Product Overview

The FAB System (Functional Assessment of Biomechanics) developed by BIOSYN SYSTEMS INC. CA is the worlds first full body wireless 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, gyros and earth’s magnetic field sensors and allow a real time detection of any angular displacement within biomechanical bodies. Powerful user-friendly software displays and calculates kinematic and kinetic data in real time and animates 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 under 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.

Analysis parameter selection screen

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. Skeleton or male/female models visualize the motion patterns 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. Depending on the card size it allows you to record numerous hours in the field without any range limitation.

Easy to use software

The software consists of a basic set-up system, a setup menu for test activities/motions, a signal and motion animation screen and data that is easily exported via excel format. 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:

• 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 systems 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 compatible software for customized analysis and statistics.

Technical specifications

Minimum Computer System Specifications for FAB System

Following are the current specifications for computer systems required for the Functional
Assessment of Biomechanics Systems shipped by Noraxon, upon which quotes may be based. These specifications are subject to change without notice due to the volatility of the computer industry. It may be assumed that systems shipped by Noraxon will meet or     exceed these specifications. Systems quoted with these specifications are good for three months after the date of the quotation.
