Abstract: A rocket motor for a gun-fired projectile is configured stiffen the burnable propellant in the rocket motor during burning and/or protect the rocket motor from the pressure that occurs during firing of the projectile from the gun. The rocket motor may include a rigid structure that is integrated into the burnable propellant grain to stabilize the burnable propellant grain during burning of the burnable propellant grain. The rigid structure has a matrix or truss-like shape that extends into the depth of the burnable propellant grain. The rocket motor may include a baffled end cap that covers a nozzle of the rocket motor. The end cap defines a baffled path through the end cap to dampen gas flow into the nozzle and prevent particles of the gun propellant from entering the rocket motor. A rocket motor may implement the rigid structure or the baffled end cap, or both structures.

Abstract: An aft pivot assembly includes a height adjustment mechanism integrated into a device for mounting a payload, to enable release of the payload. The aft pivot assembly releasably secures an aft portion of the payload, such a pod, store, ordinance, or fuel tank. The aft pivot assembly includes a shaft operable with the mount device and a release component, the shaft being rotatable about multiple shaft axes relative to the mount device so as to either minimize or eliminate carriage loads about the aft portion, while reacting jettison loads during a jettison event or phase. The rotation of the shaft about its shaft axes can further be limited via a limit device. As the payload transitions from a carriage phase to a jettison phase, the shaft moves in multiple degrees of freedom and in multiple axes relative to the mount device.

Abstract: A connector is provided and includes one or more radio frequency (RF) signal pins, ground pins arranged in a ring-shape around the one or more RF signal pins, a ground pin supporting mold formed about the ground pins and defining a borehole around the one or more RF signal pins and a dielectric mold formed in the borehole about the one or more RF signal pins and about the ground pin supporting mold.

Abstract: A wafer stack can be produced by using indium electroplating on physical vapor deposition tantalum. The wafer stack includes a substrate, a tantalum-nitride film formed on the substrate, a tantalum layer formed on the tantalum-nitride film, and indium deposited on the tantalum layer. Various relationships of thicknesses between the tantalum layer and the tantalum-nitride film can be used in producing the wafer stack.

Abstract: Systems and methods are provided for point cloud compression. An exemplary method includes: receiving point cloud data; quantizing the point cloud data to remove noise to produce quantized point cloud data; generating, using the quantized point cloud data, a plurality of multi-level tiles; performing reordering within the multi-level tiles to optimize a compression rate producing a plurality of reordered multi-level tiles; bit packing the reordered multi-level tiles minimizing bits required to store per tile header data producing a bit packed multi-level tile data; and performing additional compression on the bit-packed multi-level tile data using a first compression algorithm.

Abstract: A vibration isolator includes a series of hard bushings that press against each other and slide, under the constraint of friction from the engagement of the bushings. A fastener, such as a bolt, passes through the engaged bushings, and one or more springs provide a spring force that maintains the engagement of the bushings. The bushings may include top and bottom bushings having chamfered surfaces, which engage corresponding upper and lower sloped surface on a middle friction bushing which can slide relative to the top and bottom bushings. The isolator may be part of a vibration isolation system that includes multiple isolators to provide isolation for an isolated object. The bushings may be made of metal or another suitable hard material. The isolator may be suitable in particular for vibration isolation in situations where vibrations are of severe, but short duration.

Abstract: A configurable acquisition engine for direct sequence (DS) spread spectrum (SS) is provided that is reconfigurable without increasing memory size for several use cases having different time-frequency uncertainties. The acquisition engine utilizes a frequency-domain decimation filter to reduce the number of output frequency points while still utilizing information from all frequency bins.

Abstract: An electrical device includes an aluminum nitride passivation layer for a mercury cadmium telluride (Hg1-xCdxTe) (MCT) semiconductor layer of the device. The AlN passivation layer may be an un-textured amorphous-to-polycrystalline film that is deposited onto the surface of the MCT in its as-grown state, or overlying the MCT after the MCT surface has been pre-treated or partially passivated, in this way fully passivating the MCT. The AlN passivation layer may have a coefficient of thermal expansion (CTE) that closely matches the CTE of the MCT layer, thereby reducing strain at an interface to the MCT. The AlN passivation layer may be formed with a neutral inherent (residual) stress, provide mechanical rigidity, and chemical resistance to protect the MCT.

Abstract: An arbor press includes a limiter for limiting load and/or travel of a ram used to press on an object. The ram includes a pair of pieces, a shaft and a sleeve, which are capable of relative translation, modulated by the spring. The spring may be preloaded, and configured to prevent overloading of the object, by limiting the transmission of force through the ram. The ram may also be configured to limit travel of the ram. The arbor press may include gearing to translate rotational movement of a handle to translational movement of the ram. The gearing may include a rack that is part of or is coupled to the shaft, and a pinion that is connected to the handle. Parts of the arbor press may be enclosed in a housing, to contain debris from metal-to-metal sliding in the arbor press, facilitating use in clean rooms.

Abstract: A method for node cluster assignment in a graph includes identifying neighboring nodes of a first node in the graph, calculating one or more elements of a graph Laplacian of the graph, the one or more elements of the graph Laplacian corresponding to the first node and the neighboring nodes, initializing a first wavefunction associated with the first node with an initial value, evolving the first wavefunction associated with the first node over time based on the initial value, the one or more elements of the graph Laplacian, and previous states of wavefunctions of the neighboring nodes to generate a time-evolved wavefunction vector, and identifying a cluster assignment of the first node based on the time-evolved wavefunction vector.
