Abstract: A method for fabricating a rear projection screen is described wherein two or more glass plates are held in a confronting generally parallel spaced relationship and a radiation curable liquid polymer resin is cast into the space between confronting surfaces of the glass plates, and the polymer resin is cured by irradiation with light of wavelength up to about 800 nanometers to form a laminated projection screen product. In one embodiment, any air remaining between the plates or in the liquid polymer resin is removed.

Abstract: A window shade system comprising a roller tube, a top casing, and a shade having a first end engaged with the roller tube and a second end engaged with the top casing such that the shade forms a bight between its ends that separates the shade into a front portion and a back portion. A rod is disposed in the bight. A lift mechanism, typically a motor, rotates the roller tube and moves the shade between a raised position where the bight is adjacent the top casing and a lowered position where the bight is distanced from the top casing. When the shade is in the lowered position, the front portion of the shade comprises a decorative fabric layer and the back portion comprises a sound attenuating layer, such as a polymer film with filler material or mass loaded vinyl. The window shade system typically comprises side casings that have channels for receiving the side edges of the shade.
