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.

Natural Technology for Food Preservation

Technologies are sought that will provide a natural method for extending shelf life, the prevention of food deterioration (oxidation and/or spoilage), and growth of pathogenic micro-organisms along the full chain of fresh or processed food. The solution could be effective at any stage, from feedstock to point of processing, through to consumer use. It could be a new natural preservative (plant extract, food-grade cultures), natural process/additive for enhancing the activity of existing known natural preservatives, or antimicrobial films or coatings.

Gripping Hand or Chuck Technology for Automated Applications

A company is seeking unique technologies for automated hand, chuck, and grip product assembly applications (not CNC machining). Multiple sizes of gripping device are acceptable for different sized parts. The chuck or hand technology should be general purpose in nature, and show versatility in its ability to grip or manipulate parts of various forms and shapes in order to be applicable to a wide range of assembly processes.

Dispelling Light Sources

Philips is offering an innovative technology to dispel humans (and animals) from an area where they are unwanted. The new and patented dispelling light source (DLS) concept is based on disturbance of humans and/or animals using photosensitive stimuli. When switching a DLS system to the specifically programmed flickering mode, it directly induces negative psychological and/or physiological effects such as aversion, discomfort, dazzling, disorientation, fear, or malaise. As a direct result, humans and/or animals will be dispelled from the site. Proper selection of the flicker frequency avoids triggering of photosensitive epilepsy. DLS-suitable lighting systems comprise high-pressure gas discharge lamps, where the high-pressure sodium lamp exhibits a particular provocative effect. A strong feature of DLS systems is its dual-mode operation: the system operates in the normal application-dependent illumination mode until the system driver is externally triggered by a proximity detector. Once humans and/or animals have been dispelled, the system switches back to normal lamp operation. Get the complete report on this technology at: Email: nasatech@yet2.com Phone: 781-972-0600

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.
