We disclose a roller shade which may move the roller fabric to position either a light reflecting section or a heat absorbing section of the roller fabric toward a window. The two sections may be on opposite sides of a sheet of roller fabric which is connected to the roller tube at one end. The roller shade may wind the roller fabric around the roller tube then reverse the side of the roller fabric which faces the window. Alternatively, the roller fabric may be a continuous loop of fabric that includes a light reflecting section and connected to a heat absorbing section. The roller shade may move the continuous loop of fabric to position either section toward the window. The roller shade may include sensors, a motor, and a controller. The controller may be programmed to reverse the roller fabric in response to a sensor measurement.

A dual curtain closure system for covering a portal wherein each curtain has a length greater than the length of the lateral margins of the portal, a first end fixedly attached across the portal at an upper end thereof, and a second end folded back on itself to define an upwardly opening pocket. An elongated rod is supported within each pocket. A first spindle winds and unwinds the first curtain and a second spindle winds and unwinds the second curtain. A drive motor is operable to simultaneously rotate the first and second spindles such that the upwardly opening pockets of the curtains are concomitantly raised or lowered. A predetermined distance between the rods is maintained as the pockets are raised or lowered, which facilitates sealing of the curtains to the lateral margins of the portal as the curtains are lowered.

A self-powered dynamic photovoltaic sunshade system having sunshades constructed of lightweight ETFE panels covered with at least one thin film of photovoltaic cells. The sunshades track the sun by light detectors, and move against the sun from east to west to block direct rays. The ETFE fabric is stretched on a lightweight frame, which rotates vertically around its axis as a pivotal panel for maximum solar protection. Sunshades rotate to face the sun by day, and reset to a starting position at night. Each sunshade is rotated by a stepped electric motor, powered by thin film(s) of solar photovoltaic cells. Sunshades are suspended between an electric motor shaft and a lower hinge. The sunshades are designed to provide sustainable dynamic shading for building facades exposed to different sun angles, are self-powered, and can generate electric power for other building functions, such as lighting and fan ventilation inside a building.

A window assembly for use in a vehicle including a window frame including a first end and a second end opposite the first end, and an opaque shade movable relative to the window frame, wherein the opaque shade includes a first tab formed at a bottom end of the opaque shade. A transparent shade is movable relative to the window frame, wherein the transparent shade includes a second tab formed at a bottom end of the transparent shade. The first tab and the second tab are configured for selective integration with each other to enable dependent movement of the opaque shade and the transparent shade with each other, and to enable independent movement of the opaque shade and the transparent shade relative to each other.

In one aspect, a cordless covering may include a roller and a shade panel configured to be wound around and unwound from the roller to move the shade panel between an extended position and a retracted position. The shade panel may include a front panel, a back panel, and a plurality of vanes extending between the front and back panels. The covering may also include a roller shaft extending through the roller and a tilt adjustment mechanism coupled to the roller shaft. The tilt adjustment mechanism may be configured to rotate the roller shaft to adjust a tilt angle of the vanes between an opened position and a closed position.

A privacy partition assembly for a cabin environment including a housing, an extension mechanism, and a partition. The extension mechanism has a retracted condition and an extended condition. A leading link moves away from the housing in a first direction when the extension mechanism transitions to the extended condition. The partition has a leading edge engaged with the leading link such that, when the extension mechanism transitions, the leading edge of the partition moves away from the housing. The extension mechanism includes a jointed first arm attached to a first end of the leading link, and a jointed second arm attached to a second end of the leading link. The jointed first and second arms extend when the extension mechanism transitions from the retracted condition to the extended condition thereby moving the leading link away from the housing. A roller maintains the partition in a taut condition.

A double-layer Roman shade folding structure includes a bracket. The bracket is provided with an outer curtain fabric, a roller tube, and an inner curtain fabric. The outer curtain fabric is provided with a plurality of strip-shaped limiting members that are arranged horizontally and spaced apart at equal intervals. An opening is defined between the limiting members and the outer curtain fabric for the inner curtain fabric to pass therethrough. When the bottom end of the inner curtain fabric drives the bottom end of the outer curtain fabric to be moved up, the plurality of limiting members are pushed and moved up in sequence so that the outer curtain fabric is folded and overlapped continuously.
