Experience shows that it takes not very long until the material costs of a new product, which is represented everywhere in the media, until it is broken down into its smallest details. It is not surprising that only a few days after the iPad official unveiling of Apple’s manufacturing and material costs are known.

When it comes to Brian Marshall, his sign of U.S. investment bank analyst Broad Point Amtech, as are the pure material, including a $ 10 surcharge on manufacturing costs, the 16-gigabyte version for about 270 U.S. dollars. Basis of this statement is a “bill of materials” (BOM BOM), but not included in the 20 U.S. dollar as a reserve for warranty costs. With this award would be the variant with 16 gigabytes of memory and Wi-Fi at a production price of 290.50 U.S. dollars.

By far the most expensive component is as expected, the 9.7 “display, which is estimated at about 100 U.S. dollars. Followed by the aluminum enclosure and space for every 25 U.S. dollars. With about U.S. $ 15 from Apple suggests A4 has developed a chip component viertteuerste book.

The situation is different however from the accounts in the UMTS version with 16 gigabytes, for Apple’s approximately 130 U.S. dollars more calls, but only a marginally higher material and production deployment of just over 16 U.S. dollars. Thus, the UMTS device will cost around 306 U.S. dollars, but sold for 629 U.S. dollars and can thus remain about 52 percent of the selling price to cover the development costs, among other iPad for that.

In similar regions also move the 32-gigabyte versions. While the version that has the only WLAN on board, for around 316 U.S. dollars and produced for 599 U.S. dollars are sold, it is the device that can also connect to the mobile Internet, with 332 U.S. dollar production costs a retail price of 729 U.S. dollars. Apple iPad Sales & material prices Product Price Costs iPad 16GB $ 499 $ 290.50 iPad 32GB $ 599 $ 316.00 iPad 16GB + 3G $ 629 $ 306.50 iPad 32GB + 3G $ 729 $ 332.00

Marshall expects for 2010 sales figures for the iPad between 2,2 and 7 million shares, for which the iPad would be a bestseller. Another analyst Ezra Gottheil, volunteered to speak with speculation, which consider that Apple in the future to further price cuts are in the position and could pose a serious competitor to the iPad the netbook market.

U.S. General Accounting Office (GAO) released a report showed the U.S. could begin mass production of fuel cells in 2015, this report also ruled out the possibility of increasing efforts to develop hybrids.

Report contains an analysis, due to policy changes in Congress, the Government’s investment in hybrid R & D has been gradually reduced. From 2003 the federal government has allocated a total 1.2 billion U.S. dollars so far for the development of a hybrid, but one-third of the money has been transferred to other projects.

GAO said the U.S. Department of Energy’s proposed 2015 plan to start mass production of fuel cell vehicles may be extended to achieve, but this technology is more and more and more attention by the Government.

Mini-Notebook for mini Price: Aldi now sells a netbook from Medion for 299 euros. The “Inspiron E1222″ convinces with a long battery life, good facilities and a new processor. But it is not appropriate for all tasks. Computer image has been testing the device -and found a vulnerability.

Business: Sony Battery , vgp-bps2a ,vgp-bps8 ,vgp-bps9/b ,vgp-bps9/s ,VGP-BPS13 , etc.

The magazine “Computer Bild” has tested the new Aldi Netbook: The screen has a standard for this category diagonal of 10.1 inches (25.6 centimeters) and a resolution of 1024×600 pixels. The contrast is very good, but the screen is reflected strongly.

The Medion Akoya E1222 is the first netbook with Intel Atom N450 in the Computer Bild test. The novelty of this processor (codenamed “Pineview”): It also includes the graphics chip and the memory controller -like its big brother, Core i3. The association of several components in a chip package reduces manufacturing costs and a little power consumption.

Speed

Like its predecessor, the N280 Atom processor N450, a rake, and runs at 1.66 GHz core clock frequency. The Inspiron E1222 demonstrated similar performance values, therefore: For office work and for surfing the Internet reaches the speed. Larger tasks like video editing you should expect the mini-notebook will not.

No toy

Like almost all netbooks, the Inspiron is not graphically complex 3D Games: The integrated Intel GMA 3150 graphics unit processor does not have its own memory, calculated on average only 0.8 frames per second.

The 16:9 screen with LED-backlit display measuring approximately 26 inches on the diagonal. Its 1024×600 pixels is sufficient for most programs and web pages. How many current netbooks, the Inspiron also has a screen with a glossy surface.

Thanks to the high-contrast representation of the reflections are not as annoying as in other devices.

Enduring companion

The battery was tested pleasing a lot of perseverance: At work, he held out for almost four and a half hours. On DVD image were even ten minutes more in there -for a 300-euro netbook a class-power.

Volume

In operation, the Akoya produced an audible fan noise (1 sone). This was not loud at compute-intensive tasks.

Lightweight

Despite the large battery the unit weighs only 1150 grams, the keyboard is typical Netbook small, but welcome after a short period of familiarization fluid tap, the somewhat sharp leading edge of housing here, however disturbing. The battery can be taken out if the device gets power from the socket.

Five indicators to measure battery performance

This blog post via: Five indicators to measure battery performance

There five indicators to measure battery performance: Fujitsu Lifebook T5010 Battery , fujitsu fpcbp200 , fujitsu fpcbp200ap , fujitsu fpcbp155 , fujitsu fpcbp155ap , fujitsu lifebook t4220 battery , fujitsu lifebook t4220 tablet pc battery .

Secondary batteries is known as rechargeable batteries or battery,such as Canon bp-522 battery ,measuring the performance mainly depends on secondary battery voltage, capacity, energy, power, cycle life of these five areas.

Voltage including charge and discharge the battery in the theory, the working battery voltage, battery charge voltage and battery termination voltage. theoretical discharge voltage and the theoretical charge voltage is same ,and they are equal to the battery open circuit voltage,like the battery for Canon bp-711 .

The battery voltage is the actual battery discharge voltage ,it is relevant with the battery discharge method, using temperature, charge and discharge times and others(it also includes whether it is famous battery,such as Samsung sb-l110 battery or not ) .The battery charging voltage is greater than open-circuit voltage, the greater charge current is ,the voltage higher , the greater the battery heat ,the temperature of the battery during charging higher.

Termination of the battery voltage is that the the voltage of battery is not appropriate to continue to discharge down to the minimum operating voltage in the discharge process,.

Battery capacity refers to a certain discharge conditions, you can get electricity from the battery, that battery can release energy. Battery capacity is divided into theoretical capacity, practical capacity. The battery’s theoretical capacity is calculated in accordance with the electrochemical reaction from the capacity. Actual capacity refers to a certain discharge conditions, the battery can release the actual amount of power,for one thing,the Canon bp-911 battery.

The battery capacity is defined as more than a certain discharge conditions,obtained battery power from the unit mass (volume) , that is,the battery can release energy. Such as: fujitsu lifebook e8310 battery , fujitsu lifebook e8210 battery , fujitsu fpcbp136 , fujitsu fpcbp136ap , and fujitsu lifebook n6210 battery , fujitsu lifebook n6220 battery , fujitsu lifebook e8310 battery .

The energy of the battery is the output of electricity can do work outside in certain discharging conditions , As the active substance can not be fully exploited, and the battery voltage is always less than the electromotive force, take the Jvc bn-v408 battery,so the actual energy of the battery is always less than the theoretical energy.

The battery specific energy (energy density) is the output energy of unit mass (volume) batteries , namely, the volume ratio energyor the mass ratio energy. the actual output energy is the energy of the battery ratio battery quality (weight) or volume .

The battery power is the battery the battery output battery power per unit time in a certain discharge conditions, unit is for the W or kW. Battery power is the power unit mass (volume) cand output ,the unit is for the W / kg or W / l.

Common fuel cells

This article via: Common fuel cells

Here are five kinds of fuel cells :

Proton exchange membrane fuel cell (PEMFC), the good ones: ibm 40Y6795 , ibm 40Y6797 , ibm 40Y6799 , lenovo thinkpad t60 Battery , ibm 92P1101 , ibm 92P1102 , etc.

The electrolyte of Proton exchange membrane fuel cell(like the inspiron 1520 battery) is a thin polymer membrane in the proton exchange membrane fuel cell,such as poly [perfluoro sulfonyl] acid (poly [perfluorosulphonic] acid), and protons can penetrate, but not conductive NafionTM , while the electrode is composed of basically carbon. Hydrogen go into the fuel cell to reach the anode,and cracked into hydrogen ions (protons) and electrons. Hydrogen ions go into the cathode through the electrolyte penetration, while the electrons flow through an external network to provide electricity. At the same time, to form the air of oxygen for supplying the cathode, and combine with electrons and hydrogen ions to form water.

Alkaline fuel cell (AFC): dell vostro 1400 battery , dell vostro a840 battery , dell vostro a860 battery .

Alkaline electrolyte fuel cell use a potassium hydroxide aqueous solution or a stable matrix as electrolyte ,such as Dell inspiron 6000 battery, and the electrochemical reactions move from the cathode to the anode reacts with the hydrogen in water and electronics ,which is slightly different. These electrons first provide energy for the external circuit , then returning to the cathode to react with oxygen and water to produce more hydroxyl ions.

Phosphoric acid fuel cell (PAFC): dell xps m140 battery , dell xps m1210 battery , dell xps m1330 battery , dell xps m1530 battery , dell xps m1710 battery , dell xps m1730 battery.

Such cells use liquid phosphoric acid as the electrolyte, the operating temperature is slightly higher than the proton exchange membrane fuel cells and alkaline fuel cell operating temperature, it is 150 ~ 200 ℃ or so, but still rely on the platinum electrode catalyst to speed up the reaction. The anode and cathode reactions and proton exchange membrane fuel cell is same, but because of its higher operating temperature, so its reaction is faster than proton exchange membrane fuel cell cathode speed on the cathode ,take the Dell inspiron 6400 battery for example .

Molten carbonate fuel cell (MCFC): dell latitude X300 battery , dell vostro 1000 battery.

Molten carbonate fuel cell (for one thing ,the Dell latitude d830 battery )uses a molten lithium-potassium carbonate or lithium sodium carbonate as the electrolyte. When the temperature is heated to 650 ℃, this salt will melt, producing carbonate ions, flow from the cathode to the anode , and combine with hydrogen produce water, carbon dioxide and electronics. Electronics and then return to the cathode through an external circuit, generating in this process.

Solid oxide fuel cell (SOFC): dell latitude x1 battery , dell latitude x200 battery , dell inspiron 6000 battery.

Solid oxide fuel cell operating temperature is even higher than the molten carbonate fuel cell temperature, used as solid ceramic electrolyte, such as yttria stabilized zirconia and other solid ceramic electrolyte, instead of using the liquid electrolyte. Its operating temperature is located between 800 ~ 1000 ℃. In such a fuel cell for Dell inspiron e1505 battery , when the oxygen ion moving from the cathode to the anode, so that oxidation of fuel gas (mainly hydrogen and carbon monoxide mixture)generate energy. Anode return to the cathode to reduce the access of oxygen through the external circuit, thus completing the cycle.
