Patent number: 8433987Abstract: Embodiments of the invention provide a method of de-rate matching without NULL bits skipping. Date is received without NULLs and inputted into a LLR combining block. The history data without NULLs is buffered. Log-likelihood ratio (LLR) combining is called before de-rate matching. The output of LLR combining is de-interleaved. The reading pointer is offset to forge NULLs. Finally, de-interleaving output without NULLs is sent to a turbo decoder.Type: GrantFiled: August 27, 2010Date of Patent: April 30, 2013Assignee: Texas Instruments IncorporatedInventors: Wei Fan, Weifeng Li, Jiajun Zhang

Patent number: 8332763Abstract: Methods, systems, and computer-readable media that allow a user to select and add subsections of multiple websites to a single aggregated website that will automatically retrieve updated content corresponding to the selected subsection are provided. The content from the selected subsections may be displayed on the aggregated website. The aggregated website will periodically check a source website and update the content displayed on the aggregated site if the source website has been updated. The application generating the source website determines which subsection of the updated website corresponds with the subsection originally selected for display by comparing the document object model (“DOM”) for both the updated web page and the original version of the web page at the time the subsection selection was made by the user. Condensed DOM trees may be generated for the updated web page and the original version of the web page, prior to comparing the two DOM trees.Type: GrantFiled: June 9, 2009Date of Patent: December 11, 2012Assignee: Microsoft CorporationInventors: Jiajun Zhang, Yin Liu, Shenhua Gu
