Real-time, sound-quality-competitive, single-site from plural-site, anatomical audio signal selection
First Claim
1. A method employed in the gathering, for observation purposes, of desired-category anatomical audio signal information effectively from a selected anatomical region, said method comprising placing first and second audio signal sensors/detectors on the anatomy at selected locations of adjacency relative to such region, gathering, and competitively processing, the respective audio signals detected by these two sensors for the purpose of selecting, during a given, defined time-frame, one of these two detected signals as the higher-quality signal as such is determined by the review of certain pre-chosen quality-selection parameters, and declaring such selected higher-quality audio signal to be the one containing the desired-category audio signal information from the selected anatomical region during the defined time-frame.

Abstract
A method and apparatus for gathering high-quality anatomical audio signals. Practice of the invention, which is illustrated herein in the context of heart-produced signals, is based upon gathering, and competitively processing audio signals collected simultaneously from two adjacent anatomical sites. Competitive processing examines these two signals in light of certain selected “quality” parameters, and thereby selects the better signal at a user-selected point in time.

8. Apparatus for gathering and competitively selecting from plural candidates, for observation purposes, desired-category, anatomical audio signal information effectively from a selected anatomical region, said apparatus comprising
first and second audio signal sensors placeable on the anatomy at selected locations of adjacency relative to such a region, signal processing structure operatively connected to said two sensors for gathering, and competitively processing, the respective audio signals detected by said sensors for the purpose of selecting, during a given, defined time-frame, one of such two detected signals as the higher-quality signal as such is determined by the review of certain pre-chosen quality-selection parameters, and output structure operatively connected to said gathering and competitive processing structure, responsive to the performance thereof to declare a selected high-quality audio signal based upon the performance of said gathering and competitive processing structure.
