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 vehicle monitoring system is configured to monitor a scanning region depicting a subject and includes a monitoring apparatus configured to capture scanning data in the scanning region depicting the subject. A feedback apparatus is configured to communicate alignment information from a portion of the vehicle to the subject. The alignment information indicates an alignment of the subject in the scanning region. A concealment apparatus is configured to conceal the scanning apparatus and selectively transmit the alignment information from the feedback apparatus. The system further includes a controller configured to activate the feedback apparatus revealing the alignment information identifying the alignment of the subject within the scanning region of the monitoring apparatus. The controller is further configured to control the scanning apparatus to capture the scanning data of the subject and monitor the subject in the scanning data.

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.

Abstract: An electro-optic assembly for use in a vehicle having a windshield is provided and includes a first arcuate substrate having a first surface with an anti-reflective coating and a second surface. A second arcuate substrate includes a third surface and a fourth surface with an anti-reflective coating. The first and second substrates are positioned such that the second and third surfaces are at least 0.1 mm apart. A seal is disposed between the first and second substrates and located substantially about a periphery of the electro-optic assembly. An electro-optic medium is positioned in a cavity defined by the first substrate, the second substrate, and the seal, the electro-optic medium including a refractive index greater than 1.2. The second surface is configured to receive and reflect incident light projected from a projector, thereby displaying information that appears to be displayed forward of the windshield.

Abstract: An electro-optic assembly is disclosed. The assembly comprises a front substrate having a first surface and a second surface substantially parallel to the first surface; a rear substrate spaced from and substantially parallel to the front substrate. The rear substrate comprises a third surface and a fourth surface substantially parallel to the third surface. The assembly further comprises an electrical contact for providing an electrical connection to an electrode in proximity to an electro-optic material and an appliqué layer. The appliqué layer is on at least a portion of the fourth surface and forms a contact-obscuring.
