A self-defense system includes a first sleeve retainably securing a deterrent item. A second sleeve is laterally coupled to the first sleeve and houses a knife. The knife has a handle and a tip. A closed portion of the second sleeve houses the knife handle. An open portion of the second sleeve flexibly covers the knife tip. A hand strap is laterally adjacent to the second sleeve and coupled to at least one of: the first sleeve and the second sleeve. The hand strap is sized and shaped to secure the self-defense system about a hand of a user.

The present invention provides a compressed air artificial wind system including compressed air storage device, compressed air discharge device, artificial wind system base and controller; also a firefighting equipment including an extinguishing agent tank and the compressed air artificial wind system. The compressed air storage device includes row tubes and manifolds for production and storage of high/ultra-high pressure compressed air; the compressed air discharge device includes intake pipe, expansion chamber, Laval nozzle and wind-blowing tube; the artificial wind system base is built as an infrastructure. Large quantity of high/ultra-high pressure compressed air under control from the compressed air storage device and through the compressed air discharge device to spray out generating artificial wind with large air volume and high wind speed for meteorological control, forest firefighting, air defence and coastal defence, respectively.

A cannister deployment apparatus for discharge of gas cannisters within a target building includes a battering ram arranged for being carried on a vehicle for penetrating into the building when impacted on the building by the vehicle. The battering ram has a housing with a plurality of receptacles for receiving the cannisters to be discharged respectively therein. The receptacles include (i) one or more release receptacles arranged to release the respective cannister from the release receptacle upon actuation by a release actuator so that the cannister is discharged from the housing, and (ii) one or more discharge receptacles enabling actuation of the respective cannister into an active state while the cannister remains supported within the discharge receptacle upon actuation by a discharge actuator arranged to trigger a release lever of the cannister in the discharge receptacle into an active state.
