  • Patent number: 5698815
    Abstract: An electronic projectile (10) for use with a standard cartridge (1). Projectile (10) and cartridge (1) are loaded into standard firearms and fired like a standard bullet. After leaving the barrel of a firearm, plastic sheaths (8L) and (8R) fall away and electrodes (19L) and (19R) extend outward on wires (40L) and (40R). On impact the electrodes penetrate the skin of the target making electrical contact with internal tissue of a target. Within projectile (10) a battery (50) powers internal electronics (30) to charge output capacitors (22) and (24) to high voltage. When the capacitors are fully charged a switch (58) completes the circuit and discharges the capacitors through the target. Switch (58) discharges the capacitors 20 to 100 times per second. These pulses continue for several seconds to incapacitate the target. The polarity of the current is changes once or twice per second to alternate between acidic and basic ions being formed around the electrodes to sterilize the puncture sight.

  • Patent number: 5691501
    Abstract: A nonlethal long-range bullet designed to be fired from a conventional hipowered rifle or pistol spreads apart on impact, thereby delivering a nonlethal blow to the target. Prior to impact, the inventive bullet maintains its aerodynamic shape. The bullet includes a front section in a forward portion of the bullet, the front section having a tail that extends to a rear portion of the bullet; a solid section in the rear portion of the bullet, the solid section including most of the mass of the bullet and being substantially disposed around the tail; at least two longitudinal scribe lines that extend along the front section and the tail; and at least another two longitudinal scribe lines that extends along the solid section and are aligned with the at least two longitudinal scribe lines, wherein depths of the at least two and at least another two longitudinal scribe lines are such that the bullet maintains shape integrity during flight while readily deploying into a flattened shape upon impact.

  • Patent number: 5585595
    Abstract: Shots and hits are simulated with pyrotechnic indicator means e.g. in military maneuvers. For this purpose, devices are used which are designed for accommodating a plurality of pyrotechnic indicator means (15) . Each indicator means (15) can individually be ignited electrically. To this end, an ignition device is provided which has ignition connectors (16) leading to the ignition contacts of each indicator means (15). In known devices of this type making a contact between the indicator means (15) and the ignition connectors (16) requires relative high expenditure of time. Furthermore, faulty connections cannot be excluded. As a result, reloading the device becomes time-consuming and unreliable.The device according to the invention provides that either each ignition connector (16) or each indicator means (15) is provided with at least one annular circumferential contact.

    Abstract: This invention relates to a safety explosion-sound generating type of bullet for a toy gun, and more particularly one having a cavity formed in a plastic body filled with a material which can produce an explosion-sound effect by collision with a hard object and it is covered by a thin layer. When the body is fired and lands against a hard object, the filling material produces a small explosion, like a sound produced by an actual gun. Furthermore, because the small explosion is produced within a very small bullet (for example, a BB), it is impossible to hurt people.
