AI Aids Medical Tricorder's Arrival -- 250 Years Early

Since I'm told that some of you may be unfamiliar with "Star Trek" lore, the tricorder was (will be?) a two-piece mobile medical diagnostic tool used by Dr. Leonard "Bones" McCoy, ship's surgeon of the United Star Ship (USS) Enterprise (NCC-1701), in "Star Trek: TOS" (The Original Series), which debuted on Sept. 8, 1966. The two pieces of the tool included a roughly two-inch-long cylinder that looked a lot like a salt shaker (it was), and a rectangular box with a screen. Its use usually precipitated Dr. McCoy's declaration of, "I'm a doctor, not a bricklayer," or something similar. In 2012, the Qualcomm Foundation decided to put up a $10 million purse to sponsor an Xprize contest to develop such a device. According to contest rules, the winning entry had to had to weigh no more than five pounds, diagnose at least 16 different conditions based on analysis of five vital signs, and be usable by anybody, without the help of a medical professional.
