Abstract: A system, method and computer program product for detecting indicators for structural changes of NMR active test molecules in a test sample, or indicators for structural changes of the environment of said test molecules in relation to a reference molecule. Initial local similarity values are obtained, using a similarity function and representing a local similarity between a reference spectrum and a test spectrum within corresponding similarity regions (SRR, SRT). The initial local similarity values represent a similarity map (SM1) in which contours of a first shape type are indicators (I1) for structural changes of the test molecule, and in which contours of a second shape type are indicators (I2) for structural changes of the environment of said test molecule in relation to the reference molecule.

Abstract: Systems and methods for improved NMR signal detection are described. The system receives NMR signal data produced by a sample over time in response to an excitation pulse and selects a predefined system function for application to the NMR signal data for systematic variation of signal properties The system function has a different influence on NMR signal components than on noise components of the sampled signal and has a variation parameter to control the systematic variation. A plurality of variation parameter values is provided with differing values to influence broad NMR signals as well as weak NMR signals. The system generates for each variation parameter value a corresponding intermediate data set by applying the system function with the respective variation parameter value to the NMR signal data. Further, from each intermediate data set, a respective base value centered spectrum is generated in the frequency-domain.

Abstract: The invention relates to a safety barrier for limiting the current and voltage of an electrical consumer (15) connected downstream thereof. The safety barrier comprises an input terminal (8) and an output terminal (16) and an input and output terminal (10, 17) of a common line (12), and has at least one voltage and current-limiting device (7, 13, 14), which comprises a fuse (F1), a voltage-limiting device (D3) that is associated with the common line (12), a current-limiting device (R6) that is connected to the output of the common line and an additional protection circuit that is located in front of the voltage and current-limiting device (7, 13, 14).

Abstract: The invention relates to a sensor device, particularly a limit or threshold value sensor device with a sensor system for detecting an external measured quantity, a switching device being provided for switching a load circuit. The known design of the switching device by means of transistors or electromechanical relays has always necessitated compromises with regards to the electronic functionality, design of the circuit and arrangement on or with the sensor device. The solution provided by the invention is a switching device with an almost wattless drive and galvanic separation or isolation between the control circuit and output circuit, the sensor system being constructed independent of the load circuit.

Abstract: A protective circuit for limiting the voltage for a device to be protected, particularly a load with an upstream-connected voltage and current limiting device. The device to be protected is provided in an output circuit of the protective circuit and is separable by means of a switching element, a voltage detector being provided with an electronic switch on the one hand and a voltage sensor on the other.
