Abstract: An apparatus includes a photonic integrated circuit having an optical phased array. The optical phased array includes multiple unit cells, where each unit cell includes an antenna element configured to transmit or receive optical signals. The unit cells are grouped into multiple supercells, and each supercell includes multiple unit cells. The apparatus also includes multiple arms configured to modify the optical signals transmitted or received by the optical phased array. Different ones of the arms are controllable to support transmission or reception of different optical signals in different directions.

Abstract: An apparatus includes an auto-alignment laser configured to generate an auto-alignment laser beam. The apparatus also includes a spectral beam combiner having a diffraction grating. The diffraction grating is configured to diffract multiple input laser beams to produce a combined beam having a higher power or energy compared to the individual input laser beams. The diffraction grating is also configured to diffract the auto-alignment laser beam so that a portion of the auto-alignment laser beam co-propagates in a common direction with the combined beam. Wavelengths of the input laser beams and the auto-alignment laser beam may be selected such that portions of the input laser beams and the portion of the auto-alignment laser beam diffract from the diffraction grating in the common direction. The portion of the auto-alignment laser beam that co-propagates with the combined beam may include a higher-order diffraction of the auto-alignment laser beam from the diffraction grating.

Abstract: A mechanism secures and then deploys a rotationally coupled rigid member to and from a frame. One end of a curved member is pinned to the rigid member and the other end is on or in a reaction guiding element. In a closed state, the curved member is straightened from its originally manufactured or “free state” curvature and the other end is secured to the frame via a latch mechanism. The tension in the straightened curved member serves to preload the rigid member against the frame. To move to an open state, the latch mechanism is released allowing the other end of the curved member to move with or within the reaction guiding element along a constrained path towards its free state curvature. The curved member reacts against the frame, the pinned end in the rigid member and the reaction guiding element to rotate the rigid member away from the frame.

Abstract: Apparatus and associated methods relate to automatically loading a plurality of hazardous entities into a hazardous-entity container. Such automatic loading is performed by: i) lifting a selected hazardous entity of a plurality of hazardous entities from a stowed position to an elevation of a corresponding hazardous-entity portal of the hazardous-entity container; ii) sensing relative alignment the selected hazardous entity with respect to the corresponding hazardous-entity portal iii) aligning the selected hazardous entity with the corresponding hazardous-entity portal based on the relative alignment sensed by the alignment sensor; iv) evaluating whether an insertion condition is met based at least in part on the relative alignment sensed by the alignment sensor; and v) inserting the selected hazardous entity into its corresponding hazardous-entity portal if the insertion condition is met.

Abstract: Vibration compensation is provided for Interferometric Noise Suppressed Oscillators (INSOs). In an INSO the error signal at the mixer output responds linearly to changes in carrier frequency. A vibration compensation signal is summed with the error signal at the input to the feedback amplifier to provide the control signal to the loop phase shifter to suppress close-in phase noise near the carrier frequency and to reduce the effects of mechanical vibrations on oscillator phase noise. The addition of the vibration compensation signal does degrade carrier suppression, hence increases the flicker noise contributed by the INSO's LNA but does so without degrading overall oscillator phase noise. In a frequency tuned configuration, the vibration compensation signal reduces the effects of mechanical vibrations on oscillator phase noise independent of the tuning voltage applied to the phase shifter.

Abstract: An electrical interconnect including slotted lug with a receiving end for connecting to a flat electrical conductor and a fastening end for connecting to a surface mount terminal extending from the surface of a circuit, such as an integrated metal substrate (IMS) circuit board or a circuit card assembly. The interconnect provides a secure connection capable of transmitting a current of at least 100 Arms, to give a non-limiting example value. The interconnect further provides low contact resistance and ease of manufacturing.

Abstract: An apparatus includes a Dewar having an endcap. The apparatus also includes a heat sink and a thermal interface material configured to thermally couple the endcap of the Dewar to the heat sink. The thermal interface material includes an amorphous pliable material that is configured to transfer thermal energy between the endcap of the Dewar and the heat sink without structurally coupling the Dewar to the heat sink. A thermal shoe may be positioned between the thermal interface material and the heat sink, and the thermal shoe may be configured to hold the thermal interface material against the endcap. The thermal shoe may have (i) a smaller cross-sectional size in a portion of the thermal shoe contacting the thermal interface material and (ii) a larger cross-sectional size in a portion of the thermal shoe contacting the heat sink.

Abstract: A system includes a first dataset of vehicle trajectories including individual vehicle tracks forming a first track density, a desired vehicle track density profile, a spatio-temporal coverage metric, and a track model including Heaviside functions encoding track time origins and durations for the individual vehicle tracks and including locations for the plurality of individual vehicle tracks. Approximations of the Heaviside functions are minimized as a function of the spatio-temporal coverage metric. The first dataset of vehicle trajectories is manipulated to satisfy the desired vehicle track density profile through minimizing an approximation of the Heaviside functions. Each individual vehicle track in the first dataset of vehicle trajectories is shifted as a result of the optimization, thereby generating a second dataset of vehicle trajectories having a second track density.

Abstract: A system and method of tracking a hypersonic object over a flightpath includes at least one observer having at least one sensor. The sensor is configured to provide measurements of the hypersonic object that are geometrically diverse such that each observer may independently measure any combination of range, angles, Doppler, and angle rates. The observers transmit measurements to a processing unit as the hypersonic object undergoes three phases including a boost phase, a ballistic phase, and a hypersonic glide phase. The hypersonic object is tracked over many time steps by first selecting a dynamics model representative of expected object kinematics during said phase. Then, an unscented Kalman filter is used to predict a future state and a covariance using the dynamics model that was selected. Finally, the unscented Kalman filter updates the future state and covariance that were predicted based on the geometrically diverse measurements of the sensors.

Abstract: A method includes transmitting a first electromagnetic signal from a first node to a second node and receiving a second electromagnetic signal from the second node at the first node. The method also includes repeating the transmission of the first electromagnetic signal and the reception of the second electromagnetic signal multiple times. The method further includes identifying, based on the repeated transmissions and receptions, a time-of-flight associated with a travel time for one of the electromagnetic signals to travel between the first and second nodes. The time-of-flight is indicative of a distance between the nodes.
