摘要： A switching power supply (102) for a night vision device (100) converts a battery (113) voltage to high DC voltages for powering photocathode (103), screen (105), and micro-channel plate MCP (104) of the night vision device (100). The switching power supply (102) generates and adjusts a photocathode voltage instruction signal having a duty cycle based on the difference between a reference photocathode voltage and the photocathode voltage circuit output voltage. The switching power supply (102) generates and adjusts a screen voltage instruction signal having a duty cycle based on the difference between a reference screen voltage and the screen voltage circuit output voltage. The switching power supply (102) performs automatic brightness control and auto-gating without directly sensing the output load current.

摘要： A vehicle, especially a maritime vessel, is provided with an autogyro drawn by a tether. The tether contains mechanical strengthening components that enable it to securely retain the autogyro to the vehicle. The tether also contains two electrical conductors carrying different phases of AC power to the autogyro, and four optical fibers carrying optical data signals to and from the autogyro electronic payloads and avionics control circuitry. Signal converters at ends of the tether convert a wide range of electrical or wireless signals to optical data signals for transmission along the tether, and then back into the original electrical signal format for use by the autogyro or vehicle electronics.

摘要： 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.

摘要： A host computer supports a virtual guest system running thereon. The host system has a firewall that prevents it from communicating directly with the Internet, except with predetermined trusted sites. The virtual guest runs on a hypervisor, and the virtual guest comprises primarily a browser program that is allowed to contact the Internet freely via an Internet access connection that is completely separate from the host computer connection, such as a dedicated network termination point with its specific Internet IP address, or by tunneling through the host machine architecture to reach the Internet without exposing the host system. The virtual guest system is separated and completely isolated by an internal firewall from the host, and the guest cannot access any of the resources of the host computer, except that the guest can initiate cut, copy and paste operations that reach the host, and the guest can also request print of documents. The host can transfer files to and from a virtual data storage area accessible by the guest by manual operator action. No other transfer of data except these user initiated actions is permitted.

摘要： Pixel-level monolithic optical element configurations for uncooled infrared detectors and focal plane arrays in which a monolithically integrated or fabricated optical element may be suspended over a microbolometer pixel membrane structure of an uncooled infrared detector element A monolithic optical element may be, for example, a polarizing or spectral filter element, an optically active filter element, or a microlens element that is structurally attached by an insulating interconnect to the existing metal interconnects such that the installation of the optical element substantially does not impact the thermal mass or thermal time constant of the microbolometer pixel structure, and such that it requires little if any additional device real estate area beyond the area originally consumed by the microbolometer pixel structure interconnects.

摘要： 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.

摘要： An active electronically steered cathode (AESC) applies one or more electromagnetic modes to an input cavity, similar to that used in an inductive output tube. The structure and superposition of these modes creates local electric field maxima, causing the electron emission site or sites to move or be distributed across the surface of the cathode. Changing the amplitude, phase, or frequency of the modes provides time-variable control of the electric field profile, thereby generating electronically steered electron beams. One embodiment employs a pair of orthogonal TM modes driven out of phase, causing the electric field maximum to rotate around an annular cathode, producing a helical beam. Slots in the control grid may be used to segment the helical beam into discrete bunches to provide additional density modulation.

摘要： An electron gun comprises a shell having distal and proximal ends, a cathode structure disposed within the shell and having an electron emitting surface, an anode physically coupled to the shell at the distal end and spaced a fixed distance from the emitting surface, and a plurality of leads adapted to apply a voltage to the cathode structure with respect to the anode sufficient to cause emission of the electrons from the emitting surface. The anode has an aperture for passage therethrough of the beam of electrons emitted by the emitting surface. A first insulator is disposed within the shell proximal to the cathode structure. The first insulator has plural apertures having respective sizes in relation to corresponding ones of the plurality of leads such that the plurality of leads pass therethrough without contacting the first insulator. The first insulator provides stand-off for the voltage between the anode and cathode. A second insulator is disposed with the shell proximal from the first insulator. The second insulator also has plural apertures permitting the plurality of leads to pass therethrough; however, the plurality of leads are tightly engaged within corresponding ones of the plural apertures of the second insulator to provide a vacuum barrier of the shell. A thermal choke is coupled between the first insulator and second insulator to provide an indirect thermal path therebetween.

摘要： An integrating capacitor circuit (Figure 1C) for an integrating amplifier and related methods are disclosed that allow for efficient detection of currents or charges, particularly those produced by pixel cells in a detector image array. By placing a capacitor- connected field effect transistor (FET 120B) in parallel with an integration capacitor (120A) and setting its gate voltage to a selected voltage level, the current or charge from the detector depletes the charge on the gate of the FET capacitor (120B) while integrating on the capacitor (120A). In addition, the gate voltage level can be adjusted to modify the current depleting characteristics of the capacitor-connected FET (120B). The resulting operation of this integrating circuitry provides significant resulting advantages for the integrating amplifier.

摘要： Systems and methods are disclosed for non-linear colorization in imaging systems. More particularly, colorization of video outputs of thermal imagers (which are typically black and white gray scale imagers) are provided that enhance desired aspects of the displayed image. Specifically, the color in the video output has direct relationship to the measured temperatures of the scene under observation, and color is mapped to temperature through a non-linear relationship that may be changed dynamically depending upon scene content and that exists between temperature and video output.
