Abstract: The invention relates to a system and a method for combining and representing signals of a hardware simulation device and elements of a program listing, and an error locating tool. In order to be able to jointly represent the signals of the hardware simulation device and the elements of the program listing, the hardware simulation device simulates the behavior of a circuit comprising a processor, a program memory that contains the program code, and application-specific hardware components and generates signals as a result of said simulation, the elements of the program listing are combined with the signals generated during the simulated execution of the program codes which are contained in the program memory and correspond to said elements, and the elements of the program listing can be represented in a first partial area of a graphic display means while the signals can be represented in a second partial area of the display means.

Abstract: A combined component consists of a heat exchanger and a reactor. The heat exchanger is designed in a plate form, and flow spaces for a first medium and a second medium are alternately defined between successive plates. The plates of the heat exchanger are configured as essentially annular. The heat exchanger has, substantially perpendicularly to the plates, a tubular outer wall and a tubular inner wall. The reactor is surrounded by the inner wall of the heat exchanger. The product of the reactor is conducted through supply orifices on the inner wall of the heat exchanger into the flow spaces for one of the two fluids in the heat exchanger.

Abstract: A laser echoe ranging device (lidar) is used both to measure cloud height and to measure slant range visibility. For the latter purpose at various elevation angles, the distance for which the echoe gets down to the noise level is measured by a counter and the echo voltage for a distance selected by a time switch is also stored, for example for various distances in 100 meter steps. These values can be used to compute the slant visual range and, with reference to the data for the different angles of elevation, also the layer structure of an inhomogeneous scattering characteristic of the atmosphere.
