Abstract:
A panel assembly for a window shade includes a first and a second elongate strip adjacent to each other that are bonded to a support sheet. Each elongate strip has a first and a second edge opposite to each other, and a main strip portion between a first and a second margin, the first and second margin respectively adjoining the main strip portion along a first and a second folding line, the first margin extending between the first folding line and the first edge, the second margin extending between the second folding line and the second edge, the second margin including a third folding line substantially parallel to the second folding line. The first margin is bonded to the support sheet, and the second margin is bonded to the support sheet or the second elongate strip at a margin portion between the third folding line and the second edge.
Abstract:
According to some aspects, provided are curtain assemblies configured to operate in high wind environments. The curtain assembly can include first and second track guide including internal security rails. The internal securing rails moveably engage end portions of fabric stiffeners to provide stability in the curtain. In some embodiments, the securing rails include ramp portions to accommodate drift in the curtain and/or fabric stiffeners without compromising operation of the curtain.
Abstract:
The present disclosed subject matter is a curved reflective skylight curb insert which intercepts and reflects low sun elevation angle sunlight, thereby minimizing glare and providing more uniform illumination within the building below.
Abstract:
The present disclosure relates generally to light management constructions comprising microstructured prismatic elements useful in the preparation of sun-facing light redirecting films having reduced glare.
Abstract:
A manually operated override release mechanism for use with a motorized window shade assembly having a shade fabric with a leading edge, the shade fabric being disposed behind a pane and movable between an opened position and a closed position upon operation of a motor. The override release mechanism has an actuator movable between a first position and a second position and biased in the first position. The actuator has a first side secured to one end of a cable, and a second side. The other end of the cable is connected to the motor.
Abstract:
A window cover apparatus for covering a window is provided. The window has a window opening and a window frame surrounding the window opening. The window cover apparatus comprises a shade qovering having a front side, a rear side, a top edge, a bottom edge, a first side edge, and a second side edge. An adhesive strip is mounted nearingly adjacent the top edge on the rear side of the shade covering. The shade covering is constructed from a paper material covered with a first pattern. The shade covering is capable of being secured over at least a portion of the window opening.

Abstract:
An optical article for illuminating building interiors including a reflective grid and a light diffusing element positioned between the reflective grid and a light source. The reflective grid includes one or more arrays of transverse reflective surfaces and is configured to partially transmit and partially redirect incident light over a broad angular range.
Abstract:
A non rectangular controllable window covering, for a window frame of corresponding non rectangular shape and having a covering frame defining a base frame segment and a non rectangular frame segment together forming a covering frame to fit the non rectangular window frame, and a window covering supported in the covering frame, consisting of a first covering panel and a second covering panel spaced apart from one another, one of the covering panels being movable relative to the other, and, a control element connected to the moveable covering panel.
Abstract:
An optical article for directing and distributing light including an optically transmissive light diffusing sheet and a reflective grid disposed in energy exchange relationship with the diffusing sheet. The reflective grid includes one or more parallel arrays of reflective surfaces configured to partially transmit and partially redirect a parallel beam of light into one or more directions that are not coincident with the original propagation direction of the incident light beam.
