Abstract: A method of presenting content to a viewer is described. The method includes: receiving a schedule of content at a client operable by the viewer, the schedule of content including a directed graph, the directed graph including a plurality of nodes, wherein each node in the plurality of nodes is connected to one or more other nodes in the plurality of nodes by one or more paths, wherein each path represents content presentable to the viewer; traversing the directed graph by following a route between nodes and along paths of the directed graph, wherein at each node the client determines a path to follow according to state information accessible by the client; and presenting content to the viewer as each path is followed.

Abstract: A roll fusing apparatus comprising a heated roll structure and a resilient backup roll cooperating with the heated roll structure to form a nip through which toner images as with the toner images contacting the heated fuser roll structure. The heated fuser roll structure comprises a rigid core and an elastomeric outer layer, the outer surface of the rigid core and the inner surface of the elastomeric layer having non-uniform cross sections which are complementary one to the other to thereby provide alternately thick and thin segments or portions of elastomeric material wherein the thick portions provide for a greater capacity of release agent material than the thin portions while the thin portions provide a minimal barrier to heat transfer from within the heated fuser structure to the external surface of the elastomeric layer.
