摘要： 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.

摘要： Cell timing is detected by first trying to detect a target handover cell through detecting a primary synchronization channel (P-SCH) followed by a common pilot channel (CPICH). If that fails, N number of retrials is performed using a full-window search on the CPICH. The full-window CPICH search is performed blindly, without any slot timing information from the P-SCH. Performance is improved while maintaining the benefits of faster acquisition methods in good channel conditions. The full-window search is more time consuming, but takes advantage of the stronger CPICH transmission. In good channel conditions, a mobile device can proceed quickly with the normal method of timing acquisition. With failure, the mobile device can switch to the longer search which has a higher probability of successfully completing the hard handover procedure. The overall effect is a higher success rate of hard handovers without a uniform increase of time spent in cell timing acquisition.

摘要： 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.

摘要： Current generation digital media processors support multi-format video resolutions, SDTV, Progressive Scan and HDTV. Built-in video encoders directly support NTSC and progressive 480P 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.

摘要： 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.

摘要： 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. Presented to the user in separate windows are all the ads from both the old and new pages to aid the user in deciding whether to click and visit a different page or to save the displayed page for later use. Finally, the system permits the user to request for ads previously displayed at a particular position by pointing his mouse to the current ad at such a location.
