The method of claim 14, comprising receiving control signals from the separate monitor, the control signals activating the light emitting element to pulse the light signals. 16. The method of claim 14, comprising preventing erasure of stored data. 17. A method for monitoring sensor data with a monitor, comprising: providing control signals to a light emitting element of a sensor;reading signal data from a photo-detector of the sensor;processing the signal data to obtain physiological data;compressing the physiological data;writing or attempting to write the compressed physiological data to a memory in the sensor; andusing information in a field of the memory in the sensor to disable display of data from the memory, wherein the information in the field is set by reprocessing of the sensor. 18.
