Abstract: A system for broadcasting a sporting event related to one or more moving objects (such as race cars) includes a plurality of stations disposed along the objects' trajectory. Each station includes an automated camera unit. A central command post receives the location of each object and sends commands to the respective cameras to cover the objects as they move. The signals from the cameras is then mixed automatically at the central control post and used to generate several video signals. The programs are transmitted directly to broadcasters, or are distributed via the Internet.

Abstract: A shoe of the inflatable type having a midsole supporting member with a number of hollow downwardly extending support posts intercommunicated by channels recessed in the upper surface of the member. The upper surface is covered with a layer of natural rubber, to form enclosed air spaces with the hollows of the posts, and (in cooperation with the channels) conduits providing restricted passageways interconnecting the hollows of the posts. A valve extends from the exterior surface of the heel of the shoe to permit inflation by injection of air into the posts and conduits.
