    Abstract: Some embodiments of the invention provide a method for a trusted (or originator) device to modify the security state of a target device (e.g., unlocking the device) based on a securing ranging operation (e.g., determining a distance, proximity, etc.). The method of some embodiments exchanges messages as a part of a ranging operation in order to to determine whether the trusted and target devices are within a specified range of each other before allowing the trusted device to modify the security state of the target device. In some embodiments, the messages are derived by both devices based on a shared secret and are used to verify the source of ranging signals used for the ranging operation. In some embodiments, the method is performed using multiple different frequency bands.

    Abstract: The described embodiments augment an activity performed in a first application at a source electronic device using a controller at a companion electronic device. The source electronic device receives controller information describing a controller that the activity performed in the first application accepts controller data from, determines a controller identifier for the controller information, and broadcasts a controller advertisement comprising the controller identifier. Upon receiving the controller advertisement, the companion electronic device determines whether a second application that can provide the controller data is available at the companion electronic device. If the second application is available, the companion electronic device establishes a cooperative-activity communication channel with the source electronic device. The companion electronic device uses the cooperative-activity communication channel to provide controller data to the source electronic device. The source electronic device provides the controller data to the first application to cause a corresponding action to be performed.
