  • Patent number: 10988149
    Abstract: An energy absorption device absorbs energy that is released upon impact between two objects in relative motion. An exceptional load applied to any of the two objects results in acceleration of one object relative to the other object. The acceleration energy is absorbed by deformation of an element or elements that are put under stress from the objects upon impact. The process of deformation includes a controlled diameter reduction during a forced elongation of a semi-solid or solid deformation bolt made from a cold-formed material in the direction of force generated from the acceleration.

  • Patent number: 10974737
    Abstract: A transportation system includes a first support tower, a second support tower, a suspension cable extending between the first and second support towers, and a tube defining an interior channel extending between the first and second support towers. A vehicle is configured to travel through the interior channel. A tension support member has a first end coupled to the suspension cable and a second end coupled to the first tube through an actuator. The tension support member exerts tension force to upwardly pull the first tube towards the suspension cable. The actuator adjusts the tension force when the vehicle travels through the interior channel under the tension support member to reduce deflection of the tube.

  • Patent number: 10913358
    Abstract: A pantograph remote control circuit for an unmanned metro train includes a startup circuit of an auxiliary inverter emergency start relay, a control circuit of an auxiliary inverter energized relay, and a startup circuit of a pantograph raising relay. A first normally-open contact pair of the pantograph raising relay is serially connected to a pantograph raising electromagnetic valve and then connected to an output terminal of a battery. At the meantime, the bootstrap is remotely controlled by the internal ATC wake-up module when the power supply is fed by the battery, and there is no need for the driver to operate on the spot, thereby saving time for the driver from operations and reducing the potential misoperation of the driver.

  • Patent number: 10899373
    Abstract: A safety method for a railway network that is divided into section segments by way of section elements and which can be traveled by vehicles in accordance with data from a section atlas. The vehicles request steps for allocation as a track element from selected section elements. Each of the selected section elements autonomously allocates itself as a track element under specified conditions for each requesting vehicle. In order to be able to inform the vehicle or the vehicle operators thereof about changed section characteristics better and more quickly, for the section elements, the vehicles store manually entered and/or manually released dynamic driving operation data as a dynamic component of the section atlas in parts related to the section elements.

  • Patent number: 10889194
    Abstract: During travel of the electric vehicle, the charging arm is extended in the vehicle width direction, a positive electrode overhead line of the power supply device and a positive electrode power reception unit of the charging arm are brought into contact at the same time that a negative electrode overhead line of the power supply device and a negative electrode power reception unit of the charging arm are brought into contact, and a power storage device for driving the electric vehicle is charged. A charging head that is the tip section of the charging arm is held within a V-shaped groove to which the positive electrode overhead line and the negative electrode overhead line are attached, thereby minimizing the loss of contact even if the charging arm shakes in the vertical direction as a result of the condition of the road surface, brake operation, or the like.
