  • Publication number: 20200141913
    Abstract: A device (1) comprising a cavity (5) defining an internal volume, an air quality sensor (9) being adapted to measure a concentration of at least one air compound present in the internal volume, the cavity (5) can be alternatively in: an open state in which air can enter into the cavity (5) from the outside of the cavity (5), and a closed state in which no air can circulate between the outside and the inside of the cavity (5), the air quality sensor (9) being adapted to be calibrated when the cavity (5) is in the closed state and once the internal volume no longer comprises the air compound or comprises a concentration of the air compound that is below a predefined threshold.

  • Patent number: 10409226
    Abstract: A wearable device with an air quality sensor, the wearable device, comprising a housing enclosing an electronic board, a display arrangement, a battery, the housing lodging a cavity with an internal area, the cavity containing an air quality sensor in the internal area, the cavity being delimited by a cavity wall and by a membrane, the membrane having an inner wall oriented toward the cavity internal area and an outer wall opposed to the inner wall, the internal area of the cavity being in fluid communication with the ambient air through the membrane, the membrane being permeable to air and substantially not permeable to water.

  • Publication number: 20180014816
    Abstract: A method for determining a fertility period for a female human individual (FU), carried out in a device comprising a controller, a non-invasive heart sensor placed in contact or opposite to a portion of the skin of the individual, during the sleep of the individual, the heart sensor being configured to sense heart pulses of the individual and the controller being configured to determine the heart rate, the method comprising the following steps: /a/ collecting, at the sensor, heart pulses signals of the individual; /b/ extracting therefrom, at the controller, current heart rate during a night; /c/ calculating a minimal sleep heart rate denoted MSHR(i), over the night; /d/ comparing MSHR(i) with values of MSHR(k) recorded previously, and/or comparing MSHR(i) with a long term average of the minimal sleep heart rate values denoted LTHR; /e/ deducing therefrom a current ovulation probability index, according to a predefined criteria; /f/ if the ovulation probability index is higher than a predefined threshold deno
