摘要： One embodiment includes an electrometer system. The system includes a sensor cell comprising alkali metal atoms within and an optical beam system configured to provide at least one optical beam through the sensor cell to provide a Rydberg energy state of the alkali metal atoms, the at least one optical beam exiting the sensor cell as a detection beam. The system also includes a signal generator configured to generate a radio frequency (RF) tuning signal. The system also includes a waveguide extending along a length of the sensor cell, the waveguide being configured to propagate the RF tuning signal in the sensor cell to tune at least one energy state of the alkali metal atoms relative to the Rydberg energy state. The system further includes a detection system configured to monitor the detection beam to detect an external signal based on monitoring the detection beam.

摘要： A compact munition antenna system that includes a curvilinear transmit antenna on a top and bottom of a ring-shaped substrate, and a curvilinear receive antenna on the top and bottom of the substrate. The transmit antenna and receive antenna are positioned opposite one another on the substrate, and are separated by a pair of isolation barriers to reduce coupling of the two antennas. The munition antenna system may be mounted on a metal cylindrical portion of a guidance system in a nose section of the munition, using a vertical convex surface of the cylindrical portion and a horizontal surface of the munition as a reflector for improving antenna performance.

摘要： An explosive device, such as a missile, artillery round, aerial bomb, mortar round, or mine, that utilizes a wall structure that upon detonation provides displacement of smaller fragments interstitially between larger fragments. The displacement of the smaller fragments into the interstitial spaces at detonation creates an expanding fragmentation curtain that momentarily contains expanding gases to increase the impulse pressure of the explosion, thereby increasing the kinetic energy imparted to the fragments. In some embodiments, the wall structure includes ordered layers of preformed metal fragments encased in binder material that suspends the fragments in a desired arrangement prior to detonation.

摘要： A powered projectile having a nose portion, a body portion, a tail portion, and a central axis. In various embodiments a collar is rotatably mounted to a control support portion with a plurality of aerodynamic surfaces thereon for despinning the collar. An alternator configured as an axial flux machine with a stator arranged can be axially adjacent to one or more rotors, the stator including a plurality of windings and the one or more rotors each including a plurality of permanent magnets arranged about the face of the respective one or more rotor. In various embodiments the projectile includes an assembly of projectile control circuitry. In one or more embodiments, upon relative motion of the rotor with respect to the stator, magnetic flux from the magnets interacts with the windings of the stator and passes through an air gap between the one or more rotors and stator.

摘要： A machine for manufacturing tube elements comprised of tape strips. The machine includes a shaft, a disk mounted to one end of the shaft, a motor coupled to an opposite end of the shaft, and a plate mounted to the shaft. The plate includes a plurality of spools mounted to the plate, where a separate one of the strips is wound on each spool. In one embodiment, the machine further includes a rail positioned adjacent to the disk, a slide slidably secured to the rail and including an end support configured to hold ends of the tape strips, and an indexer configured to pull the slide on the rail away from the disk. The tape strips are unwound from the spools when the indexer pulls the slide in a manner so that the tape strips ride in a spaced apart manner around the disk to form the tube element.

摘要： A power limiter for limiting power provided to an electronic device. The power limiter includes a waveguide that receives an input signal to be sent to the electronic device, an LaCoO3 film formed to one side of the waveguide, an LaCoO3 film formed to an opposite side of the waveguide, a grounded element formed to one of the LaCoO3 films and a grounded element formed to the other LaCoO3 film. When the heat level in the LaCoO3 films is below a predetermined threshold, the LaCoO3 films are an insulator and the input signal propagates through the waveguide to the electronic device, and when the heat level in the LaCoO3 films goes above the threshold, the LaCoO3 films become conductive, and the input signal is shunted through the LaCoO3 films to the grounded elements.

摘要： A continuous filament additive manufacturing machine for building a part by laying down a continuous mono-filament or composite filament material layer by layer on a tool or substrate. The machine includes a system, such as a robot, operable to move in three degrees of freedom, and a placement module coupled to the system and being configured to deposit the continuous filament material. The placement module includes a guide for guiding the material to the part and an ultrasonic compaction device for compacting the material as it is being deposited from the placement module. The compaction device includes an ultrasonic horn having at least one guide hole through which the material passes before it is laid down and compacted. The ultrasonic horn is ultrasonically vibrated to melt or flow the material and cause the material to fuse and be compacted to the tool or substrate.

摘要： One embodiment includes an electrometer system. The system includes a sensor cell comprising alkali metal atoms within, and an optical beam system configured to provide at least one optical beam through the sensor cell to provide a first Rydberg energy state of the alkali metal atoms, the at least one optical beam exiting the sensor cell as a detection beam. The system also includes a tuning laser configured to generate a tuning beam having a predetermined tuning frequency between the first Rydberg energy state and an intermediate energy state of the alkali metal atoms. The system further includes a detection system configured to monitor the detection beam to detect an external signal having a frequency that is approximately equal to an energy difference between the first Rydberg energy state and a second Rydberg energy state based on monitoring the detection beam.

摘要： Methods for fabricating high-temperature composite structures (e.g., structures comprising carbon-carbon composite materials or ceramic composite matrix (CMC) materials and configured for use at temperature at or exceeding about 2000° F. (1093° C.)) include forming precursor structures by additive manufacturing (“AM”) (e.g., “3D printing”) with a filament drawn from a spool. The precursor structures are exposed to high temperatures to pyrolyze a precursor matric material of the initial 3D printed structure. A liquid resin is used to impregnate the pyrolyzed structure, to densify the structure into a near-net final shape. Use of expensive and time-consuming molds and post-processing machining may be avoided. Large, unitary, integrally formed parts conducive for use in high-temperature environments may be formed using the methods of the disclosure.
