摘要： A method to determine breath disturbances of a user, in a device comprising three LEDs (11,12,13) configured to emit light rays at three wavelengths, a photodiode (2,3), a control unit (6) and a motion sensor (14,15), the method comprising :
a- acquiring, at a predefined sampling frequency, a PPG light response for each wavelength, resulting in a first, second and third raw data series representing an amplitude response, and acquiring motion signals, resulting in a fourth raw data series,
b- applying feature extracting filters to the raw data series, for outputting pattern channels comprising:
- variation (DSpO2) of blood oxygen saturation level,
- variation (DRSA) of Respiratory Sinus Arrythmia,
- variation (DRR) of Respiration Rate,
- Motion index,
- Heart Rate Variation,
- variation of AC and/or DC component of PPG light response,

c- applying a 1D CNN to the pattern channels for determining a breathing disturbance event and AHI.

摘要： A non-invasive method to determine a current functional blood oxygen saturation level (SpO2) :
a- acquiring, at a sampling frequency, a photoplethysmography light response for each wavelength of a plurality of at least three wavelengths (λ1, λ2, λ3), resulting respectively in a first, second and third raw data series,
b- applying a low-pass filter to each of the first, second and third raw data series, resulting respectively in a first, second and third DC data series representing an unmodulated amplitude response
c- determining respectively in a first, second and third AC data series representing an unmodulated amplitude response,
d- applying a computation engine to the first, second and third AC and DC data series, and determining therefrom a user current blood oxygen saturation level.

摘要： A method implemented in a system (10) which comprises a lightweight personal wearable monitoring device (1), supplied by a battery, comprising an accelerometer, a processing unit (2), a display (4), a remote server (3), said method comprising the steps :
/a/ collecting, from a plurality of individuals caused to practice various physical activities from a set of predefined activities, acceleration data from sensing devices placed on each of said individuals,
/b/ defining N small data-size specific metrics, computed from acceleration signals, which allow to define a global activity classifier,
/c/ acquiring, at a first monitoring device worn by a first user, acceleration signals from the accelerometer of the first monitoring device,
/d/ calculating, at the first monitoring device, over each lapsed time unit T1, specific metrics values from the sensed signals, to form a series of specific metrics values,
/e/ send them to the processing unit,
/f/ allocate an activity type for each time unit together with corresponding specific metrics values of the received series, to form a time chart of activity types presumably performed by the first user over a second period T2,
/g/ display the time chart of activity types presumably performed by the first user on the display and allow the first user to confirm or correct partly the type of activity performed over the second period, and allow correction by the first user.
