摘要:
An electric discharge weapon includes a high voltage circuit, a control circuit, and a light source. The high voltage circuit includes a spark gap having a breakdown voltage affected by light. A magnitude of an electric discharge of the weapon is related to the breakdown voltage of the spark gap. Under control of the control circuit, the light source emits light to illuminate the spark gap prior to conduction so that the magnitude of the electric discharge is within a desired range.

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. For example, a projectile with closely spaced electrodes may stimulate a burning sensation to attract the target to impale the target's hand on a rear facing electrode of the projectile. Use of the rear facing electrode and one or more of the closely spaced electrodes may provide a more effective stimulus circuit through tissue of the target.

An apparatus for immobilizing a target includes electrodes deployed after contact is made between the apparatus and the target. Spacing of deployed electrodes may be more accurate and/or more repeatable for more effective delivery of an immobilizing stimulus signal.

An apparatus, according to various aspects of the present invention, produces contractions in skeletal muscles of a target to impede locomotion by the target. The apparatus is used with a provided deployment unit that deploys an electrode away from the apparatus. The electrode conducts a current through the target. The apparatus includes a terminal; a producing sub-system for producing an electric arc to warn the target without conducting a current through the target; a conducting sub-system for conducting the current in series through the terminal and through the target; an initiating sub-system for initiating deployment of the electrode; and an operator interface. The operator interface facilitates selecting one or more cartridges of a set of cartridges to provide a stimulus signal to a target and/or display an arc.

An electronic weapon with an installed deployment unit, from which at least one wire-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, piercing material or tissue at the target, lodging in material or tissue of the target, focusing an electric field prior to ionization or while conducting a stimulus current, forming an ionized path for a stimulus current across one or more gaps, and spreading 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, spear, and filament, spreading may be accomplished by an end portion of the filament that extends forward of the body and activates the spear by ionization of air or by conduction through target tissue.

A method performed by a weapon, includes interacting with a user of the weapon to receive a first code; determining whether the first code is consistent with a second code in a memory of the weapon to produce a result of determining; testing whether the weapon is in a zone; performing an operation of the weapon in accordance with the result and the weapon being in the zone. Interacting may include monitoring a switch that is operated by the user; and receiving may include determining the first code in accordance with a time between successive operations of the switch. The method may further include disabling performance of the operation in accordance with the weapon being not in the zone. And, after disabling, requiring a repeat performance of interacting and determining whether the first code is consistent with the second code before enabling performing a further operation of the weapon. An assembly for upgrading an electronic control device, the assembly includes an enclosure, an electrical connector, a battery, and a transceiver. The transceiver supplies to the electronic control device a current that conveys a result of testing whether the assembly is in a zone. A device detects that an electronic control device has been used. The device includes a radio receiver and a circuit. The electronic control device generates a radio signal when used. The circuit detects a plurality of properties of the received radio signal and outputs a signal in response to detecting.

A cartridge for a system that uses a stimulus signal for immobilizing a human or animal target includes a propellant and a projectile propelled away from about the cartridge by the propellant. The projectile includes a power supply, a waveform generator, and several electrodes. The waveform generator is powered by the power supply. The waveform generator includes a processor. The electrodes complete a stimulus delivery circuit to conduct a current through the target. The waveform generator generates the current to include a first series of pulses and a second series of pulses. The second series begins after the first series is completed. The first series has a first pulse repetition rate determined by the processor. Each pulse of the first series has a first pulse width of from about 10 to about 1000 microseconds. Each pulse of the first series delivers through the target a first charge per pulse of from about 50 to about 500 microcoulombs. The second series has a second pulse repetition rate determined by the processor to be less than the first pulse repetition rate. Each pulse of the second series delivers through the target a charge greater than a minimum charge per pulse. A product of the second pulse repetition rate and the minimum charge per pulse is greater than 250.

A deployment unit for use with an electronic weapon includes a body, an electrode, an electrical interface and tether wire, and a cover. The body has a cavity with an opening. The electrode is stored in the cavity. The electrical interface and tether wire conduct a current from the electronic weapon through the electrode. The cover is coupled to the body over the opening. Activation of a provided propellant, in any order (a) provides a force that pushes the cover away from the body to open the cavity; and (b) deploys the electrode from the cavity through the opening toward a provided target for conducting the current through the target that interferes with locomotion by the target. Prior to pushing the cover away from the body, no portion of the electrode contacts the cover.

An apparatus produces contractions in skeletal muscles of a target to impede locomotion by an animal or human target. The apparatus is used with at least one electrode for conducting a current through the target. The apparatus may be implemented as an electronic disabling device. The apparatus includes two circuits. The first circuit includes a transformer and a first capacitor. The second circuit includes a second capacitor and a secondary winding of the transformer. The second circuit is a series circuit with the electrode. In operation with the electrode, the transformer impresses a voltage on the electrode of greater magnitude than the first voltage, and the current is responsive to discharge of the first capacitor and discharge of the second capacitor.
