The right atrium pumps oxygen-depleted blood from the body into the right vesicle, which transports it into the lungs. The left atrium pumps aerated blood from the lungs into the left vesicle, which transports it into the body.The first machines that were considered an artificial heart were machines that kept the blood pumping while the heart was being operated on. The first artificial heart, for human use, was implanted in 1969. The artificial hearts are made of metal, plastic, ceramic, and animal parts. You would think that an artificial heart would take a long time to make. It only takes a couple days to put together and test. They are made in a clean room to avoid contamination. Each heart consists of up to 50 components. Solar Cell 1954 Chaplin,Fuller, and Pearson came up with the idea of making silicon the main energy conductor for the solar cells. They made the first solar cell and it was able to produce enough energy, from the light, to power several devices. The first solar cell only had 6% efficacy and were produced from Bell Laboratories. Hydrogen Bomb 1951 There are two ingredients in a hydrogen bomb; Deuterium and Tritium. Both are infused into helium, which releases energy. This weapon is very dangerous but nobody ever knows how it will react. There is no limit to its destruction.
Three men opposed the creation of the hydrogen bomb; J. Robert Oppenheimer, Enrico Fermi, and I.I. Rabi. Fermi and Rabi wrote "Since no limit exists to the destructiveness of the weapon, its existence and knowledge of its construction is a danger to humanity as a whole." The first hydrogen bomb was tested in 1952, and its code name was "Mike" It weighted 80 tons and was 21 feet high. Bravo, the second hydrogen bomb that was tested, was dropped in 1953. Some men were on a boat, far enough from where the bomb was dropped, and everyone on the crew fell ill. One man then eventually died from the radiation of the bomb. Then people concluded that a nuclear war could and would lead the end of the world. http://www.atomicacrchive.com/History/coldwar/page04.shtml

http://www.madehow.com/Volume-6/Artificial-Heart.html Bar code scanning emerged in the late 1096's as a way to improve the accuracy of data entry into the computers. There are many different kinds of bar-code scanners but they all use the same principles. They use the intense red light to reflect off the white and black stripes. That tells the computer what to do. The challenge was to find a quick, efficient, and fool-proof method. There are some criteria that must be met by all manufacturers. They include; First Pass Read Rate-The percentage of time that a code can be read the first time it passes the scan window. Rejection Rate-The number of scans per million that simply wont be read. Read Velocity- The range of speeds with which a code may be passes over the surface of a scanner. 1960-1969 ATM In 1960 a bank, New York's First National City Bank, installed a bankograph. The bankograph was a way for customers to pay utility bills and get a reciept without having to see a teller.
In 1967 a cash dispenser was installed to a bank in London called Barclays Bank. It was made my De La Rue Instruments.
In 1968 Barclays and a few other banks introduced a machine that encoded cash on a plastic card. You could purchase them from the teller. The downfall to this product was that the machine "ate" the card so if you wanted another one, you would have to go buy another one.
In 1969 New York's Chemical Bank received a Docuteller machine. The Docuteller machine was the first ATM to use magstripe cards. 1975 1979 Cell Phone The first cellular network was launched in Japan in 1979. The inventor of the first hand held
cell phone was Martin Cooper.
The first phone weighted 2 pounds and sold for about $3,995. It makes our phones we buy now-a-days seem cheap. It was called "The Brick." From the day of thought to the day of mass production and shipping it took 10 years for "The Brick" to become a part of society. 1979 The Walkman The Walkman, or the "Sound-about" and "Stowaway" as called in the UK, debuted on July 1st, 1979. It was first released in Japan, where it was a huge hit! Sony, the main inventor of the portable music device, thought that it would only sell 5,000 units per month. In the first two months, it sold 50,000. In the Walkman's life time it sold a cumulative 200 million units. It weighted 14 ounces and was blue and silver. It also had two earphone jacks so two people could listen at once. Not many of our music players have that! 1988 Doppler Radar Doppler, an Australian physicist in 1842 who described how the frequency of light and sound was affected by the relative motion of the source or detector. This came to be known as the Doppler affect. A Doppler radar is used to predict the weathers movement and intensity. When the source of the waves approaches the radar, the frequency of the waves increases. While, during the regression of the source of the waves, the frequency of the waves decreases. 2001 Apple's iPod The first generation iPod was publicly announced on October 23, 2001. It had an easy to use scroll wheel along with a center select button, and 4 aux buttons around the wheel. 2003 Toyota's Hybrid Car In 1994, the Vice President of the Toyota company gave the engineers a challenge; to double the fuel efficiency of a normal car. The team told them that it would completely impossible to to build that. In 2000 the first Prius was invented. It was the first car to have better gas mileage then any other car on the market. 2011 Light Field Camera, Lytro The Lytro camera lets you create living pictures that you can endlessly refocus after you take them. Taking a picture with the Lytro camera only involves putting something in the foreground and finding something interesting in the background. The camera has an aluminum body with a rubber grip. On the rubber grip it has a shutter button, and a zoom slide. It also has a touch screen that allows you to focus anywhere on the picture, even after you take it! The camera may be little but the price sure isn't! They start at $399 http://solartribune.com/history-of-photovoltaics/

So nobody knew of a laser printer until IBM introduced it in 1975. Technically IBM was the first to invent the laser printer because it was the first one mass produced. Laser Printer
