20140163407 | METHOD OF PROCESSING CARDIOVASCULAR SOUND SIGNALS - Each spectral slice array of a plurality is generated for each time segment of a plurality of time segments of a cardiovascular sound signal is convolved with a local spectral averaging window to generate a local spectral average array that is searched for bruit candidates responsive to associated time power or energy values, power levels, and skew values, so as to provide an indication of cardiovascular disease, that may also be responsive to skew-responsive and power-level-responsive probability terms and to a composite thereof. A probability indicator of cardiovascular disease is responsive to a second product of second terms, each second term responsive to a first product of first terms, each first term representative of a probability of no bruits for all time segments for each frequency segment of a two dimensional bruit candidate probability array, each second term representative of a probability of no repetitive bruits within each frequency segment. | 06-12-2014 |
