Abstract
A method of factory calibrating a police radar/laser detector including a controller, an accelerometer, and a memory, by manipulating the detector to rotate the accelerometer, measuring and feeding real time measurements from the accelerometer to a Least Squares Elliptical Fit algorithm executed by the controller, applying the Least Squares Elliptical Fit algorithm to the real time measurements to find the equation of an ellipse formed by the measurements, storing the coefficients of the ellipse in the memory. The coefficients are then recalled from the memory to thereby calibrate the accelerometer.
