  • Patent number: 7268373
    Abstract: A semiconductor may contain a plurality of circuits each comprising at least one thyristor having a base region. The base region of at least one of the thyristors has a different doping profile than the others. When a bias circuit is used to bias the thyristors, the effect of biasing on the thyristors is found to be affected by the doping profile. In a specific embodiment, the doping concentration is higher near an electrode of the thyristor than near a supporting substrate. The different doping profiles can be achieved by using different ion implant energies.

  • Publication number: 20070033004
    Abstract: Disclosed herein are systems and methods to incorporate human knowledge when developing and using statistical models for natural language understanding. The disclosed systems and methods embrace a data-driven approach to natural language understanding which progresses seamlessly along the continuum of availability of annotated collected data, from when there is no available annotated collected data to when there is any amount of annotated collected data.

  • Publication number: 20070005584
    Abstract: The embodiments include a system and a method for establishing a communication connection after searching the World Wide Web. The system can include a first communication device for forming at least one communication connection between the first communication device and a second communication device, search means adapted to accept a query, access means can be adapted to search and identify relevant phone number information using the query, and create at least one icon to link the first communication device to a relevant phone number included in the relevant phone number information identified by the query, and reformulate the query if no relevant phone numbers are identified during the search. The system also includes click-to-dial means adapted to establish at least one communication connection from the first communication device to the second communication device.

  • Patent number: 7054191
    Abstract: A first and a second set of memory cells are connected to the same first word line and second word line. At the commencement of data writing, the first word line is set up. The first set of memory cells is read and temporarily stored into a buffer. At about the same time, the bit lines of the second set of memory cells is set up. After completion of reading of the first set of memory cells, the bit lines of this set of memory cells are set up (while the setting up of the bit lines of the second set of memory cells continues). After the bit lines of both sets of memory cells are set up, the second word line is pulsed. At this time, written into both sets of memory cells begins, which comprises data previously read from the first set of memory cells and new data to be written into the second set of memory cells. It is found that this method reduces the overall write time.

  • Patent number: 6292683
    Abstract: The present invention relates to magnetic resonance imaging (MRI) and includes a method and apparatus to track motion of anatomy or medical instruments, for example, between MR images. The invention includes acquiring a time series of MR images of a region of interest, where the region of interest contains the anatomy or structure that is prone to movement, and the MR images contain signal intensity variations. The invention includes identifying a local reference region in the region of interest of a reference image and acquired from the time series. The local reference region of the reference image is compared to that of the other MR images and a translational displacement is determined between the local reference region of the reference image and of another MR image. The translational displacement has signal intensity invariance and can accurately track anatomy motion or the movement of a medical instrument during an invasive procedure.
