Copy of Canadian Technological Advancements
Transcript of Copy of Canadian Technological Advancements
Henry Lam The 1960's The 1980's That is how The Canadian Technological Advances are historically significant to Canada Introduction The 1960's was a revolutionary period for the film industry
The cinema attendance heavily increased and along with the boom came several innovations in cinematic projector designs and picture frames
A group of Canadian film makers invented the IMAX projection system after increasing difficulty with the installation of the multi-screen projectors at Expo 67, held in Montreal
In late August, the first IMAX projector was built at McMaster University, Ontario in a private engineering faculty that supported private industry (which was later installed at Ontario Place in 1971)
The newly invented IMAX projector consists of a single screen and runs the 15/70 mm film horizontally fed which increased the visual impact of the film and also produces a widened image for better resolution and very crisp, detailed images
In addition, the IMAX camera is also used partially to shoot films in high definition and in the recent past, 3D or Three Dimensional Background info
Throughout the 1990s Canadians made one more step closer to technological advancement when Canadian inventor and electrical engineer Dr. Brent Townshend created a core concept in 1996 that served as the basis for what is known as the 56K bit/sec modem .
A groundbreaking and critical appliance that for the first time allowed data transfer between two computers at high speed .
As we all know there are several types of modems used to communicate, using telephone and without, but this was a unique invention as it was a Canadian who found the 56k modem and one of the fastest ways to communicate and share data within computers overseas and domestic.
Dr. Brent Townshend was a Canadian who was born in 1960. He has earned his PhD in electrical engineering from the stand ford university in 1987 with expertise in a single processing, computer design and statically modeling. Worked as a principal for bell labs from 1987-1990 where he studied speech recognition. Who was Dr. Brent Townshend? In 1993 he moved to Townshend computers tools and began working on Music Fax appliance for downloading from servers via direct-dial telephone connections . Townshend developed an algorithm that enabled 56K downloads from the Internet over standard analog dial-up phone line connections.
This represented a 66 percent improvement over previously existing modems' performance .
His technology allowed for this to occur only in the download direction, which eliminated cumbersome analog-to-digital conversions and kept speed consistent. How Dr. Brent came up with the idea of the 56k modem and how did it affect rest of the world.
When was the invention successful?
The year 1996 changed the view of global communication as Dr. Brent Townshend invented the 56k modem and made it easy to transfer files through computers faster . The 56k modem is the 3rd fastest DSL modem . The 1970's An Introduction Technology plays a vital role in our urban society; precisely, demand and reliance on these mechanisms grow daily. Throughout history, Canada’s existence shows proof of their contribution to scientific developments through progressive technical inventions that benefit citizens on a global scale. Our Decades I. 1960- The IMAX Projector
II. 1970- The Electric Prosthetic Arm
III. 1980- The Canadarm
IV. 1990- The 56K Modem Ever been to the movies? No, I'm not talking about this movie. I'm talking about this. The Canadarm was created by SPAR Aerospace Ltd, in cooperation with CAE electronics, NASA and the NRCC (National Research Council of Canada). The arm was designed in the early 70s and production upon it began in the 1980s. By 1981 the Canadarm was ready to be launched with its first mission, aboard the Columbia space shuttle. Lets Look at the Arm! The Arm in Action! Why the Canadarm?
What is the importance of this invention? NASA ordered Canada to make this arm, leading to a major Canadian contribution in the area of space. NASA was at the leading edge in the 1980s and when they approached Canada for their contribution we were honored to do our part. Canada's contribution not only benefited the country itself but it also helped on a global scale. Once completed the Canadarm became one of the most relied upon invention for missions in space. Whether, something had to be deployed from the loading bay of the shuttle or something need to be fixed or set up in space the Canadarm could do it all. The Reason behind the invention of the IMAX Projector and its significance? After WWII, the young population was booming (baby boomers, 1945-1960) and along with them, they brought a high cinematic “craze”
To compensate for the large viewing audience, these few young inventors went a step further than conventional 35mm to a single, large-screen projector which can project crisp images and increased the aspect ratio from 4:3 to 16:9, greatly enhancing the resolution
The significance of the invention of the IMAX Projector at Canadian hands resulted in great appreciation for the Canadian Film Industry and also influenced many American filmmakers to adapt to the IMAX camera and globally revolutionized the film industry and the experience viewers received while watching films projected by the IMAX projector. History of Prosthesis
-Prosthesis originated from the Greek word prósthesis (Addition or attachment)
-Prosthetic limbs were commonly developed globally in ancient times.
-Ancient Greek and Egyptians took a liking to this matter and crafted countless different variations of prosthetic, although every single one was stationary and immobile.
-The earliest semi-mobile prosthetic was developed in 1898 by Dr.Vanghetti. He illustrated the prosthetic’s mobility through muscle contraction.
-In 1971 the first Electric Prosthetic hand was developed beginning a new revolution prosthetics. Impact of the invention of the IMAX Projector on Canadian Society and its people The invention of the IMAX Projector meant a great deal for movie fanatics and caused the cinema attendance rates to sky rocket
People now had the ability to view movies in thrilling clarity; the colour contrast was magnificent, a great step up from the gray scale projectors 10 years ago
Since the IMAX was a canadian invention, it made Canadians feel welcomed and proud due to this advanced development
This added yet another prominent leisure activity for Canadians and eventually, the whole world, especially the United States of America which improved relations
What is the Electric Prosthetic Hand? Significance of the Electric Prosthetic hand What is the Electric Prosthetic Hand?
Who: This invention was crafted by the Canadian medical scientist, Helmut Lucas.
What: The Electric Prosthetic Hand is a metallic hand replacement.
Where: Crafted and developed in Canada
When: The invention was finished in 1971
Why: The Electrical prosthetic hand was developed for medical purposes, giving physical opportunities to those who lost organic limbs.
-Unlike all the previous prosthesis, this is the first artificial limb that is capable of moving in demand of the user.
How: For movement it is required that cables are to be placed on joints of the arm, such as the elbow or shoulder. Therefore, small movements in those areas can govern the grip and finger movement in the electric prosthetic hand.
-Allows handicapped individuals to be physically on par with organically intact people.
-Minimizes the amount of cancer caused deaths
-Initiation of the idea to utilize electricity in prosthetic development began a new revolution of prosthesis. At the present time humans are able to develop artificial limbs that are guided through mental thoughts.
-At the present time, these metallic limbs are seen to be physically more capable in terms of strength and durability than an organic limb. The Electric Prosthetic Hand Conclusion The most valuable invention of the 60's in Canada was the IMAX Projector, without a doubt
Due to the invention of the IMAX Projector, Canada gained a huge amount of attention and was now recognized as one of the leading countries in the film industry
The four men wanted to make the IMAX the most sophisticated, yet the most prevalent projector system used in the world, and they quite achieved that
Since the theater could now project large, more wider and crisper images, more and more people could be seated greatly reducing the need of running multiple films a day, saving on electricity
Finally, this made a night out with friends not only very exciting and entertaining, but also very convenient
