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: Methods, devices, and systems automatically monitor and mitigate contamination caused by particulate in air that enters a server enclosure during operation. A particulate sensor detects an amount of particulate in the air and, when the amount exceeds a predetermined particulate limit value, a filter is automatically moved into an airflow path between an environment outside of the server enclosure and an environment inside the server enclosure. In this position, air entering the server enclosure is caused to pass through the filter when the predetermined particulate limit value is exceeded. In addition to active filtering, detected contamination across several units of scale is mapped to generate an air quality trend. The air quality trend provides information to technical personnel about contamination events and can aid in addressing the source of contamination before damage occurs to a server.

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.
