摘要： A bonding layer evaluation system includes an elastic wave generation device configured to generate an elastic wave from a sample including a bonding layer; an elastic wave reflection body configured to reflect the elastic wave generated from the sample; a sample installation unit provided between the elastic wave generation device and the elastic wave reflection body; an elastic wave detection device disposed in a direction in which the elastic wave is reflected by the elastic wave reflection body, and configured to detect the reflected elastic wave; and a control device configured to evaluate a parameter related to the bonding layer. The control device evaluates the parameter related to the bonding layer by comparing the actual value of the elastic wave detected by the elastic wave detection device with a theoretical value of the elastic wave calculated based on a theoretical model related to the sample.

摘要： The invention disclosed herein generally relates to a device and methods to authenticate the composition of materials, including, but not limited to gold and silver coins and gold and silver bars. The invention stimulates the natural frequencies of the tested object and then compares them to a reference dataset to confirm its authenticity. It achieves this through use of a transducer that both vibrates the object and collects amplitude response, allowing for consistent and highly accurate analysis across a broad spectrum, including ultrasonic frequencies.

摘要： The present disclosure provides solutions to probing an interface. With a noninvasive measuring device provided in one embodiment of the disclosure, an acoustic wave whose frequency is higher than approximately 300 GHz is generated to propagate in a buffering film. With measuring the reflection from the interface of an object to be measured interfacing with the buffering film, it is possible in one embodiment of the disclosure that at least one physical property of the interface may be analyzed, preferably with approximately 0.3 nm resolution.

摘要： A dialysis machine (e.g., a peritoneal dialysis (PD) machine) can include a pressure sensor mounted at a proximal end of a patient line that provides PD solution to a patient through a catheter. During treatment, an occlusion can occur at different locations in the patient line and/or the catheter. Elastic waves may be generated at a pump that introduces (e.g., for fill cycles) or withdraws (e.g., for drain cycles) the solution into/out of the patient line. For example, when the solution is introduced or withdrawn suddenly, elastic waves travel distally down the patient line until they encounter the occlusion, and are then reflected back (e.g., toward the pressure sensor).

摘要： Apparatus is provided comprising a signal processor that receives signaling containing information about an acoustic signal swept and sensed over a frequency range in relation to a pipe; and determines information about the structure of the pipe based at least partly on two or more sub-frequency ranges that form part of the frequency range in the signaling received. The signal processor also receives the acoustic signal being transmitted to the pipe and corresponding signaling in the two or more sub-frequency ranges containing information about reflections of the acoustic signal back from the pipe; and determines information about the structure of the pipe based at least partly on a coherent mixing of the acoustic signal and the corresponding signaling in the two or more sub-frequency ranges using a coherent acoustic tomography technique. Alternatively, the signal processor also receives associated signaling in the two or more sub-frequency ranges containing information about associated resonance in a liner of a wall of the pipe and determines information about the liner of the wall of the pipe, based at least partly on the two or more sub-frequency ranges.

摘要： An embedded acoustic metamaterial lenses allows for ultrasonic beam-forming and high resolution identification of acoustic sources for structural health monitoring. The lenses design provides an alternative to conventional phased-array technology enabling the formation of steerable and collimated (or focused) ultrasonic beams by exploiting a single transducer. The ultrasonic beam can be steered by simply tuning the frequency of the excitation. Also, the embedded lens can be designed to achieve sub-wavelength resolution to clustered acoustic sources which is a typical scenario encountered in incipient structural damage.

摘要： A modal vibration analysis system and corresponding method is provided. A set of one or more exciters is coupled to a structure under test for generating vibrations in the structure. A set of sensors are coupled to the structure at multiple locations for sensing vibrations generated in the structure in response to the excitations. A controller receives sensor signals corresponding to the sensed vibrations from the set of sensors and provides drive signals to the set of exciters such that the sensor signals have a target output spectrum with specified characteristics in multiple designated frequency domains of the spectrum, characterized by a random phase for each frequency. Modal analysis processes digitized sensor signals with a Fast Fourier Transform conducted at two or more specified data sample rates to synthesize a spectrum containing data points with higher resolution for lower frequency range, and regular resolution for higher frequency range. From the multi-resolution spectra, natural frequencies and damping coefficients are determined at each mode, a mode shape at each natural frequency is computed using all measured data from all sensor locations.

摘要： A system for monitoring the condition of elongate structural elements, for example, railway rails, and a method of designing and manufacturing the system is disclosed. The method includes identifying and selecting suitable modes of propagation and signal frequencies that can be expected to travel large distances through an elongate structural element; designing a transducer that will excite the selected mode at the selected frequency; numerically modelling the transducer as attached to the elongate structural element; validating the transducer design by analysing a harmonic response of the selected mode of propagation to excitation by the transducer, and manufacturing one or more transducers for use in the system.
