All fluid, now in the drain pan, can be drained and collected in a disposable container such as a plastic pouch, which can be recycled. The filter element can be removed from the housing via the removed cover.

Abstract: Described is a system for human-machine teaching for vehicle operation. The system determines currently enabled status reporting modes on a vehicle interface of a vehicle. The currently enabled status reporting modes are compared to a set of preferred status reporting modes of previous users. Based on the comparison, a status reporting mode is selected. A current operational status of the vehicle is reported to a current user, via the vehicle interface, using the selected status reporting mode. The system then determines preferred solutions of previous users to address the current operational status of the vehicle. Suggestions to address the current operational status of the vehicle based on the preferred solutions are reported to the user via the vehicle interface. A vehicle action corresponding to a solution selected by the current user is implemented via a vehicle component.

Abstract: Systems, methods, and computer program products for monitoring a wind turbine (10). The system receives a signal (426) indicative of a pitch force being applied to a blade (20) of a wind turbine (10). The signal (426) is sampled to generate a discrete time-domain signal (426) including a plurality of pitch force samples. Samples are selected for analysis using a sampling window (326) that excludes samples obtained under operating conditions determined to be detrimental to obtaining good data. The selected samples are processed to generate a spectral density (150) of the signal (426), and the frequency content of the spectral density (150) analysed to determine the condition of one or more components of the wind turbine (10). If the analysis indicates that a component of the wind turbine (10) needs attention, the system generates an alarm.
