Application of Reverse Engineering in Computer Aided Designing

had been around for decades, but it was not until the 1920’s that scientists perfected the advanced technology. Many inventors came into play when it came to the various systems used to create the first T.V., but no one is to be named the “inventor.” Scientists spent decades trying to find a breakthrough, and it was not until the 21th century that it was found. Charles Francis Jenkin’s system helped lead to the first construction of the T.V. He had demonstrated a scanning system with a revolving disk, he called it “radio vision.” Jenkins system worked but the images were blurry. Another inventor named Herbert E. Ives invented his own system called the “185 line system.” Philo Taylor Farnsworth was another key inventor. In 1927, he developed the “image dissector.” This was the first ever working electronic camera tube. Philo was motivated by his system and continued trying. His hard work led him to invent the first fully electronic T.V. system. A radio corporation named the RCA, was very intrigued by his work and sent their own engineer to Philo’s lab. This engineer perfected Philo’s “iconoscope;” a camera tube ("History of Television”). After this perfection of the T.V., the United States of America was changed forever. Soon after, there was a rapid growth in technology. The T.V. brought entertainment and opened peoples eyes to the good and bad parts of American culture, through the images and movies shown on the screen. Today, over 238 million T.V.’s

In 1884 the first ideas of the television came to an inventor by the name of Paul Nipkow. It was called the scanning disk and was patented by him in 1884. It worked by having a large disk spin in front of an object, while the photoelectric cell that worked it would take in the changes

The beginning of TV can be tracked back to the discovery of photoconductivity back in 1873 by Willoughby Smith. TV was invented in the mid 1920’s by a Scottish inventor name John Logie Baird in London. Baird patented technology by using arrays of transparent rods to transmit images to be delivered to a television set. The first picture of moving object was transmitted by Baird in 1924, televised human face in 1925, and last but not least the first real – time moving object in 1926. The first color broadcasting was arrived in United States in 1953 and the first color commercial was televised in 1954 and soon television became the leading source for national advertising. Television was first demonstrated in 1939 at New York

Humans are pattern seeking animals and we are adept to finding patterns whether they exist or not. Our entire world is created or represented by patterns which either naturally exist or are man-made, however, if these patterns are not actually there, a pattern can be created. Even our daily lives in society is a pattern, a continuous routine of the same day-to-day events. Patterns allow comfort in the unknown, when something is able to be labeled or expressed with a formula, it is able to be explained. Humans seek patterns in the real world based off of various ways of knowing, which includes reason, perception and emotion. These different ways of knowing are explored and used within different areas of knowing, such as mathematics, natural

4. Mechanical dissection is beneficial when you want to learn how objects and mechanisms were made and how they work. This what engineers do they use mechanical dissection to find how machines work and how they were made and it helps you to improve the object or mechanism because mechanical dissection includes observation and documentation. In conclusion, mechanical dissection helps you learn about the parts of the machine and how they work together.

[f] I used the backward design model to approach the learning unit because I looked at it from a top-down perspective. That is, first, I decided which big picture I would choose. Following that, I chose three subjects that I believe could best reinforce this big picture and teach it. I chose English, art and Social Science because I felt that these three interrelated. I then chose the content descriptors that I felt would fit in best with the 3 learning areas. The content descriptors were chosen with the idea of oppression and TSI rights and culture in mind; that is, they are focused not only on knowledge but also on meaningful examination, research and artistic skill. I chose to include art in my unit because I feel that when students express

In many jurisdictions, copyright laws foster interoperability, either by allowing for a specific reverse engineering exception to owners’ exclusive rights or by giving wide fair-dealing measures. As the reverse engineering exception commonly operates, firm A may design a new product compatible with an existing product controlled by software owned by B, by first copying B’s program in object or machine code form in order to understand how it works and what is required for it to interact with other software. A will then not infringe B’s copyright provided no substantial amount of B’s program is copied.

Around 1930, it was seen that mechanical television would never be able to produce a proper quality which could be used for commercials and other programs. An electronic television needs a picture tube this allowed to display the picture and an electronic camera tube was needed in order to capture the image. Philo Farnsworth, produced images on his image dissector camera tube in 1927. However, the image dissector required too much light to be practical for television.

The majority of my teaching career has been spent a public school that firmly believes in Jay McTighe’s backwards design model. At the beginning of the school year, my colleagues and I would explore our content standards, determine power standards, and create essential questions that would drive our units. We would plan our lesson around the skill students should know at the end of the unit and plan assessments that would test students’ knowledge. There was never any discussion on how we would differentiate these lessons for students. One thing that I have learned from Carol Ann Tomlinson and Jay McTighe is that differentiation and backwards design should work in tandem to provide “powerful knowledge that works for each student” (Tomlinson & McTighe, 2006, p. 3). In a conversation with both experts I would discuss the learning I have gained as a result of studying their work.

A world without knowing what is happening is an unknown world. Hundreds of years before, people were living not perceiving the happenings all over the globe. It is indeed a very disturbing thing that turns people to be innocent or unconscious of the real world. However, through a great and brilliant Canadian mind, television is finally invented. Reginald Fessenden, a Quebec-born inventor, was one of the many discoverers who invented television. In fact, the first television set in North America was patented by him in the year 1919 (www.connectedrogersca). With over 500 patents to his name, including pioneering breakthroughs in sonar and radio, Fessenden came up with this ground-breaking idea by lying on the carpet with a cat on his chest (www.connectedrogersca). Clive James once said, “Anyone afraid of what he thinks television does to the world is probably just afraid of the world” (www.famous-quotes.com). According to that, Clive portrays television as a powerful key to unraveling the secrets of the entire nation - either negative or positive. Although viewers have access to a plethora of both appropriate and inapplicable TV content, television’s positive impacts to the world are more prevalent. Indeed, through this breakthrough invention, television serves as an education tool for children, a guiding voice to people, a revelator of new ideas and information, and most notably, a means of
