Latest Patents

One of his latest patents is titled "Method for Calibration of Dynamic Motion Sensors." This invention presents an improved method for calibrating dynamic motion sensors. The method involves sending a low-frequency driving signal to an exciter to generate harmonic movement in a shaker table. An optical position sensor is used to produce an output representative of position, allowing for the computation of acceleration of both the shaker table and the sensor under test. This process enables a comparison of the sensor's output with the instantaneous acceleration of the shaker table across different frequencies, defining the performance characteristics of the sensor within a selected frequency range. Another aspect of this patent includes the simultaneous direct measurement of position and time for calibration purposes.

Additionally, Sill holds a patent for a "Reference Sensor Method for Calibration of Dynamic Motion Sensors." This invention outlines a method for determining the magnitude and phase calibration of dynamic motion sensors, such as accelerometers and velocimeters, at low vibration frequencies. The method utilizes an optical encoder as a reference to calibrate the sensitivity of the dynamic motion sensor mounted on a shaker mechanism. This approach addresses the inadequacies of conventional reference accelerometers at low frequencies, providing a more accurate optical measurement.
