20150261596 | FRAMEWORK FOR USER-MODE CRASH REPORTING - A user-mode crash reporting system for generating a crash report when an application crashes is provided. The user-mode crash reporting system installs a crash handler to execute in the same process as the application when the application crashes. When the application crashes, the crash handler identifies a victim thread of the process that was executing at the time of a crash. The crash handler then walks a call stack of the victim thread to identify return addresses for returning from called functions of the application. The crash handler identifies offsets within the module corresponding to the return addresses and creates a call chain of functions using the identified offsets. The crash handler then generates a crash report based on the identified call chain. | 09-17-2015 |

20150032446 | METHOD AND SYSTEM FOR SIGNAL TRANSMISSION CONTROL - An audio signal with a temporal sequence of blocks or frames is received or accessed. Features are determined as characterizing aggregately the sequential audio blocks/frames that have been processed recently, relative to current time. The feature determination exceeds a specificity criterion and is delayed, relative to the recently processed audio blocks/frames. Voice activity indication is detected in the audio signal. VAD is based on a decision that exceeds a preset sensitivity threshold and is computed over a brief time period, relative to blocks/frames duration, and relates to current block/frame features. The VAD and the recent feature determination are combined with state related information, which is based on a history of previous feature determinations that are compiled from multiple features, determined over a time prior to the recent feature determination time period.
