  • Patent number: 10359321
    Abstract: An integrated circuit and method are provided for accurately measuring the temperature of a die of the integrated circuit. Pairs of diodes are driven with different currents in order to generate a series of thermal voltages. The ADC measures the series of thermal voltages against an external reference voltage. Based on these thermal voltage measurements, the ADC calculates the die temperature. The different currents used to generate the series of thermal voltages are selected at specific ratios to each other in order to promote the ability of the ability of the ADC to calculate the die temperature using standard components and logic of an ADC. These thermal voltages are generated and measured using integrated components of the die for which a temperature measurement is being provided, thus reducing several sources of inaccuracies in conventional die temperature measurement techniques. Addition embodiments are provided for detecting defective diodes based on comparisons of the thermal voltage outputs.

  • Patent number: 10354195
    Abstract: Technical solutions are described for forecasting leaks in a pipeline network. An example method includes identifying a subsystem in the pipeline network that includes a first station. The method also includes accessing historical temporal sensor measurements of the stations. The method also includes generating a prediction model for the first station that predicts a pressure measurement at the first station based on the historical temporal sensor measurements at each station in the subsystem. The method also includes predicting a series of pressure measurements at the first station based on the historical temporal sensor measurements. The method also includes determining a series of deviations between the series of pressure measurements and historical pressure measurements of the first station and identifying a threshold value from the series of deviations, where a pressure measurement at the first station above or below the threshold value is indicative of a leak in the subsystem.

  • Patent number: 10352696
    Abstract: Ultrasonic transducers are imbedded into sacrificial metal coupons which are located in the vicinity of underground or aboveground structures, such as a pipe or tank, which allow for the measurement of the effectiveness of impressed current cathodic protection systems and can be used to determine the corrosion rate of the structure that is being protected. When excited by a pulser-receiver excitation pulse, the ultrasonic transducers can be used to determine the thickness of the coupon and its rate of change over time. The sacrificial metal coupon ultrasonic transducer assembly can be located in the vicinity of underground piping, under or inside of a tank, underground or underwater, or inserted into structures where absolute material loss values or material loss rate of change is being monitored.

  • Patent number: 10352915
    Abstract: A system for detection of a potentially irradiated object utilizing oxygen-17 (17O) quantities in a local atmosphere contacting the potentially irradiated object. The local atmosphere comprises nitrogen-14 (14N) and is typically air. The 17O quantity in the local atmosphere is determined through sampling using mass spectroscopy, nuclear resonance magnetic imaging, gas chromatography, or some other method. The 17O quantity in the local atmosphere is compared to a baseline quantity of 17O and deviations are treated as an indicator that a nuclear reaction converting 14N to 17O has occurred or is occurring. Typically the local atmosphere is isolated to some degree from an external atmosphere via some type of enclosure or container, and the external atmosphere provides the baseline quantity of 17O used for the comparison.

  • Patent number: 10352778
    Abstract: A composite active waveguide temperature sensor (10) incorporates a first, sensor portion (16) formed of an environment-resistant material such as ceramic coupled through an ultrasonically-transparent bond (20) to a second, waveguide portion (18) formed of an ultrasonically-transmissive material such as a metallic filament wire. By doing so, the sensor portion (16) may be positioned within a harsh environment and subjected to a temperature to be measured, and the waveguide portion (18) may be used to propagate ultrasonic energy to and/or from the sensor portion (16) to a location distal from the harsh environment for measurement of the temperature. The ultrasonically-transparent bond (20) between these portions (16, 18) limits attenuation of and the introduction of reflections and other noise to an ultrasonic signal propagated across the bond (20).
