Patents by Inventor Nico Stechemesser

Nico Stechemesser 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).

  • Patent number: 9651601
    Abstract: The invention relates to circuit arrangements for cable checking, cable testing, cable diagnosis and/or cable fault localization with a voltage source having a first voltage multiplier for a positive voltage and a second voltage multiplier for a negative voltage current sources that are connected to one another in combination with the voltage multipliers to generate a test voltage over the load impedance of the cable to charge and discharge the load capacitance of the cable and a control device that is interconnected with the voltage source and the current sources and devices with a circuit arrangement of that type. The circuit arrangements distinguish themselves, in particular, by the fact that arbitrary voltage curves of different amplitudes can be generated through the cable as the impedance acting as the test specimen.

  • Patent number: 8970223
    Abstract: An apparatus for testing a cable or other capacitive load object with a VLF alternating cosine square, rectangular or trapezoidal test voltage, includes one or two DC voltage sources and a switching arrangement controlled by a measuring and control unit, to produce the test voltage with alternating switched polarity. The apparatus further includes a choke coil serving as an energy store, which is controlled by a switching element to be activated if the voltage/time slope arising during the switch-over after a respective half-wave of the test voltage falls below a defined threshold value.
