  • Patent number: 10940561
    Abstract: A removably attached coupling assembly can be used to be attached to a laser focus optic assembly of a liquid jet guided laser system. The coupling assembly can include a coupling body, a window assembly, and a nozzle assembly. The coupling assembly thus can allow the independent and separate servicing of the window and the nozzle. For example, to service the window, the coupling assembly can be first detached from the laser focus optic assembly, exposing the top portion of the coupling assembly. The window assembly then can be detached from the coupling assembly. The window can be removed from the window assembly for servicing, such as being repaired or replaced.

The adjustment data can be applied to the pixel values of the content to modify the content in order to enable a visualization of the content within an object. The image portion can be modified such that the object appears to “blend” with and appear within the object. Image transformation techniques can be used to project the modified content onto a representation of an object. Thereafter, a visualization or preview of the content within the representation of the object can be presented.

The material removal is done using laser beam pulses, which are directed through a deflection device onto points of incidence within a pulse area with a specified outside contour on the workpiece. Multiple machine axis drives position the workpiece and the deflection device relative to one another so that the pulse area is oriented essentially at right angles to the emission direction of the laser beam pulses and at right angles to the section of the tool surface that has already been produced and that borders the pulse area. While the material is being removed, the at least one machine axis drive moves the pulse area relative to the workpiece along a specified path of motion while maintaining the orientation.

  • Patent number: 10440779
    Abstract: A process for the production of laminar electric resistances having plan geometry according to a predetermined pattern. The laminar electric resistances are formed by a metallic foil, a rigid first template, a trace and at least one sheet of insulating material. The trace is shaped to substantially trace the plan geometry of the predetermined pattern forming a path. The first template includes a fixing means adapted to fix the metallic foil. The trace has a height from the base between 10 and 50 mm. The process includes the steps of: fixing the metallic foil onto the first template by means of fixing means; cutting, according to a predetermined pattern, the metallic foil with a laser to obtain a cut foil; adhering a first sheet of insulating material to a surface of the cut foil which is distal from the first template; and detaching the cut foil from the first template.

  • Patent number: 10425626
    Abstract: The laser projection display device (1) includes a laser beam source (5), a laser driver (4) driving the laser beam source, and an image processing unit (2) supplying a display image signal to the laser driver. The image processing unit applies a preliminary emission signal (53) to perform preliminary emission to an image signal (50) in a predetermined period (t0 to t1) immediately before a black pixel signal is switched to a signal except for the black pixel signal when the image signal has a black pixel duration. In particular, the preliminary emission process is performed when the laser beam source is operated in a dark image region while being reduced in maximum light intensity, and, as the preliminary emission signal, a signal (L0) corresponding to a light intensity which is 1/10 or less a maximum light intensity (La) in the dark image region.
