    Abstract: Disclosed are systems and methods for reducing the amount of messaging between aerial vehicles and between controllers of aerial vehicles and simplifying aerial vehicle traffic management. In one implementation, a large service area, such as the United States, may be separated into a series of hierarchal regions. Rather than sending notifications to all agents (e.g., aerial vehicles, controllers) in the service area, each agent may subscribe to one or more regions of the hierarchal regions and only receive messages intended for the subscribed regions. In one example, as discussed below, messages for a particular region are only sent to agents subscribed to that region. Other agents within the larger service area do not receive the messages as they may not be relevant to those agents.

    Abstract: Systems and methods to improve stability and control of an aerial vehicle are described. For an aerial vehicle having a ring wing around a fuselage and a plurality of propulsion mechanisms, one or more sections of the ring wing may be pivotable to reduce vibrations and forces transferred to the aerial vehicle, and to prevent stall and minimize turbulence experienced by the aerial vehicle. The pivotable sections of the ring wing may be freely pivotable, may include locking elements to prevent or allow pivoting, may include bias elements or dampening elements to partially control the free pivoting, or may include actuators to effect desired pivoting.

    Abstract: The present disclosure is directed to controlling, reducing, and/or altering sound generated by an aerial vehicle, such as an unmanned aerial vehicle (“UAV”), while the aerial vehicle is airborne. For example, one or more transducers, such as piezoelectric thin-film transducers, or carbon nanotube transducers may be applied or incorporated into or on the surface of propeller blades that are used to aerially navigate the aerial vehicle. As the propeller blade rotates and generates sound, the transducers may be activated to generate one or more anti-sounds that cancel, reduce, or otherwise modify the sound generated by the rotation of the propeller blade. The anti-sound combines with the sound and causes interference such that the combined, or net-effect, is an overall cancellation, reduction, or other modification of the sound.

    Abstract: A multi-chamber device is described. The device can include a first chamber and a second chamber disposed within the first chamber. Each chamber may be formed from a flexible material. A first tube may extend between the first chamber and outside the first chamber to enable addition of gas to the first chamber. A second tube may extend between the second chamber and outside the first chamber to enable removal of gas from the second chamber.

    Abstract: Sounds are generated by an aerial vehicle during operation. For example, the motors and propellers of an aerial vehicle generate sounds during operation. Disclosed are systems, methods, and apparatus for actively adjusting the position of one or more propeller blade treatments of a propeller blade of an aerial vehicle during operation of the aerial vehicle. For example, the propeller blade may have one or more propeller blade treatments that may be adjusted between two or more positions. Based on the position of the propeller blade treatments, the airflow over the propeller is altered, thereby altering the sound generated by the propeller when rotating. By altering the propeller blade treatments on multiple propeller blades of the aerial vehicle, the different sounds generated by the different propeller blades may effectively cancel, reduce, and/or otherwise alter the total sound generated by the aerial vehicle.
