  • Patent number: 7382663
    Abstract: An erase voltage generation circuit providing a uniform erase execution time and a non-volatile semiconductor memory device having the same, in which the erase voltage generation circuit includes a high voltage generation unit, a voltage level detection unit, an execution time checking unit and a discharging unit. The high voltage generation unit generates an erase voltage. The voltage level detection unit detects the erase voltage and generates a level detection signal. The level detection signal is activated when the erase voltage reaches a target voltage. The execution time checking unit generates an execution end signal that is activated in response to the lapse of an erase execution time from the activation of the level detection signal. The discharging unit discharges the erase voltage as a discharge voltage.

  • Patent number: 7177471
    Abstract: This invention relates to shape priors for level set representations. An embodiment of the invention comprises a first stage and a second stage. In the first stage, a shape model can be built directly on level set space using a collection of samples. The shape model can be constructed using a variational framework to create a non-stationary pixel-wise model that accounts for shape variabilities. Then, in the second stage, the shape model can be used as basis to introduce the shape prior in an energetic form. In terms of level set representations, the shape prior aims at minimizing non-stationary distance between the evolving interface and the shape model. An embodiment according to the present invention can be integrated with an existing, data-driven variational method to perform image segmentation for physically corrupted and incomplete data.

  • Patent number: 7152205
    Abstract: An adaptive transformation and User Interface system enables transformation of a file or document (e.g. an SGML, XML, HTML or other multimedia file or document) from one format to another format. The transformation supports error correction, filtering and collation of elements of a source document for output and is performed in response to control information comprising transformation parameters. The system transforms a document encoded in a language including presentation style determination attributes from a first format to a different second format. The system includes a source of transformation parameters determining a desired presentation style and content structure as well as an input document processor. The input document processor transforms a received input document in a first format by parsing the input document and collating elements of the input document into a hierarchically ordered structure representing an intermediate document structure.
