Effective self defense shouldn't put you nor others in danger the way bullets fired from guns do. By carrying one or more polybags of glass marbles in one's pockets, it is possible to throw such hard enough to injure an attacker by the force of the impact, plus deliver a red-pepper-laced, viscous detergent to their face, when the thin-wall polybag ruptures. The dozens of marbles and the slippery detergent that leak out, make it difficult for the attacker to stand up, thus limiting their ability to harm others.

A baton has a body with a first end and a second end. A handle is connected to and extends from the body between the two ends. A cap is hingedly connected to an end of the handle. A locking mechanism selectively locks the cap to the handle and includes a catch plate that includes a catch, a latch releasably engaged with the catch, and an actuation button. The actuation button is movably engaged with the latch to disengage the latch from the catch. The actuation button is movable along a stop axis and a latch axis different than the stop axis.

A mobile device includes a camera unit, a location unit, a transmitting unit, a self-defense mechanism, and a panic button. The camera unit location unit obtains at least one of image data and audio data, and the location unit obtains location data. The transmitting unit transmits at least one of the image data, the audio data, the location data, and specific information including owner identification information. The panic button is adapted to activate the camera, the location unit, the transmitting unit, and the self-defense mechanism.

A backpack material dispenser that includes a pumpless pressure tank for storing and discharging a material under pressure contained in the pressure tank and a hose and a shut off valve connected to an output opening of the pressure tank for allowing flow of the material from the pressure tank under pressure and through a nozzle communicating with a discharge end of the hose. A discharge valve communicates with the nozzle proximate the hose for allowing controlled discharge of the material from the nozzle. A backpack assembly mounts the pressure tank for being carried by a user. A charging tank contains a gas under pressure to charge the pressure tank to a predetermined pressure, and a releasable connector of the charging tank attaches to a complementary connector of the pressure tank for charging the pressure tank with the gas under pressure to the suitable pressure tank pressure.

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.

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.

An interlocking telescopic rod-type defense spray apparatus includes: a first tube body, a cap and a second tube body. The first tube body has a receiving chamber for placing an irritant gas can. The cap covers the receiving chamber. A rod body portion of the second tube body includes an upper tube, a lower tube, and a telescopic-rod packing device connecting the upper tube and the lower tube. Two sectioned tube pieces and a spring pin component and a push joint component between the two tube pieces are applied to lock and unlock a relative position relationship between the two tube pieces, so that the defense spray apparatus has composite functions of a rod-piece additional function of a locking configuration of relative positions of the two tube pieces and a press-lever spray irritant gas can of an unlocking configuration of the relative positions of the two tube pieces.
