  • Patent number: 12263362
    Abstract: A mask apparatus includes a mask body, a fan module, a seal that defines a breathing space, a pressure sensor coupled to the mask body and configured to sense an air pressure in the breathing space, and a controller coupled to the mask body and configured to control a rotation speed of the fan module based on the air pressure. The controller is configured to determine a breathing cycle based on a maximum pressure value and a minimum pressure value among air pressure values sensed by the pressure sensor, determine a time difference between a maximum time point and a minimum time point, determine an expected time point of inhalation in a subsequent breathing cycle based on the breathing cycle and the time difference, and increase the rotation speed of the fan module based on a current time corresponding to the expected time point of inhalation.

  • Patent number: 12161892
    Abstract: A mask apparatus includes a mask body having a fan module, a seal defining a breathing space, a pressure sensor sensing air pressure in the breathing space, a mask body cover coupled to the mask body, and a controller that controls a rotation speed of the fan module based on pressure values. The controller is configured to determine breathing information including a maximum pressure value and time point, and a minimum pressure value and time point, determine a breathing state of a user based on the breathing information, determine whether the breathing state is a steady state, determine a tidal volume of the user based on the breathing information, and control the rotation speed of the fan module based on the tidal volume.

  • Patent number: 12089668
    Abstract: Provided is a mask apparatus. The mask apparatus includes a mask body in which a microphone and a speaker are installed, a face guard coupled to a rear surface of the rear body so as to be in close contact with a user's face and having a breathing space therein, a pressure sensor installed in the mask body to measure a pressure of the breathing space, and a controller configured to compare a current pressure value measured by the pressure sensor to a reference pressure value and control a voice output of the speaker based on a difference between the current pressure value and the reference pressure value.

  • Publication number: 20230015788
    Abstract: Provided is a method for controlling a mask apparatus. The method for controlling the mask apparatus includes measuring a current pressure value with respect to a mask by using a pressure sensor, comparing each of a preset atmospheric pressure maximum estimation and a preset and a preset atmospheric pressure minimum estimation to the current pressure value; updating the atmospheric pressure maximum estimation and the atmospheric pressure minimum estimation according to the comparison result, and controlling a voice output of a speaker based on a difference between the updated atmospheric pressure maximum estimation and the updated atmospheric pressure minimum estimation.
