  • Patent number: 10124907
    Abstract: An avionics computing device of an aircraft including a rotor may include a non-transitory computer-readable medium and a processor communicatively coupled to the non-transitory computer-readable medium. Upon an occurrence of a condition indicative of a requirement to perform an autorotation maneuver, the processor may be configured to generate autorotation guidance commands based on a generated feasible three-dimensional autorotation trajectory. The generated feasible three-dimensional autorotation trajectory may be for the autorotation maneuver of an aircraft including a rotor. The generated autorotation guidance commands may be configured to guide a pilot of the aircraft to perform the autorotation maneuver of the aircraft along the generated feasible three-dimensional autorotation trajectory. The processor may further be configured to output data associated with the generated autorotation guidance commands to an input/output device for presentation to the pilot.

  • Patent number: 10114777
    Abstract: A system and related method for I/O synchronization in a high integrity multi-core processing environment (MCPE) incorporates logical computing units (LCU) of two or more homogeneous processing cores, each core running a guest operating system (GOS) and user applications such that the homogeneous cores concurrently generate the same output data (which the GOS loads to an I/O synchronization engine (IOSE)) or receive the same output data from the IOSE. The IOSE verifies data integrity by comparing the concurrently received datasets and selects a verified dataset for routing to other cores or externally to the MCPE. The IOSE receives and atomically replicates input data for synchronous transfer to, and consumption by, the user applications running on the cores of the LCU.

  • Publication number: 20180308401
    Abstract: A projector includes a first light modulator having first pixels, a second light modulator having second pixels, and a processing circuit. The processing circuit is configured to determine whether to control the spatial light modulators in a high-end mode or a low-end mode based on a video demand indicating greyscale levels. In high-end mode, at least one first pixel is driven in an ON state for at least a fraction of a frame time that a corresponding second pixel is in the ON state, the fraction determined based on the greyscale level. In the low-end mode, the at least one first pixel is driven in an OFF state while the corresponding second pixel is driven between ON and OFF states. The fraction that the second pixel is in the ON state is increased to compensate for driving the at least one first pixel in the OFF state.

  • Patent number: 10109054
    Abstract: Systems and a related method for monitoring commercial off the shelf (COTS) display devices in an avionics display system ensure that the COTS display devices are compliant with hazard classifications by positioning transparent photodetectors in the optical path to monitor the images and components generated and projected by the COTS display devices. Transparent photodetectors are positioned downstream in the optical path to monitor image orientation, refresh rate, or brightness of displayed images and image elements. The system may include transparent image sensors for capturing scene content and monitoring image integrity by comparing the captured scene content to the displayed images. Transparent image sensors positioned proximate to camera cores of an enhanced vision system (EVS) may verify the alignment of individual component image streams combined into an image stream displayed via HDD, HUD, HWD, or a like display element.

  • Patent number: 10095230
    Abstract: An autonomous vehicle system includes one or more output devices, one or more input sources, and a controller. In some embodiments, a verified inference engine is used by the controller to generate outputs for the output devices from inputs received from the input sources. The inference engine may be verified to be mathematically correct with an automated theorem proving tool. The automated theorem proving tool may verify that the inference engine meets the design requirements of standards such as DO-178C Level A and/or EAL-7. The controller is configured to validate the inputs received from the input sources, store the validated inputs in a fact base, generate outputs from the validated inputs, validate the one or more outputs, and provide the one or more validated outputs to the output devices.

  • Patent number: 10084529
    Abstract: A system and related method for minimizing co-channel interference in air-to-ground single-frequency networking includes aircraft-based directional and omnidirectional antenna arrays for transmitting to single frequency networks (SFN) (e.g., LTE, HSPA) and their cell sites. The directional array may encompass several cell sites to take advantage of C-RAN architectures. The system may default to the directional array to establish or re-establish network access, identifying accessible networks and sites and monitoring corresponding synchronization cell counts. The system may minimize co-channel interference with terrestrial network users by switching to the directional array if the count of accessible cell sites or networks becomes high enough, or due to additional factors (e.g., climbing above a threshold altitude). Similarly, the system may switch to the omnidirectional array if the cell count drops below a threshold level.
