Abstract: A handheld device (100), a graphical handwriting user interface (“HUI”), a method of interfacing handwritten text and a program product therefor. A lower portion of a touch-enabled display is designated as a handwriting input area (104). Recognized text is displayed at the top of the screen. As each handwritten word is entered (142) into the designated screen input area, a check is made (144) to determine when the handwritten entry is complete by pressing a space key or by a special pen gesture. When the handwritten entry is complete, the handwriting recognition engine matches (146) the handwritten input against words in the system dictionary as supplemented by the user dictionary and a confidence score is attached (148) to the top scoring word.

Abstract: A method of radiation induced dry etching of a metallized (e.g. copper) substrate is disclosed wherein the substrate is pattern-wise exposed to a beam of laser radiation in a halogen gas atmosphere which is reactive with the substrate to form a metal halide salt reaction product to accelerate the formation of the metal halide salt without its substantial removal from the substrate. The metal halide salt is removed from the substrate by contact of the substrate with a solvent for the metal halide salt.
