STMicroelectronics has developed a sensing software system that filters and processes the data outputs from a 3-axis accelerometer, 3-axis gyroscope and 3-axis magnetometer.

Called the iNEMO Engine, it is designed to be used as a two-chip sensor solution (LSM303DLHx e-compass and the L3G4200D gyroscope) for mobiles and handheld terminals. 

The iNEMO software integrates a set of adaptive algorithms for prediction and filtering. The software takes data from the outputs of various motion sensors in smart consumer devices and integrates it so that the sensor outputs augment each other.

The software is designed to correct for magnetic distortions registered on the magnetometer, dynamic distortion measured by the accelerometer, and inherent drift over time of the gyroscope.

“This protects the accuracy of heading information, removes pointing inaccuracies and drift problems, and virtually eliminates timeouts for calibration,” said the supplier.
