  • Patent number: 10506307
    Abstract: An apparatus and method for remotely monitoring water usage in real time utilizes a sensor attached to a water meter. The sensor monitors water flowing through the meter by analyzing the water meter's magnetic coupling and processes the data to correlate it to real time flow rates. Data is transmitted through a base unit to remote storage and consumers may access the data with application software installed on electronics such as smartphones and tablets. Four components are combined to allow the real time monitoring of water utilization.

  • Patent number: 10473270
    Abstract: Leak detection user interfaces are provided. In general, a user interface for a pipeline management system can be configured to provide information regarding one or more pipelines to a user. The information can include data gathered using one or more sensors sensing various parameters. The information on the user interface can include results of analysis of the gathered data, such as notifications that the gathered data indicates an anomaly with a pipeline. The notifications of anomalies can be provided on the user interface in real time with the data analysis. Accordingly, the user can trigger one or more corrective actions such as notifying maintenance personnel local to a location of the identified anomaly, remotely controlling the pipeline with the anomaly to close valve(s) and/or other equipment to prevent fluid flow in the pipeline in the area of the detected anomaly, etc.

  • Patent number: 10459098
    Abstract: A system and method are provided for automatically correlating geologic tops. The system receives well logs from different well bores and one or more user seed picks identifying a well top to be correlated. Each of the seed picks is added to a priority queue ordered by each pick's confidence. User selected picks are assigned the highest level of confidence. The system performs correlation by selecting a window of well log data about a user's manual pick, selected from the top of the priority queue, and then finding the best optimal match with a corresponding window in a neighboring wellbore. That new pick is then estimated in the target well using a correlation function. A quality value and a confidence value may then be calculated for each pick using some correlation function, for example dynamic time warping, and added to the priority queue according to the confidence value.

  • Patent number: 10416660
    Abstract: A hybrid data collection and analysis infrastructure combines edge-level and cloud-level computing to perform high-level monitoring and control of industrial systems and processes. Edge devices located on-premise at one or more plant facilities can collect data from multiple industrial devices on the plant floor and perform local edge-level analytics on the collected data. In addition, the edge devices maintain a communication channel to a cloud platform executing cloud-level data collection and analytic services. As necessary, the edge devices can pass selected sets of data to the cloud platform, where the cloud-level analytic services perform higher level analytics on the industrial data. The hybrid architecture operates in a bi-directional manner, allowing the cloud-level and edge-level analytics to send control instructions to industrial devices based on results of the edge-level and cloud-level analytics.

  • Patent number: 10386258
    Abstract: In some embodiments, computer-implemented systems/methods detect and/or quantify changes in emission rates of gas emission sources (e.g. natural gas leaks originating from underground distribution pipelines) using data from multiple vehicle-based measurement runs. Exemplary described methods aim to address the observation that large (e.g. 10×) changes in gas concentrations away from a source may be observed even in the absence of significant changes in source emission rate, due to changes in wind or other atmospheric conditions and local spatial variations in gas concentrations. Described methods are useful for identifying large increases in the emission rate(s) of known sources, for example due to frost heave or other dislocations. Multiple runs are performed along the same survey path in closely-related conditions (e.g. same time of day, same lanes), and a statistical test (e.g. a Kolmogorov-Smirnov test) is used to identify changes in concentration reflecting changes in emission rates.

  • Patent number: 10337477
    Abstract: An internal combustion engine fuel supply system includes a first fuel tank, a separator, and circuitry. The first fuel tank is to store fuel. The separator is connected to the first fuel tank to separate the fuel supplied from the first fuel tank into a high octane fuel and a low octane fuel which are to be supplied to an internal combustion engine. The high octane fuel has a first octane number. The low octane fuel has a second octane number lower than the first octane number. The circuitry is configured to determine whether fuel has been supplied to the first fuel tank, and to operate the separator to separate the fuel into the high octane fuel and the low octane fuel when it is determined that fuel has been supplied to the first fuel tank.

  • Patent number: 10309861
    Abstract: Methods and systems are provided for intelligently detecting pipeline small leaks and thefts. In the Energy Flow Line Method, measured changes in flow data at both ends of the pipeline are monitored and analyzed to detect a leak or a theft. The energy wave front speed and the unsteady flow mathematical model of the subject pipeline is used to calculate leak details. In the Filtered Pressure Waves Method, the measured pressure data at both ends of the pipeline is monitored and analyzed. Pressure waves that do not originate at the ends of the pipeline are selected. Two travelling time windows are applied to those candidates, and the candidates are processed within each window. Leaks, thefts and their details are obtained if the detected leak locations meet the criteria. The Enhanced Filtered Pressure Waves Method, provides the leaked amount and verifies the leak and the leak location to avoid false alarms.
