Methods Patents (Class 219/121.69)
  • Patent number: 10968562
    Abstract: Disclosed are methods and apparatus for cleaning a substrate, such as a fabric material, involving the application of optical energy to the substrate, typically in the form of a beam of light, where the energy of the beam causes removal of the contaminant from substrate, such as from the fibres of a fabric material. The cleaning may occur via any mechanism, including one or more of, alone or in any combination, ablation, melting, heating or reaction with the substrate or contaminant or agent introduced to aid in the cleaning. The optical energy is typically applied to a selected area of the substrate (e.g., as a beam), and the substrate and beam or optical energy source moved relative to one another so as to clean a larger area of the substrate, either by moving the substrate or the beam, or both. Movement of the beam with respect to the substrate can be attained through a beam scanning mechanism or through movement of the optical source itself.

  • Patent number: 10522737
    Abstract: A diaphragm for a piezoelectric micromachined ultrasonic transducer (PMUT) is presented having resonance frequency and bandwidth characteristics which are decoupled from one another into independent variables. Portions of at least the piezoelectric material layer and backside electrode layer are removed in a selected pattern to form structures, such as ribs, in the diaphragm which retains stiffness while reducing overall mass. The patterned structure can be formed by additive, or subtractive, fabrication processes.

    Abstract: An image information recognition processing method, device and a computer storage medium are provided. A first reference image and an image to be detected are acquired. Nth interception or cutting processing on the image to be detected is performed in a specified direction to obtain an Nth sub-image according to a first preset rule. First attribute values and/or second attribute values of the first reference image and the Nth sub-image are acquired respectively, the first attribute values being configured to represent color distribution information of the images and the second attribute values being configured to represent fingerprint information of the images. When the first attribute value and/or second attribute value of the Nth sub-image and the corresponding attribute value(s) of the first reference image meet a predetermined condition, it is recognized that the image to be detected to which the Nth sub-image belongs is matched with the first reference image.

  • 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: 10399227
    Abstract: A robot control system and a method for camera calibration verification is presented. The robot control system is configured to perform a first camera calibration, and to control a robot arm to move a verification symbol to a reference location. The robot control system further receives, from a camera, a reference image of the verification symbol, and determines a reference image coordinate for the verification symbol. The robot control system further controls the robot arm to move the verification symbol to the reference location again during an idle period, receives an additional image of the verification symbol, and determines a verification image coordinate. The robot control system determines a deviation parameter value based the reference image coordinate and the verification image coordinate, and whether the deviation parameter value exceeds a defined threshold, and performs a second camera calibration if the threshold is exceeded.
