MIT Students Improve Labeling Options for Visually Impared

A team of students from MIT are making the lives of the visually impaired easier with a project inspired by their course work last fall. The battery-operated 6dot Braille Labeler uses standard Dymo label tape and hopes to provide those in need of the product with a cheaper, portable alternative to other more costly options.

The 6dot’s developers aim to improve upon the everyday frustrations of those who are visually impaired by making the identification of “seemingly similar” household items such as DVD’s, CD’s and canned foods easier.

According to a press release issued by MIT, “Blind people really wanted to see this product on the market,” Karina Pikhart, Class of 2009, said.

Development of the 6dot escalated after students from MIT’s Product Engineering Processes course won a $7,500 cash prize at last spring’s IDEAS competition.

“We worked really closely with blind people” in developing it, she says, because “you really can’t develop a product without being in close touch with the people you’re developing it for.”

According to MIT, the company created by the students involved in the project does not plan on manufacturing the device but will continue to improve the system while waiting to get the 6dot licensed within the next two years.

“The goal is to get it into the hands of as many people as possible,” Pikhart said. “We’re … looking for a manufacturer who would take this on for the long haul. We want to keep improving it.”


Improving Earthquake-Resistant Structures

A team of researchers from Stanford University and the University of Illinois have designed a new structural system that allows a building to be more earthquake-resistant.

When a quake strikes, the new system dissipates energy through steel frames in the building’s core and exterior. These frames are free to rock up and down within fittings fixed at their bases. Steel tendons made from twisted steel cables run the length of each frame, keeping the frames from moving so much that the building could shear. When the quake stops, these tensile tendons pull the frames back down into the “shoes” at their bases, returning the building to its plumb, upright position.

Greg Deirlein, professor of civil and environmental engineering at Stanford University and team lead of the project, explains, “This new structural system has the potential to make buildings far more damage resistant and easier to repair, so people could reoccupy buildings a lot faster after a major earthquake than they can now… What is unique about these frames is that, unlike conventional systems, they actually rock off their foundation under large earthquakes.”

The technology, which just completed testing at Japan’s Hyogo Earthquake Engineering Research Center, is the culmination of more than a decade of ideas and previous-gen technologies. While many elements of the system have been tested before, this is the first time they’ve been melded into a complete system and successfully put through the motions. For testing, the team constructed a three-quarters-size model of a standard three-story office building, with a footprint 120 by 180 feet, and a mass comparable to a full-size building. Then they shook the hell out of it. Even at a magnitude 1.75 times that of the 1994 Northridge earthquake — itself a 6.7 on the Richter scale — the only damage recorded in the frame was in the replaceable fuses.

U.S. Government Takes First Step to a National High-Speed Rail System

“US government to announce high-speed rail subsidies”

The US government will begin announcing subsidies for high-speed rail projects, part of the economic stimulus package, in late September, a US official said Monday.

“We expect the first grant announcements will be made in late September, early October,” Mark Paustenbach, a spokesman for the Department of Transportation, told AFP.

The department announced in mid-July that it had been swamped with proposals from state and local governments seeking financing for high-speed rail systems.

The 787-billion-dollar stimulus package of President Barack Obama’s administration passed in February allocates eight billion dollars to high-speed rail. More than one billion dollars a year are budgeted over five years.

The Obama administration says the grants are the first step toward building a high-speed rail system nationally.

The United States currently lags far behind rail transport systems in Japan, France, Germany and China.
