Lightening the Load of Recovery

A unique treadmill, invented by a NASA scientist, supports people trying to get back on their feet. Ask the Denver attorney whose legs were smashed in a car accident. Ask the veterans rehabilitating from injuries sustained while defending the nation. Ask NBA star Blake Griffin, or NFL safety Jim Leonhard, both of whom endured leg injuries playing their sports. Ask U.S. soccer pro Charlie Davies, who returned to the field only a month after suffering life-threatening trauma in a car crash. All will tell you about the benefits of NASA-derived technology.

Determining Key Isotopic Ratios In The Field

On August 6th, 2012 the automatic Mars Science Laboratory rover named Curiosity landed on Mars. One of the scientific instruments on board is ChemCam, which has a pulsed laser capable of ablating a focused spot on a remote sample to create a glowing plasma plume of target material. Light from plasma is collected by rover’s telescope on a mast, and the optical spectra are then analyzed by an internal spectrometer. ChemCam can take thousands of spectra per day from a distance of about 7 meters, thus making chemical analyses on the surface of Mars with unprecedented speed. Operationally, the ChemCam data facilitates decisions of where the rover should be driven.

Using Laser Direct Structuring (LDS) to Create Robust Hardware Security Devices

Awide range of devices are designed to handle, convey and store sensitive information that requires varying degrees of security from protecting low level administrative to classified and top secret information. In addition, the information and data can reside in an equally wide range of locations and environments from protected and guarded facilities to unsecure desks and offices and over a wide range of environmental conditions including temperature, humidity, shock and vibration.

VPX-SC N-dimensional Supercomputing Architectures Come To The Critical Embedded Systems Market

From the first computers of the 1940s through the machines of the 1990s, all computer systems were CPUbound. In other words, the I/O interfaces could deliver more data than the CPU could process. In the 1990s Moore’s Law took over and clock speeds doubled every 18 months, along with the addition of multi-core processors. So, from 1990 through today, we have been I/O-bound, meaning CPUs can now process more data than the I/O links can deliver. Increases in CPU performance have been revolutionary while the increases in interconnect bandwidth have been incremental for many decades. However, bandwidth increases in RapidIO, InfiniBand, and Ethernet are breaking this bottleneck, giving us the ability to design incredibly powerful embedded supercomputing architectures for today’s dataintensive applications.

Do-It-Yourself Additives Recharge Auto Air Conditioning

NASA spinoff can help your car keep its cool. Having your car’s air conditioner lose its cool on a hot day can make for an uncomfortable ride. A breakdown in thermal control in space is far more than a matter of comfort; on the Moon, for example, the temperatures can reach a scorching 260 °F during the day. In planning for future space missions, NASA aimed to improve the thermal control systems that keep astronauts comfortable and cool while inside a spacecraft.
