Abstract
A facemask assembly for a self-contained breathing apparatus includes a facemask configured to be worn by a user, an electronic device connected with the facemask, a microcontroller configured to send signals to the electronic device, an accelerometer coupled with the microcontroller and configured to sense motion of the facemask; and a battery configured to supply power to the electronic device. When motion is detected by the accelerometer, a signal is transmitted to the microcontroller and the microcontroller interprets the electrical signal to selectively adjust the power level supplied to the electronic device.
