A Short History of Bluetooth

If you own a smartphone, tablet, laptop, speakers or any of the array of electronic devices on the market today, theres a good chance that, at some point, youve paired at least a couple of them together. And while virtually all our personal devices these days are equipped with Bluetooth technology, few people actually know how it got there. The Somewhat Dark Backstory Strangely enough, Hollywood and World War II played a pivotal role in the creation of not only Bluetooth, but a multitude of wireless technologies. It all began in 1937 when Hedy Lamarr, an Austrian-born actress, left her marriage to an arms dealer with ties to Nazis and fascist Italian dictator Benito Mussolini and fled to Hollywood in hopes of becoming a star. With the support of Metro-Goldwyn-Mayer studio head Louis B. Mayer,  who promoted her to audiences as the worlds most beautiful woman, Lamarr notched roles in films such as Boom Town starring Clark Gable and Spencer Tracy, Ziegfeld Girl starring Judy Garland, and 1949 hit Samson and Delilah.   Somehow she also found time to do some inventing on the side. Using her drafting table, she experimented with concepts that included a reworked stoplight design and a fizzy instant drink that came in tablet form. Although none of them panned out, it was her collaboration with composer George Antheil on an innovative guidance system for torpedoes that set her on a course to change the world. Drawing on what she learned about weapons systems while she was married, the two used paper player piano rolls to generate radio frequencies that hopped around as a way to prevent the enemy from jamming the signal. Initially, the U.S. Navy was reluctant to implement Lamarr and Antheil’s spread-spectrum radio technology, but would later deploy the system to relay information about the position of enemy submarines to military aircraft flying overhead.   Today, Wi-Fi and Bluetooth are two variations of spread-spectrum radio. Bluetooth’s Swedish Origins So who invented Bluetooth? The short answer is Swedish telecommunications company Ericsson. The team effort began in 1989 when the Chief Technology Officer of Ericsson Mobile, Nils Rydbeck, together with a physician named Johan Ullman, commissioned engineers Jaap Haartsen and Sven Mattisson to come up with an optimal short-link radio technology standard for transmitting signals between personal computers to wireless headsets that they were planning to bring to the market. In 1990,  Jaap Haartsen was nominated by the  European Patent Office for the European Inventor Award.   The name Bluetooth is an anglicized translation of Danish King Harald Blà ¥tands surname. During the 10th century, the second King of Denmark was famous in Scandinavian lore for uniting the peoples of Denmark and Norway. In creating the Bluetooth standard, the inventors felt that they were, in effect, doing something similar in uniting the PC and cellular industries. Thus the name stuck. The logo is a viking inscription, known as a bind rune, that merges the kings two initials.  Ã‚  Ã‚   Lack of Competition Given its ubiquity, some may also wonder why there arent any alternatives. The answer to this is a little more complicated. The beauty of Bluetooth technology is that it allows up to eight devices to be paired together via short-range radio signals that form a network, with each device functioning as a component of a larger system. To achieve this, Bluetooth-enabled devices must communicate using network protocols under a uniform specification. As a technology standard, similar to Wi-Fi , Bluetooths isnt tied to any product but is implemented by the Bluetooth Special Interest Group, a committee charged with revising the standards as well as licensing the technology and trademarks to manufacturers. For instance, Bluetooth 4.2 (released in 2014) uses less power and features improved speeds and security compared to previous versions. It also allows for internet protocol connectivity so that smart devices can be linked.   That isn’t to say, however, that Bluetooth doesn’t have any competitors. ZigBee, a wireless standard overseen by the ZigBee Alliance was rolled out in 2005 and allows for transmissions over longer distances, up to 100 meters, while using less power. A year later, the Bluetooth Special Interest Group introduced Bluetooth low energy, aimed at reducing power consumption by putting the connection into sleep mode whenever it detected inactivity.

Adam and Eve - Short Essay free essay sample

At first glance this fresco does not look very dramatic. Adam and Eve are tempted and make the mistake that costs them Eden. However, we need to think of what exactly was lost. In Catholic theology, the time before the fall was also a time of peace, happiness, without sickness or even death. God created man in Gods own image (Gen. 1:27). We clearly suffer now; we are prone to illness; we age; we die. The God of goodness did not create us to exist in this state, so how could it happen? We did it to ourselves. On one side of the image, there is a richer green. There are the leaves of the tree. On the other side, the land is flat, barren, more like a savanna. Eve is reclining on the Eden side, to indicate the rest and the lack of any need that was present in paradise. We will write a custom essay sample on Adam and Eve Short Essay or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page On the other side, both are walking, to signify their lack of rest or ease. They are both cowering down and look to have aged a great deal. Before the fall, notice how Eve looks healthy, beautiful and intelligent. Contrast how she looks after she is expelled from Eden, aging, unwell, and frightened. Her arms cover her breasts out deep emotion, and perhaps shame. On the side before the fall, Adam looks young and fit. Adam would not age until the fall; it is a consequence of original sin. Also, notice how the angel doesnt just threaten with the sword. Adam cannot go back, not with the angels sword on the back of his neck. There is deadly purpose here. Adams hands appear to be warding off the angel, surrendering, saying that he is going. I would consider the Bible a complex network of myths, very few of the stories in the Bible can be scientifically proven and the book itself is very complex and the stories are very intricate as if they were imaginary. The Bible if probably one of the most if not the most culturally important book in the world. This story in particular, the expulsion from the Garden of Eden conveys political and moral values of our culture; the loss of grace through original sin and its consequence. The invention of superhuman entities is clearly visible in this fresco; the serpent and the angel are both superhuman. The Bible is also filled with rituals, ceremonies, and dramas. The expulsion from the Garden of Eden is most definitely a drama.
