  • Patent number: 10860294
    Abstract: A requirements tracing validation tool analyzes an input corresponding to a requirements tracing set to identify high-level requirements and artifacts, subsystem-level requirements and artifacts, current links tracing between the requirements and the artifacts, and linguistic and logical elements of each identified artifact or link. The tool evaluates each link and provides a confidence level as to the correctness of the link. The tool may recommend additional links not already within the set and evaluate the recommended links for correctness. Further, the tool may evaluate the correctness of a given requirement over time as the requirements tracing set and its environment develops, and offer suggestions for amending the wording of artifacts and links to enhance uniformity and clarity throughout the requirements tracing set and increase the likely correctness of all traces and links within the environment.

  • Patent number: 10850868
    Abstract: A voter configured for in-flight tuning based on flight phase and operational scenario receives sensor signals and applies adaptive tolerances. The voter allows integration of high-integrity sensors with less accurate, low-integrity sensors, or even sensors that are susceptible to noise, dropouts, interference or sabotage without compromising the voted signal integrity or availability. The voter composites low-integrity sensor signals to produce a quasi-high-integrity sensor signal suitable for inclusion in a golden signal and provides sensor fusion.

  • Patent number: 10833772
    Abstract: A system for Nyquist zone disambiguation of a received broadband RF signal is disclosed. The system includes continuous-wave (CW) and pulsed photonic sources whose outputs may be combined into a single input. Both CW and pulsed components of the combined photonic input are modulated by sampling the received RF input signal. The system includes hybrid couplers for IQ demodulation of the modulated combined photonic signal. The system demultiplexes the demodulated inphase and quadrature differential photonic signals into their CW and pulsed component signals. The pulsed component signals may be digitized by narrowband multibit analog-digital converters (ADC) while the CW component signals are digitized by high speed low latency mono-bit ADCs to determine frequency components (e.g., bandwidth information) and other spectrum information of the RF input signal.

  • Patent number: 10831947
    Abstract: A method for optimizing the design of backplane and field bus routing for avionics network architectures determines a solution space of valid configurations defined by the intersection of universes corresponding to potential aircraft sensor locations, the data content relationships for each hosted application executing on the aircraft computing center, potential remote data concentrator (RDC) configurations, and potential backplane/field bus configurations for the avionics network architecture. The method includes identifying within the solution space, via an optimization engine, optimal configuration solutions of a desired optimality level based on connectivity constraints, system survivability constraints providing spatial separation of primary and redundant sensor and data collection systems, system robustness constraints associated with minimum functional capabilities for continued safe flight and landing capability, and an objective function characterizing overall desirability.

  • Patent number: 10820160
    Abstract: A system and method for HF positioning characterizes the undulations of the ionosphere in real-time to determine the refraction altitude of a specific HF frequency at a specific time of day at a specific position. The system accounts for the seasonal (summer, winter) and daily (daylight, night, grey-line transition) variations of the ionosphere determining a highly accurate timing error relative to a timing reference. The system employs a novel approach that is capable of passively and accurately determining a position anywhere in the world without use of a GNSS signal receiving known-time transmissions of narrow band HF timing signals refracted via ionospheric skywave.

  • Patent number: 10797920
    Abstract: System for generating a constant envelope and suppressed cyclic feature signal may include a transmission security (TRANSEC) function, a spread spectrum chip, an M-ary continuous phase modulator, and a pulse-shaped filter. The TRANSEC may generate a pseudorandom symbol by M-ary symbol generation selects a symbol with a signal phase, and the spread spectrum chip corresponding to the generated pseudorandom symbol or a phase rotation of the pseudorandom symbol. The M-ary continuous phase modulator with a delta-phase mapper maps the signal phase based at least in part on the selected symbol. The pulse-shaped filter of the M-ary modulator introduces inter-symbol interference from a previous and a subsequent symbol into a current symbol; the inter-symbol interference may be introduced by the main lobe of the signal phase being contained within a bandwidth of a chip rate of the spread spectrum chip for frequency modulation signal transmission of information by the generated signal.
