Abstract: A tailored 3-D integrated accelerometer theoretical model is established, and a corresponding accelerometer with higher sensitivity is proposed and demonstrated experimentally. Based on the ...

Abstract: An accelerometer can be used to calculate pitch and roll orientation angles. However, the accelerometer sensor cannot calculate the yaw angle, so a novel approach is needed to calculate the ...

STMicroelectronics is aiming at healthcare wearables with an IC that senses bio-potentials and acceleration, and includes an AI processor and a finite state-machine for pedometer, step detection and ...

// r is meaningful only when the device is not free-falling and it is not close // to the magnetic north. If the device is accelerating, or placed into a // strong magnetic field, the returned matricx ...
