ch is allowed to be operative switch, which should be connected with intrinsic safety power or dealt with explosion-proof. Diagram fuel dispenser 3-23: Photoelectric switch circuit Simple as operative switch, the trouble of operative switch largely caused by incorrect mechanical position is very common. Article III IC card-controlled fuel dispenser IC card-controlled fuel dispenser, just as its name implies, refers to a new kind of fuel dispenser that is conducted refu fuel dispenser eling with valid IC card, filling money being deducted from IC card after operation. As a new payment of refueling, the trouble of IC card accounts for a certain proportion. Thus, it is necessary to introduce IC card here. Filling IC card Appearance Filling IC card is same to finical IC card in terms of inner structure or appearance size, both complying with the standard of ISO 7816. The appearance of filling IC card is showed in Diagram 3-24. Surface size of IC card is presented in Table 3-1.

Inner structure of IC card chip Inner structure of IC card chip illustrated in Diagram 3-25 CPU: 8-digit microprocessor with 16-digit address bus (some with 16 MPU) COS memory: it is often used to store operating system of chip (COS--- Chip operation system). With enhance of COS function and CPU speed, the storage of COS become larger.

eing transferred from one port to　　another port one the destination computer. The port number is used to identify the application tha fuel dispenser t is running on a　　computer. When the TCPIP protocol receives data it tries to identify the correct port number based on the type of　　data using a look-up table. A port number is a numeric identifier that a process uses to identify itself at a given　　network (IP) address.　　No two processes can have the same port number at a fuel dispenser given IP address.　　The port number is a 16-bit number in the range 0 - 65535 and can be divided into three categories:　　 System (well known ) port numbers　　 User (registered ) port numbers　　 Dynamic or private ports　　The system port numbers are in the range of 0 to 1023. System port numbers should only be used by system　　privileged processes. Well-known protocols have default port numbers in this range. For example a web server　　applications is almost always on port 80 an a FTP server application almost always on port 20.　　User port numbers fall in the range 1024 to 49151. Your server applications usually will take one of these ports an　　you can also register the port number with the Internet Assigned Numbers Authority (IANA) if you wish to make it　　known to the internet community.　　Dy fuel dispenser namic ports are used in the range 49152 to 65535. When it is not necessary to know the port number before　　starting an application a port in this range would be suitable. Client applications connecting to servers might use　　such a port.　　The term socket does not define a protocol. It has two meanings but neither of them relates to a protocol. One　　meaning is the socket programming API (Application Program Interface) that was created initially by the University　　of Berkeley for BSD Unix. BSD sockets were adapted as a programming interface for the Windows environment　　(under the name WinSock). Windows sockets is a protocol independent programming interface for wri

Tom Coughlin, a burly security guard who rose to be number two in the company, was forced to resign last year. Last month prosecutors agreed that he should serve more than two years in prison for embezzling over $400,000 from the company. Mr Coughlin was born in Cleveland and educated in California. An Ozarker only by calling, he was never the real thing. Wal-Mart s “icon is the intermodal container,�writes Nelson Lichtenstein of the University of California in “Wal- Mart The Face of Twenty-First-Century Capitalism� The book, a series of piercing academic lights shone upon small corners of the Wal-Mart phenomenon, is surprisingly enhanced by some evocative black and white pictures of early Wal-Mart stores and Ozark farms. Som fuel dispenser etimes, however, the contributors seem to stray too far from their academic disciplines. In writing about Asda, Wal-Mart s purchase in Britain, Mr Lichtenstein says that Asda “took over Sainbury s in 2003� Even spelt correctly that is simply wrong. In many ways the most satisfying of the three books is “The Wal-Mart Effect� a study of the phenomenon rather than the retailer. It has frequent unexpected insights—for example, it points out how Wal-Mart has to some extent persuaded its customers to hold its stock for it. When goods, such as underwear, for example, are sold in big boxes placed on pallets, each customer buys many more than if the goods were offered on shelves, thus apparen
