The aptly-named "Jonah" pill contains a wireless temperature sensor to remotely monitor your vital signs. The pill is part of the VitalSense physiological monitoring system designed by the Mini Mitter Company in collaboration with the US Army.
"VitalSense proved to be a real lifesaver in a recent study of wildland firefighters in Montana. The study was designed to evaluate heat stress in high intensity work environments. Canadian coaches used VitalSense to evaluate the physiological status of Canadian triathletes training for all three legs (swimming, biking and running) of their event in the 2004 summer Olympics. In another athletic related study, Nike® is using VitalSense to test heat dissipation in clothing."
