| 20080205078 | ILLUMINATION TILES AND RELATED METHODS - Illumination assemblies, components, and related methods are described. A plurality of illumination tiles may be arranged in a two-dimensional array. In one embodiment, an illumination tile comprises at least one solid state light-emitting device and a light guide including an edge constructed and arranged to receive light from the solid state light-emitting device, and a top emission surface constructed and arranged to emit light received by the edge, wherein the solid state light-emitting device is disposed under the top emission surface. In another embodiment, an illumination tile comprises at least one solid state light-emitting device and a light guide including a light input portion including an edge constructed and arranged to receive light from the light-emitting device and a top surface, and a light extraction portion including a top emission surface constructed and arranged to emit light received by the edge, wherein the top surface of the light input portion is offset vertically from the top emission surface of the light extraction portion. | 08-28-2008 |
| 20080205080 | TILED ILLUMINATION ASSEMBLY AND RELATED METHODS - Illumination assemblies, components, and related methods are described. An illumination assembly is provided that comprises a plurality of illumination tiles each having a light emission surface. The plurality of illumination tiles are arranged in a two-dimensional array. The illumination tiles are constructed and arranged so as to provide a substantially contiguous illumination surface comprising the light emission surfaces of the plurality of the illumination tiles. Each illumination tile is illuminated by at least one solid state light-emitting device. A method of local dimming an illumination assembly of a display (e.g., LCD) backlight unit is also provided. | 08-28-2008 |
| 20080290819 | LIGHT-EMITTING DEVICE DRIVER CIRCUITS AND RELATED APPLICATIONS - Driver circuits for light-emitting devices (e.g., light-emitting diodes), as well as systems and methods associated therewith are provided. | 11-27-2008 |

| 20090124224 | RADIO COMMUNICATION DEVICE, RECEIVER CONTROLLER OF A RADIO COMMUNICATION DEVICE, AND METHOD FOR SEARCHING FOR A RADIO CELL - Embodiments of the invention relate generally to a radio communication device, to a receiver controller of a radio communication device, and to a method for searching for a radio cell. In an embodiment of the invention, a method for searching for a radio cell is provided. The method may include scanning at least one frequency band of a first radio access technology, scanning at least one frequency band of a second radio access technology, wherein the at least one frequency band of the second radio access technology at least partially overlaps with the at least one frequency band of the first radio access technology, wherein at least one frequency sub-band of the first radio access technology is not scanned in the at least one frequency band of the second radio access technology. | 05-14-2009 |
| 20100330943 | METHODS FOR MEASURING RECEIVED SIGNAL STRENGTH INDICATION, MEASUREMENT DEVICES, AND RADIO COMMUNICATION DEVICE - In various embodiments, a method for measuring Received Signal Strength Indication is provided. The method may include carrying out a first partial Received Signal Strength Indication measurement for a plurality of mobile radio base stations, selecting at least one mobile radio base station out of the plurality of mobile radio base stations based on the result of the first partial Received Signal Strength Indication measurement for a second partial Received Signal Strength Indication measurement, and carrying out the second partial Received Signal Strength Indication measurement for the selected at least one mobile radio base station. | 12-30-2010 |
