  • Patent number: 7560053
    Abstract: Thermoelectric materials with a high Seebeck coefficient and a large power factor are provided. The materials are impact resistant and resistant to heat-distortion. Such materials include a rare earth element, Bi, and Te and have a rhombohedral crystal structure. In some examples, the rare earth element is selected from the group consisting of Ce, Sm and Yb. Such materials can be formed as films with a thickness of from 0.01 to 500 ?m on a resin substrate. Production methods may include laminating different types of layers of thickness of 20 nm or less and heat-treating the resultant composition-modulated composite. The material may be separated from a substrate for sintering.

  • Publication number: 20090024671
    Abstract: Described is a technology by which a content management system (such as part of Microsoft® Office SharePoint® Server) synchronizes data with an external (e.g., third-party) data storage system. For example, live video and/or on demand video webcasts may be stored on the external data storage system, but may be controlled by events created and edited at the content management system, even though the content management system does not directly support video content. In one example, an administrator creates or modifies an event at the content management system, and if the event is coordinated with the external data storage system, the content management system is synchronized with the external data storage system. One-way communication and/or two-way communication may take place for synchronization, including providing parameters to the content management system from the data store, or by sending notifications and queues to synchronize data with the content management system.

  • Patent number: 4115750
    Abstract: An improved bimetal actuator is disclosed. A thin film resistor is fixed to the high expansion side of a bimetal element and, when energized, generates sufficient heat to actuate the bimetal. The resistor has a serpentine configuration formed by a continuous series of loops, each successive loop having a greater width from the fixed to the free end of the bimetal, to provide differential heating of the bimetal and thus a greater movement of its free end for the power dissipated in the resistor.
