Title: Innovations by Yoshiharu Harada

Introduction

Yoshiharu Harada is a notable inventor based in Tokorozawa, Japan. He has made significant contributions to the field of medical technology, particularly in the development of monitoring devices and physiological signal processing systems. With a total of 5 patents to his name, Harada continues to push the boundaries of innovation in healthcare.

Latest Patents

One of Harada's latest patents is a monitoring device that includes a receiving unit, a processing unit, and an information providing unit. The receiving unit is designed to receive a first photoplethysmogram signal acquired by irradiating a subject's body with a first light of a specific wavelength, along with a heartbeat signal corresponding to the subject's heartbeat. The processing unit calculates a fundamental frequency of heart rate based on the heartbeat signal and estimates a fundamental frequency of pulse rate by comparing it with the photoplethysmogram signal. The information providing unit then delivers information based on the estimated pulse rate.

Another significant patent is for a pulse oximeter, which consists of a light-emitting device that emits two different lights, and a light-detecting device that outputs signals corresponding to the intensity of these lights after they interact with the subject's tissue. The processing device calculates the pulsation rate and percutaneous arterial oxygen saturation of the subject, estimating the capillary refill time based on changes in these values during tissue compression. An output device then provides information indicating the capillary refill time.
