  • Patent number: 9683821
    Abstract: A liner assembly for an explosively formed projectile device may include a reactive material liner and a primary liner configured to form into a projectile responsive to initiation of an explosive material. The reactive material liner may be configured and formulated to increase the velocity of the projectile after formation thereof. An ordnance device for generating an explosively formed projectile may include a case, an explosive material, and a reactive material liner and a primary liner configured, in combination, to form into a projectile. An explosively formed projectile may include a deformed primary liner and a deformed reactive material liner having an ignited portion increasing the velocity of the projectile. Methods of explosively forming a projectile may include explosively expelling a primary liner and a secondary liner and increasing the velocity of the projectile by combusting at least a portion of the secondary liner.

  • Publication number: 20120274147
    Abstract: Techniques are described for wireless energy transmission and projecting magnetic fields over relatively long near-fields. In one example, a device for transmitting near-field energy comprises at least one source that generates a radiofrequency (RF) signal, an antenna that generates near-field signals from the RF signal, and a plurality of sub-wavelength sized elements that form a lens in communication with the antenna that captures the near-field signals, generates near-field energy, and re-directs the near-field energy toward an object in the near-field of the lens, where the sub-wavelength sized elements are disposed about the antenna.
