If you hate getting poked and prodded for a medical exam, you're not alone. I've always been envious of the crew on Star Trek; they made it look so easy as Dr. Crusher waved a tricorder over her patients for an instantaneous exam. The tricorder is like a medical diagnostic magic wand; it was assumed to be fictional, until now. The Cloud DX is the first prototype to be revealed for the Tricorder XPrize competition. The device is designed to diagnose 15 different medical conditions and can monitor vital signs for 72 hours.
