Abstract: A method includes determining, using a processing device, a set of observations from coolant data, the coolant data being received from one or more sensors in an environment associated with a coolant. The method further includes determining, using a machine learning model and the set of observations, a contamination level of the coolant. The method also includes initiating an operation, using the processing device, responsive to determining the coolant contamination level.

Abstract: A tilt sensor includes a one-way rotational drive configured to translate rotational motion of an input shaft in a first rotational direction about a first axis of the input shaft and in a second rotational direction about the first axis into rotational movement in a first rotational direction about a second axis of an output shaft. The tilt sensor further includes a pendulum coupled to the input shaft. The pendulum is configured to rotate the input shaft in the first rotational direction or the second rotational direction responsive to a tilt motion of the tilt sensor. The tilt sensor further includes a motion meter coupled to the output shaft. The motion meter is configured to display a measure of total tilt motion of the tilt sensor.
