20140312891 | Eddy Current Inspection Probe Based on Magnetoresistive Sensors - A device and method of eddy current based nondestructive testing of tubular structures made of electrically conductive materials is disclosed. The device includes a plurality of excitation electromagnets having an axis of symmetry and magnetoresistive sensors having an easy axis for magnetic field sensing; wherein the magnetoresistive sensors are arranged in a circular array on a single plane with the easy axis aligned radially with respect to the circular pattern and wherein the electromagnets are arranged in a circular pattern on both sides of the plane with their axes of symmetry being arranged parallel to the plane and orthogonal to radii of the circular pattern on which the electromagnets are placed. | 10-23-2014 |
20140012521 | Methods for Eddy Current Data Matching - A method of analyzing historic and current eddy current test probe data is disclosed. The method takes into account that the two data sets of data may not be an exact match in acquisition technique based on factors such as probe pull speed, direction, record leg or instrument configuration. The method includes the steps of aligning a first set of eddy current data to a second set of eddy current data based on prominent features found in both data sets; converting the first set of eddy current data to a modified first set of eddy current data to match the second set of operating conditions and; comparing the modified first set and the second set to find change over time. | 01-09-2014 |

20100185576 | METHODS FOR AUTOMATED EDDY CURRENT NON-DESTRUCTIVE TESTING ANALYSIS - A system and method for precisely detecting tubing flaws using a computer architecture that combines scalable processing power with an extensible array of detection and classification possibilities involving eddy current data analysis, as well as detection algorithms for pinpointing exact tubing regions and wherein these regions can be further divided into manageable segments for flaw analysis. Multiple classification tools utilized to discriminate detection and to precisely assign proper report codes to detect flaws repeatedly and accurately. | 07-22-2010 |
20100181791 | APPARATUS FOR AUTOMATED POSITIONING OF EDDY CURRENT TEST PROBE - An apparatus for automated inspection and repair of a tube sheet. The apparatus has a rotating gripper pod, comprising at least one tube gripper, a sliding body portion containing the gripper pod; a housing portion comprising at least one tube gripper and a tool head coupling. The tool head coupling swapably attaches to a eddy current test probe and at least one kind of tube repair tool. Novel, auto-locking tube grippers are also disclosed. A serial bus connects electronic modules within the apparatus and also connects the apparatus to an external controller. | 07-22-2010 |
