Abstract: A method of operating a usage-based maintenance system for a vehicle among a plurality of vehicles includes determining, for a time period, an exposure parameter of the vehicle. The exposure parameter indicates an amount of exposure to an environment during the time period. The method also includes scoring the exposure parameter according to an exposure model to produce an exposure score. Moreover, the method includes determining a maintenance discount according to the exposure score.

Abstract: A computer-implemented method for determining a scheduled maintenance session for a proportional actuator includes transmitting a command signal to a controller of the proportional actuator and generating, using the controller, a drive signal for controlling the proportional actuator using the command signal. The position of a component actuator of the proportional actuator is changed, on the basis of the drive signal, and the position of the component actuator is measured, using a sensor, and a position feedback signal is generated on the basis of the measurement. A condition indicator is estimated, with a processor, using only one of the command signal, the drive signal, or the position feedback signal. A health indicator is estimated, with the processor, using the condition indicator, and a scheduled maintenance session of the proportional actuator is determined, with the processor, using the health indicator.

Abstract: A computer-implemented system for detecting shifts in data is provided. The system is configured to: calculate, based on the value of a plurality of user-selectable baseline configuration parameters, baseline values for a series of data items in a data structure, wherein the baseline values include an average value and a standard deviation value; calculate, based on the value of a plurality of user-selectable weighted threshold parameters, a weighted threshold level for the series of data items; detect, based on the value of a plurality of user-selectable shift detection parameters, a shift in the series of data items, wherein the shift comprises an abrupt shift, a rapid drift, or a gradual drift; convert, based on the value of a plurality of user-selectable normalization parameters, the value of each data item in the series of data items to a normalized value; and determine whether the normalized values indicate a data shift.

Abstract: A system and method for identifying engine wear based on engine oil debris is provided. The provided system and method utilize metallic debris data provided in summary reports. For each object of metallic debris, a zap count, an initial (pre-zap) impedance and an impedance change (post zap) are processed with configurable reference variables. Alerts (suggesting potential engine wear) are generated responsive to the impedance values of the objects of metallic debris and the reference variables.
