The Computerized Exercise System (CES), developed by Dr. Gideon Ariel, a renowned authority in biomechanics, represents the state-of-the-art in technology for medical diagnostics, physical therapy and rehabilitation, sports medicine evaluation and treatment, fitness training, and research. The CES is a computerized exercise system that automatically monitors, controls and modifies resistance and velocity, while in use. It does so safely and efficiently, constantly adjusting itself to each person's individual capabilities and limitations, and may be used isotonically, isokinetically and isometrically. It is uniquely interactive, and the only exercise system available with so many capabilities.

The CES also records accurate measurements of movement, strength and endurance with the capacity for storage and subsequent comparison of the individual's performance.

Rest assured that the CES is not difficult to use. It has been designed to remove much of the burden of exerciser program selection for the inexperienced user, while at the same time providing advanced training and diagnostic tools to the coach, trainer or clinician.

Regardless of your level of experience, prior knowledge of computers or data processing is not necessary. Performing a personalized training or rehabilitation program is accomplished by following simple directions on the monitor and entering proper selections provided by the menu driven system. Even the most advanced features of the CES can be mastered in a few practice sessions.

1.1 User Adaptive

The CES is designed to adapt to the specific needs of each user. The stations provide maximum comfort and support to all body types and sizes by having a variety of adjustments. The passive hydraulic system automatically adjusts it's resistance to the user, accommodating the user's effort throughout the range of motion. The CES also allows each station to be used for a multitude of different exercises for various body parts.

1.2 Bi-directional, Bilateral of Unilateral Exercise

The CES can perform all exercises with independently programmed resistance or speed on the upstroke as well as the downstroke. This means that more than one muscle group can be trained by a single exercise. Bi-directional training can also be utilized during unilateral or bilateral training. The bi-directional capacity of the CES allows the user to maximize the productivity of their time.

1.3 User Friendly Operation

Operation of the CES is guided through a system of menus and guides that will provide a clear set of options at every point in the operation of the CES. A brief signing on and off procedure allows the user to quickly switch stations and continue their training.

1.4 Advanced Self Sustaining Structure

The CES is the only exercise system that equips itself with a self maintenance module. This maintenance module allows calibration of the exercise stations, the performance of systems utilities, and the running of diagnostics in the unlikely event of a malfunction. All these features function directly out of the same user friendly menu driven mode that operates the rest of the CES.

1.5 CES Environment

The CES Environment is designed for maximum simplicity in operation so that even someone who is not familiar with computers can operate the system. The CES is a window based system that relies on one word or one button to represent the most commonly used commands.

1.5.1 Mouse

To even further simplify operating the CES, there are three buttons located at the top of the mouse which will perform the three most common functions. From left to right; key #1 is the Enter button, key #2 is the End button, which indicates that the operation is ended and to exit the screen, key #3 performs the same function as F10, which begins the exercise. The Escape key is used to abort an exercise without completing it. The mouse performs this same function when buttons #2 and #3 are pressed simultaneously. Pressing buttons 1, 2, 3 together will cause a template with all the special functions to appear at the bottom of the screen. The mouse can then be used to select any of these different special functions.

1.5.2 Special Function Keys

In the various menu's you will notice that there are a series of commands that are followed by the names of keys. These keys are special function keys for heavily used commands. For example, F1 is used to change the drive, change station, calibration check, or to set stick points while exercising. This allows for the quick execution of commands through the pressing of a single key.

1.5.3 Arrow Keys

The left/right arrow keys and the space bar allow the user to move the cursor through the different options or fields of the screen. The active areas will become highlighted as the cursor moves through them. By pressing the "Enter" key a choice can be selected within the fields.

The up/down arrows can be used to scroll options within a field. The up/down arrows can also change numeric values within a field. After the desired value is reached the Enter key must be pressed to save the change.

1.6 Feedback Mechanisms

The CES is equipped with a feedback mechanism that assists the user during the performance of an exercise. These feedback mechanisms help the user know when they have completed a full extension and flexion for an exercise. These feedback mechanisms also tell the user when they have completed a full repetition and when they have completed an exercise set.

1.6.1 Visual Feedback

Visual Feedback is given by the color monitor during exercise. A green column located at the left of the screen indicates the position of the bar during the exercise. The center of the column is solid only where the range of the exercise has been set, allowing the user to follow the position of the bar through the range of motion. At the right of the screen the results of each repetition are displayed as they are completed. Overall averages for the exercise set are displayed at the completion of the set.

1.6.2 Audio Feedback

Audio feedback is given in the form of a beep at the end of each full extension and flexion. The pitch of the tone rises during an increase in performance and lowers during a decrease in performance. A tune is played at the end of each exercise set. This allows the user to remove all their attentions from the screen during the exercise, if necessary.

1.6.3 Mechanical Feedback

After each full repetition there is a slight release in the resistance of the bar, followed by a gradual breaking of the bar. This gives the user another indication that they have completed full extension of flexion of the exercise.
