Latest Patents

One of his latest patents is the "Dynamic Digital Tracking Filter." This system measures the magnitude component corresponding to the once-per-revolution frequency or a multiple thereof of the vibration signal generated by a body rotating at a non-uniform rate. The output of a sensor detecting the acceleration of the vibration motion of the rotating body is decomposed into its frequency components. Simultaneously, the information from a tachometer sensor, which detects the rotational speed of the rotating body, is utilized to determine the variation of the rotational speed during the measurement interval. The speed variation information is selectively combined with the frequency components of the acceleration spectrum to yield the magnitude result that would be measured if the rotating body had a constant rotational speed. This method provides vibration information in select frequency bands that is corrected for the non-uniform rate of rotation of the body.

Another notable patent is the "System and Method for Ratiometrically Processing Sensed Speed." This digital ratiometric tracking filter offers superior measurement of the magnitude and phase of vibration of a rotating body, whether at uniform or non-uniform rotational speed. The sensed speed and vibration signals are processed concurrently and subsequently combined to produce absolute magnitude and relative phase measurements. The concurrent processing of the sensed signals ensures that any system-introduced errors are identified in both signals and can be uniformly eliminated through ratiometric processing.
