Methods for Blood Pressure Estimation from Short Duration of Photoplethysmogram (PPG) Signals via Transfer Learning
Invention Summary:
Hypertension or high blood pressure affects a large percentage of the global adult population. Frequent self-monitoring of blood pressure (BP) is important for long-term adherence and compliance to clinical advice. However, given the intrinsic inconvenience of conventional cuff- or tonometry-based blood pressure...

PulseLab: An Integrated and Expandable Toolbox for Pulse Wave Velocity-base Blood Pressure Estimation
Invention Summary:
Cuff-less blood pressure (BP) estimation methods have been long pursued as substitutions for the conventional BP measurement methods to facilitate continuous and automatic monitoring of BP. The PWV (pulse wave velocity)-BP models, describing the relationship between the PWV and the BP, have been derived and used in recent...
