Abstract: An energy harvesting system is disclosed that is especially well-suited for use on aerodynamic systems such as guided projectiles or other aerobodies. A series of piezoelectric cantilevers are arranged to capture vibrations from the ambient environment and transduce the mechanical motion from the vibrations into useful electrical energy. The piezoelectric cantilevers can be arranged along different planes from one another to capture different vibrational modes and directions. A power conditioning circuit is included to receive the electrical energy produced by the piezoelectric cantilevers. A storage element coupled to the power conditioning circuit is configured to store charge based on the electrical energy produced by the plurality of piezoelectric cantilever structures. The stored charge can be used to provide low levels of power to certain electrical components on board the aerodynamic system before it has been launched.

Abstract: The system and method of mixing pitch and roll commands from a flight control computer to produce fin deflections applied to as few as two fins to simultaneously produce both a rolling moment and a pitching moment. The system may be mechanical or digital where actuators can be linear or rotary, digital or analog. Deflections of the fins are generated which produce pitch and roll moments where addition of pitch and roll commands determines deflection commands to be sent to a first fin and subtraction of pitch and roll commands determines deflection commands to be sent to a second fin.

Abstract: The system and method of a steering a moving object using a control plate-based control actuation system on the moving object. The control plate-based control actuation system having a control plate with at least four fin linkages for connecting at least four fins to the control plate; and three actuators configured to move the control plate to produce movement in two or more of the at least four fins. The system produces roll, pitch, and yaw moments for the moving object using three actuators acting on the control plate and thus moving two or more of the at least four fins all with no loss of performance as compared to systems with four actuators.

Abstract: The system and method of producing a first path comprising a pulse stretcher for a mid-wave infrared (MWIR) signal, an optical parametric chirped-pulse amplification (OPCPA) amplifier, and a MWIR compressor for producing a first beam in a MWIR portion of the spectmm and a second path comprising a pulse stretcher for a long wave infrared (LWIR) signal, an OPCPA amplifier, and a LWIR compressor for producing a second beam in a LWIR portion of the spectrum. Each beam, on its own, is configured to produce laser-matter interactions at long range (100s of meters), having nonlinear effects and favoring supercontinuum generation spanning multiple octaves, that is temporally and spatially overlapped with the fundamental laser beam.

Abstract: A platform with an auto-router takes into account non-navigation data, such as IR image sensor data or other non-navigation data to develop a route for a platform. The non-navigation data may be obtained from existing non-navigation sensors carried by the platform. The non-navigation data is fed to an auto-router that takes into account the non-navigation data to generate or dynamically alter a route for the platform.

Abstract: A co-boresight refractive beam director for a full duplex laser communication terminal includes a chromatic beam steering element, such as a two or three prism Risley prism assembly, and a dispersion compensation mechanism (DCM) inserted in either the transmit or receive path. The DCM adjusts a beam direction of either the transmit or receive laser beam to compensate for a pointing difference introduced by the beam steering element due to a difference between the transmit and receive wavelengths. The DCM can include a tip/tilt mirror and actuator, which can be a commercially available FSM assembly. The beam steering element can be temperature stabilized. Position feedback sensors can increase DCM speed and accuracy. The pointing difference can be calculated and/or interpolated from a pre-established look-up table or fitted curve relating pointing differences to transmit and receive frequencies and the pointing direction of the beam steering element.

Abstract: Techniques, a system, and architecture are disclosed for top side transistor heat dissipation. The heat dissipation is done through single crystal epitaxially grown layer such as AIN. The architecture may include a back side heat sink to increase thermal dissipation as well. The architecture may further include a pseudomorphic channel layer that is lattice matched to the substrate.

Abstract: A multiport splitter with a circuit that is less costly, smaller, impedance matched on all ports, provides 9.54 dB isolation between neighboring ports, and is balanced as compared to the current typical implementations. The present disclosure may further provide a single multiport splitter that may be increased to any suitable number of output ports without the need for cascading multiple splitters and/or couplers together in a single device.

Abstract: A sequencer for use with a countermeasure defense system includes an input signal indicative of firing an expendable, a circuit card that receives the input signal indicative of firing the expendable and an output analog signal from the circuit card that fires the expendable. The parameters of the output analog signal correspond to parameters of a digital waveform.

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.
