The present invention describes an air-burst projectile (100) and a system (200) for deploying the airburst projectile to counter an unmanned aerial vehicle (UAV) 10. Each airburst projectile includes one or more spinners (140, 140a-140d); each spinner has a sleeve or a tube (146), a number of radial partition plates (148, 148a-148d) extending from the sleeve/tube and an annular rear plate (144) connected to the sleeve. Adjacent partition plates thus form a compartment (150). Disposed in each compartment is a streamer or streamers (170,170a,170b), which are formed in a coiled-up state. When the airburst projectile is deployed into a flight path of a target UAV, the spinners (140, 140a-140d) are ejected and the streamers (170,170a,170b) are dispersed in the flight path to create a streamer cloud, so that a streamer may entangle with propellers of the UAV and bring down the UAV, or as a warning or fence marking shot.

The control system based on multi-unmanned aerial vehicle (UAV) cooperative strategic confrontation includes a management module, a UAV formation module, a situation assessment module, a decision-making module, and a cooperative mission assigning module of both sides in a confrontation. The management module is configured to store state information acquired by the UAV formation module. The UAV formation module is configured to acquire state information of UAVs and execute a control instruction. The situation assessment module is configured to acquire situation assessment information according to the state information. The decision-making module is configured to acquire a countermeasure based on the situation assessment information. The cooperative mission assigning module is configured to generate control instructions for the UAVs based on the countermeasure and in combination with a confrontation target and an optimal situation assessment value.

The present invention discloses a personal protection device for multiple less-lethal ammunition options. The device is comprised of a lightweight carbon-composite forearm sleeve assembly having one or more externally mounted light-weight multi-layer composite barrels of various calibers for dispensing less-lethal ammunition at controlled muzzle velocities. In addition, Picatinny Rail attachment points are provided for mounting external tactical gear. The invention thus provides the user with multiple selectable less-lethal ammunition options in a single device while protecting the operating arm. Internally, the gauntlet contains a pistol grip with an electronic control system for selecting and firing individual less-lethal ammunition.

Methods, devices, and systems may protect a target from undesirable electromagnetic radiation by detecting electromagnetic radiation (including coherent radiation such as laser beams) aimed at a target from a source; calculating a first release position to disrupt the electromagnetic radiation thereby protecting the target; launching a projectile that may include a disruptive medium or a disruptive-medium precursor; directing the projectile to the first release position; and releasing the disruptive medium from the projectile at the first release position, such that the releasing of the disruptive medium forms a cloud of the disruptive medium.

A method of operating a security system with deterrent capability is implemented through security cameras that are articulated and non-articulated, entry doors, and a control unit. The control unit is communicatively coupled with the security cameras and the entry doors as the control unit is supervised by a trained operator. The security cameras continuously send audio and video data to the control unit so that a threatening target can be identified before he or she can do any destruction. When the threatening target is identified, the entry doors are locked and electrified through the control unit in order to provide an initial defense system for the threatening target. Additional deterrence can be implemented at the threatening target through a less-lethal deterrence unit and non-lethal deterrence units of the articulated security cameras while the non-articulated security cameras provide surveillance of the threatening target to the control unit.

A diversionary device trigger mechanism is provided that can be repeatedly used, and. which allows a primer or blank to be discharged in two different ways. The device includes a main body with a number of other components secured to the main body about an upper chamber and a lower chamber. A firing pin, a ball bearing, an anvil, a top retaining cap, and a plunger are secured about the upper chamber. A blank carrier, a primer or blank, and a carrier receiver are secured about the lower chamber. In the first way, the ball bearing can be displaced relative to the main body, such as by throwing the device towards a surface. In the second way, the plunger can be pushed down relative to the main body. If either of these occur, the firing pin to be moved downwardly to pierce and set off the primer or blank.

The invention provides conspicuity devices and methods. A first embodiment includes a glove with at least one elongate lighting device adapted and configured to admit light having an advantageous spectral energy distribution. Additional articles of clothing are provided herein for enhanced conspicuity, such as for emergency workers and athletes.

A projectile deployment system includes an entangling projectile including a pair of pellets and a tether connecting the pellets. A projectile casing includes a pair of sockets, each socket sized to carry one of the pair of pellets and a selectively activatable pressure source, carried by the projectile casing. The pressure source is capable of expelling the entangling projectile from the projectile casing toward a subject. A launcher carries an activator operable to activate the pressure source to expel the entangling projectile from the projectile casing toward the subject. The projectile casing is removably engageable with the launcher to allow removal of the projectile casing from the launcher after expulsion of the entangling projectile from the projectile casing.

Implementations of conductive energy weapons (CEWs) may include a shock generating circuit configured to couple to a power source, two electrodes operatively coupled to the shock generating circuit, and a safety circuit operatively coupled to the shock generating circuit. The shock generating circuit may be configured to generate a first pulse train and deliver the first pulse train to a target, and may be configured to generate at least a second pulse train and deliver the at least second pulse train to a target. The safety circuit may be configured to prevent the CEW from applying pulse trains to the target after a predetermined number of pulse trains. The first pulse train may include two or more pulses having waveforms substantially identical with each other, each of the waveforms of the two or more pulses having both a positive voltage segment and a negative voltage segment.
