The invention relates to a plasma source with an oscillator having an active element and a resonator connected to the active element. The tire has arranged in a tread two circumferential fine grooves disposed on opposite sides of the equatorial surface of the tire and extending in the circumferential direction of the tire, and the circumferential fine grooves define a center land section. The composition has a property of gelling instantaneously in the presence of an aqueous phase. Each metal extrusion has a locking hole and a bonding surface, which is higher than the die pad. A motion transfer linkage is provided to force simultaneous pivotal movement of both sub-frames when either is moved, so as to involve compound muscle groups in an exercise movement. The printed capacitive sensors on film are fastened with a silk-screen applied liquid water-based adhesive and face the graphics printed side of the first plastic film.
