Classification: CPC F  G | IPC F  G

Claim 17:
18. At least one server, the at least one server comprising at least one processor coupled to at least one memory storing instructions that, when executed by the at least one processor, cause the at least one server to:
receive a first signal from a first monitored system that comprises an internal combustion engine and a first sensor, the first signal associated with a first occurrence of an internal combustion engine event of the first monitored system, a second occurrence of the internal combustion engine event of the first monitored system, a third occurrence of the internal combustion engine event of the first monitored system, and first measurement data of the first sensor;
determine a first measurement from the first measurement data based on the first occurrence of the internal combustion engine event;
determine a second measurement from the first measurement data based on the second occurrence of the internal combustion engine event;
determine a third measurement from the first measurement data based on the third occurrence of the internal combustion engine event;
determine a rate of change between the first measurement, the second measurement, and the third measurement;
compare the rate of change to a stored rate threshold;
determine a threshold deviation between a first operation measurement associated with the first occurrence of the internal combustion engine event and a second operation measurement associated with the second occurrence of the internal combustion engine event after receiving the first signal;
determine a measurement deviation between the first measurement and the second measurement;
compare the measurement deviation to the threshold deviation; and
after determining that the measurement deviation satisfies the threshold deviation, determine a first exhibited useful life of the first sensor based on the measurement deviation and at least one of the first measurement or the second measurement; and
after determining that the rate of change satisfies the rate threshold, determine a second exhibited useful life of the first sensor based on the rate of change and at least one of the first measurement, the second measurement, or the third measurement.
