摘要： 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.

摘要： 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.

摘要： 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.

摘要： A window control system comprises a plurality of electro-optic devices configured to control a transmittance of light through each of the plurality of zones, and at least one sensor configured to identify an intensity of light transmitted through the at least one window. A controller is in communication with the electro-optic devices and the at least one sensor. The controller is configured to independently control the transmittance of the light through each of the zones based on at least on at least one of a direction of the light and an intensity of the light detected in a passenger compartment of a vehicle.

摘要： An electro-optic assembly includes a first partially reflective, partially transmissive substrate defining a first surface and a second surface. A second partially reflective, partially transmissive substrate defines a third surface and a fourth surface. A space is defined between a first substrate and a second substrate. A seal is disposed about a perimeter of the first and second substrates. An electro-optic material is disposed between the second surface of the first substrate and the third surface of the second substrate. The electro-optic assembly is operable to change at least one of a reflectance state and a transmittance state in either a discrete or continuous manner. A transparent electrode coating is disposed between the second surface and the third surface. The transparent electrode coating includes an insulator layer, metal layer, and insulator layer (IMI) structure. The reflectance off of the transparent electrode coating is less than about 2%.

摘要： An electro-optic system is provided that includes a front element having first and second surfaces, a rear element including third and fourth surfaces, wherein the front and rear elements are sealably bonded together in a spaced-apart relationship to define a chamber, and an electro-optic medium contained in the chamber, and the electro-optic medium is adapted to be in at least a high transmittance state and a low transmittance state. The electro-optic system further includes a display device in optical communication with the electro-optic element, the display device including at least one light source and is configured to emit at least a first primary and a second primary, the first and second primaries each having a first hue (hab) when viewed through the electro-optic element in approximately the high transmittance state and a second hue (hab′) when viewed through the electro-optic element in approximately the low transmittance state, wherein a change in the first and second hues (Δhab) for both first and second primaries is less than approximately 31 degrees.
