      Really good information and details on what happened while Nils Bohlin was inventing the three-point seat belt.
  • Bohlin aimed to find an alternative design that would not only protect both the upper and lower body, but would also be comfortable and simple to use.
  • The design held both the upper and lower body in place, and was simple enough that the driver could buckle up with one hand.
  • In 1958, Bohlin was h
  • by 1963 all Volvos came equipped with front seat belts, and the company decided to make the design free for use by all car makers.
  • In 1959, Volvo became the first auto maker to introduce Bohlin’s three-point safety belt design.
  • The report claimed that the belt had already saved thousands of lives, reducing the risk of injury or death in car accidents by as much as 75 percent.
  • It persuaded a number of other national governments to do the same
  • Since its introduction, the three-point shoulder/lap safety belt has changed very little in its overall design.
  • As of today, the U.S. National Highway Traffic Safety Administration estimates the belts reduce the risk of deaths in car crashes by at least 45 percent.
  • Bohlin retired from Volvo in 1985.
  • In 1974 Bohlin was awarded The Ralph H. Isbrandt Automotive Safety Engineering Award.
  • honored in 1979 and in 1985 by the National Highway Traffic Safety Administration in Washington, D.C. In 1995, he received a medal from the Royal Swedish Academy of Engineering Sciences. In 2002, he was inducted into the (U.S.) National Inventors Hall of Fame. On the day he was to be honored for this achievement, Bohlin died at age 82.

How a Pop-Bottle Invention Resulted in the Cell Phone | Martin Cooper | Big Think - 0 views

  • For 100 years, people who wanted to talk to other people were wired to their homes, they were latched – or chained to their desks and really didn’t have much in the way of freedom. That we were, in fact, giving people communications in their vehicles: even then, it’s not much better than being tied to your desk. You’re still trapped in your car. So we found out from people, like the Superintendent of Police in Chicago, who told us that he had a real problem. His officers had to be in communication, the only way they could talk was to be in their cars, and yet the people they were protecting were walking on the streets. He asked us, “How can I have my officers connected and still mingling with the people?” And we discovered this was true of people managing airports, people managing businesses, real estate people. So, we became aware of the fact that real communications is portable communications. Put the device on the person. 
  • I was four years old, lived in Winnipeg, Canada, where it’s very cold in the winter and very hot in the summer. And I look at these boys with a magnifying glass. And they were burning a piece of paper by focusing the rays of the sun onto this paper through a magnifying glass. And I just had to know how that worked. And so I did the obvious thing, I took a soda pop bottle and broke it and tried to make a magnifying glass out of it. And that’s when I realize now, that I had discovered that I was going to be an engineer because I want to know how everything works and I always have. 
  • When I was nine years old, I invented—at least I think I invented—a train that could travel through a tunnel from one end of the country to the other. And what was unique about this train was two things. I had learned about friction, and so we had to get rid of friction. And so I thought, why don’t we support this train on a magnetic field? Because I knew two magnets, when they are close together, force themselves apart. And the second thing is if we’re going to get rid of all friction, we have to get rid of the air. So, this train traveled in a tunnel that was totally evacuated. It was in a vacuum. And amazingly enough, they are just starting to build trains like that, maybe without the vacuum, but with magnetic levitation. So, maybe it wasn’t such a dumb idea after all.

  • Science has been a part of my life from the time I was four years old... just knowing how things work, having a curiosity. And my curiosity has been limitless and that’s quite a handicap because there are times in your life when you have to specialize. But I literally want to know everything and only in recent years have I finally realized that I’m never going to know everything. In fact, the older I get, and the more stupid I find out that I am. But science, the understanding of how things work, what things are, has been crucially important to me. So, I started out with fantasy; I’ve always loved science fiction. I’ve always known that I was going to be an engineer, so I went to a technical high school so that I could take every kind of shop and learn how to work with my hands, learned about materials, and I always knew that I was going to go to an engineering school and get an engineering degree. 
  • Science can be interesting. Science can be fun. If, in fact, teachers learn how to present science in that way and learn how to make people curious and make it enjoyable, I think more people will get involved. But it’s not important that everybody become a scientist. Everybody doesn’t have to be a mathematician. Make it interesting enough so the people that have that interest, that have that talent do latch onto the wonderful world that will open up if they dig into science and mathematics. The teaching of science, mathematics, of anything—there really is no difference from a game. If you make a game dull, if you make it uninteresting, if you don’t have something that grabs people... then they won’t get interested and they’ll go do something else. So, I don’t see why teaching should be any different than creating games. Creating a curriculum ought to be the same as creating a game. Make it interesting, make it fun, make it a challenge; all of those things. All of the attributes of playing a game are the things that draw people into learning and I think that’s what we ought to do. We ought to somehow coalesce the concept of teaching with the concept of game playing, and we’re going to find that a lot more of our youngsters are going to get interested in learning and specifically about science, mathematics, technology.

Martin Cooper (American engineer) -- Encyclopedia Britannica - 0 views

  • Martin Cooper, byname Marty Cooper   (born December 26, 1928, Chicago, Illinois, U.S.), American engineer who led the team that in 1972–73 built the first mobile cell phone and made the first cell-phone call. He is widely regarded as the father of the cellular phone.
  • He joined the U.S. Navy and served during the Korean War. After the war, he joined the Teletype Corporation, and in 1954 he began working at Motorola.
  • On April 3, 1973, Cooper introduced the DynaTAC phone at a press conference in New York City. To make sure that it worked before the press conference, he placed the first public cell-phone call, to engineer Joel Engel, head of AT&T’s rival project, and gloated that he was calling from a portable cellular phone.
  • ...2 more annotations...
  • At Motorola, Cooper worked on many projects involving wireless communications, such as the first radio-controlled traffic-light system, which he patented in 1960, and the first handheld police radios, which were introduced in 1967. He later served as a vice president and director of research and development (1978–83) for the company.
  • In 1986 he and his partners sold CBSI to Cincinnati Bell for $23 million, and he and his wife, Arlene Harris, founded Dyna, LLC. Dyna served as a central organization from which they launched other companies, such as ArrayComm (1996), which developed software for wireless systems, and GreatCall (2006), which provided wireless service for the Jitterbug, a cell phone with simple features meant for the elderly.

  • The Puget Sound Engineering Council selected Russell as the 2005 Industry Engineer of the Year. And despite all of his accomplishments, it wasn't until Joe Decuir of Seattle's chapter of the Institute of Electrical and Electronics Engineers, Inc., (IEEE) saw a story about Russell in the local newspaper that he suggested Russell's name to the committee last fall.
  • In the mid 1950s, he was frustrated with the sound quality of LPs, which started wearing out after only a dozen plays. He even tried using a cactus needle to play records because the jewel needle wore out the vinyl faster and didn't sound as clear. Russell wanted a way to capture the complexity and nuances of classical music without damaging the recording. And the idea that sparked a multi-billion dollar industry was about to take shape in Russell's mind.
  • In fifth grade, he started building radios out of parts he scrounged from the neighbors. In high school, he took a job setting up a commercial radio station, even though he didn't know how to hook up most of the equipment. "But I learned– rapidly,” he laughs.

  • After graduating from Reed College with a degree in physics in 1953, Russell took a job with General Electric in the Hanford Nuclear Plant doing experimental work.
  • Battelle took over the Hanford Laboratories in 1965 and gave Russell a lab and time to work on some of his imaginings, including the crazy idea that sound could be converted to strings of numbers and reproduced using light.
  • He had come up with a way of using a laser to read digital bits of information, which later became the most widely-used way to read just about everything. By using a light to read the data, the record would never wear out. The data are encoded as microscopic pit marks on the surface of the disk, which, when spun, can be read to reproduce high-quality sound.
  • The original goal was to record television shows, not music, because adding visuals would be more difficult. If television couldn't be recorded digitally, Russell and his backers decided they would at least know where they stood. In 1973, they were successful, but they were ahead of their time. Amazingly, no one wanted to buy a license for the precursor to the DVD.
  • By 1991, about 25 years after he came up with the idea, CDs were outselling their predecessors, audio tapes, in record stores nationwide.
  • But all he can do is shrug ruefully, "I didn't invent the CD, I invented the technology.”
  • Today, Russell has more than 50 patents to his name. He continues his work from the basement of his Bellevue home where he and Barbara have lived for more than a decade.
  • The first devices were called Optical Digital Data Storage –the term CD is actually a trademark of Philips. The original storage units were made of glass plates, about the size of large index cards, which could be read as a laser scanned over them.

Post-It Notes Were Invented By Accident - 1 views

  • There were actually two accidents that lead to the invention of the Post-It note.  The first was by Spencer Silver.  According to the former Vice President of Technical Operations for 3M Geoff Nicholson (now retired), in 1968, Silver was working at 3M trying to create super strong adhesives for use in the aerospace industry in building planes.  Instead of a super strong adhesive, though, he accidentally managed to create an incredibly weak, pressure sensitive adhesive agent called Acrylate Copolymer Microspheres.
  • It did have two interesting features, though.  The first is that, when stuck to a surface, it can be peeled away without leaving any residue. 
  • Specifically, the acrylic spheres only stick well to surfaces where they are tangent to the surface, thus allowing weak enough adhesion to be able to be peeled easily.  The second big feature is that the adhesive is re-usable, thanks to the fact that the spheres are incredibly strong and resist breaking, dissolving, or melting.   Despite these two notable features, no one, not even Silver himself, could think up a good marketable use for it.  Thus, even with Silver promoting it for five years straight to various 3M employees, the adhesive was more or less shelved. Finally, in 1973, when Geoff Nicholson was made products laboratory manager at 3M, Silver approached him immediately with the adhesive and gave him samples to play with. 
  • ...15 more annotations...
  • Silver also suggested what he saw as his best idea for what to use the adhesive for, making a bulletin board with the adhesive sprayed on it.  One could then stick pieces of paper to the bulletin board without tacks, tape, or the like.  The paper could subsequently be easily removed without any residue being left on the sheets.  While this was a decent idea, it wasn’t seen as potentially profitable enough as annual bulletin board sales are fairly low.
  • Now enter the second accident by chemical engineer Art Fry.  Besides working at 3M as a Product Development Engineer and being familiar with Silver’s adhesive thanks to attending one of Silver’s seminars on the low-tack adhesive, he also sung in a church choir in St. Paul, Minnesota.
  • One little problem he continually had to deal with was accidentally losing his song page markers in his hymn book while singing, with them falling out of the hymnal.  From this, he eventually had the stroke of genius to use some of Silver’s adhesive to help keep the slips of paper in the hymnal.
  • Fry then suggested to Nicholson and Silver that they were using the adhesive backwards.  Instead of sticking the adhesive to the bulletin board, they should “put it on a piece of paper and then we can stick it to anything.”
  • This initially proved easier said than done, in terms of practical application.  It was easy enough to get the adhesive on the paper, but the early prototypes had the problem that the adhesive would often detach from the paper and stay on the object the paper was stuck to, or, at least, leave some of the adhesive behind in this way.  There was no such problem with the bulletin boards Silver had made because he had specifically made them so that the adhesive would bond better with the board than the paper. Two other 3M employees now entered the scene, Roger Merrill and Henry Courtney.  The two were tasked with coming up with a coating that could be put on the paper to make the adhesive stay bonded to it and not be left behind on whatever the paper was stuck to when it was removed, a task at which they were ultimately successful at achieving. Interestingly, because management at 3M still didn’t think the product would be commercially successful, they more or less shelved it for three years, even though the Post-It notes were extremely popular internally at 3M labs during that span.    Finally, in 1977, 3M began running test sale runs of the Post-It note, then called “Press ‘n Peel”, in a certain areas in four different cities to see if people would buy and use the product.  It turned out, no one much did, which confirmed in the minds of the executives that it wasn’t a good commercial product.
  • Luckily for offices the world over, Nicholson and Joe Ramey, Nicholson’s boss, didn’t feel like giving up yet.  They felt the marketing department had dropped the ball in that they hadn’t given businesses and people samples of the product to use to let them see for themselves how useful the notes could be.  So a year after the initial flop, 3M tried again to introduce the Post-It note to the world, this time giving huge amounts of free sample Post-It note pads away in Boise, Idaho, with the campaign deemed “The Boise Blitz”. 
  • This time, the re-order rate went from almost nothing, in the previous attempt, to 90% of the people and businesses that had received the free samples.  For reference, this was double the best initial rate 3M had ever seen for any other product they’d introduced.  Two years later, the Post-It note was released throughout the United States.
  • So after 5 years of constant rejection for the adhesive and another seven years in development and initial rejection, Post-It notes were finally a hit and have since become a mainstay in offices the world over, today being one of the top five best selling office supply products in the world.
  • Ever wonder why the standard color for Post-It notes is yellow?  It turns out this was kind of an accident as well.  The official story from some at 3M is that it was because it created a “good emotional connection with users” and that it would “contrast well stuck to white paper”.  However, according to Geoff Nicholson there was no such thought given to the color.  The real reason Post-It notes were yellow was simply because the lab next door to where they were working on the Post-It note “had some scrap yellow paper – that’s why they were yellow; and when we went back and said ‘hey guys, you got any more scrap yellow paper?’ they said ‘you want any more go buy it yourself’, and that’s what we did, and that’s why they were yellow. To me it was another one of those incredible accidents. It was not thought out; nobody said they’d better be yellow rather than white because they would blend in – it was a pure accident.”
  • Another obstacle in the initial launch of Post-It notes was that, because it was a completely new type of product, it required the construction of new machinery to mass produce the Post-It note pads, which was initially prohibitively expensive for a product seen by many within 3M as destined for commercial failure.
  • While most Post-It notes only have a thin strip of adhesive, you can buy Post-It notes that are completely covered in the back with the adhesive.  One example of a place this type of note is used is at the U.S. postal service.  These full adhesive backed notes are used there on forwarded mail.
  • Post-It notes received an upgrade in 2003 when 3M launched a new version of the Post-It note with super sticky glue that has better adhesion to vertical surfaces.
  • Spencer Silver holds a total of 22 patents, including the patent for the “low-tack, reusable, pressure sensitive adhesive” used in Post-It notes (Patent#: 3,691,140).  Silver is still working at 3M today in their special adhesives department.  He also has a doctorate in organic chemistry, which he received two years before inventing the adhesive used in Post-It notes.  On the side, his favorite past time is painting using pastels and oils, which he apparently is extremely accomplished at.
  •  Post-It notes are occasionally used in art-work.  One such famous example was in 2008 when Shay Hovell used 12,000 Post-It notes to create a replica of the Mona Lisa.  The most expensive Post-It note art piece was done by R.B. Kitaj and sold for £640 (about $1000) in 2000.
  • Art Fry received his early education in a one room schoolhouse.  He studied chemistry at the University of Minnesota and was hired while still in school at the “Minnesota Mining and Manufacturing Company”, which later was re-named 3M.  He retired from 3M in the early 1990s.

Inventor Of Cell Phone: 'We Are Just Getting Started' | Here & Now - 0 views

  • Forty years ago this month, Motorola engineer Martin Cooper changed the world by making the world’s first cell phone call. He stood on a New York City street on April 3, 1973, with a 10-inch-long, 2.5-pound phone nicknamed “the brick” and called his engineering nemesis at the much bigger Bell Labs.
  • Cooper’s latest product, which he created with his wife Arlene Harris, is an ultra-simple phone for seniors called the Jitterbug. “I hate the concept of trying to build a universal device that does all things for all people, because then it doesn’t do any of them very well,” Cooper said. “I think what is going to happen in the future is more customization, more personalization. We all are different and we ought to be able to customize and have a phone that does exactly what we want it to do – that is so easy to use that we don’t even have to think about it. That’s what the dream is.”

Martin Cooper, Father of the Cellular Phone | High Tech History - 0 views

  • Martin Cooper, who turns 82 on December 26th, is an electrical engineer – having gained his Master’s degree from the Illinois Institute of Technology in 1957.
  • Cooper’s inspiration for undertaking the project was the Star Trek television series, in which a small, hand-held ”communicator” device was used very much in the manner of a portable phone.
  • As I walked down the street while talking on the phone, sophisticated New Yorkers gaped at the sight of someone actually moving around while making a phone call. Remember that in 1973 there weren’t cordless telephones, let alone cellular phones. I made numerous calls, including one where I crossed the street while talking to a New York radio reporter – probably one of the more dangerous things I have ever done in my life.

  • Interestingly, the first person he called was Joel Engel, his chief rival at AT&T’s Bell Labs, to tell him he was calling on a portable phone.
  • The original phone weighed a gargantuan 30 ounces, and was referred to as the “Brick.”
  • With nearly four decades of success in the telecommunications industry, Cooper’s guiding philosophy is to look to its bright future: It’s very exciting to be a part of a movement toward making broadband available to people with the same freedom to be anywhere that they have for voice communications today. People rely heavily on the Internet for their work, entertainment, and communication, but they need to be unleashed.

Life-Cycle Studies: Post-it Notes | Worldwatch Institute - 0 views

  • They began in 1980, when a St. Paul, Minnesota, choir member's hymnal bookmarks kept falling to the floor. Chorist Arthur Fry, an engineer at chemical company 3M, joined forces with 3M scientist Spencer Silver, inventor of a peculiar adhesive that stuck poorly to surfaces. The glue provided perfect temporary fixes for paper scraps such as hymnal bookmarks
  • One year after 3M officially launched the Post-it Note, the packs of sticky paper raked in more than US$2 million in sales. Post-it Notes - available in 27 sizes, 57 colors, and 20 fragrances
  • In the 1940s, a Belgian chemist mixed carbolic acid and formaldehyde to create the first synthetic adhesive. Post-it Notes use a more recent innovation: Unlike the typical, featureless adhesive surface, the Post-it Note glue coats the notes with bumpy microspheres that limit the sticky area. The adhesive mostly consists of alkyl acrylate, a volatile liquid that dissolves slightly in water and completely in alcohol. More detailed ingredients remain private. The paper used to make Post-it Notes is certified by the Sustainable Forestry Initiative, a system founded by the U.S. paper industry. Although SFI certification ensures that a company has an environmental management system in place, most environmental groups prefer the international non-profit Forest Stewardship Council's more stringent performance-based environmental and social indicators.

  • By 1908, he developed the first machine for the manufacture of transparent sheets of regenerated cellulose. By 1912, Brandenberger was making a saleable thin flexible film used in gas masks.
  • In 1917 Brandenberger assigned his patents to La Cellophane Societe Anonyme and joined that organization.
  • In the manufacturing process, an alkaline solution of cellulose fibres (usually wood or cotton) known as viscose is extruded through a narrow slit into an acid bath. The acid regenerates the cellulose, forming a film. Further treatment, such as washing and bleaching, yields cellophane.

How Are Adhesive Sticky Note Pads and Cubes Made/Printed? - Quality Logo Products, Inc. - 0 views

  • Sticky notes are much more than simple notepads! If used correctly, they can be ultimate portable marketing tools. Sticky notes were originally marketed to workplaces, but they can now be found everywhere. At home, they come in handy for grocery lists, phone numbers, to-do lists, and reminders. They’re used in magazine advertising to highlight a new product’s advantages; if the reader desires, he or she can peel away the sticky note and take the ad. They also make great bookmarks for students! Sticky notes' functionality leads users to wonder how these little unassuming notes came about and how they are made.
  • Up to that point, 3M had only ever produced rolled products like adhesive tape, so the company’s engineers had to create and build new machinery to accommodate the flat pads and eventually cubes of paper. Then they had to find a way to apply the adhesive without gumming up the machinery. While this was a very expensive venture, it also gave 3M market dominance because few companies had the budget to back such an undertaking.
  • Fry was a member of his church’s choir and often marked pages in his hymnal with bits of paper that almost always fell out. What if he could stick the bits of paper to the pages of the hymnal without damaging the book? Dr. Silver’s glue seemed to be the answer!
  • ...3 more annotations...
  • The idea for sticky notes originated by accident. Dr. Spencer Silver, a Senior Scientist in the 3M Corporation’s Research Lab, discovered a repositionable adhesive in 1968. It hadn’t been his goal to do so, because at the time 3M’s philosophy was "the stickier the better.
