Technology Uses In-Building Wi-Fi to Determine Location of Wireless Devices

LOCADIO technology pairs readings of IEEE 802.11× received signal-strength indication (RSSI) with probabilistic analysis of building floor plans to deduce where a wirelessenabled device is in a building. It can locate a wireless device within a room to an accuracy of about 1.5 meters. LOCADIO is “hardware-agnostic” in that it is not tethered to any specific brand of system hardware. LOCADIO complements GPS and RFID technologies, in that it operates indoors, can be implemented for a relatively few wireless-enabled devices, and works at ranges greater than RFID.

Centennial Challenges

The NASA Regolith Excavation Cha llenge was held on August 2 and 3 on the campus of the California Poly - technic State University in San Luis Obispo, CA. The competition required teams to build a roving excavator that could autonomously navigate, excavate, and transfer 150 kg of simulated lunar regolith (lunar soil) into a collector bin within 30 minutes. Excavating lunar regolith will be an important part of any construction projects or processing of natural resources on the Moon. NASA is looking for new ideas for excavation techniques that do not require excessively heavy machines or large amounts of power.

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.

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.

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.

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.
