  • Publication number: 20230032215
    Abstract: Systems and methods are described for time synchronization and message scheduling among network elements involving wireless nodes, data controllers, and a network manager. The network manager provides configuration information for the data controllers and the wireless nodes. The wireless node includes a timing circuit with a duty cycle which is initially configured based on the configuration information. Subsequent to the initial configuration, the network manager schedules polling requests for the data controller to transmit to the wireless nodes based on a time at which sensor data is received from the wireless nodes, thereby correcting for timer drift.

  • Patent number: 11164467
    Abstract: A method for an automated aircraft landing analysis including: receiving one or more aircraft landing performance parameters for one or more landing phases; determining a landing performance deviation for each of the one or more landing phases in response to the one or more aircraft landing performance parameters; identifying at least one of a system fault, a failure, and a pilot error that could have led to the landing performance deviations for each of the one or more landing phases; developing a fault tree for the landing performance deviations for each of the one or more landing phases; identifying measurable parameters, calculable parameters, inferable parameters, or observable parameters within the fault tree; converting the fault tree into a high level reasoning model using a standard inference methodology; performing a root cause analysis; identifying a root cause of the landing performance deviation; and displaying the root cause of landing performance deviation.

  • Patent number: 11153922
    Abstract: Disclosed is a method that includes receiving absolute wireless access point coordinates from wireless access points that define respective wireless access point positions of the wireless access points. The method includes orienting the directional antenna to orientations based on the absolute wireless access point coordinates. The method includes transmitting test signals to the respective wireless access points while the directional antenna is positioned at the orientations to generate the database entries associated with the respective wireless access point positions. The method includes orienting the directional antenna according to a first one of the database entries having a greatest likelihood to establish a first communications path between a first one of the wireless access points and the wireless endpoint. The method includes transmitting a data signal to the first one of the wireless access points with a minimum transmission power based on the database entries.
