Abstract: A method and system for testing and improving a user's visual tracking skills and reaction time to a moving object includes simulating motion of an object by individually illuminating LEDs in longitudinal sequence along individually selectable paths having different positional approaches toward a target. A user activates a switch or interrupts a beam with the intent of terminating the sequence in time coincidence with illumination of a designated LED proximate the target. A microprocessor detects the time difference between illumination of the designated LED and termination of the sequence by the user as measure of the user's visual tracking and reaction time. In one embodiment the user is a baseball batter, the target is a home plate and the selectable paths are simulations of straight and breaking pitches.

Abstract: The present invention provides filled aqueous caulk and sealant compositions made from high solids aqueous binders chosen from copolymers having a mixture of backbone acid and hydroxyl groups that are copolymerized from 0.5 to 7.5 wt. %, based on total monomer weight, of an hydroxyl group containing monomer, and mixed backbone acid copolymers that are copolymerized from methacrylic acid (MAA) with a second acid monomer having a lower pKa than the pKa of MAA. Preferred, compositions comprise one or more organosilane exhibit the adhesion and joint movement capability required by ASTM C-920-08, as well as good weatherability and aged wet adhesion to glass, even at a filler to binder ratio of 0.2:1 to 4:1.
