  • Patent number: 9309640
    Abstract: The invention is a rapid deployment oil recovery apparatus (1) comprising a number of interconnected oil recovery sections, denoted as 1?n interconnected oil recovery sections (100) comprised of a fabric or flexible material. An oil accumulator (200) is distal from the breach and an oil interceptor (300) is secured at the breach. Compression tubes (500) at the outer circumference of an oil recovery section (100) seal a leak in the oil recovery section (100) and provide lift to the oil recovery section (100). The 1?n compression tubes (500) and the compression tube sections (550) are positioned by compression tube control lines (555). An air manifold frame (150) is within the oil interceptor (300) and is comprised of air manifold frame first section (153) and 1?n air manifold frame sections (155) comprising an air manifold (160) having an air manifold fluid supply (163).

  • Patent number: 8397194
    Abstract: According to various embodiments of the invention, systems and methods for presenting Layout Versus Schematic (LVS) errors within a layout using a visual circuit representation of the design and highlighting is provided. One embodiment includes overlaying the layout circuit representation on the schematic circuit representation with highlighting that indicates the LVS errors. The method of such an embodiment compares a layout netlist against a schematic netlist in order to identify the layout-versus-schematic errors, generates a graphical representation of the layout netlist and a graphical representation of the schematic netlist, displays an overlay of the graphical representation of the layout netlist with the graphical representation of the schematic netlist and then, highlights the identified layout-versus-schematic errors that are present.
