iNEMOENgine

The iNEMOENgine_PW8 software package includes the iNEMOENgine library.

The iNEMOENgine is a new, advanced software engine that fuses accelerometer,

gyroscope and magnetometer data to deliver accurate and reliable motion-sensing

information that is easy to integrate into smart consumer devices.

The iNEMOENgine fuses data from the integrated 9-axis sensor suite with advanced

algorithms that use true high-number-of-states adaptive Kalman filtering.

The iNEMOENgine’s adaptive filters converge so that correct heading data overrides

magnetic distortions and anomalies, resulting in more accurate and reliable data.

iNEMO allows the correction of:

●

magnetic distortions registered on the magnetometers

●

dynamic distortion measured by the accelerometers

●

inherent drift of the gyroscope over time

The iNEMO engine integrates all 9 inertial axes plus compass with complex fusion

algorithms, so the output of the sensor cluster is optimized.

This allows for faster, easier integration into smart consumer devices and higher

performance of the solution as a whole.

Library output:

●

Quaternions four number hpr system

●

Rotation: heading, pitch, and roll

●

Linear acceleration: device frame linear accelerations

●

Gravity: device frame gravity acceleration
