  • Patent number: 10185833
    Abstract: The present invention provides for analysis of cyber-physical systems with relation to compliance requirements such as regulatory compliance, maintenance compliance and safety compliance. Generally, the invention provides for a set of paths from an initial state to an end state, and analyzing the paths to determine which ones contain a violation state. Based on the resultant paths test scripts are generated. Additionally, other compliance related procedures can be performed utilizing the path analysis.

  • Patent number: 10179846
    Abstract: A process of making magnetic microcapsules and a process of making polymeric material having self-healing properties. The process of making polymeric material having self-healing properties includes the steps of mixing microcapsules containing magnetic nanoparticles in a liquid polymer before curing, and guiding the microcapsules in the liquid polymer before curing by magnetic forces to a desired location or locations. Finally, the liquid polymer with the microcapsules is cured to a solid polymeric material.

  • Patent number: 10124298
    Abstract: A filter medium for oil-water separation, the filter medium being a composite, nanofibrous mat formed from electrospinning a single solution of one natural polymer and one synthetic polystyrene polymer together, where fibers of the natural polymer are reinforced by fibers of the synthetic polystyrene polymer. The nanofibrous mat may initially be hydrophobic and oleophilic, making it a suitable filter medium for separating oil from oil-water mixtures. The mat may be treated with one or more surfactants to change the surface wettability of the mat to hydrophilic and oleophobic for separating water from oil-water mixtures or to hydrophobic and oleophobic for separating oil and water droplets from wet gas.

  • Patent number: 10113777
    Abstract: An ambient water condensing apparatus that extracts water vapor from ambient air utilizing a thermoelectric device, a superhydrophobic and/or superhydrophilic radiating condensing surface and a heat sink for providing point of source irrigation or drinking water using conventional and/or sustainable energy supplies. The thermoelectric device is thermally coupled intermediate of the condensing surface and the heat sink, and in particular a cold side of the thermoelectric device is thermally connected to the condensing surface and a hot side of the thermoelectric device is thermally connected to the heat sink. The water condensing apparatus may also include at least one fan element that cools the heat sink and introduces additional air to the condensing surface. The thermoelectric device and the fan element may be powered by any suitable electrical energy source, such as by solar energy, wind energy or grid power.

  • Patent number: 9932807
    Abstract: A system and method for creating a controlled geyser well with sustained periodical production includes a cap (16) which prevents gas from entering a well tubing (14) while allowing liquid to enter and accumulate in the tubing, means for compressing the gas, and means for injecting the gas in the annulus so that the gas enters the bottom end of the well tubing (14), thereby creating a controlled geyser effect which blows out most of the liquid residing in the well tubing (14). The gas being compressed can be a produced gas or a supplied gas.

  • Patent number: 9865102
    Abstract: A system and method to preserve the integrity of data being extracted from an electronic data recorder (“EDR”) of an electronic control module (“ECM”) makes use of a forensic link adapter and, optionally, a sensor simulator (when ECM is out of the vehicle). The forensic link adapter has one or more first microprocessors and a first software means which prevent any message being sent by an external network from corrupting the previously recorded data measurements. The data measurements are then extracted, verified, and stored in a separate file. The sensor simulator has one or more second microprocessors, a second software means, and a bank of resistors that mimic sensors normally in communication with the ECM. The simulator “tricks” the ECM into thinking it is still in the vehicle by using the replicating vehicle system values the ECM normally sees when in the vehicle.

  • Patent number: 9645067
    Abstract: A wedge floatation device includes a bottom section and a sidewall positioned around a perimeter of the bottom section to contain a liquid within the wedge floatation device. The bottom section includes an outer portion and a plateau portion centrally positioned in the bottom section. The plateau portion is raised to a height above the outer portion and below a top edge of the sidewall. The plateau portion includes a groove that is substantially concentric with an outer perimeter of the plateau portion. The groove is designed to dampen the velocity of a liquid directed from the outer perimeter of the plateau portion to a center of the plateau portion. The bottom section further includes a transition portion extending between the outer portion and the plateau portion. The transition portion surrounds the outer perimeter of the plateau portion. The outer portion surrounds a perimeter of the transition portion.

  • Patent number: 9453398
    Abstract: A self-stabilizing gas lift valve apparatus for oil and gas production. The apparatus includes a valve body having at least one gas inlet in communication with an elongated gas chamber in the valve body. An impingement disk is moveable in the elongated gas chamber. A conical plug extends from the impingement disk with the conical plug having a valve plug extending axially therefrom. A conical cup terminates in a valve seat wherein the conical cup receives the conical plug therein. A valve closure force mechanism urges the valve plug toward the valve seat. Gas injected through the gas inlet provides a force upon the impingement disk to overcome the force of the valve closure force mechanism in order to open the valve plug. When the gas injected exceeds a predetermined force, the impingent disk is moved and a conical space between the conical plug and the conical cup is reduced.

  • Patent number: 9432282
    Abstract: This invention relates to the use of optimal (hyperspeed) paths for command and control (and other high priority) traffic and suboptimal (slower) paths for all other traffic in order to implement sophisticated network service differentiation and defensive techniques. A reaction time window is created to ensure that packets sent along hyperspeed paths can arrive sufficiently in advance of malicious traffic in order to alert network devices and initiate defensive actions. Assortments of defensive options are available to networks employing the invention and the inventive algorithms.

  • Patent number: 9417175
    Abstract: A method of determining solid particle surface energy includes placing solid particles in a container made of a very high surface energy material and pouring a liquid into the container. The method further includes tilting the container to drain out from the container a first subset of the solid particles floating at a top surface of the liquid and tilting the container to move the liquid away from a second subset of the solid particles that are below the top surface. The method also includes tilting the container to move the liquid back toward the second subset of the solid particles such that at least a portion of the second subset of particles floats at the top surface of the liquid and tilting the container to drain out from the container the portion of the second subset of the solid particles now floating at the top surface of the liquid.

  • Patent number: 9293759
    Abstract: A three-dimensional nanobattery formed by individually wiring nanostructured electrodes and combining them with an electrolyte. Short, capped nanotubes termed ‘nanobaskets’ are formed by sputtering coating onto nanoporous templates. Metallic nanowires are grown by electrochemical deposition from the nanobaskets and through the template, making electrical contact with each nanobasket electrode. The same procedure can be used to fabricate both a battery anode and a battery cathode. A thin layer of electrolyte is placed between the two nanobasket electrodes, and electrical contact is made through the nanowires.
