re approval working successfully being conducted. Environmental temperature as approval should keep in the range of �0�to �0� in approval process temperature not exceed 3� relative temperature between 30�and 90� power supply within �0% to �5%; and frequency ±1Hz. The mediums used in approval should adapt real media excepting in factory approval. As different medium would be adaptable to fuel dispenser, every medium should be appraised. Some of them are prohibited, especially water. The highest temperature of medium in approval should not exceed 30� the lowest temperature without coagulation. The temperature difference between the one at the outlet of fuel dispenser and t fuel dispenser he temperature measured in standard instrument should not exceed 4� Otherwise, the approval is invalid. Standard instrument used in approval whose measuring accuracy no lower than one fifth of the allowed tolerance of fuel dispenser, should pass over appraisal of the Measurement Department and be valid within period. There are many standard instruments being adaptable to fuel dispenser’s approval, however, the most popular one is standard metal instrument of measurement. Standard metal instrument of measurement adapted in approval should, in accordance with the requirement of fuel dispenser’s regulations and procedure, be Class II standard metal instrument of measurement with cubage no less than one minute’s discharge volume of fuel dispenser, approval period being 3 years. Standard metal instrument of measurement often is made of stainless steel or carbonized steel with protecting painting, no air vent, erosion-resistant and smooth surface. Its structure is shown in Diagram 8-1. 1: Overflow cover 2: Metering neck 3: Body 4: Bracket 5: Adjusting bolt 6: Drain valve 7: Leveling instrument 8: Scale Diagram 6-1: Sketch map of metal standard instrument of measurement Standard instrument of measurement is composed of overflow cover, body, measuring neck, scale, valve, which should meet the follo fuel dispenser fuel dispenser

ommunication (layer 6).　　4.1 Addressing　　Each device will be locally able to define its own node address that means: Subnet and Node　　numbers (S N). Different solutions are possible:　　 - dip switches or similar mechanical solution　　 - address provided by the application running in the host processor.　　- Subnet (S) Node address (N): 2 bytes　　 The choice is to use the Subnet address (S) to indicate the device type.　　 A list of all valid Subnet addresses is given in Engineering Bulletin Number 8.　　 N: All devices belonging to the same Subnet (so having the same type) are　　 identified by a unique Node address (N). T fuel dispenser he values are 1 to 127.　　Please note that the SubnetNode assignments must be implemented at the Application level.　　However to allow multiple devices to be interfaced via a single Echelon Neuron chip (i.e. An　　OPT that consists of a PIN Pad Card Reader Receipt Printer Journal Printer) it is　　permitted to use a different SubnetNode address in the application message than the actual　　network Neuron chip SubnetNode address.　　Example:　　When addressing a PIN Pad (S4:N1) that is connected to an OPT device with its Neuron chip　　configured as (S6:N1) the Transmitting Neuron chip will transmit at network level to the　　OPT device (S6:N1) but in the application message will use a Recipient Subnet address of 4　　and a Recipient Node address of 1.　　Where: S4:N4 = S4 is Subnet 4　　 N1 is Node 4.　　It is therefore up to the application layer to decipher the incoming message and then route the　　data to its respective device.　　4.2 Application Protocol Parameters　　- Block Length:　　 The Block Length is set by the Max_Block_Length communication data element. The　　 range for the block length is 32 to 228. To allow messages longer than this value a　　 Block Number BL is included in the message.　　- C fuel dispenser fuel dispenser

wspaper man, would choose a racy, left-leaning social network at the forefront of the trendy “Web 2.0�movement. The firm is now working hard to prove that it can make plenty of money from MySpace s traffic. To a large extent, Mr Murdoch s new internet strategy hangs on the site s success. News Corporation has responded quickly to try and protect MySpace s youngest users. It will appoint a safety “tsar�to oversee the site. As for advertisers, Ross Levinsohn, News Corporation s head of new media, says that some have expressed concerns. But he points out that advertising revenues are doubling every half year. Plenty of prominent advertisers, such as Toyota and Wendy s are usi fuel dispenser ng the site, and Hollywood is using it to create buzz about films. Richard Greenfield, an analyst at Pali Research, agrees MySpace is now earning advertising revenues of about $13m a month, he points out. Provided that the company takes propriety seriously, says Mr Greenfield, MySpace will continue making money. Although some admen are warning against the site in public, many of their clients are in fact staying on it. MySpace, after all, captures the attention of young people, whom advertisers are struggling to reach through television and other traditional media.MediaPost recently quoted David Cohen, executive vice-president at Universal McCann, an ad agency, saying that he “wouldn t be caught dead in that kind of environment� Nevertheless, several of his firm s clients advertise on MySpace. The key to using it safely, says Mr Cohen, is to stick as much as possible to the bits of the site that News Corporation builds, and to tread carefully when placing brands near unpredictable “user-generated�content. Universal McCann has also negotiated the ability to pull down ads in one to two days, more quickly than the usual two weeks notice. “We can be out of there in a heartbeat if need be,�he says. Another attack on MySpace has come from Jupiter Research. One of its analysts, Nate Elliott, has sai fuel dispenser fuel dispenser
