摘要： A method and system related to phased array ultrasonic systems identifies faults in individual element on a regular basis. The method and system are based on a simple approach of calculating energy levels in response signals from each individual element and then identifying any discontinuities or unexpected drops in energy levels sensed during a typical phased array operation, by comparing responses for individual transducer elements to the group response.

摘要： A multiple mode digitization system for a non-destructive inspection instrument which makes use of a multiplexing circuit and a single set of analog to digital converters to efficiently digitize analog test signals from a plurality of inputs. In the preferred embodiment, each of the analog to digital converters in the system is driven with an independent and separate clock signal, allowing for propagation delay compensation among the plurality of test signals as well as interleaved sampling such that custom sampling rates can be used for each input without the need for more than one clock frequency. In an alternate embodiment, phase adjustments on the sampling clocks are used only for interleave sampling, and digital filters are used to provide signal propagation delay compensation.

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： 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： Alerting a user of a material inspection device to a change in thickness of a material being inspected is disclosed. A thickness offset is determined from calibration information. The calibration information identifies a time of flight of a pulse through a reference sample similar in composition to a material to be inspected. The thickness offset indicates when a thickness of a material being inspected differs from a thickness of the reference sample. A calibration thickness alarm is set, the calibration thickness alarm corresponding to the thickness offset. A change in thickness of the material being inspected is detected. The calibration thickness alarm is engaged to alert the user of the inspection device of a detected change in thickness of the material being inspected.
