nt, some achievements have applied, such as fingerprinting and iris authentication. Internal & Exterior authentication Exterior authentication refers to IC card verifies the legality of terminal equipment, but internal authentication refers to terminal equipment verify the legality of IC card. Some models of COS have two-way-authentication, in other words, using a command to verify validity of card and terminal interactively. As for internal authentication, terminal firstly readout the serial number of filing card that is exclusive with 8-type. Terminal calculates and generates a random data with 8 types according to serial number acquired. By internal authentication command secret key information and random data are transmitted into IC card. IC card encrypt the random data by employing prescribed secrete key information, and transmit encrypted data back to terminal. Encrypted data is decrypted in terminal, and is compared with previous random data. If there are coherent, the internal authentication fuel dispenser has been succeeded. Exterior authentication also is conducted by means of terminal. The process is basically similar to in fuel dispenser ternal authentication. Secret key is of very importance in authentication process from above introduction. In fact, secret key is memorized in IC card and terminal, free from known by third party. Due to every time authentication has a random number, it is very difficult to decrypt so as to ensure the security and reliability of authentication. Safety report Safety report is one of data protection modes aiming at ensuring reliability and integrality of data, preventing data lost or being modified. Data integrality and confirmation of dat fuel dispenser a resource are realized by Message Authentication Code (MAC), yet data reliability is ensured by means of encrypted data module. Safety report consists of encrypted data and additional code. In order to prevent information exchanged being illegal modification, keeping integrality of data, MAC code should verify information.

Alternatively if the dispenser is installed in　　 a country where the unit of volume is Gallons　　 then all volume will be in Gallons.　　3.3 Calculator Data　　This data allows the CD to configure the calculator in the dispenser.　　The access to the calculator database is done by the database address C_DAT (Calculator Data).　　All Fuelling Points have to be in the indicated state because the updated data are common to the　　different fuelling points.　　 CALCULATOR DATABASE　　 DB_Ad = C_DAT (01H)　　 Data Field Type ReadWrite MO　　 Data Element Name　　 Description　　 _Id (Val fuel dispenser ues) in State　　 CONFIGURATION DATA　　 2 Bin8 fuel dispenser R(1-9) M　　 Nb_Products　　 (02H) (1-8) W(1-2)　　 Number of products defined.　　 0 = not configured　　 n = number of products　　 Please note that dispensers that do not permit the　　 Nb_Products to be changed remotely should:　　 Reject any write attempts with a Data_ACK　　 value of 2 (Read OnlyNot Writable).　　 Must set the N fuel dispenser b_Products to the value of　　 products that is hard coded in their program.　　 When a master resetcold start occurs on the dispenser　　 device the dispenser should reset this Data_Id to its　　 default value.　　March 2006

around. At the same time, land is moving up and down, because parts of the northern hemisphere are still bouncing back from the weight of the ice sheets they were carrying 20 millennia ago, and the southern parts of those continents are going down as the northern parts go up. So Scandinavia is rising by around a metre a century; Loch Lomond in Scotland is rising by around 1mm a year; and London is sinking by about the same amount. Until 13 years ago, all the available data on sea levels were collected by hand from ancient tide-gauges. But in 1992 satellite data became available that allowed sea levels to be measured in the middle of the oceans as well as at their edges. Those data suggest that sea levels are currently rising by around 3mm a year; land-based data suggest that the rise accelerated from an average of around 2mm a year over the past century to 4mm in the 1990s. Sea levels are rising for two reasons—because water expands as it warms, and because ice is melting. That is where Larsen fuel dispenser B, and some new findings from Greenland, come in. The collapse of Larsen B was not, in itself, all that important. What ma fuel dispenser tters is the relationship of ice shelves to the glacier and the ice sheet behind them. “If ice sheets are cathedrals,�?says Richard Alley, a glaciologist at Penn State University, “ice shelves are the flying buttresses that secure them.�?Ice shelves are especially vulnerable because there is water underneath them; and if the water warms, the ice shelves get thinner. Mr Alley reckons that for every 1°C increase in water temperature, ice shelves shrink by 10 metres. Galloping glaciers Scientists knew that Larsen B was deteriorating, b fuel dispenser ut had not expected what happened after it collapsed. It turned out to have been acting as a brake on the glaciers behind it. When it went, they started moving faster; and the faster they move, the faster they melt. According to data analysed by Dr Scambos, the four glaciers behind Larsen B were moving between two and six times
