  • Patent number: 10579777
    Abstract: Exemplary embodiments of the present disclosure relate to systems and methods for structural health monitoring in which a sensor network includes motes distributed with respect to a structure. The sensor network can utilize dynamic pattern matching to monitor and localize damage in the structure without modeling or solving equations of the engineered structure, and without ascertaining or separately accounting for extraneous and often-difficult-to-recognize or evaluate factors, such as of the environmental and stimuli-related variability type.

  • Patent number: 10578543
    Abstract: Conventional systems for monitoring pipe networks are generally not scalable, impractical in the field with uncontrolled environments or rely of static features of pipes that are vary depending on the pipes under consideration. The ideal sensor-ed monitoring systems are not economically viable. Systems and methods of the present disclosure provide an improved data-driven model to rank pipes in the order of burst probabilities, by including dynamic feature values of pipes such as pressure and flow that depends on network structure and operations. The present disclosure enables estimating approximate values for the dynamic features since they are hard to estimate accurately in the absence of a calibrated hydraulic model. The present disclosure also validates the estimated approximate dynamic feature values for the purpose of estimating bursts likelihood vis-a-vis accurate values of the dynamic metrics.

  • Patent number: 8949042
    Abstract: The present invention discloses an autonomous magnetic tomography method (MTM) and device for magnetographic identification and magnetographic analysis of mechanical flaws and defects along structures located deep in the sea or otherwise located underwater and further underground. The invention optimizes the inspection and maintenance processes of extended metallic constructions, e.g., pipelines. The device is based on the inverse magnetostrictive effect (i.e., the Villari effect)—the variation of a material's magnetic susceptibility under applied mechanical stress. The changes in magnetic susceptibility result in distribution of a magnetic field gradient along a structure's surface area, thus providing information about the presence and the value of the magnetic field anomaly at a given and precise location on the structure. The device and method is capable of autonomous and offline operation underwater at depths up to 1,500 meters below sea level.

The performance drift is then observed, whereby in monitoring said drift, trends may be determined and time or cycles to failure predicted.

    Abstract: A system includes multiple sensors configured to measure one or more characteristics of a rotating o reciprocating systems. The system also includes a monitoring system configured to monitor a health of the rotating system. The monitoring system includes an input interface configured to receive multiple input signals from the sensors. The monitoring system also includes a processing unit configured to identify a fault in the rotating system using the input signals. The monitoring system further includes an output interface configured to provide an indicator identifying the fault. The processing unit is configured to identify the fault by (i) generating a pressure-volume diagram from a fusion of the input signals and comparing the pressure-volume diagram to a previous diagram to determine changes in the diagrams and/or (ii) normalizing the input signals and using the normalized input signals to identify a defect and calculate a confidence level of the defect.

  • Patent number: 8483977
    Abstract: A method for locating defects in a target includes subjecting the target to an ultrasonic vibration. A first laser beam is then transmitted to the target and a reflection is received. A vibration signal is produced from the reflection that gives the target's response to the ultrasonic vibration. A digital image is produced of the target that includes the region of the first laser beam reflection. The digital images are overlaid with the vibration signal to provide overlaid data. The overlaid data is tested to determine a probability of the overlaid data being non-random. The probability is compared against a threshold to indicate a potential area of concern that may include defects.

  • Patent number: 8478548
    Abstract: A vibration data collection and rotating machinery fault diagnostic instrument includes a machine setup engine, a measurement engine, a diagnostic engine, a measurement user interface module, a machine setup user interface module, and a diagnostic user interface module. The machine setup engine requests and receives parameters about the machinery through the machine setup user interface module. The measurement engine requests and receives sensor placement locations through the measurement user interface module and keeps track of locations that have been measured and locations that still need to be measured. The diagnostic engine diagnoses machinery faults and presents the information to the user through the diagnostic user interface module using an intuitive graphical severity scale.

  • Publication number: 20130151171
    Abstract: The invention is directed to an ultrasonic inspection method, an ultrasonic test method, and an ultrasonic inspection apparatus that enable sizing to be executed even for a minute defect using an ultrasonic wave. A holder holds a transmitting probe for executing an angle beam method and a receiving probe for executing a vertical beam method. A motor and a guide rail form a movement mechanism for the transmitting probe and the receiving probe. In an ultrasonic test mode, the transmitting probe executes the angle beam method and transmits and receives an ultrasonic wave. In a sizing mode, the transmitting probe transmits an ultrasonic wave and the receiving probe receives this wave. A tip echo of a wave diffracted from a tip of a defect on a sample and a corner echo reflected from a corner of the defect are measured from a waveform received by the receiving probe.

  • Patent number: 8447530
    Abstract: A method for monitoring and diagnosing the health of a structure. The method includes providing a plurality of damage monitoring units each having at least one actuator, at least one sensor and a data collection device. The sensors are arranged and disposed to measure vibration produced by the actuator and provide a signal corresponding to the measured vibration to the data collection device. The actuator is activated and the vibration is measured with the sensor. The signal is compared to a reference signal and a damage index value is determined in response to the comparison between the signal and reference signal. The damage index value is transmitted for each vibratory path to a central processing device and the damage index values are analyzed for the plurality of damage monitoring units to determine the location of damage to the structure.

  • Patent number: 8436298
    Abstract: LC/MS data generated by an LC/MS system is analyzed to determine groupings of ions associated with originating molecules. Ions are grouped initially according to retention time, for example, using retention time or chromatographic peaks in mass chromatograms. After initial groupings are determined based on retention time, ion peak shapes are compared to determine whether ions should be excluded. Ions having peak shapes not matching other ions, or alternatively a reference peak shape, are excluded from the group.
