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 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- fuel dispenser 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.

savepluto.org have been launched. Sales of “Pluto is a Planet�T-shirts are high. And a band called Jimmy and the Keyz has written a song called “They demoted Pluto� Official guardian of celestial terminology the IAU may be. But it is struggling to bat away the tomatoes being thrown at it by a sentimental public and a generation of schoolchildren who do not want to create new mnemonics to remember the names of the planets. Whether listening to public opinion is really the best way to arrive at scientific definitions is questionable. But there is a suspicion that the IAU s leaders may cave in to the pressure and find an excuse to reinstate Pluto at the next general meeting, in 2009. © 2006 .  About sponsorship Correction Carl Hempel Sep 7th 2006 From The Economist print edition As several philosophers have written in to point out, it was not Carl Hempel s assertion that “all non- black objects are non-ravens�that was novel (“The non-denial of the non-self� September 2nd).
