Abstract:
A system for positioning an unmanned aerial vehicle is provided including a position reference system including an electromagnetic radiation transmitter configured to modulate a transmission signal to encode location information associated with a coordinate system relative to the electromagnetic radiation transmitter. The system further includes an unmanned aerial vehicle including at least one control device configured to control a position of the unmanned aerial vehicle and an electromagnetic radiation receiver configured to receive the transmission signal. The unmanned aerial vehicle further includes a control system configured to control the at least one control device based at least in part on the location information received by the electromagnetic radiation receiver.
Abstract:
A method includes receiving, via at least one sensor of a robot, sensor data indicating one or more characteristics of an asset. The method includes detecting, based on the sensor data, an existing or imminent defect of the asset. The method includes fabricating a part suitable for use in correcting the defect. The structure of the part is derived using one or both of a digital representation of the asset generated using the sensor data or stored reference data related to the asset.

Abstract:
A system and method for guiding and coordinating vehicular traffic determine tasks to be completed by vehicles in a transportation network in order to complete an objective, allocate the tasks among the vehicles, and determine sets of allowable actions for the vehicles based on the allocation of the tasks. The sets of allowable actions dictate plural different allowable actions that the vehicles are allowed to perform in order to complete the tasks allocated to the vehicles. The allowable actions are determined such that the vehicles are scheduled to complete the tasks and complete the objective without the vehicles colliding or blocking movement of each other. The allowable actions are communicated to the vehicles such that the vehicles are permitted to select one or more of the allowable actions and prohibited from performing one or more other actions during performance of the tasks allocated to the vehicles.
Abstract:
A method for identifying variations in aircraft operational parameters includes processing a four-dimensional (4D) aircraft trajectory for a flight along a defined route. The method also includes determining an aircraft intent corresponding to the flight along the defined route based at least in part on an aircraft performance model from a trajectory predictor. The aircraft intent includes multiple segments and corresponding intent parameters. In addition, the method includes adjusting the intent parameters such that a computed 4D trajectory substantially corresponds to the 4D aircraft trajectory. The method further includes determining a computed operational parameter based at least in part on the computed 4D trajectory and the aircraft performance model from the trajectory predictor. In addition, the method includes identifying variations between the computed operational parameter and a corresponding measured operational parameter.
