  • Patent number: 10875794
    Abstract: For changing a property of a polar liquid a device comprising a signal generator and a transducer is provided adjacent to the liquid or at least partially immersed therein. The signal generator provides an alternating electrical signal to the transducer, wherein the electrical signal is of a frequency and an amplitude to affect the transducer to produce an alternating magnetic field having a magnetic flux density so as to change the property of the polar liquid, wherein a portion of the magnetic field penetrates the liquid, having an effect thereon and providing a change in the property of the liquid at a distance of at least 1 meter from the transducer. The property is a gas exchange rate and the change is at least 5%, or the property is surface tension and the change is at least 1%, or the property is viscosity and the change is at least 0.5%.

  • Patent number: 10808510
    Abstract: A power generation system includes one or more micro-turbine electric generators (“MTEGs”). The MTEGs include a housing having an inlet for receiving pressurized gas and an outlet for releasing expanded gas. The MTEGs also include a rotor, a user-replaceable nozzle for directing pressurized gas over blades of the rotor, and a stator for generating alternating current (“AC”) responsive to rotation of the rotor. The power generation system also includes a programmable logic controller (“PLC”) coupled to the MTEGs that operates flow control valves (“FCVs”) coupled to the MTEGs to modulate the flow of gas to the MTEGs to generate output power suitable to support an electrical load. The system also includes power conversion circuitry configured to convert AC generated by the MTEGs to direct current (“DC”) and to provide the DC to an electrical load. The system also includes a skid for mounting multiple and MTEGs and FCVs.

    Abstract: Systems and methods relating to patch antennas. A patch antenna has a substrate, a resonant metal plate at one side of the substrate, and a ground plane at the other opposite side of the substrate. Two feed pins are used to couple the antenna to other circuitry. The feed pins pass through the substrate and holes in at the ground plane. The feed pins are physically disconnected from both the resonant metal plate and the ground plane. The feed pins are capacitively coupled to the resonant metal plate to provide an electronic connection between other circuitry and the patch antenna.

  • Patent number: 10763021
    Abstract: For changing a property of a polar liquid, a transducer including a solenoidal coil is disposed at least partially within the liquid, which is prevented from penetrating the interior of the coil. An alternating electrical current applied to the coil produces a magnetic field about the coil. The current has a frequency and an amplitude such that the magnetic field has an effect on the liquid changing a property of the liquid at a distance of at least 5 meters from the transducer, wherein the property is gas exchange rate, surface tension, viscosity, freezing point, or partial vapor pressure. A system may include two transducers, wherein the electrical currents are offset in phase or frequency for controlling the effect.
