Abstract
Method for automatic stop-start control of a breathing apparatus. Automatic starting and stopping of the device based upon the determination of a user wearing the mask by way of proximity sensors determining that a user is physically in contact with the mask in order to start the device and stopping the device when the proximity sensors determine the user is not in physical contact with the mask.
