Hello Laura,
Thank you for your interest in the Ariel Performance Analysis System (APAS).  The APAS is a 3D video-based movement analysis system which accurately quantifies function and provides objective data the professional may use to justify or evaluate treatment.  Areas of successful application for the APAS include human performance, injury and rehabilitation assessment, quantification of loss for compensation claims, equipment and product testing and development, determination of potential or actual risks for products and activities in liability litigation, as well as applied research in the areas of orthopedic medicine, therapeutics, and physical training.

The APAS integrates state-of-the-art computer and video processing hardware with specialized software modules that perform data collection, analysis, and presentation.  Objective quantifiable documentation is provided for both 2-Dimensional and 3-Dimensional analysis.  Specific points of interest can be digitized with user intervention or automatically using contrasting markers.  Stick figures are then generated and can be synchronized with kinematics data.  Additionally, up to 32 channels of analog data (i.e. force platform, EMG, goniometers etc.) can be synchronized with the kinematics data.

The APAS product information can be found on the Ariel internet site (/).  The direct address to several areas that might be of interest are listed below.

Hello Rizal,
Thank you for your message.  When you enter the SITE KEY provided by Ariel
Dynamics, that will activate the software license for unlimited use.  It is
perfectly normal for the Site Code information to change.  This has nothing
to do with your being able to operate the software.

When you open any of the APAS software modules (Display for example),
youwill see a brief message stating "Unlimited License".  If you press the
ENTER key when this message is displayed, you will access the license
information.  Once you have entered the SITE KEY, you do NOT need to press
the ENTER key anymore.

When you open the software module, the "Unlimited License" menu will display
briefly.  Just wait a few seconds and it will dissappear and the software
module will open.

Also note that the Analog module is an optional software module that was not
specified with the original order.  In order to perform a video analysis,
you should use the modules in the following order.

   Digital Video capture software (this is provided with the DV frame
grabber hardware)
   TRIM Module (used to "clip" the desired video for analysis)
   DIGITIZE Module (used to digitize the data and calibration points)
   TRANSFORM Module (used to convert that data to spatial coordinates)
   DISPLAY and/or APASVIEW Module (used to display analysis results)

I hope this information is helpful.  Please contact me for any additional

Subject: Re: Attn John Probe (Site Key)


sorry to bother you again. i keyed in the key into the analog module and
everything when well, so i closed the module and went on to another module,
but when i displayed the site code it displayed a whole new code! it was the
same with all the other modules, now even the analog module got a new code
and is unlicensed. and when i displayed the system check it also gave out a
new parameter...everytime i opened it a new one. the current parameter and
code is

Parameter: 8CE7D495CDB55590
cODE : D617 FC5D 7FCA 88D0 7B

Thanks for your help

Hello Rizal,

Thank you for your message.  It was no trouble to provide the APAS CD.  I
hope the installation occurred smoothly!  Based on the information you have
provided, a SITE KEY has been generated for the APAS computer system.

   System Parameter:   B8A311-F8A9D-11FFE
   Site Code:     D64F-847D-7FCA-D036-FB
   SITE KEY:   FF07 49A9 67C2 2BDD F360 DD32 CC

NOTE:  Please do not reformat the hard drive, upgrade the operating system
or change the directory structure of the APAS system files as this will
invalidate the software license.

Please keep us informed with your progress using the APAS.  We look forward
to working with you and would be happy to answer any questions.
