Abstract: A diagnostic system for a closed fluid system is provided. The closed fluid system includes a first fluid subsystem and a second fluid subsystem connected using a valve or valve/actuator. The diagnostic system includes a first sensor disposed in the first fluid subsystem, a second sensor disposed in the second fluid subsystem and a computer. The computer receives first time-ordered fluid level measurements and second time-ordered fluid level measurements from respectively the first sensor and the second sensor and performs a comparison of first fluid level of the first fluid subsystem and second fluid level of the second fluid subsystem. The computer produces a notification indicating a predicted transfer of hydraulic fluid when the first time-ordered fluid level measurements and the second time-ordered fluid level measurements have at least a threshold divergence and outputs the notification for display to a user.

Abstract: Methods and maintenance systems for use in analyzing data related to maintenance of at least one vehicle are disclosed. One example method includes receiving at least one fault message, receiving a maintenance event log for a vehicle. The maintenance event log including at least one maintenance event associated with the at least one fault message. The example method further includes automatically identifying a corrective action within a most recent maintenance event of the at least one maintenance event and storing a diagnostic entry including the at least one fault message and the identified corrective action, such that the diagnostic entry is retrievable from the computing device to evaluate a subsequent like fault message.

Abstract: A computer implemented apparatus, and computer usable program code for automatically obtaining vehicle data. In one advantageous embodiment a computer implemented method monitors a vehicle for events over a wireless interface. In response to receiving an event sent over the wireless interface by the vehicle, a determination is made whether vehicle data is needed for the event based on a policy. A request for the vehicle data is sent over the wireless interface to the vehicle in response to a determination that vehicle data is needed. The vehicle data is stored in response to receiving the vehicle data over the wireless interface from the vehicle. The vehicle data stored after receiving the vehicle data from the vehicle is analyzed to form an analysis. A set of fault conditions may be identified using the analysis.
