#$%^&*AU2015215845A120160310.pdf#####1001181599 ABSTRACT A device for determining a heart rate of a user has a PPG sensor and an accelerometer to compensate for acceleration artifacts within the PPG signal. The device transforms time domain PPG and accelerometer signals into the frequency domain using a Fourier transformation and utilizes the Fourier coefficient magnitudes as indicative of the probability of candidate heart rate values. Candidate heart rate values are determined at sampling times over a time interval and a most probable heart rate path during the time interval is determined using a reward/penalty algorithm.1/16 D CUD U) o ) CL CU 0 0 ) U)U co CD 4-000r CD _ _ _ _ _ _ _ _ _ _ _ __u_ _
