AmmSensor™ is a revolutionary new real-time wireless 3D sensor that is Bluetooth enabled. This 3D (9 Degrees-of-Freedom (IMU = Accelerometer: Ax, Ay, Az; Gyroscope: Gx, Gy, Gz; Magnetometer: Mx, My, Mz; 250Hz ++)) inertial measurement unit (IMU) samples at 250Hz and provides motion data by employing three miniature tri-axial MEMS chips to capture acceleration, the earth’s magnetic vector and angular velocity. AmmSensor™ combined with AmmGraph3D™ software will capture and display both the raw sensor signals:

AmmSensor™ is the most versatile, lowest cost Bluetooth enabled IMU/sensor in the world today! It can measure human motion, machine motion or any motion! AmmSensor™ has been designed for high speed sports motion (2000d/s and 12g) but can easily be switched to measure slower motion for rehabilitation applications (400d/s and -4g). The attractive slim line package can easily be worn on the wrist, leg, around the waist or on any part of the body!

AmmSensor™ can be used in many life science areas and in a myriad of industrial applications: • Biomechanics Research Motor Control • Rehabilitation • Biomedical Engineering • Sports • Physical Therapy • Psychology • Neurology • Educational Demonstrations, e.g. Physics Classes. Also in: • Aging • Slip and Fall • Gait • VR • Forensic Medicine • Augmented Reality • 3D Simulation Training • Gaming Industry • Ergonomics • Aerospace • Automotive • Marine • Military.

AmmSensor’s output can be changed between binary and ASCII by the user. Binary mode provides 250 complete samples per second, whereas ASCII output is 125 samples per second, and is intended for ease-of-use with any terminal program that can receive 115 KBaud data. The software also computers unit vectors of the sensor’s orientation. From these unit vectors many different 3D angle sets can be computed; such as Euler angles, Cardan Angles etc. These data are transmitted from the AmmSensor™ in real-time to a Windows compatible laptop. AmmGrraph3D™ allows for capture to a comma delimited file, which opens MS Excel to display and save the current data.

Write your own programs in most languages: VB, C#, C, Matlab and Labview using a simple software demonstration program in VB that we provide. Since the AmmSensor™ uses Bluetooth you could even develop programs of your own for Windows Mobile, iPhone or Droid smart phones. This allows for ultimate portability.

AMM3D Optical Golf

AMMCORE™ and Captor™ software calculate the biomechanical parameters from the captured motion data and then present the user with tables, graphs and animated 3D motion sequences. The AMM3D OPTICAL 3D-GOLF™ analysis systems measure, analyze and provide data that sports, fitness and medical professionals use to study, understand and improve human motion.


AmmTrainer3D™ plus AmmSensor

AmmTrainer3D™ plus AmmSensor™ uses real-time audio biofeedback tones to allow the golfer to feel the correct or wrong positions at all the key points during the swing. If the golfer is overturning the hips set the tone to bad and set the range to 60 to 120 now the phone will beep when the golfer overturns. The tone could be pleasant or obnoxious (negative tone); this allows the use of both positive and negative feedback.


AmmTrainer3D and AmmSensor on Hand Held PC

It runs on both a laptop and a hand-held PC so you can take it with you, put the hand-held PC in your pocket and the sensor anywhere on your body and go to the driving range and practice your correct movements. The application is called AmmTrainer3D and it allows you to trained to feel different body positions by giving you an audio tone when you are in the correct position.



This enables such applications as motion biofeedback or motion data logging with the sensor on your body, talking directly to a cell phone on your hip or a laptop on the desk. AmmSensor™ has been designed for high speed sports motion but can easily be switched to measure slower motion for rehabilitation applications.



From down-under, to the Olympics, and now to the world from our headquarters in Phoenix, Arizona, AMM provides three world-class, 3D motion capture and analysis solutions to help you understand and improve golf swing efficiency. Advanced Motion Measurement has a full line of motion capture and motion measurement products based on the study of biomechanics.
