Patent ID: 7437255

Claim:
A method for calibrating an acceleration sensor, said method comprising: providing a fixture that defines a first coordinate system; providing a chassis; orienting a plurality of sensor elements to form a misaligned coordinate system, wherein the misaligned coordinate system axes are oriented at other than right angles with respect to each other; coupling the sensor to be calibrated to the fixture; and mathematically compensating the misaligned coordinate system to correspond with the first coordinate system by determining a decomposed force vector using the formula {right arrow over (F)} i =A({I{right arrow over (S)}}{right arrow over (V)} i +{right arrow over (b)}), wherein {right arrow over (F)} i is the decomposed force vector, A is an alignment matrix, {right arrow over (S)} is a scale vector, {right arrow over (V)} is a voltage vector, {right arrow over (b)} is a bias vector, and I is an identity matrix.
