  • Patent number: 11951638
    Abstract: A method for determining a standard depth value of a marker includes obtaining a maximum depth value of the marker. A reference depth value of the marker is obtained based on a depth image of the marker, and a Z-axis coordinate value of the marker is obtained based on a color image of the marker. When the reference depth value and the Z-axis coordinate value are both less than the maximum depth value, and a difference between the reference depth value and the Z-axis coordinate value is not greater than 0, the depth reference value is set as the standard depth value of the marker; and when the difference is greater than 0, the Z-axis coordinate value is set as the standard depth value of the marker.

  • Publication number: 20240084455
    Abstract: Some implementations described herein include systems and techniques for fabricating a wafer-on-wafer product using a filled lateral gap between beveled regions of wafers included in a stacked-wafer assembly and along a perimeter region of the stacked-wafer assembly. The systems and techniques include a deposition tool having an electrode with a protrusion that enhances an electromagnetic field along the perimeter region of the stacked-wafer assembly during a deposition operation performed by the deposition tool. Relative to an electromagnetic field generated by a deposition tool not including the electrode with the protrusion, the enhanced electromagnetic field improves the deposition operation so that a supporting fill material may be sufficiently deposited.

  • Publication number: 20230407554
    Abstract: The present invention discloses a mesh laundry bag, which comprises a mesh container and an elastic closure unit. The mesh container comprises an opening. The elastic closure unit is disposed on the opening to maintain its closed state. By replacing the traditional closure units like zippers with the elastic closure unit, the mesh laundry bag enables one-handed operation for opening and closing, allowing users to use their other hand to place laundry inside the bag. Moreover, the absence of closure units such as zippers significantly reduces the risk of clothing damage.
