Daniel Lenko 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).

  • Electronic primer ignition system
    Patent number: 5515783
    Abstract: Ignition current is conducted by a firing circuit through a firing pin to a rimer mixture retained by its cap within a cartridge case from which the cap is electrically separated by an insulator to effect primer ignition with reduced lock time by activation of a firing switch independently of the firing pin. Voltage for the firing circuit is derived from a battery, maintained in a charged condition by alternate voltage supply sources, and stored at an ignition firing level for a prolonged period of time to accommodate selective activation of the firing switch after the firing pin contacts the primer cap.
    Type: Grant
    Filed: November 15, 1993
    Date of Patent: May 14, 1996
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: Philip W. Hesse, Raymond Goetz, Daniel Lenko
