Semiconductor company STMicroelectronics has released iNEMO Engine Sensor Fusion Suite, a series of modules of advanced filtering and predictive software that utilizes complex algorithms that can integrate multiple outputs from different MEMS sensors.

Real-time on-board motion-sensor data fusion is set to increase accuracy, resolution, stability and response time in advanced motion-based applications in consumer, computer, industrial and medical fields.

The iNEMO Engine can be combined with ST's iNEMO Inertial Modules to create complete and customizable hardware/software multiaxis MEMS sensor solutions for enhanced motion and accurate heading recognition. Equipment manufacturers across different market segments can now easily and quickly deploy robust and reliable high-performance motion-detection systems with up to 10 degrees of freedom, comprising three-axis sensing of linear, angular, and magnetic motion with barometer/altitude readings from a pressure sensor, enabling true augmented-reality applications.


The iNEMO software automatically corrects measurement distortions, inaccuracies and interference among the sensors.

Based on the Kalman Filter theory (an algorithm that predicts the current state of the system from its previous state and current measurement), ST's iNEMO Engine software employs a set of adaptive prediction and filtering algorithms that make sense of all the complex information coming from multiple sensing devices, including accelerometers, gyroscopes, compasses, and pressure sensors. The software automatically corrects measurement distortions, inaccuracies and interference among the sensors.

"The iNEMO Engine's sensor-fusion capabilities unleash the full capabilities of ST's MEMS sensors and multiaxis inertial modules," said Benedetto Vigna, corporate vice president and general manager of ST's analog, MEMS and sensor group. "Unparalleled integration of motion-sensing software and hardware in customizable system solutions keeps ST ahead of the competition and accelerates the company's mission to make MEMS ubiquitous in all facets of life."

ST's iNEMO Engine Sensor Fusion Suite includes the iNEMO Engine Lite, a free software library for motion-detection system evaluation, and the iNEMO Engine Pro, a compiled software library with data-fusion algorithms for multiple sensor output processing, customizable for different operating systems and hardware platforms.
