Abstract: A microelectronic sensor device and a method for making optical examinations at a carrier for the detection of magnetic particles, for example, at a contact surface of the carrier by frustrated total internal reflection (FTIR), include a light source with a laser modulator for emitting an input light beam into the carrier. The input light beam is modulated such that optical interferences with reflections of the input light beam from the entrance window, or from other components of the carrier, are reduced or minimized. This can be achieved by a pulsed on/off modulation in which the first relaxation minimum of a currently emitted pulse (PN) coincides in the light source with the first relaxation maximum of a reflected pulse (PN-1?). By reducing the effect of interferences, the setup is less prone to disturbances from dimensional variations that are induced by thermal extension, for example.

Abstract: A high efficiency lighting system (100) is described that has a small etendue. This can be used, for example, for backlighting a display device such as a liquid crystal display (LCD), projection displays, as well as for general lighting purposes. A portion of the light from a light emitting device die (101) falls onto a fluorescent material (105,106), such as phosphor. Dichroic mirrors (107,109) prevent the light generated by the fluorescent material to return to the light-emitting device. The mirrors may also provide collimation of the generated light and the remainder of the light from the light-emitting device. In this way a high efficiency system is realized because little or no generated light is absorbed and the generated light does not have to travel through a fluorescent material layer and thus has a high chance to go in the desired direction.

Abstract: The invention relates to an ad-hoc peer to peer network for providing recommendations. User terminals (100, 103) of the data network comprise a local database (115) with community reference information. A processor (111) determines if a communication with a second user terminal (103) is possible and if so, communication is established by a direct wireless link.

The user terminal (100) also comprises a recommendation processor (117) which generates a recommendation based on the community preference information. The invention is particular applicable to small low cost terminals, such as mobile phones or wireless equipped Personal Digital Assistants.

Abstract: A light emitting device comprises a flip-chip light emitting diode (LED) die mounted on a submount. The top surface of the submount has a reflective layer. Over the LED die is molded a hemispherical first transparent layer. A low index of refraction layer is then provided over the first transparent layer to provide TIR of phosphor light. A hemispherical phosphor layer is then provided over the low index layer. A lens is then molded over the phosphor layer. The reflection achieved by the reflective submount layer, combined with the TIR at the interface of the high index phosphor layer and the underlying low index layer, greatly improves the efficiency of the lamp. Other material may be used. The low index layer may be an air gap or a molded layer. Instead of a low index layer, a distributed Bragg reflector may be sputtered over the first transparent layer.
