DYNAMIC ENHANCEMENT OF DIALYSIS EFFICIENCY

Not Available When a parachute malfunctions, it is critical that the jumper deploy the reserve parachute quickly to ensure that the reserve canopy has adequate time to inflate and slow his descent. Minimum container opening altitudes above the ground for recreational skydivers are at least 2000 feet AGL, which affords the jumper enough time to determine his canopy status and activate the reserve if necessary. Skydiving students are required to use Automatic Activation Devices (AADs), however experienced skydivers do not use AADs because they are prohibitively expensive. Military combat and training jumps are often done from 500 feet AGL and there is very little time to determine whether a malfunction exists. Consequently, the use of an AAD is highly recommended since the jumpers reaction time may be inadequate to ensure a safe landing. There are commercially available AADs that can function in a military setting, however their use is cost prohibitive in a mass tactical setting. We propose to develop a cost effective AAD suitable for low altitude jumps that utilizes accelerometers and pressure sensors to determine the jumpers rate of descent, altitude and acceleration. By utilizing high performance low cost sensors, a reasonably priced device can be manufactured for military use. BENEFITS: The currently available AADs are very expensive: the Cypress 1-pin Expert sells for $1 175, the Astra l-pin Expert sells for $950 and the FXC 12000 sells for $875. We plan to offer a comparable d
