Claim:
1. A reusable noninvasive physiological sensor configured to store sensor use information, the sensor comprising: a first and second emitter configured to emit light of at least two wavelengths through tissue; a detector configured to sense the light after it has passed through the tissue and to generate a signal indicative of the sensed light; a memory device configured to store at least one indication of sensor use information and at least one sensor life function, wherein the at least one sensor life function indicates to a separately housed patient monitor how to calculate a useful life of the sensor; and a communication port configured to communicate the at least one indication of sensor use information and the at least one sensor life function to the separately housed patient monitor, wherein the separately housed patient monitor calculates the useful life of the sensor using the at least one indication of sensor use information and the at least one sensor life function received from the sensor.
