How CYPRES works
The processing unit contains a factory-programmed microprocessor that is capable
of real-time calculations of the jumper's altitude and rate of descent on the basis of
barometric pressure.
By monitoring this data, certain criteria are generated from which conclusions are
drawn. Should the conclusion be that the jumper is in a dangerous situation (i.e. still in
freefall at a low altitude) the processing unit triggers the release unit to open the
reserve container.
The release unit or Emergency Opening System (EOS) for the reserve container is
completely independent of the rig's system, because it does not pull the ripcord pin
out of the closing loop but actually cuts the loop inside the reserve container to release
the pilot chute. This method is exclusive to CYPRES.
CYPRES' opening system has these advantages:
•
The reserve container can be opened two different ways. One method is used
by the jumper – pulling the reserve release handle; the other method is used by
CYPRES when it cuts the closing loop.
•
Mechanical components are reduced to a single movable bolt in the release unit.
Processing and control functions are electronic-based.
•
The opening system is situated inside the reserve container where it will not be
exposed to external battering or other adverse influences
•
The system is unobtrusive and can be installed so that it is undetectable from the
outside.
