Toyota Cultivating Engineering Talent

Toyota has a knack for cultivating engineering talent

Toyota now has more than 1,000 York Township employees dedicated to conducting engineering services on vehicles for the North American market. Early on in its expansion project, the Japanese automaker displayed a canny understanding of how to cultivate talent and acquire engineers fresh out of college.

Toyota established a two-year internship program for recent engineering graduates at schools like the University of Michigan, Michigan State University, Lawrence Technological University and the University of Wisconsin. At the end of the two-year period, the automaker and the employee reach a mutual decision about whether the employee should continue working there.

Bruce Brownlee, senior executive administrator for external affairs for the Toyota Planning Center at the Toyota Technical Center, has said the company generated a “large pipeline” for engineering talent by leveraging the internship program.

Computer Chips to Catch Cactus Thieves

Feds to use computer chips to foil cactus thieves

Anyone thinking of swiping a stately saguaro cactus from the desert could soon be hauling off more than just a giant plant. National Park Service officials plan to imbed microchips in Arizona’s signature plant to protect them from thieves who rip them from the desert to sell them to landscapers, nurseries and homeowners.

The primary objective is deterrence, but the chips also will aid in tracking down and identifying stolen saguaros, said Bob Love, chief ranger at southern Arizona’s Saguaro National Park.
…
Saguaros are unique to the Sonoran Desert, 120,000 square miles covering portions of Arizona, California and the northern Mexican states of Baja California and Sonora. They’re majestic giants that can grow to heights of 50 feet, sprout gaggles of arms and weigh several tons. They can take 50 years to flower and 70 years before sprouting an arm.

Holographic Television on the Way

Ok, there really isn’t much new since I posted that holographic TV is getting closer. But won’t it be cool when I can have one in my house? And you might need to plan for it in your new house addition 🙂 Also, with the economic news lately a good distraction might be useful – Holographic television to become reality

The reason for renewed optimism in three-dimensional technology is a breakthrough in rewritable and erasable holographic systems made earlier this year by researchers at the University of Arizona.

Dr Nasser Peyghambarian, chair of photonics and lasers at the university’s Optical Sciences department, told CNN that scientists have broken a barrier by making the first updatable three-dimensional displays with memory.

“This is a prerequisite for any type of moving holographic technology. The way it works presently is not suitable for 3-D images,” he said. The researchers produced displays that can be erased and rewritten in a matter of minutes.
…
According to Peyghambarian, they could be constructed as a screen on the wall (like flat panel displays) that shows 3-D images, with all the image writing lasers behind the wall; or it could be like a horizontal panel on a table with holographic writing apparatus underneath.
…
Peyghambarian is also optimistic that the technology could reach the market within five to ten years. He said progress towards a final product should be made much more quickly now that a rewriting method had been found.

However, it is fair to say not everyone is as positive about this prospect as Peyghambarian. Justin Lawrence, a lecturer in Electronic Engineering at Bangor University in Wales, told CNN that small steps are being made on technology like 3-D holograms, but, he can’t see it being ready for the market in the next ten years.

I would have to say I am with those that think this might take a bit longer to be in place. But I would be glad to be wrong.

Engineer Your Life

Engineer Your Life is an outreach initiative committed to sharing with college-bound young women the opportunities available to them in the world of engineering. Unfortunately they chose to use flash content and the website fails to follow simple usability guidelines (basic stuff like human readable urls, links that work without javascript…) but there is decent content. The use of flash and failing to pay attention to usability are highly correlated in my experience. The site profiles 12 engineers including Judy Lee:

Judy’s enthusiasm paid off. A few months later, the IKEA engineer asked her to design a children’s play mat. Judy was thrilled and soon found herself in IKEA headquarters in Sweden, where she worked with a team of engineers and product developers. It was at this moment that she realized her ideal job was one that truly offered a balance between creativity and problem solving.

Designing for IKEA
Judy began her new project by thinking about the way kids play. “I realized that kids today play indoors a lot. Maybe because the world seems a little more dangerous and parents are more protective. So I knew that this mat had to incorporate some kind of physical play element.” Rather than a static mat, Judy designed one resembling a giant lazy Susan that kids could spin around on. “Once I had the concept, the mechanical engineer in me took over. I needed something simple. Simplicity is awesome. My mat is basically two injection-molded pieces of plastic that spin on a set of interior wheels.”

Judy will never forget the experience of seeing her mat in an IKEA store. “It was incredible,” she recalls, “and it was such important validation for me that my ideas matter, they’re good, and they’re marketable.”

Dream Job at IDEO
Today, Judy has found her dream job in Palo Alto, California, at a company called IDEO, one of the country’s most innovative design firms. IDEO hires engineers, designers, psychologists, and businesspeople who work in teams to develop cutting-edge products (they created Apple Computer’s first mouse, for example). Judy designs children’s toys, pet products, and packaging for over-the-counter drugs and food. “I feel pretty lucky to have such a creative and interesting job. I’m surrounded by brilliant people. It doesn’t really seem like work. It’s just plain fun!”

Engineering a Better World: Bike Corn-Sheller

More appropriate technology from MIT’s D-Lab.

D-Lab-developed device makes corn processing more efficient

Jodie Wu, an MIT senior in mechanical engineering, spent the summer traveling from village to village in Tanzania to introduce a new system for processing the corn: A simple attachment for a bicycle that makes it possible to remove the kernels quickly and efficiently using pedal power. The device makes processing up to 30 times faster and allows one person to complete the job alone in one day.

The basic concept for the maize-sheller was first developed in Guatemala by an NGO called MayaPedal, and then refined by Wu last semester as a class project in D-Lab: Design, a class taught by Department of Mechanical Engineering Senior Lecturer Amy Smith. Now, thanks to Wu’s efforts, the technology is beginning to make its way around the world.
…
Thus, the owner of a bicycle, with a small extra investment, can travel from village to village to carry out a variety of useful tasks. A simple bike thereby becomes an ongoing source of income.

Wu refined the corn-sheller system, which was originally designed as a permanent installation that required a bicycle dedicated solely to that purpose, to make it an add-on, like Kiwia’s tools, that could be easily bolted onto an ordinary bike and removed easily.

Photo shows the prototype of the attachment. Engineering that makes a significant difference in people’s lives (especially those that need it the most) is even cooler than the latest high tech gizmos in my opinion. And those new gizmos are cool.

Carbon Nanotechnology in an 17th Century Damascus Sword

Carbon nanotechnology in an 17th century Damascus sword

Wootz, with its especially high carbon content of about 1.5%, should have been useless for sword-making. Nonetheless, the resulting sabres showed a seemingly impossible combination of hardness and malleability.
…
Amazingly, they found that the steel contained carbon nanotubes, each one just slightly larger than half a nanometre. Ten million could fit side by side on the head of a thumbtack.
…
It isn’t clear how ancient blacksmiths produced these nanotubes, but the researchers believe that the key to this process lay with small traces of metals in the wootz including vanadium, chromium, manganese, cobalt and nickel. Alternating hot and cold phases during manufacture caused these impurities to segregate out into planes. From there, they would have acted as catalysts for the formation of the carbon nanotubes, which in turn would have promoted the formation of the cementite nanowires.
…
By gradually refining their blade-making skills, these blacksmiths of centuries past were using nanotechnology at least 400 years before it became the scientific buzzword of the twenty-first century.

Wind Power Provided Over 1% of Global Electricity in 2007

graph of global installed wind power capacity

Data from World Wind Energy Association, for installed Mega Watts of global wind power capacity in 2007. 19,696 MW of capacity were added in 2007, bringing the total to 93,849 MW. Europe accounts for 61% of installed capacity, Germany accounts for 24% and the USA 18%.

The graph shows the top 10 producers (with the exceptions of Denmark and Portugal) and includes Japan (which is 13th).

The Glove – Engineering Coolness

Cool invention helps tired players bounce back

The device, called the Glove and invented by two Stanford biologists, is used by the Niners during games and at practice for players’ health. But its applications are far broader: from treating stroke and heart attack victims to allowing soldiers to remain in the field longer under intense heat.

It’s also a proven athletic performance enhancer – billed as better than steroids without any ill effects.

“We use the Glove primarily for health reasons,” said Dan Garza, the 49ers’ medical director. “But outside of sports, it has potential for a lot of exciting things. This technology is a much more effective way of cooling the core temperature than what we would typically do – misting, fanning, cold towels, fluids.”

The Glove works by cooling the body from inside out, rather than conventional approaches that cool from outside in. The device creates an airtight seal around the wrist, pulls blood into the palm of the hand and cools it before returning it to the heart and to overheated muscles and organs. The palm is the ideal place for rapid cooling because blood flow increases to the hands (and feet and face) as body temperature rises.

“These are natural mammalian radiators,” said Dennis Grahn, who invented the device with Stanford colleague Craig Heller.

Cool, you can buy your own for only $2,000 🙂 (The Glove used to be called Core Control) High resolution image. Related: Research on Reducing Hamstring Injuries – The Science of the Football Swerve – Randomization in Sports – posts on science and athletics

$12.5 Million NSF For Educating High School Engineering Teachers

$12.5 Million National Science Foundation Grant

The University of Texas at Austin’s Cockrell School of Engineering, College of Natural Sciences and College of Education have been awarded $12.5 million by the National Science Foundation (NSF) to prepare educators to teach engineering to Texas high-school students.

The UTeachEngineering program targets future and current teachers, providing multiple avenues to prepare them to teach high school engineering. University faculty will use half of the five-year grant funding for course development, lab development and salaries. The other half of the grant will provide stipends, scholarships and fellowships to students and teachers working toward engineering teaching certification.

Current teachers will benefit from two curricula developed through the grant: a six-week Engineering Summer Institute for Teachers and a UTeach Master of Arts in Science and Engineering Education, which takes place over three summers. The curriculum for prospective teachers will target undergraduate students in engineering and the natural sciences, and lead to a bachelor’s degree in a scientific or engineering field as well as dual teaching certification in science and engineering. Addressing the need for trained engineering teachers is especially crucial in Texas because of a new law that requires high school graduates starting in 2011 to complete four years of science. One year can be a course in engineering.
