Marvin Kent Richards 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).

  • Resettable seat with energy absorber
    Patent number: 8146988
    Abstract: A vehicle seat that strokes during an energy absorption process is able to reset. The seat can therefore stroke again, in the same stroking volume, for example during a secondary ground impact after a mine blast. An energy absorber associated with the seat is operative to absorb energy once during the first stroke and is also operative to absorb energy a second time when the seat strokes a second time.
    Type: Grant

    Date of Patent: April 3, 2012
    Assignee: BAE Systems Aerospace & Defense Group Inc.

  • Method and system for determining cracks and broken components in armor
    Patent number: 7180302
    Abstract: A ceramic armor system with built-in conductive circuit attached to a ceramic component. The conductive circuit can be accessed by a user at contacts provided in the system. The circuit is arranged so that damage such as cracks that occurs within the ceramic component can propagate into the conductive material forming the circuit and thereby cause a rupture in the conductive circuit. An electrical probe such as an ohmmeter is used to measure the conductive circuit resistance that is then checked against an expected value. The results are used to determine if the ceramic armor component is in operable condition.
