cool driver

History start with a joke. This year, April 1, iPad two days before the official sale of market knowledge “iPad ICADE accessories available on the Internet, known with its development of software and hardware can iPad is a little arcade game, NP-FC11 , price only U.S. $ 149.9 and photos and a detailed description so that widely sought Apple fans, also known as “the most cattle iPad accessories.”

Although the publication’s Web site confirmed that this product is a Fool’s Day joke, but today, many national media is often portrayed as IPAD another essential element, causing many users question At the end Where could they afford it? This shows that the hidden power IPAD, iPad incarnation as the IT market quickly on a piece of fat meat, because the letter “Apple” and profit, iPad true identity is yet to come, the accessories have been fire.

Small plants of the LV to the unknown

In fact, Icade “iPad Arcade Cabinet” short, literally means “arcade”, many people mistakenly think that really, because the release of the product site, originally called for “smart geeks” selling their own products on various types of accessories design.

Overview Although just a joke, but something more incredible is true, for example, in May LV (Louis Vuitton) has introduced two awards U.S. $ 320 in the protective cover iPad. In an earlier interview, Brand LV chief CEO Carsley said it cost 1850 U.S. dollars 为 of “style classic crocodile skin” iPad Bao Hu Tao, “I remember when I heard Jobs selling more expensive than the protective cover iPad iPad when the face that look of surprise. ”

“10 years read it slowly and build high-tech products, not as good as sewing a package break,Canon LP-E5 Charger ,  do not know if Steve Jobs can not be calm and collected!” Such a tease LV IT sector point in this concept: “Imagine you have just purchased an iPad, then think, God, iPad only U.S. $ 500, so cheap, how can I highlight the extraordinary state of wealthy and noble? I must immediately find a case to show my identity, then there is this close to asking price U.S. $ 2,000 of coverage iPad protection. ”

However, some analysts argue that all anomalies are a manifestation of the vitality of accessories iPad, in fact, behind that small manufacturers are not known to the sale of accessories, leather, paper aluminum for special clothing variety, especially iPad size fits all, make these products and how hot devices even more than the iPhone.

“Cottage iPad is difficult, give, it is easy to wear

Facts have proved that the use is not as simple as can be dragged into the altars, iPad available for almost half a year, not only the leading manufacturers of products without serious competition, has always been known for speed and low cost house “cottage” to product manufacturers not too satisfying. However, many people beyond the IPAD on the road too dangerous and sigh, another way is wider convert “the education of Apple, design iPad peripheral accessories.

“Many people think the Nuggets iPad is the development of software, by cons in the App Store waiting for users to download to make money, in effect, the peripheral parts of the easiest, most low-tech “. Operates an online store Wang starting from the iPhone, it specializes in providing a foil devices, leather bag, cover, silicone iPad later, he received the volume of order at home and abroad.

According to reports, after the fire early in the iPhone, the peripheral components of the iPhone on the popular network, due to the peculiarity of the iPhone, a number of online store has also introduced a ” brush “service, a price quite normal to ask several hundred dollars. Now iPad another fire, and the possibilities to follow naturally.

“Parts of size larger than the iPhone iPad more devices in the playground.” Establish a number of industry professionals, such as package iPad mobile iPad protective cover to protect the touch screen and back without scratching the sheet, silica gel sets, all kinds of personalized stickers, these companies on the continent has not been much more difficult to attract many small businesses are also involved logic.

Cost more than 1 yuan to 70 yuan sale

In the current price of domestic sales, Apple original parts are particularly expensive, such as protective cover price of U.S. $ 39 asking price of 600-800 yuan are common, it is a great opportunity for small domestic firms.

“A leather protective sleeve called the asking price of 100-200 yuan by selling well.” Wang said that as IPAD not officially on the market, VW-VBG6 , users are mostly parallel to the trustee or buy back from abroad, over bare metal, but many elements IPAD must be used at home to buy expensive, naturally pushed their profit margins.

It is understood that the public offer, the price of paper based application within 30 to 70 yuan, the protective cover, protective cover, in leather bags from 100 to several hundred dollars. One wholesaler said that the cost of such a film is only 1 yuan more than 8 yuan outside the wholesale price, too, while the protective cover silicone, handbags and other costs will not exceed ten dollars, the benefits can be seen.

Compared to those servants ‘cottage’ manufacturers, the U.S. has more legendary stories. As in January after the release of IPAD was ridiculous, people have joked that the name refers to feminine hygiene pad, a named Clark (Kate Clark) of the woman’s family to ridicule again developed a white exterior of the same type as feminine hygiene pads iPad protective cover, called “IMAX”.

Clark does not expect the price to $ 30 for the launch of their designs immediately after being searched, now sold over 100, and because too many orders, it had to find a foundry to help cope with orders.

Foreigners coming to China market

He is understood that many U.S. companies are seriously considering formal iPad design specialized products, including clothing, bags business, but this is nothing new and previously released Nike has already had a special clothing for iPod .

Maybe IPAD Yin Wei had been no official sales, some major brands that the U.S. has launched a new product for the Nuggets iPad boom in sales, only a small domestic manufacturers more private Daoteng, Jimo You Zizhusheji the technical content is also low, Er regular brand and not much movement.

“Many people say that learned the inner house” a form, but peripheral accessories such things as simply a form. “Mr. Wang said, the key components are manufactured in China or abroad, the official price of Apple devices manufacturers are a few people, not only to buy their own country, many foreign buyers have come to China for find products.

In fact, not only shop online, hot consumer electronics stores in major cities, nikon EN-EL4 charger , specializing in components for electronic equipment shops, while the iPhone, iPad peripheral accessories such as almost all households, is also a variety of different species sample, forming a huge industrial chain.

iPad border industrial chain

“Not only leaf as a single product, not just a small cottage manufacturers, I think that even some large brand launch designed specifically for the iPad headphones, speakers or other accessories, we are not surprised, after all, We have listed 80 days was 300 million iPad The IT market has become a piece of fat meat. “Said an analyst.

In fact, sellers are not only accessories, power and even the manufacturers of motherboards to find the point of sale costs IPAD. As the charge current iPad is much higher than the iPhone need, many motherboards USB enough power, users can not use the computer for the cost of iPad this, ASUS, Gigabyte, MSI and card manufacturers Other mothers have free mainstream support “iPad” of the motherboard.

Business Marketing intact by IPAD. Some surveys have reported an online store has launched an iPad buy the object of a certain amount of money earned wireless router offer, causing an explosion in sales of wireless routers. NB-7L , The number of reports by foreign media as out of stock iPad was due the state, many non-Apple stores began taking iPad store selling accessories sales strategy, if the consumer does not buy protective cover, tapes and other products not even think about Buy IPAD.

Google and Apple for a time before that friends become enemies, especially in mobile devices unit 2 is fiercely competitive, but he can not keep Google as Apple Senior Product Manager,VGP-BPS15 ,  Google Enterprise Dave Girouard, the president recently made public Apple flat-screen machine iPad popular, admitted rushed to the good graces IPAD iPad and he thought Google’s success is also a good thing.

To some extent, Google iPad is not considered a good gift, because the device is running a local application, and Google tools and services are web based. However, Girouard said, IPAD is “to promote global access to cloud computing, one of the various types of equipment, including the use of Google Chrome OS products.

These devices over the traditional Windows PCs and Macs cheaper, so it is easy to replace conventional equipment,dell Vostro 1220 battery ,  and most of these devices online store or convey information and applications, that Google will benefit of the future, the online tool of the device to his muscles.

Note purchase of electric vehicles and maintenance tips

    Currently, the batteries in electric bicycles a lot of variety. In addition to using the largest valve regulated lead-acid batteries, there are batteries in nickel metal hydride batteries, nickel-cadmium batteries, lithium-ion batteries, lithium polymer, zinc air batteries fuel cells and so on. Among them, the greatest number of lead-acid batteries is. The price of lead acid batteries lowest, so the batteries most commonly used lead in China is the largest producer in the world. Components it contains less pollution, recycling is good. Disadvantage is the specific volume of small size. In other words, the same capacity, the battery weight and size are great. The current lead-acid battery is essentially a type of floating battery changed. Not suitable for rapid charge and float charge the battery current discharge, although the technical staff devoted considerable efforts have been effective improvements can access the utility but his life is still very unsatisfactory.

    Specific volume of the Ni-MH much better than lead acid batteries, the battery life alone is relatively good, high current charging and discharging characteristics better than the lead-acid batteries. The problem is the connection of the battery Ni-MH battery management are more problems after the overload, they form a single battery problem of separation of fusion, which leads the group of batteries with failure. Therefore, China-made nickel-hydrogen battery charger or key technology and the problems of battery management systems, and this problem did not cause any attention from the battery manufacturer and deposit sufficient.

    Therefore, the development of nickel-hydrogen battery has been under considerable stress. Ni-Cd large current characteristics of the Ni-MH is right, its characteristic resistance to overload NiMH batteries than good, China is the leading producer of nickel cadmium battery. Some people have raised the issue of cadmium pollution in China is still significant exports to Europe and applications of nickel-cadmium limit until 2006.

Buy battery electric bike, a product logo to see if complete including the manufacturer name, product specifications, date of manufacture, mark, see the consistency of internal and external signs, in particular, to verify whether products are eye-catching signs, production date should pay attention to whether the recent. Second, we must pay attention to the emergence of the battery. View products with deformations, cracks, scratches and signs of leakage. The battery terminals should be clean, no rust, signs should be clear. The third is concerned about the batteries of electric cars at the rated capacity. Battery rated capacity marked on the larger, the discharge of the battery, it is better not to buy non-rated labeled cells, but attention to whether the particular electric car, if the mark greater capacity, are subject rated capacity. The fourth is to buy reputable companies, large companies brand batteries. Battery usually provided by a professional battery manufacturer, different brands of batteries of different manufacturers vary in quality, price is also a hierarchy. Known, technology companies large and powerful and good after-sales service, the quality of the battery provided.

    Extending the life of the approaching vehicle’s battery power: First, the vehicles use lead-acid battery supply are most afraid of losing power, to be suspended, the best is stop immediately after dell latitude d820 battery ， the power to add to a lot of time not all 20-30 days to recharge a battery compartment and two to ride on the line if you feel the electricity was used, no to wait a while then connect to the use of micro-cell within this, there is the battery power saving lives, if it continues to close I use the power of saving lives, a large impact on battery life, third, that accompany the magazine, generally a function of float, as long as the time for each count within 12 hours of the basic drum is more good than harm. Just note that the three points above, make sure your battery life in good condition.

1, how to charge the battery to the new

The use of lithium batteries should be noted that after a while the battery is placed into hibernation, lower than normal capacity at this time, the use of time has also come to shorten. However, lithium batteries can easily activated, as after 3-5 times the normal battery charge and discharge cycle can be activated to restore normal capacity. As the battery lithium own characteristics, its decision is almost no memory effect. Therefore, the new lithium battery phone users in the activation process does not require special equipment and methods. Not just in theory and practice of mine, from the beginning, the standard method of charging that “activation” is the best approach.

For lithium batteries, “activate” problem, many say, is: charging time must be over 12 hours, three times to activate the battery. This “three times before charging to collect more than 12 hours,” saying, obviously the battery of nickel (nickel-cadmium and nickel metal hydride) inherited from the statement. So, this argument can be said denature the beginning. Lithium and nickel battery charge and discharge characteristics of a very big difference, and can very well tell you, I had access to all data is highlighted serious technical and formal discharge-charge for lithium batteries, especially lithium liquid Ion battery causing great harm. Mini 730 ， Accordingly, the best method of charging by time and normal load standard in particular for not more than 12 hours of super-long charge. Generally, the declaration submitted mobile phone charging method is suitable for charging the mobile phone standard method.

In addition, the cell phone charger or a lithium battery automatically shut off after a full load and no charger nickel diet for 10 hours is called the net “care. In other words, if lithium batteries in full, on the white horse is also sufficient. We can not guarantee anyone the battery charge and discharge characteristics of circuit protection and never change the quality of security so that your battery will be at risk of long-term edge. There is also another charge against the main reason.

In addition, on some phones, the load over a certain time, if not remove the magazine, this time not only to stop charging system, will start to discharge - charge cycle. Perhaps the makers of this approach has its own purposes, but apparently the battery and cell phone / charger is detrimental to living conditions. At the same time, long charging would take some time, frequently requires night and our power grid situation, at night in many parts of the tension is high and volatile. As already said, lithium is delicate, and its power as nickel resistance in the charge and discharge aspects of fluctuations in capacity much less, if this brings additional risk.

In addition, another aspect can not be ignored nor is it suitable for Li-ion battery on discharge, over-discharge of lithium batteries also very unfavorable. This led to the following questions.

2, normal use should be time to start charging

Often see this argument, because the number of charging and discharging is limited, so it should be possible to run out of phone battery charging. But I found one in charge of the lithium-ion and Table discharge test cycle, the data life cycle is as follows:

Stages (10% DOD):> 1000 times

Stages (100% DOD):> 200 times

What is the depth of discharge DOD abbreviation. Maybe the table shows, the number of charge cycles and the depth of discharge, 10% DOD cycle life when the Department of Defense 100% for much longer. Of course, if the effective charge equal to the total capacity on 10% * 1000% * 100,100 = 200 = 200 full charge and discharge of the latter is still better than some, but previous users of this claim to some amendments: Under normal conditions, 537627-001 ， you should have reservation in accordance with the remaining battery power is exhausted and the principle of full load, but if your battery is expected in the first two days you can not respect the day they should have started charging time, of course, if you’re ready to return the charger to the office is another question.

And you need to charge to meet the expected future busy session communications led to important events of the day, although there are a lot of battery power when I, then you are simply charged ahead,因为 you’re not really lost, “life cycle” under load, that is, “0.x” times only, and often it will be very low x.

Remaining battery runs out and the principle of perception is not that you go to the extreme. And long widespread distribution charge, saying that “as far as possible the cell phone battery is exhausted, it is best to use automatic shutdown.” This is really just practice on nickel batteries to avoid occurrence of memory effect, unfortunately, NP-BK1 ，it is also spread of lithium in this regard. It was because the cell phone battery low warning is still no charge to use the sample was used in automatic shutdown. The results of this case, mobile phone charging and later in the boot there is no response, had to give customer service overhaul. In fact, the result excess discharge due to the battery voltage is too low, do not have a normal result of the charge and the starting conditions.

Researchers at the University of Illinois is a silicon wafer by “culture” of layers of materials, developing low-cost GaAs thin film solar cells.

GaAs is a compound semiconductor, HSTNN-CB0C can be used to produce solar cell conversion efficiency and energy than traditional silicon-based solar cells more potential.

Currently, researchers have made the conversion efficiency of 25% to 30%. However, high manufacturing costs of the technology is still a major obstacle to commercialization.

The School of Materials Science and Engineering Department of Chemistry, Professor JohnRogers and another XiulingLi teacher are looking for low cost technology to produce gallium arsenide thin film. At the same time, they also hope to find a common way to make the production of a film for a variety of devices.

production of GaAs solar cells is usually a small piece of silicon on the deposition of the compound until the surface of a thin layer. Researchers at the school changing the way the surface of silicon layers deposited on GaAs. This structure, the GaAs and AlGaAs thin layer arranged alternately, like Americans eat the same school.

‘Using this method, we can use a faster and cheaper, to get more products. ” Professor Rogers said: “Although we produce only thin, but overall speaking, we produce much more important. ”

“If a 10-layer growth can be fine, this means that 10 layers are only a thin slice,” Electrical and Computer Engineering,  nikon charger , Professor Li said. “If you take 10 times the growth response, the process Reaction of the installation and removal of silicon, and after heating and cooling, need much time. If the machinery, preparation of materials, time and personal factors taken into account, our method can significantly reduce production costs. ”

The study group in the journal Nature published a paper to clarify the process can be used for three types of devices - light sensors, high speed transistors and solar cells. They will also make this material compared to other materials.

The authors, two were scientists of the company are Semprius. The company is located in North Carolina, 537626-001 ,  is a business objective is to use emerging technology in the study group to produce solar cells.

 Theme of the study group funded by the U.S. Department of Energy and National Science Foundation.

Energy saving and new energy planning for the automobile industry development policy and, once implemented a package of support, will trigger a new wave in the wave of the market for new energy vehicles. But a closer examination of all related sectors of industry, because of differences in the localization of the major industries in which different degrees of difference between the industry chain for the benefit of a lot. Most experts interviewed believe that the basic order for the benefit of the industry is the battery, motor, power plants and other parts and accessories for the best service, followed by vehicle manufacturers, the area upstream of materials again.

Battery, Power Plant

The value of most investments link

In the new energy automotive industry, which in the field of “cake” Max? With the emergence of new energy technologies, companies in time of the internal combustion engine vehicle to shine for the other case is replaced by a number of parts from the industry across the threshold of hope, become Member car manufacturers. Analysts said the market increases, the battery, motor and other component manufacturers the most benefit, most importantly, the manufacturer of these parts or modify the current structure of the automotive industry.

Industry experts said that in internal combustion engines of the time, the value of complete vehicle business, which represents 25% of a car, 75% of the cost of parts and components supplier in. At the era of electric vehicles, a car almost 90% of the manufacturing cost will be spent on parts and components sectors, much is the car battery.

“The battery is the string of new energy automotive industry is the most important part of the value of the investment. Compared with conventional cars, vehicles with new energy essentially determines the performance of the battery of the vehicle driving performance “. Analyst Wang Jing said.

new energy battery is the most automobile key basis, as provided lithium-ion batteries will soon become an alternative public to the Ni-MH battery, lithium battery powered vehicles on the new power demand-pull as a means separate institutions for discussion. Clearly, dell gd761 , the lithium-ion batteries, electric motors electric control companies in the automotive industry related to the chain will face greater opportunities for development.

“Europe, the United States, Japan, the traditional engine cars have a greater advantage of the hybrid H EV in Japan have a greater advantage, and a large number of patent applications. China within two tracks are little more than foreign industry. China selected plug-in hybrid EV PH, EV electric line, a goal of long-term development consistent with the automotive industry, while China in the battery, engine the resources of lithium, the Earth’s resources have a comparative advantage (310,368, fund it), there are long-term benefits of new energy vehicles in development. “CRE securities analyst Gregory believes that online base of the lithium battery positive determination.

“Automatic support new policy and greater energy, has made clear its path of long-term development, gradually feed the needs of the market, but can grow to be as expected. In the development of electric vehicles, batteries benefit from a greater variety of China has been more negative and the electrolyte mature, sony vgp-bps8 , positive gradually mature, mass production is now mainly to solve the stability problem. Lithium is the general trend of development in the long term. “CRE Securities expects the new energy vehicles in 2012 will exceed 100,000, 6 billion battery industry can lead the market in the next three annual growth of over 50%.

Among the summer, the air conditioning has become essential equipment, but the higher electricity bills and the resulting environmental impact on the Earth is the first major. Recently,laptop battery   the National Renewable Energy Laboratory (NREL) scientists have developed a new type of air conditioning, compared to products currently on the market can save up to 90% of energy.

We learn that scientists use fracture, evaporative cooling, liquid desiccant and so on until energy efficient. Air conditioning cooling output of air conditioners increases humidity, which means they can only work in dry air very well, and the development of new so-called “enhanced conditioning evaporative air desiccant (DEVap) In addition to using liquid desiccant air cold and humidity.

In fact, technology is not the first principle, but NREL scientists to join existing research on the basis of its original technology, particularly the use of refrigerants salt alternative will not be harmful CFCs (CFC ) and with hydrogen chlorofluorocarbons (HCFCs) - know these substances contribute to global warming is carbon dioxide about 2,000 times.

Simulation tests show that the city of Phoenix and other hot and dry environment, if you use natural gas for heat,Dell Studio 1535 battery ,  then air conditioning DEVap can save electricity by 85% and 80 % of energy.

If the air DEVap can successfully market, whether for electricity or energy saving benefits are great, but it is clear that this was impossible. NREL continues to improve technology, trade hopes this year.

Recently, some users have complained, there is the power of digital cameras, Canon PowerShotA570IS problem of false positives, even if the battery is fully charged in the camera, still camera low battery warning. laptop battery  We found 07 products for this digital camera has been a complaint online.

In the complaint, the number of consumers than the “full load, it was not long, the device of sufficient power to suggest”, “high quality battery installed, the camera continues to indicate low battery and extinction Automatic soon, “and so on. 315 complaints from consumers online, Canon in the face of such complaints, the answer almost always advised consumers to local maintenance point for detection, there is no concrete answer to the question.

315 complaints from consumers in the Internet have also seen the problem of complaints Canon battery device of false positives are not limited to PowerShotA570IS this paragraph, there are many types of products also appeared the same problem.

Internet search found a number of vertical sites in the community, many consumers complain about this problem, there are consumers willing to disassemble the camera yourself, that by modifying the circuit to solve the problem. Dell Latitude E6400 battery ,  In the Chinese Canon site, the journalists could not find the Canon to explain the relevant issues, has not found a solution to these problems.

This year, March 24 People made allegations of Chinese report digital camera market situation shows that in 1000 consumers were interviewed 3, Canon, Sony, Nikon has a volume of three marks the first three, respectively, 30 %, 23%, 17%. The Canon was the largest number of complaints, which represents 57% of the total complaints. For Canon digital cameras, consumers are more questions to reflect as: business shirk his responsibilities, arbitrary charges, the maintenance level is not high; attitudes of poor maintenance, the cost of maintenance is too high.

High-low-cost return, makes the recycling of waste batteries as chicken ribs.

Although China has made mercury-free batteries do not need to focus on recovery, laptop battery but environmentalists are still voluntary collection of used batteries. However, the recovery has become a disposal problem. Currently used methods is to focus on the landfill, handling charges 1,000 yuan per tonne, which is a lot of recycling old batteries, after being shelved.

Bank of Ningbo Battery Co., a soldier of the High Chief Engineer, said that instead of causing pollution:

You hear a lot of thrown into the yard, the sun and rain, the race positive and negative short of a short-circuit leakage has increased, it was polluting the streams, more than being serious.

Ningbo Environmental Protection Bureau, said director Xie emphasis Xiaocheng new landfills is also a disadvantage:

After buried in what is troublesome, a place not a re-planted on the way to the high cost of battery recycling, refining, and then pays off.

annual consumption of China at least 5 billion batteries, while other metal waste battery recycling site has value, sony vgp-bps8 , but the technology is limited, because low rates of return of waste batteries as chicken ribs , eat a symbolic gesture.

EPA Solid Waste Management Center, Ningbo City, director of Tang Wenbiao: Did you remove and separate, it may consume more resources. You need human resources and material, you must use electricity.

Core Tip: Staff explained that the film contains the top panels of the installation of an amorphous silicon thin flexible solar. During the day solar panels solar power stacks up the lighting in night shelters for the battery again.

Heating drinking fountains and shelters solar solar …laptop battery  … Recently, a variety of energy saving technologies in the Fengtai district in Beijing, unveiled energy saving publicity week, which attracted many new eyes.

Open space outside the room, there is a 2.5 meter solar shelters. Although shelters do not seem different from normal, he is able to self-sufficiency in electricity for lighting.

“The secret to the summit.” Staff explained that the film contains the top panels of the installation of an amorphous silicon thin flexible solar. During the day solar panels solar energy into electrical energy accumulates, the source of light at night to power battery backup in shelters.

It is understood that sun shelters for five hours of sunlight per day, sony vgp-bps8 , the lights of 100 watts for about 10 hours of continuous use. “The light box can be used for food for three days, the equivalent of saving 1.3 kWh per day, and we plan to promote the city.” Plant personnel said.
