Dereck B. Clark 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).

  • Methods and apparatus for preventing reverse-engineering of integrated circuits
    Publication number: 20020199111
    Abstract: A structure is configured to inhibit reverse-engineering of an integrated circuit by creating a protective “cocoon” around the IC and associated circuits. The cocoon material is, in one embodiment, designed such that if it is tampered with, one or more electrical device parameters (e.g. capacitance, resistance, etc.) of the cocoon will change, and the IC will detect the changes and act accordingly, e.g., by destroying the valuable encryption keys, programs, or other information that is being protected under or near the cocoon material.

  • Methods and apparatus for interfacing an encryption module with a personal computer
    Patent number: 5517569
    Abstract: An encryption module for encrypting financial and other sensitive data may be conveniently interposed in series between a personal computer and the keyboard associated therewith. An application program designed to run on the PC is configured to prompt the user to enter his PIN or other confidential data into the encryption module; consequently the confidential data need not be transmitted in an unencrypted fashion, and need not reside on the PC hard drive in an unencrypted form.

  • Method of analyzing and predicting both airplane and engine performance characteristics
    Patent number: 5070458
    Abstract: Aircraft/engine performance is determined by the method of the present invention, wherein the performance characteristics are defined by learned performance parameters. The method includes the steps of learning the performance parameters of the aircraft/engine combination, for a given flight, using previously learned performance parameters and current observations. Then, based on the performance parameters learned from the learning step, a prediction is made of the performance of the aircraft/engine combination for subsequent flights.
