  • Publication number: 20240053650
    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.

  • Publication number: 20230266631
    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.

  • Patent number: 11467462
    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.

  • Patent number: 10300842
    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.
