Nicolaas W. Van Vanno 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 and token reader and associated methods
    Patent number: 6069970
    Abstract: A fingerprint and token sensor system includes an array of fingerprint sensing elements for generating signals related to a fingerprint based upon a finger being positioned adjacent the sensing elements, and a token for also causing the sensing elements to generate signals related to a token message based upon the token being positioned adjacent the sensing elements. Accordingly, the single sensor may be used for both fingerprints and for reading data from a token for range of useful purposes. Each fingerprint sensing element may preferably include an electric field sensing electrode, and a shield associated with a respective electric field sensing electrode. A drive circuit may be connected to the array of electric field sensing electrodes for driving same. The sensor is preferably in the form of an integrated circuit and includes a substrate adjacent the array of fingerprint sensing elements.
