Abstract: A system and method for tracking the flight of golf balls at driving range. The invention includes a plurality of hitting stations, a plurality of sensors, a computer, and a range surface. Each hitting station in the plurality of hitting stations includes a golf ball, a golf club, a monitor, and a sensor. At least one other sensor in the plurality of sensors is placed outside the hitting station. The flight path of the golf ball is calculated by the computer using parameters by the plurality of sensors. The method includes steps for determining whether a first sensor detected a first parameter and a second parameter, whether a second sensor detected a first and a second parameter, whether a third sensor detected a third parameter, and depicting the flight path of the golf balls using the first parameter, the second parameter, and the third parameter.

Abstract: Provided is an electric generator which is capable of being used indoors. The electric generator employs the use of a cooling system which injects water directly into the engine through a domestic water pipe. The cooling system does not require the use of a water pump, radiator, cooling fans, alternator or any associated belts. The electric generator also employs the use of an exhaust system which allows for the passage of cooled exhaust gases and water from the engine in a safe manner without having exhaust fumes enter the home and without posing a fire hazard to the home or building structure. Further advantages of the indoor electric generator are discussed herein.

Abstract: A game-play environment includes a tee box, a range surface, and a monitor. The tee box is configured to permit a player to hit a golf ball onto the range surface. The range surface has a plurality of physical markers. The monitor depicts a virtual environment that includes a plurality of virtual components. Some of the virtual components are visual cues that correspond to the physical markers. A player is able to play the game by targeting the appropriate physical marker that corresponds to the desired visual cue.

Abstract: A cardboard display case for DVDs and the like has a box-like case of folded cardboard with a plurality of shelves on three sides for displaying goods. A retractable pop-up display header extends above the top face of the case near the back. There is a hollow inside the case so that the header can be retracted within the case for shipping. When at a retail store, for example, the header is pulled up to display graphics above the top of the case. A folded cardboard member within the case has a retractable shelf supporting the header when extended above the case. The shelf is folded out of the way when the header is retracted within the case.
