Title: Yuji Chotoku: Innovator in Motion Detection and Thermal Management
Introduction
Yuji Chotoku is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the fields of motion detection and thermal management for electronic components. With a total of 5 patents to his name, Chotoku's work reflects his commitment to advancing technology.
Latest Patents
One of his latest patents is a motion detection apparatus and motion detecting method. This innovative apparatus includes an acceleration sensor that detects motion-generated acceleration in electronic devices. It features a motion detecting section that calculates the average value of data from the acceleration sensor, determines the difference between this average and the last data value, and computes a pseudo-variance value. A threshold comparing section then assesses this pseudo-variance against a motion threshold to generate a signal when the threshold is exceeded. Additionally, the apparatus includes a buffer memory for storing signal values and a signal generating section that aggregates these values to accurately associate with motion.
Another significant patent is a method and system for thermal control of electronic components. This system utilizes both hardware and software data to periodically calculate a power consumption index. An internal database converts this power consumption data into the rotational speed of a cooling fan associated with the CPU. The system dynamically adjusts the fan's speed based on changes in power consumption, ensuring optimal thermal management.
