Abstract: An electrically-powered stores rack ejector for aircraft may be configured to carry and release stores (e.g., various munitions, such as missiles and/or bombs, and/or auxiliary fuel tanks). The stores rack ejector may include a housing and an ejector foot movably coupled to the housing, and the ejector foot may be configured to extend from the housing. The housing of the stores rack ejector may also include one or more suspension hooks movably coupled to the housing and the suspension hooks may be configured to release in conjunction with an extension of the ejector foot. One or more solenoids may be coupled to the ejector foot and may be energizable to cause the extension of the ejector foot. The stores rack ejector may also include a controller that may be configured to cause, based upon receiving a command associated with stores release, an energizing of the one or more solenoids.

Abstract: A unidirectional transfer protocol allows data to be transmitted from a non-secure network into a secure network. A non-secure gateway may receive data and/or information, intended for the secure network, from one or more devices. The gateway may fragment the data and/or information into smaller chunks and transmit the chunks to a secure gateway via a unidirectional communication channel. The secure gateway may verify the chunks using one or more rules and reassemble the chunks when the data is validated. The reassembled data may be sent across a secure network enclave. The unidirectional transfer protocol may provide a hardware-agnostic solution for transmitting data over a unidirectional communication channel.

Abstract: Search points in a search space may be projected onto images from cameras imaging different parts of the search space. Subimages, corresponding to the projected search points, may be selected and processed to determine if a target object has been detected. Based on subimages in which target objects are detected, as well as orientation data from cameras capturing images from which the subimages were selected, positions of the target objects in the search space may be determined.

Abstract: A process described herein may be used to determine a first asset's position in a GNSS-limited environment. The process includes transmitting a current position for each of at least three additional assets in wireless messages by wireless transmitters. The current position for each of the at least three additional assets is determined using previously received position data and one more additional measurement generated by instruments on board the additional assets. The transmitted messages are received at a device of the first asset and a processor on the device implements pre-programmed instructions to access the current position for each of the three additional assets and determine the first asset's position using the current position for each of the three additional assets.

Abstract: An aircraft diesel engine may be operated at a minimal fuel rate. Shaft output power of the engine may be reduced by initiating combustion during the compression stroke. Combustion may be initiated during the compression stroke by advancing fuel injection, splitting fuel injection, and/or manipulating individual injection quantities. Initiating combustion during the compression stroke may slew torque generation to the compression stroke.

Abstract: A substrate assembly includes at least one printed circuit (PC) substrate. Each PC substrate includes a PC top surface and a PC bottom surface spaced from each other and an edge that runs at least partially about a periphery of the PC substrate between the PC top surface and the PC bottom surface. The edge includes or defines on a facet or edge surface of the edge at least one projection that extends transverse or normal to the facet or edge surface. The projection includes a projection top surface and a projection bottom surface spaced from each other and the projection can include or be made of conductive material.

Abstract: Systems, methods and apparatus are described for a HERF weapon that may emit high-energy radio waves at a target based on locational information and a frequency associated with the target. The HERF weapon may receive the frequency and locational information from a sensing system. The HERF weapon may emit a high energy pulse toward the target and on the frequency associated with the target to disable or destroy the target without affecting nearby devices. The HERF weapon may allow the user to avoid detection by using a frequency that corresponds to the target's operating frequency.

Abstract: Systems, methods, and apparatuses are described for accelerating projectiles at high velocity. A barrel may include one or more heaters configured to heat a bore of the barrel prior to launch of a projectile. The barrel bore may be formed in a tungsten sleeve and may be heated to high temperatures. Heat from the barrel bore may be transferred to expanding propellant behind a projectile as it travels through the barrel bore.

Abstract: Systems, apparatuses, and methods are described for determining, based on blockchain, integrity of software and/or data stored on a vehicle. A computing device associated with a vehicle may determine one or more hash values for software and/or data stored on the vehicle. The computing device may receive values from read-only memory associated with the computing device and/or values from a blockchain of a distributed ledger system. The computing device may determine the integrity of the software and/or data based on the one or more hash values, the values from the read-only memory, and/or the values from the blockchain.

Abstract: Systems, methods, and apparatuses are described for verifying the authenticity of an integrated circuit device. An integrated test apparatus may use quiescent current and/or conducted electromagnetic interference readings to determine if a device under test matches the characteristics of an authenticated device. Deviations from the characteristics of the authenticated device may be indicative of a counterfeit device.

Abstract: A computer system receives a query and converts the query into one or more input data types each associated with a respective piece of input constraint data, and one or more output datatypes corresponding to desired data. A data path workflow scheme is created from the datatypes and a catalog of data path modules each of which has defined datatype of its input(s) and output(s) by building candidate data paths forward from the input and rearward from the output of the data path until data paths from all of the outputs connect with at least one of the data path inputs. The data path is then optimized and converted to an executable code data procedure and then run with the constraint data as the input to the procedure. The results can be displayed to a user display device by presentation modules based on the datatype of the output.

Abstract: A multi-mission munition adapter for an aircraft may be configured to attach to a hardpoint and hold a plurality of munitions, such as missiles and bombs. A top of the multi-mission munition adapter may have suspension lugs configured to attach to a hardpoint on an aircraft. Sides of the multi-mission munition adapter may have one or more launcher attachment fittings configured to attach missile launchers. A bottom of the multi-mission munition adapter may have one or more munitions ejector hangers configured to attach air-to-ground munitions ejectors. The adapter may comprise an electrical system that permits an aircraft to communicate with and/or power all functions of the bomb rack, missile launchers, and the weapons employed.

Abstract: A method of constructing conductive material in arbitrary three-dimensional (3D) geometries, such as 3D printing. The method may include selective application of an aerosol-based colloidal solution containing a catalytic palladium nanoparticle material onto a substrate and then immersion of the coated substrate into an electro-less plating bath for deposition of conductive copper material. The above steps may be repeated to create arbitrary 3D geometric constructs containing conductive metallic patterns.
