Title: Toshiaki Shiomi: Innovator in Living Body Inspection Technologies
Introduction
Toshiaki Shiomi is a notable inventor based in Nagoya, Japan. He has made significant contributions to the field of medical technology, particularly in the area of living body inspection apparatuses. With a total of 4 patents to his name, his work focuses on improving the detection and analysis of various health conditions.
Latest Patents
One of Shiomi's latest patents is a living body inspection apparatus designed to inspect Restless Legs Syndrome (RLS). This innovative device utilizes a pulse wave signal to obtain pulse intervals, which are then subjected to frequency analysis using a method known as CDM. The analysis extracts low frequency components ranging from 0.04 to 0.15 Hz and high frequency components from 0.15 to 0.4 Hz. An index is generated by applying an age-based amendment to the ratio of low frequency to high frequency components (LF/HF). This index helps determine whether the LF/HF ratio meets a predetermined threshold, indicating the presence of RLS. For instance, a ratio equal to or greater than 0.65 suggests a suspicion of RLS. The device accurately calculates signals that indicate autonomic nerve activity, ultimately determining the state of RLS.
Another significant patent involves an apparatus for detecting vital functions, which includes a pulse wave sensor that can be attached to the body and a control unit. The control unit monitors the amplitude of pulse wave signals produced by the sensor. It checks for significant changes in amplitude during both the systolic and diastolic phases of the heart. If a large change occurs during the diastolic phase, it may indicate a motion artifact, prompting the system to set a motion artifact flag. Additionally, if a cough is detected, a cough flag is set, and if neither condition is present, a yawn flag is activated.
