11652281 · 2023-05-16 · ·

The present disclosure describes a fractal antenna comprising a plurality of antenna elements having a two-dimensional fractal shape and an electrical circuit coupled to the plurality of antenna elements operative to provide electrical power to and maintain phase relationships between the plurality of antenna elements. The electrical circuit provides a signal to the plurality of antenna elements that cause the antenna elements to radiate in the high-frequency (HF) and/or low-frequency (LF) bands. Also described is an antenna comprising a three-dimensional fractal, near-fractal, or super-fractal antenna having a fractal, near-fractal or super-fractal shape.

Press Device

A press device having a cradle, a base plate, a fracturing device, an actuator, a switch, and a body. The base plate is located at a first end of the cradle. The fracturing device is proximally located at a second end of the cradle. The cradle is adapted to work in communication with the base plate to maintain alignment between the baseplate and the fracturing device. The actuator is proximally located to the second end of the cradle. The switch is operably connecting the actuator to the fracturing device. The body holds the cradle, base plate, fracturing device, actuator driven ram, and switch. The preferred embodiment uses a hydraulic ram.

Systems and methods for launching a projectile from a disrupter cannon

A disrupter cannon includes a barrel for launching a projectile. An insert may be used to launch a projectile of a smaller diameter than the projectile launched through the barrel of the disrupter cannon. An insert includes a bore therethrough, a breech-end portion, and a muzzle-end portion. The breech-end portion includes a channel. An O-ring is positioned in the channel of the breech-end portion. The muzzle-end portion includes one or more channels. A respective O-ring is positioned in each channel of the muzzle-end portion. While the insert is positioned in the barrel, the O-rings are configured to form a seal between an outer surface of the insert and an inner surface of the barrel. The projectile with a smaller diameter is launched through the bore of the insert.
