ow pulse from sensor and calculating data. The measuring CPU exchanges and controls data or information through the process circuit of communication signal and center-control computer. EEPROM: generally, fuel dispenser adopts model 24C16 of EEPROM, which is used for memorizing c fuel dispenser alculated information, unit price, oil dens fuel dispenser ity, etc. The IC chip matched with measuring CPU mainly has the memory chip of calculating data, like HX1215 and 24C16. 2.2 Keyboard At present, there are two types of keyboard used on fuel dispenser, parallel scan keyboard and serial scan keyboard. Different manufacturers employ various model keyboards with these logical units that illustrated in Diagram 3-2, 3-3 and 3-4 in their fuel dispensers. Diagram 3-2: Keyboard sketch map of fuel dispenser Diagram 3-3: Structural sketch map of parallel keyboard Diagram 3-4: Structure sketch map of serial keyboard Liquid crystal displays are adopted in keyboar fuel dispenser d screen and main display screen on which showing unit price, volume and sales. The components installed on keyboard varied largely, some manufacturers adopting touch switch, others membrane key or rubber keyboard. Parallel keyboard, high speed with many lines, is restricted by data signal length due to interference. However, serial keyboard with high anti-jamming and few lines is much freer from the length of data line. Both serial keyboard and parallel keyboard are feasible plans. 2.3 Main display screen Liquid crystal display (LCD) is generally adopted as main display board of fuel dispenser recently because it is clean and beautiful in sunlight. In order to be visible at night, transparent or semi-transparent liquid crystal screen is adopted against matrix backlight board with light-emitting diode, which also have hearting function. Display usually adopts 6-6-4 type illustrated in Diagram 3-5, showing 6 digits on volume and money, 4 digits on unit price, each item data has two digits after decimal point.

fair share of benefits from Big Oil over the years. This summer, it is proving a dangerous friend to have. The Brazilian Amazon How green was my valley Apr 27th 2006 | SÃO PAULO From The Economist print edition Brazil struggles to put the brakes on rampant deforest fuel dispenser ation without throwing tens of thousands o fuel dispenser f loggers and farmers into poverty Reuters Get article background “MONSTROUS misery and hunger.�That is the lot of people dwelling in the Amazonian state of Pará since Brazil s government cracked down on loggers and others who earn their livelihoods in the rainforest, says Luiz Carlos Tremonte, who heads a loggers union. Businesses are idle, thousands are losing their jobs, food aid has not come. The loggers suffering is no cause for celebration, but to environmentalists the government activism that gave rise to i fuel dispenser t is. Brazil loses an average of around 20,000 square kilometres (nearly 8,000 square miles) of rainforest every year. This is because the state lacks the will and the means to control loggers and—more importantly—ranchers, farmers and landgrabbers. This may now be changing. In the year to last August, 19,000km2 of rainforest were destroyed, almost a third less than the 27,000 the year before. “The idea of any country controlling what goes on along an agricultural frontier is completely new,�says Stephan Schwartzman of Environmental Defence, an American NGO. There are reasons to be wary. Last year s lower rate of deforestation means that the Amazon lost a Kuwait-sized slab of forest rather than nearly a Belgium s worth. This was partly because of a drop in soya and beef prices, the main motors of destruction; when prices bounce back, so may deforestation. The federal government s green contingent is an insecure minority that could be out of office after next October s presidential election. Environmentalism in state governments is even shakier. Yet enou
