摘要： The present invention relates to a method of associating at least one state in a plurality of states to a new value output by a drifting sensor, the method comprising: /a/ receiving a signal from the sensor, said signal comprising a plurality of values; /b/clustering the values of said signal into a number of clusters equal to the number of the plurality of states, each cluster being associated with a respective state in the plurality of states; /c/ for the new value of the signal, associating at least one state in said plurality of states or a probability rating representing the probability to be associated with one state in said plurality of states for said new value of the signal, the associated state or the associated probability rating being determined based on at least distances (dH, dL) of said new value of the signal to respective clusters.

摘要： A non-invasive method to determine a current functional blood oxygen saturation level: acquiring, at a sampling frequency, a photoplethysmography light response for each wavelength of a plurality of at least three wavelengths, resulting respectively in a first, second and third raw data series, 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 determining respectively in a first, second and third AC data series representing an unmodulated amplitude response, 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, apparatus and computer program wherein the method comprises: identifying a plurality of extrema points in a detected biosignal; comparing the identified extrema points with a plurality of sets of reference points wherein different sets of reference points correspond to different frequencies of the biosignal; and identifying the set of reference points that most closely fit the identified extrema points to determine a frequency of the biosignal.
