With the resurgence of non-contact vital sign sensing due to COVID-19 pandemic, remote heart-rate monitoring has gained significant prominence. Many existing methods use cameras; however previous work shows a performance loss for darker skin tones. In this paper, we show through light transport analysis that camera modality is fundamentally biased against We propose reduce bias multi-modal fusi...

There is no gold standard diagnostic method for breathing pattern disorders (BPD) which commonly diagnosed through the exclusion of other pathologies. Optoelectronic plethysmography (OEP) a 3D motion capture technique that provides comprehensive noninvasive assessment chest wall during rest and exercise. The purpose this study was to determine if OEP can distinguish between active individuals c...

Method. In asample 48 men, using a quasi-experimental design, functioning, propensity for inhibition/excitation, subjective arousal, andgenital response (penile plethysmography recorded Biopac MP150 equi...

We evaluated the use of strain gauge plethysmography (SGP) for the assessment of orthostatic fluid shifts during head up tilt (HUT). Subjects wore a parachute harness fixed to the tilt table to avoid muscle tension in the lower limbs during HUT. 22 Healthy subjects (9 women) were tilted for 5 minutes. Calf volume changes as measured by SGP, surface EMG, heart rate and blood pressure were measur...
