Abstract: Motion of an image of a scene being captured by a digital image acquisition device is detected and used to control parameters of illumination of the scene by a flash lamp that is typically built into the device. Parameters that may be controlled include the intensity, duration and timing of light emitted by the flash lamp. Such control of the flash illumination is preferably performed in conjunction with adjusting one or more exposure parameters used to capture an image. Such exposure parameters include duration, aperture and sensor gain. Motion blur caused by movement of the camera or by movement of an object within the scene being photographed is reduced by selecting appropriate exposure parameters and flash light characteristics.

Abstract: An approach is presented for designing a polymeric layer for nanometer scale thermo-mechanical storage devices. Cross-linked polyaryletherketone polymers are used as the recording layers in atomic force data storage devices, giving significantly improved performance when compared to previously reported cross-linked and linear polymers. The cross-linking of the polyaryletherketone polymers may be tuned to match thermal and force parameters required in read-write-erase cycles.

Abstract: A method for photothermal information recording, reading and erasing consists in that the surface of a recording medium (1) is charged prior to the photothermal recording process and then exposed, during photothermal information recording and erasing, to a modulated electromagnetic beam (8) localized to a spot size of the order of one information unit with the energy exceeding the energy required for softening the material of the recording medium (1), and, during information readout, with the energy less than that for softening the material of the recording medium (1), the surface of the recording medium (1) being discharged before erasing information.

Abstract: Process for manufacturing a record carrier having a cuttable copper layer, wherein a copper layer is precipitated onto a substrate in an electrochemical bath and a desired Vickers hardness in the precipitated copper layer is obtained by controlling the concentration of brightener additives. The copper layer is precipitated in a recrystallizable phase, and the recording is cut while the copper layer is in its recrystallizable phase.

Abstract: Apparatus for recording an information signal on a metallic record carrier. The information is impressed on the carrier by cutting a groove therein by means of a stylus, the groove being characterized at each point by a slope or modulation pitch angle. The stylus has a longitudinal axis, a leading edge substantially parallel to this axis and a trailing edge. The angle between the longitudinal axis of the stylus and a normal to the surface of the record carrier is greater than 10.degree. and not more than a value which would make the angle between the trailing edge of the stylus and the surface of the record carrier less than the maximum modulation pitch angle. The stylus is movably attached to a fixed structure by a mounting member and is electromagnetically excited by a driving member to shape the grooves in the record carrier in accordance with the information signal.

Abstract: A laser engraving machine for engraving cylindrical intaglio printing members is arranged to turn the surface of a printing member and engrave it simultaneously. This is not only more efficient but ensures that an accurate relationship is maintained between the engraving head and the turned outer surface of the printing member 3. The engraving machine includes a slide-way 2 extending parallel to the axis of rotation of the printing member 3, a traversing carriage 1 mounted for movement along the slide-way 2 and having a primary sliding carriage 4 mounted on it, and the primary sliding carriage has a secondary sliding carriage 5 mounted on it. The primary and secondary sliding carriages carry a turning tool holder 8 and a laser engraving head 10.

Abstract: A method of replicating data from a master transmissive optical data storage medium whereby the resulting product displays areas of low reflectivity and high reflectivity. Actinic radiation is shone through transmissive areas onto a silver-halide emulsion photosensitive medium. The photosensitive medium is then chemically developed black. Next, the developed medium is fogged to create a latent image layer of silver precipitating nuclei. Finally, the fogged medium is placed in a monobath comprising a weak silver-halide reducing agent and a rapid-acting silver-halide solvent for partial chemical development and substantial physical development. The resulting product displays areas of low reflectivity, which correspond to the transmissive areas of the master, in a reflective field.
