Abstract: A system includes a source that provides air, a first compressor stage that receives the air from the source and is configured to compress the air to a first pressure, and a second compressor stage that receives the air from the first compressor stage and is configured to compress the air to a second pressure. The system also includes a first component, a second component, valves that control flow of the air, and a controller that is configured to control the valves according to a first control mode, in which the air is supplied to the first component by the first compressor stage, and a second control mode, in which the air is supplied to the second component by the second compressor stage.

Abstract: A motion control system that can detect a change in a an operating characteristic and send a stabilizing command to an actuator system based on the change is described. A motion control component in the system includes a first component with an electropermanent magnet having a coil, differing first and second permanent magnet materials, and differing first and second states. The motion control component includes a second component configured to magnetically interact with the first component to define a damping characteristic that affects motion between the first component and the second component and a controller configured to supply a current pulse to the electropermanent magnet to switch the electropermanent magnet between the first and second states. The electropermanent magnet retains the respective first or second state after cessation of the current pulse.

Abstract: A system includes a compressor that receives air from a source and is configured to supply compressed air, a first system that is configured to receive the compressed air, and a second system that is configured to receive the compressed air. In first control mode, a first control valve blocks flow of compressed air to the first system and a second control valve allows flow of compressed air from to the second system. In a second control mode, the second control valve allows flow of the compressed air from the second system to a dryer along, and the first control valve allows flow of the compressed air from the dryer to the first system.
