Innovative system for the rehabilitation of people with brain damage
The Biomechanics Institute of Valencia (IBV) is currently taking part in the European project WALKX with the aim of developing an innovative rehabilitation system to improve the quality of life of people who have suffered brain damage. This system will allow home rehabilitation and improve patient’s autonomy.
WALKX is a two-year research project for the benefit of small and medium sized enterprises (SMEs), co-funded by the European Commission through the Seventh Framework Programme.
The user friendly walking training device the partners are designing will support the patient in raising from sitting to standing position and enable the patient to perform walking training and improve his/her manoeuvrability. “An upper body stabilizing and controllable supporting vest will be developed. Early in the rehabilitation process it will be used under supervision of a therapist, but with greatly reduced need for physical support from the therapists. This is intended to reduce the need for help from others and increase freedom of movement and personal autonomy of the patient”, said Ignacio Bermejo, Market Innovation Director at IBV.
One of the novelties of this device consists of a vest with attachment points on the patient’s waist in order to regulate the mobility of the trunk. Also, the device will be modular and low cost. The role of IBV in this initiative has been to define the design specifications and preclinical testing to validate the prototype. Preclinical tests are done in collaboration with the Department of Physical Medicine and Rehabilitation at the Hospital Universitari i Politècnic La Fe of Valencia.
The project is coordinated by the Norwegian company Made for Movement Group. Besides Biomechanics Institute, other members of the consortium are Innovatsiooni Eesti Instituut (Estonia), INNORA ROBOTICS (Greece), Newtrim and MCT (UK), ENIX (France), Motus (Italy) and MOBILE ROBOTICS SWEDEN (Sweden).
Stroke (cerebrovascular accident) is the most common cause of adult disability in Europe. Roughly 75% of victims survive, but about half of these lose the ability to live independently in their own home. As strokes often result in long term disability rather than death, the rehabilitation and hospitalisation represent a major economic burden for the EU of about €34 Bn annually. Currently, the annual incidence is approximately 2 per 1,000 inhabitants in the EU, and the number is predicted to double over the next 50 years due to the aging of the population.
GE Silent Scan turns down the volume on MRI scanners
GE Healthcare has introduced a new data acquisition technology designed to improve patient comfort by largely eliminating the horrible noise generated during an MRI scan. Conventional MRI scanners can generate noise levels in excess of 110 dBA (creating a din that sounds like a cross between a vehicle’s reverse warning horn and a Star Trek phaser) but GE says its new Silent Scan MRI technology can reduce this to just above background noise levels in the exam room.
The noise that MRI scanners produce is related to changes in the magnetic field that allow the slice by slice body scan to be carried out. In recent years, industry efforts to speed up the scanning process have also resulted in louder and louder scans. The designers have attempted to dampen these noises with mufflers and baffles, achieving only limited success.
Silent Scan is achieved through two new developments. First, acoustic noise is essentially eliminated by using a new 3D scanning and reconstruction technique called Silenz. When the Silenz protocol is used in combination with GE’s new high-fidelity MRI gradient and RF system electronics, the MRI scanning noise is largely eliminated at its source.
At the 2012 meeting of the Radiological Society of North America, an MRI system compatible with the Silent Scan technology was linked into a soundproof room. When the MRI system used conventional scanning methods, a staccato, stuttering racket with noise peaks up to 110 dBA was heard. However, when Silent Scan was switched on, the noise level dropped to 76 dBA, just above the background noise of the MRI electronics. This is accomplished without substantial trade-offs in scanning time or image quality, according to Richard Hausmann, president and CEO, GE Healthcare MR. The comparison is shown in this video.
Silent Scan technology has not yet obtained 510k Premarketing Notification clearance from the FDA, so it’s not yet available for sale. GE is presumably hoping for a decision that Silent Scan is “substantially equivalent” to existing MRI scanners, a result that would greatly simplify the new technology’s entry into the diagnostic market.
Humanity’s merge with its technology, which began shortly after the taming of fire, is still happening today. Many predict that the fine-tuning of our DNA-based biology through stem cell and genetic research will spark a powerful nanotech revolution that promises to redesign and rebuild our bodies and the environment, pushing the limits of today’s understanding of life and the world we live in.
Nanotech will change our physical world much the same way that computers have transformed our information world. Physical things such as cars and houses could follow the same path of computers, when Moore’s Law correctly predicted value-to-cost would increase by 50% every 18 months.
Existing products that are now expensive, such as photovoltaic solar cells, will become so cheap in the decades ahead, that it may one day be possible to surface roads with solar-collecting materials that would also gather energy to power cars, ending much of the world’s dependency on fossil fuels.
In addition, imagine machines that create clothing, medicine, food and most essentials, with only your voice needed to command the action. Today, such devices are not available, but by early 2030s, experts predict, a home nanofactory will provide most of your family’s needs at little or no cost.
Now bring on the most amazing impending revolution – human-level robots – with intelligence derived from us, but with redesigned bodies that exceed human capabilities. These powerful android creatures expected by 2030, will enable us to tap into their super-computer minds to increase our own intelligence. Constructed with molecular nanotech processes, they will be affordable for every family.
Finally, by mid-century, many people will complete the technology merge by replacing more of their biology with nanomaterials, creating a powerful body that can automatically repair itself when damaged. No more concerns over sickness, accidents, or unwanted death.
Evolution created humanity; humanity created technology, humanity will soon become technology. This is simply our next evolutionary step. Where this trip will take us may be beyond present day knowledge, but whatever the future holds, many people alive today can expect to experience all of its wonders.
Of course, not everyone may hold such a glowing vision of how life may unfold, but for one who has seen so many amazing changes over the past eighty two years, I think it difficult to imagine a negative outcome as we trek through what promises to be an incredible future.
Device Helps Children with Disabilities Access Tablets
Imagine not being able to touch a touch-screen device. Tablets and smartphones—with all their educational, entertaining and social benefits—would be useless.
Researchers at Georgia Tech are trying to open the world of tablets to children whose limited mobility makes it difficult for them to perform the common pinch and swipe gestures required to control the devices.
Ayanna Howard, professor of electrical and computer engineering, and graduate student Hae Won Park have created Access4Kids, a wireless input device that uses a sensor system to translate physical movements into fine-motor gestures to control a tablet.
The device, coupled with supporting open-source apps and software developed at Georgia Tech, allows children with fine motor impairments to access off-the-shelf apps such as Facebook and YouTube, as well as custom-made apps for therapy and science education.
“Every child wants access to tablet technology. So to say, ‘No you can’t use it because you have a physical limitation’ is totally unfair,” Howard said. “We’re giving them the ability to use what’s in their mind so they have an outlet to impact the world.”
The current prototype of the Access4Kids device includes three force-sensitive resistors that measure pressure and convert it into a signal that instructs the tablet. A child can wear the device around the forearm or place it on the arm of a wheelchair and hit the sensors or swipe across the sensors with his or her fist. The combination of sensor hits or swipes gets converted to different “touch-based” commands on the tablet.
Children with neurological disorders such as cerebral palsy, traumatic brain injury, spina bifida and muscular dystrophy typically suffer from fine motor impairments, which is the difficulty of controlling small coordinated movements of the hands, wrists and fingers. They tend to lack the ability to touch a specific small region with appropriate intensity and timing needed for press and swipe gestures.
IBM: Computers Will See, Hear, Taste, Smell and Touch in 5 Years
Today’s PCs and smartphones can do a lot — from telling you the weather in Zimbabwe in milliseconds, to buying your morning coffee. But ask them to show you what a piece of fabric feels like, or to detect the odor of a great-smelling soup, and they’re lost.
That will change in the next five years, says IBM. Computers at that time will be much more aware of the world around them, and be able to understand it. The company’s annual “5 in 5” list, in which IBM predicts the five trends in computing that will arrive in five years’ time, reads exactly like a list of the five human senses — predicting computers with sight, hearing, taste, smell and touch.
The five senses are really all part of one grand concept: cognitive computing, which involves machines experiencing the world more like a human would. For example, a cognizant computer wouldn’t see a painting as merely a set of data points describing color, pigment and brush stroke; rather, it would truly see the object holistically as a painting, and be able to know what that means.
Those just as concerned about where they’ve been as where they’re going might be keen to give the “FlyViz” a go. Created by a team of French researchers to expand the scope of human vision, the prototype system captures vision on a 360-degree camera attached to the top of a helmet that is processed in real time and displayed on Sony’s HMZ-TD Personal 3D Viewer, giving the wearer a 360-view of their surroundings.
Academics at Cambridge University are pondering the risk to humanity from super-intelligent technology which could “threaten our own existence.”
Huw Price, Bertrand Russell Professor of Philosophy at Cambridge, said: “In the case of artificial intelligence, it seems a reasonable prediction that some time in this or the next century intelligence will escape from the constraints of biology.”
Professor Price is planning to launch a research centre next year looking into the danger, teaming up with Cambridge professor of cosmology and astrophysics Martin Rees and Jann Tallinn, one of the founders of Skype.
He wants to bring more attention to a future in which mankind might be at the mercy of “machines that are not malicious, but machines whose interests don’t include us.”
The group won’t be the first people to ponder such a future, which has featured in science fiction since the dawn of the computer age, perhaps most famously with HAL- the malevolent computer from Stanley Kubrick’s 2001: A Space Oddyssey- and most recently in I, Robot, starring Will Smith.
Acknowledging that many people believe his concerns are far-fetched, Professor Price said: “It tends to be regarded as a flaky concern, but given that we don’t know how serious the risks are, that we don’t know the time scale, dismissing the concerns is dangerous.”
He said that advanced technology could be a threat when computers start to direct resources towards their own goals, at the expense of human concerns like environmental sustainability.
He compared the risk to the way humans have threatened the survival of other animals by spreading across the planet and using up natural resources that other animals depend upon.
… and does Google and Wikipedia make it better or worse? Studies show that other people and tools influence our brain power as much as our own minds.
…
Research shows that people don’t tend to rely on their memories for things they can easily access. Things like the world in front of our eyes, for example, can be changed quite radically without people noticing. Experiments have shown that buildings can somehow disappear from pictures we’re looking at, or the people we’re talking to can be switched with someone else, and often we won’t notice – a phenomenon called “change blindness”. This isn’t as an example of human stupidity – far from it, in fact – this is an example of mental efficiency. The mind relies on the world as a better record than memory, and usually that’s a good assumption.
As a result, philosophers have suggested that the mind is designed to spread itself out over the environment. So much so that, they suggest, the thinking is really happening in the environment as much as it is happening in our brains. The philosopher Andy Clark called humans “natural born cyborgs”, beings with minds that naturally incorporate new tools, ideas and abilities. From Clark’s perspective, the route to a solution is not the issue – having the right tools really does mean you know the answers, just as much as already knowing the answer.
Smart specs may replace guide dogs
Smart specs for the blind that could take the place of white canes and guide dogs may be available in two years, researchers have said.
The hi-tech glasses are designed to prevent “legally blind” individuals with a small degree of residual vision from bumping into objects.
They use tiny stereo cameras in the frames to project simplified images onto the lenses which become brighter the closer an object is.
From January next year the glasses will be tested in a series of trials involving 160 people with severely impaired sight in Oxford and London. Developer Dr Stephen Hicks, from Oxford University, said he hoped a finished model will be commercially available in around two years.
The cost is expected to be around £600 - slightly more than a smart phone. In comparison, a guide dog costs up to £30,000 to train.
Dr Hicks said the spectacles were designed as a navigational aid, not to restore lost vision.
"The glasses work using a pair of cameras that determine the distance of objects and we simply translate that into a light display," he said. "This is not restoring sight, but we can improve spatial awareness."
Around 300,000 people in the UK are registered as legally blind. Of these, 90% possess some residual vision allowing them to detect blurry shapes and differences between light and dark.
"The aim is to increase the independence of the hundreds of thousands of people who are visually impaired in the UK," said Dr Hicks.
The research was funded through the National Institute for Health Research Invention for Innovation (i4i) programme.
