  • Patent number: 10536684
    Abstract: A camera based depth mapping system. Depth information is coded with colors to make a laser-generated 3D depth map easier to interpret. In the event that the laser illumination is not sufficient, the depth information can have a low signal to noise ratio, i.e., the depth map can be noisy. Color noise reduction techniques are used to alleviate this problem.

  • Patent number: 10434599
    Abstract: The present invention provides an optical mask plate and a laser lift-off device. The optical mask plate comprises at least one totally-transmissive region and a blocking region surrounding the totally-transmissive region. The totally-transmissive region allows lasers having a predetermined wavelength to completely pass therethrough, while the blocking region does not allow the lasers having the predetermined wavelength to pass therethrough. The laser lift-off device comprises the optical mask plate. During the whole process of scanning a rigid substrate with the laser beam, as a laser emitter for emitting the laser beam can be in an on state all the time, the energy of the laser beam is nearly uniform in the process of scanning the rigid substrate with the laser beam, and in this way, edge portions of a flexible device can be prevented from being burned by the laser beam.

  • Patent number: 10427417
    Abstract: Systems and methods for generating machine-readable symbols on surfaces of objects using laser marking systems and processes. A specialized contour fill pattern for a laser beam path may be used that combines modules of a machine-readable symbol into bounded blocks or islands according to adjacencies and/or according to role (e.g., finder pattern, timing pattern, encoded payload data). In some implementations, the islands of modules may be filled using a laser beam path that traverses contour path lines from inner path lines to outer path lines. Once the islands have been generated during pre-processing, they are sorted to reduce the required time for the laser to “jump” (i.e., move with the laser turned off) from one island to a subsequent island to be filled. A filling pattern for bounded areas with sharp corners (e.g., squares, rectangles) may be simplified by rounding corners to optimize speed while maintaining suitable marking quality.

  • Patent number: 10399184
    Abstract: A method is provided for the internal processing of a transparent substrate in preparation for a cleaving step. The substrate is irradiated with a focused laser beam that is comprised of pulses having an energy and pulse duration selected to produce a filament within the substrate. The substrate is translated relative to the laser beam to irradiate the substrate and produce an additional filament at one or more additional locations. The resulting filaments form an array defining an internally scribed path for cleaving said substrate. Laser beam parameters may be varied to adjust the filament length and position, and to optionally introduce V-channels or grooves, rendering bevels to the laser-cleaved edges. Preferably, the laser pulses are delivered in a burst train for lowering the energy threshold for filament formation and increasing the filament length.

  • Patent number: 10066927
    Abstract: Inspection of microelectronic devices is described using near infrared light. In one example, a dielectric material layer on a substrate is illuminated with a near infrared light beam. The substrate has at least one contact land, the dielectric material layer overlies at least a portion of the contact land, and the substrate has at least one via defined in the dielectric material layer, the via exposing at least a portion of the contact land. Reflected near infrared light is reflected from the substrate at a camera. The position of the via is determined relative to the contact land from the reflected light beam using an image processing device.

  • Patent number: 10040271
    Abstract: A conductive grid formation system, apparatus, and related methods may include a drum having a conductive surface, an insulation layer coating said surface, and a grid pattern formed in the insulation layer to expose portions of the conductive surface. The drum surface may be rotated into and out of a chemical bath, such that a metallic grid is electrodeposited in the exposed portions of the conductive surface. A polymer sheet may be laminated to the surface of the drum and then removed, such that the metallic grid attaches to the polymer sheet and is removed with the polymer sheet. Heat, pressure, and/or adhesive may be utilized in various steps of the process, to facilitate preferential adhesion of the metallic grid to the polymer sheet.

  • Patent number: 10026192
    Abstract: A system for non-contact color harmony analysis is provided. The system may include an image acquisition system and an image analysis system. One or more cameras may take images of two regions of an object (e.g., a vehicle). The images may be transferred to the image analysis system, which may compare color values from each region and determine a color value difference. The color value difference may be compared to a predetermined threshold value to identify a possible color mismatch. The system may be used to analyze color harmony of adjacent vehicle components, for example, a front fascia and a fender or a rear fascia and a quarter panel.

  • Patent number: 9981339
    Abstract: A wafer having an off angle ? is produced from a hexagonal single crystal ingot having an upper surface, a c-plane exposed to the upper surface, and a c-axis perpendicular to the c-plane. The ingot is supported by a wedge member having a wedge angle ? equal to the off angle ?, thereby inclining the upper surface of the ingot by the off angle ? with respect to a horizontal plane. A modified layer is formed by setting the focal point of a laser beam inside the ingot and next applying it to the upper surface, thereby linearly forming a modified layer inside the ingot and cracks extending from the modified layer along the c-plane. The focal point is moved in the second direction to index the focal point by a predetermined amount.

  • Patent number: 9950389
    Abstract: An improved technique for calibrating the location of an individualized marking includes marking both a grid and an image on a calibration object. The technique uses the marked grid to measure the distance in two orthogonal directions from the current image location to the desired image location by counting the number of grids between the current image location to the desired image location.
