Albert Scheucher 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).

  • Fingerprint sensor with potential modulation of the ESD protective grating
    Patent number: 7027625
    Abstract: The invention relates to fingerprint sensors. A fingerprint sensor has a plurality of sensor electrodes below a surface intended for contacting the underside of a finger. At least one protective electrode is mounted on the surface. The sensor electrodes can have a first AC voltage at a prescribed frequency applied to them. The protective electrode can have a second AC voltage, which is essentially at the prescribed frequency, applied to it.
    Type: Grant
