Calling All Inventors! NASA Wants Your Ideas For Mindshift

 

Inventors, get your minds in gear to apply NASA’s Mindshift technology to your next invention.  NASA (the National Aeronautics and Space Administration) has partnered with Edison Nation to identify the best consumer inventions or product adaptations to use with its powerful mind control tool, Mindshift.

For those of you who are not familiar with the technology, Mindshift is a physiological feedback system, developed by NASA’s Langley Research Center, that monitors and provides feedback about a person’s heart rate, muscle tension, and brainwave activity – all stress indicators.  The feedback system allows you to control these stress indicators so that you can perform optimally.

Today, NASA’s Mindshift technology is being used alongside motion-sensing gaming technology like the Wii and Xbox.  As the Mindshift controls are independent of the gaming program and control, Mindshift provides biofeedback to the user without interfering with the game, thus allowing the gamer to modify his stress levels so he or she can play better. Mindshift is also being explored for use in educational, psychological, and medial situations.

Now, NASA is looking for new and adapted consumer products to use with Mindshift.  What activities of home or work life would benefit from the ‘mind control’ that the Mindshift technology offers?  What application can you create or modify to enhance this activity?

NASA project could be next big thing in video games

The video game’s description promised that two doctors were about to be swallowed by the jaws of fate.

Watching the action on the screen, Alan Pope said, somewhat unnecessarily, “You want to be careful with the scalpel when it’s jumping around.”

“This is really tricky,” replied Chad Stephens, studying the chest he was about to cut open.

The NASA research scientist wore a headset with sensors that monitored his brain waves. As he focused, his brain waves changed frequency, indicated by changing colors of LED lights below the screen. They flickered between red and yellow, then steadied on green. Stephens made a sudden movement with his hand.

“Oh, that’s good!” Pope exclaimed. A robotic voice from the game “Trauma Center: New Blood” intoned, “The incision has been made.”

Pope has a master’s degree in electrical engineering and a doctorate in clinical psychology. Stephens is working on his psychology dissertation. Both work in aeronautics at NASA’s Langley Research Center, where their core research on cockpit design has led to an interesting spinoff: a biofeedback device that makes video games harder for tense or distracted players.

The application is the latest in Pope’s research on brain wave monitoring. His studies on cockpit automation in the 1990s led to the creation of attention-training games by a North
Carolina company.

It’s all part of NASA’s transfer of tax-funded research into the private sector for development of new products and uses that benefit the public as well as the space agency. Langley research has been used by Speedo to create faster racing swimsuits, by Medtronics Inc. to stabilize heart-failure patients, and by NASCAR to clean air inside race cars.

NASA research can be found in medical devices, industrial smokestack scrubbers, panoramic cameras, solar refrigerators, emergency air supplies for coal miners, parachutes for airplanes and more. The agency says its research has been used to save 444,000 lives since 2004, and has generated $5.1 billion for the economy.

The biofeedback technology is commercially available from NASA’s Technology Gateway. Its inventors say it could be used in anything from video games to training simulations for medical doctors to athletes – wherever improved concentration would also improve performance.

“We didn’t invent the Wii, and we didn’t create the game,” Stephens said, “but we figured out how we could modify the controls to serve as feedback to the user.”

In April, NASA obtained a patent for using the technology, called MindShift, on the Wii gaming system. An application has been submitted for Kinect.

“If a company was interested, it could involve this biofeedback mechanism into a game,” Stephens said. “For example, a wizard could use his mental powers to go through the game. Maybe use it in a challenge here and there to demonstrate his skill.

“We could measure fear and have that impact the game in some way. It has the potential to involve a player’s real emotion into the game.”

NASA uses the technology to assess new cockpit designs by monitoring brain waves, heart rate and eye movement of pilots in a simulator.

“We want to be able to sense what kind of state they’re in and provide feedback on a continuous basis so they can understand how their state affects their performance,” Pope said. “If we design something that takes up too much of their attention or doesn’t draw their attention, we probably have poor design.”

Pilots can be taught to focus through standard biofeedback training, where the subject tries to control his heart rate, for example, while moving a line or a bar on a monitor. That can be boring, Pope said. Many of the test pilots enjoyed golf, so the researchers incorporated the biofeedback training into a game where being “in the zone” – mind in perfect sync with body – is important.

They tested a putting green that reacted to a player’s brain waves. When stressed or unfocused, the biofeedback mechanism caused the indoor putting green to undulate, the hole to shrink and a targeting laser to swing back and forth. By relaxing and focusing on the task at hand, players could sink the putt more easily.

Then the researchers tried it with video games, which have real-world possibilities, too.

“Playing a surgery game with an unsteady hand is challenging,” Pope said. “You could imagine this as a surgeon in training learning how to focus, while it teaches the manual skill of surgery.”

They booted up “Link’s Crossbow Training” on the Wii. Pope put on the headset, with a clip on his left earlobe to track his pulse. The cursor jumped around, and he couldn’t aim until his heart rate slowed.

He picked off a single target on the first screen and two targets on the next. Then five targets popped up at once, and the cursor jumped around so he couldn’t aim.

“Got a little excited there,” Pope said. As he calmed down and focused, the cursor steadied and he knocked down the targets one after the other.

“We think this is the next stage beyond motion sensing games,” he said. “That’s why we call it MindShift. We wanted developers to think about games in different ways. That would require a mind shift.”

Ultraviolet-Blocking Lenses Protect, Enhance Vision

In the 1980s, Jet Propulsion Laboratory (JPL) scientists James Stephens and Charles Miller were studying the harmful properties of light in space, as well as that of artificial radiation produced during laser and welding work. The intense light emitted during welding can harm unprotected eyes, leading to a condition called arc eye, in which ultraviolet light causes inflammation of the cornea and long-term retinal damage.

alt

Based on work done at NASA’s Jet Propulsion Laboratory, Eagle Eyes lenses filter out harmful radiation, reduce light scattering, and permit vision-enhancing wavelengths of light, protecting eyesight while also improving visibility.

To combat this danger, the JPL scientists developed a welding curtain capable of absorbing, filtering, and scattering the dangerous light. The curtain employed a light-filtering/vision-enhancing system based on dyes and tiny particles of zinc oxide—unique methods they discovered by studying birds of prey. The birds require near-perfect vision for hunting and survival, often needing to spot prey from great distances. The birds’ eyes produce tiny droplets of oil that filter out harmful radiation and permit only certain visible wavelengths of light through, protecting the eye while enhancing eyesight. The researchers replicated this oil droplet process in creating the protective welding curtain.

 

The welding curtain was commercialized, and then the scientists focused attention on another area where blocking ultraviolet light would be beneficial to the eyes: sunglasses. In 2010, the groundbreaking eyewear technology was inducted into the Space Foundation’s Space Technology Hall of Fame, which honors a select few products each year that have stemmed from space research and improved our lives here on Earth.

Partnership

SunTiger Inc.—now Eagle Eyes Optics, of Calabasas, California—was formed to market a full line of sunglasses based on the licensed NASA technology that promises 100-percent elimination of harmful wavelengths and enhanced visual clarity. Today, Eagle Eyes sunglasses are worn by millions of people around the world who enjoy the protective and vision-enhancing benefits.

Product Outcome

The Eagle Eyes lens (right) makes scenes more vivid because harmless wavelength colors such as red, orange, yellow, and green are enhanced, and damaging rays in the blue, violet, and ultraviolet (UV) wavelengths are blocked.

Maximum eye protection from the Sun’s harmful ultraviolet rays is critical to our ability to see clearly. This is because when light enters the eye, a series of events happen which can help, hinder, or even destroy our eyesight. First, light passes through the cornea and ultimately reaches the retina which contains two types of cells—rods (which handle vision in low light) and cones (which handle color vision and detail). The retina contains 100 million rods and 7 million cones. The outer segment of a rod or a cone contains the photosensitive chemical, rhodopsin, also called “visual purple.” Rhodopsin is the chemical that allows night vision, and is extremely sensitive to light. When exposed to a full spectrum of light, rhodopsin immediately bleaches out, and takes about 30 minutes to fully regenerate, with most of the adaption occurring in the dark within 5 to 10 minutes. Rhodopsin is less sensitive to the longer red wavelengths of light and therefore depleted more slowly (which is why many people use red light to help preserve night vision). When our eyes are exposed to the harmful, ultraviolet light rays of the Sun (UVA, UVB, and blue-light rays), damage to our eyes and their complex vision-enhancing processes can occur and not even be noticed until years later, long after exposure.

The most common form of eye damage related to ultraviolet exposure, cataracts, causes the lens of the eye to cloud, losing transparency and leading to reduced vision and, if left untreated, blindness. In the United States alone, it is estimated that cataracts diminish the eyesight of millions of people at an expense of billions of dollars. Other forms of eye damage directly attributable to ultraviolet exposure include pterygium, an abnormal mass of tissue arising from the conjunctiva of the inner corner of the eye; skin cancer around the eyes; and macular degeneration, which damages the center of the eye and prevents people from seeing fine details.

Alan Mittleman, president and CEO of Eagle Eyes explains, “When we’re born, our eyes are clear like drops of water. Throughout life, we start to destroy those sensitive tissues, causing the yellowing of the eyes and the gradual worsening of eyesight. When the eye becomes more and more murky, cataracts form. Simple protection of the human eye, from childhood and throughout adulthood could protect the clarity of the eye and extend good vision for many years—even our entire lifetime.

“It has only been recently,” he adds, “that people started to realize the importance of this.” Sunglass manufacturers are recognizing the importance of eye care, and consumers are becoming more aware of eye health. One issue still plaguing the sunglass market, though, is that consumers assume that darker lenses are more protective, which is not always the case.

 

It may feel more comfortable to wear the dark lenses, but in addition to reducing the field of vision, it relaxes the eye, which allows more blue light to get directly to the retina. Blue light, in particular, has long-term implications, because it passes through the cornea and damages the inner retinal area.

The Eagle Eyes lens allows wearers to see more clearly because it protects from ultraviolet light, but more importantly, blocks this blue light, allowing the good visible light while blocking the harmful wavelengths.

Among their many donations throughout the years and goal of spreading good vision and eye protection to remote areas of the world, Eagle Eyes Optics had the opportunity recently to provide assistance to a group in sore need of eye protection: children in Galena, Alaska. The incidence of cataracts is 300 times greater in Alaska because of the Sun’s reflection off of the snow. Eagle Eyes donated 150 pairs of its sunglasses to a high school in Galena, and they were delivered by members of the Space Foundation and presented by former NASA astronaut Livingston Holder.

Why Should We Spend Money on the NASA Space Program?

NASA budget grapghThe point to spending on the space program, for example, is shown by the timeline of spinoff technologies [1]. I’m preparing the fiscal numbers using the information posted on this blog to look into asking, “What is the financial effect of science and technology funding?”, so the Apollo program is a perfect example for looking into this question. As discussed in the timeline, Apollo led to “cool suits alleviate dangers from high-heat environments and medical conditions, Kidney dialysis machines remove toxic waste from used dialysis fluid, A machine aids physical therapy and athletic development, A stress-free ‘blow molding’ process manufactures athletic shoes, Communities benefit from water purification technology, Manufacturers preserve food through freeze-drying, and Sensors detect hazardous gasses.”

In today’s money, the $20.4 billion spent on the Apollo program is equivalent to $109 billion [2]. If we look at the markets that exist now because of these technologies (attempt to estimate the revenue gained if the technology did not now exist), then the dialysis market brings in $16 billion A YEAR (+, more than that due to secondary effects from increased quality of life) [3], the sports coaching market (which would benefit from a “machine aids athletic development”) brings in $6 billion a year (-, less because an athletic development machine would only lead to changes in part of the market) [4], the physical therapy market brings in $30 billion a year (-, less is attributable to the technology) [5], the athletic shoe market brings in $75 billion a year (-, less) [6], the water purification market brings in $20 billion a year (+, more from secondary effects) [7], and the hazardous gas detection market is $2 billion a year (+, more) [8]. Note that I have not been able to assemble fiscal numbers on all of the technologies listed above because of time constraints to do all the research. Also, the spinoff timeline did not mention that the Apollo program led to the development of the expendable launch vehicle market which is $53 billion over the next 10 years [9].

So finally, we can get our hands on a comparison. $20.4 billion spent in 1970 on the space program translates to somewhere around $154.3 billion dollars _A YEAR_ in technology-based markets. What this roughly indicates is that the cuts in NASA funding is the farming equivalent to eating your seed corn.

NASA Installs LITO Technologies’ Innovative Perimeter Monitoring System

 LITO Technologies Perimeter Security System / LITO Technologies' Perimeter Security System, installed at NASA Glenn Research Center (PRNewsFoto/LITO Technologies, Inc.)A collaboration of LITO Technologies, Inc. and NASA’s Glenn Research Center,Cleveland, Ohio, has resulted in the launch of new technology which will revolutionize security monitoring systems.  Furthermore, this type of collaboration could prove to be a new model to help publicly funded technology make the transition to privately funded commercialization.

The product of NASA’s SBIR Grants, the LITO (Laser Imaging Through Obscurants) system, from LITO Technologies, Inc., allows monitoring and sensing in visually obscured weather conditions such as rain, snow, fog, hail and smoke, sand, and dust. It was designed initially to be an onboard sensor for aircraft landing, but the uses for perimeter screening in top security usage became immediately evident.

LITO allows for continual monitoring of a location or multiple locations regardless of how bad weather scenarios may get.

Last month, the LITO Omnivid-1 security system was installed at NASA Glenn for perimeter protection and will also provide a demonstration for other government agencies that may have similar perimeter security requirements.

Because the LITO system can also see through obscurants such as sand, dust, and even fire, the LITO technology will soon cover many sectors including aircraft imaging, border security, firefighting, search and rescue, and potentially even asteroid mapping.

The entire project is an example of the public and private sectors partnering with the input of advanced-thinking entrepreneurs and scientists like LITO’s Robert ForakerJared Sullivan, and Dr. Richard Billmers who are working in cooperation with NASA technology projects to create and commercialize advanced technical solutions effectively.

Dr. Richard Billmers, also of RL Associates of Yardley, Pennsylvania, had developed elements of the LITO systems for onboard aircraft sensors, under NASA SBIR Aviation Grants in conjunction with NASA Langley Research Center, Hampton Virginia. Successful demonstrations on the ground and in-flight have resulted in a commercialization strategy that begins with perimeter security applications.  The commercialization path will lead to smaller more compact LITO systems that will eventually be used in aircraft to visualize runway scenarios in inclement weather as a part of the Next Generation of Air Flight program.

Billmers was invited by NASA to present his LITO system at their 2012 Technology Days event in Cleveland Ohio. The event was to showcase technology and companies in an effort to stimulated new start ups, and economic growth for the area. The effort seems to have worked.

Robert Foraker, a Private Merchant Banker from Canton, Ohio, and 10 year recipient of NASA agreements, was impressed with the LITO system, when he saw it at the Technology Days event, and authored a collaboration agreement with RL Associates to bring the LITO system to ground based use at NASA Glenn. Foraker fielded the private funding required for the project from a progressive management company called The Woodhaven Group, out of Augusta, Georgia, managed by Jared Sullivan, with whom Foraker had previously worked through his ACT International Incubator.

The entire LITO/NASA collaboration process began and came together in just 51 weeks from the Technology Days event, in 2012, culminating in a Space Act Agreement between NASA’s Glenn Research Center, and LITO in 2013.

This collaboration was made in an effort to get advanced technology commercialized for public use, and help streamline the way the public sector and private sector work together to move technology forward as a whole. Hopefully, this will be just the first of many collaborations between NASA and the private sector to help technological entrepreneurs, by showcasing the technology and moving it to market quickly.

Behavior Prediction Tools Strengthen Nanoelectronics

NASA Technology

Several years ago, NASA started making plans to send robots to explore the deep, dark craters on the Moon. As part of these plans, NASA needed modeling tools to help engineer unique electronics to withstand extremely cold temperatures.

According to Jonathan Pellish, a flight systems test engineer at Goddard Space Flight Center, “An instrument sitting in a shadowed crater on one of the Moon’s poles would hover around 43 K”—that is, 43 kelvin, equivalent to -382 °F. Such frigid temperatures are one of the main factors that make the extreme space environments encountered on the Moon and elsewhere so extreme.

altRadiation is another main concern. “Radiation is always present in the space environment,” says Pellish. “Small to moderate solar energetic particle events happen regularly and extreme events happen less than a handful of times throughout the 7 active years of the 11-year solar cycle.” Radiation can corrupt data, propagate to other systems, require component power cycling, and cause a host of other harmful effects.

In order to explore places like the Moon, Jupiter, Saturn, Venus, and Mars, NASA must use electronic communication devices like transmitters and receivers and data collection devices like infrared cameras that can resist the effects of extreme temperature and radiation; otherwise, the electronics would not be reliable for the duration of the mission.

Technology Transfer

Since 1987, NASA has partnered with Huntsville, Alabama-based CFD Research Corporation (CFDRC), a company that specializes in engineering simulations and innovative designs and prototypes for aerospace and other industries. A few years ago, CFDRC received funding from Marshall Space Flight Center’s Small Business Innovation Research (SBIR) program to refine an existing software tool to predict the behavior of electronics in the cold, radiation-filled environment of space.

During the first phase of its work, in collaboration with Georgia Tech, CFDRC enhanced and demonstrated a technology called NanoTCAD for predicting the response of silicon-germanium (SiGe) semiconductor technology to radiation. During its second phase, the company demonstrated and validated NanoTCAD for temperature ranges from -382–266 °F.

Marek Turowski, the director of the nanoelectronic and plasma technology group at CFDRC explains how, as electronic parts become smaller, the effects of radiation and temperature become more severe. “When radiation particles bombard a microchip, it is like hail hitting a car,” he says.

Even though hail may not damage a large truck, the same hail could cause significant damage to a truck the size of a toy. Likewise, as electronic devices decrease in size, radiation particles can damage them more easily.

Being able to predict the behavior of nanoelectronics in the extreme space environment reduces the risk of failure during a critical NASA mission. Using NanoTCAD, designers can better evaluate performance and response of electronics early in the design stage, thereby reducing the costs and testing time involved. As Turowski explains it, “The purpose of NanoTCAD tools and models is to predict the behavior of electronics in space before they actually go to space. The prediction happens on the computer screen and accurately takes temperature and radiation into account.”

Pellish says NanoTCAD has already been used to evaluate key technologies for the Ice, Cloud, and land Elevation Satellite-2 (ICESat-2), scheduled for launch in 2016. ICESat-2 will look at polar ice, sea-level change, vegetation canopy height, and climate. “The NanoTCAD research on SiGe semiconductor technology processes provided a portion of the necessary insight into this technology so that it can be used in space,” he says.


Benefits

altNanoTCAD software is now available from CFDRC as a nanotechnology computer aided design (CAD) tool to predict the effects of extreme thermal and radiation environments on electronic systems. It is also used by CFDRC in its modeling and simulation services provided to the aerospace industry. The “nano” part of the product’s name means the software can address nano-size devices while “TCAD” stands for “technology computer aided design.”

“It solves basic physics equations,” says Turowski. “It looks at how electrons flow, how fields inside the devices behave, and how the varying temperature affects their behavior.”

Today, CFDRC’s NanoTCAD customers include electronic chip designers at Georgia Tech and Vanderbilt University. The electronics, chips, circuits, and devices that the universities are modeling with NanoTCAD are often for NASA missions. The European Space Agency and the Japanese Aerospace Exploration Agency are also potential customers of CFDRC’s NASA-improved technology.

The tool is also being employed for Department of Defense applications for space communication and surveillance systems for satellites. Entities like the Air Force and Navy design electronics that can suffer the same problems as NASA spacecraft. CFDRC also uses NanoTCAD to provide modeling, simulations, and radiation-hardening design services to national nuclear laboratories and commercial satellite designers.

According to CFDRC, the technology has led to approximately $2 million in revenue for the company, created new jobs, and led to partnerships with other defense and industrial customers.

“NASA has given us the opportunity to develop valuable technology,” says Turowski. “Now the technology is being adapted and enhanced for every new generation of electronics.”

Whether it is for the Moon, on-orbit, or other applications, CFDRC’s work with NASA is helping to make future space missions possible.

Simulation Packages Expand Aircraft Design Options

NASA Technology

When engineers explore designs for safer, more fuel efficient, or faster aircraft, they encounter a common problem: they never know exactly what will happen until the vehicle gets off the ground.

“You will never get the complete answer until you build the airplane and fly it,” says Colin Johnson of Desktop Aeronautics. “There are multiple levels of simulation you can do to approximate the vehicle’s performance, however.”

altWhen designing a new air vehicle, computational fluid dynamics, or CFD, comes in very handy for engineers. CFD can predict the flow of fluids and gasses around an object—such as over an aircraft’s wing—by running complex calculations of the fluid physics. This information is helpful in assessing the aircraft’s aerodynamic performance and handling characteristics.

In 2001, after several years of development, NASA released a new approach to CFD called Cart3D. The tool provides designers with an automated, highly accurate computer simulation suite to streamline the conceptual analysis of aerospace vehicles. Specifically, it allows users to perform automated CFD analysis on complex vehicle designs. In 2002, the innovation won NASA’s Software of the Year award.

Michael Aftosmis, one of the developers of Cart3D and a fluid mechanics engineer at Ames Research Center, says the main purpose of the program was to remove the mesh generation bottleneck from CFD. A major benefit of Cart3D is that the mesh, or the grid for analyzing designs, is produced automatically. Traditionally, the mesh has been generated by hand, and requires months or years to produce for complex vehicle configurations. Cart3D’s automated volume mesh generation enables even the most complex geometries to be modeled hundreds of times faster, usually within seconds. “It allows a novice user to get the same quality results as an expert,” says Aftosmis.

Now, a decade later, NASA continues to enhance Cart3D to meet users’ needs for speed, power, and flexibility. Cart3D provides the best of both worlds—the payoff of using a complex, high-fidelity simulation with the ease of use and speed of a much simpler, lower-fidelity simulation method. Aftosmis explains how instead of simulating just one case, Cart3D’s ease of use and automation allows a user to efficiently simulate many cases to understand how a vehicle behaves for a range of conditions. “Cart3D is the first tool that was able to do that successfully,” he says.

At NASA, Aftosmis estimates that 300–400 engineers use the package. “We use it for space vehicle design, supersonic aircraft design, and subsonic aircraft design.”

Technology Transfer

To enable more use of Cart3D for private and commercial aviation entities, the Small Business Innovation Research (SBIR) program at Langley Research Center provided funds to Desktop Aeronautics, based in Palo Alto, California, to build a plug-in to Cart3D that increases the code’s accuracy under particular flow conditions. Aftosmis says Desktop Aeronautics delivered valuable results and made Cart3D more applicable for general use. “Now they are bringing the product to market. This is something we never would have had the time to do at NASA. That’s the way the SBIR process is supposed to work.”

In 2010, Desktop Aeronautics acquired a license from Ames to sell Cart3D. The company further enhanced the software by making it cross-platform, incorporated a graphical user interface, and added specialized features to enable extra computation for the analysis of airplanes with engines and exhaust.

“I think it’s going to be game-changing for CFD,” says Aftosmis. “Cart3D is the only commercial simulation tool that can guarantee the accuracy of every solution the user does.”


Benefits

altToday, Desktop Aeronautics employs Cart3D in its consulting services and licenses the spinoff product to clients for in-house use. The company provides commercial licenses and academic licenses for research and development projects.

The software package allows users to perform automated CFD analysis on complex designs and, according to the company, enables geometry acquisition and mesh generation to be performed within a few minutes on most desktop computers.

Simulations generated by Cart3D are assisting organizations in the design of subsonic aircraft, space planes, spacecraft, and high speed commercial jets. Customers are able to simulate the efficiency of designs through performance metrics such as lift-to-drag ratio.

“It will assemble a spectrum of solutions for many different cases, and from that spectrum, the cases that perform best give insight into how to improve one’s design,” says Johnson. “Cart3D’s preeminent benefit is that it’s automated and can handle complex geometry. It’s blazing fast. You push a button, and it takes care of the volume meshing and flow measurement.”

Without building an aircraft, engineers can never be completely certain which design concept will perform best in flight. However, they now have a tool to make the most informed prediction possible.
