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.

The present invention describes a liquid crystal composite tunable device for fast polarisation-independent modulation of an incident light beam comprising: (a) two supporting and functional panels, at least one of them coated with a transparent conductive electrode layer and with optionally at least one additional layer selected from an alignment layer, antireflective coating layer, thermochromic or electrochromic layer, photoconductive or photosensitive layer, and (b) a composite structure sandwiched between said two panels and made of a liquid crystal and porous microparticles infiltrated with said liquid crystal. The porous microparticles have an average refractive index approximately equals to one of the liquid crystal principal refractive indices, matching that of the liquid crystal at one orientational state (for example, parallel n.sub.∥), and exhibiting large mismatch at another orientational state (for example, perpendicular n.sub.⊥). This refractive index mismatch between said microparticles and said liquid crystal is tuned by applying an external electric or magnetic field, thermally or optically.

A structural body includes a refrigerant between a first plate and a second plate. A circulation structural part between the first and second plates includes a reservoir portion provided on a first plate side. In the circulation structural part, the refrigerant from the reservoir portion which has evaporated due to heat of the first plate side reaches a second plate side, condenses on the second plate side and is returned to the reservoir portion again. A temperature sensitive mechanism is in a first state when a temperature of the first plate side is equal to or higher than a predetermined temperature to allow refrigerant circulation, and is in a second state different from the first state when the temperature is lower than the predetermined temperature to prohibit the refrigerant circulation.

Described is a window (1) for civil and industrial buildings, comprising a load-bearing frame (2) for a pair of sheets (3, 4) made of optically transparent material: a first sheet (3) and a second sheet (4) which have a relative face facing, respectively, towards the outside and towards the inside of a building (9) on which the window (1) is mounted. There are also means (11, 12, 13) for converting the energy of incident sunlight into electricity, by means of the photovoltaic effect interposed between the above-mentioned sheets (3, 4).

A composite panel element for guiding light, a window having the same, and a method for producing the same. To provide a composite panel element with good light guiding properties and being optically transparent and homogeneous, the composite panel element for guiding light has a first panel element with a first microstructure on a first inner surface and a second panel element with a second microstructure on a second inner surface. The first and the second microstructure have respective depressions/elevations. The panel elements are arranged such that the first and the second inner surface are facing one another, and the first and second microstructure are arranged such that internal micro-cavities are formed between the microstructures. The first and second microstructure have respective planar-contact adhesion sections for force-lockingly securing the panel elements to one another and/or corresponding latching sections for form-lockingly and/or force-lockingly securing the panel elements to one another.

An insulating glazing includes a first pane, a second pane, an inner spacer frame arranged between the panes, which, together with the panes, delimits an inner interpane space, a surrounding outer spacer frame arranged between the panes, which is arranged on the outward facing side of the inner spacer frame, wherein the inner spacer frame consists substantially of a first hollow profile spacer and the outer spacer frame consists substantially of a second hollow profile spacer, the inner spacer frame and the outer spacer frame are in each case connected together to the first pane and the second pane via a primary sealant, an outer interpane space between the outer side of the outer spacer frame and the first pane and the second pane is filled with a secondary sealant.

A laminated glass pane (1) comprises a first glass pane (10A), a second glass pane (10B) and an optically active film (20) laminated between the glass panes. The optically active film comprises a first conductive layer and a second conductive layer separated by at least one intermediate layer. The first and second conductive layers are contacted by a first (12A) and second (12B) connection wire, respectively. The optically active film is fully covered by both glass panes. Both the first and the second connection wires protrude out from the active film passing a first edge (14A) of the first glass pane in a same direction (18). The second glass pane protrudes outside the first edge of the first glass pane in the direction by an off-set distance (16). The off-set distance is at least equal to a smallest width of the first and second connection wires.
