A Black Box for People
lightwaveman writes "Developed for astronauts, a small device called 'the CPOD' does for people what black boxes do for airplanes. It's a compact, portable, wearable device -- a single piece of equipment that gathers a wide variety of vital signs. About the size of a computer mouse, a CPOD is worn around the waist. It's comfortable enough to be worn while sleeping. It's non-invasive. It takes only minutes to don. Importantly, it can track a person's physiologic functioning as they go about their normal routine -- they don't have to be tethered to some stationary device. It can store data for eight-hour periods for later downloading; alternatively, it can send it wirelessly, in real time, to some other device."
Sounds very much like the Medical Mood Ring.
Imagine the US postal cycling team support car having stats in real time on all of the cyclist during the tour de france.
No need to imagine - Team USPS has been using heart rate monitors for years, not to mention being in constant radio contact with their director. All of the other teams do this, too.
