Title: Hirohide Sato - Innovator in Automotive Voltage Regulation

Introduction

Hirohide Sato, based in Toyokawa, Japan, is a distinguished inventor with a remarkable portfolio of 20 patents. His innovative contributions have significantly advanced the field of automotive technology, particularly in the regulation and detection systems of alternators.

Latest Patents

Among Sato's latest patents is the development of a generation-stop detection system for alternators. This system provides a generation-stop condition signal when the output voltage of the alternator drops below a predefined reference voltage. It comprises a rotation speed detection unit that monitors the alternator's speed, along with a reference voltage changing unit that adjusts the reference voltage proportionally to this speed. Additionally, a warning signal unit is integrated to alert users when the generation-stop condition is met, maintaining the warning even if the rotation speed subsequently increases, only interrupting once the alternator's output voltage exceeds that of the battery.

Another notable patent focuses on a voltage regulating system for vehicles equipped with alternators. This system utilizes a comparator to maintain battery voltage within normal ranges, adjusting the reference voltage based on the average battery voltages during engine operation. When these voltages surpass or fall below set thresholds, the system recalibrates the reference voltage accordingly, showcasing Sato's commitment to vehicle performance and reliability.
