A read-back channel for a pulse-width modulated digital signal, which is tapped behind an element for galvanic separation, is provided for monitoring generation of the analog output signal, and a unit is provided for monitoring the analog output signal to maintain a specifiable maximum deviation from a reference signal, which is generated in the same manner as the analog output signal by low-pass filtering from the pulse-width modulated digital signal. In the case of transient signals, the monitoring unit advantageously detects error states quickly and appropriate measures for reacting to the error states can therefore be implemented in less time.

At least one of the fact elements is assigned property information which represents a processing instruction for the assigned fact element for the translation of the rules and/or data. A translation of the rules and/or data is affected.

Abstract: A magnetic resonance sequence model that is a formal description of a measurement sequence is used to automate measurement sequence programming. The sequence model allows a system-independent specification of the measurement sequence for execution in a magnetic resonance scanner. The sequence model is as formal as possible; it is limited to the minimum required information for description of a measurement sequence without limiting the flexibility in the sequence programming. A method for formal description of the measurement sequence describes the measurement sequence by a number of parameters to be parameterized. The parameterization of the measurement sequence can ensue automatically from the formalized description of the measurement sequence, except for a set of parameters that are still be determined.

Abstract: A method for securely encrypting or decrypting a message or for generating or verifying a digital signature in a message, in which the message is subjected, with the aid of a processor, to a mathematical operation using a key (k) which can be represented in the form of a binary number with a sequence of bits, and computational operations are sequentially carried out on auxiliary variables for each bit. The dependence of the computational result on the values of individual bits is taken into account by reading the memory addresses from the auxiliary variables and assigning them to address variables. The difference between the addresses is calculated and, depending on the respective current bit, is added to, or subtracted from, the computer addresses. The assignment of the auxiliary variables to the address variables can thus be interchanged. As a result, the order and selection of the computational operations is controlled on the basis of bits without the program sequence having to contain jump instructions.
