摘要： The present invention relates to a method of detecting non-linear operation of a measuring device comprising an array of transducers and at least one receiver channel portion. The method comprises receiving measured signals through transducers of the array, processing the measured signals from the transducers through the receiver channel portion, combining the processed measured signals to produce a combined measurement signal, and detecting non-linearity of the combined measurement signal and non-linear operation of the measuring device by detecting saturation of the receiver channel portion. In one embodiment, the receiver channel portion comprises an analog-to-digital converter, a threshold is assigned to a digital output of the analog-to-digital converter, and saturation of the receiver channel portion is detected when the digital output of the analog-to-digital converter oversteps the assigned threshold. In one application of the invention, the measuring device is a non-destructive testing device.

摘要： A phased scanning method and phased scan eddy current array probe suitable for in-situ eddy current inspection of a structure without mechanical scanning. Overlapping subsets of the sensor elements within the array probe are dynamically connected in series and sequentially scanned to simulate the mechanical motion of a conventional array probe along a test surface. An algorithm to effectively balance the scan data is provided which comprises obtaining a reference scan at the time of probe installation, storing the measurement data from this reference scan in a memory device located within the probe, subtracting this reference curve from the curve obtained by all subsequent measurement scans to produce an adjusted curve, and processing the resulting adjusted curve through a high pass filter. A technique for verifying sensor elements of an eddy current array probe after permanent or semi-permanent installation against a test structure is also provided.

摘要： An X-ray fluorescence (XRF) instrument comprises a hand-held device housing which holds a radiation emitter configured to emit radiation directed at a test object and a radiation detector housed inside a chamber closed by a sealing window and configured to detect radiation of the test object, caused by the test object being exposed to the emitted radiation. A protective cover mechanism is affixed to the testing device and is configured to have a closed position which covers or blocks access to the sealing window to protect it from being broken or damaged by debris or other obstructions, and an open position which exposes the sealing window to allow the un-obstructed passage of radiation therethrough. The cover mechanism can be implemented variously, including by a pivotally mounted cover plate, an iris mechanism, a fan-like cover and the like. Debris can be detected variously, including by strain sensors, optical detectors and proximity sensors.

摘要： An enclosed electronic apparatus including a first continuous heat-transfer band forming at least a portion of the exterior surface of the enclosure, with continuous lateral edges on either side thereof, and mounting points on an internal side of the continuous heat transfer band to which a printed circuit board assembly is mountable. A printed circuit board assembly is mounted to the heat transfer band at the mounting points, with a thermally conductive portion forming a thermal path between a heat-producing electronic component of the printed circuit board assembly and the heat transfer band. A thermally conductive gasket between the printed circuit board assembly and the heat transfer band at the mounting points facilitates heat transfer. Opposing first and second enclosure portions seal the respective continuous lateral edges of the heat transfer band against penetration of fluid or debris. It is small, compact, lightweight, rugged and otherwise ergonomic for ease of use and protection from accidental impact caused by, for example, dropping the unit. The reliability of the system is improved because the internal electronic components are protected from moisture, dust, and other liquid or particle contaminants, all while maintaining an internal temperature that is lower than a maximum permissible operating temperature.
