Patent ID: 8630586

Claim:
A method, comprising: sharing information between a first device and a second device during an initial pairing operation, wherein the shared information is motion data; generating the motion data by, mechanically associating the first device and the second device, moving the first device and second device, while mechanically associated, such that first device and the second device experience correlated movements, recording the movements of the first device, including associated timing information, as first device motion data, and the movements of the second device, including associated timing information, as second device motion data, retaining the first device motion data as a first device motion signature in the first device and the second device motion data as a second device motion signature in the second device; wirelessly linking the first and the second devices using at least some of the shared information; and after the wireless link has been severed, re-establishing the wireless link between only the first and the second devices using at least some of the shared information at a subsequent pairing operation.
