Abstract: This invention relates to a batting trainer consisting of a ball launching apparatus with a ball propulsion mechanism for propelling a ball and a training ball much lighter and smaller than a regulation baseball or softball that can train an inexperienced batter to practice hand-eye coordination on a smaller flying target for improved swing precision. The said ball launching apparatus can be in a form of a flying-ball launching toy gun, with said training ball being made of soft cellular plastic foam and having a circumference smaller than 60 mm and a weight lighter than 30 g. It will be safe for an inexperienced player to practice his/her swing with said batting trainer in a limited open space such as the backyard.

Abstract: This invention relates to an infrared (IR) fuel activation device consisting of an infrared emitting body composed of selective metal oxides comprising at least 0.2 wt. % (weight percent) of cobalt oxide (CoO) that provides enhanced combustion of fuels in internal combustion engines, resulting in better engine performance with increased power, improved fuel economy, and reduced emissions.

Abstract: This invention relates to a piece of adhesive sticker that can be attached to a coaster or a beverage serving means for energizing alcoholic or non-alcoholic beverages at or before serving comprising a far infrared ray emitting material that can activate molecular and intermolecular bonds of water and the dissolved substances in the beverage with far infrared emissions, thereby their effects are evident in improved tastes of the beverages.
