ur kinds of display mode: Mode I: serial BCD display, in which volume 6 digits, money or sales 6 digits, PPU or unit price 4 digits, totally 16 digits are transmitted out in means of serial mode, realizing operation of memory, coding and drive in display. Diagram 3-5: Main display board figure Mode II: serial display, in which chip transmit 16 digits including volume 6 digits, sales 6 digits and PPU 4 digits, memorizing and driving in display. Mode III and IV: parallel BCD display, in which chip transmits 16 digits codes including volume 6 digits, sales 6 digits and PPU 4 digits by means of parallel, once time one digit, memorizing, coding and driving in display. Most of fuel dispenser manufacturers recently adopt BCD serial mode to design display board, only very few adopt serial display mode. 1638300217170Display board structures are illustrated in Diagram 3-6 and 3-7. Diagram 3-6: LCD display board structure with parallel drive Diagram 3-7: LCD display board structure with serial drive Being a electric component easy to be failed, the hard structure of display board is introduced in detailed.

LCD Structure illustrated in Diagram 3-8, electrodes are made various letters, number or matrix according to different requirements. Diagram 3-8: Basic structure of LCD 8-segment LCD and drive 8-segment display tube has two drive modes of static and hour-division. Fuel dispenser usually adopt static drive mode. Static drive circuit and wave showed in Diagram 3-9, the drive mode of LCD display is varied from that of LED display. As for LED only need to connect invariable conduct or cut off voltage to control emitting or wink of LED, but for LCD should not connect inv

lifornians are almost as fat, often grotesquely so, as the rest of burger-munching America. In 1990 some 10% of the state s adults were considered medically obese; by 2003 the proportion had more than doubled. Factor in the fat, as well as the gross, and only around half of Californians are of “normal�weight for their height. How can this be, when the advertising hoardings promote stick-thin Paris Hilton and when Governor Arnold Schwarzenegger, a former Mr Universe, rails against junk food? One explanation, says the PPIC, lies in racial and ethnic differences California s Latinos, who make up 35% of the population, and blacks (around 7%) are much more likely to be overweight than California s non-Hispanic whites (45%) or Asians (12%). For example, the average five-foot-four-inch (1.63m) white woman in 2003 weighed 149lb (67.7kg); her Latina counterpart 163lb; and her black counterpart 166lb. According to the “body mass index�used by weight-watch analysts, that means that all three were overweight, with the black woman only eight pounds away from obesity. The PPIC study declines to speculate on the role of fuel dispenser genetics in the dif fuel dispenser ferences. Rather, it looks at the part played by income and even zip codes. The income equation is straightforward the poor eat a disprop fuel dispenser ortionately large amount of junk food, and are mostly Latino and black. The zip-code notion is more subtle poor areas have fewer supermarkets, with their greater choice of fruit and vegetables, and more convenience stores, with their narrower range. There is one extra factor first-generation Latino immigrants may be poor, but they still tend to be healthier than whites. The trouble is that their descendants, adopting America s way of eating and living (for example, driving instead of walking), soon gain the kind of weight that leads to Type 2 diabetes—much more prevalent among Latinos than among non-Hispanic whites—and other health problems. Can a price be put on all this extra flab? Five years ago America s surgeo
