Abstract: Systems and methods for monitoring an alternator are described. A system for monitoring an alternator comprises: a current sensor configured to measure a current signal from the alternator over time; and a controller configured to: extract parameters from the current signal; and analyze the parameters and thereby identify a potential fault in the alternator.

Abstract: Systems and methods for monitoring a pneumatically actuated door are described. A monitoring system for a pneumatically operated door, comprises: a dew point sensor configured to monitor a moisture level of an interior of a cylinder of a pneumatic actuator of the pneumatically operated door; and a controller coupled to the dew point sensor and configured to compare the moisture level of the interior of the cylinder of the pneumatic actuator of the pneumatically operated door with a threshold and to generate an alert if the moisture level exceeds the threshold.
