A polylactic acid-based decorative body including a polylactic acid resin-containing substrate, a polylactic acid resin-containing adhesion layer provided on the substrate, and at least one functional layer that is formed on the adhesion layer by applying an acrylic urethane coating composition, wherein in the acrylic urethane coating composition, the molar ratio of OH groups in an acrylic resin to NCO groups in a polyfunctional isocyanate is 1:4 to 1:6.

A composite masking system and method for improving the invisibility of high-definition video watermarking. The composite masking system includes a watermark generation module, a mask generation module, and watermark embedment means. The watermark generation module generates a basic watermark pattern using a private key, and generate a watermark pattern by repeatedly extending the basic watermark pattern. The mask generation module generates a Noise Visibility Function (NVF) mask using NVF masking means, an adaptive dithering mask using adaptive dithering masking means, and a contour mask using contour masking means. The watermark embedment means generates a composite mask by multiplying the NVF mask, the adaptive dithering mask and the contour mask together, multiplying the composite mask and the extended watermark pattern together, and embedding the result of the second multiplication in the luminance channel of an original image.

A method and system for compensating for a time discrepancy. A first and a second vehicle-to-X communication system resort to an external time base. The first vehicle-to-X communication system determines a first internal time base from the external time base and the second vehicle-to-X communication system determines a second internal time base from the external time base. The first vehicle-to-X communication system sends vehicle-to-X data and the second vehicle-to-X communication system receives vehicle-to-X data. The vehicle-to-X data to be sent include a time stamp generated from the first internal time base and captured ambient sensor data include a first time stamp generated from the second internal time base. Alignment of the captured ambient sensor data with the received vehicle-to-X data is used to determine the time discrepancy between the first internal time base and the second internal time base and to compensate for it using a correction value.

The invention relates to devices and methods in mass spectrometers for the generation of ions of heavy molecules, especially biomolecules, by bombarding them with uncharged clusters of molecules. The analyte ions which are generated or released by cluster bombardment of analyte substances on the surface of sample support plates show a broad distribution of their kinetic energies, which prevents good ion-optical focusing. In the invention, the kinetic energies are homogenized in a higher-density collision gas. The collision gas is preferably located in an RF ion guide, more preferably an RF ion funnel, which can transfer the ions to the mass analyzer. The collision gas may be introduced with temporal pulsing, coordinated or synchronized with the pulsed supersonic gas jet. The collision gas may be pumped off again before the next supersonic gas pulse. In an advantageous embodiment, the collision gas can originate from the supersonic gas jet itself.
