Unveils Next-Generation iNEMO Engine; Enables New Level of Motion-Sensing Applications on Smart Consumer Devices
Exciting fusion of motion-sensor data gives smartphone
and gaming devices new utility and features
Geneva, March 24, 2011 – STMicroelectronics
today unveiled first details of its new iNEMO Engine.
An industry first, the iNEMO’s new advanced filtering
and predictive software engine integrates the outputs from
a 3-axis accelerometer, 3-axis gyroscope and 3-axis magnetometer.
Fusing these sensors’ data through sophisticated algorithms,
the iNEMO delivers dramatically more accurate and reliable
sensor performance – the kind of performance now in
demand by makers of next-generation smart consumer devices
for a host of new motion-based applications.
For many current applications, such as freefall detection,
screen rotation or pedometers, a single MEMS accelerometer
meets their system requirements. However, a new class of advanced
applications is emerging, for example: location-based services,
enhanced motion-based gaming, pedestrian dead-reckoning for
indoor and multi-floor navigation, robotics or human-body
tracking. These applications require multiple MEMS sensors,
together with advanced software, to achieve better overall
system performance in terms of accuracy, resolution, stability
and response time.
“The iNEMO Engine delivers a quantum leap in the performance
level required by next-generation smart mobile devices to
enable a myriad of new exciting applications,” said
Benedetto Vigna, Group Vice President and General Manager
of ST’s MEMS, Sensors and High Performance Analog Division
“It also lifts the burden of complex sensor algorithm
development off the shoulders of our customers.”
The iNEMO Engine software integrates a set of highly sophisticated
adaptive algorithms for prediction and filtering. The software
takes data from the outputs of various motion sensors in smart
consumer devices and integrates it so that the sensor outputs
augment each other, leapfrogging what individual sensors can
do alone. The software can correct for magnetic distortions
registered on the magnetometer, dynamic distortion measured
by the accelerometer, and inherent drift over time of the
gyroscope. This protects the accuracy of heading information,
removes pointing inaccuracies and drift problems, and virtually
eliminates timeouts for calibration.
The iNEMO Engine is available now to major consumer manufacturers,
upon request via the usual ST sales channels, for integration
into leading mobile platforms in a two-chip sensor solution
(LSM303DLHx e-compass and the L3G4200D gyroscope). Advanced
new mobile devices using ST’s iNEMO Engine multi-axis
sensors are expected to be in production at leading consumer
manufacturers before the end of the year.
In addition, ST’s has a wide range of highly accurate
MEMS sensors available for the iNEMO Engine. These sensors
include accelerometers to measure linear acceleration and
earth gravity, gyroscopes to measure angular velocity, and
magnetic sensors that output reliable heading information.
About ST’s MEMS Devices
ST’s MEMS accelerometers and gyroscopes have enabled
motion-activated user interfaces in a number of popular consumer
devices, including game consoles, smart phones and remotes.
Also, computer manufacturers widely use the Company‘s
acceleration sensors for free-fall protection in laptop hard-disk
drives. ST shipped its one billionth MEMS sensor in November
and its dedicated 8-inch MEMS fabrication line, which was
among the first in the world, currently produces more than
1.5 million devices a day.
