Abstract: An apparatus and method for distributed physical parameter measurements of the surrounding environment is disclosed. The apparatus can include a waveguide with an elongated body configured with three gratings along the body where each of the three gratings is configured to fully or partially reflect an acoustic wave on the waveguide at a different frequency than the other gratings of the three gratings. Further, each of the three gratings can comprise discontinuities in the grating configured to reflect one or more frequencies of acoustic waves, and each of the discontinuities for each of the three gratings has an internal geometry configured according to fractions of an acoustic wave's frequency and corresponding wavelength.

Abstract: A gas analyzer uses continuous sonic signals through a conduit to determine the composition of a gas in the conduit. A transmitting transducer drives sonic signals at a fixed frequency and a second transducer receives the sonic signals. The phase shift between two signals corresponds to the speed of sound through the gas and is related to the composition of the gas. The electronic versions of these signals are processed by lowering, or dividing, the fixed frequency which expands the range of phase shift measurement and allows the determination of an expanded range for the gas composition. In an ozone generation system, the gas analyzer is highly suitable for determining the composition of gases derived from air as a gas of known composition and a calibration point.

Abstract: In a measuring arrangement for determining properties of a material to be extruded while an extrusion process is being carried out in an extruder, at least one extruder screw is rotatably mounted in a tubular guide in a barrel and is connected to a rotary drive. Material to be extruded is fed to the tubular guide at one end and is removed as finish-extruded material at an oppositely arranged discharge. Arranged at measuring positions at predeterminable defined intervals on the wall of the tubular guide along the longitudinal axis of the extruder screw are multiple first sound transducers, which are designed for the detection of sound waves that are generated during the extrusion process by the extrusion process as process noises and/or are emitted by a second sound transducer, arranged at one end of the tubular guide, in the direction of the longitudinal axis of the extruder screw and into the material to be extruded that is conveyed through a mixing chamber present in the tubular guide.

Abstract: The present disclosure is related to techniques for the inspection of joints and repairs in pipelines. In this scenario, the a method is provided for the inspection of joints in composite pipes and of composite repairs in metallic pipelines, comprising the steps of (i) emitting a series of acoustic wave pulses, at different frequencies, from a collar of acoustic transducers positioned at a predetermined distance from a joint or repair to be inspected, (ii) recording, in a time interval subsequent to the emission, echoes of wave displacements to the repair or joint in each of the transducers in the form of an A-Scan, and (iii) generating a flattened C-Scan image, through a CSM, for each frequency of pulse emission from the collar of acoustic transducers. The disclosure further provides a system for inspection of joints in composite pipes and of composite repairs in metallic pipelines associated with the provided method.

The system can also include an acoustic field receiver configured to be disposed proximate to, but without physically contacting, the underwater structure, where the acoustic field receiver is configured to receive resulting acoustic fields. The system can further include a controller that is configured to receive the resulting acoustic fields from the acoustic field receiver. The controller can also be configured to analyze the resulting acoustic fields signal. The controller can further be configured to detect, based on analyzing the resulting acoustic fields, a crack in the underwater structure.

Abstract: Object analysis comprising measuring a frequency-dependent natural oscillation behavior of the object by dynamically-mechanically exciting the object in a defined frequency range (f) by means of generating a body oscillation by applying a test signal, and detecting a body oscillation generated in the object on account of the exciting. Moreover, the method involves simulating a frequency-dependent natural oscillation behavior for the object by generating a virtual digital representation of the object, and carrying out a finite element analysis on the basis of the virtual representation comprising dynamically exciting, in a simulated manner, the virtual representation into a virtual frequency range for generating a virtual body oscillation, calculating the virtual body oscillation generated in the object on account of the exciting in a simulated manner, and deriving an object state on the basis of a comparison of the measured natural oscillation behavior and the simulated frequency-dependent natural oscillation behavior.
