20090218820 | Power Converter Arrangement and Method - A power converter arrangement for connecting an induction generator to an electric power network comprises a first path provided for transferring electric power from the induction generator to the electric power network during a first operation condition, and a second path provided for transferring electric power from the induction generator to the electric power network during a second operation condition, where the first path includes an AC-AC converter and the second path includes a switch. A capacitor arrangement is interconnected between the induction generator and the first and second paths and a first AC reactor device is interconnected between the capacitor arrangement and the first and second paths, where the capacitor arrangement is provided for compensating for a magnetization current of the induction generator. | 09-03-2009 |
20100292852 | Wind mill power flow control with dump load and power converter - A wind mill apparatus for generating electric power to a grid point of an electric network. The apparatus includes a wind rotor, an electric generator operatively connected to the wind rotor, and an electric multiphase ac link operatively connecting the generator to the grid point. The ac link includes a first current path including a switchgear, a second current path including a dc link including a first converter operatively connected to the generator, a second converter operatively connected to the grid point, and a capacitor operatively connected between the conductors of the dc link. The ac link further includes a connectable multiphase dump load for blocking during a fault condition on the network the reactive power flow in the ac link, yet providing a reduced transfer of active power. | 11-18-2010 |

20140092379 | METHOD AND DEVICE FOR MEASURING GAS COMPONENT CONCENTRATION INSIDE A GLASS UNIT - A non-invasive method for determining a concentration of a gas component in a gas mixture contained in a spacing of a glass unit having at least two glass sheets spaced apart from each other and forming the spacing. One or more light beams is applied at an angle to the surface of the glass unit, wherein the wavelength of the emitted light beam is varied around or over the at least one absorption line of the interest gas component. The light beams transmitted through or reflected from at least one surface or interface locating at the opposite side of the spacing are collected by a detector and non-linear variations in the intensity of the transmitted or reflected light beams over an absorption line of the interest gas is then component determined. The concentration of the gas component to be measured is determined based on the non-linear variations in the intensity. | 04-03-2014 |

20130201538 | CHROMOPHORE BASED NANOCIRCUITS - Certain embodiments relate to systems and methods providing wires, circuits, or circuit elements comprised of one or more chromophores. The chromophores can be “tuned” to the critical edge between quantum order and quantum chaos providing long coherence times combined with quantum delocalization resulting in coherent transport of excitons. Such tuned chromophore systems provide coherent transport at room temperature. | 08-08-2013 |

20110151909 | TAKING CONTROL OF SUBSCRIBER TERMINAL - Taking control of a subscriber terminal is disclosed. An apparatus comprises a processor configured to cause the apparatus: to control a stand-alone base station so that an emulated cell of a cellular radio system is formed by transmitting a control channel with information of a real cell and with such transmission power that a subscriber terminal having an ongoing connection with a serving cell base station is caused to measure reception of the stand-alone base station as being better than reception of the serving cell base station; and to control the stand-alone base station to perform cell reselection with the subscriber terminal so that the ongoing radio connection with the serving cell base station is transferred to continue with the stand-alone base station. | 06-23-2011 |
