ariable DC voltage. Diagram 3-9 is a drive circuit. The display mo fuel dispenser de of volume and sales on main display board adopt 6 digits liquid crystal display (Model ED-139, see Diagram 3-11), PPU or unit price r digits LCD (Model ED-830, see Diagram 3-12). Diagram 3-9: Static circuit and wave of LCD tube Diagram 3-10: Drive circuit of one-digit tube Diagram 3-11: ED-139 6-digit LCD Diagram 3-12: ED-830 4-digit LCD Display drive chip often adopts 8-digit memory/flip-latch: 74HC95. The drive circuit of liquid crystal display is composed of double D trigger 74HC74 and double input exclusive-OR gate 74HC86. Some fuel dispensers adopt special crystal drive circuit in liquid crystal display, its principle basically similar to 74 series LCD drive circuit. A few fuel dispenser manufacturers adopt light-emitting diode (LED) as display components of display board because its cost is low and need not backlight in evening. The defect of this display component is bad display effect, especially under extensive sunlight, and much electricity consumption. LED display drive circuit also has parallel and serial drive, similar to LCD display drive circuit in terms of structure. Very few fuel dispensers adopt matrix or color liquid crystal display, showing much information. However, it largely increases cost. 2.4 Power supply Stable voltage power supply used in explosion-proof fuel dispenser Most of fuel dispensers adopt explosion-proof type, installing liner stable voltage power supply or switch voltage power supply. Switch voltage stabilizing power supply includes power transformer, DC/DC converter, 220V direct commute and pulse transformer, illustrated in Diagram 3-14 and 3-15. Due to cost-efficient and simple design, liner stable voltage power is widely adopted. However, it is affected by exterior network voltage. Although pulse transformer is fuel dispenser able to tackle with network voltage fluctuation, it is can’t afford because of complicated technology, expensive cost and difficult to maintenance.

ve. Fortunately, Microsoft already has within the firm units that fuel dispenser have demonstrated the agility and online awareness that the whole company now needs. The Xbox gaming unit boasts more than 2m paying subscribers for its Xbox Live service—which allows users to download games and entertainment and chat—and is the model for Windows Live and Office Live. Meanwhile MSN has captured a small share of the roughly $10 billion online advertising market. But the anchor products of Windows and Office, which in effect subsidise these ventures, have not evolved to reflect the new online era. So Microsoft now plans to graft subscriptions, downloadable add-ons and advertisements on to its core products. Again, it portrays this as an opportunity to open up new revenue streams, rather than a defensive tactic. “There are three ways to pay for anything in this business ads, transactions and subscriptions,�says Craig Mundie, one of Microsoft s chief technology officers. “You ll see the company offer a full range of different ways to buy our product.�The difficulty will be getting the timing right, so that new products do not undermine existing cash cows. For now, however, too many Microsoft managers are still measured by their success with yesterday s business model—selling boxes of software. Microsoft is still formulating its response to the rise of online software. As one former Microsoft executive explains the company s problems are not just technical but organisational. “It has a vision but not a roadmap; it can see the peaks but doesn t know how to cross the foothills to get there.� © 2006 .  About sponsorship Telecoms and TV The future is Now Mar 30th 2006 | HONG KONG From The Economist print edition Hong Kong s incumbent telecoms firm has blazed a trail in televi fuel dispenser sion services “JUST about every phone company in the world has come through here,�says Alexander Arena, the finance chief of PCCW, Hong Kong fuel dispenser
