  • Dynamic control of voice codec data rate
    Patent number: 9208798
    Abstract: A method, system, and computer-usable non-transitory storage device for dynamic voice codec adaptation are disclosed. The voice codec adapts in real time to devote more bits to audio quality when it is most needed, and fewer bits to less important parts of utterances are disclosed. Dialog knowledge is utilized for compression opportunities to adjust the bitrate moment-by-moment, based on the inferred value of each frame. Frame importance and appropriate transmission fidelity is predicted based on prosodic features and models of dialog dynamics. This technique provides the same communications quality with less spectrum needs, fewer antennas, and less battery drain.
    Type: Grant

    Date of Patent: December 8, 2015
    Assignee: Board of Regents, The University of Texas System

  • Production of food
    Patent number: 5739030
    Abstract: The RNA content of Fungi Imperfecti, for example Fusarium graminearum can be reduced with low protein loss by heating it in the presence of its growth medium to a temperature above 68.degree. C. and separating growth medium from it.
