Abstract: Embodiments relate to customizing contents displayed at a sink device by converting received contents from a source device. The source device provides, to the sink device, the contents and display information of the source device. The display information of the source device may indicate spatial arrangements (e.g., locations and sizes) of the contents in the source device. The sink device may map sub-display regions of the source device to sub-display regions of the sink device. Moreover, the sink device generates output images for display in sub-display regions of the sink device according to the mapping. By mapping display regions at the sink device, images can be displayed in different arrangements at the sink device without the source device having any information on the configuration of sub-display regions of the sink device.

Abstract: A bolster for a railway car truck having an obstacle-free cavity located below a center plate so as to more readily accommodate truck linkage members, brake apparatus and other associated mechanical components. The obstacle-free cavity is defined by a top and a bottom member, sidewalls each having an elliptical opening therein and two spaced vertically inclined lateral ribs which distribute the weight of a body of the car between the top and bottom members.

Abstract: There is provided an articulated four wheel truck for a railway freight car and the like, having independently rotatable wheels mounted at opposite ends of longitudinally spaced apart axle bolsters. A span bolster connects and mounts the axle bolsters for yawing movement about a vertical axis relative to the span bolster.
