ST sensor embeds complex motion-recognition capabilities
11/3/2011 2:51 PM EDT
is touting its latest sensor as the industry's first three-axis high-resolution accelerometer with two embedded finite-state
These programmable blocks enable custom motion recognition
inside the sensor, reducing system complexity and power consumption in
motion-sensitive mobile phones and other smart consumer devices that let users
answer calls, turn the ringer on or off, or launch applications like a
pedometer, with a defined motion.
The embedded finite-state machines allow the user to
implement customized motion-detection-based applications with a high level of
flexibility, reducing the workload of the microprocessor by moving programming
functionality inside the sensor. These basic programs identify specific motions
or gestures, custom-defined in the instruction set that runs inside the sensor
firmware, and initiate associated actions or applications.
ST's LIS3DSH accelerometer provides accurate output across full-scale ranges of
Â±2g/Â±4g/Â±8g/Â±16g and boasts excellent stability over time and temperature.
Other features include power-down and sleep modes, an embedded FIFO (first-in
first-out) memory block, a temperature sensor, and a self-test function.
