  • Patent number: 10120401
    Abstract: A system for power grid distribution network control can monitor a power grid distribution network in real-time, detect an abnormal loading condition based on real-time measurements on the distribution network, and perform in real time, in response to the detected abnormal loading condition, a reconfiguration analysis of the distribution network. The reconfiguration analysis can be performed based on heuristic logic that combines real time depth first trace and breadth first division of nodes within the distribution system. Through the reconfiguration analysis process, the system can generate and implement a practical and optimized reconfiguration plan in real time so as to alleviate or eliminate an abnormal loading condition in time to prevent possible pre-matured failures of equipment and consequently save cost of equipment replacement and/or related power outages. Accordingly, the distribution network may operate with improved stability and reliability, and a cost of operation can be reduced.

  • Patent number: 8659620
    Abstract: To facilitate rendering an image, e.g., a portion of a PDF page, at higher resolutions or locations than could be expressed using standard 32 bit fixed point integer values, an image is segmented and a user space coordinate system origin used for individual segment processing is transformed on a per segment basis to each segment locality before a render request is made to a rendering function library. After a new origin of a segment is established, the PDF page content contained within that locality corresponding to the individual segment being processed is rendered, e.g., using functions available in the PDF software library. The results of processing the segments is combined to produce a final high-resolution image. While the input to the rendering process may include values which can not be expressed in 32 bit fixed point notation, the segmentation process allows the individual segments to be rendered using rendering specified using such notation.

A matrix-structured knowledge base with five distinct rule bases is used. The line section and bus tables must be updated after any switching operations are enacted. Extensive simulations of the knowledge-based system revealed that a solution was found in a time-efficient manner. This knowledge-based system enhances network reliability and hence prevents power outages.

  • Patent number: 7973799
    Abstract: In a technique for rendering non-linear BRDFs that are stable in both the temporal and spatial domains, without serious interruption to the content creation pipeline used in most games, non-linear content is linearized by rendering in texture space at a fixed resolution. A MIP-map chain is calculated from this texture. The complete MIP-map chain is used for rendering on a display device. Low resolution reflectance parameters are used to approximate the highest resolution reflectance parameters as the object becomes smaller on the display device. The low resolution reflectance parameters are calculated using non linear fitting techniques.

  • Patent number: 7911487
    Abstract: Sub-pixel rendering with gamma adjustment allows the luminance of the sub-pixel arrangement to match the non-linear gamma response of the human eye's luminance channel. For each of a subset of input sampled data indicating a region of an input image, a gamma-adjusted data value is generated for each input image data value in the subset using a local average of at least two input image data values. A sub-pixel rendering operation uses the subset of gamma-adjusted data values and the subset of input image data values to produce an output data value for each sub-pixel element on the display panel. A plurality of output data values collectively indicates an output image. The gamma adjustment allows the sub-pixel rendering to operate independently of the actual gamma of a display device. The sub-pixel rendering techniques with gamma adjustment may improve image contrast in high spatial frequency portions of an image.

  • Patent number: 7901095
    Abstract: A projection system uses a transformation matrix to transform a projection image p in such a manner so as to compensate for surface irregularities on a projection surface. The transformation matrix makes use of properties of light transport relating a projector to a camera. If the resolution a camera is lower than that of a projector within said projection system, then the transformation matrix will have holes where image data corresponding to a projector pixel will have been lost. In this, case, new image are generated to fill-in the holes.

  • Patent number: 7742058
    Abstract: An output color profile, such as an ICC output profile, contains a look-up table to separate the color of a pixel, for example a CIELAB color, into a set of colorant values, for example CMYK colorants. In practice, most CMYK images have been separated using one of a limited set of standardized output profiles. The problem to be solved is guessing which one of these standardized output profiles has been used to separate a specific image. For this purpose the CMYK values of the image are analyzed. The analysis involves calculating a distance in the CMYK space between the CMYK values of an image, and the CMYK values produced by different output profiles. A profile is selected based on these distances, for example by selecting the profile yielding the shortest distance. This profile is then used for converting the CMYK colorant values of the image into CIELAB color values.

  • Patent number: 7683917
    Abstract: Methods and products are disclosed concerning extraction of selected components of a warping of an image. Given a warped image and a distortion grid, the distortion at any point in the image may be viewed locally as a displacement and a linear transform. The linear transform can be manipulated to extract elements of the local distortion such as skew, rotation, magnification and combinations. The selected components may then be selectively applied at other locations of the same or a different image, using a variety of virtual paintbrushes for different effects.

  • Patent number: 7639372
    Abstract: A scanning system includes one or more stereo camera sets (10) for detecting qualitative and quantitative anomalies of an object (40). Each stereo camera set (10) includes two cameras (12, 14) and a projector (16). Each camera (12, 14) is calibrated to correct any distortion due to misalignment of the CCD matrix array (18) and deficiencies of the optical system. The projector (16) projects an absolute encoded pattern (32, 34, 36) onto the object (40) to be measured and is capable of varying the intensity of the emitted electromagnetic energy in the infrared, visible and ultraviolet spectrums. A plurality of camera sets (10) can be combined in a scanning system matrix (42, 44) capable of detecting anomalies of the object (40) in a three-dimensional room (26). The three-dimensional room (26) can be of any desirable size, depending on the number of stereo camera sets (10).

  • Patent number: 7626589
    Abstract: The invention provides techniques for wrapping a two-dimensional texture conformally onto a surface of a three dimensional virtual object within an arbitrarily-shaped, user-defined region. The techniques provide minimum distortion and allow interactive manipulation of the mapped texture. The techniques feature an energy minimization scheme in which distances between points on the surface of the three-dimensional virtual object serve as set lengths for springs connecting points of a planar mesh. The planar mesh is adjusted to minimize spring energy, and then used to define a patch upon which a two-dimensional texture is superimposed. Points on the surface of the virtual object are then mapped to corresponding points of the texture. The invention also features a haptic/graphical user interface element that allows a user to interactively and intuitively adjust texture mapped within the arbitrary, user-defined region.
