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.

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.

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

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:

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

Method for Manufacturing Controlled Open-Cell Silicone Foam

A company is looking for a method to manufacture controlled, ultra-lightweight, open-cell silicone foam. The foam cells must have very similar size, and the foam must be very elastic with a water absorption coefficient of 300-400%. The company is looking for companies able to design or to license the process for controlling temperature cycle, curing time, and other main process parameters.

NASA Technology Prize Competitions – Summer 2008

NASA has a program of technology prizes currently consisting of seven competitions held throughout the year. The program, which began in 2005, is known as Centennial Challenges in recognition of the centennial of powered flight. In keeping with the spirit of the Wright Brothers and other American innovators, the Centennial Challenge prizes are offered to independent competitors who work without government support including small businesses, student groups and garage inventors. The prize competitions are targeted at a range of technical challenges that support NASA’s missions in aeronautics and space. The goal is to encourage novel solutions from non-traditional sources. In the Centennial Challenge program, NASA offers the prize money but each of the competitions is managed by an independent organization, sometimes with additional private sponsorship.
