ABSTRACT:
An alarm system and method for use with a breathing apparatus that provides a source of breathable air to a user/diver. A tactile signal is generated in response to a signal representing at least one parameter corresponding to the breathing apparatus status, and the tactile signal can be both felt and heard by the user. The tactile signal may be generated in combination with a visual and/or an additional audible alarm. The tactile signal may be a vibration. The alarm may be worn on the face, either on the mask or on the mouthpiece. The vibrator serves two functions, one as a tactile alarm that the diver can feel during operation, and a second as an auditory alarm through bone-conduction of sound. The tactile alarm indicates to the user/diver that his particular unit is the one transmitting an alarm signal, and cannot be mistaken for any other device. The tactile signal may be generated to have one or more signal characteristics that are modulated to convey additional information about the parameter or parameters being monitored.
