Abstract: Systems and methods to calibrate an imaging sensor may include an enclosure with a controlled environment, a light source illuminating the environment, and a particle source emitting desired particles at desired concentrations into the environment. An imaging sensor, which may be associated with an aerial vehicle, may be placed within the enclosure, and the imaging sensor may capture imaging data within the controlled environment. In addition, the imaging data may be processed to determine current spectral characteristics of the imaging sensor. Based on the environment, light, and particle properties within the environment, the imaging sensor may be calibrated to exhibit nominal or desired spectral characteristics.

Abstract: Described are example systems and methods that utilize simulated and/or actual flight data to determine an aerial delivery time estimate between a source location and a delivery destination, based on current flight conditions. For example, multiple flight simulations along a flight path between a source location and a delivery destination may be performed based on various different flight conditions and the flight time determined from the simulations may be maintained in a data store, associated with the flight path and simulated flight conditions. When a request for item information is received, current flight conditions may be determined and used to determine an estimated flight time based on stored simulated flight data having similar flight conditions to the current flight conditions.

Abstract: Systems, methods, and apparatus are provided for enabling orientation of directional antennas even when one or more of the directional antennas are moving. Position information for each directional antenna is transmitted using an omnidirectional antenna transmitting at a low bandwidth and a low power. The position information of the directional antennas is used to orient the directional antennas so that a high bandwidth, low power wireless connection can be enabled and/or maintained between the directional antennas. The position information is periodically transmitted and the orientation of the directional antennas is updated as one or more of the directional antennas move so that the wireless connection between the directional antennas is maintained.

Abstract: An airbag container may be inflated and used to protect an item placed within the airbag container. The airbag container may include an inflatable portion that includes sidewalls that extend between a cover to a base. The airbag container may include an orifice to receive gas to inflate the sidewalls, the cover, and the base to an inflation pressure. The airbag container may include an inner cavity defined within the sidewalls, the cover, and the base. The inner cavity may be unpressurized when the inflatable body is at the inflation pressure. The cover may be at least partially separable from the sidewalls to enable insertion of an item in the inner cavity. The cover may then be securable to the sidewalls to securely contain the item in the inner cavity.

Abstract: Described is an apparatus and method of an aerial vehicle, such as an unmanned aerial vehicle (“UAV”) that can operate in either a vertical takeoff and landing (VTOL) orientation or a horizontal flight orientation. The aerial vehicle includes a plurality of propulsion mechanisms that enable the aerial vehicle to move in any of the six degrees of freedom (surge, sway, heave, pitch, yaw, and roll) when in the VTOL orientation. The aerial vehicle also includes a ring wing that surrounds the propulsion mechanisms and provides lift to the aerial vehicle when the aerial vehicle is operating in the horizontal flight orientation.

Abstract: A system and method for operating an automated aerial vehicle are provided wherein influences of ground effects (e.g., which may increase the effective thrusts of propellers by interfering with the respective airflows) are utilized for sensing the ground or other surfaces. In various implementations, operating parameters of the automated aerial vehicle are monitored to determine when ground effects are influencing the parameters associated with the propellers, which correspondingly indicate proximities to a surface (e.g., the ground). Such ground effect sensing techniques may be utilized as a backup to other sensors (e.g., which may be determined to not be functioning properly and/or may be otherwise inhibited due factors such as to rain, snow, fog, reflections, bright sunlight, etc.)

Abstract: Noises that are to be emitted by an aerial vehicle during operations may be predicted using one or more machine learning systems, algorithms or techniques. Anti-noises having equal or similar intensities and equal but out-of-phase frequencies may be identified and generated based on the predicted noises, thereby reducing or eliminating the net effect of the noises. The machine learning systems, algorithms or techniques used to predict such noises may be trained using emitted sound pressure levels observed during prior operations of aerial vehicles, as well as environmental conditions, operational characteristics of the aerial vehicles or locations of the aerial vehicles during such prior operations. Anti-noises may be identified and generated based on an overall sound profile of the aerial vehicle, or on individual sounds emitted by the aerial vehicle by discrete sources.

Abstract: Sounds are generated by an aerial vehicle during operation. For example, the motors and propellers of an aerial vehicle generate sounds during operation. Systems, methods, and apparatus may actively adjust the position and/or configuration of one or more propeller blades of a propulsion mechanism to generate different sounds and/or lifting forces from the propulsion mechanism.

Abstract: This disclosure describes an aerial vehicle, such as an unmanned aerial vehicle (“UAV”), which includes a plurality of maneuverability propulsion mechanisms that enable the aerial vehicle to move in any of the six degrees of freedom (surge, sway, heave, pitch, yaw, and roll). The aerial vehicle may also include a lifting propulsion mechanism that operates to generate a force sufficient to maintain the aerial vehicle at an altitude.

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 shape of a propeller blade of an aerial vehicle during operation of the aerial vehicle. For example, the propeller blade may have one or more joints that adjust to alter the shape of the propeller blade. The altered shape of the propeller blade causes the propeller to generate different frequencies of sound as it rotates. By altering multiple propeller blades of the aerial vehicle, the different sounds generated by the different propeller blades may effectively cancel or reduce the total sound generated by the aerial vehicle, and/or alter the total frequency generated.
