Abstract: An electronic controller (16) controls the operation of an electrochemical oxygen generating system (14) producing a desired gas. The product gas is fed to a storage unit (12) or a regulator (28) and pulsing valve (28) controlling the gas flow to a user. A two-stage system (180) combines a low pressure 100 and a high pressure (150) gas generating subsystems. The low pressure subsystem (100) uses IMAT's (106) to pump oxygen from ambient air to generate a low-pressure. The high pressure subsystem (150) uses IMAT's (160) to pump oxygen to high-pressure oxygen storage devices (194).

Abstract: An independent rear suspension for a motor vehicle chassis includes a pair of independent rear corner modules. Each rear corner module includes a generally-longitudinally-extending leaf spring whose forward end is adapted to be pivotally mounted to the vehicle chassis at a first forward attachment point, and whose rearward end is nonrotationally-coupled to a knuckle, such that the leaf spring operates as a trailing arm to longitudinally position the knuckle relative to the chassis. A shackle adapted to be pivotally mounted on the chassis at a second forward attachment point includes an eye that encompasses a portion of the spring intermediate the first and second end of the spring. The shackle permits a predetermined, nonzero range of relative longitudinal, transverse, and torsional movement of the intermediate portion of the leaf spring while otherwise transferring vertical loads from the intermediate portion of the spring to the chassis.
