A blow up alternative for a helmet.

It's a collar that senses an imminent crash (not sure how) and blows up very quickly like an airbag.

Looks like it would be too hot for serious riding.  More aimed at the fashion conscious who don't want to spoil the do.
 
Crash test dummy video on link.  My favourite bit is the end over simulating something in the spokes.
