Abstract: A laser scanning system with sufficient power to drill very small holes or marks in materials. The holes or marks are so small that they cannot be seen with the human eye. These holes and marks can be arranged in an ID matrix barcode or other barcode that can be detected with a specially designed barcode reader.

Abstract: A ladder leveling apparatus is provided which is designed for easy installation onto and removal from a ladder, which may be installed to only one leg of a ladder rather than two legs, which is light in weight, which is easily adjustable by the end user, an apparatus which does not require the ladder to be adapted to the leveling apparatus through the use of holes and bolts, a ladder leveling device that adapts to a wide variety of ladders having a variety of leg sizes, a ladder leveling device that is applicable even for use for leveling with a step ladder.

Abstract: The invention relates to a web material comprising a carrier sheet, a continuous pragmatic sheet and an adhesive layer wherein said adhesive layer is between said carrier sheet and said pragmatic sheet, said adhesive layer more strongly adheres to said pragmatic sheet and said pragmatic sheet is narrower than said carrier sheet wherein the side of said carrier sheet in contact with said adhesive is reflective.

Abstract: A marking apparatus for printing and laser treating a workpiece in a single registration with a pallet. Printing heads and pallets are moveable relative to each other to apply an ink to the workpiece, such that, upon locating the printing head in relocated position, a laser beam can controllably intersect the workpiece.

Abstract: A region of a pile fabric is impacted with a laser at spaced illuminated areas in a dithered image, wherein the laser energy and duration of impact in the illuminated areas are selected to shorten the fibers within the illuminated area. The spacing of the illuminated areas within the region and the amount of shortening within the illuminated areas are selected to essentially maintain a hand or feel of the pile fabric. Fleece and corduroy can be sculpted to provide a three-dimensional image, while maintaining the hand of the fleece. In dyed pile fabrics, the illuminated areas can be selected to change the dye distribution within the pile material to provide an altered coloration.
