Abstract
A heart monitoring system includes at least two sensors embedded in a seat, such as a driver's seat in a vehicle. One of the sensors obtains a phonocardiogram (PCG) of the driver's heart in addition to noise. Another sensor is a reference sensor that obtains a noise signal, but does not include the PCG signal. Processing circuitry receives the heart signal with the noise and the reference noise signal, and performs adaptive filtering to remove the noise from the heart signal. Further analysis detects a heart rate or other heart measurements in the heart signal, and may output an alert if a heart condition is detected.
