Patents by Inventor Ludwig von Bernus

Ludwig von Bernus has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8365600
    Abstract: The invention is a method using ultrasound for non-destructive examination of a test body, whereby ultrasonic waves are coupled into the test body with one ultrasonic transducer or a multiplicity of ultrasonic transducers and the ultrasonic waves reflected inside the test body are received by a multiplicity of ultrasonic transducers and converted into ultrasonic signals. The ultrasonic signals detected in the single measurement periods are individually stored and are accessible for off-line evaluation after termination of the measurements. Application of corresponding reconstruction algorithms permits subsequent synthetization of any desired ultrasonic coupling-in angles and focussing into the volume region of the test body from the stored ultrasonic signals without requiring any additional ultrasonic measurements.

  • Publication number: 20120036934
    Abstract: The invention relates to a method for the non-destructive examination of a test body by means of ultrasound, whereby ultrasound waves are injected into the test body by means of one or more ultrasound transducers and ultrasound waves reflected inside the test body are received by a plurality of ultrasound transducers and are converted to ultrasound signals. The ultrasound signals are detected in individual measurement intervals and are stored individually and are accessible to offline evaluation after termination of the measurements. The inventive method allows to subsequently synthesize any acoustic irradiation angle and focusing in the physically possible volume range of the test body from the stored ultrasound signals by using corresponding reconstruction algorithms, thereby eliminating the need for additional ultrasound measurements.

  • Patent number: 8109147
    Abstract: A method for an imaging ultrasonic inspection of a three-dimensional workpiece, in which ultrasonic waves are coupled into the workpiece with at least one ultrasonic transducer and ultrasonic waves reflected within the workpiece are received by ultrasonic transducers and converted into ultrasonic signals forming the basis of the non-destructive imaging ultrasonic inspection.

  • Patent number: 4687992
    Abstract: Defect detection in testing pipes, particularly in heat exchangers of nuclear reactors by means of eddy current in which interference influences due to the design are suppressed by measurements with different frequencies and the frequencies interlinked to give a signal only if there is a defect indication.
