Window controller systems and methods are disclosed herein. In some embodiments, a window controller system for controlling multiple optically switchable devices comprises a printed circuit board comprising a first plurality of footprints to which a first plurality of components is mounted and a second plurality of footprints, wherein a subset of the second plurality of footprints is populated by a second plurality of components. The first plurality of components may comprise: a plurality of insulated glass unit (IGU) controllers, each configured to control an IGU of a corresponding plurality of IGUs operatively coupled to the window controller system; and a processing unit configured to control each of the plurality of IGU controllers. The second plurality of components may be selected based on a cable type and/or a protocol type used to provide power and data signals to the printed circuit board.

The present invention relates to variable optical transmission windows and window panels which are used for architectural applications, particularly in building entryway systems. This disclosure is directed to the use and powering of such panels in door and windows that, in part, physically open by manual or automatic sliding, tilting, pushing or rotating about the hinges, unless specifically mentioned otherwise. The doors may also have other electronic devices which provided added user functionality.

A switchable device for changing the opacity of at least a portion of a glazing is described. The switchable device comprises at least two (a first and a second) switchable regions in electrical communication with at least two (a first and a second) electrical connector regions. Each switchable region comprises an electrically actuated variable opacity layer between a first electrode and a second electrode, the first switchable region being arranged relative to the second switchable region such that upon connecting the first and second electrical connector regions to a suitable power supply, the opacity of the first and second switchable region changes such that at least two (a first and a second) portions of the switchable device have a change of opacity, the first portion of the switchable device having a different opacity to the second portion of the switchable device.

In an aspect of the present invention, a gasochromic dimming mechanism is provided which includes a gasochromic dimming component provided with a pair of transparent substrates, the transparent substrates being arranged to face each other, and a dimming part formed on one or both facing surfaces of the pair of the transparent substrates, wherein an optical property of the dimming part is reversibly changed by hydrogenation and dehydrogenation; and a hydrogen-air mixture gas supply unit that supplies a hydrogen-air mixture gas between the pair of the transparent substrates. The hydrogen-air mixture gas supply unit includes an electrolysis cell including a mixer for mixing hydrogen and air, a polymer electrolyte membrane, a porous electrode formed in the polymer electrolyte membrane as an anode, and an air supply unit that supplies the air to the mixer, the porous electrode being arranged on a flow channel of the air.

The present invention relates to optical power-limiting devices, and more particularly, to an optical power-limiting passive (self-adaptive) device and to a method for limiting solar power transmission in devices such as windows, using scattering level changes in a novel thermotropic composition that contains salt nano or microparticles embedded in a solid transparent host layer, where temperature change induces change in the refraction index of the matrix as well as of the embedded particles, creating a scattering layer, substantially reflecting the incident light thus limiting the amount of light passing through the window, green house covers, car sun roofs, solar panel windows and protection layers on housing roofs and walls, as a function of ambient temperature.

A damper providing varying damping force is provided. The damper may include a housing and a rotary member rotatably received the housing. The rotary member may rotate within the housing between defined end points of travel to define an angular range of travel of the rotary member. An outermost surface of the rotary member may be spaced inwardly from an inner surface of the housing defined between the end points of travel to define a gap between the outermost surface of the rotary member and the inner surface of the housing throughout the angular range of travel. The gap may vary in dimension depending on a rotational position of the rotary member to provide varying damping rates within the angular range of travel of the rotary member.

The present application discloses a switchable device, comprising a switching layer and a first conductive layer and a second conductive layer, where the switching layer is positioned between the first and the second conductive layer, and where at least one of the first and the second conductive layers comprises a plurality of isolating sections and a plurality of conductive sections, where the isolating sections and the conductive sections alternate over the area of the conductive layer, and where the switching state of the switchable device is controlled by touch motions.
