Patent number: 9955425Abstract: Methods and devices may select a particular radio access technology (RATs) available on a multi-technology wireless communication device to support a user activity based on monitored device usage patterns and power consumption profiles of the various RATs. Various embodiments may enable multi-RAT wireless communication devices to monitor the usage patterns of each service (i.e., wireless communication link) provided by the device, and estimate the power consumption during the user activity based on the power needs of services and the user activity. A multi-RAT wireless communication device may determine whether switching, enabling, or disabling services and/or RATs would reduce power consumption. Thus, the wireless communication device may extend the time that a user can perform a user activity when battery reserves are low by switching to a lower-power RAT and/or disabling power-hungry services.Type: GrantFiled: October 21, 2015Date of Patent: April 24, 2018Assignee: QUALCOMM IncorporatedInventors: Sabyasachi Bhattacharya, Ajeet Kumar, Ajay Kumar Reddy Boddu

Patent number: 8761089Abstract: A method and system for acknowledging multiple frames in a communication network is provided. A receiver detects transmission of frames from a transmitter. The receiver determines a format for an acknowledgment frame comprising multiple bytes, from multiple frame acknowledgment formats for reporting status of reception of the frames by the receiver. The receiver reports the status of reception of the frames by encoding a distance between a number of frames between two successive correctly received frames, between two successive unsuccessfully received frames, between a correctly received frame and a successive unsuccessfully received frame, or between an unsuccessfully received frame and a successive correctly received frame, in the acknowledgment frame. One or more of the frame acknowledgment formats are configured to generate the acknowledgment frame for acknowledging the frames using a decreased number of bytes.Type: GrantFiled: December 5, 2011Date of Patent: June 24, 2014Assignee: Brillio, LLCInventor: Sabyasachi Bhattacharya

Patent number: 8095261Abstract: A system and method for enhancing vehicle diagnostic and prognostic algorithms and improving vehicle maintenance practices. The method includes collecting data from vehicle components, sub-systems and systems, and storing the collected data in a database. The collected and stored data can be from multiple sources for similar vehicles or similar components and can include various types of trouble codes and labor codes as well as other information, such as operational data and physics of failure data, which are fused together. The method generates classes for different vehicle components, sub-systems and systems, and builds feature extractors for each class using data mining techniques of the data stored in the database. The method also generates classifiers that classify the features for each class. The feature extractors and feature classifiers are used to determine when a fault condition has occurred for a vehicle component, sub-system or system.Type: GrantFiled: March 5, 2009Date of Patent: January 10, 2012Assignee: GM Global Technology Operations LLCInventors: Mark N.

Publication number: 20110015967Abstract: A method for temporal trend detection employing non-parametric techniques. A set of discrete data is provided and a rank is assigned to the data based on both sensitivity and severity of the data. The method statistically ranks the ranked data by categorizing the data in bins defined by an average positional ranking that identifies the severity of the data for each sensitivity category provided by a bin. The method then clusters the statistically ranked data that has been categorized by average positional ranking so as to detect changes in the data. Clustering the statistically ranked data can include using a multi-nominal hypothesis testing procedure. The method then identifies trends in the data based on the detected changes.Type: ApplicationFiled: July 17, 2009Publication date: January 20, 2011Applicant: GM GLOBAL TECHNOLOGY OPERATIONS, INC.Inventors: Sabyasachi Bhattacharya, Soumen De
