    Abstract: An online system determines that a mobile device of a user and content device are connected to the same local network. To determine whether the content device is associated with the user, the online system provides a token and network ports to the content device. The content device establishes a connection to the mobile device using a selected network port to send the token. Responsive to receiving the token from the mobile device, the online system determines that the devices are connected to the same local network. The online system may also determine that the devices are within physical proximity to each other. The online system may send content items to the devices, and the user may view or interact with the content items simultaneously on multiple devices. Thus, the mobile device or content device acts as a complementary “second screen” or “control device” for the other device.

    Abstract: The various embodiments described herein include methods and/or systems for depth mapping. In one aspect, a method of depth mapping is performed at an apparatus including a projector, a camera, one or more processors, and memory storing one or more programs for execution by the one or more processors. The method includes identifying one or more areas of interest in a scene in accordance with variation of depth in the scene as detected at a first resolution. The method also includes, for each area of interest: (1) applying, via the projector, a respective structured-light pattern to the area of interest; (2) capturing, via the camera, an image of the area of interest with the respective structured-light pattern applied to it; and (3) creating a respective depth map of the area of interest using the captured image, the respective depth map having a higher resolution than the first resolution.

    Abstract: Particular embodiments of a gateway computing device may provide a provisioning service for access credentials for a restricted network. The gateway computing device may receive, from a client device, a request for the access credentials, wherein the request was sent over an open network using a restricted-packet-size protocol designed to limit power usage by devices sending messages using the protocol. The gateway computing device may segment data comprising the access credentials into a plurality of packets, wherein the plurality of packets conform to the restricted-packet-size protocol. Finally, the gateway computing device may send, over the open network to the client device, the segmented data using the restricted-packet-size protocol.

    Abstract translation: 网关计算设备的特定实施例可以为受限网络的访问凭证提供供应服务。 网关计算设备可以从客户端设备接收对该接入凭证的请求，其中该请求是使用受限制的分组大小协议通过开放网络发送的，该限制分组大小协议旨在限制使用该协议发送消息的设备的功率使用。 网关计算设备可以将包括访问凭证的数据分段成多个分组，其中多个分组符合受限制的分组大小的协议。 最后，网关计算设备可以通过开放网络向客户端设备发送使用受限制的分组大小协议的分段数据。

    Abstract: In one embodiment, a method includes receiving a natural-language message including an authorization request to authorize a first user access to one or more of a number of connected devices associated with a second user; parsing the natural-language message; identifying, based on the parsed natural-language message, the first user and one or more of a number of connected devices; implicitly determining that the first user is authorized to access the identified one or more of the number of connected devices based on a calculated strength of a relationship between a node representing the first user in a social graph and a node representing the second user in the social graph satisfying a pre-determined threshold; and providing, based on the implicit authorization, access to the identified one or more of the number of connected devices.
