Abstract:
A distributed device control system is provided. The system includes a plurality of windows, each window having at least one electrochromic window, a voltage or current driver for the at least one electrochromic window, and a first control system local to the window. The system includes a plurality of window controllers, each window controller configured to couple to one or more of the windows and having a second control system, for the one or more of the plurality of windows, local to the window controller. The system includes a command and communication device configured to couple to the plurality of window controllers, configured to couple to a network, and having a third control system, for the plurality of windows, wherein control of the plurality of windows is distributed across the plurality of windows, the plurality of window controllers, the command and communication device, and a portion of the network.
Abstract:
An electrochromic device, with an external power supply configured to supply a limited amount of power to the electrochromic device and a boost circuit power supply that is local to the electrochromic device and configured to supply power to the electrochromic device that is larger than the limited amount of power supplied by the external power supply is provided.
Abstract:
A cloud learning system for smart windows is provided. The system includes at least one server configured to couple via a network to a plurality of window systems, each of the plurality of window systems having at least one control system and a plurality of windows with electrochromic windows and sensors, wherein the at least one server includes at least one physical server or at least one virtual server implemented using physical computing resources. The at least one server is configured to gather first information from the plurality of window systems, and configured to gather second information from sources on the network and external to the plurality of window systems. The at least one server is configured to form at least one rule or control algorithm usable by a window system, based on the first information and the second information, and configured to download the at least one rule or control algorithm to at least one of the plurality of window systems.
Abstract:
A smart driver system for electrochromic devices is provided. The system includes at least one smart driver having one or more processors, memory and a communication module. The at least one smart driver is configurable to couple to or integrate with one or more smart windows having electrochromic devices. The at least one smart driver is configurable to input identification information from a plurality of self-identifying components of a smart window system, including the one or more smart windows, and to self-initialize or self-adjust a plurality of operating parameters for operation of the self-identifying components in accordance with the identification information.
Abstract:
A method of controlling tint for a plurality of electrochromic devices, performed by a control system, is provided. The method includes receiving a request to change tint level of a plurality of electrochromic devices, and consulting transfer functions for tint level relative to drive for each of the plurality of electrochromic devices, wherein at least one of the plurality of electrochromic devices has a transfer function differing from at least one other of the plurality of electrochromic devices. The method includes driving each of the plurality of electrochromic devices in accordance with the transfer functions, so as to coordinate tint level or rate of change of tint level across the plurality of electrochromic devices.
Abstract:
A wall controller is provided. The wall controller includes a projection screen having an input device and a projector arranged to project a digital image onto the projection screen from the projector, wherein the projector has an optical axis that is non-orthogonal to the projection screen. The wall controller includes a housing having the projection screen mounted thereto at a first end of the housing, the housing having the projector at a second end of the housing. The housing is dimensioned to fit the second end of the housing through an aperture in a first wall, fit the second end into a wall space between the first wall and a second wall, and fit a majority of the first end of the housing into the aperture until the projection screen is parallel to a surface of the first wall and a front portion of the projection screen is flush with, recessed in or extends from the surface of the first wall. The aperture dimensioned to fit the first end of the housing or the front portion of the projection screen.
