Abstract: An electro-optic assembly includes a first substrate that has a first surface and a second surface opposite the first surface. A second substrate has a third surface and a fourth surface opposite the third surface. The second and third surfaces face each other to define a gap. A first electrode stack is coupled to the second surface, and a second electrode stack is coupled to the third surface. An electro-optic medium is located between the first electrode stack and the second electrode stack. At least one of the first and second electrode stacks includes a base layer, a conduction layer formed of a transparent conductive material, and a flexible conductive layer spaced from the base layer by the conduction layer. The flexible conductive layer is formed of an electrically conductive polymer.

Abstract: A reflective member having transflective and substantially opaque regions is disclosed. The transflective region may serve as a sensor opening region. When viewing the member from a first direction, the difference between a total light reflectance of the member at the substantially opaque region and at the sensor opening region is less than five percent. Additionally, when viewing the member from the first direction, the difference between a color reflectance of the member at the substantially opaque region and at the sensor opening region is less than 5 delta C* units. A sensor disposed in a second direction of the sensor opening region of the member is operable to receive light through the member at the sensor opening region. The second direction is opposite the first direction.

Abstract: An electro-optic assembly includes a front substrate that has a first surface and a second surface opposite the first surface. A second substrate has a third surface and a fourth surface opposite the third surface, the second and third surfaces face each other to define a gap. A first electrode is coupled to the second surface and a second electrode is coupled to the third surface. An electro-optic medium is in the gap. At least one of the first and second electrodes are an antireflective electrode stack including a conductive layer formed of a transparent conductive oxide, an overcoat layer in contact with the electro-optic medium and formed of a substantially transparent conductive material, an insulating layer between the conductive layer and the overcoat layer, and a base layer between the substrate and conductive layer. A conduction well contains the electro-optic medium and extends through the insulating layer.

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 electrochromic device, system using, and method for, which may pre-activate a buffer is disclosed. The electrochromic device may comprise a first substrate, a second substrate, a first electrode, a second electrode, and an electrochromic medium. The second substate may be disposed in apart relationship with the first substrate. The first and second electrodes may be associated with the first and second substrates, respectively. The electrochromic medium may be disposed between the first and second electrodes. Further, the electrochromic medium may comprise electrochromic materials and a redox buffer. Each of the electrochromic materials and the buffer may be operable between activated and deactivated states. The electrochromic device may be configured to apply a voltage to substantially pre-activate the buffer and hold the buffer in this state prior to substantially activating the electrochromic materials, thereby decreasing the response time of the electrochromic device upon activation.
