  • Mitigating defects in an electrochromic device under a bus bar
    Patent number: 10520783
    Abstract: Methods are provided for fabricating electrochromic devices that mitigate formation of short circuits under a top bus bar without predetermining where top bus bars will be applied on the device. Devices fabricated using such methods may be deactivated under the top bus bar, or may include active material under the top bus bar. Methods of fabricating devices with active material under a top bus bar include depositing a modified top bus bar, fabricating self-healing layers in the electrochromic device, and modifying a top transparent conductive layer of the device prior to applying bus bars.

  • Controllers for optically-switchable devices
    Patent number: 10495939
    Abstract: This disclosure relates generally to optically-switchable devices, and more particularly, to systems, apparatus, and methods for controlling optically-switchable devices. In some implementations, an apparatus for controlling one or more optically-switchable devices includes a processing unit, a voltage regulator and a polarity switch. The processing unit can generate: a command voltage signal based on a target optical state of an optically-switchable device, and a polarity control signal. The voltage regulator can receive power at a first voltage and increase or decrease a magnitude of the first voltage based on the command voltage signal to provide a DC voltage signal at a regulated voltage. A polarity switch can receive the DC voltage signal at the regulated voltage to maintain or reverse a polarity of the DC voltage signal based on the polarity control signal.

Relevant processing involving the application may include user authentication, commissioning, adaptive control, and decisions on whether to permit an action or change requested by a user. In some embodiments, the application allows users to directly control the tint state of one or more tintable windows. In some embodiments, the application allows users to change a rule or property associated with controlling a switchable optical product.

  • Control methods and systems for networks of optically switchable windows during reduced power availability
    Patent number: 10481459
    Abstract: Certain embodiments are directed to control methods, window controllers, and uninterruptible power supplies for determining tinting instructions for optically switchable windows to reduce power usage at a site during a reduced power event. In some cases, reduced power operations are initiated by a window controller upon receipt of a trigger signal from an uninterruptible power supply sent when it detects a power loss. In some cases, tinting instructions are based on the remaining charge left on the uninterruptible power supply. In some cases, reduced power operations are delayed for a period of time.

  • ONBOARD CONTROLLER FOR MULTISTATE WINDOWS
    Publication number: 20190331978
    Abstract: 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.

  • SECURITY EVENT DETECTION WITH SMART WINDOWS
    Publication number: 20190317458
    Abstract: 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 UV 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.

The system further includes sense circuitry which is configured to determine a first window controller voltage and current for a first window controller of a plurality of window controllers. The system further includes one or more controllers which are configured to generate voltage network data based on a combination of the control panel voltage and current and the first window controller voltage and current. The system then determines an error condition in the power distribution network based on the voltage network data.

  • AUTOMATED COMMISSIONING OF CONTROLLERS IN A WINDOW NETWORK
    Publication number: 20190294018
    Abstract: In one aspect, a method, system, and/or computer program product is described for generating a graphical user interface for providing information and controlling optically switchable windows connected by a network. Windows are graphically represented using interactive smart objects that are placed within views of the graphical user interface in a manner corresponding to their physical location. In another aspect, a method, system, and/or computer program product is described for associating network IDs of optically switchable windows with the locations at which the windows are installed. Window locations are determined by analyzing received wireless transmissions that are sent from transmitters associated with each of the optically switchable windows. The determined locations are then compared with a representation of the building that provides the window locations.

  • ELECTROCHROMIC WINDOW FABRICATION METHODS
    Publication number: 20190243204
    Abstract: Methods of manufacturing electrochromic windows are described. An electrochromic device is fabricated to substantially cover a glass sheet, for example float glass, and a cutting pattern is defined based on one or more low-defectivity areas in the device from which one or more electrochromic panes are cut. Laser scribes and/or bus bars may be added prior to cutting the panes or after. Edge deletion can also be performed prior to or after cutting the electrochromic panes from the glass sheet. Insulated glass units (IGUs) are fabricated from the electrochromic panes and optionally one or more of the panes of the IGU are strengthened.
