  • Publication number: 20240001059
    Abstract: A humidifier (12) of a heated pass-over type for use in a respiratory therapy device (54) comprises a heater plate (70), a water reservoir (62), one or more sensors (86), and a controller (88). The water reservoir (62) houses a volume of water (66) and includes one surface for contacting the heater plate (70). The sensors (86) generate output signals conveying information about an operating status of the humidifier (54) and ambient conditions. The controller (88) controls an evaporation rate of the volume of water housed in the water reservoir (62) with a power control according to a power control algorithm for humidifying the flow of breathable gas (60) received at the breathable gas inlet (72) of the water reservoir (62) into a flow of humidified breathable gas (78) at the humidified breathable gas outlet (74) of the water reservoir (62).

  • Patent number: 11399926
    Abstract: The invention relates to a mouthpiece for performing a treatment of teeth such as teeth whitening. Accordingly, the mouthpiece may be arranged for cosmetic treatment. The treatment is based on illumination of the teeth of light with a suitable wavelength. The mouthpiece is designed so that light from light sources, e.g. LED's, is sufficiently homogenized so that the light irradiance at the teeth is sufficiently uniform to achieve good treatment results. Furthermore, the mouthpiece is designed so that the irradiance at the teeth is sufficiently high to achieve efficient treatment and so that heating of the teeth is minimized to an acceptable heating.
