Abstract: The Designated Hitter Pitching Training System (DH) is a silhouette figure of a batter that stands in the batter's box during bullpen sessions for baseball and fastpitch softball pitchers of all ages and skill levels. Constructed of durable polyethylene, the DH comes in three sizes: the Pro (6?2?), Varsity (5?8?) and Youth (5?2?). The DH provides a more realistic, game-like way for pitchers to practice and will improve a pitcher's ability to more consistently throw their pitches in the strike zone, as well as pitch more accurately and confidently to the inside part of the plate with the Inside Pitch Target. All of this will combine to improve game performance. The DH can also be used by pitchers and catchers as part of their practice activities such as throwing to bases, bunt defense, pitchouts, and intentional walks.

Abstract: Two stroke internal combustion engine control compensates for diagnosed cylinder misfire conditions characterized by improper combustion, during a cylinder combustion event, of an air/fuel mixture in an engine cylinder by learning a required number of cylinder combustion events to periodically be skipped to allow for removal of residual combustion elements from the cylinder following improper combustion therein, and by periodically postponing cylinder combustion over the learned number of events. The learned number of events may vary across engine cylinders, across engine operating conditions, and further may vary as a function of each cylinder's misfire propensity and severity over various engine operating conditions.

Abstract: Internal combustion engine camshaft phaser position detection with a single position sensor fixed in position relative to a rotatably driven member rotating in constant phase with the engine camshaft and a rotatably driving member rotating in constant phase with the engine crankshaft. Teeth or slots are provided on the driven and driving members and pass in proximity to the sensor for varying a sensor output signal which is processed to determine the relative time of passage of the driving and driven members to determine relative phase therebetween.
