A system and method for detection of an aerial drone in an environment includes a baseline of geo-mapped sensor data in a temporal and location indexed database formed by (i) using at least one sensor to receive signals from the environment and converting into digital signals for further processing; (ii) deriving time delays, object signatures, Doppler shifts, reflectivity, and/or optical characteristics from the received signals; (iii) geo-mapping the environment using GNSS and the sensor data; and (iv) logging sensor data over a time interval, for example 24 hours to 7 days. Live sensor data can be then be monitored and signature data can be derived by computing at least one parameter such as direction and signal strength. The live data is continuously or periodically compared to the baseline data to identify a variance, if any, which may be indicative of a detection event.

An aircraft equipped with a multi-fan propulsion system for controlling flight orientation transitions is provided. In one example aspect, an aircraft includes a fuselage and a pair of wings. The aircraft includes a propulsion system having a first propulsor and a second propulsor each mounted to the fuselage. The first propulsor has a fan positioned primarily above and the second propulsor has a fan positioned primarily below the pair of wings. The aircraft also includes a computing system having one or more processors configured to cause, in response to a demand to change an orientation of the aircraft for a flight orientation transition, the fans of the first and second propulsors to produce different amounts of thrust with respect to one another so that the aircraft performs the flight orientation transition. The thrust differential causes the aircraft to transition between orientations.

Disclosed is an aircraft and a method of controlling an aircraft. The aircraft comprises a continuous wing assembly extending from port to starboard sides of the aircraft. The aircraft is controlled partially by flexing portions of the wing, and partially or totally by mechanical systems that alter the position of a fuselage with respect to the wing. The fuselage is attached to the wing by a wing/fuselage joint structure that permits at least two mutually orthogonal axes of rotation of the fuselage relative to the wing. The aircraft includes a sensors, a telemetry system linked to a remote server, and a control system for programming flight information and aircraft control instructions and a plurality of actuators responsive to the control system for rotating the fuselage relative to the wing and flexing the wing for controlling the flight of the aircraft in response to instructions from the control system.

A biological sample test system and method includes a remote sample delivery system, configured to secure a container for a biological sample, the container including a sample identifier. A sample receiving station is configured to receive the container from the remote sample delivery system based on the sample identifier. The remote sample delivery system is configured to automatically navigate to the sample receiving station upon the container being secured to the remote sample delivery system. A sample test track, comprising a plurality of test stations and a container conveyance system configured to sequentially deliver the container to individual ones of the plurality of test stations based, at least in part, on sample identifier.

Methods, systems, and devices for wireless communications are described. In a wireless communications system, a base station may transmit an indication of a pre-compensation timing value for transmission of a random access message by an aerial user equipment (UE), the random access message part of a random access procedure between the base station and the aerial UE when the aerial UE is in a connected state. The pre-compensation timing value may be based on a location of the aerial UE. In some examples, the base station may monitor a set of random access resources associated with the pre-compensation timing value and the aerial UE for the random access message, and the aerial UE may transmit the random access message using a first random access resource of a set of random access resources associated with the pre-compensation timing value and the aerial UE.
