Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, determining that a voting user interface (VUI) is to be provided with search results, the VUI enabling a user to submit one or more votes in a voting-based campaign; receiving social content, the social content having been distributed using one or more social networking services; receiving search results that are responsive to a search query; and transmitting instructions to display the search results and the VUI, the VUI comprising the social content.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for resolving keystrokes input into an electronic device. One of the methods includes receiving multiple keystrokes in the electronic device. Multiple characters that correspond to the multiple keystrokes are stored in a storage location for a predetermined time interval. In response to the predetermined time interval elapsing, the characters that correspond to the multiple keystrokes are reordered with respect to each other based on a statistical model.

Abstract: Methods and systems for spatially aware sub-pixel rendering are described herein. Embodiments allow graphics rendering systems to convey additional spatial information in displayed graphics by utilizing sub-pixels of displays. An embodiment includes sampling pixels into a buffer, re-sampling the pixels, at sub-pixel level, at different offset positions from their positions in the buffer and displaying the re-sampled pixels. For example, individual red, green and blue sub-pixels can be re-sampled at offset positions from their original positions within pixels. Since embodiments of the invention can control respective positions of each red, green and blue sub-pixel, embodiments can produce sharp graphics with low aliasing. Furthermore, sub-pixels are effectively used for communicating additional spatial information in rendered graphics.

Abstract: A system (and a method) are disclosed for optimizing lossless data compression in digital images systems iteratively. The system includes a backward reference module and an entropy encoder. The backward reference module comprises three sub-modules: a backward reference selection module, a backward reference statistics measurement module and a backward reference selection control module. The backward reference selection module initially selects backward references that have shorter backward distances. The statistics measurement module analyzes the backward references of input data. The backward reference selection module updates the backward references based on the statistics of previously generated backward references at subsequent selection iterations. The backward reference selection control module controls the number of selection iterations needed for optimized data compression performance.

Abstract: A system (and a method) are disclosed for optimizing lossless data compression in digital images systems. The system includes an optimized backward reference selection module and an entropy encoder. The optimized backward reference selection module selects the backward references that the backward reference distances and/or lengths are an integer multiple of size of data elements. The optimized backward reference selection module further compacts the entropy code of the backward references by favoring backward references that have the intrinsic locality of source data stream. The optimization offered by the backward reference selection module allows an improved compression ratio and faster compression speed for lossless image compression.
