  • Publication number: 20230140789
    Abstract: The present disclosure describes providing robust network connectivity by creating a virtual overlay network over a plurality of communication network channels, such that if there is a failover on a first network, a failover overlay tunnel may be used to prevent an interruption in service when the first network drops. An SD-WAN remote may be deployed at an edge location of a network and an SD-WAN base may be installed at a client premises. A first overlay tunnel using a first communication transport may be utilized as a default route and a second overlay tunnel using a second communication transport may be used as a failover route.

  • Patent number: 11367598
    Abstract: A vacuum pumping line plasma source is provided. The plasma source includes a body defining a generally cylindrical interior volume extending along a central longitudinal axis. The body has an input port for coupling to an input pumping line, an output port for coupling to an output pumping line, and an interior surface disposed about the generally cylindrical interior volume. The plasma source also includes a supply electrode disposed adjacent to a return electrode, and a barrier dielectric member, a least a portion of which is positioned between the supply electrode and the return electrode. The plasma source further includes a dielectric barrier discharge structure formed from the supply electrode, the return electrode, and the barrier dielectric member. The dielectric barrier discharge structure is adapted to generate a plasma in the generally cylindrical interior volume.

  • Patent number: 11222770
    Abstract: A microwave system has a solid-state generator which generates microwave energy and includes at least one control input for receiving a control signal to vary electrically a parameter of the microwave energy. A microwave load receives the microwave energy and produces an effect in response to the microwave energy. A microwave conducting element couples the microwave energy to the microwave load. An impedance match adjusting device is coupled to the microwave conducting element to vary at least one of the parameters of the microwave energy. The effect produced in response to the microwave energy is altered by both electrical variation of the parameter of the microwave energy via the control signal and adjustment of the impedance match adjusting device to vary the parameter of the microwave energy.

  • Patent number: 11024489
    Abstract: A method is provided for cleaning a pumping line having a plurality of inline plasma sources coupled thereto. The method includes supplying a cleaning gas to the pumping line from a wafer processing chamber connected to the pumping line. The method also includes generating a localized plasma at one or more of the plurality of inline plasma sources using the cleaning gas flowing in the pumping line. Each localized plasma is adapted to clean at least a portion of the pumping line. The method further includes determining one or more impedances of the localized plasma at the one or more inline plasma sources and monitoring the one or more impendences to detect an endpoint of the cleaning.

  • Patent number: 10910798
    Abstract: An apparatus and method for determining the health of a plasma system by igniting a plasma within a plasma confining volume generate an ignition signal with an ignition circuit and apply the ignition signal between a biased region and a grounded region in the vicinity of the plasma confining volume. A parameter in the ignition circuit is sensed, and the sensed parameter is compared to a first parameter threshold. A condition associated with the plasma confining volume is determined if the sensed parameter differs from the first voltage threshold, and a corrective action can be taken.
