  • Publication number: 20240023992
    Abstract: Disclosed is a device for detecting a pressure, of the type including a detection element on which a pressure is exerted, a transducer connected to the detection element and an elastically deformable shell. The shell is made of biocompatible and sterilizable material, has two opposing walls and an insertion opening, and the detection element includes at least one elastically deformable tube, the tube includes a portion arranged in the shell, the tube is closed at one end and filled with a fluid, the other end of the tube being open, arranged outside the shell and connected to the transducer.

  • Publication number: 20230293072
    Abstract: A method to detect drowsiness of an individual. The method includes: (a) acquiring a cardiac signal; (b) processing the cardiac signal to detect time intervals between successive heartbeats; (c) extracting, from the time intervals, characteristic HRV variable(s) of the heart rate variability, each HRV variable being obtained from a plurality of the time intervals; (d) calculating at least one direction aggregate for the HRV variable(s), each being a variable calculated from the HRV variable in a sliding time window, and which characterizes a trend in the window, and/or calculating at least one shape aggregate for the HRV variable(s), each being calculated from values of the HRV variable in a sliding time window and quantifying the shape of a distribution of values of the HRV variable in the window; and (e) processing the direction aggregate(s) and/or the shape aggregate(s) using a detection algorithm enabling detection of drowsiness of the individual.

  • Patent number: 11020056
    Abstract: The method allows controlling the quality of an initial RR series made up of a plurality of (RRi) samples which are respectively a function of time intervals (?ti) which separate two successive heartbeats. During this method, one resamples the RR series so as to obtain a resampled RR series, and one automatically controls the quality of the RR series by automatically calculating at least the mathematical norm value (NORME), in a sliding window, of the resampled RR series, said mathematical norm value being given by the following formula: NORME = ? i = 1 N ? ( RR i - 1 N ? ? i = 1 N ? ( RR i ) ) 2 where N is the number of RRi samples in said window.

  • Publication number: 20170172443
    Abstract: 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.
