Abstract: A distributed simulation system is composed of simulator stations linked over a network that each renders real-time video imagery for its user from scene data stored in its data storage. The simulation stations are each connected with a physics farm that manages the virtual objects in the shared virtual environment based on their physical attribute data using physics engines, including an engine at each simulation station. The physics engines of the physics farm are assigned virtual objects so as to reduce the effects of latency, to ensure fair fight requirements of the system, and, where the simulation is of a vehicle, to accurately model the ownship of the user at the station. A synchronizer system is also provided that allows for action of simulated entities relying on localized closed loop controls to cause the entities to meet specific goal points at specified system time points.

Abstract: In an electron gun for use in a TWT, klystron, linear accelerator or other electron device, an electron gun header assembly and an input body assembly are coupled using a flexible bellows that allows the distance between the cathode and anode to be varied. As such, the perveance of the electron gun can be tuned, and the cathode magnetic field optimized for efficient operation. In addition, an external magnetic shield is adapted to be translated along the axial dimension of the electron gun to further optimize the cathode magnetic field and focusing characteristics to achieve improved electron gun performance.

Abstract: To overcome problems with vergence, a binocular head mounted display (HMD) is used in a simulator in which an out-the-window scene is displayed in real time on a screen arrangement. Imagery for the left and right eyes of the HMD is derived by generating a starting HMD image for a Cyclops viewpoint between the user's eves, and then rendering respective views for each eve from the position of the eye in a virtual 3D model of the screen arrangement, wherein the starting HMD image is frustum projected against the screen arrangement of the 3D model.

Abstract: An overmoded distributed interaction network is provided that generates high peak and average RF power amplification at high frequencies. A series of overmoded cavities are bounded by parallel or concentric grids that may be separated by metallic spacers adapted to function as a photonic bandgap circuit to suppress competing electromagnetic modes. The selected electromagnetic modes have wavelengths much shorter than the lateral dimension of the grids, allowing the beam-wave interaction to be distributed transversely for improved interaction efficiency. The grids may optionally be slotted and arranged to provide a serpentine traveling wave tube configuration.

Abstract: Components for use in vacuum electron devices are fabricated from highly oriented pyrolytic graphite (HOPG) and exhibit excellent thermal conductivity, low sputtering rates, and low ion erosion rates as compared to conventional components made from copper or molybdenum. HOPG can be reliably brazed by carefully controlling tolerances, calculating braze joint material volume, and applying appropriate compression during furnace operations. The resulting components exhibit superior thermal performance and enhanced resistance to ion erosion and pitting.

Abstract: Techniques for detecting wireless devices that are signaling in high proximity to a convoy or other operation and preventing messages from reaching the wireless devices. One class of the techniques uses surgical jamming methodologies that minimize power consumption and collateral interference, while being maximally inconspicuous; another class uses baiting beacons to prevent the messages from reaching the wireless devices. Still another class of techniques denies wireless devices access to a wireless network. An exemplary embodiment applies the techniques to wireless devices and beacons in a GSM network.

Abstract: A novel magnetron achieves increased power output at high frequencies by replacing a typical resonant cavity with a slow-wave waveguide structure. Waveguides built into the anode body sustain oscillations having phase change coefficients of 2*pi*n radians per section, where n is a positive integer. The magnetron is capable of supporting RF oscillations at frequency harmonics of the fundamental frequency, permitting it to operate at frequencies double or quadruple that of a similarly sized conventional magnetron.

Abstract: Techniques for generating an interloping beacon which can control the behavior of a target wireless device on a CDMA frequency channel without noticeably altering the behavior of non-target wireless devices which share the frequency channel of the target wireless device's live beacon. The interloping beacon is an override beacon which overrides the live beacon's pilot channel and a control message on a code channel on which control messages may be addressed to the target wireless device. The override beacon provides the overriding pilot and the overriding control message only as long as is required for the target wireless device to respond to the overriding control message. The period of time during which the overriding pilot and the overriding control message are generated for the override beacon is so short that only the target wireless device responds without noticeable effect on collateral wireless devices.

Abstract: Data recording systems (100) and methods (400) for synchronizing data of a plurality of different data types on a single packet (300). The methods involve: receiving the data and an audio frame containing voice data and timing data communicated over a plurality of channels; generating, in response to the reception of the audio frame, a combined packet on which the audio frame and at least a portion of the data are time synchronized to each other; and substantially simultaneously storing the combined packet in a primary data store and a secondary data store of a data recorder for subsequent use in reconstructing events leading up to a crash of a land vehicle, aircraft or vessel. The portion of data may include data link data, flight data and/or image/video data. The channels may include a cockpit channel and a plurality of pilot channels.
