Abstract:
1. A heart rate monitor, comprising: a receiver which receives wireless signals which include a plurality of pulses, the plurality of pulses include at least pulses from a transmitter worn by a first user which represent heart beats of the first user, and pulses from a transmitter worn by a second user which represent heart beats of the second user, where the pulses from the transmitter worn by the second user are unwanted cross-talk; at least one micro-controller associated with the receiver, the at least one micro-controller associates a peak amplitude with each of the plurality of pulses, determines an amplitude range based on at least one of the plurality of pulses, includes pulses of the plurality of pulses whose associated peak amplitude is within the amplitude range as being candidate heart beats of the first user, determines a heart rate of the first user based on one or more of the candidate heart beats, and excludes pulses of the plurality of pulses whose associated peak amplitude is below the amplitude range from being used to determine the heart rate of the first user; and at least one display device associated with the at least one micro-controller, the at least one display device displays the heart rate of the first user.
