    Abstract: Methods and systems for implementing trace deduplication are disclosed. One or more interactions between a plurality of components are determined. The interactions relate to a trace. A fingerprint for the trace is generated. The fingerprint is compared with a plurality of stored fingerprints representing a plurality of stored traces. The trace is stored if the fingerprint does not match any of the plurality of stored fingerprints. The trace is determined to be a duplicate if the fingerprint matches one of the plurality of stored fingerprints.

    Abstract: Uncrewed autonomous vehicles (“UAVs”) may navigate from one location to another location. Described herein are systems, devices, and methods providing countermeasures for threats that may compromise the UAVs. A plurality of UAVs may establish a mesh network to distribute information to one another. A first UAV may receive external data from a second UAV using the mesh network. The external data may be used to confirm or cross-check data such as location, heading, altitude, and so forth. Disagreement between data generated by the first UAV with external data from the second UAV may result in the determination that the first UAV is compromised. Remedial actions may be taken, such as the first UAV may be directed to a safe location to land or park, may receive commands from another UAV, and so forth.

    Abstract: This disclosure describes a configuration of an unmanned aerial vehicle (UAV) that will facilitate extended flight duration. The UAV may have any number of lifting motors. For example, the UAV may include four lifting motors (also known as a quad-copter), eight lifting motors (octo-copter), etc. Likewise, to improve the efficiency of horizontal flight, the UAV also includes a pushing motor and propeller assembly that is oriented at approximately ninety degrees to one or more of the lifting motors. When the UAV is moving horizontally, the pushing motor may be engaged and the pushing propeller will aid in the horizontal propulsion of the UAV.
