If we talk about the technologies, nowadays any involved technologies. from waking up, we see an electronic clock, phone,etc. until we go back to sleep any technologies involved. Then we went to school, college or workplace is definitely in there we will find technologies. whether it's computers, the time of presentation. This time I will not discuss about what technology we will use in the future or the latest technology made by a company. I will discuss about the ancestors of the mobile phone.
What year was roughly a mobile phone that was first invented? Wasaround 1910 that the embryo of a mobile phone found by LarsMagnus Ericsson is the strongest evidence. Lars Magnus Ericssonis the founder of the telecommunications business we shall know asEricsson. In 1921 the first time Detroit Michigan Police Departmentuses a mobile phone. At that time nearly any the police cars are equipped with communications equipment that allows monitoring ofthe movement apparatus. Operating systems using frequencies below 2 MHz.
In 1960, at a company called Fennis Finnish Cable Works originallyin the field of cable business, do ekspensi and established electronics division. Two years later Bjorn Westerlund, the president of the company that developed the radio transmission business. But only a year later, the field of telecommunications overhauled to strengthen the ranks of electronic business. And in 1967,enterprising Westerlund who later founded the company we are familiar with the name of Nokia.
It took about 50 years to seek innovation and found the finding. Thentransformed into a mobile telephone equipment for people whohave high mobility. The era of the 1970s, Nokia and Ericsson in Europe was transformed into a large telecommunications company.In America, Motorola was trying to compete. Ericsson is currently designing the phones are small dimension. That way, people are more easy to carry, unlike the old phone is great in size. Analogsystem was replaced with digital. And in the 1980's and then slidethe new system which we call the GSM.
And what about the touch screen? In 1971, the first time? Touch Sensor? It was developed by Doctor Sam Hurst (founder Elographics) as well as an instructor at the University of Kentucky.These sensors are called?? Elograph,? and has been patented by the University of Kentucky Research Foundation. ? Elograph? This is not transparent like modern touchscreens, however elograph has become a significant milestone in touchscreen technology. In 1974 The real first touchscreen equipped with transparent surfaces was developed by Doctor Sam Hurst and Elographics. In 1977 Elographics developed and patented by a five-wire resistive technology, which is the most popular touchscreen technology used today.
Touchscreens eventually become commonplace in everyday life.The company uses a touch screen kiosk system in the regulation of retail sales and tourism, sales center, ATM, and PDAs, where the stylus is sometimes used to manipulate the GUI and to enter data.Popularity of smart phones, PDAs, portable game consoles and various types of information appliances has boosted demand and acceptance of touchscreens.
HP-150 from 1983 has been one of the earliest computers in the world of commercial touchscreen. Does not have a touchscreen in a narrow sense, but it has a CRT tube Sony 9 "surrounded by infrared transmitters and receivers, which detect the position of each non-transparent objects on the screen.
Originally the original touchscreens could only sense one point of contact at a time, and have little ability to sense how hard one's touch. Has now begun to change with the commercialization of multi-touch technology.Tablet PC initiated by apple computer and followed by the famous brands of the world has made multi-touch touchscreen becomes the primary interface with a variety of capabilities that it provides.
If you do not want to say about hanging out, then buy touchsreen orsmartphone. Because it would not be denied that the future oftomorrow we will be faced with a super-sophisticated technology.tomorrow may be small even with the features we just give a namewe can call or send sms.
