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: A transparent photovoltaic (TPV) integrated directly into the structure of an electrochromic (EC) device is beneficial in that it can eliminate at least one substrate and provide more uniform coloring. Integration of a transparent photovoltaic with an electrochromic device may also reduce or eliminate the need for an electrical bus on a substrate. In some embodiments, positioning the TPV internally with the EC cell may eliminate the need for additional substrate layers or a conductive layer on one side of the TPV cell. Integrating a PV cell into the EC device can additionally reduce the need for external wiring and an external power supply. Alternatively, the TPV can assist in charging a battery where the battery can be used to power the EC device when there is no sunlight available.

Abstract: A laser system and method includes control of the direction of polarization of a laser beam that forms laser-induced channels in a substrate along a process path. Control of the direction of polarization is useful while forming laser-induced channels in substrate materials having a crystalline component. An optical element, such as a waveplate, imparts the laser beam with a direction of polarization that is controllable with respect to an axis of the substrate when the substrate is supported by the system for processing. The direction of polarization is changeable and controllable with respect to the direction of the process path and/or a crystalline plane of the substrate via movement of the optical element or the substrate or both.

Abstract: A vehicular rearview assembly, includes a front substrate defining a first surface and a second surface. The front substrate being substantially transparent. The front substrate defines a shaped edge along a periphery of the first surface. A first polarizer is coupled with the second surface. An electro-optic element is coupled to the first polarizer having a first substrate defining a first element surface and a second element surface. A second substrate is spaced away from the first substrate and defines a third element surface and a fourth element surface. An electro-optic material is positioned between the first and second substrates. A second polarizer is coupled to the fourth element surface. A display is configured to emit light having a first polarization into the second polarizer. A reflective layer is positioned between the front substrate and the display is configured to reflect both the first polarization of light and a second polarization of light.
