Abstract: A gladhand is disclosed. The gladhand, for example, may include a gladhand body having a central axis and a substantially flat gladhand surface and a tongue that extends from the gladhand body and substantially perpendicular relative to the central axis. The gladhand, for example, may also include a concave pocket that extends from gladhand surface. The gladhand, for example, may also include a piston chamber within the gladhand body that extends substantially along the central axis and forming a piston aperture within the gladhand surface and a piston disposed within the piston chamber that actuates at least partially into and out of the piston chamber through the piston aperture along the central axis.

Abstract: Some embodiments include an autonomous yard truck that includes a speed control mechanism; a steering system; a geolocation sensor; a plurality of sensors; a fifth wheel coupling; a robotic arm disposed on the deck; an air hose with a first hose connector; a transceiver; and a controller. The controller may identify a first trailer hose connector location on a specific trailer; determine the location of a first hose connector on an autonomous yard truck; engages the first hose connector with a robotic arm; move the first hose connector from the first hose connector location to the first trailer hose connector location on the specific trailer with the robotic arm; connect the first hose connector with the first trailer hose connector; disengage the first hose connector from the robotic arm; and/or test the connection between the connection between the first hose connector and the first trailer hose connector.

Abstract: A locomotion system for use in an all terrain vehicle. The system is configured to enable emulation of one or more of three modes of propulsion, including wheeled propulsion, walking propulsion and track propulsion. The system includes multiple selectively rotatable bogies having terrain-engaging elements that are capable of independent rotation with respect to the vehicle and the bogies.
