  • Patent number: 11941819
    Abstract: A neural network may be used to determine corner points of a skewed polygon (e.g., as displacement values to anchor box corner points) that accurately delineate a region in an image that defines a parking space. Further, the neural network may output confidence values predicting likelihoods that corner points of an anchor box correspond to an entrance to the parking spot. The confidence values may be used to select a subset of the corner points of the anchor box and/or skewed polygon in order to define the entrance to the parking spot. A minimum aggregate distance between corner points of a skewed polygon predicted using the CNN(s) and ground truth corner points of a parking spot may be used simplify a determination as to whether an anchor box should be used as a positive sample for training.

  • Patent number: 11773466
    Abstract: Provided is steel for a wind power gear with improved purity and reliability. The chemical components thereof comprise, in percentages by mass: 0.15-0.19% of C, ?0.4% of Si, 0.5-0.7% of Mn, ?0.012% of P, ?0.006% of S, 1.5-1.8% of Cr, 0.28-0.35% of Mo, 1.4-1.7% of Ni, and 0.02-0.04% of Al, with the balance being Fe and inevitable impurities. A smelting method therefor comprises adding raw materials to a converter for primary melting, transferring same to a refining furnace for refining, carrying out continuous casting after vacuum degassing, and transferring same to a gas protection furnace for electroslag remelting.

  • Patent number: 6847092
    Abstract: A capacitor for a semiconductor device and a method of manufacturing a capacitor for a semiconductor device is disclosed that uses radial current flow. The capacitor includes a semiconductor substrate that includes a plurality of insulation islands. An insulation layer is formed over the semiconductor substrate. Gate electrodes are formed on top of the insulation layer. An array of CD contact pads including a plurality of CD contacts are connected to the semiconductor substrate in a first predetermined number of locations. An array of CG contact pads including at least one CG contact connected to the gate electrodes such that each CG contact is connected to a respective gate electrode above a respective insulation island in a second predetermined number of locations.
