Abstract: A universal vehicle control router for fly-by-wire aircraft may include multiple vehicle control computers, such as flight control computers. Each flight control computer may be part of an independent channel that provides instructions to multiple actuators to control multiple vehicle components. Each channel is a distinct pathway capable of delivering a system function, such as moving an actuator. Each flight control computer may include a fully analyzable and testable voter (FAT voter). In the event of a failure to one of the flight control computers, the FAT voters may cause the failing flight control computer to be ignored or shut off power. Each flight control computer may comprise a backup battery. In the event of a power disruption from the primary power source, such as a generator and primary battery, the backup battery may power the flight control computer and all actuators.

Abstract: A mechanical controller provides four-axis control of a vehicle's position and movement. For example, the controller provides control of a vehicle's operations through a lateral axis, longitudinal axis, directional axis, and a grip axis (e.g., operating a thumbwheel of the mechanical controller that provides additional control inputs to the vehicle). The mechanical controller can provide independent force feel mechanisms in each of the lateral, longitudinal, and directional axes of movement. Additionally, the mechanical controller may provide a redundant force feel mechanism (e.g., for increased safety). For example, redundant springs and dampers may be incorporated in each axis's force feel mechanism. The mechanical controller may include a plunger and spring assembly to provide a force feel mechanism in the lateral and longitudinal axes. In addition to this spring force, surfaces of a contact region between the plunger and a plunger actuating plate may be shaped to produce force feel characteristics.

Abstract: Controlling aircraft traffic in an aerial network is described. A controller system identifies a departure site, an arrival site, a departure time interval, and an arrival time interval. Based on the on the departure site, the arrival site, and the departure time interval, the controller system generates a spatiotemporal region. A spatiotemporal region defines a three-dimensional perimeter that moves in time along a flightpath from the departure site to the arrival site. An aircraft is assigned to the spatiotemporal region and instructed to remain within perimeter of the spatiotemporal region as the aircraft travels from the departure site to the arrival site. The controller system monitors locations of the aircraft over time relative to the perimeter of the spatiotemporal region. If the aircraft deviates from the spatiotemporal region, the controller may transmit control instructions to the aircraft to return to the spatiotemporal region.

Abstract: Some embodiments relate to an electro-mechanical actuator that includes a screw, structurally segregated (split) housings, first and second nuts coupled to the screw, a sensor assembly, a plurality of motors, and a controller. The first nut is coupled to a first mounting point, and the second nut is coupled to a second mounting point. The sensor assembly may generate signals indicative of (e.g., relative) positions of left and right units of the actuator or positions of the first nut and the second nut on the screw. The controller controls the motors based on the signals generated by the sensor assembly. The motors may rotate each nut about a screw axis of the screw. This rotation results in one or both nuts moving along the screw. Movement between the first nut and the second nut along the screw adjusts a distance between the first mounting point and the second mounting point.

Abstract: A system and a method are disclosed for a vehicle control and interface system configured to facilitate control of different vehicles through universal mechanisms. The vehicle control and interface system can be integrated with different types of vehicles (e.g., rotorcraft, fixed-wing aircraft, motor vehicles, watercraft, etc.) in order to facilitate operation of the different vehicles using universal vehicle control inputs. In particular, the vehicle control and interface system converts universal vehicle control inputs describing a requested trajectory of a vehicle received from one or more universal vehicle control interfaces into commands for specific actuators of the vehicle configured to adjust a current trajectory of the vehicle to the requested trajectory. In order to convert the universal vehicle control inputs to actuator commands the vehicle control and interface system processes the universal vehicle control inputs using a universal vehicle control router.
