  • Patent number: 10788347
    Abstract: An estimate of interfacial areas between the liquid and gas, liquid and wall, and gas and wall in two phase flow is determined using a standard 2D sensor in a fashion to infer 3D information about the liquid/vapor profile when the sensor length is much longer than the diameter. Cross-sectional flow areas for the gas and liquid are also estimated as a function of the axial dimension of the sensor, and the centroid of the mass in the sensor element can also be estimated. An electric capacitance tomography (ECT) system creates tomograms of the flow inside a sensor, and estimates of 3D physical area information are produced from the tomograms.

  • Patent number: 10788532
    Abstract: Embedded processor-based self-test and diagnosis using the compressed test data is described for ICs having on-chip memory. Techniques for compressing the test data before the compressed test data is transferred to a device under test (DUT) are also described. A modified LZ77 algorithm can be used to compress strings of test data in which don't care bits are handled by assigning a value to the don't care bits according to a longest match in the window as the data is being encoded. The compressed test data can be decompressed at the DUT using a software program transferred by the automated test equipment (ATE) to the DUT with the compressed test data. Decompression and diagnostics can be carried out at the DUT using an embedded processor and the on-chip memory. Results from the diagnostics can be read by the ATE.

  • Patent number: 10753852
    Abstract: A computer-based corrosion/erosion module, communicatively coupled with a probe, estimates corrosion/erosion rates in a pipeline based on metal loss measurements. A High Integrity Protection System (HIPS), upstream of the corrosion/erosion module, includes at least two pressure-sensing elements, connected to the pipeline, for capturing pressure readings associated with inside pressures of the pipeline. The HIPS also includes at least two final elements configured to stop a flow of fluid through the pipeline. A logic solver, coupled with the corrosion/erosion module and the HIPS, is configured to automatically monitor mechanical integrity of the pipeline in real time using the captured pressure readings and estimated metal loss measurements. The logic solver determines a trip set point adjustment using the estimated metal loss measurements and provides the trip set point adjustment to the final elements.

  • Patent number: 10754063
    Abstract: In an embodiment, radar observation data for time points are received at an input layer of a rain rate prediction neural network. The radar observations are forward propagated via hidden layers of the network to determine rain rates for the time points. The rain rates are integrated over a time period, determined based on the time points, to determine a predicted rainfall amount. The predicted rainfall amount is compared with an actual rainfall amount, determined based on received rainfall measurements, to determine an error. If the error does not satisfy certain criteria, then the error is apportioned to each of the time points, the apportioned errors are back propagated via the hidden layers, and weights associated with nodes in the hidden layers are updated. The radar observation data is again forward propagated via the layers, multiplied by the updated weights, and used to determine new rain rates.
