History of Windows Mobile Operating Systems

Windows Mobile has seen many faces throughout the past ten years. Despite all of Microsoft's changes to their mobile devices, it has been losing its share of the smartphone market year after year with 2009 showing a 20% loss. Microsoft's Window Mobile is now the fifth most popular smartphone operating system. It falls behind Symbian, BlackBerry OS, Android and iPhone. In the United States, it is the third most popular smartphone operating system. Despite this, Microsoft is releasing the Windows Phone 7, after much revamping, later this year.

The history of Windows Mobile goes like this. First of all, there are three versions of Windows Mobile for various devices - they include:
Windows Mobile Professional runs on (smartphones) with touch screens, Windows Mobile Standard runs on phones with regular screens and Windows Mobile Classic which runs on 'Windows Mobile Classic devices' (Pocket PCs).

Microsoft first introduced the Pocket PC before releasing Windows Mobile. The Pocket PC 2000 was a personal digital assistant or PDA. This PDA differed from companies such as Palm in that it contained Windows software like Office, Windows Media Player and other Microsoft products. The Pocket PC 2002 was released in 2002 and included Windows Mobile and the PDA capacity.

The Pocket PC 2002 was also called Merlin and it was powered by Windows CE 3.0. Features included those of the 2000 plus spell checker, word count, MSN messenger and more.

In 2003, Windows Mobile 2003 was released and called Ozone. It came in four editions - "Windows Mobile 2003 for Pocket PC Premium Edition", "Windows Mobile 2003 for Pocket PC Professional Edition", "Windows Mobile 2003 for Smartphone" and "Windows Mobile 2003 for Pocket PC Phone Edition". New features included Bluetooth, picture applications, support for add-on keyboards, and a host of other items.

The Windows Mobile 2003 SE was released in 2004 and allowed users to backup and restore their device through ActiveSync.

Windows 5.0, named Magneto was released in 2005. It used the .NET Compact Framework 1.0 SP3 — an environment for programs based on .NET. It also had push functionality, photo caller ID, GPS and the QWERTY keyboard.

In 2007 came the Windows Mobile 6 "Crossbow". It came in three different versions: "Windows Mobile 6 Standard" for Smartphones (phones without touchscreens), "Windows Mobile 6 Professional" for Pocket PCs with phone functionality, and "Windows Mobile 6 Classic" for Pocket PCs without cellular radios. Windows Mobile 6 was powered by Windows CE 5.0 (version 5.2) and is strongly linked to Windows Live and Exchange 2007 products. Windows Mobile 6 was meant to be similar in design to the then newly released Windows Vista. Windows Mobile 6 included Office Mobile, VoIP calling, improved Internet sharing, HTML email and Microsoft Office OneNote.

Windows Mobile 6.1 followed in 2008 with minor upgrades from 6. There were minor performance enhancements such as a redesigned Home screen with horizontal tiles that expand on clicking, threaded SMS, full page zooming, Domain Enroll, improved bandwidth in push email and improved battery life.

Windows 6.5 and then 7 followed. Windows Mobile 6.5 was described by Microsoft as not being the full release they wanted. The Windows Mobile 7, will be replaced by the Windows Phone 7, which arrives soon this year, 2010. WP7 is codenamed Photon. While the WP7 was to be released in 2009, many ideas were scrapped and progress was delayed as a new platform was designed. WP7 will include a new operating system and integration with Xbox Live and Zune services. To own a WP7, once it is released, will be relatively easy as the company has so many carrier partnerships, including all the large providers such as Verizon, Sprint, AT&T and many more. The company is hoping to have the handsets available before the holidays.

Free iPad Tester Program You can Get a Free iPad Too!

Do you know that you can get an Apple iPad for free ?
You know how when a new technology enters the market that you really want, but just do not have the extra money? it can be frustrating. This is the case for many of us with the new Apple iPad. If you do not have $ 500 to spend on this wonderful new piece of technology today, you'll still be able to get a free Apple iPad if you follow my advice.

Although it might seem a kind of scam, but it's true that some research companies really need testers for their products. Ultimately, this is known as marketing research and companies in desperate need of decent people to give their opinion. Sometimes, this means that you can help by giving an honest examination of how the product works.

These companies will not only pay you to test their products but actually give you the product itself. However, you should be very careful because some of these sites are not legitimate. If they ask you to give them a credit card to receive a product for testing, stay away as fast as possible. A legitimate offer will never ask for money or and does not require you to buy anything to get the gift. Always use caution when navigating for a genuine free Apple iPad event.

Typically, companies provide a number of free items to be tested by the private members of the public. They are lucky people who manage to test them without any cost to them. This is where you come in. Just find a legitimate website that allows you to register to test their products. Make sure you also read their Terms of Use before signing anything.

Absolutely, you can get a free Apple iPad, and many other products, but the important thing is to ensure that the site that offers the product is a legitimate website, and you may be lucky to get one of yours.

What's the sniper's aim?!

Wills & grant 1858 to 2010 Order online £20.00Read more: Under Creative Co

When we mention the idiom "sniper" most of us imagine the sniper games, like the celebrated Counter Strike, or some motion picture with an isolated ranger who is enigmatic, very focused and precise, works alone with his guns that point with red light, like the guy in the motion picture Shooter.

According to the definition "sniper" is an eminently trained soldier who specializes in bringing down targets with modified rifles from especially long distances. These soldiers are also well trained when it comes about being secret, about cover-up, infiltration, and the observation techniques. And even if most of the people assume that their job is to "pull the trigger", as a matter of fact, the true snipers work for the military and law enforcement agencies. They are far more concerned with the number of the lives they are saving than with the ones they are taking.

Sniper's principal mission is investigation. These soldiers are proficient of stealth and they are perfectly proper to sneak behind enemy lines. They appoint command with information about the enemy's size, its power and its location, and center their attention to the key figures from the enemy lines - officers, pilots, armour drivers, technicians, and communications operators. Snipers shoot without warning and that's how they break both the enemy's will.

If there's no specific goal, a sniper looks for, so called, targets of opportunity. They attend the activities of the enemies and wait calmly some of the soldiers to rest or to be not prepared to defend or hit back - a pilot flight that checks his helicopter, officer taking a break to smoke a cigarette, an armed guard on patrol…

Sniper's targets are not just people. Many tames they have to damage material targets like transmitters, generators, radios, fuel and water supplies, etc.

Snipers are very often used in support roles, based on taking a place that has a clear view of the battlefield, maybe setting up on a roof, and assistance the assault force by taking out enemy forces that are jeopardizing the advancing platoon or help ground forces to care for their position.

Military strategists refer to the snipers as force multipliers that means an individual or small team that uses special methods. With their methods they are capable do the damage of a much larger force and force multiplication, without a directly engage with the enemy.

These soldiers move very carefully, under the cover of brush or night, taking with them very small baggage. A number of times need to stay entirely still for hours or days, waiting for the right bit to take the shot, but at the same time to avoid uncovering. It may seem surprising, but they never travel alone.

According to the definition "sniper" is an extremely well trained soldier who specializes in executing targets with modified rifles from strangely long distances.

Sniper's first mission is reconnoitring. These soldiers are proficient of stealth and they are perfectly fitting to sneak behind enemy lines.

Usually they need to stay quite still for hours or days, waiting for the right minute to take the shot, but to avoid unmasking at the same time. It may seem surprising, but they do not travel alone.

How to choosing MP3

is currently the market fully to all divers. Many people would like to use the MP3 to listen to resolve lonely. But looking at it to see a fully sold out to the store. I recommend buying MP3 same way.

MP3 recording is divided into 2 types.

1. Flash Memory Stick format other. Most sizes. 32/64/128/256/512MB and 1 GB to 2 GB is better resistant to shock level one

2. The Hard Disk can be subtle. Compared with the computer's hard drive. Users must be careful to carry enough. The case has produced much cushioning as various iPod models, but the advantage of high capacity 30GB / 60GB can hold thousands of songs to music.From the analysis of our work. What we use.

MP3 is usually qualified as the fourth major.

1. Radio
2. Recorded three
3. Listen to Radio
4. Recorded data (or use a Storage Drive Handy Drive).
Here you have to think that you bought what used mainly Because by then most MP3 is not very different. The worry is more about the warranty.

Listening to music.

Music that If you have a regular CD. You can use Windows Media Player convert files to MP3 or WMA files already, do not worry that will not listen.

Recording, have two types of recording with built-in microphone. May have to consider whether you want good quality sound how Try recording the shop before buying more. Another option is to record from

Line-in that is able to record sound from various sources to it. Such as recording from a CD player, TV or other audio source. For clarity of sound Or the external microphone will enable audio recording quality and clearer.

Listening to radio: I must say that before. To listen to radio from MP3. Most wired headphones with the antenna signal. Therefore, the hearing may not be obvious in some range. Listen now or car. Is not equivalent to listening to radio in the car, but for some models can record radio.

Recording information: MP3 can save data like a Handy Drive general, but asked to be careful that the memory may be used to contain music, if we use the 256MB we keep the music tattoo 128MB a 128MB left can save others.

Connection, have two types.

Cable may not be easy because the USB cable to carry the field.USB Plug is connected to your computer immediately.Connection speed: USB1.1 / USB2.0.
Current is a USB2.0 Hi-Speed and the speed of data transfer very fast.

Screen.
The current screen is divided into two types.
The LCD / OLED / Backlight a second color or black and white or 7 color OLED (usually battery AAA).
Is an LCD TFT color screen for Dict (because of color need more power. Battery is a Li-Polymer).

Weight:.
Normally the weight of the player is not so much what Still have to use a Li-polymer battery is lighter and much more.

Choose what best.

Do not ask that the chosen model where brands do better That's it, you learn from the best websites. Ask friends who've used. Better than to believe that employees try to play more important Listen Listen to music Use fewer players see Or visit the website reviews and various computer magazines also available. Good luck to the owners of MP3 please.

Innovation, batteries, and the new energy revolution

For almost a week now the IBD article Volt fraud at Government Motors has been bouncing around my head.
For years I've advocated for the purchase of hybrid cars while longing for a big move to plug-in hybrids, even though most hybrid purchases are not cost-effective for most hybrid buyers. Nonetheless, eating a local, organic diet might not be cost-effective compared to a McDonald's value meal, but it's still far healthier, and a commitment to ending foreign oil dependence is just as healthy. Acer laptop batteries.
Yet, after a decade on the market, hybrids can't even achieve 3 percent market share, despite the government pumping billions of tax payer dollars into these vehicles. That reality, as unfortunate as it might be, is reality.
Now come electric cars and billions more already committed, with the possibility of tens of billions more – exactly what I advocated for years ago - to turn even less cost-effective and unwanted plug-in cars into real world vehicles for the 5 percent of the population that is absolutely committed to going green and/or fighting foreign oil dependence.
Consequently, in some ways hybrids, plug-ins and the Volt do feel like a fraud.
But they are not.
Without any question, the Volt is far too much about marketing rather than GM profits. Still, the Nissan Leaf and the Toyota Prius are more about marketing than sales. All, however, have been worth the investment. Whether they are worth tax credits or not is another question, but that's not the focus of this post. sony laptop battery.
Certainly, those following this blog know I've been terribly critical of the Chevy Volt. Nevertheless, I've never thought of the Volt as a fraud, never. Sure, I've been very disappointed that GM has, much like Nissan, used the Volt and plug-ins as an excuse not to take greater action on hybrid cars – the battery powered cars with the greatest interim potential according to the latest science – but the more critical issue is R&D into electrification and the innovations such a focus create.
While the potential of hybrid and electric cars is still very much in question, and there is a chance that lithium-powered vehicles will be viewed as the biggest hoax ever in the auto industry, lithium-powered vehicles could, nonetheless, still revolutionize the auto industry.
And that's the rub. Anything is still possible.
The oil-driven economy, however, is nearing its end. Yes, that end could be fifty years away, even a hundred years. Or, it could be just a decade away from its peak. Regardless, history has demonstrated that revolutionary technological breakthroughs are inevitable when it comes to energy, and such revolutions are occurring ever faster. Considering the fact that world could need 40 percent more energy by 2030 – around the same time the population of the world DOUBLES – energy revolution is inevitable. dell battery replacement.
It might not be the battery, or at least not the lithium-battery, that revolutionizes the auto industry. Instead, something like the Volt might just be the spark that ignites the real revolutionary breakthrough. Regardless, change is coming and that change will be led by innovation – the kind of innovation that hybrids and plug-ins like the Volt are breeding.
Consequently, if the Volt is a fraud, it is far less fraudulent than assuming that America can secure its future upon foreign oil dependence for several more decades without revolutionary technological breakthroughs. And the only way such breakthroughs will be achieved is by developing vehicles like the Volt.

There are many different kind of oscilloscope. In this article I am going to explain about digital oscilloscope. Digital oscilloscope is different from analog oscilloscope. In digital oscilloscope the waveform is displayed and digitalized. The voltages values are saved in time scale in the memory waves. Basically, digital oscilloscope only repeats the process until it is finished. Some Digital Oscilloscope (DSO) selects the number of the sample stored in memory per acquisition.

DSO performs acquisition in each triggering event. The DSO regularly gets, measures, and also stores the input signal. Then, it delivers the signal through the memory in a process of: first saved - first issued while waiting for a triggering event. Once the oscilloscope is able to identify the triggering event, it takes a snapshot of the waves and then it delivers the information to the monitor. The DSO has two ways in capturing the wave. The first way is by doing a real time sampling and the second is by performing single shot technique. The two techniques results in the footage captured of a triggering event.

A digital oscilloscope must be able to capture the input signal frequency when it performs single shot waveform. Usually a DSO has two kinds of bandwidths. The bandwidths are real time bandwidth and analog bandwidth. Analog bandwidth shows the maximum frequency that can perform accurate snapshot within a triggering event. By using an alternative method of equivalent time sampling, a DSO can accurately capture the signals to the corner of the ribbon. Oscilloscope then receives a lot of triggering events that construct the waveform.

Most of the DSO samples the maximum rate without referencing to a time base. In certain low speed sweeping, the DSO receives a lot more shots than its bandwidth. We can use DSO in several acquisitions mode. The DSO might delete the rest of the shots or use them for the next signals analysis.

Lithium iron phosphate battery

From Wikipedia, the free encyclopedia

Jump to: navigation,

Lithium iron phosphate battery
specific energy	90–110 Wh/kg (320–400 J/g)
energy density	220 Wh/L (790 kJ/L)
specific power	>3 W/g
Energy/consumer-price	US$0.40–2.00/Wh (US$0.11–0.56/kJ)
Time durability	>10 years
Cycle durability	2,000 cycles
Nominal cell voltage	3.3 V

The lithium iron phosphate (LiFePO₄) battery, also called LFP battery, is a type of rechargeable battery, specifically a lithium ion battery, which uses LiFePO₄ as a cathode material.

[hide]

History

LiFePO₄ was discovered by John Goodenough's research group at the University of Texas in 1996,^[1]^[2] as a cathode material for rechargeable lithium batteries. Because of its low cost, non-toxicity, the high abundance of iron, its excellent thermal stability, safety characteristics, good electrochemical performance, and high specific capacity (170 mA·h/g, or 610 C/g) it gained some market acceptance.^[3]^[4]
The key barrier to commercialization was its intrinsically low electrical conductivity. This problem, however, was then overcome partly by reducing the particle size and effectively coating the LiFePO₄ particles with conductive materials such as carbon, and partly by employing the doping^[3] approaches developed by Yet-Ming Chiang and his coworkers at MIT using cations of materials such as aluminum, niobium, and zirconium. It was later shown that most of the conductivity improvement was due to the presence of nanoscopic carbon originating from organic precursors.^[5] Products using the carbonized and doped nanophosphate materials developed by Chiang are now in high volume mass production by A123Systems and other companies,^{[citation needed]} and are used in industrial products by major corporations including Black and Decker's DeWalt brand, General Motors' Chevrolet Volt, Daimler, Cessna and BAE Systems.
Most lithium-ion batteries (Li-ion) used in consumer electronics products are lithium cobalt oxide batteries (LiCoO₂). Other varieties of lithium-ion batteries include lithium-manganese oxide (LiMn₂O₄) and lithium-nickel oxide (LiNiO₂). The batteries are named after the material used for their cathodes; the anodes are generally made of carbon and a wide variety of electrolytes are used.

Advantages and disadvantages

The LiFePO₄ battery uses a lithium-ion-derived chemistry and shares many of its advantages and disadvantages with other lithium ion battery chemistries. The key advantage for LiFePO₄ when compared with LiCoO₂ is higher current or peak-power rating.^[6]
LFP batteries have some drawbacks:

The specific energy (energy/volume) of a new LFP battery is somewhat lower than that of a new LiCoO₂ battery. Battery manufacturers across the world are currently working to find ways to maximize the energy storage performance and reduce size & weight.^[7]
Many brands of LFP's have a low discharge rate compared with lead-acid or LiCoO₂. Since discharge rate is a percentage of battery capacity this can be overcome by using a larger battery (more ampère-hours). However, A123Systems claims 100C pulse discharge rate.^[8]

While LiFePO₄ cells have lower voltage and energy density than LiCoO₂ Li-ion cells, this disadvantage is offset over time by the slower rate of capacity loss (aka greater calendar-life) of LiFePO₄ when compared with other lithium-ion battery chemistries (such as LiCoO₂ cobalt or LiMn₂O₄ manganese spinel based lithium-ion polymer batteries or lithium-ion batteries).^[9]^[10] For example:

After one year on the shelf, a LiFePO₄ cell typically has approximately the same energy density as a LiCoO₂ Li-ion cell.
Beyond one year on the shelf, a LiFePO₄ cell is likely to have higher energy density than a LiCoO₂ Li-ion cell due to the differences in their respective calendar-lives.

Specifications

Cell voltage = min. discharge voltage = 2.8 V. Working voltage = 3.0 V – 3.3 V. Max. charge voltage = 3.6 V.
Volumetric energy density = 220 Wh/dm³ (790 kJ/dm³)
Gravimetric energy density = >90 Wh/kg^[11] (>320 J/g)
100% DOD cycle life (number of cycles to 80% of original capacity) = 2,000–7,000 ^[12]
Cathode composition (weight)
- 90% C-LiFePO4, grade Phos-Dev-12
- 5% Carbon EBN-10-10 (superior graphite)
- 5% PVDF
Cell Configuration
- Carbon-coated aluminum current collector 15
- 1.54 cm² cathode
- Electrolyte: EC-DMC 1-1 LiClO₄ 1M
- Anode: Metallic lithium
Experimental conditions: ** Note the following is for Cobalt Cathode LiIon cells - should be changed for LiFePO
- Room temperature
- Voltage limits: 2.5 – 4.2 V
- Charge: C/4 up to 4.2 V, then potentiostatic at 4.2 V until I < C/24

] Safety

LiFePO₄ is an intrinsically safer cathode material than LiCoO₂ and manganese spinel. The Fe-P-O bond is stronger than the Co-O bond, so that when abused, (short-circuited, overheated, etc.) the oxygen atoms are much harder to remove. This stabilization of the redox energies also helps fast ion migration. Only under extreme heating (generally over 800 °C) does breakdown occur and this bond stability greatly reduces the risk of thermal runaway when compared with LiCoO₂.^{[citation needed]}
As lithium migrates out of the cathode in a LiCoO₂ cell, the CoO₂ undergoes non-linear expansion that affects the structural integrity of the cell. The fully lithiated and unlithiated states of LiFePO₄ are structurally similar which means that LiFePO₄ cells are more structurally stable than LiCoO₂ cells.^{[citation needed]}
No lithium remains in the cathode of a fully charged LiFePO₄ cell—in a LiCoO₂ cell, approximately 50% remains in the cathode. LiFePO₄ is highly resilient during oxygen loss, which typically results in an exothermic reaction in other lithium cells.^[4]

Usage

LFP batteries were featured on the November 5, 2008 episode of Prototype This!. They were used as the power source for a hexapod (walking) vehicle. Lithium Technology Corp. announced in May 2007, that they had developed a new Lithium Iron Phosphate battery with cells large enough for use in hybrid cars, claiming they are "the largest cells of their kind in the world."^[13]. While they may be large enough for such uses, there remain limitations to the use of this particular Lithium battery technology which may make their use contraindicated. See Advantage and Disadvantages above for details.
This battery is used in the electric cars made by Aptera^[14] and QUICC.^[15]
This type of battery technology is used on the One Laptop per Child (OLPC) project.^[16]
Killacycle, the worlds fastest electric motorcycle, uses lithium iron phosphate batteries.
Roehr_Motorcycle_Company, uses a 5.8 kW·h capacity LFP battery pack to power its supersport electric motorcycle.
Segway Personal Transporters advanced from a 10 mile range to a 24 mile range with Valence Lithium Phosphate technology.^{[citation needed]}
OLPC batteries are manufactured by BYD Company of Shenzhen, China, the world's largest producer of Li-ion batteries. BYD, also a car manufacturer, plans to use its Lithium Iron Phosphate batteries to power its PHEV, the F3DM and F6DM (Dual Mode), which will be the first commercial dual-mode electric car in the world. It plans to mass produce the cars in 2009.^[17]
LFP batteries are gaining popularity now in the world of hobby-grade R/C, due to the benefits over the ever-popular LiPo batteries. They can be recharged much faster and for more cycles, are not prone to catching fire or exploding while recharging, and are more robust than the LiPo type.
LFP batteries are used by electric vehicles manufacturer Smith Electric Vehicles to power its products.
Used by Minneapolis Electric Bike.
Some electronic cigarette modifications also use these types of batteries.
