Activities Ariel Dynamics Corporate Activities and Performances
Analog The Analog module is used as a general purpose laboratory data measurement and analysis sub-system. The module is designed to sample, save and present analog signals from many independent channels. A fast measurement rate is possible, with high resolution and programmable input voltage ranges. Data signals are measured to a 12 bit (1 in 4096) resolution. A number of triggering options are provided to assist in the capture of transient data and to allow the synchronization of the analog module with external events. The analog module also includes a set of specialized electromyogram (EMG) signal processing options. EMG data samples can be analyzed using a number of sophisticated techniques including spike analysis, signal rectification and integration, envelope processing and spectral analysis.
APAS The Ariel Performance Analysis System (APAS) is a software application suite for video-based biomechanical analysis. APAS supports both 2D and 3D analysis and includes automatic, semi-automatic, and manual digitizing.

Biomechanics Biomechanics is the study of the structure and function of biological systems by means of the methods of mechanics. which is the branch of physics involving analysis of the actions of forces. Within mechanics there are two sub-fields of study: statics, which is the study of systems that are in a state of constant motion either at rest (with no motion) or moving with a constant velocity; and dynamics, which is the study of systems in motion in which acceleration is present, which may involve kinematics (the study of the motion of bodies with respect to time, displacement, velocity, and speed of movement either in a straight line or in a rotary direction) and kinetics (the study of the forces associated with motion, including forces causing motion and forces resulting from motion)

Diagrams Wiring diagrams for our products.
Digitize Digitizing is the first step for analysis after the recorded images have been captured and stored on the hard disk of the computer. The Digitize module is a Windows based program for digitizing images to be analyzed using the Ariel Performance Analysis System (APAS). Digitizing can be performed in one of two modes, either Manual or Automatic. Manual digitizing is performed under computer control and the digitizing of video images is computer assisted. A trained operator with a reasonable knowledge of anatomy and a consistent pattern of digitizing can rapidly produce high-quality digitized images. Automatic digitizing requires some sort of visible markers. User input is minimal as the computer automatically tracks the markers based on color, contrast, position, velocity and acceleration.

Dynamometer The Resistive Exercise Dynamometer is a computerized, feedback-controlled, portable, battery-powered, hydraulic dynamometer which can be used in normal, reduced-g, and zero-g environments. The device provides a closed-loop feedback system to measure and control various muscular strength parameters.
EMG Electromyography (EMG) is a technique for evaluating and recording the electrical activity produced by skeletal muscles. EMG is performed using an instrument called an electromyograph, to produce a record called an electromyogram. An electromyograph detects the electrical potential generated by muscle cells when these cells are electrically or neurologically activated. The signals can be analyzed to detect medical abnormalities, activation level, recruitment order or to analyze the biomechanics of human or animal movement.
Exercise Machine The Ariel Computerized Exercise System is the most unique system and advanced technology on the market today. The personal computer approach to the practice of resistance exercise is a quantum change in both thinking and application. The "artificial intelligence" in the technology puts resistance exercise into a broad new realm of possibilities for physical conditioning, sports training, rehabilitation, medical evaluation, research and executive fitness.
FAQ Consult our database to find the answers you are looking for.
Favorite Some of our personal favorites.
Filter APAS/Filter is used to remove small random digitizing errors or "noise" from the transformed image sequence. The digitizing process involves measuring the location of each body joint. As with any type of measurement, there is no correct value, only an estimate to some known level of accuracy. Therefore, each measurement consists of two parts: the actual or true value, plus an error value due to the inability to perform exact measurements. This module will improve digitized joint locations by minimizing the effect of the errors made during the analysis process. In addition to the displacement curves, it can display velocity and acceleration curves for each component. By viewing the acceleration curves, the extent of random error remaining in the data can more easily be determined.
Force Plate Force platforms or force plates are measuring instruments that measure the ground reaction forces generated by a body standing on or moving across them, to quantify balance, gait and other parameters of biomechanics. Most common areas of application are medicine and sports.
Gait APAS/Gait is an add-on module to the APAS System. It allows full-fledged gait analyses using industry-standard marker sets. It is a video-based system for the most accurate kinematics analyses in the industry, and optionally uses input from force plates for inverse dynamics analyses. APAS/Gait generates standard charts and standard analysis reports with a click of a button. APAS/Gait uses 3-dimensional rendering of the kinematic data in real-time; this allows you to visually validate anything you are doing. If you inadvertently input a wrong anthropometric measure, or if your data contains errors of any kind, you will be able to spot this immediately in the 3D display.

Quaternions Our applications make extensive use of quaternions. In mathematics, the quaternions are a number system that extends the complex numbers. Quaternions find uses in both theoretical and applied mathematics, in particular for calculations involving three-dimensional rotations such as in three-dimensional computer graphics and computer vision. They can be used alongside other methods, such as Euler angles and rotation matrices, or as an alternative to them depending on the application.
Renderer APAS/Renderer is an add-on module to the APAS System that lets you render 3-dimensional kinematic data in real-time. This module is a valuable addition to standard "stick figure" displays because rendered 3D models can convey more information about segment orientations than stick figures.

Sports Sports Biomechanics is a quantitative based study and analysis of professional athletes and sports' activities in general. It can simply be described as the Physics of Sports. In this subfield of biomechanics the laws of mechanics are applied in order to gain a greater understanding of athletic performance through mathematical modeling, computer simulation and measurement. Biomechanics is the study of the structure and function of biological systems by means of the methods of mechanics. which is the branch of physics involving analysis of the actions of forces.
Steroids Anabolic steroids, technically known as anabolic-androgen steroids (AAS) or colloquially as "steroids" (or even "roids"), are drugs that mimic the effects of testosterone and dihydrotestosterone in the body. Uses of anabolic steroids in sports are controversial because of their adverse effects and the potential to gain an advantage conventionally considered "cheating."
