    摘要： A method and apparatus for effecting ultrasonic flaw detection of an object processes an echo signal received from the object being tested in at least three signal channels, wherein the echo signal is scaled to different degrees along each channel to increase and extend the dynamic range of an associated A/D converter system, in a manner which dispenses with the need for using numerous analog high pass and low pass filters and a variable gain amplifier. This reduces complexity and avoids performance limitations. The digital to analog converters sample the differently scaled input signal and a selection circuit selects the output of the digital output obtained from that analog to digital converter which has the highest gain, but which has not overflowed. The digital outputs are seamlessly merged to produce an output that can be displayed as a scan display which shows the location of faults.

    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： A GPS enabled datalogging system for a non-destructive test / non-destructive inspection instrument. GPS obtained location data is used to geographically stamp inspection data entries, which provides for more efficient and accurate data collection, organization, and analysis. The GPS enabled datalogging system also provides a method for detecting when the instrument has entered a specific inspection zone and performing location specific tasks to aid the operator in that inspection.

    摘要： An ultrasonic inspection system utilizes a tunable digital filter with 4X interpolation. The system is used for scanning objects to be tested and includes a transmit/receive device to generate a test signal and receive an echo signal. A signal processing circuit processes the echo signal with one or more digital to analog converters for converting an analog version of the echo signal to a digital echo signal in the form of streaming digital data which is stored in a memory. The data is stored at a first data rate and read out at the second, slower data rate. An averaging decimator receives and processes the data from the memory and supplies it to an IIR filter and subsequently to an FIR filter and ultimately to a box car filter to effect processing thereon which increases the perceived resolution of the data by a given factor, preferably by a factor of 4.
