Abstract: Embodiments of putter-type golf club head comprising a striking surface capable of achieving consistent ball speeds across the striking surface to account for various ball impact locations are described herein. The striking surface has at least two materials that differ in concentration away from the geometric center of the striking surface to provide this consistency. Consistent (or uniform) ball speed is achieved throughout the striking surface as the portion of the golf ball that contacts the striking surface interacts with at least two materials having a differing material characteristic.

Abstract: A device for assisting the development of an infant's visual acuity and for transferring the mother's scent to an infantile environment. Smooth and supple fabric contacts an area of the mother's body for absorbing a portion of the mother's scent and is thereafter transferred and located in proximity with the infantile environment for venting the transferred scent about the infantile environment. Due to the device's contrasting colors, the training of the infant's visual acuity can be enhanced.
