1. A method for determining a person'"'"'s heart pulse rate, comprising:

  • radiating first and second wavelengths of light towards a tissue;

    measuring and storing a first and second set of parameter values from the signals reflected back from said first and second wavelengths respectively, wherein said first set of parameter values represents a first signal corresponding to a combination of the heart pulse rate and extraneous noise and said second set of parameter values represents a second signal mainly comprising extraneous noise;

    deducting the second set of parameter values from the first set of parameter values, thereby to obtain the heart pulse rate.
