Eldon A. Byrd has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • System for creating and amplifying three dimensional sound employing phase distribution and duty cycle modulation of a high frequency digital signal
    Patent number: 6501399
    Abstract: A method of presenting audio information where changes in amplitude and changes in frequency in two channels (stereo) have the additional parameter of phase information added to re-create the feeling of a live performance. Also, all three parameters are converted into duty cycle modulation of a high frequency digital pulse. Conventional loudspeakers and the brain decode the signal to provide audio signals that contain more information than simply frequency and amplitude changes as a function of time.
