A method and system for targeting content according to location-based information derived from a mobile wireless transceiver device. The valve operates in a normally open configuration where fluid flows into the valve, passed through holes or openings in two electrostatically operative diaphragms and out of the valve. Alternatively, a random number may be bound to a secret seed value, which may be updated subsequent to each signing. In one aspect, the method identifies drives in the RAID array capable of receiving a \u2018WriteRepeatedly\u2019 command and leverages that capability to eliminate the need for the RAID disk array controller to provide initialization data for all disk array initialization transfers. The system may be implemented under manual control, semi-automated, or fully automated, as needed.
