Abstract: The system is constituted by physical and electrical barriers, with components of sensing and alarm of the first and of connection and activation of the last, all connected to the internal source constituted by set of batteries or conventional electrical system, the last one provided of batteries pack, for coverage of eventual electrical supply failures, for the length of time considered more convenient by the user. The system prevents access to closed or semi-closed enclosures, so that the detection by the sensing and alarm component of the simple approach of intrusion agent at a distance below that established activates the electrical barrier connection and activation component fed by its own sources or conventional, substitutable by the own sources in case of external supply drop, making the entire energized electric barrier practically impregnable to burglary, due to the discharge of high voltage and low amperage, as appropriate.

Abstract: A building security assembly includes a vestibule that may be attached to an entrance of an institution and the vestibule has an entrance and an exit. A first door is hingedly coupled to the vestibule to open and close the entrance. A second door is hingedly coupled to the vestibule to open and close the exit. A metal detection array is positioned within the vestibule to detect metal components of a firearm. A security unit is coupled to the vestibule and is in electrical communication with the metal detection array. The security unit locks each of the first and second doors when the metal detection array detects the metal components of the firearm to inhibit the individual from bringing the firearm into the institution.

Abstract: A device is disclosed to invalidate banknotes in a unit equipped for the storage thereof, comprising an ignition unit (15) placed in the equipped unit (3) in a position adjacent to the banknotes (4) and suitable to generate a flame producing on the banknotes (4) localized burns (4a) of a pre-established and identifiable type, the ignition unit (15) being controlled by activation means (16) sensitive to alarm situations.

Abstract: Device for the protected storage of objects, comprising a closable container having an electrical security shield enclosing a storage space, damaging means (10) for rendering the objects useless, and means (4) for feeding in from the outside a command which disables the damaging means (10), the security shield comprising one or more electrical systems which at least togther extend over essentially the entire surface of the shield and which cooperate with a processing circuit (14) which detects an electrical parameter of each system, and which is capable of delivering an activation command to the damaging means (10) when a detected parameter value deviates from a reference value.

Abstract: A safety box comprises a multi-layered wall having provided therein at least one conductor, which responds by interruption or short-circuiting to damage caused to the wall, and which, if the wall is damaged, activates a circuit connected to said conductor. In response to activation of said circuit, documents contained in said safety box are marked or destroyed via an ignition means. The wall of the safety box is provided with electric shield means. In order to increase the response reliability of the circuit, the invention provides the feature that the shield means is galvanically separate from the circuit.

Abstract: A security box with a door combined with an electricity charged cover, an alarm, an electrical insulator inner cover between the box and charged cover, an electrical insulator outer cover outside of the charged cover, switch means for activating the alarm when the outer cover is traversed and remote switch means for deactivating the charged cover and alarm.

Abstract: A protection system for preventing unauthorized entry through a door member. An electrically charged cover is placed over the door member for electrically shocking anyone who attempts unauthorized entry therethrough. An electrical insulator inner cover is placed between the door member and the electrically charged cover. A first lock is provided to lock the door member in a closed position. A second lock is provided to lock the first lock in a locked position.

Abstract: A safe or safety storage apparatus is mounted for vertical up and down movement above and below a concrete slab. An actuator is provided to effect the movement and a lock is provided to hold the apparatus in the down position. A closure is provided that moves with and covers the apparatus when it is in the down position.

Abstract: An electrode, connected to a fence charger or the like is secured across the bottom of a gate, fence or the like. A shield partially surrounds the electrode to prevent animals from contacting the electrode unless the animals attempt to put their heads under the gate or fence or attempt to crawl under the gate or fence.

Abstract: The invention is an improved method for electrical grounding of plastics coated chain link fabric that is usually used for fences or similar enclosures. The invention provides a method for grounding by employing an insulating coating containing conductive particles to form a continuous linkage or electrical path through and between all wires that compose the fabric. The said fabric, after said continuous linkage or electrical path is established, is then grounded at various intervals along the length of the fence or enclosure and thus effectively electrically grounds the fabric.

Abstract: The invention is an improved method for the electrical grounding of insulation coated chain link fabric that is usually used for fences or similar enclosures. The invention provides a continuous wire at the top or bottom, or both, edges of the erected fabric that electrically connects each of the insulation coated wires which make up the fabric. The continuous wire is then grounded at intervals along the length of the fence or enclosure and thus effectively electrically grounds the fabric. Numerous variations in the configuration of the wire are included in the embodiments for accomplishing the grounding.

Abstract: A security vehicle adapted to prevent unauthorized entry thereinto comprising a base with an electrically conductive frame, an insulated platform on the frame and steerable propelling means for moving the base; a cage defining a security chamber over the platform carried by the base frame with an open electrically conductive framework and see-through security panels closing the openings in the framework. A selectively closable access opening is provided in the front end of the cage and a high voltage, low current charging unit imposes a high voltage, low current charge on the base frame and cage framework.
