Personal monitor and method using identification to minimize interference
First Claim
1. 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.

Abstract
A heartbeat rate monitor that uses a sensor to detect a person'"'"'s heartbeats and circuitry for providing pulses indicative of these heartbeats. A transmitter wirelessly transmits these pulses, along with an identification (ID) signal, to a receiver. The ID signal identifies the transmitter and can be pulses providing a code. In the receiver, a circuit uses the ID signal to determine if the received pulses are from the transmitter. If they are from the transmitter, the pulses representing heartbeats are used to calculate hearbeat rate. Any received signal from a source other than the transmitter is rejected in the receiver. If there is transmission interference, the monitor can calculate an approximate heartbeat rate. The frequency over which wireless transmission occurs can be changed by the person, or automatically by the monitor.
