  • Dielectric barrier discharge lamp with starting aid
    Patent number: 6924599
    Abstract: In order to improve the starting of a dielectric barrier discharge lamp it is proposed to provide elements for igniting an auxiliary discharge inside the exhaust tube (5) of the lamp.
    Type: Grant
    Filed: December 2, 2002
    Date of Patent: August 2, 2005
    Assignee: Patent-Treuhaud-Gesellschaft für elektrische Glühlampen mbH
    Inventors: Gerhard Döll, Wolfgang Kumpf, Joseph-A. Olsen
  • Dielectric barrier discharge lamp having an ignition means
    Patent number: 6777878
    Abstract: A dielectric barrier discharge lamp has elongated electrodes (3) that are arranged on the inside of the wall of the discharge vessel (2) and are covered by a dielectric layer (4). Arranged on the outside of the wall of the discharge vessel (2) is an electrically conductive means (8) that is limited with reference to the longitudinal axis to a subregion (B) of the discharge vessel wall, for example a metal ring. The startability of the dielectric barrier discharge lamp when first being started or after long operational pauses is improved thereby.

  • Routing control information via a bus selectively controls whether data should be routed through a switch or a bus according to number of destination processors
    Patent number: 5467452
    Abstract: The invention concerns the transfer of data information in a multiprocessor computer system. If data information has to be transferred between two processor units then the associated control information is made available on a connection bus and the data information is transferred afterwards via a switch unit from the first to the second processor unit. If however data information is to be transferred from a sending processor unit to all other processor units (broadcast transfer) then not only is control information transferred via the connection bus but subsequent data information too; a transfer of data information via the switch unit does not occur in this case. In this manner it is possible to reduce the outlay for the switch unit in terms of circuitry and programming.
