Abstract: The invention relates to a carrying case with a theft prevention clamp. It is especially designed for laptop computers left in public places, but may also be used to prevent other items from being stolen. The clamp is designed to removably fasten the carrying case to a table, but may also be used on shelves or other objects with similarly shaped surfaces. The clamp has a flexible portion and a rigid portion. The carrying case has an upper portion and a lower portion, which are pivotally connected. There is a lock for securing the upper portion to the lower portion when they are in a closed position. A keyhole switch activates a battery-powered electric motor to extend the clamp when a key is inserted, if the key is turned clockwise, or to retract the clamp, if the key is turned counterclockwise. Once the clamp is extended, it and the lower portion of the carrying case can be inserted around a table or other object with similar surfaces.

Abstract: Apparatus for opening, or removing without damage, automotive side-bar type ignition locks, comprises a combination tool with a plurality of projections extending horizontally and forwardly from the combination tool to engage the lock's keyway, at least one balanced pair of recesses in the lock's face, or, optionally, when the tool is used as a lock-remover, the inner walls of the lock's hollow wing-nut cylinder cap. When used as a lock-forcing opener, the combination tool is placed in position on the lock cylinder's face and a conventional wrench gripping the tool's hexagonally-shaped portion is turned to create torque applied by the tool's projections against the walls of the lock's recesses, forcing the lock cylinder to turn to its ON position and start the vehicle's engine.

Abstract: A firearm-securing device providing tamper resistance features which device includes a keyway that operates a threaded rod which, in turn, controls spring-loaded cams that obstruct a tubular area including a chamber, a barrel, and a muzzle of a firearm. The cams have either fixed or articulated contact pads. Operating the keyway in clockwise rotation causes the cams to wedge against the inner chamber and barrel surfaces, locking the device in place. Counterclockwise keyway rotation unseats the cams, allowing the device to be remove from the chamber and barrel and thus allow operation of the firearm. The device includes several components designed to minimize tampering of the device itself as well as tampering of the firearm.
