A light transmitting panel assembly includes a first panel, a second panel, a frame, a gap between the first panel and the second panel, and a first active component located between the first panel and the second panel.

Disclosed are novel forms of operable and fixed windows capable of at least one or more of: producing an electrical current utilizing a transparent or semi-transparent solar collecting coating or film on a pane, and selectively changing one or more of opacity and tint of one or more electrochromatic layers in the window. Some embodiments disclose a scaffold assembly to enclose the perimeter of the substrate and one or more transparent solar cells or electrochromatic layers, or transparent solar cells and electrochromatic layers. Various structural and electrical configurations are disclosed satisfying kinematic demands of operable windows. Wired and wireless configurations of the windows are contemplated as are self-powered versions whereby the transparent solar collector or wireless power powers electrochromatic functions. Also disclosed are self-powered and self-contained glaze units with control wirelessly or from user interface controls on an indoor facing pane. Also disclosed are other smart window functions.

Onboard EC window controllers are described. The controllers are configured in close proximity to the EC window, for example, within the IGU. The controller may be part of a window assembly, which includes an IGU having one or more EC panes, and thus does not have to be matched with the EC window, and installed, in the field. The window controllers described herein have a number of advantages because they are matched to the IGU containing one or more EC devices and their proximity to the EC panes of the window overcomes a number of problems associated with conventional controller configurations. Also described are self-meshing networks for electrochromic windows.

The present invention relates to a specific multilayer composite which is suitable as a constituent of liquid-crystal devices and which contains two specific polycarbonate layers inter alia. The invention further relates to a method of producing the multilayer composite. The invention further relates to a liquid-crystal device comprising a multilayer composite according to the present invention, to a method of production thereof, and to the use thereof as structural glazing, in automotive glass, as floodlight cover, in optical filters, in shutters, in flat visual display screens, in glazed advertising devices, in dividing walls of trains, and in point-of-interest devices.

A curtain wall having a frame construction with a plurality of glass elements and optionally panels arranged at a distance from each other in a heat flow direction, wherein a multifunctional glass element is arranged on a room side behind a main heat-insulating plane of the curtain wall, wherein the position of the multifunctional glass element can be modified in a vertical direction and/or a horizontal direction and the multifunctional glass element has at least two of the functions selected from the following list: (A) anti-glare protection in a form of modifiable or switchable layers, (B) heating capacity at least in section, (C) a configuration with integrated LEDs as room lighting, (D) a configuration as an information system, particularly as a screen, at least in sections, (E) a configuration with at least one integrated camera, and (F) a configuration with at least one integrated loudspeaker.

An insulating glazing includes a first pane having on an inner-side surface a coating and two busbars for contacting the coating, a second pane, a spacer, which extends peripherally around the first and second panes, two pane contact surfaces, a glazing interior surface, and an outer surface, wherein the first and second pane rest, respectively, against a first and a second pane contact surface of the spacer, an interior, which is enclosed between the first and the second pane, an outer interpane space adjacent the outer surface, in which an outer seal is inserted, and an electrical connection element for electrically contacting the coating having an outer and an inner end, whose outer end protrudes from the outer seal. The inner end of the connection element and one busbar are electrically connected and are arranged between the spacer and the first pane outside the interior formed peripherally by the spacer.

Embodiments described include bus bars for electrochromic or other optical state changing devices. The bus bars are configured to color match and/or provide minimal optical contrast with their surrounding environment in the optical device. Such bus bars may be transparent bus bars.

A system such as a vehicle may have adjustable structures such as adjustable windows. Adjustable windows may have adjustable layers such as adjustable tint layers, adjustable reflectivity layers, and adjustable haze layers. Adjustable window layers may be incorporated into a window with one or more transparent structural layers such as a pair of glass window layers. Adjustable components such as adjustable reflectivity layers, adjustable haze layers, and adjustable tint layers may be interposed between the pair of glass window layers. Fixed partially reflective mirrors, fixed tint layers, and/or fixed haze layers may be used in place of adjustable tint, haze, and reflectivity layers and/or may be incorporated into windows in addition to adjustable tint, haze, and reflectivity layers.

Methods, systems, apparatuses, and media for controlling optical transitions are provided. In some embodiments, a method comprises: (a) applying a drive voltage having a preset magnitude to an optically switchable device to cause the optically switchable device to transition from an initial optical state toward a target optical state; (b) measuring an open circuit voltage (Voc) of the optically switchable device and/or an amount of charge that has been delivered to the optically switchable device; (c) comparing characteristics of the measured Voc and/or the amount of charge to at least one parameter indicative of a target duration of time for the optically switchable device to transition from the initial optical state to the target optical state; (d) modifying the drive voltage to have a modified magnitude, wherein the modified magnitude is determined based at least in part on the comparison; and (e) repeating (a) and (b) until the target optical state is reached.
