You are off out for the evening. Everybody is waiting for you. Your mobile is essential; there is no way you can leave home without it. How would you meet up with everybody or order that taxi? You might miss an important text or email message and you need to check a few things on-line. This is the modern age. We can no longer afford to be distanced from our mobile phones.
You check it and the battery is nearly flat. You check your spare battery. It is flat also. Now what do you do? It will take at least 30 minutes to get sufficient charge to last the evening. You should have checked earlier.
This will soon be a scenario from the past. In the future you will plug your mobile phone into the charger and 10 seconds later it will be fully charged. How can that be?
The answer concerns that new buzzword nanotechnology. Your phone will currently be using what is called a lithium ion battery. They are great batteries to use because they are very light and will hold a lot of charge. The problem is that they can only be charged quite slowly. The reason for this is that all those lithium ions that have been made while releasing electrons to power your phone have to be converted back to their original state and this takes quite a time.
Now a new type of lithium ion battery has been invented that uses nanotechnology. The battery cathode (that’s the negative end) is made of nano-sized balls of a chemical called lithium iron phosphate coated in another chemical called lithium phosphate. These balls are only 50 nanometres in diameter, which is just about the size of a virus. It turns out that these nanospheres are super efficient at absorbing the lithium ions during the battery recharging cycle. The inventors who work at the Massachusetts Institute of Technology believe that if they made a phone battery out of this it would charge in ten seconds.
They still have a few little problems to iron out but it is probably not that far away.

Broadcast Your Dream Wedding
These days many couples are whisking away to some pretty exotic places to say “I Do” Then there are those who don’t want to go exotic but still want to have their weeding in a beautifully romantic place, such as the Wedding Pavilion at the Grand Floridian Resort, Walt Disney World. While this sounds great to the excited couple, it may not be so exciting for those friends and family members who cannot join them.
Destination weddings have exploded to include a little over 15 percent of all weddings—quadrupling in under a decade. However, the problem of disgruntled guests and ultimately, empty seats, has remained steady.
Live video streaming services is now the answer to the problem of absent guests at the couple’s dream wedding by providing an inexpensive, uncomplicated technological solution. Now, live video streaming services can capture the wedding, during and after the actual ceremony.
When planning a wedding, the bride and groom of course get caught up in what they want. They have grandiose dreams what their perfect wedding should be like and where it should be held. Then, reality sets in. Suddenly brides and grooms realize that many invited guests cannot make it to the wedding due to travel costs, health concerns or conflicts. The number one reason many guests cannot attend is the high cost of travel. It doesn’t stop there though. Travel is not only expensive but if also requires many people to request time off of work, which becomes an issue as well. This huge realization ca often cause the couple to feel guilty for indulging in their dream wedding being held in a non-traditional location.
In today’s age of growing technology, it is now possible to broadcast the event live so those who are unable to attend can still be there, in a way. Keeping the technology simple, live video streaming services can be used worldwide and by both professionals and amateur videographers.
Those guests who cannot make the live event can receive information explaining the login protocol and reminding them of the date and time. If the guest forgets to watch in real time, the video is available for download moments after the nuptials are made.
With live video streaming services; there is no need for the bride and groom to feel guilty about the location they choose for their wedding. They can still have their dream wedding in any location they choose and be assured all guests will be able to experience the event.

Anti-spyware Software
Computer programs that are used to find computer viruses are called antivirus software. There are various types of attacks faced by computer users. Some of the more common viruses are worms, root kits, trojans, malware, etc. Modern antivirus software provides security from these viruses.
After the introduction and growth of the Internet, these viruses found a way to spread quickly. There are many methods used by antivirus software to detect the attacks. Some of them are signature based detection, malicious activity detection, suspicious behaviour monitoring, heuristics analysis, etc.
Behind this software there are some other ways to provide security for computers and their data. One of them is by using network firewalls. These firewalls are used to prevent unknown programs and the internet processes from having access to the computer system. Unlike the antivirus software, it is used to protect a LAN from the Internet or other LANs. The system virtualization can also be made to prevent the computers from virus infection. Anti-spyware software programs are used to remove the spyware and prevent the unauthorized user’s interaction with a computer. Many commercial firms released their products to remove or block spywares.
Nowadays, the antivirus programs also prevent the features of anti-spyware. The separate anti-spyware gives us real time protection against the spyware software, provides an easy interface to use, scans the contents of operating system files, windows registry, installed programs, etc. Some of the programs that are used to automatically play, display or download advertisements to a computer are known as adware. Some of the types of adware are actually spyware. There are also programs that are used to block typical adware from infecting the computer system.
Antivirus software should be updated periodically so that it may check for any recent attacks. There are also many types of software available separately for internet security. Some of the web browsers are more secure from attacks than others.

Article Street » Technology » DVI Cables: Are you confused? Hosted By: Unlimited Hosting DVI Cables: Are you confused? German Spanish French Italian
When you look at your various DVI connectors it can be quite confusing. For instance if you look at the plugs and the sockets they can appear very different. We would normally expect a plug to have the same number of pins as the socket has holes; it is what we are used to. But with a dvi cable it is entirely different. Some connectors have sixteen sockets arranged in groups of 4, 8 and 4 with a little slit between one of the 4 groups, some have 21 holes and a slit, and some have 18 holes and a slit.
The reason for this variety is that when the DVI standard was implemented it was decided that is must be possible for the same cables to transmit both digital and analogue signals. In order to achieve this, a variety of interfaces were developed. These are:
* DVI-A. This interface only transmits analogue signals, there are no digital connections.
* DVI-I. The DVI-I interface will transmit a combination of digital and analogue data.
* DVI-D. This is only for digital data.
The designs are as they are because it was decided that the DVI interface would be compatible with a VGA interface (for instance if you had a VGA connector on one end of the cable and a DVI connector on the other end only analogue signals would be transmitted). By supporting both the analogue and digital signals it means that the user can plug the display into the computer and it will work whether it is analogue or digital. This system was introduced as it was realised that there would be a gradual transition between DVI and AVG and this system would make the transition much smoother.
Depending on the mixture of your equipment there is a variety of DVI cables to choose between. For instance if you have a DVI output on your computer and a VGA connection on your CRT monitor then you will need a DVI to VGA monitor cable. Alternatively you may need a DVI-I analogue and digital monitor cable, or a DVI-D single or duel link monitor cable.

Solar Power for Office Buildings
If you drive through a big city you will realize that office buildings are being built all the time. This gives people a place to work, and for many, a great way to make money. That being said, the office buildings of today are not the same as older ones. One of the many upgrades that you may notice is solar power panels on the roof. This is becoming more popular in modern office buildings, and the trend is sure to continue as it is proven to be effective.
Of course, building an office building with solar power is much more expensive than a more traditional setup. That being said, builders are not interested in traditional any longer. They know that companies are interested in going green, and this is why solar power is going to continue to be a major component of many new office buildings.
Even though it is easier to add solar power during the building process, it is possible to add panels at a later date as well. This can be costly upfront, but in the long run it will pay off big time.
There is no denying that solar power for office buildings is beneficial. Those who use office buildings suck up a lot of power on a daily basis. By using solar panels these buildings and the companies that use them can become much more efficient. This is a great way to give back, and to save a lot of money both now and into the future.

Article Street » Technology » Which smartphones should you want to buy in 2009? Hosted By: Unlimited Hosting Which smartphones should you want to buy
Smartphones have always been big business, but this year, they're set to get even bigger, and a selection of new phones in 2009 look set to make them all the more important: the Nokia N97, the Toshiba TG01, and the astounding Palm Pre.
Nokia N97 - a touch of Symbian
If we're discussing smartphone software, Symbian has always been one of the big names in the market, and the most up-to-date, touch-based version continues that upstanding tradition, in the body of the Nokia N97. You don't just get a touchscreen, though, since the Nokia N97 has also got a full QWERTY keyboard, that makes texting, live chat and emails so easy to do on the move. As for what else it can do, the Nokia N97 will also impress with its 5 MP camera, awesome multimedia player (which includes video playback that simply has to be seen to be truly appreciated), a huge 32Gb of storage space, and super-fast web access. Basically, the Nokia N97 is amongst the best phones in existence.
Toshiba TG01 - Windows, but nice
Whilst Symbian has been evolving competitors Microsoft haven't been resting on their laurels, and the new phone to show off Windows Mobile is the super-powerful Toshiba TG01. It doesn't just have the biggest screen ever found on a mobile phone, weighing in at 4.1 inches, but the Toshiba TG01 also has the most powerful processor ever used in a mobile phone. Dubbed Snapdragon, the 1GHz, multi-core chipset gives the Toshiba TG01 raw power, and since that's what's needed to let Windows Mobile run at its optimum level, the Toshiba TG01 is arguably the best WinMo phone that's ever been announced.
Palm Pre - the new hotness
However, there's a new kind on the block, which wants to take the smartphone crown all for itself. The Nokia N97 and the Toshiba TG01 both both have raw power, but what the new Palm Pre goes for is sheer elegance. With the brand new, unprecedented 'WebOS' powering it, the Palm Pre brings touch-friendly interactions and innovative design to a whole new level. For example, consider the new Fandango software which should be available when the Palm Pre is launched. It's an online cinema booking app, which lets you purchase tickets and watch trailers on your phone. However, even the Nokia N97 will most likely be able to do that. The Palm Pre, however, can also automatically add a note in your calendar, and contact people who are going with you, to let them know when and where. It's that kind of integration, and interplay between features that makes the Palm Pre the best candidate for phone of the year.

LCD Screens Transforming Digital Signage and Advertising in Restaurants and Retail Stores
It is not hard to understand why LCD displays screens are rapidly being adopted by retail stores and restaurants. InfoTrends conducted a digital signage study where they polled consumers and found that "digital signage displays have a 47.7% effectiveness on brand awareness, increase the average purchase amount by 29.5%, create a 31.8% upswing in overall sales volumes, generate a 32.8% growth in repeat buyers and generate 32.8% more in-store traffic". LCD display screens are being used by restaurants for displaying the menu and entertainment, by garment and clothing retail stores to show videos of fashion shows and to showcase various products, and by automobile dealers as video walls to provide the feel of the car on the road and to keep the customer occupied as they wait for sales agent or other people.
LCD Display Usage in Restaurants: When visiting KFC Hyderabad (India), what grabs your attention is not so much the smell of food but the vibrant colours of the four 42-inch LCD display panels which serves as the overhead menu board. KFC Hyderabad sought the help of Sharp Business Systems India (http://www.sbsil.com) to set up the digital signage solution. LCD digital menus can be maintained from a remote central location or a local PC set up in the store. The benefit of remote central management is that menu, promotions, video, pricing and other items displayed on the LCD displays in the retail outlet can be managed from one central location to provide consistency and to make sure that the changes are made consistently across all stores at the same time. Consumers receive dynamic previews of the offering with potential for positive impact on sales. If restaurants have the networked point-of-sale cash registers collecting time based purchased data, marketing can get instantaneous feedback on how different promotions and pricing are having impact on sales. Restaurants are also using LCD displays as televisions to spruce up the restaurant atmosphere. It is now a common expectation to have LCD TVs in restaurants that show the local sports or the news.
LCD Display Usage in Showrooms: Whether it is women clothing store, automobile showroom, convenient store or a department store, LCD displays are appearing in all these locations. A typical store has up to four LCD displays per site. InfoTrends study showed that business that had installed displays in their showroom, predominantly expected the display usage in their showrooms to increase. To grab and hold consumer attention, retailers are using LCD displays in a video-wall format or in a daisy chain format along with stand alone units. The content could be a mixture of video along with text or a combination. The goal is to target specific customers with specific information and this information may change with the time of the day - creating a retail company-owned, closed-circuit television network that runs nothing but the retail company programming.
Why do Retail Businesses Select LCD Displays vs. Plasma Displays? There are a number of reasons why retailers and restaurants are selecting LCD display over plasma displays.
· Fan-less Architecture of LCDs: LCD displays do not have a fan potentially resulting in less noise and distraction. This is less of an issue with newer higher end plasma displays, however it is worthwhile to keep track as you evaluate the two options.
· Rugged Design of LCDs: LCD displays are closed-box units and more rugged. There is less chance of oil fumes, dust or other elements getting into the unit and reducing the life of the unit.
· Resolution and Picture Quality: (A) Video resolution on LCD displays and plasma display are comparable but computer data is better observed on LCD displays. (B) LCDs are better to view in ambient light or in brightly lit rooms. As businesses usually work during the day in ambient light, LCDs are more desirable for most business applications. (C) Plasma manufacturers have made much of their viewing angles. However with new LCDs the view angles are 176°. There is not much difference between the two technologies in viewing angle. (D) There have been concerns with burn-in for Plasma screens especially for static images. However, many Plasma manufacturers have improved their anti-burn in technology. There are no burn-in issues with LCD screens.
· Life of the Display Unit: LCDs can be operated 24x7 for 50,000+ hours equivalent to 5+ years of continuous viewing. Plasma, on the other hand, typically has a half life of 30,000 hours. At half life, the phosphors in a plasma screen will glow half as brightly as they did when the set was new. There is no way to replace these gases; the display simply continues to become dimmer with use. An LCD TV will last as long as its backlight - and in many models the backlight bulbs can be easily replaced!
· Power Consumption: Plasma TVs use more power than LCD - twice as much Technology for both plasma and LCD display continues to change. Be sure to check updates to the technology for apple to apple comparison

Laser TV Versus OLED TV – Which Technology Wins?
Laser TV - What Is It?
There is much hype around this type of TV, yet the technology has been around for a number of years. The term Laser TV refers to the principle of literally firing a laser onto the inside of a TV screen in order to produce an excellent quality image. This process is more efficient in producing an image compared to our current plasma and LCD TVs. When you consider the range of colors that are visible to the a human eye (known as color gamut), plasma and LCD can only manage to produce 40% of these colors, whereas laser TV technology can produce an excellent 90%.
The Technology Behind Laser TV
Lets take a simple look at the principle behind the technology, to truly understand how it works.
Current TV technology produces red, green and blue light (RGB). In principle it is possible to combine these three colors to produce a complete full range of visible colors, however in reality, visual displays are only capable of displaying a limited range of these colors. However, in a Laser TV, three distinct wavelengths are used, these are simply light beams which project accurately and brightly onto the screen, producing brilliant blacks.
The whole technology is based around the principle of projection, with this in mind Laser TVs are a perfect improvement on our current rear projection TVs, these are TVs whose images are projected from the rear of the TV on to the back of the screen. A typical rear projection display tends to measure from 50 inchs to 100 inches and are regularly used in public spaces. It is the ultra High Performance Lamp (UHP) which is the basis for the technology, however laser technology essentially replaces this and as a result very much suits the larger screen size.
What Laser TVs Are Available To Buy?
Mitsubishi became the first manufacturer ever to make a commercial Laser TV available to consumers in stores in November 2008. Aptly named Laservue, this TV was priced at around $7,000. A little pricey for today's market. The Laservue is available in 65 inch or 73 inch versions and is also 3D ready and as you would expect these days it is perfect for wall mounting.
Rumors of Toshiba entering the market are spreading rapidly. Whether many other manufacturers wish to enter the race remains to be seen.
LASER TV vs. OLED - How They Stack Up?
To be honest, as the two technologies stand at the moment, Laser TV is suited to one end of the TV market and OLED the other. Laser TV technology currently suits the large display market and at present OLED technology suits the smaller display market, of course this will change as both develop over time. The two technologies are not yet going head to head in the TV market.
Take a look at the features of each:
LASER TV:
- Wider range of colors displayed (roughly doubling standard HDTV's)
- The intensity of the laser is maintained for the lifespan of the TV, meaning a high
quality image is maintained throughout the life of the TV, unlike current HDTV
technology
- Laser TVs utilize roughly a quarter of power used by current TV technology
- Laser TVs tend to be half the weight of current HDTV's
- First TV commercially available in 65 and 73 inch versions
OLED TV:
- Excellent image quality at 1000000:1 contrast ratio
- Better image quality means wider viewing angle of 180 degrees
- Ultra thin screens measuring 3mm thin
- Power consumption is less that current technology since no backlight is required
- First TV commercially available in 11inchs
So What Are The Disadvantages?
There always seems to be a worry around any laser technology, scare mongers will raise issues around potential eye damage from a laser should a Laser TV become damaged. These concerns are yet to be proven. However it is suggested that special filters can be fitted within the TV to remove this potential fret.
Another concern is the speckle effect. Laser TV technology can produce an effect on the human eye which resembles speckling, this is caused by a number of waves joining together to produce a wave with varying intensity. This issue is being addressed by manufacturers, expect this to be overcome in near future.
Which Technology Wins? - Laser Or OLED
Laser TVs are on sale now and available to all....well to most, if your bank balance can support it and your home is large enough. If this suits your circumstance then laser TV is a possibility for you at this time. OLED TV is cheaper by comparison, but not at the prices the average consumer would be happy with and screen sizes do not reflect what we have become used to for our homes.
As yet, laser technology has a way to develop, as more manufacturers take up the challenge. Prices should decrease and so will screen sizes. Likewise OLED screen sizes are set to increase. There does seem to be more of a buzz and excitement in the industry around OLED. Image wise these two technologies are truly head and shoulders above the rest and once these TVs truly develop and become TVs we can afford and want in our homes then there could be more of a head to head battle.
Which technology is better you ask? Considering all other factors, at this stage, it is just too early to tell.

ELECTRIC BIKER
Pedal-Assisted Pleasure...
Stepping outside my island hideout, I hoist the bamboo-stiffened tarp like a gaff-rigged mainsail and cleat it off to the side of the shed. In the soft interior light, the bike's clear plastic fairing throws off reflections with the promise of motorized adventure only two wheels can offer.
The machine waits, eager and enticing, as I pull on helmet, goggles and gloves and zip my armored jacket to the chin. The charger's pulsing green light says, "Go!"
Unplugging the BikeE, I wheel it out under last winter's ravaged apple tree, swing my leg over its low-slanting frame, and settle back in the semi-reclining seat with a sigh of coming home. A quick brake check and final adjustment of the handlebar mirror gives me a moment to focus and quiet the adrenaline surging through me like the voltage I'm about to feed my pony.
Reaching down, I punch the big red button on the heavy duty controller bolted to the side of the bike's box frame. A red glow reflecting on my glove is the only indication that we have ignition.
I touch the thumb throttle and any doubt disappears in a surge of torque.
As Honda Chairman Takeo Fukui reminds us, "Even the best internal-combustion engines still waste more than 80% of the energy created by burning gasoline."
But electric hub motors can deliver full power directly to the wheel. And if that rotating motivator happens to be just 16-inches in diameter and connected to the front of a low-slung bicycle, you'd better be ready to brace for the kind of acceleration that brings big grins to the faces of all those who believe that fast is good.
And faster is better.
Shouting, "Power to the people!" I tuck my feet into the Power Grip straps as the bike moves forward under its own power and each pedal rotates into position. Making for the cove's paved two-lane road, I swing out of the gravel driveway that earlier last summer judo-flipped me into a 10-week aching meditation on paying attention. (Nothing broken and not a scratch on the bike - and no bruises if I'd been wearing the padded mountain bike jacket I always wear now.) Downshifting the internal rear hub transmission, I keep peddling in laid-back comfort for the long climb out of the "gravity well" leading up the relentlessly steep and scenic hill from Ford Cove.
Passing Olson's farm, the grade inclines. Tilting back in the seat like a light plane pilot on a long climb-out, I keep peddling easily while gradually coming in with full power. Despite the drastically steepening grade, speed continues to hover around 22 kph as the numbers denoting amperage draw tick over quickly on the Cycle Analyst meter: 8, 10, 14, 20… 29 amps!
Don't try this on a hot summer day without at least a 36-volt motor/battery combo, heavy-duty fuse clip and overbuilt power controller!
But this classic, power-assisted BikeE handles the load without strain. Even at full power, the whine of the motor is much quieter than the bird cries and soft wash of distant surf. Lulled by the hum of the bike's spinning tires, I lay back in my lawn chair and admire the ocean view as the hill that used to necessitate three panting stops to recharge my "preemie" lungs tops out in trees, sunshine and smiles.
Starting down the backside, I firm my grip on the handlebars as the bike tips straight down in one long burn of all this "heightened" energy. Weighing over 225 pounds with rider, battery, controller and motor onboard, the BikeE sucks up gravity like rocket juice, accelerating like a Saturn IV leaving the pad.
In seconds, the speedo whisks past 40 k.
Whack! A bug bounces off my newly acquired ski-goggles. Good purchase!
Even with power all the way off, at 45 kilometers-per-hour, "organic" regen kicks in as the spinning front hub motor maxes out and begins pumping juice back into the battery. Our descending rush does not slow as 13 amps momentarily surge back into the 36-volt sausage of wired-together Nickel-Metal Hydride laptop batteries cinched to the bike's boxbeam frame in front of the seat.
Nearly supersonic, I "think" the bike's little front wheel past a jagged pothole. Even though you can't fly over the handlebars in a recumbent crash, a front tire blow-out at 57 k would not be fun. Which is why that Kenda Qwest high-pressure tire is new, internally protected with slime and a Kevlar puncture barrier - and regularly replaced.
Speed slackens gradually as the BikeE levels out, but it's still another few moments before peddling again takes effect. Downshifting once, twice, three-times on the seven-speed rear sprocket, I thumb the power back in to keep grunt work off the pedals as the next hill looms. One more swooping roller-coaster is followed by a long pleasant flat stretch that finds me lightly blipping the throttle in a "pulse and glide" technique that extends range while keeping peddling speed near a brisk 30 k.
Onboard a conventional bike, I'd be staring down at the pavement, back bent, with my weight on my aching wrists. But unlike full recumbents, which put riders almost on their backs, the BikeE's more upright seating gives me good eye contact with the astonished driver of a passing car - as well as fine views of unscrolling woods, sky and farms. I once passed Hogan trotting his horse along this stretch, proving conclusively the "one horsepower-plus" rating of my 480-watt Crystallite e-motor.
Then comes another long delightful downhill run past a fine sweep of ocean rolling into Little Tribune Bay. Even leveling off, this descent carries me in a rush all the way to the Co-Op bike rack.
Who says a grocery run has to be boring?
Or must burn carbon?
The bike's big wire basket, Spiderman totepack, and extra-long frame allow me to carry more than 30 pounds of cargo with ease. (I've even hauled logs lashed to the frame.) A trailer would turn this bike into a pickup truck, while carrying an extra battery for nearly 100 km range!
So far, so good. The reliability of this rig is nearly 100% after I learned to obsessively tape, wire-tie and check every looping strand of wire clear of spinning sprockets and pedals. Over less than a year, the 1,800 or so kilometers I've covered on my electrified BikeE translate into roughly 40 gallons of gasoline saved - or more than 800 pounds of CO2 kept out of the atmosphere forever. Except for my own exhalations of course. Which I tend to do anyway.
Mental and physical health benefits are incalculable. Not to mention the additional personal liberation of saving a fortune on the car I no longer support. At 59 - on my electric bike - life is good!
No one ever told me the end of the world (as we've known it) would be so much fun.
