Abstract: In a method of producing video screen holograms, a real video screen is illuminated by means of a narrowband light for producing a hologram of the real video screen. A plurality of individual recordings is carried out, each covering only a partial area of the real video screen being imaged in the hologram. The individual recordings take place, for example, by means of a scanning pulsed laser beam. The individual recordings are assembled to form the video screen hologram of the entire video screen. A recording device for this purpose comprises a scanning device for guiding the light radiation over the video screen and a light source which generates pulsed light radiation. The light source is, for example, a laser system with a pulsed q-switched oscillator and with an optical parametric oscillator.

Abstract: A shock-absorbing structure component has two cover layers and an intermediate layer that is arranged between them. The intermediate layer extends in an alternating form between the cover layers, with the material of the intermediate layer being selected such that it has a higher capacity elongation prior to breaking than that of the outer cover layer. The energy of an impact can thus be absorbed as the intermediate layer is stretched into a bag shape and the inner cover layer breaks off progressively.

Abstract: In a method of generating a pulse-shaped transmitted output signal having a definable pulse shape in a multistage amplifier arrangement, the course of the “pulse top” (upper edge) of the transmitted signal is determined by control signals at the amplifier stages. The control signals of the amplifier stages are definable such that the control signal of an amplifier stage in each case comprises a number of pulse sections of a predefinable frame pulse. The tops of the pulse sections each having a predefinable constant gradient. A predistortion is introduced into the control signals in this manner, having a course which offsets distortion of the pulse top which results when no predistortion is used.

Abstract: A method of controlling an analog actual signal to conform to a digital desired signal uses a comparator with two input ports and one output port and a digital-to-analog converter. The analog actual signal to be converted is fed to one input port of the comparator and a analog output signal of the digital-to-analog converter is fed to the other input port of the comparator. The digital input signal fed to the digital-to-analog converter is adapted as a function of the output signal of the comparator in a definable number of iterative steps, between a definable lower and a definable upper threshold, according to the balancing method. The digital input signal fed to the digital-to-analog converter corresponds to the digital desired signal to which the analog actual signal is converted.

Abstract: Image data of optically acquired input images (1) are processed for emphasizing at least two object classes. Each pixel is subjected to a rough classification (10) based on first criteria that determine whether or not a pixel is relevant for an object recognition. A reduced image (11) is formed from the relevant pixels and irrelevant pixels are omitted. The reduced image (11) is filtered (20) for forming at least two correlated filtered images (21, 22, 23) based on second criteria. Classified images (31A, 32A, 33A) are formed from the filtered images by classifiers that work in accordance with predetermined rules. Weighting factors are allocated to each object class. The classified images are merged in accordance with an algorithm to make a combined global evaluation for each object class. The global evaluation decides, based on the merged images (41A, 41B, 41C), for each pixel whether the respective pixel belongs to an object class and if so to which object class.

Abstract: A flight control display shows a representation of terrain, the horizon, an aircraft with a fuselage and aircraft wings, and a gamma ladder. The observer has a viewing direction at least in a predefined attitude range, which viewing direction is directed along the momentary flight path. The aircraft is therefore rotated depending on its momentary angle of incidence and angle of yaw with respect to the observer's viewing direction. The representation of the terrain is obtained from the relative position of a geodetic system of coordinates XG, YG, ZG and an aerodynamic system of axes of the airplane, in which case a reference line of the gamma ladder coincides with the horizon.

Abstract: Navigation signals emitted by a navigation transmitter (46), in a first signal path (41), have a time reference generated and, based on this time reference, navigation signals are generated which are subsequently emitted by way of a transmitting device (39, 40). In the event of interferences in the first signal path (41), a switch-over takes place to a second signal path (45) parallel to the first signal path (41). The navigation transmitter (46) receives time reference signals and/or navigation signals, and the received signals are guided by way of the second signal path (45) to the transmitting device (39, 40) and emitted.
