Abstract: A system for providing a combined water and fire display is provided. More specifically, a decorative display comprises a dynamic water and fire display device where fuel/air, water, and fire are integrated. The decorative display provides for unique aesthetic qualities and an appearance wherein flames are positioned at or near the surface of a volume of water. In various embodiments, the decorative display further comprises various safety features including the ability to detect and self-regulate conditions such as the existence and/or absence of a pilot flame, an adequate amount of water, and the temperature of various portions of the system. The decorative display further contemplates the ability to operate without one or more disclosed features, such as when only a water display or only a fire display is desired.

Abstract: Snowboards with various edge structures are disclosed herein. A portion of the edge of the snowboard may be formed by a hardened or metal edge. A remaining portion of the edge defined by an absence of the hardened or metal edge forms a grind edge. The disclosed invention provides a snowboard that has only partial metal or hardened edges along its perimeter to allow the rider to slide or grind on a rail without worry of catching a hardened or metal edge on the rail, or damaging the hardened or metal edge during the grinding activity. Embodiments of the invention also relate to edge structures of snowboards that allow for easy repair of those edge structures.

Abstract: A ski device such as a snow board is disclosed which has a tip protector embedded into the upper surface of each of the tip portions of the board. The tip protector may be incorporated into regular ski tips or mono-ski tips as well as on snow boards. The tip protector is a generally flat curved strip of ductile sheet material bonded to a portion of the upper surface of the rounded tip portion adjacent to and aligned with the edge of the device.
