Battery News

Beginning in February, when a user reports that their laptop after upgrading to Windows 7 will always be recalled to replace the battery, even if the new batteries so. The survey, Microsoft said, Windows will detect the battery completely normal by 7, the problem is the battery or laptop users. Recently, Microsoft has some of this problem is a solution for laptops LG.

Microsoft KB981200 wrote “some improvement for LG laptop Windows 7 meter displays the battery system following warning message:” Please consider replacing battery. Even with the new battery, Windows 7 also display this fast. “Microsoft says the problem due to firmware LG certain portable system (BIOS) of a code defect, such as series R500.

Windows 7 to add a testing tool based on battery circuits and firmware to evaluate the overall performance of the battery, calculating the percentage of degradation. The overall performance of the battery if the user is only 40% of the plant, and then Windows 7 will be recalled to replace the battery.

LG laptops in part, the Advanced Configuration and Power Interface (ACPI) firmware is not properly initialized, can not use the method for BIF-capacity Battery proper design. Therefore, to assess the state of battery design capacity of the battery meter windows will be much larger than the actual capacity, so that the battery is fully charged is difficult to reach the rated capacity of 40% Windows 7 will always remember to replace the battery. The above version of Windows 7 in the installation of six would come.

Degli Studi di Roma La Sapienza university researchers in the March 12, 2010 announced the development of a new high-performance tin lithium-sulfur polymer-ion, the advantages of lithium-sulfur battery is a theory of chemical units Energy and energy density (respectively, 2,500 kg Wh-1, and 2800 Wh L-1), can overcome this type of chemical hinder the marketing of defects.

With the use of sulfur cathode and anode in lithium metal different from the conventional usual Jusef Hassoun, and Bruno Scrosati developed a lithium - metal-free lithium battery carbon disulphide using composites as cathode materials, tin and carbon composite materials as anode. The results of R & D have been published in “Angewandte Chemie” Journal of International Publishing, has been proved that the unit’s battery energy of 1100 Wh kg-1.

Lithium-sulfur is based on electrochemical reactions:

16Li + S8 8Li2S

The lithium-ion batteries used in the process known as a method of inserting the insertion of electrodes in the molecular ion being kept between the lithium-ion batteries, lithium-sulfur rely on a stable through a large number of sulfide ions using the multi-step redox sulfur. This process of storing, in theory, could reduce the restrictions on the structure of the electrode, so the other can increase the volume of similar capacity.

Conventionally, in the negative electrode, lithium discharge was dissolved in the solution, pricing, however. Intermediate depends on the stability of the sulfide ion electrolyte used in the solvent, the battery voltage and discharge capacity of the distribution of which depends on the use of solvents.

Also gel-like polymer membranes can be used to replace the liquid solution commonly used organic. Necessary to drive the electrochemical process of lithium-ion Li2S / C cathode supply, it can accept and release of lithium ions can be any material chosen as the anode to replace the lithium metal. Researchers use tin / nano-carbon composite, the weight ratio of Sn / 1:1 C. Improvement of Sn / C electrodes with a capacity of Li2S / C electrodes game, Sn / C has a high chemical stability.

Electrochemical process is basically a lithium-sulfide sulfur, lithium-ion battery output: 2.2Li2S / 2.2S → C + C 4.4 + 4.4 Li-e. Lithium-ion migration through the electrolyte to the anode, where the formation of alloys with tin: Sn 4.4Li + + / C + 4.4E-Li4.4Sn → + C. The whole process of Li - Sn alloy and elemental sulfur, tin metal and lithium sulfides generated reversibly.

Apple’s patent application will always lead to great interest in the market for their produce, and these patented technologies have also become concerned about the apple industry’s research and attention to Apple’s development labs of a window. Some patent applications tend to be more market triggered a shock on the market such as hot-a patented technology, the old iMac with a new touch-screen technology.

According to reports, the patent application technique is known as the shape of differential input devices (Shape Detecting Input Device), in 2004, made the original versions of the technology. The technology proposed, touch screen is not only a pointer / input device, but also a key / lock system based on the shape of the identifier. For example, retail store manager can simply be placed in a special imprint on the screen to verify his / her identity. When in use, Apple will be on the computer screen to set up a very sensitive touch areas, such lock / locking system will be fully protected.

It is reported that Apple is developing multi-point touch screen, and even reports that will launch later this year with a 22-inch touch-screen iMac. While Apple was originally released in 2004, its touch-screen desktop shape recognition technologies, and this patented technology to continue to submit an application in October 2009, which indicates that Apple’s touch-screen technology on the desktop has been engaged in research and development.

According to sources, Apple will be held as early as February 25 on sale of non-3G version of the Tablet PC iPad, but pre-sale is limited to the United States.

While Apple has previously sold the product before the official pre-sale, but the authenticity of the news is still questionable. Previously with the iPhone (mobile Internet) on the sale of all through the operators and their distributors.

Steve Jobs had said the release of iPad, non-3G version of iPad will be in about 60 days, that is, shipments by the end of March, but with a 3G module iPad will be shipped the next 1 month. But Apple has not formally announced iPad sale of a specific date.

If the iPad on February 25 on sale, then the date of sale than the planned one month in advance. This will help Apple’s market demand for a better stocking. Two weeks ago, has been reported that due to excessive user demand, Norway, 2 Apple distributors suspended iPad reservations.

Apple’s Web site information indicates that the recruitment of new Apple iPad is planning to add photos and video capture capabilities.

Apple recruiting for this position is an interactive media group Media Systems Division of the quality assurance engineers, this post will focus on the “iPad media business.” Recruitment information display: “Media Systems team is looking for a software quality engineer. The engineer must possess a strong technical background, can be static images, video and audio capture and playback test.”

According to job descriptions, the engineer required to assist in the development team, test system performance, and to develop appropriate tools for testing. Job description, said: “(candidates) need to be familiar pictures, video and media file formats, and interest in this regard. For the following has extensive experience in imaging technology, including but not limited to auto white balance, color correction, auto exposure and frame the rate of adjustment. ”

Many observers believe that do not support the camera head is iPad is an important defect. However, iPad package structure revealed that the product has a space available to install a similar notebook with the Apple iSight camera. Therefore, insiders speculated that Apple for some unknown reason the temporary removal of the camera, but in the official shipping version will join the camera.

Toshiba is developing the common images, that is converted to 2D images of 3D imaging software technology, in its latest platform, C ELL applied.

3D is the second LED backlight technology, the next important technology affecting the entire market. D islaySearch estimated 3D displays shipped in 2018 amounted to 22 billion U.S. dollars, while the 3D-Ready TV shipments will reach 4 million units 6, 1000.

Lack of 3D content is constraining the core issue of industrial development. To this end, Matsushita Electric and the United States the largest satellite TV service provider D irecT VG roup partnership, to be launched in June this year, three 3D channels. Sony and Discovery Communications, and IM AX in the United States joint venture to build the first dedicated 3D television network, while the Samsung is a global exclusive with the DreamWorks partnership.

This reporter has learned, C ELL TV is equipped with a CELL chip, the chip from Toshiba, Sony and IBM co-developed by a 3 Broadband Engine. IBM’s supercomputer will be used inside the Sony PS3 game console of its implantation, Toshiba will offer the chips used in the TV inside. With Intel’s dual-core processors compared to the processing speed of the latter 10 times.

Yu village known to history, Toshiba TV in considering the use CELL to achieve super-resolution for 3D imaging technology. 2D-3D conversion technology to take advantage of television and other common image, according to the scene inside the information and motion parallax, etc. to create a virtual 3D TV using three-dimensional images. CELL chip’s processing speed to complete this task.

Satjiv Chahil, the marketing impresario who helped Hewlett-Packard seize the top spot in the global PC market, is retiring.

Chahil, the chief marketing officer of the Personal Systems Group, leaves HP Pavilion dv2000 battery (HPQ) at the top of its game. Since he joined the company four years ago, the company has taken share from rivals such as Dell (DELL) through a combination of operational efficiency and savvy messaging. For example, under Chahil’s watch HP launched an ad campaign called “The Computer Is Personal Again” featuring celebrities such as Serena Williams, Jerry Seinfeld, Vivienne Tam and Jay-Z.

In an industry where executives have traditionally focused on component costs rather than design and presentation, Chahil, 59, has always been something of a rebel. After stints at IBM and Xerox, he joined Apple (AAPL) in the early 1990s and was a major advocate for putting CD-ROM drives into computers. (It seemed like a wild idea back when floppy disks ruled.)

Later at Sony (SNE), he helped establish the VAIO line. At Palm (PALM) he boosted the style quotient of the brand, and changed the naming system for the handheld computers. Roman numerals were out – names like “Palm 500” and “Palm 700” were in. (Chahil borrowed the naming system from luxury cars.)

Chahil also started working with a guy named Todd Bradley at Palm – and that relationship would bring him to HP. HP CEO Mark Hurd hired Bradley to lead a turnaround of the company’s PC business. And when Bradley needed someone to run marketing, he tapped Chahil. There he has led an image turnaround for the PC business, using his Hollywood connections and skillful handling of the press.

What’s next for Chahil?

For now I hear he’s helping to interview his replacements, and plans to step down at the end of the month. (Until the spot is filled permanently, one of his deputies, David Roman, will fill in.) For the next year he’ll serve as a consultant to the company. I also hear that he’s interested in spending more time on causes like education and healthcare, perhaps in his native India.

While I know those issues are close to his heart, I’m not sure I believe that’s all he’ll be doing. The guy’s always thinking about the next big idea – and with all the buzz about iPads and smartphones, it’s hard to imagine Chahil sitting it out for long.
