Title: Rie Ohsaki: Innovator in Physiological Condition Detection

Introduction

Rie Ohsaki is a notable inventor based in Anjo, Japan. She has made significant contributions to the field of physiological condition detection, holding a total of 6 patents. Her innovative work focuses on methods and apparatuses that enhance the understanding of sleep conditions and pleural pressure.

Latest Patents

One of her latest patents is a method for detecting the physiological condition of a sleeping patient based on the analysis of pulse waves. This method detects pulse waves from the body of a patient and creates an envelope by connecting every peak of the pulse waves. It determines that the patient is in non-REM sleep if the envelope fluctuates regularly, while irregular fluctuations indicate REM sleep. The method further calculates and normalizes the amplitude and period of the envelope to assess conditions such as obstructive sleep apnea syndrome and central sleep apnea syndrome.

Another significant patent is an apparatus and method for electronically predicting pleural pressure from pulse wave signals. This invention predicts pleural pressure based on pulse wave signals that are continuously produced and picked up in a time-sequential manner. It acquires variation signals from the pulse wave signals to predict pleural pressure based on the differences between these signals.
