Abstract: Embodiments are described for determining wind by an airborne aerial vehicle without reliance on direct measurements of airspeed by the vehicle. Instead, wind may be computationally estimated using disclosed techniques for utilizing measurements of only ground-speed and heading, or only measurements of forces experienced by the airborne aerial vehicle during flight. In one technique, samples of ground-speed measurements and corresponding heading measurements of an airborne vehicle are used in a mathematical optimization of a wind-driven hypothesis of deviations between the two types of measurement at each of multiple sampling times. In another technique, an aerodynamic model of an aerial vehicle can be used to adjust parameters of a wind hypothesis in order to achieve a best-fit between predicted and measured forces on the aerial vehicle during flight.

Abstract: An unmanned aerial vehicle (UAV) is disclosed that may allow for supervisory control interaction by a remote operator to assist with navigation to a target location. The UAV may navigate to a target area and capture and send an image of the target area to the remote operator. The remote operator can then provide a user input that indicates a target location within the target area. Upon receiving an indication of the target area, the UAV can then autonomously navigate to the target location. In some examples, after reaching the target location, the UAV may initiate delivery of a payload at the target location using a retractable delivery system while the UAV hovers above.

Abstract: In general, aspects of the present disclosure are directed to techniques for migrating social networking connections in a social network from one profile to another profile. A first incoming connection from a third profile in a social network to a first profile in the social network may be determined. A first outgoing connection to a fourth profile in the social network from the first profile in the social network may be determined. A second incoming connection from the third profile to a second profile may be created based at least in part on the first incoming connection. A second outgoing connection to the fourth profile from the second profile may be created based at least in part on the first outgoing connection.

Abstract: The present invention provides a system and method of providing encrypted data to a device. One or more public keys are received from the device and then validated. A request for the encrypted data is received from the device, and the encrypted data and a symmetric key used to encrypt the data is retrieved. The symmetric key is then encrypted using each of the one or more public keys, and the one or more encrypted symmetric keys and the encrypted data are sent to the device. This method can be implemented using a computer program with various code segments to implement the steps of the method. The system includes a processor, a data storage device communicably coupled to the processor and a communications interface communicably coupled to the processor. The processor executes the method as described above.
