Publication number: 20240040043Abstract: Disclosed is a method for managing acoustic feedback in real-time audio communications in a communications system, the method comprising determining, by means of a detection module, whether a first communication device is in loudspeaker mode, whether the first communication device is in real-time audio communications with a second communication, and whether the first communication device and the second communication device are in a same acoustic space. Upon determining that this is the case a request signal for requesting one or more measures against acoustic feedback is provided to a mitigation module. Further disclosed are a device and a system configured to perform the method, a non-transitory computer-readable medium, an encoder and a decoder.Type: ApplicationFiled: December 22, 2021Publication date: February 1, 2024Applicant: Dolby Laboratories Licensing CorporationInventors: Qianqian FANG, Kai LI, Yanmeng GUO, Wei HUANG, Yang LIU

Patent number: 11677879Abstract: Some disclosed teleconferencing methods may involve detecting a howl state during a teleconference. The teleconference may involve two or more teleconference client locations and a teleconference server. The teleconference server may be configured for providing full-duplex audio connectivity between the teleconference client locations. The howl state may be a state of acoustic feedback involving two or more teleconference devices in a teleconference client location. Detecting the howl state may involve an analysis of both spectral and temporal characteristics of teleconference audio data.

Publication number: 20220383889Abstract: A method is disclosed herein for adapting parameters of a sibilance detector. Time-frequency features are extracted from an audio signal being received and. Based on those time-frequency features, a determination is made of whether the audio signal includes a short-term feature or a long-term feature. In accordance with determining that the audio signal includes the short-term feature or the long-term feature, one or more parameters of a sibilance detector for detecting sibilance in the audio signal are adapted. Sibilance in the audio signal, is detected using the sibilance detector with the one or more adapted parameters.Type: ApplicationFiled: July 16, 2020Publication date: December 1, 2022Applicant: Dolby Laboratories Licensing CorporationInventors: Yuanxing Ma, Kai Li, Qianqian Fang

Patent number: 11246529Abstract: A detector and inclusion location method that uses a reconstruction technique to target and localize sparse small-sized but high-contrast objects, such as a tumor inside tissue. The reconstruction technique applied, can dramatically enhance the property contrast of the tumors or abnormal inclusions by ten to one hundred fold. The reconstruction technique enables the use of nonlinear imaging ill-posed techniques that are function-oriented imaging techniques without any need for structural prior knowledge.Type: GrantFiled: July 15, 2019Date of Patent: February 15, 2022Assignee: Northeastern UniversityInventor: Qianqian Fang

Publication number: 20150078642Abstract: Method for providing external response based on changes in physiological status of biological sample determined by co-registration of sample images acquired in near-infrared and visible light, optionally by the user himself with a camera of a cell-phone cooperated with the data-processing unit. The NIR and visible image data are spatially co-registered with respect to spatial reference points associated with positions and orientations of camera to spatially coordinate the NIR and visible light images. Three-dimensional surface representing a sample's shape is determined based on stereo analysis of the first data. The NIR data is mapped onto such surface based on established spatial correlation to generate a topographic image representing the subsurface ROI and conforming to the sample's surface at multiple locations.Type: ApplicationFiled: April 23, 2013Publication date: March 19, 2015Inventor: Qianqian Fang

Patent number: 7825667Abstract: A microwave imaging process, and a system controlled by an associated software product, illuminate a target with microwaves from a transmitting antenna. Receiving antennas receive microwaves scattered by the target, and form microwave data. The illumination and receiving repeat over multiple transmitting antennas and multiple microwave frequencies. The microwave data is processed to form permittivity and conductivity images by selecting a background dispersion model for permittivity and conductivity. Permittivity and conductivity dispersion coefficients are determined, and permittivity and conductivity distributions are calculated, for each of the microwave frequencies. Forward solutions at multiple frequencies are determined from property distributions, and a dispersion coefficient based Jacobian matrix is determined. Dispersion coefficient updates are determined using the microwave data, and the dispersion coefficients are updated.Type: GrantFiled: December 21, 2005Date of Patent: November 2, 2010Assignee: Microwave Imaging Systems Technologies, Inc.Inventors: Qianqian Fang, Paul M.
