Patents by Inventor Maximilian Zellner

Maximilian Zellner 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).

  • Sensor array for a capacitance measuring fingerprint sensor, and method for producing such a sensor array
    Patent number: 6481294
    Abstract: A base layer, which is preferably flexible, has first conductor tracks, a first insulation layer, fine structures with first electrodes, second conductor tracks and second electrodes, and finally a second insulation layer applied to it in succession. The first electrodes are connected, via plated-through holes, to associated first conductor tracks. Changes, caused by lines in the skin of a finger pad, in the stray capacitance between adjacent first and second electrodes are evaluated for recording fingerprints.
    Type: Grant
