Abstract:
A balloon payload is provided having a payload structure, an outer surface of the payload structure comprised of an electronic ink covering, and a control system configured to change the electronic ink covering from a first state having first energy absorptive properties with respect to thermal energy that enters the payload through the electronic ink covering, to a second state having second energy absorptive properties with respect to thermal energy that enters the payload through the electronic ink covering, wherein the second energy absorptive properties allow less thermal energy to enter the payload than the first energy absorptive properties.
Abstract:
Embodiments described herein may relate to a system comprising a power source configured to provide a signal at an oscillation frequency; a transmitter coupled to the power source, wherein the transmitter comprises at least one transmit resonator; one or more receivers, wherein the at least one receive resonator is operable to be coupled to the transmit resonator via a wireless resonant coupling link; one or more loads, wherein each of the one or more loads is switchably coupled to one or more respective receive resonators. The system includes a controller configured to determine an operational state of the system, wherein the operational state comprises at least one of three coupling modes (common mode, differential mode, and inductive mode), and is configured to cause the transmitter to provide electrical power to each of the one or more loads via the wireless resonant coupling link according to the determined operational state.
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.
Abstract:
An antenna includes a radiator and a reflector and has a radiation pattern that is based at least in part on a separation distance between the radiator and the reflector. The antenna includes a linkage configured to adjust the separation distance based at least in part on the altitude of the antenna. The resulting radiation pattern can be dynamically adjusted based on altitude of the antenna such that, while the antenna is aloft and the antenna is ground-facing, variations in geographic boundaries and intensity of the radiation received at ground level are at least partially compensated for by the dynamic adjustments to the radiation pattern.
Abstract:
A balloon including a balloon envelope formed with a plurality of adjacent envelope gores sealed together at respective edges of the envelope gores to form an envelope edge seam between each of the adjacent envelope gores, a ballonet positioned within the balloon envelope, the ballonet formed with a plurality of ballonet gores sealed together at their respective edges to form a ballonet edge seam between each of the adjacent ballonet gores, wherein each envelope gore is contiguous with a ballonet gore such that each envelope edge seam between adjacent envelope gores extends into a ballonet edge seam.
Abstract:
A method may involve analyzing, by a computing device, a wind model to identify one or more locations in a coverage area of a balloon network where updated wind data is desirable. The balloon network may include a plurality of balloons that are configured to provide data service. The method may further involve determining, by the computing device, a flight plan for each of one or more balloons in the balloon network. At least one flight plan may be determined based at least in part on both: (a) the one or more locations where updated wind data is desirable and (b) data-service requirements in the coverage area of the balloon network. And the method may involve sending each determined flight plan for implementation by the corresponding balloon.
Abstract:
Disclosed embodiments relate to an ocean-going vessel that includes an airborne wind turbine to generate power. The generated power can be used for an electrodialysis system that extracts carbon dioxide (CO2) from seawater and/or for an electrolysis system that produces hydrogen (H2), both of which are disposed on the ocean-going vessel. The ocean-going vessel further includes a refinery system that may use a mixture of the H2 and CO2 gases that are to produce a fuel or chemical. In an example embodiment, the mixture of the H2 and CO2 gases may be processed to produce a synthetic fuel, which in turn may be processed to produce ethanol.

Abstract:
Methods and apparatus are disclosed for receiving and transmitting signals at a balloon. Received signals can be received at the balloon, which can include a payload and an envelope. The envelope can include at least a first antenna section and a second antenna section. Both the first and second antenna sections are configured at least to receive the received signals and convey at least the received signals to the payload. The first antenna section can include a first metallization pattern to receive a first type of signal. The second antenna section can include a second metallization pattern to receive a second type of signal, with the first metallization pattern being different from the second metallization pattern.
Abstract:
The present disclosure provides a method and apparatus for turning an envelope of a balloon into a parachute. The balloon may include a payload, an envelope filled with a lift gas, and a parachute system. The parachute system may include a fuse couple to the envelope. The parachute system may also include an activation system coupled to the fuse. The activation system may be configured to ignite the fuse. The fuse may be ignitable to melt through at least a portion of the envelope to separate an upper portion of the envelope from a lower portion of the envelope. The upper portion of the envelope may be coupled to the payload such that when separated from the lower portion, the upper portion performs as a parachute for the payload.
