Development of Intelligent Automatic Pressure Release Seat (IAPRS)
IAPRS is a pneumatic system, consisting of four major components:
I: Seat cushion
II: Lumbar-sacral support
III: Pelvic stabilizer
IV:Trunk support
|
Inflation and deflation of all air bladders are realized by a single air compressor and a set of air valves.
A microprocessor is programmed to regulate the configuration of IAPRS, based on feedback from multiple sensors, e.g. the potentiometer for BPS tilting angle, an array of contact sensors on seat, and air pressure sensors inside the bladders.

* Every design of the IAPRS system and its functional components is patent pending.
