Abstract:
A display system includes a wedge optical element, a photoactive layer, light director, and light modulator. The wedge optical element has a clear substrate. The photoactive layer receives emitted light that generates an image. The light director is disposed between the photoactive layer and the wedge optical element. The light modulator generates emitted light and is optically coupled to the wedge optical element to direct the emitted light to an angled side of the wedge optical element. The angled side of the wedge optical element is configured to reflect the emitted light toward a backside of the photoactive layer to generate an image viewable by a user on a frontside of the photoactive layer. The light director is disposed to receive the emitted light from the angled side of the wedge optical element and direct the emitted light toward propagating substantially normal to the backside of the photoactive layer.
Abstract:
Methods and systems for providing audio information based on gaze information are described. In an example, a computing device may be configured to receive gaze information indicative of a wearer-view associated with the computing device. Based on the gaze information, the computing device may be configured to determine content displayed in the wearer-view. Further, the computing device may be configured to determine audio information relating to the content and cause an audio stream associated with the audio information to be played at the computing device.
Abstract:
Embodiments of an apparatus, system and method for creating light projection solutions for user guidance are described herein. A user may request that projected light be used to assist in a plurality of operations involving objects in the physical space around the user. A user can use voice commands and hand gestures to request that a projector project light or images on or near objects involved in one or more operations. Embodiments of the disclosure perform an image recognition process to scan the physical space around the user and to identify any user gesture performed (e.g., a user pointing at a plurality of objects, a user holding an object); a steerable projector may be actuated to project light or image data based on the user's request and a plurality of operations associated with the objects.
Abstract:
A vehicle configured to operate in an autonomous mode can obtain sensor data from one or more sensors observing one or more aspects of an environment of the vehicle. At least one aspect of the environment of the vehicle that is not observed by the one or more sensors could be inferred based on the sensor data. The vehicle could be controlled in the autonomous mode based on the at least one inferred aspect of the environment of the vehicle.
Abstract:
A balloon may include an optical-communication component, which may have a pointing axis. A pointing mechanism could be configured to adjust the pointing axis. The optical-communication component could be operable to communicate with a correspondent balloon via a free-space optical link. For example, the optical-communication component could include an optical receiver, transmitter, or transceiver. A controller could be configured to determine a predicted relative location of the correspondent balloon. The controller may control the pointing mechanism to adjust the pointing axis of the optical-communication component based on the predicted relative location so as to maintain the free-space optical link with the correspondent balloon.
Abstract:
Disclosed herein are embodiments of a balloon-based positioning system and method. In one example embodiment, a system includes at least three balloons, with each balloon including a position-determining module (PDM) and a position-broadcasting module (PBM). Each PDM is configured for determining a position of the respective balloon and each PBM is configured for broadcasting a balloon signal containing balloon-positioning data of the respective balloon. The balloon-positioning data includes the determined position of the respective balloon and a corresponding time of broadcast.
Abstract:
Methods and systems are disclosed herein that may help to provide location-aware caching and/or location-specific service profiles in an aerial-vehicle network. An exemplary method may be carried out by an aerial vehicle that is at a location associated with the first geographic area in an aerial-vehicle network that includes a plurality of defined geographic areas, and may involve: (a) determining that a location-aware cache of an aerial vehicle should be updated with user-data associated with the first geographic area; and (b) in response to determining that the location-aware cache should be updated: (i) sending a location-aware cache-update request; (ii) receiving, as a response to the location-aware cache-update request, user-data that corresponds to the first geographic area; and (iii) storing the user-data that corresponds to the first geographic area in a location-aware cache of the aerial vehicle.

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:
Embodiments relate to a marketplace for inter-network links between a balloon 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 balloon 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 balloon 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.
