There is provided a sound and vibration information collecting mechanism, which collects low-frequency sound and vibration information with a predetermined frequency or lower from a detection target, the mechanism including a resonance layer, which includes a natural oscillator having a natural frequency within a frequency band of the sound and vibration information being a collection target, and generates a resonance carrier by the natural oscillator emphasizing the sound and vibration information; and a sensor, which detects the resonance carrier. The mechanism detects a bioacoustic signal and a biosignal more accurately than conventionally.

Acoustic and vibration information accumulation mechanism, acoustic and vibration sensing system, and computer program

A device determining a biological state of a driver more accurately, including a hypnagogic symptom phenomenon detecting mechanism, an imminent sleep phenomenon detecting mechanism, a subjective sleepiness/low consciousness traveling state detecting mechanism, and a homeostasis function level determining mechanism, which are configured to function in parallel. Therefore, detection of a hypnagogic symptom phenomenon or an imminent sleep phenomenon, or detection of a period resisting a light sleepiness mild sleepiness or a strong sleepiness which occurs consciously, or the case where a low consciousness traveling state due to a decrease in consciousness level momentarily occurs or the case where it occurs longer continuously, or the like, can be determined/detected, and the driver's biological state can be accurately determined.
