Product Overview
The FAB System (Functional Assessment of Biomechanics) developed by BIOSYN SYS-TEMS INC. CA is the worlds first full body motion capture system based on “camera free” inertial sensor technology. This innovative technology allows completely free movement without the need to stay in view of cameras. Inertial sensors combine accelerometers, gy-ros and earth magnetic field sensors and allow a real time detection of any angular dis-placement within biomechanical bodies. Powerful software displays and calculates kine-matic and kinetic data in real time and animates the body motion with selectable graphical models.

Operation of the system
Up to 13 small, light weight sensors (4x7x2,4 cm) are attached to user selectable body segments including head, upper/lower arm, thoracic trunk, pelvis, thigh/ shank and weight/force sole sensor. Elastic straps guarantee a stable fixation. The sensors can be attached below or above clothes. An auto-calibration routine guarantees quick and easy use even for the novice. The system is ready to start within 5 minutes.

Signal transmission and real time display
In wireless real time mode all data are collected at 100 Hz sampling rate and transmitted to small receiver system with USB PC connection. The transmission range is 20 meters. All kinematic and kinetic data are processed and optionally displayed in real time. Skele-tons or male/female models visualize the motion pat-terns from up to 3 different views.
Data logger option
The small receiver box can also be used as a belt datalogger. An onboard control panel allows to setup the whole system in the field and without PC. After calibration it stores data on a commercial SD flash card. Dependent on the card size it allows you to re-cord numerous hours in the field without any range limitation.Powerful automatic software analysis
The software consists of a functional database system, a setup menu for test activities, a signal and motion animation screen and customized reports. The motion capture data are processed automatically. The following categories of analysis parameters are supported for all detected body segments and can be selected for signal review:
Analysis parameter selection screen
- Angle Data
- Force Data
- Torque Data
- Velocity
- Acceleration
- Power
- Foot sole – Pressure
- Foot Sole Weight
The angle data are based on the pitch, roll and yaw system for each detected segment, the kinetic data are based on an optimized rigid body model, the weight and pressure data are calculated from the force in-shoe sole.
A re-play function allows you to review each recording and activity. Virtual tools allow you to visualize the range of motion, force vectors and moments and motion patterns of each segment relative to center of the model. All parameters/signals can directly be exported to Excel for customized analysis and statistics.
