The SODIS method is ideal for treating water for drinking in developing countries. All it requires is sunlight and PET bottles. How does it work? Clear PET bottles are filled with the water and set out in the sun for 6 hours. The UV-A rays in sunlight kill germs such as viruses, bacteria and parasites (giardia and cryptosporidia). The method also works when air and water temperatures are low.
People can use the SODIS method to treat their drinking water themselves. The method is very simple and its application is safe. It is particularly suitable for treating relatively small quantities of drinking water.
Launching with acclaim on Kickstarter, the 3Doodler literally puts the power of 3D printing in your hands. Consisting of an oversized pen device, it houses an extruder similar to that used in low-end 3D printers. At the press of a button, PLA or ABS filament emerges to be dynamically controlled into whatever shape you desire.
The ReWalk™ exoskeleton suit uses patented technology with motorized legs that power knee and hip movement. Battery-powered for all-day use, ReWalk is controlled by on-board computers and motion sensors, restoring self-initiated walking without needing tethers or switches to begin stepping. ReWalk controls movement using subtle changes in center of gravity, mimics natural gait and provides functional walking speed. A forward tilt of the upper body is sensed by the system, which triggers the first step.
Therapeutic play helps promote cognitive, social, and physical skill development in children. Recent articles report how tablet computers are used to provide an inexpensive therapeutic device to engage children with visual, cognitive, and learning disabilities through various therapy and rehabilitation apps. Although this current market is growing, what has been overlooked is the large populace of children with limited fine motor skills, such as those with neurological movement disorders that include cerebral palsy, traumatic brain injury, spina bifida, and muscular dystrophy. These children are kept from interacting with touch-based tablet computers due to difficulties in 'touching' a specific small region with appropriate intensity and timing (i.e. effecting press and swipe gestures).
