Invisible Bike Helmet

“Though it’s nearing the end of summer, bicyclists will still be hitting the roads for the next couple of months. Hopefully most of them will be wearing helmets, though you will invariably see a few who are not because of the undesirable fashion statement and/or inconvenience of post-ride “helmet hair” (though having seen some of the injuries associated with not wearing helmets, this author believes that people who subscribe to the latter reason have not encountered true inconvenience.) These people may be in luck, however, thanks to the work of Hövding, a design/engineering/generally awesome company based in Sweden.

The invisible bike helmet is essentially a (visible) collar that bicyclists wear around their necks, the idea being that it will appeal to both users’ fashion sense and ergonomic need for insulation. Upon sensing an impact, the collar uses a small helium gas inflator to blow up a hood-shaped nylon airbag around the user’s head in about 100 milliseconds – cushioning the cranium before impact. The collar also contains a black box that records 10 seconds of movement data (from embedded accelerometers and gyros) during, and immediately before, a cycling accident. For more information, check out the video below.


This appears to be an exciting development for bicyclists who don’t have many options when it comes to fashionable head protection. We previously covered a nascent solution for motorcyclists that embedded a fast cooling mechanism in the helmet and are glad to see that an increasing number of companies are working on cool, potentially life-saving technologies like these.”


Caring for your heart (while you sleep)



After reading this I can’t sleep on my left side anymore. I feel uncomfortable and it bothers me, because even though I know it might not make a huge difference, I know that I do have a choice if I want it to make any difference at all!
Caring for your heart

GPS Shoes for Tracking Down Alzheimer’s Patients


gvq9re8ifdj GPS Shoes for Tracking Down Alzheimers Patients  by STANLEY DARMA on Oct 26, 2011 • 12:09 pm

Shoes with built-in GPS could be useful for two purpose: either tracking down your lost shoes or tracking down the person who is wearing them. GTX Corp figured the latter option might be useful for safety purposes, especially for people who suffer from Alzheimer’s disease or other forms of dementia. The company has been developing these shoes for two years now, which will feature a built-in GPS in the heels.

The purpose of the GPS is to ensure that family or other caregivers can see where the monitored person is at any given time. A primary feature of the service is an alarm system which will alert the family or caregivers when the person who is wearing the shoes is moving beyond a certain area. In the past there have been other GPS devices, like bracelets or watches, but these can easily get lost or the user forgets  to wear them. Shoes, however, are items that are difficult to forget when venturing outside the home.

GTX corp originally designed the shoes for children and long-distance runners, but professor Andrew Carle of George Mason University’s College of Health and Human Services advised to target the shoes at the elderly. The company expects that people will see the benefits of the shoes, such as less exposure to dangerous situations. And by preventing people getting lost, less money will be spent on finding people. The GPS shoes will sell for $300 a pair and are scheduled to go on sale this month in the US.

Mechanical Fingers Give Strength, Speed to Amputees


“Invented by Dan Didrick of Naples, Florida, the device has no batteries, electronics, servos or actuators. Instead, each digit incorporates a simple mechanism which, when pushed by the surviving part of the wearer’s finger, curls a set of artificial phalanges.”

“Made of steel and blue plastic, Didrick’s X-Finger allows for a surprising degree of dexterity: Enough to grip (and swing) a golf club, operate a keyboard or even play musical instruments.”
