  • Publication number: 20240094423
    Abstract: Aspects provide for methods that successfully evaluates multiple compressional and shear arrival events received by a sonic logging tool to evaluate the presence of structures, such as shoulder beds, in downhole environments. In particular, the methods described herein enable automated determination of properties of laminated reservoir formations by, for example, enabling the automated determination of arrival times and slownesses of multiple compressional and shear arrival events received by a sonic logging tool.

  • Publication number: 20240076563
    Abstract: Provided in one embodiment is an improved and more flexible process for preparing a finished base oil or a white oil product comprising passing a dewaxed base oil product to a distillation column and separating the dewaxed base oil product into fuel and base oil product streams. The base oil product streams are tested to determine if they meet desired specifications. Base oil product streams that meet the desired minimum base oil specifications are passed to a hydrofinishing reactor to prepare a white oil product, or passed to direct sale.

  • Patent number: 11913112
    Abstract: Processes for depositing silicon-containing films (e.g., silicon, amorphous silicon, silicon oxide, silicon nitride, silicon carbide, silicon oxynitride, silicon carbonitride, doped silicon films, and metal-doped silicon nitride films) are performed using halidosilane precursors. Examples of halidosilane precursor compounds described herein, include, but are not limited to, monochlorodisilane (MCDS), monobromodisilane (MBDS), monoiododisilane (MIDS), monochlorotrisilane (MCTS), and monobromotrisilane (MBTS), monoiodotrisilane (MITS).

  • Patent number: 10510078
    Abstract: A payment processing system continuously processes transactions. A group of transactions satisfying criteria within a recent measurement window are extracted from transaction data. A second group of transactions satisfying the criteria within a past baseline window are also extracted. An attribute of transactions is selected for analysis and a risk metric value is calculated for transactions in the measurement window having a particular attribute value. The same risk metric is used to calculate a baseline value for transactions in the baseline window having the same attribute value. The baseline value may be normalized and adjusted. The risk metric value is compared to the baseline value and an alert is generated if the risk metric value is greater. Any of a variety of risk metrics are used. Total dollar amount and total order count from the measurement window compared to similar from the baseline window are also used to inform the alert.

  • Patent number: 10496992
    Abstract: A payment processing system continuously processes transactions. Upon arrival, in real-time, a transaction is parsed and each entity is used to retrieve other previous transactions associated with that entity in order to build a link analysis web. Iteratively, each entity in the retrieved transactions is used to retrieve other associated transactions, etc. Before retrieval of associated transactions, each entity is checked whether it appears in a bypass table. If so, that entity is not used to retrieve transactions. Once built, transactions and entities within the link analysis web are analyzed to determine whether the current transaction is fraudulent. Off-line or online, risk metrics such as address mismatch rate, bank decline rate, ticket decline rate and new payment device rate, along with the proportion of a linked entity is used to determine whether that linked entity is erroneous and should be placed into the bypass table and excluded from the web.

  • Publication number: 20160091104
    Abstract: Methods and apparatus for a safety shutoff valve generally comprise a valve lever coupled to a pipe, a shifting mechanism coupled to the valve lever, which causes the valve lever to be biased to move to and stay in the closed position, a release bar to hold the valve lever in the open position, a release mechanism, and an actuator. The actuator is a nickel-titanium alloy wire. The release bar holds the valve lever in the open position, the release bar being held in place by the release mechanism coupled to it. The release mechanism is coupled to nickel-titanium alloy wire, which extends along the pipe away from the valve apparatus. When heated, by a fire, for example, the nickel-titanium alloy wire contracts, pulls the release mechanism away from the release bar, and allows the valve lever to automatically move to and remain in the closed position, cutting off the flow of oil, or other fire fuel, to the fire.
