Patents by Inventor Olaf Mann

Olaf Mann has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Apparatus for filtering signals of an antenna arrangement and a sender/receiver arrangement with two or more antennae
    Patent number: 5991606
    Abstract: A pair of filter units directs incoming signals from an antenna and outgoing signals to the antenna. One of the filter units blocks the outgoing signals and passes the incoming signals while the other of the filter units blocks the incoming signals and passes the outgoing signals.
    Type: Grant

  • Coaxial antenna
    Patent number: 5926149
    Abstract: A coaxial antenna includes a vertical half-wave dipole with a lower section in form of a sleeve and an upper section in form of a first conductor bar, with the sleeve being dimensioned so as to resonate at a first frequency or first frequency range. A second conductor bar is operatively connected to the free end of the first conductor bar to define an assembly of first and second conductor bars which is dimensioned so as to resonate at a second frequency or second frequency range.

  • Current supply means for a laser flash lamp
    Patent number: 5585698
    Abstract: Current supply means for a laser flash lamp contain a fast switch and control means which modulate the amplitude of each individual pulse with a presettable modulating frequency and depth of modulation. This permits higher peak envelope powers to be obtained at an unchanged mean power of the individual pulses so that the necessary threshold values can be better exceeded during materials processing. The amplitude modulation of the individual pulses also prevents undesirable shielding plasma from forming above the processing place.
