First Claim
Patent Images
1. A signal processing apparatus to determine a heart rate comprising:
- a plurality of sensors configured to detect changes in blood properties in a user'"'"'s skin; and
a heart rate Kalman filter configured to compute a heart rate on the basis of signals obtained from the plurality of sensors;
a communication link between the sensors and the heart rate Kalman filter to transmit the signals; and
a housing to contain at least the plurality of sensors to maintain them in proximity to the user'"'"'s skin.

Abstract
A signal processing apparatus for determining a heart rate includes a plurality of sensors configured to detect changes in blood properties in a user'"'"'s skin and a heart rate Kalman filter configured to compute a heart rate on the basis of signals obtained from the plurality of sensors. A method of computing a heart rate using the apparatus includes detecting changes in blood properties with a plurality of sensors, and computing with a heart rate Kalman filter the heart rate on the basis of signals obtained from the plurality of sensors.
