A distributed ordnance system comprises a plurality of ordnance controllers and a plurality of firing units. Each ordnance controller of the plurality of ordnance controllers may be operably coupled with at least one firing unit of the plurality of firing units. Each ordnance controller may be configured to provide power signals to the at least one firing unit coupled therewith, and communicate with the at least one firing unit for initiation of an ordnance event. A multiple stage ordnance system may comprise a first stage and a second stage that each include an ordnance controller configured to control operation of an ordnance event, and at least one firing unit to initiate the ordnance event. Related methods for constructing a multiple stage ordnance control system and controlling initiation of an energetic material are also disclosed.

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.

A spin sensor (300) and method of detecting fuze spin are disclosed. The spin sensor (300) includes a fuze housing (220) , a sense weight (390) and a rotating induction device (310). The rotating induction device (310) comprises a first rotatable element affixed to the fuze housing (220) and a second rotatable element affixed to the sense weight. The second rotatable element is mechanically coupled to the first rotatable element such that it may rotate relative to the first rotatable element. In addition, the second rotatable element is inductively coupled to the first rotatable element such that the relative rotation between the first rotatable element and the second rotatable element generates a spin signal on an electrical connection to the rotating induction device (310). The spin signal may be compared to a suitable spin profile to determine if a valid spin environment is present.

Optical devices include a doped glass material in which the dopant facilitates the transmission of energy out from the glass material. The doped glass may not significantly absorb a selected wavelength of laser radiation to be manipulated by the optical devices. The dopant may comprise one or more of a transition metal element, an actinide element, and a lanthanide element. Laser systems include at least one such optical device and a laser device configured to emit a beam to be manipulated by the optical device. Methods for forming optical devices and laser systems including such optical devices include dispersing a dopant within a glass material to form, and forming the glass material into a body having a size and shape configured to manipulate a beam of radiation emitted by a laser device. The dopant is selected to comprise a material that facilitates the transmission of energy out from the glass material.

A material preparation device (100) is provided. The material preparation device (100) includes a bias-ply assembly (105), a feedstock assembly and an application head (130). The bias-ply assembly (105) is configured to pass a bias-ply backing (146) material along a first path. The feedstock assembly (103) is configured to pass a feedstock (116) along a second path that crosses the first path at a select angle. The feedstock (116) includes resin pre-impregnated fiber reinforced material (pre-preg,300) having the fibers at a first orientation relative to an edge of the feedstock (116). The application head (130) is configured to transfer the pre-preg (300) from the feedstock (116) to the bias-ply backing material (146) at a location where the first path crosses the second path to form a bias-ply (158) with the fibers of the pre-preg (300) having a second different orientation relative to an edge of the formed bias-ply (158).
摘要:
Provided herein are methods and systems of producing hydrogen using ammonia borane, which has a high hydrogen density while being stable and easily stored. Ammonia borane may be exothermically reacted with a strong oxidizer, such as a mixture of hydrogen peroxide and water. The reaction between ammonia borane and the strong oxidizer may occur spontaneously and may produce heat. Unreacted ammonia borane may be exposed to and thermally decomposed using the heat produced during the exothermic reaction between ammonia borane and the strong oxidizer. The heat may be retained by performing the reactions in a vessel or reactor including a material capable of retaining the heat. A high gravimetric hydrogen yield is obtained from the reaction of ammonia borane with hydrogen peroxide and the thermal decomposition of unreacted ammonia borane. Hydrogen production using the methods and systems may yield a high gravimetric hydrogen content of at least about 10%.
