Abstract
A method for operating an oximeter sensor, and corresponding apparatus, which includes an encoded temperature characteristic of a light emitter in the sensor. The encoded temperature characteristic is read, and is used to modify a drive of the light emitter in the sensor. This enables a light emitter to be operated at its maximum allowable intensity to maximize a signal to noise ratio, without burning a patient, in accordance with the particular characteristics of that light emitter.
