Abstract: A inspection system includes: a transmission unit that transmits a signal to inspect an inspection target object; a receipt unit that receives the signal from the transmission unit; and a totaling unit. The transmission unit and the receipt unit have a positional relationship that the transmission unit and the receipt unit sandwich the inspection target object. On the basis of at least one of radio-wave strength or signal waveform of the signal from the transmission unit and received by the receipt unit, the totaling unit determines whether or not there is a failure in the inspection target object. The inspection target object is resistors of a load-testing apparatus. A holding frame that holds the resistors is made of an insulator. The holding frame, the transmission unit, and the receipt unit are surrounded by a radio-wave-shielding member. The load-testing apparatus is provided with a grounding relay.

Abstract: An abnormality detection device and a fixing structure which are suitable for detecting an abnormality of a fastener such as a bolt or a nut are disclosed. An abnormality detection device detects an abnormality of a fixing structure, which includes a conductor and which fix steel plates to each other, and a spacer which includes an insulator and which is disposed between the steel plates and the washer. The abnormality detection device includes a transmission antenna that radiates electromagnetic waves to the fixing structure, a reception antenna that receives electromagnetic waves reflected by the fixing structure, and an abnormality detector that changes a frequency of the electromagnetic waves radiated from the transmission antenna to acquire frequency characteristics of standing waves received by the reception antenna. The abnormality of the fixing structure is detected by comparing the frequency characteristics with frequency characteristics in a normal state.

Abstract: A measuring device for determining the dielectric value of a medium in a phase-based manner comprises a measurement section which can be brought into contact with the medium, a signal generation unit for injecting a high-frequency signal at a defined frequency into the measurement section, and an evaluation unit designed to receive a corresponding reception signal after said high-frequency signal passes through the measurement section, to determine a phase shift between the high-frequency signal and the reception signal, and to determine the dielectric value of the medium on the basis of the determined phase shift. The measuring device also comprises at least one filter which transmits the frequency of the high-frequency signal and is arranged such that the received reception signal and/or the generated high-frequency signal is/are filtered. This ensures that the determined dielectric value is not distorted by noise caused by components or the environment.

Abstract: The present disclosure provides a method including: generating a definition of a buried pipeline and a tool, wherein the buried pipeline comprises a metal wall, wherein the tool comprises a transmitter and multiple receivers circumferentially positioned inside the metal wall but without contacting the metal wall; obtaining a solver configured to simulate a response on each of the multiple receivers; applying the solver based on, at least in part, the definition of the buried pipeline and the tool when the transmitter sends a known electromagnetic (EM) waveform; generating simulated responses on the multiple receivers from interacting with the wall of the buried pipeline; and based on, at least in part, the simulated responses, training an inference model configured to predict the wall-loss condition of a particular buried pipeline when presented with measurement data inside the particular buried pipeline.

Abstract: A method for identifying capsule defects in a tobacco filter includes measuring values for density and/or moisture content of the filter using a microwave measurement device. The measured values are compared with a threshold value and a presence of a capsule defect in the filter is determined if the measured valued undershoots the threshold value. A value for a degree of fluctuation of the measured values is determined at a region in front of a measurement location and/or behind the measurement location in which at least one measured value is below the threshold value. The value for the degree of fluctuation is compared with a predetermined capsule threshold value. The capsule defect comprises a broken capsule when the value for the degree of fluctuation exceeds the capsule threshold value, and the capsule defect comprises a missing capsule when the value for the degree of fluctuation undershoots the capsule threshold value.

Abstract: The present disclosure relates to a system for detecting and analyzing droplets of feedstock material being ejected from an additive manufacturing device. The system makes use of a split ring resonator (SRR) probe including a ring element having a gap, with the gap being positioned adjacent a path of travel of the droplets of feedstock material. An excitation signal source is used for supplying an excitation signal to the SRR probe. An analyzer analyzes signals generated by the SRR probe in response to perturbations in an electric field generated by the SRR probe as the droplets of feedstock material pass the ring element. The signals are indicative of dimensions of the droplets of feedstock material.

Abstract: Disclosed is an apparatus and method for evaluating a status of a refractory material in metallurgical vessels, including furnaces and ladles, wherein an external structure at least partly surrounding the refractory material impairs the propagation of radiofrequency signals. The apparatus and method are operative to identify flaws and determine the erosion profile and thickness of refractory material and the level or rate of penetration of molten material into the refractory material, using radiofrequency signals. The apparatus comprises an antenna embedded in the refractory material or positioned inside the chamber of the vessel designed to collect data associated with the propagation of radiofrequency signals transmitted by the antenna into the refractory material. Moreover, signal processing techniques allow determining the status of the internal wall of the vessel due to operational wear, age, and presence of flaws, cracks, corrosion, and erosion to improve the operational life and maintenance of the vessel.
