The last line of defence – right on the soldier.

The problem

Drones cause 70–80% of personnel casualties at the front¹, and FPV drones alone account for 60% of Russian losses². The upper tiers of layered counter-drone defence (radars, jammers, interceptor drones) do not protect the individual soldier: kinetic self-defence is the last line, which a soldier must handle alone³ – while the full reaction chain takes 4–5 seconds, the engagement window is 2–3 seconds⁴, and at night the drone cannot be detected with the naked eye⁵. No system on the market today provides a closed chain from detection to effective fire at the level of the individual soldier.

The solution: an integrated sensor–effector system

The “Smart Shield” concept integrates two complementary Hungarian patent portfolios. “Smart Ear”, using a passive acoustic sensor array distributed across the soldier’s uniform and on-device artificial intelligence, gives warning while the drone is still below the threshold of human hearing: it indicates the drone’s direction by vibration and its distance and friend-or-foe classification on a display – at night, in fog and in smoke, and even against fibre-optic-controlled, unjammable drones. “Smart Ammo” makes the same soldier’s small arm multifunctional: at the push of a button, without changing ammunition, it switches between single-projectile and fragmentation mode, and is suitable for burst fire as well. The weapon-mounted display and the mode selector form a natural common user interface; in the electromechanical version the threat classification can also recommend or perform the mode switch automatically.

Portfolio strength and market

Together, the two families of inventions cover both the sensor and the effector side – this rare, full-value-chain IP position raises a significant barrier to entry for competitors. The counter-drone market will grow from ~USD 2.7 billion in 2024 to USD 11–15 billion by 2030⁶; the EU’s EUR 400 million drone defence programme and EDDI (the “drone wall”), as well as the US Army’s requirement for acoustic detection for infantry soldiers⁷, are direct signals of demand. The system is dual-use: the sensor branch can be used on its own for disaster-relief victim search⁸, and the complete system for law-enforcement and critical-infrastructure protection tasks; it is also suitable for further development towards NATO standardisation.

Business objective

The owner’s objective is the complete and irrevocable sale of the exploitation rights of the portfolios. The patent procedures are at an early stage, so the future owner can still actively shape the levels, directions and global coverage of protection, with effect retroactive to the original filing dates. Acquiring both portfolios together – exclusive ownership of the integrated system – offers the opportunity to establish a long-term international market monopoly at a time of radical transformation in the defence industry.
