This paper presents a monitoring system with an ultrasensitive vibration sensor to detect heartbeat. The likelihood of fatal accident while bathing in Japan is higher than any other European country. The domestic accidents at bathroom have increased 1.7-fold over the past 10 years. Monitoring systems in a bathroom are therefore needed to prevent accidents that can't be foreseen. In this study, we...
Recently, as the number of elderly people increases, much more caregivers are required for the support for them. However the number of caregivers and therapists is not enough in the current situation. In this paper, we propose a support system for the elderly introducing robot partners, sensor networks, and portable sensing devices in informationally structured space. In the system, human state estimation...
This paper proposes a human localization method in sensor networks for monitoring elderly people. First, we explain the proposed intelligent sensor networks. Next, we apply a spiking neural network to extract feature points for human localization from a measurement data by sensor networks. Furthermore, we propose a learning method using spiking neural network based on the time series of measurement...
Recently, the social role of the nursing health facilities increases more and more as Japan becomes an aged society. The health care should be done according to meals, daily exercise, sleep, and others. In this paper, we focus on the monitoring of sleep using optical oscillosensor and pneumatic s for the health care to elderly people. In these sensors, two thresholds are used for the state estimation...
