Publication number: 20170172435Abstract: The invention relates to a physiological property determination apparatus (1) for determining a physiological property like a pulse rate of a person. The apparatus may be configured to be worn on the wrist like a watch. A controller (8) separately controls at least two light sources (3, 4, 5) for emitting at least two light beams having different wavelengths into tissue of the person and a light detector (6) having a two-dimensional detection surface (12) detects light, which has travelled through the tissue, wavelength-dependently and generates a wavelength-dependent two-dimensional image based on the detected light. Based on the generated wavelength-dependent two-dimensional image the physiological property is determined. The separate control of the light sources allows for an independent optimization of the illumination and detection processes for each wavelength, which in turn can lead to an improved determination of the physiological property based on the wavelength-dependent two-dimensional image.Type: ApplicationFiled: February 13, 2015Publication date: June 22, 2017Inventor: Cristian Nicolae Presura

Publication number: 20170172443Abstract: The method is used for filtering an initial RR series of a plurality of (RRi) samples which are respectively a function of the time intervals (?ti) that separate two successive heartbeats. In order to carry out this filtering, one must automatically detect in the initial RR series if one or more successive (RRi) samples are incorrect, and automatically correct in the RR series one or more of the (RRi) samples detected as being incorrect by replacing them with one or more reconstructed (RRc) samples so as to obtain an RR series. One must automatically control the quality of the RR series by counting, in a predefined sliding window, the number (NbPertub) of (RRc) samples of the RR series that were reconstructed, and/or, if applicable, the number (NbPertub) of (RRrc) samples of the RR series that were reconstructed and resampled.Type: ApplicationFiled: February 20, 2015Publication date: June 22, 2017Inventors: Régis Logier, Julien De Jonckheere, Mathieu Jeanne, Thomas Margez
