  • Publication number: 20100074550
    Abstract: Current generation digital media processors support multi-format video resolutions, SDTV, Progressive Scan and HDTV. Built-in video encoders directly support NTSC and progressive 480 P video outputs. These two video formats have different image bandwidth and output gain requirements, but are normally filtered by fixed bandwidth filters. This invention provides adjustable filter bandwidth for improved video filtering and solves the dilemma on filter bandwidth design for multi-format video applications. The invention is applicable to video reconstruction filter applications requiring bandwidth adjustable filters.

  • Publication number: 20090049209
    Abstract: This invention is a method allowing for interfacing high speed hard disk drives (ATA-HDD) in high throughput PIO modes to currently available digital media processors (DMP). The prescribed interface programs signals available in the DMP external memory interface (EMIF) functions to match the requirements of ATA-HDD PIO functions. Selected signal redefinition and minimal glue logic is employed to form a seamless link between the EMIF I/O of the digital media processor DMP and the ATA-HDD hard drive.

  • Publication number: 20080177710
    Abstract: Vectors representing objects in n-dimensional space are approximated by local polar coordinates on partitioned cells of the data space in response to a query, e.g., a query data vector entered with a request to find “k” nearest neighbors to the query vector. A set of candidate near neighbors is generated using the approximations, with the local polar coordinates being independent of the dimensionality of the data space. Then, an answer set of near neighbors is returned in response to the query. Thus, the present invention acts as a filter to reduce the number of actual data vectors in the data set that must be considered in responding to the query.

  • Publication number: 20070098051
    Abstract: A rake receiver finger assignor is configured to assign a rake receiver finger to a time offset between identified signal path time offsets in accordance with a concentration of identified signal paths from a transmitter to a rake receiver. In accordance with the exemplary embodiment, a number of identified signal paths having time offsets within a time window are observed to determine the concentration of signal paths identified by a path searcher. If the number of identified signal paths indicates a concentrated distribution of signal paths such as during a fat path condition, at least one rake finger is assigned between at a time offset between two identified signal paths.

  • Patent number: 6892181
    Abstract: A system and method for improving the effectiveness of web advertising by allowing a user to return and request a previously displayed ad that appeals to the user. Generally, the system employs an intelligent browser cache maintained within a user's terminal to keep web pages in cache and maintain information about hyperlinks contained therein. Furthermore, the system allows for the storing of ads in a bookmark memory without clicking on the ads. The bookmark memory is either permanently maintained or temporarily stored for a predetermined time period at the user's terminal to allow the user view all the stored ads at a later time. The system further includes an algorithm for computing the differences between previously visited pages stored in the intelligent browser cache and a new page in terms of their hyperlinks.

  • Patent number: 6661465
    Abstract: An interface (10) for connecting a calculator (12) to a standard television (11), so that the calculator's display can be re-displayed on the television (1). The interface (10) is useful with different calculators having different display formats. Reformatting of the input signal is accomplished by dividing format detection and reformatting tasks between a field programmable gate array (21) and a microprocessor (23).

  • Patent number: 6658642
    Abstract: A system, method and program product for computer program development. A new computer program to be developed is outlined and the outline organized to identify required modules. Required modules are provided to the system, which categorizes them and posts a list of required modules with corresponding requirements on, for example, a dedicated web site. Module requirements may include module specifications, a corresponding price and a deadline. Software developers intending to participate may provide an intention to submit. If fewer than two developers intend to submit module candidates for one or more required modules, the computer program outline may be reorganized to encourage more participants. For each required module where at least two module candidates are received, the candidates are tested for compliance with corresponding module requirements.
