Patents by Inventor Carl A. Feickert

Carl A. Feickert 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: 10256698
    Abstract: The present invention is a fluid power generator with elastic tension gradient strips that move in a serpentine fashion to generate power from fluid flow. Each strip has a tension gradient that decreases going back. This allows steady serpentine movement of the strip to move a coil generator across multiple magnets to generate power. Tensioning tubes keep the strips under tension and attach the strips to a strip support that also supports a magnet holder. The magnet holder keeps the magnets in position within the coil generators so that any serpentine movement of the strip can generate power.
    Type: Grant

  • Patent number: 5528142
    Abstract: A method for quantifying the permeability or conductivity of a conducting material, comprises the steps of providing a circuit including an inductor with a coil and a capacitor connected in parallel to the inductor, the coil having an interior space adapted to enclose the sample material therein; inserting the sample material into the interior space of the coil to completely enclose the sample material therein; resonating the circuit with the capacitor with capacitance C' with the inserted sample material at a resonant frequency f.sub.0 and measuring the resulting impedance, Z' of the circuit; measuring the impedance of the loaded circuit at various frequencies above and below the resonant frequency f.sub.0, and plotting a first bell-shaped curve from the measured impedances against frequencies; resonating the circuit with the capacitor with capacitance C' at a resonant frequency f.sub.x with the sample material removed from the coil and measuring the resulting impedance, Z.sub.
