  • Patent number: 11148324
    Abstract: A manual cutting machine includes a base plate. A front support and a rear support are fixedly arranged at two ends of the base plate. Sliding rods are mounted between the front support and the rear support. A slider is disposed around the sliding rods. A connecting block is hinged to the slider. A blade and a presser foot are connected to the bottom of the connecting rod. A push rod is connected to the top of the connecting block. The tail of the push rod is angled relative to the push rod. When the manual cutting machine is used for cutting and fracturing a board, motions of arms are reduced, and the motion range of an operator is narrowed, so that the operator can use the machine more easily and effortlessly. Meanwhile, oil can be added into an oil can to lubricate the slider in the using process.

  • Publication number: 20200394789
    Abstract: An optical coherence tomography (OCT) unit provides a mechanism/method for automatic artery and vein identification. The method may be embodied by specialized algorithm or by a machine learning model, such as a support vector machine or neural network. The present method may identify a vascular configuration that forms a vortex structure in the deep capillary plexus (DCP) of an OCT-based (e.g., OCTA) image of a retina. The identified vortex may then be designated a vein, and other vascular structures from other plexuses, such as from the superficial vascular plexus (SVP), that connect to the identified vortex structure are likewise designated veins. Additional criteria, some based on the vein designations, may be used to identify arteries.

  • Patent number: 9548069
    Abstract: The present invention generally relates to a method for forming a smooth gap of a damascene write pole. An opening having a side wall with a first angle with respect to vertical is formed in a fill layer, and a first non-magnetic layer is deposited into the opening by ion beam deposition. The ion beam is delivered to the side wall at a second angle with respect to vertical. The ratio of the first angle to the second angle ranges from about 250 to about 3.5.
