Abstract: An optical coating for a glass substrate includes an inner metal or metal alloy layer, a first pair of transparent conductive oxide or dielectric layers, and a pair of outer metal or metal alloy layers. The optical coating includes an eye-weighted transmittance of less than about 20% and an eye-weighted reflectance of less than about 30%, as measured with a D65 illuminant according to the CIE 10° Standard Observer.

Abstract: A transparency includes a first substrate having a first surface and a second surface and a second substrate having a third surface and a fourth surface. An optical coating is positioned on the fourth surface and has a refractive index real component n of greater than about 1.6 and an nk ratio greater than about 0.4, both as measured at 550 nm. The optical coating is configured to attenuate the transmission of the second substrate and not substantially affect the reflectivity of the fourth surface, as viewed from the first surface, such that the attenuation factor is less than about 50%.

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 vehicular rearview assembly with a mirror element having a curved or rounded edge on the first surface that is fully observable from the front of the assembly, a complex peripheral ring, and a user interface with switches and sensors that activate and configure pre-defined function(s) or device(s) of the assembly in response to the user input applied to the user interface. The mirror element is supported by a hybrid carrier co-molded of at least two materials, a portion of which is compressible between the housing shell and an edge of the mirror element. The peripheral ring may include multiple bands. Electrical communications between the electronic circuitry, the mirror element, and the user interface utilize connectors configured to exert a low contact force, onto the mirror element, limited in part by the strength of adhesive affixing the EC element to an element of the housing of the assembly.

Abstract: A variable transmittance electro-optic assembly includes a first partially reflective, partially transmissive substrate defining first and second surfaces. A second partially reflective, partially transmissive substrate defines a third surface and a fourth surface. The first substrate and the second substrate are configured to be held in a parallel spaced apart relationship and sealed about a perimeter of the first and second substrates. An electro-optic material is positioned between the second surface and the third surface. The electro-optic assembly includes a principle transflector having a transflector coating on at least one of first and second surfaces. Low reflectance coatings are disposed on secondary surfaces of the variable transmittance electro-optic assembly. The electro-optic assembly has a high double image characteristic defined by a ratio of a reflectance of the transflector coating to a net reflectance of at least one of the secondary surfaces, and further wherein the ratio is greater than 50.
