There are various designs of electric cattle prods. Their shape is designed to make them easy to use and handle. They range in length from six inches (usually of a more encased rectangular prism design like a stun gun), to up to six feet. Most are simple designs powered by 9-volt battery or similarly small batteries, to make them small and ...

If there is a power failure, the door opens merely by being pushed or pulled. A new trend is a strike that is quickly reversible from fail safe to fail secure (and back again if ...

This type of lock is similar to the pin tumbler lock and works on a similar principle. However, unlike the pin tumbler lock, where each pin consists of two or more pieces, each wafer in the lock is a single ...
The M61 Vulcan is a hydraulically, electrically, or pneumatically driven, six-barrel, air-cooled, electrically fired Gatling-style rotary cannon which fires 20 mm × 102 mm (0.787 in × 4.016 in) rounds at an extremely high rate (typically 6,000 rounds per minute).
