Abstract: A system includes a transmitter circuit and a receiver circuit that are coupled together through transmission lines. The transmitter circuit generates an early timing signal, a nominal timing signal, and a late timing signal. A multiplexer circuit selects between the early and the late timing signals based on a data signal to generate an encoded output signal that encodes the data signal. The nominal timing signal and the encoded output signal are transmitted through the transmission lines to the receiver circuit. The receiver circuit samples the encoded output signal in response to the nominal timing signal to generate even and odd sampled data signals. Complementary timing signals can be transmitted through transmission lines on opposite sides of the encoded output signal to provide crosstalk cancellation.

Abstract: Tiles (7) having significant depth are placed on a gameboard (1) having projections (2) on its upper surface. The protrusions (2) engage recesses (8) formed on the corners of the tiles (7) in order to locate the tiles (7) in position on the game board (1). The recesses (8) may extend for only part of the depth of the tiles (7) so that they are not visible from the top of the tiles (7), thereby affording visual continuity between the (tiles 7). The protrusions (2) may engage the recesses (8) as a friction fit, to hold the tiles (7) firmly in place. Alternatively, they may engage the recesses (8) as a loose fit, thereby to afford location of the tiles (7) while allowing their easy removal from the game board (1).
