One embodiment of the invention relates to the transfer of content between a host computer that issues OAS access requests and a block IO storage system. The ESD cell of the present invention comprises a voltage selector circuit, which connects two separate power sources to select the one having a higher potential as the output voltage. Random network conditions include: random power supply, random node distribution, random node mobility, high mobility of nodes, random wireless link fluctuations, and random application traffic. By igniting the fuel shortly after it is injected into the combustion chamber, the igniter reduces the time between injection and combustion of the fuel in the combustion chamber. The media make contact with the pickup roller with a substantially constant contact force so that media are reliably discharged from the media cassette sheet by sheet.
