Abstract: A method for the computer-aided learning of a control of a technical system is provided. An operation of the technical system is characterized by states which the technical system can assume during operation. Actions are executed during the operation and convert a relevant state into a subsequent state. The method is characterized in that, when learning the control, suitable consideration is given to the statistical uncertainty of the training data. This is achieved in that the statistical uncertainty of a quality function which models an optimal operation of the technical system is specified by an uncertainty propagation and is incorporated into an action selection rule when learning. By a correspondingly selectable certainty parameter, the learning method can be adapted to different application scenarios which vary in statistical requirements. The method can be used for learning the control of an operation of a turbine, in particular a gas turbine.

Abstract: A switching regulator is configured as a fixed-voltage regulator and contains a voltage divider. The voltage divider is supplied with a voltage signal available from a regulator output via a first connection. The voltage divider feds an output signal to the driver circuit functioning as a regulating variable that is compared to a reference voltage. The switching regulator further contains a monitoring device which impinges the driver circuit with a voltage signal exceeding the reference voltage as a new regulating variable depending on the voltage signal applied to the first connection.

Abstract: In order to operate a communication terminal for packet-oriented data transmission, at least one piece of status information is stored, for a communication terminal, in a memory unit associated with the communication terminal. Said status information is provided with a digital signature that is calculated from the status information by means of a private key for an asymmetrical encoding method associated with a first control unit associated with the communication terminal, for the resolution and/or conversion of network addresses. If the first control unit fails, a request is transmitted comprising the status information and the digital signature to associate the communication terminal with at least one second control unit, and the digital signature is checked. In the event of a positive check result, the communication terminal is associated with the second control unit.

Abstract: The invention relates to a method for controlling an actuator which can be displaced between two end positions, said actuator being impinged in one end position and being capable of displacement to the other end position by an electromagnetic part. The actuator is first supplied with an electromagnetic current using a pulse-duration modulation in a retaining mark space ratio. Once the application of current has ended, an oversaturation of the electromagnet is taken into consideration, either by influencing the application of current in the mark space ratio in an appropriate manner, or the oversaturation is completely prevented by a suitable configuration of the application of current.

Abstract: Managing incoming calls and/or messages in a communications system In a communications system, incoming calls and/or messages are managed by checking upon receipt of a call and/or message—if a pre-defined availability status allocated to a recipient of the call and/or message is activated. Upon activation of a pre-defined availability status a pre-defined filter rule is applied to the call and/or message in accordance with the activated availability status. A call and/or message handling action associated with the activated availability status is executed.

Abstract: The system has a demodulator for duplex data transmission with quadrature amplitude modulation via two conductors with two oppositely transporting channels. The channels include an “upper” channel with a higher frequency band fo±Bo/2 and a “lower” channel with a lower frequency band fu±Bu/2. The two frequency bands do not overlap each other. Each of the channels transmits two digital signals at a respective symbol frequency fT, and the received modulated carrier signal is so sampled at a sampling frequency fAo in the case of the upper channel and fAu in the case of the lower channel, respectively. The frequencies are chosen in such a way that fo/fu is a rational number K and fAo=2fo.
