Patent number: 11564038Abstract: An audio system includes an equatorial acoustic sensor array (EASA) that may be coupled to an object. The audio system is configured to detect, via the EASA, signals corresponding to a portion of a sound field in a local area. The detected signals are converted into a plurality of corresponding abstract representations that describe the portion of the sound field. Effects of scattering of the object are removed from the abstract representations to create adjusted abstract representations. A set of spherical harmonic (SH) coefficients is determined using the adjusted abstract representations. The set of SH coefficients describe an entirety of the sound field. And the set of SH coefficients and head related transfer functions of a user are used for binaural rendering of the reconstructed sound field to the user.Type: GrantFiled: March 19, 2021Date of Patent: January 24, 2023Assignee: Meta Platforms Technologies, LLCInventors: Jens Ahrens, Hannes Helmholz, David Lou Alon, Sebastià Vicenç Amengual Garí

Patent number: 10313818Abstract: The derivation of personalized HRTFs for a human subject based on the anthropometric feature parameters of the human subject involves obtaining multiple anthropometric feature parameters and multiple HRTFs of multiple training subjects. Subsequently, multiple anthropometric feature parameters of a human subject are acquired. A representation of the statistical relationship between the plurality of anthropometric feature parameters of the human subject and a subset of the multiple anthropometric feature parameters belonging to the plurality of training subjects is determined. The representation of the statistical relationship is then applied to the multiple HRTFs of the plurality of training subjects to obtain a set of personalized HRTFs for the human subject.Type: GrantFiled: January 22, 2018Date of Patent: June 4, 2019Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Piotr Tadeusz Bilinski, Jens Ahrens, Mark R. P. Thomas, Ivan J. Tashev, John C. Platt, David E. Johnston

Patent number: 8474285Abstract: In the process a glass tube line is drawn from a glass tube production plant and the glass tube is severed from the glass tube line. At the same time the still heated glass tube is subjected to a selective local heat treatment of the at least one tube end section prior to cooling down completely in order to reduce the stresses in the respective tube end section. Not the entire glass tube but instead only the respective tube end section is subjected to the selective local heat treatment. The heat treatment is performed in particular in such a manner that the mechanical tensile stress in the region between 7 mm and 20 mm from the tube end or ends is reduced to below 6.0 MPa, more preferably to below 4.5 MPa.Type: GrantFiled: July 2, 2010Date of Patent: July 2, 2013Assignee: Schott AGInventors: Reiner Bartsch, Jens Ahrens, Markus Pappenberger, Roland Fuchs
