A calibration process utilizes two nearly identical sensors. The characteristic output curve of the first sensor is obtained using the measuring outputs of the second sensor. In particular, the first sensor has a characteristic output curve f[x] where x is a physical variable to be measured. The second...http://www.google.fr/patents/US5276631?utm_source=gb-gplus-shareBrevet US5276631 - Process for automatic calibration or re-calibration of measurements of a physical variable
