Abstract: A mechanical thermal battery initiator for a round where the initiator has a firing pin positioned to strike a primer of a thermal battery upon activation. After installation of the initiator/battery assembly in a round, the end user need not perform any further tasks until firing the munition. At launch, any safety device installed to prevent unintended activation is removed or switched to an active state. When launched, the initiator is subjected to centripetal force and acceleration causing a setback ring to release ball bearings and a spring force from a firing pin spring to push a firing pin into contact with a primer to initiate power on the round.

Abstract: An artifact-suppressing neural network (NN) kernel comprising at least one neural network, implemented in replacement of a DSP, provides comparable or better performance under non-edge conditions, and superior performance under edge conditions, due to the ease of updating the NN kernel training without enlarging its computational footprint or latency to address a new edge condition. In embodiments, the NN kernel can be implemented in a field programmable gate array (FPGA) or application specific integrated circuit (ASIC), which can be configured as a direct DSP replacement. In various embodiments, the NN kernel training can be updated in near real time when a new edge condition is encountered in the field. The NN kernel can include DCC lower layers and dense upper layers. Initial NN kernel training can require fewer examples. Example embodiments include a noise suppression NN kernel and a modem NN kernel.

Abstract: A slot antenna includes a substrate having a first side and a second side, a first conductive layer on the first side of the substrate, and a second conductive layer on the second side of the substrate. A first aperture is in the first conductive layer, a second aperture is in the first conductive layer, a first slotline is in the first conductive layer and in communication with the first aperture, and a second slotline is in the first conductive layer and in communication with the second aperture. A third aperture can be in the second conductive layer. A plurality of vias can be in the substrate and surrounding at least a portion of a region including the first aperture, the second aperture, the first slotline, and the second slotline, each of the vias extending through the substrate from the first conductive layer to the second conductive layer.

Abstract: The system and method of a low inertia, rolling control actuation system (CAS) for a projectile. A CAS having only two canards provides reduced cost and quicker reaction times. In some cases one or more bearings can intermittently decouple the CAS from the projectile and in some cases with the use of a brake. If there are two bearings on either side of the CAS, the front and/or back of the projectile can be decoupled to provide even quicker response times. The front of the projectile may have a warhead and additional sensors or imagers. The rear of the projectile may contain a booster or the like.

Abstract: The fuse mode of a laser guided munition is remotely set and/or changed by encoding fuse mode information onto fuse mode designating light received by the light detector of the munition. Embodiments do not require hardware modification of existing munitions and/or control systems. The mode designating light can be the target designating laser light, and the fuse mode information can be encoded together with counter counter measure (CCM) information. Or the mode designating light source can be a separate laser or non-laser light source. Encoding of the fuse mode information can be by modulation and/or wavelength selection of the mode designating light. In embodiments, the fuse mode can be selected before and/or after launch of the munition.

Abstract: A method and apparatus for performing shearography where the shear length and direction can be set in image processing, thus allowing all shear sizes to be computed and tested from a single data set, which can be collected in a single pass over a test surface or test object. The present process assures that a single data set can be processed with optimal shear length for multiple target types, thus reducing or eliminating the chance of missing a target detection while additionally enhancing target shape analysis by allowing the calculation of target response versus shear length and shear direction.

Abstract: A system for finding up in a projectile flight relative to earth. The system having a transmitter which transmits polarized reference signals to a guidance sub-system on the projectile. The guidance sub-system includes a magnetometer and polarized and non-polarized receivers. Measurements from the magnetometer are used to determine a general up direction. The polarized and non-polarized receivers are arranged such that, during rotation of the projectile, reference signals received by the polarized receiver modulate whereas reference signals received by the non-polarized receivers are unaffected. A ratio of the strengths of the signals received by the polarized and non-polarized receivers determines alignment of a vertical axis. From the general up direction and alignment of the vertical axis, a precise up direction of the projectile in flight relative to the earth can be determined.

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 spectrum 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.
