Abstract:
System for autonomously transporting people and/or goods. The system includes at least one wheel, a chassis that supports a payload for transporting at least one of people or goods, and at least one electric motor coupled to the at least one wheel. The at least one electric motor is one of chassis mounted or at least one wheel mounted. The system also includes a battery to power the at least one electric motor.
Abstract:
A tubular structure including an outer tube an inner tube arranged within the outer tube and at least one chamber formed between the outer tube and the inner tube. The tubular structure additionally includes at least one self-healing material arranged in the chamber, wherein the self-healing material is configured to solidify and/or expand upon contact with a reacting material.
Abstract:
A tunnel system includes at least two adjacent tunnel lining systems and a sealing system. Moreover, the tunnel lining systems can include plural tunnel lining segments.
Abstract:
A segmental tube section structure having a length and a circumference, the segmental tube section structure including a plurality of tube segments extending the length in a longitudinal direction of the segmental tube section structure and extending in a circumferential direction of the segmental tube section structure, wherein each tube segment of the plurality of tube segments extends in the circumferential direction to span an equal arc of the circumference of the segmental tube section, and wherein each of the plurality of tube segments are connected to adjacent tube segments of the plurality of tube segments in the circumferential direction to form the segmental tube section structure.
Abstract:
A testing apparatus includes a chamber, having an interior maintained at a predetermined pressure, a rotor rotatably disposed within the interior of the chamber, and a sensor disposed within the interior of the chamber. When the rotor rotates, the at least one sensor measures a testing characteristic of an object disposed within the interior of the chamber as the object interacts with the rotating rotor. A method includes setting a predetermined pressure of a chamber, rotating a rotor, and maintaining a gap between a surface of an object to be tested and a surface of the rotor by adjusting, with an actuator, the object to be tested or the rotor based upon a change, as measured by a laser, in the dimension of the object to be tested or the rotor.
Abstract:
A corrosion-resistant cover system, having a corrosion-resistant cover structured and configured to be arrangeable around an object having one or more metallic surfaces that are susceptible to corrosion. The corrosion-resistant cover is operable to provide increased corrosion resistance to the object by preventing contact between the one or more metallic surfaces and ambient conditions exterior to the corrosion-resistant cover.
Abstract:
Vehicle guidance system that includes a first guidance bogie selectively positionable in a first position for travel and a second position for direction change and a second guidance bogie selectively positionable in a third position for travel and a fourth position for direction change. At a common crossing, one of: the first guidance bogie is selectively positioned into the second position, or the second guidance bogie is selectively positioned into the fourth position.
Abstract:
Method and system for autonomously transporting people and/or goods. The method includes requesting conveyance of a payload from a designated area to a destination, autonomously moving at least one module to the designated area, loading the at least one module with a payload within the designated area, and, via the at least one module, autonomously transporting the payload to the destination.
Abstract:
A transport vehicle for traveling in a low-pressure environment structure is provided. The transport vehicle may include a deployable decelerator provided on the transport vehicle and configured to deploy from the transport vehicle to decrease a distance between the transport vehicle and the low-pressure environment structure. When the decelerator is deployed the decelerator is configured to increase drag forces opposing a direction of motion of the transport vehicle and decelerate the transport vehicle.
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.
