Abstract: The technology provides a method of reducing injury to a hamate bone for the lower hand while swinging a bat. The method includes determining a relief location for a knob of a wood baseball bat gripped with two hands, one above the other, with a lower hand being proximate to or contacting the knob. The process includes determining a location of a hamate hook on the lower hand, based on an intersection of a Kaplan's cardinal line and an ulnar border of ring line and placing a transferable substance over the hamate hook of the lower hand. A wooden baseball bat is selected and gripped with the grain positioned for a baseball to contact a hard side of a barrel during a swing. A location is identified to create a relief in the knob based on a transfer of the substance corresponding to a location of the hamate hook.

Abstract: A surface having a controllable contour. A plurality of closely-spaced panels form the surface. A post actuator is disposed beneath each panel vertex such that application of a force to a post actuator causes the post actuator to vertically extend and thereby a region of a panel above the post actuator to move upwardly. Release of a force on a post actuator causes the post actuator to contract vertically and permit a region of the panel above the post actuator to move downwardly. Each post actuator is independently controllable to extend and contract. A control system supplies water to each post actuator to vertically extend the post actuator and releases water from each post actuator to cause the post actuators to contract vertically. By controlling the supply and release of water to and from each post actuator a desired contour for the panels can be achieved.

Abstract: The placement determination control part 103 determines whether a ball was placed in a left trigger zone within the left detecting zone of the left capturing zone or a right trigger zone within the right detecting zone of the right capturing zone, using left and right cameras. The appearance determination control part 104 determines if an object appeared in a placement detecting zone, including a placement trigger zone, using the infrared sensor corresponding to the camera of that zone. The disappearance determination control part 105 determines if the ball disappeared from the placement detecting zone where the object appeared, using the corresponding infrared sensor. The next appearance determination control part 105 checks whether the ball appeared in a launch detecting zone, using the infrared sensor corresponding to the launch detecting zone adjacent to the placement detecting zone. The signal transmission control part 106 transmits a trigger signal accordingly.
