Claim 3:
4. The apparatus of claim 3, wherein the at least one criterion associated with the sensed signal or the reference signal includes at least one of a sensed signal threshold or a reference signal threshold, and the processor is configured to modify the state noise covariance of the fixed lag Kalman smoother by:
incrementing the state noise covariance of the fixed lag Kalman smoother in a stepwise manner over a plurality of time points when at least one of (i) the sensed signal is greater than a sensed signal threshold or (ii) the reference signal is greater than a reference signal threshold; and
decrementing the state noise covariance of the fixed lag Kalman smoother in a stepwise manner over a plurality of time points when at least one of (i) the sensed signal is less than a sensed signal threshold or (ii) the reference signal is less than a reference signal threshold.
