Latest Patents

Patrik Paajarvi holds a patent for a method titled "Method for rolling bearing fault detection based on enhancing statistical asymmetry." This method involves digital processing of vibration signals from rolling bearings in rotating machines. It allows for high-reliability fault detection by applying a linear, adaptive filter to the acquired vibration signal. The filter is iteratively tuned to increase the statistical asymmetry of its output, effectively removing phase- and amplitude distortion from underlying fault impulses. Additionally, the method achieves suppression of sinusoidal disturbances while maintaining high robustness to measurement noise. The result is a processed signal that facilitates easier detection of rolling bearing defects.
