  • Patent number: 8369059
    Abstract: An exemplary method is disclosed for disturbance current compensation for an electrical system by a disturbance current compensation device, which electrical system has a voltage source and a series circuit which is connected via a conductor in parallel with the voltage source. The series circuit has an inductance and a capacitance, with the inductance being connected in series with the capacitance via a conductor. To compensate for disturbance currents, the conductor for the connection of the voltage source to the series circuit of the inductance with the capacitance, and/or the conductor of the series circuit between the inductance and the capacitance, can be surrounded by a ring (e.g., a portion of the conductor can be substantially surrounded by the ring) which can be magnetized. The ring includes an air gap of the disturbance current compensation device. A compensation voltage can be applied by magnetization of the ring.

  • Publication number: 20080208655
    Abstract: The enterprise database system provides methods, data, and user interfaces for generating approvals and documentation related to forming or acquiring an entity or to initiating a transaction involving an entity. The system also provides the ability to store entity or transaction information in a historical database for retrieval. The system further provides analysis and report generating features, including generating current and historical reports related an entity or transaction, such as general corporate, regulatory and financial reporting documentation. The system also provides methods for modifying entity or transaction information in the historical database. The system further includes various interactive displays and notification tools to implement or facilitate the foregoing methods and systems.
