  • Patent number: 10598648
    Abstract: A non-destructive measurement apparatus and method for quantitatively measuring texture of a food snack is disclosed. The apparatus includes a laser generating tool, an ultrasound excitation device, an acoustic capturing device, an ultrasound capturing device and a data processing unit. The laser generating tool and the ultrasound excitation tool direct energy towards a food snack placed on a surface and produce an acoustic signal and an ultrasound signal. The data processing unit further comprises a digital signal processing module that processes the received acoustic signal and ultrasound signal. A statistical processing module further filters the acoustic signal from the data processing unit and generates a quantitative acoustic model for texture attributes such as hardness and fracturability. The quantitative model is correlated with a qualitative texture measurement from a descriptive expert panel. Texture of food snacks are quantitatively measured with the quantitative acoustic model.

    Abstract: The invention relates to an ultrasonic NDT sensor arrangement for inspecting surfaces of variable geometry of metal bodies. The sensor arrangement includes a housing with a hollow inner space and an opening, through which part of an incoming sound beam exits the housing to enter a metal body to be tested. An ultrasonic sensor is coupled to the housing such that it emits said incoming sound beam directly into said hollow inner space in a direction towards the opening. The said inner space of the housing is filled with a first coupling fluid which is water. The opening of the housing is closed with a closing member, which is made of a silicone material and which has a similar density and velocity of sound compared to the first coupling fluid.

A probe temporarily mounted close to the welded part on the surface of a metal plate emits ultrasonic waves from an oblique direction with respect to the boundary surfaces between a plurality of metal plates. At this time, the probe is temporarily mounted at the position where the incident ultrasonic waves pass through the welded part at the boundary between the plurality of metal plates in an oblique direction with respect to the boundary surface. Also, a display processing means displays the intensity of the refrected ultrasonic waves. Alternatively, the display processing means displays the details of the detection result estimated based on the intensity of the reflected ultrasonic waves.

A seal constrains flow of the liquid, for example preventing the liquid from surging out and flooding the inspection surface. The seal is not rigid and conforms to variations in the shape and unevenness of the inspection surface, thus forming a seal (although possibly a leaky seal) around the liquid. The probe preferably is held in place to produce optimum ultrasonic focus on the area of interest. Use of encoders can facilitate the production of C-scan area maps of the material being inspected.

  • Patent number: 7698944
    Abstract: Even in measurement in which the measurement time is limited to a short time, soundness of a spot weld zone can be evaluated with high reliability without being influenced by a positional deviation between an ultrasonic probe and the spot weld zone and the coupling condition between an ultrasonic probe and a metal sheet. Specifically, ultrasonic waves propagating along the surface of a test object are transmitted in a plurality of directions from a plurality of wave sending positions outside the spot weld zone in metal sheets (1a, 1b), and ultrasonic waves propagating along the surface of the test object with propagation paths not including the spot weld zone and ultrasonic waves propagating along the surface of the test object with propagation paths including the spot weld zone are received at a plurality of wave receiving positions outside the spot weld zone to evaluate the soundness of the spot weld zone.

  • Patent number: 7690259
    Abstract: Apparatus, systems, and methods for inspecting a structure are provided which permit inspection of uniquely shaped structures such as fuselage frames and shear ties. Probes may be constructed from rapid prototyping. Inspection may be performed manually and may use a portable function support system for delivering fluid couplant, controlling transmit and receive functions of the inspection sensors, and delivering immediate visual analysis for an operator. Integrated ultrasonic inspection apparatus, systems, and methods facilitate fast and efficient custom inspection devices and inspecting otherwise difficult-to-inspect structures.

  • Patent number: 7685878
    Abstract: Two transducers to be rotated around a circumferential location on a cylindrical body for structural testing of the body are carried on a mounting and drive apparatus including a magnetic attachment which can be manually brought up to a pipe from one side only for fixed connection to the pipe on that side at a position axially spaced from a weld. A collar shaped support for the pair of transducers is formed of a row of separate segments which wrap around the pipe from the one side and is rotated around the axis of the pipe to carry the transducer around the circumferential weld. The segments carry rollers to roll on the surface and are held against the pipe by magnets. The transducers are carried on the support in fixed angular position to track their position but in a manner which allows slight axial or radial movement relative to the pipe.

  • Patent number: 7637162
    Abstract: An apparatus for inspecting samples that may include a curvature that varies from sample to sample comprises a scanning element, a feed mechanism, and a pivot mechanism. The scanning element transmits and receives a signal to and from the sample as the sample passes by, thereby building an image or profile of the sample. The feed mechanism includes a drive motor coupled to a series of pulleys and belts that form an open-ended chain. The pulleys rotate when driven by the drive motor and are coupled to an array of rollers that rotate as well to propel a inspection sample past the scanning element. The pivot mechanism includes a series of primary and secondary links that also form an open-ended chain. The primary links are coupled to the rollers and the combination pivots in unison to form an arc that matches the curvature of the sample in order to maintain a fixed distance between the sample and the scanning element.

  • Publication number: 20090282924
    Abstract: A transducer arrangement for a nondestructive ultrasonic material testing system has a multiplicity of ultrasound transducers which can be moved linearly or swiveled along a trajectory curve. A multiplicity of ultrasound transducers can be aligned with a point of a specimen. If the size and the focal length of the transducers prohibit an annular or similar arrangement, the transducers are divided into smaller groups. They are then arranged so that every transducer passes over each desired focal point on the specimen during movement of the transducers along the trajectory curve.

  • Publication number: 20090282895
    Abstract: Calibration for a nondestructive ultrasonic material testing system is provided, the system having a multiplicity of ultrasound transducers which are linearly movable as a whole but are arranged fixed with respect to one another, for example mounted fixed in a single sensor holder. In order to achieve optimal alignment of the sensors with a specimen, the mechanical tolerance-induced offset between the beam direction of the ultrasound transducers and the ideal beam directions is found, for example with the aid of a mean straight line. It is then minimized by using the available degrees of freedom of the sensor holder, for example possible tilting of the sensor holder.

    Abstract: A method and apparatus for extracting an envelope curve of a spectrogram, for use in measurement of blood flow velocity by using spectral Doppler techniques, the method comprising steps of: processing RF ultrasound echo signals to obtain Doppler signals; performing spectral analysis on the Doppler signals, to obtain a corresponding power spectrum P(f); estimating a forward maximum frequency fmax+ and a backward maximum frequency fmax? for the Doppler signals at a predetermined moment, according to the power spectrum P(f) of the Doppler signals at the predetermined moment; determining a noise frequency range according to the two maximum frequencies, so as to estimate an average noise power E; and correcting the forward maximum frequency and the backward maximum frequency by using the average noise power E. With the method of the invention, influence from the SNR and bandwidth on the envelope curve may be reduced, so as to be useful for accurate computation of blood flow parameters.
