Tablet PC JooJoo delivery time postponed to March 25

Friday, February 26th, 2010

Science and technology blog TechCrunch Tablet PC development issues on the result of a dispute in Singapore start-ups Fusion Garage Friday announced that, because of production problems, the company’s JooJoo Tablet PC shipments will be delayed.

Fusion Garage at first jointly developed with the TechCrunch Tablet PC. TechCrunch founder Michael Arrington (Michael Arrington) first proposed this idea, and the product name CrunchPad. The product was originally scheduled for release November 20 last year, but as in the previous few days, a sudden rupture of bilateral cooperation. Fusion Garage announced that it would be sold separately this Tablet PC, and re-named the JooJoo.

Earlier this month, Fusion Garage’s JooJoo Tablet PC has been fully put into production, according to the original plan, the product will be shipped this month. But the company last week, found that there are some production problems, and quickly diagnose and fix. According to the latest plan, JooJoo will be shipped March 25.

It is reported that the production problems with the capacitive touch screen, sensitivity of the sensor. Fusion Garage that will provide users free of charge for all scheduled JooJoo accessories to make up for losses caused by delayed delivery.

Fusion Garage Malaysia GSL Group recently entered into an agreement which is responsible for JooJoo Tablet PC production. The Fusion Garage can be saved to virtually all production-related costs, but the need for GSL Group provides JooJoo into sales.

Fusion Garage is also due to delivery delays apologize for any inconvenience caused to the user.

Electric Vehicle Battery Maintenance 6 Skills

Wednesday, February 24th, 2010

Right now, electric cars because of its advantages such as light pollution deeply consumers, while the mileage to measure the length of a consumer good or bad the quality of electric vehicles, one of the main criteria. It is worth mentioning that a large number of electric vehicles in the quality of complaints, accounting for over 95% of the battery problem, because the battery is to determine the length of electric vehicles an important factor in the exercise of mileage. Then the normal maintenance of electric vehicle batteries should pay attention to what the problem?

“Times can be battery Rehabilitation Center” maintenance of professional knowledge on the battery and gave specific description.

Technique, when a non-loss storage electric

When the battery in storage is prohibited in the state power loss. Loss refers to the battery power status is failure to make timely charge after use. Stored battery power status in the deficit, it is prone to sulfate, lead sulfate crystals attached to the pole plate, plug the electric ion channels, resulting in insufficient charging, the compaq Presario R3000 battery capacity decline. Idle state electricity loss the longer the more serious the damage to the battery. Therefore, the battery idle, we should add power once a month, so that can better maintain battery health.

2 regular inspection techniques

The use of process, if continued line of electric cars, a sudden drop in mileage in a short time more than ten kilometers, it is likely that at least one battery in the battery occurs off grid, plate softening, plate active material shedding phenomena such as short-circuit . At this point, the battery should be repaired in time to professional organizations to inspect, repair, or distribution group. This could be relatively extended battery life, maximize cost savings Inspiron 700m battery,Inspiron 710m battery.

Tips to avoid the three high-current discharge

Electric car start, manned, uphill, please help with the pedal as far as possible to avoid the momentary high-current discharge. High-current discharge easily lead to lead sulfate crystallization, to the detriment of the physical properties of the battery plates.

Charging time to master the right skills 4

The use of the process, should be based on the actual situation accurately charge time, refer to usual frequency of use and the mileage situation and pay attention to the capacity of the size of the battery manufacturers to provide instructions, as well as matching the performance of charger, the charge current to grasp the size of the charging parameters such as frequency of . General, batteries are charged at night, with an average charging time of 8 hours. If the shallow discharge (charge mileage is very short), the battery will soon be filled, to continue charging overcharge phenomenon occurs, leading to cell dehydration, fever, lower battery life. Therefore, the battery in order to discharge a depth of 60% -70% of the best to recharge a battery, the actual use can be converted into a riding mileage charge based on actual conditions necessary to avoid damaging charge.

5 tips to prevent exposure

Electric vehicles is prohibited under the sun exposure. Battery temperature is too high internal pressure makes the environment through increased cell pressure limiting valve was forced to automatically open a direct consequence of water loss is to increase the battery while the Inspiron E1405 battery cells will inevitably lead to excessive water loss decreased activity to accelerate the plate softening, charging shell body heat, since the shell drums, distortion and other fatal injuries.

6 tips to avoid the charging plug fever

Charger output plug loose contact surface oxidation phenomena such as charging plug will cause fever, fever for too long will lead to short-circuit charging plug, direct damage to chargers, lead to unnecessary losses. So, found out that the situation should be promptly removed oxides or replacement connector.

Sony: Wii game developers are moving away from turning PS3

Sunday, February 21st, 2010

Nintendo Wii is perhaps the most popular console of this generation. However, this game has an important issue for its success may be far-reaching impact. This problem is only the first party game software can be run very well on this platform.

Sony believes that the market research firm NPD Group latest on Wii games sales figures indicate Sony gaming platforms have a good prospect. Sony is responsible for the relationship between publishers, senior vice president Rob Dyer said, seeking more return on investment of third-party game developers are moving away from Nintendo’s Wii turned to Sony’s PS3.

Dyer said, publishers say that they are not prepared to use the resources in the Wii console area. In my work, we have to compete with Microsoft and Nintendo. We compete for resources. So, in my conversations with publishers, I asked them “You have the resources be used where?.” The past, the answer is, “You look at how popular Wii game console? Or how popular DS game? We should use the resources here.” They did so and realize that third-party products in Nintendo gaming platform is selling well.

Dyer said that because of these games publishers to recover these resources and these resources are used in our gaming platform. Sony will be able to provide you with exclusive content. We will invest more in this regard engineers to figure out how to maximize the use of Blu-ray technology, and from the PS3 console to get more revenue.

Economical and practical solution for backup battery monitoring

Wednesday, February 10th, 2010

Support the infrastructure of modern society must be based on a very high reliability of operation. Internet and telecommunications switching center server farms in order to ensure nearly 100% of the “trouble-free run-time” or system availability, they mostly rely on a very mature technology – lead-acid batteries, while the data storage center are used in high-tech. Typically, these key nodes, and many other important sectors are equipped with standby power, standby power supply is generally the first level inverter, inverter pairs of VRLA (VRLA) battery or a similar performance, sealed gel batteries assembled battery Section of power conversion.

The reason why traditional techniques are widely used, there are many reasons, especially lead-acid batteries affordable, but also with outstanding reliability. But while great but not perfect. VRLA battery life is limited (generally 12 years design life), often mission-critical systems using this battery as a backup power supply, but changed regularly. Failure may indeed occur. In a typical standby power systems, the role of the battery as its name – they always maintain a fully charged state of waiting for the main power failure. And the fully charged state of continuous small current through the “float” charge to maintain. If the float current is below a set limit, then the battery inside the gases produced by electrolysis will be re-chemical combination. In this case, a single battery float voltage is even slightly higher than the standard value of 2.27 V, may also damage the battery. Slightly over-voltage will cause precipitation of the electrolyte capacity of more than Recombination more gas, these gases are not handled through the overflow valve. If the battery temperature is too high, even if the charging voltage is appropriate, can lead to electrolyte loss.

Other failure modes include early sulfation, very bad columns and grid connection, grid connection plate and the bad, electrolyte stratification and grid accelerate corrosion. There is yet another, though a small but catastrophic failure modes – thermal runaway, which is peculiar to VRLA gel batteries, and a failure modes, can lead to burst into flames. The only way to prevent thermal runaway is to monitor the internal temperature of the battery.

Simply monitoring the battery voltage on the detection of lead-acid battery capacity decline in the role is very limited, it has been recognized throughout the industry. When the battery performance is declining, it is usually presented is that the nominal voltage, until the release of large currents can only apparent, but when its capacity has been severely reduced voltage drop prematurely. By measuring the proportion of electrolyte to determine the exact battery status, the method of the VRLA or sealed gel batteries does not apply; routine, the test battery used in the only way is to discharge the battery pack to a controlled state of the following, but this approach need to stop using the battery. In addition, the depth of discharge also reduces the life of lead-acid battery; in on a regular basis to conduct its backup battery discharge test, as well as its main power supply with high reliability of the system, most programs use this test to determine battery life.

Recently, continuous monitoring can be a non-intervention electronic method can detect a single cell near the failure state, this method can not only save costs, while maintaining overall system availability. The predecessor of such systems is usually measured cell or battery pack (battery industry term which means that within the shell in the same package multiple battery) voltage – despite its limitations is well known – with charge / discharge current and ambient temperature. Some systems attempt to measure or guess the battery internal resistance, its effectiveness varies.

LEM’s Sentinel system is dependent on the basic parameters of a simple analog measurements of change leading product has now grown to the first three generation of the Sentinel III. It is custom-designed single-chip SoC (System on Chip) IC on the integration of analog and digital technology. The device configured in a measured terminal voltage, the battery internal temperature and internal resistance of the module, can provide accurate measurement results for the cost again in most of the backup system configuration can afford within the budget of the system, it is the design of a key elements.

Dell does not deliver in time lead to anger consumers

Monday, February 8th, 2010

Dell’s failure to timely delivery of products during the holiday shopping season, but rather to provide consumers a “holiday card” (Holiday Card) to be placed under the tree, which triggered the anger of consumers.

Dell on December 17 issued a statement saying that “the growth in demand, and certain parts in the context of the entire industry out of stock,” the reason, the company is in the order delay dilemma. Dell digital media manager machaca (Lionel Menchaca) said: “We apologize for the inconvenience, especially at this time.” He said some of Dell’s products because of memory and large capacity hard disk out of stock items are affected.

However, consumers still delivered the performance of Dell’s getting worse and worse over there complaining. One consumer said: “Dell has been in the order expires two to three weeks until after the delivery. So people, if the end of the 11 orders, then the Dell promises to deliver in mid-December; but the date approached, Dell will postpone delivery of one week; week later, Dell will be delayed a week. in some unexplained reason, Dell will be to some extent forgotten how to respond to consumer e-mail, so that they clueless about what had happened. ”

Dell’s side has not yet reached for comment.

Apple iPad impede Intel chips into mobile phones

Thursday, February 4th, 2010

Intel blocking

Intel said the first smart phones using its chips will be available later this year, Intel hopes to occupy a place in the wireless network market, reproduce Intel Internet in this area have been tremendously popular to create a brilliant, almost chip is currently Intel Internet access to this market leader.

But analysts said that the British Hill & Knowlton, Marvell, and Qualcomm and other chip maker ARM-based design, introduced a cheaper, more energy-efficient processors, Intel and the increasingly fierce competition in each company.

Wedbush Morgan analyst Patrick Wang said: “They (Intel) does not Chupin the history of such chips. Their past lack of success in this direction, but now trying to reach encompasses this area.”

Apple’s design team and its recent acquisition of PA Semi’s chip developed A4, A4 understanding of the industry is limited to: the chip enable iPad tablet computer battery has a very long life time, speed and performance are comparable to competing products on the comparable.

Apple to conduct independent research shows that more targeted chip design concept, and perhaps more suited to the rapid development of the mobile phone market, rather than Intel’s exhaustive strategy.

However, 80% of the world’s personal computers based on Intel’s x86 chips, more powerful processors, and analysts say, Intel’s main obstacle is how to put aside the technology start all over again.

Wang said: “In a press conference held prior to Intel and Development Forum, you can see are designed to dull, the product heavy, short battery life of mobile network equipment. Makes them worried.”

Intel-based tablet notebook computer market over the past decade, has not been a big success. Apple Mac in its series of personal computers and servers using Intel chips.

The new competitive areas

With Intel since 2007 specifically for the Internet and handheld Internet devices to this wireless product design processor, a strong move into mobile device market. Intel Atom processor, available only from 2008 onwards, a strong occupation of low-cost Internet access to this market, the equipment to run the system just to run Microsoft’s Windows operating system, users can check e-mail, Internet and the preparation of documentation.

But analysts expect online sales growth will slow this, Intel hopes to electronics manufacturers to prove that its chip is a new portable electronic products the best choice.

Apple iPad is expected to trigger consumer tablet PCs and strong demand for electronic readers. IDC analyst Bob O’Donnell said, IDC expects sales of Apple iPad will reach 3 million -400 million, while the Internet is about 35 million of this amount, laptops for 165 million.

But issues such as tablet PCs and other mobile network equipment sales are expected to increase by several times in the next few years, chip manufacturers will launch a new round in the field of competition.

Apple iPad in the abandoned Intel’s products, while the majority of tablet PCs and smart mobile phone manufacturers had elected to use ARM architecture chips.

“For Intel, this implies that the calculation in the computer field, there are a lot of space does not need their x86 technology,” Auriga analyst Daniel Berenbaum said.

He indicated that the majority of smart phones and mobile device manufacturers last year’s flagship product is to look at video, listen to music, the Internet, browse pictures and other simple functions, which are not very much power, but also do not need Intel hallmark of the energy-saving, high – performance and multi-tasking technology.

Asia-Pacific super-notebook shipments this year surpass the United States

Tuesday, February 2nd, 2010

IDC data show that notebook shipments this year’s Asia-Pacific region will surpass the United States and will surpass Western Europe in 2012.

IDC data show that this year’s Asia-Pacific (excluding Japan) market, notebook shipments will reach 48.85 million, thus surpassing the United States market shipments, but still lower than the Western European market, 53.46 million.

However, in the next few years, notebook shipments in the Asia-Pacific market will remain at 25% or 30% As in 2011 will reach 62.55 million, close to 63.42 million in Western Europe. By 2012, is expected to go beyond Western Europe.

IDC pointed out that China and India is to promote the Asia-Pacific notebook market, the main driver of demand growth. In the notebook manufacturers, the 2009 market share of Lenovo in China, 25% to 30%, topped the list. However, in the entire Asia-Pacific market, HP ranked first.
