  • Patent number: 7856929
    Abstract: An electrified projectile, according to various aspects of the present invention, delivers a current through electrodes and through a target. The projectile stows the electrodes with a film and deploys the electrodes in the absence of the film. Deployment is accomplished by a release of torsion. A spur may include two electrodes and a loop. The spur may store the torsion and conduct the current.

  • Patent number: 7849624
    Abstract: A product is sold at retail in an unusable state. Activation of the product does not require any steps be taken by the retail seller. To activate the product, the purchaser uses a phone or personal computer to interact with a registration server for this type of product. Alter the consumer has provided sufficient identifying information, the registration server interacts with a qualification server that determines whether the purchaser meets the qualifications set for this type of product. For a weapon sale, this is typically a criminal background check. If qualified, the registration server receives an indication of qualification from the qualification server. The registration server and product communicate over a network to establish trust, store information in the product, and then activate the product. The product receives information via a network appliance, for example, a phone or personal computer. The receiver may sense sound from a speaker or light from a display of the network appliance.

  • Patent number: 7821766
    Abstract: An apparatus for interfering with locomotion of a target by conducting a current through the target includes according to various aspects of the present invention a transformer, a capacitance, a charge detector, and a processor. The transformer has a secondary winding that is coupled to the target to provide the current. The capacitance is in series with the secondary winding and is charged to a voltage. The charge detector detects a charge provided through the target by the capacitance and the secondary winding. The processor sets the voltage (e.g., for charging for a next pulse) responsive to the charge detected by the charge detector.

  • Patent number: 7800885
    Abstract: A method for immobilization of a human or animal target passes a current through a circuit that includes tissue of the target. The current causes pain compliance or interferes with skeletal muscle control by the target. The method includes in any practical order: (a) generating a first compliance signal of the current, the first compliance signal having a first maximum amplitude; and (b) generating a second compliance signal of the current, the second compliance signal having a second maximum amplitude. The absolute value of the second maximum amplitude is less than the absolute value of the first maximum amplitude. A system that performs such a method may include a processor, a signal generator, and electrodes or terminals for forming the circuit through tissue of the target. Systems, according to various aspects of the present invention, may include stun guns, dart weapons, electronic control devices, electrified projectiles, and mines, to name a few applications.

  • Patent number: 7782592
    Abstract: An electronic disabling device includes first and second electrodes positionable to establish first and second spaced apart contact points on a target having a high impedance air gap existing between at least one of the electrodes and the target. The power supply generates a first high voltage, short duration output across the first and second electrodes during a first time interval to ionize air within the air gap to thereby reduce the high impedance across the air gap to a lower impedance to enable current flow across the air gap at a lower voltage level. The power supply next generates a second lower voltage, longer duration output across the first and second electrodes during a second time interval to maintain the current flow across the first and second electrodes and between the first and second contact points on the target to enable the current flow through the target to cause involuntary muscle contractions to thereby immobilize the target.

  • Patent number: 7673411
    Abstract: A method is performed by an electronic weapon system. The electronic weapon system is aimed in a first direction toward a target. The method includes, deploying an electrode of the system in a second direction different from the first direction, to compensate for drag of a tether wire deployed with the electrode. For example, a tether wire deployed from a tether wire store located adjacent to a cavity from which the electrode is propelled may exert a drag force causing inaccuracies of the propelled electrode. Compensation is accomplished, for example, by virtue of shaping the cavity. Compensation improves accuracy of the electrode striking the target.

  • Patent number: 7602597
    Abstract: Systems and methods for immobilizing a target such as a human or animal with a stimulus signal coupled to the target via numerous electrodes select particular electrodes to use for the stimulus signal. Subsets of electrodes may be tested by applying a test signal and monitoring the energy or charge delivered during a prescribed time. If the delivered energy or charge using a particular subset of electrodes as indicated by monitoring test pulse amplitude suitably compares to a limit, then the particular subset is selected for applying the stimulus signal. A first stimulus signal may be applied to a first subset of electrodes to prompt movement of the target toward an electrode that, when better coupled to the target as a consequence of movement of the target will provide a more effective subset of electrodes for further stimulus.

  • Patent number: 7520081
    Abstract: An improved electric weapon immobilizes a target by conducting a current through an electrode and through the target. The weapon includes a circuit that outputs a pulse pattern having a first pulse, a second pulse of opposite polarity compared to the first pulse, and a period of no output between the first pulse and the second pulse. The period is in a range from 50 microseconds to 1000 microseconds. The electric weapon repeats the output of the pattern at a rate of 19 repetitions per second. A method for immobilizing a target is performed by an electric weapon. The method includes delivering a first pulse in a first polarity, operating a switch to reverse the polarity of delivery; and delivery the second pulse in a second polarity. The method may further include awaiting lapse of a period between delivery of the first pulse and delivery of the second pulse wherein the period is in the range of from 50 microseconds to 1000 microseconds.
