摘要： Apparatus and methods for controlling unmanned systems (UMSs), such as unmanned aircraft, are provided. A UMS can be provided that includes a physical computer, one or more auxiliary systems for the UMS, and a payload. The physical computer can execute software to cause the physical computer at least to instantiate a plurality of virtual computers that include a mission virtual computer and a payload virtual computer for: controlling the one or more auxiliary systems for the UMS using the mission virtual computer, communicating with the payload using the payload virtual computer, determining whether a software fault has occurred on one virtual computer of the plurality of virtual computers, and after determining that a software fault has occurred on one virtual computer of the plurality of virtual computers, preventing the software fault from causing a fault on a different virtual computer of the plurality of virtual computers.

摘要： Retention washers include a washer body having a first side and a second side opposite the first side. The washer body has a perimeter having one or more lobes, and the retention washer further includes a multi-point star-shaped hole extending through the washer body from the first side to the second side. The retention washer is configured to maintain an installation torque of an installed nut when the retention washer is positioned such that the hole circumscribes the nut. Systems for retaining a propeller assembly on a shaft may include a nut installed on a bolt, and a retention washer positioned such that the hole of the retention washer circumscribes the nut, thereby limiting rotation of the nut with respect to the bolt and retaining the nut on the bolt. The system may include a circular array of nuts and bolts, each nut having a respective retention washer positioned thereon.

摘要： Unmanned aerial vehicle (UAV) recovery is disclosed. An example apparatus to recover an unmanned aerial vehicle (UAV) includes a support rail to support a cable. The apparatus also includes a pivot arm to rotate about a pivot, where the cable is suspended between the support rail and the pivot arm, and where the pivot arm is rotated to a first orientation when the UAV contacts the cable and rotated to a second orientation when the UAV is brought to a stop. The apparatus also includes at least one of a friction device or a damper operatively coupled to the cable to resist motion of the cable during rotation of the pivot arm from the first orientation to the second orientation.

摘要： Apparatus and methods for controlling an aircraft and/or a vehicle are described. A vehicle speed and direction are received. A wind-over-vehicle speed and direction of wind at the vehicle are measured. An aircraft ground speed and direction are received. An aircraft-relative-to-vehicle speed and an aircraft-relative-to-vehicle direction are calculated based on the aircraft ground speed and direction and the wind-over-vehicle speed and direction. A wind-over-vehicle envelope is calculated based on system design limits for retrieving the aircraft at the vehicle. The wind-over-vehicle envelope maps limits of wind-over-vehicle speeds over a range of directions that enable retrieval of the aircraft at the vehicle. The aircraft and/or the vehicle are controlled using the wind-over-vehicle envelope, the aircraft-relative-to-vehicle speed, and/or the aircraft-relative-to-vehicle direction.

摘要： Example camera apparatus for generating machine vision data and related methods are disclosed herein. An example apparatus disclosed herein includes a first camera coupled to a movable turret and a second camera coupled to the movable turret. The first camera and the second camera are co-bore sighted. The first camera and the second camera are to generate image data of an environment. The example apparatus includes a processor in communication with at least one of the first camera or the second camera. The processor is to generate a first image data feed and a second image data feed based on the image data. The first image data feed includes a first image data feature and the second image data feed includes a second image data feature different than the first image data feature. The processor is to transmit the second image data feed for analysis by a machine vision analyzer.
