Abstract: A golf putting aid is disclosed that includes a level detector for measuring a slope of a golf green and for generating an electrical signal representing the measured slope, a control circuit coupled to the slope measuring sensor for receiving the electrical signal and for generating an indicator signal representing information that will aid a golfer while making a putt on the golf green, and an indicator coupled to the control circuit for receiving the indicator signal and for indicating the information represented by the indicator signal to a golfer. Preferably, the level detector measures the slope of a golf green at at least two locations and generates electrical signals representing the measured slope at each location. The control circuit then processes the electrical signals to compute an offset distance from the hole at which the golfer should aim so as to compensate for the measured slopes of the green.

Abstract: An instant replay system for a bowling scoring system is disclosed in which a video clip of a bowler's approach and deliver of a bowling ball and a video clip of the bowling ball subsequently entering a pin-fall area are filmed, compressed, and stored in a memory device, such as a hard drive. The instant replay system includes a controller for receiving user requests from a user input terminal of the bowling scoring system and for responding to such user requests by selecting a stored video clip and controlling playback of the selected video clip on a display monitor of the bowling scoring system. In this manner, a user may request that the replay video clip be played in at any selected rate, that the controller freeze the display on a specific video frame, and that the controller fast-forward or rewind the video clip. Further, the user may request the replay of any previously stored video clip by specifying the bowler, game, frame and ball of which the video clip is taken.
