An inspection robot incudes a robot body, at least two sensors, a drive module, a stability assist device and an actuator. The at least two sensors are positioned to interrogate an inspection surface and are communicatively coupled to the robot body. The drive module includes at least two wheels that engage the inspection surface. The drive module is coupled to the robot body. The stability assist device is coupled to at least one of the robot body or the drive module. The actuator is coupled to the stability assist device at a first end, and coupled to one of the drive module or the robot body at a second end. The actuator is structured to selectively move the stability assist device between a first position and a second position. The first position includes a stored position. The second position includes a deployed position.
Method and device for detecting defects within a test object
A device and a method for detecting at least one defect in a test object (2). At least one test head (1) radiates an ultrasonic signal at different measuring points (MP) into the test object (2) with each point at an insonation or radiation angle (α) in order to ascertain multiple measurement data sets (MDS). The angle is constant for each data set (MDS). An analyzing unit (4) carries out an SAFT (Synthetic Aperture Focusing Technique) analysis for each ascertained measurement data set (MDS) using a common reconstruction grid (RG) inside the test object (2) in order to calculate an SAFT analysis result for each measurement data set (MDS). The analyzing unit (4) superimposes the calculated SAFT analysis results in order to calculate an orientation-independent defect display value (S.sub.RP) for each reconstruction point (RP) of the common reconstruction grid (RG).
PIPING INSPECTION APPARATUS
An ultrasonic transmission probe is arranged such that an ultrasonic wave transmitted from the ultrasonic transmission probe toward a pipe propagates in a thick part of the pipe, is at least reflected on the outer peripheral face of the pipe, and travels toward an inspection site on the pipe, and an ultrasonic reception probe is arranged to be symmetrical to the ultrasonic transmission probe with reference to the xz plane including the inspection site and perpendicular to the center axis of the pipe.
ULTRASONIC CONTAMINANT DETECTION SYSTEM
The invention generally provides a system and method for detecting, measuring, and/or classifying particulate and/or water contaminants in a fluid supply line, storage tank, or sump. Embodiments of the invention provide a contaminant detection apparatus with a detection chamber and a detection module. The detection chamber includes a housing with an internal fluid conduit and one or more acoustic transducers disposed in the housing. Alarms and/or automatic signaling may be included to shut off valves or pumps when contaminants are detected.
METHOD AND APPARATUS FOR DETERMINING THE DIRECTIONAL FREQUENCY RESPONSE OF AN ARRANGEMENT OF TRANSDUCER ELEMENTS
A method for determining the directional frequency response of an arrangement of transducer elements. The method comprises providing a simulation of locations of the transducer elements, in the spatial domain; providing a beamforming direction and a frequency range; converting the simulation of locations from the spatial domain into corresponding frequency response values in a spatial frequency domain, such that, for each frequency of a plurality of frequencies in the frequency range, a spatial frequency contour is defined, each of the spatial frequency contours intersecting at the origin; determining the frequency response by applying a transformation to the frequency response values for the provided beamforming direction and frequency range, translating the spatial frequency domain into a modified frequency domain, wherein the contours avoid intersecting; and outputting the frequency response. There is further provided a data processing device adapted to perform the method, a computer program, and a computer-readable medium.
METHOD FOR TESTING A STRUCTURAL COMPONENT OF A VEHICLE
A method for structural component crack testing comprising: a) identifying a structural component hole and inserting a probe thereinto; b) for different emission directions, automatically performing the following: b1) controlling a probe ultrasound beam emission; b2) measuring a probe signal; b3) if the measured signal amplitude is above a predetermined threshold: determining a distance between the probe and a structural component discontinuity point; recording a data set comprising at least the distance between the probe and the discontinuity point, together with a data element corresponding to the probe emission angular direction, c) automatically searching for data sets corresponding to characteristic discontinuity points, and consequently establishing a correspondence between the probe emission angular directions and an angular reference frame linked to the component; d) based on the recorded data sets, automatically determining the discontinuity point positions; e) determining a dimensional characteristic of a crack based on the discontinuity point positions.
ULTRASONIC TESTING FOR ADDITIVE MANUFACTURED COMPONENTS
A device for use in inspecting a test object is provided. The device can include a body including a first end and a second end. The second end can be opposite the first end. The device can also include a probe receiver located at the first end of the body. The probe receiver can be configured to receive an ultrasonic probe. The device can further include a coupling portion located at the second end of the body. The coupling portion can be configured to position the ultrasonic probe with respect to an axis of force transmission of a test object or normal to one or more material layers of the test object during an ultrasound inspection of the test object. Methods of forming the device and performing ultrasonic inspection of a test object with the device are also provided.
ULTRASOUND COUPLING MEDIUM DETECTION
A method of determining a status of ultrasound coupling medium for performing an ultrasound scan for providing an ultrasound image including plural scanlines (N.sub.l) is disclosed. In an embodiment, the method includes operating an ultrasound device to capture an image frame including plural scanlines (N.sub.l), each scanline having an associated sample set (s) of intensity values; processing a subset of the associated sample set (s) of values for each scanline to determine a first summation for each scanline; processing plural sets of corresponding intensity values from each of plural scanlines located within a range of a respective scanline to determine a set of difference values for each respective scanline; processing each set of difference values to determine a second summation for each scanline; and generating a status for the ultrasound coupling medium according to a relationship between each of the first summations and each of the associated second summations.
WATER WEDGE FOR FLEXIBLE PROBE
Disclosed is an ultrasonic inspection probe assembly comprising a water wedge and a flexible probe array assembly having a flexible acoustic module. The wedge is machined to match a test surface to be inspected and is configured to shape the acoustic module so that the active surface of the acoustic module is parallel to the test surface. Different wedges may be machined to match different test surfaces, but the same flexible probe array assembly may be used for all such surfaces.
Acoustic wave detection probe and photoacoustic measurement apparatus provided with the same
An acoustic wave detection probe includes a light projection section that emits measuring light to be projected onto a subject, an acoustic wave transducer disposed adjacent to the light projection section and capable of detecting an acoustic wave, an acoustic lens provided on a detection side of the acoustic wave transducer, and a housing accommodating the light projection section, the acoustic wave transducer, and the acoustic lens, in which the acoustic lens and a surface portion of the housing adjacent to the acoustic lens are formed to have an optical property in which the average diffuse reflection factor is 85% or more and the average absorption factor is 10% or less in a wavelength range of the measuring light.
