Abstract
A MEMS type sensor is used for measuring a particular parameter on an IC chip within an electronic device, such as music player, a smart cellular telephone, etc. The parameter may be a scalar parameter, such as a directional orientation indicative a current compass point, or a multidimensional vector parameter, such as a three-dimensional acceleration. The sensor output is recalibrated using stored coefficients when ambient conditions vary. The stored coefficients may be modified during calibration.
