Patents by Inventor Douglas J. Landers

Douglas J. Landers 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).

  • Publication number: 20140153153
    Abstract: An electronic weapon with an installed deployment unit, from which at least one tethered electrode is launched, provides a stimulus current through a target to inhibit locomotion by the target. The wire tether, also called a filament, conducts the stimulus current. The one or more electrodes, according to various aspects of the present invention, perform one or more of the following functions in any combination: binding the filament to the electrode, deploying the filament from the deployment unit, coupling the electrode to the target, and distributing a current density with respect to a region of target tissue and/or a volume of target tissue. For an electrode that includes a body and a spear, the spear may be implemented with conductive rings or with materials that include integrated conductive and insulative substances (e.g., conductive fibers in insulative composite material). Relatively high electric field flux density at a tip of the spear may be reduced or avoided by practice of the invention.
