  • PPG measurement of arterial health using disease library
    Patent number: 10881309
    Abstract: The arterial health of an individual can be determined by: attaching a fingertip photopiethysmography device to a fingertip of the hand of the elevated arm of the individual; measuring the analog pulse contour of the individual using the fingertip photopiethysmography device; digitizing the analog pulse contour; analyzing the digitized pulse contour for stable waveforms; processing the stable waveforms of the digitized pulse contour using dynamic time warping; comparing the stable waveforms to a library of known disease state waveforms; and assigning a most probable disease state for the individual based on said comparison.
    Type: Grant
    Filed: September 20, 2011
    Date of Patent: January 5, 2021
    Assignee: Arterial Stiffness Inc.
    Inventors: Michael Zhang, Zhaopeng Fan, Marshall Ring, Sara Korosch, David Keenan, Gerald Lefevre
