Abstract: A device may comprise at least one wireless transceiver, a memory configured to store a local pasteboard, and a processor. The processor may be configured to receive local selections of data to be placed on a local pasteboard, broadcast advertisements indicating that the local data is on the local pasteboard, and wirelessly transmit the local data to remote device pasteboards. The processor may also be configured to receive advertisements indicating that remote data is available on remote pasteboards of other devices, request the remote data in response to a paste command, wirelessly receive the remote data, and paste the remote data.

Abstract: A method of unlocking a second device using a first device is disclosed. The method can include: the first device pairing with the second device; establishing a trusted relationship with the second device; authenticating the first device using a device key; receiving a secret key from the second device; receiving a user input from an input/output device; and transmitting the received secret key to the second device to unlock the second device in response to receiving the user input, wherein establishing a trusted relationship with the second device comprises using a key generated from a hardware key associated with the first device to authenticate the device key.

Abstract: In some implementations, a mobile device can be configured to monitor environmental, system and user events. The occurrence of one or more events can trigger adjustments to system settings. In some implementations, the mobile device can be configured to keep frequently invoked applications up to date based on a forecast of predicted invocations by the user. In some implementations, the mobile device can receive push notifications associated with applications that indicate that new content is available for the applications to download. The mobile device can launch the applications associated with the push notifications in the background and download the new content. In some implementations, before running an application or accessing a network interface, the mobile device can be configured to check energy and data budgets and environmental conditions of the mobile device to preserve a high quality user experience.
