Answer by mallimalar_2000
(m) Bar codes were invented by Bernard Silver and Norman Woodland in 1948. Their system used light to read a set of concentric circles, but they had to wait two decades before the advent of computers and lasers made their system practical. (However, the bar code system in use today is the Universal Product Code, introduced by IBM in 1973. The first bar coded item sold was a pack of gum in 1974.)

This is an episode of REVOLUTIONARIES, a co-production of the Computer History Museum and KQED television, with major sponsorship by Intel. Recorded: January 27, 2011, originally broadcast on April 2, 2012 One night in the late 1930s, in a bar on the Illinois-Iowa border, John Vincent Atanasoff, a professor of physics at Iowa State University, after a frustrating day performing tedious mathematical calculations in his lab, hit on the idea that the binary number system and electronic switches, combined with an array of capacitors on a moving drum to serve as memory, could yield a computing machine that would make his life and the lives of other similarly burdened scientists easier. Then he went back and built the machine. It worked. The whole world changed. Why don't we know the name of John Atanasoff as well as we know those of Alan Turing and John von Neumann? Atanasoff never secured a patent for his early device, and a number of the concepts he pioneered were incorporated into the breakthrough ENIAC computer that evolved into the legendary UNIVAC. But in 1973 a court declared that the patent on that Sperry Rand device was invalid, opening the intellectual property gates to the computer revolution. Join Pulitzer Prize winning novelist Jane Smiley in a conversation with the Computer History Museum's John Hollar about the fascinating man who beat the world's greatest minds in the quest to develop the first true digital computing machine.

Who invented the cell phone? After World War two the cell phone invention was credited by an engineer of the world- famous Motorola cell phone company, and his name is Dr. Martin Cooper. The son of a Ukrainian descendan, and now a world renounced name, Dr. Cooper received a bachelor's degree in electrical engineering from Illinois Institute of Technology. In 1954 he started working for Motorola and at night he studied to get his master's degree. In 1957 he finally graduated with a master's degree.

In 1950, John F. Mitchell also graduated in electrical engineering, and in 1960 he became the chief engineer of Motorola Mobile Communications Projects. Together they became the cell phone invention pioneers. Cooper worked hard in developing the first portable handheld police radio, it was developed in 1967 for the Chicago Police Department. Back then it was all analog, not till recently with the new digital radios now becoming more and more popular.

In 1973 the c reation of the first portable cellular 800 (MHZ) phone was now yearning in its prototype. At the time Motorola's base station was trying to get clearance from the FCC. With cell phones you need frequencies in order to send information over the air. FCC (Federal Communications Commission) they are in charge of all radio signals and frequencies that are sent out over the air. They play a vital role in today's society. Have you ever wondered why you have to turn off your phone on a plane prior to take-off? The reason is because the signals from your phone can interrupt the signals of the planes electronics in which are relayed back to the tower on the air-strip. Remember to always turn off your phone before boarding a plane.

The first cellular phone call was demonstrated in New York on April 3, 1973 near the New York Hilton hotel. Reporters flocked to the scene, the media wanted to know who invented the cell phone. What better place to make history. Especially, in the mid dle of the most populated city in the US. The name of the phone is called a Dyna-Tac handheld cellular phone 800 X, it weighed a whopping 2.5 lb (1.1 kg). At the time only military and big business had access to them.

Dr. Joel S. Engel head of research at Bell Labs was his rival at the time. Both companies were working neck and neck with each other, when the public would ask; "who invented the cell phone" they both wanted to say I did. Guess who received that first cellular phone call? You guessed it Bell Labs! It kind of reminds me of Steve Jobs with Apple Computer and Bill Gates with Microsoft Windows. Both companies are strong competitors in today's markets; you can find them both on the New York Stock Exchange.

Fundamental technology and communication markets had shifted from clunky cell phone invention efforts, to state-of-the-art personal handheld mobile devices. Coopers invention stream-lined from making phones for automobiles to personal handhelds. Having a computer integrated in a phone today to check your e-mails, among other fascinating features isn't uncommon.

For the price of $ 4,000 dollars a phone they were not cheap, by a long shot. By the time Motorola started selling phones to consumers, he decided to leave the company and start his own business. If a successful business of cellular operations couldn't be enough, with his personal success and fortune Dr. Cooper decides to sell his niche, for a phenomenal $ 23 million dollars to Cincinnati Bell. They are in the New York Stock Exchange and thriving with their symbol as (CBB).

In 1987 Dr. Martin Cooper and his wife Arlene Harris started working on a few technological endeavors from cell phone invention to large companies such as SOS Wireless, Array-Comm to Jitter-bug.

To sum it up, I guess a little of Captain Kirk from the hit series Star Trek inspired his efforts in the development of invented cell phone technology, to the latest cell phone inve ntion of the century.
