An extravehicular mobility unit (EMU) includes a resonant coil on a surface of the EMU to be coupled to a second resonant coil affixed to a structure via a resonant magnetic field. The EMU also includes a receiver in the EMU coupled to the resonant coil to provide a direct current (DC) voltage based on the resonant magnetic field. A battery in the EMU is charged based on the DC voltage.

A carbon dioxide sensor has a conduit connecting to a source of breathing air and delivering a sample of breathing air into a test chamber. A radiation source applies radiation across the chamber. A sensor detects modification in the radiation as it passes through the air sample in the test chamber and communicates with electronics to identify a percentage of carbon dioxide in the sample. A rigid cover surrounds the radiation source, the test chamber, and the sensor. A spacesuit is also disclosed.

According to one aspect of the present disclosure, a battery circuit is disclosed that includes a plurality of battery cells. The plurality of battery cells includes at least one connected battery cell and at least one disconnected battery cell. A first switch is configured to disconnect a particular one of the at least one connected battery cells, and a second switch is configured to connect a particular one of the at least one disconnected battery cells. A controller is configured to control the first and second switches based on a detected condition in the particular connected battery cell.

Intelligent battery self repair

A system includes a first control system configured to operate at a first clock speed, a second control system configured to provide an output to the first control system and configured to operate at a second clock speed different from the first clock speed, and a synchronization module operatively connecting the first control module to the second control module and configured to synchronize the first control system and the second control system such that the output of the second control system is timed to synchronize with the first clock speed.
