Oximeter sensor with digital memory recording sensor data

An oximeter sensor comprising:

• a light emitting element;
• a light detecting element;
• and
• a memory device for storing digital data, said digital data comprising updated code or coefficients for use by an oximeter monitor coupled to said oximeter sensor to calculate data encoded in signals received from said light detecting element.

An oximeter sensor comprising:

• a light emitting element;
• a light detecting element;
• and
• a memory device for storing digital data, said digital data comprising a displayable message.

A method for storing data in an oximeter sensor, the method comprising:

• emitting light from a light emitting element;
• detecting light from the light emitting element using a photodetector;
• and
• storing digitally encoded data in a memory in the sensor, the digitally encoded data comprising a maximum safe drive current that can be applied to said light emitting element in said memory.
