In recent years, one of the common issues is an e-Health care system which makes available health management and medical services at any time and in any place. This study describes the development of an e-Health care system that can promptly detect and cope with emergent situations happening to chronic disease patients in their everyday life.

The present study discusses the construction of a ubiquitous health care system that can cope actively with urgent situations of chronic disease patients who can lead everyday life despite their chronic diseases. If a patient's emergency is detected by personal health care host (PHCH), which is composed of USN, electronic stethoscope, GPS, CDMA and RFID, a(More)
We demonstrate a room-temperature operation of the near-infrared femtosecond optical parametric oscillator based on MgO-doped stoichiometric periodically-poled lithium niobate, which is synchronously pumped by a Kerr-lens mode-locked Ti:sapphire laser. Wide tunability in the range from 0.98 microm to 1.50 microm was enabled for a single set of cavity(More)
