  • Patent number: 12007774
    Abstract: A system and method for integrity monitoring generates primary control output via a primary module. The primary control output is configured to be used to control an autonomous vehicle (AV). The system and method receive situational data comprising AV data and environmental data. The system and method generate, using a monitor module configured to monitor the AV, a set of fallback actions based on at least the situational data. The system and method generate, using the monitor module, a fallback status based on at least the set of fallback actions, where the fallback status is configured to correspond to a determination of whether to override the primary control output.

  • Patent number: 12005163
    Abstract: A system and method for sterilizing recirculated airflow in closed environments, as well as certain types of material equipment includes electronically steered antenna (ESA) elements. The ESA elements operate in radio frequencies (RF). The ESA elements produce directed beams of microwave radiation to sterilize surfaces or volumes of air. The directivity gain associated with the beam forming increases RF energy density in the area where the beam is steered.

  • Patent number: 12003262
    Abstract: A system and method for selectable sampling of a received RF input spectrum copies the input signal into a set of equivalent input spectra, one for each of a set of parallel sampling paths. The sampled input spectra are converted to a common sampling rate (e.g., baseband I/Q stream) and demodulated into a digital signal for each current time window of a sequence of time windows based on the common rate and corresponding to the receiver output stream. For each current time window, evaluation blocks store the demodulated signals to memory and evaluate the signals for signal quality, distortion, and/or receiver sensitivity based on figures of merit (FOM) determined by the waveform. The highest quality demodulated signal is selected, retrieved from memory, and appended to the digital output stream, providing low distortion demodulated digital output based on the RF input signal in real time or near real time.

  • Patent number: 12002371
    Abstract: An onboard aircraft landing system includes one or more event-based cameras disposed at known locations to capture the runway and visible surrounding features such as lights and runway markings. The event-based cameras produce a continuous stream of event data that may be quickly processed to identify both light and dark features contemporaneously, and calculate an aircraft pose relative to the runway based on the identified features and the known locations of the event-based cameras. Composite features are identified via the relative location of individual features corresponding to pixel events.

  • Patent number: 12000946
    Abstract: A system and method established and maintains precision relative position, navigation, and timing (PNT) across a network of at least four mutually connected mobile platforms. In embodiments, a key (e.g., advantaged, absolute positioning capable) node of the network determines its pressure altitude and inertial state relative to its platform reference frame and receives inertial state and pressure altitude data from each neighboring node (in exchange for its own) to estimate the relative position and orientation of each neighbor node in its platform frame. The key node performs ranging to each neighboring node, and the neighboring nodes additionally range between each other and exchange ranging data with the key node. By correcting position and orientation estimates via ranging data, the key node determines and maintains extended relative PNT (e.g., in GPS-denied areas), which relative PNT solution is distributed across all network nodes.

  • Patent number: 12002369
    Abstract: An aircraft-based display system providing a graphical user interface (GUI) for display of terminal charts further displays an enroute selector for engagement to select and display enroute charts. Engagement with the enroute selector brings up an enroute menu for selecting for display enroute charts associated with the ownship position or previously selected enroute charts; selection of an enroute chart 1) makes the selected chart the new active enroute chart and 2) displays the enroute chart. Each chart in the enroute menu includes a play button; engagement with the play button brings up an enroute selector GUI allowing selection of an enroute region and chart type. The enroute selector GUI displays all available enroute charts for a selected region and chart type, allowing the selection and display of the desired enroute chart in graphical as well as textual format.

  • Patent number: 11995228
    Abstract: A system and method for head tracking for a head worn display (HWD) includes head-frame and platform-frame IMUs providing high-rate pose data of the wearer's head and a mobile platform. An optical tracker estimates an optical pose of a camera oriented at fiducials based on a comparison of 2D image data captured by the camera (and portraying the fiducials within the image) and the known location of each fiducial in a 3D marker frame. The pIMU also provides low-rate, high-integrity georeferenced pose data of the mobile platform (e.g., in an earth frame). The head tracker provides low-rate, high-integrity absolute head pose solutions (e.g., user head pose in the earth frame) based on the georeferenced pose data and current high-rate head/platform pose data, updating the absolute pose solutions with high-rate updates based on combined extended Kalman filter propagation of the high-rate head and platform pose data with refined optical pose data.

  • Patent number: 11982922
    Abstract: A system is described. The system includes HNLF for generating an optical frequency comb and a single mode fiber for reducing a pulse duration of comb. The system includes a FRM to reflect the light in back propagation through the HNLF and the single mode fiber. Perturbations in a state of polarization caused by the HNLF and the single mode fiber are cancelled between the forward propagation and the backward propagation.

  • Patent number: 11979203
    Abstract: A set of stators of a linear induction motor are mounted on a track. A three-phase current is provided to each of the stators, such that a traveling magnetic field (TMF) is created by the stators along the length of the track. The traveling magnetic field includes a magnetic flux corresponding to a stator excitation modulated with a message signal. A rotor includes a series of conductor plates. As the traveling magnetic field passes through the conductor plates, a current is induced in the plates by induction. Such current then generates an opposing magnetic field causing the plates and the vehicle to be propelled. Each phase may first be modulated with a message signal, before being provided to the stator. The current at the rotor is then demodulated to realize the message signal. A doppler shift due to the speed of the rotor relative to the stator is corrected.
