Generic Helicopter-Based Testbed for Surface Terrain Imaging Sensors

This flexible field test system is designed for sensors that require an aerial test platform. To be certain that a candidate sensor system will perform as expected during missions, we have developed a field test system and have executed test flights with a helicopter- mounted sensor platform over desert terrains, which simulate Lunar features. A key advantage to this approach is that different sensors can be tested and characterized in an environment relevant to the flight needs prior to flight. Testing the various sensors required the development of a field test system, including an instrument to validate the “truth” of the sensor system under test. The field test system was designed to be flexible enough to cover the test needs of many sensors (lidar, radar, cameras) that require an aerial test platform, including helicopters, airplanes, unmanned aerial vehicles (UAV), or balloons. To validate the performance of the sensor under test, the dynamics of the test platform must be known with sufficient accuracy to provide accurate models for input into algorithm development. The test system provides support equipment to measure the dynamics of the field test sensor platform, and allow computation of the “truth” position, velocity, attitude, and time.

Induction Charge Detector With Multiple Sensing Stages

Standard errors and detection limits are reduced by use of multiple stages. An induction charge detector with multiple sensing stages has been conceived for use in characterizing sprayed droplets, dust particles, large ionized molecules, and the like. Like related prior single-stage devices, each stage yields a measurement of the electric charge and the time of flight of the particle. In effect, an n-stage sensor yields n independent sets of such measurements from the same particle. The benefit of doing this is to increase the effective signal- to-noise ratio and thereby lower the charge-detection limit and the standard error of the charge measurement.

Dr. John Mather, Chief Scientist for the Science Mission Directorate

NASA Headquarters, Washington, DC Using NASA’s Cosmic Background Explorer (COBE) satellite to measure microwaves and infrared light that originated with the formation of the universe, Dr. John C. Mather helped verify the validity of the Big Bang theory. Recently named to head up the Office of the Chief Scientist for the Science Mission Directorate at NASA Headquarters in Washington, DC, Dr. Mather was a co-recipient of the 2006 Nobel Prize in Physics.

Microwavable Packaging That Produces Authentic Grilled Foods

This organization wants to create authentic grilled foods in a home microwave oven with typical microwave food preparation times and convenience. Authentic grilled foods combine a slightly charred taste with a less fatty, cleaner feel, and the appearance of grill marks seared by high heat into the surface of the food. This need seeks to reproduce as closely as possible the texture and quality of perfectly grilled foods. Respond to this TechNeed at: Email: nasatech@yet2.com Phone: 781-972-0600

Pharmaceutical Processing Technologies

A company seeks a range of new processing and preparation technologies for use in pharmaceutical preparation. Such technologies may enhance current chemistry processes such as finer milling that leads to faster in-process reactions. Technologies may be applicable to a variety of pharmaceuticals after preparation, such as techniques for better tabletforming, encapsulation techniques, or techniques for preparation of non-traditional delivery mechanisms.

Non-Bitter Peptide

In a two-step process of hydrolyzation utilizing fungal proteases, mild peptide is extracted in such a way that it is free of the bitter taste and aftertaste of similar products. Mild peptide may be mixed with protein drinks and other products to increase the effectiveness of the protein through its amino acid profile and its high Protein Efficiency Ratio. The process of producing mild peptide also makes it non- allergenic, which means it can be used as a milk substitute in infant formulas and by anyone who is lactose-intolerant. Another benefit of the mild peptide production process is that the resultant protein retains its full nutritional value and is quickly absorbed to enhance performance and well-being.
