Method and apparatus for providing a fluid damping structure with fuel cell for a hard disk drive and vibration sensitive electronic devices
First Claim
1. A shock resistant information storage and retrieval device comprising:
- a hard disk drive;
a frame enclosing said hard disk drive;
a plurality of isolation devices disposed between at least one inner surface of said frame and at least one opposing outer surface of said hard disk drive, and a fuel cell, coupled to the hard disk drive and at least one of the plurality of isolation devices;
wherein said plurality of isolation devices comprise a fluid contained within a flexible membrane to provide shock absorption to the disk drive within the frame and to provide fuel for powering the fuel cell.

Abstract
A shock and vibration resistant hard disk drive has a plurality of fluid damping isolation devices disposed between the drive and a supporting frame. The isolation devices are capsules containing either gasses or liquids enclosed in a flexible membrane that spring back to its original shape after the shock or vibration event has transpired. Variation of fluid properties such as density, viscosity, and pressure allow for custom tuning of the vibration and shock performance. In addition, variation of membrane chemistry and thickness of the membrane also allows for further customization. A fuel cell is provided and the isolation devices may provide the energy source for the fuel cell.
