Eighteen-year-old inventor Ryan Patterson is truly a young scientist. He designed a sign language translator glove that works by sensing the hand movements of the American Sign Language and sending the data to a device that displays the words on-screen. The glove allows a deaf person to communicate easily with anyone. Ryan's invention won first place in the Siemens Westinghouse Science and Technology competition!

Tammy Reid Bush is a bioengineer who specializes in seating. Tammy helped develop items such as office chairs using motion measurement devices to determine the most comfortable and supportive seating for each individual. This same premise is being used in automobiles and wheelchairs, and Tammy's goal is to have "healthy" seats at schools, on planes, and everywhere!
