Abstract: Methods and systems for searching for objects. A plurality of Attributes can be assigned to each of a plurality of objects in a collection. Each of the Attributes can be assigned to a Kind. A search query can be received including at least one Attribute specified by a user. A list of Kinds can be displayed. The Attributes can be grouped into Kinds such that searching the objects to determine if the objects have a particular Attribute is not performed if the objects do not have Attributes of that Kind associated with an object to be searched. Grouped Attributes can be subdivided into smaller groupings and resulting subdivisions can be given a numerical score indicating how far a subdivision is from all or none.

Each Object is associated with a plurality of Attributes, each Attribute is associated with a Kind, and each Kind is associated with a plurality of Attributes. Search criteria comprising an Attribute is received. A Nonceattribute is created using the search criteria. A search utilizing the Nonceattribute is inputted. All Objects having the Nonceattribute are identified. All Attributes associated with the Objects are identified. All Kinds associated with the Attributes are identified. A ranking criterion is applied to identified Kinds and Attributes. The highest-ranked portion of the Kinds and the highest-ranked portion of the Attributes that can readably be shown in a search result display are displayed.

Abstract: A method includes obtaining first volumetric image data, which is acquired at a first time, including a region of interest with a structural feature located at a first position. The method further includes obtaining second volumetric image data, which is acquired at a second different time, including the region of interest with the structural feature located at a second different position. The method further includes determining a registration transformation that registers the first and second volumetric image data such that the at least one structural feature in the first volumetric image data aligns with the at least one structural feature in the second volumetric image data. The registration transformation is based at least on a contour guided deformation registration. The method further includes generating a signal indicative of the registration transformation.

Abstract: A local user obtains data on the response of internal tissues of a subject to a non-invasive imaging system, choosing sensor positions according to a geometric display. The data obtained are evaluated with respect to predefined quantitative values. The process of obtaining and processing the internal tissue response data is repeated until an image meeting predetermined image quality characteristics is obtained. Specific or general content of the image may be restricted by the local processor, with a distal processor receiving the obtained image data, so as to limit specific or general types of image information from being viewed by the local user, such as image data that can be used to identify the sex of a fetus within the subject.

Abstract: Known time reversal methods consist of three steps which may be listed as (i) the recording of signals and (ii) the time reversing of the recorded signals, and (iii) the transmission of the time-reversed signals. The first and third steps of the above process are retained, but the second step is modified. The empirical signal is transformed to fit mathematical forms taught by the mathematics of singularity and catastrophe theory that ensure a structural stability to the waveforms that will be received, when the time reversed signals are transmitted again. This structural stability ensures robustness of the waveform and the predominant direction of the flux of energy of the waveform, and improves controllability of the location of the high magnitude regions of the energy flux despite limited knowledge of the exact properties of the medium. Applications to drug delivery in the brain, and geophysical applications are envisaged.

Abstract: Techniques are provided for glyph rendering based on a polygon mesh having vertices located away from a glyph's outline. Skeletonisation may be used to establish polygonal skeletons in the interior region of a glyph and in the outside region of the glyph. Transepts oriented away from the glyph's outline may be generated for nodes on the glyph's outline. A polygon mesh may be generated with vertices constrained to be selected from a set of candidate vertices comprising termination points of transepts, skeleton nodes, and/or points on the glyph's bounding boxes. Implicit forms may be determined from curves or lines representing segments of the glyph's outline, without use of Bézier control points and endpoints. These implicit forms along with tessellation data may be provided to a computing device as glyph rendering data for rendering the glyph at runtime.

Abstract: A contents display and search system for navigating and searching and exploring a collection of objects includes a database of Attributes; each of the Attributes being associated with one or more objects, and a database of Kinds, each Kind being associated with one or more Attributes. When a user enters a search query including at least one Attribute, an object is tested to determine whether it has Attributes of the Kind corresponding to the Kind of the at least one specified Attribute before function testing is performed. Search and contents investigation results are presented in a hierarchical format in which Kinds and Attributes rather than objects, are displayed until the search or content type is further specified by selecting additional Kinds and/or Attributes such that the number of objects satisfying the specified search is below a threshold. User interaction modifies the hierarchical order of Kinds and Attributes in the display.
