BOSTON (AP) - Elwood "Woody" Norris doesn't let conventional thinking stand in the way of his inventions.
To cut down on manmade sound straying beyond its intended audience, Norris developed a way to create a focused beam of sound waves, sort of like focusing a beam of light.
To put flight within reach of people lacking time and money to invest in pilot training, Norris helped create a simple-to-fly, ultralight helicopter.
