Abstract
A sensor interface is configured to receive a sensor signal. A transmitter generates a transmit signal. A receiver receives the signal corresponding to the transmit signal. Further, a monitor interface is configured to communicate a waveform to the monitor so that measurements derived by the monitor from the waveform are generally equivalent to measurements derivable from the sensor signal.

2. A pulse oximetry device comprising:
-
a housing including at least a signal processor and a transmitter; a display positioned on the housing and in communication with the signal processor; a strap configure to securely mount the housing on an appendage of a user; a pulse oximetry sensor in communication with the signal processor and configured to be mounted to a finger of the user, wherein the pulse oximetry sensor includes at least; a light emitter configured to emit light into a tissue site of the finger of the user; and a light detector configured output a signal responsive to at least a portion of the emitted light after attenuation by tissue of the tissue site; and a cable configured to enable communication between the signal processor and the pulse oximetry sensor, wherein the cable is coupled to both the housing and the pulse oximetry sensor, wherein the signal processor is configured to; receive the signal from the pulse oximetry sensor; derive, from the signal, measurements of oxygen saturation and pulse rate; and display, on the display, the measurements, and wherein the transmitter is configured to; receive the signal from the pulse oximetry sensor; and transmit a transmit signal responsive to the signal to a receiver configured to adapt the transmit signal to a monitor-compatible signal based on characterization information specific to a monitor device, the monitor-compatible signal usable by the monitor device to provide physiological parameter measurements consistent with the signal received from the pulse oximetry sensor. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)
