Dear sEMG Users;

Noraxon U.S.A., Inc. has been requested to respond to a network
communication on Nov. 23, 1994 by Jon Fewster, a student at Oregon State
University. His comments have prompted a number of inquiries from our
clients world-wide as well as potential users fo our technology.
Initially, we were as surprised by this communication as were many of
our prestigious clients whose work has been enhanced by our technology.
However, after speaking with Dr. Gerald Smith, a professor in the
Biomechanics Laboratory at OSU, we have a better understanding as to
what may have prompted Jon's remarks, although Jon, we're told, will not
be available for consultation by the OSU faculty until after the
holidays. This being the case, it is our desire to clarify, for the
record, the circumstances that perhaps led to his observations.

As Jon correctly stated in his message, he, personally, has never used
Noraxon's sEMG equipment. We were informed that he was neither directly
nor indirectly involved in the research projects that he referenced.
His source of information came mainly from rumors circulated among other
students who may not have been familiar with the complexities of the
initial installation processes, several of which were unrelated to the
EMG instrument itself. For example, the new 486 computer pruchased by
the university was not capable of handling the A/D card, an
incompatability initially unrecognized by the manufacturer of the card.
A second inconvenience were the difficulties experienced in calibrating
another piece of laboratory equipment which the OSU staff wished to
interface with the sEMG instrument. Inadequate specifications from the
manufacturer of this equipment made the interface a difficult and more
lengthy process.

However, these situations were eventually resolved. We feel,
none-the-less, that OSU has had its share of frustrations with projects
which incorporated sEMG measurements. We recognize the neccessity of
being doubly aware of our clients needs when they embark into new areas
of research and experimentation. In times such as these, a lack of
information or timely support can impact results and reflect negatively
on all parts of the process. We also recognize that there is always room
for improvement. We will strive to do our part to minimize negative
impressions which can be so easily created in situations where our
equipment is selected for use for the first time.

Hopefully, this message will help put these circumstances in a clearer
perspective for those who have inquired. Those of you who are veterans
in the use of new technologies will more easily relate to frustrations
in complex start-up situations. We fully accept our part of the
responsibility in this and all situations in which we are selected for
significant involvement. In this instance, we feel badly that the
situation was such that undesirable impressions were formed and
reflected negatively on our personnel and products. If you have other
observations, questions or a need for additional information, we invite
you to contact us.

We sincerely wish Jon and his colleagues continued success in their
studies at OSU. We appreciate the excellent cooperation of the very
competent faculty and staff in Corvallis as well. To all of you around
the world who have knowledge of and interest in Noraxon, we send Holiday
Greetings. We will strive to satisfy your needs and opportunities even
better than before in 1995.
