A window blind assembly to provide illumination to the interior of a room and to prevent sunlight from entering the room includes a multitude of the light emitting diode (LED) slats mounted in the window opening of a window frame and being rotatably connected to the window frame: a controller being embedded in the window blind assembly and configured to control the function of each row of the LED slats.

A window replacement panel including an air conditioning vent incorporated into it. A window assembly may be attached to a decorative panel with a vent disposed on a first side, and a coupling for an AC duct on an opposite side. The window may be a single, double pane, insulated, uninsulated or the like. The panel may be clad with material to harmonize with the building exterior, and the exterior vent presents a pleasing appearance. The combination of window and panel may be sized to replace an existing window, or may be used in new construction.

A multifunctional skybox bungalow integrates four devices: a dehydrator, sauna, skybox, and wind-redirecting structure. Equipped with adjustable louver blades linked to side gutter beams, it shields against rain and modulates sunlight entry. These blades house solar-rechargeable batteries, powering LED lights and reducing environmental impact. Solar panels on the blades harness solar energy, enhancing bungalow autonomy from power outlets. The design incorporates panel frames with inserts, converting the bungalow into a sauna, skybox, or dehydrator, offering wind protection and insulation. Louver braces within the frames allow louver repositioning and wind direction control. Axis pins grant eight locking points, enabling various louver functionalities. An inner-track insert facilitates curtain or screen attachment, ensuring privacy and protection. Features also include an extending-and-retracting door, door-spool housing, drainage, and base-plate elements for stability on uneven terrain, anchored securely with tube-screws and bolts.

A device for forming a jalousie includes at least first and second louvres pivoting about a common axis between a position in which the two louvres overlap and a position of angular separation of the louvres about the common axis. Preferably, the first louvre is at least partly translucent and the second louvre is opaque.

A shutter including a frame, a first blade set, a second blade set, a power source and a blade driving system is provided. The frame has a frame body. The first blade set and the second blade set are disposed on the frame body of the frame. The power source is disposed in the frame body. The blade driving system connects the power source, the first blade set and the second blade set for rotating the first blade set and/or the second blade set to rotate.

A modular photovoltaic louvered device having a rectangular framework; a plurality of photovoltaic louvre panels engaged in parallel within the framework, and electrical connector bearings interfacing each louvre panel and the framework, allowing the panels to rotate through a range and electrically connecting each panel to electronics within the framework. Each louvre panel includes: a transparent outer; a plurality of upper upwardly orientated photovoltaic cells operatively facing an upper surface; a plurality of lower downwardly orientated photovoltaic cells facing a lower surface; and a reflector located between the lower photovoltaic cells and the transparent outer. Each of the plurality of upper and lower photovoltaic cells occupy a surface area less than the photovoltaic louvre panels such that, light may pass through the transparent outer to a photovoltaic panel beneath such that the light captured by the device is increased by the lower photovoltaic cells being able to receive reflected light.

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 invention relates to a unit for covering and uncovering a surface using adjustable slats (3), comprising: for each slat (3), a set of two carriages (10.sub.1, 10.sub.2) guided in translation along guide tracks (8); a system (II) for moving the slats (3), comprising two movement motors (12) for each carriage pair (10.sub.1, 10.sub.2) equipping a slat, each motor being mounted in a different carriage; a system (I) for orientating the slats (3), comprising at least one orientation motor (14) for each carriage pair equipping a slat, said at least one motor being mounted in at least one of the carriages; and a control device for moving at least part of the slats in translation and orientating said slats.
