Abstract: A space station includes a housing that defines an interior space. An inner chamber is located in the interior space and defines an inner cavity that is sealable from the remainder of the interior space. At least one bulkhead is arranged in the interior space to partition the interior space into at least two compartments that are hermetically sealable from one another. One compartment can be accessed from another compartment via the inner cavity of the inner chamber. The inner cavity is sealable against each compartment. Openings in an outer surface of the housing enable crew members to leave a damaged compartment through the opening. Thus, alternative routes exist to leave a damaged compartment, i.e., either through the inner cavity or through the opening in the outer surface of the housing. When one compartment is damaged, the adjacent compartments are still operative because they are sealed from the damaged compartment.

Abstract: A system, method, and air purification device. Air is taken in from an environment into the air purification system. The air is filtered with a primary filter. The filtered air is treated with vacuum ultraviolet radiation in a primary reaction chamber to generate irradiated air. The irradiated air is treated with ultraviolet-C radiation in a secondary reaction chamber to remove ozone and neutralize contaminants to generate purified air. The purified air is emitted back into the environment from the air purification system.

Abstract: Quorum-based access control management may be implemented. Quorum controls may be created for determining whether to perform or deny access control operations to perform privileged tasks. When an access control operation is received, approval of the operation may be requested from members for the quorum control. If a policy for the quorum control is satisfied by approval responses, then approval to perform the access control operation may be provided.

Abstract: In one embodiment, an audio system can generate parametrically formulated noise signals. According to an embodiment, an audio system can both determine the hearing ability of an individual and increase the hearing ability of the individual by using parametrically formulated noise. According to an embodiment, an audio system can generate parametrically formulated noise having a power spectrum amplitude that is a function of an individual's hearing threshold across a range of frequencies as measured using parametrically formulated noise test signals.
