Embodiment Construction

[0027] figure 1 is a schematic representation of various environments in which the system may be used in the assessment of sports and activities. First, the device can be used in ambulatory applications (where the person is free to move because they are wearing a cardiopulmonary monitor). figure 1 (A) shows an embodiment of the system as an upper arm cuff. figure 1 (B) shows the system as a clip-on device attachable to a shirt pocket. figure 1 (C) shows an example of a device worn as a pendant around the neck, figure 1 (D) represents a cardiorespiratory monitor in a treadmill fitness system, figure 1 (E) An example of a cardiorespiratory monitor embedded in an exercise bike is given, and figure 1 (F) shows the device as a watch-like device while swimming. The device may also be configured for use with other known exercise machines.

[0028] figure 2 A schematic representation of an exemplary sensor element is provided. The sensor element uses radio frequency de...

Abstract

An apparatus, system, and method is disclosed for monitoring the motion, breathing, heart rate of humans in a convenient and low-cost fashion, and for deriving and displaying useful measurements of cardiorespiratory perfonnance from the measured signals. The motion, breathing, and heart rate 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 either 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 (e.g., in a wristwatch or mobile phone configuration), or alternatelyplaced 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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 60 / 863,862, filed November 1, 2006, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to monitoring the movement, respiration, and heart rate of a living organism, such as a person, in a convenient and low-cost manner useful, for example, in the assessment of cardiorespiratory fitness and activity markers, and more particularly, to a method for Devices, systems and methods for acquiring, processing and displaying corresponding information. In this application, reference is made to a system that measures motion, respiration, and heart rate as a cardiorespiratory monitoring device or system. Background technique [0004] Monitoring of heart rate and respiration facilitates assessment of cardiorespiratory system performance. For example, the measurement of heart rate is useful when assessin...
