Smartphone Battery Technology Being Developed Improves Battery Life by 50%

New battery technology being developed for mobile devices, could extend battery life up to 50%

Smartphone technology has advanced at a head-spinning rate over the past few years, and our mobile devices can do more than even the most powerful computers could just 15 years ago. Unfortunately, the joy and convenience that we get from these devices are brief and fleeting, because we find ourselves running for our chargers and power outlets every few hours. Battery technology has struggled to keep up with the demands of 4G technology, larger displays and powerful processors, but that could soon change.

Researchers at the University of Michigan have been working on a new battery that helps maximize smartphone battery life up to 50% when connected to a Wi-Fi network. While it sounds very limited in its application, it could open up the doors to improving battery life in other areas, like cellular network connectivity.

A report from CIO says:

When Wi-Fi-enabled modern smartphones are connected to Wi-Fi and other wireless networks, they’re constantly communicating with those networks to determine if new data, such as e-mail messages, need to be “pulled down” and delivered to users’ devices, according to the researchers–which is why it’s a good idea to turn off your Wi-Fi radio when it’s not in use. So Shin and his student set out to find a way to decrease the amount of power required for this communication, or “idle listening,” between Wi-Fi devices and Wi-Fi networks, and they came up with [“”Energy-Minimizing Idle Listening” (E-MiLi)].

The technology will be demonstrated later this month, and while it is still in its infancy, its implications for use with 3G and 4G networks are exciting. Just imagine being able to leave home in the morning without your battery charger or a spare battery, and make it back for dinner with plenty of juice to spare. One can dream.

Top Two New Must-Have Laptop Accessories

Good laptop accessories are stuff that can completely change the mobile computing experience. That’s why were are always on the lookout for new and interesting add-ons for your laptop. So today we bring you two new accessories that will definitely help you get the most out of your laptop.

Almost all netbooks that are in use today have heating problems. That is not to say that they overheat but the heat is definitely enough for me to keep the laptop away from my skin lest it should get burned! This is a problem that is most commonly associated with the times when the computer is being used for processor heavy tasks such as gaming or video rendering, etc.

The high speed of modern processors and internal GPUs give off a lot of heat which results in a considerable rise in the temperature of the whole machine. Sadly enough, the generation of heat also slows down speed of the machine. As a result, one may even experience problems in viewing high quality graphics and this can be quite a bother when playing games on a notebook. One way one can avoid such a situation is by using a notebook cooler.

Cooler Master has recently introduced a new notebook cooling product called the NotePal Infinite Evo. It helps in bringing down the temperature of notebooks using the pair of fans that generate cool air that is let out through slots on the top of the device. The air cools down the bottom of the notebook. Each of the two in-built fans measure around 80mm and the device is capable of cooling notebooks that measure up to 17-inches — meaning it can cool most of the largest of mobile computing behemoths out there. To serve as an icing on the cake, the cooling device also allows the screen of the notebook to be lifted in order to offer a more comfortable viewing angle to the user. The NotePal Infinite Evo is connected to notebooks through a USB port and comes with a three-port USB hub on its side so that the user doesn’t need to compromise on the already scanty available ports on the notebook in order to accommodate the cooler. More importantly, at £30 the Evo is quite a reasonable buy.

Toshiba pa3534u-1brs laptop battery brand new 4400mAh Only AU $62.07

Acer Aspire 6930 laptop battery – Brand New 4400mAh Only AU $65.29

It’s not just Cooler Master that has come up with a cool add-on for laptops. Recently, even Altec Lansing has come out with its latest device – the Orbit USB Stereo speakers that work on notebooks. These speakers can be connected to the notebook using the notebook’s USB port and this is the connection through which the speakers receive their power supply. To make portability easier, the speakers can attach to form a singular unit that makes carrying these around a lot simpler. When they are attached to one another, the cord of the speakers gets contained within the unit. The expected price of the speakers is also £30.

Top 10 Batteries Usage Tips, Hacks and Tricks

The gadgets you love don’t always love you back—at least when it comes to battery life. But you can get more from your laptop, your iPod, your phone, and other devices with these 10 techniques.

10. Turn C batteries into Ds with quarters

Only a few things ever need D batteries, but who has them handy when you need those things? If you’ve got some slightly more handy C batteries around, you only need a few quarters to turn them into makeshift Ds. You won’t get the same longevity, and you’ll have to part with up to $1.50 for a bit, but it works, and it might just turn you into the family hero when you rescue that seemingly useless big-lens flashlight.

9. Keep your iPod “held” and updated

If you haven’t hit the “Update” button since you got your iPod, old or new, fire up iTunes and do so—the newest firmware, in many cases, can boost your battery life. Once you’ve done that, run through Playlist Magazine’s battery saving tips, which include keeping backlighting, the equalizer, and Sound Check features off when they’re not needed. Also, keeping the “Hold” switch in place when you’re not actively using it saves you from accidentally playing your whole collection, and wasting another charge cycle.

8. Get serious rechargeable batteries (and a battery charger)

It’s a help to the environment, and your checking account, to use rechargeable laptop batteries instead of letting your Wii remotes and other gadgets eat through AAs. But the grocery store brands and accessories often don’t seem worth the hassle. Blogger Jeff Atwood does know what works, though, and he details the circuit science and recommends the good stuff in the post linked above. If you’re stuck with Energizer and Duracell choices, though, here’s Gizmodo’s faceoff of the big brands.

7. Turn off your digital camera’s screen

Having a view of the whole scene you’re shooting is one of the digital camera‘s big advantages over film-based models, but powering that tiny little LCD takes quite the toll on your little camera batteries. If you’re running low, or know you’re going to be without a recharge for some time, turn the screen off and shoot through the optical viewfinder. You’ll save battery time, and might find a new perspective on focus and framing.

6. Watch movies from hard drives, not DVDs

Simple, sure, but not always obvious. On many planes and trains, laptops serve as little more than portable DVD players with bigger screens, but forcing your laptop to spin the discs and read from them eats up more power than reading a file off a hard disk—or, perhaps even better, a USB drive. How to get there? We recommend HandBrake for most any system, though Adam’s got a pretty good thing going with his (Windows-based) one-click DVD ripping solution.

5. Extend your not-so-hot iPhone life

A lot of lists out there offer to help extend your iPhone‘s battery life. This one’s a lot like them, except it’s written by our sibling site Gizmodo and based on extensive testing done during the run-up to the iPhone’s launch. And it goes so far as to suggest what the others don’t—playing games with 3D and vibrate, for example, is a power killer, both in actual juice and in how long you’ll end up playing without realizing you’ve been sucked in. And if you’re just checking weather, emailing, and making calls, keep your 3G switched off until it’s needed.

4. Stash your gadgets out of your pockets

It’s the most natural place in the world for your cellphone or iPod, but the heat your pocket picks up from, well, your hips can decrease the overall life of lithium-ion fujitsu laptop batteries. Not so much that you absolutely have to get one of those I’m An Important Person belt clips, but if you’ve got a coat, purse, or other place to put a battery-powered gizmo, consider offering it a little more ventilation than your body-warmed cotton wraps. While you’re thinking cool, try stashing your notebook batteries (just your batteries, mind you) in the freezer if you’re trying to conserve every last drop while you’re away from your batteries charger

3. Get long-term battery life

An inquiring reader asked how to keep his batteries delivering on-the-go power for the long haul, rather than watch his investment be eaten away by age. As is so often the case, our readers came right back with answers. A MetaFilter thread linked by one helpful reader suggests using the battery fully if you’re going to use it, then re-charge when it runs down. A Battery University link offers more tips, and Apple’s guide to batteries suggests a few tips on what to do with unused or spare batteries—store them in a cool place at about 50 percent charge, for instance.

2. Make your system smarter about power

Windows and Mac OS X both know when you’re using a laptop, and presumably want to help you save power. Except, in the case of the Mac, sleeping and hibernating isn’t done with remaining battery power in mind, and on Vista, well, all those Aero effects and background processes suck up power too quickly. Enter Vista Battery Saver, which kills the Aero effects, sidebar widgets, and other power sinks, and SmartSleep (OS X), which gradually transitions from sleep, to sleep-and-hibernate, to full-on, session-saving hibernate as you start winding down from 20 percent charge. Both are nearly necessary downloads for road warriors lugging either OS around.

1. Recalibrate a laptop battery to regain life

Fujitsu lifebook t4210 laptop batteryFujitsu laptop battery >>  Fujitsu lifebook t4210 battery

It’s a shame, but laptop batteries can lie to you about how much juice they have, or can really hold. The New York Times explains in a Q & A (look halfway down the page) the most straight-forward means of getting the real truth. Turn off all your interrupting apps, like screensavers and the like, put your computer to sleep, and plug it in until you know it’s good and charged. Then turn it back on, make sure your power settings are such that the system won’t try to sleep or hibernate, then run your computer all the way down on battery power. Charge it back up one more time, and you’ll know whether you really need to start shopping at Laptop Batteries Company, Discount Laptop Batteries Shop or check with your batteries manufacturer to get a new lithium stick.


How do you get more power from your battery-powered gadgets? Whether it’s a laptop, a phone, or something we haven’t covered here, tell us (and link the how-tos) in the comments!

Can Mango really power Windows Phone to the top?

Windows Phone’s 7.1 Mango update has dominated headlines this week. And rightly so. The updates make the already excellent mobile OS even more appealing, with brilliant advances in terms of Bing search, improved live information delivered to the homescreen and full-on Twitter support.

And that’s before we even get to the belated announcement of Windows Phone Marketplace’s arrival online, offering punters the chance to buy and sync apps on the web as well as on their phones.

But while on paper, and in the flesh, these updates are undoubtedly impressive, Microsoft still has some big work to do to get itself to the top. New partners, in the form of Acer, ZTE and Fujitsu will help globally, if not in he vital US and European markets. But there has to be a question about why this update isn’t being released until autumn.

There is some logic behind the move. Microsoft wants to ensure devs have the chance to bring the new features to existing and future apps, hence they’ve released the SDK now. And trailing operating systems is nothing new: Google did it with Ice Cream Sandwich at I/O earlier this month and Apple will do the same with iOS 5 in the next fortnight.

However, the fear is that Microsoft will take three months to get it ready for devices, only for manufacturers and networks to take their own sweet time testing it and getting it out into the wild. This has already happened with the Big M’s previous Windows Phone update, causing much embarrassment and awkward headlines for the Redmond batteries company.

On top of this, Microsoft will be releasing its Windows Phone update around the same time that Apple updates current iPhones with iOS 5 and rolls out the sequel to its best-selling blower. Just a few weeks later, Ice Cream Sandwich will land on Nexus phones, with new Android hardware doubtless not far behind.

This is tough on Microsoft. Rush the release and risk getting it wrong. Hold it back and they’ll have to go mano-o-mano with the biggest players in the smartphone space. Of course, its Nokia Windows Phones will cause some buzz and generate sales. But will they be anywhere approaching the volume it needs to start pushing up analysts’ smartphone charts?

It’s highly unlikely, especially as Google and Apple look to redouble their efforts in the run up to Christmas. Mango looks the part, just as the first version of Windows Phone 7 did. But there has to be the fear that this will remain, for the time being at least, a niche concern for discerning mobile users.

Which is the best tablet pc for you

Looking back in time, there effectively were no consumer tablets in the beginning of 2010. Sure, Microsoft had Tablet PCs for nearly a decade prior, but these were heavy, had relatively short battery life and suffered from a desktop operating system that wasn’t optimized for mobile use. It was Apple’s original iPad, debuting on store shelves in April of 2010, that kicked off the current tablet frenzy. Since then, companies have jumped into this hot market, hoping to score some of the estimated 53.5 million tablet sales that research firm IDC expects this year alone.

Tablet market recap: how did we get here?

It took time for iPad competitors to appear, however, as Research In Motion, HP, Samsung and many others scrambled to create or use new mobile operating system for such devices. At the Consumer Electronics Show this past January, a full eight months after the first iPad arrived, a slew of Google Android tablets were shown off, and I had my first hands-on experiences with RIM’s BlackBerry Playbook. And just last week, HP launched its TouchPad with the webOS system. Of course, while all this tablet activity happened in the first half of 2011, Apple improved the iPad with a successor device that’s even faster than the original, has two cameras and can stream media to HDTVs.

Fast-forward to present day, and now there are a number of tablet choices that simply didn’t exist 14 months ago. It can be overwhelming to pick and choose, because each tablet platform and device has certain pros and cons, even as most have $499 starting prices. I’m in the unique position of having at least one tablet from each platform in hand right now. After using them all in the past few weeks and months, I can’t tell you which tablet is the best for you, mainly because everyone has different needs. But my hands-on usage of these devices can offer insights as to which have standout features and which still face challenges that might not be acceptable to you.

Apple iPad: best all-arounder

The iPad has the advantage of successful “first mover” status, so when many consumers think tablet, they think iPad. And why not? Apple prepared users for the iPad by honing the iOS operating system since 2007. Put another way: If you know how to use an iPhone or iPod touch, then you already know how to use an iPad; there’s no learning curve involved. Aside from the ease of use, the iPad has not only the most apps available to it, but it has all of what I’d call “top-tier” titles. I’d be hard-pressed to think of a killer app from another platform that doesn’t already exist for the iPad.

Apple’s iPad has also provided the widest array of media options for the longest time. iTunes natively has support for major music labels as well as many movie studios and TV content providers. Where it falls short in these areas. it makes up for in the apps: Netflix and Hulu Plus, for example, add content Apple has no license to provide, and these types of apps have been slow to appear on other mobile platforms. Add in simple media streaming to an AppleTV through the AirPlay function, and the iPad makes for a great media solution over competitors.

While there’s much to like. and the iPad is a known commodity with great application support, it’s not for everyone, nor for every situation. Earlier this year, I found I preferred to carry a smaller tablet outside the home and I dumped my iPad for that reason. I later picked up an iPad 2, but my use cases for it are limited to around the house: in bed, on the couch or at the kitchen table. Many consumers tote their iPad all the time,o58itf and while you can take it anywhere, it’s not as easy to use everywhere as a smaller device is. People looking for more portability might consider a 7-inch Samsung Galaxy Tab, BlackBerry Playbook, or HTC Flyer, for example.

Apple’s iOS has also had a few gaps by comparison, perhaps the most notable being the annoying notification system. That’s due to change when iOS 5 arrives in September, bringing a host of other new features that look appealing as well. If you want a large but lightweight tablet that offers a rock-solid experience and the widest array of applications, the iPad should be at the top of the list. Folks that prefer smaller tablets, need Adobe Flash support or want to customize the experience more by tinkering might consider another option.

iPad Pros: Widest selection of apps, media and accessories; solid user experience; overall stability; great performance.
iPad Cons: Lacking features desirable to some: widgets; unobtrusive notifications; variety of customization options.

BlackBerry PlayBook: Flash monster, but where’s the email?

Research In Motion took a bold step by not using their existing BlackBerry operating system for the PlayBook tablet, but it was the right call. BlackBerry OS hasn’t evolved to effectively compete against newer platforms such as iOS and Android, nor has it offered a solid web-browsing experience by comparison. Instead, the 7-inch PlayBook uses the QNX operating system, which brings many superb features, such as excellent multitasking and solid support for Flash. I also like the fast browser, excellent speakers and the gestures used to navigate the tablet’s interface as well as to wake it up from sleep mode.

Third-party applications have been slow to appear for the PlayBook, so once you get through the basics, the software store shelves get a little bare. This is one of the two most limiting factors to the overall sales success of the PlayBook; the other is how it handles email. The PlayBook shipped without a native email client, leaving me to fend for myself with using mail in the browser. That solution works, but requires constant checking and refreshing of the browser; there’s no way for the tablet to notify me when new email arrives. If you have a compatible BlackBerry handset, however, the PlayBook can use the phone’s email client in a bridge mode.

I personally like the 7-inch form factor of a tablet, so the PlayBook fits the bill for me in that regard. It plays Flash and other videos extremely well, and can do so while other applications are running alongside. But those videos will be limited: You won’t yet find Netflix here, for example. And that points to the software situation, which is limited. Enterprises that are BlackBerry-centric will gain more value from the PlayBook than most consumers will, although a limited number of individuals are enjoying their PlayBook purchase. They’re likely making compromises however: Not minding the necessity of pairing a handset with the tablet for email, and living without a vast array of third-party apps and media options by comparison. If you can deal with the same limitations, the BlackBerry is a portable, powerful performer and will improve when RIM releases the native email client.

PlayBook Pros: Great multitasking, Flash support, good security
PlayBook Cons: Few apps, no native email without a BlackBerry handset

HP TouchPad: a promising starter if you can wait for apps

HP’s TouchPad is the newest of the bunch, but its roots harken back to January 2009. It was then that Palm introduced its new webOS platform and the first smartphone, the Palm Pre, to run it. HP bought Palm for $1.2 billion in April 2010 and retooled the operating system not just for smartphones, but for tablets too. The HP TouchPad is very iPad-like in looks (it uses the same 9.7-inch display), packaging and components, but once powered on, it’s easy to see the different user interface approach webOS takes.

To a large degree, the TouchPad faces the same challenge as RIM’s BlackBerry PlayBook; namely, a small number of third-party applications. So, it’s important that HP has the basics right, and in my usage, I’d say it’s mostly successful. Browsing is excellent, and the email experience is arguably second only to that of Google’s. Multitasking is effective and similar to that on the PlayBook. Other fine touches include Synergy, which bundles contact information from a number of sources and a solid Messaging system that integrates Skype video, Google Talk and other platforms into a single app. The webOS notification system may be the best of the bunch, and a unique sliding pane view of email is handy.

HP has built a very solid tablet framework although performance isn’t yet consistent, as applications can lag at times. The company expects to address that and other open issues with a software update, even as it entices developers to build third-party applications for the TouchPad. The webOS platform shows great promise in this area: It may have the best Facebook app on any tablet, for example. I showed it off in a recent video because it has all the standard Facebook functions but also provides a unique magazine-style view of your Facebook news feed. Among all of the new tablet contenders to the iPad’s reign, I think the TouchPad shows the most promise for these reasons. If you’re willing to take a chance and wait for HP and developers to tune the TouchPad and supporting apps, HP’s new tablet is well worth the look.

TouchPad Pros: Possibly the best multitasking and notifications. Basics are well done. Wireless charging.
TouchPad Cons: Very new, so a work in progress. Few apps, media choices. 

Google Android tablets: too much choice isn’t always good

There isn’t just one Android tablet, which is both good and bad. By allowing hardware manufacturers to use Android how they see fit, consumers have a wide range of tablet choices with sizes ranging from 7 inches to 10.1 inches. Some Android tablets have 3-D cameras, while others don’t; the same can be said of USB ports, memory card slots, and full keyboard docks. But Android tablets from Motorola, Samsung, LG, Acer, Asus and others share one commonality: They all run on Google’s Honeycomb operating system.

Although Honeycomb was the first tablet platform to follow Apple’s iPad, it actually appears to need the most work yet. No matter which Honeycomb tablet I use, I still see stability issues in the form of software crashes or applications that don’t properly scale up. Stability is less of an issue with Android 3.1, but the third-party application situation hasn’t noticeably improved in a meaningful way. For some reason, software developers aren’t rushing to build or port apps for Google tablets. Simply put: Honeycomb felt rushed to me when I first used it in February, and it hasn’t fully matured yet.

It’s not all bad, however. Users of Gmail, Google Talk video calling and Google Maps will find much to like. These services run well on Android tablets — better than on other platforms, where they’re available. This is part of the reason I switched to a Google Android smartphone last year. Google Music shows promise, as does Google Video for movie rentals and purchases. And although not as flashy as competitors, Android’s multitasking is effective.

But more than any other tablets available today, those running Honeycomb appear most like a poor imitation of Apple’s iPad. It’s as if Google is trying to enable all the same features and functions, but falling short in the user experience: a common complaint of Android in general, although I believe the platform has greatly improved over time. I actually prefer the Gingerbread experience — created for smartphones — on my small Galaxy Tab over any of the Honeycomb tablets I’ve used, and I’ve used a few, ranging from the Motorola Xoom to the budget-friendly Acer Iconia Tag A500, plus some in-between.

Early adopters of Android smartphones have seen this before with the platform, and may be apt to ride out the situation as Android tablets improve. But other consumers may be hard-pressed to deal with Android’s current nuances, issues and lack of software. If you like the ability to hack around in Android and don’t mind software crashes, or if you’re a heavy user of Google services and are willing to wait for platform improvements, you have a number of Android tablets to choose from.

Android Pros: Excellent Google service integration; wide range of hardware options and tablet sizes.
Android Cons: Stability isn’t perfect; app selection is lacking; limited but growing number of media services.

The best tablet is the one that meets your needs

As a secondary device, it’s likely most people don’t even need a tablet. Smartphones, netbooks and notebooks can easily suffice for mobile computing needs. But tablets have their strengths too, offering a personal, more immersive touchscreen experience in many situations. Those situations vary, as do all our individual preferences and requirements for a tablet device. That’s why there’s no “best” tablet I can recommend for everyone. Each has something unique to offer, while all of them are likely to improve over time.

Most are made with similar — if not the same — hardware components too, so that places a greater emphasis on the user experience, software and ecosystem. For many consumers, Apple’s iPad brings the total package like no other tablet, as evidenced by sales figures. But the young tablet market offers something for everyone, and that means you can pick and choose which suits you best; something you couldn’t do before this year.

Tiny Capsules Can Heal Worn-Out Batteries

WASHINGTON — A newly created lithium-ion battery that can heal itself may improve the life span and safety of today’s energy-storage technologies, researchers report.

sciencenewsRechargeable lithium-ion batteries power cell phones, laptops and other portable electronics. But, like any batteries, they tend to break down over time.

“There are many different types of degradation that happen, and fixing this degradation could help us make longer-lasting laptop batteries,” said Scott White, a materials engineer at the University of Illinois at Urbana-Champaign who reported the details of the battery Feb. 20 at a meeting of the American Association for the Advancement of Science.

One site of damage is the anode, a battery’s negatively charged terminal. As a Dell Latitude D620 Battery charges and discharges, the anode swells and shrinks. Over time, this cycling causes damage, creating cracks that can interfere with the flow of current and, ultimately, kill the Toshiba PA3534U-1BAS Battery .

To counteract this cracking, White embedded tiny microspheres inside the graphite of an anode. As cracks formed in the anode, they tore open the plastic shells, releasing the contents within: a material called indium gallium arsenide. This liquid metal alloy seeped out of the spheres and filled the cracks in the anode, restoring the flow of electricity.

Damage to a battery — or a short circuit between its components — can cause problems other than a shorter life span. Out-of-control electrical currents have been known to create hot spots that grow into a raging fire.

“It’s not a common occurrence, but when it happens, the consequences are severe,” White said. Battery fires have prompted laptop recalls by Dell and Hewlett-Packard, and the U.S. Department of Transportation has proposed stricter rules for cargo planes that transport large quantities of lithium-ion HP laptop batteries.

To safeguard against this type of failure, White developed a second kind of microsphere made of solid polyethylene, an inexpensive and widely available plastic. A small quantity of these spheres embedded in the anode and other battery components can function as a safety cutoff switch. If the temperature inside the Fujitsu lifebook n6210 battery rises above 105° Celsius, the spheres melt into a thin layer of insulating material that shuts off the flow of electricity, preventing a conflagration.

“We’ve tested this in real batteries,” said White, whose research is funded by the U.S. Department of Energy. “It works beautifully.” This safety feature, he said, could be useful for the electric cars emerging on the market.

“Lithium-ion batteries will continue to be the technology used for the next 10 to 15 years in electric cars,” said Kristin Persson of Lawrence Berkeley National Laboratory in California, who is looking for new battery materials that not only have better energy storage but also avoid some of the pitfalls of traditional batteries. “It will take at least that amount of time to develop new materials.”

Chinese entrepreneur plans to build Southland laptop battery factory

Winston Chung says he believes the region can become a hub for production of electric and battery technology. He recently acquired the Balboa Bay Club and Resort in Newport Beach.

A Chinese entrepreneur who recently acquired the Balboa Bay Club and Resort in Newport Beach said his next venture will be to build a factory in the region to mass-produce batteries that can power a bus for 1,000 miles on one charge.

Winston Chung said he is developing the new lithium-sulfur Acer Aspire 6930 battery plant as part of a broader plan to export products to China.

He has invested in Balqon Corp. in Harbor City, which builds drive systems for electric-powered buses; and is majority owner of MVP RV Inc. in Riverside, which builds trailers and recreational vehicles.

He believes the region can become a hub for production of electric and battery technology.

“In the future you will see … the market for pure electric vehicles and yachts will emerge from Southern California,” Chung told reporters Friday.

He was in town to accept an award from the United Nations Assn. of New York, a nonprofit support group for the U.N., which made him the inaugural recipient of an annual award honoring entrepreneurs who benefit society.

The Hong Kong resident also said he plans to build a Chinese duplicate of the Balboa Bay Club, a sprawling waterfront facility with a 160-room hotel.

Chung’s Seven-One Capital-Business Inc. agreed in August to buy International Bay Clubs Inc., owner of the Balboa Bay Club and the Newport Beach Country Club, for an undisclosed amount.

The 53-year-old Hong Kong resident said he loves Newport Beach and hopes that “little by little I’ll become a resident of the city.” But he wouldn’t discuss rumors that he already has bought a home in the city. “That’s private,” he said.

A HP 484170-001 laptop battery scientist and inventor, Chung made his fortune in the southern China cities of Shenzhen and Zhuhai, where the communist People’s Republic of China created special economic zones in the 1980s to allow capitalist-style businesses to grow.

He donated $10 million to the engineering school at UC Riverside early this year.

Dell announces new Windows 8 lineup for businesses

Dell tabletDell rolled out its new lineup of business-focused Windows 8 computers Wednesday, announcing that it would add two portable Latitude devices and a desktop OptiPlex to its offerings once the new Microsoft operating system is released.

While the announcement provided few technical details, Dell did say that the OptiPlex 9010 is a 23-inch all-in-one desktop, and highlighted its incorporation of touchscreen technology and flexible form factor as its chief selling points. The announcement comes less than 10 days after rival HP announced a set of four new all-in-ones designed for use with Windows 8.

Dell’s new enterprise tablet is a 10-inch Latitude designed, the company said, with security and compatibility in mind. The Latitude 10 features a smartcard reader, fingerprint sensor and floor-to-ceiling encryption, along with cross compatibility with existing management consoles and productivity apps.

Finally, the Latitude 6430u ultrabook is a dedicated road warrior’s machine, packing enough battery power for “all-day productivity,” according to Dell, into a package 16% lighter and 33% thinner than the current-generation 14-inch Latitude notebook. The company also claims that the device is designed to meet the U.S. military’s MIL-STD-810G durability standards, which would make it tougher than the average ultra-portable. (It should be noted that Dell has not claimed that the Latitude 6430u has actually been tested to this standard, however.)

All three devices will be made available when Windows 8 is officially launched, said Dell, adding that information on pricing and regional sales would be released “when available.” Microsoft recently confirmed that Windows 8 would see a general release Oct. 25.
