    Abstract: An improved device switchable between reflective and display states comprising an optical element and a display element. The optical element comprising a liquid crystal medium disposed between first and second substrates. The optical element may further comprise a first electrode, a second electrode, an absorptive polarizer, and a reflective polarizer. The first electrode and the absorptive polarizer may be disposed in a first direction relative the liquid crystal medium. Similarly, the second electrode and the reflective polarizer may be disposed in a second direction relative the liquid crystal medium. The second direction is opposite the first direction. In some embodiments, one or more of the absorptive and reflective polarizers may be further disposed between the first and second substrates. The display may be disposed in the first direction relative the optical element. Additionally, the device may further comprise a housing. In some embodiments, the housing may not have a bezel.

    Abstract: A user monitoring apparatus for identifying a user of a vehicle includes a scanning apparatus configured to capture identifying information comprising a facial feature of the user in a field of view. A panel comprises a display portion. The apparatus further includes a feedback apparatus disposed behind the panel and configured to communicate alignment information visually indicating an alignment of the facial feature within the field of view of the scanning apparatus. The feedback apparatus includes at least one emitter configured to emit an alignment emission through an optical element thereby illuminating the alignment information on the display portion.

    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.

    IPC: G02F1/163

    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 assembly includes a first substrate and a second substrate. A primary seal is disposed between the first substrate and the second substrate. The primary seal, the first substrate, and the second substrate define an interior cavity. A fill port extends through the primary seal. A secondary seal is disposed proximate a side of the primary seal. The primary seal and the secondary seal define a channel. A sealing plug is disposed within the channel.
