Latest Patents

Daniel J Linehan holds a patent for a "Method and apparatus for generating motor current spectra to enhance." This invention involves a method and circuitry designed for sampling periodic amplitude modulations in a nonstationary periodic carrier wave. The goal is to determine frequencies in the amplitude modulations effectively. The method ensures that the sampled data set contains an exact whole number of carrier wave cycles by defining the sampling rate of motor current data collection. The circuitry is designed to recreate a sampled data set containing stationary carrier waves from the analog motor current signal, which includes nonstationary carrier waves. This is achieved by conditioning the actual sampling rate to adjust with frequency variations in the carrier wave. After transforming the sampled data to the frequency domain using the Discrete Fourier Transform, the frequency distribution in the discrete spectra of those components due to the carrier wave and its harmonics is minimized. This allows for easier analysis of signals of interest.
