Publication number: 20240053650Abstract: 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.Type: ApplicationFiled: August 14, 2023Publication date: February 15, 2024Applicant: Gentex CorporationInventors: Michael J. Dornbush, Gerald W. Redwine, Garret C. DeNolf, Stephen F. Richlich, Kevin L. Ash, Donald L. Bareman, David R. Bush

Publication number: 20230266631Abstract: 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.Type: ApplicationFiled: February 17, 2023Publication date: August 24, 2023Applicant: GENTEX CORPORATIONInventors: Garret C. DeNolf, Caleb Knust, Leroy J. Kloeppner, Punam Giri

Patent number: 11467462Abstract: 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.Type: GrantFiled: December 6, 2019Date of Patent: October 11, 2022Assignee: GENTEX CORPORATIONInventors: Garret C.
