Abstract: Disclosed herein is a system that comprises one or more imaging sensors coupled to an aircraft and one or more navigation sensors coupled to the aircraft proximate to the one or more imaging sensors. The system further comprises an imaging module configured to capture images of a landing zone for the aircraft while the aircraft is in flight. The system additionally comprises a location determining module configured to associate a corresponding one of a plurality of location data with each one of the captured images. The plurality of location data is determined using one or more navigation sensors coupled to the aircraft. The system also comprises an object-identifying module configured to identify and locate one or more objects within the landing zone, relative to the aircraft, using the captured images and the location data associated with the captured images.

Abstract: In an example, a method for controlling a vehicle in a degraded visual environment is provided. The method includes identifying a degraded visual environment corresponding to a phase of a route followed by the vehicle. The method includes determining, based on the phase of the route, a first segment of a trajectory of the vehicle along which to search for a location with an improved navigation environment. The method includes causing the vehicle to follow the first segment until: (i) identifying the improved navigation environment, or (ii) reaching an end of the first segment without identifying the improved navigation environment. The method includes determining a second segment of the trajectory based on whether the improved navigation environment has been identified. The method includes causing the vehicle to follow the second segment.

Abstract: Rotor assemblies for aircraft are described that include a plurality of blades that are disposed vertically on a common axis along different horizontal planes. When the rotor assemblies are free-wheeling, the blades form a vertically stacked configuration, and when the rotor assembly is driven in rotation to generate lift, the blades bloom out from the vertically stacked configuration. At least one of the blades in the rotor assembly has a blade geometry that is different with respect to other blades such that when the blades are vertically stacked and free-wheeling, the collective shape of the blades is aerodynamic in shape, based on the different blade geometry, that reduces aerodynamic drag on the rotor assembly.

Abstract: A method of supporting robot(s) landing within a ground region is provided. The method includes accessing a map in which the ground region is tessellated into cells covering respective areas of the ground region. Each cell is classified as feasible to indicate a respective area is feasible for landing, or infeasible to indicate the respective area is infeasible for landing. The map is searched for clusters of adjoining cells that are classified as feasible, covering clusters of adjoining areas that define sub-regions within the ground region that are feasible for landing. The sub-regions are ranked according to a cost metric, and one of the sub-regions is selected according to the ranking. A geographic position of the selected sub-region is then output for use in at least one of guidance, navigation or control of the robot(s) to land at the selected sub-region within the ground region.

Abstract: The present disclosure relates to battery system having a plurality of battery modules and a battery management system. The plurality of battery modules are arranged in series to define a battery string. Each of the plurality of battery modules comprises a supervisory circuit, one or more cell packs, and one or more switches to electrically connect the one or more cell packs to the battery string. The battery management system to selectively switch, for each of the plurality of battery modules, the one or more switches between a first position that electrically places the one or more cell packs in series with the battery string and a second position that electrically bypasses the one or more cell packs from the battery string. The battery management system is configured to electrically couple the battery string with a battery bus via a string switch.

Abstract: An aircraft design optimization system and associated aircraft design optimization architecture. The aircraft design optimization system may comprise an input circuit to provide input data and an optimizer circuit to receive the input data and to communicate with a plurality of modules to create output data. At least one abstraction layer can be provided between the optimizer circuit and each of the plurality of modules. The optimizer circuit is configured to output the output data to a post-processing circuit. Each of the plurality of modules implements a different function.

Abstract: A method, apparatus, system for tracking an object, the method. A region of interest in an image pair is determined based on a bounding box determined for the object in the image pair. A mask based on the region of interest is applied to the image pair. The mask masks out portions of the image pair outside of the region of interest to form masked images. Intensity averaging is performed on the masked images to detect a set of pixels having a greatest intensity in the masked images. The set of pixels in the masked images is a set of common pixels in the masked images in which the set of common pixels is assumed to have a same location in both of the masked images. A three-dimensional position of the object is determined using the set of common pixels.
