EXPLOSIVE FIRING TRAIN WITH A SINGLE EXPLOSIVE TRANSFER INTERFACE
An EFI or LEEFI provides enhanced detonation energy sufficient to directly detonate a main charge to improve the reliability and ease the qualification of an explosive firing train. This is accomplished by forming the EFI's output charge from an explosive material typically used as a booster explosive (e.g., PBXN-5, CH-6 and Composition A5) rather than a primary explosive and making the diameter of the output charge greater than the diameter of the barrel thus increasing the total mass of the output charge. The explosive firing train now requires only a single explosive transfer interface. For use in military grade munitions, the EFI's casing is formed with one or more vent holes radially adjacent the output charge.

SYSTEM AND METHOD FOR BEHAVIORAL EMITTER IDENTIFICATION, EMISSION TRACKING, AND ANOMOLY DETECTION
A system and method are described for emitter identification, emission tracking, and anomaly detection in an electronic warfare (EW) environment. Association results are obtained of waveforms of the emitters in a current dwell. The association results include a current distribution of inferred groupings of the waveforms. Features are generated for each waveform by comparing the current distribution and recent emitter historical behavior contained in a Dynamic Emitter Library (DEL). A probability of association with a track is determined for each waveform based on the features generated through the comparison. An identity of an emitter based on the probability and anomalous behavior of the emitter are inferred for each waveform.
A system and method are described for emitter identification and tracking in an electronic warfare (EW) environment. The system includes an antenna array configured to receive signals from radio frequency (RF) emitters during a dwell. Processing circuitry converts the received signals into digital signals. Pulses are detected and characteristics of the pulses determined to form pulse descriptor words (PDWs). The PDWs obtained during the dwell are deinterleaved using unsupervised machine learning to form clusters. The clusters are categorized using one or more supervised machine learning algorithms to determine whether the PDWs correspond to known or unknown emitters and the results tracked as in or out of library emitters. After merging the in or out of library emitters, an emitter report is generated and used to update a library of emitter profiles used by the supervised machine learning algorithms as well as determine countermeasures to generate.
A system and method are described for updating Machine Learning (ML) models in an electronic warfare (EW) environment. The ML models are updated automatically post mission using threat data of emitters in the EW environment and then deployed to hardware in an aircraft. The updated ML models are used during a subsequent mission and include an unsupervised ML model to deinterleave waveforms received from the emitters and a supervised ML model for emitter identification, waveform tracking, and anomaly detection based on the deinterleaved waveforms. The ML models are updated by augmenting templates that indicate the behavior of the emitters and training the ML models using many plausible superpositions of the augmented templates. The ML models are updated by selecting and applying non-linear augmentations of at least one of the templates and new templates randomly using a Monte Carlo approach.

The FTC is configured to be carried through the first hole in the outer surface of the target by the flow of water therethrough for detonation on the other side of the outer surface of the target, perhaps forming a second hole in an inner surface of the target.

INTELLIGENT NETWORK OF WEARABLE MAGNETIC TX/RX TAGS FOR AUTONOMOUS LOCAL AND GLOBAL MONITORING AND RESUPPLY OF CONSUMABLE RESOURCES IN MOBILE UNITS
A system for autonomously managing resupply of consumable resources for a mobile unit includes sensors that monitor a level of a consumable resource for each entity in the unit. A network of tags communicates via short-range magnetic communications links. A local node provides a long-range RF communication link to communicate with a global node. Together the network of tags, local node and global node initiate a local resupply of the consumable resource to one or more entities from other entities within the mobile unit and a global resupply of the mobile unit from the one or more depots. The network of sensors/tags automates the task of monitoring resource levels and managing resupply. The use of the magnetic portion of the EM spectrum for local communications within the mobile unit overcomes the issues associated with RF in harsh or hostile environments.

A dual-bearing assembly (602; 902; 1002; 1102) includes an annular cantilever beam spring (300; 500; 520; 600; 900; 1000; 1100) positioned in-line and either internal or external to a pair of bearings (604, 606; 904, 906; 1004, 1006; 1104, 1106). The spring includes first and second sets of N stand-offs (312; 502; 522) evenly positioned around opposing top and bottom surfaces (304, 306) of a flat annular beam at 360/N degree intervals and angularly offset with respect to each other by 360/2N degrees such that each said stand-off is evenly spaced between adjacent pairs of stand-offs on the opposing surface. A pre-load mechanism (616; 916; 1016; 1116) is configured to apply opposing axial loads to the stand-offs to deflect the flat annular beam axially at each stand-off in opposing directions to induce a curvature to the annular beam and store energy in the beam to form load paths through the spring and rolling elements (618; 918; 1018; 1118) to pre-load the dual-bearing assembly. The dual-bearing assembly may be configured as DB, DF, universal or tandem. The spring stiffness is determined by the elastic material properties of the flat annular beam, not the initial geometry as is common with the COTS springs.

ANNULAR CANTILEVER BEAM SPRING AND PRE-LOADED ASSEMBLY
An annular cantilever beam spring (300; 500, 520; 600; 800; 900) is capable of exhibiting low friction and hysteresis and stiffness and specifically stiffness/volume far exceeding currently available COTS springs. The spring includes first and second sets of N stand-offs (312; 502; 522) evenly positioned around opposing top and bottom surfaces (304, 306) of a flat annular beam at 360/N degree intervals and angularly offset with respect to each other by 360/2N degrees such that each said stand-off is evenly spaced between adjacent pairs of stand-offs on the opposing surface. The first and second sets of standoffs are responsive to opposing axial loads to deflect the flat annular beam axially at each stand-off in opposing directions to induce a curvature to the annular beam and store energy in the beam. The spring stiffness is determined by the elastic material properties of the flat annular beam, not the initial geometry as is common with the COTS springs.

DEBLURRING MOTION-BLURRED IMAGES USING MAP ESTIMATE AND ADAPTIVE PRIORS
A method of deblurring an image taken by a moving imaging sensor. The method includes: receiving an image from the imaging sensor; collecting motion data indicative of motion of the sensor while capturing the image; applying successive approximations in deblurring based on certain features of the image; and applying a Maximum A Posteriori (MAP) deblurring process with adaptive priors to deblur the image and create a deblurred image, wherein the MAP deblurring process applies a first prior in certain regions and second prior in other regions.
A base isolator for vibration isolation mounting of equipment, includes a pair of rigid (or relatively rigid) tubes, a flexible tube with slots between beams, and a pair of slitted plates. The rigid tubes and the flexible tube may be concentric. The slitted plates couple together ends of the tubes and provide vertical (axial) translational compliance. The flexible tube, which is outside or within the rigid tubes, provides horizontal translational compliance in directions perpendicular to an axis of the isolator. The base isolator, while providing compliance in all three translational directions, provides rotational stiffness, such as for rotational torques about the axis, and more generally for pitch and roll directions.
