Classification: CPC F  G | IPC F  G

Claim 11:
12. A network comprising:
a first monitored system comprising:
a first internal combustion engine,
a first sensor, and
a first engine control unit; and

at least one server external to the first monitored system, 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 the first engine control unit, the first signal associated with a first occurrence of a first internal combustion engine event of the first monitored system, a second occurrence of the first internal combustion engine event, and first measurement data of the first sensor;
determine a first measurement from the first measurement data based on the first occurrence of the first internal combustion engine event;
determine a second measurement from the first measurement data based on the second occurrence of the first internal combustion engine event;
determine a reference measurement from the first measurement data;
determine a first reference deviation between the first measurement and the reference measurement;
determine a second reference deviation between the second measurement and the reference measurement;
compare the first reference deviation to a stored first reference threshold;
compare the second reference deviation to a stored second reference threshold;
after determining that the first reference deviation is less than the first reference threshold and the second reference deviation is less than the second reference threshold, determine a first measurement deviation between the first measurement and the second measurement;
compare the first measurement deviation to a stored measurement threshold; and
after determining that the first measurement deviation satisfies the measurement threshold, determine a first exhibited useful life of the first sensor based on the first measurement deviation and at least one of the first measurement or the second measurement.
