  • Publication number: 20220150397
    Abstract: A method for identifying and correcting fixed pattern noise includes capturing a focused image and an unfocused image via a variable focus lens. Fixed pattern noise represented in the unfocused image is filtered from the focused image. The unfocused image represents a low-pass filtered component of the focused image; subtracting the unfocused image from the focused image results in a high-pass and fixed pattern noise filtered focused image. Image capture and focus of the variable focus lens are synchronized to remove transitional frames from the image stream.

  • Publication number: 20220148433
    Abstract: A system and method for identifying a safe path in a partially unknown environment in a time critical fashion includes identifying long range paths that avoid known obstacles. Short range paths within a receding horizon are identified corresponding to the long range paths, the short range paths avoiding known obstacles and unknown regions. Each short range path is broken into segments based on subsequent control operations or timing, and abort procedures are identified corresponding to each segment to enforce time critical availability of a safe action. Short range paths are excluded unless abort procedures can be identified for subsequent segments.

  • Patent number: 11329754
    Abstract: A system and method for including multiple data rate sub-blocks within a single data block includes dividing data blocks based on a priority or intended set of recipients. The sub-blocks are modulated at increasing data rates and the modulated sub-blocks are appended together and bounded by the known symbol blocks during transmission. The sub-blocks are organized in order of increasing data rate. During decoding, detected symbols of a first, low data rate sub-block are included in the detection process of higher data rate sub-blocks in place of additional symbols that would otherwise be needed for higher data rate transmissions. Alternatively, the sub-blocks may be organized with low data rate sub-block at the periphery and higher data rate sub-blocks in the interior such that the data block may be decoded from both ends.

  • Patent number: 11329375
    Abstract: A quadrature fed four-port radiating element is fed by an active quadrature combiner feed network. The active quadrature four-port combiner is ultra-wide band and includes RF signal amplification. The resulting feeder exhibits a size reduction over existing passive balanced/unbalanced technology on the order of five thousand to one. Such antennas may be incorporated into radio frequency integrated circuit transmit/receive modules. Such antennas may also be integrated with front end low noise amplifiers. Such feeder network enables practical implementation of two-port feeders compatible with AESA array lattice restrictions.

  • Publication number: 20220139235
    Abstract: A system and method for rendering near range weather information in a first aspect and mid-to-long range weather information in a second aspect includes transforming the mid-to-long range weather information to preserve certain relationships between the near range rendering and the mid-to-long range rendering while compressing distances to fit both renderings on a single display. Criticality metrics are maintained for the compressed mid-to-long range rendering by identifying the most critical weather indicator and applying it to the compressed weather cell rendering.

  • Publication number: 20220139241
    Abstract: A system and method for cooperative aerial vehicle collision avoidance provides an ESA-based sensor network capable of high-resolution threat proximity measurements and cooperative and non-cooperative collision avoidance in the full spherical volume surrounding an aerial vehicle. The system incorporates a plurality of ESA panels onto the airframe where the conical scan volumes overlap leaving no gaps in spherical proximity coverage. The resulting received data is stitched together between the neighboring ESA panels and used to determine a position and vector for each threat aerial vehicle within range. The data is transmitted through a cooperative collision avoidance network to nearby aerial vehicles, and presented to the autopilot and flight crew to increase situational awareness. The system determines a maneuver for the aerial vehicle and a maneuver for the threat aerial vehicle based on relative maneuvering capabilities to maintain desired separation.

  • Patent number: 11320980
    Abstract: A system for flight and task management timeline display is disclosed. In embodiments, the timeline display is positioned on an edge of a primary flight display (PFD) or other avionics display, divided lengthwise into time (e.g., absolute time) and space (e.g., relative time and distance) scales. The timeline display expands situational awareness into the temporal dimension by positioning waypoints in the flight path based on the relative time to passage or flyover. The time scale corresponds to an adjustable time range and automatically scrolls lengthwise according to the current time, but can be manually zoomed or scrolled in past and future directions as well. Based on updates from the flight management system (FMS), the space scale displays relative time-distanced events, notifications for reminders and tasks, and waypoints positioned according to the likely times they will be encountered (or, in the case of reminders and tasks, must be fulfilled).

  • Patent number: 11321463
    Abstract: A hardware malware profiling and detection system is disclosed. In embodiments, the system includes a primary (e.g., trusted) system including template processors and hardware sensors. The template processors submit input vectors to the primary system and characterize the system response via power trace data collected by the hardware sensors. Based on the input vectors and power trace data, the template processors generate system templates and derive system challenges therefrom. The template processors submit the system challenges to a remote system under test and characterize the remote system response in real time via identical remote hardware sensors. The template processors correlate the real-time remote system response data with the system templates corresponding to the issued challenges to detect system anomalies or malware within the remote system or its components.

  • Patent number: 11320650
    Abstract: A high-assurance headtracking system for a head worn display (HWD) incorporating ground-truth fiducials is disclosed. In embodiments, the headtracking system includes a camera fixed to a mobile platform (e.g., an aircraft cockpit) and oriented toward a pilot wearing the HWD. Images captured by the camera detect fiducial markers attached to the HWD (and fixed in a device reference frame) and static fiducial markers fixed to the mobile platform, each static fiducial marker including a constellation of individual markers having a known position and orientation in the platform reference frame. The headtracking system include control processors for analyzing the images and identifying therein the device-frame and static fiducial markers. The headtracking system determines a device pose of the HWD relative to the platform reference frame and monitors the device pose for drift or error based on the known positions of the identified static fiducial markers.
