At-Home Medical Diagnostic and Monitoring Technologies

New home-use and point-of-care diagnostic medical technologies are needed. The diagnostics kits should monitor diseases not easily measured. Testing may be done within the device, or the device may be a tethered testing head that reports to a central diagnostics facility. The product can be tethered via phone, cell phone, or Internet, for example. A sample may also be prepared by the device and physically delivered to a central testing service. Areas of interest include cardiac, cholesterol, digestive health, lung function, osteoporosis, and progressive neuropathy.

Fast-Charge Technology Finds Battery “Sweet Spot”

A technology recharges batteries in up to one-tenth the time of conventional methods. The device creates conditions within the battery that allow power to be input as fast as the cell can accept the charge. By creating a charging “ecosystem,” the optimum battery charging conditions are present which, in turn, cause the necessary redox reactions to occur at a very fast rate, with little to no side reactions occurring from an input of excess energy.

Technology Produces Electrically Conductive Polyester

New polyester compositions feature desired electrical characteristics without unduly deteriorating the other valued melt viscosity, processing, and shaped article properties. The electrically conductive polyester has strong conductivity at low carbon black loading. The use of carbon black with specific physical properties is critical for achieving the desired mix of electrical and processing traits. The carbon black component may be added at the monomer stage, such as with the dicarboxylic acid or with the glycol, or to the initial (trans)esterification product.

Friction Reduction of Steel Surfaces

A global organization needs innovative technologies that will decrease the surface friction between steel surfaces. Thin, 0.2-mm steel components must come into shear contact with each other, resulting in slip, wear, and heat. The components are lubricated to reduce friction. Any proposed solution must have some degree of flexibility, by a radius between 50 and 100 mm. The non-rigid technology should be unaffected by a shear force of 50 N, or operating temperatures of -20 to +180 °C.

Improved Efficiency of Jet Engines

By minimizing the distance between the rotating vanes of a turbine and the static case structure housing the rotating blades, a client seeks to improve the efficiency of jet engines. Eliminating system leakage is essential to providing the most amount of energy for the lowest cost. The compressor fans of a turbine engine must maintain extremely tight tolerances to reduce leakage around the vanes. Minimizing leakage, a critical task given the smaller features of the vane and rotor geometry, is a particular challenge because of the jet engine’s high pressures and temperatures.

Aeronautics Test Program

NASA Dryden Flight Research Center (DFRC) is one of four NASA centers that supports NASA’s Aeronautics Test Program (ATP). The ATP ensures the long-term availability and health of NASA’s major wind tunnels, ground test facilities, flight operations, and test infrastructure that support NASA, Department of Defense, and U.S. industry research and development (R&D), and test and evaluation (T&E) requirements.

Technologies for Large-Scale Numerical Simulation

NASA Ames Research Center is home to the world’s seventh most powerful supercomputer, Pleiades. Named after the star cluster, it represents NASA’s state-of-the-art technology for meeting the agency’s supercomputing requirements, enabling NASA scientist s and engineers to conduct modeling and simulation for NASA missions. As one of the most powerful general-purpose supercomputers ever built, Pleiades has the computing power equivalent to that of 41,000 MacBook Pros.
