Abstract: Systems and methods for radar-based aircraft maneuver actions are provided. An example computer-implemented method includes transmitting, using one or more transmitters onboard an aircraft, one or more radio signals. Reflected radio data corresponding to one or more radio signals reflected from a plurality of radio detection and ranging (“radar”) reflectors placed at a plurality of locations associated with an aerial facility can be received using one or more radio receivers onboard the aircraft. A location for the aircraft can be computed based on the radio data and the plurality of locations associated with the aerial facility at which the radar reflectors are placed. A maneuver action for the aircraft can be initiated at a particular landing pad of the aerial facility based on the location.

Abstract: Systems and methods for controlling aerial vehicles are provided. An aerial vehicle includes a single circuit board with a number of processor devices and a memory including instructions to perform autonomy operations. The autonomy operations include obtaining GNSS data from GNSS assemblies electrically connected to the processor devices, APNT data from APNT assemblies electrically connected to the processor devices, and radar data from the radar assemblies electrically connected to the processor devices. Each of the assemblies are disposed on the same circuit board that includes the number of processor devices. The processor devices determine a vehicle location based on the GNSS data, the APNT data, and the radar data, identify airborne objects based on the radar data, generate a motion plan based on the vehicle location and the identified objects, and initiate a motion of the aerial vehicle based on the vehicle location.

Abstract: A method of thermomechanically forming, for example forging, rolling, extruding or drawing, an article from a precursor thereof, is described.

Abstract: A method and an antenna system are provided for a high-altitude platform (HAP) configured to move in a pattern in the stratosphere to provide coverage to a region of interest and compensate for HAP movement relative to the region of interest. HAP movement is monitored. When it is determined that the HAP has moved relative to the region of interest and, based on the relative movement, a first one of a plurality of antennas in the HAP is no longer able to cover a selected portion of the region of interest, an antenna array switching circuit in the HAP is used to adjust beams transmitted by the antennas by switching to a second one of the plurality of antennas to cover the selected portion of the region of interest, such that the communication services provided to the region of interest are not interrupted due to the movement of the HAP.

Abstract: Aspects of the disclosure provide for an antenna system. The antenna system includes a main reflector, a phased array feed, and a mechanical steering system. The phased array feed is configured to receive and/or transmit signals reflected off the main reflector and to electronically steer a transmitted signal on a first axis. The main reflector and the phased array feed are both attached to the mechanical steering system, and the mechanical steering system is configured to move the transmitted signal along a second axis.

Abstract: An apparatus and method for adapting web page content are described. The adaptation of web page content for display on smaller intended display devices often requires the splitting of the content over a number of smaller pages. The apparatus and method relate to a procedure which integrates the process of splitting the content with applying transformations (for example, reducing the font size, images, etc) so as to optimise this process. The procedure is carried out systematically over the entire web page content, recursively splitting the content into smaller and smaller portions whilst simultaneously alternating this with various transformations so as to minimise the amount of white space visible on the smaller pages. Additionally, the preferred embodiment also tracks the transformations which have been applied to the objects and ensures consistency by applying them later to any similar objects.
