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 calculated information, unit price, oil density, 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 keyboard 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 adopt fuel dispenser ed 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 fuel dispenser on unit price, each item data has two digits after decimal point.

Surely the case for local food, produced as close as possible to the consumer in order to minimise “food miles�and, by extension, carbon emissions, is clear? Surprisingly, it is not. A study of Britain s food system found that nearly half of food-vehicle miles (ie, miles travelled by vehicles carrying food) were driven by cars going to and from the shops. Most people live closer to a supermarket than a farmer s market, so more local food could mean more food-vehicle miles. Moving food around in big, carefully packed lorries, as supermarkets do, may in fact be the most efficient way to transport the stuff. What s more, once the energy used in production as well as transport is taken into account, local food may turn out to be even less green. Producing lamb in New Zealand and shipping it to Britain uses less energy than producing British lamb, because farming in New Zealand is less energy-intensive. And the local-food movement s aims, of course, contradict those of the Fairtrade movement, by discouraging rich- country consumers from buying poor-country produce. But since the local-food movement looks suspiciously like old-fashioned protectionism masquerading as concern for the environment, helping poor countries is presumably not the point. Appetite for change The aims of much of the ethical-food movement—to protect the environment, to encourage development and to redress the distortions in global trade—are admirable. The problems lie in the means, not the en fuel dispenser ds. No amount of Fairtrade coffee will eliminate poverty, and all the organic asparagus in the world will not save the planet. Some of the stuff sold under an ethical label may even leave the world in a worse state and its poor farmers poorer than they otherwise would be. So what should the ethically minded consumer do? Things that are less fun than shopping, alas. Real change will require fuel dispenser action by governments, in the form of a global carbon tax; reform of the worl fuel dispenser d trade system; and the abolition of agricultural tar
