Abstract: An active mode image sensor for optical non-uniformity correction (NUC) of an active mode sensor uses a Micro-Electro-Mechanical System (MEMS) Micro-Mirror Array (MMA) having tilt, tip and piston mirror actuation to form and scan a laser spot that simultaneously performs the NUC and illuminates the scene so that the laser illumination is inversely proportional to the response of the imager at the scan position. The MEMS MMA also supports forming and scanning multiple laser spots to simultaneously interrogate the scene at the same or different wavelengths. The piston function can also be used to provide wavefront correction. The MEMS MMA may be configured to generate a plurality of fixed laser spots to perform an instantaneous NUC.

Abstract: A system detects a maneuver of at least one space object by receiving a first data set relating to orbital characteristics of at least one space debris object. The system trains a model, using the first data set, in order to model orbital behaviors of the at least one space debris object. The system then receives a second data set relating to orbital characteristics of the at least one space object, and detects a maneuver of the at least one space object using the trained model and the second data set.

Abstract: A spring-loaded ball valve includes a spring, a first pin, a second pin, and a handle. The spring is configured to apply pressure to the first pin and second pin when the ball valve is in both the fully open and fully closed positions. The spring applies maximum torque when the ball valve is in the fully open or fully closed position to ensure the valve remains in the fully open or fully closed position.

Abstract: A device includes a photonic integrated circuit having an optical phased array. The optical phased array includes multiple array elements, where each array element includes (i) an antenna element configured to transmit or receive optical signals and (ii) a phase modulator configured to phase-shift the optical signals transmitted or received by the antenna element. The device also includes multiple digital register in integrated circuit (DRIIC) cells, where each DRIIC cell is associated with one of the array elements. The DRIIC cells are configured to receive digital inputs and to provide outputs to the phase modulators of the associated array elements in order to control the phase-shifts of the optical signals transmitted or received by the antenna elements based on the digital inputs.

Abstract: A propulsion system includes multiple solid rocket motors that are activated by a single initiator. The rocket motors act in parallel, providing thrust in a single direction. The initiator activates an ignition charge that is in or operatively coupled to a non-annular plenum that transports hot gasses from the ignition charge to the rockets to be ignited. The plenum may be an unchoked plenum, allowing flow of hot gasses without choking. The plenum may be lined with an insulator material. A cover may be used to cover the plenum, and also to receive the rocket motors. The rocket motors may be solid-fuel rocket motors, with propellant grains and nozzles. The individual rocket motors may have separate ignition booster charges coupled to the plenum, which are ignited by the ignition charge and which in turn ignite the propellant grains.

Abstract: An example system includes a dynamo-electric machine. The dynamo-electric machine includes a rotor that is cylindrical and that is configured for rotation and a stator that is arranged relative to the rotor. The stator has a stepped configuration that defines a first diameter for the stator and a second diameter for the stator. The first diameter is greater than the second diameter. Zones of the stator at the first diameter hold direct-axis (D-axis) windings and zones of the stator at the second diameter hold quadrature axis (Q-axis) windings. An airgap between the rotor and the Q-axis windings is greater than an airgap between the rotor and the D-axis windings.

Abstract: A system includes a planar waveguide that includes an active gain medium configured to receive pump light from a pump source and amplify stimulated emission light. The planar waveguide has a fast axis and a slow axis and is configured to operate in single mode in the fast axis and multimode in the slow axis. The system also includes a hybrid spatial filter configured to receive the amplified stimulated emission light from the planar waveguide and output laser light. The hybrid spatial filter includes a physical slit having a narrower dimension corresponding to the slow axis of the planar waveguide. The physical slit is configured to reduce an intensity of the amplified stimulated emission light received from the planar waveguide. The hybrid spatial filter also includes a Volume Bragg Grating (VBG) configured to constrain an angle of the amplified stimulated emission light and enable compact geometry intra-cavity beam expanding/collimating optics.

Abstract: Backpropagation of an artificial neural network can be triggered or based on input data. The input data are received into the artificial neural network, and the input data are forward propagated through the artificial neural network, which generates output values at classifier layer perceptrons of the network. Classifier layer perceptrons that have the largest output values after the input data have been forward propagated through the artificial neural network are identified. The output difference between the classifier layer perceptrons that have the largest output values is determined. It is then determined whether the output difference transgresses a threshold, and if the output difference does not transgress a threshold, the artificial neural network is backpropagated.

Abstract: A beam splitter configured to split incident light includes a polarization grating having a liquid crystal layer and a reflective sub-aperture beam splitter. The liquid crystal layer is configured to switch between an “on” state and an “off” state in response to an applied voltage. In the “off” state, the polarization grating angularly deviates and polarizes a portion of received incident light passing therethrough. In the “on” state, crystals of the polarization grating align with the incident light, allowing it to pass therethrough unimpeded and unpolarized. The beam splitter includes a plurality of sub-aperture mirrors which are spaced at randomly varying distances from one another, the mirrors being configured to reflect a portion of the incident light.

Abstract: A conductive interconnect structure comprises a polymeric substrate (e.g., a thermoplastic) and a plurality of compliant conductive microstructures (e.g., conductive carbon nanofibers) embedded in the polymeric substrate. The microstructures can be arranged linearly or in a grid pattern. In response to heating, the polymeric substrate transitions from an unshrunk state to a shrunken state to move the microstructures closer together, thereby increasing an interconnect density of the compliant conductive microstructures. Thus, the gap or pitch between adjacent microstructures is reduced in response to heat-induced shrinkage of the polymeric substrate to generate finely-pitched microstructures that are densely pitched, thereby increasing the current-carrying capacity of the microstructures. The polymeric material can be heated to conform or form-fit to planar and non-planar surfaces/geometries, and can be selectively heated at various portions to tailor or customize the interconnect density of the microstructures at selected portions. Associated electrical conducting assemblies and methods are provided.
