Claim 0:
1. A reusable noninvasive physiological sensor configured to store sensor use information 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 an indication of sensor use information and an indication of which function to use from an array of functions that are configured to be used in determining a useful life of a plurality of sensor types; and
a communication port configured to communicate at least the signal indicative of the sensed light, the indication of sensor use information and the indication of which function to use from the array of functions to a patient monitor, wherein the patient monitor is configured to calculate the useful life of the sensor based at least in part on the indication of which function to use from the array of functions.
