Abstract: An aesthetic insert adapted to be received between a wheel-bearing rail and the center rail of extant model railroad track, and in its installed position at least partially covers or hides the side of the center rail, camouflaging it and rendering it less noticeable. The installed insert superposes portions of and simulates the presence and/or appearance of a crosstie surface. The insert may be a separately installable, individual element, or a plurality of interconnected individual elements installable as a group and interconnected by one or more connecting members.

Abstract: Disclosed are a system and method of configuring processing resources for communication with one or more devices coupled to a data bus through a bridge. Resources at a processing system may be configured to communicate with the bridge as a transparent bridge or a non-transparent bridge depending on how the processing system may be implemented in a processing platform.

Abstract: A toy system including a housing, an ultraviolet light source provided in the housing; and a representative element comprising photochromatic material, the representative element being temporarily disposed in the housing, the representative element being exposed to the ultraviolet light source while in the housing, the representative element having a first state in which a first condition is visually simulated and a second state in which a second condition is visually simulated, the first and second visually simulated conditions being different from one another. One of the first and second states is achieved in response to the representative element having been within the housing and exposed to the ultraviolet light source, whereby a corresponding one of the first and second conditions is simulated by the representative element having been within the housing.
