Biomedical response monitor and method using identification signal

DETAILED DESCRIPTION This invention broadly relates to exercise equipment that uses an improved technique and monitor for measuring and displaying, preferably on a continuous basis, a physical condition or biomedical response, such as a heartbeat rate.
The monitor includes a transmitter unit for producing an encoded digital signal representing the biomedical response and for wirelessly transmitting the encoded digital signal to a receiver unit for display of the measured biomedical response.
The monitor also includes a detection means for detecting errors in the received encoded digital signal, and correction means for automatically changing the transmitter unit and the receiver unit to provide accurate wireless transmission therebetween of the measured biomedical response.
In a preferred embodiment this monitor includes unique identification between a transmitter and an associated receiver.
This monitor is particularly suitable for personal use such as would occur in a home or office or even in a gym or fitness center where it can be a part of exercise equipment.
In one embodiment, the transmitter unit is adapted to be worn and would be battery operated while the receiver unit can be part of exercise equipment and can be used to control a workout in response to a measured biological response.
As long as the receiver is within the transmission distance from the transmitter, it will receive the wirelessly transmitted signal.
In one aspect of this invention the monitor measures a person's heartbeat and displays an indication of the monitored heartbeat.
In this embodiment, the apparatus is comprised of a sensor-transmitter unit (chest unit) adapted to be worn in contact with a person's chest and having electrodes which receive the person's ECG signal.
This signal is amplified and digitally encoded to contain an identification portion and a data portion.
This encoded signal is transmitted in a wireless manner to a receiver-display unit (wrist unit), where the receiver-display unit contains a display for displaying the person's heartbeat
