  • Patent number: 10938734
    Abstract: A device for avionics full-duplex switched Ethernet (AFDX) communication can include a transmit port for transmitting AFDX data and a processor. The processor can be configured to obtain AFDX data frames for transmission over a plurality of sub-virtual links (subVLs) of a virtual link (VL), and maintain, for each of the plurality of subVLs, a corresponding data queue by storing AFDX data frames associated with that subVL in the corresponding data queue. The processor can transmit the AFDX data frames from the plurality of data queues on the plurality subVLs via the transmit port according to a scheduling policy that is based on subVL prioritization. The scheduling policy that is based on subVL prioritization can include static priority (SPn) scheduling, earliest deadline first (EDF) scheduling, or least laxity first (LLF) scheduling.

  • Patent number: 10939511
    Abstract: A solid-state radio frequency (RF) microwave oven for an aircraft galley is dimensioned to fit the galley and includes within the oven cavity an array of RF modules disposed on the upper interior surface of the cavity. Each RF module includes one or more RF emitters programmable to heat meals placed within the oven cavity by emitting tunable RF signals. The RF modules may monitor the internal temperature and doneness of the food by detecting returned unabsorbed energy. An oven control module (OCM) may communicate with the aircraft galley network, selectively manage the activation and deactivation of RF modules depending on the food being cooked and its changing internal temperature, and tune emitted RF signals to avoid interference with aircraft communication systems. Compact heat sinks may be located within the rear of the oven cavity for the removal of excess energy from the oven.

  • Patent number: 10909715
    Abstract: A head tracking system uses coded features, highly structured compared to the operating environment, to ensure a high-integrity correspondence map. Coded features can be used to provide a negligible probability of spurious features and probability of misidentification. Ensuring a reliable correspondence map prevents unmodeled errors that arise from an invalid correspondence map. In the case of multiple outliers, existing screening techniques, such as random sample consensus (RANSAC) or fault exclusion, may be used to eliminate excessive outliers. Mature GPS integrity techniques may then be extended to optical pose estimation to establish integrity bounds for single faults that may go undetected by fault detection.

  • Patent number: 10908277
    Abstract: Separation distances between a platform and an air or weather anomaly such as a wake vortex are obtained. Airspeeds of the air or weather anomalies are detected. Maximum airspeeds determined from different detection paths may result one or more airspeed differentials. The one or more airspeed differentials may be used to determine a calculated separation distance. A position of the platform may be maintained or maneuvered relative to the air or weather anomaly based on the calculated separation distance. Control commands may be output to a vehicle control system to perform, direct, or display a navigational solution including maneuvering relative to the air or weather anomaly, where the vehicle control system may include a graphics controller, a flight control system, a flight management system, or an autopilot.
