Abstract: This present invention is a golf club head that has a concave shaped crown directly downwardly from behind the striking face toward the read edge of the club head. The rearwardly directed side portions of the club head include rudder elements extending along both sides at the same height as the club face, much like the rudder of an airplane. The rudders are connected across the respective top rear portions of the side elements of the club head, with an optional aero stabilizer that is roughly one quarter of the front to rear dimension of the club head. One or more removable fins can be inserted into the channel shaped slots between the side rudders to act as additional rudders for additional influence to the club head. The rear of the club head is open between the rudders and below the optional stabilizer for directing the flow of air.

Abstract: A method and apparatus for guiding a vehicle into an optimal position within a parking space. A first linear ray of light is projected along the centerline of a parking space. A second linear ray of light is projected at an angle to and intersecting the first linear ray within the parking space. The first linear ray of light guides the driver while moving into and through the space when the driver aligns an indicator on the vehicle with the first linear ray of light. As the driver nears the optimal position, the second linear ray of light will move towards the indicator. When the indicator coincides with the intersection of the first and second linear rays of light, the vehicle is in the optimal position.

Abstract: A method and system for guiding a vehicle through a tunnel or other space. A linear beam of light is projected along a certain path through the space. As the vehicle travels into the space, the linear beam is shined upon the vehicle. Visually aligning an indicator on the vehicle with the linear beam of light indicates to the driver that the vehicle is traveling directly down the center of the path. The alignment occurs by the driver making manual adjustments of the vehicle's direction by turning wheels of the vehicle.
