  • Patent number: 12562148
    Abstract: An expressive speech translation system may process source speech in a source language and output synthesized speech in a target language while retaining vocal performance characteristics such as intonation, emphasis, rhythm, style, and/or emotion. The system may receive a transcript of the source speech, translate it, and generate transcript data. To generate the synthesized speech, the system may process the transcript data with a language embedding representing language-dependent speech characteristics of the target language, a speaker embedding representing speaker-dependent voice identity characteristics of a speaker, and a performance embedding representing the vocal performance characteristics of the source speech. The system may control the duration of segments of the synthesized speech to better align with corresponding segments of the source speech for the purpose of dubbing multimedia content with synthesized speech in a language different from that of the original audio.

  • Publication number: 20240412450
    Abstract: Aspects presented herein relate to methods and devices for graphics processing including an apparatus, e.g., a GPU or CPU. The apparatus may obtain pixel information for a plurality of pixels in at least one frame included in a plurality of frames in a scene. The apparatus may also calculate a depth value for each of a first set of pixels. Further, the apparatus may identify whether each of the first set of pixels or a second set of pixels, or both, is occluded by at least one occluding object in the scene. The apparatus may configure a pattern mask configuration associated with a visibility mask for the plurality of pixels. The apparatus may also output, based on the pattern mask configuration, an indication of the depth value for the first set of pixels and coverage information for the first set of pixels or the second set of pixels.

  • Patent number: 8506846
    Abstract: A catalyst comprising a physical mixture of particles of a catalytic material and particles of char is provided. The catalyst can be used in various processes, including the reforming of tars present in syngas generated during biomass gasification. The catalyst is produced through a mechanical mixing of the catalytic material and char particles, which results in significant time and energy savings over methods of catalyst preparation that involve impregnation and calcining of a support material.

  • Patent number: 7851017
    Abstract: A method for forming a duct access region through one side of a previously installed air duct, wherein the air duct has an air flow with an air flow direction by inserting an aerosol injector into a previously installed air duct through the access region. The aerosol injector includes a liquid tube having a liquid tube orifice for ejecting a liquid to be atomized; and a propellant cap. The method is accomplished by aligning the aerosol injector with the direction of air flow in the duct; activating an air flow within the duct; and spraying a sealant through the aerosol injector to seal the duct in the direction of the air flow.

  • Patent number: 7207228
    Abstract: A method and apparatus for measuring fluid flow in a duct is disclosed. The invention uses a novel high velocity tracer injector system, an optional insertable folding mixing fan for homogenizing the tracer within the duct bulk fluid flow, and a perforated hose sampling system. A preferred embodiment uses CO2 as a tracer gas for measuring air flow in commercial and/or residential ducts. In extant commercial buildings, ducts not readily accessible by hanging ceilings may be drilled with readily plugged small diameter holes to allow for injection, optional mixing where desired using a novel insertable foldable mixing fan, and sampling hose.

  • Publication number: 20070001030
    Abstract: A clog-resistant injector spray nozzle allows relatively unobtrusive insertion through a small access aperture into existing ductwork in occupied buildings for atomized particulate sealing of a ductwork. The spray nozzle comprises an easily cleaned and easily replaced straight liquid tube whose liquid contents are principally propelled by a heated propellant gas, such as heated air. Heat transfer is minimized from the heated propellant gas to the liquid tube until they both exit the injector, thereby greatly reducing the likelihood of nozzle clogging. A method of duct sealing using particles driven by heated propellant gas is described, whereby duct-sealing operations become both faster, and commercially practicable in inhabited commercial and residential buildings.
