Abstract: The present disclosure relates to a method and a device for transmitting data in a wireless power transmission system. The method for transmitting data by a wireless power transmitter in a wireless power transmission system may comprise the steps of: receiving from a wireless power receiver, within a first control error interval, a first control error packet containing a control error value with respect to power transmitted from the wireless power transmitter; determining the size of a first data packet on the basis of the length of the first control error interval; and transmitting the first data packet to the wireless power receiver.

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.
