Probing Sport and Control

Wired reports on the latest control mechanism from the labs (via Defense Tech):

When your core body temperature gets out of whack - even 1 degree outside the normal range - it could be a sign of medical distress. But getting an accurate reading usually requires, ahem, a rectal probe. That's not exactly convenient when trying to monitor a GI scrambling across a desert combat zone or a linebacker during a preseason scrimmage. Oregon medtech firm Mini Mitter has a less intrusive device: a pill-sized, swallowable thermometer called Jonah that transmits data wirelessly to a handheld. Jonah lasts from one to five days, depending on stomach contents and, ahem again, how things are moving down there.

Similar monitors already exist; doctors use them to inspect the small intestine, and John Glenn tried one out on his '98 shuttle trip. But the new models are more reliable and can transmit up to 3 feet. The Army's elite Rangers and three NFL teams are using them during training.
