A mobile safety device (1) is for rescuing at least one person at risk of falling. The safety device includes a support device (2) in the form of a jumping cushion, jumping sheet, platform, base plate or stretcher for receiving and transporting the person at risk of falling. A positioning device (3) locally positions the support device (2) at the location of the person at risk of falling. At least one unmanned, remote-controlled drone (4a, 4b, 4c, 4d) is provided as the positioning device (3).

The present disclosure relates to a flying body. The flying body includes a mounting space for mounting an object, a loading port for loading the object in the mounting space, and a take-out port for taking out the object loaded in the mounting space, wherein the loading port and the take-out port are provided at least partially at different positions. According to such a configuration, even a person without specialized knowledge can operate it easily and safely.

A control device (200) includes a ground vehicle controller (230) that causes a ground vehicle to travel at a target area, an acquirer (210) that acquires state information expressing a state of a surface of the target area while the ground vehicle travels the target area, and a determiner (240) that determines, based on the acquired state information, whether or not an aircraft is landable at the target area.

A power transmission system that is adapted to transmit forces from a motor to a component comprises an externally threaded shaft 551 that is rotatably attached to the motor, an internally threaded fastener that is movably attached to the externally threaded shaft, a first element, and a second element that is movably attached to the first element at a second joint and that is rigidly attached to the component at a third joint.
