20080276711 | Device for Testing Material and Measuring Thickness on a Test Object Having at Least Electrically Conducting and Ferromagnetic Material Parts - A device is disclosed for material testing on a test object having at least electrically conducting and ferromagnetic material parts, the test object being provided with at least one technical surface, with at least one electromagnetic ultrasonic transducer array (EMUS) which is provided with a permanent magnet array or an electromagnet array and at least one eddy current coil arrangement. The at least one eddy current coil arrangement has at least one electrical strip conductor arrangement which is disposed at or parallel to a surface area of a rolling member which can be rolled on the technical surface of the test object, with the surface area rolling along with the rolling member during rolling. | 11-13-2008 |
20090139335 | Device and Method for the Material Testing and/or Thickness Measurements of a Test Object That Contains at Least Fractions of Electrically Conductive and Ferromagnetic Material - The invention relates to a device and a method for testing the material of a test object ( | 06-04-2009 |
20090217764 | METHOD FOR NONDESTRUCTIVE TESTING OF A TESTING BODY HAVING AT LEAST ONE ACOUSTICALLY ANISOTROPIC MATERIAL AREA - A method is described for nondestructive testing of a test body having at least one acoustically anisotropic material area using ultrasound. The method of the invention includes ascertaining or providing directionally specific sound propagation properties which describe an acoustically anisotropic material area; coupling ultrasonic waves into the acoustically anisotropic material area of the test body; receiving ultrasonic waves reflected from an interior of the test body using ultrasonic transducers; and analyzing ultrasonic signals generated by the ultrasonic transducers so that an analysis is performed which is directionally-selective on a basis of directionally-specific sound propagation properties of the anisotropic material. | 09-03-2009 |
20100064811 | METHOD AND DEVICE FOR AN IMAGING ULTRASONIC INSPECTION OF A THREE-DIMENSIONAL WORKPIECE - 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. | 03-18-2010 |
20100307252 | Method and Device for Ultrasound Testing - In a method and device for ultrasonic testing of a workpiece, a multiplicity of ultrasonic testing pulses are launched into the workpiece from a test surface thereof. At least two ultrasonic testing pulses are launched into the workpiece to be tested at launching points that are spaced apart from one another by a test step width measured along the test surface. A single measured value (Ī) assigned to a local point located in the workpiece is calculated on the basis of the received signals assigned to the at least two ultrasonic testing pulses. | 12-09-2010 |
20110050480 | Method and Device For The Spatially Resolved Detection and Reconstruction of ObjectsBy Means of Microwaves - A method and a device for the spatially resolved detection and reconstruction of objects using microwaves is described, in which at least one object to be detected is subjected to microwaves that are generated by a plurality of microwave antennas and microwave fractions reflected by the object are detected and converted into microwave signals that can be analyzed, based on which an analysis for the spatially resolved object detection is carried out. | 03-03-2011 |
