An apparatus and method for determining the kinematic characteristics of a golf club head are disclosed. The apparatus includes at least one piezoelectric component selectively positioned within or upon a club head. The piezoelectric component is preferably positioned to the rear of the center of gravity, and near the midpoint of the face of the club head. During a golf club swing, the piezoelectric component determines the acceleration and deceleration of the golf club head. When the club head impacts an object such as a golf ball, the piezoelectric component is also operable to determine the velocity of the club head. It may also be desirable for the piezoelectric component to determine the magnitude of vibration during impact. In this manner, the piezoelectric component may function determine the efficiency of a golf club swing.

An engine hood for motor vehicles possesses a deformable head impact zone for the protection of pedestrians in the event of a collision with the motor vehicle. The engine hood is composed of two or more load-bearing shells and has a flexural strength profile which is low adjacent the edges and increases continuously toward the middle of the hood. At the same time, the engine hood has a uniform mass distribution ovcr the entire surface. Consequently, irrespective of the position the engine hood, the same characteristic for the head impact is achieved everywhere. The advantageous embodiment of the engine hood provides a reinforcing panel with regularly arranged beads, at most three beads forming a junction point so as to reduce local rigidities.

A hood structure comprises an outer and an inner which form a closed cross section through spaces. The inner's cross-sectional shape is a sine curve, an nth-power-raised sine curve, or a spline curve having a corrugation length approximate to an outside head diameter. This corrugated hood structure can provide a uniform, excellent head impact resistance independently of impact positions on the hood. The corrugated hood structure also excels in tension rigidity, bending rigidity, and torsional rigidity. Accordingly, the car body hood panel structure satisfies requirements of head impact resistances for pedestrian protection and rigidity improvement such as the tension rigidity.

A golf club head with an improved face insert is disclosed herein. More specifically, the present invention discloses a golf club head wherein the face insert has a cavity near the top surface of the face insert that extends vertically downward towards the bottom surface of the face insert while terminating short of the bottom surface. The face insert having the cavity serves to remove unnecessary weight from the upper surface weight of the face insert; while the cavity that terminates short of the bottom surface yields a solid face insert near the bottom surface to preserve the structural integrity of the face insert where the golf club head impacts a golf ball. The cavity created within the face insert may be filled in with a lightweight material that helps further maintain the structural integrity of the entire face insert while still removing unnecessary weight from the face insert.
