In one case, a gas supply system is provided which includes a gas panel defining an enclosure that includes a gas dispensing manifold. Gas flow through the gas dispensing manifold is regulated using solenoids. The gas supply system also includes a redundant control system that is electrically connected to the solenoids. The redundant control system is configured to send actuation signals to the solenoids to allow or prevent gas from flowing through the gas dispensing manifold. The gas supply system further includes a communications module that allows the redundant control system to monitor multiple gas panels. The monitoring includes receiving feedback from gas cabinet components regarding component operational status, and also transmitting actuation signals from the redundant control system to the gas panel.

  • Patent number: 10330508
    Abstract: A method of ultrasound flow metering includes applying a first and second pulse train to an ultrasound transducer pair (T1, T2) positioned for coupling ultrasonic waves therebetween. Responsive to the first pulse train applied to T1, T1 transmits an ultrasonic wave received as received ultrasonic wave (R12) by T2 after propagating through fluid in a pipe. Responsive to the second pulse train applied to T2, T2 transmits an ultrasonic wave received as received ultrasonic wave by (R21) T1 after propagating through the fluid. During the pulse trains, R12 and R21 build up in amplitude to provide excitation portions. The pulse trains are terminated, so that R12 and R21 decay as a damped free oscillation. Windowing is applied to R12 and R21 to generate windowed portions. A signal delay between t12 and t21 (?TOF) is calculated using only windowed portions, and a fluid flow is calculated from the ?TOF.

  • Patent number: 10317261
    Abstract: Systems and methods for estimating a flow rate through a device are provided. One or more pressure sensors measure a plurality of pressure differentials across a tested device. A temporary flow rate sensor measures a plurality of flow rates through the tested device. Each of the measured flow rates corresponds to one of the measured pressure differentials. A regression model trainer generates regression coefficients for a flow rate model using the measured pressure differentials and corresponding flow rates. A flow rate estimator uses the flow rate model to estimate a flow rate through a tested or untested device as a function of a measured pressure differential across the tested or untested device.

  • Patent number: 10288548
    Abstract: A method and apparatus for estimating a fouling state of a heat exchanger of an aircraft. Training sensor measurements are obtained of a parameter related to operation of the heat exchanger and a wavelet transform is applied to the training sensor measurements to obtain wavelet data. Data reduction is performed on the wavelet data to obtain representative features indicative of the training sensor measurements. A classifier is then trained to assign suitable fouling classes to the representative features. The trained classifier is used on testing sensor measurements from the heat exchanger to assign a fouling class to the testing sensor measurements in order to estimate the fouling state of the heat exchanger.

  • Patent number: 10215638
    Abstract: A system and method for non-destructive, in situ, positive material identification of a pipe selects a plurality of test areas that are separated axially and circumferentially from one another and then polishes a portion of each test area. Within each polished area, a non-destructive test device is used to collect mechanical property data and another non-destructive test device is used to collect chemical property data. An overall mean for the mechanical property data, and for the chemical property data, is calculated using at least two data collection runs. The means are compared to a known material standard to determine, at a high level of confidence, ultimate yield strength and ultimate tensile strength within +/?10%, a carbon percentage within +/?25%, and a manganese percentage within +/?20% of a known material standard.

  • Patent number: 10175078
    Abstract: A holder is mounted on a U-shaped curved tube portion of a measurement tube formed of a synthetic resin, and wing-shaped strips having a plate shape protrude outward from the holder. Distortion caused by a Coriolis force which depends on a flow rate is generated symmetrically with respect to a center line passing through a distal end of the curved tube portion and parallel to an outbound tube and an inbound tube. Therefore, the outbound tube and the inbound tube are twisted about the center line of the holder, and an amount of distortion is enhanced by the wing-shaped strips under the principle of leverage for detection.
