Abstract: Techniques and architecture are disclosed for a system that includes a fuze at a leading end of a projectile body and a fuze setter configured to engage the fuze and to program the same prior to launch. The system, in one example, includes a plurality of electrical contact pads on an exterior surface of a fuze radome housing and a plurality of electrical contact pins on the fuze setter. The electrical contact pads are arranged in a rotationally symmetric pattern that enables an electrical interface to be formed with the electrical contact pins, regardless of the rotational orientation of the fuze. Commutation is performed to rotate signals to the electrical contact pins instead of requiring that the fuze be physically rotated to bring the electrical contact pads into alignment with the electrical contact pins.

Abstract: The system and method for a low profile high gain dual polarization UHF/VHF antenna. In some cases a spiral antenna over a small cavity, with arms attached on either side is provided. The antenna structure is a short distance above a ground plane (e.g., less than 1/10 wavelength at the high frequency of operation). The arms are terminated to ground and the values of the terminations can vary depending on installation and the value chosen for the spiral termination. In some cases, the spiral antenna is not limited to a two arm spiral only as any type of spiral antenna may be used.

The 3D-printer build file is utilized to print the integrated heat pipe on a 3D printer.

Abstract: A pressure relief valve having two rigid sealing surfaces lapped to a smoothness Ra of 8 micro-inches or less, and flatness within 80 micro-inches, forms a reliable seal by direct contact therebetween without an elastomer. The sealing surfaces and surrounding structures can be made of one or more metals, such as alloys of stainless steel, and can be CTE-matched, so that the valve is not impeded by environmental temperature changes. In a disclosed embodiment, a “poppet” is axially pressed against a seal plate by a spring. The poppet can be axially stabilized by sliding within a surrounding cylinder or spacer, and can contact the surrounding surface with a plurality of “arms” that reduce friction and enable gas flow therebetween. The poppet can be made from anti-galling Nitronic 60 alloy, and the surrounding structures can be stainless steel. Embodiments are suitable for low-pressure gas applications in extreme environments.

Abstract: The system and method of dynamic weapon to target assignment (DWTA) using a control based methodology to dynamically assign each projectile to a target in a multiple target engagement situation. In some cases, closest proximity is used in a real-time, to accomplish the DWTA functional requirement and performance criteria. In some cases, g pulling acceleration and projectile fin deflection motion are also used to assess the best matched pair for each projectile and each target with an end goal of intercepting the target or guiding the projectile to an acceptable error basket for target destruction via detonation. For the closest distance criterion for projectile/target pairing, a cutoff time is used to ensure the pairing is conducted within an acceptable duration while still being able to intercept the target or meet a required miss distance basket (e.g., <3 m).

Abstract: A system produces an interpolated luminance-balanced monochrome image from a Red-Clear-Clear-Clear (RCCC) pattern image. It may include an imager having a RCCC pattern filter array. There is an interpolation processing module with one or more processors processing sampled, red filtered image pixels. A red plane is interpolated using the sampled, red filtered pixels, producing an interpolated red for the pixels. The interpolated red pixels are subtracted from the sampled clear pixels, producing a “Clear minus Red” (“C?R”) plane. A C?R value is interpolated for the red filtered pixels. The interpolated C?R value is added to the sampled red pixels, and the monochrome image is output, where the luminance is balanced across the pixels, especially in low and very light environments.

A first igniter laser is used at short pulse widths and a second heater laser is used at longer pulse widths.

Abstract: A disclosed apparatus and method reduce the likelihood of multiple bit single event upset (SEU) errors in space-deployed memory devices and memory macros, without requiring novel, specialized memory designs and without significant added cost or performance loss. For each memory, a bit selection layer effectively increases the mux of the memory bit table, thereby reducing the word size while increasing the word capacity, without changing the total memory capacity. As a result, the separation between the physical bit storage locations for each word is increased, thereby reducing the likelihood of multiple bit SEU errors. A buffer can be implemented if the memory lacks individual bit write control. The memory can be implemented in a core IC of an MCM-HIC, and the bit selection layer and/or buffer can be implemented in a chiplet or chiplets of the MCM-HIC.

Abstract: A computing network data layer architecture or system includes an open data layer module comprising a translation layer. Translation flags are within the translation layer and each flag is associated with a database language of an underlying database that can be coupled architecture or system.
