Abstract: A method for providing an air display comprising a multiplicity of unmanned aircraft comprising: automatic loading of mission data of a plurality of unmanned aircraft into the data store of an unmanned aircraft via the ground station by means of the first data connection, querying and storing identifiers, GPS data, and the system status from a plurality of the multiplicity of unmanned aircraft by the control unit by means of the first or second data connection, calculating the flight paths for the plurality of unmanned aircraft based on the GPS data and the first target positions of the respective unmanned aircraft by means of the control unit in real time, assigning flight path numbers to a plurality of the unmanned aircraft by the control unit by means of the first or second data connection, and independent and synchronized performance of the entire mission by the unmanned aircraft after the launch.

Abstract: A ground station device for a plurality of unmanned aircraft, comprising an upper face, which comprises a plurality of receptacles for positioning a plurality of unmanned aircraft, a data interface for connecting the ground station device to a control unit, and a power supply device for charging the unmanned aircraft. The ground station device is designed to be stackable so as to form a stack with at least one other ground station device.

Abstract: Multi-stage reduction of impact forces are disclosed. An example apparatus to reduce impact energy of an aircraft during landing includes a rotatable landing leg having a proximal end near an axis of rotation and a distal end opposite the proximal end, a first flexible portion of the proximal end, where the first flexible portion is to engage a first engaging portion at a first rotation angle of the rotatable landing leg, and a second flexible portion of the distal end, where the second flexible portion is to engage a second engaging portion at a second rotation angle of the rotatable landing leg.

Abstract: The invention relates to a method and a system for providing an aerial display, comprising: a plurality of unmanned aerial vehicles, each having a light means, a data store and an identifier; at least one base station which communicates with the aerial vehicles via a first data connection; and at least one control unit which can communicate indirectly with the aerial vehicles via the base station and directly via a second data connection.

Abstract: Flexible printed circuit boards and related methods are disclosed herein. An example printed circuit board includes a controller interface coupled to a surface of the printed circuit board between a first end of the printed circuit board and a second end of the printed circuit board. The example printed circuit board includes a connector coupled to the surface proximate to the first end. The example printed circuit board includes a notch formed between the controller interface and the connector. The notch is to form a narrowed portion of the printed circuit board to enable the printed circuit board to bend at the narrowed portion.
