SATHeart USP is a technique called Active Breathing (TM) that interactively guides the user's breathing towards the aim of her/his choice: calming, focusing, energizing and sleeping. It is thus a biofeedback based on blood pressure pulse wave analysis method that gently drives the user's breathing patterns. Target markets are stress management, sport performance, breathing disorder and sleep management.SATHeart provides solutions for the wellness, fitness, sport and medical markets with dedicated features using a hand held or arm located digital biosensing device for the best accuracy matching medical grade systems.Higher level metrics includes: Breathing Score, Energy Balance and Sleep Scores. These metrics are included in our coming App and can also be included in our Embedded Biosignal Toolboxes which includes: heart rate, heart rate variability indices, breathing signals and rates, peripheral oxygen level, skin temperature and vascular stiffness indices.Do not hesitate to contact us: patrick.celka@satheart.com.

Development of algorithms for Human Vital Signs analysis based on motion sensors and photoplethysmography. Most of algorithms are dedicated to embedded processing and based on white box (physiological) or grey box (physiological + machine learning) models. Among the algorithms, I worked out the following parameters:1) Human activity and public transport classification2) Energy expenditure estimation3) Heart Inter-beat intervals estimation4) Spontaneous and paced breathing rate5) Cuff-less blood pressure estimation6) Blood pulse wave analysis and modelling7) Cardiovascular modeling

We develop algorithms for vital sign monitoring and analytics for wearable and non-wearable devices. Our focus is on the analysis of the blood pulse wave as measured from the photoplethysmography at different places of the body along with other physiological signals such as electrocardiogram, electroencephalograms, respiration or blood pressure and flow. We also develop algorithms for motion quantification and classification. Our interests are on wellness and sport market as well as clinical applications such as heart arrhythmia detection, breathing pattern analysis, sleep disorders and sleep disordered breathing.We also have some interest in using eastern medicine concepts to our algorithms and methodologies, especially those connected to the knowledge of pulse reading.
