20130200889 | DEVICE AND METHOD FOR INDUCTIVE MEASUREMENTS - A method and device for nondestructive and noncontact detection of faults in a test piece, or electrically conductive particles in a liquid flow, moving passed the device, using eddy currents. The test piece or flow is exposed to periodic alternating electromagnetic fields. A periodic electrical signal is detected. The receiver coil signal is digitized with an A/D converter stage. A useful signal is produced from the digitized receiver coil signal with a signal processing unit, and the useful signal is evaluated with an evaluation unit for detecting a fault in the test piece or electrically conductive particles. When overdriving of the A/D converter stage by the receiver coil signal is ascertained by monitoring the curve shape of the digitized receiver coil signal, a part of the receiver coil signal truncated by the A/D converter stage is reconstructed using a mathematical approximation in the digitized receiver coil signal. | 08-08-2013 |

20080212065 | METHOD OF DETERMINING THE FLATNESS OF A FOUNDATION TO WHICH A BUILDING STRUCTURE, MACHINERY OR EQUIPMENT IS TO BE MOUNTED - A method for measuring flatness of a factory floor upon which machinery is to be mounted using a rotating laser beam that emits a rotating laser beam in an essentially horizontally plane. A photosensitive position sensor delivers an electrical pulse, which is identified by its timing and phase angle, during illumination by the laser beam. The phase angle and timing of these pulses constitute a measure of the position of the sensor in the coordinate system. Measurements are taken with the sensor positioned at each location at which the machinery is to be fixed to a factory floor. The method determines any differences in height between the measurement points and the amount, if any, that the floor needs to be adjusted at each mounting point to insure that a machine that is affixed to the floor these points will be level. | 09-04-2008 |
