Signal Processing Software for Remote Vital Sign Monitoring

NASA’s Jet Propulsion Laboratory, Pasadena, California This software provides the processing for a non-contact system that remotely estimates the heart rate and respiration rate of individuals as they carry on daily activities, and also enables detection of heart and respiration rate through walls.

Versatile Platform for Nanotechnology Based on Circular Permutations of Chaperonin Protein

Circular permutation is used to join peptide sequences within a protein template. Ames Research Center, Moffett Field, California The controlled organization of inorganic materials into multi-dimensional addressable arrays is the foundation for logic and memory devices, as well as other nonlinear optical and sensing devices. Many of these devices are currently fabricated using lithographic patterning processes that have progressively developed toward greater integration densities and smaller sizes. At submicron scales, however, conventional lithographic processes are approaching their practical and theoretical limits. At scales below 100 nm, ion and electron beam lithography becomes prohibitively expensive and time consuming, and more importantly, at these scales, quantum effects fundamentally change the properties of devices.

Zero-G Condensing Heat Exchanger with Integral Disinfection

The proposed concept promises to improve the life support environment for astronauts. John H. Glenn Research Center, Cleveland, Ohio A concept for a unique zero-g condensing heat exchanger that has an integral ozone-generating capacity has been conceived. This design will contribute to the control of metabolic water vapor in the air, and also provide disinfection of the resultant condensate, and the disinfection of the air stream that flows through the condensing heat exchanger.

Concurrent O2 Generation and CO2 Control for Advanced Life Support

Lyndon B. Johnson Space Center, Houston, Texas A life support system generates oxygen in low oxygen and/or hazardous environments such as mining, chemical/biological attacks, nuclear fallout, or space exploration. Based on proven technology, this O2/CO2 control system has the potential to significantly reduce the mass of the oxygen carried into the low oxygen and/or hazardous environment by continuously regenerating the oxygen used by the human subject(s).

Gene Expression Signatures for Colon Carcinogenesis and Radiation-Induced Cellular Transformation

Lyndon B. Johnson Space Center, Houston, Texas Monitoring colon health and transformation into a diseased tissue, including inflammation and cancer, is difficult using conventional techniques, as individuals are required to undergo invasive procedures. However, by using exfoliated cells, it is possible to characterize the overall health of the colon by monitoring patterns of gene expression.

Tissue-Building Technique Could Someday Build Organs

A new instrument developed at Brown University could someday build replacement human organs the way electronics are assembled today. In this case, the parts are 3D microtissues containing thousands to millions of living cells. The device is called “BioP3” for pick, place, and perfuse. Because it allows assembly of larger structures from small living microtissue components, future versions of BioP3 could be used to manufacture organs such as livers, pancreases, or kidneys.
