Abstract: A breathing apparatus designed to display at least one condition associated with the breathing apparatus to the user of the breathing apparatus. The breathing apparatus includes a breathing mask, a display assembly and a sensor assembly. The display assembly includes at least one display designed to display at least one condition of the display assembly and/or the sensor assembly. The breathing apparatus design can be designed to enable a third party to view at least one condition of the display assembly and/or the sensor assembly while a user is wearing the breathing mask. The breathing apparatus can include a sealing arrangement for forming a seal between a circuit board and/or other electronic components and a housing of the display assembly and/or the sensor assembly.

Abstract: A system and method of providing a wireless heads-up display for displaying the amount of breathing gas remaining in an associated breathing gas supply is provided. The system has a transmitter and a receiver. The transmitter has a pressure sensor and a controller for interpreting the sensed pressure into levels indicative of the amount of breathing gas remaining in the breathing gas supply. These levels are transmitted via radio frequency to the receiver. The receiver, which can be mounted in a breathing mask, includes a display for displaying the amount of breathing gas remaining in the associated breathing gas supply.

Abstract: A communication system for a mask including an externally mounted microphone and ear speaker assembly is provided. The microphone and ear speaker assembly are adapted for electrical interconnection with a radio. A lapel microphone assembly optionally including a transmission activation device, a microphone, a speaker and an amplifier may be included. An interconnection cable connecting the microphone and ear speaker assembly to a lapel microphone assembly facilitates connection and disconnection between the assemblies.

Abstract: A self-contained breathing apparatus (SCBA) based accountability system is provided. The system includes at least one communication module affixed to the SCBA. The communication module includes, for example, an electronic key port configured to accept an electronic key device having identification information, at least one sensor port for interfacing with at least one sensor system, and a controller in circuit communication with said electronic key port. The communication module reads, stores, and transmits the identification information to a command post for remote monitoring. The communication module also transmits data received through the sensor port to the command post. The sensor system that interfaces with the communication module can include a wide variety of sensors including, for example, a pressure sensor for sensing pressure from the breathing gas tank of the SCBA. Other Insensors include temperature, gas, and physiological sensors.
