Abstract: Certain aspects of the present disclosure provide a technique for wireless communications by a user equipment (UE). The UE monitors a concurrent operation on multiple operating bands within a same subscriber identity module (SIM) or between multiple SIMs that involves sharing at least one radio frequency (RF) component. The UE enables or disables the at least one RF component based on the monitoring.

Abstract: A user equipment (UE) may monitor a channel for wireless communication associated with a first radio access technology (RAT) during one or more of a first active duration or a first inactive duration. The UE may operate in a first power mode during the first inactive duration. The UE may monitor the channel for wireless communication associated with a second RAT during one or more of a second active duration or a second inactive duration. The UE may operate during the second inactive duration in one or more of the first power mode or a second power. The UE may operate according to the first mode or the second mode based on the monitoring of the channel associated with the first RAT and the second RAT.

Abstract: Disclosed are systems and methods for generating a long-term signal level estimate during automatic gain control. In an example method, a computing device receives an input signal comprising feed data, the input signal derived from an upstream input signal. The computing device selects a first subset of the feed data and divides the first subset of the feed data into a plurality of analysis intervals. The computing device calculates a statistical average of each analysis interval and generates a first Gaussian distribution based on the statistical average of each analysis interval of the plurality of analysis intervals. Based on one or more characteristics of the first Gaussian distribution, the computing device determines the long-term signal level estimate, generates a first stage gain based on the long-term signal level estimate, and applies the first stage gain to the input signal.

Abstract: Disclosed are systems and methods for a frontend capture module of a video conferencing application, which can modify an input signal, received from a microphone device to match predetermined signal characteristics, such as voice signal level and expected noise floor. An Input stage, a suppression module and an output stage amplify the voice signal portion of the input signal and suppress the noise signal of input signal to predetermined ranges. The input stage selectively applies gains defined by a gain table, based on signal level of the input signal. The suppression module selectively applies a suppression gain to the input signal based on presence or absence of voice signal in the input signal. The output stage further amplifies the input signal in portions having a voice signal and applies a gain table to maintain a consistent noise floor.

Abstract: Disclosed are systems and methods for automatic control of gain in audio and video conferencing applications to maintain a predetermined and stable audio level. In one embodiment, a first stage applies a first stage gain based on a long-term estimate of signal level, while a second stage gain, based on a short-term estimate of signal level assists the first stage gain to achieve a target level. Some embodiments of long-term level estimation utilize statistical analysis of a buffer to validate or arrive at a more accurate long-term signal level estimate.

Abstract: A turbine blade structure for improving aerodynamic efficiency of low-pressure turbine blades, including: a suction side, a pressure side, multiple dimples and a blade body. The suction side is an outer convex side of the blade body. The pressure side is an inner concave side of the blade body. The dimples are arranged on the suction side in pairs. Each dimple forms an inclination angle ? with an air flow. The air flow includes a first fluid and a second fluid, and the energy of the first fluid is lower than that of the second fluid. Each dimple sucks the first fluid at a first end when the air flow passes a surface of the blade body, and allows the first fluid to spirally flow along an inclined direction in each dimple to form a spiral vortex, and discharge the first fluid through a second end.
