The high intelligent vital information acquisition sensor networks are needed, though the toilet help and independence support in the medical treatment and nursing field for elderly persons are the most important elements.
Accordingly, the technique to acquire highly developed vital information with the IoT sensor network will be lectured in this session. Concretely, the system that acquires elderly person's vital information on the getting up, the arrival floor, the heartbeat and breath from remoteness with the microwave Doppler rada and RFID system will be shown. By computing the received signal strength indication of the multiple RF-tags, it can recognize the location and posture of the patients. Combining the posture, location and vital information, it can finally recognize the behavior by using machine learning technology. In addition, results of the field test with a care facility for elderly people will also be introduced.

The role VNA (vector network analyzer) calibration is to define the measurement reference planes for subsequent S-parameter measurements. Specifically, VNA calibration defines where the reference planes are and what the values of reference impedances associated with those planes are. When, if ever, do the reference impedances assume a value other than 50Ω and how?
In this seminar, we will have a close look at the mechanics by which reference impedances assume a certain, possibly complex value.
