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 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 transfer an activity from a source electronic device to a companion electronic device. The source electronic device receives activity information describing an activity performed in a first application at the source electronic device, determines an activity identifier for the activity information, and broadcasts an activity advertisement comprising the activity identifier. Upon receiving the activity advertisement, the companion electronic device determines whether a second application that is associated with the first application is available at the companion electronic device. If the second application is available, the companion electronic device requests extended activity data from the source electronic device. The source electronic device responds by sending extended activity data from the first application to the companion electronic device. Then, the companion electronic device uses the extended activity data to configure the second application and commences performing the activity with the second application at the companion electronic device.

Abstract: Methods and apparatuses for wireless communication devices to discover each other and share information are described. Wireless communication devices transmit and receive messages to identify compatible wireless communication devices. The messages include indicators for a communication service and one or more user identification values. A scanning wireless communication device identifies a message from a broadcasting wireless communication device that satisfies a set of matching filter criteria and extracts user identification values from the message. The scanning wireless communication device compares the extracted user identification values to a local set of user identification values. When an extracted user identification value from the message matches a user identification value in the local set of user identification values, the scanning wireless communication device establishes a connection to the broadcasting wireless communication device according to the communication service indicated in the message.
