Abstract: A method for tracking a moving target object, in particular a vehicle. The method involves identification the target object, marking the target object with a marking invisible in the visible spectrum but retro-reflective in a selected wavelength range of the invisible spectrum of light, tracking the marked moving target object with an image capture device provided on a moving platform, which image capture device is sensitive in the selected wavelength range of the invisible spectrum.

The computing unit is designed to control the first representation unit in such a way that a scenario stored in the memory unit together with the action subjects represented by the representatives are reproduced.

Abstract: A method for recognition of a predetermined pattern in an image data set recorded by a device for recording of at least two electromagnetic frequency spectra is provided. A first difference value is formed for the image points of the selected area as a function of a difference between a data vector of a corresponding image point and a first reference data vector. A second difference value is formed for an image point of a selected area as a function of a difference between the data vector of this image point and a second reference data vector. A predetermined pattern is recognized when it is determined at least one pattern correlation quantity is below a predetermined threshold value and a local minimum is present.

Abstract: A system for open space data communication comprising a transmitting device and an optical receiver using multiple varying levels of emitted radiation output. The transmitting device includes multiple emitter groups that are capable of being switched on and off and each of which can be activated in parallel to emit fixed, varying radiation outputs. A total radiation output emitted by the transmitting device is defined by a sum of the emitted radiation outputs of the emitter groups, wherein to transmit a bit vector (b0 . . . bn) an emitter group assigned to a most significant bit (b0) emits a maximum radiation output Pmax and emitter groups assigned to the less significant bits (b1 . . . bn) of the bit vector emit radiation outputs: Px=Pmax/2x where x=1 . . . n.

Abstract: A system and method for determining the pH value of a liquid. The system and method excite the liquid molecules in the liquid by light with a predetermined wavelength and an intensity component, transmitted through the liquid in a predetermined wavelength range, of the light used for excitation is captured. This intensity component is used to produce a wavelength/intensity absorption characteristic and this absorption characteristic is related to a reference absorption characteristic associated with a specific pH value of the liquid. The system and method thus can be used to obtain drinking water from a fuel for aircraft.

Thrust vector control includes a thrust current region for a thrust current of a propulsion stream having a flow direction; a steering mechanism for the thrust current including at least one steering device arranged at least in a peripheral region of the thrust current region, and the at least one steering device includes a rotational body with a lateral surface and a rotational axis arranged transverse to the flow direction, and the rotational body being rotatable so that a first part of the lateral surface exposed to the thrust current rotates in a first rotational direction, whereby a Magnus effect is produced to deflect the thrust current. The first rotational direction is in a direction of the thrust current.

Abstract: The rotors of a helicopter are directly connected with electric high-torque motors, and are powered by the latter. Energy generation and rotor drive are separate from each other. The high-torque motor of the main rotor is pivoted to the cabin canopy, so that it can be tilted together with the main rotor.

Abstract: Techniques for the detection of moving objects in a video image sequence are provided. Distinctive image variation points in a difference image are determined. An image variation threshold value is established and image variation points are determined as those points in the difference image in which the absolute image brightness value of which exceeds the image variation threshold value. The quality of the image variation points are determined based on at least one predetermined quality criterion. If the quality criterion is met, the determined image variation points determined are determined as the distinctive image variation points determined. Otherwise, the establishment of an image variation threshold value and determination of the quality of image variation points is repeated with a changed image variation threshold value.

Abstract: The rotors of a helicopter are powered by electric motors. The electrical energy required for this purpose is produced by a motor-generator unit, which comprises one or more internal combustion engines. The motor-generator unit can be secured under the cabin floor. This yields a hybrid helicopter that can set the rotational frequency of the rotors within a large interval.
