Inventors Of The Cell Phone

A cell phone also known by its popular terms as mobile phone, cell or handphone is an electronic device that uses a full duplex two way radio telecommunication over a cellular network. Using popular terms we could describe the cell phone as an object that allows two ore more persons to communicate over a large area of distance.

The inventor of the cell phone was Martin Cooper, an researcher and executive at Motorola. He successfully made the first call using a hand held phone , now known as a cell phone on April 3rd 1973, The person whom he called was no randomer, it was his own rival Dr. Joel S. Engel, a researcher at Bell Labs. The constant race between the two rivals made this innovation to come this early, back in the days. Of course, the hand held phones back then were not as delightfull as they are now, heavily weighting and big sizes was a big burden for any user. In time the sizes and the weight of the cell phones, decreased considerably up to a feather like object with the help of new technology and being able to pack an increasingly number of transistors on a smaller and smaller integrated chip. Along with this new innovation a new secondary market beginned also. Embedded gadgets for the phones added the spicy looks and increased their capabilities and features, being able to perform as a video/photo camera also or radio and even as a gaming platform, increasing its popularity amongst teenagers.

For the constant busy man the arrival of this device was a blessing and came at the right time. The market for this luxury item at beginning had well over 12 millions clients in 1990, by the end of 2009 the number of subscriptions went to a staggering 4.5 billion, thats 300 times the number back then.


The first 1G commercially automated cellular network generation was lunched in Japan by Nippon Telegraph and Telephone Corporation or NTT in 1979, initially only covering only the metropolitan area of Tokyo, 5 years later NTT expanded the network to cover the entire population becoming the first 1G nation network. The first modern 2G technology network appeared in Finland in 1991 and it was lunched by Radiolinja now part of Elisa Group. The third generation or 3G was again lunched in Japan. The profits from this new technology were exceeding billions of dollars, thus making the number of people investing in it to increase at a fast rate. The constant pump of money in researching, in the technology of manufacturing mobile phones, leaded to its big success and helped this once luxury item now common one, to become popular amongst us. With no doubt the inventors of the cell phone had one of the biggest impact in our modern day society, allowing us to communicate with each other faster then any other technology. If there is any item out there that most of us could not perform our daily tasks, we could easily say that its the cell phone, picturing a world without this piece of technology is harder then anyone could believe.

History Of The Digital Camera

A digital camera which is also known as a digicam or by its popular term cam, is an electronic device that takes videos and/or phothos by recording the images using an electronic image sensor and stores the data on a micro card storage device unlike its predecessor that used film to store the videos or photos. Almost all the digital cameras that are currently being used can record sounds, moving videos and still photos at the same time. It may be a common and popular gadget nowadays but it has not been always like this.

The history of the digital camera dates back in 1960s when the television technology, computer progress and space exploration registered a blooming success. The modern digital camera technology is directly linked and related to the technology that was used for recording television.


history-of-the-digital-camera

Television, video cameras and digital cameras uses a charged coupled device also known as CCD to sense the light color and its intensity while recording. The CCD came along with the help of the first video tape recorder invented in 1951 and later researched in the Bing Crosby laboratories perfecting the system and responding to the needs with an improved version of it. At the same time the National Aeronautics and Space Administration - NASA, upgraded their system that was used to explore and map the surface of the moon from using analog signals to digital signals . Since computer technology was advancing very fast, NASA was able to enhance the images and the videos that the space probes were sending with the help of the new and more powerfull computers. The are huge differences between the digital cameras and the film cameras. One of the advantages that comes along with it is that once you filmed something or taken a photo, you can immediately have a look at it, or edit it, while the older technology cannot provide such a feature. The lack of the magnetic band needed to store the informations is also a big benefit for everyone and made this gizmo popular amongst us.

Digital cameras can also be embedded on other devices such as mobile phones or newer and cooler PDAs. Even the Hubble Space Telescope itself is just a digital camera only built for certain specifications and needs, thus you can say that the telescope is just a specialized digital camera. The digital cameras are made in a wide range of sizes, prices and capabilities. Amateurs and professional photographers use bigger and more expensive digital cameras known as digital single-lens reflex camera for their capabilities and features, being more versatile then the ordinary ones. We can say that in the history of the digital camera, 21st century is the time when this gadget became available for everyone to buy, making it one of the most popular electronic device. Everyday there are newer and better digital cameras being presented to the market, and its highly possible that by the time you finished reading this article a new improved model already came out.




Martin Cooper, the inventor of the cell phone

The man who invented the first portable handset is considered to be Martin Cooper. His carreer started at Teletype, a subsidiary of Western Electric. He was hired by Motorola in 1954. Cooper cooperated fixing a defect in the quartz crystals Motorola made for its radios. Cooper focused his work on the development of portable products. This includes the first handheld police radios, built for the Chicago police department in 1967. At the beginning of the ‘70s, Cooper was charged to lead Motorola’s cellular research. That is when Cooper had his vision of mobile phones used everywhere, and not only in cars.

Thanks to Cooper's passionate research, the invention of the first handheld cell phone lasted only 90 days in 1973, when first portable cellular 800 MHz phone prototype was created. After doing some testing in Washington, Cooper and Motorola presented their new technology in New York, in order to demonstrate to reporters and the public how it works. The first call Cooper ever made was to his rival, Bell Labs head of research, Joel Engel. Cooper made the phone call from a prototype Dyna-Tac handheld cellular phone before going to a press conference upstairs in the hotel. On April 3, 1973, standing on Sixth Avenue in New York City, Cooper was connected through this phone call with the station of the Burlington House (which is now the Alliance Capital Building) across the street. This date goes into history as being the day when the first phone call made from a portable handset.

This first phone to be produced weighed about 2.5 lb. Cooper declared that the invention of the cell phone was inspired by watching Captain Kirk using his communicator on the television show Star Trek. Cooper wanted to prove that the cell phone could function as a resourceful part of the telephone network. Therefore, after demonstrating the way the protoype works to reporters, Cooper allowed some of them to make some phone calls. The original Motorola DynaTAC handset, weighed 2.2 pounds and had 35 minutes of talk time. Cooper has stated that “The battery lifetime was 20 minutes, but that wasn't really a big problem because you couldn't hold that phone up for that long.” By 1983 and after four trials, Cooper’s team had reduced the handset’s weight by half. The list price was around $4,000. Cooper left Motorola before they started selling handheld mobile phones to consumers.

In 1995, Cooper obtained the Wharton Infosys Business Transformation Award for the technological innovations he made in the communication field. Besides this, Cooper is also a member of Mensa. In 2009, Cooper received also the Prince of Asturias Award for scientific and technical research. In February 2010, Cooper was selected to the National Academy of Engineering.
