Title: The Innovative Contributions of Adrianus Josephus Smulders
Introduction
Adrianus Josephus Smulders is a notable inventor based in San Diego, CA. He has made significant contributions to the field of machinery condition monitoring, holding 2 patents that showcase his expertise and innovative thinking.
Latest Patents
One of his latest patents is the "Harmonic Activity Locator," which involves systems and methods for identifying the presence of defects in vibrating machinery. This exemplary method includes the analysis of frequency spectrum vibration data of the machine. It derives a harmonic activity index based on estimates of the energy associated with the frequency spectrum and the energy associated with the defect's harmonic series. The method also involves deriving a value K by estimating a value M indicative of the energy of the defect's harmonic series and dividing M by the number of spectral lines corresponding to the defect's harmonic series. Additionally, it derives a value R by estimating a value Q indicative of the energy in the frequency spectrum data and dividing Q by the number of spectral lines of the frequency spectrum data. The harmonic activity index is then derived based on the estimated K and R. Related systems for executing these methods are also disclosed.
Another significant patent is the "Envelope Enhancement System for Detecting Paper Machine Press Section." This invention is a vibration detecting and condition monitoring system for the press section, including felts, rollers, and presses. It employs a feature extracting circuit with a selectable plurality of Bessel type bandpass filters and an enveloping circuit to square the bandpassed signal output prior to FFT analysis of the signal. This system enables the enhancement and detection of highly impulsive signals in the frequency domain, which are indicative of defects in machinery operation.
