Gyroscopes
Superior accuracy and stability over time and
temperature
STs innovatively designed sensors with different
combinations of analog and digital outputs provide
high performances. Our gyroscopes offer superior
stability over time and temperature, with a
resolution
lower than 0.03 dps/vHz for zero-rate level. This
guarantees the level of accuracy required by the
most
advanced motion-based applications.
These 3-axis gyroscopes have a single sensing
structure for motion measurement along all three
orthogonal axes, while other solutions on the
market rely on two or three independent
structures. STs
solution eliminates any interference between the
axes that inherently degrades the output signal,
thus
increasing the accuracy and reliability of
motion-controlled functionalities.
STs gyroscopes measure angular rate with a large
full-scale range (from 30 to 6000 dps) to meet the
requirements of different applications, ranging
from gesture recognition and image stabilization,
to
indoor and personal navigation. STs angular rate
sensors are already used in mobile phones,
tablets, 3D
pointers, game consoles, digital cameras and many
other devices.

Biometric Identification

• Reliable, low cost and convenient method of
  uniquely identifying individuals by measuring
  certain physical and behavioral characteristics
• This sample is then compared with the template or
  signature, based on the same characteristics
  established as unique identity of that individual
  and stored in the security system
• Characteristics Finger prints, Palm prints,
  Retina and iris patterns, face patterns, voice,
  gait.
