摘要： A determination section of a sleep control apparatus determines an awakening point based on target data. The target data is time-series data of biological information of a target person in a target period. The target period is a period between wakefulness to failing asleep of the target person, or a period from the wakefulness of the target person to a time point at which a predetermined time has passed since the target person fell asleep. The controller controls a target device so that the target device stimulates the target person to wake up at the awakening point.

摘要： A vortex ring generation device includes a casing having a gas passage and a discharge port, and an extrusion mechanism that extrudes a gas in the gas passage such that the gas in a vortex ring shape is discharged from the discharge port. V (m3) represents an extrusion volume, D (m) represents a diameter of the discharge port, L (m) represents a length of a cylinder having the diameter D and the volume V, and Re represents a Reynolds number of the discharged gas. 500≤Re≤3000 and 0.5≤L/D≤2.0.
