Publication number: 20100231510Abstract: A front light guide panel including a plurality of embedded surface features is provided. The front light panel is configured to deliver uniform illumination from an artificial light source disposed at one side of the font light panel to an array of display elements located behind the front light guide while allowing for the option of illumination from ambient lighting transmitted through the light guide panel. The surface embedded surface relief features create air pockets within the light guide panel. Light incident on the side surface of the light guide propagates though the light guide until it strikes an air/light material guide interface at one on the air pockets. The light is then turned by total internal reflection through a large angle such that it exits an output face disposed in front of the array of display elements.Type: ApplicationFiled: March 16, 2010Publication date: September 16, 2010Applicant: QUALCOMM MEMS Technologies, Inc.Inventors: Jeffrey B. Sampsell, Russell W. Gruhlke, Mark Mienko, Gang Xu, Ion Bita

Patent number: 7768084Abstract: A semiconductor sensor including a plurality of pixels, each of which includes a fluorescent molecule layer and a photosensitive layer. The fluorescent molecule layer converts light incident on the pixel to surface plasmons. The photosensitive layer generates a light detection signal representative of an intensity of light incident on the pixel in response to the surface plasmons in a region of the sensor which is close enough to the surface of the pixels that electronic crosstalk between the pixels does not occur.Type: GrantFiled: May 31, 2006Date of Patent: August 3, 2010Assignee: Aptina Imaging Corporation, Inc.Inventors: Russell W.

Patent number: 7737959Abstract: A detection system. The detection system includes a substrate, a laser, and a sensor array. The substrate includes a first surface, a second surface conceptually divided into multiple areas, and a third surface. The laser is configured to emit electromagnetic radiation into the substrate and incident subsequently onto second surface areas. The sensor array is configured to capture electromagnetic radiation reflected from the second surface. If a first dielectric, having first dielectric constant, is in contact with some areas, electromagnetic radiation incident thereon experiences total internal reflection and if a second dielectric having second dielectric constant is in contact with other areas, some of the electromagnetic radiation incident thereon is reflected back into the substrate by the second dielectric.Type: GrantFiled: September 8, 2005Date of Patent: June 15, 2010Assignee: Avago Technologies ECBU IP (Singapore) Pte.

Patent number: 7483065Abstract: Imaging systems and methods are provided. One exemplary system incorporates multiple lenses that are individually configured to receive visible light from an object to be imaged, and to direct this light upon a corresponding sensor array. Luminance information is then derived from signals generated in one or more of the sensor arrays. When chrominance information is desired, an optical filter is interposed between a lens and the corresponding sensor array. The mosaic pattern contained in the optical filter is tailored to provide advantageous chrominance information. One or more such filters with different mosaic patterns may be employed. The luminance and chrominance information obtained from the sensor arrays are combined to generate an image of the object.Type: GrantFiled: December 15, 2004Date of Patent: January 27, 2009Assignee: Aptina Imaging CorporationInventors: Russell W.
