Abstract: While lithium-air batteries have been known, in which oxygen in the air is used as a positive electrode active material and lithium is used as a negative electrode active material, it is desired to provide a battery system capable of efficient utilization of oxygen. A battery system is provided, including: a lithium-oxygen battery; an oxygen compressing unit configured to compress oxygen released from the lithium-oxygen battery; a storage unit configured to store oxygen compressed by the oxygen compressing unit; and an oxygen supplying unit configured to supply oxygen stored in the storage unit to the lithium-oxygen battery.

Abstract: When bandwidth is dynamically allocated for audio communication via satellite communication, newly occurring audio communication can negatively affect the communication quality of the existing audio communication. Provided is a data communication apparatus that communicates via a satellite and includes an allocation control section that allocates in advance, for audio communication via the satellite, a bandwidth that is larger than a bandwidth needed for current audio communication being performed via satellite by at least a predetermined bandwidth. A program causes a computer to function as this data communication apparatus. A satellite communication system includes this data communication apparatus and this satellite.
