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.

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

Abstract: A method of measuring an absorbed dose of ionizing radiation using a measuring device that bears an integral identification mark, comprising the steps of: providing a support; disposing on the support a first region capable of measuring an absorbed dose of ionizing radiation; disposing on the support a second region that bears integral identification mark; exposing at least the first region to a dose of ionizing radiation; and reading the signal from the first region.

Abstract: An apparatus for forming transitioned edges in patterns formed by a scanning laser in a dyed textile material is disclosed. The transition rate between the untreated material and the treated material is controlled by passing a scanning laser beam through a mask prior to the laser beam reaching a focal point. An apertured mask can be employed to control the transition rate, wherein the location of the aperture relative to the focal point of the laser beam and configuration of the aperture periphery are manipulated to effect the transition rate.

Abstract: A dosimeter comprising: a support; at least one first region disposed on said support, the region containing amino acid and a binder; and at least one second region disposed on said support; wherein the first region is capable of measuring an absorbed dose of ionizing radiation and the second region bears an identification mark.

Abstract: A system for providing motion picture photographic film with encoded information, such as unique film footage and frame identification, which can be machine read prior to film processing. This system provides machine readable encoded information markings on the raw stock film which may be read in a camera or other photoprocessing device with a reader prior to or concurrent with the film image capture process. The machine readable encoded information markings may be easily converted into a “video image” for display in a real time video from a CCD imager in the film camera or other device. Furthermore this pre-processing machine readable encoded information may be used in conjunction with optical latent image recorded information which becomes machine or human readable after processing as presently provided by film manufacturer's according to industry standards.

Abstract: An apparatus for laser marking indicia on a moving photosensitive web by impinging laser energy upon the moving web with a laser printer device. The laser printer device is provided with a nozzle element that concentrates beams of radiation onto the web with substantially reduced incidences of fog spots on the web. The nozzle element extends circumferentially, substantially around a laser beam tube and the predetermined optical path defined by laser beams emanating from the laser beam tube.

Abstract: An apparatus for laser marking indicia on a moving photosensitive web substantially reduces fog spots on the web caused by impinging laser energy. A nozzle element configured to conform to the outlet end of the laser beam tube enables reduction of fog spots on photosensitive web.

Abstract: A nozzle element for laser marking indicia on a moving photosensitive web substantially reduces fog spots on the web caused by impinging laser energy. The nozzle element is configured to conform to the outlet end of the laser beam tube to eject particulates through vacuum outlet port.

Abstract: A method of controlling peak power of a radiant energy emitting system, such as lasers adapted for use in laser edge marking apparatus, reduces fog spots on the web caused by impinging laser energy. A laser printer has an attenuating member provided in the optical path of a laser beam tube for controlling peak power to each one of the plurality of lasers.

Abstract: An apparatus for laser marking indicia on a moving photosensitive web substantially reduces fog spots on the web caused by impinging laser energy. A laser beam attenuating member arranged in the laser beam tube enables control of peak laser beam power thereby significantly reducing the incident of fog spots on the film surface.

Abstract: A method for creating a decorative contrast design on motorcycle and automobile parts by acquiring a decorative design into a computer connected to a laser and X-Y positioning galvanometers and controlling the laser pulse rate and fluence as the beam is scanned across the part according to a program to effect the acquired decorative contrast design on the part surface.

Abstract: The present invention relates to writing and marking images on ceramic surfaces in a reversible fashion. The images are marked using a laser. The images are erased by heating the ceramic surfaces to a temperature of approximately 200.degree. C. or using a CO.sub.2 laser.

Abstract: The invention relates to a system that uses human readable microfilm to store information and retrieve that information for later use in a computer. The microfilm is put into a Computer Input Microfilm (CIM) Reader that scans the film and converts the characters or text in the image into computer codes. An Optical Character Recognition algorithm is used to identify the text character and the CIM Reader converts that character into a computer code.
