Abstract: A computing platform may receive an event processing request. The computing platform may identify, by inputting first communication parameters of the event processing request into a secure communication model, communication validation information for the event processing request. The computing platform may embed, using one or more tonal bits of an audio communication corresponding to the event processing request, the first communication validation information, wherein embedding the first communication validation information generates a secure event communication. The computing platform may send the secure event communication to a recipient user device, where the recipient user device may be configured to verify the secure event communication based on the first communication validation information.

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. Also described are self-meshing networks for electrochromic windows.

Abstract: A method of controlling tint of a tintable window to account for occupant comfort in a room of a building. The tintable window is between the interior and exterior of the building. The method predicts a tint level for the tintable window at a future time based on a penetration depth of direct sunlight through the tintable window into the room at the future time and space type in the room. The method also provides instructions over a network to transition tint of the tintable window to the tint level.

Abstract: This disclosure provides connectors for smart windows. A smart window may incorporate an optically switchable pane. In one aspect, a window unit includes an insulated glass unit including an optically switchable pane. A wire assembly may be attached to the edge of the insulated glass unit and may include wires in electrical communication with electrodes of the optically switchable pane. A floating connector may be attached to a distal end of the wire assembly. The floating connector may include a flange and a nose, with two holes in the flange for affixing the floating connector to a first frame. The nose may include a terminal face that present two exposed contacts of opposite polarity.

Abstract: “Smart” controllers for windows having controllable optical transitions are described. Controllers with multiple features can sense and adapt to local environmental conditions. Controllers described herein can be integrated with a building management system (BMS) to greatly enhance the BMS's effectiveness at managing local environments in a building. The controllers may have one, two, three or more functions such as powering a smart window, determining the percent transmittance, size, and/or temperature of a smart window, providing wireless communication between the controller and a separate communication node, etc.

Abstract: Aspects of this disclosure concern controllers and control methods for applying a drive voltage to bus bars of optically switchable devices such as electrochromic devices. Such devices are often provided on windows such as architectural glass. In certain embodiments, the applied drive voltage is controlled in a manner that efficiently drives an optical transition over the entire surface of the electrochromic device. The drive voltage is controlled to account for differences in effective voltage experienced in regions between the bus bars and regions proximate the bus bars. Regions near the bus bars experience the highest effective voltage. In some cases, feedback may be used to monitor an optical transition. In these or other cases, a group of optically switchable devices may transition together over a particular duration to achieve approximately uniform tint states over time during the transition.

Abstract: This disclosure provides systems, methods, and apparatus for controlling transitions in an optically switchable device. In one aspect, a controller for a tintable window may include a processor, an input for receiving output signals from sensors, and instructions for causing the processor to determine a level of tint of the tintable window, and an output for controlling the level of tint in the tintable window. The instructions may include a relationship between the received output signals and the level of tint, with the relationship employing output signals from an exterior photosensor, an interior photosensor, an occupancy sensor, an exterior temperature sensor, and a transmissivity sensor. In some instances, the controller may receive output signals over a network and/or be interfaced with a network, and in some instances, the controller may be a standalone controller that is not interfaced with a network.

Abstract: This disclosure describes insulated glass units (IGUs) that incorporate electrochromic devices. More specifically, this disclosure focuses on different configurations available for providing an electrical connection to the interior region of an IGU. In many cases, an IGU includes two panes separated by a spacer. The spacer defines an interior region of the IGU and an exterior region of the IGU. Often, the electrochromic device positioned on the pane does not extend past the spacer, and some electrical connection must be provided to supply power from the exterior of the IGU to the electrochromic device on the interior of the IGU. In some embodiments, the spacer includes one or more holes (e.g, channels, mouse holes, other holes, etc.) through which an electrical connection (e.g., wires, busbar leads, etc.) may pass to provide power to the electrochromic device.
