  • Method and system for evaluating the quality of a physiological signal
    Patent number: 12343175
    Abstract: A method, intended for the evaluation of the quality of at least one periodic or quasi-periodic physiological signal, which includes the steps of: segmenting the physiological signal temporally into a plurality of signal segments; for each given signal segment, determining a distance representative of a shape difference between the given signal segment and at least one signal segment temporally offset relative to the given signal segment; and determining a quality index of the given signal segment according to the distance determined for the given signal segment.
    Type: Grant
    Filed: October 2, 2020
    Date of Patent: July 1, 2025
    Assignee: BIOSENCY
    Inventors: Gurvan Priem, Quentin Bodinier
  • Method and system for evaluating the quality of ratio of ratios values
    Patent number: 12329503
    Abstract: A method intended for the evaluation of the quality of ratio of ratios (RR) values computed for at least two photoplethysmographic (PPG) signals corresponding to distinct wavelengths, each PPG signal including successive heartbeat patterns. The method includes the steps of: segmenting the PPG signals into a plurality of signal segments each corresponding to one heartbeat pattern; for each given signal segment, computing a sequence of RR values; and evaluating, for each given signal segment, a quality index of the sequence of computed RR values on the basis of a computed heart rate and/or a measured peripheral temperature corresponding to the given signal segment.
