History of Bluetooth technology

Bluetooth history

Bluetooth takes its name from a character in history called Harald Bluetooth. He was born in 910AD and the Bluetooth concept takes his name because in 940AD he had the ability to Unite two warring countries, Denmark and Norway. It was because of the uniting of two countries by Harald Bluetooth that the founders of Bluetooth technology took his name for the principle of uniting two components to work together remotely. The use of Bluetooth technology has the ability of linking the different technologies like , computers, mobile phones, printers, headsets etc.

The first to try and discover a way to provide low cost, low power interfaces was a company called Ericsson Mobile Communications. First explorations took place in 1994 to wirelessly connect computers to mobile phones. In 1998, Lund Switzerland saw the formation of like minded companies who united into an association called the Bluetooth Special Interest Group (SIG). Coming from different backgrounds the group included market leaders in laptop manufacturing, the cell phone industry and digital signal processing. These companies where Ericsson, IBM, Microsoft, Motorola, Nokia, Intel, Toshiba, and Agere. These companies now promote development and research into the technology of Bluetooth.

Ericsson Mobile Platforms had two employees Jaap Haartsen and Sven Mattisson which developed the Bluetooth specifications. Developed in Scandinavia Bluetooth technology is able to unite different components from different industries such as computing, cell phones and automotive markets. Based on a frequency hopping spread spectrum it is a wireless technology that combines and simplifies multiple forms of communication into a common secure available radio signal.

The Bluetooth Special Interest Group made a firm commitment to have Bluetooth technology installed in various devices and by 2002 Bluetooth technology was installed in PC’s, notebooks, desktop computers and over 100 million mobile phones had the technology as well as millions of other communications devices.

Bluetooth definition?

Bluetooth is a wireless communications network which operates on a short-range radio frequency. Bluetooth technology has the ability to has the ability to be used on any equipment that has its built in features and can exchange information between various device like mobile phones and computers. Using a short wave narrow bandwidth it uses low power and therefore is medically safe to use, it is also a scientifically sound system with excellent security.

Devices have to be compatible and anyone wanting to use it will have to have Bluetooth profiles to be able to connect to one another. Once the profiles are enabled you should be able to use such things as hands free headsets with mobile phones, and wireless networking and communications which use printers, keyboards and a mouse.

Versions of Bluetooth

Improved features and more benefits have seen Bluetooth improve and change since version 1.0 in 1998 which had many teething problems, like most technology. The lack of devices able to communicate with each other was one of the problems.

Version 1.1 saw great improvements and it became a truly operable product with devices being able to communicate properly.

Version 1.2 had many new features, great extra benefits and vast improvement with voice quality, backward compatibility and was in general a better all round product.

Version2.0 improved even more with features and quality and now version 3.0 is able to communicate with several devices using a Bluetooth master device in which the slave can become the master at any given time. Master devices use there ability and can swiftly switch from one device to another.

One other technology that is similar is Wi-Fi but it uses a different operating system although the operating range is greater with Wi-Fi. However Bluetooth is cheaper to run than the more expensive Wi-Fi hardware. One big advantage Bluetooth has is its ease of setting it up between many devices, its better security and its automated system. Wi-Fi is more complicated to set up and needs to have devices configured to set up shared resources which are more for Ethernet networking. Bluetooth is more powerful and has better connections whilst Wi-Fi is better suited for operating larger networks. 

Microsoft Windows XP with Service Pack 2 or higher is required to operate Bluetooth on a computer. If you run an Apple computer it has been supported by Bluetooth technology since 2002. Nearly all computers now have Bluetooth installed but if not then if your computer has Windows XP with Service pack 2 then a device called a dongle can be purchased. The dongle device allows various devices to communicate with your computer.

Bluetooth is now the world wide wireless standard and has a bright future. In the future High quality audio and video data will have a much higher quality as Bluetooth improves and the alternative for transporting Bluetooth profile data is MAC PHY. Automatic configuration will be carried out by using Topology Management, and broadcast channelling, which will enable Bluetooth in other devises. The chain reaction is already in progress and as more components use Bluetooth technology, manufacturers of electronics will jump on the band wagon and become increasingly eager to make their products compatible. While other technology may go Bluetooth is here for the long term.

Writing Good Headlines

The headline is definitely the most important element in most advertising.

Likewise, it is also the most important element of any selling message "live or recorded, in person or by phone, audio or video" your company ever uses.

It is the opening sentence or paragraph you use in any sales letter or written communication you ever send out to customers, prospects, suppliers or staff. It's the first words your sales persons including your receptionist utter, when they engage anyone in a sales presentation or one-on-one discussion.

Likewise, the "headline," or its "equivalent," are the first phrases you begin your conversation with when a customer or prospect comes in or calls in. It is also the first phrases you state when recording an advertisment or when meeting customers at trade show.

The main purpose of a headline is to grab your prospect's ATTENTION. When I say your prospect, I mean that your headline should zero in on exactly to whom you want to reach your target market. For example, if you wish to reach homeowners, put the word "homeowners" in the headline.

The headline should serve as an advertiment for your ad. It should tell the reader immediately and clearly the essence of what you're trying to say in the body copy. The headline should give the reader a Big Benefit or Big Promise. So, create a headline that tells the right people the benefit you are offering them.

When you write or decide upon your headline-or it's opening equivalent-you have spent at least 80 cents out of your dollar. Stated differently, 80% of your outcome-four fifths of your result... all but 20% of the success of your selling effort is effected positively or negatively by how and what you convey in the beginning.

A change of headline messages can make a 20 times improvement in response or acceptance by your customer or prospect of your proposition. Every headline or opening statement should appeal to the prospect's or reader's or listener's self-interest. It would have to promise him or her a powerful, attractive appealing advantage. If possible, try to inject "news" value or "educational" value into the headline also.

WoW Shaman Guide

In the real word, a shaman is a believer of the spiritual world. In the World of Warcraft, the character Shaman is an integral member of any group that possesses great power and incredible skills. If you are thinking of choosing this character, then continue to read for a guide on how to become a great Shaman.

Finding a group that is in need of a Shaman or making sure that your own skills match well with this type of class is one of the most important things you should take a look at first before you start using the Shaman. It is important that you remember when you start as a Shaman, make sure that your skills match the shaman class and that you join a group that needs a shaman. When put in a group, they integrate the strength needed using their natural abilities.

Getting Started as a Shaman

I must tell you that the race of character for this class is quite limited. Only the Dranei can be Shaman for the Alliance, and the Orc, Trolls, the Undead or Tauren for the Horde. If you are on the Horde side, only the Trolls, Orc, the Undead or Taurean can qualify to be a Shaman. This means you have to deal with these races' weaknesses, but you'll also enjoy the benefits of using them.

Each time you cast a spell, you lose mana points. Your goal is to use your mana points wisely by using moderate approach, not using too much nor too little. It’s best to be moderate about it, not using too much or too little, to achieve more success in using this class. When not used with caution, you either waste time trying to regenerate or lose much needed health points.

Shamans are known for their healing skills, that is why you must try to build up your spell arsenal, your ranged weapons and most specially, your healing spells. If you want to become an asset to the group, whre you get protection, it would be best to study all the healing spells and potions available.

Picking a Shaman Profession

It would just probably be wasting time to work on more physical professions like leatherworking or blacksmithing. The best profession for Shamans are herbalism and enchanting. Skinning could be another facet but only to a small degree. It is vital that you find the right balance between primary and secondary professions.

You may consider herbalism and enchanting as you primary and secondary professions. Nevertheless, combining alchemy and herbalism or enchanting plus alchemy is not a bad idea. Others think that mining (as secondary profession) will help you get items, but it actually wastes your extra time in the game.







If you wish to create money, mixing potions is by far the best business for a Shaman. Potions are usually in high on demand and you could always have them for yourself. If you want to be successful at your chosen profession, spare a good quality of time in mastering your skills by formulating and new potions and useful spells.

Although it can still be useful to pick the tailoring profession, since this makes you capable of working on your own armor, most players opt to just buy their own when needed. Do not worry; for leather armors are available at Level 40 at an available price. During the journey, pieces of armors are given away as rewards. Therefore, choose a profession that will help you develop your skills for your group.

The Important Role of Nutrients in Hydroponic Gardening

Hydroponics literally means the process of growing plants in water using no soil. The principle behind it is that different media bearing all the nutrients of natural soil will support the growth of plants. Therefore, it's these nutrients which are the most vital component in the hydroponics process. When growing plants in soil, the soil contains a whole lot of essential nutrients, which is the reason why fertilizers usually do not contain all the thirteen nutrients. But still, in the case of hydroponic plants, these fertilizers are not adequate and therefore fertilizer formulated specifically for hydropolic systems are the ones that you have to use.

The amounts and proportions of nutrients a plant needs varies. Your better hydroponic nutrients are packaged in solutions labeled as ‘grow’ or ‘bloom’, that way even a novice grower can find these solutions without too much of a problem. As the growing cycle of your plants evolves make sure the nutrients evolve along with it. The elements become depleted as the plant grows, so the solution needs to be changed. At certain times, important components can run out more quickly. In an ideal word, the solution should be changed every two weeks. Bear in mind that the proportion of the nutrient solution and the water stays consistent. If a loss of water occurs due to evaporation, the fertilizer levels will increase potentially causing serious damage to root systems.

The hydroponic nutrient solutions available are typically sold in a concentrated form. The grower must follow instructions and consider the plant's unique needs when he or she mixes it. For instance a weaker solution should be put for plants in poor growing conditions like overheated gardens, low lighting or just crowded plants. Even newly planted cuttings will benefit from a weaker solution. You will want to use a normal (regular) solution for any plant which is normal and healthy. You are ripe for a stronger solution if your garden can handle high growth with enough carbon dioxide distribution and lighting. Natural sunlight or good grow lighting like LED grow lights are key. When using fertilizer on your plants you must increase the amount slowly over time so that you to keep the plant from burning up.

Even with a concentrate to water ratio range of 150-600 ppm, the level for many plants is 300-400 parts per million. Keep in mind that these must be mixed with water and not with another part of nutrient solution.

Right now, we know we need something more than just soil-based fertilizer, but what do we use?  The essential thing is to know which nutrient to look for. You have to first and foremost decide on the growing medium such as stone wool, coco etc. For instance, if coco is the medium you are using, go in for specific nutrients like canna coco nutrients. Super Veg A or Super Veg B would be ideal, and is a great formula for a vegitable in the crop stage.

The nutrient required will depend upon the medium that is to be used. Basically the organic or best hydroponic nutrients are made up of different combinations of nitrogen, potassium and phosphorus. Nitrogen is essential for leaf growth and development. Potassium will aid in the processing of cell production and phosphorus is the agent responsible for developing roots and flowering.

Creative and a Pack Rat? Make Your Own Classic Movie Poster

When unpacking in my new apartment, I realized that I do not like to throw anything out. This includes old newspapers, magazines and postcards. I decided that instead of decorating my walls with prints, I would make my own classic movie poster. It’s an excellent way to clean out the clutter in your house, as well as a way to show your creativity.

Anything Goes When Making a Classic Movie Poster

There are lots of different ways one could make a classic movie poster. At Chicago’s Halsted Market Days, a local artist was framing record album covers using soundtracks of films such as Breakfast at Tiffany’s or An American in Paris. This is a great way to make a classic movie poster, because it’s very inexpensive and easy to do. Go to the local used record shop where you can buy records for less than $5. For less than $30, you can buy an inexpensive, but nice-looking frame at a drugstore.

Another way of making a classic movie poster that involves actual work is making a collage. A collage is a great way to get rid of a lot of old magazines and newspapers. Because most of the material you already have at home, this is again, a very inexpensive project. You’ll only have to buy a poster board and a frame. Along with magazines and newspapers clippings, you could also use covers from VHS tapes, DVD’s or CD’s.

Use Your Imagination, but Remember People Have to Look at it

The only “danger” in making a classic movie poster on your own is that it might end up looking like a kindergartner’s art project from school. While beauty is subjective, and in the end, you have to put together what you like, there are tips for making your poster presentable and tasteful.

Having a theme is a great start. This theme could be a color scheme – using only black & white photographs will give the poster an old Hollywood glamour feel. You can also concentrate on one star, or even better have some sort of general theme in mind. My poster featured film stars of the 1940’s and 1950’s.

Another good idea would be to have shots of famous pairs – Bogie and Bacall, Spencer and Hepburn, Fred and Ginger. You can also have a classic movie poster featuring famous screen clowns like Charlie Chaplin, Abbot and Costello, or Laurel and Hardy.

The most important thing to remember when making this poster is that it reflects your taste and what you believe to be classic film. As long as you put your creativity into it, any movie poster will look like a classic and don't be worried if your poster reflects Shaft more than it does Casablanca.

Making your own classic movie poster is an excellent way to clean out the clutter in your house, as well as a way to show your creativity...View more articles at www.posters.jsgenterprises.com.

Everyone Needs a Passive Income If They Are Looking At Retirement

A hail to various creativeness that made possible the way towards increased wealth to almost anyone even to the emergent figure of baby boomers by creating passive income so that they may have something to boast with their retreat portfolio. Let us face it, the social security system has failed to fulfil the security needs of the people and what was originally created as a safety net, has been fond to carry a lot of gaps.

People have finally come to realized that even if you dedicate your life working for a firm, the pension/retirement benefits that you will get are more likely not to give you the value that you need especially when the need arises and you put it to use.

**It is a fact that American firms are now miserly with their benefits and also curtailing their contributions.

I know of one such firm who did not think twice before they cut short the careers of its workers who had labored for 20 to 30 years by paying out only 30 percent of their retirement benefits. This report is no longer a new one and it is already becoming a center of all the attention especially that the time for the baby boomers to retire is about to come. The thing about us believing into the thoughts and promises of living an entitled way of life is only a fallacy.

There is a friend of mine who worked for a single firm for 30 long years and at the end of those 30 years when he retired, he now receives a monthly retirement check of 30 bucks. The net result which this man got in life is that he has to work for a living even after retiring and as we are all aware, a lot of people are just doing this.

It is true that many individuals are still working somewhere to make up for their post-retirement income. Many such individuals turned to the web based for business opportunities only to find that the place is full of failure stories primarily because the Internet based business is mostly based on distributorship modules with no real clients buying any product. Marketers, marketing to other marketers who jump from firm to firm looking for the next get rich fix that never really works has been the name of that game up until now.

This is where Thomas Prendergast Chief Executive Officer of Inetekk and founder of Veretekk come in who has made a name for himself by holding the hand of the average guy like you and me, to start a home business Internet based. Prendergast was recently interviewed and spoke of the reward of the distributor model in a short period of time that even if it can really sustain you an income, it wont be for long until it breaks down therefore not giving you the long term success or profits that you always wanted.

Putting up an investment with such Internet based commercial enterprises is something that most people are already annoyed of doing since you will only end up wasting a fortune for some overused and old lists of leads which can't even give you a reasonable way to build a viable client base. Wouldn't you find it a more attractive option if you were to plug in your financial and individual resources like time and effort for clients who are used to your company and are familiar with your products or services?

Is it really possible that you can generate an abundant flow of passive income without having to experience recruitment of individuals, trading and rejection? Don't you think that is way too imaginable? If that sounds like a dream... Well all you "baby boomers" out there, wipe the sleep bugs out of your eyes... it isn't, It's just good business.

Learn the Tips for Making a good Weld with Stick Welding

If you want to learn Welding it will take practice and a little patience to learn to do it in a way that will produce fine welds. This is an important thing to remember although some people may say they never had to practice much.

Welding is one of the basic methods of welding that many students learn as they are just beginning to learn welding. This is also a method of welding that is high in demand because people need this help whether they are working iron, pie, boilers or building ships.

You will find that you will need the skills of all types of positions including flat and horizontal and ventricle or overhead welding. All of these will take some time to learn and some will be more challenging than others.

Here are some tips to help you Stick Welding :

1. The right electrode for the job -- many people aren't sure of the size of the electrode they should use and this is important to know. The size of the electrode will depend on the situation you are welding within. In this situation you will be fighting against gravity if you are doing the weld vertically so you will want to use an electrode that is AWS classified as 7018 because they are low in their powder content.
2. A weld shelf makes a good guide -- if you are doing vertical or horizontal welding you will need something that the electrode can follow so you don't loose any of it to gravity. You can do this by creating a serious of little shelves so you can do a section at a time so that you can continue to work above a weld that you have already laid. This will create a situation where one puddle will freeze in time to hold the next weld.
3. Don't undercut if possible -- this can happen because you have to weave the electrode and sometimes your work may be gouged and not have enough fill metal. When this occurs, you will be working against gravity because it will work to pull your fill metal away from the space you are working. You can reduce your puddle size to help you have more control in this situation.
4.You will be doing yourself a favor if you stay away from odd sizes of metal and stick with the standard sizes of metal. These metals will be easier to find and you can weld them fester. Stick with the ones that are AISI-SAE 1015 to 1025 so that you can be sure that you have what you need.
5. Make sure you know your arc length -- a good rule of thumb is to use an arc length that is the same distance from the metal as your electrode's thickness. As an example, if you have an electrode that is ¼" thick, then have your arc ¼" thick. Also remember that as you use the electrode, you will have to move it closer to the metal.

Following tips such as these will really help your weld be more controlled and much more even.
