Abstract: Systems and methods are provided for aerostat deployable from sonobuoy launch container. One embodiment is an apparatus that includes a capsule configured to launch from an aircraft and float in seawater with one or more sonobuoys. The capsule includes a receiver configured to receive sonobuoy data from the one or more sonobuoys, a transmitter configured to transmit the sonobuoy data to the aircraft, a cable configured to power the transmitter via a battery, and a reaction chamber including a reactant and configured to generate a gas from the seawater mixing with the reactant. The capsule also includes an aerostat tethered to the capsule via the cable and configured to inflate with the gas produced by the reaction chamber, and to ascend above the capsule with the transmitter to increase a distance for transmitting the sonobuoy data to the aircraft.

Abstract: A device is configured to estimate a gaze target of a user of an augmented reality headset based on vehicle sensor data and headset sensor data. The device is configured to generate visualization data based on the gaze target. Responsive to determining that the gaze target is inside a first vehicle, the visualization data includes a first visual depiction of a first point of interest that is outside the first vehicle. The first point of interest includes at least a portion of a particular route of a particular vehicle. The particular vehicle includes the first vehicle or a second vehicle. Responsive to determining that the gaze target is outside the first vehicle, the visualization data includes a second visual depiction of a second point of interest that is inside the first vehicle.

Abstract: A device is configured to determine a movement of a vehicle based on vehicle sensor data, and a movement of an augmented reality (AR) headset based on headset sensor data. The device is configured to estimate a user portion of the movement of the AR headset caused by a movement of a user and not caused by the movement of the vehicle. The device is configured to determine a gaze target of the user based on the user portion and to generate visualization data based on the gaze target. Responsive to determining that the gaze target is inside the vehicle, the visualization data includes a first visual depiction of a first point of interest that is outside the vehicle. Responsive to determining that the gaze target is outside the vehicle, the visualization data includes a second visual depiction of a second point of interest that is inside the vehicle.

The device is configured to estimate a user portion of the movement of the AR headset caused by a movement of a user and not caused by the movement of the vehicle. The device is configured to determine a gaze target of the user based on the user portion and to generate visualization data based on the gaze target. Responsive to determining that the gaze target is inside the vehicle, the visualization data includes a first visual depiction of a first point of interest that is outside the vehicle. Responsive to determining that the gaze target is outside the vehicle, the visualization data includes a second visual depiction of a second point of interest that is inside the vehicle.

Abstract: An unmanned aerial vehicle (UAV) launch system includes a launch container including a housing defining an internal chamber. A UAV includes a main body defining an inflatable envelope. The UAV is configured to be contained within the internal chamber. The main body is in a deflated state when the UAV is contained within the internal chamber. A reactant is configured to react with water to produce a lifting gas. The inflatable envelope is configured to be inflated by the lifting gas in response to the reactant reacting with the water to deploy the UAV from the launch container.

Abstract: Systems and methods using Information-invariant Data Transformation (IIDT) in the transfer of files from an un-trusted to a trusted computer system are disclosed. The IIDT alters the data representation of information, without altering the meaning of the information to a degree that is perceptible to a human consumer of that information. The data transformation operations eliminate embedded malware thereby providing secure transfer of files between the un-trusted and trusted computer systems.

Abstract: A computer network is disclosed that includes a first domain and a second domain. The second domain has a higher security classification than the first domain. The computer network also comprises a Temporal Separation Cross Domain Gateway (TSEP-CDG) having a temporal separation hardware interlock. The interlock is configured to physically prevent communication between the first and second domains. It connects with the first domain in a first state to allow the TSEP-CDG to receive data from the first domain. The TSEP-CDG executes an information-invariant data transformation (IIDT) on the received data before it is available to the second domain. The IIDT alters the representation of the data while conveying the same information, disrupting anti-malware present in the received data. The temporal separation hardware interlock is configured for connection with the second domain in a second state to allow the TSEP-CDG to transmit the transformed data to the second domain.
