  • Patent number: 6986926
    Abstract: The invention relates to a method for the recording of data, in particular, personal data on and/or in a data support, by means of electromagnetic radiation. A corresponding data support is made ready, on and/or in which a dye is at least locally provided and said dye is irradiated by means of said electromagnetic radiation of at least one wavelength range, such that a change in the color of the dye by bleaching occurs in the region of the irradiation. Said color change may be determined by machine and/or by the human eye. An improved counterfeiting and manipulation security for the data support is thus achieved.

  • Publication number: 20050224051
    Abstract: A method for operating a fuel metering system of a motor vehicle is provided, in which fuel is delivered by at least one supply pump to at least one high pressure area, the fuel being injected by at least one fuel injector from the high pressure area directly into at least one combustion chamber, at least one sensor detecting the pressure in the high pressure area, and at least one pressure regulating element being provided for adjusting the pressure in the high pressure area.

  • Publication number: 20050181498
    Abstract: The present invention relates to a multi-layer body which is a paper document with a hot stamping film embossed thereon. The hot stamping film has a laser-sensitive layer in which a laser-induced color image is produced by laser treatment. Arranged on the document are further security identifications such as a security print, which is in the form of guilloche patterns, fluorescent threads, and a security strip. Water marks are also provided in the paper document.

  • Publication number: 20050142342
    Abstract: The present invention relates to a process for increasing the level of safeguard in respect of forgery of paper documents. For that purpose, applied to the paper document is a transfer film or laminating film having a laser-sensitive layer. This multi-layer body is then treated with laser radiation. In that case, a laser-induced marking is produced in the laser-sensitive layer, for example, by laser-induced bleaching, laser-induced color change or laser-induced blackening. Respective individualization of the document can be effected by way of that laser-induced marking.

  • Publication number: 20050118537
    Abstract: The invention relates to a process for the production of a multi-layer image, preferably a multi-color image. A transfer film which is applied to a paper substrate and which is treated with laser irradiation is used. The transfer film has a laser-sensitive layer and a background layer arranged therebeneath. The laser-sensitive layer comprises laser-sensitive material, for example laser-sensitive pigments or other laser-sensitive coloring agents. The laser-sensitive material in the layer is region-wise bleached by laser irradiation. That results in a so-called laser-induced image component. As it is transparent or partly transparent, the background layer which is arranged therebeneath and which can have a printed image then becomes visible from above in that region. That therefore gives a multi-layer image which is formed by the laser-induced image component and by the background layer jointly.

  • Publication number: 20040265552
    Abstract: Described is a multi-layer body having two laser-sensitive layers 4, 32. The multi-layer body is a body laminated from the overlay films 30, 32, the inlets 90, 90 and the further overlay films 30, 30. At its underside the upper overlay film 30 has a layer structure applied there, by the application of a hot stamping film. The layer structure comprises a lacquer layer 50, a reflection layer 5r, a laser-sensitive layer 4, a background layer 5 and an adhesive layer 6. A diffraction and/or hologram structure 5b is provided in the lacquer layer 5c, the reflection layer 5r and the laser-sensitive layer 4. The second laser-sensitive layer is formed by the carbon-doped overlay film 32.

  • Publication number: 20040007324
    Abstract: The invention relates to a method for producing a multi-layer document card, especially an identity card made of plastic, comprising several layers. Said card comprises a card core with at least one card core layer, a protective layer on at least one side of said card core, and adhesive layers between the individual card layers. The card core is printed on either on one or two sides.

  • Patent number: 6223714
    Abstract: Switching off a fuel pump of a fuel supply system for the internal combustion engine with the aid of a signal from a retardation sensor of the airbag in the event of a crash in which the motor vehicle is involved is known. To further enhance the safety of motor-vehicle occupants, a method is proposed for an internal combustion engine which has at least one fuel injection valve, a fuel supply system for the at least one fuel injection valve, and a sensor for detecting a crash. After the crash has been detected by means of the sensor, the fuel injection valve is brought into an open position, with the result that fuel is discharged from the fuel supply system of the fuel injection valve into a combustion chamber of the internal combustion engine. The method according to the invention is provided for internal combustion engines with at least one fuel injection valve.
