Further, there is described a method of producing such a metal oxide thin film via sputtering and a thin film device with a metal oxide thin film of β-MoO.sub.3 that includes at least one doping element selected from the group Re, Mn, and Ru.

Disclosed is a retractable lighting fixture having a retractable LED lighting layer. One or more optical layers (40, 240A/B, 340A/B, 440) may optionally be provided over the LED lighting layer (30, 230, 330, 430). The optical layer(s) and the LED lighting layer may optionally be movable relative to one another between at least being in an expanded spaced relation to one another and a compressed relation to one another. One or more LEDs (34, 134, 234A/B, 334A/B, 434) on the LED lighting layer may be individually controllable and such LEDs (34, 134, 234A/B, 334A/B, 434) may be selectively extinguished when they are in a retracted position.

A window shade system is presented that combines the benefits of roller shades with draperies. In one arrangement a fascia having a front plate and a bottom plate includes a track positioned in the forward lower end of the fascia. The fascia is configured to be attached to a plurality of brackets. One or more roller shades having roller shade material attached to a tube are connected to the brackets. A plurality of carriers are positioned in the track and one or more draperies are attached to the plurality of carriers in the track. This arrangement presents a dual functioning window shade wherein roller shade material may be opened and closed by raising and lowering the roller shade material by rotating the tube of the roller shades raised, and the drapery shade material may be opened and closed by sliding the drapery shade material along the length of the track.

A multipurpose advertisement board comprising: a window; a vertical film comprising multiple film strips connected in series; a first image expression device comprising an operating unit rotatably connected to a vertical winding roller in upper and lower portions of the frame that vertically move the vertical film to display the multiple film strips in order; a horizontal film comprising multiple film strips connected in series; a second image expression device installed on the window frame, wherein the second image expression device comprises an operation unit rotatably connected to a horizontal winding roller installed in left and right portions of the window frame to rotate or release the horizontal film, thereby horizontally moving the horizontal film so that the multiple film strips of the horizontal film overlap with the film strips of the vertical film to make a combined image.

A lighted roll up door assembly may include a roll up door including interconnected slats movable along tracks, and a lighting element configured to be attached to an exterior side of the roll up door. The lighting element can be mounted so as to direct a substantial portion of the light output toward the roll up door and below a horizontal direction so as to light a portion of the door and an adjacent area below the door at least partially by reflection when the door is in a closed position and so as to light an area on an interior side of the roll up door when the door is in a opened position. The lighting element may be mounted to a fixed or movable member attached to a slat of the roll up door.

A load control system may control an electrical load in a space of a building based on one or more parameters regarding the physical condition of an occupant. The parameters may be gathered by one or more sensing devices. The sensing devices may be included in a mobile device. A system controller may receive the parameters and may automatically control the electrical loads in response to the parameters. The system controller may control the electrical load to attempt to adjust the physical condition of the occupant in response to the sensed parameters. The system controller may control the electrical load to provide an alert, an alarm, and/or a warning in response to the sensed parameters.

A window or door element includes a frame and an insulated glazing unit removably disposed in the frame, the insulated glazing unit including at least one first electrical connection pin and the frame including at least one second electrical connection pin, the at least one first electrical connection pin of the insulated glazing unit being in electrical contact with the at least one second electrical connection pin of the frame when the insulated glazing unit is inserted into the frame.

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.

Aspects of the present disclosure involve a transparent structure. The structure may include at least one light source, a transparent light-carrying guide layer optically coupled with the at least one light source. The structure may include refractive layers where a light absorbing feature is operably associated with the light-carrying guide layer to absorb any light not internally reflected in the light guide layer, at least adjacent the light source.

A controllable privacy structure, such as a window or door, may include an electrically controllable optically active material connected to a driver. The driver can control the application and/or removal of electrical energy to the optically active material to transition from a scattering state in which visibility through the structure is inhibited to a transparent state in which visibility through the structure is comparatively clear. The driver may need to be located in relatively close physical proximity to the privacy structure the driver is intended to control. Devices, systems, and techniques are described for discretely positioning a driver relative to a privacy structure to be controlled.
