H04Q 11/00

US Classification:

37920201, 379158, 370260, 455416

Abstract:

A method and apparatus for performing active speaker selection in teleconferencing applications illustratively comprises a microphone array module, a speaker recognition system, a user interface, and a speech signal selection module. The microphone array module separates the speech signal from each active speaker from those of other active speakers, providing a plurality of individual speaker's speech signals. The speaker recognition system identifies each currently active speaker using conventional speaker recognition/identification techniques. These identities are then transmitted to a remote teleconferencing location for display to remote participants via a user interface. The remote participants may then select one of the identified speakers, and the speech signal selection module then selects for transmission the speech signal associated with the selected identified speaker, thereby enabling the participants at the remote location to listen to the selected speaker and neglect the speech from other active speakers.

Abstract:

A telestration system comprises a telestration server configured to communicate with an arbitrary number of telestration clients over a network. The telestration server is further configured to receive telestration input signals from respective ones of the clients and to send telestration output signals to the respective clients, with the telestration output signal sent to a given one of the clients comprising telestration information derived from the telestration input signal received from at least one other one of the clients. Each of the clients with the support of the telestration server can generate a combined telestration overlay for presentation with associated visual content shared between the clients.

International Classification:

G01M 5/00
B23K 31/12

Abstract:

The present invention relates to nonlinear Vibro-Acoustic Modulation (VAM), one of the prevailing nonlinear methods for material characterization and structural damage evaluation. An algorithm of AM/FM separation is presented specifically for VAM method. While the commonly used Hilbert transform (HT) separation may not work for a typical VAM scenario, the developed IQHS and SPHS algorithms address HT shortcomings. They have been tested both numerically and experimentally (for fatigue cracks evolution) showing FM dominance at the initial micro-crack growth stages and transition to AM during macro-crack formation. In addition, the SPHS algorithm is capable of detecting fatigue crack via monitoring of modulation phase.

Abstract:

Systems and methods for training neural networks. One embodiment is a system that includes a memory configured to store samples of training data for a Deep Neural Network (DNN), and a distributor. The distributor identifies a plurality of work servers provisioned for training the DNN by processing the samples via a model of the DNN, receives information indicating Graphics Processing Unit (GPU) processing powers at the work servers, determines differences in the GPU processing powers between the work servers based on the information, and allocates the samples among the work servers based on the differences.

Abstract:

An external capability for measuring roundtrip latency in a conferencing system is provided. The external capability for measuring roundtrip latency in a communication system may include functions of generating a content event, detecting the content event in a received content stream including the content event, determine a first time associated with generation of the content event and a second time associated with detection of the content event, and computing a roundtrip latency based on a difference between the second time and the first time. The content event may be a visual event or an aural event. These functions may be implemented using one or more modules or elements. A computing device may be used to generate and detect the content event and to compute the roundtrip latency. Various other arrangements of modules or elements may be used to provide the functions.
