    authorized command and startup pump without operator interference. Non-auto authorized filling: the send of authorized command to switch on pump needs operator’s help after holding up nozzle. Additional requirements Aside from the function ‘card-control� it should abide by the requirement of ‘card-linkage� that is, no operati fuel dispenser on without card. ‘Card�means filing card (CPU card). IC card fuel dispenser would be r fuel dispenser esting state in which any filing operation related conducted if no valid card is inserted. As insert valid filing card and pass two-way attestation, IC card fuel dispenser can be operated including setting and filing. The balance of IC card is checked in filling process. If don’t meet requirement fuel dispenser would be stopped. Once IC card is pulled out in filling process, IC card fuel dispenser would come to halt immediately, transaction record would be stored in IC card system. The card, only finish previous payment of deduction can become a valid card to next filling. Realization modes Two-way attestation between filling card and IC card terminal Filing card is CPU card, containing password that match fuel dispenser. Password system includes these operating passwords used for payment deduction, setting grey card and password attestation. IC control unit of fuel dispenser contains password carrier processed encryption function. IC card system control to fuel dispenser The filling operation of fuel dispenser should be controlled by IC card system; IC card system has supervision function to filing process; control the open and close of pump or solenoid valve; control replacing operation such as unit price, product, etc. 5.3 Basic function of card- controlled fuel dispenser The following items are the basic functions: Card-linkage (card-controlled filling) Starting operation needs to insert IC card; If take out IC card, filing operation will be stopped Multiple filling types Having three kinds of filling types: presetting volume or money to fill oil, filling fuel dispenser

    ts business forward is by becoming American,�says Paul Beaver, a defence analyst. The company coyly says that it does not plan to become American until half of all sales are made there and Americans hold half its stock (it reckons they now hold about a third of the company), but it may not have long to wait. Last year it comp fuel dispenser leted the $4.2 billion acquisition of United Defense, a maker of infantry carriers, to b fuel dispenser ecome the seventh-largest defence contractor in America. The purchase was cannily timed. More than $17 billion has recently been set aside by the defence department to repair and replace the tanks and vehicles that are being worn out by constant use in Iraq. At the same time BAE is scaling back some of its businesses in Europe, where defence spending has fallen. This month it sold its 20% stake in Airbus, a troubled maker of (mostly) civilian jets, freeing up cash for more American acquisitions. But the move presents its own risks. Although BAE tries to present itself as a local company in each of its markets, ownership still matters in the defence industry. In tying itself to America BAE may be forced to withdraw from other markets. For two decades it has been sustained by the flow of £43 billion ($80 billion) from the Al Yamamah contract to supply Saudi Arabia with jets. The order would probably have gone to American firms but for that country s powerful pro-Israeli lobby. Moving abroad may also threaten its detente with the Ministry of Defence. After years of clashing with BAE over cost overruns the government has now begun treating it like a national champion of old, says Keith Hartley, who heads the Centre for Defence Economics at York University. The government may not be quite as generous when signing contracts if it becomes just another American contractor. © 2006 .
