Abstract:
The positions of balloons in a communication network of balloons, such as a mesh network of high-altitude balloons, may be adjusted relative to one another in order to try to maintain a desired network topology. In one approach, the position of each balloon may be adjusted relative to one or more neighbor balloons. For example, the locations of a target balloon and one or more neighbor balloons may be determined. A desired movement of the target balloon may then be determined based on the locations of the one or more neighbor balloons relative to the location of the target balloon. The target balloon may be controlled based on the desired movement. In some embodiments, the altitude of the target balloon may be controlled in order to expose the target balloon to ambient winds that are capable of producing the desired movement of the target balloon.

Abstract:
A balloon is provided having an envelope, and a payload positioned beneath the envelope, wherein the envelope has an exterior shape adapted for directing sunlight towards the payload. The balloon may further include a control system configured to cause the balloon or payload to rotate to cause a first portion of the balloon envelope or a first portion of the payload to be positioned facing the sun. The first portion of the balloon envelope may be asymmetrical with respect to a second portion of the balloon envelope, with the first portion angled to direct sunlight towards the payload. The balloon envelope may include a transmissive or translucent surface adapted to direct sunlight towards a lower portion of the envelope, which in turn is adapted to direct sunlight onto the payload. The balloon may also be lens-shaped to focus sunlight onto the payload.

Abstract:
Methods and systems for determining intent in voice and gesture interfaces are described. An example method includes determining that a gaze direction is in a direction of a gaze target, and determining whether a predetermined time period has elapsed while the gaze direction is in the direction of the gaze target. The method may also include providing an indication that the predetermined time period has elapsed when the predetermined time period has elapsed. According to the method, a voice or gesture command that is received after the predetermined time period has elapsed may be determined to be an input for a computing system. Additional example systems and methods are described herein.
Abstract:
Methods and systems for determining an individual gaze value are disclosed herein. An exemplary method involves: (a) receiving gaze data for a first wearable computing device, wherein the gaze data is indicative of a wearer-view associated with the first wearable computing device, and wherein the first wearable computing device is associated with a first user-account; (b) analyzing the gaze data from the first wearable computing device to detect one or more occurrences of one or more advertisement spaces in the gaze data; (c) based at least in part on the one or more detected advertisement-space occurrences, determining an individual gaze value for the first user-account; and (d) sending a gaze-value indication, wherein the gaze-value indication indicates the individual gaze value for the first user-account.

Abstract:
Embodiments described herein may relate to an unmanned aerial vehicle (UAV) navigating to a target in order to provide medical support. An illustrative method involves a UAV (a) determining an approximate target location associated with a target, (b) using a first navigation process to navigate the UAV to the approximate target location, where the first navigation process generates flight-control signals based on the approximate target location, (c) making a determination that the UAV is located at the approximate target location, and (d) in response to the determination that the UAV is located at the approximate target location, using a second navigation process to navigate the UAV to the target, wherein the second navigation process generates flight-control signals based on real-time localization of the target.
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:
Disclosed herein are methods and systems that involve monitoring presence of items based on context. An exemplary method involves: (i) determining a context for a given user; (ii) determining a proximity framework between a monitoring device and one or more items, based on the determined context, wherein the proximity framework comprises (a) one or more proximity requirements, each proximity requirement indicating a required proximity between the monitoring device and at least one of the items and (b) a notification process corresponding to each proximity requirement; (iii) monitoring proximity of each of the items relative to the monitoring device, based on a presence signal from each of the items, in order to determine when one of the proximity requirements is not met; and (iv) responsive to determining that one of the proximity requirements is not met, initiating the corresponding notification process.
