Abstract: An apparatus for sequentially observing player positions in predetermined game plays includes a player position matrix in the form of a playing field including a plurality of L.E.D. indicators for designating various player and ball positions. A memory includes a plurality of play sequences each comprising a plurality of player positions. A keyboard control enables selection of one of the play sequences so that the changing positions of the players and ball will be visibly and sequentially imposed on the matrix through the memory to visibly display the progressive development of a play to its conclusion. The method comprises actuating the keyboard control to select one of the play sequences and to visibly and sequentially display the changing positions of the players and ball on the playing field matrix.

Abstract: A window regulator for moving a window pane through the window opening of a vehicle door includes a single eccentric arm pivotally mounted away from its ends within the door.
