Meeting:
Andy Whitehouse of Andy's Drysuits and Undies...
Wednesday,
August 28, 2002
7:30pm at the Virginia Dance Center
9855 Fairview Ave, Manassas, VA 20110
Chairs will be in short supply (as in none!) so if you don't
want to sit on the floor or stand, bring a folding chair or two.
This months
meeting will focus on drysuits & drysuit undergarments. Andy
Whitehouse, a personal friend of Dave Dalton's for the past 30 years,
and the founder & owner of Andy's Drysuits and Undies will be
our guest speaker to answer all of your questions on drysuits and
undergarments.
And as an added bonus Andy has made the following offer:
Andy has developed
a new type of undergarment which he is in the process of bringing
to the market place. About all that is left is to determine sizing.
Andy has offered to give a 10% discount on an Andy's drysuit/undergarment
combination to anyone who will act as a guinea pig and try on the
new line of undergarments (please wear a bathing suit under your
clothes if you wish to participate - these meetings are "G"
rated!). Just make your best deal with the Andy's retailer of your
choice and have him/her call Andy to reduce your price an additional
10%. What a deal! And in addition you will be able to tell your
dive buddies that you were "instrumental" in the development
of the product! ...

Dr. Bruce Wienke is the developer of the dive algorithm known as
Reduced Gradient Bubble Model (RGBM), which is based on the physics
of bubble formation. Wienke's research is in collaboration with
the University of Rochester, the University of Trondheim, Norway,
the University of Wisconsin, the National Aeronautics and Space
Administration and the University of Hawaii.
The benefits
of the RGBM are that divers can go deeper, stay longer and spend
less time decompressing than with the Haldane Table. Keeping nitrogen
and helium bubbles from forming in the body is the goal of both
the Haldane Table and RGBM. The advantages of RGBM stem from its
use of mixed gases, the most common trimix, heliox, and nitrox,
and a different approach to determining the depth and timing of
decompression stops upon ascent based on the properties of these
gases and their biophysical response to various levels of pressure.
A big part of
the reason for RGBM’s acceptance is Wienke's diving experience.
Wienke has logged more than 3,000 hours underwater as deep as 400
feet and in locations all over the world, from under the ice of
the arctic to the tropic waters of the South Pacific. Author of
five technical diving books, including "Basic Decompression
Theory and Application," and "Basic Diving Physics and
Application," Wienke credits RGBM’s success to a common
diving language.
