    Abstract: A flip-flop and latch circuit is disclosed. The circuit includes a single-input inverter, a dual-input inverter, a single-input tri-state inverter, a dual-input tri-state inverter, and two single-event transient (SET) filters. The single-input tri-state inverter receives an input signal D. The dual-input tri-state inverter includes a first input, a second input and an output, wherein the first input receives output signals from the dual-input inverter and the second input receives output signals from the dual-input inverter via the first SET filter. The output of the dual-input tri-state inverter sends output signals to a first input of the dual-input inverter and a second input of the dual-input inverter via the second SET filter. The single-input inverter receives inputs from the dual-input inverter to provide an output signal Q for the circuit

    Abstract: Systems and methods for generating infrared radiation are provided. The systems and methods may generate, via one or more pump sources, one or more pump beams. The one or more pump beams may define a single beamline. The systems and methods may further generate, via a nonlinear optical converter, a first signal wavelength, a first idler wavelength, a second signal wavelength, and a second idler wavelength based, at least in part, on the one or more pump beams. The first signal wavelength and the first idler wavelength may be independently variable from the second signal wavelength and the second idler wavelength. The systems and methods may further output, via the nonlinear optical converter, a mid-wave infrared (MWIR) beam including three or more wavelengths in the single beamline.

    Abstract: Techniques are disclosed for determining the presence of pulse jams in an identification friend or foe (IFF) system. In an embodiment, a plurality of jamming pulse rates are determined. Each of the plurality of jamming pulse rates is a count of jamming pulses entering the IFF system during a corresponding integration period. Each of the plurality of jamming pulse rates is a count of jamming pulses associated with non-valid signals entering the IFF system. An average jamming pulse rate is computed based on the plurality of jamming pulse rates. The average jamming pulse rate is then compared against a pulse jam threshold to determine whether a pulse jam is present (or not present) in the IFF system.

    Abstract: The system and method of swarm navigation using a follow the forward approach. Using on-board sensors and communications links between members of a swarm, numerous targets can be engaged more quickly and precisely. In some cases, a designator is used to help a forward of the swarm navigate to a target using image-based navigation up until terminal guidance is used. A cascade of messages are projected back to a following round so that, each member of a swarm can determine a best target/round match and provide real-time, up-to-date information regarding targets' locations and each round's location, range to target, target selection, and the like.

    Abstract: The system and method for an additively manufactured self-destructive delay device is a bellow/lattice structure or other form. The device may be installed as a replacement to a previous device, where the device yields under the deployment force at a specific rate to match the time-displacement curve established by a previous hydraulic delay device. The delay device has a virtually unlimited lifespan, is cheap to manufacture, and can be adaptable to other loads and conditions for use in or on other platforms. This solution can be applied anywhere where mechanical delay devices are needed within systems. Some examples include wing/fin deployment mechanisms, safety crumple zones, or devices that act as shear pins.

    Abstract: A method, system, and computer program are described for identifying the presence of narrowband signals within a wide instantaneous bandwidth by exploiting the spatial diversity of the received signals using an array aperture to provide detection capability. For example, the method includes receiving and channelizing digitized signals into signals with a narrow bandwidth of interest. The method further includes estimating covariance matrices associated with the signals, determining a set of Eigenvalues for the covariance matrices, and analyzing each Eigenvalue to determine a rank change estimate. The method further includes identifying one or more of the signals that have a positive rank change estimate, computing a beam forming weight and direction estimate for each signal that has a positive rank change estimate, and outputting an indication of the signals that have a positive rank change estimate including one or more of fine timing information, the beamforming weights, and the direction estimate.
