Abstract: 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.

Abstract: Methods and related systems are described for analyzing phase properties in a microfluidic device. A fluid is introduced under pressure into microchannel, and phase states of the fluid are optically detected at a number of locations along the microchannel. Gas and liquid phases of the fluid are distinguished based on a plurality of digital images of the fluid in the microchannel. Bi-level images can be generated based on the digital images, and the fraction of liquid or gas in the fluid can be estimated versus pressure based on the bi-level images. Properties such as bubble point values and/or a phase volume distribution ratio versus pressure for the fluid are can be estimated based on the detected phase states of the fluid.

Abstract: A method and system for magnetic locating resolves phase ambiguity. The system uses time-division multiplexed magnetic fields emitted from plural transmit coils. The magnetic fields are alternating fields at a carrier frequency, and the fields emitted from different coils in different transmit intervals have known phase relationship with one another as, for example where the alternating fields are coherent with one another. A receiver uses a plurality of sensor coils and derives plural components using the common phase reference or plural phase reference times having a known relationship. If the determinant of a matrix of the components has a first value, the phase information in the components is correct, and position and orientation are derived from the components. If the determinant has a second value, the phase information in the components is incorrect.

Abstract: A sensor has a transmitter module for transferring data via a line, the sensor receiving power via the line. At a point in time in which the sensor receives a first power level, it transmits the data for a first time interval. A second sensor which is connected to the line in parallel to the first sensor then transmits its data for a second time interval after the first time interval. A timing sequence control system in the two sensors which is triggered by the point in time of reception of the power ensures the subsequent transmission by the first and second sensor.

Abstract: A method for processing magnetotelluric data to identify subterranean deposits is provided for. The data comprise the amplitude of alternating magnetic or electrical fields recorded over time in at least two vector components at one or more locations in an area of interest. Amplitude pulses are identified in the data, wherein the pulses are time segments comprising an amplitude peak meeting defined threshold criteria in at least one vector component. The pulses are filtered at a set of predetermined frequencies to separate amplitude data at each frequency from the remainder of the amplitude data in the pulses. The frequencies correspond to subterranean depths over a range of interest. Differential impedances ?Z of the pulses at each frequency at each location are then statistically analyzed to determine a value correlated to the resistance of the earth at each frequency. The resistance values are indicative of the presence or absence of deposits at the corresponding subterranean depth at the location.

An automated arbitration scheme (22) is used to resolve conflicting system goals within survey resource constraints.

Abstract: Performance of an Enterprise Service Bus (ESB) is measured using a service deployed on a server. A client runs a compiler to add an aspect to an archive that provides a service when deployed to the server. The aspect causes the server to timestamp marked messages. The archive with the added aspect, which is the aspectized archive, is deployed to the server. The client measures the performance of the service deployed to the server by using timestamps of the marked messages returned from the server.

Abstract: A system for identifying a subset of sensors to sample to reduce the frequency of sensor access. The system determines rise times and records values for the sensors in the system. A time criticality of the sensors is determined based on the rise times. The system processes the sensors by first creating sensor subsets based on one or more constraints on the sensors. The system monitors the values of the sensors in a sensor subset and flags a sensor when it makes a determination that, prior to a next scheduled sampling of the sensor subset, the value of a sensor in the monitored sensor subset will exceed a threshold constraint. The system moves those flagged sensors to a second sensor subset which complies with the sensor's constraints.

Abstract: A method for detecting an operation malfunction of a leakage inspector causes the leakage inspector to execute a calibration process and an inspection process. The calibration process seals air inside a first device serving as a reference device and measures changes in pressure over two time intervals. The inspection process seals air inside a second device to be checked for a leak and measures changes in pressure over two time intervals. A ratio is calculated from these measured changes in pressure and the ratio is used to determine whether an operation malfunction occurs in the leakage inspector.

Abstract: First and second devices (7, 8) are configured to transmit and receive signals wirelessly and have first and second clocks respectively for determining signal transmission and arrival times. The first device transmits first and second signals (9, 10) and the second device transmits a third signal (11). By introducing a delay into the first signal, a thief may be able to fool the devices into thinking that they are closer than they really are. To help identify if a delay has been introduced into the first signal, the first device calculates a ratio of clock rates for the first and second clocks and determines whether the calculated ratio falls within a predefined range.
