Abstract:
Systems and methods are provided for converting taxiway voice commands into taxiway textual commands. In various embodiments, the systems can comprise a radio receiver that is configured to receive the taxiway voice commands from an air traffic control center, a voice recognition processor coupled to the radio receiver that is configured to receive and convert the taxiway voice commands into the taxiway textual commands, and/or a taxiway clearance display coupled to the voice recognition processor that is configured to receive and display the taxiway textual commands.
Abstract:
The radio system comprises a radio unit and an antenna unit coupled to the radio unit. The antenna unit is physically separate and located remote from the radio unit. The antenna unit further comprises a digital (pre-distortion engine configured to pre-distort a modulated digital data signal; a digital to analog converter configured to convert the pre distorted digital data signal to a pre-distorted analog data signal; and a power amplifier configured to amplify the pre-distorted analog data signal which distorts the pre-distorted analog data signal. The distortion introduced by the power amplifier is opposite to the pre-distortion introduced by the digital pre-distortion engine such that the pre-distortion introduced by the digital pre-distortion engine approximately cancels the distortion introduced by the power amplifier. The radio unit further comprises a coefficient computation engine configured to calculate coefficients used by the digital pre-distortion engine to pre-distort the modulated digital data signal.
Abstract:
A method for sending environmental data to a vehicle in transit is disclosed. The method is performed by a ground system. The method includes receiving new environmental data from a plurality of environmental data providers. The method also includes synthesizing an update template that identifies recommended portions of relevant data that are available to be uploaded for at least one of a plurality of environmental data services. The method also includes sending the update template to the vehicle using a low-bandwidth connection, wherein the update template is sent by the ground system without first receiving a request for the update template. The method also includes receiving, from the vehicle, a request for the recommended portions of relevant data. The method also includes sending the recommended portions of relevant data to the vehicle in an update package using a high-bandwidth connection.
Abstract:
A significant weather advisory system for an aircraft is disclosed. The system is configured to identify, from strategic weather data, current significant weather events from weather impacted areas projected to be intersected by a geographical corridor around a projected flight path and projected to occur during determined time intervals during which the airborne vehicle is expected to pass through the weather impacted areas; compare the current significant weather events to previously identified significant weather events and detect significant changes between the current significant weather events and the previously identified significant weather events; and generate a notification for display to the flight crew via an onboard notification system that identifies the detected significant change when a significant change is detected.
Abstract:
A method for providing environmental data to a vehicle such as an aircraft is provided. The method includes receiving a request from a vehicle to provide environmental data, and defining a route plan vicinity area as a part of a coverage polygon. The method further includes receiving alternate/back-up destinations selected from a list and defining and including in the coverage polygon one or more connection areas between the route plan vicinity area and the selected alternate/back-up destinations. The method smooths the coverage polygon and assembles environmental data for the smoothed coverage polygon. The assembled environmental data is sent to the vehicle.
Abstract:
A processor-implemented method for dynamic contrast equalization for a see-through display subject to varying light conditions is provided. The method comprises: generating an intensity map for the field of view of the see-through display using a selected image portion of the retrieved image that is coextensive with the field of view of the see-through display; determining, using the intensity map, one or more sectors of the see-through display, on which a set of pixels corresponding to symbology in an overlay is to be displayed, that are in a high light intensity area; applying a filter to the see-through display at the one or more sectors of the see-through display to block a portion of light emanating from an external environment in the field of view of the see-through display; and displaying the overlay on the see-through display wherein the symbology is displayed over the one or more sectors.
Abstract:
In some examples, a system is configured to determine a reliability index for weather information received by a weather system. The reliability index may indicate a degree of confidence of the accuracy of the weather information. For example, a system may determine a weather product for each of one or more voxels of a plurality of voxels in a three-dimensional or four-dimensional volumetric buffer, and based on a combination of the weather product and the weather information, determine a reliability index for the weather product. The system may display a first visual representation of the weather product and a second visual representation of the corresponding reliability index.
Abstract:
A method for managing a flight briefing data system is provided. The method establishes, by a central computer system, a first communication connection with an electronic device and a second communication connection with an aircraft onboard avionics unit; transmits, by the central computer system, flight briefing data via the first communication connection and the second communication connection, wherein the flight briefing data comprises at least a plurality of Notices to Airmen (NOTAMs) associated with a pending flight; receives, by the central computer system, altered flight briefing data; and synchronizes the central computer system, the electronic device, and the aircraft onboard avionics unit, by transmitting the altered flight briefing data via the first communication connection and the second communication connection.
Abstract:
A plurality of antenna elements may receive a plurality of signals. Each of the plurality of antenna elements may correspond to at least one of a plurality of sectors of a sectorized antenna. A receiver may process each of the plurality of signals in parallel, including decoding one or more messages from the plurality of signals. The receiver may output at least one of the one or more messages.
