  • Patent number: 7721205
    Abstract: A graphical object is generated according to a first application in a document of a second application. The graphical object is constructed as a composite, data-driven object. The graphical object's data is organized so that the semantic data (e.g., relationship among individuals on an organizational chart) is persisted separately from presentation data (e.g., the layout and style of shapes and connectors for visualizing the organizational chart). The semantic data and presentation data are combined to provide the rendered view of the graphical object within the document. The graphical object displays and functions equivalently to when the graphical object is rendered by the first application.

  • Publication number: 20100115350
    Abstract: Novel, computationally efficient schemes for deterministic wavelet thresholding with the objective of optimizing maximum-error metrics are provided. An optimal low polynomial-time algorithm for one-dimensional wavelet thresholding based on a new dynamic-programming (DP) formulation is provided that can be employed to minimize the maximum relative or absolute error in the data reconstruction. Directly extending a one-dimensional DP algorithm to multi-dimensional wavelets results in a super-exponential increase in time complexity with the data dimensionality. Thus, novel, polynomial-time approximation schemes (with tunable approximation guarantees for the target maximum-error metric) for deterministic wavelet thresholding in multiple dimensions are also provided.

  • Publication number: 20100106914
    Abstract: Systems and methods that designate read/write consistency models based on requirements of a distributed store to increase performance or scale. Such sever loads can be determined via a plurality of mechanisms, including delays in responses by the primary node; setting predetermined threshold limits that if exceeded results in contacting secondary nodes; polling services of the distributed cache periodically and maintaining track of loads on the servers, and the like. The weak or scalable read can occur when read requests are directed to a secondary node, and upon over loading of the primary node.

  • Publication number: 20100073207
    Abstract: Delta-sigma analog-to-digital converters (ADCs) and methods to calibrate methods to delta-sigma ADCs are disclosed. In one particular example, a delta-sigma ADC is described, including an n-bit feedback digital-to-analog converter (DAC) having a number of unit elements, and is configured to provide a feedback signal to a summing device, which generates a difference signal based on an analog input signal and the feedback signal. An n-bit ADC is included to generate an n-bit digital signal based on the difference signal. A dynamic element matching device selects one or more unit elements in the DAC based on the n-bit digital signal. A storage device, such as a memory, stores error coefficients corresponding to the plurality of unit elements. Finally, a digital corrector is included to receive the selection of unit elements, receive error coefficients corresponding to the selected unit elements, and adjust the n-bit digital signal based on the received error coefficients.

  • Patent number: 7668856
    Abstract: The invention provides methods and systems for summarizing multiple continuous update streams such that an approximate answer to a query over one or more of the continuous update streams (such as a Query requiring a join operation followed by a duplicate elimination step) may be rapidly provided. The systems and methods use multiple (parallel) Join Distinct (JD) Sketch data structures corresponding to hash buckets of at least one initial attribute.

  • Patent number: 7663511
    Abstract: In one embodiment, a computing device may compress a text file for storage by dynamically creating an encoding table. A storage device of the computing device may store an encoding table populated by string characters from a text file. A processor of the computing device may encode the text file by replacing a string character in a text string of the text file with a table index position of that string character in the encoding table. The processor of the computing device may decode the text file by replacing the table index position with the string character at the table index position in the encoding table.

  • Publication number: 20100003024
    Abstract: A camera includes a lens and a sensor. A dynamic mask is arranged at an aperture plane between the lens and the sensor, and a static mask is arranged immediately adjacent to the sensor. Angular, temporal or spatial variations in light rays acquired of a scene by the sensor are mapped to individual pixels of the sensor.

  • Publication number: 20090292674
    Abstract: Disclosed are apparatus and methods for facilitating search queries via a computer network. In certain embodiments, each search term that a user inputs for a search query causes a rich set of contextual information having one or more parameters or facets to be presented to the user to further enhance and refine the search query. The context facets can pertain to the search term itself or contextual information that is associated with search results objects that have been previously associated with such search term. Additionally, the user can be queried for a facet to be associated with the search term. The user can then input parameter values or choose selection option (e.g., numbers, strings, links, etc.) for each facet, and search results can then be provided based on such facet parameter values or selection option input.
