  • Patent number: 10217618
    Abstract: This disclosure describes systems, methods, and apparatuses for extinguishing electrical arcs in a plasma processing chamber. Once an arc is detected, the steady state voltage provided to the plasma processing chamber can be reduced, and the current being provided to the chamber decays below a steady state value as the arc is extinguished. When the current falls to or below a current threshold, the voltage can be ramped back up bringing the voltage and current back to steady state values. This technique enables power to return to a steady state level faster than traditional arc mitigation techniques.

  • Patent number: 10197606
    Abstract: A system and method for analyzing steady-state powerflow in DC electrical networks in the presence of constant power loads and other nonlinear devices whose I-V characteristics can be modeled using algebraic functions. The networks include high power utility-size grids and microgrids, as well as vehicular, aircraft, and spacecraft power management and distribution systems. The method draws on the mathematical framework of the Holomorphic Embedded Loadflow Method (HELM), which has previously been applied in utility AC networks. The adaptation to DC systems depends on the choice of a proper embedding and a corresponding reflection condition on the embedded voltages. Additionally, the method is extended to nonlinear devices other than constant-power loads, such as photovoltaic panel sources, which are of interest for the power systems aboard spacecraft and other electric vehicles.

    Abstract: A method for detecting a fault in an energy supply network. State values are determined for a plurality of measuring points. The state values, which specify an electrical state of the energy supply network at the respective measuring point, are transmitted to a control center. The state values are used by an evaluation device for detecting a fault in the energy supply network. In order to detect errors in energy supply networks with low short-circuit currents with high reliability and selectivity, the evaluation device performs a state estimation, using a model description of the supply network suitable for describing possible electrical states of the energy supply network on the basis of state variables. The estimation examines whether an electrical state at least approximately matches the respective state values, can be described by the model description. If such a state is lacking, the evaluation device generates an fault detection signal.

  • Patent number: 9450409
    Abstract: Converter stations have real and reactive power set points initially determined as part of a main loadflow analysis routinely performed on the AC power system connected to the converter stations. Viable real and/or reactive power set points for the converter stations can be identified by calculating real and/or reactive power set point candidates for the converter stations before the main loadflow analysis is performed again on the AC power system. The power set point candidates are calculated based on information determined as part of a previous iteration of the main loadflow analysis on the AC power system. The power set point candidates which violate an operating constraint imposed on the AC power system are identified, and a region of valid power set points is defined for the converter stations that excludes the power set point candidates which violate an operating constraint imposed on the AC power system.

  • Patent number: 9428805
    Abstract: A technique is provided for forming a nanodevice for sequencing. A bottom metal contact is disposed at a location in an insulator that is on a substrate. A nonconducting material is disposed on top of the bottom metal contact and the insulator. A carbon nanotube is disposed on top of the nonconducting material. Top metal contacts are disposed on top of the carbon nanotube at the location of the bottom metal contact, where the top metal contacts are formed at opposing ends of the carbon nanotube at the location. The carbon nanotube is suspended over the bottom metal contact at the location, by etching away the nonconducting material under the carbon nanotube to expose the bottom metal contact as a bottom of a trench, while leaving the nonconducting material immediately under the top metal contacts as walls of the trench.

  • Patent number: 9368416
    Abstract: A binning process uses curve fitting to create and assign one or more bins based on testing data of operating voltage versus leakage current for test integrated circuits. Each bin is created by assigning an initial operating voltage to the bin and fitting a curve to the testing data population. An equation is generated describing the fitted curve. Integrated circuits are binned by measuring the leakage current at a selected operating voltage and testing the integrated circuit at one or more operating voltages determined based on the fitted curves. The integrated circuits are assigned a maximum operating voltage that corresponds to the lowest tested operating voltage at which the integrated circuit passes the test.

  • Patent number: 9279700
    Abstract: A method for processing daily consumption, demand and time of use meter reads for electric, gas, water and other metered entities. The meter reads are collected by any of the well known Automated Meter Reading (AMR) technologies and loaded into a meter data warehouse. At a minimum daily meter reading, reads that are tagged as Good, Stale, Partial, Incomplete and Missing are required for properly identifying usage patterns, applying rules for error patterns and estimating the reads which will provide quality meter reads to the utilities thereby identifying meter problems before they become billing problems. The overall process involves loading the daily meter reads into a database, comparing each meter read against its previous day's read and applying a set of rules that help in validating, editing and estimating (VEE) of this data. The VEE rules that are applied can be broadly classified into five (5) categories.

  • Patent number: 9257833
    Abstract: Disclosed are adaptive communication assisted protection and control. Local intelligent electronic devices (IEDs) associated with local switching devices and having unique IDs may transmit switch status and unique IDs to an area IED. The area IED may calculate topology using switch status, and provide control information to local IEDs using the topology. The area IED may communicate the unique ID of the local IED calculated to be immediately upstream of each local IED and, upon detection of a fault, the local IEDs may send blocking signals that include the received unique ID of the IED immediately upstream therefrom. The area IED may communicate control commands that include the unique IDs and control commands for the local IEDs to take the control action. Upon matching of the unique ID in the control command with its own unique ID, the local IEDs may take the control action and transmit remaining actions.

  • Patent number: 9255835
    Abstract: A gas turbine combustor vibration sensing system includes a non-contact reflective optical vibration sensor adapted for reflecting photons off of a component within the combustor with a photon source and receiving reflected photons with a photon detector. Exemplary combustor internal components include the combustor basket or transition. A vibration analyzer is coupled to the vibration sensor, for correlating photons received by the detector with vibration characteristics of the component. Vibration characteristics in turn can be correlated with combustion characteristics, including by way of example flame front position and flameout conditions. Vibration characteristic information may be used as an operational parameter by a turbine monitoring system to modify operation of a gas turbine.
