GETTING TO KNOW ALPHA MOTION TRACKER
__________________________________________________________________
1- Micro USB port
2- LED
Lightweight, high precision motion trackers that acquire and digitize patient
motion and communicate wirelessly with the Phoenix App.
They are available in four different colors (red, yellow, blue and green) with the
following scheme.
The motion trackers provide 3D angular velocity (by using gyroscopes), 3D
acceleration (by using accelerometers) and 3D earth magnetic field (by using
magnetometers). These are integrated using sensor fusion algorithms to provide
3D special orientation of limb segments.
These motion trackers were specifically designed to be used in a clinical or
ambulatory setting with a minimum need of calibration procedures.
The equipment may be supplied without a connector. Use a USB 2.0 Micro-B
(5pins) connector to plug into Micro USB port.
