  • Patent number: 9348571
    Abstract: A method of searching for and installing a software product on a device is provided. One or more capabilities needed by the device to be served by a software product are determined. The one or more capabilities needed by the device are communicated from a software life cycle management agent on the device to a yellow pages agent outside the device, the communicating comprising formulating a request comprising a list of the capabilities encoded in a description language that defines the capabilities semantically. Then locations of one or more software products matching the one or more capabilities needed by the device may be received from the yellow pages agent. One of the one or more software products to install may be selected based on automatically evaluated criteria. Then the selected software product may be downloaded using its received location, and the selected software product may be installed on the device.

  • Patent number: 9349171
    Abstract: The present disclosure presents systems and methods for correcting image artifacts on an x-ray image. X-ray images are obtained and processed with a correction algorithm that generates corrected pixel lines having pixels with corrected pixel values. The corrected pixel lines can then be processed with a filtering algorithm that generates filtered pixel line having pixels with a filtered pixel value. The bad pixel lines are replaced by the filtered pixel lines to generate corrected x-ray images.

  • Patent number: 9349186
    Abstract: The system and method of the invention combines target image intensity into a maximum likelihood estimate (MLE) framework as in STAPLE to take advantage of both intensity-based segmentation and statistical label fusion based on atlas consensus and performance level, abbreviated iSTAPLE. The MLE framework is then solved using a modified expectation-maximization algorithm to simultaneously estimate the intensity profiles of structures of interest as well as the true segmentation and atlas performance level. The iSTAPLE greatly extends the use of atlases such that the target image need not have the same image contrast and intensity range as the atlas images.

  • Patent number: 9349790
    Abstract: A semiconductor device or power electronic device is described. The device includes a pair of pole pieces, each having a profiled surface. A semiconductor body or wafer, preferably of wide bandgap electronic material, is located between the pole pieces and includes contact metallization regions. The semiconductor body produces an electric field that emerges from an edge region. Passivation means includes a first or radially inner part in contact with the edge region of the semiconductor body and which diffuses the electric field as it emerges from the edge region and a second or radially outer part. The second part of the passivation is in contact with the first part and provides a substantially void-free interface with the profiled surface of each pole piece. The device may be immersed in a dielectric liquid.
