In this paper, we propose the use of a Doppler radar system with continuous wavelet transform (CWT) analysis for in-home gait characterization. A methodology based on an accurate 3D motion-capture camera system (Vicon) has been developed in order to validate the suitable mother wavelet. The ...
Objective: We taught parents to use at home a hand-held Doppler device and aneroid sphygmomanometer for SBPmeasurement (HDBPM). Methods: Retrospective study including all children referred to evaluate hypertension over a 6-year period. Each child underwent HDBPM measurements performed by parents ...
Time–frequency analysis (TFA) is a widely applied method in continuous wave radar technology, including micro-Doppler analysis, target recognition, driving behaviour detection, etc20,21,22,23,24. Short-time Fourier transform (STFT) is a linear TFA method that intuitively illustrates the variation ...

The key finding is that static, regular action, and sudden falls make an impact on the RSS and Doppler frequency values differently. Such features help us to detect the status of the elderly. A wavelet transform...

For spectator orientation stereo headphones or speakers help detect the difference in position, assuming your volume and location settings put the helicopter in audible range. The same is true for the Distance Attenuation settings, which enable you to control the doppler effect. ...
Transfer/in-flight alignment technique using a Doppler velocity sensor. An aircraft navigation system (10 and/or 20), a Doppler velocity sensor (50) and an alignment filter (45) are used to align the
