<p>PROBLEM TO BE SOLVED: To provide an apparatus for monitoring breathing and heart rate in a convenient and low-cost fashion, and for deriving and displaying useful measurements of cardiorespiratory performance.SOLUTION: A motion, breathing, and heart rate signals are obtained by non-contact method typically using a high frequency sensor. The heart rate is measured by using either spectral or time-domain processing, and the respiratory rate is calculated using spectral analysis. Processing to derive the heart rate, respiratory sinus arrhythmia, or a ventilatory threshold parameter using the present system is described. The sensor, processor, and display can be incorporated in a single device which can be worn or held close to the body while exercising (e.g., in a wristwatch or mobile phone configuration), or alternately placed in a fixed piece of exercise equipment at some distance form the body (e.g., in a treadmill dash panel), and may also be integrated with other sensors, such as position locators.</p> |
