The fine folks at Mitsubishi Electric Research Labs (MERL) are demoing a new touchscreen system that may make small devices easier to use. An extension of their LucidTouch technology, NanoTouch has a small screen on the front and a touchpad on the back. Their test unit features a 2.4inch screen. The screen displays where the user’s finger is on the back touchpad as if the display was transparent. The user’s finger no longer obscures the screen surface, so it’s much easier to hit small buttons. In testing, researchers showed that targets just 1.8mm across were easy to hit. That’s much smaller than the iPhone’s touchscreen keyboard. Here’s a video demonstrating the new device.
We’re skeptical about most technology that’s designed to help remote villages (yes, even that one), but these new UAV medical couriers look like a great idea. The turn around time for medical sample analysis in remote South African villages can be excruciating. A team of engineers have attempted to adapt two different unmanned aerial vehicles for transport of medical samples. These could be either blood or saliva that needs testing. Test results would be relayed via phone as they are now, but the initial transport time would be much faster. The larger of the two UAVs can carry up to 500g; that’s enough to haul two units of blood for transfusion. The UAVs can be launched by hand and can survive winds up to 45kph. They fly their preprogrammed routes autonomously and don’t require any operator intervention. The team has flown two successful trials and is waiting for approval from the South African Civil Aviation Authority. For safety, they’re only transporting samples that can be sterilized before flight. New Scientist has a short video after the break. Continue reading “UAV medical couriers”
