Abstract: An illumination assembly configured to emit diffuse light through an indicator is disclosed. The assembly comprises a substrate having an applique disposed thereon. The applique forms an opening configured to transmit light through the substrate. The assembly further comprises a light source in connection with a circuit and configured to emit light through the shape. A diffusing layer is applied to a surface of the assembly between the circuit and the substrate. The diffusing layer comprises a resin material configured to cure in response to exposure to ultraviolet light or heat. The diffusing layer further comprises a filler material comprising a plurality of beaded structures configured to diffuse light from the light source.

Abstract: An electro-optic element includes a first substrate that has a first surface and a second surface. A second substrate has a third surface and a fourth surface, the second substrate is disposed in a spaced apart relationship with the first substrate such that the second and third surfaces face one another. A first electrode is associated with the second surface and a second electrode is associated with the third surface. An electrochromic medium is disposed between the first and second electrodes. An outer seal is disposed between the first and second substrates in a peripheral manner to contain the electrochromic medium. The outer seal is substantially uniform and defines a completely closed loop.

Abstract: An electro-optic assembly includes a first substrate and a second substrate that is disposed in a substantially parallel spaced apart relationship with the first substrate. A first conductive layer is disposed on the first substrate, and a second conductive layer is disposed on the second substrate. A cathodic electro-optic film is in contact with the second conductive layer and includes a cathodic species. An anodic electro-optic film is in contact with the first conductive layer. The anodic electro-optic film includes a plurality of anodic species mixed at a molar ratio that is configured to generally maintain an a* value and a b* value of the electro-optic assembly both staying between −8 and 8 between a high-end transmission state and a fully darkened state caused by an applied voltage range. An electrolyte medium is disposed between the cathodic and anodic electro-optic films.

Abstract: An electro-optic assembly includes a first substrate that has a first surface and a second surface that is opposite the first surface. A second substrate has a third surface and a fourth surface that is opposite the third surface. The first and second substrates are disposed in a parallel and spaced apart relationship so as to define a cavity therebetween. The second and third surfaces face each other. A seal extends between the first and second substrates. An electro-optic medium is located in the cavity and is retained by the seal. A port is at least partially defined by a port reduction member that is located between the first substrate and the second substrate.

Abstract: An electro-optic apparatus configured to adjust in transmittance in response to a control input comprises a first web substrate and a second web substrate. Each of the web substrates form a plurality of perimeter edges. A first edge is in connection with a first electrical terminal connecting in connection with a first electrode. A second edge opposing the first edge is in connection with a second electrical terminal in connection with a second electrode. A third edge and an opposing fourth edge comprise a barrier seal in a first configuration in connection with an exterior surface of each of the first web substrate and the second web substrate. The barrier seal encapsulates the electro-optic medium between an interior surface of each of the first web substrate and the second web substrate.
