Abstract
A method of sensing includes obtaining first sensor data points by a sensor, obtaining first reference data points, and determining a correlation between the first sensor data points and the first reference data points. The method of sensing further includes measuring second sensor data points by the sensor, obtaining second reference data points, and adjusting the second sensor data points using the correlation and the second reference data points to obtain corrected sensor data points. The method of sensing also includes determining sensed values from the corrected sensor data points and storing the sensed values.

- obtaining second reference data points;
- adjusting the second sensor data points using the correlation and the second reference data points to obtain corrected sensor data points;
- determining sensed values from the corrected sensor data points;
- and
- storing the sensed values.
A method of sensing, the method comprising performing the following steps in real-time:
- obtaining, by a sensor, first sensor data points during a first time interval;
- obtaining, first reference data points during the first time interval;
- determining a relationship between the first sensor data points and the first reference data points by performing real-time regression analysis, the relationship comprising a set of correlation coefficients obtained from the real-time regression analysis;
- and
- during a second time interval and after the first time interval,
- measuring, by the sensor, second sensor data points,
- generating corrected second sensor data points by correcting for baseline variation in the second sensor data points using the relationship between the first sensor data points and the first reference data points, and
- determining sensed values from the corrected second sensor data points.
A method of sensing, the method comprising:
- obtaining, by a sensor, first sensor data points;
- obtaining first reference data points;
