  • CODA & CODAS Info

    Dear Biomech-L Subscribers,

    Recently, I requested input from those who knew anything about a CODA or
    CODAS system. Below are the responses. Thanks to all who responded.

    Bob Redd

    Hi Bob,
    We have two AT-CODAS systems in our department and I have found the
    data acquisition software to be excellent. As far as I know the
    manufacturer is: DATAQ Instruments, Inc.
    150 Springside Dr., Suite #B220
    Akron, Ohio 44333
    Telephone: (216) 668-1444
    Fax: (216) 666-5434

    Best of Luck, Jim Dowling

    Bob/Dan:

    Just by coincidence, the following message appeared on the net just after
    you posted your request for information on CODA. Dave Mitchelson is the
    creator of the CODA system. The attached note gives you current
    information on his present location.

    In 1990, I ran a Mini-Symposium on Image-Based Motion Measurement and
    Dave wrote a paper describing his system. He has also published several
    other papers on the system. If you can't get through to Dave at the
    attached address, send me a note. I can probably find him through other
    means.

    Bob,

    CODAS is made by DATAQ Instruments in Dayton Ohio. The president of the
    company is Roger Lockhardt. CODAS is a data acquisition system which also
    lets you view the signal in real time before and as you collect. I used
    several of their products in my previous job at University of Maryland,
    College Park, MD. Contact Sally Phillips or Jane Clark, current
    faculty at Maryland, for more info on the systems they use.

    Bob Redd,

    With regard to you query about the CODAS system, you might try contacting
    Dudley Childress at the Northwester University Medical School's
    Rehabilitation
    Engineering Program. I believe that his group uses this system.

    Good Luck,

    Dear Dan,

    You may be confusing two different products here.

    CODAS is a software package for analog data acquisition. It
    essentially emulates a strip chart recorder. Data can be saved
    to files, and there supposedly is some kind of programming
    language for real-time data processing.

    CODA (Cartesian Optoelectronic Digital Anthropometer) is a
    kinematic analysis system which was produced by David Mitchelson
    in Loughborough, England. His original company went bankrupt in
    1987, but he is still trying to get a new company going again (I
    heard). I have spent a lot of time with one of the original CODA
    machines. Our technicians modified the machine because the
    original version was not reliable. It now works with wired
    markers (photodiodes) instead of reflective markers. The
    accuracy is superb (0.2 mm in a 4 m field of view at 300 Hz
    sampling rate).

    Dan,
    There is a system called CODA that is a optical data acquisition system
    similar to the Opto Track system. It was developed at Loughborough Uni.,
    U.K..
    Fred Yeadon is on this list and would give you more details of CODA.

    Subject: CODAS

    Some years ago we bought a CODAS data acquisition board for a PC/AT
    etc. I wonder if that is the same thing you are referring too. It
    came with software for scrolling data across the screen much like a chart
    recorder looks. If you wisj I can look up the manufacturer for you
    when I am at work.

    Dear Bob,

    I think you must mean the CODA system, developed at Loughborough University
    in England. To my knowledge, the only person of note using the system
    nowadays (and he uses it a lot, and is proud of it!) is Dr. Dudley
    Childress at North Western, e-mail d-childress@nwu.edu.

    Best wishes,
    Chris

    Subject: Re: CODAS System

    Bob, I believe the company that manufactures or at least distributes the
    CODAS system is: DataQ Instruments Inc.
    150 Springside Dr. Suite B220
    Akron OH, 44333-2473
    Phone#: (216) 668-1444.

    I hope this is the CODAS system you are looking for. Doug Keen.
