38. Image-processing technology used remove defects due to image jitter, image rotation and image zoom in video sequences. Used by law enforcement agencies to improve crime-solving videos; doctors in medical imaging; scientific applications and even home video cameras.
39. Gas leak-detection system used by Ford in natural gas-powered car.
40. Method of labeling products with invisible and virtually indestructible markings - used on electronic parts, pharmaceuticals and livestock -- in fact it could be used on just about anything.
41. Fire resistant foam used as thermal and acoustical insulation in aerospace, marine and industrial products. Also used as for fire barriers, packaging and other applications requiring either high-temperature or very low-temperature insulation. Used by Boeing, Lockheed-Martin, and Airbus for for major weight savings in aircraft.
42. Hand-held camera which firefighters use to pinpoint the hotspots of wildfires.
