Microsoft is investigating the possibility of Xbox 360 game consoles of the type to use in hospitals. There they could read electronic patient data and filter and make it visible on screens in the hospital room for nursing staff and patients. This has Microsoft announced at an event of its Health Care Division Health Vault in Beijing.

Microsoft engineer Desney Tan that the consoles are cheaper than those usually used for that purpose hardware. In addition, patients could be playing or access the Internet – possibly with gestures on the next input system Natal.

Microsoft’s health services are developing also in other directions. So will you give patients the tools with which they identify their calorie intake by cell phone or count their steps. They too should be able to easily access their medical records. MyLife thus uses the tool that runs on Windows Mobile smartphones, embedded devices such as cameras, motion sensor and microphone to capture data such as blood pressure or weight and to log activities such as sports and eating.

Eric Chang, manager of Microsoft Asia, says he dream that users retrieve information about their food – calories, nutrients contained, risks for allergy sufferers – because of a photograph could. As a first step, he imagines tags, which could provide themselves food. It is natural for plants from the garden, hard by a farmers market or grocery store. But if there is no other just as McDonald’s dining area there, the user can then at least monitor the deterioration of his physical condition.

Intel has expanded its portfolio of Solid State Drives to an entry-level model called X25-V. This is a stripped down version in July 2009 announced the X25-M series with 34-nanometer NAND flash memory. The SSD is available now at a price of $ 125 on the market.

The 2.5-inch X25-V model is working with MLC memory cells and a SATA II interface. It offers a storage capacity of 40 GB. The read speed is up to 170 MB/s slower than achieved in the X25-M series, the read rates of 250 MByte/sec. The maximum write speed of 35 MByte/s – half of the achievements of the X25-M series value.

The mean time between failures (Mean Time Between Failures, MTBF) is Intel, with 1.2 million hours (136 years). The Sto?resistenz maximum of 1500 G. In operation, the drive consumes 1.5 watts. At rest, it is content with 0.75 watts. In addition, dominates the SSD which is supported by Windows 7 TRIM command, which ensures a consistently high level of readiness to perform a Solid State Drive.

Without TRIM support for SSDs can use the service after a prolonged partial decrease considerably. The reason for this lies in the physical properties of the flash cells. Flash memory can be described only with no wait states, if the cells are empty. Since the operating system files but only delete the contents of the file system and the controller of the SSD of this deletion will notice anything, it must delete the access back into the cell, these first before he can describe it. Per TRIM command divides the operating system with the SSD controller, the data blocks are no longer used, so that it can delete the unused cells of rest, in order to later describe without loss of performance again.

Kingston sells under the name V SSDNow an identical model of the Intel SSD. A similar review is available here.

Intel makes 32-nanometer CPUs for servers and workstations

The chip manufacturer provides 15 models for 2P systems and one for 1P systems. There are four and Sechskern models available. The thermal design power is between 40 and 130 watts.

Business brands: Acer Battery , Apple Battery , Fujitus Battery , Lenovo IBM Battery , Sony Battery , Dell Battery , Toshiba Battery , etc.

Intel brings out today, the first Xeon processors that are manufactured in 32 nanometer technology. In the market for entry-level servers with a CPU, the chip manufacturers come up with only one model (W3680). The Xeon-W3680 CPU is completely identical to the desktop Core i7 processor-980X, which ZDNet has been tested extensively. Intel only uses different model names for the server and the desktop market.

For servers and high-end workstation with two CPUs per motherboard Intel CPUs offers of 15 different series Xeon 5600 (Westmere-EP on). Depending on the frequency, number of cores and power consumption of the list price from 387 to 1663 dollar is at a 1,000-unit quantities.

All models are based on the Nehalem architecture with integrated triple-channel DDR3 memory controller and QPI. The instruction set was extended by an AES hardware encryption, which can achieve a speed up by about a factor of 15.

One exception is the L5609 dar. He no hardware encryption still turbo-boost and hyperthreading dominated. All models are equipped with 12 MB L3 cache. In addition, each computer core 256 KB L2 cache and exclusively used every 32 KByte L1 cache for data and program commands.

For the first time is it in a series no clear top model: the X5680 CPU has six cores and is clocked at 3.33 GHz. The model X5677 contrast, has only four cores, but can come up with a 3.46 GHz clock frequency. Applications that are not in a server with two processors of more than 16 processor threads can benefit run faster with the X5677 with the X5680. Both models cost $ 1,663.

The top two models require 130 watts TDP. The most fuel-efficient models come with 40 watts. For six cores are needed, however, at least 60 watts.

This is the Buck ball of 60 carbon atoms. This great ball can store a number of atoms in the internal sphere, including hydrogen.

Yakobson recognition, to store hydrogen in a long time the idea of molecular container. Rather, the bucky ball to accommodate the idea of hydrogen already known in the past had.

However, Yakobson, there are others before Olga Pupysheva and Amir Farajian two post-doctoral researcher in the new study, earlier asked the first used to calculate the damage before the ball is in the Back of the hydrogen atom can accommodate the number of ways.

This result is very interesting. 20 years ago, the ball for the first time Buck was found in the Rice University, and now, this new study on the bucky ball again to start Rice University.

Yakobson explained how the small ball is hydrogen storage, he pointed out, "the chemical bonds between carbon atoms, is one of nature's most powerful chemical bonds, which can form chemical bonds present the hardest substance known diamonds. And our research that, in order to bring them inside the fullerene ball carbon carbon - carbon bond deformation or damage, then takes a lot of internal pressure. "

The researchers used a sophisticated computer model can calculate the new storage method for specific details. When the hydrogen atoms were Ru Bake retrobulbar injection, this model can be specified to measure the carbon bucky balls in the strength of chemical bonds between atoms.

The model used to calculate the various dimensions of the fullerene sphere of these carbon structures are particularly desirable, it not only can show Buck the ball can store the hydrogen atoms, but also to simulate the maximum internal storage capacity when the time was a breakthrough Buck how broken the ball.

Porsche 911 GT3 is based on hybrid power







Porsche displayed at the Geneva Motor Show 2010, the hybrid Renner 911 GT3 R. The highlight of his eco-drive: Instead of batteries, a flywheel that stores energy.



Naive reverie or future technology?



By Jan Horn A Porsche high speeds loves living from touring in the red. The boxer engine in a 911 at the limit just feels really comfortable, then screams already well beyond the 7000 mark. Lovely! But this maximum speed is nothing if a GT3 R Hybrid only comes once in full swing. Then the 7000/min a Series-911 shrink to the spinning top-level - the new racer issue makes 40,000 (!) Revolutions. Okay, it's not the six of the Endurance racing car, which goes about it so ludicrously high - but here lies the main module of Porsche's new hybrid approach to the stuff: the flywheel storage.

A flourish of wings animal: the 642 horsepower 911 GT3 R hybrid is designed to show how effectively a hybrid without the batteries.



It is an electric motor-generator unit in oversized, which consists of a magnetized rotor and consists of a plastic plunger. To protect against rupture of the extremely fast circular rotor is still tightly in a plastic sleeve carbon-wrapped. This high-tech gyroscope in the format of a washing machine drum begins with the brakes on the energy produced there later than from electric power again. The maximum "load", which is in this mass momentum, at least six to eight seconds long enough for 162 bhp, which act on two electric motors at the front axle. Power in the GT3 R in conjunction with the hybrid Vierliter boxer engine (480 hp) whopping 642 hp. How Porsche wants mitmischen in May at the 24-hour race at the Nurburgring, downright slow down the competition. Plays in the extra performance just one of several roles. Wheel drive vehicle as it provides extra traction, to run the hybrid racer economical thanks to the energy recovery.

Redoxflow Batteries



Today, electricity is usually stored as energy in storage pumped storage power plants. The power plants have an upper and a lower reservoir. With low demand for electricity, the water with electrical energy, against the force of gravity in the higher-level reservoir is pumped.



The stored water in the upper reservoir can be used to drive the power turbines in order to regain power. The downside: The stores have a relatively low efficiency - so much energy is lost. And they need special geographical conditions - no gap is not current.



Compressed air in the basement of the Earth

One possibility hold electrical energy, providing compressed air storage. This air is compressed and stored in underground caverns, but also their availability is limited.

No question: In order to make electricity from wind and sun to calculate and competitive, a need for new high-performance storage systems. A promising are Redoxflow storage batteries. This enables long-term hold on power for hours or days, and in large quantities. The actual energy storage are liquid electrolytes and stored in tanks.



"Lull prevails or not the sun is the energy stored in a Redoxflow electrode stack, similar to the construction of a fuel cell, converted back into electricity," says Dr. Jens Tübke from the Fraunhofer Institute for Chemical Technology ICT.



Redox Batteries: Smaller and more durable



Compared to conventional lead-acid batteries are redox batteries in these memory sizes smaller, and especially long-lived - they have about ten times longer life. The disadvantage is that they are still in proportion to the power and energy density can be expensive.



Researchers at the ICT will change that: "We have built a prototype developed Redoxflow battery, with which we can test various electrode materials, membranes and electrolytes as flexibly as possible," explained Tübke the approach of the ICT researchers. "In order to compare different redox systems in a test setup. So we can work out the pros and cons of each system clean and test new materials. "



In our mobile world power from the preserve is in high demand. So that we can go in the future not only environmentally friendly car, but also use energy from wind and solar power efficiently, we need new storage systems.

Integrated LDO and DC / DC regulator balance between efficiency and size of the program

Such as: hp pavilion dv2000 battery , hp pavilion dv3000 battery , hp pavilion dv4000 battery , hp pavilion dv6000 battery , hp pavilion dv8000 battery , hp pavilion dv8200 battery , hp pavilion dv8399 battery .

Phone's baseband processor to use the traditional LDO linear regulator power supply, the advantage of a variety of conditions, the output of the noise bias is low, fewer external components, small size, easy to use, disadvantage is low efficiency, but efficiency with chips group to reduce voltage drop. With the functions of cell phones increasing demand for power, designers are using DC / DC regulator to replace the LDO, in order to improve efficiency and maintain battery life. Although the DC / DC regulator provides an efficient alternative, but it is to be the ideal power management devices, need to address the size, noise and switching losses larger issues.

Fairchild Semiconductor Bruno Kranzen manager said that as the battery energy or capacity would be difficult with the rising power requirements, and therefore a smaller form factor to provide more efficient DC / DC conversion is a valid approach, in these systems There is a Switching DC / DC Regulators alternative to linear regulators trend. "

For example, Fairchild's high-speed switching DC / DC regulator FAN5350 switching frequency of 3MHz, designed for handheld applications core processors designed to power. ADI's ADP2102 is a 600mA, 3MHz step-down regulator, and micro-ceramic sensors and capacitors can still be co-existence of up to 93% efficiency.

Best news: hp pavilion dv8140us battery , hp pavilion dv9000 battery , hp pavilion zd7000 battery , hp pavilion zd8000 battery , hp pavilion ze2000 battery .

ADI's director of marketing for portable power products Arcadio Leon, said: "improve the frequency can use smaller capacitors and inductors, thereby reducing the footprint area, but because of increased operating frequency also reduces the overall system efficiency, so the next challenge lies in the operating frequency and found between the shape factor of an ideal balance. "With the increase of switching frequency, DC / DC regulator efficiency benefits will be greatly reduced. 2MHz frequency DC / DC switching loss caused by total loss of 20%, but in the 8MHz frequency, switching losses to rise to 40%.

Clearly, a balance between efficiency, size and cost approach is a combination of switch-mode DC / DC regulator and LDO's new power management IC, they have the former high-efficiency, and the latter's small size and ease of use advantages.

For example, Micrel's recently announced power management IC MIC2800 provides three voltage output: a switch-mode DC / DC regulator output, two LDO outputs. On-chip 2MHz DC / DC regulator provides up to 600mA of current efficiency of 93% or more, just miniature 2.2 F output capacitor and a 2.2 H inductor to stabilize the voltage. The company's power products Ralf Muenster, director of markets and applications, for example, in the digital multimedia broadcasting (DMB) applications, the use of a LDO voltage of the lithium-ion battery is converted to 1.8V (for I / O power supply) and 1.2V (for core power supply), effective rates were 50% and 33%, while the use of integrated MIC2800 in the DC / DC regulator will be lithium-ion battery voltage down to 1.8V, the efficiency of 93%; and then integrated into the MIC2800 in the LDO will be 1.8V is converted to 1.2V, the efficiency of 66%. Other LDO provides a third output voltage, such as the RF voltage of 2.8V rail.

Micrel's director of power products markets and applications Ralf Muenster.

The great HP here: hp pavilion ze4000 battery , hp pavilion ze4200 battery , hp pavilion ze4300 battery , hp pavilion zv5000 battery , hp pavilion zv6000 battery , hp pavilion n3000 battery , hp pavilion n6000 battery , etc.

ON Semiconductor's NCP1526 Dual-Output DC / DC regulators are also integrated 3MHz step-down switching regulator and LDO regulator for the digital multimedia broadcasting (DMB) chip set or a WLAN module in the digital core power supply circuits and RF circuits. This has a number of DC / DC regulator and the LDO output power subsystems will help resolve the clamshell or slider phone board layout, reduce the PMU to flip from the motherboard PCB power alignment, reduce the EMI issue.

ON Semiconductor Product Marketing Manager, Jia-Han also said that power management devices should not only significantly improve full load of work (the current benchmark of 90%), the power conversion efficiency, reduce the time needed to standby (the current benchmark for the 1uA) state of the energy consumption. For the DC / DC regulators, the technology development trends will be used more in the PWM mode and pulse mode (to replace the pure PWM mode) between automatic conversion in order to save power consumption under light load of work.

LED backlight and flash applications, the power demand

Such as: hp pavilion dv4 battery , hp pavilion dv4t battery , hp pavilion dv5 battery , hp pavilion dv5t battery .

Almost all of the portable consumer electronics products are available in color LCD screen to display the users need different types of information and data. LCD's backlight is usually led by a white light to provide. In addition, many mobile phone also has a high resolution can capture still images and video images of the built-in digital cameras, camera performance improvements also had a right for the camera in indoor or dim ambient light conditions, the use of high-power white LED light source demand. These are spawned by a compact, efficient and low-noise way to serve the needs of those LED power supply.

White LED power supply ic usually charge pump and DC / DC regulators, the main difference between the two is the need for an inductor (magnetic components). For the low-load current must be provided in the space-constrained applications, the charge pump is an ideal choice because they use small-outline package, the required external components is very small. Most step-up DC / DC regulator is designed to provide a white LED backlighting for the efficient and designed for constant current drive.

"LED Power Supply IC technology trends is to integrate digital control interface to enhance operational flexibility, such as the LED backlight dimming control." Jia Han said. Semiconductor charge pump NCP5602/5612/5623 support multiple modes of voltage conversion, with a more optimized power conversion, and in lithium-ion battery peak efficiency in the initial stages of the work of up to 90%, the average efficiency of 85%. These devices are integrated into a digital control interface (single or I2C), to achieve LED dimming control. NCP5608 multi-mode charge pump LED drivers, both driving up to four LED in order to support the main screen and sub-screen backlight function, also provides high-current power supply, output current up to 400mA, to drive the 1W of the LED.

Linear Technology's LTC3208 is a non-inductors, high current, the software can be configured to multi-display | Display LED controller capable of driving 17 LED. The device contains a 1A high efficiency, low-noise charge pump may be the main sub-displays for mobile phones, a camera LED display and an LED display of the auxiliary power supply. Because the devices have up to 95% efficiency and an I2C serial interface.

"If you only need a small LED backlight panel can, if the 3.5-inch LCD screen will also need to bias. For small panel applications, LED drivers and can be integrated with the LCD bias, but for large panel applications, integrated LCD bias on the more difficult. "Hsin-Tsung Ho Lung said. TPS65120 converter for portable electronic devices to meet the lcd module all the necessary power requirements. Single-piece four output inductor DC / DC regulator for smart phones, PDA, portable DVD players, digital cameras and other portable applications in the amorphous silicon (a-Si) and low-temperature polysilicon (LTPS) displays provide bias power supply .

High-power LED flash brightness is to obtain high-quality pictures a factor. In some cases, the camera phone is used to drive the LED brightness by the high-power LED step-up DC / DC regulator efficiency limit. This is because the amount of current draw from the battery is limited, so high-efficiency LED would provide a higher power. Arcadio Leon that: At present, the new sensor-based lighting solutions, has a unique dynamic current management capabilities, which makes the system architecture engineers to maximize the supply of LED current, thus increasing the brightness and significantly improve the picture quality.

ADI's ADP1653 is a dual-sensor-based high-power white LED driver, which can provide efficient than a single or low-intensity white led driver a higher camera flash, which makes them available in low-light conditions to achieve higher picture quality. ADP1653 peak efficiency of 92%, lithium-ion battery full voltage range of the typical efficiency is higher than 80%. Than the charge pump solution 40% efficiency, its efficiency is greatly improved.

The device uses a unique current management techniques, even in the battery to work simultaneously to multiple mobile phone functions (such as PA and LED flash) the case of electricity supply can be guaranteed picture quality. In order to reduce battery current overload, LED flash current is transmitted in the cell phone automatically adjust the RF signal, so that system design engineers to increase the LED drive current, do not have to worry about the system due to transient load the battery to shut down prematurely.

Linear Technology's LTC3454 is a camera designed for the high-current applications to optimize the efficiency of lighting, LED current control accuracy and designed products. LTC3454 is a synchronous buck - boost DC / DC regulator designed for the use of single-cell lithium-ion battery up to 1A of current to a single high power LED driver optimized. According to VIN and LED forward voltage, the device can be synchronous buck, synchronous boost and four-switch buck.

Water fuel cell phone

High-tech fuel cell materials - water, fuel cell phone would be this life!

The best hp: HP Battery , HP PB991A , HP PB992A , HP PB994A , HP PB995A , HP PM579A .

Water fuel? Right! Have not you heard wrong, that is, water as fuel. Samsung is currently developing a micro fuel cell can be directly converted to hydrogen using water. This is so what's the do cherish? Alkali Kim Family (periodic table 1A) of metal with the water, stir together, do not have hydrogen can it? that courage you gave me to try sodium dumped into the water.

Certainly, this concept of product should not be used in such a strong activity in metal (perhaps with the oxide, but no sources, said commercial secrets?), But the principle is such a direct, metal in contact with water produces hydrogen gas, hydrogen in fuel batteries, and oxygen in the air role, the release of energy (it should also use a more moderate approach to oxidation of Health is able to), and finally is received 3W of electrical power output, while a certain quantity of water supply, probably enough to the general hand-held unit (currently used in cell phones) to play a ten hours.

At present some of the only drawback is that you must put the storage of hydrogen every few days to replace a small container (if it is used four hours a day, you'll replace one every five days time, this Xiaobian guess may be Excessive accumulation of unreacted oxygen sake), the future is the hope that they can save that person's step is annoyed. For the year 2010 can be formally used in the product to it? Let's wait and see!

In 2020 will become China's third largest wind power, wind power market to accelerate expansion

Internet access prices in wind power increased "rationalization" of the background, the wind power market is accelerating expansion.

Yesterday at the 2007 Shanghai International Wind Energy Conference and Technology and Equipment Exhibition news conference, said Li Junfeng, vice chairman of the Global Wind Energy Council is expected to the end of 2010, China's wind power installed capacity to break down 10 million kilowatts, is expected to reach 12 million, or 1500 kilowatts.

It is reported that as of June 30, 2007, the National completion of wind power installed capacity of 1 million kilowatts, the cumulative installed capacity of 360 million kilowatts. End of this year is expected to add 2.4 million -260 million kilowatts. September of this year, China released "Renewable energy and long-term development planning "of the 2010 installed capacity of 5 million kilowatts of wind power target, you can ahead of three years to complete.

"According to capacity to position two years ago, China's installed capacity of wind power the world's No. 8, No. 6 last year, and this year up to No. 5." Global Wind Energy Council (GWEC) Secretary-General Sawyer (Steve Sawyer) in the above news conference.

He expects wind power market will continue to grow at a rate of 20%. By 2020, the global wind power installed capacity will reach 1000GW, the world's total power generating capacity accounts for 10% to 12%, and thus a corresponding reduction in 1.5 billion tons of carbon dioxide emissions.

Li Junfeng revealed that this year China's wind power installed capacity has been added after the United States (5 million kilowatts) and next year will be closer to the U.S. installed capacity.

At the end of September, Inner Mongolia Autonomous Region to complete one million kilowatts of wind power installed capacity is expected to 2010, the autonomous region of wind power installed capacity is expected to reach 5 million kilowatts.

Energy Development Office of Shanghai Municipal Development and Reform Commission at the meeting also said Fang, Shanghai has built capacity of 2.44 MW wind power. 2010, Shanghai, wind power installed capacity will reach 200,000 MW -30 . Among them, on both sides of the East China Sea Bridge, the construction of 10 electric field thousands of Wahe the upper hand in 2010 Shanghai World Expo will be completed. Shanghai will also be in Nanhui, Fengxian, etc. plans to build offshore wind farm.

Li Junfeng, China's wind power development in long-term goal is that after 10 to 15 years of preparation, about 2020, making wind energy into thermal power, hydroelectric power generation after the third-largest conventional power supply, at least the capacity of 70 million kilowatts, to actively create conditions for realization of 100 million kilowatts, accounting for 10% of power generation capacity by then.

By 2040 or 2050 to achieve 500 million or 10 million kilowatts, in the then installed capacity and electricity generation accounts for more than 20%.
