Abstract: An insulated blast tube includes an insulating layer of a burn resistant material such as phenolic resin formed on an interior surface of the blast tube to provide the necessary erosion and thermal insulation properties to protect the blast tube and a heavy inert gas insulated layer formed in the walls of the blast tube itself to provide the additional thermal insulation properties to protect any non-propulsive sub-systems positioned in the void space around the blast tube. A void space in the walls of the blast tube contains an inert gas such as Argon, Krypton, Xenon or a synthetic inert gas having a density of at least 1.5 kg/m3 and a thermal conductivity Tcond_gas of no greater than two-thirds the thermal conductivity of air Tcond_air to form the heavy inert gas insulation layer.

Abstract: Embodiments regard techniques for mitigating radio frequency interference (RFI) in weather data. A method includes receiving raw pulse returns, censoring the raw pulse returns to alter data of the raw pulse returns that is affected by the RFI resulting in censored pulse returns, compressing the censored pulse returns resulting in censored, compressed pulse returns, and transmitting, by an antenna, the censored, compressed pulse returns.

Abstract: Embodiments regard improving machine learning (ML) training dataset generation. A method includes receiving or generating, by a scene editor, an image, augmenting, using procedural generation, the image to include a three-dimensional (3D) model of an object resulting in a synthetic image, and generating, by a generative model and based on the synthetic image, a realistic image.

Abstract: A method is provided for assembling an apparatus. During this method, a circuit element is arranged with a circuit board. The circuit element includes an element aperture. The circuit board includes a board aperture. A plunger is moved in a first direction to pass a distal end of the plunger through the element aperture and the board aperture and into a volume adjacent the circuit board. A retainer is pivoted within the volume. The retainer is pivotally mounted to the plunger at the distal end of the plunger. The plunger is moved in a second direction to clamp the circuit board between the retainer and the circuit element.

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 common gate input circuit for III/V D-mode Buffered FET Logic (BFL) maximizes the dynamic range to drive a level shift section to set the proper voltage levels to switch the BFL and allows for decoupling of the switch point from the dynamic range. A common gate switching section includes a D-mode FET (FET1) configured as a load and a D-mode FET (FET2) configured as a common gate connected in series between high and low supplies Vdd and Vee1 (typically ground potential). The gate electrode of FET2 is coupled to Vee1 and the source electrode of FET2 is driven by the external digital signals. This eliminates the additional supply Vss, thus maximizing the dynamic range of the section to switch between Vdd and Vee1 and decouples the dynamic range from the switch point. An input level shift section may shift the Data In to the source electrode of FET2 to shift the switch point and to present a high input impedance.

Abstract: A method includes repeatedly determining a distance of an aircraft from a landing location. The method also includes, during a first stage in which the aircraft is at least a threshold distance from the landing location, performing iono-free processing during navigation of the aircraft. The method further includes, during a second stage in which the aircraft is less than the threshold distance from the landing location and a velocity of the aircraft is greater than a velocity threshold, performing divergence-free processing during navigation of the aircraft to address possible ionospheric threats. In addition, the method includes, during a third stage in which the aircraft is less than the threshold distance from the landing location and the velocity of the aircraft is less than the velocity threshold, calculating one or more floor values for a Differential Ionospheric Correction (DIC) sigma, and determining a navigation solution to protect against nominal ionospheric conditions.
