Abstract: A system for a practice electrode (e.g. dart) for a conducted electrical weapon (“CEW”). An officer issued a CEW is required to practice with the CEW in order to maximize its safe and effective use in a stressful situation. Preferably, training is performed using equipment as similar as possible to the equipment an officer uses in the field. Training with a CEW may include using a CEW to launch darts toward a human target. Training with a CEW against a live target may be improved, at least from the perspective of the target, by using a practice dart that is similar in weight and flight to a conventional electrode, but that does not pierce target clothing or tissue or deliver a high voltage current through the target. A practice dart may be similar to a conventional electrode, but include additional structure (e.g. cap) that prevents piercing. The additional structure and/or a non-conductive filament may be used to reduce a likelihood of or preclude delivery of a current through the target.

Alternatively, the capsule may be coated with a contact adhesive so that it sticks to the bullet wall defining the opening. A peel-off covering atop the strip shields the contact adhesive from contamination.

Abstract: A projectile structured to be discharged from a firearm includes a body having a nose portion and a tail portion separable from one another when the projectile strikes a target. The body further includes an interface disposed intermediate opposite ends of the body of the projectile structured to removably interconnect the nose and tail portions. Separation of the nose and tail portions such as when striking a soft tissue is caused by the tumbling of the projectile and the cooperative structuring of the interface to facilitate separation of the nose and tail portions. The interface is disposed, dimensioned and structured to define the primary area of contact of the projectile body with the rifling or interior surface of the barrel of the firearm. Another embodiment includes one of the nose or tail portions structured to contain a supplemental payload that is carried to the target upon discharge of the firearm.

Abstract: A non-lethal projectile consisting of a solid capsule filled with a flowable payload. The solid capsule comprises a weakened area that ruptures upon impact with a target. The solid capsule also comprises an internal hydrodynamic structure. At the moment of impact, the internal hydrodynamic structure forces the radial movement of the flowable payload, from the center to the periphery, against the weakened area of the solid capsule, facilitating the rupture and reducing the pressure of projectile's point over target's surface.

Abstract: A projectile is provided for delivering a payload from a smoothbore launcher to a target. The projectile includes an aerodynamic stabilizer, an extender along which the stabilizer can longitudinally translate, and a chamber connected to the extender to contain the payload. The chamber can include a plastic bag for containing a liquid that represents the payload, and a plurality of holes that radially extend through its wall. The stabilizer enhances post-launch directional stability of the projectile by longitudinally translating rearward along the extender to shift center of pressure of the projectile aft of center of gravity of the projectile. The bag ruptures upon contact with the target, thereby disbursing the liquid through the holes. The bag can include malodorant or paint. The projectile can be contained within a gunpowder-loaded shotgun shell for launch.

The nose cap 5 is of a readily breakable plastics material or designed to assist retardation.

Abstract: A method for non-lethal crowd and personal protection. The method includes: firing non-lethal bullets towards a person; and deploying portions on the non-lethal bullets prior to impacting the person to decrease its impact pressure on the person.

Abstract: A non-lethal projectile or a projectile for delivery of a substance (optional) has a tubular body casing (1) which surrounds a compartment (2) for containment of the substance. The compartment (2) coaxially supports a hollow tube (5) projecting forward within an ogival nose cap (8). An inflatable membrane (7) is located within the nose cap (8). On target impact the nose is displaced and permits a small amount of substance from compartment (2) to bleed through opening (6) allowing piston (4) to move forward uncovering ports (16). This action allows pressure gas to pass through the ports (16) and ducts to inflate the membrane (7). The piston is also free to move forward to discharge the substance through needle (5). The bag (7) thus expands rapidly and prevents excess penetration whilst spreading the impact energy over a wide area. The construction avoids the need for a charge to be contained within the projectile itself.

Abstract: A specialty bullet is disclosed that is adapted to transmit a tranquilizing fluid upon impact with a target for purposes of immobilizing the intended target without causing great harm to the target or the surrounding area.

Abstract: An animal syringe system for injecting animals with a syringe using a delivery system that allows application at a distance away from the animal. The animal syringe system includes a drug-dispensing syringe inserted into an inner syringe sleeve correspondingly inserted into a two-sized compression spring inserted into an outer sleeve. This assembled drug-dispensing projectile is loaded into a velocity adjustable air rifle. The drug-dispensing projectile is fired at an animal with the syringe needle impaling the animal. A trip device is then triggered releasing tension springs on the plunger of the syringe which injects the drug dose into the animal. As the plunger reaches its endpoint it triggers a two-sized spring inside the outer sleeve which pushes the inner sleeve and syringe away from the animal and the front end of the outer sleeve. As the syringe needle retracts completely into the outer sleeve the drug-dispensing projectile falls harmlessly to the ground.

Abstract: A remote injection device for animals comprises a barrel with a piston slideable within the barrel from an initial retracted position at one end of the barrel forwardly toward the opposed end of the barrel to discharge liquid in an injection action through a needle at the forward end of the barrel. The piston is held in a retracted position by an O-ring on a release member which projects through an O-ring carried on the inside surface of the barrel. The inner diameter of the O-ring on the barrel can be adjusted by axial movement of the pair collars on the inside of the barrel. This adjusts the amount of force necessary to push the release member O-ring through the outer O-ring to release the piston to be moved by spring to the discharge position. The barrel can be mounted either upon an arrow type projectile so the impact forces are sufficient to release the piston upon engaging the animal.
