Abstract: A unique method of simultaneously marking both packaging and prepackaged articles such as tablets, pills, medical devices, and the like on the fly, without the deposition of ink or other marking materials on their surfaces, and without degrading the prepackaged articles or breaching the packaging. The markings can serve as unique identifiers for each individual marked article (serial numbers), as product identifiers (bar codes), or as tamper protection (positioning symbols), or the like. One product can be provided with all three types of marking, if desired. A radiation sensitive marking material such as titanium dioxide, for example, can be provided in both the article and a markingly associated window of packaging material. The article and the window together provide a marked pair.

Abstract: A unique method of marking individual consumable articles such as tablets, pills, and the like on the fly, without the deposition of ink or other marking materials on their surfaces, without degrading the articles, and without precise positioning and holding of the articles. Titanium dioxide is provided in a visible layer of the consumable articles in an amount that is effective to provide a mark when exposed to an effective amount of ultraviolet laser energy. The energy is emitted in a predefined pattern on the surface of the articles so as to define the desired marking pattern. Marking is effectively instantaneous, thereby permitting the target articles to be marked while in motion to efficiently and inexpensively provide marking rates that are as much as twenty times more than those provided by prior art ink deposition systems. Marking can be accomplished even when the articles are encapsulated in ultraviolet transparent packaging.

Abstract: Method of improving wetting and adhesive properties of dielectric materials by injecting electrical charges into the substrate under conditions such that the primary effect on the surface is that of charging so that improved wettability of the surface will be achieved. Flowable materials are then applied to the surface and cured in situ to permanently adhere the flowable materials to the surface.
