Abstract: A weapon for firing cased telescoped (CT) ammunition includes a barrel. a chamber cavity aligned with the barrel, and a translating chamber member defining a chamber for holding a CT round for firing. The chamber member moves between a firing position in the chamber cavity and an ejection/loading position for ejecting a spent CT round and receiving a next CT round. A breech member closes a rear end of the chamber. A carrier performs a counter-recoil operation in which (1) the chamber member is moved from the ejection/loading position to the firing position with the next CT round therein, and (2) the breech is urged into a closed position against the next CT round in the chamber to remove headspace before the next CT round is fired from the weapon.

Abstract: A cased telescoped cartridge that includes a cylindrical case surrounding a projectile, a front end through which the projectile exits when the cased telescoped cartridge is fired, and a thermal protective insert located at the front end. The thermal protective insert insulates the cased telescoped cartridge from heat emanating from a barrel of a firearm into a chamber of a firearm when the cartridge is loaded into the chamber of the firearm. The thermal protective insert is made up of at least one thermally insulating material, and is integrated into the front end of the cased telescoped cartridge.

Abstract: A technique is directed to operating an unmanned aerial vehicle (UAV) having a fuselage defining a flight direction of the UAV and wing-plate assemblies that propel the UAV in the flight direction defined by the fuselage. The technique involves providing, while the flight direction defined by fuselage of the UAV points vertically from a takeoff location on the ground, thrust from propulsion units of the wing-plate assemblies to fly the UAV along a vertical takeoff path. The technique further involves maneuvering, after the UAV flies along the vertical takeoff path, the UAV to align the flight direction along a horizontal flight path that is perpendicular to the vertical takeoff path. The technique further involves providing, after the UAV flies along the horizontal flight path, thrust from the propulsion units of the wing-plate assemblies to land the UAV along a vertical landing path that is perpendicular to the horizontal flight path.

Abstract: A firearm for firing cased telescoped (CT) ammunition cartridges that includes a split chamber configured to fully support a CT cartridge when it is fired, and that includes i) a dynamic rear chamber portion defining a pocket in a face of a bolt, and ii) a static front chamber portion that is integral to the barrel and separate from the bolt. A cartridge extraction mechanism engages the CT cartridge prior to the CT cartridge being fired, and holds the CT cartridge in the pocket in the bolt face as the bolt moves rearward to pull the CT cartridge out of the static front chamber portion and into an ejection position. An ejector is operable to eject the CT cartridge from the pocket in the face of the bolt when the CT cartridge reaches the ejection position.

Abstract: A weapon for firing cased telescoped (CT) ammunition includes a barrel, a chamber member and a carrier assembly. The chamber member defines a chamber for a CT round for firing, and translates between a firing position aligned with the barrel and an ejection/loading position. The chamber member is spring-biased toward the firing position. The carrier assembly carries the firing pin and (1) performs a recoil in which a carrier and rammer move rearward from a battery position to bring the next CT round into a ramming position and to move the chamber member from the firing position to the ejection/loading position, and (2) performs a counter-recoil to return to the battery position and cause the rammer to push the next CT round into the chamber. The chamber member is released for biased return to the firing position for a next firing cycle.

Abstract: An articulated support includes a base and pitch-roll-yaw assembly having a pitch/roll subassembly and a yaw subassembly. The pitch/roll subassembly includes a central member configured for spring-loaded rotation about a pitch/roll axis, and the yaw subassembly has a U-shaped member configured (a) at end portions to engage under-wing connection lugs of an unmanned aircraft system (UAS) and (b) at a central portion to mate to the central member of the pitch/roll subassembly in a rotatable manner providing for rotation of the yaw subassembly about a yaw axis. The pitch/roll subassembly and yaw subassembly are further co-configured to define first and second fixed yaw positions in which a fuselage of the UAS is, respectively, parallel to and perpendicular to the pitch/roll axis, permitting roll motion and pitch motion of the UAS when mounted on the articulated support.

Abstract: A magazine for storing cased telescoped (CT) cartridges. The magazine includes vertically extending side-wall ribs that project inwards into a loading channel. The side-wall ribs are positioned in alignment with a circumferential groove in each CT cartridge. The side-wall ribs prevent a backwards oriented CT cartridge from being pushed from the loading position through the loading channel into a body of the magazine. A moveable lip at the top of the magazine may move out of the way when the magazine is attached to a firearm, to allow the CT cartridge located in the loading position to be fed vertically out of the top of magazine. Each CT cartridge may include a thermal protective insert that provides thermal insulation from heat emanating from a barrel of a firearm when the CT cartridge is located in a chamber of the firearm.

Abstract: A technique for adaptively disrupting UAVs detects a target UAV using a camera, monitors the target UAV's communications using a directional antenna aligned with the camera, and attempts to communicate with the target UAV to request that it land, fly away, or return to launch. With the camera trained on the UAV, the directional antenna detects down-link signals from the UAV, which the UAV may employ to communicate with a ground-based controller. Control circuitry analyzes the down-link signals and generates a disrupting signal based thereon. The disrupting signal shares characteristics with the down-link signal, such as its protocol, bit rate, and/or packet length. The directional antenna transmits the disrupting signal back toward the UAV to affect the UAV's flight.

Abstract: A technique for testing an electronic UUT by a test apparatus includes obtaining multiple DFTs of a test signal received from the UUT with the test apparatus configured differently for obtaining each DFT. The resulting DFTs include both valid content representing the test signal and invalid content introduced by the test apparatus. The improved technique suppresses the invalid content by generating a corrected DFT, which provides minimum magnitude values for corresponding frequencies relative to the test signal across the multiple DFTs.

Abstract: An unmanned aerial vehicle (UAV) platform includes a stationary base constructed and arranged to reside over a fixed location on a surface (e.g., a ground location, a ship's deck, a trailer or other vehicle, etc.). The UAV platform further includes a set of UAV interfaces constructed and arranged to interface directly with a UAV (e.g., a launcher, a net apparatus, etc.). The UAV platform further includes a turntable assembly which couples to the stationary base. The turntable assembly is constructed and arranged to couple to each UAV interface and control angular direction of that UAV interface over the fixed location. A method of operating a UAV platform includes deploying the UAV platform over a fixed location, preparing a UAV interface on a turntable assembly of the UAV platform, and rotating the turntable to control angular direction of the UAV interface over the fixed location.

Abstract: A technique that uses a thermoelectric generator for generating electrical power employs a safe, initially dormant, stable, non-radioactive fuel sample which is activated on-demand by a neutron source to initiate and control activation of the fuel sample. The technique allows thermoelectric generators to be fully assembled and stored for extended periods of time before they are deployed for use, and then activated on demand only when the need arises for them to generate power.

Abstract: A technique is directed to launching an unmanned aerial vehicle (UAV). The technique involves positioning a UAV launcher over a ground location. The technique further involves installing, after the UAV launcher is positioned over the ground location and prior to launching the UAV, an anchor into the ground location to anchor the UAV launcher to the ground location. The technique further involves operating, after the UAV launcher is anchored to the ground location, the UAV launcher to impart launching force onto the UAV to launch the UAV, the anchor holding the UAV launcher substantially in place at the ground location to minimize energy loss as the UAV launcher imparts launching force onto the UAV. In some arrangements, the UAV launcher is capable of pivoting while remaining anchored between launches to accommodate changes in wind direction while maintaining substantial connection to the ground location for enhanced consistency and performance.

Abstract: A UAV includes a body. The body defines a payload opening 14. The payload opening is circular, but any shape may be used. A payload of the UAV is arranged in the payload opening. The payload may be a camera, sensors, a package, etc. A payload shroud may be installed which prohibits or reduced ingress of foreign material via payload opening. A payload shroud may include a diverter. The diverter may act as a barrier wall preventing the water or debris from entering the body of the UAV. The diverter should fit flush with the payload opening in the body of the UAV.

Abstract: An aircraft hybrid fuel system includes a main tank and a set of flexible bladders, the main tank and the set of flexible bladders defining a fuel containment space. The system further includes a set of pathways coupling the set of flexible bladders to the main tank. The set of pathways is constructed and arranged to vent gas out of the set of flexible bladders into the main tank while fuel from a fuel source is provided into the fuel containment space defined by the main tank and the set of flexible bladders. Along these lines, each flexible bladder can be provisioned with a fuel port to provide fuel, and a separate vent port to vent gas to the main tank.

The technique further includes controlling, by the processing circuitry, the vehicle based on whether the vehicle is currently experiencing tire skid.

Abstract: A technique is directed to launching an unmanned aerial vehicle (UAV). The technique involves attaching a UAV launcher to a hand-held weapon, and installing a UAV onto the UAV launcher while the UAV launcher is attached to the hand-held weapon. The technique further involves activating the hand-held weapon to launch the UAV into flight from the UAV launcher. Since a user already may be carrying the hand-held weapon for firing ammunition, the user simply needs to further carry the UAV launcher and the UAV which, in some situations, can be packaged into an easy-to-carry container such as a backpack, a carrying case, and so on.

Abstract: A parser may be graphically modified without needing to directly alter the parser software and may be graphically modified to adjust for extensibility of the source test program language. The parser may be graphically modify to adjust for extensibility of the destination test program language and to translate a new text based test program language not inherently built into the parser.

Abstract: Techniques involve attenuating noise from engine exhaust from an engine. For example, an apparatus includes a first tube having an input end which receives the engine exhaust from the engine, and an output end which outputs the engine exhaust. The apparatus further includes a second tube which encircles the output end of the first tube. The second tube has an exhaust end through which the engine exhaust outputted by the output end of the first tube is allowed to escape, and a resonator end which is opposite the exhaust end. The apparatus further includes a reverse resonator disposed at the resonator end of the second tube. The reverse resonator defines a reverse resonator chamber and a reverse resonator chamber diameter which is larger than a second tube diameter defined by the second tube.
