Abstract:
Die Vorrichtung zum Erzeugen einer Zufallszahl umfaßt eine Einrichtung (2) zum Abtasten eines Rauschsignals, um einen Rauschsignal Abtastwert zu erhalten. Der Zufallszahlengeneratorumfaßt ferner eine Einrichtung (5) zum Bereitstellen von Rauschsignal-Schwellenwerten, wobei die zumindest drei Rauschsignal-Schwellenwerte so gewählt sind, daß eine erste Wahrscheinlichkeit, daß der Rauschsignal-Abtastwert zwischen dem ersten und dem zweiten Rauschsignal-Schwellenwert liegt, und eine zweite Wahrscheinlichkeit, daß der Rauschsignal-Abtastwert zwischen dem zweiten und dem dritten Rauschsignal-Schwellenwert liegt, sich weniger als einen vorbestimmten Differenzwert voneinanderunterscheiden oder gleich sind. Eine Einrichtung (3) zum Ausgeben der Zufallszahl arbeitet auf der Basis der Rauschsignal-Schwellenwerte, und zwar derart, daß, wenn der Rauschsignal-Abtastwert zwischen dem ersten und dem zweiten Rauschsignal-Schwellenwert ist, eine erste Stelle einer Zufallszahl mit einem ersten logischen Zustand belegt wird.

Abstract:
The invention relates to a method for designing a technical system. According to said method, a technical system is modelled by means of a pre-determined quantity of target functions depending on parameters, each individual target function being weighted with a weighting factor. The inventive method solves a system of equations comprising the parameters and the weighting factors as variables in a variable space, solutions of the system of equations forming working points of a solution space in the variable space. Said working points are determined by means of a predictor-corrector method, according to which a predictor produced by means of a stochastic variable is determined in the variable space, from a first working point, and a second working point is then determined in a correcting step. Said determined working points are used to design the technical system. The inventive method can be used to redesign, modify or adapt an already existing technical system.
Abstract:
According to the invention, a plurality of cumulative current flows fulfilling a pre-determined selection criterion can be determined from detected cumulative current flows. At least one cumulative current flow fulfilling a pre-determined second selection criterion can be selected from the determined cumulative current flows, as a cumulative current flow representing a sensor signal. The sensor element to which a sensor signal is applied is determined from the selected cumulative current flow.
Abstract:
Disclosed is a device for generating a random number, comprising a unit (2) sampling a noise signal so as to obtain a noise signal sampling value. The random number generator also comprises a unit (5) supplying noise signal threshold values, the at least three noise signal threshold values being selected in such a way that a first probability that the noise signal sampling value lies between the first and the second noise signal threshold value is different by less than a predefined difference value from or identical to a second probability that the noise signal sampling value lies between the second and the third noise signal threshold value. A unit (3) issuing the random number operates based on the noise signal threshold values in such a way that a logical state is allocated to a first position of a random number if the noise signal sampling value lies between the first and the second noise signal threshold value while another logical state which is different from the first logical state is allocated to a second position of the random number such that one noise signal sampling value results in an at least 2-bit wide random number. Random numbers comprising any number of bits can be generated if more than three noise signal threshold values are used. The inventive device allows random numbers to be generated in a fast and efficient manner.
Abstract:
A processor arrangement comprises a number of processor units. Each processor unit is coupled to at least one adjacent processor unit by means of a bi-directional communication interface. Messages are exchanged between adjacent processor units for the determination of the separation of a processor unit in the processor arrangement from a reference position. Each message contains separation information, giving the separation of the processor unit receiving the message from the reference position or the separation of the processor unit sending the message from the reference position, where each processor unit is embodied such as to be able to determine or store the separation thereof from the reference position from the separation information in a received message.
