Title: The Innovations of Richard J Hellinga

Introduction

Richard J Hellinga is a notable inventor based in Sagamihara, Japan. He has made significant contributions to the field of displacement detection technology. His innovative approach has led to the development of a unique patent that enhances the accuracy of displacement measurements.

Latest Patents

Hellinga holds a patent for a "Displacement Detecting Apparatus." This invention features a magnetic scale constructed by arranging a non-magnetic material at a predetermined pitch in the direction of motion of a piston rod. It includes a pair of magnetic sensors that output two sine waves with a phase difference of 90 degrees, corresponding to the pitch of the magnetic scale. The peak voltages of the sensor output at each pitch are updated and stored. Center voltages are computed from these peak voltages, allowing for the calculation of coarse displacement. Correction coefficients are derived from the peak and center voltages, which are then used to compensate the sensor outputs. Finally, fine displacement is computed using an inverse trigonometric function from the corrected signals, resulting in a comprehensive displacement signal.
