    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.

    摘要: Disclosed is a portable non-destructive testing (NDT) instrument system that transmits spectrum data measured from a test material sample to a remotely located computer for computation of the sample's atomic element composition. The atomic element composition is subsequently transmitted back to the portable instrument for display to the operator in real time. The precision and accuracy of the compositional computation is improved by the greater processing power of the high performance remote computer. The operator of the NDT instrument may choose to use the remote computer to perform part or all of the compositional computation.

    摘要: A user configured measurement display system and method for a non-destructive testing device and instrument (NDT/NDI) with high input data rate is disclosed. The system and the method provide the means for NDT/NDI instruments display measurement values that satisfies user designated measurement criterion occurring during any measurement time intervals (MTIs). The present disclosure overcomes the shortcomings of conventional ways of picking and displaying measurement values at fixed MTIs, by which the values truly satisfying the measurement criterion that occurs at random MTIs (other than scheduled MTIs) are often skipped.

    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: A coplanar antenna system having a single-coil loop antenna provides both transmit and receive functions. The antenna operates in a tuned mode during transmitting and an untuned mode during receiving. Dead zone and transformer effect problems are virtually eliminated. The transmitter is highly efficient and the receiver is impulse noise immune.

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.
