| titleOfInvention | Oxygen concentration meter crosstalk reduction |
| abstract | A method and apparatus for reducing crosstalk in an oximeter. The oximeter includes a band pass filter. The amount of crosstalk through the bandpass filter is approximated. Based on this approximation, the corner frequency of the bandpass filter is adjusted if it is designed to minimize crosstalk. In one embodiment, the calibration mode is performed when the sensor is attached to an oximeter. In calibration mode, the signal is first measured when only the red LED is on and then only when the IR LED is on. Any signal that is measured in the off channel is assumed as a result of crosstalk from other channels. The magnitude of the crosstalk is determined as a percentage, then the percentage is multiplied with the actual signal as a crosstalk compensation and subtracted from the other LED signals. |
