  • Publication number: 20220178816
    Abstract: The present disclosure relates to the technical field of fiber-optic gas sensing and laser photoacoustic spectroscopy, and reliability of a gas detection system is improved by actively selecting a working frequency of low noise interference combined with an optical fiber photoacoustic sensing probe capable of isolating high-frequency noise. A gas enters a photoacoustic microcavity through gaps on a sound-sensitive diaphragm after diffusing into a miniature air chamber through a plurality of micropores. Photoacoustic excitation light is incident into the photoacoustic microcavity through a fiber-optic collimator and then excited to generate a photoacoustic pressure wave to cause the sound-sensitive diaphragm to vibrate periodically. An end face of a single-mode optical fiber and the sound-sensitive diaphragm constitutes a fiber-optic Fabry-Perot interferometer. The interferometer measures a deflection of the diaphragm and inverts a concentration of the to-be-measured gas.

  • Patent number: 11356792
    Abstract: A computer converts each content sources from textual content to speech comprising a separate audio selection. The computer applies, to each audio selection, one or more speech attributes to specify the audio attributes that select a respective position of the respective audio selection from among multiple positions within a multidimensional sound space and audibly distinguish one or more characteristics of the respective audio selection from other audio selections, wherein the respective position of the respective audio selection reflects a rank of the respective audio selection as ordered by interest to a user. The computer outputs a simultaneous stream of the multiple audio selections to an audio output device for stereo play of the audio selections within the multiple positions within the multidimensional sound space to the user, with the multiple positions reflecting the content sources ordered by interest.
