Title: Innovations by Kouji Andoh
Introduction
Kouji Andoh is a notable inventor based in Kariya, Japan. He has made significant contributions to the field of particulate matter detection systems. With a total of 7 patents to his name, Andoh's work has advanced the technology used in environmental monitoring.
Latest Patents
One of his latest inventions is a particulate matter detection system. This system includes a PM sensor, current detector, and control circuit. The control circuit switches between detection and burning modes. In detection mode, it prohibits power supply to a heater while allowing voltage between electrodes. This instructs the current detector to measure the current flowing between the electrodes. In burning mode, the heater generates heat energy to burn particulate matter accumulated on an accumulation part. The control circuit determines if particulate matter remains based on the detected current exceeding a threshold value, prompting a return to burning mode. Additionally, the system features a pair of current detectors that identify leak currents from the heater to the electrodes, enabling sensor failure detection. Another significant invention is a particulate matter sensor and sensing system designed for cost-effective production and accurate heater temperature measurement. This sensor includes a deposition portion for particulate matter accumulation, a pair of electrodes, a heater, and heater leads for electrical current delivery. A sensing line measures the resistance of at least one heater lead.
