US military’s ‘Jetson’ laser can ID your unique heartbeat from hundreds of feet away

Heartbeat rhythms are as unique as fingerprints, and lasers can identify their signature beats.

The U.S. military could soon spot you in a crowd — not by your face or your gait, but by your unique heartbeat rhythm. The Pentagon recently developed and tested a laser that can scan and distinguish the pitter-patter of your heart from up to 650 feet (200 meters) away.

Dubbed “Jetson,” the name recalls the popular sci-fi cartoon family the Jetsons, who inhabited a world full of futuristic gadgets. But unlike the handy household devices from the show, the new laser system was built for combatting terrorism, and was created by the Pentagon at the request of the U.S. Special Forces, MIT Technology Review (MTR) reported.

And unlike some types of identification techni...

Ingestible Origami Robot Removes Button Battery Stuck to Wall of Simulated Stomach

In experiments involving a simulation of the human esophagus and stomach, researchers at MIT, the University of Sheffield, and the Tokyo Institute of Technology have demonstrated a tiny origami robot that can unfold itself from a swallowed capsule and, steered by external magnetic fields, crawl across the stomach wall to remove a swallowed button battery or patch a wound.

The new work, which the researchers are presenting this week at the International Conference on Robotics and Automation, builds on a long sequence of papers on origami robots from the research group of Daniela Rus, the Andrew and Erna Viterbi Professor in MIT’s Department of Electrical Engineering and Computer Science.

“It’s really exciting to see our small origami robots doing something with potential ...

Defikopter drone air-drops a defibrillator to EMTs on the ground.Video & pics here.

The Defikopter is a UAV that can be activated by a smartphone app to automatically take to the skies and drop a defibrillator to medical personnel on the ground

We’ve seen flying drones designed to deliver food and even beer on command, but a new autonomous aircraft from a non-profit organization in Germany could provide medical equipment to remote areas in an emergency. The Defikopter is a UAV that can be activated by a smartphone app to automatically take to the skies and drop a defibrillator to medical personnel on the ground, shaving precious seconds from the time it takes to receive treatment for cardiac arrest.

The idea for the drone comes from Definetz, a non-profit group dedicated to preventing deaths due to heart failure...

If there’s anything we can take from the barrage of delivery drones to emerge recently, its that the technology has the potential to transport objects with unprecedented efficiency. Graduate student Alec Momont from Holland’s Delft University of Technology is looking to tap into this ability to reduce emergency response times to cardiac arrest incidents. His Ambulance Drone prototype carries a defibrillator to the scene and promises to dramatically increase the rate of survival.

Receiving treatment quickly can be the difference when it comes to heart attacks, with every passing minute lowering the chances of survival. Although public defibrillators are becoming more common, they aren’t everywhere and the public often doesn’t know how to use one or hesitates through lack of confidence...

A paralysed woman has been able to feed herself chocolate and move everyday items using a robotic arm directly controlled by thought, showing a level of agility and control approaching that of a human limb.

Jan Scheuermann, 53, from Pittsburgh, was diagnosed with a degenerative brain disorder 13 years ago and is paralysed from the neck down.

These electrodes are remarkable devices in that they are very small. You can’t buy them in Radio Shack.

“It’s so cool,” said Scheuermann during a news conference. “I’m moving things. I have not moved things for about 10 years … It’s not a matter of thinking which direction any more, it’s just a matter of thinking, ‘I want to do that’.”
