reduce reflected glare is disclosed. The assembly includes an energy/impact absorbing plate selected to have predetermined thickness, stiffness, cracking/permanent deformation resistance, and galvanic action passivity positioned between the glass mirror element and the day/night actuator within the mirror case. The plate absorbs the actuator impact energy should the day/night actuator be caused to impact the rear of the glass mirror element when the front of the inside rearview mirror assembly is contacted by an air bag during deployment in an accident and substantially reduces damaging protrusion of glass shards which otherwise could puncture and impair proper operation of the air bag. The plate may be spaced from the rear of the mirror element, or adhered to the mirror element preferably with a flexible, resilient adhesive laminate which doubles as an anti-scatter layer.

  • Patent number: 5481395
    Abstract: Prismatic variable reflectance mirrors are provided. In the mirrors of the invention, transmittance of reflected light is varied by thermochromic, electrochromic, photochromic or electro-optic means and the reduction in transmittance, which is required to eliminate perceptible reflection of an object to the eyes of an observer, is reduced by disposing the plane of the highly reflective surface of the mirror at an angle with respect to the plane of the surface through which light from the object enters the mirror.

  • Patent number: 5450246
    Abstract: A remotely controllable single/triple reflection glare-deflecting vehicle mirror provides remote control directional adjustment to an appropriate view, and also provides for easy and reversible toggling between single-reflection viewing and triple-reflection viewing. The mirror view adjustment is by remote control cables, selectively manually powered or powered by small linear motors. This view adjustment is maintained even during periods when glare conditions require that the wedge mirror be moved to anti-glare position, which is also done by remote control. The motor-powered version permits easy toggling from anti-glare triple-reflectivity to glare-susceptible single-reflectivity or back, by a tap switch. The manual-powered version permits easy toggling from anti-glare triple-reflectivity to glare-susceptible single-reflectivity or back, by a simple in-out motion of a glare control knob on the joystick used for view adjustment.

  • Patent number: 5233466
    Abstract: An optical device with an improved efficiency in the transmission of light through the device is disclosed. The device having an optical element in a block shape which is made up of a first plane on which incident light is presented at a predetermined incidence angle. The incident light is transmitted through the first plane and is reflected off of another plane which is oriented at a predetermined angle with respect to a plane perpendicular to the first plane. The reflected light is next totally transmitted through an exit plane situated parallel to the first plane. The incidence angle is predetermined so that the angle at which the light is finally transmitted with respect to the exit plane is a polarization angle satisfying Brewster's rule. Therefore, at the exit plane, the light is totally transmitted and thus none of the light is reflected, resulting in a greatly improved degree of efficiency in the transmission of light through the device.
