A new device for football helmets warns of the dangerous spikes in body temperature associated with heatstroke. The device consists of a rugged sensor (the black object visible at the left side of the helmet), encased in a headband or helmet cushion, and a transmitter that beams temperature readings wirelessly to a PDA on the sidelines. If the wearer’s body temperature reaches and sustains a reading of 39 °C for more than 20 seconds, an alarm goes off on the PDA.
