The Department of Defense has released a smart phone mobile application to help service members use the therapeutic benefits of biofeedback.

BioZen, a mobile app from the Defense Department’s National Center for Telehealth and Technology, known as T2, uses wireless sensors to show the user their physical level of relaxation.

It is the first portable, low-cost method for clinicians and patients to use biofeedback in and out of the clinic.

“Mastering biofeedback successfully is difficult and frustrating for many people,” said Dr. David Cooper, T2 psychologist.

“This app takes many of the large medical sensors found in a clinic and puts them in the hands of anyone with a smart phone. BioZen makes it easier for anyone to get started with biofeedback.”

BioZen shows real-time data from multiple body sensors including electroencephalogram (EEG), electromyography (EMG), galvanic skin response (GSR), electrocardiogram (ECG or EKG), respiratory rate, and skin temperature. Each sensor sends a separate signal to the phone so users can see how their body is responding to their behavior.

TUBE FOOD

This is tube food.

And clearly, it’s exactly what it sounds like.

Meals encapsulated in things that look like toothpaste tubes. They come in all shapes and sizes, too. From entrees to desserts and even soups and meats, the assortment of tube food is varied and vast.

Pretty cool, eh?

Now, you might be asking yourself why tubes? Well, my first response to this would be why not? They’re convenient, they’re compact, and they just look cool. Meals in tube form, people. Come on!

I think I saw an old science fiction movie like this. They called it “the way of the future”. Might have been an MST3K.

Okay, okay, so coolness factor aside, there is an actual reason for these things to exist. And it all leads to U-2.

Honoring An Innovator

Naval Research Laboratory (NRL) Space Science Division (SSD) scientist Dr. George Carruthers has received the 2012 Medal of Technology National and Innovation. This is the nation’s highest honor for technology achievement, and it is bestowed by the president of the United States upon America’s leading innovators.

The award ceremony was held at the White House on February 1, 2013.

Dr. Carruthers grew up during the space race and was intrigued with space science.

While still a boy, he began building telescopes and model rockets and was an enthusiastic reader at the local libraries. His love for space science extended through his youth and eventually led him to pursue degrees in Aeronautical, Nuclear, and Astronomical Engineering from the University of Illinois.

Following his graduate studies, he accepted a position at NRL in 1964, after receiving a fellowship in Rocket Astronomy from the National Science Foundation. Throughout his tenure in the NRL SSD, Dr. Carruthers has focused his attention on far ultraviolet observations of the earth’s upper atmosphere and of astronomical phenomena.

In 1969 he received a patent for his pioneering instrumentation, “Image Converter for Detecting Electromagnetic Radiation Especially in Short Wave Lengths,” which detected electromagnetic radiation in short wave lengths.

Asteroid FlyBy On Friday

I spy with my little eye something…asteroid-y.

Okay, it’s an asteroid. And it’s HEADED RIGHT FOR US!

*ahem*

I apologize for the intentional panic-inducing ALL CAPS up there. But I mean really, how often does one get the chance to say that an asteroid is coming and have it actually be true? Because it’s coming!

Well it’s headed in our direction on Friday.

On Feb. 15th an asteroid about half the size of a football field will fly past Earth closer than many man-made satellites. Since regular sky surveys began in the 1990s, astronomers have never seen an object so big come so close to our planet.

Get your telescopes out, folks! This one’s going to set some records.

Saturday Space Sight: Water Bubble In Space!

Hey Instagramers, take a look at this one!

NASA astronaut Kevin Ford, Expedition 34 commander, watches a water bubble float freely between him and the camera, showing his image refracted, in the Unity node of the International Space Station.

This sure beats a picture of pancakes with an X-Pro II filter on them if you ask me.

Lab Testing Seeks Data on Modified Gunner Protection Design

The best way to evaluate the effectiveness of a product is to put it in the hands of the user, obtain feedback, and make adjustments accordingly.

With a newly developed Virtual Environment Test Bed, or VETB, scientists and engineers at the Target Behavioral Research Laboratory at Picatinny Arsenal can record how soldiers react and perform inside a newly modified Objective Gunner Protection Kit, or OGPK.

The OGPK is an armored turret that provides much-needed protection for tactical vehicle gunners in combat situations. Soldiers voted the OGPK as one of the Army‘s top 10 Greatest Inventions in 2007, the year it was first fielded.

“The purpose of testing the OGPK in a virtual test bed is to evaluate gunner performance in various threat scenarios,” said Thomas Kiel, chief, Turret Engineering and Force Protection in the Systems Engineering Directorate, part of the U.S. Army Armament Research, Development and Engineering Center, known as ARDEC.

A customized version of the “America’s Army” gaming environment was integrated with the actual OGPK hardware and weapon system to provide a more realistic simulation.

U.S. Naval Research Laboratory scientists in the Electronics Technology and Science Division, in collaboration with the Imperial College London and MicroLink Devices, Inc., Niles, Ill., have proposed a novel triple-junction solar cell with the potential to break the 50 percent conversion efficiency barrier, which is the current goal in multi-junction photovoltaic development.

“This research has produced a novel, realistically achievable, lattice-matched, multi-junction solar cell design with the potential to break the 50 percent power conversion efficiency mark under concentrated illumination,” said Robert Walters, Ph.D., NRL research physicist.

“At present, the world record triple-junction solar cell efficiency is 44 percent under concentration and it is generally accepted that a major technology breakthrough will be required for the efficiency of these cells to increase much further.”

In multi-junction (MJ) solar cells, each junction is ‘tuned’ to different wavelength bands in the solar spectrum to increase efficiency. High bandgap semiconductor material is used to absorb the short wavelength radiation with longer wavelength parts transmitted to subsequent semiconductors.

In theory, an infinite-junction cell could obtain a maximum power conversion percentage of nearly 87 percent. The challenge is to develop a semiconductor material system that can attain a wide range of bandgaps and be grown with high crystalline quality.

Today’s soldiers are strong and technologically savvy, and the Army aims to continue to attract these young people to its ranks, said Deputy Assistant Secretary of the Army for Marketing Mark S. Davis.

The Army also wants to educate the public about the many opportunities it offers young people who want careers in science and technology, said Davis, who also is the director of Army Marketing and Research Group, or AM&RG, which was created in April 2011.

“The more we expose the public to our soldiers, civilians and family members, the stronger our brand becomes, the more our story is understood and believed, and the more comfortable influencers and potential prospects are in recommending or serving in our ranks.”

One AM&RG initiative, started a year ago, involves science, technology, engineering and mathematics, or STEM, activities and competitions in high schools across the country.
