Abstract

A method is provided for supporting one or more ground vehicles on a mission that includes traversal of a ground region. The method includes accessing geospatial data produced from an aerial survey of the ground region, and performing an analysis of the geospatial data to produce terrain data that describes the ground region. The terrain data is weighted based on constraints of the one or more ground vehicles, and an order of priority of criteria of the mission. A map is constructed in which the ground region is expressed as a geospatially-mapped array of the weighted terrain data, and the map is searched for a path that meets the criteria of the mission. The path is described by a series of waypoints that define a route across the ground region, and an indication of the route is output for the one or more ground vehicles to traverse during the mission.

Abstract

Delivery systems for aerial vehicles may provide a passive automatic delivery system that is automatically triggered during landing of the aerial vehicle. One or more arm assemblies of the delivery system may include a respective landing arm, resilient member, and package guide. The landing arm is configured to rotate in response to an applied external force, with the resilient member being operatively coupled to the landing arm and configured to bias the landing arm towards a resting position. The package delivery system automatically releases the package when a delivery condition is met, such as the landing arms of the delivery system being rotated past a threshold position. Delivery systems can thus passively and automatically ensure that all landing arms are on a landing surface before the package is released. Related methods include approaching and contacting a landing surface, and releasing the package at the landing surface of the delivery location.

A jet valve includes a valve body, a juncture operatively coupled to the valve body. The juncture having a first fluid connection fluidly coupled to a header tank and a second connection fluidly coupled to a storage tank. A spool is movably disposed within the valve body. A jet pump is fluidly coupled to a fuel pump of the header tank via a bleed line. Operation of the fuel pump pressurizes the bleed line and moves the spool to a first position to (i) close a first fluid path between the header tank and the storage tank and (ii) provide a second fluid path between the header tank and the storage tank, the second fluid path through the aperture. Depressurization of the bleed line enables the spring to move the spool to a second position to close the second fluid path and open the first fluid path.

Abstract

A method for detecting change in a pair of sequential images. The method includes training a feature descriptor based on a generated training set of matching and non-matching image pairs. An imaging subsystem captures a pair of substantially sequential images of a field of view. The pair of captured images is aligned and then transformed into corresponding arrays of patches. A matching and non-matching probability is determined for each pair of adjacent patches based on the feature descriptor. Each pair of patches is classified as matching or non-matching based on a comparison of the matching and non-matching probability. A mask is generated identifying the pairs of patches that indicate change and then displayed overlaid on at least one of the sequential images to indicate change on a user interface.

Abstract

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.
