A tool. A firearm, a blade and an ancillary device are disposed within or on the tool. The firearm comprises a barrel through which a bullet passes to exit the firearm, a firing pin moveable to a firing position by operation of a firing pin control, a firing pin lock retaining the firing pin in the firing position when in the locked position, a biasing member for applying a force to the firing pin with the firing pin restrained against the force by the locked position of the firing pin lock. A trigger releases the firing pin lock from the locked position, such that the force causes the firing pin to strike the charge proximate the bullet. The bullet then exits the barrel.

Ballistic shields having a convex configuration including a middle section and forward angled left side and right side wings. The shields may also include at least three manual or electro-mechanical roller units, transparent windows or display devices with cameras or other motions sensors, and spikes, electro-shock devices, or non-lethal incapacitating devices.

An exercise device having a bar with a first handle, a grip exerciser having a second handle connected to the bar via a resistance member proximate the first handle and movable between a first position and a second position by a hand of a user; and an auxiliary device connected to the bar selected from a light assembly, a sound generator, an electrified defensive unit, a pressurized defensive unit, and combinations of the same.

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.

Systems, methods, and articles are disclosed for the behavioral treatment of an individual. One embodiment comprising a wearable housing assembly further comprising a microcontroller, charging jack port, status monitor, selection element, sensor array, and deterring member attached to the user via a connection strap, adjustment belt, frame, prong, and adjustment hole. The user selects the input/output properties of the microcontroller, status monitor, sensor array, and deterring member using the selection element. Upon performing an undesirable emotional outburst, the user is automatically administered a deterrence element, causing the cognizance of, or the inability to engage in, the undesirable behavior. Other embodiments are described and shown.

A deployment unit for use with a handle of a conducted electrical weapon (CEW). The deployment unit includes wire-tethered electrodes for launching toward a human or animal target for providing a current through the target to impede locomotion of the target. The deployment unit includes a barrier that prior to use with the handle protects the deployment unit from electrostatic discharge. Prior to use of the deployment unit, the barrier may further protect the deployment unit from ingress of dirt and/or moisture into the deployment unit. While the deployment unit is inserted into a handle, the barrier shields conductors of the handle and the deployment unit to facilitate delivery of a launch signal from the handle to the deployment unit to launch the wire-tethered electrodes.

A safety guard for an ammunition cartridge (cartridge) of a conductive energy weapon (CEW) includes a body having a first electrical contact on a first side of the body and a second electrical contact on a second side of the body opposite the first side of the body. The first and second electrical contacts are in electrical communication with each other through the body. The first and second electrical contacts are configured to contact a first electrode of the cartridge and a second electrode of the cartridge, respectively, when the body is placed over the cartridge. The safety guard is configured to prevent the cartridge from firing when a firing input, such as a trigger pull, is received by the CEW from a user. In implementations the body incudes at least one clip having a projection configured to be inserted in a corresponding depression of the cartridge of the CEW.

Methods and apparatus for detecting a magnitude of a voltage at a face of a conducted electrical weapon (CEW). The magnitude of the voltage may be used to determine whether a pulse of a stimulus signal was delivered to a target. Structures for detecting the magnitude of the voltage may include structures that provide a stimulus voltage.

The present invention provides an unmanned aerial vehicle with non-lethal neuromuscular incapacitation system comprising a body, a plurality of rotary assemblies secured to the body and configured to provide lift, a control system disposed within the body, and a telescoping stinger assembly mounted on the body. The telescoping stinger assembly comprises an elongated projectile having a barb at a first end thereof, a wire having a first end attached to a second end of the elongated projectile, a high voltage pulse power supply attached to a second end of the wire, and firing mechanism for launching the projectile from the telescoping stinger assembly toward a target. A protective cage may be attached to and surround the body of the UAV. The non-lethal incapacitation mechanism may include a plurality of stinging stickers attached to a periphery of the protective cage, a RF power supply and RF transmitter attached to the body of the unmanned aerial vehicle, or a mechanism affixed to the body of the unmanned aerial vehicle for discharging a liquid or powder substance at a target. Alternatively, a rotary sting arm may be affixed to the body by a rotary brush high-voltage connection; and a sting arm motor mounted proximate to a center of the body may be used to impart rotary motion to the rotary sting arm.
