PHOSPHOINOSITIDE 3-KINASE ASSAYS IN CANCER DIAGNOSIS

Not Available A high efficiency and precision control pneumatic/mechanical actuator which converts chemical to mechanical energy will extend human performance and provide advantages in reducing system weight and bulk. Quoin will analyze the concept of an actuator based on a central air compressor and distributed hot gas actuators - each with a small pulse burner. A single unit will be built in Phase I. The central power unit provides up to 1,500 watts of output in the form of compressed gas. This gas is distributed to feed control valves, which then feed micro burners. These burners increase the energy of the gas by a factor of 7-10 as they introduce and burn hydrocarbon fuels. The high pressure, high temperature gas drives a reversing turbine that, combined with a reduction gear set and a ball-screw, forms the high-energy dense actuator. This provides an exoskeleton with a highly responsive, small actuator and power supply package with extremely high power density. Molded ceramic components create high temperaturetolerance with very low production costs. The practical and economical potential of an exoskeleton powered by a chemo-mechanical actuator is far-reaching for both military and civilian commerce and industry.
