Patent number: 11025283Abstract: Techniques are described for improving the decoding latency and throughput of an error correction system that includes multiple decoders. For example, the error correction system intelligently distributes and balances the decoding of codewords between the different decoders. In particular, the error correction system can consider different factors associated with decoding various codewords including, for instance, the checksum of a codeword that is to be decoded, an estimated number of decoding iterations to decode the codeword by a decoder based on the checksum, and/or an accumulated number of decoding iterations for decoding by the decoder of the codeword in addition to other codewords already buffered for the decoder. Given these factors, the error correction system can generate a decision to decode the codeword by the decoder or by another decoder of the error correction system, where the decision optimizes the performance.Type: GrantFiled: February 26, 2020Date of Patent: June 1, 2021Assignee: SK hynix, inc.Inventors: Xuanxuan Lu, Fan Zhang, ShiangJyh Steve Chang, Aman Bhatia

Patent number: 10009298Abstract: A communication application displays a modality view that may be one of a collaboration, a gallery, or a messaging view on a conversation canvas. The application may display an initial view according a modality selection by the user. A user is enabled to select a next view from the set by providing a user action such as a tap, swipe action, etc. The application dynamically generates the next modality view according to the initial view. Common participants and common contexts are used to configure the next view. Subsequent to configuration, the application displays the next modality view on the conversation canvas by transitioning from the initial view. The application retains session information from the initial view to restore the initial view session if the user selects to return to the initial view.Type: GrantFiled: June 5, 2015Date of Patent: June 26, 2018Assignee: Microsoft Technology Licensing, LLCInventors: Nathan Gunderson, Alexander Darrow, Zhaoqing Ma, Punit Java, Christina Marie Meyer, Steve Chang, Leslie Cindy Chen, Eric Hamilton, Marcelo Truffat

Patent number: 9111233Abstract: A computing device learns over time how to identify task reminders that are most likely to be helpful to a user in different contexts. The task reminders can remind the user of activities that the user needs to do. The computing device displays a graphical user interface (GUI) that contains the task reminders identified as being most likely to be helpful to the user in the user's current context. The computing device updates the task reminders in the GUI as the user's context changes. In this way, the computing device can present task reminders that are likely to be currently helpful to the user while suppressing task reminders that are less likely to be helpful to the user at the current time.Type: GrantFiled: June 30, 2014Date of Patent: August 18, 2015Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Arulkumar Elumalai, Thomas Bouchard, Steve Chang, Eran Shtiegman, Aaron Tinling
