    Abstract: An imaging device enclosure for a vehicle including a housing having an image device aperture. A motor is disposed in the housing and is operably connected with a mobile wedge. The mobile wedge is operable between an extended position and a retracted position. An imaging device is slidably connected with the mobile wedge and is movable between the retracted position corresponding to the extended position of the mobile wedge and the extended position corresponding to the retracted position. A flexible boot is disposed over the image device aperture. The flexible boot defines a flexible opening. The imaging device protrudes through the flexible opening when the imaging device is in the extended position.

  • Patent number: 9910310
    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 laminated film 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.

  • Patent number: 9873167
    Abstract: A laser system comprising a laser that produces a pulsed laser beam is configured to form a laser-induced channel in a multi-layer substrate including first and second material layers. The material layers may have different refractive indices. The laser-induced channel includes a uniform distribution of self-focus damage volumes through at least a portion of the thickness of one or both of the material layers. One of the material layers may be partially transparent or non-transparent. An optical assembly of the laser system can be configured to produce uniformly distributed self-focus damage volumes at an effective focal region corresponding to the substrate thickness. The distribution of damage volumes can be tailored to include areas or peaks of high damage volume density where it is desired to ablate material.
