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

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.

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.

NASA’s Science Mission Directorate’s Sensor, Detectors, and Instrument Technology Needs

The Science Mission Directorate (SMD) engages the Nation’s science community, sponsors scientific research, and develops and deploys satellites and probes in collaboration with NASA’s partners around the world to answer fundamental questions requiring the view from and into space. The National Research Council is an advisor to SMD and conducts decadal surveys to define science priorities in its discipline areas for the next decade. SMD seeks to understand the origins, evolution, and destiny of the universe and to understand the nature of the phenomena that shape it. SMD also seeks to understand:

Environmentally Friendly Non-Stick Perfluoroalkyls

The C6 perfluoroalkyl formulation overcomes the environmental issues inherent in other perfluoroalkyl tails, and imparts non-stick properties and resistance to oil, grease, solvents, or water that are similar to C8 fluoroalkyl tails. Chemicals containing perfluoroalkyl tails are used for stain, water, oil, and grease resistance, and for their surfactant and non-stick properties. In a commercially available formulation used on a cellulose substrate, it resists oil and water penetration under either aggressive (hot polar fats) or non-aggressive conditions (ambient temperatures, non-polar oils), and is approved for paper treatment where the paper may be in contact with food.

High-Efficiency, Flexible, High-Stability Solar Cells

Nanotechnology-based hybrid nanocrystal inorganic thinfilm photovoltaics combine the best features of solar cells constructed from bulk thin-film silicon and from polymer solar cells. The colloidal nanocrystal (NC) cell technology offered here allows the production of air-stable solar cells processed using solution phase methods. The technology simplifies fabrication under ambient conditions, thus expanding the range of flexible or conformal substrates that can be used.

Measurement of Oxygen with Sub-PPM

A company is searching for an innovative technology for the measurement of oxygen with sub-ppm resolution. They are seeking a continuous method of measurement or those with cycle times measured in seconds, the ability to measure within a flammable gas such as hydrogen, and a non-consumable device with a long lifetime (greater than 5 years). Oxygen shock should not damage the sensor or require special treatment to recover it. Respond to this TechNeed at: Email: nasatech@yet2.com Phone: 781-972-0600
