STMicroelectronics unveiled the advanced filtering and predictive software engine, iNEMO. The new engine fuses the outputs from a 3-axis accelerometer, 3-axis gyroscope and 3-axis magnetometer using advanced algorithms.
The output got from the iNEMO is more accurate and dependable; these features are the need of the hour in many motion-based applications. Emerging new applications like location-based services, enhanced motion-based gaming, robotics etc require more than one MEMS sensors to achieve accuracy, resolution and fast response time. The iNEMO is designed keeping such new trends in mind.
IiNEMO engine
Benedetto Vigna is the Group Vice President and General Manager of ST's MEMS Sensors and High Performance Analog Division. He claimed that the iNEMO engine’s software contains complex algorithms for filtering and prediction, therefore the customers are freed from the hassle of coming up with the algorithm. The function of the software is to fuse various sensor outputs so that the individual outputs augment each other. The algorithm is capable of correcting magnetic disorders and inherent drift over time of gyrometers. Such sophistication in the software of iNEMO provide greater accuracy in the applications.
The iNEMO Engine is currently made available to two major consumers’ manufacturers through the ST sales channels. The iNEMO can be integrated into mobile platforms using a two chip sensor solution (LSM303DLHx e-compass and the L3G4200D gyroscope). More advanced versions of the iNEMO that can be used with mobile devices that use ST’s iNEMO multi-axis sensors are expected to be ready for production by the end of this year. ST also has a broad range of MEMS sensors like accelerometers (to measure linear acceleration and gravity) gyroscopes (to measure angular velocity) and magnetic sensors that can be integrated with the iNEMO engine.
