Optically controllable windows and an associated window control system provide a building security platform. A window controller or other processing device can monitor for window breakage, cameras associated with windows can monitor for intruders, and transparent displays can provide alerts regarding detected activity within a building. A window control system can detect deviations from expected I/V characteristics of an optically controllable window during normal operation of the window (tint transitions, steady state conditions, etc.) and/or during application of a security-related perturbing event, and provide alerts upon their occurrence.

Certain embodiments relate to optical devices and methods of fabricating optical devices that pre-treat a sub-layer to enable selective removal of the pre-treated sub-layer and overlying layers. Other embodiments pertain to methods of fabricating an optical device that apply a sacrificial material layer.

A glazing unit is disclosed. The glazing unit can include a first pane and an active device. The active device can be coupled to the first pane. The glazing unit can also include a thermoelectric film layer between the active device and the first pane. In one embodiment, the active device is an electrochromic device.

A method of controlling a non-light emitting, variable transmission device is disclosed. The method can include receiving state information from at least one wearable device, prioritizing the received state information, sending signals from a remote management system to a first controller in response to the received prioritized state information, and changing a first transmission state of a non-light-emitting, variable transmission device to a second transmission state for the non-light-emitting, variable transmission device in response to the signals received from the first controller.

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.

Watch bands described herein include electrochromic features that provide adjustable color control based on an applied voltage to offer a variety of colors and color combinations to be displayed by a single band. The user or a control system can control, select, and/or adjust one or more colors of the watch band for visual display. Accordingly, a variety of colors can be displayed at different times without requiring different watch bands for each color or color combination. The color changing features can be used as a visual output of information from the watch to the user.

An inorganic solid-state electrochromic module containing an inorganic transparent conductive film, including a transparent substrate and a first transparent conductive layer, a first transparent metal layer, a first transparent protective layer, an inorganic electrochromic layer, an inorganic ion conductive layer, an inorganic ion storage layer, a second transparent metal layer, a second transparent protective layer, a second transparent conductive layer, a encapsulating film and a transparent front plate successively formed on the transparent substrate.

Prior electrochromic devices frequently suffer from high levels of defectivity. The defects may be manifest as pin holes or spots where the electrochromic transition is impaired. This is unacceptable for many applications such as electrochromic architectural glass. Improved electrochromic devices with low defectivity can be fabricated by depositing certain layered components of the electrochromic device in a single integrated deposition system. While these layers are being deposited and/or treated on a substrate, for example a glass window, the substrate never leaves a controlled ambient environment, for example a low pressure controlled atmosphere having very low levels of particles. These layers may be deposited using physical vapor deposition.

An electrochromic device is provided in which resistance of a bus bar is reduced. This devices includes: a pair of base members; a pair of electrodes arranged between the pair of base members; an electrochromic layer arranged between the pair of electrodes; and at least one bus bar electrically connected to one of the pair of electrodes.

The present application discloses a method for preparing an electrochromic device. The method includes placing an edge protection material on a first and second substrates, placing a first and second interlayers respectively within the edge protection material on the first and second substrates, wherein the edge protection material surrounds edges of the first and second interlayers, and interposing an electrochromic film between the first and second interlayers. The edge protection material prevents chemicals in the first and second interlayers from entering into the electrochromic film.
