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 is configured to release an airflow in a form of a vortex ring from a release port. The vortex ring generation device includes a plurality of gas chamber units, an actuator, and a communication path. Each gas chamber unit has an air chamber that communicates with the release port. Each gas chamber units includes a fixing member forming the air chamber, and a movable member moving to push air out of the air chamber. The movable members of all of the gas chamber units are coupled together to form one movable body. The actuator is connected to an end portion of the movable body and is configured to drive the movable body. The communication path allows the air chambers of the plurality of gas chamber units to communicate with each other.

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: The present invention provides an image capturing apparatus capable of easily finding an unsatisfactory point peculiar to a group picture at the time of taking a group picture and capable of taking a group picture with which all of subjects to be photographed are satisfied.

Abstract: A digital camera has an operation portion including at least one main operation member and provided on the back surface of a camera body, and a slide portion including a main display device and provided on the back surface of the camera body. The slide portion is sidable between a housed position that covers the operation portion and an image capturing position that exposes the operation portion on the camera body.

Abstract: A camera has a lens barrier which can move between a closed position where a taking lens is covered and an opened position where the taking lens is exposed, and the on/off state of a power source is switched interlockingly with the open/close state of the lens barrier. A housing for housing the camera has a barrier driving lever for driving the lens barrier. At the time of attaching the housing, the tip of the barrier driving lever is retained by a finger retaining part of the camera to move the lens barrier to the opened position. As a result, attachment of the housing in a power-off state made by the lens barrier can be prevented.
