MULTIPURPOSE SENSOR PORT
First Claim
1. A passive data storage device for communicating program instructions to a physiological monitor through a sensor port configured to communicate drive signals to light emitting device and receive signals from a detector indicative of light attenuated by patient tissue, the passive data storage device comprising:
- a connector configured to physically and electrically mate with a sensor port on a physiological monitor, the sensor port configured to communicate drive signals to a light emitting device and receive signals from a detector indicative of light attenuated by patient tissue;
a nonvolatile memory preprogrammed with program instructions, the program instructions when implemented by the physiological monitor providing updated operational instructions to be executed by the physiological monitor;
wherein the passive data storage device receives operating power from the sensor port.

Abstract
A sensor port is adapted to connect to either a sensor or a data source. A reader is configured to identify which of the sensor and the data source is connected to the sensor port. A data path is configured to communicate an analog signal associated with the sensor and digital data associated with the data source to a signal processor according to the identification made by the reader.
