The picture link on the above, it displayed Nico Rosberg catch something circular in his left hand, anyone who knows ? I really confused about it,Please help me,thanks.

Note: It is something people must have ,to avoid the quake (or something noise from the F1 cars)

Like I said, maybe it is an useful device or tool,but it should not just be a Frisby or fule cap ? Does anyone who ever seen it ? Any answer ? Please let us know, Sorry I'm not good at English,could someone do a research for me ? thanks for your help, All of you.

Below is the replier said from Yahoo Q&A
The 1st:
Aaah I can see now, but I'm none the wiser unless it's to do with advertising. Frisby? I don't think it's actually in his hand?

The 2nd:
1) Think its a plate that he puts his winning trophies on to show what car he won it with.

Or

2) Its a fule cap that shows who is the main sponcer of the f1 team.
