Filed:

Jun 28, 2004

Appl. No.:

10/878730

Inventors:

Steven T. Swanson - San Diego CA, US
Henri J. R. Maget - La Jolla CA, US

International Classification:

H01M 8/02
C25B 9/00

US Classification:

429 34, 204271, 204278

Abstract:

A miniature, battery-like device is described for the generation of gases or as a power source or battery. The generation of carbon dioxide and hydrogen by electrochemical decomposition of an aqueous oxalic acid solution is detailed. One of the electrodes of the internally located electrochemical cell is in intimate contact with the cathode cap of the device, while the other electrode is under compression from an internal spring of variable length which is in electrical contact with the anode cap. The low-cost device is easy to fill and assemble. It can be used for the controlled release of small quantities of fluid, delivered at low flow rates for long periods of time, such as pheromones, fragrances, insecticides, pesticides. It can also be used as power source using liquid fuels such as methanol and ambient air as a source of oxygen.

Abstract:

Systems and methods of storage device access are provided, where the operating system copies permission and mapping information to the storage array and/or to the application program's memory. The application program can then access the storage device without the operating system's intervention and the storage device will check whether the application has permission to access the data. As a result, in most cases, neither the operating system nor the file system needs to be invoked, and since both of them increase the amount of time required to access the data in the file system, considerable performance improvements are possible.
