The REGISSÖR line’s new assembly technique also eliminates the bag of hardware that usually accompanies Ikea’s furniture, and completely removes the risk of there being a screw or a piece of dowel missing, leaving you stranded in the middle of the included assembly manual.
When available later this month the REGISSÖR line will include a bookshelf, cabinets, and a coffee table, and if the new assembly approach proves popular with customers, it will be extended to other products as well—just don’t expect to find it on pieces designed to support a human’s weight, or those requiring extra reinforcement.
Nike Launches Self-lacing Sneakers
Many of us have wished for a shoe that automatically ties its laces when they get untied while we are running. American sports footwear and apparel brand Nike apparently heard us and on Thursday released the futuristic self-lacing sneakers.
Launched at an event here, the shoes — named HyperAdapt 1.0 — resemble the sneakers that Hollywood actor Michael J. Fox wore in the 1989 movie ‘Back to the Future 2’.
Put the sneaker on and it will tighten to the size of your foot using a heel sensor, Quartz reported.
According to Nike, the real innovation is that you can quickly adapt your sneaker to the changes your foot undergoes when competing, using buttons on the side that let you tweak the fit.
Laces, by contrast, may loosen up, or be tied too tight. Your foot may also change shape during exercise (expanding slightly, for instance). The HyperAdapt is meant to eliminate those problems, the report said.
Right now, an athlete has to make those changes manually but this new product has a goal that can make those changes automatically and create a “nearly symbiotic relationship between the foot and shoe”, the company said.
The shoe has a sole that lights up — maybe to make it look futuristic — and it makes a slight mechanical wheezing noise when it tightens.
The report pointed out that the sneaker, which runs on a battery that can keep a charge for about two weeks, has been in the works for around 10 years.
The HyperAdapt 1.0 uses two recent Nike innovations, its Flywire filaments and Flyweave fabric, both of which make the shoes hold more firmly to the foot during sports.
The HyperAdapt 1.0 will be available in three colours and expected to be released by the end of this year.
At the moment, the shoe will be available only to members of Nike+, the new app that Nike wants to be a sort of one-stop-shop for athletes.
MIT develop new imaging system with ‘loose’ fibres
Washington, Feb 14 (IANS) Researchers, including an Indian-origin scientist, from the MIT Media Lab have developed a new imaging device that consists of a loose bundle of optical fibres with no need for lenses or a protective housing.
For medical applications, where the diameter of the bundle — and thus the number of fibers — needs to be low, the quality of the image could be improved through the use of interferometric methods.
The fibres are connected to an array of photosensors at one end and the other ends can be left to wave free so they could pass individually through micrometer-scale gaps in a porous membrane, to image whatever is on the other side.
Bundles of the fibres can be fed through pipes and immersed in fluids – to image oil fields, aquifers or plumbing without risking damage to watertight housings.
And tight bundles of the fibres could yield endoscopes with narrower diametres, since they would require no additional electronics.
“Previous works have used time of flight to extract depth information. But in this work, I was proposing to use time of flight to enable a new interface for imaging,” explained Barmak Heshmat, a postdoc at MIT Media Lab.
Heshmat is first author on the paper, joined by associate professor of media arts and sciences Ramesh Raskar and Ik Hyun Lee, a fellow postdoc.
The researchers reported the results in the journal Nature Scientific Reports.
New LED light bulb technology which can fight jet lag and help to keep the children calm
Advances in LED lighting and neuroscience have led to light bulbs that can mimic natural sunlight and boost our well-being.
By: Joseph Hall – Toronto star
Almost any white LED light you’ve ever seen was an optical ruse.
That white bulb on a Christmas tree? It’s actually a shining blue diode with a touch of glowing yellow on its tip, says Venkat Venkataramanan, a University of Toronto physicist.
“Yellow and blue (are) complementary colours in the light spectrum,” Venkataramanan says. “When you see them together, your eyes trick you into imagining it’s white light.”
But these days, that old trick is far from the only one scientists working with LED lights have up their sleeves. The coming magic centres on manipulating those lights to better your body and mind.
Indeed, the explosion in LED (light-emitting diode) technology over the past decade coincided with new and expanding neurological insights into the ways light affects our mood, our sleep — our physical well-being.
These discoveries have moved the spotlight on LED technologies away from their immense durability and energy advantages.
Scientists are learning how to manipulate LED lights to tune our biological clocks. They’re seeking to use the lights on long-distance flights to combat jet lag, and in schools to help calm children.
The promise the bulbs hold to improve physical and psychological well-being excites LED researchers like Venkataramanan, scientific director at the U of T’s Institute for Optical Sciences.
It didn’t begin well for LEDs in that regard. Many of us were introduced to them that one December back when we first replaced our vibrant — though fickle and dangerously hot — incandescent Christmas tree bulbs with a string of safe but anemic LED lights.
Those sterile, joyless bulbs were based on the high-intensity blue diode that won its three Japanese developers — Isamu Akasaki, Hiroshi Amano and Shuji Nakamura — the Nobel Prize in physics.
But blue, even in a white disguise, is a cold light. It itches at the brain, which has evolved over eons to crave the rich, full-spectrum radiance of the sun.
So the first order of business was to make a sunnier LED light.
This has largely been achieved by combining various photon-shifting phosphors with the standard blue diode and manipulating the gallium nitrate semiconductor at the blue light’s baseto create a wider range of colours.
Tunable diodes that naturally emit the warmer reds and oranges of the spectrum were also introduced into the mix.
Combining all of these advances in multi-diode packages, new-generation “bulbs” have been created to produce a light much more comforting to the eye.
“Now you can put together various different types of LEDs and create an artificial light source that almost resembles sun,” Venkataramanan says.
But it turns out the visual quality of light was only half the story.
Traditionally, it was thought that light entering the eyes hits only two sets of receptors: the familiar rods and cones that discern its intensity and colour respectively.
“But about 10 years back or so they found out that there are also non-visual pathways of light through (the) eyes,” Venkataramanan says.
These non-visual pathways, he says, take in the spectral quality and fluctuations of light as well. But crucially, they also trigger the production of two key hormones that help control the rhythms of the body and brain.
“One (hormone) is melatonin … which sets your circadian rhythm or biorhythm,” Venkataramanan says. While it helps regulate many bodily functions, melatonin is crucial in promoting rest and sleep, he says.
The other light-activated substance is the stress hormone cortisol, which promotes alertness and is critical for daytime performance.
The body’s daily production of these two competing hormones has been tuned by evolution to the natural cycles of the sun.
And because LED lights can so readily change their intensity and spectral quality, they can be used to help reset our sun-tuned biological clocks — clocks that are perpetually disrupted by the artificial lighting, screen time and plane travel of the modern world.
To this end, Venkataramanan is working with the Zhejiang University in China to create LED lighting that can mimic sunlight.
“We have daylight sensors outside, and take that sensor input to tune the spectrum of light” inside, he says. “So exactly the kind of light that you would get outside is what you would get inside. There are a lot of health benefits (to) being in the natural sunlight cycle and darkness cycle as well.”
Venkataramanan works with chemists, engineers, physicists, psychologists and neurologists in his U of T research. His lab also works closely with the burgeoning LED industry, helping to test the spectral range, directionality and power of new lights with an impressive array of sensing instruments.
One, an “integrating sphere” two metres in diameter, gathers the light from devices hung within — electronically analyzing the intensity and colour quality of the beams collected on its white interior surface.
Venkataramanan predicts that all vacuum-based electronic illumination — from long fluorescent office lights to sodium-vapour street lamps — will be switched to “solid state” LED technologies in little more than a decade.
LEDs “are disruptively replacing almost every technology in lighting.”
LEDs lit to last
Current LED lights last an average of 20 times longer than incandescent bulbs.
They also convert about 10 times more electricity into light than the traditional Edison screw-ins — about 55 per cent compared to 5 per cent.
“Saving energy by having high efficiency … is as good as creating new energy,” says Cynthia Goh, director of U of T’s Institute for Optical Sciences.
Four bright ideas for LEDs
Blast them with blue
Sullen and sleepy, adolescents commonly trudge into morning classes ill prepared to take in their pre-lunch lessons. One solution proposed by some education researchers is to tune school LED lighting towards the cold, blue end of the spectrum. This would give the narcoleptic scholars a jolt of cortisol to boost their attention levels.
Patients need their rest after surgery. Established research has shown well-rested patients heal better and faster, improving outcomes and lowering health care costs. One idea that’s gaining ground in medicine is to place patients exiting the operating room in large-windowed rooms that can bathe them in natural sunlight. But this runs into cost and infrastructure problems in older hospitals. In the meantime, facilities are looking at LED lights tuned to natural solar spectrums to boost healing.
Jet lag lighting
Travellers taking long flights — especially eastward journeys — can often encounter days of lethargy as their circadian clocks align to new time zones. One way to help mitigate jet lag might be to tune LED lighting in airplane cabins to reflect the sunlight patterns passengers will experience on arrival. This could give them a head start in shifting their biological clocks to those on their adjusted watches and smart phones.
Nursery good night lights
The lights you turn off when putting your baby down for the evening may be the reason you’ll be up again in the middle of the night. The harsh blue light emitted by many existing fixtures can make it difficult for infants to sleep. Using LED lights that can be tuned to the warmer, reddish end of the spectrum might boost your baby’s melatonin levels, and ensure both infant and parents get a better night’s rest.
