CYPRES
“When you can’t afford to leave anything to chance, there’s CYPRES. 100% reliability”.
The first CYPRES save was in April 1991, just three short months after the CYPRES was introduced to the skydiving market.
There are now more than 25 different CYPRES models in use that offer the ideal solution for different applications. All of the devices share the same precision and reliability.
How Cypres Works
CYPRES' simplicity is part of what makes it so brilliant. The gadget unobtrusively calculates the jumper's altitude and rate of descent in real time by sensing barometric pressure as skydivers enjoy a day of jumping. CYPRES detects a malfunction, cuts the reserve loop, and deploys the reserve parachute if a set of specified thresholds are surpassed. Although it seems straightforward, the engineering that goes into such a little gadget is a remarkable achievement.
Device Overview
The moment the CYPRES device is turned on, magic starts to happen. During the self-test, the device takes many air pressure readings and averages them to determine the ground level.
While you might need to give your altimeter a break before a leap, CYPRES looks after itself. The calibration serves as the foundation for CYPRES' recognition of the activation height and speed with respect to the ground. A factory-programmed microprocessor in the processing unit can calculate the jumper's height and rate of descent in real time using barometric pressure. To put it another way, the CYPRES knows when to cut the reserve loop at the proper height and under the proper circumstances. (high speeds, low altitude)
