    • A signal simulation device for testing and developing radio receivers adapted to orientate antenna beams to different radio transmitters and to simultaneously suppress interference signals, comprises an antenna array, a signal generator generating reproducible digital signals in the complex baseband, and a digital matrix processor combined and synchronized with the signal generator. The processor has input signals generated by the signal generator and has output signals that form received signals of the antenna array. The input signals of the matrix processor are phase shifted according to a direction of incidence and to relative positions of the elements within the antenna array of the radio receiver, and are combined and supplied to outputs of the matrix processor. Amplitude and phase shift are simulated by weighting of the input signals from the signal generator, the weighting coefficients being calculated on a control computer and input into the matrix processor via an interface.

    • Disclosed is a digital line scan camera, having at least at least one focal plane, on which at least one linear photosensitive sensor is arranged, an objective lens, and a location measurement system. The location measurement system is used to determine six external location parameters, where the location system measurement comprises a satellite-supported position determination device and an inertial navigation measurement unit. The line scan camera includes at least on two-dimensional photosensitive sensor, which is synchronously driven with the linear sensor. At least one displacement vector ({right arrow over (x)}) is calculated from the data of the minimum of one two-dimensional photosensitive sensor, and where the displacement vector ({right arrow over (x)}) is used to correct the date of the inertial measurement unit.

    • For regulating the pressure in a pressure chamber, in particular in a pneumatic brake apparatus for a web-type recording medium, an actual pressure is set in the pressure chamber dependent on an actual angle of rotation of a rotary valve. The actual angle of rotation of the rotary valve and the actual pressure in the pressure chamber are acquired. A target pressure and a target angle of rotation allocated to this target pressure are predetermined, and a pressure deviation between the actual pressure and the target pressure are determined, as is a deviation of the angle of rotation between the actual angle of rotation and the target angle of rotation. An adjusting unit sets the angle of rotation at the rotary valve, first dependent on the deviation of the angle of rotation and then dependent on the pressure deviation. Furthermore, a sensor for acquiring the angle of rotation is specified.
