Patents by Inventor Jacob Tallman

Jacob Tallman 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).

  • Low-cost, no-fragment explosive access tool
    Patent number: 6865990
    Abstract: The invention comprises a device that uses a flexible material, preferably in a mostly square shape, having substantially orthogonal grooves scored into one side. An explosive charge, usually in the form of a sheet of explosives, is cut to fit the side opposite the grooves, in substantially the same shape as the grooves, without extending beyond the periphery of the flexible material. An initiating means is connected to the explosive charge so that upon initiation, the grooves focus the explosive charge so that a plurality of petals cantilevered are formed in the target material, substantially between the ends of the grooves, to define a fragment-free opening in the target material.
    Type: Grant
    Filed: January 9, 2003
    Date of Patent: March 15, 2005
    Assignee: The United States of America as represented by the Secretary of the Navy

  • Low cost, high-strength robotic arm
    Patent number: 6431019
    Abstract: The present invention is a robotic arm with a plurality of telescoping tubes coupled rotatably to a plurality of rings through apertures in the rings. A plurality of tendons pass through the telescoping tubes. Tension is applied to the plurality of tendons to move the telescoping tubes. A controller is employed to direct the amount of tension applied whereby the robotic arm moves as directed.
