  • Publication number: 20200407037
    Abstract: A dust cover for an aerospace window that comprises dust cover having an exterior substrate and an interior substrate in a spaced apart relationship with a substantially transparent coupling agent therebetween. The dust cover is disposed in a spaced apart relationship from an electro-optic element, defining a gap therebetween. The gap 30 mm or less, 25 mm, 20 mm, 15 mm, 10 mm, 8 mm, 7 mm, 6 mm, 5 mm, 4 mm, 3.5 mm, and/or 3 mm. The exterior substrate, the coupling agent, and the interior substrate are comprised of a combination of materials, such that the combination is substantially transparent and operable to resist breaking and maintain sufficient rigidity to prevent the electro-optic from breaking, when a force of 680 N is applied to an interior surface of the interior substrate in the direction of the electro-optic element.

  • Patent number: 10434948
    Abstract: A vehicle display mirror system is disclosed. The system comprises a display device and a reflecting polarizer. The display device is operable to display image data on a display surface as display light. The reflecting polarizer comprises a light receiving surface proximate the display surface and configured to output the display light in a first polarization from an emitting surface. The system further comprises a liquid crystal element, a polarizing element, and a controller. The controller is in communication with the liquid crystal element and configured to selectively align a liquid crystal material to pass the display light through the liquid crystal element and deactivate the liquid crystal element to adjust a received light from the first polarization to a second polarization and reflect the second polarization from the emitting surface.

  • Patent number: 10427606
    Abstract: Anisotropic film laminates for use in image-preserving reflectors such as rearview automotive mirror assemblies, and related methods of fabrication. A film may comprise an anisotropic layer such as a light-polarizing layer and other functional layers. The film having controlled water content is heated under omnidirectional pressure and vacuum to a temperature substantially equal to or above a lower limit of a glass-transition temperature range of the film so as to be laminated to a substrate. The laminate is configured as part of a mirror structure so as to increase contrast of light produced by a light source positioned behind the mirror structure and transmitted through the mirror structure towards a viewer. The mirror structure is devoid of any extended distortion and is characterized by SW and LW values less than 3, more preferably less than 2, and most preferably less than 1.
