Abstract: The present disclosure relates to an optical sensor system including a track system, an optical sensor operably, coupled to the track system, comprising at least one emitter and at least one detector, and a controller operably coupled to the optical sensor. In this regard, the optical sensor is configured to perform measurements comprising at least one physiological parameter. Furthermore, the controller is configured to actuate the optical sensor to move the at least one emitter and/or the at least one detector along the track system to at least one preferred location based on the at least one measured physiological parameter and/or at least one user parameter.

Abstract: The present invention provides a method (100) for determining at least one parameter related to the microcirculation function of a person, said method comprising the steps of a) determining (101) an arrival time (AT) of a pulse wave, wherein the AT is the time between the onset of an activity of the heart producing said pulse wave and the arrival of said pulse wave in a part of the body of said person; b) varying (102) an applied pressure (P) on said part of the body over time and determining said AT as a function of applied pressure and time; and c) assessing (103) said at least one parameter related to the microcirculation function based on said determination of AT and said AT as a function of applied pressure and time in steps a) and b). The present invention further provides a system (1) for determining at least one parameter.

Abstract: A method for providing personalized health assessment of a subject includes: receiving a raw electrocardiography (ECG) signal of a subject from an ECG device and a raw blood pressure (BP) signal of the subject from a BP waveform detector; calculating a beat-to-beat ECG signal from the raw ECG signal; calculating a beat-to-beat BP signal from the raw BP signal; calculating a beat-to-beat pulse arrival time (PAT) signal that is measured as a time delay between the beat-to-beat ECG signal and the beat-to-beat BP signal; calculating an interpolated beat-to-beat PAT signal and an interpolated beat-to-beat BP signal by interpolating the beat-to-beat PAT signal and the beat-to-beat BP signal, respectively; assessing a subject-specific relationship between the interpolated beat-to-beat PAT signal and the interpolated beat-to-beat BP signal; and estimating a real-time blood pressure of the subject based on the subject-specific relationship.
