Abstract: An air conditioning device (10) is an air conditioning device (10) for a reclining seat (10) comprising a seat part (1b) and a backrest part (1a), the air conditioning device (10) comprising a ventilator and a controller (11). The ventilator is provided to at least one of the seat part (1b) and the backrest part (1a), and includes a first air flow path (A1, A2) formed inside the seat part (1b) or the backrest part (1a). The controller (11) determines a reclining state of the backrest part (1a) with respect to the seat part (1b), and controls air in the first air flow path (A1, A2) in accordance with the determined reclining state.

Abstract: A sound reproduction device is configured to store a head of a user and reproduce sound. The sound reproduction device includes: a headrest portion; a partition portion attached to the headrest portion so as to protrude forward relative to a front surface of the headrest portion; a speaker disposed in the partition portion; and a sound absorbing structure provided in at least a part of the inner surface of the partition portion excluding a region corresponding to an output surface of the speaker.

Abstract: An acoustic apparatus includes the peripheral wall which is provided so as to surround the seat and in which the upper portion is opened, and the speakers which are provided inside the peripheral wall so as to face the seat and can output the reproduced sound from the sound source. The speakers are disposed in front of the ears of a person sitting on the seat.

Abstract: An acoustic control system includes a peripheral wall provided so as to surround a seat, and an upper portion of the peripheral wall being opened, a speaker provided inside the peripheral wall and capable of outputting a reproduced sound from a sound source, a microphone provided toward an outside of the peripheral wall and configured to collect an environmental sound around the peripheral wall, and a processor. The processor configured to suppresse a level of the reproduced sound in a predetermined frequency band from the speaker based on the environmental sound collected by the microphone.

Abstract: The communication device is installed in an aircraft and is capable of radio communication with a base station on the ground. The communication device comprises a transmitter, a receiver, and a controller. The controller acquires location information of the aircraft at a predetermined time, and communicates with the base station using an allocation pattern of communication resources according to the location information of the aircraft.

Abstract: An image transmission apparatus is connected to a plurality of cameras that image the interior of a moving body, and includes a receiver, a processor, and a transmitter. The receiver receives, from an external device of the moving body, an image transmission request and imaging subject information that identifies a passenger to be imaged. The processor selects, based on the imaging subject information, an image captured by at least one camera of the plurality of cameras, and executes processing to remove, from the selected image, other image regions aside from the image region that covers the passenger to be imaged. The transmitter transmits the image that has been processed to the external device.
