Abstract: Aerodynamically augmented hockey puck design uses the dynamics of airflow around a moving body to assist in overcoming the unwanted forces of friction that inherently exist between two opposing surfaces and may be used on either an ice or other non-ice playing surface. The puck influences airflow through a symmetric ducted venting system designed to duct or vent air from multiple inlets positioned above a boundary layer to opposing outlets. The ducted venting system reduces pressure differentials between the inlet and outlet of the air channel. Circular center pocket cavities of the upper and lower planar surfaces of the hockey puck are vented to the opposite edge of the outer cylindrical surface of the hockey puck. Elliptical air channels extend radially from the circular center pocket cavity and are symmetrically placed and positioned above the boundary layer around the outer cylindrical surface of the puck.

Abstract: An automated goalkeeper assembly includes a track having a length; a goalie structure; and a base that supports the goalie structure on top of the track. The base has wheels and a motor cooperating with at least one of the wheels for moving the goalie structure along the length of the track. A player, for example, a hockey player or a soccer player, can practice scoring goals against the goalie structure. The goalie structure is preferably inflatable, and the track is preferably constructed from a plurality of track sections. The track preferably has grooves and the base preferably has flanges that cooperate with the grooves to keep the base secured in the track when the player bumps into the goalie structure. All of the components of the goalkeeper assembly can be provided as a kit that can be assembled and disassembled as desired.
