PEN SPINNING

Pen spinning or pen twirling is a form of object manipulation that involves the deft manipulation of a writing instrument with one's hands. Although it is often considered a form of self-entertainment (usually in a school/office setting), multinational competitions and meetings are sometimes held.^[1] It is a form of contact juggling.

Pen spinning is known as "pen mawashi" (compare for example Mawashi geri, "round-kick") or, more disparagingly, "rōnin mawashi" "college student spinning" in Japan where the pastime has been popular since at least the 1970s, and where the Pen Spinning Association Japan is now dedicated to promoting the aspiring art form. While its origins remain unclear, pen-twirling is quickly gaining international popularity through on-line video sharing and forums. According to Masaki Tsukada, chairman of the Japanese pen spinners, pen spinning now has dedicated movements in South Korea and the United States.

Future Mobile Technology

13 future mobile technologies that will change your life

Disruption 1: Mobile WiMax Sprint Nextel Corp. said it will launch its mobile Xohm WiMax network commercially in a handful of cities next spring with more cities added throughout the year and 2009. It has the potential to be a game-changer, some experts say.
"If you're looking to 2009 or 2010, WiMax will be somewhat revolutionary in terms of wireless broadband," said Brian Clark, a partner with M/C Venture Partners in Boston. "It starts to offer a DSL-level of [wireless] service."
Sprint claims that Xohm's typical (as opposed to peak) speeds will be in the 2Mbit/sec. to 4Mbit/sec. range. And while Sprint hasn't yet provided pricing details, it has said its WiMax offering will be priced similarly to DSL and cable access, which is significantly cheaper than 3G. Even more radically, at least for a company best known as a cellular operator, Sprint won't demand long-term contracts but, rather, will use a subscription model.
Verizon Wireless said it will deploy a competing technology called LTE (long-term evolution), which will have similar speeds to Sprint's Xohm network. However, most observers believe that LTE and similar technologies deployed by other carriers won't start to be available until at least 2011. By that time, proponents claim second-generation mobile WiMax will offer speeds potentially as high as 1Gbit/sec.
Why it's important: Most of the other disruptive technologies discussed here require fast, affordable wireless access.

Disruption 2: Multihop relay networksSome researchers and futurists believe that multihop relay networks will eventually supplant technologies such as WiMax and LTE. With these networks, wireless signals will route themselves through a series of access points. Like the Internet itself, the route that the data takes is variable, depending on conditions.
"The network will find the best route and the best transmission mode," said Wen Tong, director of Nortel Networks' wireless technology laboratory. "I see initial deployment in three years."
A variant of the multihop relay network called ad hoc networks could come even later. With this technology, data would be relayed through, among other things, devices themselves. In other words, your phone will also be a movable access point.
"The defining quality of the ad hoc network is that it has no infrastructure," said Anthony Ephremides, a professor of electrical and computer engineering at the University of Maryland. "I'd guess it'll be [ready] in a five-to-10-year time frame."
Why it's important: These networks will extend network access to where none exists without building a lot of infrastructure. Because there is little infrastructure, the networks can withstand catastrophe. That is why, Ephremides said, the military is sponsoring a lot of research into ad hoc networks.
What could hold it back: This technology is still very much in the research phase, particularly ad hoc networks. A variety of issues, not the least of which is security, have yet to be resolved.
Disruptions 3 and 4: Femtocells and fixed-mobile convergenceBoth these technologies enable you to have one phone and one phone number with which you can communicate from virtually anywhere.
Sprint has started offering femtocells on a trial basis." src="http://www.blogger.com/common/images/site/features/2007/102007/femtocell1.jpg" width=160 height=242>Sprint has started offering femtocells on a trial basis.A femtocell looks a bit like a Wi-Fi router but performs the same function in the home or office as cellular base stations that sit in brick buildings at the base of cell towers. That is, they communicate directly with your cell phone and carry the signal to the larger network via a broadband line such as DSL or cable.
"Carriers will offer femtocells the way cable operators offer cable modems," said Paul Callahan, vice president of business development at femtocell vendor Airvana Inc. "They'll give you five bars in your home."
That means you'll be able to ditch your landline and use your cell phone everywhere. Sprint is offering femtocells, on a trial basis, to customers in Denver and Indianapolis and is charging $15 a month for individuals or $30 for a family. Subscribers can then make as many local and national calls as they want.

T-Mobile USA launched its http://www.computerworld.com/action/article.do?command=viewArticleBasic&articleId=9025820 program last June, which requires a cell phone that supports both Wi-Fi and regular cellular access. Built into the phone is software that enables you, for example, to walk into your home or office while talking on the cellular network and have the call seamlessly switch to voice-over-IP on the Wi-Fi network. You also need a compliant Wi-Fi router.
As with femtocells, fixed-mobile convergence allows you to lose your landline. T-Mobile is charging about $30 a month for unlimited local and national calls. The program has met with generally good reviews.
Why it's important: Having a single phone and a single phone number will be a great convenience and money saver. Also, some of the disruptive applications discussed later depend on the ability to track your availability no matter where you are. Using only a cell phone makes this more possible.
What could hold it back: To some extent, these technologies will duke it out against each other. That will take time to sort out.
Better devices
With faster, more ubiquitous access, devices can start to radically change.
"Imagine a Bluetooth headset in your ear but that's the phone," said Dan Burrus, CEO of Burrus Research Inc. and author of the book Technotrends. "And it will continue to get smaller from there until it's implanted in your ear. You ask for whatever you need [with your voice] and it will tell you the answers."
However, smaller, more powerful phones themselves will be the end result of several enabling disruptions, Burrus and the other experts agree. These disruptions may seem relatively minor but, added together, they will result in the phones and applications of tomorrow.
Disruption 5: Miniscule, less power-hungry mobile chipsChip vendors have been talking about smaller, more powerful and less power-hungry chips for a long time. Now, development of such chips is likely to accelerate.
"Companies like Intel have focused on putting more transistors on a chip and making their products more powerful," said Anthony Townsend, research director at Institute for the Future. "It takes a while to turn a ship like that around." The rapid growth of all things mobile is accelerating that trend, Townsend said.
Besides being smaller and significantly more power efficient, tomorrow's mobile chip sets will also combine multiple radios, such as Wi-Fi, 3G and WiMax, on a single chip, according to the experts.
Why it's important: Smaller, more powerful chips mean smaller, more powerful mobile devices and applications. Combined with faster, ubiquitous wireless broadband, that means devices can be sewn into clothing, placed unobtrusively into ears or even implanted in your teeth.

Disruption 6: Wireless USB and ultrawidebandThese short-range, wireless cable replacement technologies are starting to be available. Admittedly, they lack the gee-whiz factor, but they eventually will make life much easier for mobile users.
Why it's important: At the very least, it will be nice to synchronize data between devices and desktops wirelessly. Short-range wireless cord replacements will also be useful for entertainment applications such as streaming video throughout the home. But the real benefit will be using these technologies with tiny mobile devices, according to Derek Kerton, principal of the Kerton Group, a telecommunications consulting firm.
"If we get miniscule phones, they could use wireless USB or UWB to connect to a full-sized keyboard," Kerton said. "Or we could have tiny devices that [use these technologies to] project usable keyboards on desks or images on walls."
What could hold it back: Not much. These technologies are already well established and should become widely used in the next couple of years.
Disruption 7: Nearly flawless speech recognition
Another mobile input application on the horizon is better speech recognition, which will be enabled by more powerful mobile chips.
"Speech recognition got bogged down because it was only 98% or 99% accurate," Burrus said. "Even at that accuracy, many of us found it was faster to type. A lot of the problem had to do with processing power -- speech recognition needs a lot of horsepower."
More powerful mobile processors will solve that problem, Burrus predicted. And speech playback will become more natural-sounding, he added. In other words, everything you do with your keyboard at your desk, you'll be able to do with speech while you're mobile.
Why it's important: If you have a teensy mobile device that is, say, tucked in your ear, better speech recognition and playback means you don't need a keyboard or display. You'll be able to perform complex functions such as Web searches or buying things using your voice.
What could hold it back: Users could be reticent about letting others in public places hear their business. They may prefer to combine better speech recognition with other methods of input.
Disruption 8: Foldable displays and e-paper
Vendors such as Philips and Fujitsu Computer Systems Corp. have been publicly showing foldable and e-paper displays for mobile devices. Both will enable tiny devices to display data clearly on easily stowed screens.
E-paper uses a mylar-like screen, said Paul Moore, senior director of mobile product marketing at Fujitsu.
Fujitsu Computer Systems is showing e-paper for mobile devices and other uses." src="http://www.blogger.com/common/images/site/features/2007/102007/e_paper.jpg" width=160 height=135>Fujitsu Computer Systems is showing e-paper for mobile devices and other uses."You can maintain the image with no power at all," he said. "So I take a small tube [of e-paper] out of my pocket, unfold it and there's the New York Times. I can use the same e-paper for tomorrow's paper."
E-paper will have a dramatic effect on laptops, Moore predicted. That's because, when it is improved enough that it can support constantly changing images and not just static ones, it can replace laptop LCDs. That will dramatically cut both laptop weight and power consumption, Moore said.
In addition, Japan's NTT DoCoMo is experimenting with e-paper to replace keys and icons on phones. With e-paper, those keys and icons can change as you change applications from, say, being in voice mode to being in media playback mode.
Why it's important: Foldable screens and e-paper mean we can easily have big displays with our miniscule mobile devices.
What could hold it back: The technology still must be perfected. Also unknown is how much such displays will cost.
Disruption 9: Centralized storage
Fast, ubiquitous wireless access will enable centralized storage on remote servers, which will have a series of important ripple effects, according to Burrus.
"You don't need a lot of bulk [on a device] if you offload storage and other functions to a [centralized] server," Burrus said.
Kerton agrees. "How much sense does it make to store a specific jazz album on your device and everybody else is storing it on their device, too?" Kerton asked. "We're doing massive edge storage and that doesn't make sense."
Why it's important: After faster, more powerful but smaller mobile chips, ubiquitous wireless connections and better input-output methods, centralized storage is the final step toward completely untethering mobile devices and those of us who use them.
What could hold it back: So far, Internet-based storage has not proved popular. It's hard to break old habits of local storage.
Better applications
So what do we do with these powerful, tiny, highly connected devices with satisfying input and output? The answer, of course, is new, innovative applications.
We can't hope to cover all the potentially disruptive applications of the future, but we can describe why a few will change your life. We'd love to hear your choices in the comments section of this story.
Disruption 10: Unified communications
Huge technology players such as Microsoft Corp. and Cisco Systems Inc. are pushing for the ability to tie together all forms of communications, including landlines and the various types of wireless. It's a compelling vision that is a stew comprised of many ingredients.
One futuristic ingredient in unified communications is sometimes called "superpresence," which is like a supercharged version of the instant messaging feature that lets you know if a buddy is online. In this case, superpresence could also provide information such as the best method at any given moment to communicate with a person or an estimate of when that they'll arrive at a destination. Users will create rules that say, for example, they can be interrupted by a spouse and boss, but not by others.
Another part of this stew includes technologies already mentioned, such as fixed-mobile convergence and femtocells, because they make it easier to locate and communicate with people Two more ingredients are the ability to transparently route communications to an individual via disparate networks and the ability to share applications in real time via those disparate networks.
Why it's important: One word describes why this is important: productivity. For instance, far-flung project teams will be much more efficient interacting with each other and exchanging ideas and other mission-critical information.
What could hold it back: At some point, employees may tire of being available 24/7, and unified communications will make it even harder than is currently the case to escape from work.

Disruption 11: Mobile commerce In Japan, cell phone users are increasingly using built-in near-field communications technology to swipe their phones near special point-of-sale terminals to buy things.

Disruption 11: Mobile commerce
In Japan, cell phone users are increasingly using built-in near-field communications technology to swipe their phones near special point-of-sale terminals to buy things.

Proponents claim this technology has other functions. For instance, you'll swipe your phone near a concert poster to download more information about the performer and to buy tickets. Or swipe your phone near an in-store kiosk to get digital cents-off coupons.
Why it's important: Utter simplicity. No more fumbling around for your credit card or struggling to keep track of your purchases. And you can easily share the information with your desktop financial manager.
What could hold it back: Cellular operators, phone vendors and credit card companies are keen to get this off the ground. However, it would require merchants to buy new point-of-sale terminals, which could be a hard sell.
Disruption 12: Mobile security
Of course, security is needed for mobile commerce and many other next-generation applications. Burrus said not only will future phones be secure, but they'll be used in other contexts to ensure security.
"We'll have new levels of biometrics," he noted. "If your phone is in your ear, everybody's inner ear canal is different and the phone can tell. That's one form of biometrics. Similarly, everybody's voice is different. Or maybe the phone will discern blood vessel patterns in my ear." Then, there's fingerprint scanning, already common with laptops. Best of all, this security could be performed automatically, making secure transactions easier and faster.
Why it's important: Besides protecting your transactions and data, you'll be able to use your mobile devices to gain admittance to secure areas at work or maybe even at the airport.
What could hold it back: Advanced biometrics will be attractive to corporations, but it surely will add to the price of devices, which could lead to resistance, at least among consumers.

Disruption 13: Augmented reality
Imagine looking at something in the real world -- say a building -- through your mobile device, then putting a virtual overlay over it. Sounds like a game, but it potentially has some very real-world applications, according to Townsend.
"It will help anything that can benefit from simulation," he said. "An architect working at a construction site, or a firefighter finding a way out of a burning building or a UPS driver visualizing the next 10 steps of his delivery route." Another possibility: A surgeon performing a complicated procedure.
Why it's important: Augmented reality can help us understand the unknown in real time. That will lead to greater safety, more flexibility and better health care.
What could hold it back: This still remains the subject of a lot of research before it becomes practical and affordable.

Blog #2

Question #1:
What is your favorite wireless device? Why is this significant to you?
Answer:
My favorite wireless device is my cellphone. Because of my cellphone I am more updated on news and information about my family,relatives and friends. We can easily communicate with each other. Some features of my cellphone provides me entertainment such as musics,games and videos. I can also use it to take photos and videos of my friends and relatives. With this device, my social life is more happier.

Question #2:
Imagine a world where there are no wireless devices.What are the significant implications of this scenario?
Answer:
Our world will experience not much advancement in science and technology without wireless devices. People will still be experiencing difficulties trying to communicate with each other. Obtaining information on researches will be hard to derived. Hence, what we are enjoying now a days due to having wireless devices such as cellphones, laptop, bluetooth devices helped improved our work, lifestyle and even social relationship with others. Specially, most of the Filipino are now working abroad more and more members of the family are being physically separated with each other, nonetheless, because of wireless devices it makes the family ties more stronger.

Field Trip

I choose this picture because I never see a white tiger before.A white tiger is a tiger with a recessive gene that creates the pale coloration. Another genetic characteristic makes the stripes of the tiger very pale; white tigers of this type are called snow-white or "pure white". White tigers are not albinos and do not constitute a separate subspecies of their own and can breed with orange ones, although (approx.) half of the resulting offspring will be heterozygous for the recessive white gene, and their fur will be orange. The only exception would be if the orange parent was itself already a heterozygous tiger, which would give each cub a 50% chance of being either double-recessive white or heterozygous orange. If two heterozygous tigers, or heterozygotes, breed on average 25% of their offspring will be white, 50% will be heterozygous orange (white gene carriers) and 25% will be homozygous orange, with no white genes. In the 1970s a pair of heterozygous orange tigers named Sashi and Ravi produced 13 cubs in Alipore Zoo, of which 3 were white. If two white tigers breed, 100% of their cubs will be homozygous white tigers. A tiger which is homozygous for the white gene may also be heterozygous or homozygous for many different genes. The question of whether a tiger is heterozygous (a heterozygote) or homozygous (a homozygote) depends on the context of which gene is being discussed. Inbreeding promotes homozygosity and has been used as a strategy to produce white tigers.
