Title: Hiroshi Abe: Innovator in Orientation Detection Technology

Introduction

Hiroshi Abe is a notable inventor based in Sendai, Japan. He has made significant contributions to the field of orientation detection technology, holding a total of 4 patents. His work focuses on utilizing advanced gyroscopic and piezoelectric technologies to enhance the accuracy of orientation measurements.

Latest Patents

One of Hiroshi Abe's latest patents is an orientation angle detector. This device employs gyroscopes to detect X-, Y-, and Z-angular velocities, which are time-integrated to produce pitch, roll, and yaw angles (γ, β, α) of the orientation. The system incorporates two accelerometers to obtain tentative pitch and roll angles, which are then corrected, along with a yaw angle derived from two terrestrial magnetometers. When the tentative angles are accurately defined, the integrated angles are adjusted accordingly.

Another significant patent is a piezoelectric vibratory gyroscope that utilizes an energy-trapping vibration mode. This gyroscope consists of a piezoelectric plate with a principal surface polarized in the thickness direction. It features multiple electrodes positioned at the vertices of a polygon. When excited in the energy-trapping vibration mode, the rotation of the plate generates a Coriolis force, leading to secondary vibrations that induce electric voltages at the electrodes. The voltage differences detected at these electrodes are crucial for accurate orientation detection.
