An apparatus for attaching a gusset to a panel includes a gusset folder that receives and folds a gusset material to form the gusset. The golf ball has an innersphere with a plurality of lattice members. The RF absorbing material may comprise a layer of such material upon a surface of a ground plane within a housing of the transmitter, andor on an interior surface of the housing, andor on an exterior surface of the housing. When a leash is attached to the leash connector, a directional pull on the leash causes the leash connector to slide in the direction of the pull, pulling the limited slip loop to the side and moving the pull off the center of the dog’s chest, thus decreasing the opposition reflex. The arms include leaf-spring contacts which resiliently and non-fixedly engage the secondary circuit board which is connected to control buttons on the steering wheel. In some embodiments, a medical device includes a member having a first portion with a first wall thickness, and a second portion with a second wall thickness, wherein the first portion is circumferentially rotated.
