Byrna Technologies has filed a patent for a system that includes a practice dart for a conducted electrical weapon (CEW). The practice dart is designed to be similar in weight and flight to a conventional electrode used in the field, but it does not pierce target clothing or tissue or deliver a high voltage current. The practice dart includes a body, a cap, and an overlay that allows it to be coupled to a target upon impact.

A recently filed patent (Publication Number: US20230296360A1) describes a practice dart for a conducted electrical weapon (CEW). The practice dart includes a body, a cap mechanically coupled to the body, and an overlay coupled to the exterior of the cap. The overlay is designed to attach the practice dart to a target upon impact.

The overlay of the practice dart includes a nose coupled to the tip of the cap and a plurality of blades that are flexibly coupled to the nose. These blades cover the sides of the cap when folded over it. The overlay can be made of a hook portion or a loop portion of a hook-and-loop fastener.

The cap of the practice dart has a passage, and the dart also includes a spear with barbs that can be inserted into the passage. The interior surface of the passage mechanically interferes with the barbs, securely coupling the cap to the body.

Additionally, the practice dart may have a filament that deploys behind the dart when it moves towards the target. This filament helps to further secure the practice dart to the deployment unit.

The patent also describes a deployment unit that includes a propellant and the practice dart. When the propellant is activated, it launches the practice dart from the deployment unit. The overlay of the practice dart is designed to securely attach to a target wearing a second material that cooperates with the first material of the overlay.

The deployment unit may also include a filament stored in the body of the practice dart, which deploys behind the dart when it moves towards the target. This filament mechanically couples the practice dart to the deployment unit.

The overlay of the deployment unit can be wrapped over the cap and may include a nose and flexibly coupled blades. It can also cover a portion of the sides of the cap.

The cap of the deployment unit has a passage, and the interior of the cap may have protruding lips along the wall. The cap is mechanically coupled to the body of the deployment unit through the interference of the interior surface with the base of a spear.

Overall, this patent describes a practice dart and a deployment unit that provide secure attachment to a target and can be used for training or practice purposes with conducted electrical weapons.
