Abstract: A wearable life support system integrates an antigravity compensation apparatus for providing counter-pressures on the human body in response to antigravity conditions with an environmental defense apparatus for providing operational conditions to a human within the life support system. A filtration apparatus removes harmful conditions from breathable gas provided to a human within the system. A temperature control apparatus maintains operational conditions to a human within system. A vision maintenance and protection apparatus is kept clear through use of a demisting apparatus that prevents visual distortion of a visor covering the human visual field. The Demisting apparatus is integratable with a wearable life support system that provides environmental defense and/or antigravity compensation to the human user. A portable environmental apparatus provides ground and back-up life sustaining conditions to a human within wearable life support systems.

Abstract: A new extended coverage anti-G suit combines a new continuous lower body pressure bladder with a nonextensible outer covering. The continuous lower body pressure bladder includes an abdominal bladder section and a pair of wrap-around leg bladder sections. Each leg bladder sections overlaps slightly at the inseam. A trouser-shaped nonextensible outer covering covers the pressure bladder and restrains its expansion when the pressure bladder is inflated. A pair of pressure socks worn between regular socks and boots interconnects with the pressure bladder.
