Cheap charger is damage, cell phone power management need to be cautious B

ON Semiconductor vice president of sales Lin Jianming China: the near future, sales of mobile phones and adapters will be completely separate, which will pose a mobile phone side of the test charge.

Lin Jianming: If there is no perfect internal overcharge protection circuit, the battery will overcharge may cause an explosion of serious consequences.

Charging the phone interface, over-voltage is undoubtedly the most dangerous. Poor quality in the adapter, failure or user error then a different device adapter can happen. In general, your phone charge management IC can control the charge current and voltage, to maintain the security charge the battery. However, if the rated current of the input voltage is too high while charging, over charging management circuit can withstand value, the circuit components will be adjusted because of charge-off or burned out of control power and role. The worst case, at this time if the user also uses low-cost lithium batteries, could not complete overcharge protection circuit, the battery will overcharge may cause serious consequences of such an explosion. To this end the provisions of the phone in YD/T1591-2006 in the side to contain over-voltage protection circuit to prevent such from happening. Overvoltage protection (OVP) circuitry detects over-voltage fault conditions, the detection circuit will be switch off, disconnect the phone and the adapter output.

Power Management Products National Semiconductor Senior Application Engineer Zhongjian Peng: charge management circuit functions normally charge by the management of single chip (Charger IC), or integrated charge-management functions of power management chip (PMU) to achieve. Rechargeable lithium battery management circuitry to support features for the trickle charge, constant current charging, constant voltage charging of the three charging process, and should have protection mechanisms to prevent overheating. Advanced charge management circuit also should have the input voltage over-voltage protection function. The protection of the safety of the product itself is very important. Some unqualified charge management circuit, often lack the protection of the design, the circuit itself may cause damage to the system overheating, or even more serious security issues.

MPS Marketing Director Yuan Wenlin Asia: a new generation of rechargeable IC PMU have in addition to charging function through the highly integrated hardware to achieve high reliability, but also should have OVP (overvoltage protection), OCP (overcurrent protection) , NTC function, both a high input voltage, small size and simple external circuit. USB charger for battery management IC should be consistent with low standby power / charge current programmable switching / charging mode multiple input / can set the input power charger or USB port, and automatically charge the battery and cell phone distribution work be current; and in accordance with standard USB port of the limit.

Excellent cost-effective chip Recommended

Power Integrations’s primary regulator device, such as LinkSwitch, can maintain the electrical insulation, and does not require optical isolators in the case of feedback to provide precise output voltage. This can reduce costs, help design a smaller charger, while maintaining the necessary security clearance.

The latest LinkSwitch-II products with accurate voltage control, can be very accurately simulated USB port. In addition, the products include cable drop compensation, so regardless of cable above the extent of the loss of current, voltage can be kept constant.

LinkSwitch-II 5% voltage accuracy, current accuracy of 10%, for the adapter and charger is ideal. Also, it requires 20 components to build a complete AC power, which saves the cost of components itself, but also saves production time, assembly and inventory costs. “In China, labor costs have increased to around 0.003 U.S. dollars each component cost, for small patchy resistance and capacitor to say, in the cost of Shangzhangfuduo Gengda.” Doug Bailey of Road.

MPS full range of battery charging chips are produced using high pressure technology, have a minimum 20V, maximum 28V of voltage, and have been integrated over-voltage protection and meet the low standby power requirements. To comply with USB OTG low standby power requirements, a new generation of MP-2605X series also will reduce the standby current to 40uA, and increase the reverse input voltage protection (-16V) function, following the industry MPS charge chips widely used:

MP2605 standard charge applies to all chip general hand-held portable devices; MP26056 support USB / adapter pair of input interface for USB interfaces need to charge the portable device; MP2607 built pwr path, can be automatically assigned to charge the battery and the phone work current required for high-end hand-held portable devices such as smart phones, GPS navigation, PDA applications.

“Based on customer feedback, they are using MPS of charge chips, the great majority Yin Wei cost considerations Ercai Yong PMU / single chip charge management, but only to find defects line charge account all Ke Fan Xiu back the number of more than 20%, but cause the overall cost increase; but wants to be using external components to enhance the safety factor PMU, the additional cost and board area, also makes the industry difficult to sustain. At this point if the use of MPS battery charging chip, cost and product quality can be strikes a balance. “Yuanwen Lin said.

TI’s bq24070 series and bq24032A series provides a separate charge path and system power path, effectively prevent the repeated charge and discharge system problems, battery life is greatly extended; resolve the cell phone a full charge the battery consumption issues began to extend the standby time 10 ~ 20%; effectively prevent the system out of control due to CPU crash and the risk of charge, to prevent the result of external pressure and breakdown voltage over the issue, greatly increasing the reliability of the system; eliminates the additional over-voltage protection, and path switching MOSFET and Schottky diode, reducing total system cost. The adapter current consumption in the system and charge redistribution between the automatic on-demand, using a small adapter, but greatly accelerated the charge time and reduce costs while improving the user experience.

“TI advocates the path of dynamic power management in battery power management applications has been recognized by customers, such as dual-port (USB, AC adapter input, respectively) linear charge management chip bq24032A series, single-port bq24070 Series (USB, AC adapter to share an input), “Zhang was said.

ON Semiconductor has introduced a series of overvoltage protection chip. AC adapter for wall charging plug the NCP347/348, can provide up to 2A of charge mobile phone current and voltage transients up to 28V fault protection; NCP360 and NCP361 USB interface, suitable for positive over-voltage protection controller, with very low 35µA current consumption to meet USB standby requirements, NCP361 also has a current limit function; to meet the cell phone charger / power supply to accessories such as the demand for bi-directional current control, ON Semiconductor also forthcoming NCP370, provide ± 28V overvoltage protection and adjustable current limit.

SGM4054 as St Microelectronics state management in charge introduced the first product has now passed the test in a variety of applications and high-volume applications, the main features include: programmable charge current up to 800mA, high-capacity battery can achieve the fast charge; heat calibration can prevent constant current, constant voltage operation mode, the battery overheating and improve the safety of consumer products; by USB directly to a single battery charge, to meet the multi-product compatibility; with charging indicator, providing the user identification information; 1% charge precision, to ensure battery life; low shutdown current of 25µA, promote the effective utilization of power; own 2.93V trickle charge threshold, rechargeable lithium battery can be fully consistent with the standards process (trickle charge, constant current charging, constant voltage charged off recognition); with automatic recharge feature, to provide sufficient energy. Follow-up will launch high-pressure, high charging current of charge management chip, to meet the new demand for mobile phone application for more power.

National Semiconductor for different applications-rich charge management solution. A single chip charge management chip (LM3658), support for USB, AC-DC regulator of two inputs, and have overheating protection. There are many highly integrated power management chip (PMU) has well-integrated charge-management functions. Such as GPS, PMP designs PMU LP3913, the integrated support for USB, AC-DC regulator of two input and support of the charge current path management snap. There are many applications designed for mobile phones PMU as LP3919, more up to 28V overvoltage protection.

Honda and GS Yuasa

Honda president described a joint venture with GS Yuasa lithium battery development to promote the whole story

Honda and GS Yuasa (GS Yuasa) announced that they have to set up a joint venture of lithium-ion rechargeable batteries have reached a basic agreement. Honda president Takeo Fukui said at a press conference, "in the current critical situation, to further accelerate the development of advanced environmental technologies, and offer attractive merchandise to customers is the key to survival." Fukui and GS Yuasa explains the common reasons for setting up a new company, and pointed out that the short term will not change the number of battery suppliers to the situation; GS Yuasa frankly stated that the new president Yi Tian Cheng and GS Yuasa joint venture with Mitsubishi joint ventures do not conflict, and is expected to achieve synergies.

Q: When will the new lithium battery, at what scale production? The current investment amount? Want to first apply to the new lithium battery which models? Toyota and Panasonic have set up a joint venture company "Panasonic EV Energy" Ltd., Nissan Motor and NEC has also set up "Automotive Energy Supply", Honda's action seems a bit late. This new company will be inherent?

Fukui: investment, the Honda plans 15 billion yen investment (about 168 million U.S. dollars) for about half of the registered capital. Since the spring of 2009 in Japan, North America and European launch of the new hybrid Insight uses nickel-metal hydride rechargeable batteries and other reasons, it is hard to say please a new battery production time and application of models, but we will put into operation as soon as possible The goal, I believe that we will not fall behind other companies.

Reporter: When to start thinking about setting up a new company? In addition, Honda had a number of supplier companies are purchasing from the battery, after the establishment of the new company is to plan it? Consider whether lithium batteries for fuel cell vehicles and other environmentally friendly car?

Takeo Fukui: Honda of many programs in recent years. And GS Yuasa battery business, beginning a few years ago has carried out its business in the lithium battery. In addition, the latest "ASIMO" is used to provide a dedicated GS Yuasa lithium heap. If farther back, motorcycle batteries is our common and GS Yuasa joint development, the two companies have business dealings from the early years. About setting up a new company from 1 year ago (late 2007) began to discuss specific issues. The just released in such an environment, we did not expect the global economy should there be such a big change, but even if the financial crisis will not occur at this time announced.

About the future business development, we plan to be the initial stage of hybrid system for the Honda "IMA (Integrated Motor Assist)" as the goal of promoting cell development, the project will have the exclusive products in a short time to develop. After that the business will be done in consultation with GS Yuasa.

In addition, the currently used nickel metal hydride rechargeable batteries from Sanyo and Matsushita purchased the two companies, and will continue to purchase from the two companies.

The original intention of the new company's goal is the achievement of course, the competitiveness of the world's first commodity, but one of the joint venture partner Honda will still be the battery buyers. Honda will be on the Q (quality) C (cost) D (delivery) decided to assess whether the joint venture to purchase the battery products. From the results point of view, if the new company all products (lithium batteries) can be used by Honda, it certainly is the best.

Q: Honda has repeatedly said earlier, the technology is still in the process of development of the car battery, the best purchase from a number of companies. To wait until the future prospects, and only after a look at a company. The cooperation with GS Yuasa mean that the technology landscape is clear?
Fukui: Generally speaking, the current battery there is still much room for development, I think the future may also be many new concepts battery. While looking forward to this, but the most practical solution at this stage, or lithium batteries, therefore, we believe that battery manufacturers and automotive companies to develop is the fastest way to implement goals.

Reporter: GS Yuasa and Mitsubishi Motors has been with Mitsubishi formed a joint venture company "Lithium Energy Japan". How do you intend to approach to distinguish between the two (joint venture) company's battery development?

Yi Tian Cheng: The new company set up with the Honda hybrids will be lithium battery research and development and production and sales of the company running. The Lithium Energy Japan is engaged in electric cars lithium battery business of the company. Product line is obvious. Of course, a clear division of the company will also develop, manufacture and development of production sectors. But the long view, many are expected to achieve synergies.

Reporter: GS Yuasa how to treat a number of car manufacturers and the strategy? In addition, just now you mentioned that a clear distinction between use and hybrid electric vehicles using lithium batteries, exactly where the difference between the two?

Yi Tian Cheng: electric vehicles and hybrid vehicles with lithium battery manufacturers are not separate from the development, and then to the car manufacturers "use" of goods. But should be on the car's driving pattern and configuration and other conditions were "special order." In other words, the battery will start from the design stage in consultation with the automotive manufacturers, and must be jointly developed by both products. Accordingly, the Company jointly set up the production of hybrid and Honda's new lithium battery is an inevitable trend. Of course, the future may arise due to the changing times in different ways, but at this stage with the Honda or Mitsubishi Motors to jointly develop the most natural form.

In addition, hybrid electric vehicles using lithium batteries used and the difference is that the former only the battery power source, so battery capacity must be larger. Which the power source for the battery and engine, so no great capacity, but because the output power during acceleration and deceleration of the electric power regeneration, to be very frequent charge and discharge. Therefore, the hybrid with a lithium battery capacity is small, but it must be good for the battery charge and discharge performance. These factors determine the content of their development are different.

Reporter: Honda may also take stake in GS Yuasa method. Why choose a joint venture?

Fukui: I think there is not much meaningful stake. In addition, the establishment of a new company in the battery business, so by holding the battery manufacturer GS Yuasa most, holding a small semi-Honda is the best form of joint venture (joint venture production time to prepare for the spring of 2009, is headquartered in the GS Yuasa Kyoto headquarters, the site also GS Yuasa Fukuchiyama mayor of the field-cho production base, holding the ratio of GS Yuasa 51%: Honda 49%, the joint venture's business is described as "lithium-ion battery production, sales and R & D "- Editor's Note.)

Reporter: Panasonic acquisition of Sanyo Electric to bring the new company set up what are the implications?

Fukui: I see by the newspaper on the Sanyo Electric Matsushita implemented TOB (the stock tender offer) of the message. GS Yuasa and we long ago began to consider setting up a new company. Therefore not affected.

Lithium Battery Energy saving Upsurge

With the constant fluctuations in international oil prices, energy saving environmentally friendly lithium battery in the limelight once again a hot topic. From 6 months, the number of international auto companies and electronics companies are using large-scale lithium battery joint investment. Including Toyota and Matsushita, Nissan and NEC, Volkswagen and Sanyo, Bosch and Samsung, they believe that lithium batteries in the next few years will gradually replace the nickel-metal hydride batteries, lead the direction of development of hybrid vehicles. Li-ion battery in the heat of global investment background, China's automotive enterprises in this research work is in what kind of? Experts on the lithium battery is holding what kind of attitude? Recently, the reporter interviewed specifically on this issue who has studied the domestic lithium battery, several experts.

Beijing Institute of Electric Vehicle Engineering Center Deputy Director Lin Cheng

Study of lithium iron phosphate has been a breakthrough

Lin Cheng told reporters, demanding automotive lithium batteries. It requires that the vehicle used in a variety of conditions, must protect the security, can not occur fire, explosions and other accidents. The first was for battery electric vehicles, in this country has made great breakthroughs have begun to take industrial scale. But 5,6 years ago, with the battery powered vehicles are often some accidents, such cells will gradually be diluted. Now, the domestic lithium battery research progress quickly, especially in the battery safety issues, has made great progress.

Lin Cheng told reporters, lithium batteries include lithium manganese oxide and lithium iron phosphate batteries. At present, the development of the domestic lithium manganese oxide has begun to take shape. Lithium iron phosphate as safer, longer life, will become an important direction for future development of lithium batteries, but also abroad, the focus of research and development of the automobile. At present, lithium iron phosphate studies of good progress, especially in some of the patent on a breakthrough, this time for the Beijing Olympic Games is a passenger car with a self-developed lithium iron phosphate lithium battery.

"Of course with the study abroad compared to lithium batteries, the domestic lithium battery research still lags far behind, but the domestic lithium battery emphasis on increasing, the future will be the R & D focus." Lin Cheng told reporters.

Henan Huanyu Group lithium battery industry technology Deng Lun-ho, deputy chief engineer

Large-scale lithium batteries for electric cars need some time

Henan Huanyu Group is a component from the battery to the battery cell manufacturing plastics and related hardware, equipment manufacturing, electronics manufacturing, a complete industrial chain of the Enterprise Group, has undertaken the project of Science and Technology Li-ion battery research and development.

"At present the domestic lithium battery research and abroad, the gap is mainly reflected in the battery control system and power management systems." Deng Lun-ho told reporters that now the domestic lithium battery research for development in their respective state. Currently, some companies have been able to provide the corresponding lithium battery electric vehicle accessory products, supporting the general lithium batteries can run 200 to 500 km.

Deng Lun-ho told reporters that now the price is too high the domestic lithium battery, power management system problem has not yet been well resolved. Charging electric vehicles also face the problem. Currently, the general line at home can not charge lithium batteries for electric vehicles must be equipped with a small dedicated charger, and charging time is very long and very troublesome. Abroad, in order to solve this problem, generally regarded charging stations and gas stations together. China is now charging stations have not established a large scale.

Deng Lun-ho believes that the current consumer acceptance of electric vehicles equipped with lithium batteries it still more difficult: "the price of an ordinary electric car is about twice the same configuration or even higher gasoline locomotives, domestic consumers have not enough economic prepared to accept the power and electric vehicles. "

China Electric Power Research Institute engineer Chuang Feng

Optimistic about the prospects for the development of lithium iron phosphate

Chong Tong, told this reporter, the electric vehicle battery research and development work has gone from lead-acid batteries, nickel-metal hydride batteries to the development of lithium batteries, each battery advantages and disadvantages.

The earliest to appear in lead-acid batteries, used in the longest time, belonging to the battery series. The best safety performance lead-acid batteries, rare explosion, fire and other phenomena, energy storage effect is not ideal. Later, people developed a nickel-metal hydride batteries, store energy and power than the effect of the ideal lead-acid batteries, but due to nickel-metal hydride battery in the charging of hydrogen generated in the process prone to explosion, so the nickel-metal hydride batteries in a business may or may not state.

To the year 2000, people developed a lithium battery. Lithium batteries are lead-acid storage battery of power 2 to 3 times, but because it contains lithium-ion active in the metal layer surface, prone to spontaneous combustion in the air, explosions, etc., higher risk. So now the major countries is to control the development of lithium batteries is safety and stability.

"Charging a lithium battery would be able to cycle around 1000, in which the stored energy of lithium iron phosphate is better than lithium cobalt oxide and lithium manganese oxide effects worse, but it's the best safety performance, than lead-acid battery energy storage much higher, so now the most promising lithium iron phosphate. "Chuang Tong said.

Society of Automotive Engineers of China, director Chen Quanshi branch of electric car

Three problems of domestic lithium battery research

Quan-Shi Chen said in an interview: "Now the state attaches great importance to the study of lithium batteries, '863 'project, the state invested a total of 66 million yuan, all development work for the lithium battery. We and Japan, the United States such as walking in the lithium battery research and development in the forefront of the developed countries, China's lithium battery manufacturing precision, equipment, standards, etc. there is a certain gap between R & D details. "

Quan-Shi Chen told reporters that at present there are three issues of domestic lithium battery research. The first is the consistency of manufacturing. Since the lithium battery manufacturing technology and equipment there is a gap, the domestic lithium battery production technology mixed, manufacturing standards has not yet reached agreement. Lithium batteries used in electric vehicles are connected in series or in parallel, if the consistency issues are not well, then the large-scale production of lithium batteries used in electric vehicles will not be able.

Followed by the intellectual property rights. Currently in the study of lithium iron phosphate has made a breakthrough, but the U.S. patent in this area, so although some of our links to independent research and development, but in intellectual property issues, but also do not know how to respond.

The third issue is the selection of raw materials. Now the production of raw materials used in lithium batteries can not all imported, mainly from China, but domestic raw materials, through international certification, to produce lithium-ion batteries in order to be internationally recognized, so the link in the certification of raw materials and also some problems.

Buffett's largest battery manufacturers Nuggets storm

Subject to further deterioration in U.S. subprime mortgage crisis news, global stock markets plummeted again, almost all of the investors are confused and do not know how to develop late, and which concern the industry, this time, "Warren" Buffett once again shot for specified investors the future direction of investment. Hong Kong-listed BYD at the opening day last week, rose 90%, almost double! The reason is that Warren Buffett invested 1.8 billion Hong Kong dollars acquisition of China's largest rechargeable battery maker BYD stake of 10%! Currently, the market authority generally agreed that the field of BYD electric vehicle battery technology leading the main advantage is one of Buffett's shot. It is noteworthy that, in Buffett's BYD to attract investment and short-term stimulation soared, A-share market after the opening bell on Monday to Section power far, Desai batteries, battery, led by market trends limit the outbreak of the collective subject shares , one of the few bright spots the market. Their common characteristic is the same as the production and BYD car battery! After careful excavation, we found (000,839) CITIC Guoan: The company is the largest lithium battery cathode material of lithium cobalt oxide and lithium manganese oxide manufacturers, but also the only large-scale domestic production of lithium ion secondary battery manufacturers, Power Battery Company has been identified as the 2008 Beijing Olympic Beijing Olympics pure electric bus exclusive supply products, we can see whether a product or a scale far better than the BYD, Section Desai battery power far and is worthy of the name power battery industry leader, therefore, short-term effect in BYD under battery power crazy, and Buffett's long-term gold investment philosophy is driven, we have reason to look forward to CITIC Guoan up the outbreak of the future will continue to strongly recommended that investors pay close attention!

Buffett storm Nuggets, car battery to prominence!

In a jittery global financial markets when, "Warren" Buffett once again dished out generous, indicating their car battery industry is very promising. Authoritative analysis revealed that Buffett will focus new energy battery new energy industries, especially the nickel-hydrogen batteries for automobiles into a stimulant. BYD resumption of trading last week after Hong Kong stocks, the stock doubled in 3 days, attracting the attention of the world. In addition, the National Energy Research Institute Master Ren Gaoshi constitution that the Government to promote and encourage the development and utilization of new energy policy will not change. This means that the growing tension in the energy and long-term trend, domestic battery and other items with the listed company full of bright prospects for development. And because of this, A shares within the first trading day National Day Return staged a crazy battery subject shares soaring drama, we see a continuous plummet in Shanghai and Shenzhen panic atmosphere, with car battery Aspect of the Division real force far stronger limit Desai batteries, such as production Fosugufen related materials are nickel-hydrogen battery to soar! We note that the focus of BYD soared because of its battery Aspect, A-share market is currently involved in the field are not many listed companies, only a few have a true sense of the power battery products projects. This background, as a real car battery Aspect (000,839) CITIC Guoan is unknown at present, there will be a blockbuster material afternoon soared good show!

The largest battery manufacturers, the industry leader!

CITIC Guoan MGL (referred to as MGL) CITIC Guoan Co., Ltd. is holding 90% of the subsidiary. MGL was founded in April 2000, mainly engaged in the lithium ion cell materials and high energy density lithium ion battery research and development, production and sales. MGL is currently the largest lithium battery cathode material of lithium cobalt oxide and lithium manganese oxide manufacturers, but also the only large-scale domestic production of lithium ion secondary battery manufacturers. After nearly a decade of efforts, MGL has developed into a business involved in technology development, production and sales and investment and other aspects of comprehensive large-scale high-tech enterprises, and formed from the lithium battery materials and lithium batteries to electric vehicle research and development and production complete industrial chain. MGL power lithium battery for 5 consecutive years by a national authority comprehensive security and performance testing. Outstanding safety performance of the product, MGL developed high-capacity lithium manganese battery by the Beijing Organizing Committee for the 2008 Beijing Olympic Games to determine the pure electric bus exclusive supply of products. Requirements under the Beijing Municipal Science and Technology Commission, CITIC Guoan MGL Power Co. electric car project for the Beijing Olympics provided 100Ah high-capacity lithium manganese battery loading has been running for more than 10,000 km, the battery in good working condition. It is reported that electric bus charging time is short, 3 hours to reach 95% charge level, charging each one to run 200-400 kilometers per charge and 500 times the battery capacity will decay by 8.3%, its operating cost is only fuel vehicles 1 / 5. Lithium manganese oxide as cathode in the large-capacity secondary battery power, is expected in the future will quickly be applied to the land, sea and space and other mobile power, emergency power, uninterrupted power supply and large-scale power storage device in the city at night. CITIC Guoan MGL Power Technology Co., Ltd. has developed several hundred to several kilowatts of energy boxes of new products, take advantage of non-renewable energy create a new way. It can be seen, as with BYD's battery, the company's battery subsidiary and use the product even better, and many other aspects, which had people on the CITIC Guoan is more optimistic about future prospects, a real The industry leader!

If you are confused to believe that Buffett's eyes!

In a jittery global financial markets when, if you lost to believe that Buffett's eyes! God shares the success rate of at least much higher than other institutions, so time and time again history proved Buffett's unique vision. Market, the Hong Kong-listed BYD opening day or 90%, almost doubled; A-share market point of view, with real car battery Corun Aspect, Desai batteries continuous limit, such as production Fosugufen nickel-hydrogen battery related materials are substantially higher. This background, we believe, CITIC Guoan is the largest battery manufacturer, the company battery is identified as the 2008 Beijing Olympic Beijing Olympics pure electric bus exclusive supply products, we can see whether a product or size are much much better than BYD, Section power far and Desai battery, battery power is truly the industry leader, the bottom of the stock price is still in the history of power sector will attract the coveted. Technically, the stock adjustment in place, is expected to strongly broke up late, it is worth investors to pay attention!

Paralyzed man can again "talk"

U.S. researchers have a completely paralyzed man returned a piece of his linguistic abilities. Thanks to a speech used in the electrode, the patient can produce more than one computer three vowels - as he thinks of the lute.

The man suffers from a Locked-In Syndrome. Normally, people can move up to their eyeballs with this syndrome or eyelids, and communicate so that neither muscle contractions even over their vocal apparatus. With the new system had now been constructed for the first time an interface between the brain and electronics that converts brain signals directly in language, study leader Frank Guenther of Boston University reported at the annual meeting of the American Society for Neuroscience in Washington.

Most brain-computer interface (BCI) detect brain waves through electrodes that are placed outside the skull. They are currently used primarily to enable people after the loss of limbs a mental control of their prostheses and to give a lame way to use a computer cursor. However, at this system, the electrodes move quite easily - with the consequence that they measure the wrong signals and the BCI to be recalibrated.

Because Guenther and his team, however, wanted to permanently absorb the impulses, controls the speech with which the vocal tract, they implanted their patients an electrode directly into the appropriate brain region. The part was so impregnated, that it promoted the growth of nerves and a long and more firmly anchored in the brain.

After surgery, the researchers in the subjects specifically thinking about certain vowels, and drew attention to the signals recorded by the electrode. This was then fed into a computer with a connected synthesizer and associated with the vowel. In this way produces the computer every time the man thinks about an "A" without delay the sound "A".

Meanwhile, the patient thus already three vowel sounds create a high accuracy and a speed equal that of normal speech, reported Guenther. Long-term - estimated in the next five years - is the subject learn to produce consonants, and these combine with the vowels to complete words. Guenther also hopes to record in similar cases in future, thanks to enhanced technology more details of brain activity to be able, for example by the transplanting of several electrodes.

Apple CEO wants his rest

Apple CEO Steve Jobs wants to do, despite the claims of investors and industry experts, no further details about his health. "Why do you guys let me in peace - why is this so important?" Jobs said in a rare interview.

To have the health of the 53-year-olds for months much attention because he is regarded as the driving force behind the success of the computer and iPhone manufacturer Apple. Jobs announced a few days ago that he would take a break because of his health problems until the end of June, as the treatment is more complex than first thought. According to recent information he is suffering from a hormonal disorder.

The financial news agency Bloomberg, led the interview with the jobs reported, also citing people that Jobs' health watch ", of consideration of a liver transplant. It remained unclear, however, whether it's about people who actually are familiar with the disease of the Apple boss, or to experts who analyze his condition remotely.

After Jobs' information prevents the hormone disorder because his body to process proteins, making it lose weight. In 2004, Jobs was due to a cancer tumor, had surgery on the pancreas. It was modified several times, he did not have cancer.

Since June 2008 the first time noticed the weight loss of jobs, the information from Apple is criticized. The company was making a slow and only very general information about Jobs' health. Many investors and industry experts are calling, however, that Apple fully informed, given the prominent role of the co-founder of the Group's business on his health. In this context, shareholder suits are not excluded. The constantly emerging speculation about Jobs' health had impacted the price of Apple shares in recent months strong.

Jobs is like no other U.S. managers as a motor and guarantor of the success of his group. Apple's triumph in recent years with products like the iPod music player and iPhone mobile attributed to a large job. He will remain involved during the time out on important strategic decisions, the charismatic corporate executives said several days ago. He will be soon be re-elected in the Board of the Disney Corporation, where he has been the sale of Pixar Animation Studios has a share of 7.5 percent.

In the coming months is to Tim Cook, Apple's take on the reins. Cook is considered one of the main architects of the economic success of the computer and iPhone manufacturer. As for the daily business responsible, "Chief Operating Officer, he ensures that after the implementation of bold visions at the end of the day in the black are in the books. And with success: Apple is sitting on cash reserves of almost 25 billion U.S. dollars - with no debt. The U.S. magazine Fortune recently paid tribute to Cook as "the genius behind Steve. The next few months would show whether the 48-year-old Cook had grown too long, perhaps the chief role at Apple.

Jobs took the Compaq-manager in 1998 for Apple - and Cook took on the then-struggling company by quickly with efficiency. He closed his own manufacturing plants, Apple, and put on contract manufacturers. He left the stocks of months melt to days. The Apple later helped again and again to have lying around in the fast model changes in the electronics industry does not run as legacy devices. Cook the same time ensured smooth delivery of the various products. Most recently he was responsible for the lead among other business with the success of the iPhone mobile phone.

Similar to the 53-year-old Cook jobs is regarded as publicity-shy workaholic who sends e-mails and sometimes in the middle of the night - and often as difficult to work with. Cook's management style illustrated by the following anecdote from the Fortune 90s. Apple Cook-Manager advise about a problem in Asia. "That's bad, he says. Someone should be immediately worry about in China. "Half an hour later, he looks one of those present in the face and asks:" Why are you still here? ". The manager goes directly to the airport and buy a ticket without a definite return date.
