Sony super-flexible OLED screen

//-->

The miniaturization of electronic components has seen mobile devices shrink to the point where screen size is a major limiting factor. That could be set to change with Sony announcing it has developed a super-flexible full color OLED display which can be repeatedly wrapped around a thin cylinder while still producing moving images. Could we soon see mobile phones with pencil form factors and roll out displays?

The new display was possible thanks to the development of integration technologies of Organic Thin-Film Transistors (OTFTs) and OLEDs on an ultra-thin 20-micrometer thick flexible substrate. A flexible on-panel gate-driver circuit with OTFTs and soft organic insulators allowed Sony to get rid of the conventional rigid driver integrated circuit (IC) chips that would impede the rolling up of a display.

Green Technology: solar charger for mobile devices

//-->

 Canada's Kiwi Choice has announced the release of a strangely familiar-looking portable solar charger for mobile devices. The three-panel photovoltaic fan design first used by Solio has found its way to Kiwi's U-Powered charger. Featuring a powerful battery, LED flashlight and magnetic feet, the product also comes with multiple device connector tips for maximum compatibility.

The U-Powered solar charger is the first of four green products to be announced by Kiwi Choice. As well as being a backup power source or outright charger for portable electronics such as smartphones, cameras and media players, the device also offers the versatility of not being wholly dependent on the sun for its power. When sunlight adamantly refuses to appear or when users just need a quick power boost, the unit can be hooked up to just about any power source via USB, car or wall charger.

EVDO

//-->

EVDO is the abbreviation for Evolution-Data Optimised or Evolution-Data Only. It is the new emerging standard for wireless transmission of data via radio signals. This technology is presently used for wireless broadband access of the internet. In the ever advancing telecommunications technology, EVDO has arrived using the multiplexing techniques such as CDMA or Code-Dvision Multiple Access and TDMA or Time-Division Multiple Access in order to enhance and maximise the thoroughput of the individual user and the overall system. EVDO rides on the CDMA network, much like the cellphones.

This 3G wireless broadband internet access service called EVDO is directly competing with Wi-Fi. While Wi-Fi has limitations, EVDO transcends most of this and provides always-on internet services. Wherever your cellphone has range, EVDO will function and provide high-speed internet. The US has seen a spurt in the EVDO service providers with the emergence of Verizon and Sprint as the front-runners. In India, the state-owned communications giant BSNL has already gone ahead and implemented the EVDO Wireless Broadband Services in select Indian Towns and Cities. With EV-DV, the voice counterpart of EVDO slated to arrive, the wireless internet services scenario looks bright.

Broadband internet services in India especially has come of age only recently. But the rapid advancements in this area belie the late entry into the field by India. Already several private and public service providers compete with each other and the cut-throat competition has already seen price-reduction wars. With the EVDO being taken up by private and public players, the competition is hotting up. Tata Indicom, one of the bigger private players has already introduced the usb internet modem based on the CDMA platform. Tata Indicom was earlier upstaged by Reliance Infocomm another big private player in its race to launch the Internet Data Card or the usb-CDMA Modem. Now the BSNL has entered the arena with a flamboyant launch of the EVDO data card.

Whether it is broadband DSL or wireless broadband EVDO or WiFi, the customers are in for a real treat of surfing the net at blinding speed at virtually down to earth prices.

Long Term Evolution

//-->

LTE (Long Term Evolution) is the trademarked project name of a high performance air interface for cellular mobile telephony. It is a project of the 3rd Generation Partnership Project (3GPP), operating under a named trademarked by one of the associations within the partnership, the European Telecommunications Standards Institute.

LTE is a step toward the 4th generation (4G) of radio technologies designed to increase the capacity and speed of mobile telephone networks. Where the current generation of mobile telecommunication networks are collectively known as 3G (for "third generation"), LTE is marketed as 4G. Ideally, LTE is a 3.9G technology since it does not fully comply with the IMT Advanced 4G requirements. Verizon Wireless and AT&T Mobility in the United States and several worldwide carriers announced plans, beginning in 2009, to convert their networks to LTE. The world's first publicly available LTE-service was opened by TeliaSonera in the two Scandinavian capitals Stockholm and Oslo on the 14th of December 2009. LTE is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) which was introduced in 3rd Generation Partnership Project (3GPP) Release 8. Much of 3GPP Release 8 focuses on adopting 4G mobile communications technology, including an all-IP flat networking architecture. On August 18, 2009, the European Commission announced it will invest a total of €18 million into researching the deployment of LTE and 4G candidate system LTE Advanced.

While it is commonly seen as a mobile telephone or common carrier development, LTE is also endorsed by public safety agencies in the US as the preferred technology for the new 700 MHz public-safety radio band. Agencies in some areas have filed for waivers[3] hoping to use the 700 MHz spectrum with other technologies in advance of the adoption of a nationwide standard.

Web 3.0 : Semantic Web

//-->

Web 3.0 describes the next evolution of the World Wide Web. The term "Web 3.0" has been circulating for some time now, but what exactly does it mean? Web 3.0 is the correct definition is clear since it has been created. When trying to get a hold of an important concept to keep in mind that Web 3.0 is a buzzword not and does not clearly define anything.

Semantic Web

The term Web 3.0 is very often mentioned together with the "semantic Web." Some people refer to as the same semantic Web with Web 3.0, others are considered part of Web 3.0 semantic web. What is meant by "semantic web" mean yes?

A good example in an effort to understand the semantic web has been created by Peter Berkel. Take the words of Paris Hilton, are there really people who think the Hilton Hotel in Paris? The (semantic meaning) of these two words could be interpreted in various ways.

To understand the semantic web we also need to look at the syntax. If we use the phrase "Mike loves Kate", which refers to the composition syntax and sentence structure. Semantics shows that Mike really liked Kate. If we change the "love" became a symbol of the heart, the syntax will be changed, but the semantics will remain the same.

Paris Hilton In the example we see the situation reversed, where there are some semantic but only one syntax.
In communications between computers on the internet, the syntax has an important role. When you request a website appears in your browser, you will actually do the request to the web server. This server looks up and returns your request is in HTML format. Your browser read the HTML syntax and translate it into a page that is designed. Meaning what's on this page will remain unknown to the computer.

The same thing happens when we seek information on the Internet. A search engine searches through billions of pages to find the keywords you have requested. This will show a list of pages that contain the keywords you are looking for. Keyword search engines know that in this paper, but the real content of the pages remains unknown. This can be compared with parrots learn some words, which will replicate without knowing the true meaning of the words.

Using this analogy, the web can now be regarded as a web "document." These documents are all connected to each other in one way or another, but for web application content of this document is undefined. But content is what appeals to us. These documents are about people, history, companies, countries, etc.

Currently we are not talking about the documents again, but about "entities" which in these documents. The purpose of the semantic web is to let computers understand the entity of these documents.
So the semantic web gives meaning to the entities in web pages and relationships between entities. Unlike the current web, this will be web entities.

Benefits of the semantic web

So now we must better understand the semantic web, how we can benefit from this? Take the example of Paris Hilton. If a search engine would understand that I'm trying to find the Hilton Hotel in Paris, all results of celebrity Paris Hilton could be excluded. This brings us to a better, more accurate and faster results. This is an example which is still plain and basic. The next step is an application that understands the Hilton is a hotel in Paris, which can offer my services better. If you are looking at Paris Hilton, the Hilton Hotel can be found, while flights to Paris can be booked in conjunction with a restaurant for dinner. This makes the results based on your request is far more valuable.

Perhaps this sounds very familiar, when you book a flight, you will be asked if you want to rent a car, too. This question has been realized through cooperation several web applications. In the semantic web there is no cooperation or agreement must be made because all the information available universally.

Semantic Web will have the availability of large-scale information. Roughly speaking, there are two different approaches that will lead to the semantic web: the basic-up and top-down approach.
Bottom-up approach meant to add information to all existing documents on the Internet and make them understandable for web applications. This 'information' describes the entities in web pages and all their relationships. This can be done through the RDF or Microformats.

Proponents of top-down approach considers the bottom-up approach is very practical. They do not believe the internet is fully connected. Top-down approach supports the development of applications that can have a better understanding of the data in the document. Think back to the tracking of entities of meaning out of context pages, but most applications that can understand natural / logical language. Hakia (hakia.com) and (powerset.com) is a Search Engine that make an effort at understanding the English language the way humans understand it.

Whatever approach is used, the web will be more meaningful and more valuable. All entities will collect cloud attributes and relationships. A danger would be information overload. Ideally we only want to absorb the information that increases our interests. Needs 'customized personal information' will continue to get more important.

Personal Preferences

Personal preferences can be left under user control. The APML (Attention Profile Markup Language) workgroup has been working on this concept. Your profile can be viewed as an APML file with your personal preferences. Web applications can read these files you are producing information that is filtered to your own interests.

A greater amount of profile information will be outside the user control. At this time, organizations such as Google, Amazon and Yahoo is the behavior of visitors who click on register. In this information the semantic web will become a richer way. Much more is known about the people who visit their Web site. In addition, the web is becoming more widespread. We connect with the internet at any time and will do so more and more, in our browser, our phones, our cars, home devices, Web applications etc. will be able to register information on everywhere. Profiles will be built is full of information about you, without you knowing it.
In a new relationship between the Web and its users, marketers have to 'slip into the conversation of others'. Brands must be relevant to the user situation, setting and desire. When the Semantic Web is realized and managed, it will create huge burden on the exchange of information between organizations and individuals, generating a new level of findability and knowledge sharing.
