    The sudden death of San Francisco 49er Thomas Herrion in August 2005, and the heat-induced death of Minnesota Viking Korey Stringer four years ago, have prompted NFL management to review training safety precautions.

    Three NFL teams are using the CorTemp body temperature monitoring system from HQ Inc. of Palmetto, Fla., to track players while they train. CorTemp was devised in the 1980s by the Johns Hopkins University in collaboration with NASA's Goddard Space Flight Center to monitor astronauts.

  • the pill

    Players swallow a capsule that contains a telemetry system, transmitting device and battery. While in the gastrointestinal tract, a crystal sensor vibrates at a frequency relative to the temperature of the body surrounding it.

    This produces a signal, harmless to the body, that can be picked up by an external data recorder. The pill stays in the body for 24 hours or more and the battery works for about seven days. The pills cost around $30 each, depending on volume purchased.
