Abstract: A brake system is disclosed, including a rotor rigidly connected to a shaft configured to rotate about a central axis. The rotor has a first side opposite from a second side, and the brake system includes a first stator structure on the first side of the rotor and a second stator structure on the second side of the rotor. The brake system further includes a first wobble plate between the first side of the rotor and the first stator structure and a second wobble plate between the second side of the rotor and the second stator structure. Each of the first and second wobble plates is configured to nutate when the first and second stator structures decrease rotation rate compared to the rotation rate of the rotor.

Abstract: A railway car for traveling within a switch of a railway track is disclosed. The railway car includes a body portion for containing goods and a truck portion that is a framework for carrying a plurality of wheels of the railway car. The truck portion is connected to the body portion and is rotatable about an axis of rotation relative to the body portion. The railway car also includes a rotational joint defining the axis of rotation which the truck portion is rotatable about. The rotational joint rotatably connects the truck portion to the body portion of the railway car.

Abstract: A passive switch for a railway track is disclosed. A railway car is moveable along the railway track in a facing direction. The passive switch includes a first track section and a second track section. The first track section includes a first main track, a first diverging track, and a first guard rail. The first guard rail is shaped to guide a first wheel of the railway car from the first main track onto the first diverging track as the first wheel travels in the facing direction within the passive switch. The second track section includes a second main track and a second diverging track. The second main track is shaped to guide a second wheel of the railway car from the second main track onto the second diverging track.

Abstract: A launch device may be prepared for launch. The launch device may be assembled in a horizontal position on a mobile device. A lifting device attached to the mobile device may be coupled to the launch device. The launch device may be moved to a launch site using the mobile device. The launch device may be moved to a vertical position at the launch site using the lifting device. The launch device may be launched.

Abstract: An apparatus comprising a housing having an opening, a connector unit, a moveable door, and a biasing system. The connector unit is located inside the housing. The connector unit is capable of providing an electrical connection to a complementary connector unit. The moveable door is capable of being moved into an open position and a closed position, wherein the closed position covers the opening. The biasing system is capable of aligning the connector unit with the complementary connector unit and causing the connector unit to engage the complimentary connector unit.
