N-USE AUTOMATIC CALIBRATION METHODOLOGY FOR SENSORS IN MOBILE DEVICES
First Claim
1. A method of calibrating an accelerometer in a portable device comprising:
- receiving data from the accelerometer;
providing accelerometer samples from the data based upon one or more selection rules that adaptively selects data that satisfy certain criteria;
fitting the accelerometer samples to a mathematical model; and
providing a bias of the accelerometer based upon a center of the mathematical model.

Abstract
A method, system and computer readable medium for calibrating an accelerometer in a portable device is disclosed. The method, system and computer readable medium comprises receiving data from the accelerometer, and providing accelerometer samples from the data based upon one or more selection rules that adaptively selects data that satisfy certain criteria. The method system and computer readable medium also includes fitting the accelerometer samples to a mathematical mode. The method system and computer readable medium further includes providing a bias of the accelerometer based upon a center of the mathematical model.
