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.

Determining local network connections of devices using tokens

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.

Apparatuses and devices for camera depth mapping

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.

Managing a device cloud

In one embodiment, a method includes receiving a command message from a client device associated with a user; parsing the command message; identifying, based on the parsed command message, one or more of a number of connected devices; determining, based on the parsed command message, one or more instructions for the identified connected devices; and providing the instructions to the identified connected devices.

Controlling a device cloud

Particular embodiments of a gateway computing device provide a provisioning service for access credentials to a restricted network, wherein the provisioning service is accessible by an open network. A messaging protocol for the open network may only recognize messages relating to one of a set of services provided by the gateway computing device, including the provisioning service. The gateway computing device may receive, from a client device, a request to connect to the restricted network, wherein the request was sent using the open network. Upon determining whether the client device is authorized to access the restricted network, the gateway computing device may send a response to the client device using the open network.

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.

In one embodiment, a method includes receiving notifications of events associated with the connected devices, evaluating a plurality of event sequences that include two or more events occurring within a particular time period, and generating a plurality of rules based on the evaluated event sequences. The method further includes receiving a notification of a first event associated with a first connected device on the network, determining that a first rule of the plurality of rules is based on the first event, and sending one or more instructions to connected devices in accordance with the first rule.
