US12643731 - Dispensers for spraying chemical irritants and methods of using

Dispensers for spraying a chemical irritant and methods of using dispensers. Such a dispenser includes a casing having an interior cavity and an access opening to the cavity. The interior cavity receives a cannister with a release valve oriented toward the access opening. An actuator is slidingly disposed in the access opening for actuating the release valve, and a retention mechanism releasably retains the actuator in the access opening. The retention mechanism includes a resilient leg and a radial shoulder extending radially inward from an interior wall of the interior cavity. The radial shoulder captures a foot of the resilient leg so as to inhibit removal of the actuator from the access opening. A wall of the actuator is operable to deflect the resilient leg radially inward to enable the foot to travel over and past the radial shoulder and allow the actuator to be removed through the access opening.

US12571615 - Smart personal safety devices, systems, and methods

Smart personal safety device, system, and method. A personal safety device for dispensing a chemical irritant includes a body for receiving a product cannister, a first actuation mechanism for dispensing product from a product cannister received within the body, and a wireless data communication module coupled to the body for wirelessly transmitting a triggering signal to a remote receiver when the first actuation mechanism is actuated to dispense product from a product cannister received within the body. The wireless data communication module is separable from the body. The wireless data communication module includes a second actuation mechanism configured to actuate the data communication module when the wireless data communication module is separated from the body. The personal safety device can be incorporated into a personal safety system that can send an emergency alert signal to third parties when the chemical irritant is dispensed.

US12535301 - Active protection against beam-riding guided munition

The presently disclosed subject matter includes an active protection system and a method, dedicated for detecting, locating, and incapacitating beam-riding missiles and in that way protecting an asset from being targeted by the missile. According to some examples following receipt of a threat-indication, the active protection system estimates a location of a beam used for directing a threat (e.g., ATGM) to the target and launches an aerial platform that flies in the opposite direction along the beam until it meets and incapacitates the incoming threat.
