摘要： A method for protecting an integrated circuit against unauthorized access to key registers, wherein functions and/or applications of the integrated circuit are unlocked and/or activated via data stored in key registers, such as during the start-up of the integrated circuit and/or during ongoing operation, where if such a key register is accessed, the data word used to perform the access is compared with specified key data, and if access via a data word deviating from the specified key data is detected, the access is marked as unauthorized, the access marked as unauthorized is then recorded and evaluated, and after the analysis, appropriate protective measures are triggered to prevent further unauthorized access such that a key register method for protecting sensitive data is expanded in a simple manner and hacker attacks are quickly detected and thwarted.

摘要： An improved control unit for an inverter, which control unit includes an R-C arrangement used as a synchronizable sawtooth voltage generator, a comparator having the sawtooth voltage as its inverting input and a control voltage as its non-inverting input with positive and negative feedback provided from the output to the input of the comparator thereby causing the comparator to act as an oscillator once the sawtooth voltage exceeds the control voltage thereby allowing long and short pulses developed to be changed into pulse trains or pulse series. The design is such that the feedback can be connected and disconnected and furthermore that a differentiating capacitor can be connected in or bypassed, thereby giving the control unit the capability of providing long pulses, short pulses, long trains of pulses or short trains of pulses. As a result, a mass produced control unit can be used with various types of equipment by connecting and disconnecting the proper soldered jumpers.

摘要： A method for determining absolute speed of a rail vehicle including onboard sensor devices and a signal processor, wherein the method includes the steps of detecting irregularities in the rail respectively on one front wheel set via a first sensor device and at least on a subsequent wheel set via another sensor device, and transmitting the sensor signals produced by the sensor devices to a signal processor configured to determine the absolute speed by analyzing the supplied sensor signals, where an estimation of the transfer function between a sensor is used, and where an FIR filter can, in this case, optimally reproduce the signal of one sensor via the signal of the other sensor in which the smallest square of the error is formed such that the time offset between both signals can be determined, from which the speed can be determined at a known distance of the sensor.
