Abstract: An air-blowing apparatus includes a main body and a fan. In the main body a blow-out region is formed. The fan is provided in the main body and sends air toward the blow-out region. The air-blowing apparatus blows out air from the blow-out region such that a ratio (Vmax/Vmin) of a maximum value Vmax of wind velocity to a minimum value Vmin of the wind velocity is 1 or more and 10 or less in a target virtual plane. The target virtual plane is a virtual plane that faces the blow-out region. As a result, comfort of a person exposed to the wind sent from the air-blowing apparatus is improved.

Abstract: A partition has an air blowing function of blowing air to a predetermined region. The partition includes a casing, a blower mechanism arranged in the casing, and a blow-out port formed in the casing. On a virtual plane facing the blow-out port and having a wind velocity of 0.2 m/s or more, an airflow with an average momentum per unit area from 0.05 kg/ms2 to 0.75 kg/ms2 is generated.

Abstract: 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.

Abstract: A blower device includes a panel, a frame member disposed to surround the panel, a plurality of fans configured to blow out air through a plurality of blow out ports of the frame member, a control unit configured to control the rotational speed of the fans, and a camera configured to detect presence of a person in front of the panel. The control unit is configured to adjust the flow rate and the flow speed of air blown out through the blow out ports to thereby change the direction of an air flow generated by mutual collision of the blown-out air so that the air is blown out toward the person detected by the camera.

Abstract: A vortex ring generation device includes a casing having a discharge port, an extrusion mechanism, and a component supply port. The extrusion mechanism extrudes air in an air passage inside the casing such that the air is discharged, in a vortex ring shape, from the discharge port. The component supply port surrounds the air passage. A total circumferential length of the component supply port is ½ or more of a total circumferential length of the discharge port. The extrusion mechanism includes a vibration plate and a drive unit that vibrates the vibration plate. The air passage includes a first passage, and a throttle passage continuous with a downstream end of the first passage. A component chamber is provided inside the casing. The component chamber contains a discharge component to be supplied to the component supply port. The component supply port is located downstream of the throttle passage.

Abstract: An air blower includes: a panel (3); a frame member (5) arranged to surround the panel (3) and having a blowout port (13a, 13b, 13c, 13d, 13e, 13f, 13g) of air formed therein; and a fan (11a, 11b, 11c, 11d, 11e, 11f, 30) that sends air to the blowout port (13a, 13b, 13c, 13d, 13e, 13f, 13g). The frame member (5) produces airflows that are blown out from at least three directions and collide with each other, thereby producing an air current going forward to the panel (3).
