Electrical and audio anatomy-signal sensor system
First Claim
1. A sensor system for the combined, simultaneous, common-axis collection of heart-produced acoustical and electrical signals comprising a body of revolution possessing an axis of revolution which is substantially coincident with said common axis, and having a hollow interior, and a pair of opposite faces spaced along, and substantially centered on, said axis of revolution and opening to said interior, an electrical electrode structure mounted on the outside of said body and disposed angularly symmetrically with respect to said axis of revolution, a sound transducer disposed within said interior, substantially centered on said axis of revolution, and oriented to collect acoustical signals entering said body through one of said faces, and a cushion of revolution circumsurrounding and supporting said transducer in a manner which substantially fills the majority of said hollow interior.

Abstract
A sensor system for the combined, simultaneous, common-axis collection of heart-produced acoustical and electrical signals. The system includes (a) a hollow-interior body of revolution possessing an axis of revolution which is substantially coincident with the common signal-collection axis, (b) an electrode structure mounted on the outside of the body and disposed symmetrically with respect to the signal-collection axis, (c) a sound transducer disposed within the interior of the body, substantially centered on the signal-collection axis, (d) a cushion of revolution circumsurrounding and supporting the transducer within the body in a manner which substantially isolates the sound transducer from spurious noise events, and (e) an anatomy-adhereable acoustic membrane, disposed in the path for sound collection to act as a mechanical anatomy-to sensor impedance-matching coupler assisting in sound-signal collection.

13. A sensor system for collecting anatomy-produced signals comprising
a sensor body including an internal acoustic chamber with a mouth exposed to one side of said body adapted to face a subject'"'"'s anatomy for the purpose of receiving anatomy-produced acoustical signals, a sound transducer mounted within said body and operatively and communicatively exposed to said chamber, an acoustic membrane spanning said mouth, and having one side facing said chamber and an opposite side facing away from the chamber, and an anatomy adhesive layer distributed over said membrane'"'"'s said opposite side accommodating releasable bonding of the membrane'"'"'s said opposite side to a selected site on a subject'"'"'s anatomy.
