Abstract: A hitting apparatus is provided, including a supporting unit, at least a linking unit, and an attaching device. The apparatus includes foldable supporting legs, an adjustable supporting rod, an adjustable hanging arm, an adjustable extension arm, connection elements, attaching elements and attaching ball. The adjustable extension arm is flexible, which can be adjusted at any direction by hand, or foreign force. The connections between connection elements are detachable and releasable upon hit by bat or other subjects. The hanging arm is engaged to the top of supporting rod, and adjustable in length and angles and easy to be detached from the support rod to become a hand held hitting training apparatus. The attaching parts of hook/loop, magnets, adhesive or rubbers holding the ball with minimum detaching releasable force required, The present invention can enhance the focus of the batter on the ball and have a clear hit on the ball.

Abstract: The invention relates to graftable polymers comprising biologically active agents and the use of such polymers in the manufacture of shaped articles, such as implantable medical devices and catheters. The graftable polymers are covalently grafted to a surface via one or more grafting moieties incorporated into the pharmaceutically-active graftable polymer. The coated articles of the invention can further comprise tie-coats, and the ratio of polymer:tie coat can be used to adjust the rate of drug elution.

Abstract: A hitting apparatus is provided, including a supporting unit, at least a linking unit, and an attaching device. The apparatus includes foldable supporting legs, an adjustable supporting rod, an adjustable hanging arm, an adjustable extension arm, attaching rods or strings, and attaching ball hook/loop, magnets or adhesives. The hanging arm is engaged to the top of supporting rod, and adjustable in length and angles and easy to be detached from the support rod to become an individual hitting training apparatus. The attaching parts of hook/loop, magnets or adhesive hold the ball with attaching loop or metal tape or coating. With the holding of the ball by the hook/loop, magnet or adhesives, the present invention can be a tee free design to enhance the focus of the batter on the ball and have a clear hit on the ball. The present invention is easy to assemble, adjust, use, carry around and store.

Abstract: A printable, pressure-sensitive adhesive ("PSA") tape, particularly a self-wound tape, which comprises a polyester film substrate, a rubber base prime coat and an adhesive which can be fire-retardant. The PSA tape has high adhesive properties and a novel release mechanism which does not use any conventional release agents.
