摘要： Bandwidth-selectable acoustic emission apparatus and methods for transmitting time-averaged signal data are described. An example apparatus includes an integrated external preamplifier device having a bandwidth-selectable analog filter and a data extractor. The integrated external preamplifier device is to receive an analog acoustic emission signal generated via an acoustic emission sensor operatively coupled to the integrated external preamplifier device. The bandwidth-selectable analog filter is to filter the analog acoustic emission signal based on a software-programmed bandwidth to generate a filtered analog acoustic emission signal. The data extractor is to extract a time-averaged analog signal from the filtered analog acoustic emission signal, and to transmit the time-averaged analog signal from the integrated external preamplifier device to an external data acquisition system.

摘要： Within the scope of the invention, a device for monitoring the quality of a fuel stored in a fuel tank has been developed. The main field of application is diesel-operated vehicles. The fuel is therefore preferably diesel fuel. The device is defined by the fact that means for determining the boiling point of the fuel are provided. Furthermore, a method for monitoring the quality of a fuel stored in a fuel tank has also been developed within the scope of the invention. The main field of application is diesel-operated vehicles. The fuel is therefore preferably diesel fuel. The method is defined by the fact that the boiling point of the fuel or a deviation of this boiling point from a normal value is measured. During the analysis of real injection pumps which have failed it has been detected that an excessively low boiling point of the fuel can cause the fuel to outgas. As a result, bubbles in which the necessary lubrication is no longer provided locally form in the injection pump. Furthermore, the lubricating effect is dependent on the fuel having a certain minimum viscosity. A low boiling point is also correlated with a low viscosity. Therefore, overall, the boiling point (initial boiling point, IBP) is a particularly good indicator especially of those deviations from standard values for the fuel which entail particularly costly damage.

摘要： According to an embodiment, a structure evaluation system has a plurality of sensors, a signal processor, and an evaluator. The sensors detect an elastic wave generated from a structure. The signal processor acquires a reliability from a source of the elastic wave to the plurality of sensors by performing signal processing on the elastic wave detected by the plurality of sensors. The evaluator evaluates the soundness of the structure on the basis of the acquired reliability.

摘要： The invention relates to a method, comprising capturing an image of an object to be monitored at a first image capturing frequency by an image sensor of a machine vision system, transmitting said captured image data to an image data processing device and analyzing said received image data by said image data processing device, and wherein if the image data is detected to comprise a deviation, a trigger signal is transmitted for triggering an image sensor for reconfiguring it to capture an image burst and for transmitting the captured image burst data to said image data processing device for further analysis. The invention further relates to a machine vision system and a computer program product performing the method.

摘要： Integrated acoustic emission transducer apparatus and methods are described. An example integrated external preamplifier device includes a data extractor, a process variable determiner, a status indication determiner, and a presentation device. The integrated external preamplifier device receives an acoustic emission signal generated via an acoustic emission sensor operatively coupled to the integrated external preamplifier device. The data extractor extracts signal data from the acoustic emission signal. The process variable determiner determines process variable data based on the extracted signal data. The process variable data includes at least one of flow rate data, flow capacity data, flow area data, flow velocity data, mass accumulation data, or volume accumulation data. The status indication determiner determines status indication data based on the process variable data. The presentation device presents at least one of the process variable data or the status indication data at the integrated external preamplifier device.

摘要： Systems, computer-implemented methods, and non-transitory computer-readable medium having a stored computer program provide characterization of multiphase fluid flow (MPF) using approximate entropy calculation techniques to enhance measuring and monitoring of a flow regime in a segment of pipe for hydrocarbon-production operations. The systems and methods can be optimized using principal component analysis.
