Title: Hidetoshi Fujimoto: Innovator in Traffic Signal Technology
Introduction
Hidetoshi Fujimoto is a notable inventor based in Urawa, Japan. He has made significant contributions to the field of traffic signal technology, holding a total of 2 patents. His work focuses on enhancing the safety and efficiency of traffic signal systems.
Latest Patents
Fujimoto's latest patents include a monitoring apparatus and control apparatus for traffic signal lights. This innovative system is designed for fail-safe monitoring of traffic signals at intersections where multiple roads converge. The apparatus utilizes sensor devices to detect the illumination conditions of each signal light. When the number of illuminated or non-illuminated signal lights reaches a predetermined threshold, it generates a normal judgment output indicating a high energy condition. Conversely, if the number of illuminated or non-illuminated lights does not meet this threshold, an abnormal judgment output is produced, indicating a low energy condition. This design ensures that if a fault occurs in the monitoring apparatus, the output condition mimics a danger situation due to a signal light abnormality. As a result, this system provides extremely safe monitoring and control of traffic signals with excellent fail-safe characteristics.
