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.

Abstract: A wireless power transmitter for transmitting power by wireless to a terminal includes a power conversion unit and a power transmission control unit. The power conversion unit forms a wireless power signal for wireless power transfer using power supplied from a power supply unit. The power transmission control unit regulates a characteristic of the supplied power, based on orientation information of the terminal. A terminal includes a power receiving unit and a control unit. The power receiving unit receives a wireless power signal formed by a wireless power transmitter. The control unit detects whether or not an orientation of the terminal is changed while the wireless power signal is received, and transmits a control message for power regulation to the wireless power transmitter when the change in the orientation of the terminal is detected.
