    Abstract: An imaging apparatus comprises a first light source configured to project a first illumination onto a vehicle occupant and a second light source configured to project a second illumination onto the vehicle occupant. The system further comprises an imager comprising a pixel array. A lens apparatus comprises a first lens comprising a first field of view and a second lens comprising a second field of view. At least one shutter is selectively controlled to transmit the first illumination from the first lens to the pixel array. The at least one shutter is further controlled to selectively transmit the second illumination from the second lens to the pixel array. The imager is configured to process the first illumination in the first field of view and the second illumination in the second field of view.

    Abstract: An illumination system is provided that includes a light source configured to emit a first handedness polarization of light onto a body, the first handedness polarization of light having at least one of a circular and an elliptical polarization. The body reflects a second handedness polarization of light. An optical filter is configured to at least one of absorb and reflect the second handedness polarization of light and transmit the first handedness polarization of light.

    Abstract: An electro-optic system where an electrical potential is changed and/or regulated to achieve a desired potential applied to an electro-optic medium. The electro-optic system comprises an electro-optic medium disposed in a chamber defined in part by two electrodes. A power source is connected to the two electrodes and thereby operable to apply an electrical potential to the electrochromic medium across the two electrodes. A voltmeter is operable to measure an electrical potential between two points within the chamber. Additionally, a controller is connected to the voltmeter and the power source and is operable to regulate the electrical potential applied by the power source based, at least in part, on the electrical potential measured between the two points within the chamber by the voltmeter.

    Abstract: An electro-optic device is provided that includes a first substrate having an inner surface and an outer surface; a first electrode provided at the inner surface of the first substrate; a second substrate having an inner surface and an outer surface, wherein the inner surface of the second substrate faces the inner surface of the first substrate; a second electrode provided at the inner surface of the second substrate; and an electro-optic medium provided between the inner surfaces of the first and second substrates. The first electrode includes a metal mesh formed from metal tracings and having open areas between the metal tracings; and a first transparent conductive coating electrically coupled to the metal mesh and extending at least between the metal tracings so as to extend across the open areas.
