A new technique verifies and identifies a person based on features drawn from electrocardiographic (ECG) leads. It can identify a person from a group of known subjects, or verify a person to allow access to a secure facility or access to Internet control of computers, airplanes, weapons, and alarms. It uses the ECG signals generated by the heart during contraction and relaxation that are characteristic to an individual. The method can be used by homeland security personnel and law enforcement, and in airports and other high-security locations. Find out more HERE.

Meanwhile on the Space Station…

NASA astronaut Scott Kelly and Russian Cosmonaut Mikhail Kornienko have begun a one-year mission in space. The mission will help researchers better understand how the human body reacts and adapts to long-duration spaceflight. While on the ISS, Kelly’s identical twin brother, retired NASA astronaut Mark Kelly, will undergo comparative genetic studies. Differences, or lack thereof, between the Kelly brothers after Scott’s year in space and Mark’s year on Earth could shed new light on the effects of spaceflight on the human body.

Editor's Choice: May 2015 - NASA Tech Briefs

A MEMS micro-translation stage features large linear travel capability, and can translate across long distances using just three-phase power. Essentially a linear motor built from a silicon base using microfabrication techniques, the device can be as small as 100 mm and can house lenses, mirrors, absorbers, and sampling compartments for applications in optics, communications, sensors, and biotechnology.

Freezing for Survival

The James Webb Space Telescope (JWST) will have to survive the mechanically stressing conditions of launch, and the telescope and scientific instruments will have to survive the thermal shrinkage that occurs when cooling down from room temperature to the cryogenic temperatures at which they operate. This is a significant engineering challenge because the JWST and its instruments operate at extremely cold temperatures, but they are built at room temperature.
