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 condition such as heartbeats and produces a pulse train representing this response. The pulse train is then encoded to produce an encoded signal having a first identification part identifying the transmitting unit and a second data part representing the person's biomedical response. This encoded 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 the received signal is not from the correct transmitting unit, it is rejected. Interference from other monitors or electrical equipment is minimized, and the data displayed is very accurate.

Abstract: A monitor for measuring a biomedical response such as heartbeat rate, and an apparatus for using the monitor to control exercise equipment. The monitor includes a transmitting unit and a receiving unit which can be located in the exercise equipment. The heart rate is determined and a first signal that can be used to determine heart rate (or is related to heart rate) is produced. An encoded digital signal identifying the transmitting unit is also produced. These signals are wirelessly sent to the receiving unit which determines if the signals are from the transmitting unit. Only if that is so is the first signal used to determine heart rate. If there are too many errors in the measured heart rate a new frequency of wireless transmission is used. If the errors are within a reasonable bound, the heart rate is sent to a memory and/or display.

Abstract: A monitor for measuring and displaying a biomedical response such as heartbeat rate, including a transmitting unit and a receiving unit. The monitor detects the response (heartbeat) 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 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.
