Abstract: A tunnel for mounting above a road surface (3) comprises a plurality of tunnel segments (1). Each tunnel segment is adapted for mounting at least one projector (6) therein, above a respective opening formed by the tunnel segment in a ceiling of the tunnel. The openings (5) of the plurality of tunnel segments are spaced apart in succession in a direction of travel of vehicles in the tunnel. The tunnel segments are disposed such that projection surfaces (8) of the projectors are seamlessly contiguous or overlapping on the road surface in the direction of travel. The tunnel may comprise awnings positioned at its entrance and its exit, the ceiling being formed at least in part by the awnings. A first awning (10A) may be mounted to a first tunnel segment, in the direction of travel, and a second awning (10B) may be mounted to a last tunnel segment, in the direction of travel.

Abstract: A system (1) for displaying an optical image (2) by means of unmanned autonomous vehicles. Each vehicle has a display for displaying at least a part of the image (2) by way of stored or transmitted image information as well as a control unit (9). The control unit (9) is configured to control the image information and to move the vehicle using a drive unit (11) by means of stored or transmitted positon information. At least two vehicles are configured as land crafts (5), wherein the displays (3) of the land crafts (5) are oriented in parallel to a substantially horizontal image plane (6) and configured as displays (3) accessible by a human person.

Abstract: A system composed of at least two unmanned aerial vehicles, each aerial vehicle comprising a drive unit, a flight control unit for controlling the trajectory of the aerial vehicle by means of the drive unit and a rechargeable power cell. Each aerial vehicle comprises an electrical first interface, and the system comprises at least one transport device with at least one chamber defined by boundary elements, in particular corner elements, for receiving the aerial vehicles stacked essentially vertically in the operating position and an electrical control and supply system for charging the power cells and/or for communicating with the flight control units via the first interfaces.

Abstract: An unmanned aerial vehicle having a drive unit for enabling the flight of the aerial vehicle in air space and having a flight control unit, which is configured to receive control information from a radio remote control or to control positions of the aerial vehicle in air space that employ stored position information in order to control the flight course of the aerial vehicle. A modular flight formation control unit has a first interface with the flight control unit and a second radio interface to a flight formation ground control unit or with flight formation control units of other aerial vehicles, and the flight formation control unit configured to generate or send control information corresponding to the radio remote control and is configured to output, via the first interface, flight formation control information relevant for the formation flight of at least two aerial vehicles to the flight control unit.

Abstract: A system for controlling at least two unmanned aerial vehicles in a flight formation, wherein each aerial vehicle has a flight control unit for controlling the flight path of the aerial vehicle and a camera that may be rotated by an orientation means about one axis, wherein in the system there is provided a flight formation control unit for the wireless communication with the aerial vehicles. The flight formation control unit is configured to control the flight control units and the orientation means during a recording of a moving object that will be filmed so that a spatial arrangement of the aerial vehicles in relation to the object and the orientation of the optical axis of each camera in relation to the object and/or in relation to the orientation(s) of the optical axis/axes of the other camera(s) is substantially maintained and optionally adjusted substantially in real time.
