  • Publication number: 20180299075
    Abstract: A system and method for controlling delivery of gas, including a gas pipeline network having at least one gas production plant, at least one gas receipt facility of a customer, a plurality of pipeline segments, and a plurality of control elements, one or more controllers, and one or more processors. The hydraulic feasibility of providing an increased flow rate of the gas to the gas receipt facility of the customer is determined using a linearized pressure drop model. A latent demand of the customer for the gas is estimated using a latent demand model. Based on the hydraulic feasibility and the latent demand, a new gas flow request rate from the customer is received. A network flow solution is calculated based on the new gas flow request rate. The network flow solution is associated with control element setpoints used by a controller to control one or more control elements.

  • Publication number: 20180299076
    Abstract: Controlling flow of gas in a gas pipeline network, wherein flow within each pipeline segment is associated with a direction (positive or negative). Minimum and maximum signed flow rates are calculated for each pipeline segment constituting lower and upper bounds, respectively, for flow in each pipeline segment. A nonlinear pressure drop relationship is linearized within the lower and upper flow bounds to create a linear pressure drop model for each pipeline segment. A network flow solution is calculated, using the linear pressure drop model, and includes flow rates for each pipeline segment to satisfy demand constraints and pressures for each of a plurality of network nodes to satisfy pressure constraints. Lower and upper bounds on the pressure constraint comprise a minimum delivery pressure and a maximum operating pressure, respectively. The network flow solution is associated with control element setpoints used by a controller to control one or more control elements.

  • Publication number: 20180299077
    Abstract: Controlling flow of gas in a gas pipeline network, wherein flow of gas within each of the pipeline segments is associated with a direction (positive or negative). Processors calculate minimum and maximum production rates (bounds) at the gas production plant to satisfy an energy consumption constraint over a period of time. The production rate bounds are used to calculate minimum and maximum signed flow rates (bounds) for each pipeline segment. A nonlinear pressure drop relationship is linearized to create a linear pressure drop model for each pipeline segment. A network flow solution is calculated, using the linear pressure drop model, comprising flow rates for each pipeline segment to satisfy demand constraints and pressures for each of a plurality of network nodes over the period of time to satisfy pressure constraints. The network flow solution is associated with control element setpoints used to control one or more control elements.

  • Patent number: 10102589
    Abstract: Unmanned aerial vehicles (UAVs) may facilitate insurance-related tasks. UAVs may actively be dispatched to an insured asset and the area surrounding an insured asset, such as with the policyholder or insured's permission and collect data related to the insured asset, such as images, video, audio, weather conditions, thermal signatures, wood and soil samples, etc., and transmit this data to a computing device. The computing device may be associated with and/or utilized by an insurance provider to perform insurance-related tasks, such as processing the data to determine an amount of risk associated with the insured asset. If the amount of risk has increased, the computing device may provide a recommendation to a mobile device of the policyholder on how to reduce the risk such that corrective action may be taken. Insurance discounts may be provided based upon following recommendations that mitigate risk.

  • Patent number: 10080594
    Abstract: A clip-on reducer tool assembly for seating a spinal fixation rod in a rod receiving implant, the tool assembly has an outer sleeve. The outer sleeve has a proximal end with a cylindrical portion having a threaded opening, a first leg extension extending therefrom to a distal end, and a second leg extension joined to the first leg extension at an intermediate location between the distal end and proximal end. The second leg extension extends from the distal end toward the proximal end to a lever end spaced from the cylindrical portion. The leg extensions at the distal end have grasping members to engage an outer surface of a rod receiving implant and a fulcrum proximally located near the intermediate location configured to enlarge the space between the leg extension at the distal end as the lever end is depressed inwardly relative to a longitudinal axis of the outer sleeve.

  • Publication number: 20180251946
    Abstract: In current highway transportation systems pavement markings guide vehicles along roads. A new system using metallic objects and electromagnetic sensing equipment would enable vehicles to better navigate roads. Metallic objects are placed on roadway surfaces in a similar fashion of existing pavement markings. The metallic objects are patterned to develop a code of information that is detectable using electromagnetic fields. When these fields are detected, the vehicles can be fully or semi-autonomously guided using the information communicated by the metallic filings.
