Publication number: 20240159712Abstract: Systems, methods, and apparatuses are provided for examining a object under test. The apparatus can include a housing and a handle. The housing can include a sensing unit including a plurality of ultrasonic transducers, a circuit, a control unit, a display unit, and a communication interface. The circuit can include a memory, and a plurality of transceiver circuits coupled to the plurality of ultrasonic transducers. On receiving a triggering signal, the plurality of ultrasonic transducers emanates an ultrasonic beam to a object under test and can sense a reflected ultrasonic beam to generate a sensed signal. The control unit can process the received sensed signal to provide a processed data. The display unit can display the processed data. The communication interface can transmit the processed data to a monitoring device over a network. The handle has a frame configured to support the housing and allow the housing to rotate.Type: ApplicationFiled: November 11, 2022Publication date: May 16, 2024Inventors: Benjamin Hoemske, Johannes Buechler, Tobias Bruch

Patent number: 11874255Abstract: A method of ultrasonic inspection includes generating, by a phased array ultrasonic probe, a first ultrasonic beam propagating in a fluid and incident at a first angle to a target surface in response to receipt of first instructions. Ultrasonic echoes from first beam reflection by the target are measured and corresponding ultrasonic measurement signals are output. At least one environmental sensor measures at least one fluid property and outputs corresponding environmental signals. One or more processors determine a current speed of sound within the fluid from the ultrasonic measurement signals and environmental signals. Second instructions including a second angle are generated by the processors, based on the current speed of sound, when the current speed of sound differs from a predetermined speed of sound by more than a speed threshold. The ultrasonic probe generates a second ultrasonic beam at the second angle in response to receipt of the second instructions.Type: GrantFiled: July 8, 2022Date of Patent: January 16, 2024Assignee: Baker Hughes Holdings LLCInventors: Holger Charbon, Johannes Buechler

Patent number: 11719672Abstract: Systems and methods for improved ultrasonic testing are provided. An ultrasonic testing system can include an ultrasonic probe and an ultrasonic controller in electrical communication with the ultrasonic probe. The ultrasonic probe can include a plurality of ultrasonic transducers. The ultrasonic controller can be configured to generate one or more driving signals operative to cause the plurality of ultrasonic transducers to generate respective ultrasonic waves. A combination of the ultrasonic waves can form an ultrasonic waveform having one or more characteristics specified by the one or more driving signals. The ultrasonic controller can be further configured to change the one or more driving signals to adjust at least one characteristic of the ultrasonic waveform.Type: GrantFiled: May 4, 2021Date of Patent: August 8, 2023Inventors: Thomas Wuerschig, Johannes Buechler

Patent number: 8183493Abstract: A system for monitoring a weld operation is provided. The system includes an ultrasonic wave generator adapted to deliver an ultrasonic wave to a target material during the weld operation and an ultrasonic receiver adapted to receive the ultrasonic wave propagated through the target material. The system also includes a signal processor adapted to determine a quality level of a weld created during the weld operation by extracting data corresponding to a torsional mode from the ultrasonic wave and comparing the data to a profile that corresponds to an acceptable quality level.Type: GrantFiled: September 28, 2005Date of Patent: May 22, 2012Assignee: General Electric CompanyInventors: Thomas James Batzinger, Waseem I.

Patent number: 6286371Abstract: The invention concerns a monitor head for ultrasound control by pulse echo process, in particular for producing a brief ultrasound pulse, unipolar as far as possible, comprising an oscillator/transmitter (26) and an oscillator/receiver (32), each provided with electrodes (28, 30, 34, 36). The oscillator/transmitter (26) and the oscillator/receiver (32) are made of the same material. The oscillator/transmitter (26) and the oscillator/receiver (32) are arranged directly one behind the other, in the sound propagation direction, in particular flat-bonded one on the other.Type: GrantFiled: February 10, 2000Date of Patent: September 11, 2001Assignee: Krautkramer GmbH & Co.Inventors: Johannes Büchler, Manfred Rost, Torsten Niederdränk
