  • Systems and methods for determining exhibited useful life of sensors in monitored systems
    Patent number: 11959433
    Abstract: At least one server comprising at least one processor coupled to at least one memory storing instructions. The server can receive a first signal from a first monitored system comprising an internal combustion engine and a first sensor, the first signal associated with a first occurrence of an internal combustion engine event, a second occurrence of the internal combustion engine event, and first measurement data of the first sensor. The server can determine a first measurement from the first measurement data. The server can determine a second measurement from the first measurement data. The server can determine a measurement deviation between the first measurement and the second measurement. The server can compare the measurement deviation to a stored measurement threshold. The server can 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.
