We combine superplastic forming with adhesive bonding to produce quality multisheet sandwich panel structures, especially those using a superplastic aluminum alloy, such as Al 2004, Al 8090, or Al 1570. The microphones and circuitry associated with the volume control apparatus are located in an autonomous, preferably portable, remote control unit that will work with any existing audiovideo device that is configured to respond to a remote control input. At least one optical transmission circuit is used to form at one stationary laser beam from the primary laser beam and direct the stationary laser beam towards at least one laser shock peening target area. The actuator may include an inner housing having an outwardly extending flange, and an outer housing disposed about the flange of the inner housing.
