productroundup SENSORS/TRANSDUCERS Geomagnetic mod- ules extend battery life and boost accuracy in mobile compassing Experts in Electronic Adhesives & Encapsulants igation and location-based services in portable consumer systems by inte- grating high-resolution, three-axis sensing of linear and magnetic motion in a 5×5×1-mm package. Each module features 6-D orientation detection and two programmable interrupt sig- nals that enable immediate notifica- tion of motion detection and free fall. Operating power consumption is 360 μA, and the device provides output across full-scale ranges of ±2, ±4, and ±8g for linear acceleration and ±1.3 to ±8 gauss for the magnetic field.
