I am curious about the structure of heart-rate monitors used by atheletes (a strap on chest with a transmitter & a receiver in a handheld computer). The ones that Polar or Sigma sports produce.
Does anyone has an idea what are the specs of the receiver/transmitter? Do you think they use their own sytems or use some standard? How is the heart rate monitored by a sensor in a strap?
