La idea de un ingeniero del Ejército de EE. UU. de e convertir el fusil M4 estándar en una pistola de pulso electromagnético recientemente recibió el visto bueno de la Oficina de Marcas y Patentes de EE. UU. , James E. Burke, ingeniero electrónico del Centro de Investigación, Desarrollo e Ingeniería de Armamentos del Ejército de los EE. UU., recibió la patente estadounidense 10.180.309 el martes.
A U.S. Army engineer’s idea to turn the standard M4 rifle into an electromagnetic pulse gun recently got the nod from the U.S. Patent and Trademark Office.
James E. Burke, electronics engineer at the U.S. Army’s Armament Research, Development and Engineering Center, received U.S. patent 10,180,309 on Tuesday, giving the Army intellectual property protections on Burke’s “Electromagnetic Pulse Transmitter Muzzle Adapter.”
This invention would enable a single soldier in a ground unit to destroy enemy electronics, such as small drones or improvised explosive devices, by attaching a special blank-firing adapter to their rifle’s muzzle, then firing a shot.
The muzzle attachment contains a piezoelectric generator, powered by firing the blank cartridge, which creates an electromagnetic pulse directed by a horn antenna.

Most of the Army’s directed-energy weapons are large, vehicle-mounted systems. For example, the High Energy Laser Mobile Test Truck is an 8-wheeled behemoth.
“A need exists for an inexpensive, one-man portable directed energy weapon,” according to the Army patent, which you can download along with Burke’s slides below.
Troops “already carry rifles. Why not use something that every soldier already carries?” Burke told Defense One.
A prototype has been tested, its effective range has not been disclosed, but Burke indicated that larger caliber ammunition may affect performance.

TechLink, the Department of Defense’s national partnership intermediary for technology transfer, can help businesses interested in productizing DoD technology learn more about patent licensing. Through technology transfer, DoD inventions are made available to businesses and entrepreneurs for use in new products and services.
The Armament Research, Development and Engineering Center has over 400 available technologies.
A patent license confers the right to practice the invention for commercial purposes and often includes related data and technical knowledge. License fees paid to the laboratory are typically negotiable.
