I was asked to repost this here concerning my construction of the prototype
this is my last post for abit as I need to spend as much time as I can on
getting this
built  I have to post this in three parts because of its size.

I do need any doctors out  there who have experiance in cryonics to please
contact
me.  I want to make this system as effective as possible.

VPS
                                                                Vogt
Presuspension System




     What is the VPS ?

   The Vogt Presuspension System is a cooling device designed to start the
   immediate cooling of the
   brain at the moment of death -- or as near to that moment as it can be
   implemented to help
   prevent deterioration to the brain after death has occurred


     Why is this unit needed?

   The VPS is a system designed to help solve one of the issues that had
   been a serious concern:
   A lack of an advanced and compact refrigeration method. Current methods
   require a team, with the co-operation of a hospital, to transport or
   scavenge ice to cool a patient before freezing.

   A theoretic example: If a patient were to die suddenly outside the care
   of ALCOR, they would be required to fly, either with all the ice and
   cooling materials needed to minimize the damage being done to brain by
   waiting to be cooled in the hospital morgue, or scrounge them up
   locally. Even assuming that the hospital staff was diligent enough to
   administer the required procedures to keep the body cool, it would be
   between 6 to 8 hours before they arrived on the scene if the patient
   were along the east coast near or in a major city.

   There are many additional factors to consider here:  Can a hospital
   staff be expected to spend resources and time (6-8 hours) maintaining
   precise and constant cooling on a corpse?  What sort of temperature
   management would/could they supply if they did?  Will whatever support
   they DO decided to provide not to interfere with what ALCOR has to do
   when they begin suspension?

The VPS has these advantages:

The unit is very portable and contains no temperature-perishable material.
It does not require any form of gasses for cooling, using instead an
electrical method using battery assistance -- this means it would not be
barred from transport upon airlines, and could even utilize airline power
resources to maintain the patient.

Because it is an electrical means of cooling using the Peltier effect, it
can be controlled with high levels of precision, with sensors giving degree
accurate readings that will allow cooling to be maintained at as close to
freezing as safely possible.

Such a device would actually be much less intensive to administer. Although
ice is a common and everyday form of cooling, it can be laborious to
maintain and transport even on a local level.  This device will allow
cooling to be administered without such messy concerns.

     How does it work?

   The VPS  is a three-piece system that consists of the refrigeration unit
   , battery pack/powersupply, and liquid precooler.
