Abstract: A method for manufacturing at least one transportation tube having a plurality of transportation tube sections for a high-speed transportation system. The method includes manufacturing the tube sections in-situ adjacent to an approximate path of the transportation system where the tube sections are to be positioned.

Abstract: A high-speed transportation system, the system including at least one transportation tube having at least one track, at least one capsule configured for travel through the at least one tube between stations, a propulsion system adapted to propel the at least one capsule through the tube; a levitation system adapted to levitate the capsule within the tube, and at least one tube sealer arranged along the at least one tube and configured to create an airlock in the at least one tube. In embodiments, the tube sealer may include a gate valve and/or an airbag.

Abstract: An axial compressor includes a housing and a plurality of stages arranged within the housing and along an airflow direction, each stage of the plurality of stages including a first blade assembly and a second blade assembly, wherein the first blade assembly is a rotor, each rotor being drivable independently from the rotors in the other first blade assemblies.

Abstract: A high-speed transportation system including at least one transportation tube having at least one track, at least one capsule configured for travel through the at least one tube along a travel path between stations, a propulsion system adapted to propel the at least one capsule through the tube, and a levitation system adapted to levitate the capsule within the tube. At least a portion of the travel path is arranged over or in a body of water.

Abstract: A tubular structure stability system includes at least one tube having tube sections and at least one pillar supporting the tube. A tube movement structure is also provided and configured to enable relative movement of the tube sections and/or movement of the tube relative to the at least one pillar.

Abstract: A high-speed transportation system, the system including at least one transportation tube having at least one track, at least one capsule configured for travel through the at least one tube between stations, a propulsion system for the at least one capsule; and a levitation system for levitating the capsule in the tube.

Abstract: A dynamic linear motor is controlled by determining a relative proximity of a moving rotor of the linear motor to a fixed stator segment of the linear motor using a current location of the moving rotor. A current driving characteristic of the linear motor at the current location of the moving rotor is determined. Settings for the fixed stator segment when the moving rotor reaches the fixed stator segment are identified based on the current driving characteristic. The fixed stator segment is driven based on the settings when the moving rotor reaches the fixed stator segment.

Abstract: A magnetically continuous winding includes a first coil and at least one additional coil substantially fixed in place in at least one direction with respect to a position of the first coil. A core formed by a resin is applied to the first coil and the at least one additional coil to substantially bind the first coil and the at least one additional coil.
