Patent ID: 8870783

Claim:
A method for determining a physiological parameter from a physiological signal using a processor of an electronic device, comprising: identifying at least one fiducial point on consecutive waves of the physiological signal, using the processor; wherein the at least one fiducial point comprises a peak of the physiological signal, a trough of the physiological signal, a dicrotic notch of the physiological signal, a point of maximum slope of the physiological signal, a point of maximum curvature of the physiological signal, a pulse mean crossing of the physiological signal, a point of zero crossing in the physiological signal, or a point of zero crossing in a derivative of the physiological signal, or any combination thereof; wherein corresponding fiducial points of the consecutive waves form sets of fiducial points; determining a fiducial period for each set of fiducial points using the processor; converting each of the fiducial periods to a respective Gaussian kernel function using the processor; summing the Gaussian kernel functions to create a distribution curve using the processor; determining the physiological parameter from the distribution curve using the processor; and displaying on a display the determined physiological parameter.
