Déplacements Thoraciques Submillimétriques Mesurant Pouls et Respiration
Extraction des micro-vibrations de 0,1 à 0,5 mm de la paroi thoracique dues aux battements cardiaques, distinctes du cycle respiratoire de 5 à 12 mm.
Variational Mode Decomposition (VMD)
VMD mathematically separates the narrow-band respiratory harmonics from high-frequency cardiac beat signatures without phase distortion.
- Measures respiration rate within ±1 breath per minute.
- Heart rate tracking accuracy within ±2 beats per minute.
- Operates through winter jackets, heavy blankets, and seat cushions.
- Immunity to in-cabin optical shadows, fog, and total darkness.
