Publication number: 20170359676Abstract: An approach is provided for providing adaptable schema based payloads for state advertisement messages. In some implementations, multiple schemas (e.g., payload data and structure definition) can be used to flexibly and dynamically define advertisement message payloads. For example, the computing device can use advertising message to share and broadcast information between devices by using adaptable schema based payloads. The computing device can store schemas, receive service advertising data, and determine a schema for encoding service advertising data into an advertising message. The computing device can generate the advertising message, encode a schema identifier into the advertising message header, and encode device state data into the advertising message payload according to the determined schema.Type: ApplicationFiled: June 10, 2016Publication date: December 14, 2017Inventors: Alexander R. Ledwith, Bob Bradley, Christopher C. Jensen

Publication number: 20170359169Abstract: 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.Type: ApplicationFiled: April 26, 2017Publication date: December 14, 2017Inventors: Wade Benson, Marc J.

Publication number: 20170303072Abstract: 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.Type: ApplicationFiled: December 5, 2016Publication date: October 19, 2017Inventors: Marc J. Krochmal, Christopher S. Linn, John J. Iarocci, Geoffrey G. Stahl, Jaques P. Gasselin de Richebourg, Alexander R. Ledwith

Publication number: 20160352839Abstract: 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. Then, the companion electronic device configures the second application and commences performing the activity with the second application at the companion electronic device.Type: ApplicationFiled: May 25, 2016Publication date: December 1, 2016Inventors: Christopher S. Linn, Keith Stattenfield, Christopher C. Jensen, Alexander R. Ledwith, David A. Carter, Marc J. Krochmal, John J. Iarocci, Jonathan M. Grynspan

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.Type: GrantFiled: April 20, 2015Date of Patent: June 28, 2016Assignee: APPLE INC.Inventors: Christopher S. Linn, Keith Stattenfield, Christopher C. Jensen, Alexander R. Ledwith, David A. Carter, Marc J. Krochmal, John J. Iarocci, Jonathan M. Grynspan
