Abstract: A disposable hand piece can be attached at the end of a laser beam delivery assembly. The hand piece can be longitudinally tapered and generally wedge-shaped in its width and slightly bent so as to form a tool which can be comfortable grasped by a Dentist for purposes of more accurately controlling the laser beam applied through the laser hand piece. The hand piece can include an internal means to supply fine mist of air and water for cooling of the treated area. The hand piece is constructed of inexpensive plastic materials and is designed to be disposable after a single use.

A third application at the computer creates and edits a keyboard function map for the user interface device. The computer sends the keyboard function map to the user interface device. The user interface device allows a user to edit images for the laser to print and control operation of the laser.

Abstract: A method for printing is described. The method includes providing a printing system for printing a code on a product moving in a direction. The code is constructed from a plurality of pixels in a first data set indicating the positions of the pixels and generates a corrected data set indicating the position that each pixel would occupy if each pixel was moved at the velocity of the product until the pixel was printed. The method also includes printing the code according to the corrected data set.

Abstract: A technique of applying a protective layer and an absorbing layer to a wrapping material for wrapping a product, such as a candy bar or potato chips. The protective layer prevents a laser marking tool from puncturing the film. The absorbing layer absorbs radiation from the laser marking tool to show a sequence of symbols and characters, such as a date, bar codes, an image or a logo. Another technique for marking codes on a thin film may include applying a thermal coating or ink on a thin film. A device with a ribbonless, non-contact thermal print head may apply heat to specific portions of the thermal coating to mark symbols and characters. The portions of the thermal coating exposed to heat will change color.
