Patent number: 11386916Abstract: An apparatus and a method for acoustic scene classification of a block of audio samples are provided. The block is partitioned into frames in the time domain. For each respective frame of a plurality of frames of the block, a change measure between the respective frame and a preceding frame of the block is calculated. The respective frame is assigned, based on the calculated change measure, to one of a set of short-event frames, a set of long-event frames, and a set of background frames. The feature vector is determined based on a feature computed from one or more of the set of short-event frames, the set of long-event frames, and the set of background frames.Type: GrantFiled: May 4, 2020Date of Patent: July 12, 2022Assignee: Huawei Technologies Co., Ltd.Inventors: Milos Markovic, Florian Eyben, Andrea Crespi, Björn Schuller

Patent number: 10916255Abstract: An input audio signal comprises a plurality of input audio channels. A KLT-based pre-processor transforms the plurality of input audio channels into a plurality of eigenchannels and provides metadata associated with the plurality of eigenchannels. Each eigenchannel is associated with an eigenvalue and an eigenvector. The metadata allows reconstructing the plurality of input audio channels on the basis of the plurality of eigenchannels. A selector selects a subset of the plurality of eigenvectors corresponding to a plurality of selected eigenchannels on the basis of a geometric mean of the eigenvalues. An eigenchannel encoder encodes the plurality of selected eigenchannels. A metadata encoder encodes the metadata.Type: GrantFiled: December 21, 2018Date of Patent: February 9, 2021Assignee: Huawei Technologies Duesseldorf GmbHInventors: Panji Setiawan, Milos Markovic

Patent number: 10665248Abstract: A device having an input that is configured to receive a sound signal captured from an acoustic environment where the device is located, is provided. The device also includes a signal processor that is configured to obtain a reverberation signature from the sound signal and classify the acoustic environment as being of a particular type in dependence on that reverberation signature. It also includes a controller configured to control an operation of the device in dependence on the classification of the acoustic environment. By using the reverberation signature to classify the environment, the device it is not dependent on a particular type of signal having to be present in the environment at the time when the sound signal is captured. The reverberation properties of the environment will be embodied by any sound signal captured from that environment.Type: GrantFiled: March 8, 2019Date of Patent: May 26, 2020Assignee: Huawei Technologies Co., Ltd.Inventors: Milos Markovic, Jürgen Geiger

Publication number: 20160109284Abstract: The invention provides a method for generating an output indicative of acoustical sound transmission in a room. By using e.g. a point cloud representation of an acoustic environment, it is possible to calculate its acoustics from the interior information obtained from the depth camera. This approach is suitable e.g. for run-time applications since it is not based on an audible excitation that can disturb running audio. Also, the point-cloud model can be updated in real time according to the scene changes detected by depth-camera. This allows efficient acoustical simulation of dynamic, interactive environments. Although only geometrical information of a room is provided, high amount of surface details leaves possibility for implementation of material recognition algorithms that involve semantic mapping. This can provide information of reflective properties of surfaces or objects at a point level. Also, a high amount of details allows a good approximation of complex geometries, e.g.Type: ApplicationFiled: March 18, 2014Publication date: April 21, 2016Inventors: Dorte Hammershøi, Søren Krarup Olesen, Milos Markovic

Patent number: 8240371Abstract: A multi-function sub is connected between a top drive of a drilling rig and a casing gripper. The sub has telescoping upper and lower members that rotate with each other. A sleeve is mounted to one of the members. That sleeve is prevented from rotation with the upper and lower members by an anti-rotation device. A piston is located on the other member and reciprocally carried within the sleeve. An external pump is connected to the sleeve for supplying pressurized fluid into the sleeve to act against the piston. This fluid provides compensation for thread makeup when a new joint of casing is being secured to a string of casing.Type: GrantFiled: June 15, 2009Date of Patent: August 14, 2012Assignee: Tesco CorporationInventors: Radovan Tepavac, Milo Markovic
