Do not study this guide if you are looking for a special type of toothbrush. Do not bother to read this guide if you are investigating facts about the various tooth whiteners. Do not set-aside time to examine this guide if you are intent on the discovery of more information about dental schools. Do read this article if you have an interest in technological developments.

Bluetooth does not describe a dental condition in which a patient has blue teeth. The term “Bluetooth” signifies a special new technology, a technology of the 21st Century. The devices with Bluetooth technology allow the user of such devices to conduct 2-way transmissions over short distances. Usually the distance between the communicating Bluetooth devices runs no more than 150 feet. . The individual who has access to two or more devices with Bluetooth technology has the ability to carryout such short-range communications.

One big advantage to having access to some of the devices with the Bluetooth technology is the opportunity one gains to conduct a “conversation” between mobile and stationary technological items. The Bluetooth car kit underlines the plus side of having access to the Bluetooth technology. The Bluetooth car kit sets the stage for a “conversation” between a mobile and a stationary electrical gadget.

For example, the Bluetooth car kit permits a cell phone in the garage to communicate with a home computer. Thanks to Bluetooth, a car driver with a cell phone could sit inside a car and send a message to a home computer. By the same token, Bluetooth technology could allow a car to send a message to a personal computer. Such a message could inform a car owner that the motor vehicle sitting in the garage needed an oil change, rotation of the tires or some other routine procedure.

Not all of modern automobiles come equipped with Bluetooth technology. So far only Acura, BMW, Toyota Prius and Lexus have chosen to provide the consumer with this special feature. In order for the car owner to benefit from the potential of Bluetooth technology in a motor vehicle, all of the devices with that technology must use the same type of profile.

For example, if a car audio system contains devices with the Bluetooth technology, then any of the communications that take place between those devices require Bluetooth equipment that uses the same profile. Such restrictions typically specify that the Bluetooth car kit will work only if all of the inter-device communicating involves equipment that operates under the hands-free profile. In other words, a Bluetooth car kit would not be expected to allow a cell phone with a headset profile to communicate with a computer that had a dial-up networking profile.

Of course Bluetooth technology is not confined to the automobile. It has also been responsible for allowing young teens to listen to music from an iPod, while at the same time being equipped and ready to handle any number of cell phone calls. On other occasions those same teens might choose to use the Bluetooth technology to send selected images from a digital camera to a home computer.

The Bluetooth technology has demonstrated the ability to lay the groundwork for creation of a mobile entertainment system. It could also facilitate the quick assembly of an operating and mobile office space. The father of the young teen who was listening to a iPod could very-well be the traveling business man at the airport, the man who must wait for a delayed flight. Access to the Bluetooth technology would give such a man the ability to set-up a temporary “office” in the airport terminal.

Once that same traveling businessman had reached his destination, and once he had settled in a motel room, then he might use the Bluetooth technology to send signals from a laptop computer to a printer server. Both younger and older adults have demonstrated that Bluetooth technology is definitely a technology of the 21st Century. Who could guess that the Bluetooth technology got its name from King Harold, “Bluetooth,” of Denmark, who lived back in the 10th Century? King Harold sought to unite the countries of Scandinavia, much as the Bluetooth technology helps the different types of informational devices to work in unison.

The value of freedom in a country is priceless. If one country has freedom of speech and thought then they are sure to have a bright future ahead of them. How so? If a society has freedom of thought then they are free to explore their interests or whatever else that may pique their curiosity, which could eventually lead them to great knowledge and amazing discoveries.

Take the United States for example. America has surpasses all the other countries of the world not only economically but technologically as well. Although it is true that most technological inventions and other scientific discoveries did not really originated from the Americans themselves but rather are attributed to citizens of other countries. However, it is undeniable that these technological inventions are enhanced and further developed in America. Thanks to America’s innovative patent system these technological inventions are put to better use.

Just what is a patent you asked? The term “patent” is generally defined as a set of exclusive rights granted by the government to a person for a certain period of time (usually for 20 years) in return for the regulated, public disclosure of some information about their invention. It was Thomas Jefferson who initiated the first national patent system in the United States of America during the year 1790. From then on, this exclusive right has been protecting the inventor’s interest by preventing other people from copying, using or selling the already claimed invention.

So how exactly are these patents significant in technological advancement? According to the World Intellectual Property Organization or WIPO about 90% to 95% of all the world’s inventions can be found in patented documents. However, these technological inventions comprise only a small percentage of all the patents that are applied for and granted. Therefore it is safe to assume that the latest patent applications are the kernel of technological advancement.

Take a look closer at the Internet. This technology has undergone numerous changes from the time that the concept of the World Wide Web was first introduced a few decades back. In an attempt to put Internet into better use, various inventors who aim to further develop and enhance the existing models filed numerous patent applications that are related to this technology.

One of the latest patent applications is called system and method for scoping searches using index keys. The invention involves a set of index keys, which is to be included in an index search system that are related with the scope of the search instead of the content of the documents, which are the target of the search. These so-called “scope keys” enables the scope of the search to be customized, thus reducing the number of documents that a search supposed to sort through in order to acquire the results.

Another latest patent application that is related to technological advancement in the Internet is the “system and method for performing a search and a browse on a query”. Now, in this invention a search and a browse on a single user query is executed. Then a refined query is chosen from the results of the first user query. After that, a list of concepts from a first directory that are related with the refined query is acquired.

Here, the “concepts” are categorized in a hierarchical relationship. Concepts with broader scope are obtains a higher position. Meanwhile, the concepts with narrower scope get a lower position in the hierarchy. In addition, a list of web sites that related with the search concept is also acquired from a second directory.

The forming intent-based clusters and employing same by search, is also a patent application that is related in further enhancing the Internet. This patent application is associated to a system and method that will be use for identifying and forming intent-based clusters based on search requests that were sent by the users to the search engines, as well as to the search engine utilizing the formed intent-based clusters to answer the search requests made by the users. To be more precise, the invention is associated to recognizing and utilizing intent-based clusters so that a search made by a user with similar intent may receive a respond more quickly and efficiently. Most importantly, with search results that more directed to the search of the user.

All three patent applications are dedicated in making the Internet searching process less complicated and not to mention, much more efficient in terms of coming up with results.

Today, patents are considered as the leading source of technological information that is vital in technological advancement. Thanks to the innovative Information Technology industry, particularly to the Internet, the general public can now easily access these constructive documents. Just about anyone who is familiar with the Internet can browse through different patent databases available and obtain the specific patent document that they needed.

There are various patent databases that are accessible by the public, USPTO, EPO, JPO, to name just a few. For instance, if you are looking for patents that are related to a certain technological area you will find countless information regarding the entire process of technological innovation, such as the evolutionary path of a specific technology, it’s technological development, technological diversification, technology merges, as well as the major players in specific technological area, and the key points of the specific technology.

The secret behind each major technological advancement and inventions are thousands of patents that were applied, filed and then put it into practical use. Fortunately for us the public are well aware of the significance of patent application in developing tomorrow’s technology. The number of patent applications is growing at an enormously fast rate. Inventors not only from America but from other countries as well, are diligently working on their inventions as well as on patenting their ideas — a clear indication that our nation’s future is indeed in good hands. For as long as the American government continues to nurture innovation, then they will remain as global leaders both in economy as well as technology.

From the heavy cordless phones of the 1980’s to the smart phones of today, cellular phone technology has undergone a incredible change. But have you ever wondered how you can call to your well wisher in the whole world with the usage of a mobile phone? You also have knowledge about the main features such as WAP and GPRS from the cell phone vendors and service providers. But you must aware of what they really mean?

There are numerous mobile technologies. So next time, when you are going to purchase a phone, you should know what technologies it has.

Generations of mobile communications

In the late 1970s, the first generation (1G) of mobile communications was introduced; it was primarily used for voice transfer. Second generation (2G) systems came into existence in the early 1990s and was further developed to 2. 5G, which includes high technologies such as TDMA, GSM and CDMA. These technologies were used for voice and data.

The next generation of mobile communications is 3G which delivers data speeds from 384 kbps to 2 Mbps and over wireless interfaces such as GSM, TDMA and CDMA.

Mobile phone access technologies

Frequency division multiple access (FDMA)
The first-generation analog mobile access method; for each call, FDMA uses separate frequencies. For instance, if there are four stations, each will receive their own frequency. So there is no interference between them. It reduces interference, but limits the number of users.

Time division multiple access (TDMA)
TDMA allocates unique time slots to each user within each channel, thus allowing many users to access the radio frequency without anyone’s interference. Each mobile conversation uses only a particular frequency slot of the time.

Code division multiple access (CDMA)
Commercially introduced in 1995 by Qualcomm, CDMA quickly became one of the world’s fastest-growing wireless technologies. 3G CDMA networks provide more capacity for voice traffic with high-speed data capabilities, hence many cellular service providers are now building or upgrading to it.

CDMA is used in both 2G and 3G wireless technologies. Indian Cell operators such as Reliance IndiaMobile, TATA Indicom, BSNL and MTNL’s Garuda all use CDMA2000 technology and its variant CDMA1x.

Global system for mobile communications (GSM)
GSM is now the worldwide standard technology for mobile communications. It is developed on TDMA protocol in Europe. GSM provides a high level of security, globally accepted technology standards and superior sound quality.

For any GSM phone to work, it needs a Subscriber Identity Module (SIM), a card which contains your telephone account information. So, an Indian GSM phone can be used in any part of the world.

Wireless technology platforms

1) GPRS
GPRS (General Packet Radio Services) is an enhancement to GSM technology that integrates GSM and IP technology. GPRS offers to access the Internet at the very high speed. So you can check your email on the move and surf the Web at very high speed. Currently BPL Mobile and Hutch (Orange in Mumbai) offer GPRS services in India.

2) WAP
In this high technology age, people on the move need any-time access to the Net. This is where WAP comes in. It facilitates us to Internet access from cell phones. It is an open standard for wireless protocols that is independent of the service providers. The cell phone must have a WAP browser to display Web content. Now-a-days, cell phones often come equipped with WAP browser and GPRS technology.
WAP and GPRS also enable the user to download games, send mail and even transfer your messages to your PC.

3) EDGE
The new EDGE (Enhanced Data GSM Environment) interface has been developed specifically to meet the bandwidth needs of 3G. This technology is promoted by Ericsson, it also offers high-speed data transfers over GSM networks with just a software upgrade to the handset. EDGE technology allows speeds up to 384 kbps.
