(US5394879-A)      The monitor has a transmitting and receiving unit located in the exercise equipment. An encoded digital signal represents the heart rate and has a first identification circuit identifying the transmitting unit and a second data unit representing the person's heart rate. If there are too many errors in the data part, a new frequency of wireless transmission is used. If the errors are within a reasonable bound, the data unit is sent to a memory and/or display.    The receiving unit provides a signal to a parameter controller which regulates resistance offered to the user in accordance with the measured heart rate providing a proper workout. Memory provides exercise profiles unique to the user. An identification unit allows each user to identify with the equipment to access their proper stored exercise profile.    ADVANTAGE -   Filters noise from foreign sensor/transmitter units. Provides accurate heart rate display even when transient errors in heartrate signal. Provides accurate measurements in presence of other monitors. Automatically changes frequency of heartrate signal transmission on reception errors.    (US5400794-A)      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. 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 minimised and the data displayed is very accurate.    USE -   Monitor for measuring and displaying a biomedical response such as heartbeat rate, including a transmitting unit and a receiving unit.    (JP8510926-W)      The monitor comprises a transmitter (54) for producing an encoded digital signal representing a biomedical response. The transmitter includes a wireless transmitter which transmits to a receiver (46). A display (52) monitor displays the response. A detection apparatus detects errors in the received encoded digital signal.    A correction apparatus automatically changes the transmitter and the receiver to provide for an accurate wireless transmission between the transmitter and the receiver. The correction apparatus includes a frequency changing circuit which changes the frequency over which the encoded digital signal is radio transmitted. An identification circuit (48) in the receiver checks that the received signal is in fact from the transmitter.    USE/ADVANTAGE -   Monitoring and displaying biomedical function e.g heartbeat or ECG during exercise or fitness training, to control exercise equipment in accordance with measured heart rate. Eliminates errors due interfering sources and improves accuracy of results due to error detection and correction in pattern representing body response.
