ELECTROMECHANICAL PULSE DEVICE OF IMPACT-MECHANICAL AND ELECTROMAGNETIC EFFECT Russian patent published in 2016 - IPC G06F12/14 B06B1/04 H02K33/02 

FIELD: information technology.

SUBSTANCE: invention relates to information security, wherein destruction of information is carried out based on both obtaining signals on unauthorised intrusion, and at desire of user. Electromechanical pulse device of impact-mechanical and electromagnetic action consists of ferromagnetic frame 1, inside of which there are coaxially arranged inductor 2, electroconductive armature 3 and ferromagnetic head 4. One flat surface of electroconductive armature 3 is connected to power disc 5. Head 4 is made with sharpened tempered end directed towards digital information storage 6. Inside frame 1 there are multiple levers, each of which consists of two opposite arms 7 and 8, separated by support 9. Flat end 4v of head 4 interacts with arm of lever 7, and power disc 5 interacts with arm of lever 8. Supports of levers 9 are fixed relative to detachable cover of frame 1. Inductor coil 2 is wound on guide sleeve 10 of head 4. Portion of surface area of power disc 5 interacting with arm of lever 8, protrudes. To increase height of protruding part of power disc 5 is equipped with pusher 11 made in form of a ring.

When producing a signal inductor 2 is excited from a charged capacitive storage. Flowing pulse current in inductor 2 excites magnetic field, destroying information in storage 6. Magnetic field of inductor excites 2 eddy currents in electroconductive armature 3. Electrodynamic force thus generated causes displacement of latter together with power disc 5 from inductor. Power disc 5 via pusher 11 acts on arm of levers 8, end of which moves in direction from inductor 2. Levers turn relative to fixed supports 9 and ends of opposite arms of levers 7 move in direction of inductor 2 to apply force action on flat end 4 of head 4. Head 4 moves in direction of inductor, punching with its sharpened end digital storage 6.

EFFECT: technical result is improved efficiency of protecting information stored on digital media in case of leakage due to impact-mechanical and electromagnetic effects.
