Abstract: A passive vector modulator (PVM) includes a divider that splits an input signal into a first divided signal and a second divided signal 90° apart in phase. The PVM includes a switched transformer phase shifter including primary windings to form first primary windings and second primary windings receiving the first divided signal and the second divided signal respectively. First secondary windings are coupled to the first primary windings, the first secondary windings being center-tapped and outputting first and second phase shifted output signals, phase shifted 180° and 0° respectively. Second secondary windings are coupled to the second primary windings, the second secondary windings being center-tapped and outputting third and fourth phase shifted signals, phase shifted 270° and 90° respectively. The PVM includes a switch configured to receive the phase shifted output signals. The switch selectively outputs one of the phase shifted output signals, or a combination, from the PVM.

Abstract: A drive mechanism for actuating a control surface of a vehicle that moves through a fluid medium. The mechanism directly translates the rotational motion provided by an input drive to a control surface that is used to direct the vehicle. The mechanism provides both weight and space savings as well as limits, if not eliminates, backlash. The angled drive mechanism may be particularly suited for use in applications such as UAV/UUV, munitions, and other relatively small platforms.

Abstract: Techniques are described for a computing device to estimate pulse parameters. A method includes (a) receiving a digitized radio frequency (RF) signal as a digital input signal; (b) feeding the digital input signal into a plurality of input nodes of a trained Pulse Parameter Estimation Neural Network (PPENN), the PPENN having been trained using machine learning; (c) operating the trained PPENN to estimate a plurality of pulse parameters of a set of pulses embedded within a waveform of the digital input signal and to output the plurality of pulse parameters from the trained PPENN; and (d) processing the plurality of pulse parameters to further quantify the set of pulses. A system, apparatus, and computer program product for performing this method and similar methods are also described.

Abstract: An apparatus includes a current-based temperature compensation circuit having a reference buffer, a biasing current mirror, and a controller. The reference buffer is configured to receive a biasing reference voltage at a voltage input terminal and replicate the biasing reference voltage to first and second buffer terminals. At least one of the first and second buffer terminals is configured to be electrically connected to at least one gate terminal of an analog complementary metal oxide semiconductor (CMOS) physically unclonable function (PUF) cell. The biasing current mirror is configured to receive a reference current at a current input terminal and replicate the reference current to the first buffer terminal. The controller is configured to compensate an output of the CMOS PUF cell for temperature variation based on a weighted sum of a bandgap current, a current proportional to absolute temperature, and a current complementary to absolute temperature.

Abstract: A method of encoding information in an object that may allow for enhanced tailorability of the encoding during the processing and/or also enhance the amount of information encoded in the object. More particularly, the method of encoding the object enables the magnetic characteristics at different spatial locations of the object to be modified to form a spatial array of the different magnetic characteristics for representing the encoded information. The method can be used to permanently embed a magnetic signature in a non-magnetic object, for example. More specifically, the method allows different portions of the object to exhibit different magnetic characteristics at each spatial location of the object in three dimensions, and more particularly configuring the magnetic vectors of those portions in many possible orientations with a 4n steradian solid angle and/or with different intensities.

Abstract: An oscillating heat pipe that can maintain efficient heat transfer even in a high gravity force equivalent environment is provided. The heat pipe can comprise a condenser region having a first plurality of bends, an evaporator region having a second plurality of bends, and a plurality of intermediate portions. The plurality of intermediate portions can extend between the first plurality of bends and the second plurality of bends. The plurality of intermediate portions can include a first intermediate portion and a second intermediate portion. A cross-sectional area of the first intermediate portion can be larger than a cross-sectional area of the second intermediate portion in a plane at a first distance from the evaporator region. The cross-sectional area of at least one of the first or second intermediate portions can increase from the condenser region towards the evaporator region.

Abstract: A highly adaptive seal for use in advanced aircraft propulsion and missile systems is provided. The seal is capable of effectively limiting invasive thermal energy and corrosive airflow from entering the internal systems and hardware of the aircraft by managing and controlling the incoming air flow. The seal is configured to be disposed between component parts of the aircraft and create a tortuous path for air flow. The seal maintains contact with the component parts between which it seals by allowing for significant radial and axial displacement freedom of the component parts. Accordingly, hot gas intrusion may be limited in a wide variety of dynamic environments and component displacement conditions. Limiting such hot gas intrusion has a substantial impact on component survivability over the course of free flight of an aircraft.

Abstract: A camera assembly includes a housing inside of which components are maintained at a cryogenic temperature. The components maintained at cryogenic temperature include a detector that is mounted on an integrated circuit, which in turn is mounted on a platform, such as a ceramic platform, which includes electrical connections for the integrated circuit. The camera assembly also includes one or more subplatforms, maintained above the cryogenic temperature, such as ambient temperature, that receive electrical inputs from outside the housing, and make electrical connections to the platform. The connections may be made from the one or more subplatforms, through openings in the platform and/or outside one or more outer edges of the platform. The assembly may include covers of exposed parts of the one or more subplatforms, to facilitate thermal isolation between the interior of the assembly (at cryogenic temperature) and the one or more subplatforms (above cryogenic temperature).

Abstract: A system and method is provided that captures command and control string data during an unmanned vehicle operation. The control string includes user inputs (e.g., mouse inputs, keyboard inputs, etc.) and display outputs (i.e., data displaying to the user via displays). The control string data is captured and stored during the sortie (i.e., a flight) and the control string is preserved (also referred to as impounded) when a mishap occurred during the sortie.
