The present disclosure provides a socket assembly (100, 200, 300). The socket assembly (100, 200, 300) includes a socket (1) and a power supply expansion component (2). The socket (1) includes a first housing (11) and a first terminal group (13). The first terminal group (13) is disposed on the first housing (11) and electrically coupled with a power source. The power supply expansion component (2) includes a second housing (21), a second terminal group (23) and a power transmission unit (22). The second terminal group (23) is disposed on the second housing (21) and electrically coupled with the power transmission unit (22). When the first housing (11) is assembled with the second housing (21), the first terminal group (13) and the second terminal group (23) are contacted to establish electrical conduction, and the power source supplies electric energy to the power transmission unit (22) through a transmission path formed by the first terminal group (13) and the second terminal group (23).

The present disclosure provides an inductive power supply (1, 1a, 1b) and an object detection method thereof. A resonant signal is generated when the resonant capacitor (30, 30a) resonates with the power supply coil (20). A voltage detector (32) receives the resonant signal and converts it into a detection signal. A processor (4) obtains a resonant cycle of the resonant signal according to the detection signal. After the driving unit (31, 31a) drives the power supply coil (20), the resonant capacitor (30, 30a) resonates with the power supply coil (20), and a timer of the processor (4) starts timing. When the resonant cycle exceeds a cycle threshold, the timer stops timing. The processor (4) calculates and obtains a measurement of time length according to an interval between the start time and the stop time of the timer. When the measurement of time length is less than a preset time length, the processor (4) determines that there is an object within the power transmission range of the power supply module (2).

A system for improved intermodal freight transportation is described herein. Improved carriages and support trusses are provided that beneficially move the load-bearing structure to interconnected support trusses forming a top-end spine of the train with freight containers equipped with wheels hanging underneath. Upon entering a terminal, the floor adjacent to the rails may be configured to gradually rise until the container's wheels are supporting the container's weight. When properly aligned with a container exchange station, the container's connections to the train may be configured to release the container from the train, and the container's wheels may be configured to pivot, allowing the container to be rolled to the side of the train and replaced by another. This may allow the container to be replaced without having to lift the container or disconnect any of the rolling stock components.
