摘要： Methods and systems for material identification include generating a plurality of first fingerprints for a plurality of material sheets supplied by a supplier at a first step of processing the plurality of material sheets. Each first fingerprint in the plurality of first fingerprints represents a first attenuation measurement of each material sheet in the plurality of material sheets as captured by an array of transducers. Further, the methods and systems include generating a batch mask relating to the first step of processing the plurality of material sheets and based on the plurality of first fingerprints. The batch mask represents a signal correlation of the plurality of first fingerprints that is unique to the plurality of material sheets supplied by the supplier. A target material can be identified using the batch mask.

摘要： A rope, a system and a method for measuring one or more properties of a rope. A property evaluation system for ropes can be deployed for a number of different applications including, but not limited to, moving lines, e.g., crane or winch and static lines, e.g., mooring lines, stays, etc., to evaluate physical properties of the ropes and, in some cases, to help evaluate structural health of the ropes. A sheave assembly (10) may transmit a signal into a rope (14) to measure at least one property of the rope. At least one sensor (25) may be coupled to or assembled in the rope to measure at least one property of the rope.

摘要： A method and system for inspecting a rail by guided waves, the rail being instrumented by sensors. The method comprises the steps of receiving elastic wave measurements from one or more sensors, as a train passes, releasing energy as guided waves into the rail; and of determining a function representative of the impulse response of the rail and the sensors. Developments describe how to determine the existence, position and characterisation of a defect in the rail (e.g. fracture, incipient fracture, etc.), the use of inter-correlation analyses, correlation of the coda of correlations, Passive Inverse Filter, imaging techniques. Other aspects are described for exploring rail defects: sensor position and movement, acquisition time, sampling frequency, frequency filters, amplifications, techniques for learning during successive train passes, signal injection by transducers. Software aspects are described.

摘要： A computer-implemented method for determining a belt tension of a drive belt of a machine, based on a sound recording, including the steps of initiating a recording of sound, recording the sound during a primary time interval, discretising the sound into time samples, thereby obtaining a data set, filtering the data set, determining an average excitation spectrum, compensating for the average excitation spectrum, determining a confidence coefficient based on a highest and second highest extremum, and when the confidence coefficient exceeds a predefined value, determining the belt tension based on a frequency of the highest extremum.

摘要： Material properties between a wellbore and a casing having a partition separating respective domains inside and outside the casing are evaluated by disposing at least one ultrasonic transmitter and a plurality of ultrasonic receivers in longitudinally spaced-apart relationship alongside the partition inside the casing. The ultrasonic transmitter is activated to form ultrasonic waveforms comprising propagated quasi leaky-Lamb waves constituting flexural waves having symmetric and antisymmetric zero-order modes within the partition. A time-shift is applied to the received flexural waves so that the respective time-shifted waveforms corresponding to each of the flexural waves arrive at the same time. The time-shifted waveforms are clustered to form separate clusters respectively relating to a flexural wave part, and at least one post-flexural wave part which exposes characteristics that would otherwise be hidden behind more dominant features in the flexural wave and allowing determination of a material and geometry behind the partition.

摘要： Systems and methods for analyzing physical characteristics of a battery include arrangements of two or more transducers coupled to the battery. A control module controls one or more of the two or more transducers to transmit acoustic signals through at least a portion of the battery, and one or more of the two or more transducers to receive response acoustic signals. Distribution of physical properties of the battery is determined based at least on the transmitted acoustic signals and the response acoustic signals.

摘要： A signal processing unit configured to: cause a first ultrasound emitter, when attached to a wall of a vessel, to emit a first ultrasound test signal; receive, from at least one ultrasound receiver, when attached to the wall of the vessel, the first ultrasound test signal; detect a time of flight of the received first ultrasound test signal; and determine that an acoustic coupling of the first ultrasound emitter and a first ultrasound receiver of the at least one ultrasound receiver to the wall of the vessel is intact if the detected time of flight corresponds to a length of a path in the wall of the vessel from the first ultrasound emitter to the at least one ultrasound receiver.

摘要： According to one embodiment, a control method includes setting a transmission angle of an ultrasonic wave to a standard angle. The control method further includes transmitting an ultrasonic wave at the set transmission angle and detecting an intensity of a reflected wave from an object. The control method further includes calculating a tilt angle based on a gradient of the intensity. The tilt angle indicates a tilt of the object. The control method further includes resetting the transmission angle based on the tilt angle.
