US #7559680- Light system with stacked light pipe structure
Dec 17, 2009
The present invention includes decorative, architectural, and building materials and methods of making these materials, using them or both. The present invention relates to an article of manufacture that includes a light source and a substrate with a plurality of volumes of material, where each volume is capable of transmitting light from one location to a second location on a surface of the substrate. The present invention also relates to an article of manufacture having a substrate with a first surface, and a volume of material contained within the substrate and adapted to transmit light from a first location on the first surface to at least a second location. The present invention also relates to methods of making the articles and to methods of transmitting information.
US #7547128- Light pipe containing material
June 12, 2007
The present invention relates to an article of manufacture for detecting motion that includes a substrate with a plurality of volumes of material, where each volume is capable of transmitting light from one location on a surface of the substrate to a second location. The present invention also relates to an article of manufacture having a motion detector with a substrate with a first surface, and a volume of material contained within the substrate and adapted to transmit light from a first location on the first surface to at least a second location. The present invention also relates to methods of making the articles and to methods of transmitting information and detecting motion.
US #7422354- Light scrambling system
June 12, 2007
The present invention relates to a light scrambling system that includes a substrate and a plurality of light pipes. The substrate includes a first surface and a second surface opposite the first surface. Each of the plurality of light pipes includes a first end on the first surface of the substrate, a second end on the second surface of the substrate, and at least one inside surface formed by a refractive index boundary. The light input is received by the first end at a plurality of input angles, and the light output is transmitted at the second end at a plurality of output angles. At least a portion of the input angles are different from at least a portion of the output angles, thereby scrambling the light received by the first ends of the light pipes and transmitted by the second ends of the light pipes.
US #7229203- Light pipe containing material
June 12, 2007
The present invention relates to an article of manufacture for detecting motion that includes a substrate with a plurality of volumes of material, where each volume is capable of transmitting light from one location on a surface of the substrate to a second location. The present invention also relates to an article of manufacture having a motion detector with a substrate with a first surface, and a volume of material contained within the substrate and adapted to transmit light from a first location on the first surface to at least a second location. The present invention also relates to methods of making the articles and to methods of transmitting information and detecting motion.
