Lunar Science Instrumentation: Understanding and Characterizing the Moon Through Challenging Measurements

NASA lunar robotic science missions support the high-priority goals identified in the 2007 National Research Council report, The Scientific Context for Exploration of the Moon: Final Report (National Academies Presses, 2007). Future missions will characterize the lunar exosphere and surface environment; field-test new equipment, technologies, and approaches for performing lunar science; identify landing sites and emplace infrastructure to support robotic and human exploration; demonstrate and validate heritage systems for exploration missions; and provide operational experience in the harsh lunar environment.

Irrigation Water Extracted from Air and Soil Moisture Through Solar Power

By condensing water from the air and soil on chilled pipes, this invention attempts to alleviate both water and food shortage problems. It offers the ability to produce agricultural crops in most hot and humid climates by watering plants with condensation from environmental moisture, and by multiplying the number of crops that can be obtained per season. The production of condensation on pipes’ surfaces irrigates the plants’ roots, cools the roots, and accelerates the plants’ growth.

Aircraft Support Via a Vortex-Ring Cushion Projector

An all-terrain, multi-role, hover-capable aircraft has a fuelefficient, rugged, vertical take-off and hover propulsion system. A raised-height, dispersal-resistant hover cushion is projected over the ground by the device as two bisected concentric streams of rotating and counter-rotating torus flume rings. The aircraft is able to clear trees and obstructions above terrain that would be prohibitive for a hovercraft.

Wireless Communication for Factory Automation

A company seeks technology that is applicable to automated assembly lines; specifically, a reliable and fast short-range wireless technology that can take the place of wired connections for robots and factory automation equipment. Equipment with appendages in motion, such as robots, is fundamentally different in its wiring requirements from equipment that is static. A possible solution to the abrasion that results from repeated movements is to provide control through wireless communication.

Platform Technology for Electromechanical Position Sensor

This technology provides an efficient and cost-effective way to measure absolute position in one or two dimensions using a new Point Coupled Linear Transformer (PCLT). The PCLT detects movement and position on flat or curved surfaces. The nature of its design provides the sensor with excellent linearity, its DC output voltage allowing it to be used as a direct drop-in replacement for other position sensors. To date, inductive sensors (LVDT/RVDT/LVIT) have dominated the market, but they have certain limitations that can be overcome by this new technology. Namely, PCLTs can be used to measure a position on flat or curvilinear surfaces, and can also be extended to 2D measurements, whereas LVDTs are limited to 1D position sensing. PCLT also has a 90% stroke-tolength range, which is 30% better than LVDTs. This could result in a 30 to 60% weight reduction of the sensor.
