Regarding the Views Expressed
• Per IEEE-SA Standards Board Operations Manual,
J
January
2005:
2005
“At lectures, symposia, seminars, or educational
courses, an individual presenting information on IEEE
standards
t d d shall
h ll make
k it clear
l
th
thatt hi
his or h
her views
i
should be considered the personal views of that
individual rather than the formal position, explanation,
or interpretation of the IEEE
IEEE.”
• The views I am expressing on IEEE standards and
related products should NOT be considered the formal
position explanation
