  • Patent number: 7707025
    Abstract: A method of translating an input sentence in a source language to an output sentence in a target language uses a store comprising a plurality of example sentences. A base example sentence is chosen from the store based on a comparison of the input sentence with a plurality of example sentences, and its paired translation is used as a translation basis. A portion of the input sentence differing from a corresponding portion of the base example sentence is identified. A portion of the translation basis aligned with the base example unmatched is located. The input unmatched portion is used to select a set of subsidiary example sentences from the store. A choice of possible translations corresponding to the input unmatched portion is determined from the set of subsidiary example sentences. A translation is selected from the choice based on a predetermined selection algorithm.

  • Patent number: 7706017
    Abstract: Systems and methods for rendering a document in a native format at an imaging device using a host service for rendering into printer ready data. Documents/images are despooled to an imaging device in their native format for printing, wherein the imaging device includes the capability of discovering application/print server processes that render the document in its native format into a format compatible with the imaging device. The imaging device broadcasts job rendering requirements to one or more application/imaging servers, which in turn provide a response to the broadcast. One or more of the application/imaging servers are selectively chosen for use in rendering the document/print job, providing the device specific rendered job to the imaging device for rendering. In addition, when multiple compatible services are available, an optimal host service is determined and used for rendering into printer ready data.

The semiconductor substrate includes a P-type semiconductor substrate, a P-type semiconductor epitaxial layer, an N-type semiconductor body region, and a P-type semiconductor source diffusion. The substrate, the epitaxial layer, the body region, and the source diffusion are adjacently formed in this order. A P-type semiconductor channel region formed of a SiGe layer is provided on a bottom surface and a side wall of the trench region. This facilitates carrier movement in the channel region, reducing ON resistance of the Trench MOSFET. Thus, a Trench MOSFET allowing reduction in the ON resistance without reducing a breakdown voltage is realized.
