Abstract: A modular floor tile comprising a substrate having a first land with a support surface and first and second perimeter portions each defining a second land with a surface recessed relative to the support surface, the first and second perimeter portions each defining spaced-apart T-lugs and alternating T-recesses, the T-lugs defining extending abutments and notches, whereby two tiles join together by the T-recesses of a first tile receiving respective T-lugs of a second tile, with each notch receiving a respective one of the abutments and the contacting edges thereof resist separation of adjacent joined tiles during use of the mat.

Abstract: A modular floor tile comprising a base substrate and top layer having a first land with a support surface and first and second perimeter portions each defining a second land with a surface recessed relative to the support surface, the first perimeter portion defining a recess and the opposing second perimeter portion defining a lug, whereby two tiles join together by the recess receiving a lug of a second tile, and the support surface supporting footwear remote from the second land to avoid scuffing against the joined lug and recess so the top layer is not delaminated from the base substrate.

Abstract: A computer-implemented method, system, and program product for training and/or evaluating a member of a football team with regard to the actions that are required for his or her position on the field is provided. Specifically, under the present invention, a member of a football team, referred to as a user, may select a position from a list of positions on a football team. The user is provided with a playbook that indicates the actions that the user is to take for each play in the playbook. After, while, or without accessing the playbook, execution of a computerized football game is started; a play from the playbook is selected; and the selected play is executed by the game. Before and/or during the execution of the play, the user provides one or more inputs to the game that correspond to the action(s) the user believes are required of him/her based on the selected play. The input(s) are used by the game to provide feedback that indicates how well the required actions were performed by the user.
