Abstract:
1. A method for processing an object having opposing major surfaces including first and second surfaces, said method comprising: applying heat in a controllable way to the object during a background heating mode using a heating arrangement thereby selectively heating the object to at least generally produce a temperature rise throughout the object; heating the first surface of the object using the heating arrangement in a pulsed heating mode, cooperating with said background heating mode, by subjecting the first surface to at least a first pulse of energy having a pulse duration; and controlling said background heating mode in timed relation to said first pulse such that the first pulse is applied at a point in time during the background heating mode and controlling the background heating mode includes reducing heat applied by the background heating mode within a particular interval in relation to initiating said first pulse.
