Abstract: A seat identification system for passengers in a cabin of a commercial airliner. Four sign components, identified as the aisle, mile, row and seat components, are arranged and positioned throughout the airplane in a configuration that allows the passengers to receive information about their seats when needed. The aisle signage markers direct the passengers down the appropriate aisle which leads to their seat. The interval row markers or mile markers provide a general location of the particular row in the aircraft for the passenger's seats. The individual row markers are preferably located in the passenger service unit modules and in viewing channels in order to allow the markers to be visible from the aisle. The seat markers are located preferably on the headrest on each seat and are the final vindication that the passenger is in the correct seat.

Abstract: A game board for use in a game wherein the board is caused to tilt about a centrally located support by moving playing pieces on the board in game play, the board being composed of a relatively thin high impact styrene plastic material. The board has a horizontal coplanar surface with regularly spaced depressions of uniform cylindrical configuration for receiving the playing pieces. The bottoms of the depressions are coplanar and their areas total slightly more than one-half of the total horizontal surface of the board obtained by measuring its length times its width (less the supporting projections). The depressions extend downwardly substantially below the supporting projections, thus significantly lowering the center of gravity of individual playing pieces received in the depressions. This assists in maintaining the center of the gravity of the board and the playing pieces thereon at approximately the same level as where the projections meet the underlying supporting structure.
