Abstract: The present disclosure relates to a method of navigating an unmanned aerial vehicle (UAV). The method includes the steps of controlling a flight path of the UAV by a remote operator, obtaining a recognized air picture of an observation space surrounding the UAV, assigning one of a plurality of threat levels to each of the aerial vehicles, the threat levels comprising a resolution advisory level and an automatic avoidance level and continuously automatically determining viable avoidance trajectories for the UAV). If an aerial vehicles is assigned the resolution advisory level, a message is provided to a remote operator including a first proposed viable avoidance trajectory. If an aerial vehicles is assigned the automatic avoidance level, control signals are provided to an on-board flight controller instructing the vehicle to follow a flight path corresponding to a second proposed viable avoidance trajectory.

Abstract: The present disclosure relates to a method of obtaining a recognized air picture of an observation space surrounding an automated aerial vehicle. The method comprises the steps of receiving first signals of first cooperative systems of aerial vehicles within the observation space using a first receiver on board the automated aerial vehicle and receiving second signals of second cooperative systems of aerial vehicles within the observation space using a second receiver on board the automated aerial vehicle. The first receiver and the second receiver are adapted to receive signals according to different protocols. The first signals and the second signals are processed using a processor on board the automated aerial vehicle to obtain tracking information with respect to the aerial vehicles within the observation space.

Abstract: A holding apparatus for the vertebra of a spinal column. It furthermore has a mount for a bar which is provided at the side of the holding apparatus which faces away from a clamping screw. The clamping screw of the holding apparatus produces a rigid connection of the holding apparatus to the bar which is located in the mount. The apparatus retains the bar in the mount and can be brought into connection with the holding apparatus so as to temporarily retain in the mount a bar which is introduced into the mount until the holding apparatus is fixed to the bar by way of a rigid connection.
