ABSTRACT:
A method for use with an accelerometer that monitors movement of a machine component and generates acceleration values that include at least some noise associated therewith, the method for tracking machine component velocity via the acceleration values, the method comprising the steps of obtaining acceleration values from the accelerometer during machine operation, analyzing the acceleration values to distinguish noise signals from non-noise signals wherein a noise signal is an acceleration value likely solely attributable to noise, using the non-noise signals to identify a component velocity value and performing a secondary function to identify component velocity when noise signals are identified. The invention also contemplates a processor to perform the inventive methods.
