Broadcom's Hybrid Universal Location Application, HULA, uses Kalman filters to compensate for errors in individual sensors, resulting in more accurate location tracking (bottom right) that can be achieved with a magnetometer (upper right) or a gyro (bottom left). (Click here to enlarge image.)
ST Microelectronics is having one of the best periods of its existence, thanks to MEMS. It is taking down giants like Freescale with innovative and cost efficient MEMS designs. Will be good to read what they have in mind for MEMS in the future.
