Mobile wireless technology continues to advance at an amazing rate and there is no doubt that the cutting edge innovations of today will be the popular tools of tomorrow. As of now, Bluetooth wireless stereo headsets are a wonderful way for folks to enjoy their music and take their telephone calls without missing a beat.

Major Flaws Of The iPhone

iPhone 3g Flaws

The iPhone has been hailed as the best and greatest cell phone to ever come out. However, many people feel that the iPhone has many major flaws.

Not Available To All

One of the major iPhone flaws is that it is not available to everyone. This phone is only available to one carrier” AT&T. If the iPhone truly wanted to expand and change the world of cell phones, it would be available to more than just one carrier.

Slow Internet

AT&T only offers one type of internet service to iPhone customers. This is a major iPhone flaw. Other internet providers on other phone networks are much faster and more efficient.

Poor Battery Performance

If you have an iPhone, one of the iPhone flaws is that you will have to send your phone in every year or two to have a new battery replaced. Not only can you not do this yourself, but you will also need to pay to have the battery replaced. Except several days of withdraw from your iPhone while you wait to have the battery replaced!

No Global Positioning System!

Almost every new phone these days has a global positioning system. However, despite the huge price tag, a major iPhone flaw is that it does not have a global positioning system. There are programs, like Google Maps, available, but you have to know exactly where you are to get correct information.

If you choose to purchase an iPhone, make sure you know the iPhone flaws before spending your money.

No Adobe Flash Support

Even though iPhone is a more than capable web device, the biggest drawback as a web device is that the iPhone doesn't support Adobe's Flash technology, which means many multimedia-rich sites remain off limits. This should be overcome in the future as Adobe is apparently going to make its technology iPhone-friendly. The question is when?

No Video recording

Despite the iPhone's built-in two-megapixel camera, Apple didn't include video capabilities. This from a company that provides computers preloaded with iMovie and provides video viewing capabilities with most of their iPod range. So if you want to record video, you'd better talk to Sony!

No multimedia messaging service

There are some things dirt-cheap phones do that the vaunted iPhone cannot. If you want to open an image sent to you via MMS (multimedia messaging service) from one of the dirt-cheap phones then don’t get an iPhone. The deficiency of support for Multimedia Messaging Service (MMS) is one of the most annoying iPhone flaws.

How do I Send Faxes Online?

The method of sending a fax actually depends on the operating system in use.In large companies like MyFax or eFax, it is simply like sending an email with the documents attached.

It is the usual way with many email-to-fax services. In MyFax,you send a email like normal, but address it to faxnumber@myfax.com instead of an email address.com.

So, to send a fax to 1-888-999-1111, you address your email to 18889991111@myfax.com. Any files you want sent you'd send as attachments to the email, and to include a cover page with your fax you'd simply enter something into the body of your email message.More information how it works may be read at this MyFax review.

GPS Gadgets and How They Work

GPS units may seem rather on the pricey side at first glance, but if you take the time to understand how they work, it helps to make the cost more fair in your mind.  More often than not, we are seeing GPS systems being automatically included in PDAs and cell phones as well as the newest car models.  The succeeding paragraphs will endeavor to provide a simple overview of how GPS systems work. Full technical details can be found in other articles published on the Net.

Here We Go

You may be astonished to learn that there are over 2500 satellites that are orbiting our planet at this very instant.  Quite a significant percentage of them are global positioning satellites.  Yet only 36 of them are actually still in operation with many others having been retired.  A low-power signal is transmitted by the satellites which can be received by the GPS system in your car or cell phone.  By accurately measuring the distance from three of these satellites, the GPS system can calculate its exact position on earth.

When their solar power panels are completely opened, a GPS satellite can be nearly seventeen feet wide.  They are powered by the sun and also by a backup battery supply if needed.  They generally last ten years or more if all goes well. The longest running satellite is from 1978.  Rumor has it that this one often relates stories from the old days when satellites had it much harder than they do today. Just a little satellite humor there.

But Seriously

So what is a GPS receiver?  Any electronic device that is able to receive signals sent by the GPS satellites is a GPS receiver.  There was probably a GPS receiver on that cruise ship you were on last summer, another in the taxicab you had to the airport last week and then there's that Navigon 7100 GPS that your boss just bought for his car.  The current average cost for a personal GPS unit is about $300.  A price tag of $300 isn't that out of line when you consider that you didn't have to pay for all those gps satellites to be built and launched into space, nor do you have to pay a fee to use the signals from them.

The US government is responsible for paying the costs involved in manufacturing and launching satellites into orbit.|Our government here in the US has resolved to take on the costs involved in creating this network of GPS satellites. All you have to do is click on your GPS system in order to make use of the information that is freely broadcast by them. Hopefully now you have a better understanding of how your GPS system works the next time you switch it on.

Your Guide To Bluetooth Adaptors

Bluetooth adaptor is used to establish Bluetooth connectivity across very short-range radio frequency bandwidth, making it a refinement of radio broadcasting. A connection between mobile phone and headset or comuter and a mouse could be made.

A Quick Recap of Apple iPhones Origins

A Brief History of the Apple iPhone

Known for making a large variety of advanced technical products, Apple has become a famous brand name among consumers. People began talking about Apple’s new iPhone long before it was released in June 2007, decisions were made about the essentials it would have, and what new technologies might come with it. It was no surprise, that what had people talking was the idea of having an incredible new ground-breaking device, that would be an iPod, mobile phone and tool for accessing the internet all in one.

Launching Apple iPhones

The visible or at least documented history of the Apple iPhone starts with the instruction of Steve Jobs, CEO of Apple, instructing engineers to start researching touch screens, which at that time he probably still had the development of Apple tablet PCs in mind. Steve Jobs announced in a conference held in April 2003, that Apple would not be focusing their attention on traditional PDAs or tablet PCs.

The new direction was to move forward in evolving the technologies used in cell phones and the options provided with them. Word got out during the January 2007 MacWorld Expo, that the Apple iPhone was going to be released to consumers in June of that same year. At another conference that same year, it was revealed that the Apple iPhone would sustain third parties which would create Web 2.0 applications and that users could access this through the internet.

Consumer Ready and Future Developments

When the Apple iPhone went public on June 29, 2007 hundreds of people began to line up in front of stores before opening hours in order to be amongst the first let in, so they could quickly grab one. At first when the Apple iPhone was introduced to the public, it was available in either a 4GB for $499 or 8GB for $599 however, it was quickly evident that the 8GB was far more popular in demand, so Apple soon stopped making the 4GB.

Moreover, as a further development, the price was radically reduced by $200 in September, for which Apple was quite widely attacked because the sudden drop in price was believed to be unfair. Apple iPhone’s initial popularity was not close to the level Apple had anticipated it would be.

For example, the sales for the first weekend were initially estimated to be somewhere between 200,000 and 700,000 products. However, only approximately 145,000 iPhone activations were registered that first weekend.

In addition, Apple iPhone applications were initially only offered to those who agreed to a two-year subscription with AT&T, and that included some offers that would not pay off for everyone. There was also wide media coverage of a 300-page bill, after which AT&T made a change in its billing practices.

The Apple iPhone was released internationally in France, the United Kingdom, Europe and Germany, towards the end of 2007. In Europe the Apple iPhone was only made available to the public through one preselected company and that seem to raise some legal concerns.

Foreign travel with your Business Mobiles

We have been told by the media, Ofcom, and from phone networks themselves that prices for international roaming call charges will drop.  Will there be a real change in the future or is it more of the same old story?

At the moment, financial departments of both large and small companies are looking for ways to reduce the costs of a business mobile and international roaming.

An important issue when making calls with business mobile phones in other countries is the information that is provided to companies and individual consumers.  How much are we going to be charged? Is it possible to utilize one's phone time overseas? What are other ways to save money?

Lets take a brief overview at what is on offer in the market place.

Orange ‘business customers’ can make UK calls to 28 countries from their minute bundle, similar offers are available on o2 and T-mobile.  Orange also offer ‘Business World Traveller’ which will give up to 50% off standard voice roaming rates and up to 25% off roaming data.

You can find a similar service provided by Vodafone called Passport.  You can also take advantage of reduced call charges when you call from another country.  At only 75p connection charge each call when in another country, you can call people while paying your regular UK fees.  You can talk to Vodafone about the service directly by dialing 5555 on your handset.

o2 have what’s called ‘International Traveller Service’ which allows customers to call from Europe to the UK for £0.30p per minute.  However, if you are calling from other parts of the world then the charges can vary from between £0.81p to £1.20 per minute. 

T-mobile also have competitive roaming offers.  T-mobile charge between £0.38p and £0.55p per minute to call the UK from Europe.  Receiving calls with T-mobile have recently fallen meaning the cost is between £0.13p to £0.20p for Europe.

Just tell us where you need to make your call to and we will set you up today.

If you are regularly visiting a country and using your business mobile phone to call the UK, one option is to buy a local SIM card.  In that case you have a local number for the country you are in.   Within certain countries it would not be possible because you will have to be a documented resident.

Other options include purchasing international PAYG/Prepaid SIM cards in the UK which offer roaming savings, in some cases up to a 50% to 60% reduction in call charges.

Networks are competing and the market for international roaming is becoming more and more competitive. I am positive that roaming call prices around the world will keep getting more and more competitive.  After all, the networks are in competition with one another which will drive prices down further. 

Finally, whilst the networks are bombarded with bad press for over charging on roaming I believe they are reacting in a positive way that will benefit business mobile users in the UK.

THE PRESS-ITS RIGHTS AND RESPONSIBILITIES

According to Napolean, four hostile newspapers are to be feared more than a thousand bayonets. Napolean recognized the power of the press through this statement. So powerful is the influence of the press in modern times that it is called the 'Fourth Estate', that is, the fourth most powerful institution influencing social order.

The press, that is, newspapers and periodicals are a sort of a mirror which reflects social occurrences and movements. It can Be called 'eyes and ears' of the world. It is indeed the chronicle of current history.

The press plays not merely the passive role of reflecting or recording events. It plays a very active and positive role of influencing events and shaping them. Through its publicity campaign it can make or mar the image and fate of public men, institutions and products.

It is an effective and powerful means of expressing and moulding public opinion. The press creates awareness among people on matters of public interest and thereby educates people in general.

The press serves as a means of communication between the rulers and the ruled and is an effective medium of ventilation of public grievances and hence makes the working of democracy meaningful. The press is the watchdog of democracy. In fact the free press is the greatest safeguard of democracy and a necessary condition for its success?1?hat is why a dictator's first attack is usually on the freedom of the press.

In our country we have been witnessing the power of the press. We are familiar with its crusades against social evils, bad administration, and against the attempts on the part of the government to curb the freedom of the press. Powerful investigations conducted by leading dailies and their campaigns have exposed persons occupying even the highest positions in society and government.

But in the power of the press lies its responsibility also. It must not indulge in cheap sensationalism, lies, misrepresentation and slander. It should not use its power and influence for blackmail or personal vendetta, but should use them with a sense of responsibility. It should be remembered that gross misuse of power by the press would harm the cause of democracy and pave the way for dictatorship whose first victim would be the free press itself.

In the health of the press lies the health of democracy.

FLOODS

Floods have become an almost regular annual feature in India. We read reports like the Brahmaputra, the Ganga, the Jamuna, the Narmada, the Tapi and the other small rivers getting flooded almost every year.

Floods may be caused by excessive rainfall in foe catchment area of a river, by earthquake, by breach in a dam. In,North India floods are caused even in summer by the melting of the snow in the Himalayas.

Floods take a heavy toll of life and property. They flood vast areas of land. Low-lying areas are completely submerged in water. People lose all their belongings and become homeless. Standing crop and goods lying in shops, warehouses and factories are destroyed. Roads, railway-lines and bridges are damaged. Means of communication are disrupted. Failure of electricity plunges vast areas into darkness.

People stranded in floods have to remain without food and water for days together.

Floods destroy the uppermost fertile layer of the earth and turn cultivable land barren. This long-term effect of the flood is far more damaging than the other short-term effects.

Even after the flood has receded, it leaves behind a trail of death and destruction. Fallen buildings, breached roads, rail lines and bridges, uprooted trees and telegraph poles, dead bodies of human beings and animals sunk in deep mud present a ghastly sight. Often epidemics like cholera and jaundice spread in the wake of the flood.

Fortunately modern means of transport and communication make it possible to provide quick relief to the victims of flood. Food, medicine and other essential things are air-dropped from helicopters to the people trapped in the flood. Government and voluntary charitable agencies come forward to help and rescue the victims.

Though timely and efficient relief measures go a long way towards mitigating hardships caused to the people by the flood, government should devise long-term measures to prevent the recurrence of floods. These measures include building up of dams, canals and embankments, walls, growing more trees and afforestation.

Government and voluntary agencies should also devise a permanent relief machinery which would provide instant relief to the victims of flood.

SCIENCE AND HUMAN HAPPINESS

Ours is an age of science. Science has revolutionized our way of living. Our life-style now depends on innumerable discoveries and inventions of modern science.

The telephone, the television, the wireless, the radio, the teleprinter satellite communications and the fax are some of the marvels? of communication. News, views, messages. and even documents and photographs go round the glob with lightning speed.

Machines of incredible skill, power and efficiency have boosted trade and industry. Almost everything is produced on a large scale, quickly and cheaply.

Air-conditioning, refrigeration, plastic, steel, man-made fibers, varioils home-appliance? and gadgets like the washing machine, vacuum cleaner, gas-stove, grinder-juice-mixer have changed the appearance of our homes.

Modern sanitation and wonder drugs like the sulpha drug and antibiotics, an aesthetics and vitamins have helped man in his fight against ill-health and diseases. Many deadly epidemics Have been completely wiped' out, corneal grafting, transplantation of kidney and artificial heart plastic surgery and lithography are some of the marvels of medical science.

Computers have made the process of analysis, computation and decision-making easier and faster than ever before.

The cinema, the television and the video have opened out new worlds of mass entertainment and instruction.

Use of steam as the motive power started the process of industrial revolution. The second phase of the industrial revolution began with the discovery of electricity. The world has been ushered into the third and most marvelous phase of industrial revolution with the developments of modern electronics. All the machines are becoming smaller handier and more sophisticated with the use of electronic devices.

Rockets and space satellites have enabled man to land on the moon. Voyager II, the American space satellite has sent us important information about the planets and space.

All these discoveries and inventions of science have eradicated many deadly diseases, increased man's longevity and have brought within common man's reach luxuries and comforts which even kings and emperors could not enjoy in the good old days. In short, science has provided man with all the material means necessary for a happy living.

TREES - OUR BEST FRIENDS

A friend always does a good to us even if we do harm to him. Similarly, tree gives us fruits when we throw stones at it. So a tree is our friend.

All our food comes directly or indirectly from trees. Food grains, cereals, vegetables and fruits are supplied by trees. Even non-vegetarian food comes indirectly from trees, because animal live on grass, and other parts of trees.

Besides food, trees provide important raw materials such a wood, cotton, jute, wood pulp to make paper, rubber an turpentine for our industries. Industries provide employment to people. We also get many valuable medicines from trees and tree products. We get so many things from forests that forest are rightly known as green gold .Trees provide shade to tin travelers and animals and shelter to innumerable birds and insects.

Trees keep the environment clean. They take away the harmful carbon dioxide from the air and give oxygen. In this way they reduce air pollution. Forests retain humidity and attract rains. There will be no rain if there are no trees.

Trees check strong currents of wind and water and then prevent soil erosion. They thus help to preserve soil fertility. They prevent the fury of floods. Roots of trees keep the water below soil clean.

In fact, all our basic necessities, viz., air, water, food, clothing and shelter come directly or indirectly from trees. owe,  our very existence to trees. Life would be unthinkable without trees.

If there were no trees, there would be no rain and land w turn into an arid desert. Mankind will perish, for want of f drinking water, fresh air and sufficient humidity. So we should ever remain grateful to trees. To conserve existing trees should our prime and urgent duty. Reckless felling of trees and min destruction of forests should be made a crime punishable utmost severity.

The Power Of Positive Thinking

Ask For It

Many of the richest rewards of life, material as well as spiritual, are never acquired simply because they aren't asked for. It is because this principle is so simple that it is so frequently not even recognized, not put into daily practice. Yet it is a fundamental principle of life.Is it good? Is it just? Are you prepared for it? Then— ask for it!

Adopt the positive attitude, and ask for what you want from life.There is a positive quality of magic in this proposal. But be very careful what you ask for, since in all probability you will get it. Midas asked for the golden touch and turned his beloved daughter into a golden image. On re­flection, you will realize that you have asked for most of your triumphs and, through the very request, motivated their achievement.

Ask for it. But test it first. Is it good? Is it just? Are you equipped to have and hold and develop what you desire for good purposes? Jane Froman, the singing star, never lost the positive approach of her childhood. She recalls an incident of student days at the University of Missouri. Regulations prohibited her from going to St. Louis to hear the opera. She couldn't leave the campus except to visit parents or friends who were approved by the school authorities. She had no friends in St. Louis. So Jane Froman went straight to her dean and asked for what she wanted. The dean firmly informed her that he wouldn't change the university regulations to suit her convenience. Then, warmed by the intensity of her request, the dean smiled and invited her to be the guest of himself and his wife at the opera. She had asked for it.

The Secret Of The Positive Way Of Life

Perhaps that was just a lucky exception that could have happened to anyone? Perhaps, but Jane Froman doesn't rest content with exceptions. She has learned the secret of the positive way of life. She asks for what she wants. Jane was badly broken in body and spirit in a plane crash near Lisbon, Portugal, during the war. She yearned to return home, but transportation wasn't available. All doors seemed closed to her.

Then she wrote a simple letter to President Roosevelt, explained her predicament, and asked for transportation home. She barely had time to pack to take advantage of the reservation the President made available to her. Oh, well, that was just a lucky exception! Perhaps, but how do you account for this? After returning home and undergoing a series of operations that patched her together, she asked for an automobile. She was told she was zany, that thousands had been waiting for cars and were paying many hundreds of dollars over list prices. Jane simply looked up the name of the president of the automobile com­pany that made the kind of car she wanted. She wrote to him, a stranger, and asked for a car.

What answer did she get? Just a question. What color did she prefer? Jane Froman knows that you get many good things by asking for them. More consistently than many she has the positive attitude that wins. If she had a negative or passive attitude, she wouldn't have gone to the opera, come home quickly for the hospitalization she needed, got the car she wanted. She didn't moan, "I can't," which as often as not means "I'm so negative in outlook I won't even bother to try."All of us occasionally have got what we simply asked for. Sometimes we ask for too much, ask for things that do not meet the test, and refusal makes us skeptical. Ob­viously we can't have everything we ask for. We can have our fair share of the good things of life, however, if we apply the suggested test and adopt the positive atti­tude as Jane Froman and most effectual people have al­ways done.

Do you ask for too little?

Sometimes we defeat ourselves by asking for too little. When Andrew Carnegie sold his steel mills to the J. P. Morgan interests, he asked for $400,000,000. He got his figure, which was higher than Morgan representatives had offered in this deal that resulted in the formation of the great United States Steel Corporation. Later the little old Scotsman was visiting with Morgan on a trans­atlantic voyage and said, "I've often regretted that I didn't ask you for a hundred million more." Morgan nod­ded and said, "If you had asked for it, you would have got it."

There is a charming, white-thatched Manhattan editor named Perry Williams who didn't ask for quite enough and, because of that, very probably sidestepped fame. When he was in his early twenties, Perry wrote a libretto. It was good and many years later was produced in Min­neapolis. But long before that Perry took the positive step of sending the libretto to the world-famous Victor Herbert. If Herbert were interested, that might mean fame and fortune. Word came back that the noted com­poser was very much impressed and would be more than glad to write the music. He would stop in Minneapolis on tour and they would complete arrangements.Perry Williams began living in the clouds. He counted the days until the great Herbert would be in Minneapolis.

Then the composer's plans were suddenly changed. His tour was stopped. "Well, what did you do then?" I asked the man who had opened the door to fame by simply ask­ing for it. "Nothing," said Perry Williams. "I was disap­pointed. But I didn't want to press Victor Herbert." "Couldn't you have hopped to New York to talk it over?" I asked. "After all, he said he was impressed and would be glad to write the music." Perry smiled ruefully, "I could have done just that. But I didn't. I've often wondered. . . ."

His positive attitude had opened the door to fame and left it ajar waiting for him. His negative attitude involv­ing a youthful shyness had slammed shut the door. Perry Williams has had a fine career as a chamber-of-commerce director, writer, and editor, but at twenty-three he hadn't learned the value of a consistently positive attitude in the attainment of desires and he wasn't fully aware of the super four-wheel braking power of the negative attitude.

Is a Cable TV Bundle For You?

Cable TV deals aren't hard to find, that is as long as you aren't already a subscriber to Comcast or Time Warner.

The reason for this is because the cable television guys want to increase their customer base, so of course they are willing to offer you a good deal, usually for the first year of your cable service. The cable company understands if you get service from them, you probably will set up a with one of their triple play bundle that puts all of your services together like voice, video and hi speed internet.

You can almost alway get a triple play bundle for around $100 a month for the first year. Consider what the typical cable TV company charges: Basic TV costs $55 per month, high speed internet is $40 per month, and phone service is $35 per month. With prices like this, your overall bill would be $140 per month plus all of the taxes and charges that find their way onto your cable bill. With prices like this, a promotional deal that offers all three services for $99, even if it is just for 6 months looks pretty good to the average cable TV customer.

But what kind of issues can this lead to? Well consider what the bill will look like once the promo is over. Then you will have all of your TV's hooked up to cable TV, your high speed internet with your e-mail address with the cable company, and of course your home line with the cable company as well. But suddenly your price goes up nearly 45%, from about $100 per month to $145+ every month. Its not alway easy to switch out of your provider?

While you might say to yourself it is not a problem to switch to some kind of deal from Direct Tv or something else from your local phone company like Verizon FiOS. Some things though are easier said than done. Usually the time and inconvenience of switching from cable to satellite TV makes the customer yield to whatever service they have. Even though the monthly bill is high, the subscriber stays with the cable company because they have all the services in a package, making it harder to switch. That is what the cable television company counts on when giving the subscriber a good short term deal.

Choosing A Mobile Phone Plan

Fortunately with so much competition, cell phone plans are abundant, which is good news for owners of cell phones everywhere. Owing to the large number of network services in this country, it may help you to research and assess their offers before deciding on the type of scheme that suits you best.

Of course if you are a heavy user then a monthly cell phone plan may be a better option for you. For self employed individuals or just heavy phone users then the monthly packages that are available are usually the better option to take. Currys mobile phones store provides an excellent outlet for researching for a plan to suit your needs.

Family plans are becoming more popular as are those based on your geographical location. Before you get too excited it is a good idea to check exactly what is included in these agreements.

One downside to prepaid cellular phones is that they often have watered down functionality compared to those that are paid for monthly. Businesses for example would not benefit from the family option.

Of course the biggest benefit a cellular phones that is part of a family plan is that calls made between those family members who are on the same contract usually get a discount. You may also find that other savings are available using this type of plan including special airtime discounts.

Of course national cell phone plans will include free calls anywhere in the country. You will also not be charged for roaming with this type of plan and this is of huge benefit to business travelers.

For regional use free national calls do not apply but you may it is unlikely you will be charged full price for the airtime used. Prepaid cell phone plans are often the preferred type for travelers and business people as the traditional plan without roaming and long-distance charges might be best.

Remember, having a cell phone and being available all the time may not be healthy, thus, you have to be wary not to allow people disturb you when you need to be alone with or without your cell phone.

Definition of Electron Beam Melting versus rapid prototyping.

Prototype

Rapid Prototyping or EBM is a great new alternative method, that can be used instead of both rapid prototyping and manufacturing of metal products. The method is especially useful to the aerospace industry.

The technology is becoming very popular because it has the ability to build dense parts that are similar to any wrought material. Besides, the cost for manufacturing parts through this process is substantially less as compared to the other additive fabrication or metal based methods that are common employed. EBM has also opened the doors to configurations for several new designs.

The technology is very useful as it can help produce parts using titanium within hours as opposed to days. There are a lot of low volume products that can be created here that the aerospace industry enjoys. The time and the cost factors involved in creating titanium products are major obstacles for the aerospace industry. However, with the help of EBM, ready to install titanium parts can be created in an efficient manner.

Working of Rapid Prototyping : Like the name suggests, the Rapid Prototyping device consists of an electron beam that has the ability to melt metal powder. The machine lays down layers of the powder metal successively, after reading data from 3 – D CAD model. The parts of the machines are computer controlled, and it builds the finished model by laying one layer over another, of the metal.

The system consists of beam gun that emits the electrons. There is a tungsten filament that releases a cloud of electron when it incandesces. The electrons that are emitted pass through the gun at around ½ the speed of light. The electron movement is organized and directed with the help of a magnetic field within the system. The magnetic field also acts like a lens and directs the beam in the direction that is desired so that the powder can melt to create an appropriate design. The second magnetic field deflects the beam at the desired point on the target powder.

The metal powder is essential because its only when the electrons hit the mteal powder that the kinetic energy is converted into thermal energy. As a result of which, the temperature is raised above the melting point of the metal powder and the powder liquefies.

In the Electron Beam Melting system, the electron gun remains stationary while there are mechanical parts that move and thus deflect the electron beam so that the metal can be build into a desired shape.

The complete process is carried out in a vacuum so as to avoid any kind of energy loss, which may occur, if the electrons are allowed to collide with gas or air molecules. The system is 95 % efficient when it comes to energy consumption.

Besides, the melted product that is formed is in the pure form and thus there is thermal treatment is not required on the product formed. Another major advantage of using the machine is that it is capable of creating strength to weight components. Besides, with the help of the machine only one component can be created instead of the multi piece components that need to be assembled later.

Definition and how LOM is used in Rapid Prototyping.

Prototyping

Laminated Object Manufacturing or LMO is a system used for rapid prototyping. It consists of adhesive – coated layers of plastic or paper that are stuck together with the help of glue and then cut into an appropriate shape with the help of a laser cutter or a knife.

How does Laminated Object Manufacturing Work? The LMO is used to manufacture 3 – D objects that are cut on the basis of the geometrical data that is available with the system. The laser that is used in the LMO is a carbon dioxide laser that is capable of creating cross sections of 3 – D objects successively, from layers of foil, usually paper. The back of the 3 – D object that is created has a polyethylene coating on it.

The computer with the help of which Rapid Prototyping runs, has the ability to slice a solid 3 – D model into 2 – D cross sections that are thin. Every cross section would have a thickness that is equivalent to the thickness of each of the materials that is used for the process of prototyping.

The system also consists of a rewinding and an unwinding roll. These are connected to each other with the sheet of the material that is being used to manufacture the prototype. The sheet is routed with the help if the idler rollers that are also present in the machine. The rolls are the ones that supply the material to the machine and also store it, if need be.

The laminated part of the prototype is built one a platform that is capable of incremental vertical movement. The movement of the platform is brought about by a stepping motor. On the top of the platform, is a heated roller that can both, heat and compress the stacks of sheets or ribbons that are placed on the lamination platform. The heated roller moves in a reciprocal manner and binds the ribbon material by heating it.

There is also an x-y axis table on the machine that holds and positions the mirrors which do the reflecting of the beam that is emitted by the laser. The table also carries the lens that ultimately focuses the laser beam on the surface of the stack that is laminated so as to cut the top most layer of the stack.

The scrap pieces that are produced as a result of the building process stay on the platform itself. These are basically diced by the beam of the laser into several squares in the cross hatched pattern. The scraps serve as a support for the part. When the built part is removed from the machine, it is in the form of a block. Whats nice is that the cross hatched scrap pieces can be separated fairly easily from the block.

Why Use the Laminated Object Manufacturing? The machine can be used to build larger models for the purpose of sand casting or to understand the conceptual design of something. Even though you can build massive prototypes with Laminated Object Manufacturing, one of its limitations is that you cannot build hollow parts with LOM. Nevertheless, it is relatively less expensive and a much faster way of building robust parts for rapid prototyping.

FDM Prototyping and Fused Deposition Modeling

Prototyping

FDM or Fused Deposition Modeling is said to be one type of a free-form fabrication technologies being developed Stratasys Inc. As this technology utilizes high force ABC plastic it is one of the most preferred technologies for prototyping plastic parts which require force. The Fused Deposition Modeling is a method of layered manufacturing which extrudes a very thin drop of plastic, just one layer at a time. A string of plastic is supplied into an extrusion cranium where this string is heated into a state of semi-liquid form and then extruded via a very tiny passage onto the other layer of the substance. Support substance is even being laid down in the same method. 

How it Works? Prototyping is also said to be a solid based rapid prototype method which extrudes substances to build a model layer by layer. Prototyping is also the second most extensively utilized technology of rapid prototyping after SLA or Stereolithography. Actually, a plastic string is being released from a coil and then provides substances to an extrusion syringe. This syringe is then heated to melt the stored plastic it also has a mechanism that allows the flow of the melted plastic to turn on and off when required. This syringe is later mounted to a mechanical phase that can be shifted both in vertical and horizontal directions.

As the syringe is shifted over the desk in the much needed calculations it drops a thin drop of extruded plastic to create a single layer. This plastic later hardens immediately after being squeezed from the syringe and merges to the lower layer. This complete procedure continues within a chamber that is held at a temperature which is below the plastics melting point.      

Other Substances Included in this Process: Several other substances are also available for this procedure which includes investment casting was and ABS as they offer excellent strength. Most recently, poly (phenyl) sulfone or polycarbonate substances were also introduced that expand the capacities of this method further in terms of temperature and strength. Support construction is being constructed for overhanging geometries and then is detached by breaking it away from those objects. Even a water-soluble support substance that can just be washed away is available these days.

This particular method is quiet easy and office friendly. Rapid Prototyping process is also considered to be rather fast for small parts in the category of a few cubic inches or with those having tall and thin form factors. However, it can even be slow for those parts with wide cross segments. Technology and some elapsed time has really helped improve this method of producting parts. However, they are not quite on average compared to Stereolithography. Three dimensional printing is yet another competitor to the procedure of FDM. Nevertheless, FDM offers wide range and greater strength of substances compared to the implementations of three dimensional products from Z Corporation.       

Advantages and Disadvantages: One of the main advantages of utilizing the method of FDM is the durable parts which can be made by using waxes and few other engineering plastics. One of the main drawbacks of utilizing the method of FDM is that these parts normally take longer time to create and the layering is undoubtedly noticeable because of the process of extrusion.

3D Scanners along with technology for 3D Scanners

3D Scanners

3D scanner: Prototyping implies analyzing the real-world environment or objects for collecting data on their appearance, i.e. color and shape. Digital 3D models can be constructed from the data collected. Such devices are being used by the amusement industry extensively for producing video games and movies. This technology is more widely used in reverse engineering, industrial design, prototyping, keeping records of cultural artifacts, and computer vision. A number of technologies have been used for building the three-dimensional scanning devices. Every technology has limitations, costs, and advantages.

Functionality: The idea behind using a three-dimensional scanner is creating a Point Cloud of the Geometric Samples on the subject’s surface. The subject’s shape can then be extrapolated by using these points. If information regarding color is gathered at every juncture, the determination of colors on subject’s surface can be easily done. There are a lot of similarities of 3D Scanners and Cameras. If one tries to define a Spherical Coordinate System wherein the origin would be the scanner and vector would be drawn from front of it such that θ=0 and ¢=0, then every point in picture would be associated with θ and ¢. Combined with distance that corresponds to r component 3D position of every point in picture is described by the spherical coordinates.

Technology: Prototyping consist of two types- non-contact and contact. There are a few different categories of 3D Sanners and those are passive and active scanners.

Non-Contact Active: There is always some light or radiation that you will find is let through by active scanners. It is advised to detect the reflection of this light, as it would help in locating environment or an object. The kinds of emission possibly used include x-ray, ultrasound, or light.

Contact: Contact three-dimensional scanners locate the subject by the way of physical touch. The best example of contact three-dimensional scanner is a CMM (Coordinate Measuring Machine). It is widely used in manufacturing processes due to its precision. However, it has a disadvantage that contact with object to be scanned is required. The scanning process can potentially modify or damage the target object. Historical artifacts, in particular, have to be specially taken care of.

3D Prototyping: Prototyping is the subset of rapid prototyping. The basic advantage of 3D prototyping is that numerous materials can be used as base materials. It involves taking of virtual designs through CAD (computer-aided design) or Animation Modeling software, transforming them into virtual, thin, and horizontal cross sections, and then creating every cross-section in the physical space, 1 by 1 till the model gets completed.

It should be noted that STL File Format is the interface between machines and CAD software. This interface carries out the approximation of shape of an assembly or part by making use of triangular facets. Surfaces of a superior quality are produced by smaller facets. 3D prototyping is believed to be the ‘next level’ equipment by most of the experts of this field. This technique is trying to be mastered by some of the pioneer companies. The conservative prototyping machines cost around 25000 pounds, as per the study conducted in the year 2005.

Prototyping: What is it and how does Prototyping Work

Prototypes

PCB Prototyping can be defined as the process of constructing physical objects automatically by making use of ‘solid freeform fabrication’. The initial techniques Rapid Prototyping came into being in late 1980s. They were then used for producing prototype parts and models. In today’s world, they are being used for much wider applications. For instance- manufacture of quality parts. Various sculptures who make items to put in fine arts exhibitions sometimes use this technology to make those sculptures we look at today.

Origin: Rapid Prototyping has taken virtual designs through ‘animation modeling software’ or ‘computer aided design (CAD)’. Thereafter, transformation into virtual, thin, horizontal cross-sections takes place. Each cross-section then gets created in the physical space. This process goes on till the model gets completed. It is better known as WYSIWYG process. Let's understand this process in detail.

WYSIWYG: WYSIWYG as the abbreviation for ‘What You See Is What You Get’. It is used in ‘computing’ for describing a system wherein content looks similar to final product at the time of editing. It is generally used in word processors. However, this use is in the form of HTML (Web) authoring. This phrase was made popular by a comedian named Flip Wilson. His character ‘Geraldine’ used to say this very often to give an excuse against her idiosyncratic behavior.

This expression came to be applied later to computer-based applications as practicality in technology arrived. At times, it is phonetically spelt as ‘Wizzywig’ or ‘Wizywig’. It has also been used as a brand name for a ‘lighting design tool’ utilized in theatre industry to pre-visualize the shows and 3D CAD.

The process further : The additional fabrication causes the machine to read data from CAD drawing. After that, consecutive layers of powder, sheet material, or liquid are laid down. Vary Similarly, you can build up a model from a chain of cross sections. Such layers, corresponding to CAD model’s virtual cross section, are then fused automatically or joined together for creating the ultimate shape. The basic advantage of additive fabrication goes to state that any geometric feature or shape can be created through this.

The CAD software and machines are interfaced by the ‘standard data interface’ in the ‘STL file format’. The function of STL file is approximating the shape of an assembly or a part by making use of triangular facets. Surfaces of higher quality are produced by smaller facets.

The word ‘rapid’ can be used relatively. Depending on the models sometimes the construction of these models could take a few hours all the way up to a few days. This depends on the technique used, along with the complexity and size of the model. The additive systems take less time. They can produce models within some hours. Some techniques such as ‘solid freedom fabrication’ make use of two materials for construction of parts. The 1st material is known as ‘part material’ and the 2nd one as ‘support material’. The removal of support material takes place by heat. It might also be dissolved with water or any other solvent. When it comes to manufacture of plastic products, that too in large quantities, injection molding proves to be a cheaper alternative.

SLA Prototyping Process and the process of SLS Prototyping

Rapid Prototyping

Prototyping is a process by which a working model or prototype is developed to test the various design ideas, features, concepts, use, functionality and performance. You can get feedback almost immeditally from the end user and give this to the manufacturer. The technology of rapid prototyping is quite revolutionary and innovative and has found widespread applications in nearly all types of industries. The prototypes can be developed on the basis of past design and its performance and necessary modifications can be made to refine the final product as per the requirements. Rapid Prototyping has manifold advantages like reduction of process cost, time and risks, conceptualizing of the actual product, delivery of high quality product, better communications and so on.

As it is with all the technologies, there are some disadvantages as well associated with rapid prototyping like communication gaps, high expectations of the users which are not fulfilled and so on. Really when you look at it, the benefits outweight all of the disadvantages. There are a host of different rapid prototyping technologies.

Rapid Prototyping Technologies: The numerous rapid prototyping technologies may include the various types like additive, formative or subtractive. Initially, rapid prototyping technologies involved only additive processes. You will see that the major differences between these variou additive technologies is that these layers are build differently between these options for creating parts. Some rapid prototyping technologies melt or soften materials for producing the Layers (FDM, SLS), whereas other technologies lay down liquid material called thermosets and these are later cured by different methods.

The various rapid prototyping technologies are SLA or Stereolithography, SLS or Selective Laser Sintering, LOM or Laminated Object Manufacturing, SGC or Solid Ground Curing, LENS or Laser Engineered Net Shaping, FDM or Fused Deposition Modeling, 3DP or Three Dimensional Printing, Inkjet, EBM or Electron Beam Melting and miscellaneous non-commercialized technologies.

SLA or Steroelithography: The Prototyping technology of SLA or stereolithography provides with the greatest accuracy and gives the best possible surface finish among all the rapid prototyping technologies. This technology uses liquid photopolymer resin that has the property of solidifying on contact with the correct color light. The most commonly used photopolymer materials need UV light, but resins that work in visible light are also used.

SLS or Selective Laser Sintering: SLS or Selective Laser Sintering rapid prototyping technology uses metallic powders or thermoplastics. This technology is quite similar to stereolithography. The finishing time is reduced as the undercuts and overhangs are given support by the solid bed of powder. The surface finishes are not as good as stereolithography. It requires no final curing like SLA, but the object is porous as it is sintered. The mechanical characteristics of the object can be improved by infiltrating the object with some other material as required by the application. Ceramic Tools and Metal Object and the direct fabrication of these things is one area where this method is used.

Prototyping and the Stereo Lithography Processes

Rapid Prototyping

Stereolithography or SLA is one of the most commonly used Prototyping and rapid manufacturing technology for creating several parts with excellent surface finish and high accuracy. Rapid Prototyping is a mechanism used to perform Stereolithography Apparatus. The SLA process has a part where objects are created by a laser beam marking the surface of the photopolymer. This category of substances initially developed for packaging and printing industry, solidifies quickly wherever the laser beam hits. As one layer is being entirely marked out it lowers a small distance into the vat of the liquid photopolymer and a subsequent layer is marked out exactly on the top of the first layer.

The self cementing property of this particular substance causes the layers to merge with one another and finally form an absolute 3D object after lots of similar objects are created. Some of these objects have undercuts or overhangs that must be actually maintained during the procedure of fabrication by maintaining the structures. These structures are automatically or manually designed and later fabricated along with the objects. When the fabrication procedure is completed these objects are elevated from the vat of the liquid photopolymer and then the supports are removed.
      
Stereolithography or SLA is being considered to provide one of the best surface finishes and exact accuracy of any technology of rapid prototyping. In the year 1988 SLA was one of the first rapid prototyping profit making business and thus is thought of as the pinoeer of Rapid Prototyping. This particular system consists of a vat of photo-curable liquid photopolymer, a controlling system and an Ultra Violet Laser Beam. A podium is being lowered into the vat of the liquid photopolymer via the elevator system in such a way that the surface of the podium is the layer-width below the surface of the vat.

This laser beam then marks out the border lines and seals in the 2 dimensional cross segment of the model, hardening the resin anywhere it touches. As the layer is completed the podium sends down layer thickness where the resin flows over the first layer and then another layer is being created. This procedure continues until the entire model is completed. Once the entire model is completed the podium increases the vat and the extra resin is being drained. This completed model is later removed from the podium, washed clearly and then placed in an Ultra Violet oven for ultimate curving. 

For so many years, a wide range of substances with properties intimating those engineering thermoplastics have been created. Restricted selectivity color altering substances for biomedical and additional applications are also available along with ceramic substances which are at present developed in large number. Another thing that is neat about this technology is that it can work on very very large objects.

On the other side, working with liquid substances can be untidy and some parts quite often need a post-curing function in a completely separate Ultra Violet oven or an apparatus for absolute stability and treatment. In recent times, the latest technology of inject has even been extended to operate with photopolymers which result in systems which have both perfect accuracy and quick operation.

Vereconference System Review

I think I have found powerful, easy to use online VoIP conference system. The VereConference system has been specifically designed to meet the needs of major corporations all the way to home based businesses - regardless of what your product is, or what you are promoting. VereConference is a reliable, no nonsense, easy-to-use, 100% web based conferencing service that you can use right NOW... without spending a dime!     

With all the technology that's available today, it's frustrating to continually be disappointed by one VoIP system after another. Most simply don't deliver, or else lack the critical features required to ensure your business will be successful. Others have a quality product, but charge an arm and a leg to use it. VereConference is the best of both worlds: a superior high-end VoIP system that you can use for no cost at all.

You may have tried out some other "web conference" systems and found you had to download and install a piece of "screen sharing software" that may or may not work on your operating system. The to hear what was going on, you had to dial in on a phone line (where you can hear babies crying, fax tones blaring and speaker phones echoing, as you tie up your phone line for a couple of hours and run up your long distance phone bill).

All you need is a computer with an Internet connection of any kind. You can use it to provide live, online support for your existing customers and website visitors. Perform live online training sessions for your team. The whole interface is really neat and easy to use. Just a click of the link and you're in. The sound is good quality, and obviously there's text chat for your guests without a microphone, and private text chat conversations on the side of the main presentation. Also there are keyboard commands for visually impaired users.

Synchronized web browsing allows you to push web pages for 1000's of viewers to see.
The white board will support Frames in webpages. It's all 100% Internet based - no phone line or teleconference needed. You can record meetings - archive and post them on the web. (this requires an upgrade though).
There is unlimited monthly usage, and you can customize the look and feel of your room.
All in all a good bunch of facilities available for free, and the paid extras are very reasonably priced too.
