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.

Abstract: The present disclosure provides a charging system. The charging system includes a first device. The first device includes a first power interface. The first device further includes a first communication module. The first communication module includes at least one first transceiver. The first device further includes a second communication module. The second communication module includes at least one second transceiver. The first device further includes an intrinsic barrier disposed between and physically separating the first communication module from the second communication module. The first communication module and the second communication module are configured to wirelessly exchange data signals therebetween. The charging system further includes a second device including a second power interface. The first power interface and the second power interface are configured to be electrically connected to each other to transfer electrical power between the first and second devices.
