  • Publication number: 20240136217
    Abstract: A manufacturing system includes a substrate disposed on a conveyer system. The conveyer system includes a pair of side supports. The substrate is moved on the conveyer system until the substrate is disposed over a bottom support block. The bottom support block is raised to physically contact the substrate. A transfer arm module is provided. The transfer arm module includes a flat bottom surface and an opening formed in the flat bottom surface. The transfer arm module is disposed with the flat bottom surface physically contacting the substrate opposite the bottom support block. A vacuum is enabled through the opening of the transfer arm module. The substrate is lifted off the bottom support block using the vacuum. The substrate is moved over a printing pallet using the transfer arm module. The vacuum is disabled when the substrate is in a positioning area of the printing pallet.

  • Patent number: 11945004
    Abstract: A semiconductor manufacturing equipment cleaning system has a multi-station cleaning and inspection system. Within semiconductor manufacturing equipment cleaning system, a tray cleaning station uses a first rotating brush passing over a first surface of a carrier and possibly semiconductor die, and a second rotating brush passing over a second surface of the carrier and semiconductor die opposite the first surface of the carrier and semiconductor die. Debris and contaminants dislodged from the first surface and second surface of the carrier by the first rotating brush and second rotating brush are removed under vacuum suction. A conveyor transports the carrier through the multi-station cleaning and inspection system. The first rotating brush and second rotating brush move in tandem across the first surface and second surface of the carrier. Air pressure is injected across the first rotating brush and second rotating brush to further remove debris and contaminants.

  • Publication number: 20240070183
    Abstract: A computer-implemented method according to one embodiment includes generating a first matrix based on words extracted from documents, and generating a second matrix based on deduplication chunks. The deduplication chunks include words of the documents. Word clustering is performed based on an analysis performed on the second matrix. Each cluster of the words represents a feature of at least one of the documents. The method further includes generating a third matrix based on the first matrix and the clusters, and performing text mining using the third matrix. A computer program product according to another embodiment includes a computer readable storage medium having program instructions embodied therewith. The program instructions are readable and/or executable by a computer to cause the computer to perform the foregoing method.

  • Patent number: 11821986
    Abstract: The present invention provides a target tracking method, system, device and storage medium, which includes: Determining a target area based on the current frame of a training sample, extracting and fusing histogram of oriented gradient (HOG), color naming (CN), and color space HSV features of the target area to obtain a target template; Determining a target function according to the target template and a spatial regularization weight factor; Introducing the Sherman-Morrison formula into the alternating direction method of multipliers (ADMM) to accelerate the solution of the target function and obtain the response value; Iterating the target tracking model when the response value meets the preset confidence threshold until training is completed to obtain a trained target tracking model, and tracking the target in the video to be observed by using the trained target tracking model.
