Apple CEO Steve Jobs (Steve Jobs) at Thursday’s annual shareholder meeting held, said he thinks Apple’s best not to spend 25 billion U.S. dollars in cash balance.

Asked whether Apple will use the cash balances held to cover the dividend issue, Apple CEO Steve Jobs (Steve Jobs) said the company’s cash holdings of the way through to keep the “great security and flexibility “, implying that its not support this idea. He said that if Apple A1008，A1012 decided to conduct M & A transactions, then a way can be used in cash rather than debt financing.

Other Apple executives also said that the company intends to in the Chinese market on an ambitious development plan, is expected to be in the next two years in China to open up 25 new retail stores. Apple’s first retail store in China in 2008 opened in Beijing.

At this meeting, Apple shareholders rejected two proposals, its content is to require Apple to take additional measures to the company to the environmental impact analysis. Apple has always opposed both proposals, and said investors have rejected these proposals, but did not disclose the vote. Jobs noted that Apple is taking a number of environment-related measures, such as the supply of commercially available non-toxic materials required to manufacture products, and reducing packaging to reduce waste and so on.

The past ten years, as people get new fuel technology to grow by leaps and bounds, lithium battery industry has shown more and more obvious to assume the new energy revolution, an important feature of mankind.

South China’s lithium by listening to the fourth high-level forum on Chinese and foreign experts to give lectures on the above had a profound understanding of the impression.

The U.S. government shot to support the development of Inspiron 8500 battery,Inspiron 8600 battery Industry

U.S. Lithium acting chairman, the U.S. chairman of Sharif Broad Buluodepu Dr. speech at the forum referred to the recent U.S. Government’s new economic stimulus program. According to his own observations, felt he came to the United States since 1981, after 20 years, the U.S. government is an unprecedented effort to increase financial support for the industrial sector. In the United States and the Government’s financial assistance program, there are two billion U.S. dollars for the battery industry; of which about 1.2 billion U.S. dollars, mainly used in batteries and battery to do the development.

Dr. Sharif Broad said that in this whole industry unique among the funding operations, the battery industry, the focus has been placed among the “top priority.”

Lithium-ion batteries have obvious advantages

Lithium-ion battery as a lithium metal battery upgraded version, with very clear advantages. It has a high working voltage, small size, light weight, high energy, no memory effect, no pollution, little self-discharge, long cycle life characteristics are optimized for battery electric vehicles as one. Present in this area’s top technology “stack Inspiron 9200 battery,Inspiron 9300 battery structure” will soon be made of several thin layers of cells, and then overlapping, so that access can be achieved in very small volume of high efficiency. At present in this area in order to Nissan Motor Co. to go the forefront in the application.

In order to improve ease of use degree, the current number of electric cars, lithium can be charged using ordinary household voltage, but the downside is that it takes to charge up to several hours. For large-scale promotion of Li-ion battery car, you need to establish a corresponding rapid charging stations. In March of this year, Japanese researchers have developed a new type of “Lithium - air” battery, this battery without charge, simply replace the cathode water-based electrolyte, through the card box, etc. to replace the lithium metal anode can be used continuously. In other words, charging facilities to add an object like a “filling station” rather than a large bolt with a “battery charging station.”

Development of renewable energy sources Lithium-Ion battery is shouldering heavy tasks

“Fourth High-Level Forum held in South China Lithium-Ion battery suitable for the time!” This is the forum was attended by CAS academician YANG Yu-sheng told reporters sent from the past. Academician Yang considered the appropriateness of the time not only because of our electricity production of lithium in the world, second only to Japan, China is already the production of lithium battery power, but also coincides with our national attention to the development of renewable energy, the lithium battery which can play in this great role.

Academician Yang told reporters said that lithium can save a lot of petrol used in cars. It can be wind, solar and other clean energy stored up, and when needed to use them.

He said that over the past 15 years, lithium-ion battery batteries in promoting technology industry throughout the world have made great contributions. In the hybrid vehicle, external plug-in hybrid electric vehicles, fuel cell electric vehicles and pure electric vehicles electric cars four different principles which, he praised a pure electric car, “I think we should give priority to development, and he does not have oil, suited to China’s short of oil state of the nation “, in addition, its structure is relatively simple, non-asphalt, land and water use and maintenance, are very convenient, while saving material and energy.

According to Academician Yang introduction, the current lithium are from small to large, from a unipolar to the series and parallel, from the low-power to high power directional change, while the forum on the lithium Inspiron 9400 battery,Inspiron B120 battery, new materials, new technologies, new applications for the many discussions, Obviously it is very timely.

Buy Pocket PC PDA batteries, but also will pay attention to conditioning your batteries. PDA Pocket PC now tell us about the proper use of batteries for your reference:

1, the former 3-5 second charge commonly referred to as an adjustment period, more than 14 hours should be sufficient to ensure the full activation of the lithium-ion activity. Lithium-ion Inspiron 1720 battery,Inspiron 1721 battery without memory effect, but a strong inert, should be given adequate activated in order to guarantee that used to achieve the best performance.

2, the battery factory, manufacturers have carried out active treatment, and conduct a pre-charging, the batteries have more than electricity, a friend of mine said that the battery charge in accordance with the time period of adjustment, standby is still a serious shortage, if the battery is indeed the genuine battery, then this kind cases, an adjustment period should be extended to 3-5 times and then fully charge and discharge (Li-ion batteries have an adjustment period the proposed discharge is placed on PDA Pocket PC does not work until it automatically shut down, if the local network or the location is very power , then remove the SIM card, bare metal boot until shutdown).

3, if you use not compliance, it may be insufficient to fully activate the battery charge current (commonly known as electricity or charge can not be recharged into unsaturated), resulting in such a situation may be placed on unused for too long, or because the factory could not be full activation (activation) process because at this time is the best for all our friends to a PDA Pocket PC maintenance department to apply for the battery to make an activation treatment (or called by adding “counter current” for activation); understand the power of the friends yourself with a constant voltage DC device, adjusting the voltage 5-6V, current 500-600mA reverse battery connector. Note that the liberalization of touch, up to repeat three times, you can, and after such treatment, use the “original travel charger” to “adjustment” charge. In general, after such treatment, PDA Pocket PC batteries should not be any problem.

4, according to the type and capacity of different batteries, battery charging time is about 1.5-6 hours, not more than 24 hours.

5, battery life determined by the number of repeated charge and discharge, it should try to avoid battery power than when charging, it will shorten the battery life. PDA Pocket PC shut down more than 7 days, should be first PDA Pocket PC battery fully discharged, adequate electricity and then use.

6, nickel-cadmium (NiCd) batteries must be guaranteed before the battery completely dead, then charge must ensure that the battery fully charged.

In addition, from the environmental point of view, scrapped PDA Pocket PC batteries Inspiron 2600 battery,Inspiron 2650 battery should be recycled, are not free to litter. Abroad, PDA Pocket PC battery recycling must comply with the Government and the battery manufacturers to develop inter-recycling program. In China, PDA Pocket PC Battery lack of recovery system. 1 million each year from several PDA Pocket PC battery scrap, if not recovered in time, it will cause long-term harm the environment.

(4) The charging voltage

Charging voltage is the secondary battery charging, the external power added to the battery voltage at both Inspiron 1300 battery,Inspiron 1420 battery ends.
The basic method of charging Youheng current charging and constant voltage charging. Generally use the constant current charging, the characteristics of the process of charging the charge current constant. As the charging progresses, the active substance was restored, the electrode reaction area is shrinking, the electrical polarization gradually increased.

(5) Battery Capacity
Battery capacity refers to the amount of electricity from the battery to obtain, often C, said the unit, said common Ah or mAh. The electrical properties of the battery capacity is an important indicator. The battery capacity is usually divided into theoretical capacity, practical capacity and rated capacity.

The capacity of the battery capacity of the decision by the electrodes, if the electrode capacity varies depending on the capacity of the battery capacity that smaller electrodes, but by no means the sum of positive and negative capacities.

(6), the storage battery performance and life 
One of the main characteristics of chemical power sources is used to release electrical energy can be stored when not in power. The so-called secondary battery for storage performance is to maintain the ability to recharge your batteries.

For the secondary battery, battery performance measure of good or bad, when life is an important parameter. Following a secondary battery charge and discharge, is called a cycle (or have been in this cycle). At a certain charge and discharge system, the battery capacity reaches a certain specified value before the Inspiron 1501 battery,Inspiron 1520 battery can withstand the charge and discharge times known as the secondary battery life cycle. Lithium-ion batteries have excellent storage performance and long cycle life.

Apple announced that it would from May 2006 to December 2007 a very small part of the sale of MacBook notebook computers free of charge to replace the hard disk, but the company has not formally announced a product recall.

Apple said that if the MacBook notebook computer’s hard drive problems, and repairs have been carried out, Apple will compensate for maintenance costs.

The company also announced the launch of “extended maintenance plan,” part of the problem to extend the warranty period of MacBook notebook computers.

The notebook computer’s hard drive problem is very easy to find: computer can not run, if the user attempts to restart, the screen will appear with a blinking question mark folder icon.

Apple’s Web site said: “This plan will involve MacBook models available from three years from the date of purchase maintenance services. Apple will continue to assess the maintenance of data, and further extended to provide the necessary service.”

However, Apple made no mention of a user due to a computer hard drive failure resulting in data loss compensation.

Global product safety testing and certification leader UnderwritersLaboratoriesInc. (UL) 12 Yue 26 announced it will release its large-scale batteries for electric vehicles in a study of the latest Platform - ULSubject2580.

As people of the growing interest in electric cars, UL Outline of the introduction of this latest research will help to reduce the use of electric car people in the potential risk of fire and electricity, and to strengthen the overall security of electric vehicle batteries. Prior to the official as a standard, this outline will accept a global standard technical committee (STP) for a comprehensive review. STP by consumer representatives, government agencies, regulators, manufacturers and other relevant bodies with expertise, whose aim is to formulate and update the effective product safety standards.

As traditional energy prices and concerns on environmental issues, can be predicted that the use of electric vehicles in the coming years there will be a substantial increase. Worldwide there are several billions of dollars have been invested to manufacture and promotion of this technology, including the 2009 U.S. recovery and Reinvestment Act expressly nearly three billion U.S. dollars, but as a key component of a large-scale electric vehicle batteries in the U.S. market will be much to offer. Orville Consulting international consulting firm in the next decade, the annual Sheung hybrid electric vehicles and battery-powered electric vehicles will reach 1000000-5000000, but at the same time, accompanied by high growth rate from the a potential fire, electric shock and other safety issues.

“Many factors will determine the market, the use of electric vehicles, such as a large batteries cost, performance, sustainability and safety requirements.” UL, general manager of the Global Energy Business Unit, Mr. JeffSmidt said, “UL, we always put safety the first place. through a series of safety standards have been developed requirements and the latest release of the battery safety standard requirements, we can help manufacturers to provide the market with more secure electric car. ”

ULSubject2580 is not mandatory, manufacturers are free to choose whether or not to meet all the requirements of this framework in order to reduce security risks. At present, no such large-scale test vehicle battery battery UL standards.

Microsoft said in a statement, denying its latest operating system, Windows 7 in the Laptop battery management there any problems. Prior to Windows 7 was traced to problems with power management, a number of Windows 7 users battery life under normal conditions, but problems with the system before the battery warning. Since then, Microsoft began to investigate the matter and conducted a series of tests.

Initially, Microsoft Windows7 cells that may be due to some computer false positive problems caused by the firmware. Still, Microsoft’s own operating system has always been convinced that operating normally.

Microsoft, Windows and Windows Live Engineering Steven Sinofsky, senior vice president (Steven Sinofsky) said that according to experimental results show that Microsoft, Windows 7 to determine the accuracy of battery consumption, in any case had almost no false positives . Microsoft has received and all the false failures were identified in the battery, the result is that laptop battery is already close to their useful life.

In addition, he also mentioned this problem only recently emerged, and users upgrade to the latest version of Windows 7 may also lead to the problem, saying, “appears to be a Windows 7 ’cause’ of the decline in battery life, but the actual situation is all about Windows7 previous relevant reports are all the new operating system’s performance affirmed. ”

Microsoft and other computer makers has so far received 20 complaints related to failure, survey shows effect of these problems has been aging laptop batteries, battery endurance decline is a normal phenomenon. Although some users of Microsoft’s TechNet and other forums are still rankled, but shorter lead time for notebook use is indeed the reason is due to the aging of the battery itself, rather than other factors.

Sinofsky said that in the Windows7 test period compared to the current issue of the proportion of false positives occur Windows7 has dropped a lot. Although problems remain, but some may be due to an increasing number of new software (as well as new batteries) and compatibility issues Windows7. At present only a small part of the user receives a “proposal to replace the battery” prompt, Microsoft Windows has been going on for more than 18 months of testing.

“BYD-iron battery project settled Baolong Industrial Zone, Shenzhen, that in the future layout of the new energy automotive industry has been to seize the opportunities. BYD to build the headquarters of the economic building, I accompany you in Longgang site!” February 5 , Longgang District secretary of the Chiang Kai-shek led his unit to the BYD jade statue door service, the company’s chairman, said Wang Chuanfu. It is reported that Longgang District Longgang the full support of BYD in the construction of a high standard area of 50 million square meters, annual production value of nearly 100 billion-iron battery project base and help the economy BYD headquarters building located in Longgang built to further enhance the its core brand values.

At present, BYD has been in the Baolong Industrial Zone, more than 60 million square meters of factory park is preparing for the construction of a new park planned area of 50 million square meters, the base to start after the completion of its new energy vehicles in the core of power technology part of the iron battery.

“Product In addition to the supply of BYD’s own electric car, there will be the Mercedes-Benz, Volkswagen and SAIC global auto giants such as new energy automotive supply, output is expected to reach billions of dollars.” Relevant person in charge, according to BYD , iron battery is BYD new energy automotive industry in the core technology in a new part of the upstream energy industry, electric vehicles and energy storage power station will be the basis. After the completion of the project will be the BYD Baolong Industrial Zone, across the country’s largest iron battery production base, but also will become the world’s largest automotive battery with a new energy production base.

“The new industrial zone construction standards will be comparable to build a new city.” According to reports, in Longgang District, the growing scarcity of industrial land, the BYD new park’s construction will follow the principle of intensification, in accordance with high standards of a modern industrial park to construction, Baolong Industrial Zone and will be the landmark, thus enhancing the image of the entire industrial area.

Iron battery

Study at home and abroad-iron battery has a high iron and lithium iron are two kinds of BYD-iron battery for the former, in addition to BYD is currently no other manufacturer outside the large-scale mass production and practical use. High-iron battery is the energy density, small size, light weight, long life, non-polluting new chemical batteries, with a high-energy high-capacity, rich in raw materials, green non-polluting and so distinct advantages.

A few years ago, BYD on the organization of R & D team of 500 people began the iron battery research and development research. After tens of thousands of trials and testing, successfully developed a dedicated iron battery electric car, named “ET-POWER”. It is BYD’s latest research results in the battery.

Apple has once again brought a new crisis in consumer electronics.

Jobs bring new again, Apple fans waiting, each time, Steve Jobs holding the hands of the product have been given Steve Jobs’s innovative spirit, giving people unlimited reverie, but this time not the same.

iPad appearance is a Tablet PC, just belongs to notebook category. However, it is extremely light weight, use the iPhone (mobile Internet) operating system, from the perspective of these characteristics, iPad seem to be in smart phones, e-books between the reader and the Internet present.

“From the features, product design, software and content terms, iPad fulfill all the promises,” iSuppli’s senior vice president of DaleFord said, “It is only 499 U.S. dollars initial price of the product even beyond expectations. However, due to iPad across multiple product areas, and its actual usage patterns have not yet been verified, it may be several quarters in the ship, we will know whether the product will revolutionize the industry, the impact of science and technology. ”

This suspicion is not without reason, the screen can be rotated, you can pen-based tablet PCs are nothing new, Dell, Lenovo, Acer Yang had already introduced such a computer, but not yet caused any reaction.

Today, only because it is Apple’s name?

Yes, if the iPod, iPhone, past record of any reference to meaning, consumers may still find their lives very difficult to leave the iPad.

However, such rules of the game is being broken.

Prior to the iPhone, people are concentrated in demand for mobile phone calls, send text messages, take pictures, listen to music, these “hard” indicators. Starting from the iPhone, people began to realize: the phone is now able to have so many day games and various related applications.

In theory, iPhone can be achieved visit www pages, but the traditional wired Internet access can not be applied mechanically moved to the phone, but also, 3,5-inch screen, still limit the integrity of the web page rendering, clever Jobs cleverly set up on the AppStore , “iPhone10 million applications can do almost anything.” iPhone in the advertisement boasts Road, these applications designed specifically for the iPhone, even though three years ago, iPhone is not a multiplicity of species, without changing the performance, but also to an increasing number of consumers willing to draw a good circle in Apple games , recreational pay. It now appears that the iPhone greatly reduced arcade sophisticated trend.

But along with wireless Internet matures, Jobs set up the closed rules are being challenged, bear the brunt of the challenger from Google, “i-Phone no real keyboard … … can not run multiple applications at the same time … … can not shoot 500 megapixel photos … … … … does not allow opening up and development is not interchangeable battery, “Google said in the advertisement, and at the end states,” iPhone can not do any thing, Android have done it. ”

In relation to Apple’s closed, Google is free and open to attract large crowds, Google chief executive Eric Schmidt said: “An-droid manufacturers using the number of really imminent explosive growth.”

Shenzhen mimic those highly talented cottage manufacturers crazy, and if the wireless Internet to everyone with open arms, why should we crowded in the AppStore a small world? No matter what Apple has developed products, these cottage manufacturers can keep pace with rapidly within 3 months.

The iPad is breaking its own restrictions on the small screen, 10-inch screen is the mainstream of the Internet in this configuration, it can always log on www to find anything you wanted, where there are 100,000 more than just applications.

Apple wanted to use iPad to inspire a new user behavior and the new usage patterns in order to try and create a new market, but we can see is likely to iPad and professional markets, where many existing products to compete, such as e-books , Tablet PC, and PMP/MP3 player.

Despite the future, because of the ubiquitous network, people need to jump between screens of different sizes, but the iPad would like a computer, cell phone, as a people’s “necessary”?

The iPad simple lines behind the technology of today’s Steve Jobs control, aesthetic vision, and marketing can be able to shine again?

Credit Suisse analyst Jonathan Chaplin (Jonathan Chaplin) Thursday, said Apple may not give up this year, with AT & T’s exclusive cooperation agreement.

Apple and AT & T’s iPhone exclusive cooperation agreement is expected to expire in June this year, the industry generally believe that Apple will be the end of an exclusive partnership and cooperation with Verizon.

However, Chaplin said Thursday, Apple continues to work with AT & T this year, the possibility of cooperation as high as 75%. This means that at least 2010 years, Apple has not been possible hand Verizon.

Chaplin said: “There is no definitive evidence that Apple and AT & T’s exclusive co-operation agreement will expire this year, this possibility is 50%. In addition, AT & T requested the possibility of renewal of 25%.”

Chaplin believed that if it continues to cooperate with the AT & T exclusive, in 2010 in the North American smart phone market, Apple’s share of 26% from 2009 down to 23%.

Chaplin is expected, Verizon is expected to get iPhone in mid-2011 mid-term contract.
