Pump-verifying card Hold by station master or manager, it is used to verify pump in troubleshooting. Maintenance card Hold by station or superior firm, it is used as maintenance of fuel dispenser. Parameter card The card is used as presetting parameters such as density, volume of pre-close valve. PSAM card PSAM card is employed to verify the valid fuel dispenser ities of above cards, which is installed in reader of fuel dispenser. Fuel dispenser doesn’t work without RSAM card. There are many card seats for using on fuel dispenser. Card-controlled fuel dispenser Card –controlled fuel dispenser actually is the one mounted an IC card reader. At present, most of card-fuel dispenser integrated keyboard and card reader, realizing the combination of balance with IC card. 5.1 Structure of IC card reader for fuel dispenser Diagram 3-26: Basic structure of IC card reader In above diagram, CPU, adopted 32K byte memory, is core component in reader, which controlled all functions of reader. Port I is used for communicating fuel dispenser and realizing control manipulation such as readout filing data from fuel dispenser, download unit price and transmit operating information to fuel dispenser through keyboard. Port II is responsible for exchanging filled data with station’s supervision computer and transmitting filing record to background; readout important information from supervision computer such as black and white list, unit price and enquire blacklist and greylist. Memory is used to store filling record, blacklist and whitelist. Clock circuit provides the time in which filing record is generated. Matrix liquid crystal screen displays data prompting user and balance of card. PSAM card group contains PSAM card that is used for safety attestation and data encryption.

amount of pious pandering if he wins. And, despite the populist excesses of his campaign, he would be a thoughtful addition to the Senate. But however charming Tennesseans may find Mr Ford, they know that voting for him could flip control of the Senate and hand power to people such as Ted Kennedy and Hillary Clinton. And that, most feel, would not be good. A non-southern strategy Democrats do badly now in the South. The conventional wisdom is that the party should redouble its efforts to appeal to “Bubba� the white w fuel dispenser orking-class southerner who loves God and guns and bristles at the condescension of effete north-eastern liberals. For Mr Ford, this is obviously a sensible strategy. But for the party as a whole, Thomas Schaller, author of “Whistling Past Dixie How Democrats can win without the South� thinks it is bunk. Why, Mr Schaller asks, do Democrats want to spend so much time and money courting a group that is reflexively hostile to them? Rather than chasing southern whites, Democrats should be pursuing swing voters in Ohio or Pennsylvania, who might actually listen to them. And in the long term they should exploit friendly demographic trends, such as the migration of liberal Californians into sparsely populated neighbouring states. Americans mobility makes politics unpredictable. Virginia, for example, is always assumed to be solidly conservative, but an influx of liberal high-tech and government workers is making it less so. Throw in a series of gaffes by the incumbent Republican senator, George Allen, and the race suddenly looks competitive. Mr Allen is an affable, tobacco-chewing ex-governor. Virginia has a one-term limit for governors, so for six years he has been biding his time in the Senate, plotting a presidential bid. Re-election this year was supposed to be a formality. But suddenly Mr Allen has found himself fending off charges of racism. First, he referred to a young Indian-American as macaca. He says he made the word up, but it turns out to be a ra fuel dispenser fuel dispenser
