Abstract: A system for collecting a fluid sample from a machine having a fluid module is provided. The system includes a docking station disposed on the machine. The system also includes a pump selectively disposed in fluid communication with the fluid module of the machine. The pump is configured to draw a fluid from the fluid module. The system further includes an Unmanned Aerial Vehicle (UAV). The UAV is configured to detachably dock onto the docking station. The UAV is also configured to collect the fluid sample from the pump.

Abstract: A method for estimating a remaining useful life of an air filter. The method includes determining, at a controller of a machine, a delta pressure of the air filter in the machine based on an input from a plurality of sensors. The method includes determining a percent plugged of the filter based upon a non-linear relationship between the delta pressure and the percent plugged of the air filter. The method includes estimating the remaining useful life of the filter based upon the percent plugged.

Abstract: A fluid degradation monitoring system may detect a replacement of a fluid of a machine. The fluid degradation monitoring system may determine, after detecting the replacement of the fluid, a first degradation estimate of the fluid using a first technique based on characteristics relating to an operation of the machine. The fluid degradation monitoring system may detect a transition in a value of a dielectric constant of the fluid from a first phase to a second phase. The fluid degradation monitoring system may determine, after detecting the transition in the value of the dielectric constant, a second degradation estimate of the fluid using a second technique based on characteristics relating to the fluid.
