摘要:
A nickel-base superalloy article, such as a gas turbine stationary flowpath shroud that has previously been in service, is repaired by applying a restoration coating to a surface of the article. The restoration coating is applied by providing a precursor mixture, wherein the precursor mixture has no more than about 15 weight percent chromium and no more than about 0.01 percent yttrium, and wherein the precursor mixture includes a higher-melting-point alloy component and a lower-melting-point alloy component. The precursor mixture is applied to the surface of the article, in a form such as a preform of the alloy components. The article with the precursor mixture applied to the surface thereof is heated to a sufficiently high temperature to melt the lower-melting-point alloy component, thereby forming the restoration coating on the surface of the article.

A sigma-delta analog-to-digital converter (10) having DEM (14) facilitated data weighted averaging to select specific unit elements of a negative feedback loop digital-to-analog converter (15), which DEM (14) is comprised substantially of transmission gates that contribute little to propagation delay. As a result, the feedback signal provided by the feedback loop is not more than one clock cycle behind the present coded output of the ADC (10) itself. As a result, higher resolution converters can be realized. The DEM (14) utilizes a repeating sequence to select specific unit elements. In some embodiments the direction of sequence usage is reversed in various ways to aid in reducing harmonic distortion.

Methods and systems for managing interactive features associated with multimedia content are disclosed. One method includes applying a container to multimedia content using one or more computing systems, the container defining an interface through which metadata external to the multimedia content is linked with one or more portions of the multimedia content. The method further includes receiving a request for the multimedia content from a content consumer. The method also includes associating a set of metadata describing one or more interactive features with the multimedia content, the set of metadata linked to at least a portion of the multimedia content via the container and selected from a database including metadata defining interactive features capable of being associated with the multimedia content. The method also includes, upon receiving a request for playback of the multimedia content, providing the multimedia content and the one or more interactive features to the content consumer.
摘要:
Embodiments of the present invention generally provide a plasma source apparatus, and method of using the same, that is able to generate radicals and/or gas ions in a plasma generation region that is symmetrically positioned around a magnetic core element by use of an electromagnetic energy source. In general, the orientation and shape of the plasma generation region and magnetic core allows for the effective and uniform coupling of the delivered electromagnetic energy to a gas disposed in the plasma generation region. In general, the improved characteristics of the plasma formed in the plasma generation region is able to improve deposition, etching and/or cleaning processes performed on a substrate or a portion of a processing chamber that is disposed downstream of the plasma generation region.

The apparatus for mounting a mobile information handling device further comprises a dock connecting assembly suitable for providing docking of a peripheral device.
摘要:
Correcting a temperature measurement of a target sensed at one temperature sensor in an asset tracking device by using another temperature sensor. The asset tracking device includes at least one heat source that affects the temperature sensor for sensing the temperature of the target. The other temperature sensor measures temperature at a location in the asset tracking device. The relationships between an actual temperature of the target and the temperature measured at the two sensors are established through experiments or model. Using the relationships, the measured temperature of the target can be corrected to obtain a corrected temperature of the target.

Medical devices, such as endoprostheses, and methods of making the devices are described. In one embodiment, a medical device having a body of interconnected bands and connectors forming an elongated tubular structure having an inner luminal wall surface, an outer abluminal wall surface and a side wall surface, and defining a central lumen or passageway, wherein said inner luminal wall surface and side wall surface of the bands and connectors form transverse passageways through the elongated tubular structure is described. One or more wall surfaces of the tubular structure can bear a coating whose selected regions define at least one depression. The coating can further include at least one biologically active substance.

Methods and systems for detecting objects of interest in multimedia content are disclosed. One method includes receiving multimedia content at one or more computing systems, and generating a plurality of scenes from the multimedia content, each of the plurality of scenes including one or more candidate objects of interest. The method also includes receiving selection of one or more of the candidate objects of interest as objects of interest, and defining one or more actions to be taken with respect to one or more of the objects of interest. The method further includes generating metadata associated with each of the objects of interest, the metadata defining actions to be taken with respect to the one or more of the objects of interest.
摘要:
Yeast cells having an exogenous lactate dehydrogenase gene ae modified by reducing L- or D-lactate:ferricytochrome c oxidoreductase activity in the cell. This leads to reduced consumption of lactate by the cell and can increase overall lactate yields in a fermentation process. Cells having the reduced L- or D-lactate:ferricytochrome c oxidoreductase activity can be screened for by resistance to organic acids such as lactic or glycolic acid.
