1. A noninvasive optical sensor configured to noninvasively monitor one or more physiological parameters of a wearer of the optical sensor, the optical sensor comprising:
- a plurality of emitters;
a detector configured to detect light attenuated by body tissue of a wearer of the optical sensor;
an emitter input configured to supply an emitter drive signal to the plurality of emitters;
a memory device; and
a communication device configured to receive sensor data to be stored in the memory device, wherein the communication device is configured to receive the sensor data over the emitter input.

Abstract
A pulse oximeter sensor may include reusable and disposable portions, and may include a connector adapted to electrically communicate with a physiological measurement instrument. Instrument port is in communication with the connector and provides communication with a sensor memory capable of storing sensor data, such as, for example, calibration data, emitter specifications, manufacturing data, and the like.
