An electronic device for improving a performance of a signal chain is described. The signal chain includes multiple electronic components. The electronic device further includes a control circuit. The control circuit is configured to receive a set of figures of merit, wherein the set of figures of merit includes at least one component-specific figure of merit for several different settings of several of the electronic components, respectively. The control circuit is configured to determine and/or receive at least one n-th moment characteristic of a signal of the signal chain. The control circuit is configured to determine at least one performance parameter for a plurality of different combinations of settings of the electronic components, respectively, wherein the at least one performance parameter is indicative of a performance of the signal chain. The control circuit is configured to determine the at least one performance parameter based on the set of figures of merit and based on the at least one n-th moment characteristic. The control circuit is configured to select a combination of settings of the electronic components based on the performance parameters determined for different combinations of settings of the electronic components. Further, a configuration method of configuring a signal chain is described.

Embodiments of the present disclosure relate to methods of finding optimized analog measurement hardware settings of a measurement system for a target measurement. The method can include one or more of the following steps: applying initial settings to the measurement system; varying the settings over a power sweep while processing a test signal used for the target measurement or a representative signal; performing the target measurement during the power sweep, thereby determining a hardware contribution of the measurement system over the power sweep; and identifying the respective settings that lead to a minimum hardware contribution of the measurement system at various powers.

A measurement device with automatic optimization capabilities comprises at least one signal processing component with a physical detector and a virtual detector component comprising at least one virtual detector for a signal processing component without physical detector. The physical detector is configured to physically measure a measurement value assigned to the signal processing component. The virtual detector component is configured to use a model of a signal processing chain from the physical detector to the location of the virtual detector. The model comprises at least one model parameter for the signal processing chain. The measurement device is configured to adapt the virtual detector component with respect to a measurement type for the signal to be measured. The virtual detector component is configured to use the model and the at least one measurement value. The virtual detector component is configured to determine a virtually determined value based on the model and the at least one measurement value. The measurement device is configured to use the virtually determined value to determine a setting for the measurement device. In addition, a method of setting a measurement device is described.

A measuring device for measuring a signal with a first component signal and at least one second component signal comprises a high-frequency processing device, which is embodied to mix the signal in order to form an intermediate-frequency signal and to digitize the latter in order to form a digital composite signal. The measuring device further comprises a digital mixer, which is embodied to generate a first digital composite test signal and a second digital composite test signal subject to a displacement of the frequency of the digital composite signal. Moreover, the measuring device comprises a digital filter, which is embodied to filter the first digital composite test signal in order to form a first digital test signal and to filter the second digital composite test signal in order to form a second digital test signal.

Lateral magnetic guidance apparatus for laterally guiding a wheel set of a rail vehicle with respect to a support rail. The apparatus includes electromagnets carried with the wheel sets and positioned and controlled so as to effect return of the wheel set to a central position along the rail whenever the wheel set deviates from the central position. At least one electromagnet is provided which has a multi-piece pole shoe with a plurality of pole faces disposed longitudinally spaced from one another along the support rail.

An internal combustion engine, especially Otto engine, which utilizes fuel gas supplied in a low-temperature liquefied state for the combustion process. Heat exchange means are provided for effecting a heat exchange between the intake combustion air and the fuel gas such that the combustion air is cooled down prior to combustion by its use as a heat-emitting heat-exchanging medium for preheating the low-temperature liquefied fuel gas. In one preferred embodiment, the heat exchange means is a mixing carburetor arranged upstream of the engine combustion chamber and in another preferred embodiment of the invention, the heat exchanger means is a non-contact heat exchanger for effecting heat transfer without mixing of the combustion air and fuel gas.

Bending beam arrangement for use in supporting elevated trains and the like, and method of making same. The profile member beam is formed as a composite structure having steel profilemember and a concrete profile member connected thereto. The concrete profile member is disposed and configured so as to maximally absorb the compression forces experienced by the bending beam while minimizing the total cross sectional area of the concrete so that the overall weight of the bending beam is maintained at a minimal level. By absorbing the compressive forces on the composite beam and thereby preventing buckling of the steel beam, a thin walled steel beam construction can be utilized hence substantially only significant tensile forces need be accommodated thereby. Various preferred geometrical embodiments are included with means being provided in each embodiment to accommodate supporting and guiding of an elevational or suspended train vehicle for movement therealong. Several preferred embodiments include closed profile steel girders having the concrete profile girder disposed inside the hollow space formed thereby. Other preferred embodiments of open steel beam construction are also included. In one preferred embodiment two pipes of different sizes are arranged one inside the other to form the steel profile member with a hollow space formed between the two pipes being filled with concrete constituting the compressive reinforcing concrete girder. In this last-mentioned embodiment, a longitudinal slot through both pipes is provided at the contact surface thereof for accommodating suspension of a train vehicle. The hollow space inside of the inner tube or pipe accommodate guide wheels for the vehicle as well as driving mechanisms and other support equipment. The method of manufacturing preferred embodiments of the composite steel concrete beam include controlling the temperature of the concrete mixture during curing so as to prevent formation of stresses due to dimensional changes in the concrete during curing.
