Stethoscope system including a sensor array
First Claim
1. A stethoscope system, comprising:
- a patch that includes an array of pressure sensors and a user feedback system, the patch including flexible material that allows the patch to be conformed to a patient'"'"'s body; and
a control system capable of;
receiving signals from the array of pressure sensors, the signals corresponding to measurements from multiple pressure sensors of the array of pressure sensors;
combining signals from multiple pressure sensors of the array of pressure sensors to produce combined signals;
filtering the combined signals to remove, at least in part, breathing signal components and to produce filtered signals; and
determining a correspondence between heart signal components of the filtered signals and corresponding heart valve activity, wherein the control system includes one or more components from a list of components consisting of;
a general purpose single- or multi-chip processor;
a digital signal processor;
an application specific integrated circuit;
a field programmable gate array or other programmable logic device, discrete gate or transistor logic, and a discrete hardware component and wherein the control system is capable of providing instructions, via the user feedback system, regarding placement of the patch on a patient'"'"'s chest.

Abstract
A stethoscope system may include an array of sensors, which may include pressure sensors. The array may be implemented in a wearable “patch” that is conformable to a patient'"'"'s body. The stethoscope system may include a control system that is capable of receiving signals from the array of sensors. The signals may, for example, correspond to measurements from multiple pressure sensors of the array. The control system may be capable of combining signals from multiple pressure sensors to produce combined signals. The control system may be capable of filtering the combined signals to remove, at least in part, breathing signal components and to produce filtered signals. The control system may be capable of determining a correspondence between heart signal components of the filtered signals and corresponding heart valve activity.
