Abstract: An attitude control device according to an embodiment includes a detection unit that detects an inclination of an aircraft, and a notification unit that performs a notifying process for passengers depending on the detected inclination. An aircraft according to an embodiment includes a detection unit that detects an inclination of an airframe, and a notification unit that performs a notifying process for passengers depending on the detected inclination of the airframe.

Abstract: An information processing device has a management unit and a determination unit. The management unit manages self-propelled cell devices. The cell devices include a first cell device that is the cell device of a first user. When power is lent to apparatuses of a second user using the first cell device, the determination unit determines the compensation returned to the first user by the second user on the basis of the power amount that was lent and a period for which power was lent.

Abstract: An information processing device includes a display controller. The display controller performs control to display the location in which a self-propelled battery apparatus, positioned within a prescribed area, is present, as an object representing the battery apparatus on a map representing the prescribed area or a part thereof. The object indicates the power generation origin of electric power with which the battery apparatus corresponding to the object has been charged.

Abstract: A mobile battery is provided that is easy to transport. The mobile battery comprises a battery body, a movement unit, and a motor. The battery body is configured to be chargeable and dischargeable, or replaceable. The movement unit is connected to the motor and is configured to be able to move the battery body. The motor generates motive power with electrical power supplied from the battery body. The mobile battery is configured to be self-propelled with the motive power, or to move using the motive power as auxiliary motive power for transportation.

Abstract: A home receives power supply from a secondary battery (fixed battery). An electricity delivery vehicle includes a built-in secondary battery (mobile battery), and moves autonomously. The home measures a battery charge level of the fixed battery and transmits the battery charge level to a server. When the battery charge level of the fixed battery at the home is lower than a power supply threshold, the server instructs an electricity delivery vehicle in a standby state to start moving. Upon receiving the start instruction, the electricity delivery vehicle sets the home as a goal point, and automatically starts moving. Upon reaching the home, the electricity delivery vehicle connects the built-in mobile battery with the fixed battery at the home, and supplies power from the mobile battery to the fixed battery.

Abstract: A secondary battery management device is connected with electronic equipment using a secondary battery as a driving power supply via the Internet. The secondary battery management device acquires performance information of the secondary battery from the electronic equipment, and measures a degradation level of performance of the secondary battery during a predetermined unit period. The secondary battery management device estimates a degrading speed of the secondary battery on the basis of the degradation level. The secondary battery management device may notify a user of the electronic equipment of the replacement timing of the secondary battery, use fees of the secondary battery, and the like.
