ST Microelectronics introduces its new iNEMO Engine sensor fusion software designed for use in motion-sensing applications in smart consumer devices.
ST Microelectronics is a global semiconductor leader serving customers across the spectrum of electronics applications and a major supplier of MEMS (Micro-Electro-Mechanical Systems) sensors for consumer and portable applications.
The innovative iNEMO’s new advanced filtering and predictive software engine integrates the outputs from a 3-axis accelerometer, 3-axis gyroscope and 3-axis magnetometer.
Fusing the data from these sensors through sophisticated algorithms, the iNEMO Engine sensor fusion software delivers more accurate and reliable sensor performance that is now in demand by makers of next-generation smart consumer devices for a host of new motion-based applications.
Single MEMS accelerometers may meet the system requirements of current applications such as freefall detection, screen rotation or pedometers.
But emerging applications including location-based services, enhanced motion-based gaming, pedestrian dead-reckoning for indoor and multi-floor navigation, robotics or human-body tracking require multiple MEMS sensors and advanced software to achieve better overall system performance in terms of accuracy, resolution, stability and response time.
According to Benedetto Vigna, Group Vice President and General Manager of ST’s MEMS, Sensors and High Performance Analog Division, the iNEMO Engine sensor fusion software delivers a quantum leap in the performance level required by next-generation smart mobile devices to enable multiple applications.
Additionally, iNEMO also lifts the burden of complex sensor algorithm development off the shoulders of customers.
Key features of the iNEMO Engine sensor fusion software:
- Integrates a set of highly sophisticated adaptive algorithms for prediction and filtering
- Integrates data from the outputs of various motion sensors in smart consumer devices so that the sensor outputs augment each other
- Corrects magnetic distortions registered on magnetometers, dynamic distortion measured by accelerometers and inherent drift over time of gyroscopes
- Protects the accuracy of heading information, removes pointing inaccuracies and drift problems, and virtually eliminates timeouts for calibration
The iNEMO Engine is available now to major consumer manufacturers for integration into leading mobile platforms in a two-chip sensor solution.
Advanced new mobile devices using ST’s iNEMO Engine multi-axis sensors are expected to be in production at leading consumer manufacturers shortly.
ST also offers a wide range of highly accurate MEMS sensors for the iNEMO Engine including accelerometers to measure linear acceleration and earth gravity, gyroscopes to measure angular velocity, and magnetic sensors that output reliable heading information.
