摘要:
The present invention relates generally to conductive polymer composites, electrically conductive adhesives, and methods of producing the same. The conductive polymer composites and electrically conductive adhesives may be used for electronic component interconnects, flip chip interconnections, electrical connections to circuit boards, jumper connections, or similar uses. The method of forming a conductive polymer composite includes mixing conductive metal flakes, functionalized conductive metal nanoparticles, and a polymer precursor and curing the polymer precursor to form a composite. In one embodiment, the conductive polymer composites may be composed of microparticles of silver flake and sintered silver nanoparticles between the silver flakes. The polymer composites have an electrical conductivity of less than 10−5 Ω·cm.

A light source comprising an excitation light source for providing excitation light, and an optical wavelength conversion member disposed at a distance from the excitation light source. The optical wavelength conversion member comprises an optical wavelength conversion material for converting the excitation light into stimulated light. The light source also comprises an optical-guiding member that allows the excitation light to be incident on the optical wavelength conversion material, and an optical-collecting member for collecting converted light originating from the optical wavelength conversion material. To separate the paths of the converted light and the excitation light, the etendue of the optical-guiding member is less than or equal to ¼ of the etendue of the optical-collecting member. This allows the optical-guiding member to draw in the excitation light while preventing the excessive escape of the converted light through the optical-guiding member.

An entity-based search system is described herein that detects and recognizes entities in Internet-based content and uses this recognition to organize search results. The system associates one or more entity identifiers with a web page and stores this information as metadata of the page in a search engine index. This metadata will enable entity-based queries as well as rich data presentations in a search engine result page (SERP), including grouping results by entities, filtering results by one or more particular entities, or re-ranking search results based on user preference of entities. Thus, the entity-based search system allows users to identify a particular entity the user is interested in finding, and to receive search results directly related to that entity.
摘要:
A solid state light source device for generating a constant broad band light useful in multiple SLM projectors. The light source device includes a blue or UV/near UV excitation light and a moving plate carrying wavelength conversion materials to convert the excitation light into a broad band light. The wavelength conversion materials include red, green, yellow and/or blue phosphors, and may pass some of the blue excitation light. The broad band light outputted by the phosphor plate includes at least two primary color components and has a constant intensity and spectrum as a function of time. The solid state light source device further includes a second light source such as a blue light source, and a light combination device which combines the output light of the moving phosphor plate and the light from the second light source into one beam of constant, broad band light.

A light source system and a projection system employing the same. The light source system includes a light source emitting an excitation light, a moving device carrying a wavelength conversion material and an adjustment device. The excitation light irradiates on the wavelength conversion material. When the moving device is in a periodical moving state, the light spot position irradiated by the excitation light on the moving device moves following a first working track. The adjustment device is used for adjusting the light spot position irradiated by the adjusted excitation light on the moving device so that it moves following a second working track. The first working track is separated from the second working track. The system can reduce the working load of the wavelength conversion material on the first working track, thus slowing the aging of the wavelength conversion material, and improving the life of the light source system.
