| 摘要 |
An apparatus, system, and method is disclosed for monitoring motion, breathing, heart rate and for deriving and displaying measurements of cardiorespiratory performance from said signals. The signals are obtained through a processing applied to a raw signal obtained in a non-contact fashion, typically using a radio-frequency sensor. Processing into separate cardiac and respiratory components is described. The heart rate can be determined by using spectral or time-domain processing. The respiratory rate can be calculated using spectral analysis. Processing to derive the heart rate, respiratory sinus arrhythmia, or a ventilatory threshold parameter using the system is described. The sensor, processing, and display can be incorporated in a single device which can be worn or held close to the body while exercising or alternately placed in a fixed piece of exercise equipment at some distance form the body, and may be integrated with other sensors, such as position locators. |
