  • Patent number: 10176153
    Abstract: Systems and methods are provided for determining customized markup content to deter malicious attackers and/or to decrease electronic submissions from robots. In some embodiments, markup content may be randomized with unique identifiers, reordering of markup elements, and/or insertion of hidden markup elements. The modifications to markup content may have no impact on human usability of the markup content. However, the customized markup content may render the content unusable by a programmed, automated attacker that cannot parse and/or recognize the content. Thus, automated attackers are deterred from using markup content, while human users remain unaffected.

  • Patent number: 9340842
    Abstract: A reactor system, for electroporation includes a reactor chamber having a length and a width, whereby the reactor chamber contains a central section along its length. A first pulse generator to which two electrodes (A1) and (A2) are connected are located in the reactor chamber in the central section of the reactor chamber such that they are, when measured in the length direction of the reactor chamber, at least a distance equalling half the width of the reactor chamber apart. A second pulse generator to which two electrodes (B1) and (B2) are connected are located in the reactor chamber in the central section of the reactor chamber such that they are, when measured in the length direction of the reactor chamber, at least a distance equalling half the width of the reactor chamber apart.

  • Patent number: 7170198
    Abstract: In trigger/firing arrangement in a Marx generator comprising n stage capacitors—n being a natural number greater than 1-, the same amount of spark gaps and 2(n?1) charging branches, with the spark gaps operating in a self-breakdown mode, the trigger-/firing arrangement comprises at least a pulse transformer connected to an pulse generator in at least one of the charging branches of the Marx-generator, which with the associated stage capacitor bridges a spark gap—except for the output end spark gap—a pulse transformer is disposed, whose output winding operates during charging as a charging winding and whose input winding is connected to the pulse generator in such a way that the voltage pulse generated with this pulse transformer during triggering of the pulse generator is added to the charge voltage of the associated stage capacitor and, with a corresponding polarity, generates an over-voltage sufficient for initiating self-breakdown at this spark gap.
