Abstract With a sound sensing system using stochastic resonance (4SR), it became possible to obtain an acoustic pulse wave (APW)—a waveform created via a mixture of apex beat and heart sound. We examined 50 subjects who were healthy, with no underl

It is fair to conclude that people with a disorder in the brain and/or cardiovascular system are more likely to experience physical condition changes while driving, which may cause health-induced traffic accidents as a result. In response, we develop

We developed a seat suspension for use on earth-moving machines. The suspension’s mechanism consists of a torsion bar that produces non-linear spring characteristics, a magneto-spring, and a free play damper, which acts as a damping element despite

This paper proposes a novel technique to estimate continuous pulse pressure waves based on aortic pulse waves (APWs) that are measured in an unconstrained manner at the back of a user via an APW sensor. Frequency filtering and rectification are appli

In this paper, we propose a novel method for predicting acute clinical deterioration triggered by hypotension, ventricular fibrillation, and an undiagnosed multiple disease condition using biological signals, such as heart rate, RR interval, and bloo
