Abstract:
A method for measurement of heartbeat rate, comprising the steps of:detecting a person's heartbeat signal;forming a pulse train having a data portion corresponding to said person's heartbeats using said heartbeat signal, an identification portion indicative of identification of a transmitter-receiver pair including a transmitter for wirelessly transmitting said pulse train from said transmitter to a receiver;wirelessly transmitting said pulse train from said transmitter to said receiver;receiving said pulse train in said receiver;using said identification portion to identify said pulse train as coming from said transmitter, even in the presence of interference;calculating said heartbeat rate in said receiver using said received pulse train, if said pulse train is from said transmitter;rejecting said pulse train in said receiver if said pulse train is not from said transmitter, and displaying said heartbeat rate.
