  • Publication number: 20150380150
    Abstract: An electrical transformer component includes a central limb having a first and a second end section and a central section, which is arranged between the first and second end sections. The component also includes an outer limb having a holding device for holding the central limb on the outer limb. At least one of the first and second end sections of the central limb is held on the holding device of the outer limb. At least two wires are wound directly onto part of the surface of the central section of the central limb.

  • Publication number: 20120054348
    Abstract: The method provided is for the initiation of a computer session which is shared by two computers that are connected via internet behind NAT routers so that there is no additional relay server necessary. In contrast to conventional methods which can only connect two computers behind NAT routers via a relay server, there is no need to charge users for the incurring additional traffic. The invention regards a method for the initiation of a computer session which is shared by two computers with the following steps: Manual or automatic start on two computers through a communication software that can exchange arbitrary data via a mutually used rendezvous server. Discovery of the local IP address and of a free port and discovery of the global IP address and port on each side. Transmission of the discovered data to the respective peer via the rendezvous server. Hole punching into the respective opposite NAT. Start of a packet-oriented bidirectional transmission protocol with automatic repeat request.

  • Patent number: 7923986
    Abstract: A device for measuring a current flowing in an electrical conductor. The device comprises a magnetic circuit coupled to an electrical conductor. The magnetic circuit has an air gap and a magnetic field sensitive component disposed in the air gap to measure a magnetic field generated by the electrical conductor. A control core has a control winding configured to control an effective length of the air gap when the control winding is energized. A magnetic shield at least partially encloses the magnetic circuit, the magnetic field sensitive component and the control core.

  • Patent number: 7541799
    Abstract: A device for measuring a current flowing in an electrical conductor having a sensor disposed in the region of the electrical conductor for measuring the magnetic field surrounding the electrical conductor. The sensor includes a magnetic circuit having a first and a second section. A magnetizing device for the saturation of the second section and an evaluation device for calculating the current flowing through the electrical conductor in dependence on measured values B(P0), B(P1), B(P2), B(P4), B(P4+), B(P4?) of the magnetic field surrounding the electrical conductor and in dependence on the applicable magnetization of the second section is also provided. A method for operating the device is also disclosed.
