JOURNAL FREE ACCESSThe concept of an experimental house called Welfare Techno House Mizusawa is to develop the life supporting system for the elderly without attaching any sensors for the human body. Since 1998, we have been tested suitable sensors which reflect the health condition and normal daily life. The human activity measurement based on installed pyroeletric sensors at individual room and electrocardiogram obtained form the electro conductive sheet were used. For the preventive medical point of view, the long-term monitoring were performed both the experiment house and elderly own residents.View full abstractDownload PDF (1319K) -

JOURNAL FREE ACCESSA statistical analysis is performed on the human activities in daily life . The data were obtained from seven infra-red ray sensors(attached by Ohta et al.)to several rooms at the single-living elderly home. It is shown that the position and movement of the person are finely reproduced, if a suitable pre-operation is performed on those data. A system for finding the abnormalities in activities is proposed based on the staying time distribution to characteristic states(places). Basic problems including the stationarity and the time-dependence of the statistics are investigated toward the realization of this system.View full abstractDownload PDF (1002K) -

JOURNAL FREE ACCESSTime-course analysis of activities of daily living(ADL)was performed by non-intrusive monitoring system and questionnaire. We analyzed the frequencies of sensor responses arranged in various sites of house during basic daily activities such as sleeping, getting up, going to bed, toileting, taking bath, washing, cooking and taking meals. It is assumed that performances of each basic daily activity could be confirmed by the activities of sensors responses. Monitoring of basic ADL is practical method to check the health status of aged person living alone.View full abstractDownload PDF (1165K) -
-Remote Monitoring System using Power-line network and Web-Based Application-Masayuki NAMBU, Takatoshi SUENAGA, Noriko ICHINOSEKI, Kazuki NAKAJIMA, ...2001 Volume 13 Issue 4 Pages 112-119

JOURNAL FREE ACCESSIn the aged society like Japan, some of the elderly cannot receive the enough care, because the relative number of a caregiver is reduced. To resolve this problem, we proposed the life support system which is called “e-house”, using an information network technology. Since the information infrastructure was different according to the living environment of the elderly, we had to develop the method to cancell the digital divide. We constructed the home network system which adopted a power-line network. The result of the experiment of communication using power-line network shows the power-line network has enough band width to transfer the biomedical signals like an ECG. In addition, we developed the WWW based tele-monitoring system for the elderly. As the result of experiments, we confirmed that this Web-based monitoring system is effective for the tele-monitoring of the health condition of the elderly.View full abstractDownload PDF (1119K) -

JOURNAL FREE ACCESSWe have recently developed a health monitoring system for the elderly living alone. We measured in-house movements by placing infrared sensors in each room of their houses without restricting them so that monitoring can last longer. Continuous monitoring was performed for 91 months in total to 8 subjects. We estimate their health condition by checking the staying periods at specific rooms such as a lavatory in comparison with the previous data statistically. If there is a unusual state after analysis, we have to inform the family of the incident. Final decision should be made by their family. After inquiring with the subject or his/her neighbors by telephone, family members may call an ambulance, if necessary.View full abstractDownload PDF (978K)
