Classification: CPC A | IPC A

Claim 11:
12. A method of segmenting an auscultatory sound signal as recited in claim 1, wherein the operation of generating said local mathematical model comprises:
a. selecting a pair of points of said auscultatory envelope signal spanning in time a peak of said auscultatory envelope signal selected from the group consisting of a first peak of said auscultatory envelope signal corresponding to a first heart sound, and said second peak of said auscultatory envelope signal, wherein each point of said pair of points of said auscultatory envelope signal is selected so that a corresponding associated magnitude of said auscultatory envelope signal is not in excess of a fraction of a magnitude of said peak of said auscultatory envelope signal; and
b. mathematically fitting a quadratic function of time to a set of points comprising said pair of points of said auscultatory envelope signal and to said peak of said auscultatory envelope signal.
