The Medtek 420 is approved for use in emergency medical evacuation helicopters. A later invention, the Medtek 420, adjusts for air pressure and surrounding noise. The Medtek 410 took the guesswork out of monitoring a patient’s vital signs, allowing medical professionals to diagnose and treat patients. Michael Croslin (b.1933) invented computerized blood pressure and pulse monitoring devices called the Medtek 410 and 420. The camera also found hydrogen in deep space, which led to new ideas about the birth of stars in the universe. This allowed them to develop new ways to control air pollution. The camera used ultraviolet light, invisible to the naked eye, to capture high-quality images of Earth.Ĭarruthers's invention helped scientists see how air pollution forms. It was plated in gold and carried aboard the Apollo 16 mission, where it was placed on the moon's surface. George Carruthers (b.1939) invented the far ultraviolet camera/ spectrograph in 1969. Boykin worked in Chicago, Illinois, and in Paris, France. He invented a machine used to control heart pacemakers, parts for guided missiles and computers, an electronic air filter, and a cash register that thieves couldn't break into.
