Title: Kisei Hirobe: Innovator in Geomagnetism Technology
Introduction
Kisei Hirobe is a notable inventor based in Miyagi-ken, Japan. He has made significant contributions to the field of geomagnetism, holding a total of 5 patents. His work focuses on developing advanced sensing devices and programs that enhance the accuracy of geomagnetic measurements.
Latest Patents
Hirobe's latest patents include a geomagnetism sensing device and an azimuth calculation program. The geomagnetism sensing device features an X-axis sensor, a Y-axis sensor, and a Z-axis sensor that detect a geomagnetic vector. The device seeks the direction of the geomagnetic vector in spherical coordinates based on the detection output of each sensor. A reference axis is established in the spherical coordinate system, and a hypothetical central point is determined based on data from two coordinate detection points. The device calculates a rotational axis for movement centered around this axis.
The azimuth calculation program is a computer-executable program that performs azimuth calculations using the output from a magnetic sensor. This program includes steps to generate a triangle in three-dimensional space using three output values from a magnetic sensor unit, determine the circumcircle of the triangle, and perform an azimuth calculation using the center coordinates of the circumcircle along with the sensor output values.
