Abstract: A treadmill includes a frame, a deck assembly, at least one deck deflection sensor, and a control system. The deck assembly is supported by the frame. The deck assembly includes a longitudinally extending deck, at least first and second rollers, and a belt positioned about the deck and the first and second rollers. The deck deflection sensor is coupled to the deck. The deck deflection sensor is a contactless displacement sensor including an electrical intermediate device and an aerial. The control system is operably coupled to the at least one deck deflection sensor.

Abstract: A golf ball (20) in accordance with the principles of the present invention has a core (22) with a low compression, but has at least two additional layers (24, 26) that provide for increased durability and control. The core (22) is formed of a polybutadiene compound that produces a zero (or less) compression. The mantle (24) is molded around the core (22) using terpolymers, which are comprised of ethylene, acrylic acid and n-butyl acrylate, with 100% of the acrylic acid groups neutralized with metal ions. The mantle (24), when molded, yields a deflection of greater than 0.170 inches under an applied static load of 200 lb. This correlates to a PGA compression of between about ?20 and 15. The cover (26) is molded using conventional ionomers and “very low modulus” ionomers (V.L.M.I.), and has a hardness of between about 50 and 75 on a Shore D scale.

Abstract: A bat has an elongate tubular striking member of a first material, and an elongate handle member of a second material. The handle may be of composite material laid up in selected layers and orientation to produce selected weight distribution, strength, and stiffness and improved batting capabilities. The striking member and handle member may have juncture sections which are substantially rigidly interconnected through mating configurations.
