Shuji Nambu is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of train safety and control systems. With a total of two patents to his name, Nambu's work focuses on enhancing the safety and efficiency of train operations.

Latest Patents

Nambu's latest patents include an onboard system and emergency brake control method. This system calculates a speed curve based on the measured traveling speed upon detecting a current balise. It sets a minimum required time period for traveling to the next balise and the subsequent balise. If the onboard system detects that the elapsed time period is shorter than the minimum required time, it activates an emergency brake to stop the train. Another patent involves a terminal protection apparatus and method. This invention ensures that a train activates an emergency brake when a Station Loop Coil (SLC) becomes undetectable before the train is confirmed to have stopped at a designated position. This mechanism prevents potential collisions with stop barriers at the end of the track.
