Patent number: 10883968Abstract: An ultrasonic sensor assembly includes a flexible supporting material that has flexibility configured for allowing bending of the supporting material to conform to a cylindrical shape of a pipe. The assembly includes a plurality of operable sensor elements arranged in a matrix formation upon the flexible supporting material. The matrix formation includes a plurality of rows of the sensor elements and a plurality of columns of the sensor elements. The flexible supporting material is configured for placement of the columns of the matrix formation to extend along the elongation of the pipe and the flexible supporting material is configured for placement of the rows of the matrix formation to extend transverse to the elongation of the pipe. The flexible support material is configured to flex for positioning the sensor elements within each row in a respective arc that follows a curve of the cylinder shape of the pipe.Type: GrantFiled: February 7, 2020Date of Patent: January 5, 2021Assignee: General Electric CompanyInventors: Wolf-Dietrich Kleinert, Mark Howard Feydo

Patent number: 9639056Abstract: Systems and methods are disclosed herein in which multi-level square wave excitation signals are used instead of or in addition to fully-analog excitation signals to drive an array of transceiver elements to create a sound field. Use of multi-level square wave excitation signals produces acceptable transceiver output with reduced complexity, cost, and/or power consumption as compared with use of fully-analog excitation signals. In addition, use of such signals facilitates system implementation using application-specific integrated circuits (ASICs) and is not as restricted in voltage level and speed. At the same time, the benefits and applications of fully-analog excitation signals (e.g., acoustic holography, beam superposition, signal-to-noise ratio (SNR) improvements, suppression of parasitic modes, increased material penetration, potential for coded pulsing algorithms and suppression of side lobes in ultrasonic field) can still be achieved with multi-level square wave excitation signals.Type: GrantFiled: September 17, 2013Date of Patent: May 2, 2017Assignee: GENERAL ELECTRIC COMPANYInventors: Stephan Falter, James Norman Barshinger, Dirk Lange, Mark Howard Feydo, Werner Lammerich

Patent number: 9404896Abstract: An ultrasonic sensor assembly for a test object includes a sensor array having a plurality of sensor elements. The sensor elements detect a characteristic of the test object. The sensor elements are arranged in a matrix formation. Each of the sensor elements includes a transmitter for transmitting a signal and a receiver for receiving the transmitted signal. The sensor array has a curvature that substantially matches a curvature of the test object. A method of detecting characteristics of the test object is also provided.Type: GrantFiled: November 19, 2012Date of Patent: August 2, 2016Assignee: GENERAL ELECTRIC COMPANYInventors: Wolf-Dietrich Kleinert, Mark Howard Feydo

Patent number: 9207213Abstract: An ultrasonic sensor assembly detects a characteristic of a pipe. The ultrasonic sensor assembly includes first and second transducer rings spaced apart along a length of the pipe. Each of the first and second transducer rings can transmit a first wave longitudinally along the pipe and receive a reflection of the transmitted first wave from the characteristic. The first transducer ring can use results related to the reflection of the transmitted first wave to guide a second wave along the pipe that is received by the second transducer ring. Methods of detecting a characteristic of the pipe are also provided.Type: GrantFiled: January 7, 2013Date of Patent: December 8, 2015Assignee: GENERAL ELECTRIC COMPANYInventors: James Norman Barshinger, Mark Howard Feydo
