Abstract: A system and method include a swab, configured to collect particles for detection by a particle detection system, that includes integral, machine-readable identification data that identifies the swab and is used by the particle detection system to at least activate one or more functions of the particle detection system associated with an efficacy of the swab for use by the particle detection system.

Abstract: A water spraying assembly includes a spray unit is selectively positioned on a support surface thereby facilitating a user to stand within the spray unit. The spraying unit is fluidly coupled to a fluid source thereby facilitating the spraying unit to spray a fluid onto the user. A spin unit is rotatably coupled to the spray unit and the spin unit is selectively rotated in a first direction. The user repeatedly jumps over the spin unit when the user stands within the spray unit. A remote control is provided and the remote control is in electrical communication with the spin unit such that the remote control selectively turns the spin unit on and off.

Abstract: A dual grip walking and defense baton comprising a shaft, a medial grip located axially along a medial region of the shaft, and an end grip located axially along a region adjacent a first end of the shaft. The shaft can be telescopically extendible from a second end and can be fitted with a defense spray and/or a flashlight mechanism. A contact member can be disposed on the second shaft end for applying force to an assailant's pressure point. A wrist strap can be attached to the baton on or adjacent the end grip at a point distal from the first end of the shaft.
