Abstract:
An apparatus includes a sensor module configured for receiving sensed information indicative of a sensed signal. The sensed signal includes a source signal component and a source noise component. The apparatus also includes a reference module configured for reference information indicative of a reference signal. The reference signal also includes a reference noise component. The apparatus also includes a filter module configured as a fixed lag Kalman smoother. The filter module is configured for adaptively filtering the reference signal to generate an estimate of the source noise component. The apparatus also includes a processing module configured for calculating an output signal based on the sensed signal and the estimate of the source noise component. The apparatus also includes an interface module configured for transmitting an indication of the output signal. The filter module is further configured for, based on the output signal, tuning the Kalman smoother.

Claim (Index 4):
The apparatus of  claim 1 , the filter module configured to tune the Kalman smoother by modifying the state noise covariance, the filter module configured to modify the state noise covariance by:\n when at least one of (a) the sensed signal exceeds a sensed signal threshold, or (b) the reference signal exceeds a reference signal threshold, incrementing the state noise covariance up to a state noise covariance threshold based on a state noise covariance increment; and when (c) the sensed signal is below the sensed signal threshold, and (d) the reference signal is below the reference signal threshold, decrementing the state noise covariance based on the state noise covariance increment.
