Publication number: 20240098438Abstract: The present invention is directed to methods and apparatus for translating a first plurality of audio input channels to a second plurality of audio output channels. This includes determining that there is pair-wise coding among any of the first plurality of audio input channels, determining an input/output-mapping matrix for mapping at least a first set of the first plurality of audio input channels to at least a second set of the second plurality of audio output channels; and deriving the second plurality of audio output channels based on first plurality of audio input channels, the input/output-mapping matrix and the determined pair-wise coding. The first plurality of audio input channels represent the same soundfield represented by the second plurality of audio output channels.Type: ApplicationFiled: September 25, 2023Publication date: March 21, 2024Applicant: Dolby Laboratories Licensing CorporationInventor: Mark F.

Patent number: 11900470Abstract: A first inspection of insured property is performed to detect hazardous conditions related to the insured property. This first inspection is performed using a first set of imagery data received from one or more imagery data sources. One or more preventive measures are recommended to address the detected hazardous conditions based on analysis of the first set of imagery data. A second inspection is performed using a second set of imagery data received from the imagery data sources. The second inspection is performed to verify that recommended preventive measures have been taken. The first and second sets of imagery data may contain satellite and aerial imagery. The imagery data sources may provide information such as an image of an insured property's roof, an image of a terrain surrounding the insured property, or any other aerial images.Type: GrantFiled: March 9, 2021Date of Patent: February 13, 2024Assignee: United Services Automobile Association (USAA)Inventors: Ramsey Devereaux, Tearanie Kennedy, Michael J.

Publication number: 20230091218Abstract: A system and method of modifying a binaural signal using headtracking information. The system calculates a delay, a first filter response, and a second filter response, and applies these to the left and right components of the binaural signal according to the headtracking information. The system may also apply headtracking to parametric binaural signals. In this manner, headtracking may be applied to pre-rendered binaural audio.Type: ApplicationFiled: November 30, 2022Publication date: March 23, 2023Inventors: C.

Patent number: 11308969Abstract: A method performed in an audio decoder for decoding M encoded audio channels representing N audio channels is disclosed. The method includes receiving a bitstream containing the M encoded audio channels and a set of spatial parameters, decoding the M encoded audio channels, and extracting the set of spatial parameters from the bitstream. The method also includes analyzing the M audio channels to detect a location of a transient, decorrelating the M audio channels, and deriving N audio channels from the M audio channels and the set of spatial parameters. A first decorrelation technique is applied to a first subset of each audio channel and a second decorrelation technique is applied to a second subset of each audio channel. The first decorrelation technique represents a first mode of operation of a decorrelator, and the second decorrelation technique represents a second mode of operation of the decorrelator.Type: GrantFiled: October 5, 2020Date of Patent: April 19, 2022Assignee: Dolby Laboratories Licensing CorporationInventor: Mark F.

Patent number: 11269151Abstract: An enclosure includes a base and at least three members joined to the base, each member having inner and outer walls and extending upward from the base to form at least a first opening and a second opening along an outer surface formed by the outer walls of the members and an interior space bounded by the inner walls, where the first opening and the second opening are wide enough to accommodate one or more cables routed from the first opening to the second opening along the inner wall of the member positioned between the first opening and the second opening, and where the inner wall positioned between the first opening and the second opening has a radius of curvature that prevents a cable routed from the first opening to the second opening along the inner wall from bending beyond a minimum bend radius.Type: GrantFiled: September 10, 2018Date of Patent: March 8, 2022Assignee: FTTX Technology Advisors, LLCInventor: Mark F.
