There are strong opinions and preferences between battery chemistries

June 11 [Tue], 2013, 15:29
New hydride alloys discovered in the 1980s offered better stability and the development of NiMH advanced in earnest. Today, NiMH provides 40 percent higher specific energy than a standard NiCd, but the decisive advantage P775 compatible is the absence of toxic metals.

The advancements of NiMH are impressive. Since 1991, the specific energy has doubled and the life span extended. The hype of lithium-ion may have dampened the enthusiasm for NiMH a bit but not to the point to turn HEV makers away from this proven technology. Batteries for the electric powertrain in vehicles must meet some of the most demanding challenges, and NiMH has two major advantages over Li-ion here. These are price and safety. Makers of hybrid vehicles claim that NiMH costs one-third of an equivalent Li-ion system, and the relaxation on safety provisions contribute in part to this price reduction.

Nickel-metal-hydride is not without drawbacks. For one, it has a lower specific energy than Li-ion, and this is especially true with NiMH for the electric powertrain. The reader should be reminded that NiMH and Li-ion with high energy densities are reserved for consumer products; they would not be robust enough for the hybrid and electric vehicles. NiMH and Li-ion for the electric powertrain have roughly one-third less capacity than consumer batteries.

NiMH also has high self-discharge and loses about 20 percent of its capacity within the first 24 hours, and 10 percent per month thereafter. Modifying the hydride materials lowers the self-discharge and reduces corrosion of the alloy, but this decreases the specific energy. Batteries for the electric powertrain P775D compatible make use of this modification to achieve the needed robustness and life span.

There are strong opinions and preferences between battery chemistries, and some experts say that NiMH will serve as an interim solution to the more promising lithium systems. There are many hurdles surrounding Li-ion also and these are cost and safety. Li-ion cells are not offered to the public in AA, AAA and other popular sizes in part because of safety. Even if they were made available, Li-ion has a higher voltage compared to nickel-based batteries.

AGM batteries are sensitive to overcharging

June 11 [Tue], 2013, 15:20
AGM technology was developed in 1985 for military aircraft to reduce weight, increase power handling and improve reliability. The acid is absorbed by a very fine fiberglass mat, making the battery spill-proof. This enables P770 compatibleshipment without hazardous material restrictions. The plates can be made flat to resemble a standard flooded lead acid pack in a rectangular case; they can also be wound into a cylindrical cell.

AGM has very low internal resistance, is capable to deliver high currents on demand and offers a relatively long service life, even when deep-cycled. AGM is maintenance free, provides good electrical reliability and is lighter than the flooded lead acid type. It stands up well to low temperatures and has a low self-discharge. The leading advantages are a charge that is up to five times faster than the flooded version, and the ability to deep cycle. AGM offers a depth-of-discharge of 80 percent; the flooded, on the other hand, is specified at 50 percent DoD to attain the same cycle life. The negatives are slightly lower specific energy and higher manufacturing costs that the flooded. AGM has a sweet spot in midsize packs from 30 to 100Ah and is less suitable for large UPS system.

AGM batteries are commonly built to size and are found in high-end vehicles to run power-hungry accessories such as heated seats, steering wheels, mirrors and windshields. NASCAR and other auto racing leagues choose AGM products because they are vibration resistant. AGM is the preferred battery for upscale motorcycles. Being sealed, AGM reduces acid spilling in an accident, lowers the weight for the same performance and allows installation at odd angles. Because of good performance at cold temperatures, AGM batteries are also used for marine, motor home and robotic applications.

Ever since Cadillac introduced the electric starter motor in 1912, lead acid became the natural choice to crank the engine. The classic flooded type is, however, not robust enough for the start-stop function and most batteries in a micro-hybrid car are AGM. Repeated cycling of a regular flooded type causes a sharp capacity fade after two years of use. See Heat, Loading and Battery Life.

As with all gelled and sealed units, AGM batteries are sensitive to overcharging. These batteries can be charged to 2.40V/cell (and higher) without problem; however, the float charge should be reduced to between 2.25 and 2.30V/cell (summer temperatures may require lower voltages). Automotive charging systems for flooded lead acid often have a fixed float voltage setting of 14.40V (2.40V/cell), and a direct replacement with a sealed unit could spell trouble by exposing the battery to undue P770D compatibleovercharge on a long drive. See Charging Lead Acid.

AGM and other sealed batteries do not like heat and should be installed away from the engine compartment. Manufacturers recommend halting charge if the battery core reaches 49°C (120°F). While regular lead acid batteries need a topping charge every six months to prevent the buildup of sulfation, AGM batteries are less prone to this and can sit in storage for longer before a charge becomes necessary. Table 1 spells out the advantages and limitations of AGM.

Social media sites only contributed 2.85% of the online shopping traffic

August 13 [Mon], 2012, 15:01
According to the latest cnet.com reports, the latest research shows that in the area of online shopping, search and e-mail is still more than social media.

According to a latest report released today by the marketing company Monetate, although in the past year, the contribution of social media for online shopping site traffic growth in the year 77%, almost none of the actual user, through it to purchase good.

The company's research shows that in the second quarter of 2012, in terms of actual sales results, recommended shopping sites for search engines and e-mail is still more than social media sites to much more effective.

In the second quarter, the social media sites only contributed 2.85% of the online shopping traffic, but from early 2011 to early 2012, this figure has increased by 77%.

In all the social networking site, Facebook recommended shopping sites contributed the most traffic. Facebook enables users to browse the merchandise in the other sites did not encounter any difficulties, but after browsing this page, almost half of the users will not access other pages. Less than five thousandths of users are browsing this page will actually buy the merchandise page.

In comparison, Google's conversion rate (the flow into the measure of actual sales) reached 2.44%, while the e-mail conversion rate up to 4.25%.

As the Monetate chief marketing officer, Kurt Hai Neiman (Kurt Heinemann) believe that social media compared to lower the overall value of these companies should be aware of this. When consumers want to buy something, they still tend to go directly search this product.

But he also believes that this does not mean that these companies should not be using social media. For these companies in terms of social media to create an image of almost any money to spend.

Hai Neiman said: "This simply means that we should be very cautious exaggerated propaganda, social media, a lower conversion rate compared with traditional methods should be taken into account."

This report also provides a variety of devices, operating systems and browser-specific figures of the conversion rate.

Some of the anecdotes in this report:

Hai Neiman said that the use of mobile devices - such as smart phones and tablet PCs - to navigate the ratio rose from 5.89% to 11.6% of the online shopping site, and this upward trend will continue.

The smart phone is more often used to browse and watch a specific items, but do not generally use their shopping. Higher conversion rate of tablet PCs and desktop computers. The Hai Neiman said this is because users feel more at ease, it's because of the smart phones can not provide all the necessary information when shopping smart phone shopping is not.

Apple iPad to higher rates of access to the site, but its conversion rate is almost the same as the Kindle Fire and Google Android Tablet.

IPhone market share is still growing, Andrews smartphone users the conversion rate is still higher than the conversion rate of iPhone users.

In the browser market, IE is still the first, but its market share continues to decrease, from 49.37 percent share in the past year to 37.5%. In comparison, Chrome's market share at the same time increased from 10.89% to 17.15%.


2013 Ultrabook portable platform is incorporate wireless charging between notebooks and mobile devices

August 13 [Mon], 2012, 14:58
Chip giant Intel is working on a new technology for its 2013 Ultrabook portable platform that is said to incorporate wireless charging between notebooks and mobile devices, per a new report out of Asia based on sources from the upstream supply chain.

As MacBooks use Intel’s chips, Apple could adopt this upcoming technology from Intel to enable wireless charging between future MacBooks and your iPhone, iPad or iPod touch…

Asian trade publication DigiTimes.com notes that Japan’s carrier NTT Docomo and consumer electronics giant Sharp both previously launched smartphones with wireless charging functions that meet the Wireless Power Consortium’s (WPS) Qi standard, though high prices and reliability issues prevent their solution from being mainstreamed.

Samsung also wanted to debut a resonance wireless smartphone charger in June, but had to delay the project into 2013 as performance still needs some improvements.

Cupertino’s been researching various aspects of wireless charging techniques, such as inductive charging. Apple typically registers patents for a bunch of different things, but many of them never see the light of day so those patent filings only mean that Apple is, or was, thinking about wireless changing.

Coincidentally or not, The Wall Street Journal reported a year ago that Apple was experimenting with “a new way of charging the phone”.

Do you think iPad Charger is a useful feature or just a gimmick?

Any successor to have all the advantages of Steve Jobs

June 14 [Thu], 2012, 17:02
June 14 news, the U.S. hedge fund Ironfire Capital founder Eric Jackson (Eric Jackson) at the Forbes website on Wednesday published an article, said Tim Cook, Apple CEO Tim Cook is a very special business leaders, he did not pursue those who simply can not achieve, such as people are looking for "Jobs", on the contrary, his pursuit of perfection camera battery grips.

The following is a summary of the article:

I is Apple's concern, and often asked "Do you think the new CEO Tim Cook Tim Cook, the performance of such a problem.

A few days ago someone asked me that question, I told her: his performance was perfect , incredible. Cook and his management team under the leadership of Apple is to accelerate progress.

She responded: "Do you think Apple's stock is still a safe investment? I should buy? Will continue to rise? After all, Cook is not Steve Jobs, right?"

Admittedly, I do not know that Cook's performance in the future will be to what extent well. He did not Steve Jobs, but to understand that no one else will Steve Jobs, and the future.

Cook, not Steve Jobs, but he is the best cook. In my opinion, in the pursuit of self-respect, Cook's performance is superb. On the D10 and the conference call, I believe that everyone thinks so.

Any successor to have all the advantages of Steve Jobs, but Jobs's great to cover up the outstanding performance of other executives.

The vice president of worldwide product marketing Phil Schiller Phil Schiller, senior vice president Bob (Bob Mansfield), Mansfield, senior vice president of iOS software sector, Scott Foster (Scott Forstall,), the CFO and senior vice president, Peter Oppenheimer GT32N SATA CD-RW DVD-RW (Peter Oppenheimer,), Internet software and services vice president Eddie Couey Eddy Cue, and Cook, etc., they have a lot of ability of Jobs. I believe, under the premise of inheritance Jobs heritage, they want to show fist, led Apple to a new height.

I said before Steve Jobs's death, he left to Apple's ultimate gift is the successor plan. Today, I am more convinced.

Cook is a very special business leaders, he does not seek outside expect to do some things that simply can not be achieved, but do a very good job. For us, this is the same truth.

Microsoft W in8 upcoming addition to one of the performance

June 14 [Thu], 2012, 16:59
Taiwan foundries, sources said, the average Win8 offer than Win7 high 20 to $ 30, the highest offer or even up to $ 100 is Win7 twice

the impact of the iPad, coupled with poor economic environment, the traditional PC manufacturers got hit. The face of Apple common "enemy", the PC industry chain will bet on this super pole, while the super pole this to achieve the goal of 40 percent market share this GSA-T20L year, but also with the help of the W in8 support. Therefore, the industry has been eagerly looked forward to Win8 can be described as.


However, recently the news from China Taiwan foundries Win8 the average license fee offer higher than that of Win7 20 - $ 30, the highest offer even as much as $ 100, double that of the Win7 offer. Such a high offer PC makers no doubt head poured poured cold water industry expectations wave of replacement or greatly reduced. Reporters learned from the Lenovo, Acer, Asus, Shenzhou computers and other vendors, they have not received such price information.

News called Win8 price is too high

Microsoft W in8 upcoming addition to one of the performance, the W the in8's price is the focus of the industry. PC manufacturers have want to Win8 price not too high, in order to help them cope with the current difficulties. In However, the the the to this strong aspiration of the PC manufacturers there are may fall through.

, According to a foundry in Taiwan, the W in8 offer an average of 20-30 dollars higher than Win7, the highest version of the quote even as high as $ 100. The news once spread, caused uproar in the PC ring immediately, causing PC makers nervous.

However, the relevant person in charge of PC makers Lenovo, Acer, Asus, Shenzhou computers, told reporters that so far have not received the relevant information, are skeptical of the authenticity of the message.

"I've heard this rumor, but can not confirm its authenticity." To reporters, IMS ResearchPC industry analyst Xu explained that "licensing fees and shipments are linked to shipments of the more preferential prices of the products more PC manufacturers, similar to the HP and the like are particularly large manufacturers, there will always be within the price of provisions. "

There OEMPC vendors with Microsoft is still in the game being in the short term is difficult to have accurate pricing out. Goldman's latest research report also made clear that, Win8 offer there are still many uncertainties.

OEM manufacturers can not accept

PC vendors have been hoping the W in8 allow them to become re-energized, therefore sensitive Win8 price. If the Win8 price is set too high, PC makers simply do not accept.

The market research firm ID C, Win Dow s licensing fees are too high, not only will impact the sales of notebook computers, will also affect the performance of the Microsoft operating system, the tablet PC market. Xu also admits that the licensing fees rose to $ 100, most OEMs will not be accepted. Replacement influx triggered by Win 8 may also be greatly reduced. The PC industry itself meager profits in recent years and prices continue to decline, the rate of decline is faster, profit is difficult to guarantee, naturally, difficult to sustain. "The ID of C in the study reported.

If the Win8 price set too high, the worst hit, no doubt super pole this. Super pole this was Intel and PC makers placed high expectations, Intel has set the goal of universal access during the year to reach 40% market share. But the super pole prices have been high above the consumers more difficult to accept. "If the price does not drop down, ultra very simply there is no future development." A PC manufacturers senior told reporters the South.

Xu, in the face of Apple, Microsoft and Intel are standing on the united front, OEM licensing fees are too high, both of which have an impact. OEMs must pay copyright fees to Microsoft for the purchase of Win8 chip to Intel paid. These two parts add up to the equivalent of over one-third of the pole of this total cost, If Win8 price is too high, PC makers simply GSA-T50N do not accept; in the flat, "they had been from the impact of the iPad, the cost of the Android operating system about $ 5 If W in8 price is also high, the outlook is less optimistic about it.

LinkedIn says last week 6.5 million user password is out

June 14 [Thu], 2012, 16:54
June 13 morning news, industry in the expert points out, the professional social networking site LinkedIn password leak may not lead to many account has been cracked, the reason is the thief by the lowest $1 only the price to sell the AD-7560A IDE/ATA CD-RW DVD-RW Burner password.


According to the Internet security service provider symantec said the price and the bank passwords in contrast, the price may be between $15 to $850. Symantec enterprise department President Francis DE Sue firm (Francis deSouza, said the stolen data according to the web site and the practicality of different, thus brought the price differences.

DE Sue firm points out, the stolen social network password to network for the thieves have only of limited value, the reason is, on the whole, the thieves can't directly from these accounts there make money. There hae been reported, if hackers can't in the web using LinkedIn stolen password, so will use them to into the other websites, the premise is using the same password users log on the web site of the different account.

DE Sue karzai said: "for the hackers's response to the actions should not be just change your LinkedIn, but in any password change use the same password on the website of the password."

LinkedIn says last week, 6.5 million user password is out, and be released in a Russian hackers web site. Previously, a report says more than 300000 user password has been declassified, and more password is decrypting process. LinkedIn users totaled more than 150 million, this means that was leaked user password is less than 10% of the total number IDE/ATA DVD+RW Burner Drive TS-L632 of users, but the affected users still a lot.

LinkedIn in June 7 published in the blog article says, the company has not received any user accounts and without authorization was logged on any have confirmed that the report, saying it has let any possible stolen password expiration.

LinkedIn says, the company is with the fbi cooperation, the user password was stolen in the investigation. The company spokesman Hani hanjour, drew the west (Hani Durzy) said at the time, a survey of LinkedIn is still at an early stage, still unable to determine and stolen the password corresponding email address is also has been stolen.

Last week, CBS's music web site Last. FM and online dating web site eHarmony user password are stolen, the two companies have suggested user password change immediately.

About hackers for, use social networking site LinkedIn, etc is one of the way to create fake accounts, and then the account with hackers together, and then began to wait. This connection will let the intruder monitoring the cracked account, and get the information about users to change jobs. Once the monitoring to this information, hackers may to its send an email, pretending to be a new colleague or human resources recruitment personnel, and if the user without doubt the click mail malicious links, then the computer will hackers control.

Intel is the latest Android market into one of the chip maker

June 14 [Thu], 2012, 16:50
When smartphones into many nuclear times, Intel has said Android system is still not suitable for multiple processors. Yesterday, Intel mobile and communications general manager mike bell said, through the internal tests show that, more than a single-core chip nuclear chip sometimes slow speed.

Intel is the latest Android market into one of the chip maker, it says other chip maker and failed to fully optimized Android, make suitable for multiple processors. At present, most processor manufacturers have started to trying to develop dual-core and four processors, and Intel just carry mononuclear Medfield Atom processor into the Android market. The company is all out against the English weida, qualcomm and other major of multiple processors suppliers.

However, Intel's words and not let a person feel to it is. Since the days from the PC, Intel and Microsoft is a good partner, both sides of "Wintel alliance" ruled the traditional PC Liteon DS-8A5SH mark et. With the arrival of the age of the mobile Internet, the entire technology industry to start with the developers, the cloud services, content manufacturer, the hardware manufacturers, system developers and retailers this close ecological system migration, many computer makers hope that Microsoft and Intel lend a hand, and help them to make up for the out of date has now slightly Windows ecological system.
