The present invention relates to a method of high-speed recording and reading data on or in a layer (10) of a first material and to a device for high-speed recording and reading data on or in a layer (10) of a first material using a laser source (19, a galvanometer (4) and a digital micromirror (5) adapted to emit multiple laser beams.

A pattern forming apparatus for forming a pattern by emitting a scanning light onto a plurality of base materials conveyed in a predetermined conveying direction, includes a plurality of emitting units including a first emitting unit and a second emitting unit. The first emitting unit includes a first light source unit to emit a first laser light; a first conveying direction light scanning unit to scan the first laser light in the predetermined conveying direction; a first intersecting direction light scanning unit to scan a scanning light, scanned by the first conveying direction light scanning unit, in an intersecting direction that intersects the predetermined conveying direction. Further, there is a first light emitting unit to emit a first scanning light, scanned by the first intersecting direction light scanning unit, onto a base material among the plurality of base materials.

There is described a metal workpiece generally having a surface and an identifier marked on said surface. The identifier has cells each having a corresponding cell size, including bright cells corresponding to a first binary value and dark cells corresponding to a second binary value different from the first binary value. The dark cells include a center portion being recessed relative to the surface thereby leaving a recess bounded by a peripheral wall in the corresponding dark cell, the recess having a depth of at least 100 microns and having an opening with a width ranging between 400 microns and 1750 microns and representing between 30 percent and 99 percent of the corresponding cell size such that the corresponding dark cell appears dark to an optical reader. The depth, the width and the cell size of the dark cells provide a shot blast resistance to the laser-marked identifier.

A device for recording information in a data carrier, comprising a data carrier receptacle for partially receiving the data carrier in a planar manner; a data carrier cover arranged relative to the data carrier receptacle, which is designed for holding the data carrier between the data carrier receptacle and the data carrier cover; a laser source for the controlled emission of a laser beam designed to effect irreversible changes of the data carrier with the laser beam; and a mount that receives the data carrier receptacle to be pivotable about a pivot axis. The data carrier receptacle has two or more positions, that allow the data carrier receptacle to be received in the mount in such a way that the data carrier receptacle can be repositioned about the pivot axis in a pivotable manner.

Provided is a laminated body in which a print layer is provided downstream of a laser color development layer without lowering quality. A card is provided with an offset print layer laminated on a base material, a buffer layer laminated on the offset print layer and having translucency, and a laser color development layer laminated on the buffer layer. The buffer layer minimizes scratches on the offset print layer that occur with the heat generation of the laser color development layer.

This disclosure is related to arranging micro devices in the donor substrate by either patterning or population so that there is no interfering with non-receiving pads and the non-interfering area in the donor substrate is maximized. This enables the transfer of micro devices to a receiver substrate with fewer steps.

Software and lasers are used in finishing apparel to produce a desired wear pattern or other design. A technique includes determining a fabric's response to a laser, capturing an initial image of a wear pattern on a garment, and processing the initial image to obtain a working image in grayscale. The working image is further processed to obtain a difference image by comparing each pixel relative to a dark reference. The difference image is converted to a laser values image by using the previously determined fabric response to the laser.
