Abstract
A monitor-exercise equipment apparatus for measuring a biomedical response such as heartbeat rate, and for using the measured response to control the exercise equipment, where the monitor includes a transmitting unit and a receiving unit located in the exercise equipment. The monitor detects a biomedical response (heart rate) and produces a digital pulse train representing this response. The digital pulse train is then encoded to produce an encoded digital signal having a first identification part identifying the transmitting unit and a second data part representing the person'"'"'s biomedical response. This encoded digital signal is wirelessly sent to the receiving unit which reads the received signal to determine if it is from the transmitting unit. If it is from that transmitting unit, the data part is read. If there are too many errors in the data part, a new frequency of wireless transmission is used in the monitor. If the errors are within a reasonable bound, the data bits representing the biomedical response are sent to a memory and/or a display. If the received signal were not from the correct transmitting unit, the received signal is rejected. Interference from other monitors or electrical equipment is minimized, and the data displayed is very accurate. The receiving unit provides a signal to a parameter control means in the exercise equipment. The parameter control means automatically regulates the resistance offered to the user in accordance with the measured heart rate of the user to provide a proper workout. Memory is included for providing exercise profiles unique to the user. An identification unit allows each user to identify himself/herself to the equipment to access the proper stored exercise profile for that person.
