Abstract: A flow generator 21 for a respiratory therapy system configured to deliver a breathable gas flow to a patient comprises a housing 27 comprising an inlet 28 and an outlet 25 and a gas flow path between the inlet 28 and outlet 25. An impeller is mounted within the housing 27 for rotation about an axis, the impeller configured to be rotationally driven by a motor to provide a gas flow along the gas flow path. Various embodiments are disclosed in which the flow generator 21 further comprises a sensor 23 mounted in the housing 27 in the gas flow path and configured to detect a property of the gas flow. The sensor 23 may be mounted in the outlet 25 so as to project into the gas flow path. Flow generator may comprise an axial inlet 28 and a tangential outlet 25. In another embodiment the sensor 23 may be mounted in the inlet 28.

Abstract: A control system for controlling an exoskeleton worn by a user and having one or more actuators associated with various body members of the exoskeleton each corresponding to a body part of the user. The control system comprises a user interface for receiving input data indicative of a desired movement sequence, a memory component for storing pre-programmed movement data indicative of one or more sequential instructions required to effect the movement sequence, each instruction being associated with relative actuator movements for performing the instruction, and an actuator controller for moving the one or more actuators according to the relative actuator movements for each instruction. The control system also comprises a terrain sub-system for adjusting the actuator movements upon detection of a change in terrain slope and a balance control sub-system for periodically adjusting the balance of the exoskeleton during relative movement of the one or more actuators.

Abstract: Monoblock engine/air compressor combinations, particularly those providing high pressure gas, experience problems in lubricating the piston pins connecting the compressor piston assemblies to the engine connecting rods. To alleviate this problem, additional weight is added to the compressor piston assemblies to force a load reversal at a determinable point in the piston cycle just after top dead center, thereby facilitating lubrication of the piston pins. An equation is disclosed for calculating the weight of the compressor piston as a function of the compressor gas pressure, geometry of the rotating components and engine speed. In another aspect of the invention, weight is added to the engine flywheel to balance an unbalanced compressor piston after the additional weight has been added.
