  • 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.

  • Publication number: 20130305949
    Abstract: Methods and apparatus for delivering a dosage of a drug to a target use an electrode that may deliver the drug and/or a current through the target to impede locomotion of the target. Delivery of a dosage may be accomplished by selecting one or more electrodes from a plurality of electrodes to deliver the drug or by metering deliver of the drug from one or more electrodes. Delivery of the current may be accomplished by one or more, preferably two electrodes. The electrodes that deliver the current through the target may also cooperate to deliver the dosage of the drug to the target.

  • Patent number: 8484876
    Abstract: Method and apparatus are disclosed for launching electrified projectiles from a firearm (preferably, a shotgun) by using a specially designed breech bolt which also prohibits firing lethal ammunition. The preferred method comprises: opening a receiver of a shotgun by retracting a breech bolt having a central protrusion on a leading end; inserting a cartridge, having an electrified projectile, into a breech of the firearm; wherein the electrified projectile contains a primer and adjacent pyrotechnic propellant; nesting an end portion of the cartridge within the protrusion of the bolt; propelling the electrified projectile from the firearm by striking a firing pin of the shotgun against the primer, thereby igniting the pyrotechnic propellant, of the nested electrified projectile; and prohibiting, by the central protrusion of the bolt, the firing of lethal ammunition from the firearm.

  • Publication number: 20120170167
    Abstract: A deployment unit for an electronic control device (ECD) used as a weapon provides a current from a signal generator of the ECD through tissue of a human or animal target. The deployment unit includes a housing, an interface, a filament, and an electrode. The interface couples the housing to the signal generator. The filament includes a first end coupled to the interface for receiving the current and comprises a second end. The filament conducts the current for inhibiting voluntary movement by the target. The electrode, stored in the housing prior to deployment, mechanically couples the filament to the target when deployed. The electrode includes an assembly of a first part and a second part that after assembly cooperate to bind the second end of the filament to the electrode.

  • Patent number: 8171850
    Abstract: A weapon conditionally activates a cartridge. The cartridge has a projectile and a first mechanical feature. The weapon includes an activator and a station. The activator includes a second mechanical feature. The station positions the cartridge so that the first feature opposes the second feature. On condition that the first feature does not mechanically interfere with the second feature, the activator activates the cartridge to launch the projectile from the cartridge. On condition that the first feature mechanically interferes with the second feature resulting in an excess head space, the activator is inhibited by the excess head space from activating the cartridge.
