33% of battery failure, Amoi lithium batteries “serious problem”

33% of battery failure, Amoi lithium batteries “serious problem”

Learned from the Shanghai Quality and Technical Supervision yesterday in its latest mobile phone battery monitor checks in the city of production and sales of non-original battery is poor overall quality of the sample pass rate was 66.7%, security needs to be improved. Among them, Amoi Electronics Co., Ltd., Shenzhen Super Power Electronic Co., Ltd, Song Xun Da Zhong Ke Electronic (Shenzhen) Co., Ltd was ordered to rectification.

Non-original mobile phone batteries, also known as “compatible battery.” As the price of the same specifications than the original battery cheap, non-original batteries currently on the market share is increasing. The Shanghai quality and technology supervision department had taken 15 different cell phone batteries, of which 10 types of compliance, 5 failed.

Safety non-original mobile phone batteries failed the outstanding quality. Testing, the nominal power of Shenzhen Super Electronic Co., Ltd production of “super-power links” lithium-ion battery, Amoi Electronics Co., Ltd. Production “Amoi” lithium polymer rechargeable battery and Song Xun Da Zhong Ke Electronic ( Shenzhen) Co., Ltd production of “TSD” lithium batteries, the thermal shock test in the process of explosion determined by regulators as a “serious problem of quality products.”

In addition, some non-original mobile phone batteries “standby current”, “current call” and other indicators of substandard, the direct result of the standby time, talk time was shortened.

Experts pointed out that mobile phone batteries on the market price difference between the poor, the quality varies greatly. From a security point of view, genuine mobile phone batteries installed within the general over-current protection device, such as abnormal in the case of short circuit can be automatically cut off the circuit, to avoid damage the device. If the charging process, the cell phone batteries severe heat, smoke and other phenomena, we show that the battery is fake.

BlackBerry Tablet is supposed to end with 1 GHz CPU

BlackBerry Tablet is supposed to end with 1 GHz CPU

Other features of the device includes a 7-inch touch screen. The launch of RIM will prefer early 2011 to late 2010. In addition to the Tablet have two cameras and video conferencing support.

Research In Motion allegedly bringing this year with a Tablet BlackBerry OS on the market. The unit shall have a 7-inch touch screen and a 1 GHz processor from Marvell Technology. This is clear from an analysis of Ashok Kumar, an analyst and managing director of investment bank Rodman & Renshaw.

"RIM tries to bring forward the start of the 7-inch touch-screen tablet by early next year to the end of the year," Kumar said in the report. The unit will be by two cameras for video conferences - one on the front and a distinction on the back - from the competition. RIM declined to comment on the report.

The BlackBerry Tablet iPad would be in direct competition with Apple, which has been available since April. RIM in the smartphone market in competition with the mobile phones and Storm Storm 2 with Apple’s iPhone.

The CPU could be in the BlackBerry Tablet Marvell’s 1-GHz processor, 610 Armada are used, which is designed for tablet, mobile Internet devices and e-book reader. The chip supports the playback of full HD (1080p), cameras with a resolution of up to 16 megapixels and 3D graphics functions.

Marvell is already working on a Tablet PC for the nonprofit project, One Laptop per Child. The XO tablet with Marvell chips should appear in 2011.

In his report, Kumar is also a possible shortage of supply of components for iPhone and iPad: "The demand is behind the offer. In both the touch screen equipment remain a bottleneck." Even if the production capacity increases and the number of defective displays in production at LG Display sinking, it is unlikely that global iPhone demand could be met by year end.

Kumar expects the iPad-sales will double to 27 million in 2011. His estimate for the iPhone is at 70 million units sold next year, above the expectations of other analysts who come from 50 million units.

Marvell processors are not only in the XO-3 from One Laptop per Child, but apparently also in a BlackBerry from RIM Tablet used (Image: OLPC).

Researchers are developing the world’s thinnest trace

It is only visible under the electron microscope. The thinner the train, the faster the data transfer works. The technology could be for the miniaturization of electronic components is essential.

Researchers have developed the thinnest trace of the world.

Scientists have succeeded to produce the thinnest trace of the world. The metal threads are so fine that they are visible only under the electron microscope. The project researchers from the University of Cambridge, the South Korean Sungkyunkwan University and worked at the Institute of Materials Research and Engineering (IMRE) in Singapore.

The track is 7 nanometers high - about 14,000 times thinner than a human hair. The variations within the train is 2.9 nanometers, which is below the target of 3.2 nanometers, which the researchers had set for 2010. A lower volatility makes faster data transfer possible, leading to lower energy loss through heat.

The ability to produce such thin metal thread, be decisive when it comes to the downsizing of electronic components, according to the press release (PDF) of IMRE. The traces could be used as compounds in extremely small circuits are used.
