Title: Masatsugu Kamimura: Vehicle Navigation and Position-Detection Innovations.

Introduction

Masatsugu Kamimura is an inventor associated with Kobe, Japan. His work includes vehicle navigation technologies that use map data, position measurements, and gyroscopic sensing to improve the accuracy of vehicle location and direction. He is credited with 4 patents.

Latest Patents

Kamimura’s listed patents include “Vehicle Position Detecting Apparatus,” which describes a navigation system that periodically compares a vehicle’s measured position and direction with nearby road data. The system corrects the measured position when map-matching results meet a specified similarity threshold, then displays the corrected position over the map.

Another listed invention, “Navigation System and Gyroscopic Device,” concerns calculating a vehicle’s track from bearing-sensor readings and matching its position to road data. It also describes conditions for withholding bearing correction when a large difference between the vehicle’s measured direction and the road’s direction could increase positioning error. The approach is intended to support accurate offset correction when a gyroscopic device is used as the bearing sensor.

Career Highlights

Kamimura’s career is associated with Fujitsu Ten Limited and Fujitsu Corporation. The patent descriptions reflect a focus on navigation systems, vehicle-position detection, map matching, and gyroscopic devices.

Collaborations

His listed collaborators include Atsushi Ichimura and Jyunichi Yamamoto.

Conclusion

Masatsugu Kamimura’s patent work addresses practical challenges in vehicle navigation by combining position measurements, road-map data, and sensor-based direction information to improve location accuracy.
