  • Patent number: 10755405
    Abstract: Methods and systems for diagnosing a semiconductor wafer are provided. A first raw image, a second raw image, and a third raw image of the semiconductor wafer are obtained by an inspection apparatus according to graphic data system (GDS) information regarding layout of a target die. A first image-based comparison is performed by a determining circuitry on the first, second, and third raw images, so as to provide a comparison result. The comparison result indicates whether an image difference is present between the first, second, and third raw images.

  • Patent number: 10678984
    Abstract: The available delivery capability (ADC) of a power distribution network with respect to a power transaction is evaluated in real-time. The power transaction involves simultaneous power deliveries from power sources in a source area to loads in a sink area. First, a list of contingencies are ranked in the power distribution network with respect to static security constraints to obtain a subset of top-ranked contingencies. For each top-ranked contingency in the subset, a representation of the power transaction in a steady state of the power distribution network, in a form of parameterized three-phase power flow equations, is solved to obtain a corresponding power delivery capability (PDC) and a corresponding binding constraint among the static security constraints. The reliability of the power transaction in the power distribution network is then evaluated based on, at least in part, a first contingency PDC which is a smallest PDC among obtained corresponding PDCs.

  • Patent number: 8019157
    Abstract: Vehicle segmentation and counting method based on the property of color variation and headlight information combining change detection in nighttime traffic environment (one-way road with coming direction) is provided. The goal is to reduce the effect of ground-illumination that decreases the accuracy of vehicle segmentation. Besides, the amount of traffic flow is calculated and it can be used in other post-applications, such as traffic-flow reporting or controlling.

  • Publication number: 20070095180
    Abstract: A method for cutting a DWDM filter from a substrate is disclosed, including a two-step process having an initial cutting step and a subsequent cutting step. The initial cutting step forms a slot on a substrate according to size requirement of a finished filter product. The slot has a width larger than the thickness of a cutter employed to perform cutting operation on the substrate. The subsequent cutting step, taken in the slot, completely cuts through the remaining thickness of the substrate to separate the filter from the substrate. The two-phase cutting process avoids corner breaking caused by direct contact between the cutter and the coating layers of the substrate.
