  • Method and system for implementing efficient trim data representation for an electronic design
    Patent number: 10192018
    Abstract: An improved approach is described to implement trim data representation for an electronic design. Instead of maintaining a gap shape object for every gap in the layout, existing objects adjacent to the gap location are configured to include attributes of the gap shape. The properties of the gap shape can then be derived from the adjacent objects.

  • Apparatus and method for classifying terminating numbers
    Patent number: 6956823
    Abstract: An identification system includes a modem and a dialog processing device in communication with a telephonic network to identify and classify a multiple of terminating connections. A classification algorithm attempts to establish an analog modem connection using the modem and also monitors operation of the dialog processing device. In response to the modem and the dialog processing device, a controller classifies the terminating connection then writes the type to the database. The classification algorithm will then loop back to the next terminating connection listed in the terminating connection field.
