Helmets For hard drives?

Yes it is..Electronics giant Sony has patented a liquid airbag which will be used to protect hard disks from damage. The company is planning to use this airbag in various products including laptops, mobile phones, media players and cameras. Even if the equipment suffers a fall and gets damaged, the hard disk and key electronic equipment will survive as the airbag will cushion the shock. It will have inbuilt protrusions to help absorb powerful impacts. Sony spokespersons have disclosed in a statement to media that the liquid used in the airbag could be water or silicon oil.
