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: A method of communicating using a breathing apparatus includes receiving an audio signal from a sound acquisition unit. The method further includes determining a state of the breathing apparatus based on the received audio signal. The state is at least one of a first state and a second state. The method further includes applying a first filter on the audio signal if the determined state is the first state. The first filter has a first frequency response. The method further includes applying a second filter on the audio signal if the determined state is the second state. The second filter has a second frequency response different from the first frequency response of the first filter. The method further includes generating an output signal based on the application of the first filter or the second filter. The method further includes receiving the output signal at an output device.

Abstract: A method implemented in a first wireless unit of a plurality of wireless units of a first group. The method includes determining whether a second wireless unit of the first group is configured as the master of the first group. If the second wireless unit is configured as the master of the first group, the first wireless unit is configured as a slave and the first wireless unit is joined to the first group to communicate with the other wireless units. In addition, if the second wireless unit is not configured as the master of the first group, the first wireless unit is configured as the master of the first group and one of the first group is formed and the first group joined to communicate with the other wireless units. An apparatus is also provided.

Abstract: A thermal imaging system for use with a respirator mask comprising an in-mask display unit, and methods of configuring and operating such a system. The system uses a thermal imaging camera to capture a thermal image. The system is configured with the capability to shift from a default view in which an in-mask micro-display of the in-mask display unit shows a primary subimage of the captured thermal image but does not show a secondary subimage of the captured thermal image, to an auxiliary view in which the secondary subimage is now shown in place of at least a portion of the primary subimage.
