  • Contact text detection in scanned images
    Patent number: 8731296
    Abstract: A device and method for identifying text pixels that are erroneously classified as non-text pixels, includes accessing an image region containing a non-text component. For each non-text component within the image region component, only one determines if there are any long line structures within the bounding box defined by the non-text component. If the long line structures are greater than a predefined percentage of the span of the dimension of the bounding box parallel to the line structure, then the line structure is removed. Any remaining non-text pixels within the bounding box are reclassified as text-pixels.

  • Method and apparatus for efficient three-dimensional contouring of medical images
    Patent number: 8731258
    Abstract: A technique is disclosed for generating a new contour and/or a 3D surface such as a variational implicit surface from contour data. In one embodiment, B-spline interpolation is used to efficiently generate a new contour (preferably a transverse contour), from a plurality of input contours (preferably, sagittal and/or coronal contours). In another embodiment, a point reduction operation is performed on data sets corresponding to any combination of transverse, sagittal, or coronal contour data prior to processing those data sets to generate a 3D surface such as a variational implicit surface. A new contour can also be generated by the intersection of this surface with an appropriately placed and oriented plane. In this manner, the computation of the variational implicit surface becomes sufficiently efficient to make its use for new contour generation practical.

  • Logical design flow with structural compatability verification
    Patent number: 8732651
    Abstract: A design system provides data structures to store parameters of physical structures that can be viewed and modified in a front-end process through a logical design interface. In this way, system behavior defined by component structure can be evaluated and modified through a schematic representation of the data, regardless of a state of data representing the physical layout of interconnected physical structures. In electric circuit applications, for example, high frequency circuits can be incrementally designed and evaluated through structural parameters defined in a schematic diagram data abstraction without modifying and evaluating a layout data abstraction of the circuit directly.

  • Making nanostructured porous hollow spheres with tunable structure
    Patent number: 8728361
    Abstract: Hollow, porous, spherical metal-carbon composite particles, having nanostructures, are prepared from suitable precursor solutions containing metal-organic ligand coordination complexes with template. Such precursors may be made for each elemental metal to be in the spherical particles. The precursor solution is atomized as an aerosol in an inert gas stream and the aerosol stream heated to decompose the organic ligand portion of the precursor leaving the spherical metal-carbon composite or metal alloy-carbon composite particles. The organic ligand serves as a structure directing agent in the shaping of the spherical particles after the ligand has been removed. Other materials may also be used as permanent or removed templates. The morphology of the particles may be altered for an application by varying the preparation and composition of the metal precursor material, and the optional use of a template.
