Patents by Inventor Falke Hennig

Falke Hennig 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).

  • Hall effect modulation of resistor values
    Patent number: 5763928
    Abstract: A semiconductor structure is disclosed in which two regions of semiconductor material positioned adjacent to each other have different electron mobilities. By application of a magnetic field to the device, a Hall voltage is created across the boundary region between the regions of semiconductor material to modify their resistance. By detecting the change in resistance, the device can function as a memory cell, a programmable logic device, a head for hard disk drives, a measurement tool for measuring magnetic fields, or other apparatus.
    Type: Grant
