Abstract: A variably transmissive electro-optic window that has an easily tunable dynamic range is disclosed. The window comprises a first substrate, a second substrate, a first electrode, a second electrode, an electro-optic medium, and at least one tuning layer. The first substrate has a first and a second surface. The first surface is in a first direction relative the second surface. The second substrate has a third and a fourth surface. The third surface is disposed in the first direction relative the fourth surface. The second substrate is disposed in a second direction opposite the first direction relative the first substrate. The second substrate is additionally disposed in a substantially parallel and spaced apart relationship with the first substrate. The first electrode is disposed in the second direction relative the first substrate. The second electrode is disposed in the first direction relative the second substrate. The electro-optic medium is disposed between the first and second electrodes. Additionally, the electro-optic medium is operable to vary a transmittance of light therethrough. Lastly, a tuning layer is substantially transparent and operable to attenuate the transmittance of visible light therethrough.

Abstract: An electro-optic element includes first and second spaced-apart transparent substrates defining respective opposite, aligned first and second edges, a first bus including a first electrode disposed along an inner surface of the first substrate adjacent the first edge and a second electrode disposed along an inner surface of the second substrate adjacent the first edge, and a second bus including a first electrode disposed along an inner surface of the first substrate adjacent the second edge and a second electrode disposed along an inner surface of the second substrate adjacent the second edge. The first bus and second bus are spaced apart along widths of the first and second substrates between the respective first and second edges. An electro-optic medium is disposed between the first and second transparent substrates, including between the first and second electrodes of the first bus and the second bus, respectively.

Abstract: An electro-optic assembly comprises a first substrate and a second substrate. The first and second substrates are disposed in a parallel and spaced apart relationship so as to define a cavity therebetween. A primary seal extends between the first and second substrates. An electro-optic medium is located in the cavity and retained in an inboard direction by the primary seal. A plurality of first spacer elements are coupled to the primary seal. A break wall is located in the inboard direction or an outboard direction from the primary seal. The break wall extends between the first and second substrates and generally along the primary seal. A plurality of second spacer elements are coupled to the break wall. A space is defined between the primary seal and the break wall in the inboard-outboard directions.

Abstract: An electro-optic element comprises a first substrate; a second substrate generally parallel to the first substrate; a first bus having a first bus segment disposed on an inner surface of the first substrate and extending along a first portion of a perimeter of the first substrate and a second bus segment disposed on an inner surface of first substrate and extending along a second portion of the perimeter of the first substrate. The second bus segment is in a spaced apart relationship with first bus segment. A second bus has a third bus segment and a fourth bus segment is disposed on the second substrate, each extending along a portion of the perimeter of the second substrate. A controller is configured to be in selective electrical communication with first and second buses and to independently control a voltage applied to each of the bus segments.

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 window comprises a first substrate; an electro-optic element generally parallel to the first substrate, the electro-optic element comprising: a second substrate; a third substrate generally parallel to the second substrate; a sealing member disposed along at least a portion of a perimeter of one of the second and third substrates and extending therebetween; and a cavity defined between the second and third substrates. The sealing member defines the sidewalls of the cavity. A first layer of film having a perimeter portion and a central portion is disposed between at least a portion of the first and second substrates, and may be coextensive with the sealing member.

Abstract: An electro-optic device includes a first electro-optic element and a second electro-optic element in series with the first electro-optic element via a common node conductively connecting the first electro-optic element to the second electro-optic element. A power supply circuitry includes a first node and a second node. The first node connects the power supply circuitry to the first electro-optic element, and the second node connects the power supply circuitry to the second electro-optic element.
