STMicroelectronics, a supplier of micro-electro-mechanical systems (MEMS ) devices, is set to display its motion sensor technologies including optical image stabilization (OIS) and location-based services (LBS).
ST said it will reveal a new approach to deliver OIS to mobile phones.
OIS uses feedback from motion sensors embedded in the mobile device to control the mechanical actuator that compensates for slight movements of the user’s hand, resulting in sharper images even in low-light conditions.
The new technology utilizes actuators made of shape memory alloys (SMA) that provides the ability to contract upon heating.
LBS are mainly designed to locate the mobile device in urban canyons and indoor environments, where the signals from the global navigation satellite systems (GNSS) satellites are blocked.
The company said in order to improve the accuracy of the position calculation by an order of magnitude, it will demonstrate a solution that fuses data from motion sensors with other data from map databases and Wi-Fi access points.
The solution includes an iNEMO Inertial Measurement Unit that offers 10 degrees of freedom, combining 3-axis sensing of linear, angular and magnetic motion with temperature and barometer/altitude readings.
The company said it will showcase its latest innovations on 27 February – 1 March 2012 at the Mobile World Congress (MWC) in Barcelona.
