A fenestration system includes one or more of a light modulation controller or ventilation modulation controller. The light modulation controller is in communication with at least one light modulation element of a fenestration assembly having a frame and a panel. The light modulation controller includes a light prescription module configured to provide a specified light prescription for the building interior. A lighting difference module is configured to determine a prescription difference between the specified light prescription and ambient light. A dynamic light module of the light modulation controller operates the at least one light modulation element according to the prescription difference. The ventilation modulation controller is in communication with at least one operator configured to open and close the panel. A ventilation prescription module provides a specified ventilation prescription for the building interior, and a dynamic ventilation module implements panel closing and opening according to the specified ventilation prescription.

An enclosed venetian-blind shade for a window includes a plurality of blinds with an adjustable pitch, a transparent pane and a reveal arranged in front of the blinds that enclose one side of the blinds, and a handle assembly to move and secure the blinds in place. An aircraft window shade includes a plurality of blinds coupled to a wire loop, a drive shaft with a gear coupled to the wire loop, and a rotatable dial that interconnects with the gear such that rotation of the dial alters a pitch of the blinds. A window shade system for directing and blocking light from an aircraft window includes a plurality of blinds coupled to a pulley assembly for adjusting a pitch of the blinds, a handle assembly for raising/lowering the blinds, and a carriage assembly for securing the blinds.

A window blinds assembly that can include slats installed either horizontally or vertically forming a window blind. The slats include a one-way-see-through layer and are tinted, wherein the level of tint can be electronically manipulated. The opening and closing of the slats are electronically operated by a motor. A remote control can be used to communicate with the assembly. A display can also be includes for displaying messages.

An at least partially self-powered photovoltaic sunshade and display system is provided, including a plurality of panels arranged in an array. Each of the plurality of panels has two sides, including a first side including a plurality of photovoltaic cells or a photovoltaic layer, and a second side having an array of light-emitting elements. The at least partially self-powered photovoltaic sunshade and display system includes energy storage means that receives charge from the plurality of panels and provides electrical power to the array of light-emitting elements. Each of the plurality of panels is rotatable about an axis such that the two sides are respectively rotatable towards or away from the sun, and towards or away from an exterior environment.

An environment-friendly material includes 50 wt % to 70 wt % of inorganic mineral powder, 20 wt % to 45 wt % of polyolefin, and 5 wt % to 15 wt % of auxiliary agent. The inorganic mineral powder contains calcium carbonate; the polyolefin may be linear low density polyethylene, low density polyethylene, medium density polyethylene, high density polyethylene, or polypropylene; and the auxiliary agent may be polyolefin elastomer, maleic anhydride grafted polyolefin elastomer, or maleic anhydride grafted polyethylene. The disclosure also provides a manufacturing method of window covering slat using the environment-friendly material and a window covering slat manufactured by the method.

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 covering for an architectural opening including a roller, an end rail, and a panel rotatable onto the roller and spanning between the roller and the end rail. The panel includes a front sheet, a rear sheet, and a cell spanning between the front and rear sheet. When the front sheet is at a first position relative to the rear sheet, the cell is open. When the front sheet is at a second position relative to the rear sheet, the cell is closed.

A window shade includes a reel and an aperture control module respectively assembled with a head frame, and a panel assembly including transversal vanes respectively connected with two panels. The reel is rotatable to wind and unwind the panel assembly. The aperture control module includes a positioning arm connected with a rubbing roller, and is operable to rotate the rubbing roller relative to the positioning arm and to displace the positioning arm and the rubbing roller between two positions, the rubbing roller being displaced away from a sidewall of the head frame in a first position and pressing the panel assembly against the sidewall in a second position, the rubbing roller being further rotatable relative to the positioning arm in the second position to cause relative sliding between the two panels for switching the panel assembly from a closed state blocking light passage to an open state allowing light passage.
