20120006132 | PROBE HOLDER ADJUSTABLE TO CONFORM TO TEST SURFACES - Disclosed is an acoustic probe/wedge holder that facilitates the operation of holding and sliding the probe over often non-flat test surfaces. The probe/wedge holder is configured to allow the adjustment of the probe/wedge so that the footing of the probe holder and the test surface of the probe or wedge collectively match the surface of a test object, allowing the probe or wedge to have intimate contact with the test surface and the probe holder to be stably disposed on or gliding over the surface of the test object. The surface of the test object is often of non-flat surface, such as that of a pipe. | 01-12-2012 |
20120130653 | SYSTEM AND METHOD OF CONDUCTING REFRACTION ANGLE VERIFICATION FOR PHASED ARRAY PROBES USING STANDARD CALIBRATION BLOCKS - Disclosed is an ultrasonic phased array non-destructive inspection system that includes a PA probe, a conventional PA inspection unit and a refraction angle verification unit. The PA inspection unit is employed to emit ultrasonic angle beams into an AWS 11W Block and to receive a set of corresponding echo signals reflected from the calibration block and to provide time-of-flight (TOF) values corresponding to each angle beam. The refraction angle verification unit then provides a true angle for each of the angle beams based on the ultrasonic and geometric characteristics of the block and the measured TOF values. Other calibration blocks such as the DSC and Nayships blocks can also be used for this purpose. | 05-24-2012 |
20140028608 | METHOD OF MANIPULATING IMPEDANCE PLANE WITH A MULTI-POINT TOUCH ON TOUCH SCREEN - A touch screen is disclosed which responds to a user's touch for re-drawing, re-scaling, re-translating and re-positioning an impedance plane signal received from non-destructive testing equipment, such as an eddy current sensor. The impedance plane is manipulated by slidingne, two or more fingers simultaneously to an end position to effectuate a complete re-drawing operation of the image. | 01-30-2014 |
20140283611 | SYSTEM AND A METHOD OF ADAPTIVE FOCUSING IN A PHASED ARRAY ULTRASONIC SYSTEM - Disclosed in the present disclosure is a phased array system configured to ultrasonically inspect test targets complex surfaces while employing the surface profiling capability of phased-array linear and sectorial scans. Adaptive focusing is employed for inspecting the test target by using customized apertures according to the surface profiles to generate a plurality of beams that are evenly and thoroughly spaced along a scan line inside the test target. | 09-25-2014 |
20150039245 | SYSTEM AND METHOD OF NON-DESTRUCTIVE INSPECTION WITH A VISUAL SCANNING GUIDE - Disclosed is an inspection device and method of guiding an inspection probe according to a predetermined inspection plan. The device is couple with a probe which is to be moved according to the inspection plan on the test object, the device including an inspection guide unit having a guide control unit, a position encoding such as a 3-D camera and visual feedback eyewear. The method including facilitating a virtual display of the inspection plan onto the visual feedback eyewear, moving the probe following the virtual display of the inspection plan, sensing sensed probe positions in real time of the inspection using the 3-D camera and validating the sensed probe position against the inspection plan using the control module. Then the information of the step of validating, such as those spots at which the probe is moved out of the tolerance of the inspection plan, is displayed on the feedback eyewear. | 02-05-2015 |
