  • Patent number: 10004410
    Abstract: The present invention relates generally to a system and methods for measuring physiological parameters. More specifically, the present invention relates to a noncontact technology by which one or more physiological parameters of a subject may be efficiently and quickly detected. Among other advantages, the present invention can be used to assess and monitor vital signs of one or more subjects in a variety of contexts including for medical or security triage purposes, for use in healthcare waiting rooms, as part of human imaging systems, or during surgery.
    Type: Grant
    Filed: December 19, 2014
    Date of Patent: June 26, 2018
    Assignees: The Board of Trustees of the University of Illinois, The University of North Carolina at Chapel Hill
    Inventors: Stephen W. Porges, Maria I. Davila, Gregory F. Lewis

  • Publication number: 20130303941
    Abstract: Provided are methods and devices for evaluating dynamic middle ear muscle activity in a subject. A probe is provided having a speaker and a microphone in sound-wave communication with an eardrum associated with the middle ear muscle of the subject. A sound wave is generated from the speaker and transmitted to the eardrum. The sound wave that is reflected is detected and a reflected sound wave property measured. The input sound wave may be comb input to fully extend ossicle movement in all available vibratory modes, thereby providing maximum information as to dynamic middle ear muscle activity.

  • Patent number: 4510944
    Abstract: A method and apparatus is disclosed for detecting amplitude variations in the rhythmic oscillations of a physiological response pattern in a frequency range of interest. A sensor is used to detect an occurrence of an event in the cycle of a physiological response and the intervals between each reoccurring event is timed and placed in a buffer. The output from the buffer is readout at predetermined time intervals and fed to a filter which determines the aperiodic portion of the signal and subtracts that aperiodic portion to output a residual data signal. The residual data signal is fed to a band pass filter which filters in a region determined by the predetermined frequency range of interest and which outputs to a calculation and display device wherein the variance of the rhythmic oscillation is calculated and displayed.
