The electro-conductive fabric (e-textile or e-fabric) as an electrode for ECG measurement is one of the best application for ubiquitous healthcare system. However, it is difficult to measure the bio-signal due to its sensitivity variation caused by impedance change, especially by motion of the subject. In this paper, adaptive motion artifacts reduction(More)
We proposed non-contacting respiration signal monitoring system for sleep apnea syndrome. Experiments were conducted by emitting 40 kHz ultrasound beam, which is set tone burst mode by 1 ms period to a subject chest. Normal respiration condition and a simulated sleep apnea syndrome condition were measured while subjects were holding breath. To obtain the(More)
The e-health infrastructure in Korea has come a long way within a short period since the establishment of the Korea e-Health Association in 2003 by the Korean Ministry of Commerce, Industry and Energy. Since then, four related government departments in the Ministry of Health and Welfare, Ministry of Information and Communication, Ministry of National(More)
BACKGROUND Numerous studies have been conducted regarding a heartbeat classification algorithm over the past several decades. However, many algorithms have also been studied to acquire robust performance, as biosignals have a large amount of variation among individuals. Various methods have been proposed to reduce the differences coming from personal(More)
This study investigates a medical headlamp which is designed to adjust LED light automatically on the X axis and Y axis plane as determined a surgeon during a surgery. The needs of surgeons are determined through a CMOS camera which detects the movement of the eye. The system is composed of a mechanical actuator and an electrical control center. The LED(More)
BACKGROUND Blood pressure is a critical bio-signal and its importance has been increased with the aged society and the growth of cardiovascular disease population. However, most of hypertensive patients have been suffered the inconvenience in monitoring blood pressure in daily life because the measurement of the blood pressure depends on the cuff-based(More)
