An oxygen supply system includes a container housing having a container door, a latch controller coupled to a latch of the container door and configured to control the latch to releasably open the container door, a microcontroller coupled to the latch controller and configured to output a first latch deployment signal to the latch controller to cause the latch controller to open the latch, a pressure sensor coupled to the latch controller and configured to output a second latch deployment signal to the latch controller to cause the latch controller to open the latch, and an energy storage coupled to the microcontroller and the pressure sensor and configured to supply the microcontroller and the pressure sensor with electrical energy. The microcontroller includes built-in test equipment (BITE) configured to monitor and test the operability of one or more of the microcontroller, the latch controller, the pressure sensor and the energy storage.

A packaged filtration mask comprising a filtration mask packaged in a container in a vacuum or a partial vacuum, wherein the packaged filtration mask comprises an indicator configured to indicate the presence of a vacuum or a partial vacuum in the container, or configured to indicate the lack of a vacuum or a partial vacuum in the container.

A process manufactures a padding device (10a; 10b; 10c; 10d; 10e), for a carrying belt system (100) for a respirator (1000), having a closed pad core shell (20) and a pad core (30) configured in the pad core shell. The process includes injection molding a hollow profiled section, inserting of a pad core material into the hollow profiled section for forming the pad core in the hollow profiled section, and closing the hollow profiled section (21) for creating the closed pad core shell (20). The padding device (10a; 10b; 10c; 10d; 10e) has a closed pad core shell (20) and a pad core (30) arranged in the pad core shell. The pad core shell is seamless as an injection-molded component in at least some sections. A carrying belt system as well as a respirator with the carrying belt system are provided with the belt system having the padding device.
