Abstract:
A technique of controlling tonal noises produced by an unmanned aerial vehicle (UAV) includes generating thrust with a plurality of rotor units mounted to the UAV to propel the UAV into flight. Each of the rotor units includes a bladed rotor. A rotation rate or a phase delay of at least one of the rotor units is adjusted relative to another of the rotor units. The adjustment causes a spread in the tonal noises generated by the rotor units.
Abstract:
Example embodiments may relate to web interfaces for a balloon-network. For example, a computing device may display a graphical interface that provides information related to a balloon network configured to provide service in a geographic area, where the graphical interface includes a map. The computing device may receive real-time bandwidth data related to balloons in the balloon network, where the balloons are each configured to change position via altitudinal movement and via horizontal movement with respect to the ground. Based at least in part on the received real-time bandwidth data, the computing device may display, on the map, a visual representation of bandwidth information corresponding to one or more regions in the geographic area, where the visual representation of bandwidth information updates from time to time based at least in part on a change in position of one or more balloons in the balloon network.
Abstract:
The present disclosure relates to a deployment system for an unmanned aerial vehicle (UAV). In one aspect, an illustrative deployment system includes a communication system configured for receiving diagnostic data corresponding to an object included in a UAV, wherein the UAV has an expiration condition; and a logic module configured for (i) determining that the expiration condition has been satisfied based, at least in part, on the received diagnostic data, and (ii) responsive to determining that the expiration condition has been satisfied, initiating an action that includes sending to the UAV both (a) navigation data relating to a remedial facility, and (b) instructions to navigate to the remedial facility based, at least in part, on the navigation data.
Abstract:
The present disclosure provides methods operable in a balloon network. The method can include determining that a balloon is at a location associated with a legally-defined geographic area. An area profile of the legally-defined geographic area may identify geographically-restricted data that must not be removed from the legally-defined geographic area. The method can also include determining that the balloon contains at least some of the geographically-restricted data. The method can also include determining that the balloon is likely to move out of the legally-defined geographic area. The method can also include removing the geographically-restricted data from the memory of the balloon.
Abstract:
The optical tracking module includes an optical phased array (OPA), an analog drive, an integrated photodetector, and one or more processors. The OPA includes a plurality of array elements, and a plurality of phase shifters. The analog drive is configured to adjust the plurality of phase shifters. The integrated photodetector is configured to receive light from the OPA. The one or more processors is configured to extract signal information of an incoming beam via the OPA, and control an outgoing beam using the analog drive based on the signal information. The OPA, the analog drive, the integrated photodetector and the one or more processors are in an integrated circuit.
Abstract:
In one aspect, there is provided a marine sensor platform that includes: a line having a plurality of slots that are spaced apart on the line, a plurality of sensor nodes, each sensor node configured to couple to each of the slots on the line, and each sensor node including at least one sensor, a power source coupled to the plurality of sensor nodes and configured to supply power to the plurality of sensor nodes on the line, and a controller coupled to the power source and the plurality of sensor nodes on the line, wherein the controller is configured to identify a type of the at least one sensor included in each of the sensor nodes when each of the sensor nodes is coupled to the respective slot on the line.
Abstract:
Embodiments relate to a marketplace for inter-network links between a high-altitude network and a terrestrial data network. An example method may involve a computer-based purchasing agent: (i) determining a demand for inter-network bandwidth between a high-altitude network and a terrestrial data network, (ii) determining one or more offers to provide an inter-network link, wherein the inter-network link provides inter-network bandwidth between the high-altitude network and the terrestrial data network, and wherein each offer is associated with a corresponding client device, (iii) based at least in part on a comparison of: (a) the demand for inter-network bandwidth and (b) the one or more offers to provide an inter-network link, selecting one or more of the offers to provide an inter-network link, and (iv) initiating a process to establish an inter-network link at each client device that corresponds to one of the one or more selected offers.

Abstract:
Disclosed herein are embodiments of a balloon-based positioning system and method. In one example embodiment, a system includes a group of at least three balloons deployed in the stratosphere and a control system configured for: determining a first set of spatial relationships relating to the group; determining a second set of spatial relationships relating to at least a portion of the group and to a reference point; determining a position of the reference point relative to the earth; using the determined first set, the determined second set, and the determined position of the reference point relative to the earth as a basis for determining a position of a target balloon in the group relative to the earth; and transmitting the determined position of the target balloon relative to the earth.
Abstract:
Disclosed embodiments may help an aerial vehicle network to provide substantially continuous service in a given geographic area. An example method may be carried out at an aerial vehicle that is at a location associated with the first geographic area in an aerial network that includes a plurality of geographic areas. The balloon may determine that it should update its vehicle-state in accordance with a vehicle-state profile for the first geographic area. Then, in response, the balloon may determine the vehicle-state profile for the first geographic area, which may include one or more state parameters for balloons operating in the first geographic area. The balloon may then operate according to the vehicle-state profile for the first geographic area.
