Large Aperture Inflatable/Deployable Antennas and Their Role in NASA’s Vision for Space Exploration and Earth Science

As NASA evolves its vision for space exploration and Earth science, greater demands are placed on advanced communications and sensing systems to allow for higher data-rate communications from the Moon, Mars, and beyond, as well as for more precise Earth and planetary remote sensing activities. Taking into consideration the cost of launching hardware into space (about $20K per kg), as well as the fairings’ volume limitations, there is need for novel antenna technology concepts to circumvent these limitations, without jeopardizing the desired capabilities. To address this scenario, NASA is investigating the development of large aperture, inflatable/deployable antenna (IDA) technologies as a viable option to fulfill the aforementioned requirements. Attainment of these requirements demands overcoming a series of critical challenges as discussed below.

Converting High-Molecular-Weight Polymer Emulsions Into Dry Form

A company that supplies chemicals, including inverse emulsions that consist of a very high- molecular-weight, water-soluble polymer dispersed in a continuous oil phase, is seeking technologies that can convert these emulsions to powdered form without losing any of the polymer properties. Known technologies include spray-drying and precipitation. Precipitation processes are based upon the water and oil being soluble in some polar solvents, while the high-molecular- weight polymer is insoluble in these solvents.

Anti-Itch Non-Steroidal

A company is seeking technology (synthetic actives, natural actives, delivery systems) to eliminate itch for a variety of indications for over-the-counter applications; specifically, actives and/or delivery systems that will relieve itching. The technology should eliminate itching for a significant period of time (i.e. several hours, minimum). Alternatively, immediate relief (within 60 seconds) would be of interest. Any formulation is acceptable, but oral delivery or physical barrier approaches will not be considered. Respond to this TechNeed at: Email: nasatech@yet2.com Phone: 781-972-0600

Password Protection System Requires No Special Hardware

The High-Security Password System takes the place of strong passwords on digital devices and online services, yet is easy to remember and quick to enter for most individuals. This system places images in a two- or three-dimensional matrix to generate the equivalent of a ten-digit number. The security of the system can be increased by cells in the matrix, also consisting of a number of cells.

Catalytic Filters for Outdoor Power Equipment

NoxFox™ Catalytic Filters reduce harmful emissions from engine exhaust with performance comparable to existing catalytic converters. High-surface-area ceramic nanofibers hold nanoparticles of platinum, palladium, rhodium, and other catalysts, so that NoxFox catalytic filters are comparatively lightweight and robust. Patented, catalyzed ceramic nanofibers (nCATfibers™) provide high surface area for maximal contact and minimal exhaust resistance. Engine makers can use NoxFox catalytic filters do the job not possible by engine tuning and deliver a highly “green” product. In addition, the product’s unique structure results in a 50% weight reduction over existing honeycomb catalytic converters.

Energy Storage Technology to Power the Future in Space Exploration

By Carolyn Mercer, NASA Glenn Research Center, Cleveland, OH NASA is focused on building a human outpost on the lunar surface. To reach this goal, there is a critical need to develop energy storage technologies to power the future lunar outpost. In particular, technology is required for outpost power generation for the lunar lander that will deliver outpost hardware, and for advanced extravehicular activity (EVA) suits. In every case, human-safe, reliable operation and low mass are critical to ensure the viability of extended stays on the lunar surface while minimizing the launch mass and the mass carried by astronauts and lunar rovers.

Image Processing for Controlling a Robot or Quality Inspection

A company seeks technologies that may be applicable to automated assembly lines, including a robot to use image processing to select and pick up small parts from a bin using a pin several millimeters in diameter. The image processing technology should be general-purpose and highly versatile to allow the techniques to be applied to many different situations. The required picking speed is several seconds. Possible solution areas are 3D medical imagery and automated surgical equipment. Respond to this TechNeed at: Email: nasatech@yet2.com Phone: 781-972-0600
