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: 9488778Abstract: A method for realizing an optical waveguide in a substrate by means of a femtosecond laser system, the waveguide including a birefringence axis tilted by a predetermined angle for at least a segment, is disclosed. The method includes preparing a substrate including a free surface, focusing a femtosecond laser beam into the substrate, in order to induce a refractive index modification of a volume of such substrate around the focal region. The method further includes varying a propagation direction of the femtosecond laser beam to reach a propagation direction describing a predetermined non-vanishing angle with respect to the normal to the free surface of the substrate, and translating the focal region with respect to the substrate, in order to generate the waveguide segment.Type: GrantFiled: April 18, 2014Date of Patent: November 8, 2016Assignees: CONSIGLIO NAZIONALE DELLE RICERCHE, SAPIENZA UNIVERSITA' DI ROMAInventors: Roberto Osellame, Andrea Crespi, Giacomo Corrielli, Fabio Sciarrino
